Description

Technical Field

[0001] The present invention relates to the technical field of electric discharge machining, and particularly to a die core processing device. Background Art

[0002] Electric discharge machining is a new processing technology that utilizes electrical energy and thermal energy. The difference between electric discharge machining and general cutting machining is that during electric discharge machining, the tool does not contact the workpiece. Instead, pulsed spark discharges continuously occur between the tool and the workpiece. By using the locally and instantaneously high temperature generated during the discharge to gradually erode the metal material, since visible sparks are generated during the discharge process, it is called electric discharge machining. Electric discharge machining equipment can be used for the forming machining of die core cavities.

[0003] In the prior art, during the electric discharge machining process, the workpiece needs to be immersed in the working fluid. However, during the electro-erosion forming process of the workpiece, the vaporized workpiece material condenses into particulate impurities in the working fluid. If these particles cannot be cleaned in time, it will affect the quality of electric discharge machining. Therefore, during the electric discharge machining process, it is often necessary to stop the machine to clean the impurity particles in the working fluid, thus affecting the machining efficiency of the workpiece. Summary of the Invention

[0004] The present application provides a die core processing device, which can automatically remove impurities from the working fluid while ensuring the normal progress of machining, reduce the downtime waiting time, and improve the machining efficiency of the workpiece.

[0005] A die core processing device provided by the present application adopts the following technical solutions: A die core processing device includes a workbench, a working fluid tank, a servo adjustment mechanism, and a filter tank; the working fluid tank is installed on the workbench, and a contact electrode is provided on the bottom wall of the working fluid tank; a fixture for clamping the workpiece is provided on the top surface of the contact electrode; the servo adjustment mechanism is arranged on the top surface of the workbench, and a tool electrode is arranged on the servo adjustment mechanism; a pulse power supply is arranged on the top surface of the workbench; the positive and negative electrodes of the pulse power supply are electrically connected to the tool electrode and the contact electrode respectively; the filter tank is arranged at the bottom of the workbench, and a mounting plate is provided on the inner wall of the filter tank; a first filter screen is arranged on the mounting plate; a communication pipe for connecting the working fluid tank and the filter tank is provided on the inner wall at the top of the filter tank; a spraying mechanism is arranged in the working fluid tank; the spraying mechanism can transport the working fluid in the filter tank to the working fluid tank.

[0006] By adopting the above technical solution, the workpiece is placed on the top of the contact electrode and clamped and fixed by a fixture. Working fluid is added into the working fluid tank to immerse the workpiece in the working fluid. When the servo adjustment mechanism drives the tool electrode to move for electric discharge machining of the workpiece, a large amount of electro-erosion products will accumulate in the working fluid, which affects the machining quality. At this time, the working fluid and electro-erosion products in the working fluid tank can be transported to the filter box through the connecting pipe, and the working fluid is filtered by the first filter screen to separate the electro-erosion products in the working fluid. During this process, the working fluid in the filter box is continuously transported to the working fluid tank by the spraying mechanism to ensure the normal progress of machining, realizing the automatic impurity removal of the working fluid and improving the working efficiency.

[0007] Preferably, the spraying mechanism includes an annular pipe and a pump body; the annular pipe is fixedly connected to the bottom wall of the working fluid tank, and a plurality of spray pipes are arranged on the outer wall of the annular pipe; the pump body is installed on the top surface of the workbench, the input end of the pump body is fixedly connected with a water inlet pipe communicated with the filter box, and the output end of the pump body is fixedly connected with a water outlet pipe communicated with the annular pipe.

[0008] By adopting the above technical solution, when the pump body is started, the working fluid in the filter box can be pumped out and transported into the annular pipe. When the working fluid is sprayed out from the spray pipe, it not only realizes the replenishment of the working fluid in the working fluid tank, but also can wash the workpiece, reducing the possibility of the discharge gap being contaminated.

[0009] Preferably, the mounting plate is inclined; a first opening is formed on the inner side wall of the filter box near the lower end of the mounting plate, and a guide rod is fixedly connected to the top inner wall of the filter box near the upper end of the mounting plate; an impact block is slidably sleeved on the outer wall of the bottom end of the guide rod; the bottom end of the impact block is in contact with the top surface of the mounting plate, and the top surface of the impact block is connected with the top inner wall of the filter box through a first spring; a driving member is arranged on the filter box to reciprocally drive the impact block to move upward.

[0010] By adopting the above technical solution, during the process of filtering the working fluid by the first filter screen, the driving member can be used to drive the impact block to move upward away from the mounting plate and compress the first spring. When the driving member loses contact with the impact block, the impact block will move downward under the elastic force of the first spring to impact the mounting plate, causing the mounting plate and the first filter screen to vibrate, prompting the electro-erosion products accumulated on the first filter screen to slide and be discharged out of the filter box through the first opening, reducing the possibility of the mesh holes of the first filter screen being blocked by electro-erosion products and ensuring the filtering effect of the first filter screen.

[0011] Preferably, the driving member includes a motor and a connecting plate; the motor is installed on the outer wall of the filter box, and the output end of the motor is coaxially fixedly connected with a driving shaft extending into the filter box; a first cam is coaxially fixedly connected to the end of the driving shaft away from the motor; the connecting plate is connected to the top surface of the impact block through a connecting rod, the connecting plate is located above the first cam, and the bottom surface of the connecting plate is in an arc shape that can be in contact and cooperate with the first cam.

[0012] By adopting the above technical solution, when the starting motor drives the drive shaft to rotate, the drive shaft will drive the first cam to rotate. After the first cam contacts the arc surface at the bottom of the connecting plate, the first cam will squeeze the connecting plate to drive the impact block to move upward. After the first cam loses contact with the connecting plate, the connecting plate and the impact block will move downward and reset, so as to realize that the impact block can move up and down reciprocally to impact the mounting plate during the rotation of the first cam.

[0013] Preferably, a material receiving box is detachably installed on the outer wall of the filter box provided with the first opening; a second opening matching the first opening is provided at the position of the material receiving box corresponding to the first opening.

[0014] By adopting the above technical solution, the material receiving box is provided for collecting the sundries slipping from the surface of the first filter screen, which is convenient for the staff to uniformly process the collected electro-erosion products.

[0015] Preferably, a conical plate located at the bottom of the connecting pipe is arranged on the top of the first filter screen; the bottom surface of the conical plate is connected to the side wall of the filter box through a support rod, and a plurality of diversion grooves are arranged on the top surface of the conical plate.

[0016] By adopting the above technical solution, the conical plate can divert the working fluid flowing into the filter box through the connecting pipe, so that the working fluid flows down in multiple strands along the diversion grooves, reducing the impact effect of the working fluid on the first filter screen and reducing the possibility of damage to the first filter screen due to large impact.

[0017] Preferably, an air vent pipe is fixedly connected to the bottom surface of the conical plate; a plurality of air jet nozzles are horizontally arranged on the outer wall of the air vent pipe; a blowing mechanism capable of reciprocally supplying air into the air vent pipe is arranged on the outer wall of the filter box.

[0018] By adopting the above technical solution, when the working fluid falls into the filter box through the connecting pipe for filtration treatment, the blowing mechanism can blow air into the air vent pipe and blow it out through the air jet nozzles. The gas blown out through the air jet nozzles cools the working fluid flowing down from the surface of the conical plate by blowing, promoting the dissipation of the heat of the working fluid, so that the working fluid can be recycled.

[0019] Preferably, the blowing mechanism includes a concave shell, an air bag and a second cam; the concave shell is fixedly connected to the outer wall of the filter box where the motor is located. The concave shell is located at the bottom of the motor. A slider is slidably connected to the inner wall of the concave shell; the bottom surface of the slider is connected to the bottom wall of the concave shell through a second spring; the air bag is arranged in the concave shell. The air bag is located at the bottom of the slider and contacts the bottom surface of the slider. An air delivery pipe communicating with the air vent pipe is connected to the air bag; the second cam is fixedly connected to the outer wall of the end of the drive shaft close to the motor. The second cam is located on the top of the slider; the top surface of the slider is in an arc shape that can contact and cooperate with the second cam.

[0020] By adopting the above technical solution, during the process of the first motor driving the drive shaft to rotate, the second cam will contact the slider. When the slider is squeezed by the second cam and moves downward, the slider will compress the second spring and squeeze the airbag, prompting the gas inside the airbag to enter the ventilation pipe through the air delivery pipe, so that the jet nozzle can blow gas to cool the working fluid by blowing. When the second cam loses contact with the slider, the slider resets under the elastic force of the second spring, and the airbag returns air, so as to realize that the airbag reciprocally conveys gas into the ventilation pipe during the process of the second cam reciprocally squeezing the slider.

[0021] Preferably, a heat dissipation port is provided on the inner wall of the top end of the filter box; a second filter screen is provided on the inner wall of the heat dissipation port.

[0022] By adopting the above technical solution, the setting of the heat dissipation port facilitates the dissipation of heat in the filter box, and the setting of the second filter screen is used to block dust and impurities, reducing the possibility of dust and impurities in the external environment entering the filter box.

[0023] Preferably, a semiconductor refrigeration sheet is provided on the outer wall of the filter box.

[0024] By adopting the above technical solution, the semiconductor refrigeration sheet provided on the outer wall of the filter box can be used for cooling and dissipating heat of the working fluid, prompting the working fluid to have a better cooling effect on the workpiece and the electrode during the recycling process.

[0025] In summary, the present application has the following beneficial effects: 1. When there are a large number of electro-erosion products accumulated in the working fluid, open the valve to convey the working fluid to the filter box, and filter and remove impurities from the working fluid through the first filter screen. During this process, the spraying mechanism continuously conveys the working fluid in the filter box to the working fluid tank, automatically removing impurities from the working fluid while ensuring the normal progress of electrical discharge machining, reducing the downtime waiting time, and improving the workpiece processing efficiency; 2. When filtering the working fluid, the driving member drives the impact block to move upward away from the mounting plate and compress the first spring. When the driving member loses contact with the impact block, the impact block will move downward under the elastic force of the first spring and impact the mounting plate, prompting the mounting plate and the first filter screen to vibrate, so that the electro-erosion products accumulated on the first filter screen slide into the receiving box for collection, ensuring the filtering effect of the first filter screen; 3. The conical plate can divide the working fluid flowing into the filter box through the connecting pipe, prompting the working fluid to flow down in multiple strands along the diversion groove, reducing the impact effect of the working fluid on the first filter screen, and reducing the possibility of the first filter screen being damaged by a large impact.

Detailed implementation manners

[0028] The present invention will be further described in detail below with reference to the accompanying drawings. The same components are denoted by the same reference numerals. It should be noted that the terms "front", "rear", "left", "right", "upper", "lower", "bottom surface" and "top surface" used in the following description refer to the directions in the drawings, and the terms "inner" and "outer" respectively refer to the directions towards or away from the geometric center of a specific component.

[0029] The present invention discloses a die core processing device, as Figure 1 and Figure 2As shown in the figure, it includes a workbench 1, a working fluid tank 2, a servo adjustment mechanism 3, a filter box 4, a pulse power supply 5 and a spraying mechanism 6; the working fluid tank 2 is installed on the top surface of the workbench 1, and a contact electrode 21 is provided on the bottom wall of the working fluid tank 2, and a fixture 22 for clamping the workpiece is provided on the top surface of the contact electrode 21; the servo adjustment mechanism 3 is arranged on the top surface of the workbench 1, and a tool electrode 31 is arranged on the servo adjustment mechanism 3. The servo adjustment mechanism 3 is a prior art and will not be elaborated here. The servo adjustment mechanism 3 can adjust the position of the tool electrode 31. The pulse power supply 5 is arranged on the top surface of the workbench 1, and the positive and negative electrodes of the pulse power supply 5 are electrically connected to the tool electrode 31 and the contact electrode 21 respectively. The filter box 4 is arranged at the bottom of the workbench 1. The filter box 4 can filter the working fluid. A connecting pipe 43 fixedly connected to the bottom wall of the working fluid tank 2 is fixedly connected to the top end of the filter box 4, and a valve is arranged on the connecting pipe 43. The spraying mechanism 6 is arranged in the working fluid tank 2, and the spraying mechanism 6 can transport the working fluid in the filter box 4 into the working fluid tank 2.

[0030] Place the workpiece on the top of the contact electrode 21 and clamp and fix it through the fixture 22. Add working fluid into the working fluid tank 2 to submerge the workpiece. When the servo adjustment mechanism 3 drives the tool electrode 31 to move for electrical discharge machining of the workpiece, a large amount of electro-erosion products will accumulate in the working fluid. At this time, the valve can be opened to transport the working fluid into the filter box 4 for filtration. During this process, the spraying mechanism 6 can continuously transport the working fluid in the filter box 4 into the working fluid tank 2 to automatically remove impurities from the working fluid while ensuring the normal progress of machining.

[0031] As Figure 1 and Figure 2 shown in the figure, the spraying mechanism 6 includes a ring pipe 61, a pump body 62, a water inlet pipe 621 and a water outlet pipe 622. The ring pipe 61 is fixedly connected to the bottom wall of the working fluid tank 2. A plurality of spray pipes 611 are arranged on the outer wall of the ring pipe 61. The spray pipes 611 are universal joint pipes that can adjust the water outlet direction. The pump body 62 is installed on the top surface of the workbench 1. One end of the water inlet pipe 621 is fixedly connected to the input end of the pump body 62, and the other end is fixedly connected to the side wall near the bottom end of the filter box 4 and communicates with the filter box 4. One end of the water outlet pipe 622 is fixedly connected to the output end of the pump body 62, and the other end is fixedly connected to the side wall of the ring pipe 61 and communicates with the ring pipe 61.

[0032] When transporting the working fluid, start the pump body 62. The working fluid is transported into the ring pipe 61 through the water inlet pipe 621 and the water outlet pipe 622, and then sprayed into the working fluid tank 2 through the spray pipes 611, so as to conveniently realize the replenishment of the working fluid in the working fluid tank 2.

[0033] As Figure 1 and Figure 3 shown in the figure, an inclined mounting plate 41 is fixedly connected to the inner side wall near the top end of the filter box 4, and a first filter screen 42 for filtering the working fluid is arranged on the mounting plate 41.

[0034] After the working fluid in the working fluid tank 2 enters the filtration box 4 through the connecting pipe 43, the first filter screen 42 provided on the mounting plate 41 can filter the working fluid to separate the electric erosion products doped in the working fluid.

[0035] As Figure 1 、 Figure 3 and Figure 4 As shown in The filtration box 4 is provided with a first opening 44 on the side wall near the lower end of the mounting plate 41. A receiving box 45 is detachably installed on the outer wall of the filtration box 4 where the first opening 44 is located. The receiving box 45 is provided with a second opening 451 corresponding to the first opening 44 and cooperating with the first opening 44;

[0036] When the first filter screen 42 filters the working fluid, the motor 731 can be started to drive the drive shaft 733 and the first cam 734 to rotate. After the first cam 734 contacts the arc surface at the bottom end of the connecting plate 732, the first cam 734 will squeeze the connecting plate 732 to drive the impact block 71 to move upward. When the first cam 734 loses contact with the connecting plate 732, the connecting plate 732 and the impact block 71 will move downward to reset. Thus, during the rotation of the first cam 734, the impact block 71 repeatedly impacts the mounting plate 41, causing the mounting plate 41 and the first filter screen 42 to vibrate, prompting the electric erosion products accumulated on the first filter screen 42 to slide into the receiving box 45 for collection, reducing the possibility of the mesh holes of the first filter screen 42 being blocked.

[0037] As Figure 3 and Figure 5 As shown in

[0038] When the working fluid enters the filter box 4 through the connecting pipe 43 for filtration, the conical plate 46 can divert the falling working fluid, causing the working fluid to fall onto the surface of the first filter screen 42 in multiple strands along the diversion grooves 461, reducing the impact effect of the concentrated fall of the working fluid on the first filter screen 42.

[0039] As Figure 1 , Figure 3 and Figure 5 shown, a plurality of heat dissipation openings 48 are formed in the inner wall of the top end of the filter box 4, and a second filter screen 481 is provided on the inner wall of each heat dissipation opening 48. A ventilation pipe 47 is fixedly connected to the bottom surface of the conical plate 46, and a plurality of horizontally arranged air jet nozzles 471 are provided on the outer wall of the ventilation pipe 47. A blowing mechanism 8 capable of reciprocally supplying air into the ventilation pipe 47 is provided on the outer wall of the filter box 4.

[0040] When the working fluid falls into the filter box 4 for filtration, the blowing mechanism 8 can supply air into the ventilation pipe 47 and then spray it out through the air jet nozzles 471. The gas sprayed through the air jet nozzles 471 blows and cools the working fluid flowing down from the surface of the conical plate 46, promoting the heat of the working fluid to dissipate through the heat dissipation openings 48, so that the working fluid can be recycled.

[0041] As Figure 1 , Figure 5 and Figure 6 shown, the blowing mechanism 8 includes a concave shell 81, an air bag 82, a second cam 83 and a slider 84. The concave shell 81 is vertically fixedly connected to the outer wall of the filter box 4. The concave shell 81 is located at the bottom of the first motor 731 with its opening facing upwards. The slider 84 is slidably connected to the inner wall of the concave shell 81. The bottom surface of the concave shell 81 is connected to the inner wall of the bottom end of the concave shell 81 through a second spring 85. The air bag 82 is arranged in the concave shell 81. The air bag 82 is located at the bottom wall of the slider 84 and contacts the bottom surface of the slider 84. An air delivery pipe 86 is connected to the air bag 82. The end of the air delivery pipe 86 far from the air bag 82 is fixedly connected to the side wall of the ventilation pipe 47 and communicates with the ventilation pipe 47. The second cam 83 is fixedly connected to the outer wall of the end of the driving shaft 733 close to the first motor 731. The second cam 83 is located on the top of the slider 84. The top surface of the slider 84 is in an arc shape that can contact and cooperate with the second cam 83.

[0042] When the first motor 731 drives the driving shaft 733 to rotate, the second cam 83 will contact the slider 84. When the slider 84 is pushed down by the second cam 83, the slider 84 will compress the second spring 85 and squeeze the air bag 82, causing the gas inside the air bag 82 to enter the ventilation pipe 47 through the air delivery pipe 86, so that the air jet nozzles 471 can spray gas to blow and cool the working fluid. When the second cam 83 loses contact with the slider 84, the slider 84 resets under the elastic force of the second spring 85, and the air bag 82 takes in air, so as to realize that the air bag 82 can reciprocally supply gas into the ventilation pipe 47 during the process of the second cam 83 reciprocally squeezing the slider 84.

[0043] As shown Figure 1 in FIG. 4, a plurality of semiconductor refrigeration chips 49 are provided on the outer wall of the filter box 4 near the bottom end.

[0044] The setting of the semiconductor refrigeration chips 49 can further cool and dissipate the heat of the working fluid in the filter box 4, so that the heat of the working fluid can be quickly dissipated.

[0045] Working principle: Place the workpiece on the top surface of the contact electrode 21 and clamp the workpiece by the fixture 22. Add the working fluid into the working fluid tank 2 to submerge the workpiece. Then drive the tool electrode 31 to move by the servo adjustment mechanism 3 to perform electric discharge machining on the workpiece. The electro-erosion products generated during the electric discharge machining will remain in the working fluid. When there are more electro-erosion products accumulated in the working fluid tank 2, open the valve on the connecting pipe 43 to transport the working fluid in the working fluid tank 2 into the filter box 4. Use the first filter screen 42 to filter the working fluid and separate the electro-erosion products in the working fluid. While transporting the working fluid into the filter box 4 for filtration, start the pump body 62 to pump out the filtered working fluid in the filter box 4 and transport it into the annular pipe 61, and the working fluid is sprayed into the working fluid tank 2 by the water spraying pipe 611 to achieve the replenishment of the working fluid in the working fluid tank 2 and ensure the normal progress of the electric discharge machining of the workpiece; When the working fluid in the working fluid tank 2 enters the filter box 4 through the connecting pipe 43 for filtration, the conical plate 46 can shunt the falling working fluid, so that the working fluid flows onto the surface of the first filter screen 42 in multiple strands along the shunt groove 461, thereby reducing the impact effect of the concentrated falling of the working fluid on the first filter screen 42 and playing a protective role for the first filter screen 42; During the process of the first filter screen 42 filtering the working fluid, the motor 731 can be started to drive the drive shaft 733 and the first cam 734 to rotate. When the first cam 734 contacts the arc surface at the bottom end of the connecting plate 732, the first cam 734 will squeeze the connecting plate 732 to drive the impact block 71 to move upward. When the first cam 734 loses contact with the connecting plate 732, the connecting plate 732 and the impact block 71 will move downward to reset. Thus, the first cam 734 drives the impact block 71 to repeatedly impact the top surface of the mounting plate 41 during rotation, causing the mounting plate 41 and the first filter screen 42 to vibrate, so that the electro-erosion products accumulated on the first filter screen 42 slide and are discharged out of the filter box 4 through the first opening 44, reducing the possibility of the mesh holes of the first filter screen 42 being blocked by electro-erosion products and ensuring the filtering effect of the first filter screen 42.

[0046] The above are all the preferred embodiments of the present application, and the protection scope of the present application is not limited accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application should be covered within the protection scope of the present application.
