[0020] (2) In this solution, the guide punch plate is fixed on the slide plate and a corresponding guide rail is set on the fixed base. The slide plate is then slidably fixed on the guide rail. The slide plate drives the guide punch plate to move. The direction of the guide rail is perpendicular to the direction of the ribbon cable slot. That is, the direction of the slide plate and the direction of the ribbon cable are perpendicular to each other. When the ribbon cable is placed in the ribbon cable slot, the guide punch plate can be moved out from under the punching knife, which is convenient for the ribbon cable to be placed and away from the punching knife, thus improving the safety of the ribbon cable placement. The operation is convenient and the movement is easy. Attached Figure Description

[0034] Example 1

[0035] like Figure 1 and Figure 4 As shown, this embodiment provides a pneumatic cable punching device, including a fixed base 1, a guide punching plate 2, a punching cylinder 3 and a punching knife 4. The guide punching plate 2 is movably fixed on the fixed base 1, the punching cylinder 3 is fixed on the fixed base, and the punching cylinder 3 drives the punching knife 4.

[0036] The guide punch plate 2 is provided with a cable slot 21, which matches the shape of the cable. The bottom of the cable slot 21 is provided with a cable punch 22, which is located below the stamping knife 4 and directly opposite the stamping knife 4. The cutting head of the stamping knife 4 matches the shape of the cable punch 22. A positioning block 5 is fixed on the guide punch plate 2. The positioning block 5 is located on the cable punch 22. The positioning block 5 is provided with a cutting head guide hole 51, which is coaxially arranged with the cable punch 22. The side of the positioning block 5 closest to the cable slot 21 is provided with a cable positioning groove.

[0037] Working principle: The ribbon cable is placed in the ribbon cable slot 21, and the ribbon cable is pushed along the ribbon cable slot 21 to the ribbon cable positioning groove set at the lower end of the positioning block 5. When the ribbon cable moves to the position of the ribbon cable punch 22, it is limited by the ribbon cable positioning groove. Then, the stamping cylinder 3 drives the stamping knife 4 to move downward. The stamping knife 4 passes through the knife head guide hole 51 on the positioning block 5 and breaks the connecting rib of the ribbon cable on the ribbon cable punch 22, thus completing the breaking of the ribbon cable.

[0038] The guide punch plate 2 temporarily fixes and guides the ribbon cable, which moves along the ribbon cable slot 21. The ribbon cable positioning groove at the lower end of the positioning block 5 limits the movement of the ribbon cable, ensuring that the processing position of the ribbon cable is in the preset position and between the cutter head guide hole 51 and the ribbon cable punch hole 22. This positioning of the ribbon cable is highly accurate and precise. The punching knife 4 passes through the cutter head guide hole 51 to punch the ribbon cable. The operation is simple and efficient, improving the accuracy and processing efficiency of ribbon cable punching and effectively increasing the yield of ribbon cable punching.

[0039] Preferred implementation methods, such as Figures 1 to 4 As shown, the fixed base 1 is provided with a guide rail 11, a slide plate 12 and a limiting block 13. The guide rail 11 is fixed on the fixed base 1, the guide perforated plate 2 is fixed on the slide plate 12, the slide plate 12 is movably connected to the guide rail 11, and the limiting block 13 is fixed on the fixed base 1 and located on the movement trajectory of the slide plate 12.

[0040] The guide rail 11 has a T-shaped cross-section, and the fixed base 1 has a groove that mates with the guide rail 11, through which the guide rail 11 passes. The direction of the guide rail 11 is perpendicular to the direction of the cable tray 21.

[0041] The guide perforated plate is fixed on the slide plate, and a corresponding guide rail is set on the fixed base. The slide plate is then slidably fixed on the guide rail. The slide plate drives the guide perforated plate to move. The direction of the guide rail is perpendicular to the direction of the cable slot. That is, the direction of movement of the slide plate is perpendicular to the direction of movement of the cable. When the cable is placed in the cable slot, the guide perforated plate can be moved out from under the punching knife, which is convenient for placing the cable and away from the punching knife, thus improving the safety of cable placement. The limit block 13 is used to limit the working position of the slide plate 12, making operation convenient and movement easy.

[0042] Optionally, in this embodiment, a pad 6 is provided between the slide plate 12 and the guide punch plate 2. The pad 6 is provided with a punching receiving hole, which is located below the cable punch 22. A receiving drawer 61 is provided inside the punching receiving hole, and the receiving drawer 61 is movably fixed inside the punching receiving hole.

[0043] By setting a punching hole below the cable punching hole 22, a receiving drawer 61 is installed to directly store the broken pieces of the cable. When a certain amount is accumulated, the receiving drawer 61 is removed using the handle on it to empty the broken pieces inside, thus preventing them from scattering and affecting subsequent processing steps and ensuring the continuity of processing.

[0044] Preferred implementation methods, such as Figure 5 As shown, limiting plates 23 are also provided on both sides of the cable slot 21. The limiting plates 23 are located at the end of the cable slot 21 away from the cable punch 22, and the limiting plates 23 are arranged in parallel. The upper end of the limiting plate 23 has an arc-shaped structure.

[0045] By setting the limit plate 23 away from the cable slot 21, the cable placed in the cable slot 21 is temporarily clamped to ensure the stability of subsequent cable pushing. Moreover, an arc-shaped structure is set at the upper end of the limit plate 23 to facilitate the placement of the cable into the cable slot 21 between the limit plates 23, thereby improving the cable placement efficiency.

[0046] Specifically, a cylinder base 8 is fixed on the fixed base 1. The cylinder base 8 has an L-shaped structure and reinforcing ribs on both sides. The stamping cylinder 3 is fixed on the side of the cylinder base 8 away from the fixed base 1.

[0047] Among them, such as Figure 6 As shown, a stamping guide block 7 is provided between the stamping cylinder 3 and the stamping cutter 4. The upper end of the stamping guide block 7 is connected to the stamping cylinder 3, and the lower end of the stamping guide block 7 is connected to the stamping cutter 4. A guide rod 81 is provided on the cylinder base 8, and the guide rod 81 passes through the stamping guide block 7. The stamping guide block 7 is movably connected to the guide rod 81. The stamping cutter 4 is detachably fixed to the end of the stamping guide block 7 away from the stamping cylinder 3 by bolts.

[0048] By setting a stamping guide block 7 between the stamping cylinder 3 and the stamping cutter 4, and using a guide rod 81 to guide the movement path of the stamping guide block 7, the accuracy and stability of the movement path of the stamping cutter 4 on the stamping guide block 7 are ensured, thereby improving the accuracy of the stamping cutter 4 in cutting the cable.

[0049] More specifically, the ribbon cable to be punched is placed in the guide plate slot, pushed in to the ribbon cable punching position on the guide punching plate, and the slide plate is pushed forward to the limit block. The stamping cylinder is activated, and the stamping cylinder moves downward. The stamping guide block moves downward under the force of the stamping cylinder. The stamping cutter is connected to the stamping guide block and moves downward at the same time, passing through the cutter guide hole on the positioning block, and then through the ribbon cable punching hole on the guide punching plate to break the rib connected to the ribbon cable. The structure is simple, the positioning is accurate, the ribbon cable breaking efficiency is high, and the breaking yield can be guaranteed, reducing the situation of product defects caused by inaccurate breaking position, and effectively reducing costs.

[0050] The preferred embodiments of this utility model have been described in detail above. It should be understood that those skilled in the art can make numerous modifications and variations based on the concept of this utility model without creative effort. Therefore, all technical solutions that can be obtained by those skilled in the art based on the concept of this utility model through logical analysis, reasoning, or limited experimentation on the basis of existing technology should be within the scope of protection defined by the claims.
