Fin height adjusting mechanism of fin forming machine

Abstract

The invention relates to a fin height adjusting mechanism of a fin forming machine. The fin height adjusting mechanism of the fin forming machine comprises a machine frame, an upper mold plate, a lower mold plate and a maintaining spring, wherein the machine frame is composed of an upper machine plate, a lower machine plate and a guide column arranged between the upper machine plate and the lower machine plate, and the upper machine plate can move up and down relative to the guide column. The fin height adjusting mechanism of the fin forming machine is characterized in that the fin height adjusting mechanism of the fin forming machine further comprises a supporting spring, limiting wheels, a chain and a motor, the supporting spring is sleeved on the guide column and is sustained between the upper mold plate and the upper machine plate, the limiting wheels are connected to the guide column on the upper portion of the upper machine plate in a threaded mode, driven chain wheels are fixed around the limiting wheels, the chain is meshed with transmission chain wheels in sequence to form a closed ring shape, the motor is installed on the upper machine plate, a driving chain wheel is installed on the output shaft of the motor, and the driving chain wheel is meshed with the chain to drive the chain to move. Compared with an existing fin height adjusting mechanism, the fin height adjusting mechanism has the advantages that due to the fact that four oil cylinders and corresponding control systems are eliminated, cost is greatly reduced; in addition, due to the fact that only the motor needs to work in an adjusting progress, adjusting of the fin height can be carried out even when the machine is in a working state, and working efficiency is high.

Description

technical field [0001] The invention belongs to the technical field of a fin forming machine for a plate-fin heat exchanger, and in particular relates to a fin height adjusting mechanism of a fin forming machine. Background technique [0002] Plate-fin heat exchangers are heat exchangers for various types of gas separation equipment. They are widely used in petrochemical, aerospace and other fields. Plate-fin heat exchangers have the advantages of compact structure, light weight, and high heat exchange efficiency. Thermal 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 entire heat exchanger volume. The precision of fins directly affects the heat transfer efficiency, reliability and safety performance of plate-fin heat exchangers. [0003] At present, there are also forming machines specially used to produce fins on the market. For example, the Chinese utility model patent "A B...
