DETAILED DESCRIPTION
[0018] In order to further understand the content, features and effects of the present invention, the following embodiments are given as examples and described in detail with reference to the accompanying drawings.
[0019] The structure of the present invention is described in detail below in conjunction with the accompanying drawings.
[0020] See also Figures 1 to 9 , a thin metal plate grooving processing mechanical device provided by an embodiment of the present invention comprises a base 1, a plurality of supporting legs 2 are fixedly connected to the lower side of the base 1, a panel 3 is fixedly connected to the upper side of the base 1, a first baffle 4 is installed on the side of the base 1 away from the panel 3, two symmetrical first sliding rods 5 are fixedly connected between the first baffle 4 and the panel 3; a first sliding seat 6 is slidably connected to the first sliding rod 5, and a first fixed seat 7 is installed on the upper side of the first sliding seat 6; A shearing assembly is installed on the first fixing seat 7, and a driving member is installed on one side of the shearing assembly.
[0021] The above scheme is adopted: when in use, during the grooving process of thin metal sheets, the staff adjusts the sliding position of the first sliding seat 6 on the first sliding rod 5, and synchronously drives the first fixed seat 7 and the shearing assembly to move, so as to adapt to the specific length of the part of the thin metal sheet that needs to be sheared, thereby facilitating the grooving process of the sheet edge. Subsequently, the thin metal sheet is placed in the enclosure 3, ensuring that one side of the thin metal sheet is accurately aligned with the shearing assembly, and the shearing assembly is lowered by the driving member to achieve the cutting of the grooving position of the thin metal sheet.
[0022] It should be noted that: first, the thin metal plates can be placed by stacking multiple plates together in advance and then placing the stacked thin metal plates together in the enclosure 3, or the thin metal plates can be placed in the enclosure 3 one by one, and the specific adjustment can be made according to actual needs. Second, the first sliding rod 5 can be replaced by a screw rod, which is threadedly connected to the first sliding seat 6, and then the screw rod is driven by a motor.
[0023] Furthermore, two symmetrical rails 8 are installed between the first fixed seat 7 and the first sliding seat 6 .
[0024] Furthermore, the shearing assembly includes a limit plate 9, which is located between the first fixed seat 7 and the first sliding seat 6; two symmetrical first slots are provided on the limit plate 9, the first slots are aligned with the rail 8, and the first slots are slidably connected to the rail 8; a plurality of cutters 10 are fixedly connected to the lower side of the limit plate 9, and a plurality of teeth 11 are provided on the cutters 10.
[0025] The above scheme is adopted: when in use, when grooving a thin metal sheet, before this, the thin metal sheet has been located between the two cutters 10, and the edge of the thin metal sheet that needs to be grooved has been aligned with the blade of one of the cutters 10. At this time, the driving member drives the limit plate 9 to descend, and when the limit plate 9 descends, it will move on the rail 8 through the first slot. Through the guiding effect of the rail 8, the cutter 10 will gradually come into contact with the thin metal sheet while descending, completing the grooving process.
[0026] When the grooving is completed, the driving member drives the limit plate 9 to rise. Since the cutter 10 is provided with a latch 11 inside, the latch 11 will extend into the thin metal sheet when the cutter 10 descends, separating the cut waste from the thin metal sheet, and clamping the waste when the cutter 10 rises, and separating from the thin metal sheet together with the waste.
[0027] It should be noted that: first, when placing a thin metal sheet, the thin metal sheet needs to be placed between the two cutters 10, and the edge of one side of the thin metal sheet that needs to be grooved needs to be aligned with the blade of the cutter 10. Second, as the number of cutters 10 changes, the thin metal sheet can be placed side by side between the cutters 10, and the number of cutters 10 can be adjusted according to actual needs. Third, since the shape of the cutter 10 is concave, the concave part is an arc, so when the thin metal sheet is grooved, the shape of the edge is also an arc, which is used for subsequent bending, welding or other processing steps.
[0028] Furthermore, the side walls of the cutter 10 are respectively provided with a first cavity 12 and a second cavity 13; a first airbag 14 and a second airbag 15 are respectively installed in the first cavity 12 and the second cavity 13, and a third airbag 16 is sleeved on one of the rails 8; one side of the third airbag 16 is connected to the first airbag 14 through a first flexible hose 17, and the other side of the third airbag 16 is connected to the second airbag 15 through a second flexible hose 18; the latch teeth 11 are respectively installed on the first airbag 14 and the second airbag 15.
[0029] The above scheme is adopted: when in use, the limit plate 9 is used to clamp the waste material with the clamping teeth 11 during the rising process and separate it from the thin metal sheet. At the same time, the rising of the limit plate 9 will squeeze the third airbag 16 on the clamp rail 8, so that the third airbag 16 gradually changes from an expanded state to a compressed state. In this process, the gas generated during the compression process is respectively transported to the first airbag 14 and the second airbag 15 through the first flexible hose 17 and the second flexible hose 18, so that the first airbag 14 and the second airbag 15 gradually change from a compressed state to an expanded state. The deformation conversion of the first airbag 14 and the second airbag 15, and then the clamping teeth 11 synchronously squeeze the cut thin metal sheet to prevent it from falling due to gravity or other factors after cutting.
[0030] When a new batch of thin metal sheets needs to be grooved, the driving member drives the limit plate 9 to descend. This action stretches the third airbag 16, so that the third airbag 16 is no longer in a compressed state. This stretching process causes the gas in the first airbag 14 and the second airbag 15 to flow back to the third airbag 16, thereby releasing the original clamping force on the thin metal sheet, so that the cut thin metal sheet falls onto the base 1.
[0031] The above scheme has the following effects: First, if the above scheme is not used, when the cut thin metal sheet rises with the cutter 10, during this process, without the clamping of external force, the thin metal sheet will separate from the cutter 10 and fall. After setting up the above scheme, the deformation conversion of the first airbag 14 and the second airbag 15, and then the cut thin metal sheet is synchronously squeezed with the clamping teeth 11 to prevent it from falling due to gravity or other factors after cutting is completed.
[0032] Second, if the above solution is not used, if the thin metal sheet cannot be removed from the cutter 10 in time after cutting, it will hinder continuous processing and reduce production efficiency. When the thin metal sheet in the cutter 10 is to be removed, the thin metal sheet remaining in the cutter 10 is usually removed manually. After using the above solution, the stretching action of the third airbag 16 releases the clamping force on the thin metal sheet, so that the cut sheet can fall smoothly onto the base 1, thereby allowing continuous processing and improving production efficiency.
[0033] It should be noted that: first, a protective layer is provided on the side where the first airbag 14 and the second airbag 15 contact the thin metal sheet to prevent damage to the first airbag 14 and the second airbag 15 when in contact with the thin metal sheet. Second, the backs of the first airbag 14 and the second airbag 15 are respectively connected to the inner walls of the first cavity 12 and the second cavity 13 inside the cutter 10, so the first airbag 14 and the second airbag 15 will expand toward the unrestricted side. Third, the number of rails 8 is the same as the number of cutters 10, and there are two rails 8 in each group, so one of the two rails 8 is provided with a third airbag 16, and is connected to the first airbag 14 and the second airbag 15 through the first flexible hose 17 and the second flexible hose 18. Fourth, a magnet can be provided on the first baffle 4 to suck the thin metal sheet dropped on the base 1 onto the magnet, and then it can be removed manually.
[0034] Furthermore, the upper side of the third airbag 16 is fixedly connected to the first fixing seat 7 , and the lower side of the third airbag 16 is fixedly connected to the limiting plate 9 .
[0035] Furthermore, the driving member includes an electric push rod 19, and the electric push rod 19 is located on the first sliding seat 6. A push rod 20 is installed at the output end of the first sliding seat 6, and the other end of the push rod 20 is fixedly connected to the shearing assembly.
[0036] The above scheme is adopted: when in use, when the position of the limit plate 9 needs to be adjusted, by controlling the telescopic action of the electric push rod 19, its output end will extend or retract accordingly, and this action directly drives the push rod 20 to move synchronously, and then through the connection between the push rod 20 and the limit plate 9, the limit plate 9 is driven to realize the displacement change of rising or falling.
[0037] Furthermore, first circular holes are provided on both sides of the limit plate 9; guide rods 21 are installed in the first circular holes, one end of the guide rod 21 is fixedly connected to the first fixed seat 7, and the other end of the guide rod 21 is fixedly connected to the first sliding seat 6; a first spring 22 is fixedly connected between the limit plate 9 and the first sliding seat 6, and the first spring 22 is sleeved on the guide rod 21.
[0038] The above scheme is adopted: when in use, when the limit plate 9 rises or falls in the vertical direction, the limit plate 9 will move along the direction of the guide rod 21 through the preset first circular hole. At the same time, this movement process will also pull the first spring 22 connected to the limit plate 9 to move synchronously. The cooperation between the limit plate 9 and the guide rod 21 ensures the accuracy and precision of the movement direction and avoids deviation or shaking. Secondly, the synchronous movement of the first spring 22 not only enhances the overall stability of the structure, but also can buffer or offset the impact force that may be generated when the limit plate 9 moves to a certain extent, thereby reducing damage to the limit plate 9.
[0039] Furthermore, a pressing plate 23 is slidably connected to the inner wall of the first sliding seat 6 , and second springs 24 are installed at both ends of the pressing plate 23 , and the other end of the second spring 24 is fixedly connected to the limiting plate 9 .
[0040] The above scheme is adopted: when in use, when the limit plate 9 descends, the elastic action of the second spring 24 pushes the pressure plate 23 to slide on the inner wall of the first sliding seat 6 and gradually approach the thin metal sheet. As the limit plate 9 continues to descend, the compression of the second spring 24 increases, and the pressure applied by the pressure plate 23 to the thin metal sheet also increases, thereby effectively fixing the thin metal sheet, preventing deformation at the cutting groove during the cutting process, ensuring the stability of the shearing process, and improving the shearing accuracy and efficiency.
[0041] It should be noted that: the first sliding seat 6 is also provided with two circular holes aligned with the positions of the second springs 24 , so that the second springs 24 can pass through the circular holes and be connected to the pressing plate 23 and the limiting plate 9 respectively.
[0042] Furthermore, a stop plate 25 is slidably connected inside the enclosure 3 , and two symmetrical third springs 26 are fixedly connected between the stop plate 25 and the enclosure 3 .
[0043] The above scheme is adopted: when in use, the push plate 25 is pushed to be in close contact with one side of the thin metal sheet, and during this process, the third spring 26 moves synchronously with the push plate 25 to ensure that the push plate 25 can firmly press against the thin metal sheet. Due to the elastic effect of the third spring 26, the push plate 25 can maintain a certain buffering force when fixing the thin metal sheet, so that the push plate 25 can adaptively adapt to thin metal sheets of different thicknesses and lengths, thereby achieving a stable fixing effect.
[0044] A thin metal sheet grooving processing method, using the thin metal sheet grooving processing mechanical equipment, comprises the following steps: Step S1, the staff adjusts the sliding position of the first sliding seat 6 on the first sliding rod 5; Step S2, synchronously driving the first fixing seat 7 and the shearing assembly to move to adapt to the specific length of the thin metal sheet that needs to be sheared; Step S3, placing the thin metal sheet in the enclosure 3, ensuring that the grooved side of the thin metal sheet is accurately aligned with the shearing assembly; Step S4, the shearing assembly is lowered by a driving member to cut off the opening of the thin metal sheet.
[0045] Working principle of the present invention: During the grooving process of the thin metal sheet, the operator will adjust the sliding position of the first sliding seat 6 on the first sliding rod 5, and simultaneously push the movement of the first fixed seat 7 and the shearing assembly to adapt to the specific length of the shearing part required for the thin metal sheet, so as to facilitate the grooving process of the edge of the sheet. Then, the thin metal sheet is placed in the enclosure 3 to ensure that the grooved side of the sheet is accurately aligned with the shearing assembly. Through the action of the driving member, the shearing assembly is lowered to complete the cutting of the grooved position of the sheet.
