Description

Technical Field

[0001] This utility model relates to the field of transformer technology, and in particular to a clamping device for foil-wound coil processing. Background Technology

[0002] During the foil winding process, the winding machine is responsible for winding tin foil or copper foil onto the transformer coil. The transformer coil has a semi-circular shape at both ends and a rectangular shape in the middle. When the winding machine winds the foil from the curved end of the transformer coil to the straight section in the middle, the foil cannot be immediately straightened and adhered to the coil. It still has a slight curvature, which causes a void between the foil and the straight section in the middle of the transformer coil.

[0003] Regarding the problem of foil not being able to be straightened, resulting in hollow areas, in actual operation, the operator usually uses a rubber hammer to hammer the hollow areas of the foil until the foil completely adheres to the transformer coil. However, in this operation, the hammering area of ​​the rubber hammer is too small, and manual repeated hammering is required. As a result, the worker will consume a lot of physical strength, which will reduce the control of the foil winding machine and cause operational risks. Utility Model Content

[0004] The technical problem to be solved by this utility model is to overcome the defects of the prior art and provide a clamping device for foil-wound coil processing.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0006] This utility model discloses a pressing device for foil winding coil processing. The pressing device includes a support rod, which is inclinedly arranged on two support frames of a winding machine. A rotating shaft is provided at the end of the support rod, and a compaction mechanism is connected to the rotating shaft. The compaction mechanism rotates along the rotating shaft to impact the foil material.

[0007] As a preferred embodiment of this utility model, one end of the rotating shaft extends out of the support rod, and a power rod is provided on the portion of the rotating shaft extending out of the support rod.

[0008] As a preferred embodiment of the present invention, the compaction mechanism includes a sliding component, which is disposed on a rotating shaft between two support rods and is located near the support rods.

[0009] As a preferred technical solution of this utility model, a sliding groove is provided on the top of the sliding component, and a plurality of first fixing holes are provided on both sides of the sliding groove. The first fixing holes on both sides are symmetrically arranged. A plurality of rollers are installed on the bottom surface of the sliding groove, and the rolling direction of the rollers is the axial direction of the sliding groove.

[0010] As a preferred technical solution of this utility model, the compaction mechanism further includes a striking component, which includes a striking rod, a crossbar and a striking head. There are two striking rods, and their bottoms are respectively set in sliding grooves at both ends [1]. The bottom of the striking component is T-shaped, and a second fixing hole is provided in the middle of the bottom of the striking component. The diameter of the second fixing hole is the same as the diameter of the first fixing hole. The striking crossbar is set in the middle of the two striking rods. The top ends of the two striking rods are fixedly connected to the striking head. The length of the striking head is the same as the width of the foil. The front part of the striking head is semi-circular.

[0011] As a preferred embodiment of this utility model, the power rod includes a first telescopic rod, a second telescopic rod, and a handle. The first telescopic rod is sleeved inside the second telescopic rod, and the handle is located at the top of the first telescopic rod.

[0012] As a preferred embodiment of this utility model, the grip is made of rubber.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] 1. A bolt is inserted between the first fixing hole and the second positioning hole to fix the striking component and the sliding component. The multiple sets of first positioning holes ensure that the striking component can move on the sliding component to compact the foil at different positions on the winding machine. The T-shaped design is intended to widen the force-bearing area of ​​the striking component. Firstly, the cooperation between the second fixing holes can only ensure that the striking component does not move horizontally in the sliding groove, while the widened T-shaped design at the bottom can prevent its vertical movement. Secondly, during the process of the striking component striking and compacting the foil, the striking rod will bear a large amount of shear force. The widened T-shaped design can increase the shear force bearing capacity. The crossbar is fixedly connected to the striking rod.

[0015] 2. The first telescopic rod is sleeved in the second telescopic rod. When necessary, the first telescopic rod can extend out from the second telescopic rod to increase the torque of the torque-driven rod and reduce the manpower consumption of the operator. Attached Figure Description

[0022] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0023] In the attached diagram, all identical reference numerals refer to the same components.

[0024] like Figures 1-4 As shown, this utility model provides a pressing device for foil-wound coil processing. The pressing device for foil-wound coil processing is characterized in that, in this utility model, the support rod 1 is fixed to the two support frames of the winding machine by welding; the rotating shaft 2 on the support rod 1 passes through the support rod 1 and is movably connected to the support rod 1 by bearing; the compaction mechanism 3 is connected to the rotating shaft 2 by welding.

[0025] In an optional embodiment, one end of the rotating shaft 2 extends out of the support rod 1, and the portion of the rotating shaft 2 extending out of the support rod 1 is provided with a power rod 4.

[0026] It should be noted that the operating lever drives the striking component 9 to impact the foil.

[0027] In an optional embodiment, the compaction mechanism 3 includes a sliding component 5, which is disposed on a rotating shaft 2 between two support rods 1 and is located near the support rods 1.

[0028] It should be noted that the sliding component 5 is positioned on the rotating shaft 2 near the support rod 1 to ensure that the top striking head 12 is subjected to uniform force, thus avoiding stress concentration that could cause the striking component 9 to break.

[0029] In an optional embodiment, a sliding groove 6 is provided above the sliding component 5, and a plurality of first fixing holes 7 are provided on both sides of the sliding groove 6. The first fixing holes 7 on both sides are symmetrically arranged. A plurality of rollers 8 are installed on the bottom surface of the sliding groove 6. The rolling direction of the rollers 8 is the axial direction of the sliding groove 6. The compaction mechanism 3 also includes a striking component 9. The striking component 9 includes striking rods 10, crossbars 11 and striking heads 12. There are two striking rods 10, and their bottoms are respectively set in the sliding grooves 6 at both ends. The bottom of the striking component 9 is T-shaped. A second fixing hole 13 is provided in the middle of the bottom of the striking component 9. The diameter of the second fixing hole 13 is the same as the diameter of the first fixing hole. The crossbar 11 is set in the middle of the two striking rods 10. The top ends of the two striking rods 10 are fixedly connected to the striking head 12. The length of the striking head 12 is the same as the width of the foil. The front part of the striking head 12 is semi-circular.

[0030] It should be noted that the first fixing hole 7 and the second positioning hole are fixed by a bolt inserted between them, connecting the striking component 9 and the sliding component 5. The setting of multiple sets of first positioning holes can ensure that the striking component 9 can move on the sliding component 5 to facilitate the compaction of foil at different positions on the winding machine. The T-shaped design is intended to widen the force-bearing area of ​​the striking component 9. Firstly, the cooperation of the second fixing hole 13 with the second fixing hole 13 can only ensure that the striking component 9 does not move horizontally in the sliding groove 6, while the T-shaped design with a widened bottom can prevent its vertical movement. Secondly, during the process of the striking component 9 striking and compacting the foil, the striking rod 10 will bear a large amount of shear force, and the T-shaped widening design can increase the shear force bearing capacity. The crossbar 11 is fixedly connected to the striking rod 10.

[0034] It should be noted that, in order to avoid the lever slipping off during the push of the power lever 4 and to meet the requirements of shock absorption, the grip 16 is set to a rubber grip 16.

[0035] The working principle of this utility model is as follows: The operator fixes the striking rod 10 on the corresponding first fixing hole 7 of the sliding groove 6 according to the position of the foil hollow. The first fixing hole 7 and the second fixing hole 13 are riveted with bolts. Then the first telescopic rod 14 extends from the second telescopic rod 15 and pushes the power rod 4. The power rod 4 drives the sliding groove 6 to rotate along the rotating shaft 2 until the striking head 12 hits the foil hollow position.

[0036] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model.
