Embodiment Construction

[0016] The present invention will now be further described in detail in conjunction with the accompanying drawings and embodiments. These drawings are all simplified schematic diagrams, only illustrating the basic structure of the present invention in a schematic manner, so it only shows the composition related to the present invention.

[0017] Such as Figure 1 to Figure 3 As shown, a square hole punch used on a lathe includes a guide head 20, a punch body 10, a resisting portion 40, and a positioning seat 50 arranged axially from top to bottom. The cross section of the punch body 10 It is square, and the guide head 20 is arranged on the end of the punch body 10. The orthographic projection of the guide head 20 is trapezoidal and narrow at the top and wide at the bottom. In the present invention, the cross section of the guide head 20 is also square. The transition surface 30 of 10 is an inclined surface, and the inclination angle of the transition surface 30 is smaller than...

Abstract

The invention relates to a square hole punch chip used on a punch press. The square hole punch chip used on the punch press comprises a punch chip body of which the cross section is square, the end of the punch chip body is provided with a guide head of which the orthographic protection is trapezoidal, the upper portion of the guide head is narrow, the lower portion of the guide head is wide, the cross section of the guide head is square, the transition face of the guide head and the punch chip body is a slope, and the inclination angle of the transition face is smaller than the base angle of the guide head. According to the square hole punch chip used on the punch press, the expansive force of outward deformation of products is increased through the guide head, and consequently positive pressure on the punch chip body from the products is decreased; the contact face of the punch chip body and the products is enlarged through the inclined transition face, impact force between the punch chip body and the products is reduced, and consequently the square hole punch chip is more resistant to abrasion and longer in service life, and the stamping effect of a square hole is ensured.

Description

technical field [0001] The invention relates to the field of punch processing, in particular to a punch for processing square holes on a punch. Background technique [0002] In the prior art, the processing of square holes on the product is realized by using a punching machine. A square hole punch is installed on the punching machine, and the punch is aligned with the position to be punched on the product to form a square hole on the product. The traditional square hole punch is an elongated cylinder with a square cross section. After repeated hedging, the end of the square hole punch is worn, and the square hole punch needs to be replaced frequently to ensure the processing requirements of the square hole. The traditional square hole punch has low productivity, and frequent replacement of the square hole punch increases the processing cost of the product. Contents of the invention [0003] The invention overcomes the shortcomings of the prior art and provides a squar...
