Description

Technical Field

[0001] This utility model relates to the field of mold steel processing and grinding, specifically to an edge grinding device for mold steel processing. Background Technology

[0002] In the field of mold steel processing, the grinding of the edges and corners of rectangular block mold steel is a key process to ensure the precision and service life of the mold. Mold steel is a hard material (such as Cr12, H13, etc.), and if there are burrs, flash, or unevenness on the edges and corners, it will directly affect the subsequent mold assembly precision and the surface quality of the formed products. Therefore, it is necessary to use a special grinding device to achieve precise trimming of the edges and corners.

[0003] Existing mold steel edge grinding devices have significant limitations in practical applications, mainly due to design flaws in the clamping structure and grinding components:

[0004] On the one hand, the clamping structure significantly limits the grinding range. Currently, the mainstream clamping method is double-sided inward clamping, where cylinders or lead screws drive the clamping plates on both sides to apply pressure and fix the rectangular block of mold steel from both long sides. While this structure ensures the stability of the workpiece during grinding, it directly obstructs the corner areas of the short sides of the mold steel (such as the four apex corners of the rectangular block and the junctions of adjacent sides), preventing the grinding tool from directly contacting these areas. To complete full-corner grinding, the workpiece needs to be disassembled multiple times, the clamping direction adjusted, or the workpiece flipped. This not only increases the time cost of loading, unloading, and positioning but also easily leads to inconsistent corner grinding accuracy (such as chamfer dimension deviation) due to repeated positioning errors, severely reducing grinding efficiency.

[0005] On the other hand, the maintenance convenience of belt grinding structures is insufficient. Existing belt grinding devices typically connect the grinding belt to the drive wheel and tension wheel via bolts or clips. Replacement requires disassembling multiple components, making the operation cumbersome, and frequent replacements significantly disrupt the production process. Furthermore, belt tension adjustment relies on manual knobs or shims, making it difficult to quickly and accurately control the tension: excessive tension causes belt slippage, reducing grinding efficiency and producing irregular scratches; excessive tension accelerates belt wear and increases the load on the drive motor, shortening equipment lifespan. This adjustment method is highly dependent on operator experience, further impacting the stability and practicality of grinding operations.

[0006] With the increasing demands for processing efficiency and precision in the mold manufacturing industry, the shortcomings of existing equipment in terms of clamping flexibility, grinding integrity, and ease of maintenance have become prominent issues restricting the processing quality of mold steel edges and corners. Therefore, it is necessary to design an edge and corner grinding device for mold steel processing to solve these problems. Utility Model Content

[0027] It should be added that the fastener between the bracket 4 and the operating table 1 can clamp and fix the workpiece from the top and bottom. The cross-section of the sliding hole 5 is "+" shaped. The first sliding groove 2 corresponds to the sliding hole 5. After the fastener fixes the workpiece, it can facilitate the rotation of the workpiece, so that the operator can bring the workpiece close to the grinding part for edge grinding, avoid burrs on the surface of the workpiece, and improve the convenience and practicality of the equipment for edge grinding of the workpiece.

[0028] Specifically, the fixing component includes a first screw 6 that passes through the inner side of the first slide groove 2, a slider 7 that is fitted and screwed onto the outer side of the first screw 6, a connecting block 9 that is rotatably connected to the top of the slider 7 and a fixing washer 8, the fixing component also includes a sliding frame 10 that is slidably connected to the inner side of the sliding hole 5, an electric push rod 11 that is mounted on the top of the sliding frame 10, a mounting bracket 12 that is fixedly mounted on the bottom of the electric push rod 11 by bolts, a pressure block 13 that is rotatably connected to the inner side of the mounting bracket 12, an anti-slip pad 14 that is laid on the bottom of the pressure block 13, a guide block 24 that is fixedly connected to the bottom of the slider 7, the guide block 24 being embedded in the bottom of the first slide groove 2 and slidably connected thereto.

[0029] The connecting block 9 and the pressure block 13 have "I" shaped cross sections, and the slider 7 has a "convex" shaped cross section. The first screw 6 can drive the slider 7 to slide in the first slide groove 2. The guide block 24 can guide and limit the slider 7 to prevent it from deviating or shaking. The slider 7 can drive the pad 8 to support the workpiece upward through the connecting block 9. The sliding frame 10 slides in the sliding hole 5 without disengaging. The electric push rod 11 can drive the pressure block 13 to move up and down through the mounting frame 12 so that the anti-slip pad 14 at the bottom of the pressure block 13 is in contact with the upper surface of the workpiece. That is, the anti-slip pad 14 and the pad 8 press the workpiece downward and fix it. The operator can push the workpiece to rotate.

[0030] More specifically, the grinding component includes a motor 15 embedded on one side of the operating table 1. The motor 15 is connected to a drive shaft 16 via an output shaft. A fixed shaft 17 is installed on the top of the operating table 1 and on the other side of the second slide groove 3. A driven wheel 18 is fitted on the outside of the fixed shaft 17. A grinding belt 19 is fitted on the outside of the drive shaft 16 and the driven wheel 18. The grinding component also includes a second screw 20 that passes through the inside of the second slide groove 3. A moving block 21 is fitted on the outside of the second screw 20. A moving shaft 22 is fixedly installed on the top of the moving block 21. A rotating wheel 23 is fitted on the outside of the moving shaft 22. The grinding belt 19 is wrapped around the outside of the rotating wheel 23. A star screw 25 is screwed to the handle end of the second screw 20. A plurality of locking slots 26 arranged in a circle are opened at one end of the operating table 1.

[0031] Furthermore, the motor 15 drives the grinding belt 19 to rotate via the drive shaft 16. The grinding belt 19 drives the driven wheel 18 and the rotating wheel 23 on the outside of the fixed shaft 17 to rotate. The rotating wheel 23 can adjust the tension of the grinding belt 19. The second screw 20 can drive the moving block 21 to slide in the second slide groove 3. After the second screw 20 rotates, it is screwed to it by the star screw 25. Then, the star screw 25 is inserted into the locking groove 26 for screwing in, so that the star screw 25 locks and prevents the second screw 20 from retracting. The moving block 21 drives the rotating wheel 23 to move via the moving shaft 22. The rotating wheel 23 moves closer to or away from the middle position between the drive shaft 16 and the fixed shaft 17, so as to facilitate the removal and replacement of the grinding belt 19 and the adjustment of the tension of the grinding belt 19, thereby improving the convenience and stability of the grinding belt 19 in grinding the edges and corners of the workpiece.

[0032] Working principle: First, rotate the first screw 6, causing the slider 7 to slide in the first groove 2. At the same time, the slider 7 causes the guide block 24 to slide at the bottom of the first groove 2. Simultaneously, the slider 7 drives the pad 8 to support the workpiece upward through the connecting block 9. The electric push rod 11 drives the pressure block 13 to move downward through the mounting bracket 12. That is, the anti-slip pad 14 and the pad 8 press and fix the workpiece downward. Then, start the motor 15, which drives the grinding belt 19 to rotate through the drive shaft 16. At the same time, the grinding belt 19 drives the driven wheel 18 and the rotating wheel 23 on the outside of the fixed shaft 17 to rotate, so that the edges and corners of the workpiece are close to the grinding belt 19 for grinding.
