Description
Technical Field
The invention relates to the technical field of pressing equipment, in particular to special machine pressing equipment and a method.
Background
The pressing device is divided into four types, namely a pressing die, robot roller edge pressing and simple pressing and a special pressing machine. In the door cover line project, the special pressing machine is required by clients to be developed and manufactured abroad, and domestic manufacturers do not have qualification connection.
The forming processes of the special pressing machine and the pressing die belong to mechanical pressing equipment for forming the peripheral ring in a large range simultaneously, and the special pressing machine and the pressing die are characterized by fast production beat, good quality stability and relatively poor flexibility, and are more suitable for mass production with annual production of more than 10 ten thousand; the robot roll edge pressing belongs to equipment for local gradual forming, is characterized by high flexibility, lower production beat and better quality stability, and is more suitable for medium and small batch production with annual output of less than 10 ten thousand.
The special pressing machine has the pressing strength superior to that of the roll edge. The special press-fit machine is formed into a profile facing surface, and the final press section of the roll edge is a straight line facing curve, so that the bigger the flanging height is, the more compaction is possible from the mechanism. Some products with the pressed edges on the curved surface with larger modeling curvature are not suitable for robot roll edge completion, and are more suitable for mechanical pressing completion. In addition, the wave defect is more easily generated in the forming process of the roll edge. According to the reasons, the special pressing machine meets the requirement of products for pursuing high quality. The beat of the special press machine is much higher than that of the roller edge of the robot and is close to the press die. The time is money, which meets the requirement of high efficiency. The pressing action is servo driving, and the pressing times, the action stroke and the like can be set according to the molding requirement of the workpiece. The design of the die is more flexible than that of a die, and 3 times of pressing can be realized. The pressing die needs to be installed on the edge covering equipment for use, and the special pressing machine completes all pressing functions for the pressing die.
Based on the advantages of the special pressing machine, the applicant newly develops a special pressing machine in order to fill the gap in the field of pressing equipment. The invention relates to a servo-driven pressing device for generating a power source for pressing operation, which is a core technology of a special pressing machine.
