Disposable forming die for a plurality of bosses at end part

Abstract

The invention relates to a disposable forming die for a plurality of bosses at the end part, which comprises a plurality of sets of upper and lower clamping dies, connection screws and return springs, wherein the clamping dies in a plurality of sets of upper and lower clamping dies are symmetric respectively relative to a central line; each connection screw is an internal hexagonal screw which is screwed down to a bolt countersink. The depth of the bolt countersink cannot be less than the sum of the height of the countersink of the internal hexagonal countersink head screw and the amount of clearances of the corresponding clamping dies. The first clamping die is used as a die seat; the widths of other clamping dies are equal to the distance among the bosses of the product; the amount of the clearances among the clamping dies is equal to the forming amount of the sizes of the bosses of the product; all the clamping dies are connected through the connection screws; simultaneously, the return spring for ensuring the amount of the clearances among the clamping dies is arranged in the connection clearance of each clamping die; and the last boss is produced by directly punching a punch die. The die disclosed by the invention has the advantages of reasonable and simple design structure, convenience for use, high production and use efficiency and the capabilities of improving the product quality and finished product ratio and greatly reducing the production cost.

Description

technical field [0001] The invention relates to a mold preparation technology, in particular to a mold for one-time molding of multiple bosses at the end of a metal pipe. Background technique [0002] At present, when the production of metal pipe products involves multi-boss molding at the end, most of them are processed by using a single-boss mold in multiple processes or using a single-boss mold in a multi-station equipment. This requires the adjustment of each mold feed on the equipment one by one to ensure the distance between the bosses at the end of the product, which is time-consuming and poor in accuracy, thus restricting the improvement of production efficiency and production quality of similar products. Contents of the invention [0003] Aiming at the above-mentioned shortcomings, the present invention provides a multi-boss end one-time molding die, which includes: multiple sets of upper and lower clamping dies, connecting screws and return springs.

[0002] At present, when the production of metal pipe products involves multi-boss molding at the end, most of them are processed by using a single-boss mold in multiple processes or using a single-boss mold in a multi-station equipment. This requires the adjustment of each mold input on the equipment one by one to ensure the distance between the bosses at the end of the product, which is time-consuming and poor in accuracy, thus restricting the improvement of production efficiency and production quality of similar products
