Sheet bar stacking clamping jaw

Abstract

The invention discloses a sheet bar stacking clamping jaw which comprises a jaw body (5), a first swing arm (2), a second swing arm (16), an air inlet and exhaust reversing valve, a swing arm resetting spring (4), a piston resetting spring (6), a first clamping plate (1) and a second clamping plate (15), wherein the first end of the jaw body (5) is provided with a cylinder body for mounting a piston (7); the first swing arm (2) and the second swing arm (16) are hinged to the second end of the jaw body (5) in an X shape through a pin shaft (3); the air inlet and exhaust reversing valve is connected with the first end of the jaw body (5); the swing arm resetting spring (4) is positioned between the first swing arm (2) and the second swing arm (16); the piston resetting spring (6) is positioned in the cylinder body of the jaw body (5) and pushes the piston (7) to be reset; the first clamping plate (1) and the second clamping plate (15) are connected with the second ends of the first swing arm (2) and the second swing arm (16); the second end of the piston (7) is provided with a conical concave cavity; the first ends of the first swing arm (2) and the second swing arm (16) are connected with the conical concave cavity of the piston (7) in a sliding manner.

Description

technical field [0001] The invention relates to an assembly device of a plate heat exchanger, in particular to a plate stack clamp. Background technique [0002] The plate heat exchanger is a high-efficiency heat exchanger composed of a series of metal sheets with a certain corrugated shape. The corrugated plates are generally made of corrugated plates by punching thin plates. The assembly of plate heat exchangers is a complicated, time-consuming and laborious installation process. Generally, the assembly of plates by manufacturers is to manually stack two plates. Inlaid, the tools used are hand pliers. This traditional assembly method makes the labor intensity of the workers very high, and the labor production efficiency is extremely low. Moreover, because it is manual operation, the clamping force used each time must be different, and the product quality is difficult to be guaranteed. Contents of the invention [0003] In order to overcome the defects of the prior art,...
