[0001] The utility model relates to the technical field of wire stripping, in particular to a front-section cutting and stripping mechanism. Background Art:

[0002] A terminal wire includes an electric wire and a terminal fixed to the end of the electric wire. Before assembly, a stripping mechanism is needed to strip the end face of the electric wire to expose the metal wire core at the end of the electric wire. Then, a terminal is pressed and fixed to the metal wire core of the electric wire through a terminal pressing machine to complete the production of the terminal wire.

[0003] The Chinese patent application for invention with the publication number of CN118367487A discloses a wiring cable end stripping device, which includes: a base; a lower cutting member slidably arranged on the base in the front-back direction, the lower cutting member includes a first lower skin cutting knife, a lower cutting knife and a second lower skin cutting knife arranged at intervals in the front-back direction in sequence; an upper cutting member arranged above the lower cutting member, slidably connected with the lower cutting member and slidable in the vertical direction, the upper cutting member includes a first upper skin cutting knife, an upper cutting knife and a second upper skin cutting knife arranged at intervals in the front-back direction in sequence, a pressing block is arranged on the upper part of the upper cutting member, and the pressing block is provided with an inclined sliding surface; a lower pressing block, the bottom of which is slidably connected with the sliding surface; a restraining sleeve fixedly arranged and sleeved at the connection part of the lower pressing block and the pressing block; and a driving mechanism connected with the lower pressing block to drive the lower pressing block to move downward. First, the lower pressing block and the pressing block move downward in the restraining sleeve, the upper cutting knife and the lower cutting knife cut the cable to generate two ends, the first upper skin cutting knife and the first lower skin cutting knife cut the outer skin of one of the ends located in the front, and the second upper skin cutting knife and the second lower skin cutting knife cut the outer skin of one of the ends located in the back; then, the pressing block leaves the restraining sleeve and slides relative to the lower pressing block, driving the upper cutting member and the lower cutting member to move forward to remove the outer skin of one of the ends located in the back.

[0004] Although the above wiring cable end stripping device can strip the cable to remove the cable outer skin, there are some deficiencies in the above wiring cable end stripping device: the above wiring cable end stripping device uses a driving mechanism to drive the lower pressing block and the pressing block to move downward in the restraining sleeve, so that the first and second skin cutting knives move respectively towards the first and second lower skin cutting knives to approach the first and second lower skin cutting knives relatively, thereby realizing the skin cutting action. However, in this process, the first and second lower skin cutting knives do not move, only the first and second upper skin cutting knives move downward, which results in a large movement stroke of the first and second upper skin cutting knives and affects the skin cutting quality. In addition, the driving mechanism is a cylinder, and its operating precision is not high, and it cannot accurately control the stroke precision of the first and second upper skin cutting knives moving downward.

[0022] The present utility model will be further described below in conjunction with specific embodiments and the accompanying drawings.

[0023] See Figures 1-4As shown in the figure, there is a front-end cutting and peeling mechanism, which includes a sliding seat 1, a first rack cutter holder 2 and a second rack cutter holder 3 that are arranged side by side and are vertically slidably inserted into the sliding seat 1, a linkage gear 4 installed in the sliding seat 1 and used to drive the first rack cutter holder 2 and the second rack cutter holder 3 to slide synchronously in opposite directions, a connecting rod assembly 5 connected to the lower end of the first rack cutter holder 2 or the second rack cutter holder 3, a cutting upper blade 61 and a cutting lower blade 62 that are respectively installed on the first and second rack cutter holders and are vertically corresponding, and a peeling upper blade 63 and a peeling lower blade 64 that are respectively installed on the first and second rack cutter holders and are vertically corresponding. A rubber stripping push piece 71 for removing the rubber generated after the wire is cut and peeled is also provided on the first rack cutter holder 2, and a rubber stripping air cylinder 72 for driving the rubber stripping push piece 71 to move up and down. In this embodiment, the connecting rod assembly 5 is connected to the lower end of the first rack cutter holder 2. When the present invention is working, the camshaft drives the connecting rod assembly 5 to move downward, and then pulls the first rack cutter holder 2 to move downward. At this time, when the first rack cutter holder 2 moves downward, it drives the linkage gear 4 to rotate counterclockwise, and then drives the second rack cutter holder 3 to move upward, so as to drive the first rack cutter holder 2 and the second rack cutter holder 3 to slide synchronously in opposite directions. At this time, the first rack cutter holder 2 and the second rack cutter holder 3 approach each other, and the cutting upper blade 61 and the cutting lower blade 62 close to each other to cut the front end of the wire. At the same time, the peeling upper blade 63 and the peeling lower blade 64 close to each other to cut the rubber of the wire. Then, the camshaft drives the connecting rod assembly 5 to move upward, and then pushes the first rack cutter holder 2 to move upward. At this time, when the first rack cutter holder 2 moves upward, it drives the linkage gear 4 to rotate clockwise, and then drives the second rack cutter holder 3 to move downward, so as to drive the first rack cutter holder 2 and the second rack cutter holder 3 to slide synchronously in opposite directions. At this time, the first rack cutter holder 2 and the second rack cutter holder 3 expand, that is, the cutting upper blade 61 and the cutting lower blade 62 open, and the peeling upper blade 63 and the peeling lower blade 64 open. At this time, the rubber stripping air cylinder 72 pushes the rubber stripping push piece 71 to move downward, and the rubber stripping push piece 71 pushes the cut rubber on the wire and removes the rubber relative to the metal wire core of the wire, and then resets, thus completing the cutting and peeling action of the wire. That is to say, the present invention uses the connecting rod assembly 5 to drive the first rack cutter holder 2 and the second rack cutter holder 3 to slide synchronously in opposite directions, and then drives the cutting upper blade 61 and the cutting lower blade 62 to close or open each other, and the peeling upper blade 63 and the peeling lower blade 64 close or open synchronously. Its operation is stable, and the operation accuracy is high, and it can make the stroke of each blade the same, so as to ensure the quality of wire cutting and peeling. And the present invention uses the rubber stripping air cylinder 72 to cooperate with the rubber stripping push piece 71 to remove the cut rubber on the wire relative to the metal wire core to complete the peeling action. Its structure is simple, and the peeling stability is high.

[0024] The upper ends of the first rack tool rest 2 and the second rack tool rest 3 both extend out of the upper end of the sliding seat 1 and are distributed at intervals in the upper and lower layers. A stroke limit screw 8 is spirally arranged at the upper end of any one of the first rack tool rest 2 and the second rack tool rest 3 to adjust the relative position to prevent the upper ends of the first rack tool rest 2 and the second rack tool rest 3 from approaching too closely. In the actual application process, although the link assembly 5 drives the first rack tool rest 2 and the second rack tool rest 3 to slide synchronously in opposite directions, the strokes of the first rack tool rest 2 and the second rack tool rest 3 can be controlled. However, after the cutting upper blade 61 and the cutting lower blade 62, and the peeling upper blade 63 and the peeling lower blade 64 are installed, errors will be formed. It is necessary to adjust the spacing between the cutting upper blade 61 and the cutting lower blade 62, and the spacing between the peeling upper blade 63 and the peeling lower blade 64. At this time, if the link assembly 5 drives the first rack tool rest 2 and the second rack tool rest 3 to approach each other, since the spacing between the cutting upper blade 61 and the cutting lower blade 62, and the spacing between the peeling upper blade 63 and the peeling lower blade 64 are both too small, the phenomenon of the blades colliding with each other may occur. At this time, the minimum distance at which the first rack tool rest 2 and the second rack tool rest 3 approach each other is adjusted through the stroke limit screw 8, so as to ensure that the phenomenon of the blades colliding with each other will not occur, and then it is convenient to adjust the spacing between the cutting upper blade 61 and the cutting lower blade 62, and the spacing between the peeling upper blade 63 and the peeling lower blade 64 in the later stage. Or, due to a fault, the first rack tool rest 2 and the second rack tool rest 3 may approach each other relatively excessively. Due to the existence of the stroke limit screw 8, the phenomenon that the first rack tool rest 2 and the second rack tool rest 3 approach each other relatively excessively can be effectively prevented, so as to achieve a protective effect.

[0025] The assembly structure of the first rack tool rest 2, the second rack tool rest 3 and the sliding seat 1 is as follows:

[0026] The lower ends of the first rack tool rest 2 and the second rack tool rest 3 penetrate through the first sliding hole 11 and the second sliding hole 12 of the sliding seat 1 from top to bottom. A plurality of convex strips 10 are formed at intervals in the vertical direction in both the first sliding hole 11 and the second sliding hole 12. The surface of the convex strip 10 is in contact with the outer surface of the first rack tool rest 2 or the second rack tool rest 3, so as to reduce the contact area and further reduce wear. This can not only improve the stability and smoothness of the up and down sliding of the first rack tool rest 2 and the second rack tool rest 3, but also achieve the purpose of protection and improve the service life.

[0027] The first sliding hole 11 and the second sliding hole 12 are both opened along the front end face of the sliding seat 1 and penetrate through the upper and lower end faces of the sliding seat 1. Moreover, first retaining pieces 13 and second retaining pieces 14 for preventing the lower ends of the first rack tool rest 2 and the second rack tool rest 3 from slipping out of the first sliding hole 11 and the second sliding hole 12 are arranged on both the upper and lower sides of the front end face of the sliding seat 1. Its assembly structure is simple, and enables the first rack tool rest 2 and the second rack tool rest 3 to be side-mounted, and its installation is simpler, more convenient, and highly efficient. The sliding seat 1 is further provided with a protective cover 15, and the protective cover 15 covers the first retaining piece 13, the second retaining piece 14, the first sliding hole 11, the second sliding hole 12, and the linkage gear 4, thereby being able to prevent foreign objects from entering and achieving a good protective effect.

[0028] The first rack tool rest 2 includes a toothed first sliding rod 21 and a first tool bar 22 installed at the upper end of the first sliding rod 21 and distributed horizontally. Among them, a first positioning groove 211 is arranged at the upper end of the first sliding rod 21, and one end of the first tool bar 22 is inlaid and installed in the first positioning groove 211 for positioning and is locked by a second screw 212. Its structure is simple and stable; the structure of the second rack tool rest 3 is the same as that of the first rack tool rest 2, and will not be elaborated here one by one.

[0029] An installation position 16 communicating the first sliding hole 11 and the second sliding hole 12 is arranged on the front end face of the sliding seat 1. The middle part of the linkage gear 4 has a through hole 41. First bearings 42 and second bearings 43 with flanges are respectively inlaid at both port ends of the through hole 41. A first screw 44 passes through the first bearing 42 and the second bearing 43 and is helically fixed to the sliding seat 1. Moreover, the first bearing 42 and the second bearing 43 clamp and position the middle part of the linkage gear 4 through the flanges on their outer edges. Compared with inlaying a single bearing without a flange, the first bearings 42 and second bearings 43 with flanges have low assembly requirements, extremely high assembly efficiency, and can form a stable assembly effect.

[0030] A first gap for the rubber stripping push piece 71 to pass through is formed between the cutting upper blade 61 and the rubber stripping upper blade 63. A first gap for the rubber stripping push piece 71 and the rubber to pass through is formed between the rubber stripping lower blade 64 and the cutting lower blade 62. An adsorption hole seat 9 for collecting the rubber is further arranged at the lower ends of the rubber stripping lower blade 64 and the cutting lower blade 62. The adsorption hole seat 9 is communicated with a negative pressure device through a pipeline. After the rubber is stripped off, the adsorption hole seat 9 sucks away the rubber, avoiding the phenomenon that the rubber formed after stripping is messy and cannot ensure cleanliness, and further enabling the present utility model to have an automatic cleaning function.

[0031] A guide seat 73 is provided on the first rack tool rest 2. The guide seat 73 is located above the cutting upper blade 61 and the peeling upper blade 63. The guide seat 73 is provided with a guide hole 731 corresponding to the first interval. The rubber stripping push piece 71 passes through the guide hole 731, thus ensuring that the rubber stripping push piece 71 runs more stably. The rubber stripping cylinder 72 is fixed to the upper end of the guide seat 73.

[0032] Among them, the rubber stripping push piece 71 is a manganese steel sheet.

[0033] The sliding seat 1 is installed on the vertical frame 100 in a manner that its vertical position can be adjusted. By adjusting the height of the sliding seat 1 relative to the vertical frame 100, the height of the entire mechanism can be adjusted to meet the usage requirements. The connecting rod assembly 5 is connected to the camshaft motor module.

[0034] In summary, the utility model uses the connecting rod assembly 5 to drive the first rack tool rest 2 and the second rack tool rest 3 to slide synchronously in opposite directions, thereby driving the cutting upper blade 61 and the cutting lower blade 62 to close or open each other, and the peeling upper blade 63 and the peeling lower blade 64 to close or open each other synchronously. Its operation is stable, with high operation accuracy, and can make the strokes of each blade the same, thus ensuring the quality of wire cutting and peeling. Moreover, the utility model uses the rubber stripping cylinder 72 in cooperation with the rubber stripping push piece 71 to push the cut rubber on the wire away from the metal wire core to complete the peeling action, with a simple structure and high peeling stability.

[0035] Certainly, the above are only specific embodiments of the utility model, and are not intended to limit the scope of implementation of the utility model. Any equivalent changes or modifications made according to the structure, characteristics, and principles described in the scope of the patent application of the utility model should be included in the scope of the patent application of the utility model.
