Abstract

The drilling process of carbon fiber composite materials will produce powdery chips, which will pollute the environment and affect the health of workers. However, at present, the chip is sucked away by a vacuum cleaner manually, because it can only be sucked from the hole entrance area, and cannot be sucked directly when it is generated. Aiming at this main problem, the present invention proposes a brand-new processing system—a suction-type self-removing chip processing system for CFRP processing to provide a technical solution for realizing CFRP green processing. The proposed self-suction chip removal system for CFRP machining includes: 1-machine tool, 2-CFRP, 3-drill, 4-tool holder, 5-spindle, 6-cutting channel, 7-suction/storage device. The working principle of the air-breathing chip removal system for CFRP processing is that when the machine tool drives the drill bit to cut the workpiece, the instantaneous chips generated during the drilling process can pass through the suction hole of the tool, pass through the tool holder, the spindle and the chip removal channel. Enter the storage device to realize the green processing of CFRP.

technical field

The invention is applicable to the chip removal process of all processing chips including the processing of carbon fiber composite materials in powder form. In particular, it relates to an air-suction automatic chip removal system for CFRP processing.

Background technique

The drilling process of carbon fiber composite materials will produce powdery chips, which will pollute the environment and affect the health of workers. However, at present, the chip is sucked away by a vacuum cleaner manually, because it can only be sucked from the hole entrance area, and cannot be sucked directly when it is generated. Aiming at this main problem, the present invention proposes and designs a brand-new drilling processing system—air-breathing self-swarf removal drilling processing system, so as to realize green processing of carbon fiber composite materials.

The present invention designs an air-breathing automatic chip removal system, the purpose of which is to remove chips generated during CFRP processing in time and realize green processing.

In order to achieve the above object, the technical solution adopted in the present invention is: a kind of air-breathing self-extraction chip system, which is made up of machine tool, workpiece, drill bit, tool handle, 5-spindle, chip channel, air suction/storage device; and In this system, the workpiece is fixed on the machine tool with fixtures, etc., the drill bit is connected to the tool handle, the tool handle is connected to the spindle, the spindle is connected to the machine tool, and the chip channel is connected to the suction/storage device through the drill bit, tool handle, and spindle. .

The system described is suitable for all chip removal processes in which the machining chips are in powder form.

The machine tool in the system may be any machine tool capable of drilling, such as a milling machine or a drilling machine.

The drill bit in the system can be any type of drill bit with a chip removal channel in the middle and can perform corresponding cutting processing.

In the system described above, the main shaft should have a chip removal channel in the middle and be able to drive the station head to perform corresponding cutting.

The suction/storage device in the system can generate the negative pressure required for sucking out chips and can store the cutting generated by the corresponding tool processing.

The working principle of the system is that when the machine tool is started and the spindle drives the drill bit to drill and process the workpiece, the suction/storage device will generate negative pressure so that the cutting powder produced by the drill bit will be transported to the suction hole through the chip channel of the drill bit, tool holder and spindle. Gas/storage device to achieve green processing of carbon fiber composite materials.

Beneficial effects of the present invention

1. For CFRP processing, the suction type self-absorbing chip removal system, its greatest effect is that the chips generated during CFRP processing can be discharged by the system in a timely manner, so as to avoid the generated chips from polluting the environment and affecting the health of operators. (2) This design creatively proposes that discharging chips from the center of the drill bit can save the machining space for cutting, but the spindle needs to have a cooling channel. (3) This design creatively proposes that the suction/storage equipment can provide the pressure required for suction and the storage space for chips for the self-suction chip removal system, so as to realize the green and environmentally friendly processing of CFRP.
