Upper tool mounting structure for fin transecting die

Abstract

The invention discloses an upper tool mounting structure for a fin transecting die; the upper tool mounting structure comprises an upper tool holder; one end of the upper tool holder is provided with a sliding plate and a limiting post, the sliding plate is vertically movably disposed on the upper tool holder, an upper tool is connected to the lower end of the sliding plate, the sliding plate is provided with an elongated hole, one end of the limiting post is abutted to the upper tool holder, the other end of the limiting post is passed through the elongated hole and is provided with a non-lubricating slider, one side of the non-lubricating slider is attached to the sliding plate, the other side of the non-lubricating slider is provided with a first fitting end face and is provided with a cover plate, the area of a part of the cover plate fitting the first fitting end face is not less than 80% of that of the first fitting end face, and the cover plate is fixedly connected with the upper tool holder. The area of the part of the cover plate fitting the first fitting end face of the non-lubricating slider is not less than 80% of that of the first fitting end face, tight fit between the non-lubricating slider and the sliding plate is effectively guaranteed, loosening is avoided occurring just after using for a period of time, and transecting quality is guaranteed accordingly.

Description

technical field [0001] The invention relates to a fin die, in particular to an upper knife installation structure of a fin cross-cut die. Background technique [0002] With the increasingly fierce competition in the air conditioner market and the ever-changing products, people have higher and higher requirements for the quality and performance of air conditioners. The air-conditioning fin die is a die used to produce air-conditioning fins, which is a high-precision cold stamping progressive die. The fin cross-cutting die is an important part of the air-conditioning fin die. It is the last process of the air-conditioning fin die. Its function is to cut the fins transversely. The fin cross-cutting die on the existing market, its upper knife 11 is installed on the sliding plate 12 of square structure, as figure 1 As shown, the sliding plate 12 is driven by the cylinder to slide up and down, and the sliding plate 12 is located between the upper knife seat 11 and the oil-free l...

Problems solved by technology

[0003] The purpose of the present invention is to address the above problems, to provide a mounting structure for the upper knife of the fin cross-cutting die, to solve the problem that the upper knife of the existing fin cross-cutting die is installed on the sliding plate, and after a period of use, no oil lubricating block There will be a gap between the sliding plate and the looseness, which will affect the gap between the knife edge and the problem of cross-cutting quality.
