[0001] This utility model belongs to the field of metal cutting technology, and specifically relates to a cutting and positioning mechanism for metal sheets. Background Technology

[0002] Metal sheets are widely used in various fields in people's daily lives. When using them, metal sheets need to be processed and cut into various sizes as needed.

[0003] The utility model application with application number CN202421080930.8 (publication number CN222449236U) relates to an automatic feeding metal cutting machine. The machine housing has a positioning mechanism inside, a metal plate inside the positioning mechanism, an adjustment mechanism inside the machine housing, a cutting mechanism at the bottom of the adjustment mechanism, and a collection box at the bottom of the inner wall of the machine housing. The positioning mechanism includes a conveying roller fixed to the left side of the top of the base.

[0004] In production, batches of boards are usually fed. The aforementioned patent lacks a positioning component for feeding batches of boards, which can lead to inconsistent feeding positions and affect processing efficiency. Utility Model Content

[0005] In view of this, the present invention provides a cutting and positioning mechanism for metal sheets to solve the technical problem that the lack of positioning components when feeding batches of sheets leads to inconsistent feeding positions and affects processing efficiency.

[0006] This utility model is implemented as follows:

[0007] This utility model provides a cutting and positioning mechanism for metal sheets, which has a worktable. A loading platform is provided on one side of the worktable. Two support plates are provided on the loading platform and are synchronously slidably connected by a positioning component. Each support plate is fixedly installed with a vertical plate.

[0008] Positioning plates are fixedly installed on the top wall of each upright plate. Each positioning plate is provided with a separating component for separating the plates. Each upright plate is provided with a feeding mechanism for feeding the plates on the opposite side. An abutment plate is provided between the two support plates to drive the plates to move vertically.

[0009] Based on the above technical solution, the metal sheet cutting and positioning mechanism of this utility model can be further improved as follows:

[0010] Furthermore, a limit plate is fixedly installed on the opposite side of the right end of each positioning plate, and a through groove is opened on each positioning plate. The separating component includes a separating piece that is slidably connected relative to the through groove, and a first telescopic cylinder that drives the separating piece to move horizontally. The end of the separating piece is spike-shaped.

[0011] Furthermore, a bent plate is fixedly installed on the positioning plate above the through groove, the fixed end of the first telescopic cylinder is fixedly connected to the bottom wall of the bent plate, and the separating plate is fixedly installed at the movable end of the first telescopic cylinder.

[0012] Furthermore, the feeding mechanism includes a belt support block fixedly installed on the vertical plate, and both sides of the belt support block are provided with sliding sleeves rotatably connected to the vertical plate;

[0013] Each of the sliding sleeves is fitted with a fixed pulley, and the two pulleys are connected by a belt for transmission.

[0014] Furthermore, two fixed seats located on the outside of the vertical plate are symmetrically fixedly installed on one end of the loading platform away from the workbench. A transmission rod is rotatably connected to both fixed seats, and two sliding sleeves on the same side are slidably connected to the transmission rod.

[0015] Furthermore, a fixed end of a second telescopic cylinder is fixedly installed in the middle of the bottom wall of the loading platform, and the movable end of the second telescopic cylinder extends upward and slides through the loading platform to be slidably connected thereto. The abutment plate is fixedly installed on the top wall of the movable end of the second telescopic cylinder.

[0016] Compared with the prior art, the beneficial effects of the metal sheet cutting and positioning mechanism provided by this utility model are:

[0017] By setting a sliding connection support plate, the width of the plate can be adjusted by the positioning plate, which abuts against the front and rear side walls of the plate to align the plates, and the limiting plate assists in aligning the right wall of the plate.

[0018] By setting up a separator component, the bottommost board is separated from the other boards and then falls onto the feeding mechanism.

[0019] By setting a vertically movable abutment plate, the vertical height of the plate can be adjusted so that the position to be separated corresponds to the separating plate, and the separated plate can be moved to the feeding mechanism.

[0020] By setting up a feeding mechanism, the positioned sheet material is moved to the worktable for cutting;

[0021] With the above settings in place, this mechanism ensures that each piece of material in the same batch is fed into the same position, eliminating the need for further adjustments. Attached Figure Description

[0036] Example 1

[0037] like Figure 1-5 As shown, this utility model provides a cutting and positioning mechanism for metal sheets, which has a worktable 1. A loading platform 2 is provided on one side of the worktable 1. Two support plates 21 are provided on the loading platform 2 through a positioning component and are slidably connected synchronously. Each support plate 31 is fixedly installed on the support plate 21.

[0038] Positioning plates 22 are fixedly installed on the top wall of each upright plate 31. Each positioning plate 22 is provided with a partition component for separating the plates. Each upright plate 31 is provided with a feeding mechanism for feeding the plates on the opposite side. An abutment plate 42 is provided between the two support plates 21 to drive the plates to move vertically.

[0039] Optionally, in the above technical solution, a limiting plate 221 is fixedly installed on the opposite side of the right end of the positioning plate 22, and a through groove 23 is opened on the positioning plate 22. The separating component includes a separating piece 24 that is slidably connected relative to the through groove 23, and a first telescopic cylinder 25 that drives the separating piece 24 to move horizontally. The end of the separating piece 24 is spike-shaped.

[0040] Optionally, in the above technical solution, a bending plate 26 is fixedly installed on the positioning plate 22 and above the through groove 23, the first telescopic cylinder 25 is fixedly connected to the bottom wall of the bending plate 26, and the separation plate 24 is fixedly installed at the movable end of the first telescopic cylinder 25.

[0041] The separator is provided in four groups, which are arranged in a rectangular structure on the same plane. The ends of the separator pieces 24 on the two positioning plates 22 are arranged opposite each other.

[0042] Optionally, in the above technical solution, the feeding mechanism includes a belt support block 33 fixedly installed on the vertical plate 31, and both sides of the belt support block 33 are provided with sliding sleeves 34 rotatably connected to the vertical plate 31.

[0043] Each sliding sleeve 34 is fitted with a fixed pulley 35, and the two pulleys 35 are connected to a belt 32 for transmission. Optionally, in the above technical solution, two fixed seats 36 located on the outside of the vertical plate 31 are symmetrically fixedly installed on the loading platform 2 at the end away from the worktable 1. The two fixed seats 36 are rotatably connected to a transmission rod 37, and the two sliding sleeves 34 on the same side are slidably connected to the transmission rod 37.

[0044] The transmission rod 37 passes through the vertical plate 31 and is slidably connected to it.

[0045] Optionally, in the above technical solution, the fixed end of the second telescopic cylinder 41 is fixedly installed in the middle of the bottom wall of the loading platform 2, the movable end of the second telescopic cylinder 41 extends upward, passes through the loading platform 2 and is slidably connected thereto, and an abutment plate 42 is fixedly installed on the top wall of the movable end of the second telescopic cylinder 41.

[0046] Furthermore, two slide rails 51 are fixedly installed on the loading platform 2, and two sliders 52 are slidably connected to each slide rail 51. Support plates 21 are fixedly installed on the corresponding two sliders 52. A double-ended lead screw 53 parallel to the slide rail 51 is rotatably connected between one slide rail 51 and the second telescopic cylinder 41. Screw blocks 54 are fitted on the threads on both sides of the double-ended lead screw 53. The screw blocks 54 are fixedly installed on the bottom wall of the support plate 21 on the same side. A drive motor B55 for driving the double-ended lead screw 53 to rotate is fixedly installed on the loading platform 2.

[0047] Furthermore, a drive motor A38 is fixedly installed on the loading platform 2 and connected to the end of the transmission rod 37 via a coupling.

[0048] Among them, drive motor B55 can rotate clockwise and counterclockwise (to bring the support plates 21 closer to each other or further apart), while drive motor A38 can only rotate clockwise (to feed material in one direction).

[0049] The bottom of the limiting plate 221 is located above the top of the belt 32. The height gap between the two is less than the thickness of a plate and they do not touch, which prevents damage to the belt 32 and can limit the plate.

[0050] The inner top wall of belt 32 abuts against the top wall of belt support block 33, which facilitates the bearing of the plate; the transmission rod 37 is not a cylindrical structure, which facilitates the rotation of sliding sleeve 34; the length of vertical plate 31 is greater than the length of support plate 21, and the length of transmission rod 37 is greater than the length of slide rail 51.

[0051] Among them, the two pulleys 35 on a set of feeding components can be divided into a driving pulley and an idler pulley, with the driving pulley being the one closer to the worktable 1; and a fixed seat 36 is also provided in the middle to support the transmission rod 37, which is suitable for situations where the transmission rod 37 is too long.

[0052] Working principle:

[0053] In the initial state, the movable end of the first telescopic cylinder 25 is fully retracted, the abutment plate 42 is located at the separation plate 24, and the distance between the two support plates 21 is at its maximum.

[0054] Place the batch of metal sheets to be cut onto the abutment plate 42, with the right wall abutting against the limiting plate 221. At this time, move the two support plates 21 inward simultaneously until the positioning plate 22 abuts against the front and rear walls of the metal sheet, positioning the metal sheet in the middle of the abutment plate 42 (then move the two support plates 21 to move the positioning plate 22 slightly outward, so that there is a certain gap between the positioning plate 22 and the metal sheet, which facilitates the metal sheet to move up and down).

[0055] At this time, the second telescopic cylinder 41 causes the abutment plate 42 to move the metal plate slightly downward. After moving to the appropriate position, the metal plate at the bottom is separated from the metal plate at the top by the separating component. Then, the movable end of the second telescopic cylinder 41 is retracted, causing the abutment plate 42 to move down to the lowest end.

[0056] At this time, the bottom metal plate is located on the two belts 32 (the support plate 21 also drives the feeding assembly to move). The feeding assembly drives the metal plate to move onto the worktable 1. When the metal plate is completely moved onto the worktable 1, it is cut.

[0057] Then, the abutment plate 42 is moved upward to abut against the metal plate at the bottom, and the separation plate 24 is reset to the initial state. The above operation of the abutment plate 42 and the separation plate 24 is repeated. After the metal plate on the worktable 1 is cut and removed, the feeding assembly is started again to move the plate onto the worktable 1.

[0058] The support plate 21 moves as follows: the drive motor B55 is started to drive the screw block 54 to rotate, thereby causing the two screw blocks 54 to drive the support plate 21 and move closer or further away from it along the slide rail 51 via the slider 52.

[0059] The working method of the separator is as follows: when the second telescopic cylinder 41 drives the abutment plate 42 so that the top wall of the lowest plate is located at the position corresponding to the tip of the separator 24, the four first telescopic cylinders 25 are activated so that their movable ends are fully extended, driving the separator 24 to insert between the lowest plate and the adjacent plate. That is, the lowest plate is located below the separator 24, and the remaining plates are located above the separator 24. The four separators 24 support the bottom four points of the upper plate to ensure the stability of the plate support.

[0060] The feeding assembly works as follows: the drive motor A38 is started, which drives the transmission rod 37 to rotate clockwise in place on the fixed seat 36. The rotation of the transmission rod 37 drives the sliding sleeve 34 to rotate the pulley 35 clockwise, thereby causing the two belts 32 to rotate simultaneously, driving the plate to move towards the worktable 1.

[0061] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
