Abstract

The utility model discloses an oval column core forming mould which comprises an upper mould body and a lower mould body. The upper mould body comprises an upper seat plate, an upper mould fixing sleeve, an upper mould pressing plate, upper mould padding plates and upper mould middle padding plates, wherein the upper mould padding plates are embedded into the upper seat plate and the upper mould fixing sleeve, and the upper mould middle padding plates are embedded into the upper mould fixing sleeve and the upper mould pressing plate. Columnar male moulds are installed in the upper mould middle padding plates. The lower mould body comprises a lower seat plate, an adjusting ring installed above the lower seat plate, a lower mould middle pad installed above the lower seat plate, and a lower mould pressing cover installed above the adjusting ring. The lower mould middle pad is arranged in the adjusting ring. A female mould is installed above the lower mould middle pad. The upper end of the female mould is embedded into the lower mould pressing cover. A mould core is embedded in the center of the female mould. A mould hole is formed in the center of the mould core. The lower ends of the columnar male moulds can extend into the mould hole in a corresponding mode. The space of the upper portion of the mould hole is larger than the space of the lower portion of the mould hole. The lower mould further comprises an ejecting rod sequentially penetrating through the lower seat plate and the adjusting ring and extending into the mould hole. The oval column core forming mould is convenient to machine and avoids wasting materials.

Description

Utility model content

The purpose of this utility model is to provide a kind of ovallized column core and goes out pin mould, easy to process, and has avoided waste of material.

For achieving the above object, the utility model provides a kind of ovallized column core to go out pin mould, comprise the upper die and lower die that cooperatively interact, described patrix comprises upper base plate, be arranged on described upper base plate below patrix fixed cover, be arranged on described patrix fixed cover below upper molded plate, be embedded in upper die plate in described upper base plate and patrix fixed cover, be embedded in backing plate in the patrix in described patrix fixed cover and upper molded plate, column punch is installed in backing plate in described patrix, described counterdie comprises lower seat board, be arranged in the adjustment ring of described lower seat board top and counterdie and pad, be arranged on the counterdie gland of described adjustment ring top, in described counterdie, pad is positioned at described adjustment ring, the top of padding in described counterdie is provided with die, the upper end of described die embeds in described counterdie gland, the center of described die is inlaid with core rod, the center of described core rod is provided with nib, the lower end of described column punch can correspondence be stretched in described nib, the space on the top of described nib is greater than the space of bottom, described counterdie also comprises push rod, described push rod passes successively described lower seat board and adjustment ring and stretches in described nib.

Preferably, in described counterdie, in pad, be provided with cushion block, described push rod is through described cushion block.

Compared with prior art, ovallized column core of the present utility model goes out pin mould employing column punch and nib corresponding matching is formable products, has replaced the mode of CNC milling machine processing, therefore without waste of material, and easy to process; Adopt embedded structure, thereby be convenient to processing and change consumable accessory.

By following description also by reference to the accompanying drawings, it is more clear that the utility model will become, and these accompanying drawings are used for explaining embodiment of the present utility model.

Accompanying drawing explanation

Fig. 1 is the schematic diagram that the utility model first set ovallized column core goes out pin mould.

Fig. 2 is the schematic diagram that the utility model second overlaps ovallized column core and go out pin mould.

The specific embodiment

With reference now to accompanying drawing, describe embodiment of the present utility model, in accompanying drawing, similarly element numbers represents similar element.

It is diel that ovallized column core of the present utility model goes out pin mould, has two covers.Please refer to Fig. 1, wherein first set mould comprises the counterdie and the patrix that cooperatively interact.Wherein, described patrix comprises upper base plate 1, be arranged on the patrix fixed cover 2 of described upper base plate 1 below, be arranged on described patrix fixed cover 2 belows upper molded plate 3, be embedded in upper die plate 4 in described upper base plate 1 and patrix fixed cover 2, be embedded in backing plate 5 in the patrix in described patrix fixed cover 2 and upper molded plate 3, column punch 6 is installed in backing plate 5 in described patrix.

Described counterdie comprises lower seat board 7, be arranged in the adjustment ring 8 of described lower seat board 7 tops and counterdie the counterdie gland 10 that pads 9, is arranged on described adjustment ring 8 tops, in described counterdie, pad 9 and be positioned at described adjustment ring 8, in described counterdie, pad 9 top die 11 is installed, the upper end of described die 11 embeds in described counterdie gland 10, described die 11 center is inlaid with core rod 12, the center of described core rod is provided with nib 12a, and the lower end correspondence of described column punch 6 stretches in described nib 12a.The space on the top of described nib 12a is larger than the space of bottom.Described counterdie also comprises push rod 13, and described push rod 13 passes successively described lower seat board 7 and adjustment ring 8 and stretches in described nib 12a.In described counterdie, pad in 9 and be provided with cushion block 14, described push rod 13 is through described cushion block 14.

Please refer to Fig. 2, the structure of the structure of the second mold and first set mould is roughly the same, difference is: in the patrix in the second mold, the center-hole diameter of backing plate 5 is greater than the center-hole diameter of backing plate 5 in the patrix in first set mould, therefore it is larger than being arranged on column punch 6 in first set mould to be arranged on column punch 6 in the second mold; The top of nib 12a in the second mold is larger than the top of the nib 12a in first set mould.

Ovallized column core of the present utility model goes out pin processing step:

(1), provide above-mentioned two molds.

(2), adopt heading machine to make after round metal material blank, make round metal material blank through annealing, sandblast, saponification, phosphatization processing.

(3), the round metal material blank obtaining in step (2) is placed in the nib 12a of die 11 of first set mould, utilize column punch 6 to exert pressure to round metal material blank, form forward extrusion, make round metal material blank enter mecystasis and along the die cavity of this mold be nib 12a flow, draw required blank shapes.

(4), by the blank obtaining in step (3) through annealing, sandblast, saponification, phosphatization processing.

(5), the blank obtaining in step (4) is put into the nib 12a of the second mold, utilize its column punch 6 to exert pressure to this blank, it is that nib 12a flows along the die cavity of this mold that formation forward extrusion makes blank, thereby makes required oval column.

The utility model has adopted the theory of plastic deformation of metal material, under the condition of room temperature, it is nib 12a that round metal material blank is put into the mold cavity being contained on forcing press, under powerful pressure and certain speed, by the effect of column punch 6, force round metal material blank to produce Plastic Flow, extrude oval column part.Having solved Elliptic Cylinder machine, to add difficulty large, the problem that waste of material is serious, and process simple and convenient; And employing embedded structure, be convenient to processing and change consumable accessory.

In conjunction with most preferred embodiment, the utility model is described above, but the utility model is not limited to the embodiment of above announcement, and should contains the various modifications of carrying out according to essence of the present utility model, equivalent combinations.
