[0075] Figure 4 It is a side view of the first embodiment of the product manufacturing system with cavity equipped with the mandrel fixing and adjusting device of the present invention.

[0076] Such as Figure 4 As shown, the product manufacturing system with a cavity is arranged with a mandrel fixing and adjusting device 10 , a fiber impregnation system 13 and a mold 14 from the left side of the figure. The mandrel fixing and adjusting device 10, the fiber impregnation system 13 and the mold 14 are each firmly connected to the formwork 1 by at least one fastener. One end of the mandrel 8 remains inside the mandrel jacket 7 and maintains a fixed position relative to the mandrel jacket 7 , while the other end extends out from the mandrel jacket 7 .

[0077] The vertical or horizontal position adjustment of the mandrel 8 integrated in the mandrel jacket 7 along its cross section can be realized by the vertical position adjustment screw rod 3 and the horizontal position adjus...

[0079] Figure 5 It is a side view of the second embodiment of the product manufacturing system with cavity equipped with the mandrel fixing and adjusting device of the present invention. This embodiment is provided with a mandrel fixing and adjusting device similar to the first embodiment, and has the same mandrel adjustment method as the first embodiment, the difference being that the mold inlet is not connected with the fiber impregnation device. In this implementation, the fibers are impregnated with resin before entering the mold around a mandrel, where the shape is cured in the cavity formed by the mandrel and the inner wall of the mold.

[0081] Figure 6 It is a side view of the third embodiment of the product manufacturing system with cavity equipped with the mandrel fixing and adjusting device of the present invention. This embodiment is equipped with a mandrel fixing and adjusting device similar to the first embodiment, and has the same mandrel adjustment method as the first embodiment, the difference is that the product manufacturing system with a cavity includes a front and rear direction along the mandrel Arranged two mandrel fixing and adjusting devices. As previously mentioned, each adjustment involves only any one of the two mandrel fixing and adjusting devices arranged along the front and rear directions of the mandrel, while keeping the other mandrel fixing and adjusting device unchanged, so that the mandrel jacket Move linearly along the horizontal or vertical axis of the cross-section of the mandrel without shaking, and change the angle between the mandrel 8 passing through the mandrel jacket 7 a...

Abstract

The invention relates to a mandrel fixing and adjusting device (10). The device comprises a formwork or a base (1) supporting the mandrel fixing and adjusting device (10), a mandrel jacket (7) integrally provided with a mandrel (8) in an integrating manner, adjusting guiding devices (2 and 4), position adjusting devices (3 and 6) and an adjusting locking device (9). The position adjusting devices (3 and 6) are fixed to the mandrel jacket (7) in the cross-axis direction and the longitudinal-axis direction of the cross section of the mandrel correspondingly and adjust the position of the mandrel jacket (7) and the position of the mandrel (8) by adjusting the relative positions of the mandrel jacket (7) and the formwork (1) in a threaded rotary feeding manner. The invention further relates to a belt type cavity product manufacturing system on which the mandrel fixing and adjusting device (10) is assembled, an operation method for the belt type cavity product manufacturing system and a product obtained through the method.

Description

technical field [0001] The invention relates to a mandrel fixing and adjusting device, in particular to a mandrel fixing and adjusting device used in the manufacturing process of a pultrusion product with a cavity. The present invention also relates to an operation method of a product manufacturing system with a cavity equipped with the mandrel fixing and adjusting device, and the operation method is suitable for the manufacturing process of a pultruded product with a cavity. Background technique [0002] There are quite a few products with one or more cavities in pultruded products. The production process of pultruded products with cavity requires not only the use of molds, but also the use of mandrels and corresponding fiber impregnation systems. Therefore, the traditional manufacturing system of products with a cavity adopts the mandrel fixing and adjusting device to adjust the position of the mandrel. [0003] figure 1 A system for manufacturing products with a cavity...
