Description

Technical Field

[0001] The utility model relates to the technical field of long bolt processing, in particular to a punching machine with an automatic clamping function for processing long bolts. Background Art

[0002] A long bolt is a bolt with a longer length, and bolts are a kind of mechanical parts that are used in large quantities nowadays. Among them, a punching machine is a machine that uses pressure to deform metal and stamp it into various required structures. In the production and processing of long bolts, corresponding punching machines are often used for processing. It usually electromagnetically burns the long steel column red first, and then puts the long steel column into the lower mold, and makes the red-burned end outside the lower mold, and then performs a stamping operation to deform the red-burned end into a nut shape.

[0003] A Chinese patent discloses a punching machine for processing long bolts with an automatic clamping function, the publication number of which is CN214768120U. The article proposes "comprising a base; an auxiliary mechanism, the bottom of which is arranged on the top of the base; a clamping mechanism, the bottom of which is arranged on the top of the auxiliary mechanism; a power mechanism, the bottom of which is arranged on the top of the auxiliary mechanism; a lifting mechanism, the left side of which is arranged on the right side of the base; an automatic mechanism, the right side of which is arranged on the left side of the lifting mechanism; and the clamping mechanism comprises a clamping bottom plate. The utility model provides a long bolt with an automatic clamping function. The punching machine for processing bolts has a function of using the first clamping rod and the second clamping rod in the clamping mechanism to assist in fixing the mold on the top of the support, so as to prevent the vibration of the punching machine during processing from causing mold deviation and resulting in product defects. However, the prior art uses bolts to lock and fix the mold, which is not easy to cause displacement deviation. However, after the long nut-shaped bolt is placed in the lower mold, there is a certain gap between the two, so that during stamping, the long nut-shaped bolt is easily vibrated, resulting in a certain amount of displacement inside the lower mold, which will affect the quality of the final nut forming and cause product defects. Therefore, it is very necessary to design a punching machine for processing long bolts with automatic clamping function. Utility Model Content

[0028] The self-clamping assembly 4 includes a reserved groove 409, which is arranged at an equal angle on the upper end of the inner wall of the lower mold 2. A clamping groove 404 is arranged inside the lower mold 2 at one end of the reserved groove 409. The upper and lower ends of the inner wall of the clamping groove 404 are fixedly connected with a damper 403. One end of the damper 403 is fixedly connected with a sliding frame 408 extending into the reserved groove 409. One end of the sliding frame 408 is fixedly connected with a clamping block 407. The sliding frame 408 is fixedly connected with a clamping block 407. A return spring 405 is wound around the surface of the damper 403 at the end, and one end of the return spring 405 is fixedly connected to the inner wall of the clamping groove 404. After the rib-shaped long bolt is inserted into the lower mold 2, the elastic force of the return spring 405 can be used to move the sliding frame 408 to drive the clamping block 407 to move and tightly clamp on the surface of the rib-shaped long bolt, thereby reducing the gap between the rib-shaped long bolt and the inner wall of the lower mold 2, thereby realizing auxiliary clamping and fixing of the rib-shaped long bolt.

[0029] In this embodiment, a sliding groove 402 is opened on the inner wall of the clamping groove 404, and sliders 401 that slide with the inside of the sliding groove 402 are fixedly connected at both ends of one side of the sliding frame 408. The sliding of the slider 401 in the sliding groove 402 makes the sliding frame 408 slide back and forth more smoothly.

[0030] In this embodiment, the upper end of one side of the clamping block 407 is beveled, and there are five clamping blocks 407 distributed at equal angles. The beveled clamping blocks 407 make it smoother to insert the long bolt into the lower mold 2.

[0031] In this embodiment, anti-skid grooves 406 are evenly spaced on one side of the clamping block 407. The cross-section of the anti-skid grooves 406 is serrated. The serrated anti-skid grooves 406 are used to improve the friction clamping stability between the surface of the clamping block 407 and the surface of the long bolt.

[0032] In this embodiment, the cross-section of the sliding frame 408 is in an inverted U shape, and one end of the sliding frame 408 is fixedly connected to one side of the clamping block 407 by bolts. The welded inverted U-shaped sliding frame 408 is used to improve the strength of the connection structure between the clamping block 407 and the sliding frame 408.

[0033] Example 2

[0034] Based on Example 1, a preferred embodiment of the punching machine for processing long bolts with automatic clamping function provided by the utility model is as follows: Figures 1 to 5 As shown: the adjustment component 5 includes a fixing groove 508, which is opened at the lower end of the punch body 1, and the inner bottom wall of the fixing groove 508 is fixedly connected to a servo motor 501, and the output end of the servo motor 501 is fixedly connected to a threaded rod 505 through a coupling, and the surface of the threaded rod 505 is threadedly connected to a threaded block 504, and the threaded block 504 is equiangularly fixedly connected to a load-bearing rod 502 extending to the inside of the lower mold 2, and the top of the load-bearing rod 502 is fixedly connected to a bearing block 506, and the threaded rod 505 is driven to rotate by starting the servo motor 501, so that the threaded block 504 and the load-bearing rod 502 slide and drive the bearing block 506 to slide inside the lower mold 2, so that the sliding height of the bearing block 506 can be adjusted according to the different lengths of the long bolts.

[0035] In this embodiment, there are four load-bearing rods 502 distributed at equal angles, and the two ends of the load-bearing rod 502 are welded between the top of the threaded block 504 and the bottom of the bearing block 506 to form an integrated structure. The use of the load-bearing rods 502 distributed at equal angles facilitates the firm support and bearing of the bearing block 506.

[0036] In this embodiment, a limiting groove 507 is provided on the inner wall of the fixing groove 508, and limiting blocks 503 are fixedly connected at both ends of the threaded block 504 and slidably cooperate with the inside of the limiting groove 507. The sliding of the limiting block 503 in the limiting groove 507 improves the stability of the up and down sliding of the thread of the threaded block 504.

[0037] The working principle and use process of the utility model are as follows: first, the sliding height of the bearing block 506 is adjusted according to the different lengths of the sprocket-shaped long strip bolts. At this time, the servo motor 501 is started to drive the threaded rod 505 to rotate, and the threaded rod 505 and the threaded block 504 are matched with each other so that the threaded block 504 slides and drives the load-bearing rod 502 to slide, thereby making the height of the bearing block 506 sliding inside the lower mold 2 adjustable according to the different lengths of the sprocket-shaped long strip bolts, thereby improving its applicability;

[0038] Then, the rib-shaped long strip bolt is placed inside the lower mold 2, and the red-hot end is exposed outside the lower mold 2. At this time, the clamping block 407 moves, driving the sliding frame 408 to slide to compress the damper 403 and the return spring 405, and then the elastic force of the return spring 405 can be used to make the sliding frame 408 move to drive the clamping block 407 to move and tightly clamp on the surface of the rib-shaped long strip bolt, thereby reducing the gap between the rib-shaped long strip bolt and the inner wall of the lower mold 2, realizing the auxiliary clamping and fixing of the rib-shaped long strip bolt, and improving the quality of the stamping processing of the rib-shaped long strip bolt nut;

[0039] Then, the driving mechanism inside the punch body 1 is used to make the linkage rod work to drive the punch head 3 to descend, so that one end of the long bolt is burned red and deformed to realize the nut punching process.

[0040] The above are only preferred embodiments of the present invention and are not intended to limit the present invention.
