Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of cutting equipment, in particular to a high-efficiency heat dissipation structure for an electric spark wire cutting machine. Background Art
[0002] Wire EDM is a machine that uses the principle of electric spark discharge for processing. Wire EDM is mainly used to process metal materials of various hardness, especially for processing metal parts with complex shapes and small pores. It has unique advantages. Wire EDM removes metal materials through pulse discharge between a continuously moving fine wire electrode (usually a molybdenum wire or a zinc-coated copper wire) and the workpiece. During the discharge process, a tiny discharge gap is formed between the electrode wire and the workpiece. The metal is eroded by the electric spark in this gap, thereby achieving precise cutting of the workpiece. The workpiece is cut inside the coolant during the cutting process to avoid flying electric sparks and to ensure that the temperature of the workpiece is controlled.
[0003] Although the prior art has many benefits during use, it still has the following problems: it lacks a structure for collecting foam on the surface of the coolant, which causes the foam to accumulate on the surface of the coolant, affecting the worker's observation of the cutting status of the workpiece through the coolant. Utility Model Content
[0004] The utility model aims to provide a high-efficiency heat dissipation structure for an electric spark wire cutting machine to solve the problems raised in the above-mentioned background technology.
[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an efficient heat dissipation structure of an electric spark wire cutting machine, comprising a shell and a drainage groove cutting device body, both sides of the inner wall of the shell are plugged and installed with equidistant and parallel jet pipes, a drainage groove is opened at the upper end of one side of the inner wall of the shell, electric push rods are installed on both sides of the upper end of the inner wall of the drainage groove, and a baffle is installed on the outer wall of the lower end of the electric push rod.
[0006] When using an efficient heat dissipation structure of an electric spark wire cutting machine in the technical solution, the staff places the workpiece on the upper end of the base plate for clamping and fixing, and the cutting equipment body cuts the workpiece. The external air pump conveys pressurized gas to the inside of the connecting pipe and sprays it out through the jet pipe. The flow of airflow pushes the foam on the surface of the coolant to move until the foam accumulates on one side of the baffle. The electric push rod drives the baffle to move up, so that the coolant drives the foam to be discharged through the drainage groove.
[0007] Preferably, a support frame is installed on the upper end of the outer wall of one side of the shell, and a cutting device body is installed on the outer wall of one side of the support frame. The cutting device body can cut the workpiece on the upper end of the bottom plate.
[0008] Preferably, a bottom plate is installed at the lower end of the inner wall of the shell, and the bottom plate is located at the lower end of the cutting device body. The workpiece is clamped and fixed at the upper end of the bottom plate.
[0009] Preferably, the jet pipe is designed in an inclined shape, a connecting pipe is plugged and installed on the outer wall of one side of the jet pipe, and the connecting pipe is located outside the shell. The connecting pipe is connected to an external air pump, and the gas pressurized by the air pump is ejected through the connecting pipe and the jet pipe.
[0010] Preferably, a water level sensor is installed on one side of the inner wall of the shell, and the working height of the water level sensor is lower than the working height of the jet pipe. The water level sensor detects the liquid level of the coolant inside the shell to ensure that the liquid level of the coolant inside the shell is at the lower end position of the drainage groove.
[0011] Preferably, a water inlet pipe is inserted and installed on the outer wall of one side of the shell, and the water inlet pipe is connected to the inside of the shell. The water inlet pipe is connected to an external heat exchange device, so that the coolant can be transported to the inside of the shell after cooling.
[0012] Preferably, a water outlet pipe is plugged and installed on the outer wall of one side of the shell, and the water outlet pipe is connected with the inside of the shell. The coolant inside the shell is discharged through the water outlet pipe.
[0013] Preferably, a sealing gasket is fixedly attached to the outer wall of the baffle, and the sealing gasket is in contact with the inner wall of the drainage groove. The sealing gasket ensures the sealing between the baffle and the drainage groove.
[0014] Compared with the prior art, the utility model has the following beneficial effects: the utility model achieves the effect of cleaning foam by arranging an air jet pipe, a drainage groove and a baffle plate. The staff places the workpiece on the upper end of the bottom plate for clamping and fixing, and the cutting equipment body cuts the workpiece. The external air pump conveys pressurized gas to the inside of the connecting pipe and sprays it out through the air jet pipe. The flow of airflow pushes the foam on the surface of the coolant to move until the foam accumulates on one side of the baffle plate. The electric push rod drives the baffle plate to move up, so that the coolant drives the foam to be discharged through the drainage groove in a centralized manner, thereby achieving the purpose of facilitating the cleaning of foam and facilitating the staff to observe the cutting status of the workpiece through the coolant.
