Description

Technical Field

[0001] This utility model relates to the field of stamping die technology, specifically a metal stamping die with a scrap ejector mechanism. Background Technology

[0002] During the stamping process of metal sheets, some waste material is generated after stamping. In order to recycle the waste material and prevent it from interfering with the stamping accuracy, the waste material needs to be removed from the stamping die.

[0003] In related technologies, a search revealed a scheme for a metal sheet stamping die with waste recycling function (announcement number CN215279387U). The longitudinal rack drives the drive gear to rotate, which in turn drives the transverse rack to move forward. The transverse rack drives the waste pusher to push the waste into the waste recycling box for collection.

[0004] However, the above solution requires first controlling the lifting plate to move up through the transmission of gears and racks, then cleaning the waste on the lifting plate through the waste pusher plate, and then resetting the lifting plate and the waste pusher plate. The waste cleaning process is quite cumbersome, and such a cleaning process affects the stamping efficiency of the sheet metal when it is continuously stamped. Utility Model Content

[0005] The purpose of this invention is to provide a metal stamping die with a scrap pushing mechanism to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a metal stamping die with a scrap pushing mechanism, comprising a support platform, a scrap box installed on the lower surface of the support platform, lead screws rotatably connected to both sides of the scrap box, and nuts drivingly connected to the surface of the lead screws; a motor is installed on the surface of the scrap box, and the motor is drivingly connected to the two lead screws.

[0007] During sheet metal stamping, the waste generated falls directly into the waste box, which can collect the waste and facilitate recycling.

[0008] A connecting rod is provided, with push plates connected to both ends. The push plates are located inside the waste box. The nut is fixedly connected to the upper push plate. When it is necessary to clean the waste in the waste box, the push plate pushes the waste out, which can transfer the waste. The motor controls the movement of the push plate to realize the automatic discharge of waste and reduce manual operation.

[0009] The bracket is mounted on the surface of the support platform. A stamper is mounted on the upper surface of the bracket. A stamping seat is provided inside the bracket. A material discharge hole is provided on the surface of the support platform and below the stamping seat. Waste generated by stamping falls into a waste box through the material discharge hole.

[0010] Furthermore, a square frame is installed on the lower surface of the support platform, and a support leg is screwed onto the lower surface of the square frame. The support platform can be leveled by turning the support leg. When the ground is uneven, the support platform can also be placed horizontally on the ground.

[0011] Furthermore, both the motor and the lead screw are equipped with pulleys, and belts are installed on the surfaces of the three pulleys. The motor controls the rotation of the two lead screws through the belts, and the rotation of the lead screws controls the translation of the push plate, thereby realizing the automatic movement of the push plate and thus realizing the automatic discharge of waste materials.

[0012] Furthermore, the waste box is fixedly connected to a bearing seat, and the lower end of the lead screw is inserted into the bearing seat. The bearing seat can support the lead screw, ensuring that the lead screw will not bend, while reducing the resistance to the rotation of the lead screw, making the push plate move more smoothly.

[0013] Furthermore, the stamping device includes a hydraulic cylinder and a die connected to the hydraulic cylinder, with the die located above the stamping seat. The hydraulic cylinder controls the die to move downward, and the sheet metal is placed on the stamping seat to achieve automatic stamping of the sheet metal.

[0014] Furthermore, a positioning frame is fixedly connected to the edge of the upper surface of the stamping base. When placing the sheet metal, the positioning frame can make the sheet metal more accurately placed.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] (1) The plate is placed by the stamping seat and the hydraulic cylinder controls the die to move down to stamp the plate. The waste generated by stamping falls directly into the waste box through the discharge hole. After stamping is completed, the plate can be removed and the next plate to be stamped can be turned over, which simplifies the waste cleaning process and makes the continuous stamping of the plate more efficient.

[0017] (2) By controlling the rotation of two lead screws by the motor, when the lead screw drives the nut to move, the nut drives the push plate to move and push the waste in the waste box out, so as to realize the automatic cleaning of the waste box and make the operation of recycling waste easier.

Detailed Implementation

[0023] 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.

[0024] Example:

[0025] Please see Figure 1-4 This utility model provides a technical solution: a metal stamping die with a waste pushing mechanism, including a support platform 1, and a waste box 6 is installed on the lower surface of the support platform 1. The waste box 6 is approximately semi-circular, which facilitates the movement of waste towards the center of the waste box 6 and also facilitates the automatic discharge of waste.

[0026] The waste box 6 is rotatably connected to both sides by lead screws 17, and nuts 18 are driven to the surface of the lead screws 17. A motor 20 is installed on the surface of the waste box 6, and the motor 20 is driven to the two lead screws 17. When the lead screws 17 rotate, they drive the nuts 18 to translate along the lead screws 17, converting the rotational motion of the motor 20 into linear motion. The nuts 18 can drive the push plate 7 to move.

[0027] The connecting rod 16 has push plates 7 connected to both ends. The push plates 7 are located inside the waste box 6. The nut 18 is fixedly connected to the upper push plate 7. The two push plates 7 cover both ends of the waste box 6 to prevent the waste in the waste box 6 from falling to the ground.

[0028] A bracket 10 is mounted on the surface of a support platform 1. A stamper is mounted on the upper surface of the bracket 10. A stamping seat 13 is provided inside the bracket 10. A material discharge hole 15 is provided on the surface of the support platform 1 and below the stamping seat 13. The stamping seat 13 has holes. When stamping the sheet metal, the scrap moves down along the holes and finally falls into the scrap box 6 through the material discharge hole 15.

[0029] In this embodiment, as Figure 1As shown, a square frame 2 is installed on the lower surface of the support platform 1, and a support leg 3 is screwed onto the lower surface of the square frame 2. The square frame 2 has screw holes, and the support leg 3 has studs. Therefore, when the support leg 3 is turned, the support leg 3 can be adjusted up and down slightly, and uneven ground will not affect the horizontal placement of the support platform 1.

[0030] In this embodiment, as Figure 1 As shown, the waste box 6 is provided with fixing strips 5 on both the left and right sides. The surface of the fixing strip 5 is inserted into the screw seat 4. The screw seat 4 is screwed to the support platform 1. The screw seat 4 fixes the fixing strip 5 to the lower surface of the support platform 1, realizing the fixed connection between the waste box 6 and the support platform 1. The screw seat 4 can clamp the fixing strip 5 with the nut, which improves the stability of the waste box 6 installation.

[0031] In this embodiment, as Figure 1 As shown, an observation window 8 is installed in the middle of the surface of the push plate 7. Through the observation window 8, it is possible to check whether the waste box 6 is full and to discharge the waste in time to prevent the waste from overflowing.

[0032] In this embodiment, as Figure 3 As shown, both the motor 20 and the lead screw 17 are equipped with pulleys 21. The surfaces of the three pulleys 21 are covered with belts 19. When the pulley 21 connected to the motor 20 rotates, the pulley 21 drives the other two pulleys 21 to rotate through the belts 19, ensuring that the motor 20 can smoothly drive the lead screw 17 to rotate.

[0033] In this embodiment, as Figure 3 As shown, the waste box 6 is fixedly connected to a bearing seat 9, and the lower end of the lead screw 17 is inserted into the bearing seat 9. There are four bearing seats 9, which can fix the lead screw 17, ensure that the lead screw 17 rotates smoothly, and prevent the lead screw 17 from bending.

[0034] In this embodiment, as Figure 1 As shown, the stamping device includes a hydraulic cylinder 11 and a die 12 connected to the hydraulic cylinder 11. The die 12 is located above the stamping seat 13. The hydraulic cylinder 11 controls the die 12 to move up and down. The die 12 and the stamping seat 13 cooperate to realize the stamping of the sheet metal. By moving the die 12 down, the waste material is pushed into the waste box 6.

[0035] In this embodiment, as Figure 4 As shown, a positioning frame 14 is fixedly connected to the edge of the upper surface of the stamping base 13. The positioning frame 14 is n-shaped. When the plate is placed in the positioning frame 14, the plate is automatically aligned, resulting in high stamping accuracy.

[0036] Specifically, during use, the sheet metal is placed on the stamping seat 13, and the hydraulic cylinder 11 pushes the die 12 down to stamp the sheet metal. The waste generated during stamping falls down through the stamping seat 13. The material drop hole 15 of the support platform 1 allows the waste to fall into the waste box 6. The observation window 8 is used to check whether the waste box 6 needs to be cleaned. When the waste box 6 needs to be cleaned, the motor 20 rotates and controls the lead screw 17 to rotate through the pulley 21 and belt 19. The lead screw 17 drives the nut 18 to move. The two nuts 18 drive the push plate 7 to move. The two push plates 7 can be used simultaneously in the waste box 6 through the connecting rod 16 to push the waste out of the waste box 6. The waste can then be collected in a bucket for centralized recycling.

[0037] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
