Hand-cranking pulse turning correction control system of cold header

Abstract

The invention discloses a hand-operated pulse school bus control system for a cold heading machine, which belongs to the field of machining equipment, and is used to reduce wear on a pneumatic clutch, reduce school bus noise, and increase school bus precision. The control equipment includes a frequency converter, the hand-operated encoder is connected with the frequency converter, the control equipment is connected with the main motor, the main motor is connected with the flywheel through a belt, the flywheel is equipped with a pneumatic clutch, and the flywheel is connected with the main drive crankshaft through the pneumatic clutch. The main transmission crankshaft is connected with a transmission mechanism, the transmission mechanism includes a main slide table, a mold is set on the main slide table, the operation of the main motor can drive the flywheel to run, and the pneumatic clutch set on the flywheel is connected with the main transmission crankshaft, and the pneumatic clutch can be in the position of the flywheel. There are two states of clutch, so as to control the motion state of the main drive crankshaft. The main drive crankshaft can drive the main slide table to move, and the main slide table and the molds set on it can be adjusted. Its main purpose is to carry out precise calibration of cold heading machines.

Description

technical field [0001] The invention belongs to the field of machining equipment, in particular to a hand pulse school bus control system for a cold heading machine. Background technique [0002] When the cold heading machine is produced and debugged, it needs to be checked to verify whether the mold is aligned. In order to avoid the trouble caused by the collision, it is necessary to control the sliding table to move slowly to facilitate inspection and debugging. The original school bus control system is to control the pneumatic clutch by jogging, so that the clutch is in the clutch state intermittently, so that the flywheel can't drive the crankshaft and the transmission device to move when it is idling, so as to control the moving distance of the slide table. This school bus method requires the clutch to be constantly switched between the clutch and pull-in states. The frequency of use of the clutch is too high, and the service life is greatly shortened; and it will gener...

The original school bus control system is to control the pneumatic clutch by jogging, so that the clutch is in the clutch state intermittently, so that the flywheel idling cannot drive the crankshaft and the transmission device to move, thereby controlling the moving distance of the slide table

This school bus method requires the clutch to be constantly switched between the clutch and pull-in states. The frequency of use of the clutch is too high, and the service life is greatly shortened; and it will generate huge noise during operation, and the vibration of the clutch will also increase the workpiece of the transmission mechanism. Degree of wear; In terms of control effect, although the moving distance of the sliding table can be controlled according to the time of the clutch state, the instantaneous moving speed is fast, and the moving distance of the sliding table cannot be effectively controlled. The randomness is large and the requirements for the operator are high, which is easy to cause collisions. Waiting for an accident
