Abstract
The utility model discloses a combined Haff elbow forming die which comprises a concave die (1) and a convex die (2). The combined Haff elbow forming die is characterized in that the concave die (1) is composed of a steel baseplate (101) and a plurality of concave die steel pieces (102) welded on the steel baseplate (101), each concave die steel piece (102) is provided with a concave-arc notch (103), adjacent concave die steel pieces (102) are connected through spot welding, all concave-arc notches (103) form a groove matched with the outer surface of a formed Haff, the convex die (2) is composed of a mounting steel plate (201) and a plurality of hemispherical convex die steel pieces (202) welded on the mounting steel plate (201), and adjacent hemispherical convex die steel pieces (202) are connected through spot welding. The combined Haff elbow forming die has the advantages of high strength, easiness in manufacturing and lowering of die manufacturing cost, service life of the die can be prolonged, and manufacturing cost of an elbow can be lowered.
Description
Technical field
the utility model relates to a kind of Tool and Die Technology, especially a kind of mould of compressing Hough elbow, specifically a kind of combined type Hough elbow forming die.
Background technology
At present, the plate of industrial use Hough elbow forming die processed, all adopts the method for molten iron casting to make, and goes out punch and die by suppressing corner dimension founding cast molding.Die is the semicircular die cavity that has fixing curvature, and the shape of punch is mutually to coincide with the die cavity of die.This mould has the following disadvantages: the intensity difference of die, in the time of compacting heavy caliber thick wall sheet material, is easy to occur concave die cavity cracking phenomena.Once cracking, must carry out repair welding and repair a die, cause to generate and interrupt, can not complete on time.The local intensity variation of repair welding, can not suppress thicker sheet material again.In use afterwards, the life cycle of mould is shorter and shorter.The mould of same specification bore may need again to manufacture, and causes product cost to increase.Therefore, design a kind of new plate Hough elbow forming die processed and become the task of top priority.
Summary of the invention
The purpose of this utility model is the intensity difference existing for existing casting type Hough elbow forming die, manufacturing cycle is long, the problem that maintenance cost is high, design a kind of low cost, manufacture simple, easy to maintenance, use cost is low is combined into Hough elbow forming die.
The technical solution of the utility model is:
A kind of combined type Hough elbow forming die, it comprises die 1 and punch 2, it is characterized in that described die 1 is made up of steel sole plate 101 and the some die steel discs 102 that are welded on steel sole plate 101, die steel disc 102 is provided with concave arc breach 103, between adjacent die steel disc 102, be connected by spot welding, all concave arc breach 103 form a groove matching with shaping Hough appearance; Described punch 2 forms by steel plate 201 being installed and being welded on the some semicircle punch steel disc 202 of installing on steel plate 201, between adjacent semicircle punch steel disc 202, is connected by spot welding.
Described die and the bending radius of punch are 1.0D or 1.5D, D=400-4000 millimeter, and concave arc breach 103 is semicircular structure, the wall thickness of moulding Hough is 12~35 millimeters.
The beneficial effects of the utility model:
The utility model Hough bending mould effectively increases strength of concave mould, easily manufactures, and reduces mould cost, has extended the service life of mould, expands the elbow scope of compacting different wall, has reduced the manufacturing cost of elbow simultaneously.
The utility model is applicable to, for the compacting of small lot or single-piece Hough elbow provides rapid die-manufacturing, save the inconvenience of casting external coordination, greatly shortens the moulding cycle, enhances productivity.
Brief description of the drawings
Fig. 1 is the structural representation of die of the present utility model.
Fig. 2 is the structural representation of punch of the present utility model.
Fig. 3 is die of the present utility model and punch mated condition schematic diagram.
Fig. 4 is the structural representation for the treatment of the steel plate of mould compacting of the present utility model.
Fig. 5 is the structural representation of the Hough elbow of the utility model compacting.
Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is further described.
As Figure 1-5.
A kind of combined type Hough elbow forming die, it comprises die 1 and punch 2, described die 1 is made up of steel sole plate 101 and the some die steel discs 102 that are welded on steel sole plate 101, die steel disc 102 is provided with semi-circular concave arc breach 103, between adjacent die steel disc 102, be connected by spot welding, all concave arc breach 103 form a groove matching with shaping Hough appearance, as shown in Figure 1; Described punch 2 forms by steel plate 201 being installed and being welded on the some semicircle punch steel disc 202 of installing on steel plate 201, is connected, as shown in Figure 2 between adjacent semicircle punch steel disc 202 by spot welding.When concrete enforcement in order to gain in strength, also can gain in strength by the mode that increases connecting plate in the interior outside of die steel disc 102, and punch steel disc 202 also can be gained in strength by increasing semicircle steel pipe mode, now, the impact of the thickness that should consider half rounds pipe on elbow radius.The bending radius scope of application of die of the present utility model and punch is 1.0D or 1.5D, D=400-4000 millimeter, and the wall thickness of moulding Hough is 12~35 millimeters.
When use, the steel plate 3 of the setting-out moulding shown in Fig. 4 is put on the die shown in Fig. 3, started press and punch is depressed to the Hough elbow 4 that can obtain shown in Fig. 5.
The utility model can cut out punch steel disc from monoblock steel plate while manufacture, die steel disc self-assembling formation, then punch steel disc is machined to required size, and carry out spot welding operation, when maintenance, only need change the steel disc of damage, keep in repair without entirety.
The utility model does not relate to partly all prior aries that maybe can adopt same as the prior art to be realized.
