[0001] The application relates to the technical field of spring manufacturing, and in particular to a spring processing equipment. BACKGROUND

[0002] With the development of manufacturing industry, springs, as one of the important basic parts, play an important role in many industries such as automobiles, aerospace, electronics, etc. In recent years, with the progress of automation technology and precision machinery, more spring processing equipment with high automation degree has appeared on the market. These devices significantly improve production efficiency and product quality, and reduce costs.

[0003] The commonly used spring processing equipment is a spring winding machine, which is a mechanical device specially used for manufacturing various spiral springs. The spring winding machine can produce springs meeting the design requirements by accurately controlling the winding angle and speed of the wire. This device plays an important role in industrial production and is the core technical equipment of the spring manufacturing industry.

[0004] Although the spring winding machine plays an important role in spring manufacturing as a spring processing equipment, in actual use, they can usually only produce single type of springs and often cannot flexibly cope with the spring processing needs of different diameters, lengths and materials, greatly limiting the production efficiency and product diversity, resulting in low spring production efficiency and low product qualification rate. Therefore, the application provides a spring processing equipment. Content of the utility model

[0008] By adopting the above technical solution, the spring wire is first inserted between multiple guide tubes 1 and 2. Then, the adjusting component drives the guide tube 1 to make fine adjustments according to the wire diameter. The clamping of the wire by the guide tubes 1 and 2 ensures that the wire is not disturbed during linear transmission, ensuring that the wire smoothly enters the corresponding roller. The forming mechanism can rotate the roller of the corresponding shape. Then, the auxiliary component is activated to drive the corresponding roller to rotate continuously, and the moving component is activated at the same time to push the roller forward slowly. This causes the spring to be deformed by pressure and gradually form a stable spiral structure. When it is necessary to produce springs of other different diameters and lengths, the position of the corresponding roller can be precisely adjusted by rotating the turntable. This greatly improves the versatility and adaptability of the spring processing equipment, and can flexibly meet the processing needs of springs of different diameters, lengths or materials, significantly improving processing accuracy and stability.

[0019] Further, the plurality of rollers are made of hard alloy steel, and the plurality of guide pipes one and the guide pipes two are made of stainless steel pipes.

[0042] Referring to Figure 1 and Figure 2 , the adjusting assembly comprises an embedded slot 16 opened in one side of the main rack 1, a plurality of sliding grooves 15 are slidably connected with adjusting blocks 17 inside, a plurality of guide pipes two 3 are rotatably connected on one side of the plurality of adjusting blocks 17, a plurality of adjusting blocks 17 are rotatably connected with screw rods one 18 on the top, the screw rods one 18 are fixedly connected with handles 19 on the top, and the screw rods one 18 are threadedly connected at the connection between the sliding grooves 15 and the embedded slot 16.

[0043] In use, first insert the spring wire between the plurality of guide pipes one 2 and the guide pipe two 3, then rotate the plurality of handles 19 to drive the corresponding screw rods one 18 to rotate, so as to drive the adjusting blocks 17 to move in the sliding grooves 15 by the rotation of the screw rods one 18, at this time the movement of the adjusting blocks 17 will drive the plurality of guide pipes one 2 to fine adjust according to the diameter of the wire, so that the clamping of the guide pipe one 2 and the guide pipe two 3 on the wire can ensure that the wire is not disturbed when transmitting in a straight line, and ensure that the wire enters the corresponding roller 14 smoothly.

[0046] The implementation principle of the spring processing equipment is as follows: in use, first, the servo motor one 11 is started to drive the rotating disc 12 to rotate, and the positions of the plurality of rollers 14 are adjusted through the rotating disc 12. Since the shapes and sizes of the plurality of rollers 14 are different, when a spring of a certain type needs to be processed, the roller 14 of a corresponding shape is rotated and moved to a position where the end of the guide pipe one 2 and the guide pipe two 3 are on the same horizontal line, and then the roller 14 is stopped. At this time, the spring wire can be inserted between the plurality of guide pipes one 2 and the guide pipe two 3, and then the handles 19 are twisted to drive the corresponding lead screw one 18 to rotate, so that the lead screw one 18 is rotated to drive the adjusting block 17 to move in the sliding groove 15.

Then, the electric push rod three 23 is started to drive the sliding block 21 to move forward and be pushed out, so that the square block 24 on the output end of the top servo motor two 22 enters the corresponding square groove 25. Then, the servo motor two 22 is started to drive the connecting shaft 13 in the corresponding roller 14 to rotate continuously, and at the same time, the servo motor three 28 is also started to drive the lead screw two 27 to rotate. At this time, the guide of the guide rod 30 makes the moving block 29 move slowly on the lead screw two 27, and the movement of the moving block 29 drives the top base 10 to move together, so as to push the roller 14 to move forward and be pushed out slowly. At this time, the rotation and pushing out of the roller 14 and the abutment of the auxiliary abutting plate 7 can make the spring be deformed under pressure and gradually form a stable spiral structure. When the forming is completed, the electric push rod two 8 is started to drive the blade 9 to cut the wire, so as to form a single spring product.

[0047] In addition, when springs with different diameters and lengths are needed to be produced, the positions of the corresponding rollers 14 can be accurately adjusted through the rotation of the rotating disc 12, thereby greatly improving the versatility and adaptability of the spring machining equipment, flexibly coping with the spring machining requirements of different diameters, lengths or materials, greatly improving the machining precision and stability, effectively reducing the quality problems caused by unstable equipment, and improving the yield;

[0048] Secondly, in the whole processing flow, the Siemens PLC inside the controller 5 can continuously collect various signals, and once an abnormal situation is found, an alarm will be sent immediately.
