For this reason, online body utilize existing riveting equipment be used and improve the problem solving and remove rivet; As shown in Figure 1, riveting equipment forms primarily of U-shaped caliper 1, hydraulic jack 2, transiting rod 3, movable die 4 and fixing die 5; Movable die 4 coordinates with fixing die 5 and is pressed on workpiece 7 by rivet 6.
Summary of the invention
The present invention proposes a kind of removal riveting device on commercial car vehicle frame production line, its objective is object riveting equipment being reached derivet.
In order to solve the problems of the technologies described above, technical scheme of the present invention is: a kind of removal riveting device on commercial car vehicle frame production line, comprise hydraulic-pressure riveting pincers, hydraulic-pressure riveting pincers are formed primarily of U-shaped caliper, hydraulic jack, hydraulic jack is fixed on the outside of U-shaped caliper left arm by oil cylinder seat, piston rod in hydraulic jack is connected with the transiting rod in U-shaped caliper left arm, and transiting rod the inner is provided with installing hole; It is characterized in that: also comprise pre-drift, derivet drift and die; Described die is made up of positioning sleeve and die guide holder, wherein die guide holder is threaded with U-shaped caliper right arm, the inner of die guide holder is provided with locating hole, rivet container cavity successively, the outer end of die guide holder is provided with gets rivet hole, locating hole, rivet container cavity, get rivet hole three and coaxially communicate successively, positioning sleeve is loaded on die guide holder by locating hole, positioning sleeve and pre-drift or derivet drift coaxially corresponding;
Described pre-drift is integrally formed structure by bullet drift, punch-holder shank, and wherein the small end face of bullet drift is plane, and planar diameter is slightly larger than rivet diameter;
Described derivet drift is integrally formed structure by punch-holder shank, transition part, drift successively, and wherein punch diameter is corresponding to rivet diameter;
During use, be first connected on transiting rod by pre-drift by drift locknut, pre-drift coordinates with die makes pre-drift rush flush riveting ailhead; Then, pre-drift is replaced with derivet drift, derivet drift coordinates with die makes derivet drift rush derivet in die.
Further improve technique scheme, the transition part of described derivet drift is provided with cannelure, safety shield and the cannelure clamping of installing safety shield.
To the further restriction of above-mentioned technical side, the positioning sleeve employing die steel material in described die is made, die guide holder adopts ordinary steel material to make.
Beneficial effect: the present invention has the following advantages:
1. die: be made up of positioning sleeve and die guide holder, wherein positioning sleeve is made up of mould, die guide holder is made up of ordinary steel material, thus reduces manufacturing cost; In use occur damaging, only need change positioning sleeve, enter one and lowly reduce cost; Die also plays guide function in derivet process, prevents riveting pincers and drift sideslip rivet axis, can have influence on except riveting quality, and prevent derivet drift from rupturing;
2. die guide holder: be mainly used in fixing die and receive being swept away the rivet come, each reception rivet be removed, prevent rivet not out, be provided with at die guide holder afterbody and get rivet hole, push rod conveniently releases rivet by getting rivet hole;
3. pre-drift: because manufactured head after rivet riveting is well that a semicircle is spherical, the manufactured head semicircle sphere substantial deviation rivet axis that particularly riveting is askew, radial load can be produced to drift, not rush flush riveting ailhead with pre-drift in advance, and directly adopt derivet drift to be easy to its collision cleft is broken;
4. safety shield: injure people for preventing drift collision cleft;
Summary, the movable die on riveting equipment and fixing die only need replace by the present invention, change the die removing rivet, pre-drift, derivet drift, just reach the object removing rivet, select the derivet drift of different-diameter according to the rivet of different-diameter; This achievement less investment, easy to operate, highly versatile, both handling safety, in turn ensure that product quality.
