[0027] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0028] The utility model embodiment discloses a punching machine capable of automatically feeding materials.

[0029] Example 1

[0030] The utility model provides Figure 1-4 The punching machine with automatic feeding shown in the figure comprises two symmetrically arranged base frames 1, and the multiple base frames 1 are all arranged in a U shape. Two symmetrically arranged baffles 2 are fixedly arranged on the top of the two base frames 1, and two symmetrically arranged driving rollers 3 are rotatably arranged between the two baffles 2. Both ends of the roller wall of the driving roller 3 are fixedly sleeved with sprockets 4, and a chain 5 is commonly arranged between the multiple sprockets 4 on the same side. The outer walls of the two chains 5 are fixedly provided with multiple spaced support frames 6, and the end faces of the support frames 6 are fixedly provided with discharge rings 7. The side of the multiple discharge rings 7 away from the chain 5 is fixedly provided with a material suction magnet 20 embedded therein;

[0031] A mounting frame 8 is fixedly provided on the top of the rear baffle 2 , a hydraulic cylinder 9 is fixedly provided on the top of the mounting frame 8 , and an output end of the hydraulic cylinder 9 passes through the mounting frame 8 and is fixedly provided with a punch 10 .

[0032] Before punching the thin plate workpiece, multiple workpieces are placed on the discharge ring 7, and the workpieces are positioned by magnetic adsorption of the suction magnet 20 inside the discharge ring 7. Then, the driving roller 3 drives the multiple sprockets 4 to rotate, and the transmission of the two chains 6 can drive the multiple support frames 6 and the discharge ring 7 to be transmitted, so that the workpieces can be stably transported to the inside of the mounting frame 8, thereby starting the hydraulic cylinder 9, so that the punch 10 is driven to move downward and contact the workpiece, and the workpiece is punched. The continuous transmission of the chain 5 can continuously transport the workpiece, thereby reducing the time spent on workpiece transportation and improving the punching efficiency.

[0033] Example 2

[0034] Embodiment 2 is based on Embodiment 1, in order to drive the chain 5 to transmit when the punch 10 is moved upward for one punching, so as to complete the progressive conveying of the workpiece, as shown in FIG. Figure 1-3 As shown, a feeding punching mechanism for driving the sprocket 4 to rotate is provided on the back side of the mounting frame 8, and the feeding punching mechanism includes a rotating rod 11, which is rotatably arranged on the upper end of the back side of the mounting frame 8, and the rear ends of the rotating rod 11 and the driving roller 3 are fixedly sleeved with a pulley 12, and a belt 13 is commonly provided between the two pulleys 12. A one-way transmission mechanism for driving the belt 13 to drive is provided between the belt 13 and the hydraulic cylinder 9, and the one-way transmission mechanism includes a fixed block 14, and a sliding hole is opened at the lower end of the back side of the mounting frame 8, and the fixed block 14 A fixed sleeve is arranged on the upper end of the piston rod of the hydraulic cylinder 9 and is slidably arranged in the sliding hole. A fixed rod 15 is fixedly arranged on the back side of the fixed block 14. A ratchet 16 is rotatably sleeved on the rod wall of the fixed rod 15. The ratchet 16 is engaged with a plurality of push rods 17 arranged at intervals. The push rod 17 is fixedly arranged on the outside of the belt 13. A torsion spring 18 is sleeved on the rod wall of the fixed rod 15. The two ends of the torsion spring 18 are respectively fixedly connected to the fixed rod 15 and the ratchet 16. A limit plate 19 is contacted with the bottom of the ratchet 16, and the limit plate 19 is fixedly connected to the fixed block 14.

[0035] When the punch 10 moves downward, the hydraulic cylinder 9 drives the fixed block 14 to move downward and slide in the sliding hole. At this time, the ratchet 16 contacts the push rod 17 when moving downward, and cannot push the push rod 17 due to the torsion of the torsion spring 18. At this time, the punch 10 can move completely downward to punch holes. After punching, the punch 10 moves upward. At this time, the push rod 17 is supported by the limit plate 19 and pushes the push rod 17, so that the push rod 17 drives the belt 13 for transmission. At this time, the pulley 12 and the rotating rod 11 can be driven to rotate. At the same time, under the transmission of the pulleys 13 and 12, the driving roller 3 starts to rotate synchronously, and cooperates with the transmission of the chain 5 and the sprocket 4, which can drive multiple discharge rings 7 to move horizontally and complete the automatic transportation of workpieces, reducing manual intervention.

[0036] Example 3

[0037] Embodiment 3 is based on Embodiment 1-2 in order to complete the automatic feeding of workpieces without manually placing the workpieces one by one, such as Figure 1-2 As shown, a material discharge rack 21 is fixedly provided on the side of the baffle 2 away from the mounting frame 8, a rotating groove is opened at the bottom of the material discharge rack 21 close to the side of the baffle 2, two symmetrically arranged cross bars 22 are slidably penetrated on the side of the material discharge rack 21, and a push plate 23 is fixedly provided on one end of the two cross bars 22 close to the baffle 2, a spring 24 is sleeved on the rod wall of the cross bar 22, and the two ends of the spring 24 are respectively fixedly connected to the material discharge rack 21 and the cross bar 22, and two symmetrically arranged material blocking strips 25 are fixedly provided in the middle of the inner wall of the material discharge rack 21.

[0038] Before feeding and punching the workpiece, the stacked multiple thin plates are placed in the discharge rack 21. At this time, the thin plates are located between the push plate 23 and the stop strip 25 through the push of the spring 24. When the multiple discharge rings 7 are continuously transmitted, the discharge ring 7 can contact the outermost thin plate. At this time, it is pulled out from the discharge rack 21 under the adsorption of the suction magnet 20 and is placed on the discharge ring 7 for transportation. At the same time, under the support of the spring 24, the thin plate can always be in contact with the stop strip 25, so that the discharge ring 7 can contact and absorb the thin plate workpiece during rotation.

[0039] The above only describes some exemplary embodiments of the present invention by way of illustration. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
