The pull belts on both sides tighten the surface of the material to be processed and stick it to the arc surface of the positioning mold. At this time, the two sliding platforms are close to the movable worktable in the middle of the frame. , and the movable workbench and the sliding platform are flush, and then the horizontal driving devices at both ends of the frame drive the sliding platform to move outward, that is, away from the movable workbench. The cylinder device stretches and extrudes the material left and right, and the movable table moves upwards to realize the extrusion of the curved surface of the material. At this time, the material is stretched and adjusted in the longitudinal and transverse directions to make the material form the curved surface of the mold. The kinematic mechanism can realize convenient, precise and efficient processing of different curved surface radians. When it is necessary to switch workpieces with different materials and surfaces, just adjust the corresponding mold type and fix it.

The beneficial effect of the utility model is that: the utility model is used for processing curved surface materials, the material is pulled tightly on the surface of the positioning mold through the pull belt hydraulic cylinder device, and the horizontal drive device is used to drive the sliding platform to move to both sides of the frame, and the lifting drive device drives The movable table moves upwards, so that the material forms a certain stretching and extrusion pressure in three directions, so that various complex curved surface molding can be satisfied. Solve the problems of low efficiency, high cost and high difficulty hyperboloid stamping processing. There is no noise in the processing process, and the requirements for mold materials are not high, reducing the number of finished molds.
