Description

Technical Field

[0001] The invention relates to the technical field of coil spring production, and in particular to a device and a process for synchronously coiling springs at both ends of a carbon brush spring. Background Art

[0002] A carbon brush spring is an electrical component that combines the high conductivity of a carbon brush with the high elasticity of a spring. It is commonly used in motors, generators, transformers and other equipment. It has good conductivity, wear resistance and stability. As an electrical connector, it can stably transmit electrons to ensure the normal operation of motors, generators and other equipment. The main functions of a carbon brush spring include providing power and signal transmission, maintaining stable contact, optimizing current transmission efficiency, reducing friction and wear, and reducing current loss. In addition, the elastic properties of the carbon brush spring can properly compensate and adjust the carbon brush to maintain good contact between the carbon brush and the rotor, extending the service life of the carbon brush and the equipment.

[0003] In the process of winding springs, one end of the raw material is usually a free end, and then the free end of the raw material is wound through the feeding mechanism and the guide mechanism, and finally cut off to form a product. However, this production method is difficult to produce carbon brush springs with both ends of the winding structure;

[0004] In addition, the existing coil spring production equipment has a discontinuous production process, which requires frequent start and stop of its feeding device. However, the raw material coil of the coil spring is usually heavy, which makes the inertia larger during the start and stop process. During the frequent start and stop process, the raw material belt will shake, which may easily cause the raw material belt to shift, bend or break, affecting the quality of the product.

[0005] At the same time, after using the existing coil spring production equipment to produce coil springs, in order to ensure product quality, subsequent manual screening is required to eliminate defective products with cracks. This process is not only time-consuming and labor-intensive, but also manual inspection has limited ability to identify microcracks and is prone to missed detection. Summary of the invention

[0006] The purpose of this section is to summarize some aspects of embodiments of the present invention and briefly introduce some preferred embodiments. Some simplifications or omissions may be made in this section and the specification abstract and the invention title of this application to avoid blurring the purpose of this section, the specification abstract and the invention title, and such simplifications or omissions cannot be used to limit the scope of the present invention.

[0010] As a preferred solution of the synchronous spring winding device at both ends of the carbon brush spring described in the present invention, it also includes a material guide component, which includes a partition vertically fixed inside the fifth installation frame, a material pushing electric cylinder is fixed on the back of the partition, and a material pusher is fixed on the output end of the material pushing electric cylinder, a fixing rod is fixed on the bottom of the fifth installation frame, a lifting electric cylinder is fixed on the bottom center of the fixing rod, a movable rod is fixed on the output end of the lifting electric cylinder, and two slides are symmetrically fixed on the top of the movable rod, and guide groove plates are fixed on the tops of the two slides, and a through hole can be formed through the two guide groove plates.

[0011] The beneficial effects of the present invention are as follows: the upper module is pushed downward by the output end of the stamping electric cylinder to stamp the middle part of the raw material sheet, and then the two lower pressure electric cylinders are started to push down the lower pressure seat, so that the upper clamping rod and the lower clamping rod clamp the two ends of the raw material sheet, and then the double-thread screw is driven to rotate by starting the moving motor, and then under the action of the thread, the two second sliders slide toward each other along the slide plate, and at the same time, the curling motor is started, and then the clamp is driven to rotate by the driving gear and the driven gear, so that the two ends of the raw material can be synchronously rolled up to complete the product processing, and finally the processed product can be pushed out by starting the pushing electric cylinder to push the pusher, so that the carbon brush spring with a winding structure at both ends can be produced in one time, thereby improving the production efficiency.

[0012] In view of the fact that the existing spring winding equipment needs to be constantly started and stopped during operation, which leads to the problem of shaking and causing damage to the raw material belt, a synchronous spring winding equipment for both ends of the carbon brush spring is proposed.

[0013] To solve the above technical problems, the present invention also provides the following technical solutions: the first conveyor includes a first mounting frame fixedly arranged on the front side of the mounting plate, the interior of the first mounting frame is rotatably connected to two first rotating shafts in a vertical direction, the outsides of the two first rotating shafts are fixedly provided with first conveying wheels and first gears, and the two first gears are meshed with each other, a first driving motor is fixedly arranged on the front side of the first mounting frame, and one of the first rotating shafts is fixedly arranged at the output end of the first driving motor, and the raw materials can be moved at a uniform speed through the two first conveying wheels; the second conveyor includes a second mounting frame fixedly arranged on the front side of the mounting plate, the interior of the second mounting frame is rotatably connected to four corners corresponding to four corners, the outsides of the four second rotating shafts are fixedly provided with second conveying wheels and second gears, and the two second gears in the vertical direction are meshed with each other, the interior of the second mounting frame is rotatably connected to the driving shaft, the outside of the driving shaft is fixedly provided with a third gear, and the third gear is connected to two adjacent second The gears are meshed, and a second drive motor whose output speed is faster than that of the first drive motor is fixedly provided on the front side of the second mounting frame, and the drive shaft is embedded in the output end of the second drive motor. A mounting seat is fixedly provided on the side of the second mounting frame facing the slide slot plate. By virtue of the second drive motor having a speed faster than that of the first drive motor, the bent raw material belt can be straightened so that the conveying process maintains a uniform speed; the fixed component includes a third mounting frame fixedly provided on the other side of the second mounting frame, a sliding slot is provided on the front side of the third mounting frame, and two first sliders are slidably connected inside the sliding slot, and a clamp is fixedly provided on one side of the two first sliders located on the inner side of the second mounting frame, and an adsorption seat is fixedly provided on the other side of the two first sliders, and an electromagnet is fixedly provided on the middle part of the front side of the third mounting frame, and a pulling spring is fixedly provided between the opposite ends of the two first sliders and the inner wall of the sliding slot. Fixing the raw material belt by the clamp can make the cut raw material belt more stable and avoid falling off.

[0015] Another beneficial effect of the present invention is that during the processing of the cut raw material sheets, the first drive motor continues to run, while the second drive motor stops running, forming a curved raw material belt between the fixed component and the first conveyor. After the processing is completed, the second drive motor is started and the electromagnet is powered off. Since the rotation speed of the second drive motor is faster than that of the first drive motor, the curved raw material belt can be straightened, thereby maintaining a uniform speed during the conveying process and avoiding damage caused by shaking due to repeated starting and stopping.

[0016] In view of the existing spring winding equipment, in order to ensure product quality after production, staff need to conduct another inspection, which makes production efficiency low and prone to missed inspections, making it difficult to ensure product quality.

[0018] Another beneficial effect of the present invention is that the raw material belt can be detected by the crack detector. When cracks appear in the raw material, the fourth gear is driven to rotate by starting the sorting motor, and then the third shaft is driven to rotate counterclockwise by the meshing fifth gear, so that the material guide trough is tilted toward the waste box, and the defective products after processing can be automatically sorted out, thereby ensuring product quality.

[0063] Example 3

[0064] Reference Figure 1 and Fig.16 , which is the third embodiment of the present invention, is based on any of the above embodiments, except that, in order to automatically sort defective products, a crack detector 907 is provided to detect the raw material belt, and then the inclination direction of the material guide trough 902 is changed so that the product falls into the corresponding collection box.
