Description

Technical Field

[0001] The present invention relates to the technical field of cutting processing, and particularly relates to a PTFE rod cutting processing machine tool with a chip suction function. Background Art

[0002] PTFE (polytetrafluoroethylene) rod is a high-molecular material mainly composed of polytetrafluoroethylene, which has excellent chemical stability, corrosion resistance, high temperature resistance and low friction coefficient. PTFE rods usually need to be formed into required parts or components through cutting processing. Although PTFE is a high-performance material, its forming method is limited by its physical and chemical properties, and cutting processing is the key step to achieve high precision and complex shapes.

[0003] A large amount of chips will be generated during the chip cutting process of the rod. Some chips are relatively long, and the chips will splash to various positions on the operating table during the cutting process. Ordinary cutting processing machine tools usually adopt a chip blowing device. However, when using the chip blowing process, the flying chips are likely to pollute the processing environment, and the chip materials are not easy to recycle. In addition, some cutting processing machine tools will set a chip suction device at the middle position of the operating table, which can adsorb the chips falling on the operating table. However, the coverage range of the chip suction device is relatively limited, and it can only effectively adsorb a part of the area in the middle of the operating table, and the chips far away from the middle position cannot be effectively adsorbed. In addition, the too long length of the chips will also affect the adsorption effect of the chip suction device on them, and there is a risk of blocking the air suction pipe of the chip suction structure, affecting the chip suction efficiency. Summary of the Invention

[0043] The following combines Figures 1 - 11 to describe a PTFE bar cutting and processing machine with a chip suction function of the present invention.

[0044] As Figures 1 - 8 shown, in one embodiment, a PTFE bar cutting and processing machine with a chip suction function includes a frame 1 and a cutting frame 2 movably mounted on the frame 1, and further includes a fixture 3, a moving frame 4, a moving rod 10, a movable plate 6, a vertical plate 7, a push plate 5, a transmission component 8 and a cutting component 9.

[0045] Among them, a horizontal groove 41 is formed at the bottom of the moving frame 4, a vertical plate 7 is movably arranged in the horizontal groove 41, a movable plate 6 is movably arranged in the moving frame 4, the movable plate 6 is fixedly connected with the vertical plate 7, a moving rod 10 is fixedly installed on one side of the moving frame 4, one end of which movably penetrates through the fixture 3, a push plate 5 is movably installed at the bottom of the vertical plate 7, a transmission assembly 8 is arranged on one side of the moving frame 4 and can drive the push plate 5 to move, and a cutting assembly 9 can shear the chips during the movement of the push plate 5.

[0046] Specifically, the bar stock to be processed is positioned by the fixture 3, and then the cutting frame 2 is moved downward along the machine frame 1. The cutting head on the cutting frame 2 can cut the bar stock. A chip blowing device can be arranged at the position of the cutting head, which can effectively prevent the chips generated during the cutting process from being too long and winding around the cutting head, affecting the processing. A chip suction structure can be arranged at the lower position of the fixture 3, which can adsorb the chips generated during the cutting process and ensure the cleanliness of the machine frame 1. During the processing, the transmission assembly 8 can drive the moving frame 4, the movable plate 6, the vertical plate 7 and the push plate 5 to move together towards the middle. During the movement of the push plate 5, the chips at the edge can be pushed towards the middle position, which is convenient for the chip suction structure to adsorb them. During the movement of the moving frame 4, the moving rod 10 will be driven to move along the fixture 3, which can ensure the stability of the moving frame 4 during the movement. Secondly, during the movement of the push plate 5, the cutting assembly 9 can also shear the chips accumulated on one side of the push plate 5, shorten the length of the chips, which is convenient for the chip suction structure to adsorb them and avoid blocking the chip suction structure.

[0047] Refer to Figures 6 - 8 As shown, in this embodiment, the cutting assembly 9 includes a serrated plate 91 fixedly installed on one side of the push plate 5. A notch 51 is formed at the bottom of the push plate 5 where the serrated wave is located. A cutting plate 92 is movably arranged in the notch 51. The inside of the push plate 5 is hollow, and the other end of the cutting plate 92 is located inside the push plate 5.

[0048] Specifically, during the movement of the push plate 5, the chips along the way will be pushed towards the middle position of the machine frame 1 together. The chips will accumulate on one side of the push plate 5. Some chips are located between adjacent serrations of the serrated plate 91. During the movement of the push plate 5, the cutting plate 92 is reciprocated horizontally along the notch 51. During the movement of the cutting plate 92, the chips in the serrated plate 91 will be cut, reducing their length, which is convenient for the chip suction structure to adsorb them.

[0049] Refer to Figure 8 As shown, in this embodiment, the part of the cutting plate 92 located inside the push plate 5 is movably connected with a horizontal plate 93. One end of the horizontal plate 93 is movably connected with a triangular plate 94. One side of the triangular plate 94 is movably connected with a rotating plate 95. The end of the rotating plate 95 far from the triangular plate 94 is fixedly provided with a rotating shaft 96. The rotating shaft 96 is rotatably connected with the inner wall of the push plate 5. A swinging plate 97 is movably arranged on the triangular plate 94. The other end of the swinging plate 97 is rotatably connected with the inner wall of the push plate 5.

[0050] Specifically, during the movement of the push plate 5, the rotating shaft 96 is rotated. The rotation of the rotating shaft 96 drives the rotating plate 95 to rotate, thereby driving the triangular plate 94 to shake, driving the cross plate 93 and the cutting plate 92 to move horizontally back and forth. The movement of the cutting plate 92 cuts the chips. While the triangular plate 94 is shaking, it drives the swing plate 97 to swing left and right, and the swing plate 97 can provide balance for the shaking of the triangular plate 94.

[0051] Refer to Figure 2 As shown, in this embodiment, the transmission assembly 8 includes a driving gear 81. An elliptical groove 61 is formed in the movable plate 6, and a plurality of internal teeth 82 are arranged in an array in the elliptical groove 61. The driving gear 81 is in transmission connection with the internal teeth 82. A rotating rod 83 is fixedly arranged through the center of the driving gear 81, and one end of the rotating rod 83 away from the driving gear 81 is rotationally connected to the fixture 3.

[0052] Specifically, during the processing, the rotating rod 83 is rotated counterclockwise. The counterclockwise rotation of the rotating rod 83 drives the driving gear 81 to rotate counterclockwise. The counterclockwise rotation of the driving gear 81 drives the movable plate 6 and the moving frame 4 to move through meshing with the internal teeth 82. In the initial state, the driving gear 81 is located above the elliptical groove 61 and meshes with the upper internal tooth 82 section. The movable plate 6 is located at a lower position inside the moving frame 4. At this time, the push plate 5 is in contact with the surface of the frame 1. When the driving gear 81 is rotated counterclockwise, the rotation of the driving gear 81 drives the movable plate 6 and the moving frame 4 to move horizontally. At this time, during the movement of the push plate 5, the chips can be pushed towards the middle position. When the movable plate 6 moves to the arc position of the elliptical groove 61, if the driving gear 81 continues to rotate in the same direction, it will drive the movable plate 6 to move upward along the moving frame 4, and the vertical plate 7 and the push plate 5 will also move upward correspondingly. The vertical plate 7 moves upward relative to the horizontal groove 41. Subsequently, when the driving gear 81 continues to rotate, the driving gear 81 meshes with the internal teeth 82 of the lower straight section of the elliptical groove 61, driving the movable plate 6, the moving frame 4, the vertical plate 7, and the push plate 5 to move in the reverse direction. The push plate 5 will not be in contact with the surface of the frame 1 during the return journey, which can prevent the chips in the middle position from being pushed back to the edge position during the return journey. When the movable plate 6 moves to the other arc of the elliptical groove 61 and meshes with the driving gear 81, under the drive of the driving gear 81, the movable plate 6 will move downward to the initial position. At this time, the moving frame 4 also returns to the initial position, and the push plate 5 will be in contact with the surface of the frame 1 again, facilitating the next push of the chips.

[0053] Refer to Figure 2 and Figure 3 As shown, in this embodiment, a limiting rod 11 is fixedly arranged at the bottom of the movable plate 6. The limiting rod 11 is slidably connected to the horizontal groove 41. An elliptical plate 12 is fixedly arranged below the moving frame 4 on the frame 1, and one end of the limiting rod 11 away from the movable plate 6 is movably abutted against the surface of the elliptical plate 12.

[0054] Specifically, when the moving frame 4 and the movable plate 6 move towards the middle, the end of the limiting rod 11 away from the movable plate 6 will slide along the bottom of the elliptical plate 12, and the pushing plate 5 will slide along the surface of the frame 1 to push the chips. After moving a certain distance, the movable plate 6 will move upward. At this time, the limiting rod 11 moves to the end of the elliptical plate 12, and the limiting rod 11 moves upward along the elliptical plate 12, and the pushing plate 5 also moves upward and no longer contacts the surface of the frame 1. Subsequently, the movable plate 6 and the moving frame 4 move together in the reverse direction to the initial position. During this process, the limiting rod 11 slides along the top of the elliptical plate 12, and the movable plate 6 will move while maintaining this state. The pushing plate 5 will not fit against the surface of the frame 1 during the return process. The change in the contact position between the limiting rod 11 and the elliptical plate 12 can adjust the height of the pushing plate 5.

[0055] Refer to Figure 1 、 Figure 6 and Figure 8 As shown in

[0056]

[0057] Figure 5 Refer to As shown in

[0058] Specifically, when the pushing plate 5 moves horizontally towards the middle, the rotating gear 14 will mesh with the driving rack 15, and the driving gear 81 will rotate to drive the cross bar 13 to rotate. The rotation of the cross bar 13 drives the rotating shaft 96 to rotate through the transmission of bevel gears. The rotation of the rotating shaft 96 will ultimately achieve the horizontal reciprocating movement of the cutting plate 92, and can cut the chips in the sawtooth plate 91. When the pushing plate 5 moves upward and then moves in the reverse direction while maintaining this state, the rotating gear 14 will not mesh with the driving rack 15.

[0059] Figure 5 Refer to Figure 5As shown, in this embodiment, a moving gear 18 is fixedly sleeved outside one of the rotating cylinders 16, and a positioning rack 19 is fixedly arranged in the transverse groove 41. The moving gear 18 is in meshing transmission with the positioning rack 19.

[0060] Specifically, during the upward movement of the vertical plate 7 along the transverse groove 41, the moving gear 18 will mesh with the positioning rack 19, and the moving gear 18 will rotate, thereby driving the rotation of the rotating cylinder 16, the connecting plate 17 and the pushing plate 5, so that the chips will fall off.

[0061] Refer to Figure 5 and Figure 9 As shown, in this embodiment, a moving plate 20 is movably arranged in the connecting plate 17, and the bottom of the moving plate 20 is fixedly connected to the top of the pushing plate 5.

[0062] Specifically, during the upward movement and flipping of the connecting plate 17 and the pushing plate 5, the moving plate 20 reciprocates horizontally along the connecting plate 17. The movement of the moving plate 20 will drive the pushing plate 5 to reciprocate horizontally, so that the chips can fall off further.

[0063] Refer to Figures 9 - 11 As shown, in this embodiment, a positioning rod 21 is fixedly arranged at one end of the moving plate 20 away from the pushing plate 5. A fixing rod 22 is movably penetrated through the rotating cylinder 16. Both ends of the fixing rod 22 are fixedly connected to the inner wall of the groove 71. A ring 23 is fixedly sleeved outside the fixing rod 22. A plurality of protrusions 24 are arranged on the ring 23. An annular groove 231 is opened in the ring 23. One end of the positioning rod 21 away from the moving plate 20 is slidably embedded in the annular groove 231.

[0064] Specifically, during the rotation of the connecting plate 17, the fixing rod 22 remains stationary, and the positioning rod 21 will slide along the annular groove 231 opened in the ring 23. Since a plurality of protrusions 24 are arranged on the ring 23, during the sliding of the positioning rod 21, it will reciprocate horizontally relative to the connecting plate 17. The movement of the positioning rod 21 will also drive the moving plate 20 and the pushing plate 5 to reciprocate, and can further shake off the chips.

[0065] The technical features of the above-described embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope described in this specification.

[0066] The above-described embodiments merely represent several implementation manners of the present invention. The description thereof is relatively specific and detailed, but it should not be construed as a limitation to the scope of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several modifications and improvements can still be made, and these all fall within the protection scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the appended claims.
