Embodiment Construction

[0033] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0034] According to the flow direction of the electrolyte, the electrolytic machining flow field is divided into three types: forward flow, reverse flow and side flow. figure 1 It is the schematic diagram of the forward flow type, the positive flow electrolytic processing device, the surface roughness of the processed workpiece is higher, and the reverse flow type can significantly reduce the surface roughness of the processed workpiece compared with the forward flow type, a is the cathode of the tool and b is the anode of the workpiece , the electrolyte flows in from the inner cavity of the tool c...

Abstract

The invention relates to the technical field of electrolytic machining devices, in particular to an electrolytic machining device for a counterflow type end cover cavity part, and aims to solve the problems that in traditional machining, a complex cavity is difficult to machine, and the surface roughness of a workpiece is high after positive flow type electrolytic machining. According to the technical scheme, the electrolytic machining device comprises a clamp bottom plate, a cavity electrolytic machining device is arranged on the clamp bottom plate, and a to-be-machined workpiece is arranged between the clamp bottom plate and the cavity electrolytic machining device and is clamped through a workpiece clamp; the cavity electrolytic machining device structurally comprises a waterproof sleeve, a cathode rod, a liquid gathering plate and a cathode head are arranged in the waterproof sleeve from top to bottom, a liquid drainage main flow channel and an inner liquid gathering cavity which communicate in a penetrating mode are formed in the middle of the cathode rod and the middle of the liquid gathering plate, a plurality of liquid return holes are formed in the cathode head, and the liquid return holes communicate with the liquid drainage main flow channel; the lower end surface of the cathode head corresponds to the end cover mold cavity structure.

Description

technical field [0001] The invention relates to the technical field of electrolytic processing devices, in particular to an electrolytic processing device for reverse flow end cap cavity parts. Background technique [0002] With the rapid development of the economy, the gradual improvement of the industrial level, and the increasingly complex structure of human consumption, molds, as an indispensable process equipment, are entering an important period of development. [0003] At present, the shape of product components is complex, the material hardness is high, and the requirements for precision, strength, and toughness are high, which also puts forward higher requirements for the processing of mold cavities. For the cavities of some complex components, it is difficult to meet the requirements through traditional processing, and it is difficult to process parts with large gradients. Because electrolytic machining has a wide range of processing, is not limited by the mechani...
