Abstract
The utility model discloses a mould for producing screw rotor, it includes cylindric body (1), and body (1) inner wall is equipped with spiral channel (2) that match with screw rotor (3) external screw thread shape. And a qualified spiral channel can be formed on the outer surface of the pipe body only by penetrating the pipe body through the die by matching with certain equipment. The utility model belongs to the technical field of the mould.
Description
Technical field
The utility model relates to technical field of mold, specifically is a kind of mould that is used to produce screw rotor.
Background technology
The screw rotor of prior art is generally cylindrical body, and the outer surface of this screw rotor is provided with a plurality of spirality channels, like Fig. 1, shown in Figure 2.Existing screw rotor all adopts the lathe turning cylindrical body to form, and manufacturing procedure is loaded down with trivial details, complicated, and labor cost is high.
The utility model content
The technical problem that the utility model will solve is; Overcome the defective of above prior art; A kind of mould that is used to produce screw rotor is provided; It adopts body as the screw rotor body, and need not only needs that body is passed this mould and can form qualified spirality channel at outer surface of tube body the turning processing of body surface.
The technical scheme of the utility model is, a kind of mould that is used to produce screw rotor, and it comprises cylindric body, inner body wall is provided with the spirality channel that matches with screw rotor external screw thread shape.
Described spirality channel is five.
The beneficial effect of the utility model is: the mould that the utility model is used to produce screw rotor cooperates certain device, and the hollow body of cylindricality is passed mould, through finish draw, pull out, extend, disposablely processes needed screw rotor; Therefore need not only needs that body is passed this mould and can form qualified spirality channel at outer surface of tube body the turning processing of body surface.
Description of drawings
Fig. 1 is the screw rotor sketch map.
Fig. 2 is the screw rotor vertical view.
Fig. 3 is the utility model vertical view.
Fig. 4 is the utility model side view.
Among the figure, 1. body, 2. spirality channel, 3. screw rotor.
The specific embodiment
Below be the utility model preferred embodiment, but therefore do not limit the protection domain of the utility model.
In conjunction with Fig. 3, shown in Figure 4, a kind of mould that is used to produce screw rotor, it comprises cylindric body 1, body 1 inwall is provided with the spirality channel 2 that matches with screw rotor 3 external screw thread shapes.
Described spirality channel 2 is five.
Be provided with spirality channel 2 in the utility model mould, be used to produce hollow screw rotor 3 shown in Figure 1, the utility model is that cooperating equipment uses, and during cooperating equipment, the utility model rotates, and screw rotor 3 passes the passage translation of mould.So just can form the spirality lines on screw rotor 3 surfaces.
Claims (2)
1. mould that is used to produce screw rotor, it is characterized in that: it comprises cylindric body (1), body (1) inwall is provided with the spirality channel (2) that matches with screw rotor (3) external screw thread shape.
2. the mould that is used to produce screw rotor according to claim 1 is characterized in that: described spirality channel (2) is five.
