Piercing die for piercing in sidewall of round tube

Abstract

The invention provides a piercing die for piercing in a sidewall of a round tube and belongs to the field of dies. The piercing die comprises an upper die holder and a lower die holder; the upper die holder is connected with the lower die holder through a guide column; the bottom of the upper die holder is connected with an upper terrace die; a round tube holding portion is longitudinally arranged on the lower die holder; the lower die holder is further connected with a positioning mechanism; the positioning mechanism comprises a driving assembly, a transmission assembly and a positioning assembly, all of which are orderly connected with each other; the positioning assembly comprises a columnar positioning rod that can be driven by the driving assembly to move in a longitudinal direction; when the round tube is placed on the round tube holding portion, the positioning rod can be inserted into the round tube while moving. Such a piercing die is capable of quickly and accurately piercing the sidewall of the round tube; a machined workpiece has the characteristics of high quality and high accuracy and is capable of meeting the requirements of modern production.

Description

technical field [0001] The invention relates to the field of molds, in particular to a punching die for punching holes on the side wall of a circular tube. Background technique [0002] In the field of mechanical processing, it is often necessary to process holes on the side wall of the round tube. The traditional processing methods are mostly processed by drilling or milling. These processing methods are too inefficient to meet the needs of modern production. [0003] In recent years, some punching dies have appeared, which can punch holes on the side wall of the round tube, but the structural design of these punching dies is not reasonable enough, and the material of each round tube in the process of making the round tube is not uniform enough to cause each round tube The mechanical properties of the pipe are inconsistent, so that the round pipe is easy to be squeezed and deformed during the punching process, resulting in the scrapping of the round pipe, which not only inc...

[0002] In the field of mechanical processing, it is often necessary to process holes on the side wall of the round tube. The traditional processing methods are mostly processed by drilling or milling. These processing methods are too inefficient to meet the needs of modern production.

[0003] In recent years, some punching dies have appeared, which can punch holes on the side wall of the round tube, but the structural design of these punching dies is not reasonable enough, and the material of each round tube in the process of making the round tube is not uniform enough to cause each round tube The mechanical properties of the pipe are inconsistent, so that the round pipe is easy to be squeezed and deformed during the punching process, resulting in the scrapping of the round pipe, which not only increases the production cost, but also reduces the efficiency; even damages the punching die and other times. , seriously affecting the normal production work
