Description

Technical Field

[0001] This utility model relates to the field of SMC sheet manufacturing technology, and more specifically, to an edge cutting device based on SMC sheet manufacturing. Background Technology

[0002] SMC (Sheet Molding Compound), as a fiber-reinforced composite material, has been widely used in various fields such as automotive manufacturing, electrical equipment, and building materials due to its excellent mechanical properties, corrosion resistance, insulation properties, and ease of molding. In the production and subsequent processing of SMC sheets, edge cutting is a crucial step. Its purpose is to remove burrs and flash generated during the sheet molding process, or to cut the sheet to precise dimensions that meet the requirements of subsequent assembly and use. The cutting accuracy and cut quality directly affect the assembly accuracy, appearance quality, and performance of the final product.

[0003] To achieve stable cutting of SMC sheets, edge cutting devices are typically equipped with clamping mechanisms to hold the sheet in place during the cutting process, preventing displacement or vibration caused by the impact and friction of the cutting tool, thus ensuring cutting accuracy. Currently, most mainstream clamping devices in the industry employ a structure that clamps both ends of the sheet. This structure uses clamping components at both ends along the length or width of the sheet, employing cylinder-driven clamping plates or hydraulically driven clamping blocks to apply pressure to the ends of the sheet for fixation. However, this "point-to-surface" force transmission structure with clamping at both ends is prone to force loss due to uneven contact and frictional fluctuations. Excessive clamping force can cause significant extrusion deformation at the clamping points of the SMC sheet. Because SMC sheets contain resin matrix and glass fiber, their overall compressive strength is limited. Excessive compression can cause physical damage such as dents and cracks at the ends of the sheet, and may also disrupt the internal fiber arrangement, affecting the uniformity of the mechanical properties of the sheet after cutting. Simultaneously, excessive clamping force can put the sheet under excessive tension, and when the cutting tool contacts the sheet during cutting, the release of internal stress may lead to problems such as skewing and chipping of the cut. On the other hand, if the clamping force is too small, it cannot provide sufficient restraint for the sheet. Under the action of a high-speed rotating cutting tool, the sheet is prone to lateral movement or vertical vibration, causing the cut position to deviate from the preset trajectory, making it difficult to guarantee cutting dimensional accuracy. In addition, vibration can roughen the cut surface, producing a large number of burrs, increasing the workload and cost of subsequent grinding processes, and may even affect the safety of subsequent assembly and use due to incomplete burr removal. Therefore, improvements are needed. Utility Model Content

A horizontal plate is welded to the right side of the bottom end of the vertical plate. A third servo motor is bolted to the inner side of the front end of the horizontal plate. The output end of the third servo motor extends through to the front side of the horizontal plate and is bolted with a grinding wheel.

[0007] As a preferred embodiment of this utility model, a first servo motor is bolted on the left side of the platform, and the output end of the first servo motor extends into the interior of the transverse groove and is bolted to the left end of the bidirectional screw.

[0008] As a preferred embodiment of this utility model, columns are welded to the top of both ends of the rectangular plate, a top plate is bolted to the top of the columns, a cylinder is bolted to the top of the front end of the top plate, and the output end of the cylinder extends through to the bottom of the top plate and is bolted to a fixing plate.

[0009] As a preferred embodiment of this utility model, a control board is bolted to the front side of the platform, and the control board is electrically connected to the first servo motor, the cylinder, the linear module, the second servo motor, and the third servo motor.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: 1.

[0014] 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.

[0015] like Figures 1 to 5 As shown, this utility model provides an edge cutting device based on SMC sheet manufacturing, including a worktable 1, the worktable 1 including a table body 11, a clamping mechanism 2 and a cutting mechanism 3 arranged on the upper part of the table body 11, a horizontal groove 13 and a cutting groove 14 opened on the upper side of the table body 11, the clamping mechanism 2 including a movable block 201 slidably connected inside the horizontal groove 13, a rectangular plate 202 welded above the movable block 201, a rectangular groove 203 opened inside the rectangular plate 202, and a movable part slidably installed inside the rectangular groove 203. The movable plate 204 has a connecting plate 205 welded to its front end, which extends to the outside of the rectangular plate 202. The front end of the connecting plate 205 has a clamping plate 206 welded to it. A pressure sensor 207 is bolted to the bottom of the rectangular groove 203. A telescopic spring 208 is elastically installed between the inner side of the pressure sensor 207 and the inner side of the movable plate 204. A bidirectional screw 15 is rotatably installed inside the transverse groove 13. There are two movable blocks 201 in total. The two movable blocks 201 are symmetrically threaded onto both ends of the bidirectional screw 15.

[0016] When the bidirectional screw 15 rotates, it drives two symmetrically connected movable blocks 201 to slide towards or away from each other along the transverse groove 13, causing the rectangular plate 202 and the clamping plate 206 to adjust their spacing to fit the plate. After the clamping plate 206 contacts the plate, it pushes the connecting plate 205 and the movable plate 204 to compress the telescopic spring 208. The pressure sensor 207 detects the deformation pressure of the telescopic spring 208 to provide feedback on the clamping force.

[0017] By setting a pressure sensor 207 and a telescopic spring 208 in the rectangular groove 203 of the clamping mechanism 2, and cooperating with the symmetrical movable block 201 structure driven by the bidirectional screw 15, the problem of difficult precise control of the clamping force at both ends in the prior art is solved. The pressure sensor 207 can detect the deformation pressure of the telescopic spring 208 in real time, and indirectly feed back the lateral clamping force of the clamping plate 206 on the SMC sheet. Combined with the fine-tuning control of the first servo motor 16 by the control board 12, it can avoid excessive clamping force causing deformation damage to the sheet or insufficient clamping force causing cutting displacement, thus significantly improving clamping stability and cutting accuracy. The cutting mechanism 3 includes side plates 31 welded above the platform 11 and located on both sides of the cutting groove 14. A long plate 32 is welded above the side plates 31. A linear module 33 is bolted to the inner side of the long plate 32. A slide plate 34 is provided on the outer side of the linear module 33. A vertical plate 35 is bolted to the front end of the slide plate 34. A second servo motor 36 is bolted to the inner side of the bottom end of the vertical plate 35. The output end of the second servo motor 36 extends through to the front side of the vertical plate 35 and is bolted to a cutting blade 37. A horizontal plate 38 is welded to the right side of the bottom end of the vertical plate 35. A third servo motor 39 is bolted to the inner side of the front end of the horizontal plate 38. The output end of the third servo motor 39 extends through to the front side of the horizontal plate 38 and is bolted to a grinding wheel 310.

[0018] The side plate 31 and the long plate 32 provide mounting support for the linear module 33. The linear module 33 drives the slide plate 34 to move the vertical plate 35 and the horizontal plate 38. The second servo motor 36 drives the cutting blade 37 to rotate to achieve cutting. The third servo motor 39 drives the grinding wheel 310 to rotate to achieve grinding. The cutting groove 14 provides clearance space for the cutting operation.

[0019] By arranging the cutting blade 37 and the grinding wheel 310 of the cutting mechanism 3 in a front-to-back configuration at the front ends of the vertical plate 35 and the horizontal plate 38, and with the linear module 33 running parallel to the cutting groove 14, the cutting and grinding operations are carried out simultaneously. Compared with the processing mode in the prior art where grinding is required separately after cutting, this layout allows the grinding wheel 310 to immediately trim the burrs on the cut after the cutting blade 37 completes the edge cutting of the board, reducing the process flow time and avoiding secondary positioning errors, thus greatly improving the efficiency and quality of SMC board edge processing.

[0020] The first servo motor 16 is bolted on the left side of the platform 11. The output end of the first servo motor 16 extends into the interior of the transverse groove 13 and is bolted to the left end of the bidirectional screw 15.

[0021] After the first servo motor 16 starts, it outputs power to directly drive the bidirectional screw 15 to rotate in the transverse groove 13, providing a power source for the sliding adjustment of the movable block 201 and realizing electric control of the clamping distance.

[0022] The rectangular plate 202 has columns 209 welded above both ends. A top plate 210 is bolted to the top of the columns 209. A cylinder 211 is bolted to the front end of the top plate 210. The output end of the cylinder 211 extends to the bottom of the top plate 210 and is bolted to a fixing plate 212.

[0023] The column 209 supports and fixes the top plate 210, and the top plate 210 provides an installation carrier for the cylinder 211. After the cylinder 211 is started, it drives the fixing plate 212 to move up and down. The fixing plate 212 presses down and contacts the upper surface of the plate, thereby achieving vertical positioning of the plate.

[0024] The control board 12 is bolted to the front of the platform 11. The control board 12 is electrically connected to the first servo motor 16, the cylinder 211, the linear module 33, the second servo motor 36, and the third servo motor 39.

[0025] The control board 12 receives and processes signals, and sends control commands to the first servo motor 16, cylinder 211, linear module 33, second servo motor 36, and third servo motor 39 to coordinate the operation of each component and realize the automated control of the device.

[0026] The horizontal groove 13 and the cutting groove 14 are vertically distributed on the upper surface of the platform 11. The horizontal groove 13 extends along the width direction of the platform 11. The distance between the clamping plate 206 of the clamping mechanism 2 and the cutting groove 14 is not less than the reserved width of the edge of the plate to be cut. The extension direction of the horizontal groove 13 is adapted to the clamping adjustment of the clamping plate 206 along the width direction of the plate. The vertical distribution of the horizontal groove 13 and the cutting groove 14 avoids structural interference. The distance between the clamping plate 206 and the cutting groove 14 ensures that the part of the plate to be cut extends out, leaving space for the cutting operation.

[0027] The linear module 33 of the cutting mechanism 3 is arranged along the length of the long plate 32, and the running trajectory of the linear module 33 is parallel to the extension direction of the cutting groove 14; the cutting blade 37 and the grinding wheel 310 are arranged in front and behind at the front ends of the vertical plate 35 and the horizontal plate 38.

[0028] The running trajectory of the linear module 33 is parallel to the cutting groove 14, ensuring that the cutting blade 37 moves stably along the cutting path; the front and rear arrangement of the cutting blade 37 and the grinding wheel 310 allows the grinding wheel 310 to follow up and grind immediately after the cutting blade 37 cuts, achieving synchronous processing.

[0029] Working principle and usage process of this utility model: The SMC sheet to be cut is placed stably on the upper surface of the platform 11, aligning the edge of the sheet to be cut with the cutting groove 14, while ensuring that both ends of the sheet are inside the clamping plates 206 on both sides. Based on the width of the SMC sheet to be cut, the control board 12 sends a command to the first servo motor 16, driving it to rotate the bidirectional screw 15 within the transverse groove 13. Since the two movable blocks 201 are symmetrically threaded onto both ends of the bidirectional screw 15, the rotation of the screw causes the movable blocks 201 to slide towards each other along the transverse groove 13 until the distance between the two rectangular plates 202 on both sides matches the width of the sheet. Then, the first servo motor 16 stops running and locks the screw. The control board 12 activates cylinder 211, which pushes fixed plate 212 downward until it contacts the upper surface of the plate and applies a preset pressure, thus achieving vertical positioning of the plate. Simultaneously, pressure sensor 207 detects the deformation pressure of the telescopic spring 208 within the rectangular groove 203 in real time, indirectly providing feedback on the lateral clamping force of clamping plate 206 on the side of the plate. This data is transmitted to the control board 12. If the pressure value deviates from the preset range, the system can fine-tune the position of movable block 201 to compensate, preventing excessive or insufficient clamping force. When pressure sensor 207 detects that the clamping force reaches a preset threshold, the control board 12 controls cylinder 211... 11. Maintaining pressure output, the movable block 201 is fixed in position under the self-locking action of the threaded screw 15, completing the stable clamping of the plate; the linear module 33 is activated, driving the slide plate 34 to move laterally along the long plate 32, so that the cutting blade 37 is aligned with the starting position of the edge to be cut on the plate, and the grinding wheel 310 is adjusted accordingly to the subsequent connection position of the cutting path; the linear module 33 drives the slide plate 34 to move at a constant speed along the cutting groove 14, and the high-speed rotating cutting blade 37 cuts the edge of the plate first; as the cutting blade 37 moves forward, the grinding wheel 310 following behind simultaneously deburrs and polishes the cut surface. This enables continuous "cutting-grinding" operations. During processing, the control board 12 monitors the signal from the pressure sensor 207 in real time. If the clamping force fluctuates due to the superposition of cutting and grinding forces, the pressure of the cylinder 211 or the state of the first servo motor 16 can be adjusted instantaneously to ensure that the material remains in a stable state. After the cutting and grinding are completed synchronously, the second servo motor 36 and the third servo motor 39 stop running at the same time, and the linear module 33 drives the slide plate 34 to reset to the initial position. The cylinder 211 drives the fixed plate 212 to reset upward, and the first servo motor 16 drives the bidirectional screw 15 to reverse, causing the clamping plates 206 on both sides to move in opposite directions to release the material.
