Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
Referring to fig. 1, a blank guide type punching structure has:
a lower die holder body; the female die is arranged on the lower die holder body; the 'female die' is fixed in the lower die body and is used for punching a required shape by matching with the punch.
The pressing plate body is arranged on the upper die and can be matched with the lower die holder body to press the punched parts; the mounting hole is arranged in the material pressing plate body and is obliquely arranged; the inclined arrangement forms the inclined movement of the punch head, and the special large-angle punching is adapted.
The punch is arranged in the mounting hole, and the first end of the punch can extend out of the pressure plate body and is matched with the female die; the "standard punch" functions to punch out the desired shape in cooperation with the "die".
The driving block is slidably arranged in the mounting hole and can drive the punch to move; the upper end of the driving block can extend out of the material pressing plate body; the driving block is used for converting vertical force transmitted by the striking rod into required blanking force.
The upper die holder body can move up and down; and the driving function is realized.
The beating rod is arranged on the upper die base body, can drive the driving block to slide, is reversely locked on the upper die base body through a bolt and is used for transmitting the force of the press in the vertical direction.
The main principle is as follows: the 'driving block' converts the vertical direction into the vertical direction force of the product and transmits the force to the 'standard punch', and then the 'standard punch' is matched with the 'concave die' to perform blanking.
Still be equipped with guide mechanism in the pressure flitch body, guide mechanism includes the guiding axle, and guiding axle and mounting hole adaptation can slide in the mounting hole, and the drift is installed on the guiding axle. The guide shaft is used for fixing the standard punch and providing a motion guide effect for the punch through relative sliding with the pressure plate, and simultaneously transmitting return stroke and pre-pressure of a lower standard spring.
The pressure plate body is also provided with a limit block for limiting the stroke of the driving block. The limiting block mainly plays an auxiliary role, provides return stroke limiting for the driving speed, the guide shaft and the standard punch, provides prepressing limiting for the mechanism, prevents shaking, and locks the part in the pressure plate body.
Still be equipped with return mechanism in the pressure flitch body, return mechanism is the spring, and the spring suit is on the drift, and the first end and the leading axle contact of spring, the second end and the inner wall contact of pressure flitch body. The 'standard spring' is extruded relatively to the pressure plate body through the 'guide shaft' to form a reverse force, and the function is to provide a return force for the whole mechanism.
