Description

Technical Field

[0001] This utility model relates to the field of stamping devices, specifically a door and window stamping device to prevent corners from warping. Background Technology

[0002] Stamping equipment uses presses and dies to apply external force to workpieces, strips, tubes, and profiles, causing them to undergo plastic deformation or separation. In the process of manufacturing aluminum doors and windows, stamping equipment is often used to shape the materials.

[0003] According to publicly available patent 202422067195.3, an aluminum door and window stamping device for preventing corner warping is disclosed, relating to the technical field of door and window stamping devices. The device includes a bottom mold at the bottom of the operating table, with the bottom of the bottom mold snapped into the operating table. A fixing frame is located on the rear side of the operating table, with a cylinder connected to the top of the fixing frame. A pressure plate is located at the bottom of the cylinder, with a fixing mold connected to the bottom of the pressure plate. A stamping die is located at the bottom of the fixing mold. Pneumatic damping is provided around the bottom of the fixing mold, with an anti-warping plate connected to the bottom of the pneumatic damping. A limiting mechanism is located at the top of the operating table. In the process of realizing this utility model, the inventors discovered at least the following problems in the prior art. The problem remains unresolved. While traditional anti-corner warping door and window stamping devices can protect the workpiece during the stamping process, the anti-warping plate, installed at the top of the fixed mold with an anti-warping plate at its bottom, provides some protection. Under pressure, the anti-warping plate retracts due to the pneumatic damping, preventing workpiece deformation caused by excessive pressure. However, in practice, while these devices protect the workpiece, their effectiveness in protecting the stamping area is poor, resulting in corner warping during the stamping process. Therefore, a new technical solution is needed. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the existing technology, adapt to the needs of reality, and provide a door and window stamping device to prevent corners from curling up, so as to solve the technical problem that corners of door and window workpieces still curl up during the stamping process.

[0005] To achieve the purpose of this utility model, the technical solution adopted by this utility model is as follows: a door and window stamping device for preventing corner warping is designed, including a support base plate, a groove template is fixedly connected to the middle of the upper surface of the support base plate, a stamping template is set directly above the groove template, an internal groove is opened on one side of the stamping template, a stamping die head is fixedly connected to the middle of the internal groove, an abutment frame plate is sleeved on the outside of the stamping die head, four extension columns are fixedly connected to the four corners of the abutment frame plate, the other end of the four extension columns passes through the inside of the through groove and is slidably connected to the outside of the sleeve column, a return spring is set inside the sleeve column, and a corresponding vent hole is opened inside the stamping template of the stamping die head.

[0006] Preferably, four guide columns are fixedly connected to the four corners of the support base plate, support frames are fixedly connected to both sides of the support base plate, a hydraulic push rod is fixedly connected to the top of the support frame, and a mounting plate is fixedly connected to the output end of the hydraulic push rod. The mounting plate has multiple through slots.

[0007] Preferably, the mounting plate has four guide holes at its four corners, and the four guide holes are respectively fitted onto the outer surface of the four guide posts.

[0008] Preferably, the inner side of the abutment frame plate is slidably connected to the outer surface of the stamping die, and the outer side of the abutment frame plate is slidably connected to the inner wall of the built-in groove.

[0009] Preferably, the through groove extends through the interior of the stamping template, one end of the sleeve is fixedly connected to the surface of the stamping template and covers the outside of the through groove, and the other end of the sleeve is inserted into the interior of the through groove.

[0010] Preferably, one end of the return spring abuts against the inner wall of the sleeve post, and the other end of the return spring abuts against the other end of the extension post.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] When the blanking surface of the stamping die comes into contact with the workpiece, the abutment frame also comes into contact with the workpiece, thereby pressing the outer periphery of the stamping part of the workpiece with the abutment frame. During this process, the return spring will compress, thereby gradually increasing the compressive force of the abutment frame on the workpiece. The extension column will retract into the inside of the sleeve column, and the abutment frame will be housed in the inside of the built-in groove. When the stamping die is separated from the groove die, the return spring will generate a rebound force, so that the extension column will drive the abutment frame to return to its original position. This achieves the pressing of the outer periphery of the stamping part of the door and window workpiece, avoiding the phenomenon of the corners of the stamped workpiece being raised. It is beneficial to improve the protective effect of the stamping device on the stamping of door and window workpieces.

[0013] Arranging draw beads on the blanking surface of the stamping die head can uniformly control the material flow resistance and reduce local stress concentration; at the same time, opening vent holes in the die can prevent air from accumulating and causing workpiece deformation, which is conducive to further improving the protective effect of the stamping device on door and window workpieces during stamping.

[0021] The present invention will be further described below with reference to the accompanying drawings and embodiments:

[0022] Example 1: A door and window punching device to prevent corner warping, see [link / reference] Figures 1 to 5 The system includes a support base plate 1, a groove template 11 fixedly connected to the middle of the upper surface of the support base plate 1, a stamping template 12 positioned directly above the groove template 11, an internal groove 13 formed on one side of the stamping template 12, a stamping die head 14 fixedly connected to the middle of the internal groove 13, an abutment frame plate 15 fitted around the stamping die head 14, the inner side of the abutment frame plate 15 slidably connected to the outer surface of the stamping die head 14, and the outer side of the abutment frame plate 15 slidably connected to the inner wall of the internal groove 13. The internal groove 13 is designed to allow the abutment frame to be housed within it, preventing the abutment frame from hindering the stamping die head 14 from stamping the workpiece or from causing incomplete stamping of the workpiece.

[0023] Four extension posts 16 are fixedly connected to the four corners of the abutment frame 15. The other ends of the four extension posts 16 pass through the interior of the through groove 17 and are slidably connected to the exterior of the sleeve post 18. A return spring 19 is provided inside the sleeve post 18. The through groove 17 passes through the interior of the stamping template 12. One end of the sleeve post 18 is fixedly connected to the surface of the stamping template 12 and covers the exterior of the through groove 17. The other end of the sleeve post 18 is inserted into the interior of the through groove 25. One end of the return spring 19 abuts against the inner wall of the sleeve post 18, and the other end of the return spring 19 abuts against the other end of the extension post 16. When the blanking surface of the stamping die head 14 contacts the workpiece, the abutment frame... It also comes into contact with the workpiece, so that the abutment frame presses the periphery of the stamping part of the workpiece. During this process, the return spring 19 will squeeze, thereby gradually increasing the squeezing force of the abutment frame on the workpiece. The extension column 16 will retract into the inside of the sleeve column 18, and the abutment frame will be housed in the inside of the built-in groove 13. When the stamping template 12 is separated from the groove template 11, the return spring 19 will generate a rebound force, so that the extension column 16 will drive the abutment frame to reset. This achieves the pressing of the periphery of the stamping part of the door and window workpiece, avoiding the phenomenon of the corners of the stamped workpiece being raised. This is beneficial to improving the protective effect of the stamping device on the door and window workpiece during stamping.

[0024] It should be noted that the height of the abutment frame is the same as the depth of the built-in groove 13; the total elastic force of all return springs 19 is less than the thrust of the hydraulic push rod 23;

[0025] The stamping die head 14 has corresponding ventilation holes 2 inside the stamping template 12. Draw beads are arranged on the blanking surface of the stamping die head 14 to uniformly control the material flow resistance and reduce local stress concentration. At the same time, the mold has ventilation holes 2 to avoid air retention and workpiece deformation.

[0026] For details, see Figure 1 and Figure 2 Four guide pillars 21 are fixedly connected to the four corners of the support base plate 1. Support frames 22 are fixedly connected to both sides of the support base plate 1. A hydraulic push rod 23 is fixedly connected to the top of the support frame 22. A mounting plate 24 is fixedly connected to the output end of the hydraulic push rod 23. Multiple through slots 25 are provided on the mounting plate 24. When the workpiece is stamped, the output end of the hydraulic push rod 23 will extend, thereby driving the mounting plate 24 to move downward, so that the stamping template 12 coincides with the slot template 11. At this time, the stamping die head 14 will stamp the workpiece and insert it into the slot of the slot template 11.

[0027] Further, see Figure 1The mounting plate 24 has four guide holes 26 at its four corners. The four guide holes 26 are respectively fitted onto the outer surface of the four guide posts 21, allowing the mounting plate 24 to slide outside the guide posts 21 through the guide holes 26, thereby restricting the position of the mounting plate 24 when it moves up and down.

[0028] In addition, all components designed in this utility model are general standard parts or components known to those skilled in the art. Their structure and principle can be learned by those skilled in the art through technical manuals or conventional experimental methods. Those skilled in the art can fully implement them, so there is no need to elaborate. The content protected by this utility model does not involve improvements to the internal structure and method.

[0029] The embodiments disclosed herein are preferred embodiments, but are not limited thereto. Those skilled in the art can readily grasp the spirit of this utility model based on the above embodiments and make different extensions and variations. However, as long as they do not depart from the spirit of this utility model, they are all within the protection scope of this utility model.
