Description

Technical Field

[0001] This utility model relates to the field of stamping die technology, specifically to a waste material guiding structure for stamping dies. Background Technology

[0002] Stamping dies are special process equipment used in cold stamping to process materials (metal or non-metal) into parts (or semi-finished products). They are called cold stamping dies (commonly known as cold stamping dies). Stamping is a pressure processing method that uses dies mounted on a press to apply pressure to materials at room temperature, causing them to separate or plastically deform, thereby obtaining the desired parts.

[0003] Chinese Patent Publication No. CN222695876U discloses a waste material guiding structure for a stamping die, including a mounting frame. The mounting frame has a frame structure, and fixing plates are fixed on the inner walls of both sides of the mounting frame. A first guide roller is rotatably connected between the two fixing plates. There are two sets of the first guide rollers. A driving mechanism is installed on the side of the mounting frame. Compared with the prior art, this utility model uses a lifting mechanism to drive the movable frame and the second guide roller downward, so that the second guide roller is close to the first guide roller. The first and second guide rollers clamp the strip material. During the stamping process, the driving mechanism drives the first guide roller, so that the first guide roller and the second guide roller cooperate to drive the strip material. After the strip material is stamped, the remaining waste material is guided out, which facilitates the next stamping step. This improves both stamping accuracy and safety.

[0004] The waste material guiding structure in the aforementioned patent and similar devices commonly found on the market have the common problem that they cannot effectively clean the stamping head during the waste stamping process. The stamping head often carries the surface waste and continues to stamp. The adhesion of waste not only damages the product surface but may also damage the mold components. Utility Model Content

[0005] To address the aforementioned issues, a scrap guiding structure for a stamping die is provided. When the stamping head enters the load-bearing plate, the protective plate rotates under the action of the bulletproof mechanism. The protective plate prevents scrap from rebounding, and the bulletproof mechanism keeps the operating plate vertical while rotating. By changing the angle of the operating plate, the jet direction of the jet nozzle can be adjusted, effectively cleaning the scrap on the surface of the stamping head and preventing incomplete scrap cleaning that could damage the die surface.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a waste material guiding structure for a stamping die, comprising a worktable and a load-bearing plate, the load-bearing plate being disposed on the top of the worktable, a lifting mechanism being disposed on the top of the load-bearing plate, a stamping head being disposed below the lifting mechanism, bulletproof mechanisms being symmetrically disposed below the load-bearing plate, an operating plate being rotatably mounted on the side of the bulletproof mechanism, a dust removal mechanism being disposed below the operating plate, and a material discharge plate being disposed inside the worktable and below the dust removal mechanism.

[0007] Furthermore, the lifting mechanism includes a movable plate, which is positioned above the load-bearing plate. Piston rods are symmetrically installed at the bottom of the movable plate, and one end of the piston rod is provided with a cylinder that is connected to the worktable.

[0008] Furthermore, the bulletproof mechanism includes a protective plate, which is rotatably mounted on the bottom of the load-bearing plate. A positioning plate is provided on the side of the protective plate and located at the bottom of the load-bearing plate. The protective plate and the positioning plate are connected by a return spring.

[0009] Furthermore, the operation panel has symmetrically arranged positioning slots inside, and a counterweight is engaged inside the positioning slot.

[0010] Furthermore, the dust removal mechanism includes a jet nozzle, which is rotatably mounted on the bottom of the control panel, and the jet nozzle is connected to the cylinder body via an air supply pipe.

[0011] Furthermore, a feeding plate is mounted inside the workbench via a hinge, and a base plate is provided below the feeding plate. The feeding plate and the base plate are connected by a compression spring.

[0012] Furthermore, a base is provided below the workbench, and the workbench and the base are connected by a vertical plate. A waste box is provided on the top of the base and at the bottom of the feed plate.

[0013] Compared with the prior art, the beneficial effects of this utility model are: the waste material guiding structure of this stamping die is reasonable and has the following advantages:

[0014] (1) The lifting mechanism drives the stamping head to rise and fall, which facilitates the extrusion of waste. When the stamping head enters the load-bearing plate, the protective plate rotates under the action of the bulletproof mechanism. The protective plate prevents the waste from rebounding. The rebounding of waste will not only damage the product surface, but may also damage the mold components. The bulletproof mechanism keeps the operating plate vertical while rotating. By changing the angle of the operating plate, the jet direction of the jet head can be adjusted, which can effectively clean the waste on the surface of the stamping head and avoid incomplete waste cleaning, which may cause damage to the mold surface.

[0015] (2) The device is installed with a hinge and the material feed plate is connected to the base plate through a compression spring. When the waste material at the top of the material feed plate reaches a certain weight, the rotation angle of the material feed plate changes, which can change the discharge angle of the waste material, making the waste material discharge more convenient. The waste material box on the base can collect the waste material generated during the die stamping process, avoid the accumulation of waste material, and avoid the occurrence of waste material rebound, etc. It has high practicality.

[0022] 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.

[0023] Please see Figure 1-5 The present invention provides a technical solution.

[0024] A waste material guiding structure for a stamping die includes a workbench 1 and a load-bearing plate 2. The load-bearing plate 2 is located on the top of the workbench 1. A lifting mechanism 3 is located on the top of the load-bearing plate 2. A stamping head 4 is located below the lifting mechanism 3. Bulletproof mechanisms 5 are symmetrically arranged below the load-bearing plate 2. An operating plate 6 is rotatably mounted on the side of the bulletproof mechanism 5. A dust removal mechanism 8 is located below the operating plate 6. A discharge plate 9 is located inside the workbench 1 and below the dust removal mechanism 8.

[0025] In this embodiment, the load-bearing plate 2 is threaded onto the top of the workbench 1 for easy operation of the device. Then, the lifting mechanism 3 is connected to the external power component on the top of the punch head 4. When the power component is working, the lifting mechanism 3 and the punch head 4 move simultaneously. Under the action of the punch head 4, the waste material is squeezed out, and the dust removal mechanism 8 is inflated through the lifting mechanism 3. When the punch head 4 enters the interior of the load-bearing plate 2, the waste material can be effectively prevented from rebounding under the action of the bulletproof mechanism 5. Preventing the waste material from rebounding not only damages the product surface but may also damage the mold components. While the bulletproof mechanism 5 is rotating, the operating plate 6 remains vertical. The dust removal mechanism 8 on the operating plate 6 can effectively clean the waste material on the surface of the punch head 4. The cleaned waste material accumulates above the unloading plate 9, making it convenient for the user to centrally process the waste material.

[0026] In this embodiment, the lifting mechanism 3 includes a movable plate 31, which is positioned above the load-bearing plate 2. Piston rods 32 are symmetrically mounted on the bottom of the movable plate 31. One end of the piston rod 32 is connected to a cylinder 33 that is connected to the workbench 1. A piston is provided at one end of the piston rod 32. An inlet check valve and an exhaust valve are provided on the cylinder 33. The inlet check valve is installed below the side of the air storage cylinder 33 and is on the same plane as the air supply pipe 82. The exhaust valve is installed on the air supply pipe 82. When the movable plate 31 rises, the inlet check valve opens and the exhaust valve closes. The piston rod 32 moves inside the cylinder 33, which can charge the cylinder 33 with air. When the piston rod 32 is pressed down to a certain position, the inlet check valve closes and the exhaust valve opens, which can discharge the gas inside the cylinder 33, facilitating the use of the jet nozzle 81.

[0027] In this embodiment, the bulletproof mechanism 5 includes a protective plate 51, which is rotatably mounted on the bottom of the load-bearing plate 2. A positioning plate 52 is provided on the side of the protective plate 51 and located at the bottom of the load-bearing plate 2. The protective plate 51 and the positioning plate 52 are connected by a return spring. When the punch head 4 penetrates into the load-bearing plate 2, the protective plate 51 contacts the upper surface of the punch head 4 under the action of the positioning plate 52 and the return spring. When the punch head 4 finishes cleaning, the protective plate 51 rotates during the upward movement of the punch head 4, which can reduce the waste discharge port and avoid the waste rebound phenomenon, thereby improving the working quality of the equipment.

[0028] In this embodiment, the operation plate 6 has symmetrically arranged positioning slots inside, and a counterweight 7 is engaged and installed inside the positioning slots. The counterweight 7 can be installed through the positioning slots inside the operation plate 6. The weight of the counterweight 7 can keep the operation plate 6 in a vertical state, which can limit the working direction of the jet head 81 and improve the dust removal efficiency of the device.

[0029] In this embodiment, the dust removal mechanism 8 includes a jet nozzle 81, which is rotatably mounted on the bottom of the operating plate 6. The jet nozzle 81 is connected to the cylinder 33 via an air supply pipe 82. The jet nozzle 81 is installed on the operating plate 6 and the jet direction of the jet nozzle 81 is adjusted according to the mold. When the stamping head 4 stamps the waste material, the waste material inside the cylinder 33 is transported through the air supply pipe 82 and sprayed out under the action of the jet nozzle 81, thus avoiding the problem of incomplete removal of waste material from the surface of the stamping head 4 and improving the stamping quality of the product.

[0030] In this embodiment, a feeding plate 9 is mounted inside the workbench 1 via a hinge. A base plate 10 is located below the feeding plate 9, and the feeding plate 9 and the base plate 10 are connected by a compression spring. The feeding plate 9 is mounted under the action of the hinge, and at the same time, the feeding plate 9 is connected to the base plate 10 via the compression spring. When the waste material at the top of the feeding plate 9 reaches a certain weight, the rotation angle of the feeding plate 9 changes, which can change the discharge angle of the waste material, making the discharge of waste material more convenient.

[0031] In this embodiment, a base 11 is provided below the workbench 1. The workbench 1 and the base 11 are connected by a vertical plate. A scrap box 12 is provided on the top of the base 11 and at the bottom of the feed plate 9. The workbench 1 and the base 11 are installed by the vertical plate, and the scrap box 12 is placed under the action of the base 11. The scrap box 12 can collect the scrap generated during the die stamping process, avoid the accumulation of scrap, and prevent the scrap from rebounding. It also facilitates the processing of scrap.

[0032] The above embodiments only illustrate one or more implementations of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of this utility model. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the appended claims.
