detailed description

Below in conjunction with accompanying drawing, the utility model is described in further detail.

The specific embodiment is only an explanation of the utility model, and it is not a limitation of the utility model. Those skilled in the art can make modifications to the embodiment without creative contribution as required after reading this description, but as long as the utility model All claims are protected by patent law.

Embodiment: An automatic feeding punch press, as shown in FIG. 1 , includes a clamping part 1 for clamping a plate, a feeding platform 2 for placing a plate, and a punching device 3 for processing.

As shown in Figures 1 and 3, the end of the feeding platform 2 away from the stamping device 3 is provided with a concave mounting groove 4 along the horizontal direction, and a threaded rod 5 is installed in the mounting groove 4, and the end of the threaded rod 5 is rotatably connected. It is connected with a rotating drive member 52 that drives it to rotate, and a geared motor or a servo motor with forward and reverse functions can be used. A push plate 6 that is slidably connected to the upper opening of the installation groove 4 is provided above the threaded rod 5. On the push plate 6 There is also an abutting portion (not shown in the figure) that abuts against the threaded groove 51 on the threaded rod 5. The threaded grooves 51 are arranged in opposite directions and interlaced with each other, and the two threaded grooves 51 are arranged on the threaded rod. The two ends of 5 are connected.

When the threaded rod 5 rotates, the abutting portion of the push plate 6 moves along the threaded groove 51, but due to the limiting effect of the mounting groove 4, it can only move linearly along the mounting groove 4, and when the abutting portion moves along the When one thread groove 51 moves to the end, it can naturally transition to another thread groove 51 set in the opposite direction, and continue to make a linear motion opposite to the previous movement along the installation groove 4, thereby realizing the movement of the push plate 6 along the installation groove 4. The effect of linear reciprocating motion.

As shown in Figure 2, the upper surface of the feeding platform 2 is provided with a plurality of evenly arranged holes 8, and the holes 8 are all provided with balls 81 rolling and connected. When the balls 81 are placed in the holes 8, their tops are higher than The feeding platform 2 and the slot 8 are provided with a fixing piece 82 which engages with the ball 81 to prevent it from falling off. The middle of the fixing piece 82 is provided with a hollow part for the top of the ball 81 to pass through. When the plate is placed on the ball 81, the frictional force is greatly reduced, which facilitates the further transportation or movement of the plate.

As shown in Figures 1 and 4, the clamping part 1 includes a clamping head 12 and a sliding frame 11, the sliding frame 11 is provided with a connecting plate 13 perpendicular to the installation groove 4 along the horizontal direction, and the connecting plate 13 is equipped with a The transmission belt 7 in the rotating state is detachably connected to the connecting plate 13 by bolts, so that the distance between the transmission belt and the clamping head 12 can be adjusted to adapt to plates of different sizes.

As shown in Figures 1 and 4, the side of the transmission belt 7 away from the feeding platform 2 is provided with a side wall 75 integrally arranged with the transmission belt 7, the side wall 75 is in a vertical state and can be used to abut against the plate pushed by the push plate 6 To make it better fixed, the transmission belt 7 is also provided with a plurality of evenly arranged partition plates 71, the length direction of the partition plates 71 is consistent with the direction in which the installation groove 4 is offered, and every two partition plates 71 are formed for Grooves for securing the panels. The side of the partition plate 71 near the feeding platform 2 is set as a concave arc, and one end of the arc is arranged horizontally and at the same height as the feeding platform 2. Push down to move to the transmission belt 7, if it encounters the partition plate 71, it cannot enter the groove. At this time, the plate moves along the arc to the partition plate 71 and is erected on the partition plate 71, and follows the partition plate 71 Let's move forward together.

As shown in Figures 1 and 4, a baffle 21 is also provided on the feeding platform 2, and one end of the baffle 21 away from the clamping part 1 is fixedly connected to the feeding platform 2, and the other end of the baffle 21 extends to the partition. Above the arc portion of the plate 71, there is a gap between the bottom end of the baffle plate 21 and the upper surface of the feeding platform 2, and the gap is enough for the plates to pass through. When the board is erected on the partition plate 71 and continues to move forward, the board will abut against the baffle plate 21 and cannot continue to move forward until the partition board 71 breaks away from the board and the board falls into the groove, and on the transmission belt 7 Continue to move forward under the drive.

As shown in Fig. 1 and Fig. 4, the partition board 71 and the side wall 75 are slidably inserted to realize the adjustable number of partition boards 71, which is convenient for adjusting the size of the groove and meeting the requirements of boards of different sizes. The side wall 75 is provided with a through T-shaped slot 73, the side of the partition plate 71 is provided with a plug block 72 matched with the slot 73, and the top of the slot 73 is provided with a top for closing the opening. Brake plate 74, one end of brake plate 74 is hinged on one side of insertion slot 73 and the other end is fixedly connected to the other side of insertion slot 73 by bolts. When the brake plate 74 is fixedly connected to the top of the insertion slot 73 , it can prevent the insertion block 72 from detaching from the insertion slot 73 .

The working principle of this embodiment is: when the punch press is running, place the plate to be processed on the feeding platform 2, and because the ball 81 converts sliding friction into rolling friction, most of the friction is reduced and it is easy to move. The threaded rod 5 rotates under the driving of the rotating drive member 52, and then drives the push plate 6 to reciprocate linearly along the direction of the installation groove 4, and pushes the plate 6 to move towards the transmission belt 7 until it abuts against the side wall 75 of the transmission belt 7. The plate is in the groove and runs towards the clamping head 12 driven by the transmission belt 7 or the partition plate 71 until it reaches the position of the clamping head 12; , after encountering the baffle plate 21, the plate will fall into the next groove, thereby continuing to move forward in a horizontal state.
