[0002] Cutting metal rods is a common operation in metal processing.

[0003] However, during the cutting process, the metal rod often shifts due to factors such as cutting force and vibration. This shift significantly affects cutting accuracy, resulting in large dimensional errors in the finished products, failing to meet production requirements, increasing scrap rates, and raising production costs. Therefore, we propose an adjustable positioning metal product cutting device. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: an adjustable positioning metal product cutting device, including a worktable, a cutting machine fixedly installed on the top of the worktable, and a clamping component and an extruding component also installed on the worktable;

[0006] The clamping component includes a limiting seat, the top of which has an arc groove that fits against the surface of the metal rod, clamping strips are movably installed at both ends of the top of the limiting seat, and adjusting components for adjusting the position of the clamping strips are fixedly installed on both sides of the limiting seat. The bottom of the limiting seat has several evenly spaced recessed grooves, and a rolling component is rotatably installed in each recessed groove, with the rolling component protruding outside the recessed groove.

[0007] The extrusion component includes an arc-shaped pressure plate that can move up and down along the Y-axis. The arc-shaped pressure plate and the limiting seat are arranged vertically opposite each other, and the bottom side of the arc-shaped pressure plate is an arc surface that fits against the surface of the metal rod.

[0008] Several self-rotating ball bearings are installed on the facing surfaces of the clamping bars on both sides and the bottom side of the arc-shaped pressure plate, and the ball bearings are evenly spaced.

[0009] The arc-shaped pressing plate in the extrusion piece can exert pressure on the metal stick from above under the action of the electric push rod, and forms a limiting effect in cooperation with the clamping piece below. The all-around fixing mode can effectively resist external forces such as cutting force and vibration which cause the metal stick to deviate, and ensures that the metal stick remains stable during the cutting process. In the cutting process, the rolling piece and the ball piece cooperate to disperse the friction force generated by the cutting force, reduce the possibility of the metal stick deviating due to excessive local friction force, and further improve the stability of positioning.

[0010] Preferably, a driving piece is fixedly installed on the side wall below the clamping piece, and the top of the driving piece is in contact with the bottom of the rolling piece.

[0011] Preferably, the rolling piece comprises a plurality of rotating rods, a plurality of cylindrical blocks are rotatably installed on the outer side of the rod wall of the rotating rod, the cylindrical blocks are made of rubber material, and a plurality of groups of clamping grooves are arranged in an annular array on the outer wall of the cylindrical block.

[0012] Preferably, the driving piece comprises two support plates, the driving rods are rotatably installed on the surface of the two support plates, a first gear is fixedly arranged at the end of the driving rod away from the cutting machine, a second gear is connected to the bottom of the first gear, and a driving motor combined with the workbench is fixedly connected to the side surface of the second gear.

[0013] Preferably, the diameter of the driving rod is the same as the diameter of the cylindrical block, and the outer wall of the driving rod is annularly arrayed with clamping blocks corresponding to the positions of the clamping grooves.

[0014] Preferably, the extrusion piece comprises electric push rods fixedly arranged on both sides of the clamping piece, the two electric push rods are located at the two ends of the clamping piece, a connecting plate is fixedly arranged at the top end of each electric push rod, and the top ends of the two connecting plates are fixedly connected with the bottom of the arc-shaped pressing plate.

[0015] Preferably, the adjusting piece comprises a threaded tube and an adjusting plate fixedly arranged on the limiting seat and the clamping strip respectively, an adjusting rod is threadedly connected to the side wall of the adjusting plate, and a limiting ring is fixedly arranged on the rod wall of the adjusting rod and in contact with the side surface away from the threaded tube.

[0016] Preferably, an elastic clamping piece is fixedly arranged on the side surface above the threaded tube, and a plurality of limiting grooves are arranged in the bottom side surface of the adjusting plate and matched with the top end of the elastic clamping piece.

[0017] Compared with the prior art, the utility model has the advantages that:

[0018] 1. This utility model utilizes an arc-shaped pressure plate in the extrusion component, which, under the action of an electric push rod, applies pressure to the metal rod from above, creating a coordinated upper and lower limiting effect with the clamping component below. This all-around fixing method effectively resists external forces such as cutting force and vibration that could cause the metal rod to shift, ensuring its stability throughout the cutting process. During cutting, the rolling components and ball bearings work together to disperse the frictional force generated by the cutting force, reducing the possibility of the metal rod shifting due to excessive local friction, further improving positioning stability.

[0019] 2. This utility model also enables the rolling element at the bottom of the limiting seat to rotate through the setting of the driving component. The frictional resistance can drive the metal rod to rotate during the cutting process. The rotation can make the contact point between the cutting machine and the metal rod constantly change, avoiding problems such as skewed cuts and serrated edges caused by uneven local force during the cutting process. This makes the cut more flat and smooth, improving the quality of the cut surface. At the same time, when the metal rod rotates, the chips generated during cutting are more easily discharged from the cutting area, avoiding chip accumulation at the cutting point. This reduces the obstruction of the cutting tool by chips, making the cutting process smoother and improving cutting efficiency.

[0020] 3. The several sets of locking grooves constructed on the cylindrical block in this utility model can form a concave-convex fit with the metal rod when compressed, thereby increasing the resistance to the lateral movement of the metal rod, further reducing the lateral movement of the metal rod during the cutting process, and enhancing the cutting stability.
