Recently, the author learned from Zhangjiayu Mining Co., Ltd. that the company's machine repair workshop invented the E-bolt and wire-threading tooling, which effectively solved the problem of recycling and reuse of the E-bolt.
E-bolt is the scraper fastener used in the fully mechanized working face scraper conveyor. The company recycles more than 1,100 E-bolts each year due to moving and reversing. These recovered E-bolts mainly have thread damage and rust. Can not be directly reused, bringing difficulty in recycling and reuse work.
To this end, the machine repair shop invented the E-bolt ferrule tooling according to the cause of the E-bolt breakage. This set of tooling uses the drill reducer sleeve combined with the die profile to make the die fixture, combined with the mechanical principle and custom of the radial drill press. The heart, adjustable speed and other characteristics realize the processing of the ferrule of the E-bolt by the radial drilling machine, which not only improves the working efficiency of the ferrule, but also ensures the processing precision of the ferrule, and makes the E-type after the re-threading repair. The bolts can continue to be used.
It is reported that since the design of this tooling design, the working efficiency of the artificial ferrule has been improved by 4 times. If the purchase price of the E-bolt is calculated at 1,100 yuan, the small Leather is only repaired on the E-bolt. Each year, it can save about 100 million yuan in cost.
It is understood that this year, according to the overall arrangement and deployment of the “all-in-one†work, all grassroots units have taken active actions to set up a number of interest activity groups to fully develop the talents of employees and to create profits and increase efficiency. The goal is to save money for the purpose of providing advice and suggestions for the company's development. Since the launch of the full-time Maker, the workshop has reported 6 Maker Projects, including 4 approvals by the company's full-service creator, and 3 rationalization proposals, for the company's safe production and profit-creating work. Consolidate the foundation.
Cationic Dyes are a class of Basic Dyes. Dyeing speed, poor levelness, high color yield, with the retarding agent can be dyed dark.
Cationic dye affinity for acrylic big, due to the adsorption of fast and slow diffusion staining, easy to produce uneven dyeing phenomenon, and once produced uneven dyeing, dyeing difficult by extending the method to correct time. Cationic Dyes , in order to obtain uniform staining, dyeing rate should be appropriately reduced. Factors affecting the rate of cationic dyes in addition to the type of acrylic, there are temperature, pH value of the dye bath, electrolytes, retarding agent.
