Description
Technical field
The utility model relates to a kind of cold extrusion die, relates to a kind of half-finished cold extrusion die of band pad hexagonal locknut that is used for producing or rather.
Background technology
Band pad hexagonal locknut is used very extensive in industry.During processing belt pad hexagonal locknut, earlier raw material are processed to form the semi-finished product of band pad hexagonal locknut, again the double-ended pipe joint semi-finished product are carried out internal thread machining and form finished product.Half-finished production technology of present existing band pad hexagonal locknut has two kinds: one, carry out founding earlier and be cast as the pile tube blank, and then the pile tube blank is carried out the semi-finished product that machining becomes band pad hexagonal locknut.There is following defective in the mode that this kind produced band pad hexagonal locknut: blank becomes to be with the unnecessary material of will pruning in half-finished process of filling up hexagonal locknut in machining, and machining is consuming time many, influences production efficiency; Occur defectives such as sand holes, slag inclusion easily when raw material carry out the founding casting in addition, thereby influence product quality; Two, directly bigbore seamless steel pipe is processed, waste of raw materials is quite big like this, and machining is consuming time many, thereby has increased production cost, has reduced economic benefit.
Comprehensive above-mentioned reason, people consider to produce band pad hexagonal locknut semi-finished product with the mode of extruding, but the semi-finished product that hot extrusion is produced not only change in size are bigger, and the surface has one deck oxide skin, can not directly carry out internal thread machining, also need be through turning processing, production process is still more loaded down with trivial details like this.Therefore, in order to ensure the quality of products, to reduce the operation people and adopt the cold-stamped mode to produce semi-finished product.And the cold extrusion die that is used to produce band pad hexagonal locknut of prior art comprises die shank, cope match-plate pattern, upper die plate, upper mounted plate, die sleeve, bottom plate, counterdie backing plate and lower bolster.Described counterdie backing plate is fixed on the described lower bolster, described bottom plate is fixed on the described counterdie backing plate, described die sleeve is placed on the described bottom plate, described upper mounted plate is placed on the described die sleeve, described upper die plate is fixed on the described upper mounted plate, described cope match-plate pattern is fixed on the described upper die plate, and described die shank connects cope match-plate pattern, and is fixed on the described cope match-plate pattern.The endoporus of described die sleeve is the die cavity of mould.Described bottom plate is provided with lower punch and lead; described upper mounted plate is provided with punch, and the described punch of going up is provided with blind hole, and described lead connects lower punch and die cavity; its upper end sliding fit in described blind hole, and with the described punch sliding fit of going up.Though the cold extrusion die of this kind structure can processing belt the semi-finished product of pad hexagonal locknut, product stripping difficulty relatively just after the moulding, even can't the demoulding, thus cause production efficiency low.
The utility model content
The technical problems to be solved in the utility model is that a kind of cold extrusion die of band pad hexagonal locknut of the easy demoulding is provided.
Technical solution of the present utility model is, a kind of cold extrusion die with band pad hexagonal locknut of following structure is provided, it comprises die shank, upper die plate, upper mounted plate, die sleeve, bottom plate, goes up punch, lower punch and lead, it also comprises left and right sides supporting plate, described left and right sides supporting plate is separately positioned on described upper die plate, upper mounted plate and die sleeve left and right sides and fixes with described upper die plate, and described supporting plate and described die sleeve flexibly connect; Described upward punch is a stairstepping, described upper mounted plate be provided with described go up punch corresponding and with the shoulder hole of the die cavity coaxial line of die sleeve, described shoulder hole communicates with described die cavity, the described punch of going up is slidingly fitted in described shoulder hole and the die cavity, is provided with spring between the step of the step of described upward punch and the shoulder hole of upper mounted plate; It also comprises plays rod, and the described rod of beating connects described die shank and upper die plate and is slidingly matched with described die shank and upper die plate, and the described bottom face of playing rod pastes mutually with the top end face of last punch.
After adopting above structure, the cold extrusion die of the utility model band pad hexagonal locknut compared with prior art has the following advantages:
Because the supporting plate of the cold extrusion die of the utility model band pad hexagonal locknut and described die sleeve flexibly connect; described flexible connection is meant between supporting plate and the die sleeve and slides earlier; supporting plate drives the die sleeve motion more then; the described step-like punch of going up is slidingly fitted in the shoulder hole of described upper mounted plate; between the step of the step of described upward punch and the shoulder hole of upper mounted plate a spring is installed; the described rod and described die shank and upper die plate beaten is slidingly matched; therefore; after the semi-finished product moulding during die sinking; described cope match-plate pattern; the lifting that can under the drive of die shank, make progress of upper die plate and upper mounted plate; described supporting plate can also upwards promote under the drive of upper mounted plate; at this moment; just produce between described supporting plate and the die sleeve and slide; upper mounted plate will separate with die sleeve; will drive die sleeve when supporting plate rises to certain altitude upwards promotes; die sleeve lifting meeting separates with bottom plate; can make simultaneously to produce between semi-finished product and lower punch and the lead and become flexible; when treating that supporting plate rises to certain altitude; strike impacting rod; last punch can move downward under the promotion of playing rod; at this moment; semi-finished product can break away from die sleeve under the promotion of last punch; finish knockout course; the cold extrusion die of this kind structure makes the semi-finished product demoulding quite easy, thereby can increase work efficiency.
As a kind of improvement of the present utility model, described supporting plate and described die sleeve flexibly connect and are meant, be equipped with mounting hole on the supporting plate of the described left and right sides, the left and right sides of described die sleeve is equipped with pin, and described pin is slidingly fitted in the mounting hole of described supporting plate.This kind project organization is simple, realizes easily.
As another kind of improvement the of the present utility model, be provided with many thrust springs between described upper mounted plate and the described die sleeve, the lower end of described upper mounted plate is provided with the corresponding spring eye of quantity of quantity and described thrust spring, the upper end of described thrust spring is against on the roof of described spring eye, and the lower end of described thrust spring is spacing on described die sleeve.Owing to be provided with many thrust springs between described upper mounted plate and the described die sleeve, make and leave the space between the upper mounted plate and die sleeve after the mould die sinking, like this, in matched moulds, die sleeve can contact with bottom plate earlier, upper mounted plate contacts with die sleeve more then, makes that the workpiece in the preceding die sleeve of matched moulds can not ejected by last punch.
Also have a kind of improvement as of the present utility model, the lower end of described thrust spring is spacing to be meant that on described die sleeve described die sleeve is provided with alignment pin, and the lower end of described thrust spring is linked in outside the described alignment pin.This kind structure makes that the limit method of thrust spring lower end is simple in structure, realizes easily.
