Horizontal type planet powerful spinning machine with four spinning rollers

Abstract

A horizontal type planet powerful spinning machine with four spinning rollers is applied to the press working industry and comprises a main motion oil cylinder, a main motion sliding block, a front and back center frame, a material return device, a planet four-wheel spinning device, a supporting bearing block, a transmission device, a main motor, a supporting frame, a lathe bed, a tail ejection device and a tail ejection oil cylinder. The main motion oil cylinder is connected with the main motion sliding block, the front and back center frame and the material return device are connected with the planet four-wheel spinning device, the supporting bearing block is connected with the transmission device and mounted on the lathe bed, the transmission device is connected with the main motor, and the tail ejection device is connected with the tail ejection oil cylinder. Multiple adjustable material supporting devices are arranged on the lathe bed of the spinning machine, so that tube blanks are prevented from deforming due to self weight, a centering mechanism is arranged at the front end of the tail ejection device and plays a role in centering a core die, a planetary rotating device can conduct stepless speed regulation under dragging of a DC machine, the oil cylinders at the front end and the rear end synchronously move in the axial direction for stepless speed regulation, and four spinning rollers of a four-spinning-roller rigidity synchronizer adjust the feed distance and iso-wall thickness spinning of the spinning machine mechanically and synchronously.

Description

technical field [0001] The invention relates to a horizontal planetary four-rotor powerful spinning machine in the pressure processing industry. Background technique [0002] At present, some progress has been made in the research and development of spinning equipment in the pressure processing industry. But now the design and manufacture are generally traditional spinning machine structure equipment. Spinning technology is a kind of metal pressure forming technology with less cutting and no cutting, and the powerful thinning spinning technology is developing rapidly. In the traditional strong spinning machine, the main shaft drives the mandrel and the blank to rotate, and two or three spinning wheels distributed radially radially press the blank and move along the axis of the blank, so that the wall thickness of the tube blank is thinned and the axial direction is extended. . However, for large-diameter, super-long and thick-walled tube blanks, the moment of inertia is v...

Problems solved by technology

[0003] The purpose of the present invention is to provide a horizontal planetary four-roller powerful spinning machine. This equipment realizes that the heavy-duty tube blank and the mandrel do not perform rotary motion, but only linear motion. The four rotary wheels perform planetary motion around the tube blank. The moment of inertia is small and the forming effect is good. It solves the spinning problem of large-diameter, super-long and thick-walled tube blanks in existing spinning equipment. The super-long-diameter tube blank is heavy and the straightness is not good. The rotation will produce a large moment of inertia. and centrifugal force, the problem of damage to equipment
