Description

Technical Field

[0001] The utility model relates to the technical field of stamping dies, in particular to a metal stamping die with a waste material pushing mechanism. Background Art

[0002] In the process of stamping metal sheets, some waste will be generated after stamping. In order to recycle the waste and prevent the waste from interfering with the stamping accuracy, the waste needs to be taken out of the stamping die.

[0003] In the related technology, after searching, it was found that there is a scheme of a metal sheet stamping die with waste recycling function (Announcement No. CN215279387U), in which the longitudinal rack drives the driving gear to rotate, so that the driving gear drives the transverse rack to move forward, and the transverse rack drives the waste push plate to push the waste, so that the waste enters the waste recovery frame for collection.

[0004] However, the above scheme requires first controlling the lifting plate to move up through the transmission of gears and racks, and 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 steps of cleaning the waste are relatively cumbersome. When the plates are continuously stamped, such cleaning steps affect the stamping efficiency of the plates. Utility Model Content

[0005] The utility model aims to provide a metal stamping die with a waste material pushing mechanism to solve the problems raised in the above background technology.

[0006] To achieve the above purpose, the utility model provides the following technical solutions: a metal stamping die with a waste material pushing mechanism, comprising a support table, a waste material box is installed on the lower surface of the support table, both sides of the waste material box are rotatably connected with lead screws, and the surface of the lead screw is transmission-connected with nuts, a motor is installed on the surface of the waste material box, and the motor is transmission-connected with two lead screws;

[0007] When the sheet is stamped, the waste generated falls directly into the waste box, where it can be collected for easy recycling;

[0008] A connecting rod, both ends of which are connected to a push plate, the push plate is located inside the waste box, the nut is fixedly connected to the upper push plate, when the waste in the waste box needs to be cleaned, the push plate pushes the fertilizer out, the waste can be transferred, the motor controls the movement of the push plate, the waste is automatically discharged, and manual operation is reduced;

[0009] The bracket is installed on the surface of the support platform, a punch is installed on the upper surface of the bracket, a punch seat is arranged inside the bracket, a blanking hole is arranged on the surface of the support platform and below the punching seat, and waste generated by punching falls into a waste box through the blanking hole.

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

[0011] Furthermore, the motor and the lead screw are both 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 the automatic discharge function of the waste.

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

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

[0014] Furthermore, a positioning frame is fixedly connected to the edge of the upper surface of the punching seat, and when the plate is placed, the positioning frame can make the plate placement more accurate.

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

[0016] (1) The sheet is placed on the punching seat. When the hydraulic cylinder controls the die to move down to punch the sheet, the waste generated by the punching falls directly into the waste box through the blanking hole. After the punching is completed, the sheet can be removed and the next sheet to be punched can be placed on top, which simplifies the waste cleaning process and improves the efficiency of continuous punching of sheets.

[0017] (2) The two lead screws are controlled by a motor to rotate. When the lead screws drive the nuts to translate, the nuts drive the push plates to move, pushing the waste in the waste box out, thereby realizing automatic cleaning of the waste box and making the operation of recycling waste easier.

[0024] Example:

[0025] See also Figure 1-4 The utility model provides a technical solution: a metal stamping die with a waste material pushing mechanism, comprising a support table 1, a waste material box 6 is installed on the lower surface of the support table 1, and the waste material box 6 is approximately semicircular, which is convenient for moving the waste material toward the middle of the waste material box 6 and is also conducive to the automatic discharge of the waste material;

[0026] The waste box 6 is rotatably connected to the left and right sides with lead screws 17, and the surface of the lead screws 17 is connected to the nut 18 in a transmission manner. The surface of the waste box 6 is installed with a motor 20, and the motor 20 is connected to the two lead screws 17 in a transmission manner. When the lead screw 17 rotates, the drive nut 18 translates along the lead screw 17, converting the rotational motion of the motor 20 into a linear motion, and the nut 18 can drive the push plate 7 to move;

[0027] A connecting rod 16, both ends of which are connected to a push plate 7, the push plate 7 is located inside the waste box 6, the nut 18 is fixedly connected to the upper push plate 7, and the two push plates 7 shield the two ends of the waste box 6 to prevent the waste in the waste box 6 from falling to the ground;

[0028] The bracket 10 is installed on the surface of the support platform 1. A punch is installed on the upper surface of the bracket 10. A punch seat 13 is provided inside the bracket 10. A blanking hole 15 is provided on the surface of the support platform 1 and below the punch seat 13. The punch seat 13 has a hole. When the sheet is punched, the waste moves down along the hole and finally falls into the waste box 6 through the blanking hole 15.

[0029] In this embodiment, if 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 on the lower surface of the frame 2. The square frame 2 has screw holes, and the support leg 3 has studs, so when the support leg 3 is screwed, the support leg 3 can be fine-tuned up and down, and an uneven ground will not affect the horizontal placement of the support platform 1.

[0030] In this embodiment, if Figure 1 As shown, the left and right sides of the waste box 6 are provided with fixing strips 5, and the surface of the fixing strip 5 is inserted into the screw seat 4, and 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 to achieve a fixed connection between the waste box 6 and the support platform 1. The screw seat 4 can clamp the fixing strip 5 through a nut to improve the stability of the installation of the waste box 6.

[0031] In this embodiment, if 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 can be checked whether the waste box 6 is full, and the waste can be discharged in time to prevent the waste from overflowing.

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

[0033] In this embodiment, if Figure 3 As shown, the waste box 6 is fixedly connected to the bearing seat 9, and the lower end of the screw 17 is inserted into the bearing seat 9. Four bearing seats 9 are provided to fix the screw 17 to ensure smooth rotation of the screw 17 and prevent the screw 17 from bending.

[0034] In this embodiment, if Figure 1 As shown, the punch includes a hydraulic cylinder 11 and a die 12 connected to the hydraulic cylinder 11, and the die 12 is located above the punching seat 13. The hydraulic cylinder 11 controls the die 12 to move up and down. The die 12 cooperates with the punching seat 13 to realize the punching of the plate. The waste is pushed into the waste box 6 by moving the die 12 downward.

[0035] In this embodiment, if Figure 4 As shown, a positioning frame 14 is fixedly connected to the edge of the upper surface of the punching seat 13. The positioning frame 14 is arranged in an N shape. When the plate is placed in the positioning frame 14, the plate is automatically aligned, and the punching accuracy is high.

[0036] Specifically, when in use, the plate is placed on the stamping seat 13, and the hydraulic cylinder 11 pushes the die 12 downward to stamp the plate. The waste generated by the stamping passes through the stamping seat 13 and falls downward. The drop hole 15 of the support table 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 of waste, the motor 20 rotates and controls the rotation of the screw 17 through the pulley 21 and the belt 19. The screw 17 drives the nut 18 to move, and the two nuts 18 drive the push plates 7 to move. The two push plates 7 can be used synchronously in the waste box 6 through the connecting rod 16 to push the waste in the waste box 6 out. The waste can be collected by using a barrel and the waste can be recycled in a centralized manner.
