Description

Technical Field

[0001] This utility model relates to the field of tire vulcanizing machine technology, and in particular to a tire vulcanizing machine servo system. Background Technology

[0002] Since the 1950s, the vulcanization of automobile tires has been promoted and applied using bladder-type vulcanizing machines. For tires with an inner diameter of less than 65 mm, namely all passenger car tires and light and medium-sized truck tires, the vulcanization of tires is basically carried out using dual-mold vulcanizing machines. For tires with an inner diameter of more than 65 mm, single-mold vulcanizing machines or vulcanizing tanks are used. The first commonly used dual-mold vulcanizing machine is the mechanical vulcanizing machine, which adopts a crank gear-connecting rod (or four-bar linkage) structure. The mechanism is simple in principle. The clamping force is applied at the moment of mold closing. A large clamping force can be obtained with a small motor power. After the mold is closed, the motor no longer works, but the clamping force can be maintained until the mold is reopened. Although the mechanical vulcanizing machines used in the world today are manufactured by different companies and have different specifications and models, and have been continuously improved over the years, their basic structure is the same and has not changed.

[0003] However, the servo motor of the existing tire vulcanizing machine is separate from the vulcanizing machine, which occupies a large area and is heavy. At the same time, there is a matching process when selecting the driver and the servo motor, which is troublesome to operate. To solve the above problems, a servo system for tire vulcanizing machines is proposed. Utility Model Content

[0004] To address the aforementioned technical problems, this utility model provides a servo system for a tire vulcanizing machine, characterized by comprising a machine body, a left motor pump group and a right motor pump group mounted on the machine body, an internal valve group mounted on the machine body, a return oil filter unit located next to the internal valve group, a plate-type water cooling unit located behind the return oil filter unit, a cleaning window located at the rear of the machine body, a level gauge located next to the cleaning window, an electrical control cabinet located on the side of the machine body, and an oil drain port located at the bottom of the machine body.

[0005] The machine body contains a hydraulic oil tank. One end of the left motor pump unit extends into the hydraulic oil tank, and the other end is connected to the station valve group through a pipe. The part extending into the hydraulic oil tank has an oil suction filter. The left motor pump unit contains an internal gear pump and a servo motor controlled by a controller, which are connected by a coupling with a bell cover.

[0006] The right motor pump unit has the same structure as the left motor pump unit. One end extends into the hydraulic oil tank, and the other end is connected to the valve group in the station through a pipe. The part that extends into the hydraulic oil tank has an oil suction filter.

[0007] Furthermore, the valve group in the station includes two connection ports, each with an SAE ball valve, and each connection port is equipped with a pressure sensor for pressure measurement, a shock-resistant pressure gauge, a pressure measuring hose, a pressure measuring connector, and an overflow valve.

[0008] Furthermore, the return oil filtration section includes a return oil filter and two outlets with SAE ball valves. The return oil filter is connected to the hydraulic oil tank, and there are pressure test connectors on the pipes connecting the return oil filter and the two outlets.

[0009] Furthermore, the plate-type water-cooled section includes a plate-type water cooler, a pneumatic water valve, a water filter, a pneumatic reversing valve, and a silencer. The plate-type water cooler is located on one side of the machine body and is installed on the pipeline connecting the left motor pump group, the right motor pump group, and the station valve group. A cartridge solenoid valve is installed on the pipeline. A pneumatic water valve and a water filter are installed on the water inlet of the plate-type water cooler. A pneumatic reversing valve and a silencer are installed on the pneumatic water valve.

[0010] Furthermore, there is heat insulation cotton between the machine body and the electrical control cabinet, an oil drain port is located at the bottom of the hydraulic oil tank, and the hydraulic oil tank contains an oil drain ball valve, a liquid level and temperature gauge, an air filter, and a liquid level and temperature sensor.

[0011] The beneficial effects of this utility model are:

[0012] This invention utilizes servo motors controlled by a controller to drive a coupling with a bell and an internal gear pump in both the left and right motor pump units. Hydraulic oil is drawn from the hydraulic tank within the machine body and connected to external pipelines through two outlets of the station's valve group, achieving tire vulcanization. During operation, the hydraulic tank within the machine body is replaced via a return oil filter, facilitating operation. A plate-type water-cooling unit cools the pipelines connecting the left and right motor pump units to the station's valve group, increasing service life and improving efficiency. The servo motors are fixed to the vulcanizing machine body, resulting in a compact structure with a small footprint. The elimination of the matching process simplifies operation. Direct connection between the servo motor and controller saves on cables and simplifies hydraulic station wiring, eliminating the need for a control cabinet or reducing its size.
