Abstract
Description
Technical Field
[0001] This utility model relates to the field of heat shrink tubing shrinkage technology, and in particular to a heat shrink tubing shrinkage preparation device. Background Technology
[0002] Existing heat shrink tubing shrinking devices all use nozzles to spray air onto a heating plate to heat the air, and then spray the hot air evenly onto the heat shrink tubing to shrink and wrap the wire harness. Although this is convenient to operate and provides heat shrinking speed, it can only process a small number of wire harnesses at a time and cannot effectively utilize the heat shrinking time. For example, a Chinese patent discloses a heat shrink tubing shrinking device with application number CN202321246165.8. Although it can process heat shrink tubing by distributing heated air through a hollow distribution plate into multiple nozzles, and the multiple ring-shaped nozzles use hot air to heat and shrink the heat shrink tubing placed in the center, the heat shrinking is fast. The wider distribution of nozzles can heat and shrink longer heat shrink tubing. The device has a compact overall structure, is easy to operate, and shrinks quickly. However, it can only process a small number of heat shrink tubing at a time, and it cannot process another set of heat shrink tubing during the heat shrinking process, thus not making full use of the heat shrinking time and having limitations in use. Utility Model Content
[0003] The purpose of this utility model is to at least solve one of the technical problems existing in the prior art, and to provide a heat shrink tubing shrinkage preparation device. By opening multiple through holes in a copper plate, multiple heat shrink tubing can be processed at one time. The heating wire is wound in an S-shape around the copper tube in the wire groove, so that the entire copper plate is heated evenly and the heating efficiency is improved. Furthermore, two sets of heat shrink tubing fixtures can be used simultaneously. During the heating and processing of one set of heat shrink tubing fixtures, the heat shrink tubing and wire harness are installed on the other set of heat shrink tubing fixtures during the processing time. This alternating use method improves work efficiency.
[0004] This utility model also provides a heat shrink tubing shrinkage preparation device as described above, comprising: a copper plate, wherein a through hole is provided on the upper surface of the copper plate, a groove is provided on the lower surface of the copper plate, and a copper tube is fixedly connected to the lower surface of the copper plate;
[0005] A perforated bakelite board is fixedly connected to the lower surface of the copper plate. A wire-passing hole is provided on the upper surface of the perforated bakelite board. A second perforated bakelite board is fixedly connected to the lower surface of the first perforated bakelite board. A second wire-passing hole is provided on the upper surface of the second perforated bakelite board. The copper plate, the first perforated bakelite board, and the second perforated bakelite board constitute a heat shrink tubing fixture. Using these components, the heating wire can be wound in an S-shape around the copper tube in the wire groove, ensuring uniform heating of the entire copper plate and improving heating efficiency. Multiple sets of heat shrink tubing and wire harnesses can be processed simultaneously. Furthermore, no operator intervention is required during the heat shrinking process, allowing workers to install heat shrink tubing and wire harnesses on another heat shrink tubing fixture, thus improving processing efficiency.
[0006] According to the heat shrink tubing shrinkage preparation device of this utility model, a positioning hole is provided on the upper surface of the copper plate, and the through hole extends through the upper surface of the copper plate to the copper tube. A fixing component using screws can pass through the positioning hole to fix the copper plate, the perforated bakelite board one, and the perforated bakelite board two together.
[0007] According to the heat shrink tubing shrinkage preparation device of this utility model, the upper surface of the perforated bakelite board is provided with a positioning hole, and the lower surface of the perforated bakelite board is provided with a fixing hole. This allows the perforated bakelite board to be fixed through the positioning hole and the fixing hole.
[0008] According to the heat shrink tubing shrinkage preparation device of this utility model, the diameter of the first threading hole is smaller than that of the through hole, and the diameters of the first threading hole and the second threading hole are the same. This ensures that the heat shrink tubing will not fall out of the copper plate after being inserted into the through hole, and allows the wire to pass through the first and second threading holes to the bottom.
[0009] According to the heat shrink tubing shrinkage preparation device of this utility model, the upper surface of the perforated bakelite board 2 is provided with a positioning hole 3, and the lower surface of the perforated bakelite board 2 is provided with a fixing hole 1. The perforated bakelite board 2 can be fixed by the positioning hole 3 and the fixing hole 1.
[0010] According to the heat shrink tubing shrinkage preparation device of this utility model, a worktable is fixedly connected to the lower surface of the perforated bakelite board second, and the through hole is connected to the wire threading hole first during operation, allowing the wire to pass through the through hole and into the wire threading hole first.
[0011] According to the heat shrink tubing shrinkage preparation device of this utility model, the first threading hole is connected to the second threading hole during operation, and the first fixing hole is connected to the second fixing hole during operation. This allows the wire to pass through the first threading hole and into the second threading hole, and the perforated bakelite board 1 and the perforated bakelite board 2 are fixed together using screws or other fixing components through the first and second fixing holes.
[0012] According to the heat shrink tubing shrinkage preparation device of this utility model, the first positioning hole is connected to the second positioning hole during operation, and the second positioning hole is connected to the third positioning hole during operation. This allows the copper plate, the first perforated bakelite board, and the second perforated bakelite board to be fixedly installed together through the first positioning hole, the second positioning hole, and the third positioning hole.
[0013] Beneficial effects: Compared with the existing technology, this new heat shrink tubing shrinkage preparation device can process multiple heat shrink tubing at one time by opening multiple through holes in the copper plate. The heating wire is wound in an S-shape on the copper tube in the wire groove, which makes the entire copper plate heat up evenly and improves the heating efficiency. Furthermore, two sets of heat shrink tubing fixtures can be used at the same time. While one set of heat shrink tubing fixtures is heating and processing, the heat shrink tubing and wire harness are installed on the other set of heat shrink tubing fixtures. This alternating use method improves work efficiency. Attached Figure Description

[0021] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.
[0022] Reference Figure 1-4This utility model provides a heat shrink tubing shrinkage preparation device, which includes: a copper plate 1, a through hole 2 on the upper surface of the copper plate 1 extending through the upper surface of the copper plate 1 to a copper tube 8, a wire groove 7 on the lower surface of the copper plate 1, a copper tube 8 fixedly connected to the lower surface of the copper plate 1, a perforated bakelite board 4 fixedly connected to the lower surface of the copper plate 1, a wire hole 9 on the upper surface of the perforated bakelite board 4, a perforated bakelite board 5 fixedly connected to the lower surface of the perforated bakelite board 4, and a wire hole 11 on the upper surface of the perforated bakelite board 5. The copper plate 1, the perforated bakelite board 4, and the perforated bakelite board 5 together form a heat shrink tubing fixture.
[0023] Specifically, copper plate 1, perforated bakelite board 1 4, and perforated bakelite board 2 5 form a heat shrink tubing fixture. There are two heat shrink tubing fixtures in the device. Before use, the heating wire is arranged in the wire groove 7 of copper plate 1 and wound in an S-shape on copper tube 8. Then, copper plate 1 is placed on perforated bakelite board 1 4 and perforated bakelite board 2 5, which are fixed together and each has a thickness of 25 mm. Then, the heat shrink tubing is inserted into the through hole 2 on copper plate 1. The wire harness is then passed through the through hole 2, wire hole 1 9, and wire hole 2 11 until the bottom of perforated bakelite board 2 5. Then, the heating wire is activated to heat copper tube 8, causing the heat shrink tubing to shrink and wrap around the wire harness.
[0024] The lower surface of the perforated bakelite board 2 5 is fixedly connected to the workbench 6. The through hole 2 is connected to the wire hole 1 9 during operation. The wire hole 1 9 is connected to the wire hole 2 11 during operation. The diameter of the wire hole 1 9 is smaller than that of the through hole 2. The diameters of the wire hole 1 9 and the wire hole 2 11 are the same.
[0025] Specifically, the device is placed on the workbench 6 for easy operation. At the same time, the through hole 2, the wire hole 19 and the wire hole 21 are interconnected, so that the wire bundle can pass through the hole to the bottom of the perforated bakelite board 25. The diameter of the wire hole 19 is smaller than that of the through hole 2, so that the heat shrink tubing placed in the through hole 2 will not fall out of the copper plate 1 through the wire hole 19.
[0026] The upper surface of the copper plate 1 is provided with positioning hole 3, the upper surface of the perforated bakelite board 4 is provided with positioning hole 10, and the upper surface of the perforated bakelite board 5 is provided with positioning hole 12. Positioning hole 3 is connected to positioning hole 10 during operation, and positioning hole 10 is connected to positioning hole 12 during operation.
[0027] Specifically, positioning holes are provided on copper plate 1, perforated bakelite board 4 and perforated bakelite board 5, so that the fixing component can pass through the positioning holes to position and fix copper plate 1, perforated bakelite board 4 and perforated bakelite board 5 together, to prevent the through hole 2, wire hole 9 and wire hole 11 from being disconnected, which would prevent the wire harness from being inserted.
[0028] The lower surface of the perforated bakelite board 4 is provided with a fixing hole 2 14, and the lower surface of the perforated bakelite board 5 is provided with a fixing hole 13. The fixing hole 13 is connected to the fixing hole 2 14 during operation.
[0029] Specifically, the perforated bakelite board 14 and the perforated bakelite board 25 are respectively provided with fixing holes 214 and 13, so that when the two sets of perforated bakelite boards are connected to the copper plate 1, they are first fixed together by fixing components through the fixing holes, which facilitates the improvement of the accuracy of heat shrink tubing processing.
[0030] Working principle: Before use, two 25mm thick perforated bakelite boards, 4 and 5, are fixed together using fixing components through fixing holes 13 and 14. Then, the heating wire is arranged in the wire groove 7 of the copper plate 1 and wound in an S-shape around the copper tube 8. The copper plate 1 is then placed on the perforated bakelite board 4. The copper plate 1, perforated bakelite board 4, and perforated bakelite board 5 are positioned and fixed on the worktable using fixing components through positioning holes 3, 10, and 12. A set of heat shrink tubing fixtures is assembled on the 6th, and then the two assembled heat shrink tubing fixtures are connected on the same control panel. When processing is required, the heat shrink tubing is inserted into the through hole 2 on the copper plate 1, and then the wire harness is passed through the through hole 2, the wire hole 9, and the wire hole 11 until it reaches the bottom of the perforated bakelite board 5. The heating wire is activated to heat the copper tube 8, causing the heat shrink tubing to shrink and wrap the wire harness. During the heating process, it can be moved to another set of heat shrink tubing fixtures to install the heat shrink tubing and wire harness, making full use of the processing time and improving the work efficiency.
[0031] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
