Description

Technical Field

[0001] The utility model belongs to the field of heat shrinkage processing, and particularly relates to a fixing device for shaping and processing heat shrinkable tubes. Background Art

[0002] As a conductive material, copper bars are widely used in the power system. At the same time, using heat shrinkable tubes on copper bars can provide additional insulation protection, playing a role in preventing electric leakage and waterproof sealing. Moreover, the heating and shrinking characteristics of heat shrinkable tubes can tightly wrap around copper bars, enhancing the durability and safety of copper bars. The copper bars in this device are provided with holes at both ends and in the middle positions, and the heat shrinkable tubes are wrapped around the copper bar segments without holes in sections, located between adjacent holes.

[0003] During the use of heat shrinkable tubes, there is usually a soft-hard transition zone. In the stage where the heat shrinkable tube starts to shrink but has not completely shrunk, the soft-hard transition zone plays a buffering role to avoid uneven material deformation, and can enable the heat shrinkable tube to better adapt to the shape and size of the copper bar during the shrinking process, ensuring a tight fit after shrinking.

[0004] After the heat shrinkable tube is heat-shrunk, the length of the heat shrinkable tube will change. When in use, the heat shrinkable tube should not be stretched to adapt to the size. Instead, the required precise length should be calculated based on the length change rate of the heat shrinkable tube to ensure that the size of the heat shrinkable tube after heat shrinking is within an acceptable error range.

[0005] According to the applicant's search, an authorized patent with the publication number CN207490279U mentions a wire harness heat shrinkable tube fixture, including a bottom plate; one end of the bottom plate is provided with a wire harness heat shrinkable tube wiring terminal limiting component, and the other end of the bottom plate is provided with a fixing component for fixing the end of the wire harness heat shrinkable tube wire; the limiting component includes two parallel limiting plates, and a limiting groove for accommodating the wire harness heat shrinkable tube wiring terminal is formed between the two limiting plates. Multiple first channels for the wire harness heat shrinkable tube wire to pass through are provided on the limiting plate close to the fixing component.

[0006] In the prior art represented by the above patent, there are at least the following problems: Both ends of the wire harness heat shrinkable tube are fixed on the wiring terminals, and the fixture fixes the whole wire harness heat shrinkable tube through the limiting plate and the positioning column, which will interfere with the external shape of the wire harness heat shrinkable tube. If the dried wire harness heat shrinkable tube needs to be adjusted, it is easy to cause damage. Summary of the Utility Model

[0007] The utility model provides a technical solution for solving the problems that the limiting structure interferes with the external shape of the heat shrinkable tube during the drying process, and it is easy to cause damage and dimensional deviation to the heat shrinkable tube when the whole heat shrinkable tube is heat-shrunk and then cut and adjusted.

[0008] To achieve the above object, the utility model is realized through the following technical solutions:

[0009] A fixing device for shaping and processing heat shrinkable tubes, comprising: a base, provided with a plurality of mounting grooves; a plurality of copper bars, clamped in the mounting grooves; a limiting structure, welded in the mounting grooves for restricting the movement of the copper bars; and a plurality of grooves, provided on the base.

[0010] The heat shrinkable tube is cut according to the size of the copper bar. The cut heat shrinkable tube is sleeved on the copper bar, and then the copper bar with the sleeved heat shrinkable tube is clamped and fixed in the mounting groove. The displacement of the copper bar in the mounting groove is restricted by the limiting structure, and the groove is used to prevent the base from contacting the heat shrinkable tube. It can effectively prevent the heat shrinkable tube from deforming or being damaged due to external factors.

[0011] Further, the copper bar includes a first mounting portion, a second mounting portion, a third mounting portion, a fourth mounting portion and a fifth mounting portion. There are bending parts on the copper bar. There is a bending part extending downward in the horizontal direction between the second mounting portion and the third mounting portion. There is a bending part extending upward in the horizontal direction to be flush with the first mounting portion and the second mounting portion between the third mounting portion and the fourth mounting portion. There is a bending part extending downward in the horizontal direction between the fourth mounting portion and the fifth mounting portion. The mounting grooves include a first mounting groove, a second mounting groove, a third mounting groove, a fourth mounting groove and a fifth mounting groove, and are respectively clamped corresponding to the first mounting portion, the second mounting portion, the third mounting portion, the fourth mounting portion and the fifth mounting portion.

[0012] The bending angles and the overall bending shape of the copper bar are required by the design. The positions where the copper bar is clamped with the mounting groove are the mounting portions. The base is provided with different raised heights according to the height of the clamping positions of the mounting portions. Ensure the stability of the copper bar clamped and fixed on the base.

[0013] Further, the limiting structure includes: a plurality of limiting blocks, arranged in the mounting grooves. The limiting blocks are equally spaced in the mounting grooves, so that the copper bar is clamped in the mounting grooves through the limiting blocks. The length of the limiting block is the same as the width of the mounting groove where the limiting block is located; a plurality of limiting points, arranged in the second mounting groove, the third mounting groove and the fourth mounting groove. The limiting points are arranged in the middle of the horizontal projection plane in the second mounting groove and the fourth mounting groove, and the limiting points are arranged on the side in the third mounting groove.

[0014] The copper bar is clamped and fixed between two adjacent limiting blocks on the same mounting groove. The limiting points are used to further restrict the displacement of the copper bar in the mounting groove, effectively avoiding the displacement or overlap of the copper bar with the heat shrinkable tube on the mounting groove, which affects the drying effect.

[0015] Further, fixing holes corresponding to the limiting points are formed in the part of the copper bar that is clamped with the installation groove.

[0016] The fixing holes and the limiting points further limit the displacement of the copper bar on the installation groove.

[0017] Further, a rubber ring is sleeved on the part of the copper bar that is not clamped with the installation groove.

[0018] The rubber ring is used to prevent the heat shrinkable tube from falling off or stacking on the copper bar, and increases the friction between the heat shrinkable tube and the copper bar.

[0019] Further, the groove includes a first groove, a second groove, a third groove and a fourth groove. The distances between the first groove, the second groove, the third groove and the fourth groove are not equal, and rectangular holes are respectively formed in the first groove, the second groove, the third groove and the fourth groove.

[0020] The rectangular holes formed in the groove facilitate the heat shrinkable tube sleeved on the copper bar to be heated more evenly during the heating process. Description of the Drawings
