Abstract
The utility model discloses a spinning roller for necking gas bottle in a hot spinning manner. The spinning roller comprises a spinning roller body. A working surface and a guiding surface are arranged on the periphery of the spinning roller body, and an angle ranging from 5 degrees to 15 degrees is formed between the working surface and the central axis of the spinning roller body. As the angle is formed between the working surface and the central axis of the spinning roller, the contact area of the spinning roller and the surface of a preform is decreased, pressure on the working surface is reduced, a working angle of the spinning roller is shortened, the working time of the spinning roller is shortened, the service life is greatly prolonged, and the working efficiency is greatly improved.
Description
Technical field
The utility model relates to gas cylinder and makes the field, relates in particular to a kind of spinning roller that the gas cylinder hot spinning closes up that is used for.
Background technology
Existing spinning manufactured gas cylinder generally is to rotate on the pipe surface through spinning wheel, realizes an end end socket, and the other end closes up and forms bottleneck.One Chinese patent application 201010288774.0 discloses a kind of seamless gas cylinder forward spinning roller hot spinning closing in method, comprises the steps: 1) steel pipe closing in section is heated to 1050～1100 ℃; 2) steel pipe closing in section is carried out 6～7 passage semielliptical shape forwards and seal spinning, obtain semi-ellipsoidal head; 3) again the gained semi-ellipsoidal head is carried out 3～4 passages bottom and thicken spinning; 4) bottleneck shaping spinning; 5) at last polishing spinning is carried out on the end socket surface, thereby the hot spinning of accomplishing seamless gas cylinder closes up.
Be illustrated in figure 1 as the structural representation of existing spinning roller, the periphery of spinning roller body 1 is provided with working face 100 and spigot surface 101, the central axis of working face 100 parallel spinning roller bodies wherein, and spigot surface 101 and working face 100 angulations are greater than 90 °.The spinning roller working face 100 of this structure is behind the pipe of Long contact time high temperature, and the surface be prone to form depression, thus surface quality and yield rate after influencing steel pipe and sealing.
Spigot surface receives the temperature of pipe, effect length bigger in the course of the work, is prone to produce sizing, in the process of sealing, needs to change according to the size of pipe, influence production efficiency.In the process of sealing, spinning roller must vertical pipe, could guarantee the quality of sealing, so has increased the operating angle of spinning roller, has prolonged the working time, influences service life.
Summary of the invention
The utility model provides a kind of spinning roller that the gas cylinder hot spinning closes up that is used for, and has solved the pipe that traditional spinning roller can only adapt to a kind of specification, needs the problem of often changing.
A kind of spinning roller that is used for the gas cylinder spinning closing-in comprises the spinning roller body, and the periphery of said spinning roller body is provided with working face and spigot surface, and described working face becomes 5～15 ° of angles with the central axis of spinning roller body.
The central axis of described spigot surface and spinning roller body at an angle of 90, in the process of sealing, bottle base and working face are tightly fitted, and do not interspace, and eliminate the sizing situation.
Built-up welding has wearing layer on the described working face, to improve the intensity of working face, reduces the probability of distortion.
The utility model spinning roller working face and central axis are at angle; Reduced and the bottle base surface contact area, reduced the suffered pressure of working face, shortened the operating angle of spinning roller; Reduced the working time of spinning roller, life-span and operating efficiency all have been greatly improved.
Description of drawings
Fig. 1 is the structural representation of existing spinning roller;
Fig. 2 is the structural representation of the utility model spinning roller;
Fig. 3 is the utility model spinning roller work sketch map.
The specific embodiment
As shown in Figure 2; A kind of spinning roller that is used for the closing in of gas cylinder hot spinning; Comprise spinning roller body 2, the periphery of spinning roller body 2 is provided with working face 200 and spigot surface 201, wherein the central axis 203 angled R of working face and spinning roller body 2; Angle R size is 10 °, can be chosen between 5～15 ° as required.
As shown in Figure 3, spinning roller body 2 overall fixed are on pivoted arm 4, and the working face of spinning roller body 2 is pasting the surface of bottle base 3; Because working face 200 is angled with central axis; It and bottle base surface contact area are less, and the pressure that also makes it bear is little, the spinning roller body the angle that will rotate also dwindle; Improve operating efficiency and service life, and can be suitable for the bottle base of plurality of specifications.
Claims (3)
1. one kind is used for the spinning roller that the gas cylinder hot spinning closes up, and comprises the spinning roller body, and the periphery of said spinning roller body is provided with working face and spigot surface, it is characterized in that, described working face becomes 5～15 ° of angles with the central axis of spinning roller body.
2. spinning roller according to claim 1 is characterized in that, the central axis of described spigot surface and spinning roller body at an angle of 90.
3. spinning roller according to claim 1 is characterized in that built-up welding has wearing layer on the described working face.
