A batch punching processing device and processing method for sewing leather goods production

Abstract

The invention relates to a batch punching processing device for sewing leather goods, which includes a workbench, a slotting device and a punching device. device, the punching device includes a fixed rod, a large spring, a punching frame, an electric air pump and a hydraulic drive machine, and the present invention drives a slotting tool to slot leather goods through an electric push rod, and the right-angle plate makes the thrust of the electric push rod While pushing the sliding frame horizontally, squeeze the sliding frame vertically downward, so that the grooving tool is in closer contact with the leather goods. The hydraulic drive drives the punching frame to move down to punch the leather goods, and the electric air pump sends the hole to the punching frame. The gas is flushed inside, and the waste produced in the process of punching the leather goods is cleaned by the pressure of the gas, and the inner wall of the hole on the leather goods is cleaned at the same time.

Description

technical field [0001] The invention relates to the field of leather goods processing, in particular to a batch punching processing device and processing method for sewing leather goods production. Background technique [0002] Leather goods are leather furniture or leather tools made of leather. Its manufacturing process includes cutting, bonding, punching, sewing, trimming and edge sealing. Among them, punching is particularly important. It can be said that punching determines the quality of leather goods. The quality of the finished product, therefore, with the progress of society, special devices are required for punching holes during the processing of leather goods. [0003] In the process of punching leather goods, due to the structural limitations of the punching device, there are the following problems in the actual operation process: [0004] (1) With the traditional punching device, after punching the leather goods, the waste after punching cannot be cleaned up in...

AI Technical Summary

Problems solved by technology

[0004] (1) With the traditional punching device, after punching the leather goods, the waste after punching cannot be cleaned up in time, and it is easy to block the punching tool and affect the quality of the punching. Cleaning of leather goods, in severe cases, the punching tool needs to be disassembled, which wastes processing time and even affects the service life of the punching tool

[0005] (2) The traditional punching processing device needs to groove the leather goods before punching the leather goods. One-time slotting will easily make the grooved end surface of the leather goods uneven, which will affect the quality of the groove, and the grooved tool is prone to damage pressure, resulting in damage
