Description

Technical Field

[0001] This utility model relates to the field of stamping die technology, and in particular to a sheet metal stamping die. Background Technology

[0002] Sheet metal processing is a comprehensive cold working process for thin metal sheets (usually less than 6mm), including shearing, punching / cutting / combined cutting, bending, welding, riveting, splicing, and forming (such as car bodies). Its significant characteristic is that the thickness of the same part is consistent. Products processed by sheet metal processing are called sheet metal parts. The sheet metal parts referred to in different industries are generally different, and are mostly used as a term for assembly. In sheet metal production, stamping is required.

[0003] In the process of sheet metal stamping, stamping dies are required. However, existing sheet metal stamping dies often require different dies to be changed when stamping sheet metal of different sizes, which has certain limitations. At the same time, after stamping, it is difficult to remove the thin metal sheet from the die slot, which indirectly increases the downtime of the production line. Utility Model Content

[0006] By adopting the above technical solution, the movement of the pushing component, and under the limiting action of the rotating cylinder, causes the roller and the fixed seat to move upward, which will compress the spring and produce a tightening phenomenon, thereby enabling the ejector pin to push out the sheet metal finished product in the mold body.

[0007] In a preferred embodiment, the top of the support plate is provided with a replacement component, which includes three limiting grooves opened inside the turntable. Each limiting groove is slidably connected to a limiting post. The top of the support plate is fixedly connected to three limiting guide rails.

[0017] In a preferred embodiment, support rods are fixedly connected to the four corners of the top of the support plate, a fixing plate is fixedly connected between the tops of the four support rods, and an upper template is slidably connected between the four fixing rods.

[0018] By adopting the above technical solution, and through the use of support rods and fixing plates, stability can be provided for the stamping cylinder and stamping head.

[0019] In a preferred embodiment, a punching head is fixedly installed at the bottom end of the upper template, and a punching cylinder is fixedly installed at the top end of the fixed plate, with the piston rod of the punching cylinder fixedly connected to the upper template.

[0020] By adopting the above technical solution, the upper template and the stamping head can be pushed downward by the extension and retraction of the piston rod of the stamping cylinder.

[0021] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0022] 1. In this utility model, after the sheet metal stamping is completed, the roller and the fixed seat can be moved upward by the movement of the pushing part and under the limiting action of the rotating cylinder. This will compress the spring and produce a tightening phenomenon, thereby using the ejector pin to push out the sheet metal finished product in the mold body. This can improve the convenience of sheet metal material removal, reduce some downtime, and improve work efficiency.

[0023] 2. In this utility model, when the turntable rotates, the limiting groove drives the limiting column to move, thereby pulling the clamping parts to slide on the limiting guide rail. The use of the limiting guide rail can play an important limiting role for the clamping parts, ensuring the normal operation of the replacement components. Thus, the three clamping parts can be used to clamp and fix the mold body, thereby facilitating the replacement of the mold body and improving work efficiency. Attached Figure Description

[0029] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0030] Reference Figure 1-4 A sheet metal stamping die includes a support plate 1, a rotating cylinder 15 rotatably mounted inside the support plate 1, a turntable 20 fixedly connected to the top of the rotating cylinder 15, an ejector pin 16 slidably connected inside the rotating cylinder 15, a fixing groove opened inside the support plate 1, the bottom end of the ejector pin 16 extending into the fixing groove and fixedly connected to a fixing seat 10, a spring 11 sleeved on the outside of the ejector pin 16 between the fixing seat 10 and the inner wall of the fixing groove, a roller 9 fixedly mounted at the bottom of the fixing seat 10, and a pusher 8 slidably connected to the inner wall of the fixing groove. After the sheet metal stamping is completed, the roller 9 and the fixing seat 10 move upward by the movement of the pusher 8 and under the limiting action of the rotating cylinder 15, thereby compressing the spring 11 and causing a compression phenomenon, so that the sheet metal finished product in the die body 2 can be pushed out by the ejector pin 16, thereby improving the convenience of sheet metal removal, reducing some downtime, and improving work efficiency.

[0031] Specifically, the top of the support plate 1 is equipped with a replacement component, which includes three limiting grooves 6 inside the turntable 20. Each limiting groove 6 has a slidably connected limiting post 7. The top of the support plate 1 is fixedly connected to three limiting guide rails 3. When the turntable 20 rotates, the limiting grooves 6 drive the limiting posts 7 to move, thereby pulling the clamping parts 4 to slide on the limiting guide rails 3. The limiting guide rails 3 play a crucial limiting role in the clamping parts 4, ensuring the normal operation of the replacement component. The three clamping parts 4 can then be used to clamp and fix the mold body 2, facilitating the replacement of the mold body 2 and improving work efficiency. Each limiting guide rail 3 has a slidably connected clamping part 4 on its top. The corresponding limiting post 7 is fixedly connected. The support plate 1 has an installation groove inside and above the fixing groove. The installation groove is equipped with a transmission assembly. The transmission assembly includes a cylinder 12 fixedly installed on the inner wall of the installation groove. The bottom end of the rotating cylinder 15 extends into the installation groove. By extending and retracting the piston rod of the cylinder 12, the rack 13 can be moved, thereby driving the gear 14 to rotate, which in turn drives the rotating cylinder 15 and the turntable 20 to rotate, thus realizing the transmission of power. The gear 14 is fixedly connected to the outer side of the rotating cylinder 15. The transmission assembly also includes a rack 13 fixedly connected to the piston rod of the cylinder 12. The rack 13 meshes with the gear 14. The setting of the cylinder 12 can provide a power source for the movement of the rack 13.

[0032] Specifically, roller 9 abuts against pusher 8. A push rod is fixedly connected to the side of pusher 8 away from roller 9. The push rod allows the operator to push pusher 8. The end of push rod away from pusher 8 extends to the outside of support plate 1. Mold body 2 is clamped between three clamping members 4. The mold body 2 and turntable 20 are both provided with insertion holes for use with ejector pins 16 to push out sheet metal from inside mold body 2. Support rods are fixedly connected to the four corners of the top of support plate 1. A fixed plate 18 is fixedly connected between the parts. The use of the support rod and the fixed plate 18 can provide stability for the stamping cylinder 19 and the stamping head 17. The upper template 5 is slidably connected between the four fixed rods. The stamping head 17 is fixedly installed at the bottom of the upper template 5. By extending and retracting the piston rod of the stamping cylinder 19, the upper template 5 and the stamping head 17 can be pushed downward, thereby achieving the purpose of stamping sheet metal. The stamping cylinder 19 is fixedly installed at the top of the fixed plate 18. The piston rod of the stamping cylinder 19 is fixedly connected to the upper template 5.

[0033] Working principle: First, the operator can place the sheet metal material into the mold body 2. Then, the stamping cylinder 19 is started by controlling the external controller. The extension and retraction of the piston rod of the stamping cylinder 19 can push the upper template 5 and the stamping head 17 downward, thereby achieving the stamping purpose of the sheet metal. After the sheet metal stamping is completed, the push rod can be manually pushed to drive the pusher 8 to move. Under the limiting action of the rotating cylinder 15, the roller 9 and the fixed seat 10 move upward, which will compress the spring 11 and produce a tightening phenomenon. Then, the ejector pin 16 can push out the finished sheet metal in the mold body 2, thereby improving the sheet metal material handling efficiency. The convenience of this system allows for easy replacement of the mold body 2. When the mold body 2 needs to be replaced, the cylinder 12 can be activated, which can move the rack 13, thereby driving the gear 14 to rotate. This, in turn, drives the rotating cylinder 15 and the turntable 20 to rotate. Subsequently, the limiting groove 6 drives the limiting post 7 to move, which in turn pulls the clamping part 4 to slide on the limiting guide rail 3. The use of the limiting guide rail 3 plays an important limiting role for the clamping part 4, ensuring the normal operation of the replacement components. Thus, the three clamping parts 4 can be used to clamp and fix the mold body 2, thereby facilitating the replacement of the mold body 2 and improving work efficiency.
