Technical Field

The invention relates to the technical field of accessories of an open crankshaft punching machine, in particular to an accessory for improving a rotary key type clutch of the open crankshaft punching machine.

Background

The design principle of open crankshaft punching machine is that the circular motion is converted into linear motion, the main motor is used to drive flywheel, the clutch is used to drive gear, crankshaft and connecting rod to make them rotate so as to implement the linear motion of slide block, the motion from main motor to connecting rod is circular motion, and between connecting rod and slide block there is a switching point of circular motion and linear motion, and its design is roughly divided into two mechanisms, one is ball type and one is pin type, and the circular motion is converted into linear motion of slide block by means of said mechanism, and the punching machine can apply pressure to the material to make it be plastically deformed so as to obtain the required form and accuracy, so that it must be matched with a group of mould to place the material between them, and the machine can apply pressure to make it be deformed, and the reaction force resulted from force applied to the material in the course of processing can be absorbed by machine body, and when the open crankshaft punching machine is worked, the motor can be used to drive large belt pulley by means of triangular belt, the crank-slider mechanism is driven by a gear pair and a clutch, so that the slider and the male die move down linearly, the slider moves upwards in a return stroke after forging and pressing work is finished, the clutch is automatically disengaged, an automatic device on a crankshaft is switched on at the same time, the slider stops near a top dead center, the clutch plays a key role in connecting motor power and the slider of the punch press, and the clutch is usually a rotating key type clutch.

The rotary key clutch has two structures of a single rotary key and a double rotary key, and the rotary key type clutch is simple in structure, convenient to manufacture and free of an additional power source. However, the transmission torque is small, the connecting element is easy to damage due to impact load, the sliding block can only stop at the upper dead point and cannot stop at any position of the stroke, once the sliding block controlled by the traditional rotary key type clutch slides in an open mode, the sliding block cannot stop at any time before returning to the upper dead point, and if a user of equipment mistakenly steps on a pedal of a punch press due to improper operation, the safety accident of clamping hands is very easy to happen.
