Rubber ring expansion device and using method thereof

Abstract

The invention discloses a rubber ring expansion device and a using method thereof. The rubber ring expansion device is characterized by comprising two semicircular expansion rings which are correspondingly matched. A semicircular boss is arranged at the lower end of each semicircular expansion ring, a slant rotating handle is welded on the outer side of each semicircular boss, and the rotating handles are fixed through a fixing clamp. The using method includes: firstly, closing the rubber ring hole expansion device to enable the two semicircular expansion rings to form a complete circle, and holding the rotating handles with two hands to open towards two sides so that the semicircular bosses can be separated in a sector way along with force of the rotating handles, the radius of the circle is increased and a rubber ring can be expanded. The rubber ring expansion device is reasonable in structural design, simple to manufacture, low in cost, and safe, convenient and simple to apply, has zero damage on the rubber ring and is easy to operate by operators, mounting of the rubber ring can be mounted by one person, and labor efficiency is greatly improved.

Description

technical field [0001] The invention relates to the assembly problem between the roller table of the annealing kiln and the apron, belongs to the field of mechanical assembly, and in particular relates to an apron hole expander and a use method thereof. Background technique [0002] During the production process of apron rollers, rubber rings need to be placed on the sticks. Each roller needs about 15 aprons on average. Since the inner hole of the aprons is smaller than the outer diameter of the rollers, direct external force is applied to the rollers, which is not only easy to strain Aprons are time-consuming and labor-intensive. Therefore, in order to ensure product quality, reduce labor intensity, and improve labor efficiency, effectively solving this problem can achieve huge economic benefits.

Problems solved by technology

[0003] The purpose of the present invention is to make up for the deficiencies of the prior art, and provide a rubber ring expander and its use method, which solves the problem of directly applying external force to the rubber ring to make it fit on the roller, which is easy to damage the rubber ring and takes time. It takes a lot of work, and the product quality is not easy to guarantee, etc.
