Description

Technical Field

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

[0002] A transformer is a device that uses the principle of electromagnetic induction to change alternating current voltage. During transformer manufacturing, the coils need to be pressed and fixed. Currently, when pressing wires, workers typically insert one end of a metal wire into a pressing device and then press the wire directly. However, this method has some problems: typical devices can only press one coil at a time, and the coil needs to be fixed during the pressing process, resulting in low work efficiency.

[0003] A wire pressing device for processing transformer coils is disclosed in the prior art patent application with publication number CN219286210U. The device includes a worktable and can press multiple coils simultaneously, thereby improving work efficiency.

[0004] However, in the existing technology, the wire pressing effect is not good, and the coils cannot be tightly bonded, which leads to a reduction in the manufacturing level of the transformer. Utility Model Content

[0005] The purpose of this invention is to provide a wire pressing device for transformer coil processing, which aims to solve the problem in the prior art that the wire pressing effect is poor, the coil cannot be tightly attached, and the process level of the transformer is reduced.

[0006] To achieve the above objectives, this utility model provides a wire pressing device for processing transformer coils, including a workbench and a wire pressing mechanism. The wire pressing mechanism includes a fixed frame, a cylinder, a mounting plate, and four pressing components. Each pressing component includes a pressing cylinder, a fixed cylinder, and a limiting post. The fixed frame is fixedly connected to the workbench and located above the workbench. The cylinder is fixedly connected to the fixed frame and located inside the fixed frame. The mounting plate is fixedly connected to the output end of the cylinder. The four pressing components are disposed on the mounting plate and the workbench. The pressing cylinder is fixedly connected to the mounting plate and located below the mounting plate. The fixed cylinder is fixedly connected to the workbench and located below the pressing cylinder. The limiting post is fixedly connected to the workbench and located inside the fixed cylinder.

[0007] The compaction assembly further includes a reset spring and a reset plate. The two ends of the reset spring are fixedly connected to the worktable and the reset plate, respectively, and are located inside the fixed cylinder. The limiting post is located inside the reset spring and passes through the reset plate.

[0008] The compaction assembly further includes two sliders and two grooves. The two grooves are respectively disposed at both ends of the fixed cylinder. The two sliders are respectively fixedly connected to both ends of the fixed cylinder. The two sliders are slidably connected to the fixed cylinder and are respectively located in the two grooves.

[0009] The wire pressing mechanism further includes two limiting components, which are disposed on the fixing frame and the mounting plate.

[0010] The limiting component includes a locking strip and a locking slot. The locking slot is disposed on the fixing frame. One end of the locking strip is fixedly connected to the mounting plate. The locking strip is slidably connected to the fixing frame and passes through the locking slot.

[0011] This utility model discloses a wire pressing device for processing transformer coils. When pressing the transformer coil, the coil is placed inside the fixed cylinder. At this time, the limiting post is located in the center hole of the coil. The cylinder is activated, and the cylinder drives the mounting plate and the pressing cylinder to be fixedly connected. The pressing cylinder presses down, and the limiting post enters into the pressing cylinder. The pressing cylinder compacts the coil, making the wires in the coil fit more tightly together, thereby improving the process level of the transformer. Attached Figure Description

[0020] This utility model provides a wire pressing device for transformer coil processing, including a workbench 101 and a wire pressing mechanism. The wire pressing mechanism includes two limiting components, a fixing frame 102, a cylinder 103, a mounting plate 104, and four compaction components. The compaction components include a pressing cylinder 105, a fixing cylinder 106, a limiting post 109, a return spring 107, a return plate 108, two sliders 110, and two sliding grooves 111. The limiting components include a locking strip 112 and a locking groove 113. This invention solves the problem in the prior art where the wire pressing effect is poor, the coil cannot be tightly fitted, and the process quality of the transformer is reduced. It can be understood that after the coil is compacted, the output end of the cylinder 103 is controlled to retract, and the mounting plate 104 and the pressing cylinder 105 move upward. At this time, the return spring 107 extends under its own elastic potential energy and pushes the coil out of the fixing cylinder 106, so that the operator can take out the coil, which increases the practicality of the device.

[0021] In this embodiment, the fixing frame 102 is fixedly connected to the workbench 101 and located above the workbench 101; the cylinder 103 is fixedly connected to the fixing frame 102 and located inside the fixing frame 102; the mounting plate 104 is fixedly connected to the output end of the cylinder 103; four compaction components are disposed on the mounting plate 104 and the workbench 101; the extrusion cylinder 105 is fixedly connected to the mounting plate 104 and located below the mounting plate 104; and the fixing cylinder 106 is fixedly connected to the workbench 101 and located below the extrusion cylinder 105. Below, the limiting post 109 is fixedly connected to the workbench 101 and located inside the fixed cylinder 106. When pressing the transformer coil, the coil is placed inside the fixed cylinder 106. At this time, the limiting post 109 is located inside the center hole of the coil. The cylinder 103 is activated, and the cylinder 103 drives the mounting plate 104 and the extrusion cylinder 105 to move downward. The extrusion cylinder 105 presses down, and the limiting post 109 enters the extrusion cylinder 105. The extrusion cylinder 105 compacts the coil, making the wires in the coil fit more tightly together, thereby improving the transformer's manufacturing process.

[0022] Furthermore, the two ends of the reset spring 107 are fixedly connected to the worktable 101 and the reset plate 108 respectively, and are located inside the fixed cylinder 106. The limiting post 109 is located inside the reset spring 107 and passes through the reset plate 108.

[0023] In this embodiment, when pressing the transformer coil, the coil is placed inside the fixed cylinder 106, and the coil is located on the reset plate 108. At this time, the limiting post 109 is located in the center hole of the coil. The cylinder 103 is activated, and the cylinder 103 drives the mounting plate 104 and the extrusion cylinder 105 to move downward. The extrusion cylinder 105 presses down, and the limiting post 109 enters the extrusion cylinder 105. The extrusion cylinder 105 compacts the coil. The reset spring 107 contracts under the pressure of the extrusion cylinder 105. The reset plate 108 moves downward, and the reset spring 107 contracts to its maximum extent. The extrusion cylinder 105 continues to press down until the coil is completely compacted. When the coil is completely compacted, the output end of the cylinder 103 is controlled to contract, and the mounting plate 104 and the extrusion cylinder 105 move upward. At this time, the reset spring 107 extends under the action of its own elastic potential energy and pushes the coil out of the fixed cylinder 106, so that the operator can take out the coil, which increases the practicality of the device.

[0024] Furthermore, the two slide grooves 111 are respectively disposed at both ends of the fixed cylinder 106, the two sliders 110 are respectively fixedly connected to both ends of the fixed cylinder 106, the two sliders 110 are slidably connected to the fixed cylinder 106, and are respectively located in the two slide grooves 111.

[0025] In this embodiment, during the extension and retraction of the reset spring 107, i.e., the up and down movement of the reset plate 108, the two sliders 110 slide within the two slide grooves 111 respectively. The two sliders 110 and the two slide grooves 111 play a limiting and guiding role for the extension and retraction of the reset spring 107 and the up and down movement of the reset plate 108, ensuring that the reset plate 108 maintains the correct movement trajectory during its up and down movement and will not be misaligned, thereby increasing the structural stability of the device.

[0026] Furthermore, the two limiting components are disposed on the fixing frame 102 and the mounting plate 104.

[0027] Furthermore, the slot 113 is disposed on the fixing frame 102, one end of the card strip 112 is fixedly connected to the mounting plate 104, the card strip 112 is slidably connected to the fixing frame 102, and passes through the slot 113.

[0028] In this embodiment, when the mounting plate 104 moves up and down, the two locking strips 112 slide up and down in the two locking slots 113 respectively, and the two locking strips 112 and the two locking slots 113 play a role in limiting and guiding the movement of the mounting plate 104.

[0029] When using this invention to compact the transformer coil, the coil is placed inside the fixing cylinder 106 and positioned on the reset plate 108. At this time, the limiting post 109 is located within the center hole of the coil. The cylinder 103 is activated, causing the mounting plate 104 and the extrusion cylinder 105 to move downwards. The extrusion cylinder 105 presses down, and the limiting post 109 enters the extrusion cylinder 105, compacting the coil. The reset spring 107 contracts under the pressure of the extrusion cylinder 105. The plate 108 moves downward, the return spring 107 contracts to its maximum extent, and the extrusion cylinder 105 continues to press down until the coil is completely compacted. After the coil is compacted, the output end of the cylinder 103 is controlled to contract, and the mounting plate 104 and the extrusion cylinder 105 move upward. At this time, the return spring 107 extends under its own elastic potential energy and pushes the coil out of the fixed cylinder 106 so that the operator can take out the coil. The above method makes the wires in the coil fit more tightly, thereby increasing the technological level of the transformer.

Those skilled in the art will understand that all or part of the processes for implementing the above embodiments, and equivalent variations made in accordance with the claims of this application, still fall within the scope of this application.
