Punching device for handmade leather manufacturing

Abstract

The invention relates to a handmade leather manufacturing punching tool, in particular to an assembly type punching device for handmade leather manufacturing. The punching device comprises a knocking handle and a hole-shaped mould positioned on the head position of the knocking handle, wherein a slide rail is arranged on the head position of the knocking handle; the slide rail is positioned on the inner plate surface of a fixed plate; the lower end of the fixed plate and one side of the top end surface of the knocking handle are fixed into an integer; a slide plate is arranged on the slide rail; a slide slot which is matched with the slide rail is formed in the inner plate surface of the slide plate; the slide rail is positioned in the slide slot; at least three bearing table holes are formed in the top of the slide plate; hole-shaped moulds are inserted into the bearing table holes; three slide surfaces of the slide rail and three slide surfaces of the slide slot are integrally formed into a wedge-shaped locking slide surface; and under action of external force, the slide slot only can transversely slide on the slide rail. The punching device improves working efficiency, reduces use cost, realizes free random replacement of hole-shaped moulds and convenient later-stage maintenance, and realizes a self-adaptive punching design.

Description

technical field [0001] The invention relates to a punching tool for handmade leather, in particular to a punching device for handmade leather which improves work efficiency, reduces use cost, and can freely replace hole-shaped molds and adjust hole-shaped mold spacing. Background technique [0002] Existing brand leather and private custom leather are generally handmade by artisans. This type of leather generally includes bags, wallets, watch straps or belts, etc. It is inevitable to punch holes in the handmade process of this kind of leather for subsequent threading and molding. [0003] The punching device of the prior art generally includes a knocking handle, and a hole-shaped mold fixed at the head position of the knocking handle. This kind of punching device seriously restricts the work efficiency of craftsmen. For different types of leather, different leather raw materials and different styles of the same type of leather, it is necessary to customize the punching dev...

Problems solved by technology

This results in a large number of punching devices with different hole shapes and different pitches, and a large investment in tool costs. It takes a long time to clean up the punching devices or find the required punching devices, which is time-consuming and labor-intensive.

Once a hole-shaped mold of the punching device is damaged, the entire punching device cannot be used, and the same punching device must be customized, which is time-consuming and labor-intensive, and the cost is high
