Description

Technical Field

[0001] The utility model relates to the technical field of plate stainless steel plate processing equipment, in particular to a stainless steel plate bending machine capable of ensuring bending accuracy, in particular capable of ensuring the accuracy of the bending angle. Background Art

[0002] Stainless steel plates with a thickness of 2.0-4.0 mm can be used as elevator car panels after bending. However, it is difficult to bend stainless steel plates within this thickness range, and the bending angle is relatively large, so that the obtained car panels have relatively large chamfers, which affects the assembly tightness and aesthetics of adjacent car panels.

[0003] For example, the bending device disclosed in the utility model patent with publication number CN218224192U and titled "A device for quickly bending the edge of a steel plate" includes a main support, a bending support plate and a folding mechanism, wherein a bending support plate is fixedly installed on the top of the main support, and the folding mechanism is fixedly installed on the main support and the bending support plate; the folding mechanism includes a clamping cylinder, a long pressure strip, a locking nut, a cylinder hinge seat, a bending cylinder, a fixed shaft seat, a bending strip, a swing shaft block and a strip hinge seat, and two sets of clamping cylinders are symmetrically fixedly installed on the bottom end of the bending support plate, and the cylinder rods of the two sets of clamping cylinders pass through the bending support. The plate is inserted on the long pressure strip, and the cylinder rod ends of the two groups of pressing cylinders are threadedly covered with locking nuts, and the bottom ends of the locking nuts are tightly attached to the long pressure strip, and two groups of cylinder hinge seats are symmetrically fixedly installed on the main body bracket, and a group of bending cylinders are swingably installed on each group of cylinder hinge seats, and two groups of fixed shaft seats are symmetrically fixedly installed on both sides of the bending support plate, and two groups of swing shaft blocks are symmetrically fixedly installed at both ends of the bending strip, and the two groups of swing shaft blocks are rotatably installed on the two groups of fixed shaft seats respectively, and two groups of strip board hinge seats are symmetrically fixedly installed on the bending strip, and the ends of the cylinder rods of the bending cylinders are hinged to the strip board hinge seats.

[0004] Although the above structure can be used to bend relatively thin stainless steel plates or other steel plate materials with relatively narrow bending edges more efficiently and conveniently, this type of device is difficult to ensure the bending accuracy when bending stainless steel plates with larger thickness and wider bending edges, specifically the accuracy and uniformity of the bending angles.

[0005] Additionally, the long pressure strip of this structure is pressed against the surface of the stainless steel plate near the bending position, which can easily cause damage to the surface of the stainless steel plate during the pressing process, especially the stainless steel plate that has been mirror-finished, thereby affecting the plate surface quality. Utility Model Content

[0006] The purpose of the present application is to overcome at least one of the above-mentioned technical problems and to provide a stainless steel plate bending machine.

[0007] To achieve the above technical objectives, one aspect of the utility model provides a stainless steel plate bending machine, comprising a horizontal frame beam and a vertical frame beam extending along the x-axis and y-axis directions respectively, and also comprising:

[0008] A first supporting platform, wherein the first supporting platform is installed through the horizontal beam, and a first supporting surface of the first supporting platform is transitionally connected to an end surface of the end through a first contoured surface;

[0009] A second supporting platform, the second supporting platform comprising a second supporting surface, and the second supporting platform is disposed at the end of the first supporting platform in a flippable manner;

[0010] A first clamping mechanism, the first clamping mechanism comprising a first clamping roller group which can be lifted and lowered and mounted on the vertical frame beam;

[0011] A second pressing mechanism, the second pressing mechanism comprising a second pressing roller group which can be lifted and lowered and installed on the second supporting platform;

[0012] Wherein, when the second supporting platform is in a horizontal state, the second supporting surface is flush with the first supporting surface; when the second supporting platform is in a flipped state, the second supporting surface is flush with the end surface.

[0013] By means of the above structure, since the second supporting surface is flush with the first supporting surface before flipping and flush with the end surface after flipping, and both sides of the bending position of the stainless steel plate are always clamped by the first clamping mechanism and the second clamping mechanism, the bending part of the stainless steel plate is always against the first profiling surface, and the first profiling surface, the second supporting surface and the end surface are matched to obtain a bending inner angle with the same shape and size as the first profiling surface, thereby obtaining a bent stainless steel plate with a bending angle of high precision and relatively uniform specifications.

[0014] At the same time, the first pressing roller set and the second pressing roller set are both roller pressing structures, which can avoid damage to the surface of the stainless steel plate during pressing and ensure the decorative effect of the stainless steel plate.

[0015] Furthermore, this bending method can also be applied to situations where the width of the bending portion is relatively large.

[0016] As a preferred embodiment, the first contoured surface is a quarter arc surface with a diameter of 2.0-3.0 mm.

[0017] As a preferred embodiment, the stainless steel plate bending machine also includes a bending angle profiling module, which can be installed on the vertical frame beam in a lifting manner, and the bending angle profiling module has a second profiling surface that matches the first profiling surface, and the second profiling surface is located directly above the first profiling surface.

[0018] As a preferred implementation, after the bending angle profiling module is lowered into place, the central axis of the second profiling surface coincides with the central axis of the first profiling surface.

[0019] As a preferred implementation, the bending angle profiling module further includes an abutting arc surface, and a transition arc surface connecting the second profiling surface and the abutting arc surface.

[0020] As a preferred implementation, the bending angle profiling module can be lowered synchronously with the first clamping mechanism, and continue to be lowered after the first clamping mechanism is lowered into place.

[0021] As a preferred embodiment, the vertical frame beam is a lifting gantry beam, which is arranged across the first supporting platform; the bending angle profiling module is fixedly installed on the bottom surface of the gantry beam of the vertical frame beam, and the first clamping roller group is installed on the bottom surface of the gantry beam of the vertical frame beam through the first cylinder group.

[0022] As a preferred implementation, the second pressing mechanism further includes a guide roller group arranged on a side of the second pressing roller group close to the first supporting platform.

[0023] As a preferred implementation, the second pressing mechanism further includes a pressing block group arranged on a side of the second pressing roller group away from the first supporting platform.

[0024] To sum up, the utility model has at least the following advantages: the bent stainless steel plate has a bending angle with high precision and relatively uniform specifications, which avoids damage to the surface of the stainless steel plate, ensures the decorative effect of the stainless steel plate, and can also be applied to situations where the width of the bent part is larger.

DETAILED DESCRIPTION

[0033] In order to enable those skilled in the art to better understand the technical solutions in the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of this application.

[0034] Example 1: Reference Figure 1 A stainless steel plate bending machine is shown, comprising a horizontal frame beam 1 and a vertical frame beam 2 extending along the x-axis and y-axis directions respectively. The horizontal frame beam 1 is a frame structure of the prior art, suitable for providing support and installation space; the vertical frame beam 2 is a lifting gantry beam of the prior art, arranged across the first support platform 3, for example, its gantry beam can be lifted and lowered in the y-axis direction under the drive of a screw system.

[0035] The stainless steel plate bending machine further comprises: a first supporting platform 3 , a second supporting platform 4 , a first clamping mechanism 5 , a second clamping mechanism 6 , and a turning mechanism 8 .

[0036] Reference Figure 2As shown, the first support platform 3 is bolted or welded to the horizontal frame beam 1. The first support platform 3 has a first support surface 32 capable of placing the stainless steel plate 9, an end surface 33 at the end, and a first contour surface 31 connecting the first support surface 32 and the end surface 33. The first contour surface 31 is a quarter arc surface with a diameter of 2.0-3.0 mm.

[0037] Reference Figure 3 As shown, the second support platform 4 includes a second support surface 41, and the second support platform 4 is connected to the end of the first support platform 3 through a flip mechanism 8. Both sides of the second support platform 4 extend toward the first support platform 3 to form a pair of connecting plates with mounting holes, and a pair of mounting shafts are welded on both sides of the end of the first support platform 3, and the mounting holes of the connecting plates are mounted on the mounting shafts through rotating bearings, so that the second support platform 4 can rotate relative to the first support platform 3.

[0038] The flipping mechanism 8 includes a flipping drive unit and a flipping guide unit. The flipping drive unit is not shown in the figure, and it can be a bending cylinder connected to the bottom of the second support platform 4 through a cylinder hinge seat as disclosed in CN218224192U. The flipping guide unit includes a pair of sliders welded on both sides of the second support platform 4 and a pair of arc tracks installed through the horizontal frame beam 1. The sliders can slide in the arc tracks to guide the flipping of the second support platform 4. When the second support platform 4 is in a horizontal state, that is, when the bending cylinder is in an extended state, the second support surface 41 is flush with the first support surface 31; when the second support platform 4 is in a flipping state, that is, after the bending cylinder is retracted, the second support surface 41 is flush with the end surface 33.

[0039] Replay Figure 1 The first pressing mechanism 5 includes a first pressing roller set, which is a roller set in the prior art. Its setting position in the x-axis direction is close to the first contour surface 31, and its setting position side in the y-axis direction is located above the first support surface 32. The first pressing roller set is fixedly installed on the bottom surface of the gantry beam, so that it can rise and fall with the rise and fall of the gantry beam to press the stainless steel plate 9.

[0040] Reference Figure 4 As shown, the two sides of the second support platform 4 extend upward to form a pair of mounting plates 42, and the pair of mounting plates are connected by a top plate 43. The second pressing mechanism 6 includes a second pressing roller set 61, which is a roller set in the prior art and is installed on the inner wall of the top plate 43 so as to be able to rise and fall through a second cylinder set 64. Preferably, a guide groove suitable for guiding the second pressing roller set 61 to rise and fall is provided on the inner wall of the mounting plate 42.

[0041] As a preferred embodiment, the second clamping mechanism 6 further includes a guide roller group 62 arranged on the side of the second clamping roller group 61 close to the first support platform 3, and a pressure block group 63 arranged on the side of the second clamping roller group 61 away from the first support platform 3. The guide roller group 62 is a roller group of the prior art. The pressure block group 63 includes a plurality of telescopic gas rods with pressure blocks installed on their heads.

[0042] When bending, first send the stainless steel plate 9 to a position where part of it is located on the first supporting platform 3 and part of it is located on the second supporting platform 4, and make the bending part be located on the first contoured surface 31; then, drop the first clamping roller group to fix the plate surface of the stainless steel plate 9, and drop the second clamping roller group 61 and the pressing block group 63 to fix the bent part of the stainless steel plate 9; then, drive the flipping mechanism 8 to flip the second supporting platform 4; finally, after the bending is completed, reset the first clamping mechanism 5 and the second clamping mechanism 6, take out the bent stainless steel plate, and then reset the second supporting platform 4.

[0043] Since the second support surface 41 is flush with the first support surface 31 before flipping and is flush with the end surface 33 after flipping, and the two sides of the bending position of the stainless steel plate 9 are always clamped by the first clamping mechanism 5 and the second clamping mechanism 6, the bending part of the stainless steel plate 9 always abuts against the first profiling surface 31, and the first profiling surface 31, the second support surface 41 and the end surface 33 cooperate to obtain the bending inner angle with the same shape and size as the first profiling surface 31, so that the bent stainless steel plate can have a bending angle with high precision and relatively uniform specifications. At the same time, the first clamping roller set and the second clamping roller set 61 are both roller clamping structures, so that the surface of the stainless steel plate 9 can be prevented from being damaged by the first clamping mechanism 5 during clamping, and the decorative effect of the stainless steel plate 9 can be ensured. Furthermore, this bending method can also be applied to the case where the width of the bending part is large.

[0044] Embodiment 2: Embodiment 2 differs from Embodiment 1 in that, referring to Figure 5 , Figure 6 As shown, the bending angle profiling module 7 is also included. The bending angle profiling module 7 can be installed on the vertical frame beam 2 in a synchronous manner with the first clamping mechanism 5, and continues to descend after the first clamping mechanism 5 is lowered into place. The bending angle profiling module 7 includes a second profiling surface 71 matched with the first profiling surface 31, abutting cambered surface 72, and a transition cambered surface 73 connecting the second profiling surface 71 and the abutting cambered surface 72. The second profiling surface 71 is located directly above the first profiling surface 31. When the bending angle profiling module 7 is lowered into place, the second profiling surface 71 coincides with the center axis of the first profiling surface 31. The abutting cambered surface 72 is a half-circular arc surface, and the transition cambered surface 73 is a concave circular arc surface.

[0045] Specifically, the bending angle profiling module 7 is fixedly installed on the bottom surface of the gantry beam of the vertical frame beam 2 by screwing or welding, so that the bending angle profiling module 7 can be synchronously lifted and lowered with the gantry beam with the first clamping roller group. At the same time, in this embodiment, the first clamping roller group is installed on the bottom surface of the gantry beam of the vertical frame beam 2 through the first cylinder group 52.

[0046] When bending, the stainless steel plate 9 is first sent to a position where part of it is located on the first supporting platform 3 and part of it is located on the second supporting platform 4, and the bending part is located on the first profiling surface 31; then, the gantry beam is lowered, and at the same time, the first pressing roller group is driven to fall by the first cylinder group 52 to fix the plate surface part of the stainless steel plate 9. At this time, the bending angle profiling module 7 has not yet contacted the stainless steel plate 9; then, the second pressing roller group 61 and the pressing block group 63 are lowered to fix the bent part of the stainless steel plate 9; then, the turning mechanism 8 is driven to turn the second supporting platform 4 over, and the gantry beam It moves downward so that the abutting arc surface 72 contacts the bent part of the stainless steel plate 9 without pressure, and the first cylinder 52 is recovered so that the first clamping roller group can adapt to the lowering of the height of the gantry beam while clamping; then, when the bending is completed, the inner angle of the bending part of the stainless steel plate 9 abuts against the first profiling surface 31, and the outer angle of the bending abuts against the second profiling surface 71, so that the bending angle of the bent stainless steel plate is obtained by profiling under the action of the two; finally, the first clamping mechanism 5 and the second clamping mechanism 6 are reset, the bent stainless steel plate is taken out, and then the second supporting platform 4 is reset.

[0047] The vertical beam 2, the second supporting platform 4, the first clamping mechanism 5, the second clamping mechanism 6, and the turning mechanism 8 of the embodiment of the present application are all electrically controlled by a control system of the prior art.
