Problems solved by technology

The disadvantage of this method is that the radians and radii of each pier and pier are different, which requires a mold for each pier and each pier, but in this method, the mold needs to be vulcanized and kept fixed without deformation , so there are strict requirements on the material, specifications, and smoothness of the mold, which makes the manufacturing cost of the mold very high, and the reuse rate of the customized mold is low, which makes the fender manufacturer have no profit margin to produce according to this method, so this method cannot be obtained. to promote

Embodiment 1-5

[0042] The technical solution provided in this embodiment is: an arc-shaped rubber fender, which is an arc-shaped hollow structure as a whole, including a rubber layer and a through hole; fit.

[0043] Wherein, the bottom surface is arc-shaped, the radius and radian are adjustable, and the bottom surface is provided with mounting holes.

[0044] Wherein, the radius of its bottom surface is 1-2 meters, and the radian is 60°-90°.

[0045] Wherein, the cross-sections of the rubber fender and the through hole are D-shaped; the D-shape is curved at the upper part, vertical at the middle and horizontal at the bottom.

[0046] The preparation method of the above-mentioned arc-shaped rubber fender comprises the following steps:

[0047] Step 1: Mix the raw materials according to the proportion, put them into the internal mixer for mixing, and obtain the primary glue;

[0048] Step 2: put the initial rubber into the extruder to obtain a semi-formed rubber; the discharge port of the ...

Abstract

The invention belongs to the technical field of rubber fenders, and in particular relates to a circular-arc-shaped rubber fender as well as a method and equipment for making same. The whole circular-arc-shaped rubber fender has a circular-arc-shaped hollow structure, and comprises a rubber layer and a through hole; the bottom face of the rubber fender is in a smooth curve shape, and is jointed with the surface of a curve-shaped wharf or pier; the method comprises the following steps: 1, mixing the raw materials according to a ratio, and putting the obtained mixture into an internal mixer for mixing to obtain primary rubber; 2, putting the primary rubber into an extruder to obtain a semi-molded rubber material, wherein a discharge hole of the extruder is set into a closed loop type; 3, fixing the semi-molded rubber material in a sizing device, and vulcanizing to obtain the circular-arc-shaped rubber fender. The fender provided by the invention can be used for protecting buildings such as the circular-arc-shaped wharf and pier; the preparation method provided by the invention has the characteristics of being low in cost and easy to popularize.

Description

technical field [0001] The invention belongs to the technical field of rubber fenders, and in particular relates to an arc-shaped rubber fender, its preparation method and manufacturing equipment. Background technique [0002] Conventional fenders are long strip type, drum type, and cylindrical type. They generally have a flat installation surface, installed on the prefabricated plane of the wharf, and achieve good contact with the wharf surface, but many wharf corners , The corners of the piers are all arc-shaped, and conventional fenders cannot be installed. [0003] For example, the Chinese invention patent application with application number 201510541392.7 discloses a marine fender, including a buffer body, fixed sides are symmetrically arranged on both sides of the buffer body, and the buffer body is arranged as a rectangular tubular structure with an arc at one end , fixed holes are arranged on the fixed side; although the buffer body is designed to be arc-shaped in t...
