Vertical lifting flexible feeding system of bar straightening machine

Abstract

A vertical lifting flexible feeding system of a bar straightening machine comprises a beam. A feeding roller way is installed on the beam, and the portion below the beam is connected with guide posts which are placed on bases. The beam is in hinged connection with oil cylinder rods of two lifting oil cylinders which are installed on the bases in a middle trunnion connection mode. A hinge shaft through which the lifting oil cylinders are connected with the beam and the middle trunnions through which the lifting oil cylinders are connected with a left base and a right base are installed in perpendicular crossing mode. One side of a left guide post is respectively provided with two pairs of first spring top rollers, one side of a right guide post is respectively provided with two pairs of second spring top rollers, and the middle trunnions of the lifting oil cylinders and the hinge shaft of the oil cylinder rods are installed in the perpendicular crossing mode, thereby enabling the feeding roller way and the beam to be free in the four directions of forwards, backwards, left and right, ensuring that the feeding roller way and the beam can swing after struck by bars, avoiding excessive impact, prolonging service life and meanwhile reducing work amount of device maintenance.

Description

technical field [0001] The invention belongs to the technical field of bar straightening machines, in particular to a vertical lifting flexible feeding system of a bar straightening machine. Background technique [0002] In the past, most of the feeding mechanisms of straightening machines used fixed roller tables, or used a long tie rod to realize the uniform lifting of the roller tables. When the fixed roller table is used for feeding, because the tail of the bar material swings very much after the bar bites into the main machine, the roller table is strongly impacted, the damage of the roller table is very serious, and the maintenance is very difficult. However, if a full-length tie rod is used for feeding, due to the limitation of the space structure, the lifting height of the roller table is relatively small. At the same time, due to the compression of some rods, there is a problem of stability of the pressure rod, and the assembly accuracy of the cylinder rod and the t...

Problems solved by technology

When the fixed roller table is used for feeding, the tail of the bar swings very much after the bar bites into the main machine, and the roller table is strongly hit, the damage of the roller table is very serious, and the maintenance is very difficult

However, if a full-length tie rod is used for feeding, due to the limitation of the space structure, the lifting height of the roller table is relatively small. At the same time, due to the compression of some rods, there is a problem of stability of the pressure rod, and the assembly accuracy of the cylinder rod and the tie rod is relatively high, otherwise it will be easy. break the cylinder rod
