Description

Technical Field

[0001] This utility model relates to the field of metal sheet processing technology, and in particular to a sheet bending fixture. Background Technology

[0002] When assembling electrical control cabinets or control panels, bending plates are required, necessitating the bending of existing straight plates. Existing plate bending devices use hydraulic levers to bend the plates, but these are unsuitable for multiple bends. For processing irregularly shaped curved plates, existing bending devices cannot bend the same plate multiple times, and they are only suitable for narrow-width plates. When bending wider plates, they encounter problems such as difficulty in positioning and skewed folds.

[0003] Therefore, the bending device needs to be improved to enhance the bending effect of wide sheet metal. Utility Model Content

[0004] The purpose of this utility model is to provide a plate bending fixture that can be applied to large plates, meet the bending requirements of irregularly shaped plates, and improve the bending effect.

[0005] To achieve the above-mentioned utility model objectives, this utility model provides a plate bending fixture, including a connecting plate, a connecting beam, a lifting cylinder, a pressing mechanism, a base, and a positioning mechanism;

[0006] The lifting cylinder is connected to the connecting plate via the connecting beam, and the connecting plate is provided with the pressing mechanism;

[0007] The pressing mechanism includes a pressing plate and a mounting plate. The mounting plate is provided with a mounting groove, and the pressing plate is detachably connected to the mounting groove by a first fastener.

[0008] The base is provided with a material support seat, and the top of the material support seat is provided with a folding groove;

[0009] The positioning mechanism includes a positioning cylinder, a moving component, and a positioning plate. The positioning plate is connected to the moving component, and the moving component is connected to the positioning cylinder. The end of the positioning plate is provided with a top material head, which faces the material support seat.

[0010] As a further improvement of the utility model, the pressing mechanism also includes a reinforcing plate. The pressing plate is provided with a first connecting hole, the reinforcing plate is provided with a second connecting hole, the mounting plate is provided with a fixing opening, and a second fastener passes through the first connecting hole and the second connecting hole and is fixed in the fixing opening.

[0011] Furthermore, the reinforcing plate is provided with a protruding abutment block, which is located on one side that is pressed tightly against the pressure plate.

[0012] As a further improvement to the utility model, a linear guide rail is provided between the connecting beam and the connecting plate.

[0013] As a further improvement of the utility model, the bottom of the material support is provided with a fixing plate, which is detachably fixed to the base by a third fastener.

[0014] As a further improvement of the utility model, the connecting plates are arranged in parallel with one or more of the pressing mechanisms.

[0015] This utility model discloses a plate bending fixture. The plate is placed on a support seat, and a positioning cylinder controls a positioning plate to move closer to the support seat. The top material head presses against the side of the plate, and the plate is clamped between the top material head and the operator's hand. Then, the pressure plate descends under the action of a lifting cylinder, pressing the lower part of the plate into the bending groove for bending. The pressure plate quickly returns to its original position under the action of the lifting cylinder, and the positioning plate returns to its original position under the action of the positioning cylinder. The plate is then removed, and the remaining bending areas are placed on the bending groove. The above steps are repeated.

[0016] The advantages of this plate bending fixture compared to existing technologies are as follows:

[0017] (1) The positioning plate can position the board material to prevent the board material from shifting when the pressure plate presses down, which would cause the folded edge to be crooked and affect the bending effect;

[0018] (2) With the pressing plate pressing down, the sheet metal is bent along the folding groove, which can ensure the flatness of the folded edge and improve the bending quality. Attached Figure Description

[0021] Figure 3 This is a partially enlarged schematic diagram of a plate bending fixture according to the present invention. Detailed Implementation

[0022] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings.

[0023] like Figure 1 As shown, a plate bending fixture of this utility model includes a connecting plate 1, a connecting beam 11, a lifting cylinder 2, a pressing mechanism 3, a base 4, and a positioning mechanism 5.

[0024] The lifting cylinder 2 is connected to the connecting plate 1 via the connecting beam 11, and the connecting plate 1 is equipped with a pressing mechanism 3;

[0025] like Figure 2 As shown, the pressing mechanism 3 includes a pressing plate 31 and a mounting plate 33. The mounting plate 33 is provided with a mounting groove 331. The pressing plate 31 is detachably connected to the mounting groove 331 by a first fastener 34.

[0026] Under the action of the lifting cylinder 2, the pressure plate 31 descends and presses down on the target material 6. The pressure plate 31 can be quickly disassembled and assembled using the first fastener 34 to adapt to different material bending requirements. A linear guide rail 12 is provided between the connecting beam 11 and the connecting plate 1. The linear guide rail 12 plays a guiding role, so that the connecting plate 1 always maintains the same linear lifting and lowering, which can achieve the effect of positioning the pressing position of the pressure plate 31.

[0027] The pressing mechanism 3 also includes a reinforcing plate 32. The pressing plate 31 is provided with a first connecting hole 311, the reinforcing plate 32 is provided with a second connecting hole 321, the mounting plate 33 is provided with a fixing opening 331, and the second fastener 35 passes through the first connecting hole 311 and the second connecting hole 321 and is fixed in the fixing opening 331.

[0028] The pressure plate 31 is clamped between the mounting plate 33 and the reinforcing plate 32. The reinforcing plate 32 is provided with a protruding abutment block 322. The abutment block 322 is located on the side that is pressed tightly against the pressure plate 31, which further positions and fixes the pressure plate 31 to prevent the pressure plate 31 from loosening when pressing the material.

[0029] The base 4 is provided with a material support seat 42, and the top of the material support seat 42 is provided with a folding groove 43; the bottom of the material support seat 42 is provided with a fixing plate 41, and the fixing plate 41 is detachably fixed to the base 4 by a third fastener 44. The sheet material 6 is placed on the folding groove 43, and the material support seat 42 with different sizes of folding groove 43 can be replaced according to different folding requirements by using the pressure plate 31.

[0030] The positioning mechanism 5 includes a positioning cylinder 51, a moving component 52, and a positioning plate 53. The positioning plate 53 is connected to the moving component 52, and the moving component 52 is connected to the positioning cylinder 51. The end of the positioning plate 53 is provided with a top material head 531, which faces the material support seat 42.

[0031] This utility model discloses a plate bending fixture. The plate 6 is placed on a support base 42. A positioning cylinder 51 controls a positioning plate 53 to move closer to the support base 42. A top-loading head 531 presses against the side of the plate 6, clamping the plate 6 between the top-loading head 531 and the operator's hand. Then, a pressure plate 31 descends under the action of a lifting cylinder 2, pressing a portion of the plate 6 below into a bending groove 43 for bending. The pressure plate 31 quickly resets under the action of the lifting cylinder 2, and the positioning plate 53 resets under the action of the positioning cylinder 51. The plate 6 is then removed, and the remaining bending areas are placed on the bending groove 43. The above steps are repeated.

[0032] The moving component 52 can be an existing ball screw assembly. The screw is driven to rotate by a motor, which causes the positioning plate 53 connected to it to move linearly, thereby adjusting the position of the top material head 531 to match the positioning position of the plate 6.

[0033] The connecting plate 1 has one or more pressing mechanisms 3 arranged in parallel. For plates with a large width, multiple pressing plates 31 can be lowered at the same time to enhance the pressing effect and avoid uneven force on the folded edge, which would affect the flatness of the folded edge.

[0034] The preferred embodiments of this utility model have been described in detail above, but this utility model is not limited to the embodiments described. Those skilled in the art can make various equivalent modifications or substitutions without departing from the spirit of this utility model, and these equivalent modifications or substitutions are all included within the scope defined by the claims of this application.
