DETAILED DESCRIPTION

[0020] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments.

[0021] Please refer to the drawings in the embodiments of the utility model Figures 1-2 A straightening mechanism for a wire cutting machine comprises:

[0022] The box 1 is provided with through cavities 10 at both ends, the guiding assembly 3 is provided with two groups which are movably connected in the through cavities 10 respectively, the straightening mechanism 2 is movably connected in the box 1, and the straightening mechanism 2 comprises a plurality of straightening assemblies 20, two groups of cylinders 21 and two groups of mounting plates 22, the two groups of mounting plates 22 are fixedly connected on the plane side walls of the cylinders 21 in symmetrical positions at both ends respectively, and the plurality of straightening assemblies 20 are detachably connected with the two groups of mounting plates 22 respectively.

[0023] The straightening mechanism 2 arranged in the box 1 makes the wire pass through the plurality of straightening assemblies 20 and the cylinders 21 at both ends and then pass through the guiding assembly 3 at both ends, through the method that the wire at both ends is subjected to the action of tension and the wire is subjected to the force in different directions by the straightening assembly 20, the purpose of straightening the wire is achieved, meanwhile, through the arrangement of the guiding assembly 3, the wire can be guided to move in a single direction, and the wire will not be bent in the straightening process, it should be noted that the wire needs to pass through the middle position of the cylinder 21, therefore, the middle position of the cylinder 21 needs to be provided with a circular hole for the wire to pass through, but the cylinder 21 itself does not have the function of straightening, therefore, the diameter of the circular hole in the middle of the cylinder 21 can be greater than the diameter of the wire, that is to say, the diameter of the circular hole in the center of the cylinder 21 is the maximum diameter of the wire that can be straightened.

[0024] Specifically, the straightening assembly 20 comprises a straight plate 200, a straightening block 201 and a plurality of connecting bolts 202, through holes one 2000 are arranged at both ends of the straight plate 200, through holes two 2001 are arranged at the middle position, screw holes two 2010 matched with the through holes two 2001 are arranged on the straightening block 201, and arc-shaped straightening holes 2011 are arranged on the side wall away from the straight plate 200 of the straightening block 201.

[0025] Specifically, a plurality of screw holes one 220 matched with the through holes one 2000 and arranged in symmetrical positions are arranged on the two groups of mounting plates 22.

[0026] The straight plate 200 and the through holes one 2000 and the screw holes one 220 thereon are matched with each other to fix the straight plate 200 on the mounting plate 22, so that the position of the straightening assembly 20 is fixed, and then the through holes two 2001 and the screw holes two 2010 are matched to fix the position of the straightening block 201, when the wire passes through the plurality of arc-shaped straightening holes 2011, the wire with a certain arc can be straightened, it should be noted that in order to ensure the straightening effect of the wire, the plurality of straightening assemblies 22 need to be respectively installed on both sides of the mounting plate 22, and the plurality of straightening assemblies 22 are best staggered.

[0027] Specifically, the plurality of arc straightening holes 2011 are placed with scratch-proof sleeves; considering that the wire will inevitably be scratched due to contact and friction with the arc straightening hole 2011 during straightening, in order to avoid scratches on the wire, the straightening assembly 22 is provided with a scratch-proof sleeve matching the arc straightening hole 2011 (the specific parameters of the scratch-proof sleeve can be added, such as material, hardness or softness, and the profile of the sleeve), and in order to further reduce the probability of scratches on the wire, the box 1 is filled with lubricating oil, which acts as a flexible medium to effectively protect the wire (the type and material of the lubricating oil can be supplemented).

[0028] Specifically, the box 1 is provided with a positioning assembly 4, which includes two groups of Ω-shaped bushings 40 and a plurality of limiting plates 41, the plurality of limiting plates 41 are fixedly connected to the inner side wall of the box 1 in a symmetrical position, the Ω-shaped bushings 40 and the limiting plates 41 are provided with positionally symmetrical mounting holes 400, and the inner diameter of the Ω-shaped bushings 40 matches the outer diameter of the cylinder 20; considering that the plurality of straightening assemblies 20 are respectively located at both ends of the mounting plate 22, if the relative position of the straightening mechanism 2 is fixed, the straightening assembly 20 located near the bottom wall of the box 1 will have a poor installation environment, therefore, the positioning assembly 4 is provided, by placing the cylinder 21 between the two Ω-shaped bushings 40 and fixing the Ω-shaped bushings 40 through the limiting plates 41, the positioning mechanism cannot move but can rotate freely, by rotating the cylinder 21 in the Ω-shaped bushings 40, the relative position of the straightening assembly 20 can be changed, which is convenient for installation and replacement of the straightening assembly 20.

[0029] Specifically, the guide assembly 3 includes two groups of guide rollers 30 and two groups of guide shafts 31, the two groups of guide shafts 31 pass through the two groups of guide rollers 30 and are connected with the guide rollers 30 through keys, and the two ends of the two groups of guide shafts 31 are connected to the side wall of the through cavity 10 through bearings, and the curved side walls of the two groups of guide rollers 30 abut against each other; the guide rollers 30 and the guide shafts 31 are used to limit the loosening direction of the wire, so that the wire can only move along the loosening direction, avoiding displacement of the wire in the straightening process in the non-loosening direction, thereby avoiding the bending of the straightened wire.

[0030] Specifically, the box 1 is provided with a cover 11 hinged to the corners of the box 1; considering that the box 1 is filled with lubricating oil, in order to avoid the splashing of lubricating oil, the cover 11 is hinged to one side of the box 1.

[0031] The above merely describes a preferred embodiment of the present application, and the protection scope of the present application is not limited thereto, and any skilled person in the art, according to the technical scheme and the inventive concept of the present application, makes equivalent replacement or change within the technical range disclosed by the present application, which should be covered within the protection scope of the present application.
