[0023] Please see Figure 1-2 This utility model provides a cutting device for non-ferrous metal rolled extrusions, including: a worktable 1, wherein the two ends of the worktable 1 along its length direction are a feeding end and a discharging end, respectively;

[0024] Two sets of transmission rollers 3 are symmetrically arranged on the top side of the workbench 1 near the feeding end, and the lower transmission roller 3 is embedded in the top of the workbench 1 to support the extruded part 6 of non-ferrous metal rolled material. The transmission roller 3 is arranged in a direction perpendicular to the length direction of the workbench 1. The transmission roller 3 is connected to the drive structure and is used to perform frictional transmission of the extruded part 6.

[0025] A mounting frame 4 is provided between the transmission roller 3 and the feeding end. A shearing mechanism 5 is installed inside the mounting frame 4. The shearing mechanism 5 is used to shear the extruded part 6. A clamping and positioning component is provided on both sides of the shearing mechanism 5 to provide appropriate clamping force for extruded parts 6 of different thicknesses and material specifications.

[0026] It should be explained that during use, the clamping force of the clamping and positioning assembly is first set according to the thickness and material specifications of the extruded part 6 of the non-ferrous metal rolled material. Then, the extruded part 6 is fed in from the feeding end of the worktable 1 and is transferred by friction through the transfer roller 3. After being transferred to the correct position, the extruded part 6 is first clamped by the clamping and positioning assembly, and then the extruded part 6 is cut by the shearing mechanism 5. After cutting, the shearing mechanism 5 moves away from the extruded part 6 first, and then moves away from the clamping and positioning assembly to prevent the extruded part 6 from shifting after cutting, which would affect subsequent conveying.

[0027] Specifically, the transmission roller 3 includes fixed seats rotatably disposed at both ends thereon. The fixed seats are connected to the worktable 1. A drive motor is disposed on one side of the transmission roller 3. The drive motor is fixedly connected to the worktable 1 through a mounting base. The drive motor is used to drive the transmission roller 3 to rotate.

[0028] Furthermore, the workbench 1 is provided with limiting protrusions 2 on both sides along its length direction, and the transmission roller 3 and the mounting frame 4 are respectively installed on the top of the limiting protrusions 2.

[0029] Specifically, the limiting protrusion 2 guides and limits both sides of the extruded part 6 to prevent the extruded part 6 from shifting on both sides during transmission, thus affecting the cutting accuracy.

[0030] Furthermore, the shearing mechanism 5 includes: a hydraulic cylinder 7 vertically fixed downward at the middle of the lower end of the mounting frame 4, a blade holder is installed at the lower end of the piston rod of the hydraulic cylinder 7, and a cutter 8 is detachably installed on the blade holder, the cutter 8 being compatible with the specifications of the extruded part 6;

[0031] A lifting seat 9 is installed on the piston rod of the hydraulic cylinder 7, and the cutting part of the cutter 8 passes through the lifting seat 9 and is located below the lifting seat 9; a clamping and positioning assembly is installed at the bottom of the lifting seat 9, and the clamping and positioning assembly is symmetrically arranged around the cutter 8.

[0032] The hydraulic cylinder 7 drives the clamping and positioning assembly and the cutter 8 to move down synchronously, thereby clamping and cutting the extruded part 6 respectively.

[0033] It should be explained that when the extruded part 6 is cut, the hydraulic cylinder 7 drives the lifting seat 9 to move downward. First, the extruded part 6 is clamped by the clamping and positioning assembly, and then the cutter 8 located between the clamping and positioning assemblies quickly cuts the extruded part 6. After cutting, the cutter 8 first leaves the extruded part 6, and then leaves the clamping and positioning assembly to prevent the extruded part 6 from shifting after cutting, which would affect subsequent conveying.

[0034] Preferably, the workbench 1 has a slot corresponding to the cutter 8 for avoiding the cutter 8.

[0035] Furthermore, the clamping and positioning assembly includes: a pressure rod 11 that slides vertically through the lifting seat 9; mounting cavities 10 are symmetrically opened inside the lifting seat 9 on both sides of the cutter 8; the pressure rod 11 passes through the mounting cavity 10; several pressure rods 11 are evenly distributed along the length extension direction of the lifting seat 9; and the lower end of the pressure rod 11 is connected to a positioning plate 12.

[0036] A retaining ring 13 is fixedly sleeved on the rod body of the pressure rod 11 near the bottom of the mounting cavity 10. A support spring 14 is elastically supported between the retaining ring 13 and the top of the mounting cavity 10. The support spring 14 is sleeved on the pressure rod 11.

[0037] The height of the positioning plate 12 is lower than the height of the cutter 8.

[0038] In other words, when the extruder 6 is pressed, the support spring 14 provides a pressing buffer force, which acts on the positioning plate 12 to press the extruder 6.

[0039] Furthermore, the sliding hole of the pressure rod 11 at the top of the lifting seat 9 is a threaded hole, and an adjusting sleeve 15 is threadedly connected to the threaded hole. The pressure rod 11 slides in conjunction with the inner hole of the adjusting sleeve 15.

[0040] The bottom end of the adjusting sleeve 15 is coaxially provided with an annular convex plate, and the supporting spring 14 is located between the annular convex plate and the retaining ring 13.

[0041] In other words, when extrusion parts 6 of different thicknesses or materials are pressed, their longitudinal height can be changed by rotating the adjusting sleeve 15, thereby changing the final pressing force of the positioning plate 12 on the extrusion part 6, so as to avoid the pressing force being too large or too small, which would affect the cutting quality of the extrusion part 6.

[0042] Furthermore, the outer periphery of the top end of the adjusting sleeve 15 has a screw-on structure.

[0043] The screwing structure is polygonal, facilitating the screwing of the adjusting sleeve 15 using a wrench. Specifically, a torque wrench can be used to unify the height of each adjusting sleeve 15.

[0044] Furthermore, a number of limiting rollers are provided between the transfer roller 3 and the mounting frame 4 to guide and limit the extrusion part 6.

[0045] In practice, the clamping force of the clamping and positioning assembly is first set according to the thickness and material specifications of the extruded part 6 of the non-ferrous metal rolled material. Then, the extruded part 6 is fed in from the loading end of the worktable 1 and is transferred by friction through the transfer roller 3. After being transferred to the correct position, the extruded part 6 is first clamped by the clamping and positioning assembly, and then the extruded part 6 is cut by the shearing mechanism 5. After cutting, the shearing mechanism 5 moves away from the extruded part 6 first, and then moves away from the clamping and positioning assembly to prevent the extruded part 6 from shifting after cutting and affecting subsequent conveying.

[0046] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
