Upper die fixed type fin forming machine

Abstract

The invention relates to an upper die fixed type fin forming machine. The upper die fixed type fin forming machine is characterized by comprising a machine frame, a lower die plate, a retaining spring, two shifting rods, a transmission shaft, a cam driving structure and a stripping structure, wherein the machine frame is composed of an upper machine plate, a lower machine plate and a guiding column, an upper die installation plate is installed on the upper machine plate, the lower die plate is arranged on the lower portion inside the machine frame and can slip up and down along the guiding column, a lower die installation sliding plate is arranged above the lower die plate, the guiding column is sleeved with the retaining spring which is supported between the upper machine plate and the lower die plate, the left and right shifting rods are arranged vertically in a spaced mode, penetrate through the lower die plate upwards and then are connected with the lower die installation sliding plate, the transmission shaft is driven by a motor to rotate, the cam driving structure is arranged inside the machine frame, located below the lower die plate and arranged between the transmission shaft and the lower die plate, and the stripping structure is arranged between the lower die plate and the upper machine plate. Due to the fact that the upper die does not need to do the vertical stamping action, an upper driving shaft, an upper die plate and a cam driving structure between the upper driving shaft and the upper die plate in the prior art can be eliminated, and the precision influence generated by abrasion of a universal coupler in an existing structure is eliminated.

Description

technical field [0001] The invention belongs to the field of stamping and forming machine tools dedicated to fins, in particular to a fin forming machine with a fixed upper die. Background technique [0002] Aluminum fins are widely used in automotive aluminum water tank radiators, parallel flow condensers, parallel flow evaporators, radiators or surface coolers, variable air volume air conditioning cabinets, fan coils and heat exchangers. The main function of the component is to dissipate heat. The plate-fin heat exchanger has the advantages of compact structure, light weight, and high heat exchange efficiency, especially the heat exchange efficiency is 30% higher than other heat exchangers. Fins are the key components of plate-fin heat exchangers, accounting for more than 80% of the volume of the entire heat exchanger. The precision of fins directly affects the heat transfer efficiency, reliability and safety performance of plate-fin heat exchangers. [0003] There are fo...

Problems solved by technology

However, the above-mentioned high-precision reciprocating feeding mechanism has the following disadvantages: the pusher rod is a whole in its structure, and when the left and right pushers cannot be horizontally and parallelly fed due to the difference in the gap, they cannot be adjusted.

In addition, the front and rear guide points of the push rod are located inside the hinge seat, the distance between the guide points is too small, and the guide accuracy is not high
