Automatic punching production line for automobile door frame inner plate and outer plate

Abstract

The invention discloses an automatic punching production line for an automobile door frame inner plate and an outer plate. The automatic punching production line comprises a feeding platform, a first punching machine, an overturning platform, a second punching machine and a mechanical arm. The mechanical arm penetrates through the first punching machine and the second punching machine and is used for moving the inner plate workpiece and the outer plate workpiece to the first punching machine, the overturning platform and the second punching machine in sequence from the feeding platform; the overturning platform is arranged between the first punching machine and the second punching machine and is used for turning over the workpieces taken by the mechanical arm out of the first punching machine by 180 degrees and allowing the mechanical arm to move the turned-over workpieces to the second punching machine. According to the automatic punching production line for the automobile door frame inner plate and the outer plate, the processes from feeding to punching till a finished product is obtained are completely automatically completed, the punching processes before the inner plate and the outer plate of the automobile door frame are turned over are set to one punching machine, all the punching processes after the inner plate and the outer plate of the automobile door frame are turned over are set on the same punching machine, dies on all the punching machines can all perform punching on the inner plate and the outer plate of the automobile door frame simultaneously, manpower and materials are greatly saved, and production efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of processing inner and outer panels of automobile door frames, in particular to an automatic punching line for inner and outer panels of automobile door frames. Background technique [0002] The door pillar panels of a car include the front door A-pillar outer panel and the front door A-pillar inner panel, the front door B-pillar outer panel and the front door B-pillar inner panel, the rear door B-pillar outer panel and the rear door B-pillar inner panel, the rear door C-pillar outer panel and the rear door The inner panel of the C-pillar is generally arc-shaped along with the side wall. At present, it is generally formed by continuous rolling of metal strips. After multiple stamping processes, it becomes a part that can be assembled into the front and rear door frames of a car. The outer panels and inner panels of the above four kinds of door pillar panels are all combined together as parts that can be as...

AI Technical Summary

Problems solved by technology

[0003] At present, the outer panel and inner panel of the above four types of door pillar panels need to be stamped through multiple processes. There are a large number of stamping dies to be developed, and a large number of presses and stamping operators are equipped to ensure the degree of automation and production efficiency. , Stamping quality has been difficult to effectively break through; and the stamping operation adopts the traditional operation method of manually completing the work of sending and taking the workpiece in the press, the operator's personal safety is difficult to control, and accidents often occur frequently; in addition, due to the need for certain parts The arc-shaped concave surface faces upwards for stamping, while some other parts need to be punched with the arc-shaped concave surface facing downwards. Therefore, the workpiece needs to be turned over during the stamping process. At present, the turning of the workpiece is done manually, which is inefficient and labor-intensive. Big

[0004] In addition, the manufacture of the outer panel and inner panel of the automobile door frame requires four stamping processes. The traditional process requires eight punching machines for stamping respectively, and the input of manpower and material resources is relatively high.
