Automotive tire repair simple equipment and use
The price of formal equipment for repairing automobile tires is over 6,000 yuan, plus ancillary tools, for a total of 7,000 yuan. In order to save money, it is entirely possible to make self-made and simple tire repair equipment. The cost is only about 1,500 yuan. It replaces coal heating with an electric heating mold of a high-temperature resistant rubber heating plate; an automatic temperature controller replaces the pressure gauge. High degree of automation, saving labor. Its main composition plan is: (1) rubber deformation heating plate, built-in electric thermocouple. (2) Externally heated mold with built-in thermocouple. The molds are made according to the shape of the tire and are divided into 3 pieces. (3) The fixing frame is made of 5 cm 5 cm angle iron or channel steel welded with a plurality of fixing holes for fixing the heating mold. (4) Two temperature controllers are connected to the thermocouple to achieve automatic temperature control. (5) The wheel and lock ring are the same size as the tire. In the above composition scheme, the rubber heating plate can be made by itself or can be purchased by the auto parts department; the external heating mold is generally self-made; the fixing frame is self-manufactured; the corresponding roulette wheel can be used for the spare wheel of the car; the temperature control device and the thermocouple are required to reach the electronic component. Store purchase. Since self-made parts are simple and easy to manufacture, they will not be described here. The operating procedure is: after the tire is repaired, the corresponding tire heating plate is fixed on the damaged surface of the inner surface of the tire and spreads. Then, the inner tube and the lining tape are installed according to the conventional method, and the heater tab wire and the thermocouple wire are passed out together through the valve hole, and then the wheel disk and the lock ring are put on. Then fix the heating mold with a fixing bracket on the damaged part outside the tire. The inner tube is then inflated at a pressure of 60% to 70% of the working pressure. Pay attention to the pressure of the mold when inflated to prevent the mold from deforming. After the operation is complete, the energization heating can begin. The rubber inner heating sheet needs to be heated for 3.5-4.5 hours, and the outer heating mold needs 2.5-3.5 hours. The temperature can be adjusted and controlled by the thermocouple associated with the thermocouple. The temperature of the thermocouple and the temperature controller should be matched. Through practical proof, the repair equipment works well.
