What is a chip conveyor? What are the types of chip conveyor?

Screw chip conveyor refers to industrial machinery and equipment used to remove debris.  The chip conveyor device is generally installed as close to the cutting area as possible. Such as the lathe chip conveyor device installed in the rotating workpiece below, milling machine and CNC machining center chip conveyor device installed in the bed back to the water tank or the side of the table position, which is conducive to simplify the machine tool and chip conveyor device structure, reduce the machine covers an area, improve chip removal efficiency. The discharged chips generally fall into the chip collection box or car, and some are directly discharged into the workshop chip discharge system. Machine tool chip discharging machine can be divided into chain plate chip discharging machine, scraper chip conveyor machine, permanent magnetic chip discharging machine, screw chip conveyor machine.  Each chip conveyor machine has different performance characteristics and scope of use.  Chain type chip conveyor machine conveying high efficiency, conveying speed selection range;  Scraper chip conveyor machine small volume, high efficiency; Permanent magnetic chip conveyor machine is the use of permanent magnetic material produced by the magnetic field of chip adsorption separation, stable work, long service life; The screw chip conveyor machine is used in mechanical processing, and can be combined with other chip conveyor to form different chip discharging systems.  The most commonly used chip removal devices are the following three:

1. Scraper chip conveyor. The transmission principle of the device is basically the same as the flat chain, but the chain plate is different, it has a scraper chain plate.  This device is often used for conveying short chips of various materials, with strong chip removal ability.  Because the load is large, it needs to use a higher power drive motor.
2. Screw chip conveyor. It works by using a motor to drive a long screw rod installed in the groove through a reduction device.  When the screw rod rotates, the chip in the groove is pushed forward continuously by the screw rod, and finally discharged into the chip collecting box.  There are two kinds of screw rod, one is a flat steel strip rolled into a spiral spring;  The other is a spiral steel plate welded to the shaft.  This device occupies a small space and is suitable for installation in the narrow gap between the machine tool and the column.  Screw chip conveyor structure is simple, chip removal performance is good, can be made level or with lifting height.  Can be single-machine or multi-machine combination.  Simple structure, flexible installation, but only suitable for horizontal or small Angle inclined linear direction of chip discharge, can not tilt, lift or turn to large Angle chip discharge.  General horizontal chip removal can be used without axial helix, with lifting chip removal should be used with axial screw, and increase the diameter of chip removal mouth to increase chip pushing strength, conducive to chip discharge. However, the spiral chip removal machine is not suitable for removing long strip and fibrous metal chips.  Screw chip removal device has a variety of sizes and lengths for customers to choose, can match different machine tools to use. This chip removal device is simple to install and disassemble, and easy to maintain in the later period.
3. Plate chain chip conveyor. The machine uses a rolling sprocket to pull a steel plate chain belt in a closed box, and the scrap metal chips from processing fall on the chain belt and are carried out of the CNC machining center.  This device can eliminate chips of various shapes, and is very adaptable for a variety of machine tools.Chain-plate chipping machine is a multi-purpose material conveying device, especially suitable for conveying chips containing coolant because of its lifting function.  The chain plate is made of stainless steel and high quality carbon steel. The surface can be processed with raised points to prevent the adhesion of fine metal chips. The special structure of the plate chain chip removal device is more suitable for conveying scrap metal under harsh processing conditions.

What are the classifications of the Screw chip  conveyor?

screw chip  conveyor machine is a common equipment in modern processing equipment, which is divided into two types: cored and coreless. The iron scraps collected from the protective cover or workbench are transported to the chip inlet of the chip conveyor and then to the collection vehicle. The bell mouth can also be installed to directly discharge the waste from the bell mouth to the chip collector.

The structure of the screw chip  conveyor machine can be divided into core propulsion, or no conveying groove. Coreless propulsion, with or without conveying trough. Coreless propulsion, with conveying groove lifting type;  Coreless propulsion, conveying trough lifting type and equipped with coolant tank; Spiral chip discharging machine is mainly used for conveying granular, powdery, block and roll chips cut from metal and non-metal materials in the process of mechanical processing. It can be used in CNC lathes, CNC machining centers or other places where the machine tool placement space is relatively narrow.

The screw chip  conveyor can collect and transport all kinds of roll, ball and block chips, as well as copper chips, aluminum chips, stainless steel chips, carbon blocks, nylon and other materials that cannot be solved by the traditional chip conveyor. It is widely used in all kinds of CNC machining centers and flexible production lines. It can also be used as a conveyor for small parts of stamping and cold pier machine tools, In food production and transportation, it can improve the operating environment, reduce labor intensity and improve the automation of the whole machine.

What are the benefits of installing a chip conveyor?

If the CNC machining center does not install chip conveyor machine, then will rely on manual waste chip discharge, will waste a lot of human and material resources, but also affect the production schedule.  No matter what kind of chip discharge conveyor, the main role or the collection of machine tool cutting process generated waste chips, and transport them out of the processing center area, realize the control automation of the processing center.  CNC machining center of high efficiency machine tool, a short period of time generated chip quantity is very large, if not timely cleaning will occupy a lot of processing space.  It can also cause damage to the machine or unable to complete automatic machining of the workpiece because of cutting cover on the workpiece or tool.  Vertical machining center cutting speed is very fast, the chip temperature is very high, a lot of accumulation in the working area will cause the workpiece or CNC machining center deformation, long time will affect the accuracy of vertical machining center.  Therefore, the installation of chip discharging machine can not only reduce the labor intensity of the operator, but also save time to improve output.  The service life and accuracy of vertical CNC machining center have great protection.

Do all CNC machining centers need chip conveyor?

Small vertical CNC machining center can not be equipped with chip conveyor machine, if the use of less frequency and the actual processing process produced not much scrap metal scraps in the case of customers can not install chip discharging machine.  But large CNC machining centers and gantry milling generally need to be equipped with chip conveyor machine.  The chip conveyor machine can discharge chips in time to achieve automatic production and maintenance of CNC machine tools also has a certain role.  The chip discharging machine has a variety of price options, if the customer budget allows the best machine is equipped with chip conveyor machine. In the sales of the CNC machining center, Tsinfa  company will recommend suitable chip conveyor machines according to the actual needs of customers and machine models. Make the best choice for you.

How to solve the common failure of chain plate chip conveyor?

Chain plate chip conveyor is one of the more common chip conveyor.  It is not only suitable for the discharge of long chips, short chips and cluster chips, but also suitable for the transportation of chips of various materials.  The chain plate chip conveyor has strong adaptability, large conveying capacity, long conveying distance, high efficiency and low failure rate.  However, it is inevitable that faults will occur in daily use.  Common faults of chain plate chip conveyor include:

1. Bearings are often damaged.  The operator should check whether the driving gear and the guide gear of the chipping chain plate are consistent;  Whether the chain plate tightening screws are tightening.
2. The waste chips slip on the chain plate and are not easy to discharge.  It may be because the lifting slope is too large.  You only need to slow down the lifting angle, or you can increase the density and height of the scraping plate.
3. The chip removal chain plate is broken. Therefore, customers should often check the waste on the chip removal chain plate to avoid accumulation; Check whether the overload protector operates normally, because occasionally the clutch plate of the overload protector is too tightly locked and cannot play its due protective role.
4. Waste often accumulates too much under the chip removal chain plate and is not easy to discharge. The customer should change the lifting angle at the bottom of the shell to circular arc smooth type to avoid dead angle and easy accumulation of debris; A chip baffle can also be installed at the bottom of the chip outlet.
5. The reduction motor is burnt out.  We can increase the power of the reduction motor or install the motor overload protector.

What are the control types of start and stop of chip conveyor on Vertical CNC machining center?

At this stage, the start and stop of the automatic chip conveyor on our CNC vertical machining center mainly have the following two types: the first is that the chip conveyor has a separate electronic control system and can run independently. It is started and stopped by the operator without the influence of whether the machine tool is started or not. When cutting in the NC machining center, the operator manually starts the chip conveyor. When the NC machining center stops cutting, let the chip conveyor work for another period of time. After the scrap metal is completely transported, the operator can manually shut down the chip conveyor. The second way is that the chip conveyor and CNC vertical machining center are controlled by linkage. When the machining center is started, the chip conveyor is also started at the same time. Cutting and chip removal are carried out at the same time. When the NC machining center stops cutting, the chip conveyor also stops at the same time.

Precautions for using chip conveyor in CNC machining center?

With its excellent product performance and unique working mode, CNC machine tool chip conveyor is widely used in many fields. The chip conveyor is not familiar with many operations. The following points should be paid attention to during the use of the chip conveyor:

1. Before power on, first check the lubricating oil margin of the reducer to see if it is lower than the standard oil level line. If it is lower than the standard oil level line, add the corresponding full loss system oil to the marked oil level line.
2. After the engine of the chip conveyor is started, check whether the rotation direction of the sprocket is consistent with the direction indicated by the arrow marked on the machine. If not, correct it immediately.
3. The sprocket of the chip conveyor device is equipped with an overload safety clutch, and the chip conveyor machine has been adjusted during factory commissioning. After the chip conveyor is started, if the friction plate in the machine is found to slip, stop the machine immediately and check whether there is any foreign matter stuck in the chain belt or other reasons. The motor can not be restarted until the cause of the chip conveyor is clear. At this time, the chip conveyor can operate normally, indicating that the problem has been solved.
