Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of stamping dies, and particularly relates to a low-noise stamping die. Background Art
[0002] Stamping can be classified into two major categories according to the process: separation processes and forming processes. The separation process is also called blanking, and its purpose is to separate the stamping part from the sheet along a certain contour line while ensuring the quality requirements of the separation section. The purpose of the forming process is to plastically deform the sheet without damage to form a workpiece with the required shape and size.
[0003] Among them, the publication number CN216857924U discloses a low-noise stamping die, which relates to the field of dies. It includes a punch and a die. The end face of the punch close to the die is a blanking surface, and the end face of the die close to the punch is a contact surface. The contact surface is a horizontal plane, and the blanking surface is an inclined plane. In the stamping process of this application, the lowest point of the blanking surface first contacts the sheet, and then gradually increases the contact area, having the effect of low stamping noise.
[0004] During the use of this device, after the sheet is stamped, the waste will be stamped into the interior of the die. When the punch rises, the stripper plate will eject the waste upward. At this time, the waste will accumulate near the die. As the waste continuously falls, continuous noise will be generated, resulting in a low noise reduction effect of the stamping die. Moreover, the accumulated waste needs to be cleaned by the staff during downtime, resulting in a reduction in the operating efficiency of the equipment.
[0005] Therefore, it is very necessary to invent a low-noise stamping die to solve the above problems. Summary of the Utility Model
[0006] The purpose of the utility model is to provide a low-noise stamping die to solve the problems in the technology that continuous noise will be generated as the waste continuously falls, resulting in a low noise reduction effect of the stamping die, and the accumulated waste needs to be cleaned by the staff during downtime, resulting in a reduction in the operating efficiency of the equipment.
[0007] To achieve the above purpose, the utility model provides the following technical solution: A low-noise stamping die includes a bearing base. The upper surface of the bearing base is fixedly connected with a supporting die. A stripping mechanism is arranged inside the supporting die and the bearing base. The stripping mechanism includes a stamping chamber, a positioning rod, a support plate, a limiting block, a cylinder, an aggregate box, a connecting plate, a pushing plate and a pressing plate. A rubber gasket is fixedly connected to the right end of the pushing plate. The interior of the aggregate box is filled with sound insulation cotton. A stamping punch is arranged above the supporting die. A hydraulic cylinder is installed above the stamping punch. A processing plate is arranged between the stamping punch and the supporting die.
[0008] By adopting the above technical solution, the hydraulic cylinder pushes the stamping punch downward. The stamping punch and the supporting die cooperate to perform stamping on the processing plate. During the stamping process, the waste material and the supporting plate are pushed downward. At this time, the air cylinder pushes the connecting plate to the right side. The pressing plate fixes the position of the supporting plate. The pushing plate pushes the waste material to the right side, causing it to fall into the interior of the aggregate box. The aggregate box collects the waste material, preventing the waste material from scattering on the surface of the equipment. At the same time, the rubber gasket avoids generating noise during the material ejection process, and the sound insulation cotton prevents the sound of the waste material falling from spreading out, effectively reducing the noise during the stamping process.
[0009] Optionally, the stamping chamber is opened inside the pressure-bearing base. Two groups of positioning grooves are opened on the inner top wall of the stamping chamber. The positioning rod is slidably connected to the inside of the positioning groove. The supporting plate is fixedly connected to the upper and lower ends of the positioning rod.
[0010] By adopting the above technical solution, the positioning rod slides up and down inside the positioning groove, thereby driving the two groups of supporting plates to slide up and down inside the supporting die and the stamping chamber respectively.
[0011] Optionally, a limiting block is fixedly connected to the left side of the positioning rod, and a supporting spring is fixedly connected to the lower surface of the lower supporting plate. The lower end of the supporting spring is fixedly connected to the inner bottom wall of the stamping chamber.
[0012] By adopting the above technical solution, the supporting spring, the supporting plate and the positioning rod cooperate to support the lower end of the processing plate, improving the smoothness of the side of the punching hole and the stamping accuracy. During the process of the stamping punch pressing downward, the supporting plate and the positioning rod are pushed downward, squeezing the supporting spring. After the stamping punch is lifted, the supporting spring pushes the supporting plate and the positioning rod upward.
[0013] Optionally, the air cylinder is fixedly installed at the left side position on the upper surface of the pressure-bearing base. The output end of the air cylinder is fixedly connected to the connecting plate. Two groups of pushing plates are provided, and both groups of pushing plates are fixedly connected to the right side surface of the connecting plate.
[0014] Optionally, a connecting hole is opened in the middle of the connecting plate. A sliding rod is fixedly connected to the left end of the pressing plate. The sliding rod is slidably connected to the connecting hole.
[0015] By adopting the above technical solution, the air cylinder pushes the connecting plate to the right, thereby pushing the pushing plate and the pressing plate to the right.
[0016] Optionally, a limiting spring is sleeved on the surface of the sliding rod. The right end of the limiting spring is fixedly connected to the pressing plate, and the left end of the limiting spring is fixedly connected to the surface of the connecting plate.
[0017] By adopting the above technical solution, the sliding rod slides inside the connecting hole.
[0018] Optionally, a limiting groove is provided at the middle position of the left side surface of the supporting female die and at the left side position of the inner top wall of the stamping chamber. The limiting block is slidably connected to the limiting groove, and limiting holes are provided at the front and rear positions of the left side surface of the supporting female die.
[0019] By adopting the above technical solution, the limiting block slides inside the limiting groove.
[0020] Optionally, a discharge hole is provided on the right side surface of the supporting female die. The aggregate box is fixed at the right side position on the upper surface of the pressure-bearing base, and a feed hole is provided on the left side surface of the aggregate box.
[0021] By adopting the above technical solution, the waste is discharged into the interior of the aggregate box through the discharge hole and the feed hole.
[0022] In the above technical solution, the technical effects and advantages provided by the present utility model are as follows:
[0023] 1. During the stamping process of the present utility model, the waste and the support plate are pushed downward. At this time, the air cylinder pushes the connecting plate to the right side, the pressing plate fixes the position of the support plate, and the pushing plate pushes the waste to the right side, causing it to fall into the interior of the aggregate box. At the same time, the rubber gasket avoids generating noise during the material discharging process, and the sound insulation cotton avoids the sound of the waste falling from being transmitted out, effectively reducing the noise during the stamping process, and solving the problem that as the waste continuously falls, continuous noise will be generated, resulting in a low noise reduction effect of the stamping die.

[0033] In order to enable those skilled in the art to better understand the technical solutions of the present utility model, the present utility model will be further introduced in detail below in conjunction with the accompanying drawings.
[0034] The present utility model provides a Figures 1 to 4 low-noise stamping die as shown, including a pressure-bearing base 1. A support female die 2 is fixedly connected to the upper surface of the pressure-bearing base 1. A material discharging mechanism is arranged inside the support female die 2 and the pressure-bearing base 1. The material discharging mechanism includes a stamping chamber 11, a positioning rod 13, a support plate 14, a limiting block 15, a cylinder 17, an aggregate box 18, a connecting plate 3, a pusher plate 32 and a pressing plate 33. A rubber gasket is fixedly connected to the right end of the pusher plate 32. The inside of the aggregate box 18 is filled with sound insulation cotton. A stamping punch 5 is arranged above the support female die 2. A hydraulic cylinder 6 is installed above the stamping punch 5. A processing plate 4 is arranged between the stamping punch 5 and the support female die 2. The stamping chamber 11 is opened inside the pressure-bearing base 1. Two groups of positioning grooves 12 are opened on the inner top wall of the stamping chamber 11. The positioning rod 13 is slidably connected to the inside of the positioning groove 12. The support plate 14 is fixedly connected to the upper and lower ends of the positioning rod 13. The limiting block 15 is fixedly connected to the left side of the positioning rod 13. A support spring 16 is fixedly connected to the lower surface of the lower support plate 14. The lower end of the support spring 16 is fixedly connected to the inner bottom wall of the stamping chamber 11.
[0035] Among them, the hydraulic cylinder 6 pushes the stamping punch 5 downward. The stamping punch 5 and the support female die 2 cooperate to carry out stamping processing on the processing plate 4. During the stamping process, the waste material and the support plate 14 will be pushed downward. At this time, the cylinder 17 pushes the connecting plate 3 to the right side. At this time, the pressing plate 33 is stuck on the upper side of the limiting block 15 to fix the position of the support plate 14. Then the stamping punch 5 is lifted upward. At this time, the connecting plate 3 continues to push the pusher plate 32 to the right to push the waste material to the right side, so that it falls into the inside of the aggregate box 18. The aggregate box 18 collects the waste material to avoid the waste material from scattering on the surface of the equipment. At the same time, the rubber gasket avoids generating noise during the material discharging process, and the sound insulation cotton avoids the sound of the waste material falling from being transmitted, effectively reducing the noise during the stamping process.
[0036] Refer toFigures 3 to 6 , the cylinder 17 is fixedly installed at the left position on the upper surface of the pressure-bearing base 1. The output end of the cylinder 17 is fixedly connected to the connecting plate 3. There are two sets of push plates 32, and both sets of push plates 32 are fixedly connected to the right surface of the connecting plate 3. A connecting hole 31 is opened in the middle of the connecting plate 3. The left end of the pressing plate 33 is fixedly connected with a sliding rod 34. The sliding rod 34 is slidably connected to the connecting hole 31. A limiting spring 35 is sleeved on the surface of the sliding rod 34. The right end of the limiting spring 35 is fixedly connected to the pressing plate 33, and the left end of the limiting spring 35 is fixedly connected to the surface of the connecting plate 3. At the middle position of the left surface of the supporting female die 2 and the left position of the inner top wall of the stamping chamber 11, a limiting groove 22 is opened. The limiting block 15 is slidably connected to the limiting groove 22. Limiting holes 23 are opened at the front and rear positions on the left surface of the supporting female die 2. A discharge hole 21 is opened on the right surface of the supporting female die 2. The aggregate box 18 is fixed at the right position on the upper surface of the pressure-bearing base 1. An inlet hole is opened on the left surface of the aggregate box 18.
[0037] Specifically, in the initial state, the right end of the push plate 32 is located inside the limiting hole 23, the pressing plate 33 is located on the left side of the limiting groove 22, and at the same time, under the action of the limiting block 15, the limiting spring 35 is in a compressed state. During the stamping process, the stamping punch 5 pushes the waste material and the supporting plate 14 downward. At this time, the limiting block 15 slides downward inside the limiting groove 22. After the limiting block 15 slides to the bottommost position, the limiting spring 35 pushes the pressing plate 33 to the right, causing the pressing plate 33 to be stuck on the upper end of the limiting block 15 to limit the position of the supporting plate 14. Then, the stamping punch 5 is lifted upward. At this time, the cylinder 17 pushes the connecting plate 3 to the right. During the pushing process, the push plate 32 pushes the waste material to the right, and the waste material is sent into the interior of the aggregate box 18 through the discharge hole 21 and the inlet hole. While the push plate 32 is pushed to the right, the connecting plate 3 slides to the right on the surface of the sliding rod 34.
[0038] In addition, after the waste material is ejected, the cylinder 17 pulls the connecting plate 3 to the left. At this time, the connecting plate 3 pulls the push plate 32 and the pressing plate 33 to the left, moving the push plate 32 and the pressing plate 33 to the left side of the supporting female die 2. At this time, after the limiting block 15 loses its positioning, under the action of the supporting spring 16, the supporting plate 14 and the positioning rod 13 are pushed upward. When the supporting plate 14 and the positioning rod 13 move to the uppermost position, the cylinder 17 pushes the connecting plate 3 to the right, pushing the right end of the push plate 32 into the limiting hole 23, and making the right end of the pressing plate 33 abut against the side surface of the limiting block 15.
[0039] Working principle of the utility model: The air cylinder 17 pushes the push plate 32 and the pressing plate 33 to the right. The push plate 32 pushes the waste material to the right side, causing it to fall into the interior of the aggregate box 18, preventing the waste material from scattering on the surface of the equipment. Thus, it is not necessary to frequently stop the machine to clean the surface of the equipment, effectively improving the operating efficiency of the equipment. At the same time, the rubber gasket avoids generating noise during the process of discharging the material, and the sound insulation cotton prevents the sound of the waste material falling from being transmitted, effectively reducing the noise during the stamping process.
[0040] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and the descriptions in the specification are only the preferred examples of the utility model, and are not used to limit the utility model. Without departing from the spirit and scope of the utility model, the utility model will have various changes and improvements, and all these changes and improvements fall within the scope of the utility model claimed.
