Abstract
The invention discloses a pneumatic-control lower die of an automatic nail-delivering riveter. The pneumatic-control lower die of the automatic nail-delivering riveter comprises a die seat, a die core and a locating screw, wherein the die seat is internally provided with a die cavity in which the die core can stretch and contract up and down; the die seat is provided with a vent hole communicated with the die cavity; the vent hole is located at the lower part of the die core; the die core is hermetically matched with the inner wall of the die cavity; the pneumatic-control lower die has the following advantages that the die core is enabled to stretch and contract by virtue of air admission and air exhaust under the effect of compressed air instead of a spring; before riveting, the die core contracts in the die cavity so as to be prevented from colliding with a workpiece; when one workpiece has multiple to-be-riveted and one lower die is needed to be arranged at each to-be-riveted point, so that inconvenience is prevented from being brought to workpiece installation; at each riveted point, the die core does not generate a jacking force on the workpiece, and the workpiece does not deviate; during multipoint riveting, when included angles exist between center lines of two or more to-be-riveted holes of the workpiece, the die core can not interfere with the workpiece and can be directly arranged on a clamp.
Description
Technical field
The present invention relates to riveting equipment, refer to particularly a kind of gas control counterdie of automatic nail feeding riveting machine.
Background technology
Automatic nail feeding riveting machine is a kind ofly can automatically complete by mechanical device the automation riveting equipment that send rivet, conveying rivet, lays rivet and riveted joint, and its efficiency is the several times of common riveting equipment.
The riveting molding key of automatic nail feeding riveting machine is the counterdie of sectional die.The effect of counterdie is: core rod plays the effect of location through the riveted holes of workpiece, also plays the effect that guiding rivet enters riveted holes simultaneously.Core rod moves down into after bottom dead center with upper film and is combined into a complete mould, makes rivet moulding in its die cavity, completes riveted joint process.
Conventional counterdie is spring at present, as shown in Figure 1, comprise the set screw 3 of die holder 1, core rod 2 and die holder 1 bottom, in the die cavity 5 of die holder 1, be provided with spring 4, one end of spring 4 props up the upper surface of set screw 3, and the other end of spring 4 is enclosed within the middle part of core rod 2.In the time of riveting molding, as shown in Fig. 2 ~ 3, first workpiece 8 is placed on counterdie, upper film 10 is by rivet 9 to pressing down, and core rod 2 imports rivet 9 in the riveted holes of workpiece 8, moulding in the die cavity that rivet 9 forms at core rod 2 and die holder 1.Take off workpiece 8, core rod 2 stretches out under the effect of spring 4.Because the core rod of spring counterdie extends before riveted joint, easy and workpiece generation collision in the process of stretching out and shrinking.
In addition, in the time having multiple spot riveted joint on a workpiece, need to a counterdie be installed in each riveting point, the core rod of spring counterdie is easily installed and is produced inconvenience workpiece, and in the riveting point of having riveted, core rod has a jacking force to workpiece, makes workpiece produce skew.
Moreover, in the time that multiple spot is riveted, in the time there is angle between the center line that has two or more riveted holes on workpiece, while using spring counterdie, due to core rod and workpiece generation interference, and cannot directly be placed on fixture, need the more complicated clamp structure of design to use.
Summary of the invention
Object of the present invention will overcome the existing deficiency of prior art exactly, and the gas control counterdie of a kind of registration, automatic nail feeding riveting machine that operating efficiency is high is provided.
For achieving the above object, the gas control counterdie of the designed automatic nail feeding riveting machine of the present invention, comprise die holder, core rod and set screw, in described die holder, be provided with the die cavity stretching up and down for core rod, on described die holder, be provided with the passage being connected with die cavity, described passage is positioned at the below of core rod, and described core rod coordinates with the inner wall sealing of die cavity.
Preferably, described passage is arranged on the bottom of die holder side, and the top of described set screw is provided with positioning boss, and the upper surface of described positioning boss, higher than the upper wall surface of described passage, leaves gas passage between described positioning boss and passage.
Preferably, the outer ring of described core rod lower end and the inwall of die cavity are sealed and matched by sealing ring, and described set screw and die cavity contact-making surface are also provided with sealing ring.Like this, can increase the sealing at passage two ends.
Preferably, described set screw and die holder are bolted to connection.
Beneficial effect of the present invention is: gas control counterdie utilizes compressed air to substitute the effect of spring, by air inlet and exhaust, core rod is stretched out and retract.Compared with spring counterdie, gas control counterdie has following advantage:
1, core rod stretch out and shrink can by ventilation and exhaust control, before riveted joint, core rod can be contracted in die cavity, avoid and workpiece produce collision;
2, in the time having multiple spot riveted joint a counterdie to be installed in each riveting point on a workpiece, the flexible of gas control counterdie core rod can not installed and produce inconvenience workpiece, and in the riveting point of having riveted, core rod can not produce jacking force to workpiece, and workpiece can not be offset;
3, rivet in the time there is angle between the center line that has two or more riveted holes on workpiece at multiple spot, gas control counterdie is because core rod is flexible, and core rod can not produce and interfere with workpiece, can directly be placed on fixture.

Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the present invention is described in further detail.
Existing automatic nail feeding riveting machine spring counterdie shown in Fig. 1 ~ 3 has been done detailed introduction in background technology, repeats no more in this.
The gas control counterdie of the automatic nail feeding riveting machine shown in Fig. 4 ~ 5, comprises die holder 1, core rod 2 and set screw 3, is provided with the die cavity 5 stretching up and down for core rod 2 in die holder 1.Set screw 3 is fixedly connected with by bolt 8 with die holder 1.The bottom of die holder 1 side is provided with the passage 6 being connected with die cavity 5, and passage 6 is positioned at the below of core rod 2.The top of set screw 3 is provided with positioning boss 3.1, and the upper surface of positioning boss 3.1, higher than the upper wall surface of described passage 6, leaves gas passage between positioning boss 3.1 and passage 6.The outer ring of core rod 2 lower ends and the inwall of die cavity 5 are sealed and matched by sealing ring 7, and set screw 3 is also provided with sealing ring 7 with die cavity 5 contact-making surfaces.
The course of work of the present invention:
