Description

Technical Field

[0001] The present invention relates to the technical field of electric control cabinet processing, in particular to a connecting wire forming device. Background Art

[0002] When processing the electric control cabinet, for example, when connecting the electrical control switches, it is necessary to use a connecting wire with a C-shaped structure for processing. The conventional practice is that the operator first straightens the connecting wire through a connecting wire straightening device, cuts the connecting wire into the required length after straightening, and then performs a C-shape bend according to the distance between the electrical control switches. When bending, the operator uses pliers to bend the connecting wire. For connecting wires with smaller wire diameters, it is easy to bend, but the pliers may damage the insulation layer of the connecting wire during bending. For connecting wires with larger wire diameters, there is a problem of inconvenience in bending and forming. Secondly, the manual bending method is less efficient.

The inner end of the hard cutter 210 is a blade-shaped structure. Smooth sleeves are rotatably provided on the guide screw 214 and the connecting screw 209.

[0028] Two pairs of transverse holes 12 are provided at the upper end of the front wall plate 10 of the shell 1, and a first positioning screw 200 is passed through one pair of transverse holes 12. The outer end of the first positioning screw 200 is connected to the outer pressure plate 201 by a thread, and the inner wall of the outer pressure plate 201 is tightly attached to the front side of the front wall plate 10 of the shell 1. The outer end of the outer pressure plate 201 is bent with a vertical baffle 202, and the inner end of the first positioning screw 200 is connected to the inner plate 203 by a thread, and the inner wall of the inner plate 203 is tightly attached to the inner wall of the front wall plate 10 of the shell 1. The inner wall of the vertical baffle 202 plays a role in limiting the end of the connecting line, and in order to adapt to the bending and forming operations of connecting lines of different lengths, it is set to a position-adjustable form.

[0029] Another pair of transverse strip holes 12 are penetrated by a second positioning screw 205, the inner end of the second positioning screw 205 is connected to a fixed inner plate 206 by a thread, the inner wall of the fixed inner plate 206 is tightly attached to the inner wall of the front wall plate 10 of the shell 1, the outer end of the second positioning screw 205 is connected to a fixed outer plate 204 by a thread, the outer end of the fixed outer plate 204 is welded with an extension plate 207, and two pairs of vertical strip holes 208 are opened on the extension plate 207, which are connected by screws 209 and the smooth sleeve thereon. It is located in the vertical strip hole 208, and the hard cutter 210 and the inner vertical plate 230 are located on the inner side of the extension plate 207. A pair of limiting waist holes 213 are provided on the extension plate 207. The guide screw 214 and the smooth sleeve thereon are passed through the limiting waist holes 213. A threading hole is provided on the extension plate 207, and the threading hole is located at the hard cutter 210. The extension plate 207 not only guides and connects the components thereon, but also facilitates the forming operation of connecting wires of different lengths through its adjustable position.

[0030] During operation of this embodiment, the following adjustments need to be made, and there is no order of precedence between the adjustments. The adjustments are made according to the design specifications, and the reference data include the wire diameter of the connecting wire, the length of the connecting wire, the position of the bending point of the connecting wire, or the protruding length of the two ends of the connecting wire after bending, etc.

[0031] When adjusting according to the wire diameter of the connecting line: first loosen the locking screw 335, and then adjust the distance between the shaping wheel 332 and the swing pressure wheel 339. After adjustment, lock the position of the swing pressure wheel 339 by tightening the locking screw 335.

[0032] When adjusting according to the length of the connecting line: first loosen the first positioning screw 200 and the second positioning screw 205, and then adjust the distance between the vertical baffle 202 and the extension plate 207. When moving, it is necessary to ensure that the distance moved by the vertical baffle 202 and the extension plate 207 is equal. After moving, the position of the vertical baffle 202 and the extension plate 207 is locked by tightening the first positioning screw 200 and the second positioning screw 205. Such adjustment is mainly to make the protruding lengths of the two ends of the connecting line equal or the length difference is small after bending.

[0033] When adjusting according to the position of the bending point of the connecting line: the screw rod 315 is rotated by rotating the cap 318. When the screw rod 315 rotates, it will drive the wire sleeve 316, movable plate 317, movable inner plate 325, front plate 328, fixed wheel 332, and swing pressure wheel 339 thereon to move along the length direction of the slide rail 312, and finally achieve the fixed wheel 332 moving inward or outward by the same distance.

[0034] In this embodiment, when the connecting wire is bent, the connecting wire is pushed through the threading hole by the straightening device and the end is pressed against the inner wall of the vertical baffle 202, and then the conveying operation of the connecting wire is stopped. After the connecting wire is in place, the outer periphery of the connecting wire is tangent to the outer periphery of the fixed wheel 332, and at this time, the angle between the length direction of the swing plate 333 and the slide rail 312 is greater than 90 degrees.

[0035] Then start the hydraulic cylinder 308, which drives the rotating arm 310 to rotate. The rotation of the rotating arm 310 will drive the spline shaft 321 to rotate. The rotation of the spline shaft 321 will drive the driving bevel gear 324 and the gear 228 to rotate. The rotation of the driving bevel gear 324 will drive the rotation of the driven bevel gear 326. The rotation of the driven bevel gear 326 will drive the rotating shaft 329, the rotating arm 310, the adjusting arm 336, and the swinging pressure wheel 339 to rotate outward, so that the swinging pressure wheel 339 is close to the connecting line. During this process, the rotation of the gear 228 drives the rack 227 to move inward. During this process, the spring 224 is compressed, and during this process, the waist-shaped plate 221 moves inward, and the waist-shaped plate 221 pulls the L-shaped arm 217 to move. As the L-shaped arm 217 moves, the concave plate 215 moves. During the movement of the concave plate 215, the oblique hole 216 on the concave plate 215 acts on the moving end column 212, thereby causing the inner pressure outer plate 211 and the hard cutter 210 to approach the connecting line, and the connecting line is cut by the hard cutter 210. Then, the gear 228 and the inner end teeth of the rack 227 come into contact, so that the rack 227 will not move forward. Thereafter, the swing pressure wheel 339 will act on the connecting line and bend it into a C-shaped structure. After completion, the connecting line is removed, and the swing pressure wheel 339 and the hard cutter 210 return to their initial positions.
