Description

Technical Field

[0001] This utility model belongs to the field of mold punch technology, specifically, it relates to a grinding device for processing mold punches. Background Technology

[0002] A punch is a metal part mounted on a stamping die. It is used to come into direct contact with the material, causing the material to deform and cut. In the current process of machining the head of a die punch, the die punch is first mounted on the machining table, and then the die punch is ground by the workers using a grinding machine.

[0003] The utility model patent with application number CN202120391848.7 (publication number CN214322807U) discloses a grinding fixture for the R-angle of a mold punch. One end of the mold punch is fixed by a chuck and rotated at high speed by a power box. A cylinder pushes the first slide to the left so that the abrasive plate contacts the punch for grinding. At the same time, the tilt angle of the mounting plate is adjusted by extending or retracting the electric telescopic rod. The R-angle of the punch is ground by adjusting the height of the second slide.

[0004] The aforementioned patent can grind the punch at a certain angle. However, in actual processing, the circumferential surface and end face of the punch also need to be ground. The angle adjustment range of the aforementioned patent is limited, resulting in a single grinding function. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a grinding device for processing mold punches, which can grind the end face, circumferential surface and R-angle, and solves the technical problem that the angle adjustment range is limited during grinding, resulting in a single grinding function and the inability to grind the end face and circumferential surface.

[0006] This utility model is implemented as follows:

[0007] This utility model provides a grinding device for processing mold punches, which has a processing table, a support plate fixedly installed on the left side of the processing table, a chuck for fixing the punch installed on the right wall of the support plate, a horizontal moving component on the right side of the processing table, a vertical moving component at the upper end of the horizontal moving component, and a grinding component for processing the punch at the front end of the vertical moving component.

[0008] The grinding assembly includes a vertical plate fixedly mounted on the vertical moving assembly. A rotating disc is rotatably connected to the vertical plate, and a circumferentially rotating grinding blade is rotatably connected to the disc. The disc and the vertical plate are jointly provided with a transmission assembly for rotating the grinding blade.

[0009] Based on the above technical solution, the grinding device for processing mold punches of this utility model can be further improved as follows:

[0010] Furthermore, a limiting post is fixedly installed on the vertical plate at the top and left end of the center line of the disk, and a limiting block is fixedly installed on the disk between the two limiting posts.

[0011] Furthermore, the portion of the upright plate located between the two limiting posts is arranged in an arc shape, and the curvature is consistent with that of the disc. Multiple insertion slots are equidistantly provided on the arc-shaped part of the upright plate and on the outer side of the disc. The multiple insertion slots are located between the two limiting posts. An insertion rod is inserted into one of the insertion slots. Both the insertion rod and the limiting post protrude from the limiting block.

[0012] Furthermore, the transmission assembly includes two bearing seats. The bearing seat on the right is fixedly installed on the upright plate and located at the right end of the disk, while the bearing seat on the left is fixedly installed on the disk and located near the outer edge of the disk. Each bearing seat is rotatably connected to a rotating column via a bearing.

[0013] Furthermore, each of the rotating columns is slidably connected to one end of a plurality of connecting rods, and the ends of the connecting rods that are close to each other are fixedly installed with one end of a hinge seat, and the two hinge seats are hinged to each other.

[0014] The outer end of the rotating column on the left is fixedly connected to the grinding blade, which is located outside the vertical plate. The outer end of the rotating column on the right is connected to the output shaft of the drive motor B, which is fixedly mounted on the vertical plate.

[0015] Furthermore, a rotating rod is fixedly installed in the middle of the disk, and the rotating rod is rotatably connected to the vertical plate through a bearing;

[0016] The lower end of the disc is provided with a driving cylinder. The fixed end of the driving cylinder is hinged to the vertical plate, and the movable end of the driving cylinder is hinged to the push rod. The push rod is fixedly mounted on the disc.

[0017] Compared with the prior art, the beneficial effects of the grinding device for processing mold punches provided by this utility model are:

[0018] By setting a rotating disk, the grinding blade can be tilted from 0 to 90 degrees under the restriction of the limiting post and the limiting block, thereby adjusting the grinding angle and grinding the circumferential surface and the end surface, and can also produce grinding at other angles.

[0019] By setting up a transmission assembly, the drive motor B that drives the grinding blade to rotate is not mounted on the disc, thus avoiding vibrations from the drive motor B that could affect the drive cylinder. The rotation of the disc drives the grinding blade to rotate circumferentially, and the transmission assembly drives the grinding blade to rotate around its central axis. Attached Figure Description

[0032] Example 1

[0033] like Figure 1-4 As shown, this utility model provides a grinding device for processing mold punches, which has a processing table 1, a support plate 2 fixedly installed on the left side of the processing table 1, a chuck 21 for fixing the punch installed on the right wall of the support plate 2, a horizontal moving component 11 provided on the right side of the processing table 1, a vertical moving component 12 provided at the upper end of the horizontal moving component 11, wherein a grinding component 3 for processing the punch is provided at the front end of the vertical moving component 12.

[0034] The grinding assembly 3 includes a vertical plate 31 fixedly mounted on the vertical moving assembly 12. A rotating disc 32 is rotatably connected to the vertical plate 31. A circumferentially rotating grinding blade 4 is rotatably connected to the disc 32. The disc 32 and the vertical plate 31 are jointly provided with a transmission assembly for rotating the grinding blade 4.

[0035] Optionally, in the above technical solution, a limiting post 33 is fixedly installed on the vertical plate 31 at the top and left ends of the center line of the disc 32, and a limiting block 34 is fixedly installed on the disc 32 between the two limiting posts 33.

[0036] Optionally, in the above technical solution, the portion of the upright plate 31 located between the two limiting posts 33 is arranged in an arc shape, and the arc is consistent with that of the disc 32. Multiple insertion slots 35 are equidistantly provided on the arc-shaped part of the upright plate 31 and on the outer side of the disc 32. The multiple insertion slots 35 are located between the two limiting posts 33. An insertion rod 36 is inserted into one insertion slot 35. Both the insertion rod 36 and the limiting post 33 protrude from the limiting block 34.

[0037] Optionally, in the above technical solution, the transmission assembly includes two bearing seats 41. The right bearing seat 41 is fixedly installed on the upright plate 31 and located at the right end of the disc 32. The left bearing seat 41 is fixedly installed on the disc 32 and located near the outer edge of the disc 32. Each bearing seat 41 is rotatably connected to a rotating column 42 through a bearing.

[0038] Optionally, in the above technical solution, one end of a plurality of connecting rods 43 is slidably connected to the rotating column 42, and one end of a hinge seat 45 is fixedly installed on the end of the connecting rods 43 that are close to each other, and the two hinge seats 45 are hinged to each other.

[0039] That is, the two opposing links 43 are connected by a hinge seat 45, so that the two opposing links 43 rotate synchronously;

[0040] Among them, the multiple connecting rods 43 on one rotating column 42 are distributed in a square; the multiple connecting rods 43 on one rotating column 42 have the same length, and the length of the connecting rod 43 on the right rotating column 42 is greater than the length of the connecting rod 43 on the left rotating column 42.

[0041] The outer end of the left rotating column 42 is fixedly connected to the grinding blade 4, which is located outside the vertical plate 31. The outer end of the right rotating column 42 is connected to the output shaft of the drive motor B44, which is fixedly mounted on the vertical plate 31.

[0042] Optionally, in the above technical solution, a rotating rod 321 is fixedly installed in the middle of the disc 32, and the rotating rod 321 is rotatably connected to the vertical plate 31 through a bearing;

[0043] The lower end of the disc 32 is provided with a drive cylinder 37. The fixed end of the drive cylinder 37 is hinged to the vertical plate 31, and the movable end of the drive cylinder 37 is hinged to the push rod 322. The push rod 322 is fixedly mounted on the disc 32.

[0044] Furthermore, the horizontal moving component 11 and the vertical moving component 12 have the same structure and are perpendicular to each other, including a U-shaped fixed base 13. A lead screw 14 is rotatably connected inside the fixed base 13, and a screw block 15 is slidably connected inside the lead screw 14 and threadedly connected to the fixed base 13 (the screw block 15 abuts against the inner wall of the long side of the fixed base 13). A drive motor C16 is fixedly installed on the outer wall of the short side of the fixed base 13. The output shaft of the drive motor C16 passes through the short side of the fixed base 13 and is connected to the lead screw 14 through a coupling.

[0045] The long side outer wall of the fixing seat 13 of the horizontal moving component 11 is fixedly installed on the processing table 1, the short side outer wall of the fixing seat 13 of the vertical moving component 12 (i.e. the side opposite to the drive motor C16) is fixedly installed on the screw block 15 of the horizontal moving component 11, and the grinding component 3 is fixedly installed on the screw block 15 of the vertical moving component 12.

[0046] Furthermore, under the constraint of the two limiting posts 33, the maximum angular movement range of the limiting block 34 is 90°, that is, the disk 32 can generate a rotation of 0-90°;

[0047] Preferably, there are three insertion slots 35. After the insertion rod 36 is inserted, it cooperates with any one of the limiting posts 33 to limit the rotation angle of the limiting block 34 to 30°, 45° and 60° in sequence. If other angles are required, they can be achieved by driving the cylinder 37.

[0048] The center line of the limiting block 34 coincides with the center line of the grinding blade 4, which facilitates the movement of the grinding blade 4 to the appropriate position.

[0049] Working principle:

[0050] In use, the punch to be polished is clamped by the chuck 21, the height of the polishing blade 4 is adjusted by the vertical moving component 12, and the disc 32 is rotated by the drive cylinder 37 to achieve the required polishing angle. After rotating to the required angle, the polishing blade 4 is rotated by the transmission component, and the polishing blade 4 is moved to the left by the horizontal moving component 11 to polish the punch.

[0051] The transmission assembly works as follows: the drive motor B44 is started to drive the right rotating column 42 connected to its output shaft to rotate in place. The right rotating column 42 first drives the right connecting rod 43 to rotate circumferentially. Through the hinge of the two sets of connecting rods 43 and the sliding connection between the left connecting rod 43 and the left rotating column 42, the left rotating column 42 is driven to rotate in the same way, and the grinding blade 4 rotates accordingly.

[0052] Because there is an angle of less than 180 degrees between the connecting rods 43 on the two rotating columns 42, the sliding connection between the connecting rods 43 and the rotating columns 42 causes the ends of the two connecting rods 43 that are far apart from each other to extend out of the rotating columns 42 in an alternating manner. Figure 1-2From the perspective of the pivot 42, the shortest link 43, located outside the pivot 42, extends out of the pivot 42 first.

[0053] The rotation adjustment method of the disc 32 is as follows: start the drive cylinder 37 to extend and retract its movable end. Since both ends of the drive cylinder 37 are hinged, the disc 32 can be rotated by pushing the push rod 322 to move left and right.

[0054] When it is necessary to grind the end face, rotate until the limit block 34 abuts against the limit post 33 at the left end and the grinding blade faces to the left. When it is necessary to grind the circumferential surface, rotate until the limit block 34 abuts against the limit post 33 at the upper end and the grinding blade faces upward.

[0055] When it is necessary to grind specific angles of 30°, 45° and 60°, insert the plug rod 36 into the corresponding plug slot 35 and rotate it so that the limit block 34 abuts against the plug rod 36, and the grinding blade is tilted at a specific angle.

[0056] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
