Circumference-symmetrical automatic pressure straightening machine for slender shaft

Abstract

The invention relates to the field of machining, in particular to a circumference-symmetrical automatic pressure straightening machine for a slender shaft. The circumference-symmetrical automatic pressure straightening machine for the slender shaft comprises a positioning plate, a straightening and bearing device and a bearing drive device, wherein the bearing drive device is in transmission connection with the straightening and bearing device; a positioning and pressure-supplying device and a positioning and taking device are arranged on the positioning plate; a loading support table in buttjoint with the straightening and bearing device is arranged in front of the positioning plate; a blanking support table is arranged under the positioning and taking device; a through slot is formed inthe positioning plate; a controller is arranged beside the positioning plate; a contact displacement sensor is arranged on the straightening and bearing device; and under a work state, a sensing endof the contact displacement sensor is in butt joint with the middle part of a rod piece to be straightened. According to the circumference-symmetrical automatic pressure straightening machine for theslender shaft provided by the invention, the rod piece is automatically rotated, so that an effect on comprehensively detecting and straightening the rod piece can be improved; the rod piece is blanked through the blanking support table; and the straightness of the rod piece is detected through the positioning sensor, so that the accuracy and the efficiency on straightening the rod piece can be improved.

Description

technical field [0001] The invention relates to the field of mechanical processing, in particular to a circumferential symmetrical slender axis pressure automatic straightening machine. Background technique [0002] Straightening machine is a device for straightening metal profiles, bars, pipes, wires, etc. The straightening machine uses the straightening roller to squeeze the bar and so on to change the straightness. Generally, there are two rows of straightening rollers, the number of which varies. There are also two-roll straightening machines, which rely on the concave in the middle of the two rolls and the angle change of the hyperbolic roll to straighten materials with different diameters. The main types are pressure straightening machine, balance rolling straightening machine, shoe rolling straightening machine, rotary reverse bending straightening machine and so on.

Problems solved by technology

[0003] At present, when straightening slender rods, the first thing is to place the rods on the base, manually beat and impact the rods, and then observe the straightness of the rods with the naked eye , to realize the straightening operation of the bar, such a straightening method will cause the problems of inaccurate straightening and low work efficiency
