Embodiment Construction

[0006] A Paraguayan support ring manufacturing process, which is carried out in the following order of processing steps: (A) blanking: unloading strips suitable for the size of the support ring; (B) rolling: rolling out the support ring ring blank, and weld the rolled blank; (C) one-time heating extrusion: heat the blank to a temperature of 600-700°C, and perform the first extrusion to obtain the large end profile of the support ring; (D) two Secondary heating and extrusion: reheat the blank to a temperature of 600-700°C, and perform a second extrusion to obtain the contour shape of the small end flanging; (E) Turning: clamp the workpiece based on the inner hole and end surface of the small end, The end face of the large end is processed by turning, and the bright band can be seen; the outer diameter of the large end is processed by turning, with a diameter of φ589±0.5mm; Diameter φ472.6±0.5mm; the workpiece is clamped based on the outer diameter and end surface of the large e...

Abstract

The invention discloses a manufacturing process for a Paraguay type supporting ring, which comprises the processing steps of: (A) blanking; (B) edge rolling; (C) first heating extrusion; (D) secondary heating extrusion; (E) turning, namely clamping a workpiece with an inner hole and the end surface of a small end as a reference, and turning the end surface of a big end; turning the outer diameter of the big end, wherein the diameter is phi 589+/-0.5mm; clamping the workpiece with the outer diameter and the end surface of the big end as a reference, and turning the inner diameter of the small end, wherein the diameter is phi 472.6+/-0.5mm; clamping the workpiece with outer diameter and the end surface of the big end as a reference, and turning the contour of an outer profile surface of the workpiece; and clamping the workpiece with the inner diameter of the small end and the end surface of the small end as a reference, and turning the contour of the outer profile surface of the workpiece; (F) removal of sharp corners and blur; and (G) convex hull punching. When the process is used for processing the Paraguay type supporting ring, the product has the advantages of high precision, elegant contour, light weight, and sturdiness and durability. Moreover, the process has the advantages that: investment in equipment is low, processing cost is low, batch processing of products of different sizes can be realized, and cost is recovered at the highest speed and benefit is realized.

Description

technical field [0001] The invention relates to the technical field of support ring manufacturing technology, in particular to a Paraguayan support ring manufacturing process. Background technique [0002] At present, most manufacturers of truck wheel support rings basically adopt the rolled section steel method when manufacturing Paraguayan support rings. The processing cost of this method is high, and the equipment investment is large, which is not suitable for small batch production. Therefore, it is necessary to propose a manufacturing process that can not only reduce the production cost, but also realize the production of various supporting rings in batches. Contents of the invention [0003] The purpose of the present invention is to provide a Paraguayan support ring manufacturing process with low processing cost, high processing precision, low production investment and wide application in batches, aiming at the defects existing in the prior art. [0004] The techn...
