Description

Technical Field

[0001] The utility model relates to the technical field of stamping machines, and particularly relates to a pressing and rebounding buffer structure of a stamping machine. Background Art

[0002] With the development of the social commercial economy, more and more enterprises in the business environment are becoming more standardized. Many enterprises have clear rules and regulations for some relevant documents that need to be stamped within the enterprise and in external cooperation. And a large number of enterprises gather the relevant seals of the enterprise in one department for management to prevent the seals from being misused or stolen. Since modern enterprises need to stamp a lot of documents, generally a stamping machine is selected to stamp the documents. When the existing stamping machine is in use, it usually has an automatic stamp-return function, that is, after the stamping is completed, the stamp will automatically return to the stamping machine to avoid damage to the stamp. Generally, a pulling spring is set in the stamping machine to pull the stamp back into the stamping machine. Since the pulling spring has been stretched to the limit length when it is connected, the force for pulling back the stamp is relatively large. Often when pulling back the stamp, the components on the upper side in the stamping machine will collide with the slider control assembly of the stamping machine, which is likely to cause damage to the stamping over a long time. Content of the Utility Model

[0003] Utility Model Objective: The technical problem to be solved by the utility model is to provide a pressing and rebounding buffer structure of a stamping machine, which solves the problem that the stamp of the existing stamping machine is prone to collision and damage when being pulled back.

[0004] Technical Solution

[0005] To solve the above problems, the technical solution provided by the utility model is as follows:

[0006] A pressing and rebounding buffer structure of a stamping machine includes a mating slider and a rebounding buffer structure. The mating slider is installed in a slider control assembly, and the slider control assembly includes a locking tongue, and the mating slider is fixedly installed on the locking tongue.

[0007] Further, the rebounding buffer structure includes a rebounding buffer housing. One side of the rebounding buffer housing facing the mating slider is provided with an opening, and the rebounding buffer housing is a vertical structure.

[0008] Further, a rebounding buffer slider is slidably arranged in the rebounding buffer housing.

[0009] Further, a protruding block is arranged on the rebounding buffer slider, and the protruding block extends out of the opening of the rebounding buffer housing.

[0010] Further, the mating slider slides in and out following the locking tongue.

[0011] Further, after the mating slider slides outwards, it partially overlaps with the protruding block.

[0012] Furthermore, the slider control assembly further includes a steering gear, and a gear is provided under the steering gear.

[0013] Furthermore, a rack engaged with the steering gear is provided on the locking tongue.

[0014] Furthermore, a mating chute is provided in the slider control assembly on the side of the locking tongue, and the mating slider slides in the mating chute.

[0015] Beneficial effects

[0016] Adopting the technical solution provided by the present utility model, compared with the prior art, it has the following beneficial effects:

[0017] The technical solution provided by the present utility model realizes that after the stamping action is completed, when the seal rises, it will no longer rise at a relatively fast speed, and it will no longer stop rising after colliding with the top of the stamping machine by setting a rebound buffer structure. By setting the rebound buffer structure, as the seal rises, the rising speed of the seal can be gradually reduced, thereby greatly reducing the speed of the seal above the stamping machine, weakening the collision force, and protecting the stamping machine.

[0024] To make the technical solution of the present utility model clearer, the following further describes the present utility model in detail with reference to the accompanying drawings and specific embodiments.

[0025] Embodiment 1

[0026] Combined with the attached Figure 1-6, A pressing and rebounding buffer structure for a stamping machine, which is mainly applied to a stamping machine. The pressing and rebounding buffer structure can be directly set on the existing stamping machine structure. The stamping machine with the pressing and rebounding buffer structure includes a housing 10. Inside the housing 10, there is a slider control assembly 11. The bottom of the slider control assembly 11 is connected to a stamp fixture 12. A stamp 13 is installed inside the stamp fixture 12. A housing slide bar 14 is slidably arranged on the outside of the housing 10. The housing slide bar 14 cooperates with the slider control assembly 11. When using the stamping machine, by pulling down the housing slide bar 14, the housing slide bar 14 is inserted and cooperated with the slider control assembly 11, so as to drive the slider control assembly 11 to descend. After the slider control assembly 11 descends, it drives the stamp fixture 12 to descend. When the stamp fixture 12 descends, the stamp fixture 12 descends to drive the stamp 13 to descend. At this time, the stamp 13 realizes the stamping work.

[0027] In the existing stamping machine, the slider control assembly 11 of the stamping machine includes a servo motor 20. A gear 21 is rotatably arranged at the bottom of the servo motor 20. The servo motor 20 controls the rotation of the gear 21. The slider control assembly 11 is provided with a mounting bracket 22. A locking tongue 23 is slidably arranged inside the mounting bracket 22. The locking tongues 23 are preferably two symmetrically arranged ones, and both sides of each locking tongue 23 are also symmetrically structured. A top pin 24 is fixed on both sides of each locking tongue 23. There is a certain space between the two symmetrically arranged locking tongues 23. The space between the symmetrically arranged locking tongues 23 is used to accommodate the gear 21. On the opposite sides of the two symmetrically arranged locking tongues 23 facing each other, racks 25 are symmetrically arranged. The racks 25 are engaged with the gear 21.

[0028] After the gear 21 is engaged with the rack 25, the rotation of the gear 21 can drive the locking tongue 23 to slide inside the mounting bracket 22 through the rack 25. By the forward and reverse rotation of the gear 21, one side of the two symmetrically arranged locking tongues 23 can extend out of the mounting bracket 22, or retract from the state of extending out of the mounting bracket 22 back into the mounting bracket 22.

[0029] On the housing slide bar 14 of the stamping machine, there is a mating block 30 that moves inside the housing 10 of the stamping machine. The mating block 30 located inside the stamping machine 10 is arranged on both sides of the top pins 24 provided on the symmetrically arranged locking tongues 23. The mating block 30 is correspondingly arranged with the top pins 24. The mating block 30 is provided with a through hole 31. When the locking tongue 23 slides, the locking tongue 23 slides to drive the top pin 24 to slide outwards to both sides and extend out of the mounting bracket 22. The top pin 24 extending out of the mounting bracket 22 is inserted into the through hole 31 on the mating block 30. At this time, the cooperation between the top pin 24 and the mating block 30 of the housing slide bar 14 is completed.

[0030] At the same time, since the mating block 30 and the housing slide bar 14 are of an integral structure, a through sliding groove 18 for fixing and connecting the mating block 30 and the housing slide bar 14 and allowing partial sliding is provided on the housing 10 of the stamping machine.

[0031] Through the above technical solution, when the user needs to stamp, first, the servo 20 drives the gear 21 to rotate. The rotation of the gear 21 drives the lock tongue 23 to slide to both sides through the cooperation of the gear 21 and the rack 25. At this time, the top pin 24 on the lock tongue 23 is inserted into the perforation 31 of the mating block 30. The user pulls down the outer shell slide bar 14, thereby driving the slider control assembly 11 to move downward as a whole through the top pin 24, thus completing the stamping action.

[0032] After stamping is completed, the servo is installed in reverse. At this time, the top pin 24 exits from the perforation 31 of the mating block 30, and the outer shell slide bar 14 is no longer locked with the slider control assembly 11. After the top pin 24 exits from the perforation 31, since a return spring is provided between the slider control assembly 11 in the existing stamping machine and the top of the stamping machine, the slider control assembly 11 will rise as a whole driven by the return spring. Since the return spring is connected when the top pin 24 suddenly exits from the perforation 31, the pulling force for the slider control assembly 11 to rise is relatively large, resulting in a relatively fast rising speed. As a result, the slider control assembly 11 collides with the upper-side components inside the stamping machine, and it is easy for some components of the top components of the stamping machine or the slider control assembly 11 to be damaged.

[0033] The pressing and rebounding buffer structure is directly arranged in the above structure, thereby slowing down the rising speed of the slider control assembly 11.

[0034] A rebounding buffer outer shell 40 is fixedly arranged inside the stamping machine housing 10. The rebounding buffer outer shell 40 is a vertical structure up and down. The rebounding buffer outer shell 40 starts from the initial position at the top of the slider control assembly 11 and extends to the limit position at the bottom when the slider control assembly 11 moves to the bottom.

[0035] An opening is provided on one side of the rebounding buffer outer shell 40, and the opening faces the direction of the slider control assembly 11. A rebounding buffer slider 41 is slidably arranged inside the rebounding buffer outer shell 40. The top and bottom of the rebounding buffer outer shell 40 are respectively provided with a top cover and a bottom cover for closing the rebounding buffer outer shell. A rebounding buffer spring 43 is provided between the top cover of the rebounding buffer outer shell 40 and the rebounding buffer slider 41. The rebounding buffer spring 43 will provide an increased elastic force for the component when the rebounding buffer slider 41 slides upward, thereby slowing down the rising speed of the rebounding buffer slider 41.

[0036] A protruding block 42 is fixedly arranged on the side of the rebounding buffer slider 41 facing the opening of the rebounding buffer outer shell 40. The protruding block 42 extends out of the rebounding buffer outer shell 40 and moves along with the rebounding buffer slider 41.

[0037] A mating chute 50 is provided on the side of the lock tongue 23 close to the rebounding buffer outer shell 40 inside the slider control assembly 11. A mating slider 51 is slidably arranged inside the mating chute 50. One end of the mating slider 51 is fixed on the lock tongue 23, and the other end of the mating slider 51 is provided with a protrusion for mating with the protruding block 42.

[0038] The setting mode of the mating slider 51 needs to meet the requirement that when the locking tongue 23 drives the ejector pin 24 to extend outwards and penetrate into the through hole 31, the mating slider 51 at the end with the protrusion does not contact the protruding block 42. After the locking tongue 23 drives the ejector pin 24 to withdraw from the through hole 31, the mating slider 51 and the protruding block 42 overlap, the mating slider 51 and the protruding block 42 are in contact with each other up and down, and the end of the mating slider 51 with the protrusion is located below the protruding block 42.

[0039] Through the above technical solution, after the ejector pin 24 withdraws from the through hole 31, the return spring will drive the slider control assembly 11 to rise. At this time, the end of the mating slider 51 with the protrusion is located below the protruding block 42. Since the protruding block 42 is fixed on the resilient buffer slider 41, when the slider control assembly 11 pushes the resilient buffer slider 41 to rise, the resilient buffer spring 43 connected to the resilient buffer slider 41 will provide elastic force to slow down the rising speed of the resilient buffer slider 41, thereby further slowing down the rising speed of the slider control assembly 11.

[0040] The buffer component of the resilient buffer structure is not limited to a spring, and can be replaced by components with buffer functions such as a cylinder and an oil cylinder in other embodiments.

[0041] When the slider control assembly 11 is located above the stamping machine and a stamping operation needs to be performed, the locking tongue 23 drives the ejector pin 24 to insert into the through hole 31 under the drive of the steering gear 20. At this time, the end of the mating slider 51 with the protrusion no longer abuts against the protruding block 42 of the resilient buffer slider 41. The resilient buffer slider 41 slides to the bottom of the resilient buffer housing 40 under the elastic force of the resilient buffer spring 43. At the same time, the slider control assembly 11 can also move downward under the action of the housing slide bar 14 to complete the stamping operation.

[0042] The above embodiments only represent several implementation modes of the present invention, and the description is relatively specific and detailed, but it should not be construed as a limitation to the scope of the patent of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several deformations and improvements can still be made, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the patent of the present invention should be subject to the appended claims.
