Detailed Description

The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without any inventive effort, are intended to be within the scope of the utility model.

As shown in fig. 1-3, the embodiment of the utility model provides a feeding mechanism for automatic punching of U-shaped iron, which comprises a frame, wherein a motor is arranged on the frame and is connected with a vibrating disc 1, the uppermost part of the vibrating disc is in two cylindrical shapes, the diameter of an upper cylinder is larger than that of a lower cylinder, a cavity for accommodating a workpiece is formed in the middle of the cylinder, the vibrating disc 1 is driven to vibrate when the motor works, and the U-shaped iron workpiece is placed in the cavity in the middle of the vibrating disc 1. The material baffle is arranged along the ascending direction of the feeding track 4, the material baffle is used for limiting the number of workpieces passing through, the tail end of the feeding track 4 is connected with the material selecting track 7, the material selecting track 7 consists of separated arc material selecting sheets, the maximum size of the material selecting sheets is smaller than the diameter of U iron, the material selecting track 7 is connected with one end of the transition track 8, and the other end of the transition track 8 is connected with the discharging track 9. Along with the vibration of the vibration disc 1, the U-shaped iron is transported to the material selecting track 7 along the feeding track 4, passes through the transition track 8 after passing through the material selecting track 7, and is finally transported to the punching device through the discharging track 9.

For better transportation of the U iron, in the present application, a first striker plate 3, a second striker plate 5 and a third striker plate 6 are sequentially arranged in the feeding track 4 along the ascending direction. The height of the first striker plate 3 from the feeding track 4 is higher than the height of the second striker plate 5 from the feeding track 4, the height of the second striker plate 5 from the feeding track 4 is greater than the height of the third striker plate 6 from the feeding track 4, and the height of the third striker plate 6 from the feeding track 4 is greater than the thickness of one U iron. In the process of transporting the workpieces along the feeding track 4, a plurality of workpieces can be stacked together, firstly pass through the first baffle plate 3, and part of the workpieces are blocked by the first baffle plate 3 and fall into the cavity of the vibration disc 1 to enter the next vibration cycle; similarly, when passing through the second striker plate, part of the U-shaped iron accumulated on the track is blocked by the striker plate and falls out of the track. The third striker plate 6 at the tail end of the feeding track 4 is smaller than the thickness of two U-irons stacked up and down from the feeding track 4, and only one U-iron is allowed to pass through by the third striker plate 6 at a time.

The striker plate bolt passes through bar hole 2 and vibration dish 3 outer wall connection, and the bolt can reciprocate in the bar hole to this changes striker plate and highly apart from material loading track 4, thereby the U iron quantity of control single pass, and realizes the screening to the U iron of equidimension.

The tail end of the transition track 8 is communicated with the material cavity of the vibration disc 1, and part of U-shaped iron accumulated in the transition track 7 enters the discharging track 9 and the other part of U-shaped iron reenters the vibration disc 1.

The working process of the utility model is as follows:

pouring U-shaped iron into the vibration disc 1, conveying the U-shaped iron onto the feeding track 4 by the vibration disc 1, sequentially arranging a first striker plate 3, a second striker plate 5 and a third striker plate 6 along the ascending direction of the feeding track 4, controlling the passing quantity of the U-shaped iron by the striker plates, and limiting only one U-shaped iron to pass by the third striker plate 6; u iron is in a row and enters the material selecting track 7 through the third baffle plate 6, and as the arc material selecting sheets are small in size and are spaced, when the U iron with the downward opening enters the material selecting track 7, the U iron is close to the outer side of the track and cannot be supported along one side of the advancing direction, so that the U iron is suspended on the material selecting teeth sheets. Therefore, the U iron cannot stably advance, and then is extruded out of the material selecting rail 7 by the subsequently advancing U iron by means of the vibration disc 1 and the gravity of the U iron workpiece, and enters the vibration disc 1; conversely, the U-shaped iron with the upward opening can be supported at the bottom, and can smoothly enter the transition track 8 through the material selecting track 7, so that the U-shaped iron with the upward opening can be selected. The U iron with the upward opening enters the transition track 8 through the material selecting track 7, if the U iron is piled up on the transition track 8, one part of the U iron reenters the vibration disc 1 through the tail end of the transition track 8, and the other part of U iron enters the discharging track 9 and is conveyed to the punching device along the discharging track 9.

The foregoing description of the preferred embodiments of the utility model is not intended to be limiting, but rather is intended to cover all modifications, equivalents, alternatives, and improvements that fall within the spirit and scope of the utility model.
