Swinging rolling machine with double inclined surfaces

Abstract

The invention discloses a swinging rolling machine with double inclined surfaces. The swinging rolling machine with the double inclined surfaces comprises a rack and a swinging rolling head assembly, wherein the swinging rolling head assembly is arranged on the rack and comprises a main motor, a spindle, an eccentric sleeve, a planetary gear, an inner gear, an upper inclined plate, a lower inclined plate and a swinging head; the main motor is connected with the eccentric sleeve through the spindle; the planetary gear is sleeved in the eccentric sleeve; the eccentric sleeve is connected with the upper inclined plate through a semicircular spindle head at the lower end of the eccentric sleeve and drives the upper inclined plate to rotate; the planetary gear is meshed with the fixed inner gear, is connected with the lower inclined plate through a coupler at the lower end of the planetary gear and drives the lower inclined plate to rotate; the swinging head is connected to the lower end of the lower inclined plate; the inclination of the upper inclined plate is the same with that of the lower inclined plate, but the rotation direction of the upper inclined plate is opposite to that of the lower inclined plate; and the swinging head is driven to perform swinging rolling actions by rotating the upper inclined plate and the lower inclined plate in the different directions. Rolling friction is realized, and a labor-saving rose curve track can be generated. A two-stage force amplifier with double inclined surfaces is adopted, and the force amplifying ratio is increased 53.29 times.

Description

technical field [0001] The present invention relates to an oscillating rolling machine, in particular to a double-slope oscillating rolling machine. Background technique [0002] In 1918, the United States developed a slick rotary forging machine called "orbital forging machine", and obtained a US patent in 1920. In 1926, the United Kingdom developed a rotary forging machine called a "rotary forging machine". In 1966, the first rotary forging machine was produced. The Swiss Bdltec company has developed a spherical rolling machine called "orbital cold forming machine". Professor Marcinny of Warsaw University of Technology in Poland invented the "four-track PXW swing die rolling mill" in 1967, and was the first country in the world to mass-produce swing rolling machines and export them. [0003] In 1973, the Fifth Ninth Research Institute of my country's Ordnance Industry introduced the prototype of the PXW rotary rolling machine produced in Poland. Started research on rota...

AI Technical Summary

Problems solved by technology

Disadvantages: (1) circular track, the rolling cone surface is pressed along the circumference of the material, and the tangential resistance moment AM force is the largest, accounting for more than 80%. The contact area of ​​the rotating head is large and fan-shaped. Large resistance, high power consumption of rolling head (such as 200T-22KW, 160T-45KW, 600-75KW)

(2) The rolling head is in a circular motion, and the material of the rolled part is deformed along the circumferential direction. In this way, the applied rolling force is perpendicular to the radial deformation direction of the material, and the radial deformation force generated is very small. The material deformation is mainly due to the cone The shaped rolling head squeezes the material to the periphery, so it is more laborious: and the edge of the rolled part is prone to cracks, and the product quality is not good

(3) Since the rotation track is a circular track, the rolling head will drive the parts to rotate, which is very dangerous

Disadvantages: (1) It is difficult to manufacture large-area, high-precision, and high-hardness spherical pairs, and the manufacturing cost is high

[0010]The pressure of the rotary roller adopts the hydraulic direct pressure method, and the "direct pressure method" adopts a hydraulic system with a large diameter and high pressure cylinder, and must be equipped with a pressure sensor and a pressure relay , limit switch, speed control valve and many other accessories; (1) The structure is complex and the cost is high; (2) It is difficult to control the pressure and the displacement accuracy of the slider during fine rolling, so it is difficult to process high-precision rotary forging Parts, the phenomenon of mold fracturing and parts scrapping often occurs; (3) The total power of the swing head motor and hydraulic station motor reaches 100KW~270KW, which is still a high energy consumption equipment
