[0002] The clamp forming die is a die for producing clamp parts, which is usually used in the fields of pipeline connection, fixation, etc., and its working principle is to press metal or plastic material into the required clamp shape by the cooperation of upper and lower molds and mold cores in the die.

[0003] The Chinese patent with patent publication number CN217617278U discloses a clamp forming die, which comprises a base, a forming lower die, an upper die, a discharging mechanism and a top plate. The upper surface of the base is provided with the forming lower die, and the top plate is arranged above the base. The lower surface of the upper die is provided with the upper die through the discharging mechanism. The discharging mechanism comprises a discharging lead screw, a discharging sliding block, a bidirectional motor, a scraping plate and a connecting rod. One side of the lower surface of the upper die is provided with a pair of fixed plates, and the discharging lead screw is rotatably arranged between the two fixed plates. The discharging sliding block is threadedly sleeved on the discharging lead screw, and the upper die is fixed on the discharging sliding block. The two sides of the fixed plate away from the forming lower die are both fixed with the scraping plate through the connecting rod. This clamp forming die overcomes the problem that the clamps are tightly sleeved on the cylindrical upper die after stamping in the prior art, and workers are needed to take out the clamps, which is time-consuming and laborious. Manual taking out of the clamps also brings safety hazards to workers.

[0004] However, the existing forming die has the following problems: when the O-shaped clamp is formed, some O-shaped clamps will rebound after being formed, and the rebound of the clamps will cause changes in their shape or size, ultimately failing to meet the design requirements, and will also cause unstable fastening force, making the clamp installation not firm. Therefore, we propose a positioning clamp forming die. SUMMARY

[0009] According to the above technical scheme, the distance between the first hemispherical block and the last hemispherical block of the plurality of hemispherical blocks on the same side is half the length of the long plate.

[0010] According to the above technical scheme, the inner wall of the support frame is fixedly connected with a limiting rod, and the threaded sleeve is slidingly installed on the outer wall of the limiting rod.

[0016] (3) The cooperation of the hinged rod, protective plate, track block and short rod makes the protective plate be in front of the lower die and the round convex forming piece, thereby preventing unnecessary collision or injury of the clamp raw material during processing, and ensuring the safety of the workers, and preventing the workers from being accidentally contacted with the mechanical parts by hands or other objects, and causing the workers to be injured.

[0023] When in use, the raw material of the clamp to be shaped is placed in the lower mold 2, and then the worker drives the round convex forming member 4 to move towards the lower mold 2 by the upper mold driving member 3, so that the raw material of the clamp is shaped into an O-shaped clamp, and the shaped O-shaped clamp is hung on the round convex forming member 4, then the motor 52 is started, the output shaft of the motor 52 drives the threaded rod 53 to rotate, the rotation of the threaded rod 53 drives the threaded sleeve 54 to move along the limiting rod 514 towards the support table 1, the movement of the threaded sleeve 54 drives the U-shaped block 55 to move, the movement of the U-shaped block 55 drives the short rod 56 to move, the movement of the short rod 56 drives the extrusion block 57 to move, the movement of the extrusion block 57 first contacts the long column connected with the upper mold driving member 3 of the round convex forming member 4, at this time the long column of the round convex forming member 4 drives the extrusion block 57 to move along the inner wall of the U-shaped block 55 and compresses the spring one 58, then the extrusion block 57 continues to move and contacts the straight face rebounding above the O-shaped clamp, when the extrusion block 57 leaves the long column of the round convex forming member 4, the spring one 58 drives the extrusion block 57 to reset by its own elastic force, the reset of the extrusion block 57 makes the straight face rebounding above the O-shaped clamp be in a vertical state, so as to avoid the O-shaped clamp after shaping being in a rebounding state all the time, and ensure the shape of the O-shaped clamp, when the extrusion block 57 contacts the straight face rebounding above the O-shaped clamp, at this time the "√" shaped block 59 hooks the side face of the straight face above the O-shaped clamp, so as to ensure that the extrusion block 57 can take out the shaped O-shaped clamp from the round convex forming member 4; at the same time, the movement of the short rod 56 drives the long plate 511 to move, the movement of the long plate 511 drives the plurality of hemispherical blocks 512 to move, when the extrusion block 57 and the "√" shaped block 59 take out the O-shaped clamp from the round convex forming member 4, at this time the leftmost hemispherical block 512 first contacts the hemispherical surface of the Z-shaped block 510, so as to make the hemispherical block 512 push the long plate 511 to compress the spring two 513, at the same time, the long plate 511 pushes the short rod 56 to push the extrusion block 57 to extrude the straight face above the O-shaped clamp and stretch the spring one 58, when the hemispherical block 512 does not contact the hemispherical surface of the Z-shaped block 510, the spring one 58 and the spring two 513 reset by their own elastic force, so as to make the long plate 511 drive the extrusion block 57 to compress the straight face above the O-shaped clamp all the time, so as to make the rebounding angle of the O-shaped clamp change from 90 degrees to 100 degrees to rebound to change from 80 degrees to 90 degrees, so as to ensure that the O-shaped clamp taken out from the extrusion block 57 and the "√" shaped block 59 is in a correct shape.

Therefore, after the O-shaped clamp is taken off from the extrusion block 57 and the block 59, the worker can place the new clamp raw material into the U-shaped clamping block 62, and then reversely start the motor 52. The output shaft of the motor 52 drives the threaded rod 53 to rotate, and the rotation of the threaded rod 53 drives the threaded sleeve 54 to move towards the motor 52. At this time, the threaded sleeve 54 drives the L-shaped block 61, the U-shaped clamping block 62, the vertical rod 63 and the extrusion plate 64 to move towards the motor 52. When the U-shaped clamping block 62 drives the clamp raw material to move, the clamp raw material is resisted by the resistance block 67, so as to fall from the U-shaped clamping block 62 to the lower mold 2, thereby avoiding the manual feeding of the worker, and causing the worker to be pressed by the upper mold driving part 3 when the circular convex forming part 4 moves without attention, and causing the worker to be injured. At the same time, when the clamp raw material is inserted into the U-shaped clamping block 62, the clamp raw material drives the extrusion plate 64 to move upwards, and drives the extrusion plate 64 to drive the vertical rod 63 to move upwards, and at the same time, the spring three 65 is compressed. When the clamp raw material is placed, the spring three 65 drives the vertical rod 63 and the extrusion plate 64 to reset by the elastic force of the spring three 65. Therefore, the U-shaped clamping block 62 and the extrusion plate 64 can clamp the clamp raw material with different thicknesses.

[0025] Please refer to Figure 1 - Figure 8 On the basis of the above embodiment, in another embodiment of the present application, the short rod 56 is provided with an anti-touch device 7 away from the extrusion block 57. The anti-touch device 7 comprises a hinged rod 71, one end of the hinged rod 71 being hinged to the end of the short rod 56 away from the extrusion block 57, and the other end of the hinged rod 71 being hinged with a protective plate 72. The side surface of the supporting table 1 is fixedly connected with a track block 73, and the protective plate 72 is slidingly installed on the outer wall of the track block 73. Through the above structure, the protective plate 72 can be placed in front of the lower mold 2 and the circular convex forming part 4, so as to prevent the clamp raw material from colliding or being damaged during processing, and to ensure the safety of the worker. The worker avoids the problem of accidental contact of hands or other objects with mechanical parts and causes injury.

[0026] When the threaded sleeve 54 is moved towards the motor 52, the threaded sleeve 54 drives the U-shaped block 55 to move, the U-shaped block 55 drives the short rod 56 to move, the short rod 56 drives the protection plate 72 to move upwards along the track block 73 through the hinged rod 71, so that the protection plate 72 can be blocked in front of the lower mold 2 and the circular convex formed part 4, so as to prevent the clamp raw material from colliding or being damaged in the processing process, and to ensure the safety of the workers, so as to avoid the problem that the workers accidentally touch the mechanical parts with hands or other objects and are injured.
