The through hole falls into the blanking trough 35 below, which is convenient for waste recycling.

Working principle: when the automatic stamping equipment for electronic stamping parts production is in use, the parts to be stamped are first placed in the placement slot 34, and then the driving motor 19 is started, and the output shaft of the driving motor 19 drives the driving wheel 31 to rotate, and the belt drives Under the action, the driven wheel 30 is driven to rotate, thereby driving the second rotating shaft 39 and the first rotating disk 7 and the second rotating disk 24 fixed at both ends to rotate together.

When the first turntable 7 rotates, it will drive the first arc-shaped plate 6 to rotate through the sliding cooperation between the first slider 8 and the first arc-shaped groove 9, thereby driving the first swing link 4 along the axis with the first rotating shaft 5. The core rotates, and drives the first connecting rod 12 and the lifting block 13 to move downward, and then the lifting block 13 will drive the stamping column 14 at the bottom to move downward, and then pass the arc surface at the bottom of the stamping column 14 to place the to-be-stamped material in the groove 34. The parts are stamped and formed, and the basin-shaped cavity is first formed, and then when the first slider 8 rotates to the part that coincides with the arc track of the first arc groove 9, although the first slider 8 is along the first arc The inner wall of the groove 9 slides, but this time the first swing bar 4 has swung to the lowest position and remains in a stopped state.

When the stamping column 14 moves downward, it will drive the column 15 and the structure installed thereon to move downward together. Simultaneously, due to the cooperation of the limiting block 18 and the limiting groove 16, the position of the limiting block 18 on the limiting groove 16 will Sliding in the vertical groove, when the electromagnet pressing plate 27 first contacts with the workpiece to be stamped, with the movement of the cylinder 15, the electromagnet pressing plate 27 will slide against the telescopic rod 28 and slide into the installation hole 32, and at the same time the spring 33 will be compressed, and the spring will The elastic force of 33 can play a preloading effect on the stamping parts, which can prevent the stamping parts from being offset when the stamping column 14 stamps it, thereby improving the accuracy of the stamping column 14 when stamping. When the stamping column 14 is downward After the stamping part is stamped and formed, the limit block 18 also moves to the end of the vertical groove of the limit groove 16, and contacts the slope of the elastic wedge 36 and retracts against the elastic wedge 36, so that the limit block 18 crosses the elastic Wedge 36, and contact with one of the touch switches 37, then the electromagnet pressing plate 27 can be started by circuit control, so that the electromagnet pressing plate 27 is energized and the stamping parts to be stamped are adsorbed and fixed, and the electromagnet pressing plate 27 will also act on the telescopic rod 28 Perform magnetic adsorption, and then the telescopic rod 28 will be adsorbed and fixed with the iron block 38, and at this time, the telescopic rod 28 and the iron block 38 are equivalent to a fixed connection.

At the same time, when the second turntable 24 rotates, the sliding cooperation between the second slider 26 and the second arc groove 40 will drive the second arc plate 25 to rotate, thereby driving the second swing bar 23 to swing. The arc face of the two arc-shaped plates 25 faces opposite to the arc face of the first arc-shaped plate 6, and the motion track of the second slide block 26 partially overlaps with the arc track of the second arc-shaped groove 40, so when the first arc-shaped plate 6 When the slide block 8 drives the first fork 4 to swing, the second fork 23 is in a stopped state. At this time, the second slider 26 will drive the second swing rod 23 to swing through the sliding cooperation with the second arc-shaped groove 40, thereby driving the second connecting rod 21 and the installation slider 22 along the installation chute 20. The inner wall slides downwards, and then drives the punching pipe cutter 29 installed at the bottom of the slide block 22 to move downwards, thereby punching the center of the stamped part of the formed basin-shaped cavity, and because the second slide block 26 and the second The arc surface of the arc groove 40 cooperates to make the second swing bar 23 have an acceleration effect while swinging, so that the punching pipe knife 29 can be punched cleanly, which can reduce the burrs at the punching place and improve punching effect.

After the punching is completed, as the second rotating shaft 39 continues to rotate, it will drive the first swing bar 4 and the second swing bar 23 to swing upwards, thereby driving the lifting block 13 and the installation slide block 22 to move upwards for reset. When moving, it will drive the cylinder 15 to move upward together. At this time, because the electromagnet pressing plate 27, the telescopic rod 28 and the iron block 38 are magnetically adsorbed and fixed, it can prevent the electromagnet pressing plate 27 from pressing the stamped part due to the elastic force of the spring 33. Ejection, stamping parts can move upward together with electromagnet platen 27 like this, thereby disengage from placement groove 34, realize the demolding to stamping parts, when cylinder 15 moves upwards simultaneously, at this moment in the limit of elastic wedge 36 Under the action of position, the limit block 18 will slide along the inner wall of the limit groove 16, thereby driving the cylinder 15 to rotate, thereby driving the electromagnet pressure plate 27 to rotate through the telescopic rod 28. contact, so along with the rotation of the electromagnet platen 27, the inner wall of the basin-shaped cavity of the stamping part can be polished, and the bottom end of the stamping column 14 can also be polished, which further improves the surface quality of the stamping part. When the stamping column 14 is relatively rotated, it can also overcome the tight force of the stamping part on the bottom of the stamping column 14, so that there is no force between the stamping part and the stamping column 14, and then as the cylinder 15 rises and rotates, the When the limit block 18 touches another touch switch 37, the electromagnet pressure plate 27 will be de-energized through circuit control, and at this time, the stamping part and the electromagnet pressure plate 27 will be unfixed, thereby falling, and the blanking after grinding is reached. Effect, release between telescopic rod 28 and iron block 38 simultaneously, under the elastic force effect of spring 33, complete the pull-down reset of telescopic rod 28 and electromagnet platen 27, have finished the process of stamping and punching so far.

Although the embodiments of the present invention have been shown and described, those skilled in the art can understand that various changes, modifications and substitutions can be made to these embodiments without departing from the principle and spirit of the present invention. and modifications, the scope of the invention is defined by the appended claims and their equivalents.
