Description

Technical Field

[0001] This utility model relates to the field of metal product processing technology, specifically a stamping machine for metal product processing. Background Technology

[0002] The reference patent title is: A convenient stamping machine for metal product processing (Authorization Announcement No.: CN219944277U, Authorization Announcement Date: 2023.11.03). It includes a stamping table and support legs. The support legs are fixedly installed around the bottom of the stamping table. A waste chip treatment device is provided on the top of the stamping table. A cleaning unit is located on the left side of the top of the stamping table. A stamping device is provided on the top of the stamping table. This convenient stamping machine for metal product processing, by setting up a waste chip treatment device, uses a spring to push the bottom plate out of the mold, and then a fan blows off the waste chips on the surface of the bottom plate, thereby preventing the waste chips from scratching the next stamped part and facilitating the removal of the stamped part. This solves the problem mentioned in the background art where waste chips generated during stamping remain in the support after the stamping machine stamps the part, and if the waste chips are not treated in time, they will scratch the surface of the next stamped part. The stamping device facilitates the stamping of parts, and the structure is simple and easy to use.

[0003] Based on the above-mentioned document: In the process of metal product processing, stamping machines are one of the commonly used equipment. After the traditional stamping machine completes the stamping action, the metal product is often left in the stamping groove. Due to the possible friction between the metal product and the stamping groove during the stamping process, and the possibility that the metal product may be tightly attached to the stamping groove after stamping deformation, it is difficult to unload the material. At present, the method of manually removing the metal product is inefficient, and the temperature of the stamped metal product is high, which poses certain safety hazards. Therefore, this utility model provides a stamping machine for metal product processing. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a stamping machine for metal product processing, which solves the problem that most existing stamping machines for metal product processing do not have a demolding structure, and that metal products tend to remain in the stamping groove after stamping, making them difficult to remove.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a stamping machine for metal product processing, comprising a processing table, a support plate fixedly connected to the top of the processing table, a stamping assembly on the top of the support plate, a pushing assembly on the rear side of the support plate, a stamping table mounted on the top of the processing table, and an ejector mechanism inside the stamping table, the ejector mechanism comprising:

[0014] Beneficial effects

[0015] This utility model provides a stamping machine for processing metal products. Compared with the prior art, it has the following advantages:

[0016] 1. This metal product processing stamping machine, by moving the control lever to rotate the control block, compresses the control spring, causing the control block to separate from the ratchet surface. At this time, without the limit of the control block, the top spring begins to reset, causing the sliding plate, top plate, and sliding toothed plate to slide upward synchronously. The cooled metal product is pushed out of the stamping groove by the top plate. During this process, the sliding of the sliding toothed plate will drive the linkage gear, linkage rod, and ratchet to rotate counterclockwise synchronously to reset. Finally, by activating the pusher cylinder, the pusher plate is driven to slide, pushing the metal product out through the pusher plate, realizing a rapid unloading operation. By setting up the top plate, the stamped metal product can be quickly and effectively removed from the stamping groove, avoiding burns to the hands caused by the high temperature of the metal product when manually handling it. At the same time, in conjunction with the pusher assembly, the rapid unloading of metal products can be achieved, greatly improving work efficiency.

[0017] 2. This metal product processing stamping machine, by configuring an auxiliary positioning component in the stamping assembly, can use a positioning plate to assist in positioning the metal material during the stamping operation of the stamping die, thereby maintaining the stability of the metal material during the stamping process and improving the quality of the finished metal products.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figure 1-5 This utility model provides a technical solution:

[0026] A stamping machine for processing metal products includes a processing table 1, a support plate 2 fixedly connected to the top of the processing table 1, a stamping assembly 3 on the top of the support plate 2, a pushing assembly 4 on the rear side of the support plate 2, a stamping table 5 mounted on the top of the processing table 1, and a ejector mechanism 6 inside the stamping table 5. The ejector mechanism 6 includes:

[0027] The ejector assembly 61 includes a limiting rod 611 installed at the bottom of the inner cavity of the stamping table 5. A sliding plate 612 is slidably connected to the surface of the limiting rod 611. An ejector plate 613 is fixedly connected to the top of the sliding plate 612. The surface of the ejector plate 613 is slidably connected to the interior of the stamping table 5. An ejector spring 614 is fixedly connected to the bottom of the sliding plate 612. One end of the ejector spring 614 is fixedly connected to the bottom of the inner cavity of the stamping table 5. A sliding toothed plate 615 is fixedly connected to the bottom of the sliding plate 612.

[0028] Linkage component 62 is installed inside processing table 1;

[0029] The control component 63 is located inside the processing table 1.

[0030] The rear side of the stamping table 5 is equipped with a symmetrical cooling medium outlet and a cooling medium inlet. By connecting with an external cooling device, a cooling cycle is formed, which can accelerate the rapid cooling of metal products in the stamping groove at the top of the stamping table 5.

[0031] The limiting rod 611 is used to limit the sliding of the sliding plate 612.

[0032] Preferably, the linkage assembly 62 includes a linkage rod 621 rotatably installed inside the processing table 1. One end of the linkage rod 621 is fixedly connected to a linkage gear 622. The surface of the linkage gear 622 meshes with the surface of the sliding toothed plate 615. A ratchet 623 is fixedly connected to the surface of the linkage rod 621.

[0033] Preferably, the control assembly 63 includes a control rod 631 rotatably mounted on the inner wall of the processing table 1. One end of the control rod 631 extends through to the top of the processing table 1, and the other end of the control rod 631 is fixedly connected to a control block 632. A control spring 633 is fixedly connected to the surface of the control block 632. One end of the control spring 633 is fixedly connected to the inner wall of the processing table 1, and one end of the control block 632 is in contact with the surface of the ratchet 623.

[0034] When the control spring 633 is not affected by external force, one end of the control block 632 will always be engaged with the surface of the ratchet 623; the top of the processing table 1 is provided with a sliding groove for the control rod 631 to slide.

[0035] Preferably, the pushing assembly 4 includes a pushing cylinder 41 installed on the rear side of the support plate 2. A pushing plate 42 is fixedly connected to one side of the pushing cylinder 41 via a piston rod. A connecting rod 43 is fixedly connected to one side of the pushing plate 42. The surface of the connecting rod 43 is slidably connected to the interior of the support plate 2.

[0036] The pusher cylinder 41 is connected to an external air source through an air pipe; the connecting rod 43 is used to slide and limit the pusher plate 42.

[0037] With the top material mechanism 6, the top material plate 613 can quickly and effectively remove the stamped metal products from the stamping groove, avoiding burns to the hands caused by the high temperature of the metal products when manually handling them. At the same time, in conjunction with the pusher assembly 4, the metal products can be quickly discharged, greatly improving work efficiency.

[0038] Preferably, the stamping assembly 3 includes a stamping cylinder 31 mounted on the top of the support plate 2. The bottom of the stamping cylinder 31 is fixedly connected to a stamping plate 32 via a piston rod. A stamping die 33 is mounted on the bottom of the stamping plate 32. An auxiliary positioning assembly 34 is provided inside the stamping plate 32.

[0039] The stamping cylinder 31 is connected to an external air source through an air pipe.

[0040] Preferably, the auxiliary positioning assembly 34 includes a positioning rod 341 that is slidably installed inside the stamping plate 32. The bottom end of the positioning rod 341 is fixedly connected to a positioning plate 342, and the top of the positioning plate 342 is fixedly connected to a buffer spring 343. One end of the buffer spring 343 is fixedly connected to the bottom of the stamping plate 32.

[0041] By configuring an auxiliary positioning component 34 in the stamping assembly 3, the positioning plate 342 can be used to assist in positioning the metal material during the stamping operation of the stamping die 33, thereby maintaining the stability of the metal material during the stamping process and improving the finished quality of the metal products.

[0042] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0043] During operation, the metal material is first placed on the surface of the stamping table 5. Then, by activating the stamping cylinder 31, the stamping plate 32, stamping die 33, and auxiliary positioning assembly 34 slide downwards simultaneously. At this time, the positioning plate 342 will first contact the metal material, pressing the metal material down onto the top of the stamping table 5. After the positioning plate 342 contacts the metal material, the positioning rod 341 will slide inside the stamping plate 32, compressing the buffer spring 343. Subsequently, the stamping die 33 and the stamping groove on the top of the stamping table 5 are pressed down. To achieve the stamping operation of metal materials, during the stamping process, the stamping die 33 pushes the ejector plate 613, sliding plate 612, and sliding toothed plate 615 to slide downwards simultaneously. This causes the sliding plate 612 to slide on the surface of the limit rod 611, compressing the ejector spring 614. The sliding of the sliding toothed plate 615 causes the linkage gear 622, linkage rod 621, and ratchet 623 to rotate clockwise simultaneously. The clockwise rotation of the ratchet 623 causes one end of the control block 632 to roll on the surface of the ratchet 623. After the stamping is completed, at this time... When the ratchet 623 is limited by the control block 632, the finished metal product will be located inside the stamping groove. At this time, the external cooling medium circulation can cool down the stamping table 5 and the metal product inside, preventing the metal product from being in a high-temperature state for a long time, which may cause changes in the metallographic structure of the material, thereby reducing the mechanical properties such as strength, hardness, and toughness of the material. Subsequently, by moving the control lever 631, the control block 632 is rotated, which compresses the control spring 633, and the surfaces of the control block 632 and the ratchet 623 are closed. Separation occurs when the control block 632 is not in use, causing the top spring 614 to reset, which in turn causes the sliding plate 612, the top plate 613, and the sliding toothed plate 615 to slide upwards synchronously. The cooled metal product is pushed out of the stamping groove by the top plate 613. During this process, the sliding of the sliding toothed plate 615 will drive the linkage gear 622, the linkage rod 621, and the ratchet 623 to rotate counterclockwise synchronously to reset. Finally, the pusher cylinder 41 is activated to drive the pusher plate 42 to slide, and the metal product is pushed out by the pusher plate 42, realizing a rapid discharge operation.
