Figure 2State (when the second rotating rod 28 moves to the right, the elastic force of the first spring 26 is not enough to drive the raw material plate 14 to retreat). When the second rotating rod 28 rotates, it will drive the raw material plate 14 to move forward, so that the raw material plate 14 steps forward one station. At the same time, the second rotating rod 28 will also push the sliding push rod 40, so that a group of clamping parts 37 in the blanking tube 41 fall into the pushing tube 36. When the pushing mechanism 3 moves to the right, the sliding push rod 40 pushes the clamping part 37 to be clamped into the punching hole 33 under the action of the second spring 38, so as to realize the automatic clamping of the clamping part 37.

[0024] The feeding mechanism 2 includes a first supporting leg 16, and the first supporting leg 16 is fixedly connected to the base plate 4, a sleeve tube 42 is fixedly connected to one side of the first supporting leg 16, a second rotating seat 49 is slidably connected inside the sleeve tube 42, a grinding rod 43 is rotatably connected to one end of the second rotating seat 49, the step of the grinding rod 43 has a certain taper, and there are grinding marks on the taper, a third spring 48 is fixedly connected between the second rotating seat 49 and the sleeve tube 42, a cross protrusion 45 is fixedly connected to one end of the grinding rod 43 away from the second rotating seat 49, and the cross protrusion 45 corresponds to the position of the cross slot 31, and both have a certain matching depth. One end of the first support leg 16 is fixedly connected to a push tube 36, the upper end of the push tube 36 is fixedly connected to a drop tube 41, one side of the push tube 36 is provided with a track groove 39, a sliding push rod 40 is slidably connected in the push tube 36, and the sliding push rod 40 is slidably connected to the track groove 39 (when the sliding push rod 40 is attached to the inclined block plate 44, an integer number of clamping parts 37 are installed in the push tube 36 to ensure that one clamping part 37 is pushed out each time and clamped into the punching hole 33, such as Figure 5 As shown), the second spring 38 is fixedly connected between the sliding push rod 40 and the first supporting leg 16, and a plurality of sets of clamping parts 37 are installed in the pushing tube 36 and the dropping tube 41; The upper end of the bottom plate 4 is fixedly connected with two groups of second supporting legs 17, and the upper ends of the two groups of second supporting legs 17 are fixedly connected with a limiting frame 15, and a through hole groove 47 is opened on the limiting frame 15, and a slide groove 46 is arranged on the limiting frame 15. A second notch groove 35 is arranged on one side of the clamping member 37, and the second notch groove 35 is adapted to the slide groove 46. The raw material plate 14 is slidably connected in the limiting frame 15, and there is a certain damping between the raw material plate 14 and the limiting frame 15. The upper end of the bottom plate 4 is fixedly connected with a fourth supporting leg 34, and the upper end of the fourth supporting leg 34 is fixedly connected with The inclined block plate 44, during the left movement of the ejector rod 21, the second rotating rod 28 will first drive the raw material plate 14 to step into one station, and then the ejector rod 21 rotates to punch out a new punching hole 33 on the raw material plate 14 (the raw material plate 14 is made of copper material, and the punching force required for punching is relatively small.), and at the same time, the grinding block 22 spins the clamping part 37 of the next station to make the clamping part 37 form a riveted connection, and then the grinding grooves on the ejector rod 21 grind the cutting edge of one side of the punched hole 33 (the movement of the ejector rod 21 is rotational advancement) to remove the burrs on one side of the edge of the punching hole 33. After the punching is completed (at this time, the cross slot 31 is rotated and pushed to match the cross protrusion 45), the electromagnet 32 ​​is started to absorb the grinding rod 43 (the grinding rod 43 is a metal magnetic material), and the cross protrusion 45 is inserted into the cross slot 31, so that the grinding rod 43 rotates with the push rod 21. In the front process of the right movement of the rotating shaft 20, the grinding rod 43 will be driven to rotate and move right, and the cutting edge on the other side of the punching hole 33 will be polished and burred. Then the electromagnet 32 ​​is turned off to complete the grinding of the burrs on the punching hole 33.

[0025] When doing specific work, Figure 3 This is the initial state and reference view. The blanking tube 41 and the push tube 36 are equipped with multiple sets of clamping parts 37. The raw material plate 14 is manually inserted into the limit frame 15. Four sets of process punching holes are pre-punched on the raw material plate 14 (the distance between the process punching holes is equal to the distance between the two adjacent punching holes 33, and the size of the holes is the same as the size of the clamping parts 37). The motor 5 is started. The motor 5 can drive the first rotating rod 8 to rotate counterclockwise through the motor shaft, thereby driving the T-shaped track frame 7 to move left and right. In this process, when the sliding seat 18 moves left and right, the rack 6 will slide back and forth, thereby driving the two sets of gears 19 to rotate, thereby driving the top rod 21 and the grinding block 22 to rotate. Initially, the sliding seat 18 moves to the left ( Figure 1 As a reference, the second rotating rod 28 is inserted into the punching hole 33, and then the second rotating rod 28 will abut against the inclined block plate 44 (contact with the inclined block plate 44), and the inclined surface of the inclined block plate 44 will cause the second rotating rod 28 to be inserted into the punching hole 33. Figure 1 Status Movement to Figure 2When the second rotating rod 28 rotates, the raw material plate 14 will be driven to move forward, so that the raw material plate 14 can be stepped forward by one station (the length between two adjacent stations is equal to the distance between two adjacent punching holes 33, which is not only equal to the vertical distance between the push rod 21 and the axis of the push tube 36, but also equal to the vertical distance between the axis of the push tube 36 and the abrasive block 22). At the same time, the movement of the raw material plate 14 will drive the front group of clamping parts 37 to slide from the second notch groove 35 into the slide groove 46 and slide to the corresponding position of the abrasive block 22 (with the second notch groove 35 being the first notch groove 35). Figure 3 For example, when the clamping member 37 is inserted into the punching hole 33, the clamping member 37 can only slide out from the second notch groove 35 in the direction of the punching hole 33, and will be blocked by the push tube 36 when moving in the reverse direction, which can prevent the raw material plate 14 from retreating, so that the raw material plate 14 can only move from the back to the front. ). Then the second rotating rod 28 will also push the sliding push rod 40, so that a group of clamping members 37 in the blanking tube 41 fall into the push tube 36. In this process, the push rod 21 punches a new punching hole 33 on the raw material plate 14.

[0026] After the punching is completed, the grinding grooves on the push rod 21 grind the edge of one side of the punching hole 33 to remove the burrs on the edge of the limiting notch groove 30. At the same time, the grinding block 22 spins the clamping piece 37 of the next station to make the clamping piece 37 form a riveted connection. The electromagnet 32 ​​is started to adsorb the grinding rod 43, and the cross protrusion 45 is inserted into the cross clamping groove 31, so that the grinding rod 43 rotates with the push rod 21. In the front part of the right movement of the rotating shaft 20, the grinding rod 43 will be driven to rotate and move right, and the other side of the punching hole 33 is grinded to remove burrs. After the burrs on the edge of the punching hole 33 are polished, the electromagnet 32 ​​is turned off to complete the grinding of the burrs on the punching hole 33. In the process of the pushing mechanism 3 moving right, the sliding push rod 40 pushes the clamping piece 37 to be clamped into the punching hole 33 under the action of the second spring 38, so as to realize the automatic clamping of the clamping piece 37.

[0027] During the whole process, when the pushing mechanism 3 moves to the left and slides on the inclined surface of the inclined block plate 44, the raw material plate 14 moves to realize the station change. When the pushing mechanism 3 moves to the left and drives the sliding push rod 40 to move to the left together, the automatic blanking of the clamping part 37 can be realized. At the same time, when the pushing mechanism 3 moves to the left and drives the sliding push rod 40 to move to the left together, the push rod 21 realizes the rotational blanking, and the grinding block 22 realizes the riveting of the clamping part 37 that has been blanked in the next station. When the pushing mechanism 3 moves to the right, the sliding push rod 40 pushes the clamping part 37 that has just been blanked under the action of the second spring 38, so that the rightmost clamping part 37 in the push tube 36 is clamped into the blanking hole 33, and at the same time, the grinding rod 43 rotates to the right to grind and remove burrs on the other side of the cutting edge of the blanking hole 33.

[0028] This not only realizes the stepping of the raw material plate 14 , but also realizes the spinning and punching of the punching hole 33 on the raw material plate 14 , and realizes the automatic blanking, clamping and riveting of the clamping part 37 .

[0029] Finally: The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
