Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of spark machine, concretely to a spark machine with quick cooling liquid function. BACKGROUND

[0002] Electrical discharge machining is also called electric erosion machining, which is a processing method for removing metal materials by local transient high temperature generated by pulse discharge between workpiece and tool electrode. Electrical discharge wire cutting is developed on the basis of electrical discharge forming machining, which uses wire electrode (molybdenum wire or copper wire) to cut workpiece through spark discharge. Electrical discharge wire cutting is mainly used for mold manufacturing and is increasingly used in sample plate, cam, forming tool, precise small parts and processing of special materials.

[0003] Currently, electrical discharge wire cutting mainly uses immersion processing method, that is, workpiece is immersed in cooling liquid for processing, and the waste generated in processing is taken away by cooling liquid. However, the single cooling liquid injection speed from the water inlet is slow, and the injection time is long, which affects the processing efficiency. UTILITY MODEL CONTENT

[0004] In view of the deficiencies of the prior art, the utility model aims to provide a spark machine with quick cooling liquid function to solve the problem of quick cooling liquid in the background art.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical scheme: a spark machine with quick cooling liquid function, comprising a base, a workpiece immersion pool is arranged on the base, a spark machine body is arranged above the workpiece immersion pool, a cooling liquid inlet is arranged on the upper part of one side of the workpiece immersion pool, and a cooling liquid outlet is arranged on the top of the other side, a workpiece mounting seat is arranged in the workpiece immersion pool, a quick cooling liquid feeding mechanism is arranged on the workpiece immersion pool, a cooling liquid inlet pipe is arranged outside the cooling liquid inlet, and a cooling liquid outlet pipe is arranged outside the cooling liquid outlet.

[0006] The quick cooling liquid feeding mechanism comprises a pressure sensor, a cooling liquid inlet branch pipe, a branch cooling liquid pump and a cooling liquid outlet electric control switch, the pressure sensor is fixed on the bottom of the workpiece immersion pool, the cooling liquid inlet branch pipe is fixedly connected to the cooling liquid outlet pipe, the branch cooling liquid pump is fixed on the cooling liquid inlet branch pipe, the cooling liquid outlet electric control switch is fixed on the cooling liquid outlet pipe, and the pressure sensor is electrically connected to the branch cooling liquid pump and the cooling liquid outlet electric control switch.

[0007] As preferred in the utility model, a cooling liquid tank is arranged on one side of the base, a cooling liquid inlet pump is arranged at one end of the cooling liquid inlet pipe, and the cooling liquid inlet pump is arranged in the cooling liquid tank.

[0008] As a preferred embodiment of this utility model, the outlet end of the coolant pipe is connected to a waste coolant collection tank, and the bottom outlet end of the waste coolant collection tank is connected to a sedimentation tank via a conduit. The outlet end of the sedimentation tank is connected to the coolant tank.

[0009] As a preferred embodiment of this invention, the inlet speed of the coolant in the inlet pipe is consistent with the outlet speed of the coolant outlet pipe.

[0010] As a preferred embodiment of this utility model, a filter screen is provided at the liquid outlet of the sedimentation tank, a manual valve A is provided between the sedimentation tank and the coolant tank, and a manual valve B is provided between the waste coolant collection tank and the sedimentation tank.

[0011] As a preferred embodiment of this invention, the sedimentation tank has a cleaning window on its top.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] This invention connects a coolant inlet branch pipe to the coolant outlet pipe, and the coolant inlet branch pipe is directly connected to the coolant tank. When the equipment is started to inject coolant, the coolant inlet pump and the coolant inlet pump in the branch pipe work simultaneously, injecting the coolant in the coolant tank into the workpiece immersion tank through the coolant outlet pipe and the coolant inlet branch pipe, thus achieving the purpose of rapid coolant injection and saving preparation time.

[0014] This invention incorporates a pressure sensor. When the coolant reaches a specified volume, the pressure sensor detects that the coolant pressure has reached a set value, controlling the coolant inlet pump in the branch pipe to stop working and the coolant outlet switch to open. This keeps the workpiece immersion tank in a single-pump inlet state, with the coolant inlet speed and coolant outlet speed being consistent, thus ensuring that the coolant level in the workpiece immersion tank remains constant.

[0015] This invention features manual valves A and B installed at both ends of a sedimentation tank. When there is excessive sediment in the sedimentation tank, both manual valves A and B are simultaneously closed, causing the sedimentation tank to detach from the coolant tank and waste coolant collection tank. Then, the cleaning window is opened for cleaning, which is convenient, quick, and extends the service life. Attached Figure Description
