Item Number:
spiral blade
Product Name:
spiral blade
Description:
It can roll out different kinds of blades to meet different demands by adapting some parts.At the present time, the way to produce blades interiorly : single piece stamping and welding forming, extrusion forming, winding forming, cold rolling forming and any other methods. The method of cold rolling forming has the character of high produce efficiency, reduce the consume of rare material, high quality blade, high strength, good abrasion resistance. The factors that impact the rolling forming: material and thickness of the carbon, offset of the roll. high degree of feeding, roller force, steerable wheel, specification of blades, and raised temperature of roller in the course of rolling.Our company has manufactured this kind of blade which can be made by cold rolling continuously, it has some special characters: smooth surface, high rigidity, abrasion resistance, cold rolled once, without welding continuously.
Features:
1. cold rolling continuously to make sure smooth surface, clear shape, high precision, is favorable to the transportation of the material, reducing the breakage and enhancing the transport efficiency.
2. cold rolling blade is easy to install, can improve the produce efficiency and make the fees lower.
3. cold rolling blade can enhance the ability of rust-proof, and then improve the surface quality of spiral transportation after physical and chemical surface treatment.
Specification:
4. cold rolling blade can be characterized by cold hardening through cold rolling, strength and abrasion resistance can be improved in double, strength of the edge can raised to HB240
5. spiral blade, also known as spiral blade with no spindle or cold rolling spiral blade continuously, can be applicated in kinds of transportation devices, for example, auger or any other kinds of transportation devices.
Safety Approval:
Product Description: Continuous cold rolled once spiral blade, without welding, easy to install and we can accord to the customer's requests to produce the spiral blade with arbitrary outer diameter, arbitrary diameter, arbitrary length, arbitrary pitch, arbitrary thickness and arbitrary direction.
Processing range: outer diameter 35-800mm; inside diameter 12-750mm;pitch 30-800mm; thickness 1.5-8mm; and the length we can afford the products to the customer's requests.
Application: the products mainly applicate to the combine harvester, corn threshing machine, feed processing machinery, screw conveyer, cement machine ( earth auger, drilling machine ), snow plough ( snow blower ) and any other machine's transmission devices.
