The collecting hopper 120 is used to collect the cut materials and debris.

[0033] The inner positioning disc 210 and the outer positioning disc 220 are arranged in layers inside and outside the front of the fixed seat 110. A semicircular groove is formed on the outer side of the outer positioning disc 220. An electric telescopic device 222 is arranged inside the outer positioning disc 220, and the movable end of the electric telescopic device 222 is connected to the inner positioning disc 210. By adjusting the distance between the two positioning discs, the protruding length of the cut part of the bolt can be controlled.

[0034] The inner arc-shaped frame 310 and the outer arc-shaped frame 320 are arranged above the outer sides of the inner positioning disc 210 and the outer positioning disc 220, respectively. The outer sides of the inner positioning disc 210 and the outer positioning disc 220 are both provided with a positioning clamp 230. When the positioning clamp 230 is rotated to the area where the inner arc-shaped frame 310 and the outer arc-shaped frame 320 are located, the inner side surface of the positioning clamp 230 is abutted, thereby fixing the positioning clamp 230, forming a double fixing effect. At the same time, the positioning clamp 230 forms a circumferential clamping and fixing effect on the bolt.

[0035] Preferably, the front of the inner arc-shaped frame 310 is provided with an outer side plate 321, which forms a sandwich between the outer positioning disc 220, and is used as a plate body mechanism for placing the head of the bolt.

[0036] Preferably, the front of the outer positioning disc 220 is provided with a protruding convex ring frame 221 adjacent to the outer ring region, the outer side of which is an annular groove, and is rotationally connected to the side plate 321 in front of the outer arc-shaped frame 320, so that the outer arc-shaped frame 320 moves with the movement of the outer positioning disc 220.

[0037] Preferably, the positioning clamps 230 outside the inner positioning disc 210 and the outer positioning disc 220 are provided with first telescopic connecting rods 231 connected to each other, so that the two coaxially adjacent positioning clamps 230 automatically adapt to the spacing between the two positioning discs.

[0038] Preferably, the inner arc-shaped frame 310 and the outer arc-shaped frame 320 are provided with second telescopic connecting rods 330 connected to each other, so that the spacing between the two arc-shaped frames 310 and 320 follows the adjustment of the two positioning discs, and at the same time, the outer arc-shaped frame 320 is supported.

[0039] Preferably, the positioning clamps 230 are rotationally installed, and the shaft center coincides with the semicircular groove body, the inner arc-shaped frame 310 and the outer arc-shaped frame 320 cover the upper region of the inner positioning disc 210 and the outer positioning disc 220, extend leftward by 10-85 degrees, so that after the bolt is cut and moved out of the covered region of the inner arc-shaped frame 310 and the outer arc-shaped frame 320, it can be automatically discharged under the action of gravity, and extend rightward by 85 degrees, so that the bolt can directly enter the covered region of the inner arc-shaped frame 310 and the outer arc-shaped frame 320 after being placed inside the positioning clamp 230, and be transported for fixing.

[0040] It can be understood that the utility model can continuously feed and discharge the bolts, and automatically position the placement position of the bolts during this period, so as to ensure the cutting accuracy of the bolts, reduce the time consumption of the overall operation, and shorten the production cycle.

[0041] A specific application of the operation process of the embodiment is as follows: first, the bolts are placed in the inner positioning disc 210 and the outer positioning disc 220 by rotating the inner positioning disc 210 and the outer positioning disc 220, and in the process of upward rotation, the bolts are automatically pressed by the inner walls of the inner arc-shaped frame 310 and the outer arc-shaped frame 320, and at the same time, the head plate of the bolt is automatically positioned between the two plate bodies of the outer arc-shaped frame 320 and the side plate 321, and at this time, the other end of the bolt protrudes backward in the inner positioning disc 210, and during this period, the protruding length of the other end of the bolt can be directly adjusted by the electric telescopic device 222, so as to control the cutting size; further, when the bolt rotates to the upper region, it automatically enters the cutting region of the cutting knife 130 for automatic cutting operation, and during this period, the inner arc-shaped frame 310 abuts against the positioning clamp 230, and then abuts against the part of the bolt adjacent to the cutting surface, so that the placement state of the bolt remains stable during the cutting operation, and then after cutting, the bolt rotates to the right region of the inner positioning disc 210 and automatically falls to form discharge after leaving the range of the inner arc-shaped frame 310.
