By adopting the technical scheme, the fastening taper key is very easy to put into and take out in die fastening, free adjustment can be performed in fastening, the die fastening taper key is large in adjusting range, simple in structure, easy to operate, good in fastening effect, safe and reliable, the service life of a fastening taper and the die is prolonged, and the economic benefit is remarkable.
Description
(1), technical field:
The invention belongs to fastener, be specifically related to a kind of mold fastening wedge key for forging hammers.
(2), background technology:
The mould that existing forging hammer is used is when fastening, the general wedge that adopts 45 steels to do of securing member, beat with hammer bang, wedge is thrown into carried out fasteningly in mould and the hammer anvil dovetail, this fastening method is unfavorable for adjusting operation, cause easily the damage of mould, fastening rear loosening fasteners is also very difficult, and in addition, the amplitude of regulating in fastening process is little, fastening effect is bad, has had a strong impact on die quality and service life.
(3), content of the present invention:
The object of the present invention is to provide a kind of mold fastening wedge key for forging hammers, the fastening wedge key of this mould is put into and takes out very easy when fastening to mould, energy free adjustment when fastening, the amplitude of adjusting is large, easy to operate, fastening effective, safe and reliable, fastening wedge key and mold use life-span have been improved, remarkable in economical benefits.
For achieving the above object, invented a kind of mold fastening wedge key for forging hammers, it is characterized in that: the fastening wedge key of described mould comprises the cuboid wedge key that is comprised of wedge I and wedge II, it is rectangle that the shape of wedge I and wedge II is the upper surface, two sides are leg-of-mutton triangle body, the cuboid key body center that is comprised of wedge I and wedge II is provided with oval-shaped centre bore, screw rod is installed in centre bore, screw rod is fixed on the wedge I by pin, the centre bore that the left end of screw rod passes wedge I left side stretches out, between the left side of the left end of screw rod and wedge key I, many butterfly pads are installed, right-hand member at wedge II is equipped with nut, nut is threaded with the right-hand member of screw rod, between the left end of the recess in the middle part of the described nut and nut, be provided with the tapering step, recess at the nut middle part is movably equipped with snap ring, inwall at wedge key II right-hand member centre bore is provided with draw-in groove, and described draw-in groove is corresponding with the position of snap ring.
In technique scheme, when needs are fastening, the nut of rotating screw bolt right-hand member, it is mobile in opposite directions to drive wedge I, wedge II, because wedge I, wedge II are triangular shaped, wedge I, wedge II under the pulling force effect of screw rod along the inclined-plane in the dovetail groove of mould and hammer anvil distending, make this mould assembly key swelling in mould, play fastening effect.Technical scheme of the present invention has the following advantages:
1, the cuboid wedge centre bore of wedge I and wedge II composition adopts U-shaped structure, can increase the amplitude of adjustment, and faying face adopts "＜" type cross section, has increased bonded area, increases Assembly stability.
2, left end and the screw rod between the wedge I at screw rod is fixed with a plurality of butterfly pads, can absorb the impulsive force that forging process produces, and prolongs wedge service life.
3, adopt band tapering ledge structure between the left end of the recess in the middle part of nut and nut, when nut moved to snap ring, stressed automatic swelling snap ring effectively prevented in the use procedure because shaking the excessive screw rod fracture obscission that causes.
4, the fastening wedge key of mould when fastening to mould, put into and take out very easy, can free adjustment when fastening, simple in structure, easy to operate, fastening effective, improved assembly key and mold use life-span.
(4), description of drawings:
Fig. 1 is the schematic appearance of a kind of mold fastening wedge key for forging hammers of the present invention;
The structural representation of wedge I and screw rod among Fig. 1 of Fig. 2;
Fig. 3 is the A-A cutaway view of Fig. 1;
Fig. 4 is the structure enlarged drawing at B place among Fig. 1;
Fig. 5 is the structure enlarged drawing at C place among Fig. 1.
(5), the specific embodiment:
Below in conjunction with accompanying drawing a kind of mold fastening wedge key for forging hammers of the present invention is described in further detail.
By Fig. 1, Fig. 2, Fig. 3, Fig. 4, Fig. 5 as seen, a kind of mold fastening wedge key for forging hammers of present embodiment is assemblied in hammer anvil dovetail groove place, is used for the locking forging mold.The fastening wedge key of this mould comprises wedge I 1, wedge II 2, screw rod 3, butterfly pad 5 and nut 6, in the present embodiment, wedge I 1 and wedge II 2 are metal material and make, it is rectangle that the shape of wedge I 1 and wedge II 2 is the upper surface, two sides are leg-of-mutton triangle body, wedge I 1 and wedge II2 form a cuboid wedge key altogether, inside center at wedge I 1 and wedge II 2 is provided with " U " shape groove, like this, the center of the cuboid key body that wedge I 1 and wedge II 2 form has altogether just formed oval-shaped centre bore, in an embodiment, the centre bore of the wedge key that wedge key I 1 and wedge key II 2 form adopts U-shaped structure, rather than circular, can increase the amplitude of adjustment, faying face adopts "＜" type cross section, increase bonded area, increased Assembly stability.
Be fixed with screw rod 3 in the oval-shaped centre bore of cuboid key body, screw rod 3 is fixed on the wedge I 1 by pin 4, prevents bolt rotary.The left end of screw rod 3 pass wedge 1 the left side centre bore and from centre bore, stretch out, between the left end of screw rod 3 and wedge I 1, be fixed with many butterfly pads 5, in the present embodiment, fix 9 dish-shaped pads 5 at the left end of screw rod 3, the material spring steel, per 3 one group stacks in the other direction, can absorb the impulsive force that forging process produces, and prolongs wedge key service life.Right-hand member at wedge II 2 is fixed with nut 6, nut 6 is threaded with the right-hand member of screw rod 3, between the left end of the recess at nut 6 middle parts and nut 6, be provided with the tapering step, recess at nut 6 middle parts is movably equipped with snap ring 7, inwall at wedge II 2 right-hand member centre bores is provided with draw-in groove 8, draw-in groove 8 is corresponding with the position of snap ring 7, in the present embodiment, recess at nut 6 middle parts adopts band tapering ledge structure, when nut moves to jump ring, stressed automatic swelling snap ring 7 effectively prevents in the use procedure because shaking the excessive snap ring that causes 7 obscissions.
Adopt technical scheme of the present invention, when fastening to mould, put into and take out assembly key and be very easy to, energy free adjustment when fastening, the amplitude of adjustment is large, simple in structure, easy to operate, fastening effective, safe and reliable, improved assembly key and mold use life-span, remarkable in economical benefits.
