DETAILED DESCRIPTION

[0017] Embodiment 1

[0018] like Figure 1-Figure 3 As shown, a cold shearing positioning tool proposed in this embodiment includes: a base frame 1, on which a sliding rail 2 and a top frame 3 are arranged, and a shearing assembly is arranged on the top frame 3. The shearing assembly includes a hydraulic cylinder 4 arranged on the top frame 3, a driving block 5 connected to the output end of the hydraulic cylinder 4, and a shearing knife 51 arranged at the bottom of the driving block 5. The bottom of the shearing knife 51 has a semicircular shearing groove. When the shearing knife 51 falls, the semicircular shearing groove can reduce the movement of the steel rod, thereby improving the shearing quality of cold shearing.

[0019] A fixed component is arranged on the base frame 1, and the fixed component includes a fixed table 9 arranged on the base frame 1, a plurality of clamping blocks 10 slidingly arranged along a ring on the fixed table 9, a moving ring 11 slidingly arranged on both sides of the outer circumference of the plurality of clamping blocks 10, and a driving component driving the two moving rings 11 to move relative to each other. A spring is arranged between the fixed table 9 and the plurality of clamping blocks 10, and the base frame 1 has a sliding groove 101, and the sliding groove 101 gradually tilts downward from the vicinity of the fixed component toward one side of the base frame 1. A collecting frame is placed at the sliding groove 101, and the cut steel will directly slide into the collecting frame, thereby reducing the work intensity of the workers.

[0020] In the present embodiment, when cutting the steel rod, the worker places the steel rod so as to extend between the multiple clamping blocks 10. According to the diameter of the batch of steel rods, the worker controls the driving assembly to move the two moving rings 11. If the diameter of the steel rod is large, the two moving rings 11 move in opposite directions respectively, and the spring drives the multiple clamping blocks 10 to move toward the fixed platform 9, thereby increasing the distance between the multiple clamping blocks 10 to allow the larger steel rod to be fixed. If the diameter of the steel rod is small, the worker drives the two moving rings 11 to move relative to each other, thereby reducing the distance between the multiple clamping blocks 10, thereby improving the versatility of the tooling.

[0021] Embodiment 2

[0022] like Figure 1 and Figure 3 As shown, a cold shear positioning tool proposed in this embodiment, compared with the first embodiment, in this embodiment, the driving assembly includes a handwheel 14 rotatably set on the fixed table 9, a driving rod 15 coaxially connected to the handwheel 14, a plurality of worm gears 16 coaxially set on the driving rod 15, a plurality of bidirectional lead screws 12 threadedly connected on two movable rings 11, and a worm 13 coaxially set on the bidirectional lead screw 12, and the worm wheel 16 is meshingly connected to the worm 13.

[0023] In this embodiment, when driving the movable ring 11, the worker rotates the hand wheel 14, the hand wheel 14 drives the driving rod 15 to rotate, and the driving rod 15 drives the worm 13 to rotate through the worm gear 16. According to the rotation direction of the worm 13, the bidirectional screw 12 drives the two movable rings 11 to move relative to each other or move away from each other, thereby reducing the difficulty of adjustment for the worker.

[0024] Embodiment 3

[0025] like Figure 1 and Figure 2As shown, a cold shear positioning tool proposed in this embodiment, compared with the first embodiment, in this embodiment, preferably, a sliding table 6 is slidably arranged on the sliding track 2, and a plurality of rollers are rotatably arranged on the sliding table 6, and a clamping sleeve 8 is arranged on the outer circumference of the plurality of rollers, and the plurality of clamping sleeves 8 are all made of elastic wear-resistant materials. A counter 7 is arranged on the sliding table 6, and the counter 7 is electrically connected to the rollers.

[0026] In the present embodiment, when cutting the steel rod, the worker first extends the steel rod between the multiple clamping sleeves 8, and the steel rod passes through the multiple clamping sleeves 8 and moves toward the fixed platform 9. During the movement, the counter will display how long the steel rod has been extended according to the number of rotations of the roller. After cold shearing, the worker can compare the length before and after shearing to avoid cutting too much steel rod, thereby reducing the production loss of steel rod.

[0027] The implementation modes of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited thereto, and various changes can be made within the knowledge scope of technicians in the relevant technical field without departing from the purpose of the present invention.
