Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts fall within the scope of protection of the present invention.

[0028] Embodiment 1

[0029] As Figures 1 to 6 shown, this embodiment proposes a fork twisting machine for cable production, including a bottom plate 1. One side of the upper end surface of the bottom plate 1 is fixedly installed with a vertical plate 2. One side of the top of the vertical plate 2 is fixedly installed with a support frame 3. A clamping and conveying assembly 100 is installed on the vertical plate 2. One side of the vertical plate 2 is fixedly installed with a first L-shaped support plate 4. A wire passing hole is opened on one side of the first L-shaped support plate 4. A cutting assembly 200 is installed on the first L-shaped support plate 4;

[0030] The clamping and conveying assembly 100 includes a drive motor 101 fixedly installed on one side of the bottom of the support frame 3. The input end of the drive motor 101 is connected to a power source through an external cable. The output end of the drive motor 101 passes through the support frame 3 through a bearing and is fixedly installed with a connecting rod 102. The end of the connecting rod 102 away from the drive motor 101 is rotatably connected to the inner top wall of the support frame 3. The outer surface of the bottom of the connecting rod 102 is fixedly installed with a first driving bevel gear 103. The outer surface of the top of the connecting rod 102 is slidably connected with a sleeve rod 104. The bottom outer surface of the sleeve rod 104 is fixedly connected with a second driving bevel gear 105. The inner wall of the sleeve rod 104 is symmetrically provided with grooves 106. The outer surface of the connecting rod 102 is symmetrically fixedly installed with ribs 107. The ribs 107 are matched with the grooves 106. The sliding block 109 is matched with the sliding groove 110;

[0031] On one side of the top of the rod set 104, a support frame 108 is fixedly installed. On one side of the support frame 108, a sliding block 109 is fixedly installed. On one side of the top of the vertical plate 2, a sliding groove 110 is opened. A first spring 111 is fixedly installed between the bottom end of the sliding block 109 and the bottom wall of the sliding groove 110. The top end of the sliding block 109 is rotatably connected to a threaded rod 112. The top end of the threaded rod 112 is threadedly penetrated through the top of the vertical plate 2 and fixedly installed with a rotating handle 113. On one side of the vertical plate 2, an L-shaped support plate two 114 is fixedly installed. On the support frame 108, an upper pressing roller 115 is rotatably connected. On the outer surface between the lower pressing roller 116 and the upper pressing roller 115, a wire laying groove 5 is opened. On one side of the vertical plate 2, a lower pressing roller 116 is rotatably connected. The upper pressing roller 115 is located directly above the lower pressing roller 116. One ends of the upper pressing roller 115 and the lower pressing roller 116 both pass through one side of the support frame 108 and one side of the L-shaped support plate two 114 through bearings and are fixedly installed with driven bevel gears 117. The driving bevel gear one 103 and the driving bevel gear two 105 are respectively meshed with the corresponding driven bevel gears 117;

[0032] By setting the clamping and conveying assembly 100, it can effectively prevent the cable from loosening while being cut. When it is necessary to prevent the cable from loosening while being cut, by rotating the rotating handle 113, the sliding block 109 at the bottom of the threaded rod 112 is driven to move downward, thereby driving the support frame 108 on one side of the sliding block 109 to move downward. Through the mutual cooperation of the groove 106 and the rib 107, the upper pressing roller 115, the driven bevel gear 117 and the driving bevel gear two 105 are driven to move downward simultaneously, thereby driving the upper pressing roller 115 to extrude and fix the stranded cable. By starting the driving motor 101 to drive the driving bevel gear one 103 and the driving bevel gear two 105 on the connecting rod 102 to rotate simultaneously, the upper pressing roller 115 and the lower pressing roller 116 are driven to rotate relatively, thereby clamping and conveying the cable. When the cable is cut, the upper pressing roller 115 and the lower pressing roller 116 will always clamp the cable, thereby effectively preventing the cable from loosening while being cut.

[0033] Embodiment 2

[0034] As Figures 1 to 6As shown in the figure, based on the same concept as in the above-mentioned Embodiment 1, this embodiment also proposes that the cutting assembly 200 includes a connecting plate 201 fixedly installed on one side of the L-shaped support plate 4. A hydraulic cylinder 202 is fixedly installed on the top of the connecting plate 201. A lower cutting tool head 203 is fixedly installed on one side of the bottom of the L-shaped support plate 4. An upper cutting tool head 204 is arranged directly above the lower cutting tool head 203. The upper cutting tool head 204 and the lower cutting tool head 203 always remain in a separated state. Two fixing plates 205 are symmetrically and fixedly installed on one side of the L-shaped support plate 4. Two extension plates 206 are fixedly installed on the symmetrically two sides of the top of the upper cutting tool head 204. A second spring 207 is fixedly installed between the extension plate 206 and the fixing plate 205. The output end of the hydraulic cylinder 202 is fixedly installed with a pressing plate 208. The pressing plate 208 is directly below and directly above the upper cutting tool head 204. A T-shaped slider 209 is fixedly installed on one side of the upper cutting tool head 204. A T-shaped sliding groove 210 matching the T-shaped slider 209 is formed on one side of the L-shaped support plate 4. Through the provided cutting assembly 200, the cable can be quickly cut. When it is necessary to quickly cut the cable, the hydraulic cylinder 202 is started to drive the pressing plate 208 to move downward quickly towards the upper cutting tool head 204. When the upper cutting tool head 204 abuts against the lower cutting tool head 203, the cable is quickly cut. When the hydraulic cylinder 202 drives the pressing plate 208 to move upward, the upper cutting tool head 204 is separated from the lower cutting tool head 203 by the elastic action of the second spring 207, so as to quickly cut the cable.

[0035] During operation, first, the stranded cable is passed through between the upper pressing roller 115 and the lower pressing roller 116, then through the wire passing hole. Then, by rotating the rotating handle 113, the sliding block 109 at the bottom of the threaded rod 112 is driven to move downward, thereby driving the support frame 108 on one side of the sliding block 109 to move downward. Through the mutual cooperation of the groove 106 and the rib 107, the upper pressing roller 115, the driven bevel gear 117 and the driving bevel gear two 105 are simultaneously driven to move downward, so as to drive the upper pressing roller 115 to extrude and fix the stranded cable. Then, by starting the driving motor 101, the driving bevel gear one 103 and the driving bevel gear two 105 on the connecting rod 102 are simultaneously rotated, so as to drive the upper pressing roller 115 and the lower pressing roller 116 to rotate relatively, so as to clamp and convey the cable. When it is necessary to cut the cable, the hydraulic cylinder 202 is started to drive the pressing plate 208 to move downward quickly towards the upper cutting tool head 204. When the upper cutting tool head 204 abuts against the lower cutting tool head 203, the cable is quickly cut. When the hydraulic cylinder 202 drives the pressing plate 208 to move upward, the upper cutting tool head 204 is separated from the lower cutting tool head 203 by the elastic action of the second spring 207. Since the upper pressing roller 115 and the lower pressing roller 116 always clamp the cable, the cable is prevented from loosening while being cut.

[0036] The above are only the preferred embodiments of the present utility model, and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
