A six-cylinder manifold punching die

Abstract

A six-cylinder header pipe punching die comprises a bottom plate and a punch group and a die mandril which are arranged the upper part and lower part of the bottom plate respectively, 6 punches of the punch group are arranged between a pressing plate and a punch clamping plate in parallel, the upper end of the punch clamping plate is connected with a die handle plate, the upper end of the die handle plate is provided with a die handle connected with a punch press, the bottom plate is provided with a middle guide column seat, a left guide column seat and a right guide column seat, the pressing plate and the punch clamping plate are connected with the bottom plate in a sliding manner by guide columns arranged on the middle guide column seat, the left guide column seat and the right guide column seat, die mandril seats are fixedly arranged at two ends of the bottom plate, and the die mandril seats are provided with bayonets for preventing the die mandril from rotation; clamping slots for matching and positioning with the bayonets are arranged at two ends of the die mandril, and the die mandril is movably arranged in the bayonets of the die mandril seats by the clamping slots at two ends; and the die mandril is provided with die holes corresponding to the punches. The six-cylinder header pipe punching die is high in work efficiency, punching concentricity is consistent, workpiece quality is ensured, a workpiece is convenient and fast to replace, service life is long and cost is low.

Description

technical field [0001] The invention relates to a processing equipment for auto parts, in particular to a punching die for a six-cylinder manifold. Background technique [0002] When processing the manifold of the automobile engine, it is necessary to process the connecting holes of the manifold one by one. For example, six round holes are required to be processed for the manifold of the six-cylinder. The centers of the two circular holes are not on a straight line. Although the above-mentioned problems can be overcome by using a high-precision drilling machine, there are problems of complex structure, high price and high cost, which are not suitable for general small and medium-sized enterprises. Contents of the invention [0003] The object of the present invention is to provide a six-cylinder manifold punching die for processing round holes of the six-cylinder manifold, so as to overcome the shortcomings of the above-mentioned prior art. [0004] The technical solutio...
