Abstract
The utility model discloses a gas cylinder necking device which comprises a die shank, an upper die plate, a necking die, a guide pillar, an outer supporting sleeve, a backing plate, an ejector rod, a bottom plate and an ejector. The ejector rod is arranged on the bottom plate in a penetrating mode, the backing plate is arranged outside the ejector rod, the outer supporting sleeve is arranged outside the backing plate, the guide pillar is arranged outside the outer supporting sleeve, the necking die is arranged at one end of the outer supporting sleeve, the upper die plate is arranged at one end of the necking die, the die shank is arranged in the upper die plate, and the ejector is arranged at one end of the die shank. According to the gas cylinder necking device, by means of the necking die, an opening portion of a work piece is necked so that the work piece can obtain a required shape and a size. The work piece is smooth in surface, good in quality and small in springback and deformation so that procedures for accurately processing the surface of the work piece in the later period are reduced, and costs are reduced.
Description
Technical field
The utility model relates to a kind of gas cylinder reducing device.
Background technology
At present, reducing is with good cylindrical element or the pipe fitting blank of being shaped in advance, a kind of forming process of its oral area being dwindled through the reducing mould.The application of reducing operation is more extensive, can be used for the processing of parts such as cartridge case, gun shell, steel gas cylinder, cycle frame standpipe, saddle saddle pipe.To elongated tubulose class part, replace pull and stretch can obtain better effect with reducing sometimes.Society is for adapting to modern step now, and a lot of factories have all adopted streamline production, make large-scale batch production become possibility, and this just needs a kind of high efficiency, low cost, the measured gas cylinder reducing of matter processing unit (plant).
The utility model content
The utility model purpose: the purpose of the utility model is in order to solve the deficiency of prior art, to provide a kind of simple in structure, easy to operate, the even and ganoid gas cylinder reducing device of workpiece deformation.
Technical scheme: in order to realize above purpose, the described a kind of gas cylinder reducing device of the utility model, it comprises: die shank, cope match-plate pattern, reducing die, guide pillar, outer supporting sleeve, backing plate, push rod, base plate and backing-out punch; Described push rod is located on the base plate; The outside of push rod is provided with backing plate, and the outside of backing plate is provided with outer supporting sleeve, and the outside of outer supporting sleeve is provided with guide pillar; One end of outer supporting sleeve is provided with reducing die; One end of reducing die is provided with cope match-plate pattern, is provided with die shank in the cope match-plate pattern, and an end of die shank is provided with backing-out punch.
Described cope match-plate pattern and guide pillar are realized fastening through one group of bolt.
Described outer supporting sleeve and base plate are realized fastening through one group of bolt.
The middle of described backing plate and backing-out punch is provided with workpiece.
Beneficial effect: a kind of gas cylinder reducing device that the utility model provides; Through reducing die the workpiece oral area is dwindled; Thereby make workpiece obtain the required form size; Because smooth surface, the quality of workpiece are good, resilience is little, practiced thrift the later stage and need carry out the operation that surface accuracy is processed workpiece, reduced cost.
Description of drawings
Fig. 1 is the full sectional view of the utility model.
The specific embodiment
Below in conjunction with accompanying drawing, further illustrate the utility model.
As shown in Figure 1, the described a kind of gas cylinder reducing device of the utility model, it comprises: die shank 1, cope match-plate pattern 3, reducing die 4, guide pillar 5, outer supporting sleeve 6, backing plate 7, push rod 8, base plate 9 and backing-out punch 10.
Described push rod 8 is located on the base plate 9; The outside of push rod 8 is provided with backing plate 7, and the outside of backing plate 7 is provided with outer supporting sleeve 6, and the outside of outer supporting sleeve 6 is provided with guide pillar 5; One end of outer supporting sleeve 6 is provided with reducing die 4; One end of reducing die 4 is provided with cope match-plate pattern 3, is provided with die shank 1 in the cope match-plate pattern 3, and an end of die shank 1 is provided with backing-out punch 10.
Described cope match-plate pattern 3 is realized fastening with guide pillar 5 through one group of bolt 2.Described outer supporting sleeve 6 is also realized fastening through one group of bolt 2 with base plate 9.
The middle of described backing plate 7 and backing-out punch 10 is provided with workpiece 11.
When needs carry out reducing to workpiece 11; Earlier workpiece 11 is fixed on the backing plate 7, fixing in the outside of workpiece 11 again with outer supporting sleeve 6, prevent that workpiece 11 from moving axially; Be provided with cope match-plate pattern 3 on the top of workpiece 11; When cope match-plate pattern 3 when pressing down, the reducing die 4 on the cope match-plate pattern 3 dwindles the oral area of workpiece mouth 11, thereby obtains the required size of workpiece 11.Because the resilience after the reducing distortion, therefore, the size of die internal diameter is bigger slightly than the reducing size of workpiece.
After the reducing of workpiece 11 is accomplished, with push rod 8 workpiece 11 is ejected from outer supporting sleeve 6, because of the reducing of workpiece 11 partly is against in the reducing die 4, at this moment, with backing-out punch 10 workpiece 11 is ejected from reducing die and to get final product.
Above-mentioned embodiment only is the technical conceive and the characteristics of explanation the utility model, its objective is to let to be familiar with the also enforcement according to this of content that these those skilled in the art can understand the utility model, can not limit the protection domain of the utility model with this.All equivalents or modifications of being made according to the utility model spirit all should be encompassed within the protection domain of the utility model.
