The rectangular slotted frame 3 is used to support the unfolded metal protective shell. The spline support shaft 4 is rotatably connected to the slotted slide frame 2, and the adjustment component 5 is fixedly installed on the slotted slide frame 2. The bending component 6 is also fixedly installed on the slotted slide frame 2.

[0044] The adjusting assembly 5 includes a slotted support seat 51, a screw rod 1 52, a perforated sliding block 53, a screw rod 2 54, a slotted sliding block 55, a telescopic block 56 and a first return spring 57. The slotted support seat 51 is fixedly installed on the slotted slide rail frame 2. The slotted support seat 51 is rotatably connected with the screw rod 1 52. The screw rod 1 52 is connected with the perforated sliding block 53 by threaded fitting. The perforated sliding block 53 is slidably connected to the slotted support seat 51. The perforated sliding block 53 close to the screw rod 1 52 is symmetrically rotatably connected with the screw rod 2 54. The perforated sliding block 53 is used to support the unfolded metal protective shell. The screw rod 2 54 is connected with the slotted sliding block 55 by threaded fitting. The slotted sliding block 55 is slidably connected with the telescopic block 56. The telescopic block 56 contacts the perforated sliding block 53 with each other. The slotted sliding block 55 is connected with a first return spring 57. The first return spring 57 far away from the slotted sliding block 55 is fixedly connected to the telescopic block 56.

[0045] The bending assembly 6 includes a cylinder 61, a lower pressure frame 62, a lower pressure rod 63, a second return spring 64, a wedge block 1 65, a third return spring 66, a wedge block 2 67 and a fourth return spring 68. The cylinder 61 is fixedly installed on the slotted slide rail frame 2, and a lower pressure frame 62 is welded at one end of the telescopic shaft of the cylinder 61. The lower pressure frame 62 is used to perform secondary bending on the metal protective shell. The lower pressure frame 62 is slidably connected to the lower pressure rod 63, and the lower pressure rod 63 is used to bend the metal protective shell. A second return spring 64 is fixedly connected to the rod 63, and one end of the second return spring 64 away from the lower pressure rod 63 is fixedly connected to the lower pressure frame 62.

[0046] When a metal protective shell needs to be made, the staff manually places the unfolded metal protective shell on the spline support shaft 4. The rectangular slotted frame 3 and the hole-opening sliding block 53 support the unfolded metal protective shell. The staff manually rotates the screw rod 1 52 to adjust the position of the hole-opening sliding block 53 and the device thereon according to the bending width as needed. The staff manually rotates the screw rod 2 54. Since the hole-opening sliding block 53 blocks the telescopic block 56, the two slotted sliding blocks 55 move toward or relative to each other. The distance between the two slotted sliding blocks 55 is adjusted according to the width of the metal protective shell, so that this equipment can produce metal protective shells of different specifications.

[0047] The staff manually holds the metal protective shell, and then manually controls the telescopic shaft of the cylinder 61 to extend. The extension of the cylinder 61 drives the lower pressure frame 62 and its upper device to move downward, so that the lower pressure rod 63 and the metal protective shell contact each other. The lower pressure rod 63 bends the metal protective shell, and the lower pressure frame 62 and its upper device continue to move downward. The second return spring 64 is compressed, and the lower pressure frame 62 performs a second bend on the metal protective shell. Then the staff manually controls the telescopic shaft of the cylinder 61 to contract. The contraction of the cylinder 61 drives the lower pressure frame 62 and its upper device to move upward. The staff manually rotates the metal protective shell, and repeats the above operation three times to bend the four sides of the metal protective shell.

[0048] Example 2

[0049] On the basis of Example 1, Figure 8-11 As shown, it also includes a fixing component 7, the slotted slide frame 2 is slidably connected with the fixing component 7, the fixing component 7 is used to fix the metal protective shell, the fixing component 7 includes a double-sided wedge frame 71, a fifth return spring 72, a four-corner sliding frame 73, a magnetic disk 74, a sixth return spring 75, a limit frame 76 and a seventh return spring 77, the slotted slide frame 2 is slidably connected with the double-sided wedge frame 71, a pair of fifth return springs 72 are fixedly connected to the double-sided wedge frame 71, one end of the fifth return spring 72 away from the double-sided wedge frame 71 is fixedly connected to the slotted slide frame 2, and the spline support shaft 4 slides on the spline support shaft 4. The slotted rail frame 2 is connected with a four-corner sliding frame 73, which is in contact with the double-sided wedge frame 71. The four-corner sliding frame 73 is sleeved with magnetic disks 74 in a four-corner distribution manner. The magnetic disks 74 are used to absorb the metal protective shell. The four-corner sliding frame 73 is fixedly connected with a sixth return spring 75, one end of the sixth return spring 75 is fixedly connected to the spline support shaft 4. The slotted rail frame 2 is slidably connected with a limit frame 76, and the limit frame 76 is used to clamp the double-sided wedge frame 71. The limit frame 76 is connected with a seventh return spring 77, and one end of the seventh return spring 77 away from the limit frame 76 is fixedly connected to the slotted rail frame 2.

[0050] When the lower pressing frame 62 moves downward, the lower pressing frame 62 will push the double-sided wedge frame 71 to move away from the rectangular slotted frame 3, and the double-sided wedge frame 71 will push the four-corner sliding frame 73 and the upper device to move upward, and the magnetic disk 74 can absorb the metal protective shell, eliminating the trouble of manually holding the metal protective shell. At the same time, the double-sided wedge frame 71 will push the limit frame 76 to move downward, and then the stretched seventh reset spring 77 will reset and drive the limit frame 76 to move upward to jam the double-sided wedge frame 71, preventing the fifth reset spring 72 from resetting, so that the double-sided wedge frame 71 can hold the four-corner sliding frame 73.

[0051] Example 3

[0052] On the basis of Example 2, Fig.10 As shown, it also includes a rotating component 8, which is slidably connected to the rectangular slotted frame 3.

An overrunning clutch 85 is arranged on the spline support shaft 4, and a rotating gear 84 is fixedly connected to the overrunning clutch 85, and the rotating gear 84 and the wedge-shaped rack frame 82 are meshed with each other.

[0053] The lower pressing frame 62 will drive the special-shaped pressing rod 81 to move downward, and the special-shaped pressing rod 81 will push the wedge-shaped rack frame 82 to move toward the double-sided wedge-shaped frame 71. The wedge-shaped rack frame 82 pushes the rotating gear 84 and the overrunning clutch 85 to rotate. At this time, the overrunning clutch 85 will not transmit power to the spline support shaft 4. When the lower pressing frame 62 drives the special-shaped pressing rod 81 to move upward, the special-shaped pressing rod 81 is separated from the wedge-shaped rack frame 82, so that the compressed eighth reset spring 83 resets and drives the wedge-shaped rack frame 82 to move away from the double-sided wedge-shaped frame 71, and then the wedge-shaped rack frame 82 pushes the rotating gear 84 and the upper device to rotate. According to the number of teeth of the wedge-shaped rack frame 82 and the rotating gear 84, it can be known that the wedge-shaped rack frame 82 pushes the rotating gear 84 and the upper device to rotate ninety degrees, so that the disk 74 drives the metal protective shell to rotate ninety degrees, which is convenient for bending the other side of the metal protective shell. Repeat the above operation to bend the four sides of the metal protective shell. When the metal protective shell is completed, the staff manually pulls the limit frame 76 to move downward, and the limit frame 76 no longer clamps the double-sided wedge frame 71. The compressed fifth reset spring 72 resets and drives the double-sided wedge frame 71 to move toward the direction close to the rectangular slot frame 3. The double-sided wedge frame 71 is separated from the four-corner sliding frame 73. The compressed sixth reset spring 75 resets and drives the four-corner sliding frame 73 and the device thereon to move downward, and the magnetic disk 74 no longer adsorbs the metal protective shell.
