The deformation of the product becomes larger, and the processing cost is high. Now, there is an urgent need for an internal folding and shearing device for a hardware mold to solve the above problems. Summary of the Utility Model

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0017] To make the technical means, creative features, achieved purposes, and functions of the present utility model easy to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0018] Please refer to Figures 1-3, the present utility model provides a technical solution: an internal folding and shearing device for a hardware mold, including a bending and shearing seat 1, a hardware mold frame 6, and a welding frame 10. A bending groove 2 is opened in the middle of the upper end of the bending and shearing seat 1. A plurality of spring-back grooves 3 are opened in the bending groove 2. A reset spring 4 is longitudinally installed inside each of the plurality of spring-back grooves 3. A spring-back block 5 is symmetrically installed at the upper ends of the plurality of reset springs 4. A hardware mold frame 6 is installed at the upper end of the bending and shearing seat 1. First hydraulic rods 7 are longitudinally installed on the front and rear sides of the lower end of the hardware mold frame 6. A punching block 8 is installed at the movable ends of the two first hydraulic rods 7. There are two welding frames 10, and the two welding frames 10 are symmetrically welded to the left and right ends of the bending and shearing seat 1. An inclined reinforcing plate 11 and a horizontal reinforcing plate 12 are provided on the inner sides of the two welding frames 10. A plurality of second hydraulic rods 13 are installed on the upper sides of the inclined ends of the two inclined reinforcing plates 11. Shearing grooves 14 are inclinedly opened on the left and right sides of the upper end of the bending and shearing seat 1. High-strength shearing knives 15 are symmetrically arranged in the two shearing grooves 14. This design solves the problem that the processing method of the original device is carried out separately, and it cannot complete folding and shearing in one step, and multiple processing is time-consuming and laborious.

[0019] As the first embodiment of the present utility model: A plurality of spring-back blocks 5 are all movably located in the bending groove 2. The added plurality of spring-back blocks 5 can push out the products subjected to bending and shearing from the bending groove 2.

[0020] The two inclined reinforcing plates 11 and the two horizontal reinforcing plates 12 are respectively welded to the left and right ends of the bending and shearing seat 1. By adding the two inclined reinforcing plates 11 and the two horizontal reinforcing plates 12, the firmness of the two welding frames 10 symmetrically welded to the left and right ends of the bending and shearing seat 1 can be improved, and the stability of the inclined installation of the plurality of second hydraulic rods 13 is also ensured. The movable ends of the plurality of second hydraulic rods 13 are respectively fixed to the two high-strength shearing knives 15. The added plurality of second hydraulic rods 13 can push the two high-strength shearing knives 15 to move. A bending punch 9 is installed at the lower end of the punching block 8, and the bending punch 9 is located directly above the bending groove 2. The added bending punch 9 can bend the products above the bending groove 2.

[0021] As the second embodiment of the present utility model: During actual use, place the product on the upper side of the bending groove 2, and then start the two first hydraulic rods 7. The movable ends of the two first hydraulic rods 7 can drive the stamping block 8 and the bending punch 9 to move downward. The downward-moving bending punch 9 first contacts the product and squeezes it into the bending groove 2 for slow bending (during this process, the bent product will squeeze multiple resilient blocks 5, causing the multiple resilient blocks 5 to press down multiple return springs 4, forcing the multiple return springs 4 until the resilient blocks 5 are completely moved into the multiple resilient grooves 3). At this time, the left and right sides of the product will tilt upward after bending and fit with the lower ends of the left and right sides of the bending punch 9. At this time, ensure that the bending punch 9 is still in the state of squeezing the product. Then start the multiple second hydraulic rods 13, and the multiple second hydraulic rods 13 will drive the two high-strength shearing blades 15 to move towards the tilted ends of the left and right sides of the product in the two shearing grooves 14 until the two high-strength shearing blades 15 contact the tilted ends of the left and right sides of the product and cooperate with the bending punch 9 to squeeze the tilted ends of the left and right sides of the product, so as to perform a shearing operation on the tilted ends of the left and right sides of the product. After completion, control the two first hydraulic rods 7 and the multiple second hydraulic rods 13 to return to the initial position. At this time, the multiple return springs 4 reset upward and will push the multiple resilient blocks 5 upward, causing the resilient blocks 5 to push the product that has been bent and sheared out of the bending groove 2, thereby facilitating the reuse by the staff.
