Examples

Referring to fig. 1, the transferring device provided by the present invention includes a transferring structure 1, a pressing rod 2 and a pushing rod structure 3. The transfer structure 1 comprises a rotating rod 11, a torsion spring 12, a bearing plate 13 and a mounting seat 14, wherein the rotating rod 11 is rotatably connected to the mounting seat 14; the receiving plate 13 is fixedly connected to an upper portion of the rotating rod 11. The compression bar 2 is used for driving the rotating rod 11 to rotate, and then driving the bearing plate 13 to rotate. The torsion spring 12 is used for driving the rotating rod 11 to reset. The push rod structure 3 is used for pushing the workpiece to the bearing plate. When punching is carried out, the compression bar 11 drives the bearing plate 13 to rotate, so that the bearing plate 13 is far away from a workpiece, and the normal operation of a punching machine cannot be influenced; after the punching is completed, the torsion spring 12 drives the rotating rod 11 to reset, so that the receiving plate 13 is close to the workpiece, and the workpiece can be smoothly pushed to the receiving plate 13 by the push rod structure 3.

Specifically, the rotating rod 11 is generally a round rod, so that the rotating rod 11 can rotate smoothly on the mounting seat 14.

Further, the pressing rod 2 can be a single fixed rod connected to the punching machine, and the rotating rod 11 can be driven to rotate by extending and contracting. In the embodiment of this application, depression bar 2 can also fixed connection in the last pressure head 6 of punching machine, when last pressure head 6 pushes down, drives depression bar 2 downstream, when going up pressure head 6 and reseing, drives depression bar 2 upward movement.

Specifically, the vertical part of the pressure lever 2 is a plate-shaped structure, the lower part of the plate-shaped structure is obliquely arranged, and the width of the plate-shaped structure at the oblique position decreases from top to bottom. In order to enable the pressing rod 2 to drive the rotating rod 11 to rotate in the downward movement process, the upper part of the rotating rod 11 transversely extends to form an extending rod 111, and when the pressing rod 2 presses down, the pressing rod 2 is abutted to the extending rod 111. When the pressing rod 2 moves downwards gradually, the width of the part abutted with the extension rod 111 is gradually increased, so that the rotating angle of the rotating rod 11 is gradually increased, and the bearing plate 13 is further driven to be far away from the workpiece.

Preferably, the strut 2 abuts the extension rod 111 from the lowest end of the vertical portion.

When the pressure lever 2 returns upwards along with the upper pressure head 6, a torsion spring 12 is sleeved outside the rotating lever 11 so as to enable the rotating lever 11 to return. The outer wall of the rotating rod 11 is sleeved with a torsion spring 12, the upper end of the torsion spring 12 is fixedly connected with the rotating rod 11, and the lower end of the torsion spring 12 is fixedly connected with the mounting seat 14.

Referring to fig. 2-3, the receiving plate 13 is adjacent to the workpiece in the initial state of the torsion spring 12. When the compression bar 2 is pressed down to drive the rotating rod 11 to rotate, the bearing plate 13 is far away from the workpiece, so that the transferring device does not influence the stamping action, and the torsion spring 12 is twisted to store elastic potential energy; when the pressing rod 2 moves upwards along with the upper pressing head 6, the elastic potential energy is released, the torsion spring 12 drives the rotating rod 11 to rotate, and at the moment, the rotating rod 11 drives the bearing plate 13 to rotate, so that the bearing plate 13 is close to a workpiece.

Preferably, the receiving plate 13 is located above the torsion spring 12 such that the receiving plate 13 does not affect the rotation of the torsion spring 12.

Specifically, the bearing plate 13 is a v-21274with an upper opening, and the bottom surface of the bearing plate 13 is a bearing surface which is obliquely arranged. The side of the bearing surface close to the workpiece is higher, so that when the push rod structure 3 pushes the workpiece to the bearing surface, the workpiece can slide down along the inclined bearing surface.

In order to transport the work pieces, a roller table 4 is arranged below the discharge opening of the receiving surface (i.e. the lower end of the receiving surface). The work can be transferred to the next production process.

In order to prevent the work pieces from falling down the roller table 4, the roller table 4 comprises an inclined portion 41 and a horizontal portion 42. Wherein the inclined part 41 extends upwards from the horizontal part 42, and the upper end of the inclined part 41 is close to the discharge port and is positioned right below the discharge port, so that the workpieces sliding down from the bearing plate 13 can be timely borne by the roller way 4.

Preferably, the roller table 4 is located below the receiving plate 13, without affecting the rotation of the receiving plate 13.

Specifically, the pusher structure 3 includes a placing seat 31, an air cylinder 32, and a pushing plate 33. The cylinder 32 is fixedly connected to the upper surface of the placing seat 31, and the push plate 33 is fixedly connected to the output shaft of the cylinder 32. When the output shaft of the cylinder 32 is extended, the push plate 33 moves closer to the workpiece, and when the output shaft of the cylinder 32 is contracted, the push plate 33 moves away from the workpiece.

Preferably, the push plate 33 is a flexible plate to avoid scratching the workpiece.

As shown in fig. 2-3, the utility model also discloses a punching machine, including the above-mentioned transfer device, workstation 5, upper ram 6 and lower ram 7. The upper pressing head 6 and the lower pressing head 7 are fixedly connected to the upper surface of the workbench 5, and the upper pressing head 6 is positioned right above the lower pressing head 7. The pressure lever 2 is fixedly connected with the upper pressure head 6 and moves up and down along with the stamping of the upper pressure head 6.

Preferably, the mounting seat 14, the roller table 4 and the pusher structure 3 are fixedly connected to the work table 5 and are arranged beside the lower ram 7. And the height of the placing seat 31 is adjustable, so that the height of the air cylinder 32 is changed, and the push plate 33 can be always adapted to the height of the workpiece.

Fig. 2 is a structural diagram of the transfer device in a first state, in which the upper pressing head 6 is not pressed down, and the pressing rod 2 is far away from the extension rod 111. Fig. 3 is a structural schematic diagram of a second state of the transfer device, at this time, the upper pressing head 6 is pressed downward, the pressing rod 2 abuts against the extension rod 111, so that the torsion spring 12 stores energy, and the receiving plate 13 is far away from the workpiece.

Preferably, the press is controlled in operation by a controller. The sensor is arranged on the roller way 4, and after the sensor senses the workpiece, the punching machine starts to punch the workpiece for the next time, so that the workpiece on the bearing plate 13 can stably slide down.
