Description

Technical Field

[0001] This utility model belongs to the field of graphite pad processing technology, and specifically relates to a leveling device for graphite pad processing. Background Technology

[0002] Graphite pads are widely used in sealing, heat conduction, and electrical conduction applications due to their excellent high temperature resistance, corrosion resistance, electrical and thermal conductivity, and self-lubricating properties. In the processing of graphite pads (especially flexible graphite pads), leveling is a key pre-processing step. Flexible graphite sheets / rolls are prone to warping, deformation, or local dents during transportation and storage. If they are not leveled before laser cutting or stamping, it will lead to inaccurate positioning, uneven cutting depth, large dimensional errors, and even scrap.

[0003] Existing leveling devices for graphite pad processing place warped graphite plates inside a leveling groove and move them back and forth on rollers, repeatedly bending the material in opposite directions until the internal stress exceeds the yield limit, causing plastic deformation and eliminating the original internal stress to achieve the purpose of leveling. However, in actual use, due to the significant differences in thickness and material between the flexible graphite plates to be processed, the pressure may be mismatched with the flexible graphite plates during the leveling process. This may result in excessive pressure causing material damage or insufficient pressure leading to poor leveling effect. Utility Model Content

[0004] In view of this, this utility model addresses the shortcomings of the prior art by providing a leveling device for graphite pad processing. By adjusting the horizontal distance between the leveling wheels on both sides, it can easily adapt to flexible graphite rolls of different widths. The scissor brace structure, composed of a drive block, connecting rod, and driven block, can precisely control the descent height of the leveling cylinder and leveling wheels as well as the pressure applied to the material. This adjustable width and controllable pressure design allows the equipment to flexibly handle flexible graphite plates of different thicknesses and materials, achieving personalized and precise leveling, and avoiding material damage due to excessive pressure or poor leveling effect due to insufficient pressure.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: a leveling device for graphite pad processing, including a processing table, a support frame fixedly installed on the upper surface of the processing table, and multiple sliding grooves evenly distributed around the vertical center of the support frame fixedly installed on the lower side of the support frame, with a slider slidably installed on each sliding groove, and a movable frame fixedly installed between the sliders; a leveling groove fixedly installed on the upper surface of the processing table; multiple door panels rotatably installed on the front side of the processing table, and multiple support legs installed on the lower surface of the processing table; A movable seat is fixedly installed on the lower side of the movable frame. Two sliding seats are symmetrically distributed around the vertical center of the movable seat. A mounting plate is fixedly installed at the bottom of each sliding seat. A U-shaped seat is fixedly installed in the middle of the lower surface of each mounting plate. A leveling cylinder is rotatably installed inside each U-shaped seat. Two L-shaped seats are symmetrically distributed around the vertical center of each mounting plate. A leveling wheel is rotatably installed inside each L-shaped seat. A sliding rod is fixedly installed in the middle of each leveling wheel. The sliding rod is slidably connected to the adjacent leveling cylinder.

[0006] As a further improvement of this utility model, multiple positioning holes are provided on both sides of the upper surface of the mounting plate, and positioning bolts are threadedly connected between the positioning holes and the adjacent L-shaped seats; a bidirectional lead screw is rotatably provided inside the movable seat, and the sliding seats are threadedly connected to the bidirectional lead screw; a servo motor is provided on the outside of the movable seat, and the output shaft of the servo motor is fixed to the bidirectional lead screw through a coupling.

[0007] As a further improvement of this utility model, two sliders are slidably arranged on the upper side of the slide groove, and a drive seat is fixedly arranged between the two sliders. Two guide grooves are opened on the lower surface of the drive seat, symmetrically distributed around the vertical center of the drive seat. Two guide rails are fixedly arranged inside the drive seat, symmetrically distributed around the vertical center of the drive seat. Two drive blocks are slidably arranged between the guide rails and the adjacent guide grooves. Two slide rails are fixedly arranged inside the movable frame, symmetrically distributed around the vertical center of the movable frame. Two driven blocks are slidably arranged on each slide rail. A connecting rod is rotatably arranged on each driven block. The end of the connecting rod away from the driven block is rotatably connected to the adjacent drive block. The middle part of the connecting rod is rotatably connected to each other through a rotating rod. A two-way lead screw is rotatably arranged in the middle of the drive seat. A connecting rod is fixedly arranged between two adjacent drive blocks. The connecting rod is threadedly connected to the two-way lead screw. A servo motor is arranged on the outer side of the drive seat. The output shaft of the servo motor is fixed to the two-way lead screw through a coupling.

[0008] As a further improvement of this utility model, two hydraulic rods are fixedly installed on the upper surface of the support frame, which are symmetrically distributed around the vertical center of the support frame. The telescopic ends of the hydraulic rods are connected and fixed to the drive seat. A hydraulic pump is installed on the upper surface of the support frame, and the oil inlet and outlet of the hydraulic rods are connected to the hydraulic pump.

[0009] Compared with the prior art, the beneficial effects of this utility model are as follows: Firstly, it can achieve precise control with adjustable parameters. By sliding the L-shaped seat, the horizontal distance between the two leveling wheels can be manually adjusted, easily adapting to flexible graphite rolls of different widths. More importantly, the servo motor drives the bidirectional lead screw, and through the scissor brace structure composed of the drive block, connecting rod, and driven block, it can precisely control the overall descent height of the leveling cylinder and leveling wheels and the pressure applied to the material. This adjustable width and controllable pressure design allows the equipment to flexibly handle flexible graphite plates of different thicknesses and materials, achieving personalized fine leveling and avoiding material damage due to excessive pressure or poor leveling effect due to insufficient pressure.

[0010] Secondly, by controlling the leveling cylinder and leveling wheel to repeatedly and in reverse bend the material, this process stretches the shorter (compressed) "fibers" inside the material, eventually making all the "fibers" of similar length, thus achieving the purpose of leveling. More importantly, this repeated bending causes the stress in the material to exceed the yield limit, resulting in plastic deformation, which can completely eliminate the original internal stress. This method of eliminating stress at its source can significantly reduce the risk of deformation and springback of the material after leveling, ensuring the long-term stability of the leveling effect. This is crucial for the subsequent manufacturing of high-performance fuel cell bipolar plates. Attached Figure Description

The sliding rod 208 is slidably connected to the adjacent leveling cylinder 205. Multiple positioning holes 209 are opened on both sides of the upper surface of the mounting plate 203. Positioning bolts are threadedly connected between the positioning holes 209 and the adjacent L-shaped seats 206.

[0016] like Figure 2 , 4As shown, a bidirectional lead screw 210 is rotatably mounted inside the movable seat 201, and the sliding seats 202 are all threadedly connected to the bidirectional lead screw 210. A servo motor 211 is mounted on the outside of the movable seat 201, and the output shaft of the servo motor 211 is fixed to the bidirectional lead screw 210 by a coupling.

[0017] like Figure 2 , 3 As shown, two sliders 303 are slidably mounted on the upper side of the slide groove 106. A drive seat 304 is fixedly mounted between the two sliders 303. Two guide grooves 305 are symmetrically distributed about the vertical center of the drive seat 304 on the lower surface of the drive seat 304. Two guide rails 306 are symmetrically distributed about the vertical center of the drive seat 304 and fixedly mounted inside the drive seat 304. Two drive blocks 307 are slidably mounted between the guide rails 306 and the adjacent guide grooves 305. Two slide rails 301 are symmetrically distributed about the vertical center of the movable frame 108 and fixedly mounted inside the movable frame 108. Two drive blocks 307 are slidably mounted on the slide rails 301. There are two driven blocks 302, each with a connecting rod 308 rotatably mounted on it. The end of the connecting rod 308 away from the driven block 302 is rotatably connected to the adjacent drive block 307. The middle parts of the connecting rods 308 are rotatably connected by a rotating rod. A double-acting lead screw 309 is rotatably mounted in the middle of the drive seat 304. A connecting rod 310 is fixed between each of the two adjacent drive blocks 307. The connecting rod 310 is threadedly connected to the double-acting lead screw 309. A servo motor 311 is mounted on the outside of the drive seat 304. The output shaft of the servo motor 311 is fixed to the double-acting lead screw 309 by a coupling.

[0018] like Figure 1 , 4 As shown, two hydraulic rods 109 are fixedly installed on the upper surface of the support frame 105, which are symmetrically distributed around the vertical center of the support frame 105. The telescopic ends of the hydraulic rods 109 are connected and fixed to the drive seat 304. A hydraulic pump 110 is installed on the upper surface of the support frame 105. The oil inlet and oil outlet of the hydraulic rods 109 are both connected to the hydraulic pump 110.

[0019] According to another embodiment of the present invention, such as Figure 1 , 2 As shown, the front side of the processing table 101 is provided with multiple door panels 102, and the lower surface of the processing table 101 is provided with multiple support legs 103.

[0020] When in use, place the flexible graphite plate / roll inside the leveling groove 104; Then, the hydraulic pump 110 is controlled to run, thereby causing the hydraulic pump 110 to control the extension and retraction end of the hydraulic rod 109 through the oil inlet and oil outlet of the hydraulic rod 109 to drive the drive seat 304 to move downward, so that the drive seat 304 moves downward to a suitable height. According to the width of the flexible graphite plate / roll, slide the L-shaped seats 206 on both sides of each mounting plate 203, thereby causing the L-shaped seats 206 on both sides to move towards each other or away from each other, thereby causing the leveling wheels 207 on both sides to move towards each other or away from each other. At this time, the sliding rod 208 slides directly with the leveling cylinder 205, so that the leveling wheels 207 on both sides of each leveling cylinder 205 can cooperate with the leveling cylinder 205 so that the distance between the leveling wheels 207 on both sides of the leveling cylinder 205 can adapt to the width of the flexible graphite plate / roll to be leveled. Then, the servo motor 311 is controlled to run, which in turn drives the bidirectional lead screw 309 connected to it to rotate. Then, through the threaded relationship between the bidirectional lead screw 309 and the connecting rod 310, the connecting rods 310 on both sides move closer together, which in turn drives the driving blocks 307 on both sides to move closer together. During the movement of the driving block 307: the driving block 307 rotates with the connecting rod 308, the connecting rod 308 rotates with the driven block 302, the middle part of the connecting rod 308 rotates, and the driven blocks 302 on both sides move closer together. Since the scissor brace structure that can be formed between the driving block 307, the connecting rod 308 and the driven block 302 drives the movable frame 108 where the driven block 302 is located to move downward, the movable frame 108 drives the leveling cylinder 205 and the leveling wheel 207 to contact the flexible graphite plate / roll material placed inside the leveling groove 104. Then, the servo motor 211 is controlled to run, causing the output shaft of the servo motor 211 to drive the bidirectional lead screw 210 connected to it to rotate. In turn, through the threaded relationship between the bidirectional lead screw 210 and the sliding seat 202, the sliding seats 202 on both sides are driven to move towards each other or away from each other. This in turn drives the mounting plates 203 on both sides to move towards each other or away from each other, and drives the leveling cylinders 205 and leveling wheels 207 on both sides to move towards each other or away from each other. This causes the leveling cylinders 205 and leveling wheels 207 on both sides to move back and forth horizontally, causing the flexible graphite plate / roll material placed inside the leveling groove 104 to bend repeatedly and in opposite directions, causing the internal stress to exceed the yield limit and undergo plastic deformation, thereby eliminating the original internal stress and achieving the purpose of leveling.

[0021] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Any other modifications or equivalent substitutions made by those skilled in the art to the technical solution of this utility model, as long as they do not depart from the spirit and scope of the technical solution of this utility model, should be covered within the scope of the claims of this utility model.
