the rivet pushing device is used for pushing rivets 14 fed from the rivet vibrating disk 15 to the right side of the positioning groove 5;

the riveting device is used for riveting the rivet 14 into the hinge joint of the outer page 22 and the inner page 4.

In this embodiment, outer page or leaf pusher include outer page or leaf push pedal 19, push away outer page or leaf cylinder 17, guide block 6 and briquetting 1, guide block 6 be located the front side of constant head tank 5, the front side of guide block 6 be equipped with outer page or leaf blanking position 20, outer page or leaf push pedal 19 locate outer page or leaf blanking position 20's front side, push away outer page or leaf cylinder 17 drive outer page or leaf push pedal 19 promote outer page or leaf 22 of unloading and be close to along guide block 6 interior page or leaf 4.

In this embodiment, a pressing block 1 is disposed above the guide block 6, and the pressing block 1 is located above the outer leaf 22 in the process of pushing the outer leaf 22 to slide along the guide block 6. The pressing block 1 can press the outer page 22 on the guide block 6 in the pushing process, and effectively prevents the outer page 22 from bouncing upwards in the pushing process of the outer page 22.

In this embodiment, the rivet pushing device includes a rivet feeding cylinder 16, a rivet feeding block 18, a rivet buffer plate 13, a rivet pushing rod 12 and a rivet pushing cylinder 11, the right sides of the outer leaf 22 and the inner leaf 4 are provided with a discharging channel 7, the rivet feeding cylinder 16 pushes the rivet feeding block 18 to move back and forth above the discharging channel 7, and a rivet hole 37 capable of accommodating the rivet 14 is arranged in the rivet feeding block 18. The inner diameter of a rivet hole 37 machined in the nail feeding block 18 is provided with an allowable linearity tolerance, once the range of the rivet is exceeded, the rivet cannot enter, the rivet push rod 12 cannot advance, and the structure can effectively avoid mixing unqualified rivets with poor linearity. The initiating terminal of rivet buffer plate 13 with rivet vibration dish 15 be connected, the end with rivet 14 neatly arrange and guide to discharging channel 7's front end, the end of rivet buffer plate 13 is equipped with rivet stopper 9, rivet push rod 12 from the side orientation rivet buffer plate 13's end, and by push away rivet cylinder 11 drive rivet push rod 12 with rivet buffer plate 13 terminal rivet 14 from the side propelling movement in the rivet hole 37 in the nail piece 18 of sending. Sometimes, the vibrating disc rivets 14 cannot keep up, in order to carry out stable production, the rivet buffer plate 13 is added, and 40 rivets 14 can be stored, so that the buffer time of the rivet vibrating disc 15 is kept enough, and the requirement of 35pcs/min can be met.

In this embodiment, the riveting device includes a hinge push rod 8, an oil cylinder 10, and a limit block 2; articulated push rod 8 be located discharging channel 7 with the relative one side of constant head tank 5, just articulated push rod 8 the direction of motion with constant head tank 5 direction set up unanimously, hydro-cylinder 10 drive articulated push rod 8 will send rivet 14 propelling movement in the rivet hole 37 of nail piece 18 to outer page or leaf 22 and the articulated department of interior page or leaf 4. It has been verified that a force of at least 3000N is required to drive the rivet 14 into the product, which is difficult to reach with a typical cylinder. The oil cylinder 10 is riveted by an external die for the first time, and the oil cylinder 10 is fixed to prevent the generated lateral force from causing play.

In this embodiment, the left end of the positioning groove 5 is provided with a limiting block 2. The arrangement of the limiting block 2 can effectively prevent the rivet 14 from being excessively riveted.

In this embodiment, an inner leaf 4 discharging push rod 3 is arranged below the inner leaf 4 and used for discharging after the riveting is finished.

In this embodiment, a top core 24 is disposed above the positioning groove 5, the top core 24 is fixed on a stop plate 33 of the punch press, a spring 26 is disposed between the top core 24 and the stop plate 33, a pressing block 25 is disposed on the front side of the top core 24, and a lower surface of the pressing block 25 is a slope surface with a high front and a low rear. The outer leaf 22 is pressed into the positioning groove 5 through the top core 24, generally speaking, the outer leaf pushing plate 19 can directly push the outer leaf 22 into the positioning groove 5 under the action of the outer leaf pushing cylinder 17, but if the outer leaf 22 is pushed in place, the outer leaf 22 cannot accurately fall into the positioning groove 5, and subsequent riveting work is inconvenient. At this time, the outer sheet 22 is pushed down by the top core 24, and the outer sheet 22 is surely pushed into the positioning groove 5. The inner leaf 4 is pressed into the positioning groove 5 through the upper stripping plate 35. The swaging block 25 plays a limiting role in the assembling process of the inner leaf 4, the outer leaf 22 and the rivet 14, so that the subsequent riveting work of the rivet 14 is facilitated, and the situation that the outer leaf 22 is tilted upwards when the rivet 14 is riveted is prevented. The upper die base 30 of the punch is also provided with a blanking convex die 27. The blanking convex die 27 is used for blanking the inner page 4 in the process of going down from the upper die.

As shown in the flow chart of fig. 4, in the present application, the material strip 35 is processed continuously through a pair of dies disposed on a punch press, and then the inner sheet 4 and the outer sheet 22 are formed finally through a plurality of punching processes.

Fig. 5 is a schematic view showing the connection between the inner sheet 4 and the outer sheet 22 of the finished workpiece according to the present invention.

The working principle of the utility model is as follows: the strip 35 is fed from the feeding end of the punch press, and through the continuous process shown in fig. 4, the outer sheet 22 workpiece is first blanked and dropped, and floats on the float block 21. The feeder feeds materials, and the material belt 35 pushes the outer pages 22 which are already blanked to the outer page blanking position 20, and the outer pages are blocked by the nail feeding block 18. The upper die descends, the rivet push rod 12 pushes the rivet 14 into the rivet hole 37 of the rivet feeding block 18 under the action of the rivet pushing cylinder 11, and then the rivet pushing cylinder 11 withdraws. The upper die continues to descend, the outer leaf pushing plate 19 pushes the outer leaf 22 into the position above the positioning groove 5 under the action of the outer leaf pushing cylinder 17, the pressing block 1 and the guide block 6 control the running direction of the outer leaf 22 to reach a specified position, and meanwhile, the rivet feeding block 18 feeds the rivet 14 into a specified position under the action of the rivet feeding cylinder 16, and the position is that the outlet of the rivet hole 37 is overlapped with the central position of the positioning groove 5. The upper die continues to descend and press the inner leaf into the positioning slot 5 while the upper stripper plate 34 of the punch press contacts the inner leaf 4. The core 24 presses the outer sheet 22 down and the outer sheet 22 is accurately pushed into the positioning groove 5. The upper stripper plate 34 compresses the inner sheet 4, and the pressing block 25 limits the outer sheet 22 (the compression is realized by the slope of the lower surface of the pressing block 25, so that the outer sheet 22 is prevented from tilting). The upper die continues to move downwards, the hinged push rod 8 enters the rivet feeding block 18 to push the rivet 14 into the inner leaf 4 and the outer leaf 22 under the action of the oil cylinder 10, the stop block 2 stops the rivet, and the riveting is completed. The upper die continues to descend, and the inner leaf 4 is cut off by the blanking convex die 27 located above. The upper die moves upwards, and the hinged push rod 8 returns under the action of the oil cylinder 10. The upper die continues to move upwards, and the push rod 3 and the nail feeding block 18 of the outer leaf 22 return. The upper die continues to move upwards, the feeder pushes the riveted finished product out of the die, the finished product falls into the discharge channel 7 to be discharged, and the die reaches the top dead center to be processed at one time.
