Description

Technical Field

[0001] The utility model relates to the technical field of straight punches, and more specifically to an H-shaped straight punch of a stamping die. Background Art

[0002] A straight punch usually refers to a tool used for metal stamping. A straight punch is a type of stamping die, which is used to punch straight holes or holes of other shapes on metal sheets. During the stamping process, the punch applies high pressure to impact the metal sheet, causing the metal sheet to undergo plastic deformation under the action of the die hole, and finally forming the desired hole or convex shape.

[0003] The utility model with announcement number CN210701981U discloses a double-punch H-type punching machine. By setting a positioning notch, a driving motor, a first drill bit and a second drill bit, two groups of protrusion structures are provided on both sides of the H-shaped steel. The protrusion structure is embedded in the positioning notch. The positioning notch can position the H-shaped steel, and the design of the positioning notch can be used for three groups of H-shaped steels of different models. The driving motor drives the third transmission wheel to rotate, and the third transmission wheel drives the first transmission wheel and the second transmission wheel to rotate through the transmission belt. Then, the first transmission wheel drives the first drill bit to rotate, and the second transmission wheel drives the second drill bit to rotate. The piston rods in the first hydraulic rod and the second hydraulic rod structure move downward at the same time, and the first drill bit and the second drill bit can punch two groups of H-shaped steels at the same time, which greatly improves the punching efficiency.

[0004] When the above patent is in use, a first drill bit is fixedly installed on the bottom outer surface of the first transmission wheel, and a second drill bit is fixedly installed on the bottom outer surface of the second transmission wheel. The first drill bit and the second drill bit punch two groups of H-shaped steels at the same time, but it is inconvenient to adjust the positions of the two drill bits, thereby inconveniently adjusting the positions of the punching holes, and the scope of application is small.

[0008] Furthermore, a handle is movably provided at the bottom of the U-shaped plate, and the top of the handle is fixedly connected to the rotating shaft.

[0009] It can be seen that in the above technical solution, it is convenient to drive the rotating shaft to rotate.

[0010] Furthermore, two limit plates are fixedly connected inside the U-shaped plate, and one end of the two limit plates passes through the two tooth plates and the two sliding blocks respectively.

[0011] It can be seen that in the above technical solution, the sliding block slides on the limit plate, which can improve the stability of the vertical tube.

[0012] Furthermore, the pressure plate is provided with a connecting assembly, and the connecting assembly includes a connecting frame, a screw rod and a threaded sleeve.

[0013] Furthermore, the top end of the connecting frame is fixedly connected to the U-shaped plate, the top end of the screw rod passes through the connecting frame, and the bottom end of the screw rod is fixedly connected to the pressure plate, and the threaded sleeve is movably mounted on the connecting frame.

[0017] 1. The utility model drives the mounting plate to move vertically through the hydraulic cylinder, thereby driving the two punching heads and the pressing plate to move vertically, and punches out an H-shaped hole on the metal plate. Turning the handle drives the rotating shaft to rotate, and then drives the gear to rotate. The gear can drive the two tooth plates to move back to back, thereby driving the two sliders to move back to back, and then driving the two vertical cylinders to move back to back. The distance between the two punching heads is adjusted according to demand, and then the pressing plate of corresponding length is replaced, which is convenient for adjusting the position and size of the punching hole, and has a wide range of applications.

[0018] 2. The utility model rotates the punch head to drive the threaded rod to rotate and move downward, thereby moving the threaded rod out of the vertical cylinder, releasing the fixation between the vertical cylinder and the punch head, and repairing and replacing the punch head. Similarly, the punch head can be installed. It is worth mentioning that the shape of the punch head can be rectangular, and the threaded sleeve is rotated and moved away from the screw rod, thereby releasing the fixation between the pressure plate and the connecting frame, and the pressure plate can be replaced and installed. The operation is simple and easy to use. BRIEF DESCRIPTION OF THE DRAWINGS
