TECHNICAL FIELD

[0001] The present application belongs to the field of case manufacturing, and particularly relates to a case manufacturing device. BACKGROUND

[0002] The main function of a case is to provide a space and a support for the internal devices of a computer, so as to avoid physical damage to the internal devices. Meanwhile, the case can shield electromagnetic radiation, prevent the internal electromagnetic radiation from affecting the health of a user, and prevent external electromagnetic radiation from interfering with the internal boards and electronic components.

[0003] The traditional computer case has a strength structure and a sealing structure due to the need for dust prevention and safety, so that the case cannot be quickly disassembled for maintenance when the internal structure of the case fails, and the disassembly efficiency is low and the operation is troublesome.

[0004] The production of the existing quick-disassembly case needs to go through many production processes, resulting in an increase in the production equipment cost. Designing an improved hinge structure of the case plate of the case can greatly reduce the production cost of the case, but multiple processes are still needed to manufacture the case, resulting in a complicated production process of the case.

[0005] The present application designs a case manufacturing device to improve the hinge mechanism of the traditional quick-disassembly case by sheet metal technology to solve the above problems. SUMMARY

[0007] A case manufacturing device comprises a U-shaped seat and bending mechanisms, wherein four bending mechanisms are sequentially installed in the U-shaped seat along the forming sequence of an upper arc A and an upper arc B of a case plate; the four bending mechanisms jointly participate in the forming of the upper arc A of the case plate, and the last three bending mechanisms participate in the forming of the upper arc B of the case plate; each bending mechanism has two parallel self-rotation roller columns for horizontally clamping different thickness plate materials A or B of the formed case plate, the two roller columns are driven by two motors A at both ends to freely move in a direction perpendicular to the roller columns, and the two roller columns are driven by two motors C at both ends to perform synchronous revolution with equal radii.

[0008] As a further improvement of the present technology, the bending mechanism comprises sliding seat A, motor A, sliding seat B, motor B, guide seat B, sliding block, motor D, roller shaft, roller column, wherein two sliding seat A are symmetrically distributed and driven by corresponding motor A to synchronously slide on the two inner side walls of the U-shaped seat; two sliding seat B are symmetrically distributed and driven by corresponding motor B to synchronously slide in the two sliding seat A; a horizontal rod is installed on each sliding seat B, and a fixed seat is installed at the end of each horizontal rod; a rotating pin driven by motor C and parallel to the roller column is rotated in the circular groove of each fixed seat; two sliding blocks driven by motor D synchronously slide in the guide seat B in the direction perpendicular to the rotating pin; and the roller shaft with the hollow roller column is connected one by one through nesting rotation between the sliding blocks in the two guide seats B.

[0009] As a further improvement of the present technology, the center axis of the rotating pin coincides with the center axis of the two roller columns, which ensures that the two roller columns in each bending mechanism can effectively bend the plate A or plate B.

[0010] As a further improvement of the present technology, a U-shaped guide seat A is installed on the sliding seat A, and the two branches of the guide seat A horizontally slide in the two sliding grooves A on the corresponding side walls of the U-shaped seat; the internal thread sleeve on the guide seat A is screwed with the screw rod A installed on the side wall of the U-shaped seat and in transmission connection with the output shaft of the corresponding side motor A; the threaded hole in the sliding seat B is screwed with the screw rod B in rotational cooperation with the corresponding sliding seat A and in transmission connection with the output shaft of the corresponding motor B.

[0011] As a further improvement of the present technology, a gear ring is installed on the rotating pin, and the gear ring is in meshing engagement with the gear A on the output shaft of the corresponding side motor C.

[0012] As a further improvement of the present technology, a gear D is in rotational cooperation with the rotating pin, and the gear D is in meshing engagement with the gear C installed on the corresponding guide seat B and the gear E on the output shaft of the corresponding side motor D; the gear B installed on the shaft of the gear C is in meshing engagement with the gear rack on the two sliding blocks in the corresponding guide seat B.

[0013] Compared with the traditional computer case production equipment, the present application can produce the five case plates in hinged relationship in the quick-release case through the sheet metal process of the plate A or plate B by the four bending mechanisms, and the production process is simple and not complicated, the production efficiency is high, and the production cost is low.

[0014] In addition, due to the unique hinged mounting relationship of the case produced by the present application, the case can be quickly disassembled when internal failure occurs and needs to be repaired, thereby improving the disassembly efficiency of the case and the internal repair efficiency of the case.

[0015] The present application has the advantages of simple structure and good use effect. BRIEF DESCRIPTION OF DRAWINGS

[0026] The accompanying drawings are schematic diagrams illustrating embodiments of the present invention to facilitate understanding of the structural operating principle. Specific product structures and dimensions can be determined based on the usage environment and conventional technologies.

[0027] like Figure 1 As shown, it includes a U-shaped base 1 and a bending mechanism 3, wherein, as Figure 1 , 2 As shown, four bending mechanisms 3 are sequentially installed inside the U-shaped base 1 along the forming sequence of the arc A29 and arc B30 on the chassis plate 28; as Figure 7 , 8As shown in Figure 9, four bending mechanisms 3 jointly participate in the forming of the upper arc portion A29 of the chassis plate 28, and the latter three bending mechanisms 3 participate in the forming of the upper arc portion B30 of the chassis plate 28; as Figure 5 , 7 As shown, each bending mechanism 3 has two parallel rotating rollers 27 that horizontally clamp the forming machine box plate 28 with different thickness plates A33 or B36. The two rollers 27 can move freely in a direction perpendicular to the rollers 27 under the drive of two motors A8 at both ends, and can also revolve synchronously with the same radius under the drive of two motors C17 at both ends.

[0028] like Figure 5 As shown, the bending mechanism 3 includes a slide A4, a motor A8, a slide B9, a motor B11, a guide B18, a slider 19, a motor D25, a roller 26, and a roller column 27, wherein... Figure 2 , 4 As shown in Figure 5, two slide blocks A4, symmetrically distributed on the left and right and driven by corresponding motors A8, slide synchronously on the two inner sidewalls of the U-shaped base 1; Figure 2 , 3 As shown, two slide blocks B9, symmetrically distributed on the left and right and driven by corresponding motors B11, slide synchronously within two slide blocks A4; as Figure 2 , 5 As shown, each slide B9 is equipped with a horizontal bar 12, and a fixed seat 13 is installed at the end of each horizontal bar 12; as Figure 5 , 6 As shown, each fixed seat 13 has a rotating pin 14 driven by a motor C17 and parallel to the roller 27 in its circular groove. Two sliders 19 driven by a motor D25 slide synchronously in the guide seat B18 installed at one end of the rotating pin 14 in a direction perpendicular to the rotating pin 14, facing each other or backing each other. The sliders 19 in the two guide seats B18 are connected one-to-one by a roller shaft 26 with a hollow roller 27 nested and rotating.

[0029] like Figure 5 , 6 As shown, the central axis of the pivot pin 14 coincides with the central axis of revolution of the two rollers 27, ensuring that the two rollers 27 in each bending mechanism 3 can effectively bend the plate A33 or the plate B36.

[0030] like Figure 3 , 4 As shown, a U-shaped guide seat A5 is installed on the slide A4, and the two branches of the guide seat A5 slide horizontally in the two grooves A2 on the corresponding side wall of the U-shaped seat 1; as Figure 2 , 3 As shown, the internal threaded sleeve 6 on guide seat A5 engages with the screw A7 mounted on the side wall of U seat 1 and connected to the output shaft of the corresponding motor A8; as Figure 3 ,5 As shown in the figure, the threaded hole on the slide B9 is screwed with a screw rod B10 which is in rotational cooperation with the corresponding slide A4 and is in transmission connection with the output shaft of the corresponding motor B11.

[0031] As shown in the figure, Figure 5 , 6 The pin 14 is provided with a gear ring 15 which is in mesh with the gear A16 on the output shaft of the corresponding side motor C17.

[0032] As shown in the figure, Figure 5 , 6 The pin 14 is provided with a gear D23 which is in mesh with the gear C22 installed on the corresponding guide base B18 and the gear E24 on the output shaft of the corresponding side motor D25; the gear B21 installed on the shaft of the gear C22 is in mesh with the rack 20 on the two sliders 19 in the corresponding guide base B18.

[0033] The working process of the present application: in the initial state, the four pairs of roller columns 27 in the four bending mechanisms 3 are distributed horizontally in turn, one pair of roller columns 27 in each bending mechanism 3 is distributed vertically, the center axes of the four upper roller columns 27 in the four bending mechanisms 3 are located in the same horizontal plane, and the center axes of the four lower roller columns 27 are located in the same horizontal plane.

[0034] When the production of the case plate 28 is needed, as shown in the figure, Figure 8 First, the four edges of the plate A33 are punched out by the punching process to form the bending parts A34, and three interval bending parts B35 are punched out on each bending part A34; one edge of the plate B36 is punched out by the punching process to form the bending part A34, and three interval bending parts C37 are punched out on the bending part A34.

[0035] Then, the plate A33 or the plate B36 is inserted horizontally into one pair of roller columns 27 in each bending mechanism 3 in turn, and the bending part B35 on the plate A33 or the bending part C37 on the plate B36 is located at the front end of its movement.

[0036] After the plate A33 or the plate B36 is inserted into one pair of roller columns 27 in the bending mechanism 3, the control system starts to start two motors D25 in each bending mechanism 3, and the two motors D25 in each bending mechanism 3 drive the corresponding two sliders 19 to move vertically towards each other through the corresponding gears E24, gears D23, gears C22, gears B21 and two racks 20, and the left and right pairs of sliders 19 in the bending mechanism 3 drive the two roller columns 27 to move towards each other through the corresponding roller shafts 26 and finally clamp the plate A33 or the plate B36.

[0037] Keep the two rollers 27 in the first bending mechanism 3 clamped on the plate A 33 or the plate B 36, and start the motor A 8, the motor B 11 and the motor C 17 in any one of the remaining three bending mechanisms 3, so that the two motors A 8 in each bending mechanism 3 drive the corresponding slide A 4 horizontally to the direction of the first bending mechanism 3 through the corresponding screw rod A 7, the internal thread sleeve 6 and the guide base A 5, and the two motors B 11 in each bending mechanism 3 drive the corresponding slide B 9 vertically upward in the corresponding slide A 4 through the corresponding screw rod B 10, so that the pair of rollers 27 in the bending mechanism 3 can move in two degrees of freedom in the vertical plane. At the same time, the two motors C 17 in each bending mechanism 3 drive the rotating pin 14 on the corresponding fixed seat 13 to rotate through the corresponding gear A 16 and the gear ring 15, and the rotating pin 14 drives the two rollers 27 installed between the two pairs of sliding blocks 19 to revolve with the same radius. The movement range of the slide A 4 in the third bending mechanism 3 is greater than that of the slide A 4 in the second bending mechanism 3, the movement range of the slide B 9 in the third bending mechanism 3 is greater than that of the slide B 9 in the second bending mechanism 3, and the revolving angle of the rollers 27 in the three bending mechanisms 3 is the same.

[0038] The above movement of the remaining three bending mechanisms 3 and the static state of the first bending mechanism 3 make the bending part A 34 of the plate A 33 or the plate B 36 bend upward by 90 degrees. Then, the motor A 8, the motor B 11 and the motor C 17 in the three bending mechanisms 3 that have moved are started again, so that the three pairs of rollers 27 in the three bending mechanisms 3 perform circular arc bending on the bending part A 34. In this process, the rollers 27 in the remaining three bending mechanisms 3 will revolve around the corresponding roller shaft 26 to reduce the friction between the rollers 27 and the plate A 33 or the plate B 36.

[0039] After the first circular arc on the bending part A 34 is completed, the two rollers 27 in the second bending mechanism 3 are kept static, and the motor A 8, the motor B 11 and the motor C 17 in the last two bending mechanisms 3 are started, so that the two rollers 27 in the last two bending mechanisms 3 bend the bending part A 34 around the roller 27 below the plate A 33 or the plate B 36 in the second bending mechanism 3, and make the downward bending part form a second circular arc with the same center axis as the first circular arc under the movement of the two pairs of rollers 27 in the last two bending mechanisms 3.

[0040] When the two rollers 27 in the third bending mechanism 3 are located in the same horizontal plane as the two rollers 27 in the first bending mechanism 3 one by one, the two rollers 27 in the third bending mechanism 3 are kept stationary, and the motor A8, the motor B11 and the motor C17 in the fourth bending mechanism 3 are continuously started, so that the two rollers 27 in the fourth bending mechanism 3 drive the remaining part of the bending part A34 on the plate A33 or the plate B36 to continue to bend horizontally around the upper roller 27 in the third bending mechanism 3.

[0041] After the remaining part of the bending part A34 of the plate A33 or the plate B36 is completed, the two arcs of the bending part A34 are formed as the arc part A29 on the plate A33 or the plate B36, then the motor A8 in the third and fourth bending mechanisms 3 is started first, so that the two rollers 27 in the third and fourth bending mechanisms 3 move horizontally to the bending part B35 of the plate A33 or the bending part C37 of the plate B36 for a distance, so that the two rollers 27 in the third bending mechanism 3 are separated from the bending part of the second arc and the horizontal part of the bending part A34 to provide a position for the two rollers 27 in the second bending mechanism 3.

[0042] Then, the motor A8, the motor B11 and the motor C17 in the second bending mechanism 3 are started, so that the two rollers 27 in the second bending mechanism 3 finally reach the bending part of the second arc and the horizontal part of the bending part A34, so that the two rollers 27 in the second bending mechanism 3 provide a force point for the bending of the bending part B35 of the plate A33 or the bending part C37 of the plate B36.

[0043] Then, the motor A8 in the third bending mechanism 3 and the fourth bending mechanism 3 is started, so that the rollers 27 in the two bending mechanisms 3 continue to move to the bending part B35 on the plate A33 or the bending part C37 on the plate B36. When the two rollers 27 in the third bending mechanism 3 reach the root of the bending part B35 on the plate A33 or the bending part C37 on the plate B36, the two rollers 27 in the third bending mechanism 3 are kept stationary and the motor A8, the motor B11 and the motor C17 in the fourth bending mechanism 3 are continuously started, so that the fourth bending mechanism 3 bends the bending part B35 on the plate A33 or the bending part C37 on the plate B36 around the roller 27 in the third bending mechanism 3 above the plate A33 or the plate B36 to form the arc part B30.

[0044] After the fourth bending mechanism 3 completes the bending of the arc part B30 of the bending part B35 on the plate A33 or the bending part C37 on the plate B36, the motor A8 in the first bending mechanism 3 is started first, so that the two rollers 27 in the first bending mechanism 3 horizontally move away from the end of the formed arc part A29 to provide a position for the rollers 27 in the last three bending mechanisms 3.

[0045] Then, the motor A8, the motor B11 and the motor C17 of the last three bending mechanisms 3 are started, so that the three pairs of roller columns 27 in the last three bending mechanisms 3 return along the plate A33 or the plate B36 in the original path and finally pass the arc part B30 to reach the horizontal part of the plate A33 or the plate B36, then the motor D25 in the four bending mechanisms 3 is started, so that the pair of roller columns 27 in each bending mechanism 3 moves vertically and oppositely to release the clamping of the plate A33 or the plate B36, and finally the plate A33 or the plate B36 after sheet metal forming is horizontally pulled out between the four roller columns 27 of the four bending mechanisms 3 to complete the forming of the case plate 28.

[0046] In summary, the beneficial effects of the present application are: the four bending mechanisms 3 of the present application can complete the production of the case plate 28 of the five surfaces in the hinged relationship in the quick-release case through the sheet metal process of the plate A33 or the plate B36, the production process is simple and not complicated, the production efficiency is high and the production cost is low.

[0047] In addition, due to the unique hinged mounting relationship of the case produced by the present application, when the case needs to be repaired due to internal failure, it can be quickly disassembled, improving the disassembly efficiency of the case and the internal repair efficiency of the case.

Claims

1. A chassis manufacturing equipment, characterized in that: It includes a U-shaped base and bending mechanisms. Four bending mechanisms are installed sequentially inside the U-shaped base along the forming order of arc A and arc B on the chassis plate. The four bending mechanisms work together to form arc A on the chassis plate, and the latter three bending mechanisms work to form arc B on the chassis plate. Each bending mechanism has two parallel rotating rollers that horizontally clamp the forming chassis plate of different thicknesses, A or B. The two rollers can move freely in a direction perpendicular to the rollers under the drive of two motors A at their two ends, and can also revolve synchronously with the same radius under the drive of two motors C at their two ends. The bending mechanism includes a slide A, a motor A, a slide B, a motor B, a guide B, a slider, a motor D, a roller shaft, and a roller column. The roller column is hollow. Two slides A, symmetrically distributed and driven by their respective motors A, slide synchronously on the two inner sidewalls of the U-shaped base. Two slides B, symmetrically distributed and driven by their respective motors B, slide synchronously within two slides A. Each slide B is equipped with a horizontal rod, and a fixed seat is installed at the end of each horizontal rod. A pivot pin, driven by a motor C and parallel to the roller column, rotates in the circular groove of each fixed seat. Two sliders driven by motor D slide synchronously in opposite directions or in the direction perpendicular to the pivot pin, within the guide B installed at one end of the pivot pin. The sliders within the two guide seats B are connected one-to-one by a roller shaft with a nested, rotating hollow roller column. During use, keep the two rollers in the first bending mechanism clamping plate A or plate B stationary. Start motors A, B, and C in the remaining three bending mechanisms. This causes the two motors A in each bending mechanism to drive the corresponding slide A to slide horizontally towards the direction of the first bending mechanism. The two motors B in each bending mechanism drive the corresponding slide B to slide vertically upward within the corresponding slide A. The two motors C in each bending mechanism drive the pivot pin on the corresponding fixed seat to rotate. The pivot pin drives the two rollers to revolve at the same radius, causing the bent part A of plate A or plate B to bend upward by 90 degrees. Then, start motors A, B, and C in the three bending mechanisms that have already moved again, causing the three pairs of rollers in the three bending mechanisms to perform an arc bend on the bent part A. After the first arc on the bent part A is completed, keep the two rollers in the second bending mechanism stationary, and continue to start motors A, B and C in the latter two bending mechanisms. This causes the two rollers in the latter two bending mechanisms to bend the bent part A around the roller in the second bending mechanism located below the plate A or plate B, and the downward bending part forms a second arc with the same central axis as the first arc under the movement of the two pairs of rollers in the latter two bending mechanisms. When the two rollers in the third bending mechanism are aligned with the two rollers in the first bending mechanism on the same horizontal plane, keep the two rollers in the third bending mechanism stationary and start motors A, B and C in the fourth bending mechanism. The two rollers in the fourth bending mechanism will drive the remaining part of the bending section A on board A or board B to continue bending horizontally around the upper roller in the third bending mechanism. After the remaining part of the bent section A of board A or board B is bent horizontally, the two arcs of the bent section A form the arc section A on board A or board B.
