Abstract
The utility model relates to an industrial hydraulic riveting machine, comprising a cylinder body, a piston, a spring, a punching head, etc. The utility model has the advantages of simple structure, small size, portability and flexible operation. Under the control of the oil pressure, the punching head only makes once stroke to accomplish the high-quality riveting; the hydraulic riveting machine is suitable for riveting the metal by the hollow rivets with various different specifications.
Description
The portable hydraulic riveter of the utility model belongs to the class of jobs pressing equipment, and its purposes is to be used for the riveted joint of the semi-hollow metal rivet of various different sizes to various materials.
Rivet technology is needs to be movably hinged or the part of fastening connection, is riveted with the rivet that is fit to.Normally used rivet driver is to press with gas (oil) by gas (oil) cylinder pressure the rivet that is placed in advance on the required riveted joint object to be carried out bump, to finish riveted joint, because the rivet driver of this form repeatedly impacts rivet, so generation impact noise, and the flexural deformation phenomenon appears in rivet easily, both pollute the production environment in workshop, influenced riveting quality again.
In order to address these problems; adopt rotary extrusion type spinning or Swing rolling type to rivet now; HS-008A Swing rolling type rivet driver as the development of machine tool institute, Shanghai; though this dual mode can reduce noise; but it is inconsistent the tightness of damaging easily man-hour behind non-riveted joint face and the rivet to have occurred adding; rivet corresponding increase of time in addition, and different rivet length all to be adjusted the one stroke switch.
The objective of the invention is to provide a kind of improved portable hydraulic pressure rivet, it not only can reduce noise greatly, and can high efficiency, once finish riveting process in high quality.
Structure of the present invention as shown in Figure 1 and Figure 2.Soften rope 7, pulley 3 of rivet driver body 4 usefulness is suspended on the suspension bracket 1, by counterweight 2 balances (Fig. 2), rivet driver body position can be done arbitrarily angled adjustment or do the circumference rotation by action need, and can move up and down, as adding annex, the rivet driver body also can fixedly mount use.The rivet driver body is formed (Fig. 1) by parts such as cylinder body 7, piston 6, back-moving spring 5, guide pillar 1, stop nut 8, feather key 10, upper punch 3, following punch dies 2, wherein there are 90 jiaos of De Cone bodies at the low punch center, following punch die has the die cavity of manufactured head head, so that the location of semitubular rivet, the last rivet that needs the replacing drift just to can be used for different-diameter.Because rivet driver has adopted said structure, and adopted pressure to control the stroke mode, and the deformation force of the rivet of the same race of the same diameter of same material is identical, so need not do any adjustment to the rivet of the same race of different length just can be riveted, having overcome existing rivet driver all needs to adjust the shortcoming of travel switch to the rivet of the same race of every kind of length, thereby has improved production efficiency.
Application example of the present invention is with the semi-hollow irony rivet of 5 millimeters of diameters the metallic chair frame to be riveted.At first according to the length range of processed semitubular rivet, coarse adjustment stop nut 8 is fixed on a certain position of guide pillar 1 (Fig. 2) oil cylinder 7, connect power supply then, make two-bit triplet solenoid directional control valve 5(Fig. 2) in running order, at this moment pressure oil is transported to the cylinder body epicoele, make piston drive the descending impact semitubular rivet of upper punch, arrive the solid position of tubular rivet until upper punch, this rivet increases the reaction force of upper punch, oil pressure rises in the cylinder body thereby make, when pressure reaches pressure switch 6 or hydraulic system overflow valve 8(Fig. 2) the force value number set up in advance, pressure switch resets two three energising magnetic reversal valves, and at this moment oil circuit communicates with oil storage, under the effect of back-moving spring, it is up that piston drives drift, and realized the cycle of once riveting, and finished rivet.As adopt Swing rolling type rivet driver riveted joint metal frame, and need repeatedly adjust the riveted joint that whole metallic chair frame just can be finished in the travel switch position, this machine does not then need.
Major advantage of the present invention is owing to adopted pressure control backhaul mode, so after only need making stop nut of coarse adjustment, in situation about need not regulate, can finish at unit the riveted joint of the rivet of different length, damage easily in the riveted joint process non-riveted joint face and the diastrophic phenomenon of rivet have been eliminated, the tightness of having unified riveted joint, and can enhance productivity and quality, reduced noise pollution, also have simultaneously simple in structure, in light weight, easily make the advantage that expense is few.
