Description

Technical Field

[0001] This invention relates to the technical field of electrical discharge machining equipment, specifically to an electrical discharge machining equipment and method for machining small holes in a porous microchannel heat dissipation mold. Background Technology

[0002] Porous microchannel heat dissipation molds are advanced molds used for heat dissipation of high heat flux density devices. They integrate pores inside the mold. These pores are usually manufactured on a substrate with good thermal conductivity through precision machining technology, which can increase the heat exchange area and enhance the disturbance, thereby achieving heat extraction and uniform temperature distribution.

[0003] Electrical discharge machining (EDM) equipment uses pulsed discharge to instantly melt / vaporize metal at high temperatures, achieving precision machining without cutting force. It is mainly used for machining micro-holes and irregular holes, and is widely used in machining scenarios such as mold cavities, heat dissipation and cooling holes, and pinholes.

[0004] In the process of machining array holes for mold-type workpieces using electrical discharge machining equipment, a fixed chuck is generally used to clamp the workpiece. The XY dual-axis CNC slide table drives the workpiece or machining head to perform planar displacement to achieve the switching of different machining hole positions. The vertical feed motion of the machining head and the planar indexing motion of the workpiece are scheduled and controlled by independent control systems according to a preset timing sequence.

[0005] The above general configuration still has some details that can be optimized in actual production applications: the vertical feed of the processing head, the slide retraction and the workpiece indexing are scheduled by an independent control system according to a preset time sequence. Necessary safety delays need to be reserved between processes. During batch production, these interval times will accumulate significantly, which will reduce the effective operating efficiency of the equipment to a certain extent. In some high-precision processing scenarios, special tooling is also required to assist in positioning, which increases the workload of the production preparation process. Summary of the Invention

[0006] The purpose of this invention is to provide an electrical discharge machining (EDM) device and method for machining small holes in a porous microchannel heat dissipation mold, so as to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, the present invention provides the following technical solution:

[0008] An EDM (Electrical Discharge Machining) device for a porous microchannel heat dissipation mold includes a machining table and a support mounted on the machining table. A guide rod and a spring at the bottom of the guide rod are disposed on the inner side of the support. An electric drive sliding assembly and an EDM device body are slidably mounted on the guide rod at one end of the electric drive sliding assembly. A bidirectional moving mechanism and a bidirectional support mechanism are disposed on the lower inner side of the support. The bidirectional support mechanism cooperates with the electric drive sliding assembly. A press-type control assembly is disposed on the inner side of the support. A positioning adjustment mechanism and a support base are disposed on the upper part of the machining table. A clamping mechanism is rotatably mounted on the top of the support base. An angle adjustment assembly is disposed on the support base. The press-type control assembly, angle adjustment assembly, and bidirectional moving mechanism cooperate remotely via communication.

[0009] The above-described electrical discharge machining (EDM) equipment for a porous microchannel heat dissipation mold includes an electrically controlled slide table slidably mounted on the guide rod and anti-slip drive wheels electrically driven at both ends of the electrically controlled slide table. The outer surfaces of the multiple anti-slip drive wheels are provided with fine toothed grooves for anti-slip purposes. The main body of the EDM equipment is located at one end of the electrically controlled slide table.

[0010] The above-described electrical discharge machining equipment for a porous microchannel heat dissipation mold includes: abutment plates at both the upper and lower ends of the electrically controlled slide, a limiting slide shell at the rear end of the electrically controlled slide, and the electrically controlled slide being slidably mounted on the inner side of the support via the limiting slide shell.

[0011] The above-described electrical discharge machining equipment for a porous microchannel heat dissipation mold: the electrically controlled slide is slidably mounted on the guide rod, and the bottom end of the electrically controlled slide abuts against the spring.

[0012] The above-mentioned electrical discharge machining equipment for a porous microchannel heat dissipation mold: the bidirectional moving mechanism includes a double-rod cylinder disposed on the inner side of the support and connecting plates disposed on both sides of the double-rod cylinder, and a support plate is connected to one end of each of the two connecting plates.

[0013] The above-mentioned electrical discharge machining equipment for a porous microchannel heat dissipation mold includes: the bidirectional support mechanism includes two limiting T-shaped parts disposed at both ends of the inner side of the support; the two support plates are respectively slidably mounted on the two limiting T-shaped parts; one side of each of the two support plates is inlaid with a wear-resistant friction lining; and the two support plates cooperate with the anti-slip drive wheels disposed on both sides of the electrically controlled slide table.

[0014] The above-described electrical discharge machining equipment for a porous microchannel heat dissipation mold includes an adjustment mechanism comprising two sets of guide frames disposed on the top of the machining table and an electric drive slider slidably mounted on the guide frames, a support base disposed between the two electric drive sliders, and a clamping mechanism comprising a chuck rotatably disposed on the top of the support base and a mold body disposed on the chuck.

[0015] The above-described electrical discharge machining equipment for a porous microchannel heat dissipation mold includes an angle adjustment component comprising a stepper motor disposed on one side of the support base and a worm gear disposed on the output shaft of the stepper motor. A worm wheel is engaged on one side of the worm gear, and the worm wheel is sleeved on the bottom of the chuck. A remote control module is disposed on the stepper motor.

[0016] The above-mentioned electrical discharge machining equipment for a porous microchannel heat dissipation mold includes a press-type control component comprising a first switch disposed at the bottom inner side of the support, and a second and a third switch disposed at the top inner side of the support. The first and second switches are used for remote communication to control the extension and retraction of the double-rod cylinder, and the third switch is used for remote communication to control the start of the stepper motor.

[0017] The processing method of an EDM (Electrical Discharge Machining) device for a porous microchannel heat dissipation mold as described above includes the following steps:

[0018] Step 1: First, clamp the mold body to be processed onto the self-rotating chuck. At this time, the two side support plates are in close contact with the anti-slip drive wheels at both ends of the vertical electric control slide. The electric control slide drives the anti-slip drive wheels to roll at a constant speed along the surface of the support plate, which drives the EDM equipment body to slowly feed and perform the processing operation, and compresses the spring.

[0019] Step 2: When the processing is completed, the electric control slide triggers the first switch at the bottom. The first switch communicates remotely to control the extension rods at both ends of the double rod cylinder to extend the telescopic rods, which drive the two side support plates to move outward quickly and completely disengage from the anti-slip drive wheel. At this time, the pre-compressed spring releases its elastic potential energy and pushes the electric control slide vertically upward to reset to the top position.

[0020] Step 3: After the electric control slide reaches the top, it triggers the second and third switches at the top. The second switch remotely communicates to control the retraction of the telescopic rods at both ends of the double rod cylinder, so that the support plates on both sides return to their original positions.

[0021] Step 4: The third switch remotely communicates to control the stepper motor to start. The stepper motor drives the worm gear to rotate through the worm, and the worm gear drives the chuck to rotate, so that the mold body rotates to the preset angle. Then the equipment enters the next processing cycle.

[0022] Compared with the prior art, the beneficial effects of the present invention are:

[0023] The machine utilizes a self-rotating chuck to clamp the workpiece and an electric slide at the top for automatic feeding. Once the electric slide has finished its slow downward machining, a switch is triggered to quickly return the slide to the top. At the same time, a switch is triggered at the top to control the chuck at the bottom to rotate at a certain angle and position it for the next machining step. No additional manual alignment or tooling adjustment is required, enabling fully automatic cyclic machining of circumferential array holes.

[0024] In this invention, the entire processing cycle requires no manual intervention, which improves processing efficiency and accuracy while reducing operational complexity, making it suitable for mold processing that requires precision handling in multiple locations. Attached Figure Description

[0047] In this embodiment, one end of each of the two support plates 11 is provided with a wear-resistant friction lining. This wear-resistant friction lining can cooperate with the anti-slip drive wheel 6 to prevent slippage and increase friction. The limiting T-shaped piece 12 can support the lateral sliding of the support plate 11.

[0048] As a further embodiment of the present invention, the adjustment mechanism includes two sets of guide frames 16 disposed on the top of the processing table 1 and an electric drive slider 17 slidably mounted on the guide frames 16. The support base 18 is disposed between the two electric drive sliders 17. The clamping mechanism includes a chuck 19 rotatably disposed on the top of the support base 18 and a mold body 20 disposed on the chuck 19.

[0049] In this embodiment, an electric drive slider 17 is slidably disposed on each of the two guide frames 16. The electric drive slider 17 can slide along the direction of the guide frame 16. The support base 18 is disposed between the two electric drive sliders 17. The chuck 19 is rotatably disposed above the support base 18.

These parameters can be adjusted as needed to meet the requirements of processing different array hole spacings. The positions of the support base 18 and chuck 19 can be adjusted by the electric drive slider 17, which can position the mold body 20 at different circumferential positions for processing. The worm wheel 24 at the bottom of the chuck 19 meshes with the worm 23 on the side. By starting the stepper motor 21, the worm 23 is driven to rotate, and the worm wheel 24 is driven to rotate, which in turn drives the chuck 19 to deflect, thereby realizing the processing of the circumferential array.

[0054] The processing method of an EDM (Electrical Discharge Machining) device for a porous microchannel heat dissipation mold as described above includes the following steps:

The electric control slide table 5 drives the anti-slip drive wheels 6 to roll at a constant speed along the surface of the support plate 11, which drives the EDM equipment body 25 to slowly feed and perform the processing operation, and compresses the spring 4.

[0056] Step 2: When the processing is completed, the electric control slide 5 triggers the first switch 13 at the bottom. The first switch 13 communicates remotely to control the extension rods at both ends of the double rod cylinder 9, which drives the two side support plates 11 to move outward quickly and completely disengage from the anti-slip drive wheel 6. At this time, the pre-compressed spring 4 releases its elastic potential energy and pushes the electric control slide 5 to return to the top position vertically upward.

[0057] Step 3: After the electric sliding table 5 reaches the top, it triggers the second switch 14 and the third switch 15 at the top. The second switch 14 remotely communicates to control the telescopic rods at both ends of the double rod cylinder 9 to retract, so that the support plates 11 on both sides return to their original positions.

[0058] Step 4: The third switch 15 remotely communicates to control the start of the stepper motor 21. The stepper motor 21 drives the worm wheel 24 to rotate through the worm 23. The worm wheel 24 drives the chuck 19 to rotate, so that the mold body 20 rotates to the preset angle. Then the equipment enters the next processing cycle.

[0059] The above embodiments are exemplary and not restrictive. Therefore, any technical solutions that can be implemented in other specific forms without departing from the spirit or basic characteristics of the present invention are included within the scope of the present invention.
