Special tool for replacing tire capsule chuck

Abstract

The utility model relates to a special tool for replacing a tire bladder chuck, and belongs to the field of tire vulcanizing devices. A disc body is arranged, a circular counter bore is machined in the middle of the disc body, four square-column-shaped connecting rods are fixed to the periphery of the disc body at equal intervals, and heat insulation handles are fixed to the ends of the connecting rods. According to the utility model, the counter bore of the disc body is directly sleeved into the cylinder in the center of the tire capsule chuck, and the fixing wire on the tire capsule chuck is clamped and rotated, so that the mounting and dismounting time is greatly shortened, and meanwhile, the potential safety hazards such as scalding are avoided.

Description

Technical Field

[0001] The utility model relates to the field of tire vulcanization devices, in particular to a special tool for replacing a tire bladder chuck. Background Art

[0002] As we all know, tires are the main consumables of current wheeled transportation vehicles, and their safety performance and functions are subject to relatively strict requirements, which directly affect the life safety of drivers and passengers.

[0003] The tire manufacturing process is divided into mixing, semi-finished product production, molding, vulcanization, inspection and other steps. Among them, the vulcanization step is the key step that affects the performance of the tire. It is the process of rubber chemical reaction and the transformation from raw rubber to finished products. The main functional properties of rubber, such as strength and elasticity, can be realized. The key to vulcanization lies in the control of temperature, time and pressure in the process. The vulcanization capsule is a key auxiliary material in the vulcanization process. Steam medium is filled into the capsule, and heat is introduced into the rubber of the tire through the capsule, and pressure is provided to the tire through the expansion of the capsule. The vulcanization capsule is also a rubber product. Due to long-term high temperature and stretching conditions, it is damaged by thermal oxidation aging, so it is a consumable product and needs to be replaced after a period of use. Due to the high temperature conditions, there are certain dangers and difficulties when replacing it using traditional tools. Summary of the invention

[0004] In order to overcome the deficiencies of the prior art, the utility model provides a special tool for replacing a tire bladder chuck, which greatly increases work efficiency and ensures work safety.

[0005] The technical solution adopted by the utility model to solve the technical problem is: a special tool for replacing a tire bladder chuck, which is provided with a disc body, and is characterized in that a circular countersunk hole is processed in the middle of the disc body, four square columnar connecting rods are fixed at equal intervals on the periphery of the disc body, and heat-insulating handles are fixed at the ends of the connecting rods.

[0006] The beneficial effect of the utility model is that the countersunk hole of the disc body is directly inserted into the cylinder at the center of the tire bladder chuck, and the fixing wire on the tire bladder chuck is clamped and rotated, which is fast and convenient, greatly reducing the time for installation and disassembly, and also avoiding safety hazards such as burns.

[0010] In the figure, 1. countersunk hole, 2. disc body, 3. chuck fixing screw to lock in place, 4. connecting rod, 5. heat-insulating handle. DETAILED DESCRIPTION

[0011] In the figure, the utility model is provided with a disc body 2, a circular countersunk hole 1 is processed in the middle of the disc body 2, the diameter of the countersunk hole 1 is slightly larger than the cylinder in the middle of the tire capsule chuck, four square cylindrical connecting rods 4 are fixed at equal intervals on the outer periphery of the disc body 2, the position where the outer side of the connecting rod 4 contacts the disc body 2 is the clamping position 3 of the chuck fixing wire, and a heat-insulating handle 5 is fixed at the end of the connecting rod 4.

[0012] When the capsule chuck needs to be disassembled, align the countersunk hole 1 of the disc body 2 with the cylinder in the center of the tire capsule chuck and insert it, slightly turn the heat-insulating handle 5, clamp the fixing wire on the tire capsule chuck on the chuck fixing wire clamping position 3, and install (disassemble) the tire capsule chuck by rotating clockwise (counterclockwise).
