A punching head for flexible material cutting and its control method

Abstract

The invention relates to a punching head used for cutting a flexible material and a control method thereof. The punching head comprises a connecting rod, a blade fixing frame, a rotation driving mechanism, a vertical driving mechanism, a directional guide sleeve and a guide part. The blade fixing frame is arranged at the lower end of the connecting rod. A hollow pipe body is arranged in the directional guide sleeve. One end of the connecting rod penetrates through the directional guide sleeve to be fixed to the blade fixing frame, and the other end of the connecting rod is rotatably connected with the vertical driving mechanism. A directional groove is formed in the side wall of the directional guide sleeve. The guide part is fixed to the connecting rod. The punching head and a punching blade can cut the multi-layer flexible material, the requirement for the adsorption capacity of the material is low, the problems that a vibration cutter used for cutting is liable to be deformed and the multi-layer material moves during cutting are solved, the production requirement of users is met, and the work efficiency is improved. The control method achieves automation and intelligence, the completed cutting effect is good, and the market prospects are promising.

Description

technical field [0001] The invention relates to the technical field of material cutting tools, in particular to a punching head for flexible material cutting and a control method thereof. Background technique [0002] At present, the cutting method of flexible materials such as fiber materials and textiles generally adopts vibrating cutter head cutting. Vibrating cutter head cutting uses high vibration frequency (motor speed is 17200r / min, vibration amplitude is 1mm), and the blade blade is high-speed relative to the thickness direction of the material. Vibrates back and forth, and at the same time moves along the track to cut the material, such as Figure 5 shown. [0003] When the above-mentioned cutting method cuts the above-mentioned products, there will be certain resistance along the direction of the cutting track, which will cause the surface of the material to shift, so the cutting of the vibrating cutter head has a higher requirement for the vacuum adsorption force ...

AI Technical Summary

Problems solved by technology

[0003] When the above-mentioned cutting method cuts the above-mentioned products, there will be certain resistance along the direction of the cutting track, which will cause the surface of the material to shift, so the cutting of the vibrating cutter head has a higher requirement for the vacuum adsorption force of the adsorption platform; when the number of material layers increases and When the thickness becomes larger, in the process of cutting multi-layer materials, the upper layer of the material is often not firmly adsorbed, which will cause the material to move during cutting, the cutting accuracy will decrease, the cutting will be deformed, and the product will have problems such as wire drawing and slow cutting speed, which are serious. Affect cutting efficiency and cutting quality
