Problems solved by technology
In the processing of the above-mentioned shaping and extrusion shaft sleeves, after each shaping and extrusion treatment, the shaft sleeves must be removed from the extrusion sleeve mold, thus reducing the production efficiency; in addition, the extrusion sleeve mold must be equipped with a demoulding mechanism, thus increasing the manufacturing cost of the mold; in actual production, jamming often occurs due to the failure of the demoulding mechanism, and it takes man-hours to deal with the failure and eliminate the jamming, which increases the overall cost of production; therefore, the existing technology has low efficiency. , high cost, high failure rate problems and deficiencies

The invention discloses a squeezing device for a continuous rapid shaping burnishing sleeve, which comprises a burnishing core mold (1), a punch (2) and a burnishing cover mold (3). The technical scheme is as follows: the device which comprises the burnishing core mold, the punch and the burnishing cover mold saves a mold stripping process and carries out squeezing shaping on a sleeve blank piecein a continuous manner that is characterized by being end to end, ejecting from the top and coming out from the bottom and passing through easily, and the problems and defects of low efficiency, highcost and high failure rate existing in the prior art are solved. The squeezing device for the continuous rapid shaping burnishing sleeve ensures the processing of the shaping burnishing sleeve to achieve the aims of improving the efficiency, reducing the cost and having no failure in the continuous working manner.
Description
technical field [0001] The present invention relates to a process device for the production of shaft sleeves, in particular to an extrusion device for continuously and rapidly shaping and extruding shaft sleeves used in the production of shaft sleeves, capable of continuously and quickly shaping and calendering punched shaft sleeve blanks . Background technique [0002] The bearing pad is a kind of sliding bearing, and the bushing is made into a full cylindrical bearing pad. During the production of the shaft sleeve, the bearing bush composite strip steel is punched and rolled into a cylindrical shaft sleeve blank, and then the shape of the shaft sleeve blank is extruded and shaped by the extrusion device, and the inner and outer cylinder walls are squeezed. Shape the bushing. [0003] The extrusion device in the prior art is composed of a punch, a squeeze die, and a squeeze mandrel. The punch is located on the ram of the punch press, and the squeeze die is located on the ...
