ABSTRACT
This paper describes the design and calculation process of the GDC970/75 roll forming machine , forming machine structure and working process of analysis and design of the components used in the check.
With the development of society, green is the future development direction of its briquette with uniform particle size and reactivity strong, good thermal stability and Smoke desulfurization characteristics of the majority is being recognized and accepted by users.
Industry roll-type forming machine is a crucial device applied to the manufacturing of shape-coal. It’s a kind of engineering machine. Roll-type machine consists of units such as pressing rolls, bearing, feeding system, bearing beam ,three-staged velocity-reduction gearbox (transmission system), lubricating system, and hydraulic pressing system, etc .compared conventional forming machine ,with heavy-burden and inadequate rigidity, it is of small-volume,;low-weight and low-cost.
Double rolls have a direct relation to the forming-quality of shape-coal. Industry shape-coal is a new-type of clean ,effective fuel which is widely applied to various industry field such as metallurgical industry ,manufacturing industry chemical fertilizer, calcium carbide and has a vital significance to energys-aving and environment-protection business.
Design in the paper uses expanded–casing and no-key connecting technology and it must be guaranteed that it must be of good centering character-
istic betwween ball groves of the two rolls. Otherwise the forming quality will be
seriously affected. Use expanded-casing and no-key connecting technology, rolls can can be conveniently adjusted by loosning expanded-casing to ensure the forming rate of shape coal.
According to the molding machine structure and working principle of forming machine components of the design, including the design of reducer, Belt Drive, lubrication system, confined stent, pressure roller bearings
Design of structure uses construction of pressing rolls which can be easily removed or easily altered. This kind of structure is of simple-make and bear heavy loads. Hence,the working requirements os large scale roll-type forming maching are satisfied.
Keywords: roll-rype forming machine; shape-coal; hydraulic loading.
