Problems solved by technology

[0002] The spline sleeve is a mechanism that is used in pairs to cooperate with the spline shaft. In order to ensure the accuracy of the fit and the stability of use, it is necessary to have high requirements for the processing quality of the spline sleeve, and due to the thin wall of the spline sleeve Requirements, the commonly used processing methods have low precision, often easily cause product deformation during the clamping process, and the cost is high, which is not conducive to production and processing

Abstract

The invention provides a spline housing forming mould. The spline housing forming mould comprises a lower mould base and a concave mould base which is placed on the lower mould base; a groove is formed in the concave mould base and a locating seat is arranged on the groove; a locating hole is formed in the locating seat and a pressing plate is connected in the locating hole in a scalable manner; acone-shaped fixing block is arranged on the pressing plate and a circular hole is formed in the cone-shaped fixing block; a convex mould base is arranged above the groove and a fixing seat is arranged at the bottom of the convex mould base; a locating rod is arranged under the fixing seat and the axis of the locating rod coincides with the axis of the circular hole; the locating rod is matched with the gap of the circular hole and a forming mechanism is arranged around the locating seat in the groove. According to the spline housing forming mould, the extrusion to pipe blanks can be realizedby simple structure matching, so that the high-accuracy forming of a spline housing can be realized, the stability is stronger, the forming efficiency is higher, the service life of equipment is longer and it is applicable to batch production.

Description

Technical field [0001] The invention belongs to the field of spline sleeve forming equipment, and particularly relates to a spline sleeve forming mold. Background technique [0002] The spline sleeve is a mechanism that is used in pairs with the spline shaft. In order to ensure the accuracy of the fit and the stability of use, it is necessary to have higher requirements on the processing quality of the spline sleeve, and due to the thin wall of the spline sleeve It is required that the commonly used processing methods have low accuracy, and tend to cause product deformation during the clamping processing process, and the cost is high, which is not conducive to production and processing. In view of this situation, the present invention proposes a spline sleeve forming die, which realizes the extrusion of tube blanks through simple structural cooperation, and further realizes the formation of the spline sleeve with high accuracy, with strong stability and high forming efficiency. ...
