DETAILED DESCRIPTION

[0023] The present invention is further described below in conjunction with the accompanying drawings and embodiments. The present invention includes but is not limited to the following embodiments.

[0024] like Figure 1-3As shown, the cutting device of the polyetheretherketone modified composite bushing provided by the utility model comprises: a track 1, a mobile platform 2 is installed on the track 1, a driving assembly 3 is installed on one side of the mobile platform 2, the driving assembly 3 is used to drive the mobile platform 2 to move on the track 1, a bushing body 4 capable of self-rotation is installed on the mobile platform 2, a double-wheel cutting assembly 16 is arranged above the track 1, the double-wheel cutting assembly 16 can be raised and lowered, the double-wheel cutting assembly 16 has two cutting wheels, the spacing between the two cutting wheels is adapted to the width of the finished bushing, and the two cutting wheels are used to cut the outer metal layer and the inner polyetheretherketone layer of the bushing respectively, specifically The double-wheel cutting assembly 16 includes a hoisted first electric push rod 10, a connecting frame 5 is installed at the bottom of the first electric push rod 10, a high-speed first cutting wheel 7 and a low-speed second cutting wheel 8 are installed at the bottom of the connecting frame 5, the first cutting wheel 7 and the second cutting wheel 8 are driven by their own driving motors 9, the specifications and rotation speeds of the first cutting wheel 7 and the second cutting wheel 8 and the shapes of the cutting edges are different, so that the first cutting wheel 7 and the second cutting wheel 8 are suitable for cutting the metal outer layer and the polyetheretherketone layer respectively. When in use, under the push of the driving assembly 3, the mobile platform 2 is moved to the bottom of the double-wheel cutting assembly 16, and the top of the mobile platform 2 is moved. The bushing body 4 moves to below the first cutting wheel 7 and the second cutting wheel 8 (in the first cutting, the second cutting wheel 8 will not cut the bushing body 4), the first electric push rod 10 is started, and its output shaft is extended, thereby causing the first cutting wheel 7 and the second cutting wheel 8 to descend. At the same time, the first cutting wheel 7 rotates, the bushing body 4 rotates, and the first cutting wheel 7 descends, performing annular cutting on the bushing body 4 to cut the outer metal layer of the bushing body 4. In the first cutting, the second cutting wheel 8 will not cut the bushing body 4, and then the first cutting wheel 7 and the second cutting wheel 8 rise and break away from the bushing body 4, and the first knife cuts. The mobile platform 2 then moves a fixed distance so that when the second cutting wheel 8 descends, it can be aligned with the position of the blade cut by the first cutting wheel 7 during the first cutting. Then the first cutting wheel 7 and the second cutting wheel 8 descend, and the first cutting wheel 7 cuts the outer metal layer at another position of the bushing body 4. The second cutting wheel 8 cuts along the blade cut by the first cutting wheel 7 to cut the inner polyetheretherketone layer to form a semi-finished bushing. Then the first cutting wheel 7 and the second cutting wheel 8 rise, and the second cutting ends. This cycle continues, and the bushing body 4 can be divided into sections of bushing semi-finished products. Since two different cutting wheels are used to cut the outer metal layer and the inner polyetheretherketone layer respectively, the cutting of the two does not interfere with each other, and polyetheretherketone is not easy to stick to the cutting wheel.

[0025] By setting up a double-wheel cutting assembly 16 including a connecting frame 5, a first cutting wheel 7, a second cutting wheel 8 and a first electric push rod 10, the first cutting wheel 7 and the second cutting wheel 8 are used to cut the metal outer layer and the polyetheretherketone inner layer of the bushing respectively, so that the polyetheretherketone is not easy to stick to the cutting wheel, which is more suitable for the cutting processing of the polyetheretherketone modified composite bushing.

[0026] Embodiment 2:

[0027] like Figure 2 As shown, two slots are provided on the connecting frame 5, and tool holders 6 are installed in the slots. The two tool holders 6 are used to support the first cutting wheel 7, the second cutting wheel 8 and the driving motor 9. A limiting screw 11 is installed on one side of the connecting frame 5, and one end of the limiting screw 11 is pressed tightly on the tool holder 6. When the first cutting wheel 7 and the second cutting wheel 8 are worn and the cutting is not in place, the limiting screw 11 is loosened, the height of the tool holder 6 is adjusted, and then the height difference between the first cutting wheel 7 and the second cutting wheel 8 is adjusted to match the thickness of the metal outer layer, and then the limiting screw 11 is tightened.

[0028] By providing a slot and installing the limit screw 11, the height difference between the first cutting wheel 7 and the second cutting wheel 8 can be conveniently adjusted to facilitate cutting of the bushing.

[0029] Embodiment 3:

[0030] like Figure 1 and Figure 3 As shown, two rotating support rollers 12 are symmetrically installed on the top of the mobile platform 2, the bushing body 4 is placed between the two rotating support rollers 12, and a clamping roller 14 is installed between the two rotating support rollers 12. The clamping roller 14 is installed through the bushing body 4, and the clamping roller 14 can rotate. The clamping roller 14 presses the bushing body 4 downward from the inside so that the bushing body 4 can be restricted to rotate between the two rotating support rollers 12. When in use, the rotating support roller 12 rotates, driving the bushing body 4 to rotate. At the same time, the clamping roller 14 rotates with the bushing body 4.

[0031] By providing the rotating support roller 12 and the pressing roller 14 , the bushing body 4 can be stably rotated on the top of the moving platform 2 .

[0032] Embodiment 4:

[0033] like Figure 3 As shown, a rotating motor 13 is installed at one end of the rotating support roller 12, and the rotating motor 13 drives the rotating support roller 13 to rotate and provides power for it.

[0034] By installing a rotating motor 13 at one end of the rotating support roller 12 , it is possible to conveniently provide power for the rotating support roller 12 .

[0035] Embodiment 5:

[0036] like Figure 3 As shown, two cylinders 15 are installed on the mobile platform 2, and the cylinders 15 are connected to the ends of the pressing rollers 14. When in use, after the bushing body 4 is placed between the two rotating support rollers 12, the pressing roller 14 is passed through the bushing body 4, and its two ends are connected to the cylinders 15. The cylinders 15 are started, and the pressing rollers 14 are pulled down, so that the pressing rollers 14 can more easily press the bushing body 4. It is worth noting that the pressing force of the pressing rollers 14 can be set by setting the pressure of the cylinders.

[0037] By providing the cylinder 15 , the pressing roller 14 can be supported, and the pressure of the pressing roller 14 on the bushing body 4 can be conveniently adjusted.

[0038] Working principle: When in use, the mobile platform 2 is moved to the bottom of the double-wheel cutting assembly 16 under the push of the driving assembly 3, and the bushing body 4 on the top of the mobile platform 2 is moved to the bottom of the first cutting wheel 7 and the second cutting wheel 8. The first electric push rod 10 is started, and its output shaft is extended, so that the first cutting wheel 7 and the second cutting wheel 8 are lowered. At the same time, the first cutting wheel 7 rotates, the bushing body 4 rotates, and the first cutting wheel 7 descends, and the bushing body 4 is cut in an annular manner to cut the outer metal layer of the bushing body 4. During the first cutting, the second cutting wheel 8 does not cut the bushing body 4, and then the first cutting wheel 7 and the second cutting wheel 8 are raised, and the bushing body 4 is cut off. The body 4 is out of contact, the first knife cutting is completed, and then the mobile platform 2 moves a fixed distance, so that when the second cutting wheel 8 descends, it can be aligned with the position of the blade cut by the first cutting wheel 7 during the first knife cutting, and then the first cutting wheel 7 and the second cutting wheel 8 descend, and the first cutting wheel 7 cuts the outer metal layer at another position of the bushing body 4, and the second cutting wheel 8 cuts along the blade cut by the first cutting wheel 7, cutting the inner polyetheretherketone layer to form a semi-finished bushing, and then the first cutting wheel 7 and the second cutting wheel 8 rise, and the second knife cutting is completed, and the cycle continues, and the bushing body 4 can be divided into sections of bushing semi-finished products. Because two different cutting wheels are used to cut the metal outer layer and the polyetheretherketone inner layer respectively, the cutting of the two does not interfere with each other, and the polyetheretherketone is not easy to stick to the cutting wheel.
