Description

Technical Field

[0001] The invention relates to the field of coil spring processing, and in particular to an automatic coil spring winding and forming device. Background Art

[0002] A coil spring is a spiral part made of elastic metal wire. Its working principle is to store energy through elastic deformation to achieve various mechanical movements. When an external force acts on the coil spring, it deforms elastically, converting the external force into elastic potential energy, and quickly releases the stored elastic potential energy as the external force disappears, thereby driving the mechanical equipment to move.

[0003] The processing of coil springs usually includes wire drawing, cutting, and forming. During the forming process, the filaments need to be bent and wound according to the requirements of the coil spring to form the spiral shape of the coil spring.

[0019] 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.

[0020] The specific implementation of the present invention is described in detail below in conjunction with specific embodiments.

[0021] See also Figures 1 to 8 The embodiment of the present invention provides an automatic coil spring winding and forming device, the automatic coil spring winding and forming device includes a workbench 1, and also includes: The ring feeding unit 2 includes a feeding box 21, a feeding track 22 and a clamping type transfer mechanism 23; the feeding box 21 is located at one side of the workbench 1, the feeding track 22 is installed on the feeding box 21, and the clamping type transfer mechanism 23 is installed at one side of the workbench 1 for conveying the rings; The coil spring feeding and molding unit 3 includes a feeding transfer mechanism 31, a feeding table 32 and a crimping die 33; the feeding transfer mechanism 31, the feeding table 32 and the crimping die 33 are all installed on the workbench 1, and a coil spring is placed on the feeding table 32; The ferrule and the coil spring can be transferred to the crimping die 33 through the feeding transfer mechanism 31 to achieve bending processing and binding and fixing of the coil spring.

[0022] It should be noted that: the device includes a ring feeding unit 2 and a coil spring feeding and forming unit 3, so the entire equipment integrates the feeding of the ring, the feeding and processing of the coil spring. Compared with the traditional spring winding machine, the production cost will be lower, and the processing efficiency will be higher when the coil spring processing operation is carried out, while ensuring the processing quality of the coil spring.

[0023] In the embodiments of the present invention, please refer to Figure 3 The loading box 21 includes an outer box 211, which is fixed to the ground through a support. An inner box 212 is arranged inside the outer box 211. A vertically arranged and rotatable spiral feeding plate 213 is arranged inside the inner box 212. The top of the spiral feeding plate 213 is flush with the top of the inner box 212. A guide plate 214 is arranged on the outer wall of the inner box 212, and a first baffle 215 corresponding to the feeding end of the guide plate 214 is also arranged; Among them, a first jet pipe 217 and a second jet pipe 218 are fixed on the outer box 211, and a detection head 216 is fixed on the inner box 212. The detection head 216 faces the guide plate 214 and is used to detect whether the rings on the guide plate 214 overlap. When overlapping, the first jet pipe 217 sprays gas for separation, and the output end of the second jet pipe 218 faces the unloading direction of the guide plate 214.

[0024] It should be noted that: when the ferrule is being fed, the ferrule is concentrated on the spiral feeding plate 213, and the ferrule is transported by the rotation of the spiral feeding plate 213. When the ferrule moves to the topmost position of the spiral feeding plate 213, it will fall into the gap between the outer box 211 and the inner box 212. At the same time, under the limitation of the first baffle 215, the ferrule will fall onto the guide plate 214 and roll along the inclined guide plate 214. When the ferrule moves on the guide plate 214 to the position of the detection head 216, the detection head 216 performs overlapping detection. When it is detected that the ferrule is overlapping, the first jet pipe 217 quickly sprays gas to blow away the overlapping ferrules with the airflow to ensure normal subsequent feeding.

[0025] In the embodiments of the present invention, please refer to Figure 4 The feeding track 22 includes a bottom support plate 221, which is fixed on the outer box 211 and extends along the tangent direction of the outer box 211. A track plate 222 is fixed on the bottom support plate 221. The track plate 222 has a groove for the ring to move. A second V-shaped baffle 223 is fixed at the upper end of the track plate 222 near the guide plate 214, and a mounting seat 224 is fixed on the other end, and a stopper needle 225 is fixed on the mounting seat 224.

[0026] It should be noted that after the ferrule moves from the guide plate 214 to the track plate 222 , the second jet pipe 218 quickly ejects airflow, which provides a force to the ferrule to achieve movement of the ferrule on the track plate 222 until the ferrule contacts the stop needle 225 .

[0027] In the embodiments of the present invention, please refer to Figure 5 The clamping transfer mechanism 23 includes a base frame 231, which is fixed on the workbench 1. A first hydraulic cylinder 232 is fixed on the upper end of the base frame 231. The output end of the first hydraulic cylinder 232 faces the vertical direction, and a first mounting plate 233 is fixed on the output end. A second hydraulic cylinder 234 is fixed on the upper end of the first mounting plate 233. The output end of the second hydraulic cylinder 234 faces the unloading end of the track plate 222, and a second mounting plate 235 is fixed on the output end. A third hydraulic cylinder 236 is fixed on the upper end of the second mounting plate 235. Two fixing clamps 237 are fixed on the third hydraulic cylinder 236, and the two fixing clamps 237 are driven by the third hydraulic cylinder 236 to move toward or away from each other, and the two fixing clamps 237 are both Y-shaped.

[0028] It should be noted that after the ferrule is blocked by the blocking needle 225 , the second hydraulic cylinder 234 drives the second mounting plate 235 to move toward the position of the ferrule, and then the third hydraulic cylinder 236 is used to control the two fixing clamps 237 to clamp the ferrule.

[0029] In the embodiments of the present invention, please refer to Figure 6 and Figure 7 The feeding transfer mechanism 31 includes a fixed plate 311, which is fixed to the upper end of the workbench 1. A first motor 312 is fixed on one side of the fixed plate 311. The output end of the first motor 312 passes through the fixed plate 311 and is fixed to a third mounting plate 313. A fourth hydraulic cylinder 314 and a fifth hydraulic cylinder 318 are fixed on the other side of the third mounting plate 313. The output ends of the fourth hydraulic cylinder 314 and the fifth hydraulic cylinder 318 face opposite directions. A fourth mounting plate 315 is fixed to the output end of the fourth hydraulic cylinder 314. A cylindrical positioning seat 316 is fixed on the fourth mounting plate 315. A plurality of ring-shaped rack rods 317 that can move synchronously in the radial direction are arranged at the other end of the positioning seat 316. A fifth mounting plate 319 is fixed to the output end of the fifth hydraulic cylinder 318. A cylindrical and radially expandable boss 3110 is fixed on the other side of the fifth mounting plate 319. Meanwhile, the crimping die 33 is located at one side of the fixed plate 311 and is used for curling the coil spring. A conveyor belt 4 is also installed at the upper end of the workbench 1 , and the conveyor belt 4 is close to the crimping die 33 .

[0030] It should be noted that: when the coil spring is being fed, the third mounting plate 313 is driven to rotate by the first motor 312, so that the fifth hydraulic cylinder 318 faces the direction of the feeding table 32, and then the fifth mounting plate 319 is driven to move in this direction until the boss 3110 contacts and fixes the coil spring material. After fixation, the third mounting plate 313 is rotated so that the output end of the fifth hydraulic cylinder 318 faces downward, and then the coil spring material can be transferred to the crimping die 33 to process the coil spring material. When the ferrule is transferred by the feeding transfer mechanism 31, the third mounting plate 313 is driven to rotate by the first motor 312, so that the fourth hydraulic cylinder 314 is directed toward the position of the fixing clamp 237, and then the fourth mounting plate 315 is driven to move in this direction until the rack rod 317 passes through the ferrule, and then the ferrule is fixed by expansion. After the ferrule is fixed, the third mounting plate 313 is rotated so that the output end of the fourth hydraulic cylinder 314 is directed downward, so that the ferrule can be transferred to the crimping die 33 and put on the outside of the coil spring to bind and fix the coil spring; A conveyor belt 4 is also provided on the workbench 1. After the coil springs are processed and bundled, the coil springs can be transferred to the conveyor belt 4 through a clamping transfer structure, and then the finished product is transferred out through the conveyor belt 4, thereby realizing continuous and efficient processing of the coil springs.

[0031] In the embodiments of the present invention, please refer to Figure 8 The feeding table 32 includes a support frame 321, which is fixed to the upper end of the workbench 1. A horizontally arranged bracket 322 for preventing the spring from winding is fixed on the support frame 321. A second motor 323 is also fixed on the support frame 321. A screw rod 324 is fixed to the output end of the second motor 323. The screw rod 324 is arranged parallel to the bracket 322. A push plate 325 is threadedly connected to the screw rod 324. The push plate 325 also extends to the inside of the bracket 322 and can move along the length direction of the bracket 322.

[0032] It should be noted that the push plate 325 can be driven to move by the second motor 323 , and the push plate 325 can push the coil spring material on the bracket 322 to move, so as to achieve continuous loading and facilitate the fixing and transfer of the coil spring material by the boss 3110 .
