DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] Example 1

[0021] See also Figures 1 to 4 , which is the first embodiment of the utility model, and this embodiment provides a technical solution: a part processing stamping structure, comprising a base 1 and an L-shaped vertical plate 2 welded and fixed on the top of the base 1, a cylinder 3 is fixed to the top surface of the L-shaped vertical plate 2 by bolts, the model of the cylinder 3 is SC-50X50-S, a piston rod 31 is arranged at the bottom end of the cylinder 3, and the bottom end of the piston rod 31 penetrates to the bottom of the L-shaped vertical plate 2, and also comprises a punch head 4 installed at the bottom of the piston rod 31, a top seat 41 is welded and fixed to the top surface of the punch head 4, a sleeve 42 is welded and fixed to the top of the top seat 41, the sleeve 42 is movably sleeved on the surface of the piston rod 31, and an adjustment structure 5 is arranged between the sleeve 42 and the piston rod 31;

[0022] The adjusting structure 5 comprises a sliding cylinder 51, a stop sleeve 52, a limiting structure 53, a transverse penetration rod 56 and a through hole 57. The sliding cylinder 51 and the stop sleeve 52 are welded and fixed. The sliding cylinder 51 and the stop sleeve 52 are both slidably sleeved on the surface of the sleeve 42. A plurality of through holes 57 corresponding to the transverse penetration rod 56 are penetrated through the surface of the piston rod 31. Two insertion holes 58 for the transverse penetration rod 56 to be inserted are symmetrically provided on the top surface of the sleeve 42. The transverse penetration rod 56 penetrates one of the through holes 57 through the insertion holes 58, and the two ends of the transverse penetration rod 56 are respectively located in the two insertion holes 58. The transverse penetration rod 56 after penetration can stabilize and limit the sleeve 42, thereby ensuring the installation stability of the punch head 4. The stop sleeve 52 wraps and covers the two insertion holes 58, which can block the transverse penetration rod 56. The blocking and limiting function ensures the stable installation of the punch head 4. The limiting structure 53 is arranged between the sliding cylinder 51 and the sleeve 42. The limiting structure 53 includes an inner sliding groove 533 opened inside one side of the sliding cylinder 51. A spring 534 and a movable block 535 are arranged in the inner sliding groove 533. An annular groove 536 corresponding to the movable block 535 is opened on the surface of the sleeve 42. The end of the movable block 535 pops out into the annular groove 536, which can play a stable limiting role for the sliding cylinder 51 in daily use, ensuring that the blocking sleeve 52 can stably block and limit the transverse penetration rod 56. A side shift block 531 is also arranged on the surface of one side of the sliding cylinder 51. A side pull rod 532 is welded and fixed at the inner center of the side shift block 531. The end of the side pull rod 532 passes through the inner sliding groove 533. The groove 533 is fixed with the movable block 535. At the later stage, the operator only needs to pull the side shift block 531 sideways, so that the side pull rod 532 moves sideways with the movable block 535, and compress the spring 534 until the end of the movable block 535 moves out of the annular groove 536, so that the limit on the sliding cylinder 51 can be released. At this time, the operator can slide the sliding cylinder 51 down, so that the stop sleeve 52 moves down to the bottom of the insertion hole 58, and no longer blocks the transverse penetration rod 56. At this time, the operator can pull out the transverse penetration rod 56 to release the limit on the sleeve 42, and then slide the sleeve 42 up and down to change the height of the punch head 4, or directly slide the sleeve 42 continuously down to realize the separation of the punch head 4 and the piston rod 31, and the operator can When sliding down to adjust the height of the punch head 4, when the punch head 4 is adjusted to a suitable height, it is only necessary to insert the transverse penetration rod 56 back into the insertion hole 58 again, and penetrate the through holes 57 at other positions, so that the sleeve 42 can be limited by the transverse penetration rod 56 again. At this time, the operator slides the sliding cylinder 51 up again, so that the blocking sleeve 52 covers the two insertion holes 58 on the inside again, which can block and limit the transverse penetration rod 56. At the same time, the movable block 535 will be inserted into the annular groove 536 under the push of the spring 534, so as to limit the sliding cylinder 51 and the blocking sleeve 52 themselves, and ensure the stability of the punch head 4 after the height is adjusted. When the initial height of the punch head 4 changes, the height of the punch head 4 will also change when the piston rod 31 is formed after the subsequent cylinder 3 is started.So as to meet different stamping processing requirements.

[0023] A side hole communicating with the inner slide groove 533 is formed on the surface of the sliding cylinder 51 , and the side hole corresponds to the side pull rod 532 , so that the side pull rod 532 can pass through smoothly.

[0024] One end of the spring 534 is fixed to the inner wall of the inner slide groove 533 , and the other end of the spring 534 is fixed to the movable block 535 , thereby ensuring the installation stability of the spring 534 .

[0025] The side shift block 531 is C-shaped, and the upper and lower ends of the side shift block 531 extend to the upper and lower surfaces of the sliding cylinder 51 respectively. The C-shaped structural design can facilitate subsequent operators to pull the limiting structure 53 sideways by hand.

[0026] Among them, a stamping table is also provided on the top surface of the base 1, and the stamping table is directly below the stamping head 4. Later, the parts to be stamped can be placed on the stamping table, and then the cylinder 3 is started, so that the piston rod 31 moves down with the stamping head 4 to realize the stamping processing of the parts by the stamping head 4.

[0027] Example 2

[0028] See also Figures 1 to 5 , which is the second embodiment of the utility model, is based on the previous embodiment, and the difference is that the fastening bolts 54 and the anti-slipping blocking strips 55 can be provided to play a role in blocking and preventing slipping when the subsequent sliding cylinder 51 and the blocking sleeve 52 slide up.

[0029] Specifically, the adjustment structure 5 also includes a fastening bolt 54 and an anti-slip bar 55. The anti-slip bar 55 is fixed to the top of the sleeve 42 by the fastening bolt 54, and one end of the anti-slip bar 55 extends to one side of the sleeve 42. At this time, the end of the anti-slip bar 55 is above the retaining sleeve 52, which can play a blocking and anti-slip role when the subsequent sliding cylinder 51 and the retaining sleeve 52 slide up, and prevent the retaining sleeve 52 from sliding directly off the top of the sleeve 42. A threaded groove corresponding to the fastening bolt 54 is provided on the top surface of the sleeve 42, and one end of the anti-slip bar 55 passes through a bolt hole corresponding to the fastening bolt 54. The threaded end of the fastening bolt 54 passes through the bolt hole and is screwed into the threaded groove, so that the anti-slip bar 55 can be smoothly fixed by the fastening bolt 54.

[0030] Although the embodiments of the present invention have been shown and described (see the above detailed description for details), it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
