Hand-cranking pulse turning correction control system of cold header

Abstract

The invention discloses a hand-cranking pulse turning correction control system of a cold header, and belongs to the field of machining equipment so as to reduce wear to a pneumatic clutch, reduce turning correction noise and increase turning correction precision. Control equipment comprises a frequency converter, a hand-cranking encoder is connected with the frequency converter, and the control equipment is connected with a main motor. The main motor is connected with a flywheel through a belt. The pneumatic clutch is arranged on the flywheel. The flywheel is connected with a main transmission crankshaft through the pneumatic clutch. The main transmission crankshaft is connected with a transmission mechanism. The transmission mechanism comprises a main sliding table, and a mold is arranged on the main sliding table. The main motor operates and can drive the flywheel to operate. The pneumatic clutch arranged on the flywheel is connected with the main transmission crankshaft, the pneumatic clutch and the flywheel can be in two states including engagement and disengagement, and therefore the motion state of the main transmission crankshaft is controlled. The main transmission crankshaft can drive the main sliding table to move, and the main sliding table and the mold arranged on the main sliding table are subjected to turning correction. The hand-cranking pulse turning correctioncontrol system is mainly used for carrying out precise turning correction on the cold header.

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
