DETAILED DESCRIPTION

[0021] In order to make the purpose and advantages of the utility model more clear, the utility model is specifically described in combination with the following embodiments. It should be understood that the following text is only used to describe one or several specific implementations of the utility model, and does not strictly limit the protection scope of the specific request of the utility model.

[0022] Please refer to Figure 1-Figure 5As shown, a steel sheet door hinge stamping die comprises a workbench 1, vertical plates 2 are vertically arranged on both sides of the upper surface of the workbench 1, a hydraulic mechanism 3 is installed across the two vertical plates 2, an upper die seat 4 is fixed downwardly at the output end of the hydraulic mechanism 3, and the upper die seat 4 is controlled by the hydraulic mechanism 3 to move up and down to realize the stamping work, a bottom plate 6 is fixed on the upper surface of the workbench 1, a lower die seat 7 is arranged on the upper surface of the bottom plate 6, the lower die seat 7 is placed directly below the upper die seat 4, a material box 8 is arranged on one side in front of the lower die seat 7, the top of the material box 8 is open, and it is placed on the right side in front of the lower die seat 7, the left inner wall of the material box 8 is flush with the material trough 71, so that the leftmost raw material plate can smoothly enter the material trough 71, and a slide bar 9 is slidably penetrated on one side surface of the material box 8, a pull button 10 is arranged at one end of the slide bar 9, and a push plate 1 is arranged at the other end of the slide bar 9 1. The push plate 11 is placed inside the material box 8. The surface of the slide bar 9 is sleeved with a spring 12. The spring 12 is placed inside the material box 8. One end of the spring 12 contacts the surface of the push plate 11. The elastic force of the spring 12 makes the push plate 11 always subjected to a leftward force, thereby pushing multiple raw material plates to the left. A raw material plate is placed inside the material box 8. The raw material plate is placed on the side of the push plate 11 away from the slide bar 9. A material groove 71 adapted to the raw material plate is provided on the upper surface of the lower die seat 7 to keep the raw material plate in a vertical state for easy rolling. An extension seat 13 is provided on the front side of one end of the material box 8 away from the slide bar 9. A slide groove 14 is provided on the upper surface of the extension seat 13. The slide groove 14 corresponds to the position of the material groove 71. The width of the slide groove 14, the raw material plate, and the material groove 71 are consistent. Therefore, when the push rod 15 is pushed, only the leftmost raw material plate can be pushed.

[0023] Please refer to Figure 1 and Figure 5 As shown, a push rod 15 is slidably installed on the inner side of the slide groove 14, and the rear end of the push rod 15 is in contact with the leftmost raw material plate. Then, when the push rod 15 is moved, the leftmost raw material plate can be pushed out of the material trough 71. When pushing, it is necessary to ensure that the raw material plate completely enters the material trough 71. A tension spring 17 is connected to the front end of the push rod 15, and the end of the tension spring 17 facing away from the push rod 15 is connected to the front surface of the inner side of the slide groove 14. The tension of the tension spring 17 is used to pull the push rod 15 back to the front after a single pushing is completed, and then the push plate 11 is used to push the remaining raw material plates to the left. A handle 16 is provided on the front end of the upper surface of the push rod 15, and the handle 16 is placed on the upper surface of the extension seat 13 to facilitate the control of the push rod 15 from the front.

[0024] Please refer to Figure 1-Figure 4 As shown, a punching die core 41 is embedded on the lower surface of the upper die base 4, and the position of the punching die core 41 corresponds to the material groove 71 to realize the curling of the raw material plate.

[0025] Among them, the lower surface of the upper die seat 4 is symmetrically provided with positioning bolts 42, and the upper surface of the lower die seat 7 is provided with positioning holes 72 adapted to the positioning bolts 42 to improve the accuracy of the docking between the upper die seat 4 and the lower die seat 7 and ensure the stamping quality.

[0026] Please refer to Figure 2 and Figure 3 As shown, a discharge guide plate 5 is provided at the rear side of the upper surface of the workbench 1 to push the stamped hinge plates backwards for easy collection.

[0027] The working principle of the utility model is as follows: when in use, the pull button 10 is pulled outward to squeeze and store force on the spring 12 through the push plate 11, and then multiple raw material plates are placed inside the material box 8 and on the left side of the push plate 11, and then the stored force of the spring 12 is used to make the multiple raw material plates have a leftward thrust, and at the same time, due to the tension of the tension spring 17, the push rod 15 is placed at the front end of the inner side of the slide groove 14 and will not enter the inner side of the material box 8. When feeding, the handle 16 can be pushed backward to drive the push rod 15 to push backward, and then the leftmost raw material plate is pushed into the material groove. 71, and then the hydraulic mechanism 3 is used to control the upper die seat 4 to move downward, so that the raw material plate can be stamped out by the cooperation of the stamping die core 41 and the material trough 71. During the downward movement of the upper die seat 4, precise positioning can be achieved through the cooperation of the positioning bolt 42 and the positioning hole 72. After a single stamping is completed, the reciprocating backward pushing handle 16 will drive multiple raw material plates to enter the inside of the material trough 71 one by one. When a new raw material plate enters the inside of the material trough 71, the stamped hinge plate can be squeezed backwards and then collected together under the guidance of the rear side discharge guide plate 5.

[0028] The above is only a preferred embodiment of the present invention. It should be noted that, for ordinary technicians in the technical field, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications should also be regarded as the protection scope of the present invention. The structures, devices and operating methods not specifically described and explained in the present invention shall be implemented according to the conventional means in the field unless otherwise specified and limited.
