Description

Technical Field

[0001] This utility model relates to the technical field of electromagnetic wire production equipment, and in particular to a winding device for electromagnetic wire production. Background Technology

[0002] The winding device for producing electromagnetic wire is a core automated equipment at the end of the electromagnetic wire manufacturing process. Its main function is to wind electromagnetic wire (such as enameled wire, silk-covered wire, etc.) that has been processed through drawing, annealing, insulation coating and other processes into a coil in an orderly manner according to preset tension, arrangement density and coil diameter requirements, forming a regular and tight coil. It is a special equipment that can ensure that the coil is free from problems such as overlapping, messy, and thinning after winding, and provides qualified raw material coils for subsequent winding processes of electromagnetic components such as motors and transformers. It is a key link connecting electromagnetic wire production and downstream applications.

[0003] However, existing equipment often requires manual handling of the wire reels. First, the clamping structure spacing must be manually adjusted according to the reel size, and then the reels are placed one by one at the loading station. After one reel is loaded, production must be paused to wait for the next reel to be manually moved into place, resulting in low loading efficiency. Furthermore, the winding mechanism of existing equipment is mostly designed with fixed specifications, which can only adapt to reels with a single or a few types of center slot sizes. It cannot flexibly meet the production needs of different specifications of electromagnetic wire. If the reel size needs to be changed, the core components of the winding mechanism (such as clamping heads and positioning sleeves) must be disassembled and replaced with parts of the corresponding size. The operation is complicated. After replacing the parts, the coaxiality, clamping force and other parameters of the winding mechanism must be recalibrated. The debugging process is time-consuming, and the downtime for debugging accounts for a large proportion of the equipment, which greatly affects the production efficiency.

[0004] Therefore, we propose a winding device for producing electromagnetic wire to solve the above problems. Utility Model Content

[0025] In this embodiment, a sloping metal block 17 is fixedly installed on one side of the feeding bin 1, and a pushing cylinder 11 is fixedly installed on the top of the feeding bin 1.

The bottom end of the threaded rod 8 extends out of the adjustment head 7, making it convenient for the operator to rotate the threaded rod 8 through the extended end.

[0027] In this embodiment, four evenly distributed extension grooves are provided on the outer side of the adjusting head 7. The four extension grooves are connected to the same adjusting chamber. Extension metal blocks 10 are slidably installed on the inner side of each of the four extension grooves. Linkage grooves are provided on one side of each of the four extension metal blocks 10.

[0029] In this embodiment, the bottom of the feeding hopper 1 is provided with four top support openings. Lifting cylinders 19 are fixedly installed on the inner side of each of the four top support openings. The parameters of the four lifting cylinders 19 are the same. The piston end of the four lifting cylinders 19 is fixedly installed with the same top support plate 18, so that the same top support plate 18 can be driven to rise by the four lifting cylinders 19, thereby supporting the wire reel to move upward.

[0030] In this embodiment, multiple limiting rods 22 evenly distributed along the longitudinal direction are fixedly installed on the inner side of both adjusting bases 16. The multiple limiting rods 22 are respectively located above the corresponding limiting protrusions, which facilitates limiting the limiting protrusions.

[0031] In this embodiment, each of the multiple support protrusions has two adaptation grooves on its top, and a guide shaft 24 is fixedly installed on the inner side of each of the multiple adaptation grooves. Each of the multiple support protrusions has two limiting wheels 23 slidably installed on its top, and each of the multiple limiting wheels 23 has a sliding protrusion at its bottom. Each of the multiple sliding protrusions is slidably sleeved on the corresponding guide shaft 24. Each of the multiple guide shafts 24 has two springs 25 sleeved on it. The two ends of the two springs 25 located on the same guide shaft 24 are fixedly connected to one side of the corresponding sliding protrusion and one side of the inner wall of the adaptation groove, respectively, so as to apply traction force and thrust force to the sliding protrusion at the same time.

[0032] Working principle: When winding the electromagnetic wire, the operator first starts the adjusting servo motor 13 according to the size of the wire spool. The adjusting servo motor 13 drives the forward and reverse toothed ball screw 14 to rotate, which in turn drives the two sliders 15 to move closer to each other. The two sliders 15 move closer to each other, which in turn drives the corresponding adjusting bases 16 to move closer to each other. Then, the wire spool is pushed into the loading bin 1 through the inlet. The four lifting cylinders 19 are activated. The parameters of the four lifting cylinders 19 are consistent, so they synchronously drive the same top support plate 18 and the wire spool to rise. The rising wire spool pushes the two corresponding loading brackets 21, causing them to rotate around the corresponding fixed axis 20. The outer side of the loading bracket 21 is provided with a limiting protrusion and a supporting protrusion. At this time, the limiting protrusion... The coil moves away from the limit rod 22, and the support protrusions rise simultaneously. When the coil rises to a certain height, it passes over the support protrusions of the two upper feeding brackets 21. The feeding brackets 21, which were originally lifted, lose their supporting force and return to their horizontal position under gravity. At this time, the lowermost coil is supported by the two upper feeding brackets 21. The uppermost coil is pushed by the pushing metal block 12 driven by the pushing cylinder 11. After passing the sloping metal block 17, it moves to the conveyor table 2 by inertia and gravity. The coils in the feeding bin 1 then move upwards to fill the gap through the above steps, thus achieving autonomous feeding. During the feeding process, when the coil is supported by the two support protrusions, to ensure that the coil is in the upper position... At the center of hopper 1, two support protrusions each have two adapting grooves. The bottoms of the four limiting wheels 23 each have sliding protrusions, which are slidably installed inside their respective adapting grooves. Both sides of the four sliding protrusions are fixedly connected to corresponding springs 25. The other ends of the springs 25 are fixedly connected to the inner wall of one side of the corresponding adapting groove. The traction and thrust applied by the two springs 25 to the same limiting wheel 23 keep the limiting wheel 23 in the center of its corresponding adapting groove. When a wire reel is supported on the support protrusion, the two limiting wheels 23 on the same side apply a squeezing force, and the four limiting wheels 23 squeeze the same wire reel, positioning it at the center of hopper 1. When the coil moves to the center of the winding base 5 via the conveyor belt on the conveyor table 2, the operator turns off the conveyor belt and, according to the center slot of the coil, uses a tool to rotate the threaded rod 8. The rotation of the threaded rod 8 causes the extrusion metal block 9 to move upward, thereby causing the four extension metal blocks 10 to move radially along the corresponding extension grooves to match the center slot of the coil. Then, the electric push rod 4 is activated, which causes the winding base 5 and the adjusting head 7 to move downward, so that the adjusting head 7 is located in the center slot of the coil. At this time, the operator winds one end of the electromagnetic wire onto the coil and then starts the winding servo motor 6. The winding servo motor 6 drives the adjusting head 7 to rotate, which in turn drives the coil to rotate to perform the winding of the electromagnetic wire.

[0033] The technological advancements of this invention compared to existing technologies are as follows: it enables precise adjustment of the wire reel clamping distance. Furthermore, the composite structure of the lifting cylinder 19 and the feeding bracket 21 allows the wire reel to autonomously fill in the gaps, reducing manual handling and operation steps, significantly improving feeding efficiency, and reducing the burden on workers. Additionally, the radial position of the extending metal block 10 can be adjusted by rotating the threaded rod 8 to accommodate wire reels with different center slot sizes, solving the problems of limited wire reel compatibility and cumbersome replacement and debugging in traditional equipment, thus greatly improving production efficiency.
