Abstract
The utility model relates to a combined extruding shaft set using in hot extrusion of tube material, in particular suitable for the extrusion of component of high strength tube. The utility model comprises an upper extruding shaft and a lower extruding shaft which are connected with each other by connecting bolt. The junction between the connecting bolt and the combined shaft set is provided with a fragile part which is exactly positioned on site where the extruding shaft goes out of an extruding cylinder. The utility model can prevent breakage of body of the extruding shaft and improve production efficiency. Confirmed by test, the utility model can improve efficiency of more than 30 percent in extruding and molding of high strength tube. In extrusion of high temperature alloy tube blank, the utility model overcomes the deficiency of large distortion fore, short service life of the extruding shaft and adverse fraction force. The combined extruding shaft set has long service life.
Description
Technical field
The utility model relates to a kind of tubing hot extrusion with the combination extrusion axis, is particularly suitable for the extruding production of high-strength material tubing part.
Background technology
The tubing extrusion process has many outstanding advantages, as reduces raw-material consumption, with machining mutually specific production rate can increase substantially; After crimp, the grain structure of metal material is fine and close more; Because fibr tissue does not destroy during extrusion molding, and the intensity of extrusion is obviously improved.Because extruding can be saved material and machining period, therefore must reduce production costs; Some complex-shaped symmetrical components are processed in hot extrusion, and effect is obvious especially; Can obtain high dimension precision and surface smoothness.
In the extrude tubes process, used extrusion axis is generally integral structure, and easy unstability during use because unbalance loading and extruding force are very big, the situation of extrusion axis fracture usually occurs in addition, thereby influence production causes economic loss, has also increased production cost.
The utility model content
In order to overcome above shortcoming, the purpose of this utility model provides a kind of tubing hot extrusion that can avoid rupturing with making up extrusion axis under the unbalance loading situation.
To achieve these goals, the technical solution of the utility model is: be made up of upper and lower extrusion axis two parts, adopt connecting bolt to be screwed together with upper and lower extrusion axis respectively;
The position that described connecting bolt is screwed together on the combination extrusion axis is located at easily broken place, promptly goes out the place of recipient at extrusion axis; The hardness of described connecting bolt, intensity are and are lower than the extrusion axis body.
The utlity model has following advantage:
1. can prevent the fracture of extrusion axis body, the production efficiency height.Through experimental check, the utility model combination extrusion axis does not generally destroy owing to be split-type structural, and by contrast, the monoblock type extrusion axis but is easy to fracture in the prior art; So, adopt the utility model in high-strength material tubing extrusion process, efficient can improve more than 30%.
2. reduce production costs.When pushing for the high temperature alloy pipe, crimp power is big, the extrusion axis life-span is short, the shortcomings such as adverse effect of frictional force, adopts the utility model combination extrusion axis, can increase the service life greatly, reduces cost.The utility model combination extrusion axis is when extrusion axis bears partial load, extrusion axis two-part connecting screw (carbon steel) up and down at first ruptures, thereby avoided the fracture of extrusion axis self, when adopting the utility model combination extrusion axis, only need change connecting screw again, extrusion axis still can continue to use, thereby has saved production cost.General cost can reduce more than 20%.
3. applied range.The utility model combination extrusion axis is not only applicable to high-strength material, can also realize the cylindrical member with same extrusion axis backward extrusion various outer diameter, promptly can change the size of extrusion axis working portion.
Description of drawings
Fig. 1 is the utility model combination extrusion axis structural representation.
Fig. 2 is a specific embodiment of the present utility model.
The specific embodiment
Below in conjunction with drawings and Examples the utility model is described in further detail.
Shown in Fig. 1～2, the utility model combined type extrusion axis 1 is made up of upper and lower extrusion axis 11,12 two parts, adopts connecting bolt 13 that upper and lower extrusion axis 11,12 is screwed together; The position that described connecting bolt 13 is screwed together is located at easily broken position, promptly goes out the place of recipient at extrusion axis; The hardness of described connecting bolt 13, intensity all are lower than upper and lower extrusion axis 11,12 bodies; Present embodiment connecting bolt 13 adopts the 45# steel, and upper and lower extrusion axis 11,12 adopts the 3Cr2W8V material, and diameter is 58～59mm, and the extrusion axis total length is 250mm.
During enforcement the utility model as shown in Figure 2, wherein: 1 is the combination extrusion axis, and 2 be recipient, and 3 be dummy block, and 4 is graphite pads, and 5 be to push pin, and 6 is blank, and 7 is die, and 8 is backing plate.
Adopt combination extrusion axis extruding high temperature alloy (In718) tubing, take off the row parameter and successfully squeeze out qualified tubing.
