DETAILED DESCRIPTION

[0033] ​​​​With reference to the drawings of the embodiments of the present application, the technical solutions in the embodiments of the present application will be clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments of the present application, all the other embodiments obtained by a person of ordinary skill in the art without creative work fall within the scope of the present application.

[0034] Please refer to Figures 1-10 The embodiment discloses a high-speed stamping mechanism for a full-electric servo press, which comprises a box body 1 and further comprises:

[0035] The driving mechanism comprises a motor 3 fixedly installed on the top inner wall of the box body 1, a screw rod 4 installed on the output shaft of the motor 3, a sliding plate 5 and a stamping column 6 threadedly installed on the outer surface of the screw rod 4, the stamping column 6 fixedly installed on the bottom of the sliding plate 5, and a one-way groove 7 formed on the outer surface of the stamping column 6;

[0036] The pressurizing mechanism comprises a telescopic rod 10, a pressurizing sleeve 20, a sliding ring 11 installed on the telescopic end of the telescopic rod 10, a plurality of groups of hinged blocks one 14 slidingly installed on the inner wall of the sliding ring 11, a fixed cylinder 15 hingedly connected in the hinged blocks one 14, a spring one 16 and a telescopic column 17 movably sleeved in the fixed cylinder 15, a plurality of groups of stroke columns 9 arranged on the inner wall of the box body 1, a hinged block two 18 hingedly connected at one end of the telescopic column 17, the hinged block two 18 fixedly connected with the pressurizing sleeve 20, a containing groove 22 formed on the inner wall of the pressurizing sleeve 20, a clamping block 24 and a spring two 23 movably clamped in the containing groove 22, and a fixed block 25 fixedly connected on the outer surface of the stamping column 6;

[0037] The device is optimized, and the pressurizing mechanism is designed to realize the stamping pressure of the stamping column 6 without increasing the power of the motor 3. A plurality of groups of articulated blocks one 14, fixed cylinders 15, springs one 16, telescopic columns 17 and articulated blocks two 18 are slidably installed in the sliding ring 11. A plurality of groups of articulated blocks two 18 are connected to a group of pressurizing sleeves 20. Under the initial condition, the sliding ring 11 is driven to move up and down by the telescopic rod 10, so that the sliding ring 11 can drive the articulated block one 14 to move up and down along the outer surface of the stroke column 9 through the adapter cylinder 12 and the adapter column 13. Since the stroke column 9 is inclined, it is inserted and adapted with the articulated block one 14, so that the articulated block one 14 changes the distance between the fixed cylinder 15 and the telescopic column 17 when moving up and down with the sliding ring 11, and changes the compression degree of the spring one 16. The pressurizing sleeve 20 is driven to accumulate elastic potential energy for subsequent pressurization. During the movement of the stamping column 6 downward, the pressurizing sleeve 20 is pushed downward by the fixed block 25, so that the pressurizing sleeve 20 moves downward and drives the articulated block two 18 and the telescopic column 17 to rotate downward. The clamping block 24 and the one-way slot 7 are connected in one direction, and the elastic force generated by the compression of the spring one 16 is fully applied to the stamping column 6, so that the device can meet the requirements of different stamping pressures and has strong applicability.

[0038] Wherein the inside of the box body 1 is also fixedly installed with a plurality of guide columns 2, and the outer surface of the sliding plate 5 and the inner side of the sliding ring 11 are fixedly installed with a plurality of guide plates, and the guide plates are adapted and connected to the outer surface of the guide column 2;

[0039] The guide column 2 is responsible for providing a guide function for the movement of the sliding plate 5 and the sliding ring 11, so that the movement of the sliding plate 5 and the sliding ring 11 is more stable.

[0040] Wherein the number of fixed blocks 25 is two, and the two fixed blocks 25 are symmetrically distributed on the front and rear sides of the outer surface of the stamping column 6 and located above the pressurizing sleeve 20;

[0041] This device, by incorporating a pressure-increasing sleeve 20 and a receiving groove 22 and a locking block 24 on the inner wall of the pressure-increasing sleeve 20, prevents horizontal pressure from being generated between the pressure-increasing sleeve 20 and the stamping column 6, thus reducing wear on the surface of the stamping column 6. It is equipped with four sets of fixed cylinders 15, a spring 16, a telescopic column 17, and a hinge block 18, with the pressure-increasing sleeve 20 and the telescopic column 17 hinged together by the hinge block 18. Pressure is applied to the stamping column 6 only when the axes of the fixed cylinders 15 and the telescopic column 17 are tilted downwards. The one-way groove 7 and the locking block 24 further enhance the pressure. The adapter snaps in place so that when the stamping column 6 moves downward, it drives the inner wall of the one-way groove 7 to slide against the inclined surface of the locking block 24, thereby pushing the locking block 24 horizontally into the receiving groove 22. It cannot drive the pressure sleeve 20 to move downward as a whole. Only when the fixing block 25 moves above the pressure sleeve 20 will it drive the pressure sleeve 20 to move downward. The four sets of springs 16 are distributed in pairs to completely offset the horizontal pressure generated on the stamping column 6 when the springs 16 are compressed, thereby greatly reducing the radial force on the stamping column 6 and the wear caused by the force.

[0042] The number of fixed cylinders 15 is four sets, and the four sets of fixed cylinders 15 are distributed equidistantly in a circle on the outside of the pressure-boosting sleeve 20.

[0043] like Figure 5 As shown, the four sets of fixed cylinders 15 are equidistantly distributed in a circle, thus providing a centripetal guiding function for the movement of the pressure sleeve 20. The spring 16 and telescopic column 17, which are sleeved and installed inside the fixed cylinder 15, are connected to the pressure sleeve 20 in the same way and with the same compression stroke, so that the pressure sleeve 20 can maintain zero net force in the horizontal direction, that is, it can ensure that the pressure sleeve 20 can always maintain stable movement on its own axis.

[0044] Among them, multiple sets of adapter cylinders 12 are fixedly installed on the inner side of the slip ring 11, and an adapter post 13 is movably sleeved inside the adapter cylinder 12. One end of the outer side of the adapter post 13 is fixedly connected to the hinge block 14.

[0045] like Figure 1 As shown, when the telescopic rod 10 drives the slip ring 11, the adapter cylinder 12 and the adapter column 13 to move up and down, it will drive the hinge block 14 to move back and forth along the axis of the stroke column 9. Since the axis of the stroke column 9 is inclined, the hinge block 14 will move back and forth in the horizontal direction. At this time, the adapter column 13 and the adapter cylinder 12 can provide horizontal displacement support.

[0046] Among them, the inner wall of the housing 1 is fixedly connected to multiple sets of fixing plates 8, and the two ends of the stroke column 9 are fixedly connected to the fixing plates 8 respectively. The hinge block 14 has a sliding groove 21 inside, and the stroke column 9 is adapted to be inserted into the inner wall of the sliding groove 21.

[0047] Each set of fixed plate 8 is set to two, and are fixedly connected in the inside of the box 1, the purpose is to provide fixed support for the stroke column 9 of the inclined design.

[0048] Wherein, the stroke column 9 is inclined distribution with the top end close to the axis of the punch column 6 and the bottom end away from the axis of the punch column 6, the axis of the fixed cylinder 15 and the telescopic column 17 is in the horizontal state under the initial condition;

[0049] The stroke column 9 of the inclined design is inserted into the hinge block 14, so that the hinge block 14 can drive the hinge block 14 and the fixed cylinder 15 to change the compression degree of the spring 16 and the pressure of the punch column 6 during the up and down movement.

[0050] Wherein, the two ends of the spring 16 are respectively elastically connected with the fixed cylinder 15 and the telescopic column 17, and the spring 16 is compressed and arranged on the inner wall of the fixed cylinder 15;

[0051] The spring 16 is compressed into the inside of the fixed cylinder 15, which exerts pressure on the telescopic column 17 and transmits the pressure to the pressure sleeve 20, and the pressure is transmitted to the punch column 6 through the clamping block 24 installed on the inner wall of the guide column 2 and the one-way groove 7.

[0052] Wherein, the outer surface of the pressure sleeve 20 is fixedly installed with a plurality of limiting plates 19 located below the hinge block 18, and the bottom of the hinge block 18 abuts against the limiting plate 19;

[0053] The device further comprises a limiting plate 19 fixedly installed on the outer surface of the pressure sleeve 20 below the hinge block 18, and the bottom of the hinge block 18 abuts against the limiting plate 19. When the punch column 6 moves upward and drives the pressure sleeve 20 to reset, the limiting plate 19 can drive the telescopic column 17, the fixed cylinder 15 and the hinge block 14 to move upward by the abutting limiting action of the hinge block 18. At this time, the spring 16, the fixed cylinder 15 and the telescopic column 17 are reset in the horizontal state, and the spring force generated by the compression of the spring 16 does not generate vertical downward component force, so that the motor 3 does not increase additional power, thereby effectively reducing the wear of the motor 3.

[0054] Wherein, the one-way groove 7 is provided with a plurality of groups and is vertically and equidistantly distributed along the left and right sides of the outer surface of the punch column 6, the clamping block 24 is provided with a slope on the side facing the inner wall of the one-way groove 7, and the clamping block 24 is adapted to abut against the one-way groove 7, and the two ends of the spring 23 are respectively elastically connected with the clamping block 24 and the accommodating groove 22;

[0055] The one-way groove 7 cooperates with the clamping block 24, so that the pressure sleeve 20 is clamped in the inner wall of the one-way groove 7 by the clamping block 24 after being driven downward by the fixed block 25, and the downward extrusion of the punch column 6 is generated.

[0056] Working principle:

[0057] When the device is working, first, the telescopic rod 10 is started, and the sliding ring 11, the fixed cylinder 15, and the telescopic column 17 are moved, so that the telescopic column 17 rotates around the axis of the hinge block two 18 until the bottom of the hinge block two 18 abuts against the bottom of the limiting plate 19. At this time, the axes of the fixed cylinder 15 and the telescopic column 17 are horizontal, the spring one 16 is compressed by the telescopic column 17, and the rebound forces generated by the four groups of spring one 16 cancel each other out.

[0058] Then, the motor 3 is started and the screw rod 4 is rotated to drive the sliding plate 5 and the stamping column 6 to move downward, as shown in the figure. Figure 3 The downward moving stamping column 6 drives the inclined surface of the inner wall of the one-way groove 7 to slide and abut against the upper inclined surface of the clamping block 24, and pushes the clamping block 24 horizontally to the inner wall of the accommodating groove 22 to compress the spring two 23. At this time, the pressure-increasing sleeve 20 remains in the original position and does not move until the fixed block 25 moves to the position abutting against the pressure-increasing sleeve 20, and then starts to move downward to drive the pressure-increasing sleeve 20. At this time, the hinge block two 18, the telescopic column 17, and the fixed cylinder 15 are driven to rotate downward around the axis of the hinge block one 14. At this time, the elastic potential energy of the spring one 16 being compressed is released, and the horizontal component of force of the four groups of spring one 16 is canceled out under the action of the four groups of telescopic column 17, and the vertical component of force is downward through the pressure-increasing sleeve 20 and acts on the upper surface of the stamping column 6, as shown in the figure. Figure 3 When the pressure-increasing sleeve 20 moves downward, the clamping block 24 is clamped into the inner wall of the one-way groove 7 and is tightly connected with the stamping column 6. When the stamping column 6 moves downward, the downward stamping pressure is greatly strengthened.

[0059] Finally, after the one-way groove 7 completes the stamping action, it is ready to reset. At this time, the telescopic rod 10 is started, and the sliding ring 11 and the adaptive cylinder 12 are moved downward to drive the adaptive column 13, the hinge block one 14, and the fixed cylinder 15 to move downward. At this time, the fixed cylinder 15 starts to adapt to rotate between the hinge block two 18 and the hinge block one 14. The movement trajectory of the hinge block one 14 is inclined downward along the axis of the stroke column 9 during the downward movement, and the distance between the fixed cylinder 15 and the telescopic column 17 is pulled apart. At this time, the spring one 16 is stretched, and the rebound force generated by the spring one 16 is reduced. When the hinge block one 14 moves downward to the position where the axes of the fixed cylinder 15 and the telescopic column 17 are both horizontal, the spring one 16 and the pressure-increasing sleeve 20 no longer generate downward pressure on the stamping column 6. At this time, the telescopic rod 10 is controlled to move upward, the motor 3 is reversed, and the sliding plate 5 and the stamping column 6 are moved upward, so that the upward movement speed of the sliding ring 11 is the same as that of the stamping column 6. Finally, the device is reset.

[0060] It should be noted that the above examples are only used to illustrate the technical solutions of the present application but not limit the present application. Although the present application is described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present application can be modified or equivalently replaced, without departing from the spirit and scope of the technical solutions of the present application, which should be covered in the scope of the claims of the present application.
