Specific implementation mode
As Figure 1-Figure 4, pre-buried channel flow rivet rod riveting set, including crimping structure, the crimping structure include upper mold 2,
Lower die 17 and pedestal 10；It is equipped between upper mold 2 and lower die 17 and holds mechanism；The mechanism that holds includes supporting plate 15, the support
The centre of plate 15 is equipped with lower die cavity, and supporting plate both sides are equipped with and hold mechanism；The lower end of the lower die 17 is fixed on pedestal 10, on
End is placed in the lower die cavity, and can be slided above and below relatively with lower die cavity.The pedestal 10 is equipped with several pilot holes,
The lower face of the supporting plate 15 is equipped with and the matched several guide posts 14 of pilot hole, the guide post 14 dress
Enter in the pilot hole, bushing 13 is equipped in pilot hole.The mechanism that holds includes being arranged in the upper surface of supporting plate 15
Both sides are respectively equipped with along the symmetrical sliding block 6 of supporting plate median plane, and two opposite inside bottoms of sliding block 6 are respectively equipped with notch, this is lacked
Mouth is consistent with the shape of half of pre-buried channel flow；It is respectively equipped with baffle 18 at the both ends of supporting plate, which is equipped with mounting hole, institute
The both sides for the sliding block stated are respectively equipped with pull rod 19, and the other end of the pull rod 19 is installed with compression spring after mounting hole in the body of rod
16；The size of the notch is more than the size of the baffle.
The middle part of the upper surface of upper mold is equipped with die shank 1, and the middle part of lower face is equipped with briquetting 4；The both ends of upper mold are respectively equipped with
The lower end middle part of inclined wedge 3, the inclined wedge 3 is equipped with notch.
When riveting rivet rod, it is only necessary to pre-buried channel flow is placed in lower die, the rivet rod after heating is placed in pre-buried channel flow
In hole, by holding gear grips, moving down upper mold can rivet rivet rod on conduit, and easy to operate, riveting is efficient.
Notch on the inside of two sliding blocks constitutes notch in opposite directions, and lower die moves down, and inclined wedge squeezes sliding block and moves inward, and improves
Clamping degree of the sliding block to anchor pole so that rivet rod will not deform in riveting process, and after riveting, the spring on pull rod, which pulls, to be slided
Block moves outward, and convenient to install rivet rod next time, riveting speed is fast, and riveting effect is good.
The mechanism that holds further includes the inner slide 7 being arranged two 6 insides of sliding block, and one end of the inner slide 7 is in arc
Shape, the other end are installed with little spring 8, and spacer pin 5 is equipped between inner slide and sliding block.
When two arcuate structures move inward, the circle consistent with rivet rod is constituted, while clamping anchor pole limit,
Stress damage will not be caused to rivet rod.
The opposite medial surface of two sliding blocks is equipped with arcuate structure, and the arcuate structure longitudinal side and top are equipped with
Oblique angle.The oblique angle facilitates the movement of rivet rod, improves the docking operation between rivet rod and conduit.
The upper surface of the sliding block and the supporting plate is equipped with guide rail, and sliding block can be free to slide in guide rail.It leads
Rail structure can effectively reduce friction, improve operating efficiency, prolong the service life.
The lower end inside of the inclined wedge 3 is equipped with inner bevel, and the sliding block apical lateral is equipped with outer oblique angle, and described is interior
The inclined-plane at oblique angle and the plane at outer oblique angle are mutually parallel.When the oblique angle that inclined-plane is mutually parallel is convenient for riveting, upper mold and lower die it is fast
Speed contraposition.
During barricade is pushed for upper mold.Inclined wedge will not deform, and improve the compaction degree to sliding block.The pedestal lower end
Face is equipped with rubber pad 12, which is fixed on by bolt and clamping plate 11 on the pedestal, and rubber pad 12 plays pressure bullet
The effect of spring, the effect of barricade be prevent inclined wedge be bent outwardly deformation.
This hair designs a Special riveting mold, Special riveting mold be by hold mechanism and detent mechanism by conduit and
Rivet rod is fixed as one, then whole to move down, and generates a pressure to rivet rod head, rivet rod head is made to generate deformation, complete riveting.
When work, upper mold moves downward, and inclined wedge squeezes sliding block and moves clamping conduit and rivet rod inwards, later upper mold and fixture block
Continue to move downward as a whole, because lower die is to be rigidly fixed on lower template, during moving down, rivet rod by because
Pressure generates deformation, is finally completed riveting.
The manufacturing process of the present invention is as follows：
(1) lower die 17 being made according to conduit opening width, rivet rod deflection, 17 width of lower die and channel width are adapted,
The deflection that height generates after being riveted with rivet rod is consistent.
(2) supporting plate 15 is made, the notch to match with lower die 17 is provided among supporting plate 15, in order to which supporting plate 15 can be upper and lower
It is mobile, as shown in Figure 1.
(3) pedestal 10 is made, corresponding round hole is provided among pedestal 10, circular hole is packed into bushing 13, and guide post 14 passes through
Bushing 13,14 top of guide post are connected with supporting plate 15, and lower part is connected with clamping plate 11, and guide post 14 exceeds the height of pedestal 10
Deflection after being riveted more than rivet rod.
(4) thick rubber 12 is placed with below clamping plate, clamping plate 11, rubber 12 and pedestal 10 are connected by stay bolt to be connected in
One.
(5) certain activity, the deflection that activity is generated with rivet rod match under.Barricade 9 is bolted
On pedestal 10.The distance between two barricades 9 can just clamp two inclined wedges 3 in mold work, as shown in Figure 1.
(6) inner slide 7 is made, width is greater than rivet rod, one end tack, other end spill, spill and rivet rod diameter phase
Matching, and along corner cut under female end, as shown in Figure 4.
(7) sliding block 6 is made, the outer upper of left and right sliding block 6 is made as inclined-plane, and 6 compressive plane appropriate location of sliding block is internally
Digging, hole is inner small and outside big, constitutes inner slide hole, and specific size matches with inner slide 7.Also a size and limit are drawn in 6 top surface of sliding block
The hole that position pin 5 matches, and the hole penetrates inner slide hole.And sliding block clamp side dig out it is consistent with conduit and the half side shape of rivet rod
Space when two sliding blocks 6 clamp, just clamps conduit and rivet rod, as shown in Figure 3.
(8) little spring 8 is penetrated in inner slide hole, then inner slide 7 is put into inner slide, later wear spacer pin 5
Enter limit pin hole.Sliding block 6 is limited in using guide rail on supporting plate 15 after completion.Spring 16 passes through barricade 9 simultaneously, such as Fig. 3 institutes
Show.
(9) die shank 1, upper mold 2, inclined wedge 3 and briquetting 4 are made.The lower inside surface of inclined wedge 3 has parallel to each other with sliding block 6
Inclined-plane, and inclined wedge lower part is provided with groove, convenient for avoiding spring 16 during it is moved down.Above-mentioned 4 parts are connected as one
Body.
The present invention the course of work be：
When mold work, conduit enters along lower die 17 in mold, the head top to the upper surface of lower die 17 of rivet rod；Push riveting
Bar, until inner slide 7 just blocks the position of rivet rod.
Upper mold is run down, and left and right sliding block 6 starts movement inwards and clamps conduit and rivet rod.Briquetting 4 is whole to moving down simultaneously
Dynamic, when in left and right, sliding block 6 clamps, inclined wedge just wedges the gap between barricade 9 and sliding block 6 completely.
Then entire upper mold 2, sliding block 6 and supporting plate 15 continue integrally to move down, lower die 17 is to be rigidly fixed in lower bottom base 10
On, it is immovable, it will generate at this time and its Leading Edge Deformation is forced to rivet rod generation extruding force, and complete riveting.After completing primary riveting, weight
Multiple abovementioned steps, carry out next working cycles.
