A stamping die for machining notches on thin-walled tubular parts

Abstract

The invention discloses a stamping die for machining a notch in a thin-wall tubular component, which is short in machining time and low in cost. The stamping die comprises an upper die holder and a lower die holder, wherein a drive block and an insertion tool for driving outer tool aprons to move towards the inner side are arranged on the upper die holder; a left bulged block and a right bulged block are arranged at the both sides of the drive block respectively; a rectangular installation base is arranged on the lower die holder; an inner tool apron, and the left and right outer tool aprons moving along a horizontal direction are arranged in the installation base; the insertion tool is capable of being inserted between the outer tool aprons and the installation base; an inner cutting tool filled in the U-shaped groove of a piece to be cut is arranged on the inner tool apron; outer cutting tools matched with the inner cutting tool are arranged on the outer tool aprons; an installation rod is horizontally installed at one side away from the piece to be cut, of each outer tool apron; the end portion of each installation rod penetrates through the installation base, and is sequentially provided with a compression spring, a limit stop block and a locking nut; a drive cavity is formed in the inner tool apron; a left transmission block and a right transmission block are arranged on the inner tool apron and at the two sidewall surfaces of the drive cavity; a space between the left transmission block and the right transmission block is capable of allowing the drive block to penetrate through.

Description

technical field [0001] The invention relates to a stamping die, in particular to a stamping die for processing notches on thin-walled tubular parts. Background technique [0002] In the production of auto parts, it is often necessary to process notches on thin-walled parts. For example, a U-shaped notch needs to be set at the end on the elbow of the rear axle suspension to be used for welding sleeves and hollow pipes. Due to the requirement that the product cannot produce plastic deformation during the processing, the existing processing method is: after the product is stamped or hydroformed, the notch trimming of the elbow is completed by laser cutting. This processing method consumes a lot of energy, resulting in high cost of parts production; moreover, laser cutting a U-shaped notch of a pipe takes 50 seconds to complete, and the production efficiency is low. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a...
