Description

Technical Field

[0001] The utility model relates to the technical field of edge clamping and fixing for workpiece processing, in particular to a workpiece progressive forming edge clamping device. Background Art

[0002] The incremental forming process is based on the idea of ​​layered manufacturing and can achieve flexible processing of sheet metal without a mold or with the assistance of a simple mold.

[0003] The demand for high-performance, high-quality thin-walled sheet metal components has surged in the fields of new energy vehicles, biomedicine, aerospace, etc. Therefore, the incremental forming process has broad application prospects in the corresponding fields. Industrial robots have high flexibility. When single or dual robots are combined with incremental forming technology, the application scenarios of incremental forming can be further expanded, and the production efficiency and automation level of the forming process can be improved.

[0004] When using incremental forming technology to process workpieces, a clamping device is required to clamp the workpiece to prevent the workpiece from shifting during processing. However, the existing clamping process generally requires manual intervention to fix it, which is time-consuming and labor-intensive. The degree of automation of the clamping process needs to be further improved. Utility Model Content

[0005] The purpose of the utility model is to solve the problems raised in the above background technology, and then propose a workpiece progressive forming edge holding device.

[0006] The technical solution adopted by the utility model to solve its technical problems is:

[0007] A workpiece progressive forming edge clamping device comprises a processing table, on which a downward pressing telescopic component, an elongated hole and a liftable double side pressing component are arranged, the downward pressing telescopic component is connected to an edge clamping plate with an L-shaped main body shape and the vertical edge of the edge clamping plate can be lifted and lowered vertically along the elongated hole, the double side pressing component cooperates with the edge clamping plate to be used for stable clamping of the workpiece, and a six-degree-of-freedom robotic arm is arranged on one side of the processing table.

[0008] This device can effectively limit and press the workpiece automatically before the workpiece is subjected to incremental forming processing. After the pressing is completed, the position of the workpiece will not be shifted during the subsequent incremental forming processing. The pressing effect is good and the labor intensity of manual intervention and fixation is greatly reduced, and the degree of automation is significantly improved.

[0009] Furthermore, the downward-pressing telescopic assembly includes a mounting plate and a first cylinder. The mounting plate is arranged on the processing table, and the first cylinders are symmetrically arranged on the mounting plate. The two first cylinders are respectively connected to two symmetrically distributed edge pressing plates.

[0010] The above scheme can realize the clamping process of the workpiece by pressing down the telescopic component to drive the two edge clamping plates to move downward synchronously.

[0011] Furthermore, the double side pressure assembly includes an electric push rod, a lifting plate, a second cylinder, a side pressure plate and a guide rod. The electric push rods are symmetrically arranged on the front and rear side walls of the processing table. The electric push rods are connected to the lifting plate. The lifting plate is provided with a second cylinder and a storage groove is opened on the lifting plate. The second cylinder is connected to the side pressure plate matching the storage groove. The side pressure plate is symmetrically arranged with guide rods, and one end of the guide rod passes through the lifting plate and slides with the lifting plate.

[0012] The above scheme can further ensure that the stable edge pressing effect during the progressive forming process of the workpiece will not be offset by the double side pressure assembly, and at the same time, the placement orientation of the workpiece can be limited.

[0013] Furthermore, electromagnets are embedded in the horizontal edges of the edge pressure plate and the side pressure plates.

[0014] In the above scheme, after the horizontal edges of the side pressure plate and the edge pressure plate are in contact with the workpiece to achieve edge pressure, the controller immediately controls the electromagnet to energize, and then the workpiece can be further clamped and fixed. At this time, the workpiece will not have any positional deviation during the subsequent processing of the tool head module, and the progressive forming effect is better.

[0015] Compared with the prior art, the beneficial effects of the utility model are:

[0016] Compared with the existing technology, the present device can effectively limit and press the workpiece automatically before the workpiece is subjected to incremental forming processing. After the pressing is completed, the position of the workpiece will not be shifted during the subsequent incremental forming process. The pressing effect is good and the labor intensity of manual intervention and fixation is greatly reduced. The degree of automation is significantly improved. In addition, the workpiece does not need to be taken and placed manually. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] Further refinement of the embodiment of the present utility model is as follows: Figure 1 and Figure 3 As shown, the downward telescopic assembly includes a mounting plate 11 and a first cylinder 12. The mounting plate 11 is arranged on the processing table 1, and the first cylinders 12 are symmetrically arranged on the mounting plate 11. The two first cylinders 12 are respectively connected to two symmetrically distributed edge holding plates 13.

[0025] Further refinement of the embodiment of the present utility model is as follows: Figure 2 and Figure 3 As shown, the double side pressure assembly includes an electric push rod 21, a lifting plate 22, a second cylinder 23, a side pressure plate 25 and a guide rod 26.

[0026] It should be noted that the six-degree-of-freedom robot arm, the first cylinder 12, the electric push rod 21 and the second cylinder 23 are all electrically connected to the controller, which is not shown in the figure.

[0027] The workflow of this utility model:

[0028] First, use a six-degree-of-freedom robotic arm to place the workpiece that needs progressive forming on the processing table 1. The workpiece is not shown in the figure. During the placement process, the left and right sides of the workpiece are in contact with the vertical edges of the edge clamping plate 13. When the workpiece is placed, the controller controls the electric push rods 21 on the front and rear sides of the processing table 1 to move up synchronously so that the lifting plate 22 is higher than the upper surface of the processing table 1. When the lifting plate 22 rises to the height pre-set in the controller, the electric push rod 21 stops working. At this time, the controller controls the second cylinder 23 to work and then drives the side pressure plates 25 to move synchronously from both sides toward the workpiece. At this time, the edge clamping position of the workpiece can be accurately defined. After the definition is completed, the side pressure is kept clamped. Finally, the controller controls the second cylinder 23 to work and drive the side pressure plates 25 to move synchronously toward the workpiece from both sides. The cylinder 12 works synchronously to realize the synchronous downward movement of the two edge clamping plates 13. When the horizontal plate of the edge clamping plate 13 contacts the edge of the workpiece, the edge clamping of the workpiece can be fixed. After the edge clamping is completed, the tool head module can be used to perform the incremental forming process on the workpiece. When the workpiece completes the incremental forming process, the controller first controls the second cylinder 23 to contract so that the side pressure plate 25 moves into the storage groove 24, and then the electric push rod 21 contracts so that the lifting plate 22 moves to a height lower than the processing table 1. Finally, the controller controls the first cylinder 12 to extend so that the horizontal side of the edge clamping plate 13 is away from the workpiece. Then, the six-degree-of-freedom robot arm is used again to realize the unloading of the workpiece and a new round of unloading process.

[0029] Compared with the existing technology, the device can effectively limit and press the workpiece automatically before the incremental forming process. After the pressing is completed, the position of the workpiece will not be shifted during the subsequent incremental forming process. The pressing effect is good and the labor intensity of manual intervention and fixation is greatly reduced, and the degree of automation is significantly improved.

[0030] In some embodiments, electromagnets are embedded on the horizontal edges of the edge clamping plate 13 and the side pressure plate 25; the electromagnets are not shown in the figure; in this embodiment, after the side pressure plate 25 and the horizontal edges of the edge clamping plate 13 are in contact with the workpiece to achieve edge clamping, the controller immediately controls the electromagnet to energize, and then the workpiece can be further clamped and fixed. At this time, the workpiece will not have any positional deviation during the subsequent processing of the tool head module, and the progressive forming effect is better. It should be noted that the workpiece processed in this embodiment is a metal workpiece.
