DETAILED DESCRIPTION

[0026] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0027] In one embodiment, see Figure 1 , a metal side panel bending machine for a computer case, comprising a base 1, a clamping mechanism 2 and a bending mechanism 3;

[0028] The clamping mechanism 2 includes a driving support frame 4 fixedly connected to the middle part of the base 1, the driving support frame 4 is arranged in the middle part of the upper surface of the base 1 in a front-to-back direction, the driving support frame 4 is a U-shaped structure with an opening downward, and the upper middle part of the driving support frame 4 is rotatably connected with a vertically arranged driving support shaft 5, and the upper end of the driving support shaft 5 is fixedly connected to the middle part of the lower surface of a horizontally arranged supporting block 6, and a side support frame 7 is arranged in the middle part of the rear side of the base 1. The side support frame 7 is a zigzag structure when viewed from the right side. Through this structure, the upper part of the side support frame 7 can be moved backward, so that when the plate to be bent is placed on the supporting block 6, the backward bending of the side support frame 7 can avoid the plate, so that the plate can be stably rotated with the supporting block 6, and on the side support frame 7 The upper end is fixedly connected to the rear end of the top plate 11 set in the front and rear directions, and a clamping cylinder 9 is set on the front side of the lower surface of the top plate 11, and the piston rod of the clamping cylinder 9 extends downward, and the piston rod of the clamping cylinder 9 is connected to the middle part of the upper surface of the rotating disk 12, and the lower surface of the rotating disk 12 is rotatably connected to the clamping block 8, and guide slide bars 10 are vertically arranged on the front and rear sides of the upper surface of the rotating disk 12, and the top of the guide slide bar 10 is slidably connected to the top plate 11, and the clamping block 8 and the supporting block 6 are rectangular blocks with the same cross-section, and when the clamping block 8 moves downward, the clamping block 8 falls on the upper surface of the supporting block 6, and the surfaces of the clamping block 8 and the supporting block 6 are in contact with each other and are exactly the same, so as to realize the processing of clamping the metal plate, that is, the clamping block 8 and the supporting block 6 can complete the clamping of the large side plate 30;

[0029] The bending mechanism 3 includes columns 20 arranged on both sides of the base 1. The columns 20 are vertically arranged on the left and right sides of the driving support frame 4, and a guide column 21 arranged in a left and right direction is arranged on the side of the upper end of the column 20 away from the supporting block 6. The middle part of the front and rear two guide columns 21 is slidably connected to the front and rear ends of the transverse shift seat 22 arranged in the front and rear directions. When the transverse shift seat 22 moves toward the supporting block 6, the transverse shift seat 22 will fit with the side of the supporting block 6, and because the supporting block 6 will rotate with the driving support shaft 5, the transverse shift seat 22 will fit with the side of the supporting block 6 again, that is, the spacing of the transverse shift seat 22 will change with the size of the supporting block 6 after rotation. The L-shaped bending plate 23 is rotatably connected to the upper surface of the transverse displacement seat 22. When the L-shaped bending plate 23 is rotated to a vertical state, the long side of the L-shaped bending plate 23 will fit on the left and right sides of the clamping block 8, and the short side of the L-shaped bending plate 23 will fit on the top surface of the clamping block 8. Therefore, the cooperation between the L-shaped bending plate 23 and the clamping block 8 can complete the bending process of the metal plate. At this time, the long side of the L-shaped bending plate 23 can complete the bending process of the small side panel 31 with a smaller side size of the chassis, and the short side of the L-shaped bending plate 23 can complete the bending process of the retaining edge 32 of the side panel of the chassis, thereby realizing the subsequent fixing process of the transparent baffle, as shown in the attached figure. Fig. 9 As shown, the chassis assembly 33 includes a large side panel 30, a small side panel 31 and a rib 32. The large side panel 30 will be wrapped around the lower surface of the clamping block 8, the small side panel 31 will be wrapped around the four sides of the clamping block 8, and the rib 32 is located on the upper surface of the clamping block 8, so that when the metal plate is bent, a chassis assembly 33 is formed. At this time, the chassis assembly 33 will be wrapped around the outside of the clamping block 8, and because the metal plate itself can have a certain elasticity, the small side panel 31 can be slightly deflected outward, so that the chassis assembly 33 can be detached from the clamping block 8 to achieve unloading processing.

[0030] In one case of the present embodiment, a rotating drive assembly 19 for driving the driving support shaft 5 to rotate is provided inside the driving support frame 4. The driving assembly 13 can realize the effect of rotating the driving support shaft 5 by 90 degrees, and can also realize the effect of rotating the supporting block 6 in the front-back direction and the left-right direction. The driving assembly 19 includes a driving motor 13 provided on the rear side of the lower surface of the driving support frame 4, the output shaft of the driving motor 13 is fixedly connected to the first bevel gear 14, the first bevel gear 14 is meshedly connected to the second bevel gear 15 fixedly connected to the end of the driving support shaft 5, and the driving motor 13 can realize the rotation of the driving support shaft 5 by gear transmission. The outer sleeve of the driving support shaft 5 is provided with a support disk 17, and the support disk 17 is provided with a support wheel 16 rolling on the upper surface of the driving support frame 4, the lower surface of the supporting block 6 is fixedly connected to the upper end of the support plate 18, and the lower end of the support plate 18 is fixedly connected to the upper surface of the support disk 17. Therefore, the cooperation between the support disk 17 and the support plate 18 can directly transfer the downward force exerted on the supporting block 6 to the driving support frame 4, so that the driving support shaft 5 only needs to provide a rotational force, thereby avoiding the subsequent rotation accuracy of the driving support shaft 5 being affected by the lateral force, and ensuring that the supporting block 6 is in a horizontal state.

[0031] In one case of the present embodiment, a fixing plate 25 is provided at one end of the guide column 21 away from the supporting support block 6, and the fixing plate 25 is fixed to the ends of the front and rear guide columns 21 in a front-to-back direction, that is, two left-to-right guide columns 21 are respectively provided on the left and right sides of the base 1, and the fixing plate 25 serves to improve the structural strength so that the guide columns 21 remain in a horizontal state, and the upper ends of the auxiliary support plates 24 are fixedly connected to the front and rear sides of the lower surface of the fixing plate 25, and the lower ends of the auxiliary support plates 24 are fixedly connected to the front and rear sides of the left and right sides of the base 1, further serving to stabilize the structure, and a transverse cylinder 29 is provided in the middle of the fixing plate 25, the piston rod of the transverse cylinder 29 will extend toward the center of the base 1, and the piston rod of the transverse cylinder 29 is fixedly connected to the side of the transverse seat 22, so that the transverse seat 22 can be pushed to slide left and right along the guide column 21 through the extension and contraction of the piston rod of the transverse cylinder 29.

[0032] In one case of the present embodiment, a protruding plate 26 is provided on the side of the transverse shift seat 22 away from the supporting block 6, and the protruding plate 26 is arranged on the side of the transverse shift seat 22 away from the base 1 in a left-right direction. One end of the protruding plate 26 away from the transverse shift seat 22 is fixedly connected with a rotating shaft 27 arranged in a front-to-back direction. The middle part of the rotating shaft 27 is rotatably connected to the lower end of the bending cylinder 28, and the piston rod of the bending cylinder 28 is extended toward the base 1. The piston rod of the bending cylinder 28 is rotatably connected to the side of the L-shaped bending plate 23. Therefore, the extension and contraction of the piston rod of the bending cylinder 28 can push the L-shaped bending plate 23 to rotate, thereby realizing the bending of the metal plate.

[0033] During the implementation of this embodiment, it is first necessary to cut the complete metal plate into a large rectangular side panel 30, and a small side panel 31 is provided on the side of the large side panel 30, and the end of the small side panel 31 is chamfered to facilitate the subsequent bending of the retaining edge 32. At this time, the ordinary metal plate is cut into a cross-shaped structure, and the middle part of the cross-shaped structure plate is placed on the supporting block 6, and the large side panel 30 is kept completely overlapped with the supporting block 6.

[0034] During the first bending process, the clamping cylinder 9 is started, the clamping pressure block 8 will move downward, and the clamping pressure block 8 and the supporting block 6 will complete the clamping process for the large side panel 30. At this time, the supporting block 6 is in a front-to-back facing state, and the transverse displacement seat 22 is in a state of being in contact with the supporting block 6. The bending cylinder 28 is started, and the bending cylinder 28 pushes the L-shaped bending plate 23 to rotate. At this time, the L-shaped bending plate 23 will push the small side panels 31 on the left and right sides to rotate to a vertical state, and the short side of the L-shaped bending plate 23 will bend the end of the small side panel 31 by ninety degrees again to form a retaining edge 32. The bending cylinder 28 is started in the reverse direction, and the L-shaped bending plate 23 rotates in the reverse direction. The L-shaped bending plate 23 rotates to a horizontal or even downward state, and the L-shaped bending plate 23 is detached from the metal plate.

[0035] In the second bending process, the transverse cylinder 29 is started in the reverse direction, and the transverse seat 22 moves toward the direction of the fixed plate 25. The transverse seat 22 is disengaged from the supporting block 6. At this time, the drive motor 13 is started, and the drive motor 13 drives the supporting block 6 to rotate ninety degrees to present a left-right orientation. Due to the effect of friction, the metal plate to be bent and the clamping block 8 above will also be rotated ninety degrees. At this time, the transverse cylinder 29 is started in the reverse direction again, and the transverse seat 22 will move toward the direction of the supporting block 6. The transverse seat 22 will fit on the surface of the supporting block 6, and the spacing of the transverse seat 22 will change with the size adaptability during the first bending process. Start the clamping cylinder 9 again, and the L-shaped bending plate 23 will bend the other two small side panels 31. At this time, the entire chassis assembly 33 is wrapped around the outside of the clamping block 8, thereby completing the side panel bending process of the chassis.

[0036] The present invention is applicable to a metal side panel bending machine for a computer case. Since the transverse seat 22 will fit the surface of the supporting block 6 when bending the two sides, adaptive adjustment of the distance between the two transverse seats 22 is achieved, that is, the L-shaped bending plate 23 above the transverse seat 22 will realize the bending processing of the four sides of the case. After the metal plate is cut, it only needs to be clamped once on the bending machine to complete the bending, thereby improving the processing efficiency.

[0037] It will be apparent to those skilled in the art that the invention is not limited to the details of the exemplary embodiments described above and that the invention can be implemented in other specific forms without departing from the spirit or essential features of the invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of the invention is defined by the appended claims rather than the foregoing description, and it is intended that all variations falling within the meaning and scope of the equivalent elements of the claims be included in the invention. Any reference numeral in a claim should not be considered as limiting the claim to which it relates.
