Description
Technical field
Material device is pushed using weight, and in particular to swing type riveting device the present invention relates to a kind of.
Background technology
At present, riveting processing technology in meal metalworking oneself through extensive use, riveting type is also more, mainly passes through profit
Two or more parts are connected as an entirety with rivet or are pressed on part or one kind of rivet coating nut etc.
Connection method.
Riveting as one generally be fixedly connected with mode, multiple fields have been widely applied to, such as sheet metal component
Riveting, the riveting of leaf springs of car, scissors, the riveting of pliers, bridge construction riveting etc.；In order to meet the market demand, on the market
There is a large amount of riveting set, mainly two major class of riveting set including revolving riveting set and pressing type.
Now the riveting set of the riveting sheet metal component of generally existing is revolving riveting set on the market, the structure of device
Rack, bull stick, punch-pin and cavity plate are generally comprised, bar rotation is connected in rack, and punch-pin is fixed on bull stick, and cavity plate is fixed on
In rack, cavity plate is located on the swinging track of punch-pin；In actual use, bull stick is driven by motor, and rivet is put on cavity plate, recessed
The sheet metal component to be riveted is put into below mould, bull stick rotary oscillation is controlled using motor, bull stick drives punch-pin rotary oscillation, punch-pin with
Cavity plate contacts and rivet is driven into sheet metal component connecting hole or is squeezed into thin plate sheet metal component, completes riveting process.
Above device there are the problem of be：1st, when motor drives bull stick, because motor link position is fixedly connected for bull stick
Main shaft on, punch-pin is then connected to the one end of bull stick far from main shaft, so according to torque formula, punch-pin rotation, effect vector compared with
Long, riveting impact force is then smaller, during riveting, it is easy to because the deficiency of rivet force causes relatively loosening for rivet, even
Riveting failure；2nd, when motor drives punch-pin to squeeze into rivet, since punch-pin is by the reaction force of moment, it will punch-pin is made to have phase
The trend of the movement of negative direction, punch-pin will have the tendency that opposite direction moves by main shaft motor, and motor is in rotating forward
When by one reversion power, it will certain injury is caused to motor, reduces the service life of motor.
Invention content
The invention is intended to provide a kind of swing type riveting device for ensureing riveting quality.
Swing type riveting device in the present invention, including rack, bull stick, punch-pin and cavity plate, bar rotation is connected to rack
On, punch-pin is fixed on bull stick, and cavity plate is fixed in rack, and cavity plate is located on the swinging track of punch-pin, and punch-pin is rotatably connected on
On bull stick, blade is fixedly connected on punch-pin, bar rotation, which is connected at the position of rack, is connected with torsional spring, and bull stick is far from cavity plate
Beater mechanism is connected in the rack of one side, the beater mechanism includes hopper, pushing block, support tube and cylinder, and support tube is fixed
In rack, hopper is connected with support tube, and fire element, the one end of support tube far from hopper and bull stick phase are loaded in hopper
It supports, slidably connects pushing block between support barrel at hopper outlet, pushing block is connected with the output rod of cylinder, pushing block and bull stick
Between support tube on be provided with trepanning, the wedge surface pressing plate across support tube is slidably connected in trepanning, the wedge surface of pressing plate is arranged on
In support tube and wedge surface tilting down from pushing block to bull stick direction, the first spring, bull stick are connected between pressing plate and support tube

The discharge hole being opened in rack is connected with, second spring is connected between impact block and support tube.
The present invention technical principle be：Rivet is put into cavity plate, fire element is put into hopper, starts cylinder,
Cylinder pulls pushing block move to far from the direction of pressing plate, and fire element is entered in support tube, then by cylinder control pushing block to
It is moved close to the direction of pressing plate, pushing block will push fire element to enter in pressing plate, due to being provided with wedge surface on pressing plate, draw
Fiery element will be successfully between pressing plate and support barrel hole penetrate, and move upwards pressing plate, pressing plate and support tube it
Between be connected with the first spring, pressing plate will compress fire element, detonating power supply excitation fire element, and fire element generates shock wave punching
Hit impact block, impact block will move to the direction close to bull stick, and impact block will hit bull stick, after by bull stick reaction force with
The effect of the elastic force of second spring will reset to initial position, and bull stick will drive punch-pin to be swung to cavity plate, on punch-pin
Blade will be rotated by the effect of air drag, and blade rotation will drive punch-pin rotation, and punch-pin will rotatably hit rivet, and
Rivet is driven rotatably to be driven into sheet metal component connecting hole or squeeze into thin plate sheet metal component, completes riveting process.
Then bull stick will be resetted by the reaction force of cavity plate and the elastic force of torsional spring, then control cylinder promotion next
Below fire element to pressing plate, a upper fire element will be pushed to by next fire element in material transport hole, and fallen from trepanning
Enter to discharge hole, be discharged to engine body exterior.
Compared with prior art, beneficial effects of the present invention are：1st, using beater mechanism directly to bull stick corresponding punch-pin
Position exerts a force, it is ensured that the impact force of punch-pin riveting can be such that rivet is more successfully driven into sheet metal component riveted holes；2nd, punch-pin
When squeezing into rivet, punch-pin by moment reaction force, it will make punch-pin that there is the movement of opposite direction, contribute to punch-pin
It resets；3rd, blade drives punch-pin rotation, and punch-pin drives rivet rotation ground nail to enter in sheet metal component, and rivet rotation matches with high speed impact
Close, pivoting friction destruction can be carried out to sheet metal component connecting hole hole wall or thin plate so that sheet metal component connecting hole be more easy to be expanded or
Person causes thin plate sheet metal component to be more easy to by holes, so as to which the riveting for being more conducive to rivet enters.
As the further preferred scheme of swing type riveting device, cavity plate is bonded with cushion rubber bumper close to one end of punch-pin.
When cushion rubber bumper can make punch-pin shock cavity plate, play the role of buffering punch-pin, reduce the effect of impact between punch-pin and cavity plate, from
And extend the service life between punch-pin and cavity plate.
As the still more preferably scheme of swing type riveting device, pushing block is equipped with to cylinder direction upward from pressing plate
Inclined inclined-plane, the top on inclined-plane are equipped with arc convex.Fire element is entered in the inclined-plane of pushing block, and fire element is by hopper
