Description

Technical Field

[0001] This utility model relates to the field of EDM technology, specifically to an EDM machine with a cooling function. Background Technology

[0002] A discharge machining (DDM) machine is a type of machining equipment primarily used for electrical discharge machining. It is widely used in the manufacture of various metal molds and mechanical equipment. It is a special machining method that utilizes the electro-erosion effect generated by pulsed discharge between two electrodes immersed in a working fluid to remove conductive materials; it is also known as electrical discharge machining or electro-erosion machining.

[0003] Based on the above, the inventors have discovered the following problem: During the EDM process, the high temperature generated by the discharge will cause the surface material of the workpiece to vaporize and melt, forming waste chips. If these waste chips are mixed with the working fluid and cannot be separated in time, they are very likely to accumulate in the connection channel between the working fluid and the cooling system, affecting the normal flow of the working fluid and ultimately causing the working fluid to be unable to cool the workpiece normally.

[0004] Therefore, in view of this, we will study and improve the existing structure and its shortcomings to provide a spark dynamometer with a cooling function, in order to achieve a more practical value. Summary of the Invention

[0005] The purpose of this invention is to provide an EDM machine with a cooling function to solve the problem mentioned in the background art, which is that the mixing of working fluid and waste chips causes blockage of the cooling system connection channels and reduces cooling efficiency.

[0006] In view of the above problems, the technical solution proposed by this utility model is as follows:

[0007] A spark dynamometer with a cooling function includes a housing, a collection mechanism, and a filtering mechanism. The spark dynamometer body is installed on one side of the housing. The collection mechanism includes a cover plate with a collection groove installed on its upper surface. The bottom end of the cover plate is connected to the upper end of the housing. The filtering mechanism includes a separation box and an inner box. A pair of magnetic rollers are rotatably connected inside the separation box. Separation grooves are formed on both sides of the separation box. Inclined plates are installed inside the separation grooves. The two opposite ends of the inclined plates abut against the pair of magnetic rollers. A partition is installed on the upper end of the inner box. The bottom end of the separation box is connected to the upper surface of the partition. Slots are formed on both sides of the upper surface of the partition. Filter baskets are inserted into the slots. A filter box is inserted into the inner box. The bottom end of the inner box is connected to the inner bottom end of the housing.

[0008] Furthermore, a transmission box is installed at one end of the separation box, and one end of each pair of magnetic rollers extends through the separation box into the interior of the transmission box, and each is fitted with a gear, with the pair of gears meshing with each other.

[0009] The beneficial effect of adopting the above-mentioned further solution is that, in the transmission box at one end of the separator, a pair of meshing gears are respectively fitted on the magnetic rollers, which can ensure that the pair of magnetic rollers rotate synchronously in opposite directions, so that the coolant can come into more full contact with the magnetic rollers when passing through the magnetic rollers, thereby improving the adsorption efficiency of ferromagnetic impurities.

[0010] Furthermore, a servo motor is fixedly installed on one side of the transmission box, and the output end of the servo motor is connected to one of the gears.

[0011] The beneficial effect of adopting the above-mentioned further solution is that the servo motor on one side of the transmission box is connected to one of the gear transmissions to provide power for the rotation of the magnetic roller. The rotation speed of the magnetic roller can be controlled according to actual needs, thereby adjusting the impurity adsorption effect.

[0012] Furthermore, a hopper is installed at the upper end of the separation box, and a water guide trough is installed at the center of the hopper.

[0013] The beneficial effect of adopting the above-mentioned further solution is that the hopper at the top of the separator and the water guide trough at the center can guide the collected coolant and impurities into the separator, so that the working fluid is exactly between a pair of magnetic rollers. When the magnetic rollers rotate in opposite directions, the adsorbed waste can come into contact with one end of the inclined plate. The inclined plate scrapes the waste off the magnetic rollers, allowing the waste to enter the filter basket smoothly.

[0014] Furthermore, a glass fiber filter layer is installed at the bottom of the filter box, and a nylon mesh filter layer is installed above the glass fiber filter layer inside the filter box.

[0015] The beneficial effects of adopting the above-mentioned further solution are that the glass fiber filter layer and the nylon mesh filter layer in the filter box can filter out small particulate impurities, while the nylon mesh filter layer can intercept larger impurities. Through multi-stage filtration, the cleanliness of the working fluid is further improved, and blockage of the pipeline is avoided.

[0016] Furthermore, a heat exchanger is fixedly installed on one side of the bottom of the inner chamber. The heat exchanger's heat medium inlet is connected to the bottom of the inner chamber through a pipe. A pump is fitted on the heat medium outlet of the heat exchanger. The heat exchanger's cold medium inlet pipe and cold medium storage pipe both extend through the chamber to the outside.

[0017] The beneficial effects of adopting the above-mentioned further solution are that the heat exchanger on one side of the bottom of the box has its heat medium inlet end connected to the bottom of the inner box through a pipe, which can introduce the filtered coolant into the heat exchanger for cooling. The pump is installed at the heat medium outlet end to provide power for the circulation of the working fluid. The coolant inlet pipe and coolant storage pipe run through the box and extend to the outside, which facilitates the connection of the heat exchanger with external cooling equipment to promote its heat exchange effect, reduce the temperature of the working fluid, and realize the cooling function.

[0018] Furthermore, a spray pipe is installed on one side of the upper end of the cover plate, and the bottom end of the spray pipe is connected to the output end of the pump.

[0019] The beneficial effect of adopting the above-mentioned further solution is that the spray pipe on the upper side of the cover plate is connected to the output end of the pump. The pump delivers the cooled working fluid to the spray pipe, which can spray the working fluid onto the processing part of the EDM machine body, thereby playing a role in cooling and lubrication, and improving the processing efficiency and quality of the EDM machine.

[0020] Furthermore, a drainage trough is provided on one side of the bottom of the collection trough, and the bottom of the drainage trough is located on the upper side of the hopper.

[0021] The beneficial effect of adopting the above-mentioned further solution is that the drainage trough on one side of the bottom of the collection tank, with the bottom of the drainage trough located on the upper side of the hopper, allows the working fluid and impurities collected in the collection tank to flow smoothly into the hopper and enter the filtration mechanism for processing, thereby realizing the recycling of the working fluid and saving resources.

[0022] Compared with the prior art, the beneficial effects of this utility model are as follows: This EDM machine with cooling function has a housing that provides support and protection for the entire machine. The EDM machine body, mounted on one side of the housing, is the core component for EDM processing. The cover plate of the collection mechanism connects to the housing, and its collection trough collects the working fluid used for cooling during processing. The magnetic roller and inclined plate in the separation box of the filtration mechanism work together to magnetically adsorb ferromagnetic impurities in the working fluid. The inner box and its filter basket and filter box can perform multi-stage filtration of the working fluid, improving the cleanliness of the coolant, preventing debris from clogging the pipes, and facilitating subsequent cooling. In preparation for circulation, the hopper at the top of the separator and the water guide trough in the center guide the collected coolant and impurities into the separator, ensuring the working fluid is positioned precisely between a pair of magnetic rollers. When the magnetic rollers rotate in opposite directions, the adsorbed waste particles come into contact with one end of the inclined plate. The inclined plate scrapes the waste particles off the magnetic rollers, allowing them to smoothly enter the filter basket. Inside the filter basket, there are glass fiber filter layers and nylon mesh filter layers. The glass fiber filter layer filters out tiny particles, while the nylon mesh filter layer intercepts larger impurities. This multi-stage filtration further improves the cleanliness of the working fluid and prevents pipe blockage. Attached Figure Description

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Please see Figure 1 - Figure 5A transmission box 10413 is installed at one end of the separation box 10401. One end of each pair of magnetic rollers 10405 extends through the separation box 10401 into the interior of the transmission box 10413, and each roller is fitted with a gear 10415. The gears 10415 mesh with each other. A servo motor 10414 is fixedly installed on one side of the transmission box 10413. The output end of the servo motor 10414 is connected to one of the gears 10415. A hopper 10402 is installed at the upper end of the separation box 10401. A magnetic roller is installed at the center of the hopper 10402. The filter box 10409 has a water guide channel 10403. A glass fiber filter layer 10412 is installed at the bottom of the filter box 10409. A nylon mesh filter layer 10411 is installed above the glass fiber filter layer 10412 inside the filter box 10409. Inside the transmission box 10413 at one end of the separation box 10401, a pair of meshing gears 10415 are respectively fitted onto magnetic rollers 10405, ensuring that the pair of magnetic rollers 10405 rotate synchronously in opposite directions. This allows the coolant to more fully contact the magnetic rollers 10405 as it passes through them. To improve the adsorption efficiency of ferromagnetic impurities, a servo motor 10414 on one side of the transmission box 10413 is connected to one of the gears 10415, providing power for the rotation of the magnetic roller 10405. The rotation speed of the magnetic roller 10405 can be controlled according to actual needs, thereby adjusting the impurity adsorption effect. The hopper 10402 at the top of the separation box 10401 and the water guide trough 10403 at the center guide the collected coolant and impurities into the separation box 10401, so that the working fluid is exactly between the pair of magnetic rollers 10405, making the magnetic force more effective. When the rollers 10405 rotate in opposite directions, the adsorbed waste debris comes into contact with one end of the inclined plate 10404. The inclined plate 10404 scrapes the waste debris off the magnetic rollers 10405, allowing the waste debris to smoothly enter the filter basket 10406. The glass fiber filter layer 10412 and the nylon mesh filter layer 10411 in the filter box 10409 are used to filter out small particulate impurities. The glass fiber filter layer 10412 can filter out small particulate impurities, and the nylon mesh filter layer 10411 can intercept larger impurities. Through multi-stage filtration, the cleanliness of the working fluid is further improved, and the blockage of the pipeline is avoided.

[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0034] Please see Figure 1 - Figure 5A heat exchanger 106 is fixedly installed on one side of the bottom of the inner chamber 100. The heat medium inlet of the heat exchanger 106 is connected to the bottom of the inner chamber 10408 through a pipe. A pump 107 is fitted on the heat medium outlet of the heat exchanger 106. The refrigerant inlet pipe and refrigerant storage pipe of the heat exchanger 106 both extend through the inner chamber 100 to the outside. A spray pipe 10202 is installed on one side of the upper end of the cover plate 10201. The bottom end of the spray pipe 10202 is connected to the output end of the pump 107. The heat medium inlet of the heat exchanger 106 on one side of the bottom of the inner chamber 100 is connected to the bottom of the inner chamber 10408 through a pipe, which can introduce filtered coolant into the heat exchanger 106 for cooling. The pump 107 is fitted on the heat medium outlet to provide power for the circulation of the working fluid. The refrigerant inlet pipe and refrigerant storage pipe extend through the inner chamber 100. The heat exchanger 106 extends to the outside, facilitating connection with external cooling equipment to enhance heat exchange, reduce the temperature of the working fluid, and achieve cooling. The spray pipe 10202 on one side of the upper end of the cover plate 10201 is connected to the output end of the pump 107. The pump 107 delivers the cooled working fluid to the spray pipe 10202, which sprays the working fluid onto the processing part of the EDM body 103, providing cooling and lubrication, and improving the processing efficiency and quality of the EDM. A drainage trough is provided on one side of the bottom of the collection tank 10203, and the bottom of the drainage trough is located on one side of the upper end of the hopper 10402, allowing the working fluid and impurities collected in the collection tank 10203 to flow smoothly into the hopper 10402 and enter the filtration mechanism 104 for processing, realizing the recycling of the working fluid and saving resources.

[0035] Specifically, the working principle of this type of EDM machine with cooling function is as follows: During the operation of the EDM machine, the machine body 103 performs EDM processing, and the heat generated needs to be cooled by the working fluid. After completing the cooling task, the working fluid, carrying the processing waste, flows into the collection tank 10203 of the collection mechanism 102. The drainage trough on one side of the bottom of the collection tank 10203 guides the collected working fluid and impurities to the hopper 10402. Under the guidance of the water guide trough 10403 in the center of the hopper 10402, The working fluid accurately enters the separation tank 10401 and is positioned between a pair of magnetic rollers 10405. The servo motor 10414 on one side of the transmission box 10413 starts, driving the gear 10415 connected to its output end to rotate. Because the gears 10415 mesh with each other, the two magnetic rollers 10405 rotate synchronously in opposite directions. During the rotation of the magnetic rollers 10405, ferromagnetic impurities in the working fluid are adsorbed using magnetic force. As the magnetic rollers 10405 rotate, the adsorbed waste debris is separated from the inclined plate 104... 04. With one end in contact, the inclined plate 10404 scrapes the waste debris off the magnetic roller 10405, causing it to fall into the filter basket 10406. After preliminary separation, the working fluid continues to flow downwards and enters the filter box 10409 inside the inner box 10408. The nylon mesh filter layer 10411 in the filter box 10409 first intercepts larger impurities, and the glass fiber filter layer 10412 further filters out small particulate impurities, greatly improving the cleanliness of the working fluid. The working fluid, after multi-stage filtration, flows from the bottom side of the inner box 10408. The working fluid enters the heat exchanger 106 inside the housing 100 through a pipe. In the heat exchanger 106, the working fluid exchanges heat with the externally introduced refrigerant to achieve cooling. The pump 107 provides power for the circulation of the working fluid and delivers the cooled working fluid to the spray pipe 10202 on the cover plate 10201. The spray pipe 10202 sprays the cooled working fluid onto the processing part of the EDM body 103 to cool and lubricate the processing part, thus completing the recycling of the working fluid and ensuring the continuous and efficient operation of the EDM.
