Abstract
Description
Technical Field
[0001] This utility model relates to the field of stamping technology, specifically a standard parts stamping device. Background Technology
[0002] In modern manufacturing, standard parts serve as fundamental components of industrial production, and their processing quality and production efficiency directly impact the performance and cost of products across various industries. As the core equipment for the mass production of standard parts, the structural design and functional integrity of stamping equipment are of paramount importance.
[0003] According to the search, the standard stamping device disclosed in CN 220942929 U uses a buffer assembly to protect the stamping equipment body from impact. During the stamping process, the impact force is transmitted through the die base and support plate to the buffer seat and damping plate. The two-stage buffering avoids equipment damage and solves the problem of wear caused by rigid impact of the lower die base to a certain extent.
[0004] However, this device focuses solely on equipment protection and completely lacks an automatic workpiece centering and correction function. In actual production, the workpiece needs to be precisely positioned in the center of the lower die holder to ensure stamping accuracy. However, after the workpiece is placed, the aforementioned device still requires manual adjustment due to the lack of a centering structure. This not only increases labor costs and operation time but also makes the workpiece positioning prone to deviation due to human error. Furthermore, during manual positioning, operators frequently need to approach the dangerous stamping area, posing a risk of mechanical injury.
[0005] Therefore, developing a standard part stamping device that integrates automatic workpiece correction and centering functions has become an urgent need to improve production efficiency and product quality. Utility Model Content

[0014] Compared with the prior art, the beneficial effects of this utility model are:
[0015] The correction component at the center of the lower mold base of this utility model is driven by a motor-driven bidirectional lead screw, which drives the movable parts to move synchronously in opposite directions. The telescopic correction rod on the top surface of the movable parts contacts the side wall of the workpiece and applies a horizontal thrust, automatically centering the workpiece to the center of the lower mold base.

[0024] The technical solution of this patent will be further described in detail below with reference to specific embodiments.
[0025] Example 1
[0026] Please see Figure 1-7A standard part stamping device includes a base 1, a lower die holder 2 fixedly mounted on the base 1, a support frame 3 fixedly mounted on the base 1, a lifting seat 5 mounted on the support frame 3 via a hydraulic cylinder 4, and an upper die holder 6 mounted on the bottom surface of the lifting seat 5. The lifting seat 5, driven by the hydraulic cylinder 4, drives the upper die holder 6 to complete the stamping action. A correction component is also provided at the center of the lower die holder 2. The correction component includes a bidirectional lead screw 8, a movable part 10, and a correction rod 11. A first slot 7 is formed at the center of the lower die holder 2. The bidirectional lead screw 8 is rotatably disposed within the first slot 7 and driven by a motor 9 located on the outer side of the lower die holder 2. 9 provides the rotational power for the bidirectional lead screw 8. Threaded bushings are symmetrically installed on the two threaded parts of the bidirectional lead screw 8. The threaded bushings are fixedly embedded in the movable part 10. The movable part 10 moves synchronously in opposite directions under the drive of the bidirectional lead screw 8 to achieve precise symmetrical adjustment. The movable part 10 is slidably set in the first strip groove 7, and multiple correction rods 11 are fixedly arranged side by side on the top surface of the movable part 10. The correction rods 11 are telescopic structures. The telescopic correction rods 11 can adapt to workpieces of different heights. Their ends contact the side wall of the workpiece and apply horizontal thrust to automatically center the workpiece to the center of the lower mold base 2, completely eliminating the error and safety risk of manual adjustment.
[0027] The first strip groove 7 has a sliding groove 12, and the bottom surface of the movable part 10 is fixedly provided with a slider 13 that is adapted to slide with the sliding groove 12. The sliding groove 12 and the slider 13 cooperate to constrain the movement trajectory of the movable part 10 and ensure the movement stability of the correction rod 11.
[0028] Example 2
[0029] This embodiment is an improvement on embodiment 1, specifically as follows:
[0030] Please see Figure 2 , Figure 4 , Figure 5 and Figure 7 The lower mold base 2 is symmetrically provided with second strip grooves 15 on both sides of the correction component. A top plate 14 is movably embedded in the second strip groove 15. The base 1 is also provided with a lifting component that drives the top plate 14 to move up and down. The lifting component drives the top plate 14 to move upward, which can lift the formed workpiece upward. The top plate 14 automatically ejects the workpiece under the drive of the lifting component, avoiding manual removal operation and improving safety and efficiency.
[0031] Specifically, the lifting assembly includes a sleeve 16, a telescopic rod 17, a first piston 18, and an infusion unit. The sleeve 16 is fixedly embedded in the base 1, and the first piston plate 18 is slidably and sealed inside the sleeve 16. The first piston plate 18 is connected to the top plate 14 via the telescopic rod 17, wherein the telescopic rod 17 transmits the linear movement of the first piston plate 18 to the top plate 14. The infusion unit is used to deliver fluid into the sleeve 16, wherein the fluid pressure pushes the first piston plate 18 upward, realizing the ejection action.
[0032] Preferably, the infusion unit includes infusion modules symmetrically arranged on the top surface of the lifting seat 5. The infusion module includes a piston cylinder 19, a push-pull rod 20, a piston rod 21, and a second piston 22. The piston cylinder 19 is fixedly installed on the top surface of the lifting seat 5. The piston cylinder 19 is connected to the sleeve 16 through an infusion tube. The piston rod 21 is symmetrically inserted into both ends of the piston cylinder 19. The second piston 22 is installed at one end of the piston rod 21 inside the piston cylinder 19, and a fixing block 23 is fixedly installed at the other end. A spring 24 is also sleeved on the rod of the piston rod 21 between the fixing block 23 and the piston cylinder 19. In normal condition, the spring 24 pushes the fixing block 23 away from the piston cylinder 19, so that the second piston 22 returns to its original position. The fixing block 23 is connected to the top surface of the support frame 3 through the push-pull rod 20. Both ends of the push-pull rod 20 are hinged. The push-pull rod 20 converts the up-and-down movement of the lifting seat 5 into the compression power of the piston cylinder 19, realizing a zero-extra-energy-consumption design for the linkage of pressing and ejection.
[0033] In addition, a horizontal plate 25 is fixedly installed on the top surface of the lifting seat 5. The horizontal plate 25 is located below the fixed block 23, and a track groove 26 is provided on the horizontal plate 25. A slide rail is provided on the bottom surface of the fixed block 23 to slide and adapt to the track groove 26. The track groove 26 and the slide rail cooperate to guide the fixed block 23 to move vertically, prevent the piston rod 21 from deflecting, and ensure the sealing reliability of the second piston 22.
[0034] Working principle:
[0035] After the workpiece is placed on the lower die base 2, the motor 9 is started to drive the bidirectional lead screw 8 to rotate, causing the two movable parts 10 on both sides to slide synchronously towards each other along the slide groove 12. The correction rod 11 contacts the side wall of the workpiece and pushes it to be precisely centered. After centering is completed, the hydraulic cylinder 4 drives the lifting seat 5 to move downward, and the upper die base 6 stamps the workpiece.
[0036] Meanwhile, the lifting seat 5 descends, pulling the fixed block 23 down along the track groove 26 of the horizontal plate 25 via the push-pull rod 20. The piston rod 21 and the second piston 22 are pulled outward under the action of the spring 24 and the push-pull rod 20. The second piston 22 forms a negative pressure in the piston cylinder 19, drawing back the fluid in the sleeve 16, keeping the top plate 14 in a low position to avoid the stamping. After the stamping is completed, the hydraulic cylinder 4 lifts the lifting seat 5, and the push-pull rod 20 pushes the fixed block 23 and the piston rod 21 to reset, which can transport the fluid in the piston cylinder 19 to the sleeve 16. The first piston plate 18 drives the telescopic rod 17 and the top plate 14 to reset upward. At this time, the top plate 14 smoothly pushes the formed workpiece upward, separating it from the lower mold base 2, which facilitates the unloading of the workpiece and completes the fully automatic correction, stamping and demolding process.

Those skilled in the art can fully implement it, so there is no need to elaborate. The content protected by this utility model does not involve any improvement to the internal structure and method.
[0038] It should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This way of describing the specification is only for clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
