Description

Technical Field

[0001] The utility model relates to the technical field of stamping dies, and particularly relates to a sprocket fine blanking die. Background Art

[0002] During the use of a sprocket die, hydraulic drive is often used to drive the upper die to stamp a steel plate on the lower die. The upper die is a punch, and the lower die is a die. The steel plate to be stamped is strip-shaped and sequentially passes through the processing area between the upper die and the lower die through an intermittently started conveyor belt. The steel plate is processed and formed by the cooperation of the punch and the die to obtain a preliminarily processed sprocket.

[0003] Among them, the patent with publication number CN214391860U discloses a sprocket stamping and blanking die, belonging to the technical field of die processing. It includes: a lower die; and an upper die arranged above the lower die and adapted to the lower die. Among them, the lower die includes: a bottom plate; a lower fixed block arranged on the top of the bottom plate; and a lower forming part arranged on the top of the lower fixed block. The upper die includes: a top plate; an upper fixed block arranged on the bottom of the top plate; and an upper forming part arranged on the upper fixed block. An elastic part is arranged on the top of the lower fixed block, and a moving block is arranged on the top of the elastic part. Among them, the moving block is slidably sleeved on the lower forming part. This application provides a sprocket stamping and blanking die, which can increase the bending angle of the surplus material around the steel plate when being stamped through the moving block sleeved on the forming part of the lower die and the spring installed at the bottom of the moving block, thereby improving the separation efficiency of the surplus material from the model and improving the quality of the sprocket.

[0004] During the use of this device, after the strip-shaped steel plate is stamped once, the stamped sprocket will stay inside the lower die. At this time, the sprocket needs to be taken out before the steel plate can be stamped again, which is inconvenient for continuous stamping of the steel plate, and thus reduces the production efficiency of the sprocket.

[0005] Therefore, it is very necessary to invent a sprocket fine blanking die to solve the above problems. Summary of the Utility Model

[0018] By adopting the above technical solution, during the process of the upper template descending, it drives the connecting plate and the push rod to move downward, pushing the sprocket that has not fallen off automatically downward, and pushing the formed sprocket into the interior of the aggregate box.

[0019] Optionally, on both the left and right sides of the upper surface of the lower template and at the upper right end position of the equipment bracket, there are fixedly connected support plates, and two groups of positioning columns are rotatably connected to the upper surfaces of the support plates.

[0020] By adopting the above technical solution, the support plates are used to support the steel plate for stamping, and the positioning columns limit the position of the steel plate.

[0021] Optionally, a punching block is fixedly connected to the lower end of the punching column.

[0022] By adopting the above technical solution, the punching block cooperates with the punching groove to punch the center of the sprocket.

[0034] In order to enable those skilled in the art to better understand the technical solution of the present utility model, the present utility model will be further introduced in detail below with reference to the accompanying drawings.

[0035] The present utility model provides a Figures 1 to 5 Shown sprocket fine blanking die, including an equipment support 1, a lower template 2 is fixedly connected to the upper side of the equipment support 1, an aggregate box 11 is fixedly connected to the right side of the equipment support 1, an upper template 3 is arranged on the upper side of the lower template 2, a blanking assembly is arranged between the lower template 2 and the upper template 3, the blanking assembly includes a stamping groove 25, a support block 26, a support ring 28, a support spring 29, a connecting plate 32 and a push rod 33, a hydraulic cylinder 31 is fixedly installed on the upper side of the upper template 3, a stamping plate 34 is fixedly connected to the middle position of the lower surface of the upper template 3, a stamping column 35 is fixedly connected to the middle position of the lower surface of the stamping plate 34, a punching block 36 is fixedly connected to the lower end of the stamping column 35, a bearing plate 23 is fixedly connected to the middle of the lower template 2, four groups of positioning holes 24 are opened on the surfaces of the lower template 2 and the bearing plate 23, a positioning rod 37 is fixedly connected to the lower surface of the stamping plate 34, and the positioning rod 37 is slidably connected with the positioning hole 24.

[0036] Among them, during the use process, the steel plate is placed between the upper template 3 and the lower template 2, and the steel plate is moved to the right by an intermittent conveyor belt. When the steel plate is in a static state, the hydraulic cylinder 31 pushes the upper template 3 downward, and cooperates with the stamping column 35 and the stamping groove 25 to punch the steel plate, shape the sprocket. After the sprocket stamping is completed, the support spring 29 and the support ring 28 cooperate to push the sprocket upward, and the sprocket is clamped into the punching hole on the surface of the steel plate. At this time, as the steel plate moves, it drives the sprocket to move to the right. When the sprocket passes above the aggregate box 11, the lower side of the sprocket lacks support, and at this time the sprocket will fall into the aggregate box 11, realizing automatic blanking of the sprocket and automatic collection of the formed sprocket, improving the production efficiency of the sprocket.

[0037] Refer to Figures 3 to 6 , the stamping groove 25 is opened in the middle position of the bearing plate 23. The support block 26 is fixedly connected to the middle position of the inner bottom wall of the stamping groove 25. An punching groove 27 is opened in the middle of the support block 26. The support ring 28 is slidably connected to the stamping groove 25. A plurality of support springs 29 are provided. The upper end of the support spring 29 is fixedly connected to the lower end of the support ring 28. The lower end of the support spring 29 is fixedly connected to the inner bottom wall of the stamping groove 25., the connecting plate 32 is fixedly connected to the right side of the upper template 3, the push rod 33 is fixedly connected to the lower surface of the connecting plate 32. On the left and right sides of the upper surface of the lower template 2 and at the upper right position of the equipment bracket 1, two sets of positioning columns 22 are rotatably connected to the upper surface of the support plate 21.

[0038] Specifically, the steel plate moves to the right on the surfaces of the three sets of support plates 21. At the same time, the positioning columns 22 on both sides position the two sides of the steel plate, improving the stability of the steel plate during the moving process and limiting the position of the steel plate, effectively improving the stamping accuracy of the sprocket.

[0039] In addition, during the process of the stamping column 35 stamping the surface of the steel plate, the sprocket is stamped into the stamping groove 25. At this time, the stamping column 35 cooperates with the sprocket to push the support ring 28 downward and squeeze a plurality of support springs 29. When the stamping column 35 moves upward, the plurality of support springs 29 will automatically push the sprocket upward, and then push the sprocket back into the punching hole on the surface of the steel plate. At this time, as the steel plate moves to the right, it drives the sprocket to move to the right. When the sprocket passes above the aggregate box 11, there is no support on the lower side of the sprocket, and at this time the sprocket will fall into the aggregate box 11.

[0040] At the same time, when the upper template 3 moves downward, it drives the connecting plate 32 to move downward, and then drives the push rod 33 to move downward. When the sprocket is relatively tightly connected to the steel plate and cannot fall off automatically, the push rod 33 pushes the sprocket downward and pushes the sprocket into the aggregate box 11 for collection.

[0041] The working principle of the present utility model: The formed sprocket is pushed upward by the support spring 29 through the support ring 28, and the sprocket is clamped into the punching hole on the surface of the steel plate. At this time, as the steel plate moves, it drives the sprocket to move to the right and transports the sprocket to the aggregate box 11, realizing automatic blanking of the sprocket and automatic collection of the formed sprocket, improving the production efficiency of the sprocket; at the same time, the three sets of support plates 21 support the steel plate, and the positioning columns 22 limit the positions of both sides of the steel plate, improving the stability of the steel plate during the moving process and maintaining the accuracy of sprocket stamping.

[0042] The above has shown and described the basic principles, main features and advantages of the present utility model. Those skilled in the art should understand that the present utility model is not limited by the above embodiments. The above embodiments and the descriptions in the specification are only preferred examples of the present utility model and are not used to limit the present utility model.
