Trimming deflashing die for subframe left rear mounting seat reinforcing plate

Abstract

The invention relates to a trimming deflashing die for a subframe left rear mounting seat reinforcing plate. The trimming deflashing die comprises an upper die plate, a lower die plate, a lower base plate, an upper fixed plate, an upper base plate, guide pillars and guide sleeves, wherein yawing force prevention devices are connected to the left sides and the right sides of the upper die plate and the lower die plate; the lower fixed plate is fixedly connected to the upper side of the lower base plate; a lower elastic pressing handle is mounted on the lower fixed plate; a discharging plate is connected to the upper end of the lower elastic pressing handle; a male die is mounted in the lower fixed plate and the discharging plate in a clamping way; a combined workpiece detaching device is connected to the middle of the rear side of the male die; upper elastic pressing handles are arranged in the middles of the upper fixed plate and the upper base plate; a workpiece withdrawing device is connected to the lower ends of the upper elastic pressing handles; a hollow cushion is connected to the lower end of the upper fixed plate; a female die is connected to the lower end of the hollow cushion. The trimming deflashing die for the subframe left rear mounting seat reinforcing plate has the advantages that the structural design is reasonable, the operation and control are convenient, the manufacturing and machining are facilitated and the like; the trimming deflashing processing and the automatic workpiece separation of the subframe left rear mounting seat reinforcing plate are realized, the yawing force is eliminated, the dimensional accuracy for trimming deflashing is ensured, and the service life of the die is prolonged.

Description

technical field [0001] The invention relates to the technical field of auto parts processing, in particular to a trimming mold for a reinforcement plate of a left rear mounting seat of a sub-frame. Background technique [0002] Since the upper part of the reinforcing plate of the left rear mounting seat of the sub-frame is uneven and inclined, the lower part of the reinforcing plate of the left rear mounting seat of the sub-frame is concave. During the production and processing of the reinforcing plate of the left rear mounting seat of the sub-frame, The manufacture of the mold is relatively difficult, and when it is trimmed, it is always pressed from the inclined part of the upper part of the reinforcement plate of the left rear mounting seat of the sub-frame, causing the mold to generate lateral force when closing the mold, so that The movement trajectory of the upper mold is deflected, which is easy to damage the mold. The edge of the reinforced plate of the left rear mou...

[0002] Since the upper part of the reinforcing plate of the left rear mounting seat of the sub-frame is uneven and inclined, the lower part of the reinforcing plate of the left rear mounting seat of the sub-frame is concave. During the production and processing of the reinforcing plate of the left rear mounting seat of the sub-frame, The manufacture of the mold is relatively difficult, and when it is trimmed, it is always pressed from the inclined part of the upper part of the reinforcement plate of the left rear mounting seat of the sub-frame, causing the mold to generate lateral force when closing the mold, so that The movement trajectory of the upper mold is deflected, which is easy to damage the mold. The edge of the reinforced plate of the left rear mounting seat of the sub-frame has a large deviation and low precision, which affects the assembly quality of the reinforcing plate of the left rear mounting seat of the sub-frame. In addition, it is relatively difficult to remove the reinforcement plate of the left rear mounting seat of the sub-frame, and it takes a long time to remove the parts, resulting in a relatively low efficiency of trimming processing

[0003] For example, Chinese patent ZL200820168756.7 proposes an anti-lateral force mechanism for a trimming mold. An upper module is fixed on the upper mold, and a lower module is fixed on the lower mold. The upper module and the lower module are fixed by fasteners, and the upper mold When going down, the upper module and the lower module contact and cooperate with each other, so as to limit the upper mold and ensure that the lateral forces generated by the mold during production are balanced with each other, so that the cutting edge, punch and punch sleeve will not be damaged, and the mold can be extended However, this mechanism is only suitable for one-sided trimming processing, while the reinforcing plate of the left rear mounting seat of the sub-frame is trimmed on all sides at the same time, so this mechanism cannot be applied to the left side of the sub-frame In the trimming process of the reinforcement plate of the rear mounting seat, the applicable surface is narrow
