Description

Technical Field

[0001] The utility model is applicable to the technical field of inner tube vulcanizers, in particular to a four-column inner tube vulcanizer. Background Art

[0002] At present, the inner tube is commonly known as the inner tube, which refers to an annular rubber and plastic elastic tube with a tire air nozzle used to maintain the internal pressure of the tire. The vulcanizer is a machine for vulcanizing various rubber and plastic systems.

[0003] However, when the inner tube vulcanizer used today performs high-temperature and high-pressure treatment on inner tubes made of rubber and plastic, it is necessary to place the inner tube to be treated on the surface of the vulcanization mold in advance to ensure that the heated heat can directly act on the inner tube to achieve vulcanization treatment. When placing the inner tube, it is limited by the non-adjustability of the mold itself, which results in the placement groove inside the mold being unable to adjust the applicability when inner tubes of different sizes are placed on the mold surface, which can easily cause the inner tube to shake arbitrarily when it is pressed down, affecting the vulcanization quality. Therefore, we propose a four-column inner tube vulcanizer. Utility Model Content

[0004] The main purpose of the utility model is to provide a four-post inner tube vulcanizing machine, which can effectively solve the problems in the background technology.

[0005] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0007] The upper mold body and the lower mold body are fixedly installed on the middle end surfaces of the upper mounting table and the lower mounting table respectively, the upper mold body is provided with a mounting groove inside, and a fixing plate is fixedly installed on the outside of the mounting groove, each of the fixing plates is rotatably installed with a rotating screw through a bearing inside, and the number of the rotating screws is several groups, and a transmission sleeve is movably sleeved on the outer surface of each rotating screw, and connecting rods are fixedly installed on the outer end surfaces of each transmission sleeve, and the connecting rods are slidably installed inside the fixing plate, and an arc-opening plate is fixedly installed between the ends of each two groups of connecting rods away from the transmission sleeve;

[0008] The top end surface of each rotating screw rod side is sleeved with a follower bevel gear, the middle end surface of the bottom of the lower mounting platform is fixedly mounted with a servo motor, the side of the servo motor transmission shaft is fixedly sleeved with a transmission bevel gear through a coupling, and the transmission bevel gear and the follower bevel gear are meshed with each other on their outer sides.

[0009] By adopting the above technical scheme, the position of the expansion arc plate inside the placement groove is adjusted under the meshing transmission action of the transmission bevel gear and the follower bevel gear, and under the rotation transmission action of the rotating screw on the transmission sleeve, so that the expansion arc plate can be fitted against the outer wall of the inner tube to be vulcanized located inside the placement groove, ensuring that the inner tube will not move arbitrarily inside the lower mounting table and affect the vulcanization quality of heating and pressurization.

[0010] As an optional solution of the technical solution of the present application, guide columns are vertically fixedly installed on the four corner surfaces of the top of the console, and the lower mounting platform is fixedly sleeved on the outside of the guide columns, and the upper mounting platform is slidably sleeved on the outside of the guide columns, and hydraulic push cylinders are vertically fixedly installed on the two side surfaces of the top of the lower mounting platform, and the top surface of the hydraulic push cylinder piston rod is fixedly connected to the bottom surface of the upper mounting platform.

[0011] As an optional solution of the technical solution of the present application, limiting grooves are provided inside both ends of the side edges of each of the fixing plates, and the connecting rods penetrate through and are slidably inserted into the limiting grooves.

[0012] By adopting the above technical solution, the transmission rationality of the entire device is ensured by the guiding and limiting effect of the limiting groove on the connecting rod.

[0013] As an optional solution of the technical solution of the present application, a placement groove is opened inside the lower mold body, and the expansion arc plate is movably installed inside the placement groove, and an anti-slip friction pad is fixedly bonded to the outer surface of each expansion arc plate.

[0014] By adopting the above technical solution, the inner tube to be vulcanized can be placed for load-bearing treatment through the structural effect of the placement groove.

[0015] Compared with the prior art, the utility model has the following beneficial effects:

[0016] 1. A four-column inner tube vulcanizer according to the technical solution of the present application, through the meshing transmission action of the transmission bevel gear and the follower bevel gear, when the servo motor is running and drives the transmission bevel gear to rotate synchronously inside the installation groove, it can synchronously drive multiple groups of rotating screws to rotate synchronously, and then, combined with the rotation transmission action of the rotating screw on the transmission sleeve, the multiple groups of transmission sleeves can be synchronously moved toward or relative to each other inside the installation groove, and then, under the transmission action of the connecting rod, a corresponding outward push-pull force is provided to the expansion arc plate, the position of the expansion arc plate inside the placement groove is adjusted, and then the expansion arc plate can be fitted and moved from the outer wall of the inner tube to be vulcanized located inside the placement groove, to ensure that the inner tube will not move arbitrarily inside the lower mounting table and affect the vulcanization quality under heating and pressurization.
