A continuous stamping die

Abstract

This application discloses a continuous stamping die, belonging to the field of stamping die technology. It includes a worktable with support legs fixedly connected to its bottom and a mounting plate fixedly connected to its upper end. A stamping assembly is mounted on the outer wall of the mounting plate. The stamping assembly includes a motor, which is fixedly connected to the outer wall of the mounting plate. This application, by setting the stamping assembly to include a motor, connecting rod A, connecting rod B, and a moving plate, ensures stable and precise stamping action through a mechanical transmission system driven by the motor. The motor's output shaft directly drives connecting rod A, and through the coordinated action of connecting rod B and the moving plate, the stamping plate achieves precise up-and-down movement control. When the moving plate presses down, the die can smoothly move to the bottom of the pressure plate for stamping, and when the moving rod rises, the die automatically returns to its original position. Reversing the motor's direction allows the die on the other side to perform the same operation. This dual-die structure significantly improves production efficiency.

Description

Technical Field

[0001] This application relates to the field of stamping die technology, and more specifically, to a continuous stamping die. Background Technology

[0002] Stamping dies are special process equipment used in cold stamping to process materials (metal or non-metal) into parts (or semi-finished products).

[0003] Patent document CN222519737U discloses a continuous stamping die, relating to the field of die equipment technology. It includes a base with a stamping groove at one end of its top. A gear at the output of a motor drives a hollow gear on one side. The rotation of the hollow gear moves a threaded rod, causing the fixing brackets at both ends of the threaded rod to move to the left. At this time, a vacuum pump on the right side is activated to fix the shaped sheet metal. Simultaneously, the vacuum pump on the left side fixes the sheet metal. The threaded rod then moves the fixing brackets to the right again, and both vacuum pumps are closed. The sheet metal fixed by the left vacuum pump falls onto the feeding platform, while the shaped sheet metal fixed by the right vacuum pump falls into the placement frame.

[0004] The aforementioned application document addresses the problem that, during the use of traditional stamping dies, the shaped sheet metal varies in shape after stamping, making it difficult to remove the sheet metal mechanically. This necessitates manual removal of the shaped sheet metal from the forming groove. However, this requires placing a new sheet metal for stamping after the shaped sheet metal has been removed, which is not conducive to improving stamping efficiency.

[0005] Therefore, a continuous stamping die is provided. Utility Model Content

[0006] To address the shortcomings of existing technologies, this utility model provides a continuous stamping die, solving the problems mentioned in the background section. To achieve the above objectives, this utility model is implemented through the following technical solution: A continuous stamping die includes a worktable, with a support leg fixedly connected to the bottom of the worktable, and a mounting plate fixedly connected to the upper end of the worktable. A stamping assembly is mounted on the outer wall of the mounting plate. The stamping assembly includes a motor, which is fixedly connected to the outer wall of the mounting plate. The output shaft of the motor passes through the mounting plate and is fixedly connected to a connecting rod A. The other end of connecting rod A is hinged to a connecting rod B. A moving plate is hinged to the bottom of connecting rod B. A pressure plate and a moving rod are fixedly connected to the bottom of the moving plate. A rotating cylinder is rotatably connected to the upper end of the worktable. A guide groove is formed on the outer wall of the moving rod. A sliding shaft is fixedly connected to the inner wall of the rotating cylinder. A gear is fixedly sleeved on the outer wall of the rotating cylinder. A toothed plate meshes with the side of the gear. A die is fixedly connected to the outer wall of the toothed plate.

[0007] Preferably, the mounting plate has a groove on its inner side, and one end of the movable plate is slidably connected inside the groove.

[0008] Preferably, the upper end of the workbench has a through hole, through which the moving rod moves movably.

[0009] Preferably, the sliding shaft is slidably connected inside the guide groove, and the toothed plate is slidably connected to the upper end of the worktable.

[0010] Preferably, the upper end of the workbench is equipped with a stripping assembly, which includes a cylinder. The output end of the cylinder is fixedly connected to a connecting block, and the side of the connecting block is fixedly connected to a hydraulic chamber. Hydraulic rods A and B are slidably connected inside the two ports of the hydraulic chamber.

[0011] Preferably, the upper end of the workbench is provided with a movable groove, and the hydraulic chamber is slidably connected inside the movable groove.

[0012] Preferably, the upper end of the worktable and the interior of the mold are respectively provided with through groove A and through groove B.

[0013] The advantages of this application are:

[0014] I. This application, by setting up a stamping assembly including a motor, connecting rod A, connecting rod B, and a moving plate, ensures stable and precise stamping action through a mechanical transmission system driven by the motor. The motor's output shaft directly drives connecting rod A, and through the coordinated action of connecting rod B and the moving plate, the stamping plate achieves precise up-and-down movement control. When the moving plate presses down, the die can smoothly move to the bottom of the pressure plate for stamping, and when the moving rod rises, the die automatically returns to its original position. After reversing the motor's drive, the die on the other side can perform the same operation. This dual-die structure greatly improves production efficiency.

[0015] Second, by setting up a stripping component, the workpiece in the mold can be pushed out in time after stamping through the cooperation of cylinder and hydraulic chamber, thus avoiding manual operation, improving the degree of automation, and reducing errors and inconvenience caused by manual intervention.

[0023] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are merely some, not all, of the embodiments of the present application. All other embodiments obtained by those skilled in the art based on the embodiments of the present application without creative effort should fall within the scope of protection of the present application.

[0024] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0025] Example 1

[0026] See Figures 1-4 This embodiment provides a continuous stamping die, including a worktable 1, a support leg 2 fixedly connected to the bottom of the worktable 1, a mounting plate 3 fixedly connected to the upper end of the worktable 1, and a stamping assembly 4 assembled on the outer wall of the mounting plate 3; the stamping assembly 4 includes a motor 41, the motor 41 is fixedly connected to the outer wall of the mounting plate 3, the output shaft of the motor 41 passes through the mounting plate 3 and is fixedly connected to a connecting rod A42, the other end of the connecting rod A42 is hinged to a connecting rod B43, the bottom of the connecting rod B43 is hinged to a moving plate 44, the bottom of the moving plate 44 is fixedly connected to a pressure plate 45 and a moving rod 47, the upper end of the worktable 1 is rotatably connected to a rotating cylinder 46, the outer wall of the moving rod 47 is provided with a guide groove 48, the inner wall of the rotating cylinder 46 is fixedly connected to a sliding shaft 49, the outer wall of the rotating cylinder 46 is fixedly fitted with a gear 413, the side of the gear 413 is meshed with a toothed plate 410, and the outer wall of the toothed plate 410 is fixedly connected to a die 411.

[0027] The inner side of the mounting plate 3 is provided with a sliding groove 412, and one end of the movable plate 44 is slidably connected to the inside of the sliding groove 412.

[0028] A through hole is provided at the upper end of the worktable 1, through which the moving rod 47 moves. The sliding shaft 49 is slidably connected inside the guide groove 48, and the toothed plate 410 is slidably connected to the upper end of the worktable 1.

[0029] In practical use, the plate to be stamped is first placed inside the mold 411. Then, the motor 41 is started so that it drives the connecting rod A42 to rotate through the output shaft. Then, the upper end of the connecting rod B43, which is hinged to the other end of the connecting rod A42, will rotate around the output shaft of the motor 41. Then, the bottom end of the connecting rod B43 will drive the moving plate 44 to move up and down inside the slide 412. Then, the moving rod 47 at the bottom of the moving plate 44 will also move accordingly.

[0030] When the moving rod 47 moves downward, the sliding shaft 49 on the inner wall of the rotating cylinder 46 is slidably connected to the inside of the guide groove 48 opened on the outer wall of the moving rod 47. Since the lower half of the guide groove 48 is spiral, the moving rod 47 will drive the rotating cylinder 46 to rotate a certain number of times through the sliding shaft 49 during the initial period of descent. As a result, the gear 413 fixedly sleeved on the outer wall of the rotating cylinder 46 will rotate, and the toothed plate 410 meshing with the gear 413 will move. This will drive the molds 411 on both sides of the toothed plate 410 to move. Thus, during the descent of the bottom pressure plate 45 of the moving plate 44, one side of the mold 411 can be moved to the bottom of the pressure plate 45, thereby realizing stamping.

[0031] Since the rear part of the guide groove 48 is straight, after the mold 411 moves to the bottom of the pressure plate 45, the mold 411 will not continue to move, while the pressure plate 45 can continue to descend for stamping.

[0032] When the moving rod 47 rises, the stamped die 411 can return to the side, and then its motor 41 can reverse to stamp the die 411 on the other side.

[0033] Example 2

[0034] See Figures 1-4 Based on Embodiment 1, a stripping assembly 5 is mounted on the upper end of the workbench 1. The stripping assembly 5 includes a cylinder 51, with a connecting block 52 fixedly connected to the output end of the cylinder 51. A hydraulic chamber 53 is fixedly connected to the side of the connecting block 52, and hydraulic rods A58 and B54 are slidably connected inside the two ports of the hydraulic chamber 53. A moving groove 55 is provided on the upper end of the workbench 1, and the hydraulic chamber 53 is slidably connected inside the moving groove 55. Through grooves A56 and B57 are respectively provided on the upper end of the workbench 1 and inside the mold 411.

[0035] In practical use, after the stamping is completed and the mold 411 returns to the side, the cylinder 51 is activated to drive the hydraulic chamber 53 to move closer to the mold 411 via the connecting block 52. When the mold 411 returns to the side, it will squeeze the hydraulic rod A58 to slide into the hydraulic chamber 53. Then, the hydraulic rod B54 at the other end of the hydraulic chamber 53 will move upward under the pressure transmitted by the hydraulic oil, so that it can pass through the through groove A56 and through groove B57 to push out the plate inside the mold 411.

[0036] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
