Abstract
The utility model relates to mechanical parts, and aims to provide a rotary extrusion plunger barrel capable of improving the structural strength of the plunger barrel part and reducing the manufacturing cost. The rotary extrusion plunger barrel includes a plunger barrel body, wherein a nozzle is arranged at the bottom of plunger barrel body, and a connecting part is formed by the internally-expanded top wall of the plunger barrel body. The rotary extrusion plunger barrel integrates the original 3 functional structures, namely, the nozzle, the plunger barrel and the connecting piece, into a part, thereby correspondingly reducing the connecting points, improving the structural strength, and reducing the production cost.
Description
Technical field
The utility model relates to mechanical part, particularly relates to a kind of spinning plunger tube.
Background technique
Referring to shown in Figure 1, the structure of former plunger tube parts comprises: plunger tube 1, nozzle 2, spring seat 3 and end cap 4, nozzle 2 is fixed on the bottom of plunger tube 1 by screw thread, the top of plunger tube 1 is provided with spring seat 3, and on the outer wall of the plunger tube 1 and top that is positioned at spring seat 3 is provided with end cap 4, and these 4 relatively independent parts are combined by welding or the mode that is threaded, this plunger tube complex structure, manufacturing procedure is long, belongs to the simple superposition of general structural function parts, and cost is higher.
The model utility content
For solving the problems of the technologies described above, the utility model provides a kind of can improve plunger tube modular construction intensity, lowers the spinning plunger tube of manufacture cost.
Spinning plunger tube of the present utility model comprises the plunger tube cylindrical shell, and the bottom of described plunger tube cylindrical shell is provided with nozzle, and the roof of described plunger tube cylindrical shell extends internally and forms a joint.
Spinning plunger tube of the present utility model, described nozzle and plunger tube cylindrical shell are formed in one.
Spinning plunger tube of the present utility model, described joint and plunger tube cylindrical shell are formed in one.
Compared with prior art the beneficial effects of the utility model are: the utility model is integrated into a part to original 3 functional structures (nozzle, plunger tube, link), has reduced corresponding tie point, and the structural strength of raising itself lowers cost of production.
Description of drawings
Fig. 1 is the structural representation of former plunger tube parts;
Fig. 2 is a structural representation of the present utility model.
Embodiment
Below in conjunction with drawings and Examples, embodiment of the present utility model is described in further detail.Following examples are used to illustrate the utility model, but are not used for limiting scope of the present utility model.
As shown in Figure 2, a kind of spinning plunger tube comprises plunger tube cylindrical shell 1, and the bottom of plunger tube cylindrical shell 1 is provided with nozzle 2, and the roof of plunger tube cylindrical shell 1 extends internally and forms a joint 3.
