Description

Technical Field

[0001] This utility model relates to the field of cold shrink tubing processing technology, and in particular to a cold shrink tubing processing expansion device. Background Technology

[0002] As a critical insulating and protective component in fields such as power, communications, and automobiles, the expansion process during the manufacturing of cold shrink tubing directly determines the final protective performance and ease of installation. In the mass production of cold shrink tubing, the blank material must be precisely expanded to a preset size using expansion equipment, and then a support frame is installed to maintain the expanded state. This facilitates quick insertion into the workpiece to be protected during subsequent on-site construction. After removing the frame, the cold shrink tubing can shrink and fit the workpiece on its own elasticity to achieve an insulating seal.

[0003] However, in the early stages of cold shrink tubing processing technology and in some small workshop-style production scenarios, there was still a reliance on manual operation using tools (such as manual expander pliers, simple conical molds, etc.) to expand cold shrink tubing. However, this method is limited by the subjectivity of manual operation and the simplicity of the tools, resulting in many unavoidable defects that severely restrict the processing quality and production efficiency of cold shrink tubing. Secondly, when expanding manually using expander pliers or conical molds, the operator relies entirely on their sense of touch to control the magnitude and direction of the force applied, which cannot guarantee that the cold shrink tubing is subjected to uniform force in the circumference. Utility Model Content

The outer surface of the 13 is provided with a through hole 15, and the inner surface of the through hole 15 is slidably connected with a slide rod 16. The outer surface of the fixed plate 3 is provided with a limit groove 17, and the inner surface of the limit groove 17 is slidably connected with the connecting seat 13 to limit the movement of the connecting seat 13. The outer surface of the threaded rod 6 is rotatably connected to the fixed frame 4 through a bearing, and the outer surface of the threaded rod 6 is rotatably connected to the fixed plate 3. The outer surface of the limit block 7 is rotatably connected to the fixed plate 3 to limit the rotation of the threaded rod 6. There are four quarter-pins 14 arranged in a circular array to facilitate the uniform expansion of the cold shrink tube. The inner surface of the limit groove 17 is fixedly connected to the slide rod 16 to guide the movement of the connecting seat 13. A support frame compartment is provided on the left side of the partition 2, and a cold shrink tube compartment is provided on the right side of the partition 2 to facilitate the placement of materials.

[0028] Those skilled in the art should connect all electrical components in this case to their compatible external power supply via wires, and should select a suitable controller according to the actual situation to meet the control requirements.

The detailed connection methods are well-known in the art. The following mainly introduces the working principle and process, and will not describe the electrical control further.

[0029] Working principle: In use, the cold shrink tubing in the cold shrink tubing compartment is fitted onto the quarter pin 14. Then, as needed, the motor 5 is started, driving the threaded rod 6 to rotate under the limiting action of the limiting block 7. This causes the slide 8 to move forward along the axis of the threaded rod 6. Under the hinge action of the fixed seat 9, fixed column 10, long strip plate 11, connecting column 12 and connecting seat 13, the four quarter pins 14 are driven to expand outward synchronously and evenly, thus expanding the cold shrink tubing to different sizes as needed, thereby improving the applicability of the equipment. Then, the support frame inside the support frame compartment is passed through the expanded cold shrink tubing. The cold shrink tubing fitted onto the quarter pin 14 and the support frame are then pulled out together. Under the action of the rebound force of the cold shrink tubing, the cold shrink tubing will directly wrap around the support frame to complete the installation.
