Description
Technical field
The utility model relates to a kind of wheel rim body heat pressing forming device.
Background technology
The various wheel rim body of producing during engineering is made, its diameter, length, thickness are all inequality.The wheel rim body traditional processing is the weldment structure, and promptly wheel rim body is welded after being processed respectively with gutter ring 15 two parts by interior wheel rim body 14, and interior wheel rim body and gutter ring have pad 16 (as shown in Figure 3).The deviation from cylindrical form of the wheel rim body that this traditional processing method is made is bigger, and difficult control, and commissure, welding back needs the sand milling polishing, and operation is many, and processing cost is high.
The utility model content
The utility model is the weak point that exists in the above-mentioned prior art for avoiding, and a kind of wheel rim body heat pressing forming device is provided, with the working (machining) efficiency that improves wheel rim body and cut down finished cost.
The utility model adopts following technical scheme for the technical solution problem.
Wheel rim body heat pressing forming device, its design feature are to comprise cope match-plate pattern, mold, lower bolster, bed die, bulging cone, apical axis and bulging internal mold; Said mold is arranged on the lower surface of said cope match-plate pattern; Said bed die is arranged on the upper surface of said lower bolster; Said apical axis is arranged at the centre of said lower bolster; Said bed die is the cylindrical body of hollow, said bulging internal mold be arranged in the cavity of said bed die and with the coaxial setting of said bed die; The centre of said bulging internal mold is a conical cavity, and said bulging cone is arranged in the said conical cavity and bulging cone and bulging internal mold and the coaxial setting of bed die.
The design feature of the wheel rim body heat pressing forming device of the utility model also is:
The end face of said bulging internal mold and bulging cone is provided with pressing plate, is provided with backing plate between said pressing plate and the cope match-plate pattern.
In the cavity of said bed die, the upper surface of lower bolster is provided with base plate, is provided with the guide rail plate between said base plate and the said bulging internal mold.
Compared with present technology, the utility model beneficial effect is embodied in:
The wheel rim body heat pressing forming device of the utility model, workpiece blank are located between mold and the bulging internal mold in the mold inner chamber.When hot-forming, cope match-plate pattern drives mold and presses down, and directly workpiece blank is pressed into shaping workpiece; This shaping workpiece promptly is the whole rim body of required processing; Reduce production links such as electric welding sand milling, save labour and working time, improve work situation; Thereby reduce production costs, improved working (machining) efficiency.
Description of drawings
Fig. 1 is the structural representation of the wheel rim body heat pressing forming device of the utility model.
Fig. 2 is the wheel rim body of making of the wheel rim body heat pressing forming device of the utility model.
Fig. 3 is the wheel rim body that prior art processing obtains.
Label among Fig. 1～Fig. 3: 1 cope match-plate pattern, 2 molds, 3 pressing plates, 4 backing plates, 5 bulging cones, 6 lower bolsters, 7 bed dies, 8 base plates, 9 guide rail plates, 10 shaping workpieces, 11 apical axis, 12 bulging internal molds, 13 workpiece blanks, 14 interior wheel rim body, 15 gutter ring, 16 pads.
Below pass through the specific embodiment, and combine accompanying drawing that the utility model is described further.
The specific embodiment
Referring to Fig. 1, the wheel rim body heat pressing forming device comprises cope match-plate pattern 1, mold 2, lower bolster 6, bed die 7, bulging cone 5, apical axis 11 and bulging internal mold 12; Said mold 2 is arranged on the lower surface of said cope match-plate pattern 1; Said bed die 7 is arranged on the upper surface of said lower bolster 6; Said apical axis 11 is arranged at the centre of said lower bolster 6; Said bed die 7 is the cylindrical body of hollow, said bulging internal mold 12 be arranged in the cavity of said bed die 7 and with said bed die 7 coaxial settings; The centre of said bulging internal mold 12 is a conical cavity, and said bulging cone 5 is arranged in the said conical cavity and bulging cone 5 and bulging internal mold 12 and bed die 7 coaxial settings.The wheel rim body heat pressing forming device of the utility model, workpiece blank 13 are located between mold and the bulging internal mold in the mold inner chamber.When hot-forming, cope match-plate pattern drives mold and presses down, and directly workpiece blank 13 is pressed into shaping workpiece 10; The whole rim body that this shaping workpiece 10 promptly is required processing; Reduce production links such as electric welding sand milling, save labour and working time, improve work situation; Thereby reduce production costs, improved working (machining) efficiency.
The end face of said bulging internal mold 12 and bulging cone 5 is provided with pressing plate 3, is provided with backing plate 4 between said pressing plate 3 and the cope match-plate pattern 1.Through pressing plate and backing plate are set, avoid mold to press down excessively, improve the yield rate of product.
In the cavity of said bed die 7, the upper surface of lower bolster 6 is provided with base plate 8, is provided with guide rail plate 9 between said base plate 8 and the said bulging internal mold 12.
The wheel rim body heat pressing forming device of the utility model adopts hot-forming processing, under HTHP; The easy moulding of metal, and adopt bulging formula internal model structure, workpiece is prone to put into mold cavity; Workpiece can conveniently take out from mould after the moulding, and wheel rim body receives the internal mold swelling pressure, and deviation from cylindrical form also reduces accordingly; Improve product quality, successfully solved the jumping-up problem of wheel rim body one end end 22 * 28mm.
The wheel rim body that hot-forming entire pressurisation forms, one of which end end 22 * 28mm structure is processed by hot pressing.Because without electric welding splicing, thus the wheel rim body surfaces externally and internally circularity and cylindricity greatly improve, guaranteed the total quality of wheel rim body.Compare with traditional processing technology, saved operations such as electric welding, sand milling, saved the labour, thereby reduced production cost greatly.
The wheel rim body heat pressing forming device of the utility model has successfully solved the crucial difficult problem of 22 * 28mm position, wheel rim body one end end jumping-up.For making wheel rim body blank (cylinder) after adding man-hour and moulding, can put into mould easily and take out from mould, internal mold adopts bulging formula structure, and workpiece receives the swelling pressure effect of internal mold simultaneously, greatly reduces deviation from cylindrical form.
Through above-mentioned description, the related personnel can change and revise under the condition of the mentality of designing of the utility model and technical indicator appointment.The technical scope of the utility model is not limited to the content on the specification, must confirm technical scope according to the claim scope.
