A punching die capable of quickly adjusting the punching blade

Abstract

The invention relates to the technical field of notching dies and discloses a notching die capable of quickly adjusting a notching blade. The notching die comprises an upper die structure, wherein the upper die structure comprises the notching blade for notch forming and a control strip for adjusting the notching blade and is provided with a blade head and a blade tail, a hanging table is arranged on the side face of the blade tail and is provided with a first tapered wedge face, the control strip is provided with a connecting end and a positioning end, a groove matched with the hanging table is formed in the connecting end, and a second tapered wedge face matched with the first tapered wedge face is formed on the groove. According to the notching die, the first tapered wedge face is arranged on the hanging table of the notching blade, the second tapered wedge face is arranged on the groove of the control strip, and when the groove is matched with the hanging table, the first tapered wedge face is matched with the second tapered wedge face, accordingly the control strip quick pulls out or presses down the notching blade, quick adjustment on notching blade number and the stamping performed by the notching blade is achieved, stamping efficiency is improved, machining time is shortened, and labor intensity is reduced.

Description

technical field [0001] The invention relates to the technical field of notching dies, in particular to a notching die which can quickly adjust a notching blade. Background technique [0002] In the processing of mechanical parts, it is often necessary to process grooves on round tube workpieces. For example, in civil air conditioners, automobile air conditioners and central air conditioners, a pipe for liquid cold and heat exchange is necessary for heating or cooling, and there are two parts in it: a header and a flat tube, and the inner space of the flat tube allows liquid to flow in it In order to transfer heat, if the flat tube is to be connected with the collector to realize a circuit, it is necessary to punch a groove on the collector, and then insert the flat tube into the stamped groove to realize a circuit, and these grooves are usually used The punching die is used for stamping and forming. [0003] At present, the disassembly of the punching blades used for stamp...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to provide a punching die that can quickly adjust the punching blade, aiming to solve the problem of the punching die in the prior art: the punching of any slot position of the flat tube slot on the header cannot be increased or decreased at will. Grooving blades cannot quickly increase or decrease the number of blades participating in the punching groove, resulting in long working hours and low production efficiency
