Water expansion equipment

Abstract

Provided is water expansion equipment. The water expansion equipment includes a bottom plate, an upper template, a first lower cavity, a second lower cavity, a third lower cavity, a first upper cavity, a second upper cavity, and a third upper cavity. The bottom plate and the upper template are same in structure and symmetrical vertically, and iron pads are arranged on the upper template. As the first lower cavity, the second lower cavity, the third lower cavity, the first upper cavity, the second upper cavity and the third upper cavity are independent and can be directly taken out for replacement, the problem of inconvenient maintenance of a chain structure is avoided, the working efficiency is improved, and the cost is reduced. The equipment is connected with an upper connection plate through the arrangement of an external lifting mechanism, and control is achieved by a lifting servo motor, so that the upward movement amount of the upper template can be controlled. Moreover, inserts in insert grooves formed in the left and right end faces of the outer sides of the first lower cavity, the third lower cavity, the first upper cavity and the third upper cavity can be disassembled andreplaced, the market blank is filled, the qualification rate of forming is high, the efficiency is high, and the expansion quality of a pipe is guaranteed.

Description

technical field [0001] The invention relates to the technical field of water expansion tubes, in particular to a water expansion device. Background technique [0002] The existing molds for the production of automotive pipe fittings are generally controlled by hydraulic pressure, and the operation risk is relatively high. When the pipe fittings are formed, the liquid pressure in the hydraulic system is extremely high. If the pipe leaks, it is very easy to cause injury to the workers. Secondly, the existing molds for the production of automotive pipe fittings generally adopt a chain structure. However, the chain structure molds have problems such as high processing costs, cumbersome processing, large amount of consumables, inconvenient maintenance, and short service life. Contents of the invention [0003] The purpose of the present invention is to provide a water swelling device to solve the problems raised in the background art above. [0004] The purpose of the present...
