Automobile steel plate clamp sleeve die and production working procedure of sleeve

Abstract

The invention provides an automobile steel plate clamp sleeve die. The automobile steel plate clamp sleeve die comprises a blanking die and a forming die, wherein two long edges of the bottom of an upper blanking die are provided with fillets; a square hole is formed in the middle of a lower blanking die; the length and width of the upper blanking die are identical with the length and width of the square hole in the lower blanking die; a semicircular through groove with a downward opening is formed in the bottom of an upper forming die; a semicircular through groove with an upward opening is formed in the bottom of a lower forming die; the diameters of the upper forming die and the lower forming die are identical. According to the invention, materials which are cut off are fully utilized, and no raw material is wasted. The invention also provides a production working procedure of a sleeve. The production working procedure of the sleeve comprises the steps: (1) a raw material is cut off by the cutting edges of the fillets of the upper blanking die and is squeezed to form a U-shaped semi-finished product; (2) the U-shaped semi-finished product is squeezed by the semicircular through grooves of the dies. According to the production working procedure of the sleeve, only two steps are needed, processing steps are reduced, operation workers are reduced, and meanwhile, the production cost is reduced.

Description

technical field [0001] The invention relates to a mold for producing bushings and a production process for bushings, in particular to a bushing mold suitable for automobile steel plate clips and a production method for bushings. Background technique [0002] At present, the method of processing the casing is generally to first cut the raw material twice, respectively cut the long side and the wide side to make the required shape and size, and then press twice through the mold. However, the trimmed leftovers are difficult to put to use due to their small size and can only be wasted. Moreover, the entire production process requires four processes, and each process requires workers to perform, which not only makes the processing process long, but is prone to operational errors, and also causes an increase in production costs. Contents of the invention [0003] In view of the above-mentioned defects and problems of the prior art, the purpose of the embodiment of the present i...
