Description

A pressurizing device in tire repair vulcanization process

technical field

The utility model relates to a pressurizing device in the vulcanization process of repairing tires.

Background technique

In the rubber vulcanization process, the vulcanization pressure is one of the three elements in the vulcanization process. On the one hand, the pressure can make the vulcanized product fill the entire mold cavity and make the pattern full; more importantly, it can increase the crosslinking density of the rubber, so that various physical The performance meets the requirements. In the past, only the method of sand compaction was used in the vulcanization of repaired rubber in repairing tires, and the pressure cannot be guaranteed to always be one of the important factors affecting the service life of the product.

Contents of the invention

The purpose of this utility model is to provide a pressurizing device in the vulcanization process of repairing tires, which solves the problems of insufficient vulcanization pressure of tire repairing rubber and poor physical properties of the rubber surface of repairing tires.

The purpose of this utility model can be achieved through the following schemes: including the base, the base is provided with a jack group, the jack group is composed of 1-3 jacks, and a pressure rod is arranged above the jack group, and the two ends of the pressure rod are respectively Connect with the lugs on both sides of the base through connecting rods.

The utility model has the characteristics of simple structure and convenient use. With this device, the vulcanization pressure is increased from 90Kg/cm ² to 245Kg/cm ² , and various physical and mechanical properties are improved. Among them, the main properties are: rubber and carcass The peeling strength is increased by 20%, and the range of repairing the breach is increased from φ15cm to φ35cm.

Description of drawings:

Fig. 1, the structural representation of the utility model

Detailed ways:

As can be seen from Fig. 1, the utility model comprises base 1, base 1 is provided with jack group 2, and described jack group 2 is made up of 1-3 jacks, is provided with pressure bar 3 on the top of jack group 2, and pressure bar 3 Both ends are respectively connected with lugs 5 on both sides of the base through connecting rods 4 .

The working principle of the utility model is: cover the rubber surface that needs to be pressurized with a layer of iron plate that is slightly larger than the repaired surface, place it between the pressure rod and the jack group, start the jack, and under the action of the pressure rod and the jack It can effectively pressurize the rubber.

Claims (1)

1, the pressue device in a kind of full capping sulfuration process, it is characterized in that comprising that base (1), base (1) are provided with jack group (2), described jack group (2) is made up of 1-3 jack, be provided with depression bar (3) in the top of jack group (2), the two ends of depression bar (3) are connected with the lug (5) of base both sides by connecting rod (4) respectively.
