Description

Technical Field

[0001] This utility model relates to the field of stamping technology, specifically to an automatic waste discharge mechanism for stamping die production. Background Technology

[0002] Cold stamping is an important metal plastic forming process in automotive parts manufacturing. It involves applying pressure to materials at room temperature using dies mounted on a press, causing them to separate or undergo plastic deformation, thereby obtaining parts with the desired shape, size, and performance.

[0003] During the stamping production process, some stamping waste is often generated. If the stamping waste is not discharged in time, it will accumulate in the mold waste tray. The accumulation of waste will affect the mold life and part quality, and may even cause safety accidents. At present, stamping waste is still removed manually, which is not only inefficient, but also requires a dedicated person, which is costly and has operational risks.

[0004] In view of the above, this application is hereby submitted. Utility Model Content

[0005] The purpose of this utility model is to provide an automatic waste discharge mechanism for stamping die production, so as to solve the problems mentioned in the background art.

[0006] To solve the above-mentioned technical problems, this utility model provides an automatic waste discharge mechanism for stamping die production, including a die body and a support frame. A fixed frame is installed at the bottom of the die body. A discharge port is horizontally opened through the side wall of the fixed frame along the length of the die body. A horizontally arranged guide groove is vertically rotatable inside the discharge port. One end of the guide groove passes through the discharge port to the outside and the bottom of the guide groove abuts against a push rod. The bottom of the push rod rotates on the support frame.

[0007] Furthermore, the guide groove is inclined downward at one end of the top rod, and the vertical cross-section of the top rod along the width direction of the guide groove is "V" shaped. The top rod includes a horizontally fixed shaft that rotates at the top of the support frame. A self-locking telescopic rod is fixed on the outer arc wall of the fixed shaft, and a horizontal fixed rod is fixed at the end of the self-locking telescopic rod away from the fixed shaft. Both ends of the fixed shaft in the top rod along its axial direction are equipped with bearings of the same structure, and the bearings are installed at the top of the support frame.

[0008] Furthermore, the fixed rod at the top of the top rod abuts against the bottom of the guide groove, and the fixed rod at the bottom of the top rod is connected to a cylinder. The cylinder is mounted on the support frame, and the output end of the cylinder is vertically rotatably connected to a rotating block. The end of the rotating block away from the cylinder is vertically rotatably connected to a connecting rod, and the end of the connecting rod away from the rotating block is fixed to the bottom end of the top rod. A limit rod is fixed in the middle of the bottom end of the support frame, and the fixed rod at the bottom of the top rod abuts against the limit rod.

[0009] Compared with the prior art, the beneficial effects of this utility model are:

[0010] 1. The swing of the ejector rod is controlled by a cylinder, which in turn controls the swing of the guide groove. With the tilting setting of the guide groove, the waste material falls freely into the discharge port after stamping and is discharged through the guide groove. This reduces manual intervention, improves production efficiency, avoids workers directly contacting waste material, reduces labor intensity, improves the working environment, enhances production safety, and prevents waste material from adversely affecting the mold and stamped parts, thereby ensuring the stable and reliable quality of the stamped parts.

[0011] 2. This design has a simple structure, is easy to maintain and operate. When a fault occurs, maintenance personnel can quickly locate the problem and repair it, reducing equipment downtime and maintenance costs. It is also easy to adjust and change according to actual production needs and is easy to learn. Attached Figure Description

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see the appendix Figure 1 To be continued Figure 4 The present invention provides an automatic waste discharge mechanism for stamping die production: including a die body 10 and a support frame 15. A fixed frame 101 is installed at the bottom of the die body 10. A discharge port 11 is horizontally opened through the side wall of the fixed frame 101 along the length direction of the die body 10. A horizontally arranged guide groove 12 is vertically rotatable in the discharge port 11. One end of the guide groove 12 passes through the discharge port 11 to the outside and the bottom of the guide groove 12 abuts against a push rod 13. The bottom of the push rod 13 rotates on the support frame 15.

[0022] The guide groove 12 is inclined downward at one end corresponding to the top rod 13. The vertical cross section of the top rod 13 along the width direction of the guide groove 12 is "V" shaped. The top end of the top rod 13 abuts against the bottom of the guide groove 12. The bottom of the top rod 13 is connected to a cylinder 17, which is mounted on the support frame 15.

[0023] The top rod 13 includes a horizontally fixed shaft that rotates at the top of the support frame 15. A self-locking telescopic rod 131 is fixed on the outer arc wall of the fixed shaft. A horizontal fixed rod is fixed at the end of the self-locking telescopic rod 131 away from the fixed shaft. The fixed rod abuts against the bottom of the guide groove 12.

[0024] The fixed shaft in the top rod 13 is equipped with bearings 14 of the same structure at both ends along its axial direction. The bearings 14 are installed on the top of the support frame 15. The output end of the cylinder 17 is vertically rotatably connected to a rotating block 18. The end of the rotating block 18 away from the cylinder 17 is vertically rotatably connected to a connecting rod 19. The end of the connecting rod 19 away from the rotating block 18 is fixed to the bottom end of the top rod 13.

[0025] The support frame 15 has a limiting rod 16 fixed at the bottom center, and the fixed rod at the bottom of the top rod 13 abuts against the limiting rod 16.

[0026] It should be noted that: it is understood that the support frame 15 is located below the side of the mold body 10, the cylinder 17 is in the initial retracted state, and the ejector rod 13 is driven to swing through the rotating block 18 and the connecting rod 19. The waste generated during the stamping process falls freely into the guide groove 12 in the discharge port 11 under the action of gravity. Since the guide groove 12 is inclined, the waste will slide down along the inclined direction of the guide groove 12.

[0027] When it is necessary to discharge the waste in the guide groove 12, the cylinder 17 begins to extend and retract alternately, which in turn drives the end of the guide groove 12 to swing continuously, so that the waste can slide out along the guide groove 12 more quickly and smoothly, and finally be discharged to the designated waste collection area.

[0028] The number and width of the guide groove 12 and the discharge port 11 are determined by the structure of the specific mold or the specific production requirements. When switching to different mold bodies 10 for production, only the corresponding fixing frame 101 needs to be replaced.

[0029] The length of the self-locking telescopic rod 131 can be manually adjusted to control the swing amplitude of the top rod 13, thereby changing the swing amplitude of the guide groove 12.

[0030] Working principle:

[0031] The support frame 15 is located below the side of the mold body 10. The cylinder 17 initially retracts and drives the ejector rod 13 to swing through the rotating block 18 and the connecting rod 19. During stamping, the scrap falls into the guide groove 12 in the discharge port 11 under the action of gravity. Because the guide groove 12 is inclined, the scrap slides down along it.

[0032] When waste needs to be discharged, the cylinder 17 extends and retracts alternately. Through the rotating block 18 and the connecting rod 19, the push rod 13 drives the end of the guide groove 12 to swing continuously, allowing the waste to slide out more smoothly to the collection area. The number and width of the guide groove 12 and the discharge port 11 are determined according to the mold structure or production requirements. When changing the mold body 10, the fixing frame 101 can be replaced.

[0033] The length of the self-locking telescopic rod 131 can be manually adjusted to control the swing amplitude of the top rod 13, thereby changing the swing amplitude of the guide groove 12.
