Abstract
The utility model relates to a forming die forging and punching center positioning device, which is characterized by comprising two positioning units, wherein each positioning unit comprises a transverse frame and a vertical frame, each vertical frame is connected with the center of the corresponding transverse frame and is vertical to the transverse frame, the middle part of each vertical frame is provided with a long groove in the length direction of the vertical frame, the two ends of each transverse frame are respectively provided with positioning rollers with the same diameter, the vertical frames of the two positioning units are hinged through a center positioning block, and the center positioning block penetrates through the long grooves of the vertical frames of the two positioning units. The forming die forging and punching center positioning device has the advantages that the structure is simple, the positioning effect is good, the use is convenient, and the processing precision of products can be improved.
Description
Technical field
The utility model belongs to the auxiliary equipment technical field of heat processing and forming technique, particularly relates to a kind of loose tooling forging punching center positioning device.
Background technology
Swage forging grows up on free_forging basis, has more further formed contour forging technique, and it is a kind of process form between open die forging and die forging, is a transition stage that makes forging Stepwise refinement.Forging form mainly contains three kinds of open die forging, swage forging and hammer die forgings.The forging being shaped with the direct blanking and punching of punching pin in the process of ring forgings fetal membrane forging and molding is more.It is the center placement location that operating personnel estimate punching punching pin, the position of punching pin is regulated to installation, according to the difference in personnel present position and orientation, often deviation is larger for the visual impression producing, and centre bore is larger with respect to the side-play amount of forging cylindrical, causes the uneven thickness of ring forgings, in mechanical processing process because endoporus deflection may be local incomplete, machining accuracy is low, can not meet product drawing requirement, product rejection processing.In order to solve the inaccurate technical problem in above-mentioned location, conventionally the method adopting in prior art is: adopt the overall location-plate of annular to position punching pin, the excircle of location-plate is provided with flange, flange positions with the excircle of mould, the Internal hole positioning drift of location-plate, the design size of location-plate depends on the size of mould cylindrical and the size of drift size, therefore, when different forging mold punching, need the location-plate that manufacturing dimension is different, and need to prepare suitable plate, metal cutting amount is larger, and the manufacturing cycle is longer.In addition, drift forges behind the position of punching gently, takes away drift, takes location-plate away, relays back blanking die, has the secondary deviation of centering center, trivial operations inconvenience, poor operability.
Summary of the invention
The utility model provides a kind of simple in structure, good positioning effect, easy to use, the loose tooling forging punching center positioning device that can improve processing precision of products for solving the technical problem existing in known technology.
The technical scheme that the utility model is taked for the technical problem existing in solution known technology is: a kind of loose tooling forging punching center positioning device, it is characterized in that: comprise two positioning units, described positioning unit comprises that crossbearer is connected and the vertical frame vertical with described crossbearer with described crossbearer center, the middle part of described vertical frame is provided with along the elongated slot of vertical frame length direction, and the registration roller that diameter is identical is installed respectively at the two ends of described crossbearer; The vertical frame of described two positioning units is hinged by centralized positioning piece, and described centralized positioning piece runs through the elongated slot of the vertical frame of described two positioning units.
The utility model can also adopt following technical scheme:
Described crossbearer and vertical frame are integral type structure.
Advantage and the good effect that the utlity model has are: because the utility model adopts as above technical scheme, design a kind of device that loose tooling forging punching center is positioned, this device can the quick and simple center that must determine drift, ensure the forging of ring endoporus of fetal membrane forging and molding and the axiality of cylindrical, the machining accuracy that has improved product, reduces machine-finish allowance, has avoided different moulds to manufacture different location-plates, save manufacturing cost, shortened the production cycle.In addition, positioner shifting out in process behind location do not need to make drift action, further ensures the positioning precision of drift.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
In figure: 1, crossbearer; 2, vertical frame; 3, elongated slot; 4, registration roller; 5, centralized positioning piece; 6, mould; 7, drift.
Detailed description of the invention
For further understanding summary of the invention of the present utility model, Characteristic, hereby exemplify following examples, and coordinate accompanying drawing to be described in detail as follows:
Refer to Fig. 1, a kind of loose tooling forging punching center positioning device, comprises two positioning units, and described positioning unit comprises that crossbearer 1 is connected and the vertical frame 2 vertical with described crossbearer 1 with described crossbearer 1 center, in the present embodiment, crossbearer 1 and vertical frame 2 are metallic plate integral type shaping by stock removal.The middle part of described vertical frame 2 is provided with along the elongated slot 3 of vertical frame 2 length directions, and the registration roller 4 that diameter is identical is installed respectively at the two ends of described crossbearer 1.The vertical frame 2 of described two positioning units is hinged by centralized positioning piece 5, and described centralized positioning piece 5 runs through the elongated slot 3 of the vertical frame 2 of described two positioning units.
Using method:
Registration roller 4 tops on two positioning units are pressed on the excircle of mould 6, and the residing position of centralized positioning piece 5 is mold center position.The Center-to-Center locating piece 5 of drift 7 is aligned.
Above-mentioned embodiment is only to functional descriptions of the present utility model; not design of the present utility model and scope are limited; do not departing under the prerequisite of the utility model design philosophy; various distortion and improvement that those skilled in the art make the technical solution of the utility model, within all dropping on protection domain of the present utility model.
