[0021] The following will be combined with the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] Example 1

[0023] like Figures 1 to 3 As shown, this embodiment provides a cutting device for a cold heading machine, comprising a cold heading machine body 1, a round material 2 being provided at one end of the cold heading machine body 1, a transverse cutter 3 for cutting the round material 2 being provided at one side of the round material 2, and a moving mechanism for moving the transverse cutter 3 being provided at one side of the cold heading machine body 1;

[0024] A U-shaped support frame 11 is provided on the outer side of the bottom of the round material 2, and a clamping mechanism for clamping the outer side of the round material 2 is provided inside the U-shaped support frame 11;

[0025] The moving mechanism includes an arc-shaped mounting block 5, which is fixed to one side of the cold heading machine body 1. A longitudinal hydraulic cylinder 6 is fixed inside the arc-shaped mounting block 5, and a rectangular moving block 7 is fixed to the output end of the longitudinal hydraulic cylinder 6. The outer side of the transverse cutter 3 is slidably connected to a vertical rectangular block 4. The vertical rectangular block 4 is close to one end of the cold heading machine body 1 and is fixedly connected to the vertical rectangular block 4.

[0026] An oblique guide groove is provided inside the rectangular moving block 7, and a vertical guide column 8 is fixed inside the transverse cutter 3. The vertical guide column 8 is located inside the oblique guide groove and is slidably connected to the transverse cutter 3 through the oblique guide groove. The operation of the longitudinal hydraulic cylinder 6 enables the rectangular moving block 7 to move. The movement of the rectangular moving block 7 enables the transverse cutter 3 to slide inside the vertical rectangular block 4 through the setting of the oblique guide groove, thereby enabling the transverse cutter 3 to move toward the outside of the circular material 2, thereby enabling the transverse cutter 3 to cut the circular material 2;

[0027] A transverse through-slot is provided inside the vertical rectangular block 4. The transverse cutter 3 is located inside the transverse through-slot and is slidably connected to the vertical rectangular block 4 through the transverse through-slot. The transverse through-slot enables the transverse cutter 3 to slide inside the vertical rectangular block 4, thereby enabling the vertical rectangular block 4 to limit the movement trajectory of the transverse cutter 3.

[0028] Example 2

[0029] like Figures 4 to 6 As shown, based on the same concept as the above embodiment 1, this embodiment also proposes a clamping mechanism;

[0030] In this embodiment, the clamping mechanism includes a bottom support column 9, which is fixed to one end of the cold heading machine body 1, and a first jacking hydraulic cylinder 10 is fixed to both ends of the top of the bottom support column 9. The output end of the first jacking hydraulic cylinder 10 is fixedly connected to the U-shaped support frame 11, and a second jacking hydraulic cylinder 12 is fixed to both ends of the inside of the U-shaped support frame 11. The output end of the second jacking hydraulic cylinder 12 is fixed to a U-shaped lifting frame 13, and a third jacking hydraulic cylinder 14 is fixed to both ends of the inside of the U-shaped lifting frame 13. The output end of the third jacking hydraulic cylinder 14 is fixed to a horizontal lifting column 15, and the two sides of the top of the horizontal lifting column 15 are rotatably connected to an oblique rotating column 16 through a pin shaft;

[0031] The top of the oblique rotating column 16 is rotatably connected to a transverse connecting column 17 via a bearing, and a plurality of arc-shaped clamping claws 19 are fixed to the outer side of the transverse connecting column 17;

[0032] A transverse rotating shaft 18 is fixed inside the arc-shaped clamping claw 19 and on the top of the transverse connecting column 17. The transverse rotating shaft 18 is located inside the U-shaped lifting frame 13 and is rotatably connected to the U-shaped lifting frame 13 through a bearing, thereby enabling the arc-shaped clamping claw 19 to rotate around the transverse rotating shaft 18 as the center of the circle, so that the two arc-shaped clamping claws 19 can clamp the outer side of the round material 2;

[0033] The operation of the first jacking hydraulic cylinder 10 enables the U-shaped support frame 11 to be raised and lowered, so that the U-shaped support frame 11 can fit with the outer side of the bottom of the round material 2. The operation of the second jacking hydraulic cylinder 12 enables the two arc-shaped clamping claws 19 to be located on the outer side of the round material 2. The operation of the third jacking hydraulic cylinder 14 enables the transverse lifting column 15 to descend. The descent of the transverse lifting column 15 enables the arc-shaped clamping claws 19 to rotate around the transverse rotating shaft 18 as the center of the circle through the transverse connecting column 17, so that the arc-shaped clamping claws 19 on both sides of the top of the transverse lifting column 15 can clamp the round material 2, thereby fixing the round material 2.

[0034] A specific application of the above two embodiments is that the operation of the longitudinal hydraulic cylinder 6 enables the rectangular moving block 7 to move. The movement of the rectangular moving block 7 is configured through the oblique guide groove, so that the transverse cutter 3 can slide inside the vertical rectangular block 4, thereby enabling the transverse cutter 3 to move toward the outside of the circular material 2, thereby enabling the transverse cutter 3 to cut the circular material 2;

[0035] The operation of the first jacking hydraulic cylinder 10 enables the U-shaped support frame 11 to be raised and lowered, so that the U-shaped support frame 11 can fit with the outer side of the bottom of the round material 2. The operation of the second jacking hydraulic cylinder 12 enables the two arc-shaped clamping claws 19 to be located on the outer side of the round material 2. The operation of the third jacking hydraulic cylinder 14 enables the horizontal lifting column 15 to descend. The descent of the horizontal lifting column 15 is through the horizontal connecting column 17, so that the arc-shaped clamping claws 19 can rotate with the horizontal rotating shaft 18 as the center of the circle, and then the arc-shaped clamping claws 19 on both sides of the top of the horizontal lifting column 15 can clamp the round material 2, so that the round material 2 can be fixed.

[0036] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
