Round leatherware intermittent punching and cutting positioning device

Abstract

The invention discloses a round leatherware intermittent punching and cutting positioning device. The device structurally comprises a cutting device main body, a bottom control box and a positioning cutting table; the bottom control box is provided with a control motor, a transmission device, a control rotating shaft, a hydraulic cylinder and a hydraulic support rod; and the positioning cutting table is provided with a rotary disc positioning and cutting groove and a leatherware fixing device. The device has the beneficial effects that round leatherware is fixed through the leatherware fixingdevice, through constant-speed rotation of movable rotating discs, and under the assistance of the hydraulic support rod, movable support plates are pushed to raise upwards, so that a blade performs cutting in a cutting groove, and then arc-shaped cutting holes with fixed length are cut; and meanwhile, the distance between the cutting holes is controlled under the uniform motion of the movable rotating discs, the cutting error rate is reduced, and the punching quality of the round leatherware is improved.

Description

technical field [0001] The invention relates to the field of leather goods processing, in particular to a circular leather goods intermittent hole cutting and positioning device. Background technique [0002] There are many kinds of leather goods processing, including a kind of round leather goods that need to be drilled intermittently to facilitate later threading. When drilling, it is necessary to cut a strip-shaped opening with an arc of 1 cm, and it is necessary to measure the distance of the opening with high precision. Otherwise, it will easily lead to uneven cutting between the pores, which will affect the quality of leather processing and cause a lot of waste of raw materials. [0003] Aiming at the current intermittent opening positioning device for round leather goods, a relative solution has been formulated for the following problems: [0004] When cutting and opening, it is necessary to ensure that the length of the opening is consistent, and the distance betwee...

AI Technical Summary

Problems solved by technology

[0004] When cutting and opening, it is necessary to ensure that the length of the opening is consistent, and at the same time, the distance between the pores must be uniform. At the same time, it is necessary to open the pores into an arc-shaped structure. Ordinary blades are straight, which is difficult to meet the requirements of arc-shaped cutting. Demand, even if it can meet the arc-shaped cutting, it is difficult to be accurate to the uniform length of the hole. When cutting high-end round leather goods, it often requires higher-precision equipment for processing
