[0007] As a further technical solution of the present invention, a wire-aligning wheel for extruding the wire is installed in the fully automatic calibration device, and the wire-aligning wheel straightens the wire by extrusion.
[0008] As a further technical solution of the present invention, a wire pressing block for pressing the wire is installed in the wire pressing device, and the wire pressing block completes the setting of the drop of the wire length by cooperating with the front stripping mechanism.
[0009] As a further technical solution of the present invention, grooves for allowing wires to pass through are evenly distributed on the wire positioning block, and the wire positioning block sorts the pulled wires.
[0010] As a further technical solution of the present invention, the front stripping mechanism includes a front stripping motor, a transmission member, a gear, a front stripping frame, a rack, a moving block, a front stripping clamp, a front stripping connecting frame and a front stripping cylinder.

When processing long and short wires, the wire-calibrating wheel releases the pressure on the wire, so that the pulling force of the tension gun can be transmitted to the rear end of the anti-return device, so that the wire at the rear end of the anti-return device is always in a straightened state, so that it can be more stable when processing long and short wires, which is crucial to the processing quality of the wire. The anti-return device can prevent the wire under the tension of the tension gun from moving in the opposite direction under the pull of the tension gun, thereby improving the processing stability of the wire and further improving the accuracy of the wire processing length. This is very important for maintaining the accuracy of the wire processing length and is also the prerequisite for the wire processing accuracy. The front stripping mechanism can complete the drop setting of the wire length by cooperating with the wire positioning block and the wire pressing device, meet the cutting requirements of wires of different lengths, thereby increasing the processing range of the processing equipment and improving the practicality of the processing equipment; The back-stripping mechanism cooperates with the wire pulling mechanism and the knife holder to batch cut out wires with length differences, thereby quickly processing wires of different lengths and improving the processing efficiency and quality of the processing equipment.

DETAILED DESCRIPTION
[0020] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.
[0021] The specific implementation of the present invention is described in detail below in conjunction with specific embodiments.
[0022] like Figures 1 to 3 As shown, as an embodiment of the present invention, a long and short wire processing device is provided, including a device seat 1, one end of the device seat 1 is equipped with a full-automatic calibration device 3 for automatically straightening the wire, the other end of the device seat 1 is equipped with a wire pulling mechanism 9 for pulling the wire, and the device seat 1 is provided with a knife holder 5 for cutting the wire between the full-automatic calibration device 3 and the wire pulling mechanism 9, and also includes: A tension gun 2, which is arranged on one side of the equipment base 1 and close to the full-automatic calibration device 3. The tension gun 2 can tighten the wire in the processing process by cooperating with the full-automatic calibration device 3, so as to ensure that the wire always maintains appropriate tension during the processing, improve the processing accuracy of the wire, and further improve the processing quality and processing efficiency of the equipment, which is very important for the processing quality of the wire; The anti-return device 4 is installed on the equipment base 1 and is located on one side of the full-automatic calibration device 3. The anti-return device 4 can prevent the wire under the tension of the tension gun 2 from moving in the opposite direction under the pulling of the tension gun 2, thereby improving the processing stability of the wire and further improving the accuracy of the wire processing length. This is very critical for maintaining the accuracy of the wire processing length and is also a prerequisite for the wire processing accuracy. A front stripping mechanism 6, the front stripping mechanism 6 is installed on the equipment seat 1 and is located on one side of the anti-return device 4, a wire positioning block 10 is provided on one side of the front stripping mechanism 6, and a wire pressing device 7 fixed on the equipment seat 1 is provided on the side of the wire positioning block 10 away from the front stripping mechanism 6. The front stripping mechanism 6 can complete the drop setting of the set length of the wire by cooperating with the wire positioning block 10 and the wire pressing device 7 to meet the cutting requirements of wires of different lengths, thereby improving the processing range of the processing equipment and improving the practicality of the processing equipment; The rear-stripping mechanism 8 is installed on one end of the equipment base 1 close to the wire-pulling mechanism 9. The rear-stripping mechanism 8 can batch-cut wires with length differences by cooperating with the wire-pulling mechanism 9 and the tool holder 5, thereby quickly processing wires of different lengths and improving the processing efficiency and quality of the processing equipment.
[0023] like Figure 1 As shown, as a preferred embodiment of the present invention, a wire-calibrating wheel for extruding the wire is installed in the fully automatic calibration device 3, and the wire-calibrating wheel can realize the straightening of the wire by extrusion, so that when the length of the wire is subsequently adjusted, the accuracy of the wire processing length can be ensured, so that the wire pressing device 7 can position the wire more stably, and when processing long and short wires, the wire-calibrating wheel releases the pressure on the wire, so that the pulling force of the tension gun 2 can be transmitted to the rear end of the anti-return device 4, so that the wire at the rear end of the anti-return device 4 is always in a straight state, so that it can be more stable when processing long and short wires; When processing long and short wires, if the calibration wheel cannot release the pressure on the wire, the retreat of the front stripping mechanism 6 will cause the wire between the anti-return device 4 and the full-automatic calibration device 3 to cross-bend, which will not only damage the wire, but also affect the processing accuracy of the long and short wires and the processing of subsequent processes.
[0024] like Figures 1 to 3 As shown, as a preferred embodiment of the present invention, a wire pressing block 71 for pressing the wire is installed in the wire pressing device 7, and the wire pressing block 71 can complete the drop setting of the wire length by cooperating with the front stripping mechanism 6, so that the equipment can pull and cut wires of different lengths at the same time, thereby completing multi-length cutting of the wire.
[0025] like Figures 1 to 3 As shown, as a preferred embodiment of the present invention, the wire positioning block 10 is provided with grooves for the wires to pass through at equal intervals. The wire positioning block 10 can sort the pulled wires so that they will not be entangled during processing, thereby ensuring the processing efficiency and quality of the wires.
[0026] like Figures 1 to 3As shown, as a preferred embodiment of the present invention, the front stripping mechanism 6 includes a front stripping motor 61, a transmission member 62, a gear 63, a front stripping frame 64, a rack 65, a moving block 66, a front stripping clamp 67, a front stripping connecting frame 68 and a front stripping cylinder 69, the front stripping motor 61 is fixed on the equipment base 1, the output end of the front stripping motor 61 is fixedly connected to the gear 63 rotatably mounted on the front stripping frame 64 through the transmission member 62, the front stripping frame 64 is fixed on the equipment base 1, the gear 63 is meshed with the rack 65 slidably mounted on the front stripping frame 64, one side of the rack 65 is fixedly connected to the moving block 66 horizontally slidably mounted on the equipment base 1, the moving block 66 is rotatably mounted with a front stripping clamp 67, the front stripping cylinder 69 is mounted on the equipment base 1, and the output end of the front stripping cylinder 69 is mounted with a front stripping connecting frame 68, one end of the front stripping connecting frame 68 extends to the top of the moving block 66 and is movably connected to one end of the front stripping clamp 67.
[0027] In this embodiment, the wire pressing block 71 in the wire pressing device 7 positions and presses the wire of the required length, the front stripping cylinder 69 drives the front stripping connecting frame 68 to move vertically by telescoping, the front stripping connecting frame 68 drives the front stripping clamp 67 to rotate on the moving block 66, thereby pressing the outer wall of the wire on it, the front stripping motor 61 drives the gear 63 to rotate through the transmission member 62, the gear 63 drives the rack 65 to move on the front stripping frame 64, the rack 65 drives the moving block 66 and the front stripping clamp 67 thereon to move, at this time the wire located under the front stripping clamp 67 moves backward accordingly, and the wire pressed by the wire pressing block 71 moves forward relative to the wire positioning block 10, so that the pull-out length of the wire pressed by the wire pressing block 71 can be set; When it is necessary to pull out another length of wire again, the wire pressing block 71 in the wire pressing device 7 releases the wire after the above-mentioned drawn length is set, and the front stripping mechanism 6 drives all the wires therein to move to the initial position, including the wire after the above-mentioned drawn length is set. When all the wires move to the initial position, the wire pressing block 71 in the wire pressing device 7 positions and presses the corresponding wire, and repeats the above operation to set another length of wire. By repeating the above operation repeatedly, the drop setting of wires of different lengths can be completed, and the cutting requirements of wires of different lengths can be met, thereby improving the processing range of the processing equipment and improving the practicality of the processing equipment. When the front stripping cylinder 69 is opened, the wire is always in a stretched state due to the action of the tension gun 2. If the anti-return device 4 is not installed, the wire released by the front stripping cylinder 69 will be affected by the tension generated by the tension gun 2 and all pulled out of the wire positioning block 10, which will make it impossible to carry out subsequent processing of the wire normally.
[0028] In a preferred embodiment, the transmission member 62 preferably adopts a transmission structure composed of a synchronous belt and a synchronous wheel, and other transmission structures that meet actual use requirements may also be adopted.
[0029] like Figure 1 and Figure 4 As shown, as a preferred embodiment of the present invention, the rear stripping mechanism 8 includes a rear stripping frame 81, a rear stripping cylinder 82, a rear stripping connecting frame 83 and a rear stripping clamp 84, the rear stripping frame 81 is fixed on the equipment base 1, the rear stripping cylinder 82 is fixed on the rear stripping frame 81, the rear stripping clamp 84 is rotatably installed on one end of the rear stripping frame 81 close to the wire pressing device 7, the output end of the rear stripping cylinder 82 is connected to the rear stripping clamp 84 through the rear stripping connecting frame 83, and the rear stripping connecting frame 83 is slidably installed on the rear stripping frame 81.
[0030] like Figure 1 As shown, as a preferred embodiment of the present invention, the wire pulling mechanism 9 includes a moving module 91, a wire pulling cylinder 92, a wire pulling frame 93 and a wire pulling clamp 94. The moving module 91 is arranged on the side of the equipment base 1 away from the tension gun 2. The moving module 91 is equipped with a wire pulling frame 93. The wire pulling cylinder 92 is installed at one end of the wire pulling frame 93. The wire pulling clamp 94 is rotatably installed at the other end of the wire pulling frame 93. The output end of the wire pulling cylinder 92 is connected to the wire pulling clamp 94.
[0031] In this embodiment, the moving module 91 drives the wire drawing frame 93 to move in the direction close to the wire, and the wire drawing frame 93 drives the wire drawing cylinder 92 and the wire drawing clamp 94 thereon to move synchronously. When the drop of the wires of different lengths is set, the wire drawing cylinder 92 drives the wire drawing clamp 94 to close by telescoping, so that the wire drawing clamp 94 can press the wires of different lengths. At this time, the moving module 91 moves in the opposite direction, so that the wire drawing clamp 94 can pull the wires of different lengths out to the set total length. The rear stripping cylinder 82 drives the rear stripping connecting frame 83 to move by telescoping, and the rear stripping connecting frame 83 drives the rear stripping clamp 84 to close, so that the rear stripping clamp 84 can clamp the other end of wires of different lengths, and then the tool holder 5 can cut the wires between the rear stripping clamp 84 and the wire pulling clamp 94, so as to cut out wires with a length difference, which is convenient for the wires to be processed in the next step and improves the working efficiency and practicality of the processing equipment.
[0032] The working principle of the present invention is: After the wire passes through the tension gun 2, it enters the fully automatic calibration device 3, then enters the anti-return device 4, and finally passes through the wire positioning block 10, and the preliminary processing preparation of the wire is completed. When the wire needs to be processed into long and short wires, the fully automatic calibration device 3 is opened, so that the processed wire is subjected to the action of the tension gun 2, and the wire at the rear end of the anti-return device 4 is tightened; The wire pressing block 71 in the wire pressing device 7 positions and presses the wire of the required length, the front stripping cylinder 69 drives the front stripping connecting frame 68 to move vertically by telescoping, the front stripping connecting frame 68 drives the front stripping clamp 67 to rotate on the moving block 66, so as to press the outer wall of the wire thereon, the front stripping motor 61 drives the gear 63 to rotate through the transmission member 62, the gear 63 drives the rack 65 to move on the front stripping frame 64, the rack 65 drives the moving block 66 and the front stripping clamp 67 thereon to move, at this time the wire under the front stripping clamp 67 moves backward accordingly, and the wire pressed by the wire pressing block 71 moves forward relative to the wire positioning block 10, so that the pull-out length of the wire pressed by the wire pressing block 71 can be set; When it is necessary to pull out another length of wire again, the wire pressing block 71 in the wire pressing device 7 releases the wire after the above-mentioned set length is pulled out, and the front stripping mechanism 6 drives all the wires therein to move to the initial position, including the wire after the above-mentioned set length is pulled out. When all the wires move to the initial position, the wire pressing block 71 in the wire pressing device 7 positions and presses the corresponding wire, and repeats the above operation to set another length of wire. By repeating the above operation repeatedly, the drop setting of wires of different lengths can be completed to meet the cutting requirements of wires of different lengths; The moving module 91 drives the wire drawing frame 93 to move toward the direction close to the wire, and the wire drawing frame 93 drives the wire drawing cylinder 92 and the wire drawing clamp 94 thereon to move synchronously. When the drop of the wires of different lengths is set, the wire drawing cylinder 92 drives the wire drawing clamp 94 to close by telescoping, so that the wire drawing clamp 94 can press the wires of different lengths. At this time, the moving module 91 moves in the opposite direction, so that the wire drawing clamp 94 can pull the wires of different lengths to the set total length. The rear stripping cylinder 82 drives the rear stripping connecting frame 83 to move by telescoping, and the rear stripping connecting frame 83 drives the rear stripping clamp 84 to close, so that the rear stripping clamp 84 can clamp the other end of the wires of different lengths, and then the tool holder 5 can cut the wires between the rear stripping clamp 84 and the wire pulling clamp 94, so as to cut out the wires with different lengths, which is convenient for the wires to be processed in the next process. The above is the working principle of the long and short line processing equipment.
[0033] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
