Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0019] See Figures 1 to 3In an embodiment of the present utility model, a safety protection device for stamping equipment includes a base 1, a lifting frame 4, a protection pad frame 12, a hydraulic lifting pump 20, a positioning pump 21, a mold mounting assembly and an elastic control 22 assembly; the base 1 is fixedly connected to a fixed rod 2, the fixed rod 2 is slidably connected to a sliding cylinder 3, the lifting frame 4 is fixedly connected to the sliding cylinder 3, the lifting frame 4 is fixedly connected to a fixed cylinder 10, the fixed cylinder 10 is slidably connected to a sliding connecting rod 11, the protection pad frame 12 is fixedly connected to one end of the sliding connecting rod 11, a spring 13 is provided between the protection pad frame 12 and the lifting frame 4, and the bottom of the lifting frame 4 is fixedly connected to a fixed connecting rod 16, The fixed connecting rod 16 is fixedly connected to the first driving frame 23, the first driving frame 23 is fixedly connected to the sliding positioning cylinder 17, the sliding positioning cylinder 17 is slidably connected to the telescopic rod 18, the telescopic rod 18 is fixedly connected to the second driving frame 19, the hydraulic lifting pump 20 is installed on the base 1, the output shaft of the hydraulic lifting pump 20 is fixedly connected to the second driving frame 19, the positioning pump 21 is installed on the first driving frame 23, and the output shaft of the positioning pump 21 is fixedly connected to the second driving frame 19; the elastic control 22 component is installed between the protection pad frame 12 and the positioning pump 21, and is used to control the positioning pump 21; the mold mounting assembly is installed on the lifting frame 4, and is used to install and fix the stamping mold;

[0020] The utility model first installs and fixes the fixed mold 9 and the movable mold 6 through the mold installation assembly, and the fixed mold 9 is on the top and the movable mold 6 is on the bottom. Then, the second driving frame 19 can be driven to rise by the hydraulic lifting pump 20. The second driving frame 19 drives the first driving frame 23 to rise through the positioning pump 21. The first driving frame 23 drives the lifting frame 4 to rise through the fixed connecting rod 16. The lifting frame 4 drives the movable mold 6 to move toward the fixed mold 9, and then the workpiece is stamped. When the equipment is in the stamping process, if there is an object between the fixed mold 9 and the movable mold 6, the object will first contact the protective pad frame 1 when the lifting frame 4 is raised. 2. At this time, as the lifting frame 4 continues to rise, the objects will press down on the protection cushion frame 12. At this time, the protection cushion frame 12 compresses the spring 13 and drives the sliding connecting rod 11 to press down. At this time, the sliding connecting rod 11 controls the positioning pump 21 to release pressure through the elastic control component 22. At this time, the output shaft of the positioning pump 21 between the first driving frame 23 and the second driving frame 19 contracts into the positioning pump 21. At this time, the first driving frame 23 and the second driving frame 19 slide relative to each other. At this time, the movable mold 6 drops rapidly under the action of gravity, thereby protecting the objects between the movable mold 6 and the fixed mold 9.

[0021] In one embodiment of the present invention, see Figures 1 to 3The elastic control 22 component includes a connecting frame 14 fixedly connected to the other end of the sliding connecting rod 11, and a pressure button 15 is fixedly connected to the connecting frame 14. A control button 22 is installed on the top of the positioning pump 21. The control button 22 and the pressure button 15 cooperate with each other. The elastic control 22 component drives the connecting frame 14 to rise and fall through the sliding connecting rod 11, and the connecting frame 14 drives the pressure button 15 to press down, and the pressure button 15 drives the control button 22 to press down and close. At this time, the positioning pump 21 can be depressurized by controlling the control button 22.

[0022] In one embodiment of the present invention, see Figures 1 to 3 The mold mounting assembly includes a first mounting frame 5 fixedly connected to the lifting plate, a movable mold 6 is mounted on the first mounting frame 5, a fixed frame 7 is fixedly connected to the top of the fixed rod 2, a second mounting frame 8 is fixedly connected to the fixed frame 7, and a fixed mold 9 is mounted on the second mounting frame 8. The mold mounting assembly mounts the movable mold 6 on the lifting plate and the fixed mold 9 on the fixed frame 7, so that the lifting plate drives the movable mold 6 to rise and fall under the fixed mold 9, thereby stamping the raw material.
