After the two rod-shaped palms 201 are pressed on the iron sheet, the plurality of strip-shaped fingers 202 are pressed on the iron sheet, so that the front and rear ends of the iron sheet are fully attached to the two side plates 105. The rod-shaped palm and the plurality of strip-shaped fingers on the mechanical arm are used to make the shell of the set-top box from the iron sheet, and two right angles are pressed out on the iron sheet at one time.

[0033] As shown in Figure 6 , this example can realize the effect of driving the two rod-shaped palms 201 and the plurality of strip-shaped fingers 202 to slide up and down at the same time.

[0034] Since the upper side of the flat plate 101 is fixed with the vertical rods 207 on the left and right sides, the middle parts of the two door-shaped frames 206 are respectively vertically and slidably connected to the two vertical rods 207, the upper ends of the two vertical rods 207 are connected with the top strip 203 through screws, the left and right ends of the top strip 203 are connected with the hydraulic cylinders two 205 through screws, and the movable ends of the two hydraulic cylinders two 205 are respectively connected to the two door-shaped frames 206 through screws.

[0039] As shown in Figures 4-5 , this example can achieve the effect of conveniently punching the iron sheet attached to the side plate 105.

[0040] Since each side plate 105 is provided with a long hole 104, the side plate 105 has a hollow, thereby facilitating punching the iron sheet attached to the side plate 105.

[0041] As shown in Figures 4-5 , this example can achieve the effect of controlling whether the filling strip 108 is inserted into the long hole 104.

[0042] Since the left and right sides of the flat plate 101 are connected with connecting frames 106 through screws, the front and rear sides of each connecting frame 106 are connected with hydraulic cylinders one 107 through screws, and the two filling strips 108 are arranged front and rear, the filling strip 108 is fixed to the movable end of the two hydraulic cylinders one 107 on the same side, the filling strip 108 can be inserted into the long hole 104, the filling strip 108 can be driven to move by the hydraulic cylinder one 107, thereby controlling whether the filling strip 108 is inserted into the long hole 104, when the iron sheet is just bent, the filling strip 108 is inserted into the long hole 104 to support the iron sheet, when the side of the iron sheet needs to be punched, the filling strip 108 is pulled out of the long hole 104, thereby facilitating punching the side of the iron sheet.

[0043] As Figures 4-5 and 7-8 show, this example can achieve the effect of supporting the two side plates 105 and the flat plate 101 through the bottom strip 301 and the four cross rails 303.
