Description

Technical Field

[0002] The sheet metal cutting device for metal product processing, as an indispensable tool in modern manufacturing, is rooted in the continuous progress and innovation of industrial technology. This device is usually called a metal sheet cutting machine. Its core function is to accurately and efficiently cut various metal sheets to meet the customized needs of different industries.

[0003] There are still some inconveniences in the use of traditional cutting devices. For example, when facing metal plates with high hardness or uneven thickness, traditional plate cutting devices often expose problems such as low cutting efficiency, severe blade wear and insufficient cutting accuracy. Due to the high hardness, the shear force demand of the blade increases, resulting in a significant reduction in cutting speed. At the same time, high-hardness plates will cause greater wear on the blade. During the cutting process, both sides of the blade are easily affected by friction inside the plate, resulting in dispersion of the cutting force. Especially when cutting harder metals, it is easy for the blade edge to fail to generate sufficient cutting pressure, thereby affecting the cutting effect. Summary of the invention

DETAILED DESCRIPTION

[0029] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0030] Example 1: Please refer to Figures 1 to 8 , a plate cutting device for metal product processing, comprising:

[0031] A shell body 1, a control panel 2 is arranged on one side surface of the shell body 1, a data processor is arranged inside the control panel 2, a feed conveyor belt 3 and a discharge conveyor belt 4 are arranged inside the shell body 1, a cutting table 16 is also arranged inside the shell body 1, the cutting table 16 is located between the feed conveyor belt 3 and the discharge conveyor belt 4, a liftable lower blade 20 is arranged at the center of the cutting table 16, a cleaning roller 9 is arranged above the discharge conveyor belt 4, a start motor for driving the cleaning roller 9 is arranged on one end surface, two mutually meshing transmission gears 10 are arranged on the other end surface of the cleaning roller 9, a rotating toothed disc 11 is meshed on the upper surface of the transmission gear 10, a rotatable connecting block 13 is arranged on one side surface of the rotating toothed disc 11, a rotatable connecting rod 12 is arranged on one side surface of the connecting block 13, a rotatable lifting rod 14 is arranged at one end of the connecting rod 12, an upper blade 48 is arranged below the lifting rod 14, a fixing bar 15 is fixedly installed on the inner side surface of the shell body 1, and the lifting rod 14 passes through the center of the fixing bar 15;

[0032] When performing the cutting work, the staff first inputs the cutting parameters through the control panel 2 on one side of the shell 1. The data processor inside the control panel 2 receives and processes the input data, and then sends instructions to the entire cutting system. Subsequently, the staff places the metal product sheet to be cut on the feed conveyor 3. As the conveyor belt is started, the sheet moves along the set path to the cutting table 16. When the sheet arrives at the cutting table 16, the data processor will control the motor to drive the liftable lower blade 20 to the appropriate cutting height according to the preset cutting parameters to achieve precise cutting. When the upper and lower blades are ready, the data processor triggers the cutting action, the lower blade 20 remains stationary, and the upper blade 48 descends and contacts the sheet to complete the cutting. After the cutting is completed, the discharge conveyor 4 starts to transport the cut sheet from the cutting table 16 to the subsequent process or collection area.

[0033] The above process is the basic process of metal sheet cutting at present.

[0034] However, in the actual process of cutting plates, due to the different hardness and thickness of different metal plates, when cutting plates with higher hardness, the shear force required in the cutting process will also increase, which will increase the load on the motor of the cutting machine and reduce the cutting speed, thereby reducing the cutting efficiency. Plates with higher hardness will also cause greater wear on the blades during the cutting process, shortening the service life of the blades. In the process of cutting metal plates, after the upper and lower blades cut into the metal plates, the two sides of the blades are rubbed by the inside of the plate, so that the force of the blades when cutting into the metal plates is dispersed. When cutting some harder metals, it is easy for the blade edge to fail to generate the pressure required for cutting the metal plate due to the dispersed force, resulting in poor cutting effect and reduced cutting speed.

[0035] In addition, when adjusting the size of the board, the existing cutting machines usually need to manually adjust the tool position or change the cutting program. The process is cumbersome and time-consuming. Manual adjustment may lead to reduced cutting accuracy, especially when multiple boards of different sizes need to be cut in a short period of time. The accuracy problem is particularly prominent.

[0036] Therefore, based on the above problem, we first designed a plate twisting mechanism, which includes a force-applying component and a swinging component. The force-applying component includes: a connecting platform 52, which is sleeved on the surfaces of the two lifting rods 14 and is located below the fixing bar 15. A plurality of reset springs 51 are arranged below the connecting platform 52. The bottom surface of the reset spring 51 is connected to the upper surface of the upper blade 48. A knife seat is fixedly installed on the bottom surface of the lifting rod 14. The upper blade 48 is located below the knife seat and can be lifted and lowered. A force-bearing sheet 49 is arranged on both sides of the upper surface of the upper blade 48. A pressure frame is arranged on the upper surface of the force-bearing sheet 49. 50, a sliding base column 55 is provided on one side of the bottom surface of the pressure frame 50, a positioning platform 56 is provided at the bottom of the sliding base column 55, and a plurality of electric push rods 57 are also provided on the upper surface of the positioning platform 56, and the output shaft end of the electric push rod 57 is connected to the bottom surface of the lower blade 20, and a plurality of bottom springs 58 are provided on the bottom surface of the positioning platform 56, and the bottom spring 58 is connected to the inner bottom surface of the cutting table 16, and a lifting sliding block 54 is fixedly installed on the middle section of the sliding base column 55, and a telescopic motor 53 is also fixedly installed on the inner side surface of the housing 1, and the output shaft end of the telescopic motor 53 is connected to the upper surface of the lifting sliding block 54;

[0037] During the cutting process, after the upper blade 48 and the lower blade 20 have cut marks on the upper and lower surfaces of the plate, the swing component is started to drive the cutting section to swing up and down, and the connection between the cutting section and the raw material section is twisted to reduce the connection effect between the two sections of material. Then, the upper blade 48 and the lower blade 20 are given additional driving force by the force attachment component. When the swing component is in operation, the two blades have a stronger cutting effect on the connection, so that the two blades have a faster penetration speed when cutting the plate, thereby achieving the effect of improving the cutting effect. During use, the force attachment component receives the signal generated when the two rotating branches 38 of the swing component are triggered through the data processor inside the control panel 2, and drives the telescopic motor 53 to retract / extend according to the generated signal. Taking the upper blade as an example, the pressure sensor 40 above the rotating branch 38 on the side of the upper blade of the meshing toothed disc 32 corresponding to the upper blade senses the pressure and transmits the signal to the data processor. At this time, as the swing component moves from One side of the cutting section drives it to twist upward, and the blade edge on the upper side of the connection between the two sections of material expands due to the force. At this time, the data processor drives the telescopic motor 53 to extend through the signal, drives the sliding base column 55 to descend through the lifting sliding block 54, and applies pressure to the force-bearing sheet 49 through the pressure frame 50. Subsequently, the return spring 51 between the upper blade 48 and the connecting platform 52 is stretched and deformed, so that the upper blade 48 produces a downward impact force. With the effect of the swing component, the two sides of the upper blade 48 lose the friction effect with the inside of the plate, and with this impact force, the upper blade 48 can produce a stronger penetration effect on the connection between the two sections of the plate at this time, so that the connection is cut faster. At this time, the swing component drives the cutting section to move in the opposite direction. At this time, the telescopic motor 53 is contracted, driving the lower blade 20 below to perform an upward impact effect. Through the continuous impact effect on both sides, the metal plate with higher hardness can be broken faster.

[0038] The swing assembly includes: a slide platform 21, the slide platform 21 is fixedly mounted on the inner side surface of the housing 1, a slidable slide trolley 30 is arranged on the upper surface of the slide platform 21, a meshing rack 34 is arranged on the upper surface of the slide trolley 30, a meshing toothed disc 32 is meshed on the upper surface of the meshing rack 34, two triggering top plates 33 are arranged on one side surface of the meshing toothed disc 32, a rotating sleeve 31 is arranged on one side surface of the meshing toothed disc 32, a clamping strip 22 is arranged on one side surface of the rotating sleeve 31, and a clamping strip 22 is arranged on one side of the clamping strip 22. A pressure-touch switch 23 is provided on the surface, a lifting and lowering limiting clamping strip 24 is also provided on one side surface of the clamping strip 22, a top mounting frame 26 is fixedly installed on the upper surface of the clamping strip 22, a driving motor 27 is provided at the center of the top mounting frame 26, and the output shaft of the driving motor 27 is connected to the upper surface of the limiting clamping strip 24, a non-slip sheet 28 matching with the limiting clamping strip 24 is also provided on one side surface of the clamping strip 22, and a connecting sheet 25 is also provided on one side surface of the clamping strip 22. A shaft body is provided at the joint, a fixed inner rod 44 is provided inside the rotating sleeve 31, a sliding plate 29 is provided on one side surface of the fixed inner rod 44, a sliding groove is provided inside the housing 1 for facilitating the sliding of the sliding plate 29, a brake motor 37 is fixedly installed on one side surface of the sliding plate 29, a connecting rod 35 is provided at the end of the output shaft of the brake motor 37, one side surface of the connecting rod 35 is connected to one side surface of the meshing rack 34, and two side surfaces of the sliding plate 29 are also provided with two trigger top sheets 33 respectively. The sliding plate 29 is provided with an internal motor for driving the rotating branch 38 to rotate, and a pressure sensor 40 is provided at the end of the rotating branch 38. There is an electrical connection between the pressure sensor 40 and the control panel 2. A force arc plate 39 that matches the trigger top sheet 33 is provided at the end of the pressure sensor 40. A surface limiting strip 41 is also provided on one side surface of the rotating branch 38, and an auxiliary limiting strip 36 that matches the surface limiting strip 41 is also fixedly installed on the side surface of the sliding plate 29;

[0039] The swing assembly is used to drive the cutting section to twist when in use, so as to make the connection deform and break more quickly. When in use, when the metal sheet is transmitted through the feed conveyor belt 3, after one end of the sheet contacts the clamping bar 22, one end of the sheet triggers the pressure touch switch 23 and transmits the signal to the data processor. Then, the data processor controls the drive motor 27 to extend, and the limiting clamping bar 24 is lowered to cooperate with the anti-slip sheet 28 to clamp one end of the sheet. Then, after the upper blade 48 and the lower blade 20 cut into the interior of the metal sheet, the brake motor 37 is driven by the signal to reciprocate and extend, driving the meshing rack 34 to reciprocate. During the rotation process, the clamping bar 22 clamps one end of the cutting section and swings up and down, so that the gap between the cutting section and the raw material section is enlarged. As the cutting work proceeds, the extension and retraction amplitude of the brake motor 37 gradually increases. Strong, so that the swing amplitude of the clamping bar 22 is gradually enhanced. During the rotation of the meshing toothed disc 32, the trigger top plates 33 on both sides of the meshing toothed disc 32 are respectively in contact with the force-bearing arc plates 39 at the ends of the rotating branches 38 on both sides of the slide plate 29. After the force-bearing arc plates 39 are stressed, they compress the pressure sensor 40, and send a signal to the data processor through the pressure sensor 40, so that the data processor controls the telescopic frequency of the telescopic motor 53. After the cutting is completed, the two rotating branches 38 are driven to rotate by the internal motor inside the slide plate 29, so that the meshing toothed disc 32 will not be blocked by the two rotating branches 38 when rotating. After the clamping bar 22 rotates downward, and the data processor sends a signal to the drive motor 27 to contract, so that the cut section loses the clamping effect, the cut section falls downward to the top of the discharge conveyor belt 4, and then is transmitted out of the equipment.

[0040] The plate twisting mechanism also includes an auxiliary component, which includes: a pressure tester 7, which is arranged on the inner side surface of the shell 1, a movable block 6 is arranged at the end of the output shaft of the pressure tester 7, and a test roller 5 is arranged on one side surface of the movable block 6. A connecting spring 8 is arranged between the upper surface of the movable block 6 and the inner side surface of the shell 1. The auxiliary component also includes a pressing plate 17, which is located above the cutting table 16. Two electric telescopic rods for driving it to rise and fall are arranged on the upper surface of the pressing plate 17, and one side surface of the electric telescopic rod is connected to the inner side surface of the shell 1. The auxiliary component also includes a bearing platform 18, which is fixedly mounted on the cutting table 16. A plurality of movable support bars 19 are arranged on one side surface of the cutting table 16 and the upper surface of the bearing platform 18, a second sleeve 43 is arranged on one side surface of the movable support bar 19, a second toothed disc 45 is arranged at one end of the second sleeve 43, a fixed inner rod 44 is also arranged inside the second sleeve 43, a fixed disc 42 is arranged on one side surface of the fixed inner rod 44, the fixed disc 42 is fixedly mounted on the inner side surface of the housing 1, a small motor 47 is arranged on one side surface of the fixed disc 42, a connecting rod 35 is also arranged at the end of the output shaft of the small motor 47, a second rack 46 is arranged on one side surface of the connecting rod 35, and the upper surface of the second rack 46 is meshed with the second toothed disc 45;

[0041] The auxiliary component is used to assist the cutting work of the force-attaching component and the swing component, wherein the test roller 5 can play a role when the metal sheet is transmitted along the feed conveyor belt 3. When the sheet passes under the test roller 5, the test roller 5 is pushed upward. At this time, the pressure tester 7 above the movable block 6 is compressed, and then the data is transmitted to the control panel 2, and the thickness of the sheet is judged by the data processor therein, so as to judge how far the upper blade 48 starts to cut into the inside of the metal sheet after descending. Since the blade height of the lower blade 20 is flush with the upper surface of the cutting table 16, when the metal sheet reaches the cutting position, the electric push rod 57 drives the lower blade 20 to rise, which generates pressure on the bottom surface of the metal sheet. Therefore, when the upper blade 48 descends to the specified position according to the sheet thickness data obtained by the pressure tester 7, that is, the blades of the upper blade 48 and the lower blade 20 are in contact with the surface of the metal sheet, the blades on both sides are in contact with the surface of the metal sheet. The sheets apply force at the same time to produce a shearing effect. The pressing plate 17 of the auxiliary component is used to fix the raw material segment during the cutting process to prevent the raw material segment from moving when the swing component drives the cutting segment to twist, thereby reducing the expansion effect of the upper and lower knife marks. The role of the support platform 18 is to provide support force for the metal plate cutting process. During the cutting process, the movable support bar 19 maintains a planar state to provide bottom support for the metal plate. After the cutting is completed, the small motor 47 is started by a signal drive, and the second sleeve 43 is driven to rotate on the surface of the fixed inner rod 44 through the meshing effect of the second rack 46 and the second gear disc 45, and then the movable support bar 19 is rotated, so as to be collected into the interior of the support platform 18, so that the upper surface of the support platform 18 has a downward slope, and cooperates with the swing component to cancel the clamping effect, so that the cutting segment quickly slides above the discharge conveyor belt 4, and then is transported out of the equipment.

[0042] At the same time, based on the above problems, we also designed an adjustment component, which includes: a numerical mark 59, which is arranged on the inner side surface of the shell 1, an adjustment slide is provided on the inner side surface of the shell 1, a rotatable threaded rod 60 is provided inside the adjustment slide, a meshing slider 61 is meshed on the surface of the threaded rod 60, a rotating motor 62 is provided inside the adjustment slide, an output end of the rotating motor 62 is connected to one side surface of the threaded rod 60, a connecting branch 63 is provided on one side surface of the meshing slider 61, and one end of the connecting branch 63 is connected to one side surface of the connecting piece 25;

[0043] The adjustment component displays the cutting size of the current cutting section through the numerical mark 59. The staff can drive the rotating motor 62 to rotate the threaded rod 60 through the signal as needed. The thread on the surface of the threaded rod 60 engages with the meshing slider 61, driving the meshing slider 61 to move in the adjustment slide. The connecting branch 63 converts the movement of the meshing slider 61 into the displacement of the clamping bar 22, thereby realizing precise adjustment of the cutting size of the plate. The slide plate 29 can slide on the inner side surface of the shell 1 following the movement of the clamping bar 22, and the slide trolley 30 under the meshing rack 34 also slides on the upper surface of the slide platform 21, thereby providing support force for the swing component.

[0044] The working principle of the present invention is:

[0045] When cutting, the worker first inputs the cutting parameters through the control panel 2 on one side of the housing 1. The data processor inside the control panel 2 receives and processes the input data, and then sends instructions to the entire cutting system. The adjustment component displays the cutting size of the current cutting section through the numerical mark 59. The worker can drive the rotating motor 62 to rotate the threaded rod 60 through the signal as needed. The threads on the surface of the threaded rod 60 mesh with the meshing slider 61, driving the meshing slider 61 to move in the adjustment slideway. The connecting branch 63 converts the movement of the meshing slider 61 into the displacement of the clamping bar 22, thereby realizing the precise adjustment of the cutting size of the plate.

[0046] Subsequently, the metal product sheet to be cut is placed on the feed conveyor belt 3 by the staff. As the conveyor belt is started, the sheet moves along the set path toward the cutting table 16. When the sheet reaches the cutting table 16, the data processor drives the lower blade 20 which can be raised and lowered to an appropriate cutting height by controlling the motor according to the preset cutting parameters, so as to achieve precise cutting.

[0047] During the cutting process, after the upper blade 48 and the lower blade 20 have cut marks on the upper and lower surfaces of the plate, the swing component is started to drive the cutting section to swing up and down, and the connection between the cutting section and the raw material section is twisted to reduce the connection effect between the two sections of material. Then, the upper blade 48 and the lower blade 20 are given additional driving force by the force attachment component. When the swing component is in operation, the two blades have a stronger cutting effect on the connection, so that the two blades have a faster penetration speed when cutting the plate, thereby achieving the effect of improving the cutting effect. During the use of the force attachment component, the two rotating branches 38 of the swing component are triggered by receiving the data processor inside the control panel 2. The signal generated when the upper blade 48 is cut is driven by the telescopic motor 53 to retract / extend according to the generated signal, so that the upper blade 48 generates a downward impact force, and with the effect of the swing component, the two sides of the upper blade 48 lose the friction effect with the inside of the plate, and with this impact force, the upper blade 48 can produce a stronger penetration effect on the connection between the two sections of the plate at this time, so that the connection is cut faster, and at this time, the swing component drives the cutting section to move in the opposite direction, and at this time, the telescopic motor 53 is retracted to drive the lower blade 20 below to perform an upward impact effect, and through the continuous impact effect on both sides, the metal plate with higher hardness can be broken faster;

[0048] The swing assembly is used to drive the cutting section to twist when in use, so as to make the connection deform and break more quickly. When in use, when the metal sheet is transmitted through the feed conveyor belt 3, after one end of the sheet contacts the clamping bar 22, one end of the sheet triggers the pressure touch switch 23 and transmits the signal to the data processor. Then, the data processor controls the drive motor 27 to extend, and the limiting clamping bar 24 is lowered to cooperate with the anti-slip sheet 28 to clamp one end of the sheet. Then, after the upper blade 48 and the lower blade 20 cut into the interior of the metal sheet, the brake motor 37 is driven by the signal to reciprocate and extend, driving the meshing rack 34 to reciprocate. During the rotation process, the clamping bar 22 clamps one end of the cutting section and swings up and down, so that the gap between the cutting section and the raw material section is enlarged. As the cutting work proceeds, the extension and retraction amplitude of the brake motor 37 gradually increases. Strong, so that the swing amplitude of the clamping bar 22 is gradually enhanced. During the rotation of the meshing toothed disc 32, the trigger top plates 33 on both sides of the meshing toothed disc 32 are respectively in contact with the force-bearing arc plates 39 at the ends of the rotating branches 38 on both sides of the slide plate 29. After the force-bearing arc plates 39 are stressed, they compress the pressure sensor 40, and send a signal to the data processor through the pressure sensor 40, so that the data processor controls the telescopic frequency of the telescopic motor 53. After the cutting is completed, the two rotating branches 38 are driven to rotate by the internal motor inside the slide plate 29, so that the meshing toothed disc 32 will not be blocked by the two rotating branches 38 when rotating. After the clamping bar 22 rotates downward, and the data processor sends a signal to the drive motor 27 to contract, so that the cut section loses the clamping effect, the cut section falls downward to the top of the discharge conveyor belt 4, and then is transmitted out of the equipment.
