Once-forming extruding machine for tubular axle blank of heavy truck

Abstract

The invention discloses a once-forming extruding machine for a tubular axle blank of a heavy truck and belongs to the field of equipment manufacturing. The machine comprises a rack, left and right horizontal thrust oil cylinders, left and right extrusion forming dies, a clamping oil cylinder and upper and lower clamping dies. The rack is of a T-shaped steel-structure framework; the left and right horizontal thrust oil cylinders are mounted at the left and right ends of the rack respectively; and the left and right extrusion forming dies are connected with piston rods of the left and right horizontal thrust oil cylinders respectively. The clamping oil cylinder is vertically mounted at the upper end of the middle part of the rack; the upper clamping die is connected with the piston rod of the clamping oil cylinder; and the upper clamping die is connected with the rack through a guide sleeve of a guide rod. The lower clamping die is mounted at the lower part of the rack. Sliders are arranged between the horizontal thrust oil cylinders and the extrusion forming dies; and the sliders are connected with the rack through a sliding guide rail and a wheel-type guide rail. The once-forming extruding machine disclosed by the invention has the advantages that the axle blank has high strength, the manufacturing processes of the axle blank are reduced, the production rate is improved, the blank material is easily prepared and can adopt a round pipe, and the material is saved.

Description

technical field [0001] The invention relates to special equipment for processing automobile axle blanks, in particular to an extrusion machine for processing shrinkage holes at both ends of tubular axles. It can also be used for the processing of other similar tubular parts blanks. Background technique [0002] At present, in the manufacturing process of axle blanks, the processing of multiple shrinkage cavities at both ends mostly adopts welding technology, which is complicated and labor-intensive. If the treatment is not good, there will be welding defects, sand inclusions, poor welding strength, and fractures during use, posing safety hazards. If the welding stress is not well handled, it is easy to deform, and the accuracy and concentricity are difficult to guarantee. Contents of the invention [0003] In order to solve the above-mentioned technical problems, the present invention provides a heavy-duty automobile tubular axle blank one-time forming extruder. And the...
