Therefore, the utility model is not limited to the basic implementation disclosed below.

[0014] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art in the technical field of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0015] The specific implementation of the utility model is further described in detail below with reference to the accompanying drawings.

[0016] Depend on Figures 1 to 4It is given, including an L-shaped support plate 1, a lower fixed plate 2 is provided on the support plate 1, an upper fixed plate 3 located above the lower fixed plate 2 is provided on the support plate 1, a plurality of guide columns 4 distributed in a rectangular shape are provided between the upper fixed plate 3 and the lower fixed plate 2, a movable plate 5 which can move up and down is provided on the plurality of guide columns 4, a lower mold 6 is provided at the upper end of the lower fixed plate 2, an upper mold 7 which can cooperate with the lower mold 6 is provided at the lower end of the movable plate 5, a movable groove surrounding the lower mold 6 is opened on the lower fixed plate 2, a protective plate 8 is slidably connected in the movable groove, racks 9 are respectively provided on the left and right sides of the lower end of the movable plate 5, a plurality of teeth 10 evenly distributed along the up and down directions are respectively provided on the left and right ends of the protective plate 8, and gears 11 between the rack 9 and the teeth 10 located on the same side are rotatably connected on the left and right sides of the support plate 1, and the gear 11 can mesh with the teeth 10 and the rack 9.

[0017] In order to move the movable plate 5 up and down, the movable plate 5 is slidably connected to the guide column 4 , and a hydraulic press 12 is provided at the upper end of the upper fixed plate 3 , and the output end of the hydraulic press 12 is fixedly connected to the movable plate 5 .

[0018] In order to facilitate the movement of the rack 9, the left and right sides of the lower fixed plate 2 are respectively provided with vertically penetrating through grooves 13, and the rack 9 can pass through the through grooves 13 on the corresponding sides.

[0019] In order to prevent the protection plate 8 from falling, anti-falling blocks 14 are respectively provided on the left and right sides of the upper end of the protection plate 8 .

[0020] In order to increase stability, a counterweight 15 is provided on the support plate 1 .

[0021] In order to facilitate movement, the lower end of the support plate 1 is firstly provided with a plurality of universal wheels distributed in a rectangular shape.

[0022] When the utility model is in use, firstly, the plate blank to be stretched and formed is placed on the lower mold 6, and then the hydraulic press 12 is started. The hydraulic press 12 drives the movable plate 5 to move downward, and the movable plate 5 drives the upper mold 7 to move downward, and at the same time drives the two racks 9 to move downward. The racks 9 move downward for a distance and then insert into the corresponding through grooves 13, and then continue to move downward and pass through the through grooves 13 and mesh with the gears 11 on the corresponding side, driving the gears 11 to rotate. The gears 11 drive the protective plate 8 to move upward through the teeth 10.

At the same time, the protective plate automatically moves upward during the stretching forming to realize the enclosure protection of the working area, preventing the parts from breaking out due to uneven force and causing harm to the operator. At the same time, after the processing is completed, the protective plate automatically moves downward to release the enclosure protection, which is convenient for the operator to take out the parts. This structure is simple, novel in conception, easy to use and highly practical.
