Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

It should be noted that, in the description of the present invention, the terms "first", "second", and the like are used for descriptive purposes only and for distinguishing similar objects, and no order is shown between the two, and no indication or suggestion of relative importance is understood. In addition, in the description of the present invention, "a plurality" means two or more unless otherwise specified.

With reference to fig. 1 to 4, the present embodiment discloses a single-side double-line rotary shearing mechanism for butt-jointing a two-line cutting and rolling process in the prior art, so as to shear two bar-shaped rolled pieces under the condition of using one set of mechanism. The diameter of the rolled piece is usually 8-20mm, and the material is usually metal.

In this embodiment, the mechanism includes a body 1, a drive assembly, and two trim assemblies 2. The body 1 is provided with an installation cavity and is positioned at the rear side, and the driving assembly is arranged in the installation cavity and can be respectively connected with the two shearing assemblies 2. The driving assembly can drive the two shearing assemblies 2 to synchronously rotate in a manner of meshing the driving gear and the driven gear, and the corresponding rolled piece is sheared.

In the embodiment, the two shearing assemblies 2 are positioned on the front side and are arranged oppositely along the vertical direction, so that the effectiveness of shearing the rolled piece is ensured. Wherein every cut material subassembly 2 all includes be discoid installation body 21, along six material portions of cutting that the circumference equipartition of installation body 21 set up. The arrangement mode can shorten the time interval between the two cutting stations of the mechanism, and further continuously and quickly perform cutting action on the rolled piece.

The material shearing parts of the two material shearing assemblies 2 are provided with gaps in the vertical direction, the size of the gap is smaller than the diameter of a rolled piece and can reach 0.1-0.3mm, so that the upper and lower corresponding material shearing parts can be respectively abutted against the rolled piece, and further effective shearing action is completed. In addition, the gap of 0.1-0.3mm can make the cut material smoothly fall off from the cutter 22, so as to avoid the residual cut rolled piece on the cutter 22 to affect the subsequent operation; but also can ensure the attractive shearing surface of the bar rolled piece and improve the section quality of the bar rolled piece.

In this embodiment, each material shearing portion includes two cutters 22 arranged at intervals in the front-rear direction, wherein the action portions of the cutters 22 are arranged toward the rolled piece. In order to satisfy the requirement that the two cutters 22 can be disposed at one cutting station, one embodiment is to increase the width of the mounting body 21, and the other embodiment is to use two mounting portions which are stacked and relatively fixedly disposed to constitute the mounting body 21. Because two rolled pieces have certain clearance in the process of discharging because the influence of factors such as size, for example satisfy the above-mentioned rolled piece does not need the requirement in clearance in this mode, two relative distance between the cutter 22 can be adjusted, and one of them mode is seted up on the installation body 21 along its axial direction upwards extend and supply the guide groove body that cutter 22 stretched into.

It should be noted that, during the process of conveying two rolled pieces, due to the mechanical assembly fit, mechanical vibration and other factors, deviation of the preset position may occur, which may cause the cutting knife 22 not to be in effective contact with the rolled pieces, and further cause failure of the shearing action. In view of the above problems, in this way, on the one hand, a hollow tubular guide is provided at the feed inlet of the device to correct the delivery position of the rolled piece, and on the other hand, the ratio between the width of the active portion of the cutting knife 22 and the width of the piece is set, preferably between 2 and 4, which effectively ensures effective contact between the cutting knife 22 and the rolled piece. It should be noted that, since the relative distance between the two cutting blades 22 can be adjusted, the positions of the cutting blades 22 can be adjusted adaptively according to the shaking amplitude of the rolled piece under the error caused by the mechanical vibration and the like.

The ratio is set so that the size of the cutter 22 can be effectively controlled while the rolled piece can be effectively sheared, and therefore the required installation space is reduced.

Referring to fig. 2 to 4, a mounting cavity is concavely formed on the surface of the mounting body 21, and a locking member 23 capable of being locked on the mounting body 21 and the cutting blade 22 are arranged in the mounting cavity. The locking piece 23 is abutted against the cutting knife 22, the inner side wall of the mounting body 21 is abutted against the cutting knife 22, and the mechanical cooperation is used for fixing the cutting knife 22 relative to the mounting body 21.

In one embodiment, a first groove 24 is formed on a side surface of the locking member 23, an upper end of the first groove 24 extends to an upper surface of the locking member 23, and a lower end extends to a lower surface of the locking member 23. And a second groove is formed in the first side surface of the cutter 22, and the second side surface is abutted to the inner side wall of the seal pressing body 1. The cutter 22 can be embedded into the first groove 24 and attached to the side wall of the locking member 23, the front side wall and the rear side wall of the cutter 22 can be abutted to the inner side wall of the locking member 23 respectively, and mechanical limitation of the cutter 22 is completed in the axis direction of the installation body 21. The lower end part of the locking piece 23 can be embedded into the second groove and is abutted against the lower end wall of the second groove, the locking piece 23 is locked on the mounting body 21, and then the mechanical limit of the cutter 22 is completed in the radial direction of the mounting body 21. The combination of the two can lock the cutters 22 under the locking of an external bolt or screw, the installation and the disassembly are convenient, and especially under the condition that the number of the cutters 22 is large, the limitation is more prominent.

In another embodiment, two locking members 23 are provided, and two locking members 23 are respectively disposed at two opposite sides of the cutting knife 22, wherein the structures of the locking members 23 and the cutting knife 22 are the same as or similar to those of the above-described embodiment.

The present invention has been explained by using specific embodiments, and the explanation of the above embodiments is only used to help understand the method and the core idea of the present invention; meanwhile, for the general technical personnel in the field, according to the idea of the present invention, there are changes in the specific implementation and application scope, to sum up, the content of the present specification should not be understood as the limitation of the present invention.
