Operators are injured when accidentally touching the punching head, so that the personal safety of the operators is guaranteed.

The utility model relates to punch press device field discloses nut forming machine precision punch press device, including support, the inner wall fixedly connected with bottom plate of support, the inner wall rotationally connected with the rotating disc of bottom plate, the inner wall sliding connection has a plurality of punch dies of rotating disc, the top sliding connection has a plurality of slide rail blocks of rotating disc, the bottom fixedly connected with motor of support, the top fixedly connected with punch press of connecting frame, the bottom fixedly connected with first punch head, second punch head, third punch head of connecting frame in proper order, the top of bottom plate is provided with fixed assembly. In the utility model, the punch press drives connecting frame to move down, makes the punch head of connecting frame to the raw material punch press, motor drive, indirectly drive the intermittent rotation of grooved wheel, rotating disc, moves to next position through punch die drive raw material simultaneously, so that the nut raw material is always in the punch press of same mould, reaches the effect of more accurate punch press.

The utility model relates to the related technical field of bolt machining equipment, and one embodiment of the utility model provides a wedge-shaped reinforcement type bolt punching machine which comprises a platform and a fixing column, the fixing column is arranged on the surface of the platform, a material changing assembly is arranged on the platform, a driving motor is installed at the top of the fixing column, and a continuous punching assembly is arranged on the fixing column. The continuous stamping assembly comprises a transmission groove, the transmission groove is formed in the fixing column, a pair of stand columns are arranged in the transmission groove, the stand columns are slidably connected with transmission blocks in a sleeving mode, stamping heads are arranged at the bottoms of the transmission blocks, and the stand columns are each sleeved with a first spring. According to the technical scheme, the technical problems that in the running process of a conventional punching machine in the prior art, operators need to conduct manual discharging, operation is tedious, a large amount of manpower and time are consumed, and large potential safety hazards exist are solved.

The application provides a punching device for a metal gear, relates to the technical field of gear shaft hole punching, and comprises a gear chuck limiting mechanism and a punching mechanism. The gear chuck limiting mechanism comprises limiting blocks and U-shaped connecting rods. The limiting blocks are provided in two groups and are respectively arranged in limiting block penetrating holes in an upper pad plate. The two ends of the U-shaped connecting rods are respectively upwardly penetrated through clamping grooves and fixedly connected with the limiting blocks. The punching mechanism comprises a punching cylinder, a U-shaped frame and a punching head. An oblique notch is arranged at one end of the top of the punching head and is downwardly inclined toward one side. The other end of the punching head is connected with an arc-shaped guide plate, and the top end of the arc-shaped guide plate is obliquely inclined toward one side. After the gear chuck moves to the bottom of the punching head, the gear shaft hole bottom end can be polished through the limiting blocks. When the gear chuck moves to the joint groove, the gear can be flipped and unloaded, so that the problems of manual loading and unloading and burrs on the bottom side after the shaft hole is punched are solved.

The utility model discloses a stamping die for nuts, which comprises an upper die assembly and a lower die assembly, the upper die assembly comprises an upper die holder, the bottom of the upper die holder is fixedly connected with an upper die plate, the bottom of the upper die plate is fixedly connected with a punch fixing plate, and the bottom of the punch fixing plate is fixedly connected with a plurality of first punches.
