Description

Technical Field

[0001] The invention belongs to the technical field of die-casting processing, and in particular relates to a metal part trimming device. Background Art

[0002] Die casting is a common metal manufacturing process used to produce high-precision, high-strength metal parts. The steps of die casting generally include: mold design and manufacturing, metal melting, mold preparation, injection, cooling, mold opening, excess material removal, post-processing and other steps. During the die casting process, excess materials such as gates and flash edges are often formed. These excess materials need to be removed to ensure the smoothness and geometric accuracy of the part surface. At the same time, the surface of die-cast parts usually has some roughness or pores. Surface treatment methods such as grinding and polishing can improve the appearance quality of the parts and improve their corrosion resistance. For some parts that require precise dimensions or special shapes, such as holes, grooves, etc., machining may be required after die casting to meet design requirements. Some die-cast parts may need to undergo processes such as heat treatment or surface coating to improve their mechanical properties, wear resistance or corrosion resistance.

[0003] There are often many problems with the existing trimming devices used in the process of trimming die-cast parts during subsequent processing. For example, when trimming a tubular die-casting with a circular structure, both the inner and outer ring edges need to be trimmed. This results in the need to switch the fixing method during the fixation of the die-casting to perform trimming at different positions. The existing trimming devices are often switched and fixed manually. At the same time, the tubular die-casting sometimes needs to be trimmed at both ends. Combined with the difference between the inner and outer edges, this results in the trimming process of the tubular die-casting being not continuous enough, resulting in low efficiency in trimming the die-casting.

Then the third motor in the bottom clamping drive mechanism rotates, and the corresponding cross slot head is driven to rotate by the rotation of the adjusting screw block, and the multiple clamping claws on one side of the inner ring plate in the double clamping mechanism are brought close to each other through the bottom clamping adjustment mechanism, thereby releasing the clamping fixation of the inner wall.

By installing a clamping adjustment mechanism at the top and bottom of the double clamping mechanism, it is realized that when switching between different grinding methods, the clamping method can be automatically switched by cooperating with the corresponding two clamping drive mechanisms. The clamping adjustment mechanism at the top can realize the clamping and fixing of the outer wall of the tubular die-casting, and the clamping adjustment mechanism at the bottom can realize the supporting and fixing of the inner wall of the tubular die-casting. Improve the continuity of the trimming process of the integral tubular die-casting and improve the efficiency of trimming; (2) The present invention designs a clamping drive mechanism. When switching the clamping mode, the driving cylinders in the clamping drive mechanisms at the top and bottom of the trimming drive mechanism simultaneously pull the L-shaped connecting strip, thereby driving the two adjusting screw blocks to be inserted into the two corresponding cross slot heads.

At this time, the two fixing modes are started to be fixed at the same time, and then the previous clamping mode is withdrawn, so as to achieve the purpose of changing the fixing mode.

The first linear motor 302, the second linear motor 306 and the electric cylinder 308 in the trimming drive mechanism 3 can drive the trimming rod 312 to complete multi-directional movement, and cooperate with the second motor 310 to drive the locking mounting block 311 and the trimming rod 312 to rotate to trim the outer wall of the tubular die casting 8. After the trimming is completed in this step, the trimming rod 312 is reset, and the first motor 105 drives the rotating frame 103 to rotate 4 5 degrees, the tubular die-casting 8 is continued to be installed on the double clamping mechanism 6 at the position of the control device 9, and then the rotating frame 103 continues to rotate 45 degrees, and the first tubular die-casting 8 begins to perform the second step of trimming. At this time, the driving cylinders 401 in the clamping driving mechanism 4 at the top and bottom of the trimming driving mechanism 3 simultaneously pull the L-shaped connecting strip 403, thereby driving the two adjusting screw blocks 409 to be inserted into the two corresponding cross groove heads 705, and in the process of continuous pulling, the first square hole sleeve 406 receives part of the first telescopic limiting square rod 410, and compresses the reset spring 4 07, to ensure that when the cross slot head 705 is displaced and changed with the spiral rotation, the adjusting screw block 409 can always fit the cross slot head 705 to complete the power transmission, and then the third motor 405 in the top clamping drive mechanism 4 starts to drive the first square hole sleeve 406 to rotate, and drives the adjusting screw block 409 to rotate through the first telescopic limiting square rod 410, and then drives the bevel gear ring 606 on one side of the outer ring plate 604 meshing with it through the rotation of the bevel gear 708 in the top clamping adjustment mechanism 7, so as to drive the vortex teeth 607 on the other side of the outer ring plate 604 The multiple clamping claws 608 begin to approach each other until the clamping rods 609 on the multiple clamping claws 608 clamp the outer wall of the tubular die-casting 8, and then the third motor 405 in the bottom clamping drive mechanism 4 rotates, and the corresponding cross slot head 705 is driven to rotate by adjusting the rotation of the screw block 409, and the multiple clamping claws 608 on one side of the inner ring plate 605 in the double clamping mechanism 6 are brought close to each other through the bottom clamping adjustment mechanism 7, thereby releasing the clamping fixation of the inner wall, and finally the inner wall of the tubular die-casting 8 is trimmed by the trimming drive mechanism 3 at this position;

[0046] Similarly, after step two is completed, the limit ring 102 is rotated to continue rotating 45 degrees, and the double clamping mechanism 6 at the position of the control device 9 continues to install the tubular die-casting 8, and the tubular die-casting 8 that has undergone two steps is removed and reverse clamped and fixed. Similarly, the other end is trimmed until it returns to the original position after four steps of complete trimming. After removal, the unprocessed tubular die-casting 8 is installed to achieve a cyclic trimming operation.

[0047] The above description is only a preferred embodiment of the present invention and is not intended to limit the protection scope of the present invention.
