A bar stock punching, cutting, sorting, and feeding device for stamping

Abstract

A bar stock punching, sorting, and feeding device belongs to the technical field of stamping equipment. By setting up a sorting roller group, when there are a large number of bar stocks stored in the box, the sorting roller group can control the motor to drive the sorting belt to rotate, driving the bar stocks near the bottom to roll or vibrate in the box, preventing a large number of bar stocks from being squeezed and piled up in the box, resulting in the bar stocks getting stuck in the box. By setting up a pusher plate, the pusher plate can uniformly push the bar stocks in the box forward, neatly stacking the bar stocks in the box, preventing the phenomenon of material jamming during the movement of the bar stocks. By setting up a sliding tray and a buffer guide plate, when the bar stocks fall from the feeding hole, the sliding tray and the buffer guide plate can make the bar stocks in a rolling state before entering the box, so as to realize the regular entry of the bar stocks into the box, prevent the bar stocks from entering the box in a disorderly manner, and thus increase the risk of material jamming.

Description

Technical Field

[0001] The present invention belongs to the technical field of stamping equipment, and particularly relates to a bar punching, sorting and feeding device for stamping. Background Art

[0002] Currently in the industry, the method of turning long bar materials into short bar materials is mainly completed by sawing with a sawing machine or punching with a punching machine. Since the above two processing procedures are very fast and efficient, and the bar materials after punching are stacked in a messy state, a conical hopper is usually installed at the outlet of the hopper. When storing bar materials in the conical hopper, due to the relatively large stacking density of the bar materials, problems such as bar extrusion, bar pressing, and blockage exist during the feeding process. Therefore, it is necessary to frequently stop the machine to sort out the messy bars, which seriously affects the production efficiency. Summary of the Invention

On each of the two material guiding side surfaces 9, there is an installation groove 10. In each of the two installation grooves 10, there is a set of sorting roller groups. The sorting roller group includes a motor 11 and two limiting plates 12. The motor 11 is arranged on the rear end face of the box body 8. The two limiting plates 12 are arranged at the positions corresponding to the installation grooves 10 outside the box body 8. Between the two ends of the two limiting plates 12, there is a rotating shaft 13 each. The driving shaft of the motor 11 is fixedly connected to the upper rotating shaft 13. A sorting belt 14 is connected between the two rotating shafts 13. The sorting belt 14 is arranged in the installation groove 10.

[0018] A pushing plate 15 is arranged inside the box body 8. On the rear end face of the outside of the box body 8, there are a plurality of sorting cylinders 16. The extending ends of the plurality of sorting cylinders 16 are all fixedly connected to the pushing plate 15. On the rear end face of the outside of the box body 8, there is an ejecting cylinder 17. The ejecting cylinder 17 is arranged at the bottom of the box body 8. The extending end of the ejecting cylinder 17 extends into the box body 8, and on the extending end of the ejecting cylinder 17, there is a top plate 18.

[0019] Principle of the present invention: In practical applications, the punching block 3 is installed in a punching press, and the bar stock is placed on the support block 4. The long bar stock is punched into short bar stocks by the punching press. After being punched, the short bar stocks will fall into the blanking hole 2, and the bar stocks falling out of the blanking hole 2 will roll on the material sliding plate. The rolling bar stocks roll out of the material sliding disk 6 and then fall on the buffer guide plate 20. The buffer guide plate 20 guides the bar stocks to the material guiding side surface 9 of the box body 8 and finally falls to the bottom of the box body 8. The bar stocks at the bottom of the box body 8 will be ejected from the discharge port 19 by the ejecting air cylinder 17;

[0020] When there are gradually more bar stocks accumulated in the box body 8, the bar stocks at the bottom will be pressed due to the gravity of the upper-layer bar stocks. At this time, the motors 11 in the two sets of stock arranging roller groups are controlled to rotate. The protrusions 23 on the surface of the stock arranging belt 14 drive the bar stocks at the bottom to roll, generating vibration, which facilitates the downward rolling of the bar stocks and facilitates the ejecting air cylinder 17 to eject the bar stocks. At the same time, the stock arranging air cylinder 16 can be controlled to extend, and the bar stocks are pushed forward by the top plate 18, neatly pushing the bar stocks to the front side inside the box body 8, which is convenient for the ejecting air cylinder to eject.

[0021] Finally, it should be pointed out that the above embodiments are only relatively representative examples of the present invention. Obviously, the present invention is not limited to the above embodiments and there can be many variations. Any simple modification, equivalent change and modification made to the above embodiments based on the technical essence of the present invention should be considered to fall within the protection scope of the present invention.
