Description

Technical Field

[0001] This utility model relates to the field of filing cabinet manufacturing technology, and in particular to a bending mechanism for filing cabinet manufacturing. Background Technology

[0002] The metal filing cabinet panel is made from a rectangular metal plate. During the manufacturing process, a bending machine is used to bend the metal plate. After bending, the metal plate can be assembled into a filing cabinet by welding, riveting, or bolting.

[0003] A search revealed that utility model patent CN220005504U discloses a bending mechanism for filing cabinet production. By setting a positioning component, the metal plate can be stably positioned during bending, preventing the metal plate from sliding or shifting during bending, which would lead to incorrect dimensions after bending. At the same time, it also reduces resource waste and avoids the production of defective products during bending, greatly increasing the practicality of the bending mechanism for filing cabinet production.

[0004] Although the above-mentioned device can achieve the positioning operation when bending the metal sheet of the cabinet, during the actual bending process, the two ends of the sheet will move due to deformation. When the two ends of the sheet move, they will scrape against the inner wall of the positioning plate, which will not only cause obvious noise, but also affect the quality of the sheet.

[0005] Therefore, it is necessary to invent a bending mechanism for the production of filing cabinets to solve the above problems. Utility Model Content

[0006] The purpose of this utility model is to provide a bending mechanism for filing cabinet production. The L-shaped positioning push plate can move synchronously with the end of the metal sheet during the bending process, thereby reducing friction. At the same time, the rubber pad can further reduce friction noise and friction damage compared to hard objects, so as to ensure the quality of the sheet. This solves the problem mentioned in the background art that during the actual bending process of metal sheets, the two ends of the sheet will move due to deformation, and the two ends of the sheet will scrape against the inner wall of the positioning plate when they move, which will not only cause obvious noise, but also affect the quality of the sheet.

[0007] According to one aspect of this disclosure, a bending mechanism for manufacturing filing cabinets is provided, comprising:

[0008] A metal sheet support mechanism is used to support the metal sheet to be bent.

[0009] Bending assembly, the bending assembly being used in conjunction with a metal sheet support mechanism to bend the metal sheet; and

[0010] Four sets of rectangularly distributed movable positioning mechanisms, each set including an electric push rod fixedly mounted on the side of the gantry frame. The output shaft of the electric push rod extends to the inside of the gantry frame. A movable plate is fixedly mounted at the end of the output shaft of the electric push rod. A longitudinal groove is formed on the inner side of the movable plate. Two parallel guide optical shafts are fixedly mounted on the inner side of the longitudinal groove. A longitudinal slider is slidably sleeved on the outer side of the two guide optical shafts. A connecting block is rotatably connected to the side of the longitudinal slider away from the electric push rod via a pin. An L-shaped positioning push plate is fixedly mounted at the bottom of the connecting block. A rubber pad is adhered to the inner side of the L-shaped positioning push plate.

[0011] The bending mechanism for producing a filing cabinet according to at least one embodiment of the present disclosure includes a base, wherein a bearing seat is fixedly disposed at the top center of the base.

[0012] According to at least one embodiment of the filing cabinet manufacturing bending mechanism of the present disclosure, a bending groove is provided at the center of the top of the support base, and clearance grooves are provided at the four corners of the top of the support base.

[0013] The bending mechanism for producing a filing cabinet according to at least one embodiment of the present disclosure includes a gantry frame fixedly disposed on the top of a base, and a hydraulic cylinder fixedly disposed on the top of the gantry frame.

[0014] According to at least one embodiment of the filing cabinet production bending mechanism of the present disclosure, the output shaft of the hydraulic cylinder passes through the gantry and extends to the inside of the gantry, and a bending pressure block is fixedly connected to the end of the output shaft of the hydraulic cylinder, the bending pressure block being located directly above the bending groove.

[0015] The technical effects and advantages of this utility model are as follows:

[0016] This invention features a movable positioning mechanism. After a metal sheet is placed on top of the support, four electric push rods move a movable plate inward. As the movable plate moves inward, it drives an L-shaped positioning push plate inward via a guide shaft, a longitudinal slider, and a connecting block. The L-shaped positioning push plate pushes the metal sheet with rubber pads until the four rubber pads are in contact with both ends of the metal sheet, thus completing the positioning. During subsequent bending, when the front and rear ends of the metal sheet warp, the metal sheet pushes the L-shaped positioning push plate with the rubber pads. The L-shaped positioning push plate rotates around the pin on the connecting block, maintaining continuous contact with the metal sheet. Simultaneously, the L-shaped positioning push plate drives the longitudinal slider to move upward along the guide shaft inside the longitudinal groove, thus moving synchronously with the end of the metal sheet to reduce friction. Compared to existing technologies, the L-shaped positioning push plate in this invention moves synchronously with the end of the metal sheet during bending, reducing friction. Furthermore, the rubber pads, compared to hard materials, further reduce friction noise and damage, ensuring the quality of the sheet. Attached Figure Description

[0025] For descriptive purposes, this disclosure may use spatial relative terms such as “below,” “under,” “below,” “down,” “above,” “above,” “higher,” and “side (e.g., in a “sidewall”)” to describe the relationship between one component and another component as shown in the accompanying drawings. In addition to the orientations depicted in the drawings, the spatial relative terms are also intended to encompass different orientations of the device during use, operation, and / or manufacture. For example, if the device in the drawings is flipped, a component described as “below” or “under” other components or features would subsequently be positioned “above” said other components or features. Thus, the exemplary term “below” can encompass both “above” and “below” orientations. Furthermore, the device may be otherwise positioned (e.g., rotated 90 degrees or in other orientations), thus interpreting the spatial relative descriptive terms used herein accordingly.

[0026] Figure 1 This is a schematic diagram of the overall structure of the bending mechanism for producing a filing cabinet according to one embodiment of the present disclosure.

[0027] Figure 2 This is a schematic diagram of the metal sheet support mechanism 1 and bending assembly 2 of the bending mechanism for producing a filing cabinet according to one embodiment of the present disclosure.

[0028] Figure 3 This is a schematic diagram of the movable positioning mechanism 3 of the bending mechanism for producing a filing cabinet according to one embodiment of the present disclosure.

[0029] like Figures 1-3 As shown, the bending mechanism for producing the filing cabinet disclosed herein may include components such as a metal sheet support mechanism 1, a bending assembly 2, and a movable positioning mechanism 3.

[0030] like Figure 2 As shown in the present disclosure, the metal sheet support mechanism 1 includes a base 11, a bearing seat 12 is fixedly provided at the top center of the base 11, a bending groove 13 is provided at the top center of the bearing seat 12, and clearance grooves 14 are provided at the four corners of the top of the bearing seat 12.

[0031] Therefore, the metal sheet can be supported by the bearing seat 12, the bending groove 13 can limit the sheet during the bending process, and the clearance groove 14 can avoid the movable positioning mechanism 3, so that the movable positioning mechanism 3 can be positioned by the side of the sheet.

[0032] like Figure 2As shown, in a preferred embodiment, the bending assembly 2 includes a gantry frame 21 fixedly mounted on the top of the base 11. A hydraulic cylinder 22 is fixedly mounted on the top of the gantry frame 21. The output shaft of the hydraulic cylinder 22 passes through the gantry frame 21 and extends to the inside of the gantry frame 21. A bending block 23 is fixedly connected to the end of the output shaft of the hydraulic cylinder 22. The bending block 23 is located directly above the bending groove 13.

[0033] Therefore, after the metal sheet is positioned, the hydraulic cylinder 22 drives the bending block 23 to move continuously downward, thereby moving the middle of the metal sheet downward. At this time, due to the restriction of the bending groove 13, the metal sheet is bent due to the continuous downward movement of the bending block 23.

[0034] It should also be noted that the hydraulic cylinder 22 is connected to a hydraulic power system, which is a solution already disclosed in the prior art. Therefore, this application will not elaborate on its specific structure here.

[0035] like Figure 3 As shown in this disclosure, there are four sets of movable positioning mechanisms 3 arranged in a rectangular pattern. Each set of movable positioning mechanisms 3 includes an electric push rod 31 fixedly mounted on the side of the gantry frame 21. The output shaft of the electric push rod 31 extends to the inside of the gantry frame 21. A movable plate 32 is fixedly mounted at the end of the output shaft of the electric push rod 31. A longitudinal slide groove 33 is provided on the inner side of the movable plate 32. Two parallel guide optical shafts 34 are fixedly mounted on the inner side of the longitudinal slide groove 33. A longitudinal slider 35 is slidably sleeved on the outer side of the two guide optical shafts 34. A connecting block 36 is rotatably connected to the side of the longitudinal slider 35 away from the electric push rod 31 via a pin. An L-shaped positioning push plate 37 is fixedly mounted at the bottom of the connecting block 36. A rubber pad 38 is adhered to the inner side of the L-shaped positioning push plate 37.

[0036] Therefore, after the metal sheet is placed on top of the support seat 12, the four electric push rods 31 drive the moving plate 32 to move inward. When the moving plate 32 moves inward, it drives the L-shaped positioning push plate 37 to move inward through the guide shaft 34, the longitudinal slider 35, and the connecting block 36. When the L-shaped positioning push plate 37 moves inward, it pushes the metal sheet through the rubber pads 38 until the four rubber pads 38 are respectively attached to the two ends of both sides of the metal sheet. At this time, the metal sheet is positioned. During the subsequent bending process, when the front and rear ends of the metal sheet are raised, the metal sheet pushes the L-shaped positioning push plate 37 through the rubber pads 38. The L-shaped positioning push plate 37 rotates around the pin on the connecting block 36, thus continuously adhering to the metal sheet. Simultaneously, the L-shaped positioning push plate 37 drives the longitudinal slider 35 to continuously move upward along the guide optical axis 34 inside the longitudinal groove 33 via the connecting block 36, thereby coordinating with the end of the metal sheet to move synchronously to reduce friction. Compared with the prior art, the L-shaped positioning push plate 37 can move synchronously with the end of the metal sheet during the bending process, thereby reducing friction. At the same time, the rubber pad 38, compared with hard objects, can further reduce friction noise and friction damage to ensure the quality of the sheet.

[0037] It should also be noted that any content not described in detail in this specification is prior art known to those skilled in the art.

[0038] Those skilled in the art should understand that the above embodiments are merely for illustrating the present disclosure and are not intended to limit the scope of the disclosure. Those skilled in the art can make other changes or modifications based on the above disclosure, and these changes or modifications still fall within the scope of the present disclosure.
