Punching line of automobile door pillar and panel workpieces and mechanical arms for punching line

Abstract

Disclosed are a punching line of automobile door pillar and panel workpieces and mechanical arms for the punching line. A plurality of presses (2) are linearly arranged at equal intervals. Each punching die assembly (3) is provided with an outer plate cavity and an inner plate cavity; a transverse rod (4) crosses the whole punching line; the transverse rod (4) can be driven to move up and down by a vertical drive mechanism; the transverse rod (4) is sleeved with a sliding sleeve (5); the sliding sleeve (5) can be driven to move side to side along the transverse rod (4) by a transverse drive mechanism; the sliding sleeve (5) is provided with the mechanical arms (6) on the left and right sides of each press (2); the mechanical arms are used for gripping and moving automobile door pillar and panel outer plates and inner plates (1) at respective positions; a turnplate (8) on which a plurality of bed plates (9) are evenly arranged is disposed at the left end; an inner plates and outer plates holder (10) is disposed on each bed plate (9). The punching line and the mechanical arms have the advantages that automatic punching level of automobile door pillars and panels is increased greatly, and punching efficiency of the automobile door pillars and panels is greatly improved.

Description

technical field [0001] The invention relates to a stamping production line for car door pillar plate workpieces and a mechanical arm thereof. 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, and the arc is also formed during rolling; it is cut into workpieces to be stamped before rolling off the production line, and then After multiple stamping processes, it becomes a part that can be assembled into the front and rear door frames of a car. like figure 1 , figure 2 Shown are the rear door B-pillar outer panel and the rear...

AI Technical Summary

Problems solved by technology

[0003] In the prior art, the outer panel and the inner panel of the above four types of door pillar panels need to be stamped through multiple processes respectively. There are a large number of stamping dies to be developed, and a large number of presses and stamping operators are equipped. The degree of automation and production Efficiency and stamping quality have been difficult to effectively break through; and stamping operations, as long as the traditional operation method of manually completing the work of sending and taking workpieces in the press is adopted, the personal safety of the operator is difficult to control, and accidents often occur frequently
