Description

Technical Field

[0001] The utility model relates to the technical field of floating body production, in particular to a jig for producing a floating box. Background Art

[0002] A pontoon is a fixed floating device commonly found in inland rivers and offshore areas. It can be used for water operations, floating bridge construction, and water platform construction.

[0003] Existing pontoon production is done by blow molding, a plastic processing method in which a thermoplastic resin is extruded or injection molded to obtain a tubular plastic preform. This is then placed in a split mold while hot or heated to a softened state. After the mold is closed, compressed air is immediately introduced into the preform to inflate the plastic preform and cling to the inner wall of the mold. After cooling and demolding, various hollow products are obtained.

[0004] Some pontoon products have thin walls and dissipate heat quickly, so the shrinkage phenomenon is not obvious. However, for some pontoon products with thick walls, due to their high processing temperature and slow heat dissipation, more obvious shrinkage will occur after the products are finished, seriously affecting the quality and appearance of the pontoon products.

[0005] In response to the above problems, the applicant has proposed a solution. Utility Model Content

[0006] The present invention aims to solve at least one of the technical problems existing in the prior art. To this end, the present invention proposes a jig for producing a pontoon, which adopts the following technical solutions:

[0007] A jig for producing a pontoon comprises a frame, a placement slot for placing the pontoon is provided on the frame, and clamping mechanisms for clamping side ends of the pontoon are respectively provided on both sides of the frame.

[0008] According to a jig for producing a pontoon according to an embodiment of the present invention, the clamping mechanism includes clamping platforms provided at both side ends of a frame, and clamping components located at the clamping platforms.

[0009] According to a jig for producing a pontoon according to an embodiment of the present invention, the clamping assembly of the frame at least on one end portion thereof can move back and forth on the clamping table to adjust the distance between the two clamping assemblies.

[0010] According to a jig for producing a pontoon according to an embodiment of the present invention, the clamping assembly includes a pressing seat and a pressing device. The pressing seat is arranged on the clamping platform, and the pressing device can be controllably pressed on or released from the pressing seat.

[0011] According to a jig for producing a pontoon according to an embodiment of the present invention, the clamping device includes a clamping lever suspended on a clamping seat, and a drive motor arranged behind the clamping seat. A fulcrum bracket is provided between the front and rear ends of the clamping lever. The rear end of the clamping lever is connected to the drive motor and is driven by the drive motor to perform a lever movement so that the front end of the clamping lever is pressed on the clamping seat or released.

[0012] According to a jig for producing a pontoon according to an embodiment of the present invention, a pressing head is provided at the front end of the pressing lever.

[0013] According to a jig for producing a pontoon according to an embodiment of the present invention, a pressing groove is provided on the pressing seat.

[0014] Compared with the prior art, the beneficial effects of the present invention are:

[0015] After the pontoon product is blow-molded and demolded, it is placed on the placement slot of the frame so that the two sides of the pontoon product are close to the clamping mechanism, and then the side ends of the pontoon product are clamped by the clamping mechanism until it is cooled and formed to obtain a pontoon product. During the clamping and cooling process, since the side ends of the pontoon product are clamped, they cannot shrink significantly and can only shrink slightly, which greatly ensures the increase in the output of the pontoon product and the quality of the appearance and finished product.

[0028] After the pontoon product is blow-molded and demolded, it is placed on the placement slot 20 of the frame 10, so that the two sides of the pontoon product are close to the clamping mechanism, and then the side ends of the pontoon product are clamped by the clamping mechanism until it is cooled and formed to obtain a pontoon product. During the clamping and cooling process, since the side ends of the pontoon product are clamped, they cannot shrink significantly and can only shrink slightly, which greatly ensures the increase in the output of the pontoon product and the quality of the appearance and finished product.

[0029] like Figure 1As shown, the floating box 90 includes a hollow box body 91 and connecting ears 92 on both sides thereof. Therefore, there is a thickness difference between the box body 91 and the connecting ears 92. The depth of the placement slot 20 needs to be determined according to the specific thickness of the box body 91. As long as the box body 91 is placed in the placement slot 20, the connecting ears 92 on both sides thereof are close to the clamping mechanism. When in use, the clamping mechanism clamps the connecting ears 92.

In the embodiment, the clamping assembly is adjusted by cooperating with the screw 40, the screw 41 and the nut 42.

[0032] In some embodiments of the present invention, Figure 2 、 3 As shown, the clamping assembly includes a clamping seat 50 and a clamping device. The clamping seat 50 is provided on the clamping platform 30. The clamping device can be controllably pressed or released on the clamping seat 50. The connecting ear 92 of the buoyancy box 90 is pressed on the clamping seat 50 when in use. Specifically, the clamping device includes a clamping lever 60 suspended on the clamping seat 50 and a drive motor 70 provided behind the clamping seat 50. A fulcrum bracket 80 is provided between the front and rear ends of the clamping lever 60. The rear end of the clamping lever 60 is connected to the drive motor 70 and is driven by the drive motor 70 to perform a lever movement so that the front end of the clamping lever 60 is pressed or released on the clamping seat 50. When clamping is required, the drive motor 70 drives the rear end of the clamping lever 60 to lift up, so that the front end of the clamping lever 60 is pressed downward.
