Problems solved by technology

[0003] In order to solve the problem that the punch seat and the blade of the punch in the prior art are integrally formed, the blade is gradually consumed due to wear and tear, which leads to the scrapping of the punch and increases the cost, and the punch punches the product, and burrs are easily formed on the fracture surface of the product. The problem of product quality is reduced, and the invention provides a burr-free and convenient punch with simple structure, quick disassembly of the blade, and low cost of use.

Embodiment Construction

[0010] The present invention will be further described below in conjunction with the accompanying drawings.

[0011] Such as figure 1 As shown, a burr-free convenient punch includes a punch seat 1, a screw 4, a nut 5 and a blade 3. One side of the punch seat 1 is recessed inwardly to form a groove 2, and in the groove 2 A blade 3 is provided, the screw rod 4 passes through the rear end of the blade 3 and the part of the punch seat 1 on both sides of the groove 2, and the part where the screw rod 4 passes through the punch seat 1 is locked and fixed by a nut 5, the Both sides of the processing end of the blade 3 are provided with rounded corners 6, and the diameter of the rounded corners is 0.1cm-0.4cm. The blade is a rectangular blade.

[0012] The burr-free convenient punch of the present invention is provided with a blade 3 in the groove 2, the screw 4 passes through the rear end of the blade 3 and the punch seat 1 on both sides of the groove 2, and the screw 4 passes thro...

Abstract

The invention discloses a portable punching head without burr. The portable punching head without burr comprises a punching head base, and is characterized by further comprising a threaded rod, a nut and a blade, wherein one side of the punching head base is sunk inwards to form a groove; the blade is arranged in the groove; the threaded rod penetrates the back end of the blade and the punching head base part on the two sides of the groove; the part of the threaded rod penetrating the punching head base is fastened and fixed by the nut; circular beads are arranged on the two sides of the processing end of the blade; the diameter of each circular bead is 0.1 cm to 0.4 cm. The portable punching head without burr solves the problems that the punching head is scrapped and the cost is added as the blade of the punching head in the prior art is integrally molded with the punching head base and is gradually consumed due to abrasion, and the product quality is reduced as burrs are easily formed on a breakage surface of a product when the punching head is used for punching the product; the portable punching head without burr, which is simple in structure, has the blade detached rapidly and is low in use cost, is provided.

Description

technical field [0001] The invention relates to a punch, in particular to a convenient punch without burrs. Background technique [0002] The punch seat and the blade of the current punch are integrally formed. After the blade is used for a long time, it is gradually consumed due to wear and tear. Finally, the blade cannot be used because it is damaged and scrapped. Since the blade and the punch seat cannot be separated, the whole punch is also If it is scrapped, the punch needs to be replaced again, which greatly increases the cost of use and increases the burden on the enterprise. At the same time, the current punch stamping products are easy to form burrs on the fracture surface of the product, which reduces the quality of the product and cannot meet the requirements of some product finishing. Contents of the invention [0003] In order to solve the problem that the punch seat and the blade of the punch in the prior art are integrally formed, the blade is gradually con...
