This patent uses a hyperbolic panel mold processing device body; the hyperbolic panel mold processing device body is provided with a bracket, a support seat and support legs are provided at the bottom of the bracket, a press is provided at the top of the bracket, and a working platform is provided in the middle of the bracket. The working platform is divided into an upper mold area and a lower mold area. The upper mold area is a hyperbolic panel convex mold, and the lower mold area is a hyperbolic panel concave mold. The curvature sizes of the hyperbolic panel convex mold and the hyperbolic panel concave mold match each other. The press pulls the hyperbolic panel convex mold up and down, and the hyperbolic panel convex mold and the hyperbolic panel concave mold can be closed or opened. After the technical improvement of this utility model, the pier cap panel is spliced ​​with 5 panels, and the single panel is pressed into hyperbolic curvature, which increases the blanking speed, improves material utilization, improves welding efficiency, improves forming degree, and makes the pier column forming smooth.

[0004] In daily use, it has been found that in existing technologies, after stamping, the workpiece tends to fit tightly against the die base. This tight fit between the die and the stamped part increases friction and accelerates die wear. This not only shortens the die life but also increases production costs. Furthermore, if the stamped part fits too tightly against the die base, it may become difficult to release smoothly from the die. This is especially true when the stamped part has complex curves or requires precision, which can easily lead to surface damage such as scratches and indentations. Utility Model Content

[0012] Preferably, the cross section of the sliding rod is circular, and the sliding rod is a stainless steel rod.

[0013] The effects achieved by the above components are: the stainless steel material can increase the service life of the slide bar and prevent the slide bar from excessive rusting during use.

[0014] Preferably, both ends of the arc plate are provided with a lifting structure, and the lifting structure includes a plurality of round rods, and the plurality of round rods are divided into two groups, and the two groups of round rods are fixedly connected to the arc plate, and the arc surface of one group of round rods is fixedly connected to a slide, and the lower surface of the slide is fixedly connected to a lifting plate, and the upper surface of the slide is fixedly connected to a handle.

[0018] Preferably, the arc surface of the handle is fixedly connected with an anti-slip sleeve, and the anti-slip sleeve is a rubber sleeve.

[0019] The effect achieved by the above components is that the anti-slip cover can increase the friction between the hand and the handle to prevent sliding when pulling the handle.

[0020] Compared with the related art, the curved surface processing device for mold production provided by the present invention has the following beneficial effects:

[0021] The utility model provides a curved surface processing device for mold production. By setting a separation structure, in the prior art, after the workpiece is stamped, the workpiece is easily tightly fitted with the die base. If the mold and the stamped part are too tightly fitted, the friction of the mold will increase, causing the mold to wear faster. This not only shortens the service life of the mold, but may also increase production costs. Moreover, if the stamped part is too tightly fitted with the die base, the stamped part may not be able to be smoothly separated from the mold. Especially when the surface of the stamped part has complex curves or precision requirements, it is easy to produce surface scratches, indentations and other damages. This device can easily separate the workpiece from the die base, avoiding the workpiece and the die base being too tightly fitted, which makes it difficult to remove the workpiece after processing.

[0022] By setting up a lifting structure, the processed workpiece can be easily lifted and then taken out, which greatly improves the workpiece processing efficiency. BRIEF DESCRIPTION OF THE DRAWINGS
