Problems solved by technology

Manual wrench is also called ordinary wrench. It is mainly used in ordinary life and work. Its use is relatively simple. Wrench is divided into metal wrench, plastic wrench, and rubber belt wrench according to different materials. Among them, hardware is the earliest and most widely used. The rubber belt wrench developed for the first time is similar to the hardware adjustable wrench, and the adjustable wrench has requirements for the fasteners when it is applied. It must be a regular polygon, and the size range of the fasteners is also required. Due to the adjustable wrench The movable distance is limited, and the nuts that can be used are also within a certain range, and the processing technology of the hardware wrench is relatively complicated, and the cost of the tool is high. Generally, it is equipped with professional personnel and is not used much at home.
Plastic wrenches are also used now, mainly because the versatility of plastic wrenches is better than that of hardware wrenches, the operation is flexible, and the cost is low. However, plastic wrenches also have inherent defects, that is, poor flexibility, temperature resistance, chemical resistance, and high failure rate. Comparative limitations of application

Abstract

The invention relates to a rubber belt wrench and a manufacturing method of a rubber belt of the rubber belt wrench, the rubber belt wrench comprises the rubber belt and a wrench body, and at least one rubber band line is arranged in the rubber belt, the main material of the rubber belt is nitrile rubber, the rubber material is mainly used for manufacturing oil-resistant rubber products, the manufactured products are extremely good in oil resistance, high in abrasion resistance, good in heat resistance and high in bonding force, meanwhile, an environment-friendly plasticizer is added, the performance of the products is more stable, the cold-resistant effect is better, by using N550 carbon black and N774 carbon black as reinforcing agents, the tensile strength and the fatigue life of the rubber can be improved, the rubber material can be endowed with relatively good comprehensive performance when the two are used together, the wrench body is mainly used for providing a handheld position, is made of PP materials, and has high impact resistance, strong mechanical property and resistance to corrosion of various organic solvents, acids and alkalis. The rubber band lines have the characteristic of small flexibility, so that the rubber belt has good stiffness, and the strength and the tensile force of the rubber belt are effectively improved.

Description

【Technical field】 [0001] The invention relates to the technical field of wrenches, in particular to a rubber belt wrench and a method for manufacturing the rubber belt. 【Background technique】 [0002] A wrench is a commonly used installation and removal tool, and it is also a hand tool that uses the principle of leverage to twist bolts, screws, nuts, and other openings or casings that are threaded to hold bolts or nuts. Wrenches are usually formed with openings or sockets for clamping bolts or nuts at one or both ends of the handle. When in use, an external force is applied to the shank in the direction of thread rotation, so that the bolt or nut can be twisted. Manual wrench is also called ordinary wrench. It is mainly used in ordinary life and work. Its use is relatively simple. Wrench is divided into metal wrench, plastic wrench, and rubber belt wrench according to different materials. Among them, hardware is the earliest and most widely used. The rubber belt wrench dev...
