Product Description

Auger tool function Continuous helical rolling helical blade auger 1. Spiral forming speed is fast, production efficiency is high, material utilization is high, rigidity is good, and strength is high; 2. The welding assembly is convenient and fast, and the overall strength is good; 3. The thickness of the outer edge is about 1/2 of the thickness of the inner hole. However, after rolling and cooling hardening, the hardness of the outer edge is more than doubled, which correspondingly compensates for the wear resistance of the outer edge; 4. Heat treatment can be carried out as required to improve the surface hardness and wear resistance of the blade; 5. The forming size is limited; Only low carbon steel spiral blades with thickness ≤ 8mm and maximum radius difference (outer diameter/inner diameter/2) ≤ 165mm can be formed; 6. The one-time commissioning before production consumes a lot of materials, which is not applicable to the one-time small batch supply of a specification, and there is a minimum order quantity requirement. Product material: SPHC Product specification: within the scope of meeting the following table, customized production according to customer requirements.

Inner hole plate thickness (mm)	Minimum inner diameter (mm)	Maximum outer diameter (mm)	Maximum radius difference (mm)	Pitch outer diameter ratio	Outer diameter inner diameter ratio
3.0	20	500	165	0.6-1.3	4.0
3.5	20	500	165	0.6-1.3	4.0
4.5	28	500	165	0.75-1.3	4.0
5.0	28	500	165	0.8-1.3	4.0
6.0	40	500	165	0.8-1.2	4.0

Features of 18-inch column hole auger

1. If the inner diameter of the customized specification is required to be within the range of the minimum inner diameter+5mm, the maximum outer diameter of the specification cannot exceed three times of the inner diameter. 2. Due to material preparation, the product weight of an order must be greater than 15 tons for the order whose plate thickness is not within the range of the above table.
