Technical Field
[0001] The utility model relates to the field of punching equipment for stamping parts, in particular to a punching equipment for hardware stamping parts. Background Art
[0002] Metal stamping equipment is the so-called press. Scientific name: stamping machine, oil press, hydraulic press. It is a special equipment for pressing hardware. Stamping equipment is based on the plastic deformation of metal. It uses molds and stamping equipment to apply pressure to the sheet material to make the sheet material plastically deform or separate, thereby obtaining parts (stamping parts) with certain shapes, sizes and performances. Existing metal stamping and drilling equipment is generally divided into large-scale automated machines and small portable equipment.
[0003] Large-scale automated equipment has greatly reduced labor costs, and the operation is simpler, more efficient, and safer. The specifications of the stamped materials are wide, and more hardware parts can be produced. During operation, the stamped materials need to be fed into the hopper, then transferred to the stamping area, and finally transferred to the collection box. Small portable equipment requires manual assistance. It is necessary to manually adjust the position of the stamped parts, place the stamped parts under the punch, start the stamping equipment for stamping, and manually take out the stamped parts for storage when the stamping is completed. The specifications of small portable equipment are limited, and stamped materials of different sizes require stamping equipment of different sizes.
[0004] Large-scale equipment Large-scale automated equipment is generally more expensive and has size restrictions on the installation site; general small factories or hardware stores cannot support a large-scale automated stamping equipment, so many small factories and hardware stores choose small portable equipment; however, small portable equipment cannot meet the stamping conditions of multiple sizes of pressed materials, so it is also necessary to purchase multiple devices, which will increase its cost.

[0040] The working principle of the utility model is as follows: when the distance between the two groups of conveyor belts 11 needs to be adjusted, the handle 24 is rotated clockwise, and the handle 24 drives the screw rod 23 to rotate. According to the screw rod principle, when the screw rod 23 rotates, the two groups of support frames 25 are brought closer to each other, so that the two groups of second brackets 8 are brought closer to each other; when the handle 24 is rotated counterclockwise, the screw rod 23 is driven to rotate in the opposite direction, so that the two groups of support frames 25 are moved away from each other, so that the two groups of second brackets 8 are moved away from each other; when the second bracket 8 moves, the rotating wheel 10 is driven to slide on the outer wall of the first square rotating shaft 6 and the second square rotating shaft 9. After the adjustment is completed, the pressing material is placed above the two groups of conveyor belts 11, and then the motor 27 is started, and the electric The motor 27 drives the second square rotating shaft 9 to rotate, and the rotation of the second square rotating shaft 9 drives the rotating wheel 10 to rotate. At the same time, the conveyor belt 11 set on the outer wall of the rotating wheel 10 starts to work, and the conveyor belt 11 conveys the pressing material placed above it. When it moves to the top of the lower template 18, the motor 27 stops working, and then starts the hydraulic rod 2. The hydraulic rod 2 drives the upper mold frame 5 to move downward, so that the punch 22 punches the pressing material. After the punching is completed, the waste material falls through the punching hole 183 of the lower template 18 to the lower template fixing frame 181 for storage. The motor 27 continues to move. When the pressing material is transmitted to the end of the conveyor belt 11, it falls into the collection frame 17.
[0041] The rotation of the rotating wheel 10 drives the circular rotating rod 91 at the end of the first square rotating shaft 6 to rotate, and the circular rotating rod 91 drives the circular rotating disk 12 to rotate. When the circular rotating disk 12 rotates, it drives the end of the connecting rod 13 to move, and the other end of the connecting rod 13 pulls the fixing rod 14 to slide on the outer wall of the first sliding rod 15, so that the collecting frame 17 can also move; the moving collecting frame 17 will shake the pressed material constantly to avoid the accumulation of pressed materials; after completing the work, turn off the equipment switch, remove the screws 16 of the collecting frame 17 and the fixing rod 14, and the collecting frame 17 is separated from the stamping equipment, and the pressed materials that have been stamped can be taken out; the rotating handle 24 is rotated counterclockwise, the screw rod 23 moves, and the two groups of support frames 25 move in the opposite direction on the second sliding rod 26, and the second bracket 8, the rotating wheel 10 and the conveyor belt 11 combined with the support frame 25 move to both sides together until the support frame 25 is separated from the lower template 18, and the rotating handle 24 is stopped; replace the lower templates 18 of different models, and start the pressing work of different models.
