[0036] In order to facilitate understanding of the above technical solution of the present invention, the working principle or operation method of the present invention in the actual process is described in detail below.
[0037] In actual application, the guide block 9 drives the placement plate 1007 to move out of the box 1001 from the feed port 1005 under the action of the motor 7 driving the threaded screw 8, and then the plate is placed on the placement plate 1007, and the placement plate 1007 is retracted into the box 1001. At the same time, due to the action of the elastic connecting rope, the opening and closing door will automatically fall to close the feed port 1005. At this time, the plate is inside the box 1001, and the electric heating tube 1004 irradiates and preheats the plate. The electric heating tube 1004 drives the rectangular plate 1003 to move up and down as the first cylinder 1002 moves, and the irradiation distance between the plate and the plate can be adjusted, and the heat is transferred from top to bottom. , so that the plate is preheated evenly. Since the insulation plate 1009 is set inside the box 1001, the heat leakage and loss during the preheating process can be reduced. The preheated plate continues to be discharged from the discharge port 1006 as the placement plate 1007 moves. People take the plate down and place it on the hot pressing mold 2. The second cylinder 1102 drives the fixed pressing plate 1103 to move downward, pressing the corners of the plate to fix it. The anti-slip strip 1104 increases the contact friction between the fixed pressing plate 1103 and the plate workpiece, thereby further improving the use effect of the fixing component 11. Finally, the hot pressing plate 5 is driven by the hydraulic cylinder 4 to hot press the plate into shape.
[0038] In summary, with the aid of the above-mentioned technical scheme of the utility model, the preheating component 10 is set up to preliminarily preheat the plate that needs hot pressing processing. The electric heating tube 1004 can adjust the irradiation distance between the plate and the electric heating tube 1004 as the first cylinder 1002 drives the rectangular plate 1003 to move up and down, and the heat is transferred from top to bottom to preheat the plate evenly. During the preheating process, the entire preheating component 10 has a good thermal insulation effect and reduces heat loss. After preheating, the plate can be automatically output to the outside of the box 1001, and it is easy to use. The setting of the fixing component 11 can press and fix the edge of the plate during the hot pressing forming process to avoid the plate workpiece being displaced by force during the hot pressing process and affecting the finished product effect. With the special shape of the support bottom plate 12, the contact area between the entire processing equipment and the ground is increased, which improves the placement stability of the equipment. With the flexible rubber pad, the shaking during the hot pressing process can be further reduced, making the hot pressing process more stable.
