Abstract
The utility model discloses a mold fastening wedge key for forging hammers, which comprises a first wedge, a second wedge, a screw stem, a plurality of disc washers and a nut. The first wedge and the second wedge are combined into a rectangular key, an elliptical center hole is arranged at the center of the key, the screw stem is mounted inside the center hole, the disc washers are mounted at the left end of the screw stem, and the nut is mounted is mounted at the right end of the second wedge and in threaded connection with the right end of the screw stem. According to the technical scheme, the fastening wedge key can be pushed in and out quite easily when used for fastening the mold, can be adjusted freely within a large range, and is simple in structure, easy to operate, fine in fastening effect, safe and reliable, and evident in economic benefit, while both the service lives of the fastening wedge key and the mold are prolonged.
Description
(1), technical field:
The utility model belongs to fastener, is specifically related to a kind of forging hammer with the fastening wedge key of mould.
(2), background technology:
The mould that existing forging hammer is used is when fastening, and the wedge that securing member generally adopts 45 steels to do beats with the hammer bang; Wedge thrown into carry out fasteningly in mould and the hammer anvil dovetail, this fastening method is unfavorable for adjustment operation causing the damage of mould easily; Fastening back loosening fasteners is also very difficult, and in addition, the amplitude of in fastening process, regulating is little; Fastening effect is bad, has had a strong impact on die quality and service life.
(3), summary of the invention:
The purpose of the utility model is to provide a kind of forging hammer with the fastening wedge key of mould, the fastening wedge key of this mould mould is put into and is taken out when fastening very easy, can free adjustment when fastening; The amplitude of adjustment is big; Easy to operate, fastening effective, safe and reliable; Improved the service life of fastening wedge key and mould, remarkable in economical benefits.
For achieving the above object, utility model a kind of forging hammer with the fastening wedge key of mould, it is characterized in that: the fastening wedge key of said mould comprises the cuboid wedge key of being made up of wedge I and wedge II; It is that rectangle, two sides are leg-of-mutton triangle body that the shape of wedge I and wedge II is the upper surface; The cuboid key body center of being made up of wedge I and wedge II is provided with oval-shaped centre bore, and screw rod is installed in centre bore, and screw rod is fixed on the wedge I through 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, at the right-hand member of wedge II nut are installed, nut is threaded with the right-hand member of screw rod; Between the left end of recess in the middle part of the said nut and nut, be provided with the tapering step; Recess at the nut middle part is movably equipped with snap ring, on the inwall of wedge key II right-hand member centre bore, is provided with draw-in groove, and said draw-in groove is corresponding with the position of snap ring.
In technique scheme; When needs were fastening, the nut of rotating screw bolt right-hand member drove wedge I, wedge II and moves in opposite directions; Because wedge I, wedge II are triangular shaped; Wedge I, wedge II be distending in the dovetail groove of mould and hammer anvil on the inclined-plane, tension lower edge of screw rod, makes this mould assembly key swelling in mould, plays fastening effect.The technical scheme of the utility model has the following advantages:
1, the cuboid wedge centre bore of wedge I and wedge II composition adopts U type structure, can increase the amplitude of adjustment, and " < " type cross section has increased bonded area, and it is stable to increase assembling in the faying face employing.
2, on the left end of screw rod and the screw rod between the wedge I, be fixed with a plurality of butterfly pads, can absorb the impulsive force that forging process produces, prolong wedge service life.
3, adopt band tapering ledge structure between the left end of recess in the middle part of nut and nut, when snap ring moved, stressed automatic swelling snap ring effectively prevented in the use because of shaking the excessive screw rod fracture obscission that causes at nut.
4, the fastening wedge key of mould mould is put into and is taken out when fastening very easy, can free adjustment when fastening, simple in structure, easy to operate, fastening effective, the service life of having improved assembly key and mould.
(4), description of drawings:
Fig. 1 is the schematic appearance of a kind of forging hammer of the utility model with the fastening wedge key of mould;
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. 3;
Fig. 5 is the structure enlarged drawing at C place among Fig. 3.
(5), the specific embodiment:
Below in conjunction with accompanying drawing a kind of forging hammer of the utility model is done further explain with the fastening wedge key of mould.
Visible by Fig. 1, Fig. 2, Fig. 3, Fig. 4, Fig. 5, a kind of forging hammer of present embodiment is assemblied in hammer anvil dovetail groove place with the fastening wedge key of mould, is used to lock 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, and in the present embodiment, wedge I 1 is metal material with wedge II 2 and processes; It is that rectangle, two sides are leg-of-mutton triangle body that the shape of wedge I 1 and wedge II 2 is the upper surface, and wedge I 1 and wedge II2 form a cuboid wedge key altogether, is provided with " U " shape groove in the inside center of wedge I 1 and wedge II 2; Like this, wedge I 1 has just formed oval-shaped centre bore with the center of the cuboid key body that wedge II 2 forms altogether, in an embodiment; Wedge key I 1 adopts U type structure with the centre bore of the wedge key that wedge key II 2 forms; Rather than circular, can increase the amplitude of adjustment, faying face adopts " < " type cross section; Increase bonded area, increased assembling stability.
In the oval-shaped centre bore of cuboid key body, be fixed with screw rod 3, screw rod 3 is fixed on the wedge I 1 through pin 4, prevents that screw rod from rotating.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, at fixing 9 the dish-shaped pads 5 of 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, and 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, is provided with the tapering step; Recess at nut 6 middle parts is movably equipped with snap ring 7; On the inwall of wedge II 2 right-hand member centre bores, be 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 jump ring moved, stressed automatic swelling snap ring 7 effectively prevented in the use because of shaking the excessive snap ring that causes 7 obscissions at nut.
Adopt the technical scheme of the utility model, be very easy in that assembly key is put into and taken out to mould when fastening, can free adjustment when fastening, the amplitude of adjustment is big; Simple in structure, easy to operate, fastening effective; Safe and reliable, as to have improved assembly key and mould service life, remarkable in economical benefits.
