s1, respectively installing an upper film 1 and a lower film 2 on an oil press; s2, fixing the double-curvature saddle-shaped plate raw material on a lower die pressing curved surface 16 of the lower die 2, and limiting the degree of freedom of the double-curvature saddle-shaped plate raw material by using spot welding; s3, starting an oil press to feed at uniform speed, enabling the upper die 1 and the lower die 2 to be close until the upper die pressing curved surface 9 and the lower die pressing curved surface 16 are formed and the double-curvature saddle-shaped plate raw material is pressed by applying force, keeping the pressing time for 3-5 minutes, S4, starting the oil press to control the upper die 1 and the lower die 2 to reset, separating the upper die from the lower die, taking down the double-curvature saddle-shaped plate finished product, and checking the finished product by using a wooden sample box. The curvature of the wooden sample box is in a standard shape, so that the check is convenient.
According to the double-curvature saddle-shaped plate pressing forming tool, when the tool is manufactured, the upper die substrate, the plurality of upper die transverse partition plates and the plurality of upper die longitudinal partition plates of the upper die are cut and prepared by the cutting machine, and the lower die substrate, the plurality of lower die transverse partition plates and the plurality of lower die longitudinal partition plates of the lower die are cut and prepared by the cutting machine; the upper die clapboard components are welded with the upper die base plate in a grid structure; the lower die partition plate assemblies are in a grid structure and are welded with the lower die base plate; attaching an upper die base plate of an upper die to the ground, pouring cement into the gap part of the upper die partition plate assembly, welding a plurality of upper die steel plate strips which are adjacently arranged on a plurality of upper die transverse partition plates and a plurality of upper die longitudinal partition plates, and forming an upper die pressing curved surface in a hyperboloid shape on the surface of each upper die steel plate strip; and (3) attaching a lower die base plate of the lower die to the ground, pouring cement into the gap part of the lower die partition plate assembly, welding a plurality of lower die steel plate strips on the plurality of lower die transverse partition plates and the plurality of lower die longitudinal partition plates, and forming a lower die pressing curved surface in a hyperboloid shape on the surface of the lower die steel plate strip. Therefore, the upper die with the upper die pressing curved surface and the lower die with the lower die pressing curved surface are manufactured and formed, the tool is simple to manufacture, the reliability is high, and the pressing curved surface is quickly manufactured according to the required shape. And then, the upper die and the lower die are controlled to move, so that the original material of the double-curvature saddle-shaped plate is quickly pressed, and a finished product of the double-curvature saddle-shaped plate with the curvature meeting the requirement is formed. Meanwhile, the upper die steel plate strip and the lower die steel plate strip are provided with unique functions, because if the cement is only molded in a pressing process, the cement can crack and drop slag due to large pressure, and after the slag is dropped, the partition plate is directly contacted with a pressed steel plate, so that the defects of indentation and the like can be generated, and the quality of a finished product is poor or the finished product cannot be used at all. Therefore, the upper die steel plate strip and the lower die steel plate strip are arranged, so that cement is not directly contacted and pressed in the pressing process, the cement is not dropped, cracked and indented in the pressing process. The double-curvature saddle-shaped plate pressing forming tool has the main advantages of short-time quick tool forming, perfect forming, no indentation, wrinkling, lotus leaf edge and other defects of a processed plate, low labor intensity, processing difficulty reduction, processing time shortening, controllable construction period, energy conservation, environmental protection and low cost.
The present invention has been described in connection with the accompanying drawings, and it is to be understood that the invention is not limited to the specific embodiments disclosed, but is intended to cover various modifications, changes and equivalents of the embodiments of the invention, and its application to other applications without departing from the spirit and scope of the invention.
