An integrated linkage device for slotting and cutting rods and pipes based on the same hydraulic compensation

Abstract

The invention discloses an integrated linkage device for slotting and blanking of rods and pipes based on the same hydraulic compensation, which belongs to the technical field of machining. Different eccentric positions of different bending directions can be used to drive the blanking slider and the tool slider on both sides of the double dovetail slide table respectively, so that the reverse linkage of the blanking slider and the tool slider can be realized. , that is to say, through the reverse linkage mechanism, the slotting and unloading operations can be realized at the same time, and the slotting and unloading operations are "nearly synchronous", which greatly reduces the working hours, and the operation is simple and convenient. The roller structure of the groove, and then by adopting the new feeding method of continuous contact with the periphery of the roller hammer head, the limitation of the bearing size is solved, and the continuous contact feeding is realized, and the reclaiming operation is omitted, which saves the feeding time.

Description

technical field [0001] The invention relates to the technical field of machining, in particular to an integrated linkage device for slotting and unloading of rods and pipes based on the same hydraulic compensation. Background technique [0002] Low-stress blanking is to apply crack technology to bar (or pipe) blanking. First, a circumferential crack is artificially prefabricated on the surface of the bar (or pipe), and then the bar with the circumferential surface crack is (or pipe) apply a certain external force to make it dynamically separate in the form of low stress brittle fracture. Low-stress bending fracture blanking is recognized as the most promising precision blanking method in the future. It makes full use of the notch effect and bending effect of the circumferential V-shaped groove to achieve brittle fracture of materials at low stress levels and obtain geometry-free Distortion, vertical flat fracture, blank without chamfering. At present, scholars have conduct...

Problems solved by technology

[0003] Before using the existing low-stress blanking machine for blanking, it is necessary to prefabricate V-shaped grooves on the bar (or pipe) in advance, and the slotting and blanking need to be operated on two separate devices, which is cumbersome and increases man-hours; , the existing blanking must be carried out in the blanking bearing, due to the limitation of the size of the general bearing, it has caused great restrictions on the medium and large diameter bar (or tube)

And when using the existing blanking mold to blank medium and large diameter rods and pipes, it is necessary to design and equip a special retrieving device to complete the retrieving, which is cumbersome and increases man-hours

[0004] For the existing low-stress blanking process, V-shaped grooves need to be prefabricated in advance before blanking rods and pipes. However, this method cannot realize simultaneous grooving and blanking. It requires additional equipment, cumbersome operations, and increased man-hours. Thereby causing certain inconvenience and impact on the actual industrial application

Moreover, the existing low-stress blanking machine adopts the bearing hammerhead blanking method. Due to the limitation of the bearing size, there are certain limitations in blanking for medium and large diameter rods and pipes.
