Stamping die for a single-action press

Abstract

The invention provides a stamping die of a single action press. The stamping die of the single action press comprises an upper die and a lower die, and the upper die and the lower die can be respectively arranged on an upper table face and a lower table face of the single action press. The upper die comprises an upper die seat and an upper die core, wherein the upper die core is fixed on an upper die cavity of the upper die seat. The lower die comprises a lower die seat and a lower die core, wherein the lower die core is fixed on a lower die cavity of the lower die seat. The upper die further comprises upper pressing blocks which are arranged in the upper die cavity of the upper die seat and on the periphery of the upper die core, and a plurality of pressing sources which are arranged between the upper pressing blocks and the upper die seat. The lower die further comprises lower externally-pressing blocks which are arranged in the lower die cavity of the lower die seat and on the periphery of the lower die core, and a plurality of limiting columns which are arranged at the bottoms of the lower externally-pressing blocks. According to the stamping die of the single action press, the phenomena of crack and corrugation can be avoided effectively and stamping quality can be guaranteed.

Description

technical field [0001] The invention relates to stamping equipment for automobile sheet metal parts, and in particular to a stamping die for a single-action press. Background technique [0002] Stamping die is a special process equipment for processing materials (metal or non-metal) into parts (or semi-finished products) in cold stamping processing, called cold stamping die (commonly known as cold stamping die). Stamping is a pressure processing method that uses a mold installed on a press to apply pressure to the material at room temperature to cause separation or plastic deformation to obtain the required parts. Presses can be divided into single-action presses and double-action presses. [0003] The stamping and forming of automobile sheet metal parts requires large batches and many processes. Most of them are 3 to 5 processes. Generally, a stamping production line consisting of 4 to 5 presses is required. Common forms of assembly line combination are generally: a produ...

Problems solved by technology

However, the double-action press is more costly and less efficient than the single-action press

And on the single-action press, the product placement direction is reversed relative to the double-action press. During the transfer process from the double-action press to the single-action press, the sheet metal parts will need to be turned 180 degrees. This requires the addition of turning mechanisms or manual work, thereby increasing production costs and labor intensity, and reducing production efficiency
