Automatic equal-diameter elbow roundness shaping and cutting all-in-one machine

Abstract

The invention relates to an automatic equal-diameter elbow roundness shaping and cutting all-in-one machine which comprises a main body, a worktable, an upper die plate, a lower die plate and a pressing die cylinder, wherein the worktable is horizontally and fixedly provided with a cylinder in the position corresponding to a port of an equal-diameter semicircular curved furrow composed of the upper die plate and the lower die plate; the tail end of the push rod of the cylinder is fixedly provided with a steel ball string threaded by a steel wire; and the worktable is fixedly provided with a guiding cylinder in which the steel ball string slides; an elevating sawtooth disk is longitudinally arranged in the main body; the lengthwise position of the sawtooth disk corresponds to the port of the equal-diameter semicircular curved furrow composed of the upper die plate and the lower die plate of the worktable; and the worktable is provided with a cutting passage corresponding to the position of the sawtooth disk. The invention has high automation level, integrates the roundness shaping with the end processing allowance cutting, has the advantages of short consumed time for shaping and processing, high working efficiency, high working accuracy, good product quality, conforms to the requirement for product shape roundness, and is suitable for industrial mass production of horn instrument equal-diameter elbows.

Description

technical field [0001] The invention belongs to the field of pipe number musical instrument processing devices, in particular to an automatic equal-diameter bend pipe roundness shaping and cutting integrated machine. Background technique [0002] In the trumpet musical instruments, the equal-diameter bend is an important connecting part. The current processing method of the equal-diameter bend is to weld the copper metal sheet into a tube shape, but the roundness of the tube needs to be processed and shaped to meet the requirements. The requirements of the product, because the roundness directly affects the appearance, tone and sound quality of the pipe number, so the roundness shaping of the equal-diameter bend is an indispensable and important step in the processing of the equal-diameter bend. Most of the existing equal-diameter elbow roundness shaping methods manually press steel balls into the elbow to achieve the purpose of rounding it. This artificial roundness shaping...

Problems solved by technology

However, the existing roundness shaping machine has a low degree of automation and needs manual assistance to complete steps such as hanging ropes, and the efficiency is low; The stress is concentrated, and the rope is easily broken after long-term processing; in addition, after the roundness shaping process of the equal-diameter elbow is completed, the machining allowance at both ends needs to be cut off, and the existing cutting process needs to be done separately. Finished on the cutting equipment, which prolongs the processing time and lowers the processing efficiency
