Problems solved by technology
[0004] However, due to the large structure of the integral liquid cooling plate, the use of stamping or inflation molding cannot meet the forming requirements due to the limited tonnage of the existing hydraulic equipment. If the tonnage of the equipment is increased to solve this problem, it will bring greater costs. put in

Embodiment Construction
[0027] In order to make the above objects, features and advantages of the present invention more comprehensible, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.
[0028] One of the core concepts of the embodiment of the present invention is that, in the case of only providing a rated limited pressure environment, the expansion plate forming mold is divided into multiple sections for separate inflation, so that the single inflation area is reduced, resulting in a unit area The greater the pressure, the faster the flow channel of the expansion plate is formed, and the effect is better, and there is no need to replace the pressure-providing equipment because of the size of the expanded plate to be processed, and the production efficiency and economic benefits are improved.
[0029] The expansion plate mentioned above is the channel plate that provides the cooling medium to flow in the heat diss...

Abstract
The invention relates to the technical field of plate machining, and particularly relates to a segmented machining method for an expansion plate. The segmented machining method comprises the steps that a male die and a female die matched with the male die are preassembled; a to-be-machined blank plate covers the surface of a runner forming groove of the female die; die assembly is conducted, a to-be-machined blank deforms, a plurality of first sealing rings are attached to the surface of the to-be-machined blank plate, and a plurality of closed cavities are formed between the to-be-machined blank plate and the male die; and a fluid medium is injected into the multiple closed cavities along a blowing-up hole in the male die till the preset pressure intensity value is reached in the closed cavities, the runner forming groove of the to-be-machined blank plate deforms under the pressure of the fluid medium, and the expansion plate is obtained. When the expansion plate large in specification is actually produced, pressure intensity equipment matched with the expansion plate does not need to be replaced, and the production efficiency and economic benefits are improved in a segmented machining manner.
Description
technical field [0001] The invention relates to the technical field of plate processing, in particular to a segmented processing method of an expanding plate. Background technique [0002] With the continuous development of new energy vehicles, the energy density of new energy vehicle battery packs has attracted more and more attention from manufacturers and consumers, and has even become a key factor in judging the performance of the vehicle. The heat dissipation of the battery pack module also forms a thermal management system based on the heat dissipation requirements of the whole vehicle. The battery pack has changed from the original cell-module-battery pack to the cell-battery pack. [0003] The original split liquid cold plate has also become a monolithic structure with the high integration of battery packs. [0004] However, due to the large structure of the integral liquid cooling plate, the use of stamping or inflation molding cannot meet the forming requirements ...
