Mounting structure of longitudinal cutter in sub longitudinal cutting die for fins of air conditioners

Abstract

A mounting structure of a longitudinal cutter in a sub longitudinal cutting die for fins of air conditioners comprises a die holder, a cutter rest and a screw. The screw penetrates out of a connecting block, an extending end of the screw is positioned above a pad, the connecting block is tightly connected with the die holder, the pad is tightly connected with a slider, pins are assembled on the die holder along the periphery of the slider, cap peaks of the pins are in butt joint with the slider, the cutter rest is positioned below the slider, the lower end of one side of the cutter rest for mounting a longitudinal cutting die is tightly connected with a limit block, the other side of cutter rest is tightly connected with the die holder, the front end face and the back end face of the cutter rest are respectively tightly connected with side stop blocks, a stop block is arranged right below the cutter rest, and the stop block is tightly connected with the die holder. The mounting structure is modified from a longitudinal cutter rest structure in the prior art, capable of meeting requirements of various longitudinal cutting manners of the same die, and thus, operators do not need to manufacture different cutter rests with the corresponding specifications.

Description

technical field [0001] The invention relates to an air-conditioning fin mould, in particular to a slitting knife mounting structure in a slitting sub-die in the air-conditioning fin mould. Background technique [0002] The air conditioning fin is an important part of the tube-fin heat exchanger in the air conditioning device, and its main function is to increase the heat exchange area and improve the heat exchange efficiency. Air conditioner fins are generally stamped by air conditioner fin dies. The air-conditioning fin mold includes a plurality of sub-moulds, wherein the slitting sub-die is used to complete the slitting process of making the air-conditioning fin. Slitting is also called stripping. Its function is to cut the entire width of the material into the fin width required by the customer by using the upper and lower knives of the slitting in half. The upper and lower cutters for slitting are respectively fixedly mounted on the upper knife fixed block and the lowe...

AI Technical Summary

Problems solved by technology

On the basis of the structure of the slitting tool holder in the prior art, the tool holders of different specifications are usually used to meet the requirements of several slitting forms for a pair of molds, which is not only wasteful, but also easy to cause confusion
