Abstract

The invention relates to plug processing equipment and aims to provide plug forming equipment which is convenient to use, high in processing efficiency and reliable in product performance. The processing steps includes: arranging a steel plate to be processed on a worktable, setting a sealing part between the edge of the steel plate and the worktable, setting a forming ring die at the edge of the steel plate, translating a pressing oil cylinder or air cylinder to the forming ring die through an adjusting mechanism, pressing the forming ring die with the steel plate and the sealing component by the operating pressing oil cylinder or air cylinder, filling high-pressure liquid between the worktable and the steel plate through a high-pressure pipe by a high-pressure pump so that the steel plate is expanded and deforms; detecting whether the steel plate deforms sufficiently or not by a sensor arranged at the plug, controlling the high-pressure pump to maintain pressure for some time by a control system connected with the sensor after deformation is sufficient, taking off the deformed steel plate and cutting edges of the steel plate after pressure is released, and obtaining a finished plug. The plug forming equipment is high in automation degree, and production efficiency and safety are remarkably improved.

Description

technical field [0001] The invention relates to a head processing equipment and method, in particular to a head processing equipment and method using liquid pressure. Background technique [0002] Many special-purpose vehicles such as tank trucks, sprinklers, and garbage trucks are equipped with tank bodies, which are composed of a central cylinder and end heads connected; these heads are usually in the shape of concave shells. [0003] In the prior art, there are usually the following processes for head processing: [0004] Hot stamping method: the plate is heated and then pressed into shape using male and female molds. This technology requires large-tonnage molds and pressure equipment to form. And the heating of the steel plate will have an adverse effect on the properties of the plate. [0005] Pressing method: the sheet is rotated and fed by a rotary wheel to realize rotary plastic forming. The process is slow and the cost of special equipment is high, and the proce...
