Description

Technical Field

[0001] This utility model belongs to the field of rubber mold tooling technology, and specifically relates to a rubber cloth molding vulcanization curved surface stretching and shaping device. Background Technology

[0002] Large marine rubber sheeting, due to its large size, is formed by splicing single strips of rubber sheet. Some corner sections have curved surfaces, requiring curved vulcanization. After compression molding, the spliced ​​areas shrink due to heat vulcanization, resulting in shrinkage and wrinkles, affecting the shape and dimensional accuracy of the rubber sheet. Therefore, after curved splicing and compression molding, cold setting is necessary to stabilize the dimensions. Cold setting typically uses cold pressing equipment for dimensional stabilization. Conventional cold pressing requires specialized curved surface cold pressing equipment, which occupies a large area, only applies pressure, and results in significant shrinkage of the product after setting, poor setting effect, and a complex setting process that cannot be used for continuous production, where splicing and vulcanization are performed simultaneously with cold setting. Summary of the Invention

[0003] The purpose of this invention is to overcome the above-mentioned defects and provide a rubber cloth molding vulcanization curved surface stretching and shaping device, which has the advantages of simple operation, high shaping efficiency and good shaping effect.

[0004] The purpose of this utility model is achieved through the following technical solution: a rubber cloth molding vulcanization curved surface stretching and shaping device, characterized in that: it includes an operating table, adjustable supports, a manual pressure clamp, clamping pliers, and a winding device. The manual pressure clamp is fixed at one end of the operating table, and clamping pliers are placed on the operating table opposite to the manual pressure clamp. The winding device is fixed on the operating table outside the clamping pliers. A fixed roller is installed on the operating table between the winding device and the clamping pliers. One end of a steel wire rope is connected to the winding device, and the other end passes through the roller and connects to the clamping pliers. Several adjustable supports are installed at intervals on the operating table between the manual pressure clamp and the clamping pliers.

[0005] The lifting and adjusting supports are arranged at intervals, and the surfaces of several lifting and adjusting supports are arranged to form a curved surface.

[0006] The beneficial effects of this utility model are:

[0007] 1. The adjustable support spacing is arranged with a rounded surface. The rubber cloth is placed on the rounded surface, which can be stretched into different shapes of curves. It is easy to operate, has a wide range of applications, and has high dimensional stability.

[0008] 2. After curve stretching and shaping, the flatness of the rubber cloth is improved, the wrinkles on the surface of the rubber cloth are eliminated, and the dimensional stability of the rubber cloth is high.

[0009] 3. The electric winding device is used to pull and stretch the rubber cloth, which has high molding efficiency, can be continuously produced, and improves production efficiency. Attached Figure Description

[0014] Example: As shown in the figure, a rubber fabric molding and vulcanization curved surface stretching and shaping device is applicable to the stretching and shaping of all rubber fabric curved surfaces after molding and vulcanization to ensure the stability of the rubber fabric's dimensions and curve shape. It includes an operating platform 9, adjustable supports 2, manual pressure clamps 3, clamping pliers 5, and a winding device 8. The operating platform 9 is mounted on a supporting square steel bracket 10. The manual pressure clamp 3 is fixed to one end of the operating platform 9. The clamping pliers 5 are placed on the operating platform 9 opposite to the manual pressure clamp 3. The winding device 8 is fixed to the operating platform 9 outside the clamping pliers 5. A fixed roller 6 is installed on the operating platform 9 between the winding device 8 and the clamping pliers 5. One end of a steel wire rope 7 is connected to the winding device 8, and the other end passes through the roller 6 and is connected to the clamping pliers 5. Several adjustable supports 2 are installed at intervals on the operating platform 9, located between the manual pressure clamp 3 and the clamping pliers 5. The adjustable supports 2 are arranged at intervals, and their surfaces are arranged in an arc shape.

[0015] Working principle:

[0016] After the curved molding and vulcanization of the rubber cloth 1, one end of the splice joint 11 is placed under the pressure plate 4 of the manual pressure clamp 3 for clamping. For different curves, the surfaces of several spaced adjustable supports 2 are adjusted to be arc-shaped or other curved surfaces. The curved rubber cloth 1 is laid flat on the arc-shaped surface of the adjustable support 2. The other end of the splice joint 11 of the curved rubber cloth 1 is placed flat on the clamping clamp 5 and clamped. The motor is started, which drives the winding device 8 to rotate, thereby tightening the steel wire rope 7. The traction direction is fixed by the steel wire rope 7. The steel wire rope 7 tightens the clamping clamp 5, and the tension and length of the rubber cloth 1 are adjusted by traction and stretching. After the tension is adjusted to the appropriate position, it is left to stand still and wait for shaping.
