Description
Technical field
The present invention relates to a kind of removal riveting devices on production line.
Background technology
First, existing general removal rivet state of art
At present, largely using riveting process, this riveting process is easy to for cargo vehicle frame and other purposes carrying steel skeleton
Riveting is wrong and riveting is askew, solves the problem of that the rivet that riveting is wrong and riveting is askew exists using instruments such as sledgehammer, flat chisel and punching pines:
1st, the labor intensity of worker is added；
2nd, because of the impact by sledgehammer, the die that flat chisel and punching pin impact is easy to injure people, heavy then squeeze into human body internal injury
And the life to people；
3rd, because the impact by sledgehammer, flat chisel and punching pin are easy to hurt workpiece surface, product appearance quality is influenced.
2nd, exploitation removal rivet process unit background and condition
1st, in today of industrialization development, Time is money is exactly safely efficiency, is cost, but there is also another problem, rivetings
Wrong and riveting is askew and other issues to be and a small number of, and excessive input is also not real enough；
2nd, workpiece is all heavier, and it is all that in the production line, can resolve and leave nothing to be desired on assembly line to pinpoint the problems.
For this purpose, it is used and improves to solve to remove using existing riveting equipment in wire body
The problem of rivet；As shown in Figure 1, riveting equipment is mainly by U-shaped caliper 1, hydraulic cylinder 2, transiting rod 3,4 and of movable die
Fixed die 5 forms；Movable die 4 coordinates with fixed die 5 is pressed into rivet 6 on workpiece 7.
The content of the invention
The present invention proposes a kind of removal riveting device on production line, and the purpose is to reach riveting equipment except rivet
Purpose.
In order to solve the above-mentioned technical problem, the technical scheme is that：A kind of removal rivet dress on production line
It puts, is clamped including hydraulic-pressure riveting, hydraulic-pressure riveting pincers are mainly made of U-shaped caliper, hydraulic cylinder, and hydraulic cylinder is fixed on U by oil cylinder seat
On the outside of clamp body left arm, the piston rod in hydraulic cylinder is connected with the transiting rod in U-shaped caliper left arm, and transiting rod inner end is set
There is mounting hole；It is characterized in that：Further include pre- punch, except rivet punch and cavity plate；
The cavity plate is made of positioning sleeve and cavity plate guide holder, and wherein cavity plate guide holder is threadedly coupled with U-shaped caliper right arm, cavity plate
The inner end of guide holder is equipped with location hole, rivet accommodating chamber successively, and the outer end of cavity plate guide holder, which is equipped with, takes rivet hole, location hole, riveting
Nail accommodating chamber takes rivet hole three sequentially coaxially to communicate, positioning sleeve by location hole loaded on cavity plate guide holder, positioning sleeve with it is pre-
Punch or except rivet punch coaxially corresponds to；
The pre- punch is integrally formed structure by bullet punch, punch-holder shank, and the wherein small end face of bullet punch is plane, is put down
Face diameter is slightly larger than rivet diameter；
It is described except rivet punch is integrally formed structure, wherein punch diameter and rivet diameter by punch-holder shank, transition part, punch successively
Accordingly；
In use, being first connected to pre- punch on transiting rod by punch locknut, pre- punch makes pre- punch punching flat with cavity plate cooperation
Manufactured head；Then, pre- punch is replaced with except rivet punch, except rivet punch and cavity plate cooperation make except rivet punch punching is except rivet
To cavity plate.
Above-mentioned technical proposal is further improved, the transition part except rivet punch is equipped with installation safety shield
Annular groove, safety shield are clamped with annular groove.
Further restriction to above-mentioned technical side, the positioning sleeve in the cavity plate is made of die steel material, cavity plate
Guide holder is made of ordinary steel material.
Advantageous effect：The present invention has the following advantages：
1. cavity plate：It is made of positioning sleeve and cavity plate guide holder, wherein positioning sleeve is made of mold, cavity plate guide holder is by common iron
Material is made, so as to reduce manufacture cost；It damages in use, only needs to change positioning sleeve, low reduced into one
This；Cavity plate also acts as guide function during except rivet, prevents riveting pincers and punch sideslip rivet axis, influences whether except riveting matter
Amount, and prevent from being broken except rivet punch；
2. cavity plate guide holder：It is mainly used for fixed cavity plate and receives to be swept away the rivet come, receives a riveting being removed every time
Nail, prevents rivet from not coming out, and is equipped in cavity plate guide holder afterbody and takes rivet hole, push rod is by taking rivet hole to facilitate release riveting
Nail；
3. pre- punch:Because the good rear manufactured head of rivet riveting is that a semicircle is spherical, the particularly askew manufactured head semicircle sphere of riveting is seriously inclined
From rivet axis, radial load can be generated to punch, not rush flush riveting ailhead with pre- punch in advance, and directly used except rivet punch very
Easily break its collision cleft；
4. safety shield：To prevent punch collision cleft from injuring people；
Summary, the present invention need to only replace the movable die on riveting equipment and fixed die, change removal rivet cavity plate,
Pre- punch, except rivet punch, just achieve the purpose that remove rivet, rivet removed according to what the rivet of different-diameter selected different-diameter
Punch；This achievement less investment, easy to operate, versatile, i.e. safety also ensure product quality.
