Board upsetting and shaping die

Abstract

The invention discloses a board upsetting and shaping die, belonging to a metal material plasticity shaping die, which solves the problem that the side wall upsetting of a broad part with large wall thickens difference can not be realized by existing die and is applied to upsetting and shaping of bi-layer barrel-type parts with large wall thickness difference. The die consists of an inner slider upper plate, an upsetting punch retainer, an upsetting punch, an upper triangle verge ring, a lower triangle verge ring, a blank holder, an outer slider upper plate, a movable die, a spring housing, alimit spring, an upsetting movable die, a fixed die, an upsetting mandril, a locating ring and a lower plate, the outer slider upper plate is provided with a central holes which are connected with the lower plate via four evenly-distributed guide pillars and guide bushes, and the guide pillars are in slide fit with the guide bushes. The invention has the advantages of simple structure, convenientassembly and disassembly, low cost of processing, assembling and debugging, and high product shaping efficiency, and can realize the side wall upsetting and shaping of the bi-layer barrel-type parts so as to acquire the bi-layer barrel-type structure parts with large thickness difference when being arranged on a common double action drawing press.

Description

technical field [0001] The invention belongs to metal material plastic forming dies, in particular to a sheet material upsetting forming die, which is used for upsetting and forging forming of double-layer cylindrical parts with large thickness difference. Background technique [0002] At present, many cavity parts with large surface area and wall thickness difference, such as housing parts of electronic products, hollow tooth parts and complex disc parts of automobile drive parts, etc., are usually processed by integral casting; Or the processing method of cutting after warm / hot forging; or the thin-walled part and the thicker part are manufactured by multi-process methods such as welding combination and heat treatment. In this way, not only the overall performance is reduced, but also the cost and energy consumption are high, and there are many processes, resulting in low efficiency, which does not conform to the social development trend of energy saving and green manufact...
