Description
Technical field
The utility model relates to spiral manufacturing technology field, is specifically related to a kind of spliced abrasion-resistance screw using wear-resisting steel plate to make.
Background technology
Helicallobe is widely used in the apparatus field such as conveyor screw, shield machine, cement concrete waggon.Usually adopt general steel plate to carry out there is stretching during the making of existing helicallobe (as shown in figure), roll, the method such as mould die mould makes, manufacturing procedure is complicated, service life is short.
In order to solve the problem, the manufacturing enterprise of helicallobe easily expects that making helicallobe by wear-resisting steel plate increases its service life, but wear-resisting steel plate has elastic deformation characteristic, during making, material rebounds amount is large, helicallobe cannot be made by the method stretched or roll, will first simulate tangible mold profile according to springback capacity analog result when adopting drawing method to make, then weld out die face with section, its complex manufacturing technology, cost are high, the cycle is long; In addition, the existing helicallobe adopting stretching or roll, blade standardization level is low, must all change when helicallobe localized wear, is not easy to safeguard.
Utility model content
The difficult problem that when using wear-resisting steel plate to make helicallobe to overcome, material rebounds amount is large, provides that a kind of processing technology is simple, the spliced abrasion-proof helical blade of long service life.
For achieving the above object, the technical solution adopted in the utility model is as follows: a kind of spliced abrasion-proof helical blade, comprise helicallobe body, it is characterized in that: described helicallobe body comprises the blades that polylith uses wear-resisting steel plate bending, the development size of this whole blades and each block blades identical with the development size of helicallobe body forms according to the size bending of one section of helicallobe body respectively, and described polylith blades splices successively according to the structure of helicallobe body and fixedly forms.
Further, helicallobe body is cone helicallobe.
Further, helicallobe body is right angle helicallobe.
Further, be fixedly connected by welding between adjacent blades.
Further, connected by bolt-locking between adjacent blades.
From above-mentioned to description of the present utility model, compared with prior art, the spliced abrasion-proof helical blade that the utility model provides, the structure composition helicallobe body of the blades splicing of making by using wear-resisting steel plate, not only simplify manufacture craft, overcome the difficult problem using wear-resisting steel plate springback capacity large, and the standardization level of helicallobe body is high, can change according to the local of degree of wear to helicallobe body, be easier to safeguard.
Accompanying drawing explanation
Fig. 1 is the structural representation of helicallobe in prior art.
Fig. 2 is the structural representation of the spliced abrasion-proof helical blade of the utility model.
Fig. 3 is the structural representation of the spliced abrasion-proof helical blade blades of the utility model.
Detailed description of the invention
Below by way of detailed description of the invention, the utility model will be further described.
With reference to shown in Fig. 2, Fig. 3, a kind of spliced abrasion-resistance screw, comprises helicallobe body 1 and blades 11;
Helicallobe body 1 is cone helicallobe or right angle helicallobe;
Blades 11 comprises polylith, the development size of blades 11 and measure-alike each blades 11 bending after respectively with one section helicallobe body 1 identical with the development size of helicallobe body 1, each blades 11 is one_to_one corresponding with helicallobe body 1, when blades 11 makes, first according to the expansion drawing measure of helicallobe body 1, then according to the expansion drawing size bending of helicallobe body 1;
Polylith blades 11 splices successively according to the structure of helicallobe body 1 and fixedly forms, by welding or connected by bolt-locking between adjacent blades 1.
Above are only some detailed description of the invention of the present utility model, but design concept of the present utility model is not limited thereto, all changes utilizing this design the utility model to be carried out to unsubstantiality, all should belong to the behavior of invading the utility model protection domain.
