Description

Technical Field

[0001] The utility model relates to the technical field of bending machines, and specifically, to a bending machine. Background Art

[0002] A bending machine is a machine that can bend thin plates. During the use of the bending machine, the thin plate to be bent is placed on the workbench, and the thin plate is bent jointly by a bending lower die and a bending upper die. Due to its advantages such as simple operation, low cost, and fast response speed, the bending machine has been widely used.

[0003] However, in the existing bending machines, the lengths of the bending lower die and the bending upper die are generally fixed. When the length of the thin plate to be bent is greater than the lengths of the bending lower die and the bending upper die, the bending lower die and the bending upper die cannot bend all positions of the thin plate, resulting in a poor bending effect, so improvement is needed.

[0022] To further understand the content of the present utility model, the present utility model will be described in detail with reference to the accompanying drawings and embodiments. It should be understood that the embodiments are only for explaining the present utility model and not for limiting it.

[0023] The following is further described in detail with reference to the attached Figures 1 - 3 This embodiment will be further described in detail.

[0024] Please refer to Figures 1 - 3 , a bending machine in this embodiment includes a bottom plate 100. A fixing component for fixing a thin plate is provided on the bottom plate 100. The fixing component includes an upper bracket 110 provided on the bottom plate 100. A strip-shaped groove 112 is provided along the length direction of the upper bracket 110. A plurality of bending upper dies 113 with one end protruding and movable are provided in the strip-shaped groove 112. The fixing component further includes a lower bracket 120. A plurality of movable and detachable bending lower dies 123 are provided on the lower bracket 120. The lower bracket 120 is rotatably arranged. A movable fixing plate 140 is further provided on the bottom plate 100. The fixing plate 140 can extend into the space between the bending upper die 113 and the bending lower die 123.

[0025] In this embodiment, one side of the thin plate to be bent is extended into the space between the bending upper die 113 and the bending lower die 123, so that one side of the thin plate abuts against one side wall of the fixing plate 140. At this time, the rotation of the lower bracket 120 can drive the bending lower die 123 to rotate, so that the thin plate rotates around the protruding end of the bending upper die 113, thereby completing the bending operation on the thin plate;

[0026] Among them, through the movable settings of the bending lower die 123 and the bending upper die 113, when the length of the thin plate to be bent is greater than the lengths of the bending lower die 123 and the bending upper die 113, the adjacent bending lower die 123 and bending upper die 113 can be brought closer to form a bending lower die 123 and a bending upper die 113 with a longer length in combination, so as to adapt to the bending operation of a thin plate with a longer length;

[0027] Among them, through the movable setting of the fixing plate 140, when it is necessary to perform bending operations on different positions of the thin plate, that is, the side widths of the bent thin plate are different, it is possible to control the front-back movement of the fixing plate 140 between the bending upper die 113 and the bending lower die 123, and further adjust the distance between the thin plate extending into the bending lower die 123 and the bending upper die 113, so as to realize the bending of different positions of the thin plate.

[0028] Such as Figure 1As shown, in this embodiment, a plurality of first fixing holes 111 communicating with the strip-shaped grooves 112 are uniformly provided along the length direction of the upper bracket 110, and screws for fixing the bending upper die 113 are threadedly provided in the first fixing holes 111.

[0029] In this embodiment, the other end of the bending upper die 113 forms a sliding portion that moves within the strip-shaped groove 112. The screw is threadedly connected to the corresponding first fixing hole 111 and extends into the sliding portion, thereby realizing the fixation of the bending upper die 113 within the strip-shaped groove 112.

[0030] Among them, the distance between adjacent first fixing holes 111 is adapted to the bending upper die 113. That is, when the screws are threadedly connected to adjacent first fixing holes 111 to fix the bending upper die 113, two adjacent bending upper dies 113 can be attached, preferably forming a bending upper die 113 with a longer length.

[0031] As Figure 1 shown, in this embodiment, a plurality of second fixing holes 124 are uniformly provided along the length direction of the lower bracket 120, and screws for fixing the bending lower die 123 are provided in the second fixing holes 124.

[0032] In this embodiment, the bending lower die 123 can slide on the lower bracket 120. When the length of the thin plate to be bent is relatively long, adjacent bending lower dies 123 can be moved closer to each other, and screws are used to pass through the second fixing holes 124, thereby combining to form a bending lower die 123 with a longer length for bending the thin plate.

[0033] Among them, the distance between adjacent second fixing holes 124 is adapted to the bending lower die 123. That is, when the screws are threadedly connected to adjacent second fixing holes 124 to fix the bending lower die 123, two adjacent bending lower dies 123 can be attached, preferably forming a bending lower die 123 with a longer length.

[0034] As Figure 1 shown, in this embodiment, motor brackets 121 are oppositely provided on the bottom plate 100, a first servo motor 122 is provided on the motor brackets 121, and the output shaft of the first servo motor 122 is fixedly connected to one end of the lower bracket 120. The first servo motor 122 is started to drive the lower bracket 120 to rotate.

[0035] In this embodiment, through the arrangement of the motor brackets 121, the first servo motor 122 can be installed on the bottom plate 100. When the first servo motor 122 is started, it can drive the lower bracket 120 to rotate, and then make the bending lower die 123 rotate, cooperating with the fixed bending upper die 113 to perform a bending operation on the thin plate extending from the fixing plate 140.

[0036] As Figures 1 - 2As shown, in this embodiment, a detachable induction plate 210 is provided on the output shaft of the first servo motor 122, and a proximity switch 201 for restricting the rotation angle of the induction plate 210 is provided on the bottom plate 100.

[0037] In this embodiment, a through hole for the output shaft of the first servo motor 122 to pass through is provided on the induction plate 210. The output shaft of the first servo motor 122 passes through the through hole to achieve the fixed installation of the induction plate 210 thereon. During actual use, locking nuts are oppositely provided on the output shaft of the first servo motor 122, and the locking nuts are respectively provided on both sides of the induction plate 210. Thus, when the locking nuts squeeze and fix the induction plate 210, the induction plate 210 can rotate with the output shaft of the first servo motor 122. During actual use, a PLC controller (not shown in the figure) is also provided on the bottom plate 100. The first servo motor 122 and the proximity switch 201 are electrically connected to the PLC controller. When the first servo motor 122 drives the induction plate 210 to rotate and the induction plate 210 contacts the proximity switch 201, the PLC controller controls the first servo motor 122 to stop rotating and controls the first servo motor 122 to rotate and reset, so as to prevent the bending lower die 123 from rotating beyond the set angle.

[0038] Among them, an installation frame 200 for installing the proximity switch 201 is provided on the bottom plate 100.

[0039] As Figures 1 - 3 shown, in this embodiment, a track 130 is provided on the upper end surface of the bottom plate 100 along its front-rear direction. Along the extending direction of the upper end surface of the track 130, a fixed bracket 132, a front baffle 133, and a rear baffle 310 are sequentially provided. At one end surface of the track 130, clamping grooves 301 are oppositely provided along its extending direction. A movable mounting seat 320 is provided between the front baffle 133 and the rear baffle 310. A clamping block extending into the clamping groove 301 is provided on the mounting seat 320. A second servo motor 131 is provided on the fixed bracket 132. A lead screw passing through the fixed bracket 132, the front baffle 133, and the rear baffle 310 is provided at the output end of the second servo motor 131. The lead screw is threadedly passed through the mounting seat 320. The rotation of the lead screw is used to drive the mounting seat 320 to move on the track 130. The fixing plate 140 is detachably provided on the mounting seat 320.

[0040] In this embodiment, by sliding the clamping block in the corresponding clamping groove 301, the clamping block is restricted by the clamping groove 301. When the second servo motor 131 is started, the lead screw rotates, and then the mounting seat 320 moves along the axial direction of the lead screw, thereby driving the fixing plate 140 to move accordingly.

[0041] Among them, bearings for rotatably connecting the lead screw are provided inside the front baffle 133 and the rear baffle 310. Through the settings of the front baffle 133 and the rear baffle 310, the moving distance of the mounting seat 320 is limited, that is, it can only move between the front baffle 133 and the rear baffle 310 and will not escape from the track 130;

[0042] Among them, the fixing plate 140 is detachably arranged on the mounting seat 320 by screws. When the fixing plate 140 is damaged or deformed, the replacement operation can be carried out by removing the screws.

[0043] Working principle: When bending the thin sheet is required, first, start the second servo motor 131 to drive the fixing plate 140 to move to a suitable position. Then, move the adjacent bending lower die 123 and the adjacent bending upper die 113 closer to adapt to the length of the thin sheet. Then, fix the bending lower die 123 and the bending upper die 113 with screws. Secondly, insert one end of the thin sheet into the gap between the fixing plate 140 and the bending upper die 113, and start the first servo motor 122 to drive the bending lower die 123 to rotate to bend the other end of the thin sheet.

[0044] In summary, the above are only the preferred embodiments of the present invention. All equivalent changes and modifications made according to the scope of the patent application of the present invention shall fall within the scope covered by the patent of the present invention.
