Technical Field

[0001] The utility model relates to an extrusion processing device for producing arc-shaped plates, belonging to the technical field of arc-shaped plate production. Background Art

[0002] In the stamping equipment in the prior art, for curved plates or curved parts with curved lines, the stamping operation of the stamping equipment on the curved plates and the majority of the structural settings of the stamping equipment are relatively simple. The cold stamping of the curved plates can be completed by setting the punch device of the stamping equipment to an arc structure and the corresponding groove to an arc structure.

[0003] Patent number CN201820754000.4 discloses a device for cold stamping curved sheet metal parts. The device comprises a bottom stamping base and a stamping propulsion device positioned above the base. The device has a vertically downward-pointing propulsion head with a curved stamping punch mounted at its end. The stamping base is provided with a curved die groove that matches the shape of the curved stamping punch.

[0004] The current technical considerations are not comprehensive and have the following disadvantages: when stamping curved plates, stamping dies are required. If, in the specific production of the factory, the specifications of a certain type of curved plate may change after a period of production, a new mold needs to be opened, which undoubtedly increases the production cost. Especially in situations where the precision requirements of the curved plates are not high, it is completely unnecessary to open a new high-precision mold.

[0005] In order to solve one of the above problems, an extrusion processing device for producing curved plates is urgently needed. Utility Model Content

[0006] In view of the above deficiencies in the existing technology, the technical problem to be solved by the present invention is: how to achieve that each group of upper template monomers can be controlled to rise and fall through the template lifting drive mechanism corresponding to it, so that the curvature of the convex arc-shaped working surface formed by the combination can be adjusted as needed to produce arc-shaped plates with different curvatures. For this purpose, an extrusion processing device for arc-shaped plate production is provided.

[0007] The extrusion processing device for producing curved plates described in the present invention includes a base and a curved stamping punch mounting bracket and a lower die mounted on the base, and is characterized in that: a curved stamping punch that can move up and down relative to the lower die is mounted on the curved stamping punch mounting bracket through an upper die lifting drive mechanism, and the downward-pressed curved stamping punch cooperates with the lower die to bend the steel plate on the lower die into shape, and the curved stamping punch includes a plurality of groups of adjacently arranged upper die plates and a lifting frame connected to the upper die lifting drive mechanism, and a plurality of groups of die plate lifting drive mechanisms for driving the corresponding upper die plates to lift and lower are mounted on the lifting frame, and the bottoms of the plurality of adjacently arranged upper die plates are combined to form an outwardly convex curved working surface.

The existing power unit is used to drive the arc-shaped stamping punch downward, and the arc-shaped stamping punch presses down the steel plate on the lower die, and cooperates with the left and right extrusion rollers of the arc-shaped stamping punch mounting bracket to bend the steel plate on the lower die into an arc-shaped plate, thereby improving the forming efficiency.

[0009] Each group of upper template monomers can be controlled to rise and fall through the corresponding template lifting drive mechanism. By controlling the bottom of multiple groups of upper template monomers to rise step by step from the middle to both sides, the curvature of the convex arc-shaped working surface formed by the combination can be adjusted as needed to achieve the production of curved plates with different curvatures.

[0019] Turning on the servo motor and controlling its forward or reverse rotation drives the left and right steel plate support blocks toward or away from each other to adjust the spacing. The left and right extrusion rollers form a pair of rollers with adjustable spacing. By adjusting the spacing, the rollers can be matched to the convex curved working surfaces of different curvatures, enabling the production of curved plate workpieces of varying diameters and curvatures.
