Hydraulic tyre vulcanizing machine in column type strap clamp locked mould mode, and method for adjusting mould

Abstract

The invention discloses a hydraulic tire vulcanizing machine with column clamping plate lock mode and its mold adjustment method, which comprises a base, a liftable upper beam, a column for guiding mold opening and closing and bearing mold clamping force, an oil cylinder for opening and closing molds, Pressurized oil cylinder, lower supporting plate, upper and lower heating plates for mounting and connecting the upper and lower molds of the tire mold, and clamping mold clamping device. Through the loose / clip fit between the clamping plate and the annular groove of the column, a closed force system of the clamping force is formed, and the clamping force is applied, and components such as the frame, the upper and lower cylinders, and the locking ring can be omitted, so that the structure of the vulcanizing machine is simple. Reliable and easy to maintain. Due to the adoption of a unique mold clamping system, mold adjustment method, pressurized oil cylinder installation method, and multi-column guiding structure, the overall structure of the hydraulic tire curing machine can be greatly simplified, the height and weight of the whole machine are greatly reduced, and the amount of maintenance is greatly reduced. Reduced, thereby improving the precision of the hydraulic tire vulcanizing machine and greatly reducing the manufacturing cost.

Description

technical field [0001] The invention relates to a tire vulcanizing equipment, in particular to a hydraulic tire vulcanizing machine in a column clamping plate lock mode and a mold adjustment method thereof. Background technique [0002] Tire curing presses are usually divided into two categories: mechanical and hydraulic. [0003] The mechanical tire vulcanizing machine generally adopts a four-bar linkage mechanism. It uses the four-bar linkage mechanism to perform mechanical movement to realize the tightness of the upper and lower molds. After pressurization and heating, the tire is vulcanized in the mold. Its disadvantages are as follows: The structure is complex, such as the beam base structure is bulky, and includes a crank gear transmission mechanism, etc.; the second is poor rigidity, such as the beam and the four-link are easily deformed; the third is the centering accuracy is low; the fourth is that the mold life is long due to the deformation of the beam Affected; ...

[0003] The mechanical tire vulcanizing machine generally adopts a four-bar linkage mechanism. It uses the four-bar linkage mechanism to perform mechanical movement to realize the tightness of the upper and lower molds. After pressurization and heating, the tire is vulcanized in the mold. Its disadvantages are as follows: The structure is complex, such as the beam base structure is bulky, and includes a crank gear transmission mechanism, etc.; the second is poor rigidity, such as the beam and the four-link are easily deformed; the third is the centering accuracy is low; the fourth is that the mold life is long due to the deformation of the beam Affected; Fifth, the long time of mold opening and closing affects the efficiency; Sixth, the maintenance of the mechanical structure is large

Although such a structural form can save parts such as the frame and reduce the weight of the whole machine, due to the addition of parts such as the upper and lower cylinders and lock rings, the mold is surrounded by the upper and lower cylinders, resulting in difficulty in connection and inconvenient maintenance.

Secondly, the mold adjustment mechanism is realized by the mold adjustment cylinder installed in the abdominal cavity of the base. The mold adjustment cylinder must directly bear the mold clamping force and is connected with the pressurized cylinder, which makes the structure of the two cylinders complex and large, difficult to maintain, and also makes the mold Multiple cylinders cannot be installed, so that the pressure on the mold cannot be more uniform

Third, due to the form of a single column for mold opening and closing, the column is placed behind the middle of the vulcanizing machine, resulting in uneven force on the column, poor positioning and guidance, and unstable operation, which affects the accuracy of the whole machine, especially the repeatability
