Description

Technical Field

[0001] The invention relates to the technical field of metal pretreatment, and in particular to a feed pretreatment device and method for metal plate processing. Background Art

[0002] Metal has many advantages such as high strength, high hardness and easy processing and forming. It is widely used in technical fields such as construction, industrial manufacturing, electronics and medical treatment, which greatly promotes the diversity of product types. When using metal as raw material to manufacture products, it is often necessary to forge the metal into metal plates.

[0003] The metal plates used by the processing plant will have surface unevenness, bending, twisting, wavy deformation and other defects as well as pollution such as rust and dust due to uneven cooling shrinkage after rolling and various influences during transportation and stacking. These defects make it impossible to obtain the required cutting accuracy when cutting and marking the metal plates, resulting in deviations in the size of the parts, thus affecting the smooth progress of the subsequent processing procedures. In order to ensure the processing quality, the factory will pre-treat the metal plates before cutting, and the common processes are correction, leveling and rust removal. In the leveling process, the non-cutting processing method of rolling is generally adopted. The plastic deformation of the metal is used at room temperature to flatten the microscopic unevenness of the workpiece surface, thereby achieving the purpose of changing the surface structure, mechanical properties, shape and size. After pre-treatment, the corrosion resistance and fatigue resistance of the metal plate can be improved, and its service life can be extended. At the same time, the surface process manufacturing state of the metal plate can be optimized, which is conducive to the cutting and precision blanking of the CNC cutting machine.

[0004] The structure of the existing metal plate pretreatment device is relatively old and the process method is relatively traditional. Generally, it can only level metal plates of a certain specified thickness and has a limited scope of application. At the same time, due to the deformation of the metal plate, in order to avoid failure or accidents in the rolling process, manual assistance is required to cooperate with the leveling process of the metal plate, and manual grinding of the metal plate using a grinder is also required subsequently, which will not only cause smoke and dust to fly, but also cause unnecessary waste of manual labor. Failures are prone to occur if you are not careful, which reduces the safety of metal plate pretreatment and reduces the efficiency of metal plate pretreatment work. Summary of the invention

DETAILED DESCRIPTION

[0041] 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.

[0042] See also Figures 1 to 5 The present invention provides a technical solution: a feed pretreatment device for metal plate processing, comprising a workbench 1 for guiding metal plates, a bracket assembly supporting a mechanical structure is set up between the two sides of the workbench 1, a cleaning mechanism for cleaning dust on the metal plate is installed between the workbench 1 and the bracket assembly, a roller grinding mechanism for leveling and rust removal of the metal plate is installed above the workbench 1, an adjustment assembly for adjusting the feed thickness of the metal plate is installed between the bracket assembly and the roller grinding mechanism, and an auxiliary pushing mechanism for auxiliary pushing of the metal plate is installed on the bracket assembly and above the roller grinding mechanism;

[0043] The roller grinding mechanism is adjusted up and down through the adjustment component on the above-mentioned bracket assembly, and the metal plate is leveled after being adjusted to an appropriate position according to the thickness of the metal plate to be leveled. It can be used for metal plates of different thicknesses, thereby improving the application range of the feed pretreatment device for metal plate processing. Through the coordinated use of the auxiliary pushing mechanism on the bracket assembly, automatic positioning and auxiliary pushing are performed according to the size of the metal plate, so that metal plates with different deformations can be rolled stably. At the same time, the automatic grinding and cleaning mechanism is used to avoid dust flying, save a lot of manpower, avoid accidents in manual operation, reduce the failure rate, and improve the safety of metal plate pretreatment and the efficiency of metal plate pretreatment.

[0044] In this embodiment, the roller grinding mechanism is a structure used to level the metal plate.

[0045] See also Figure 1 , Figure 2 and Figure 3 The roller grinding mechanism includes two roller support plates 401 for supporting the rotation of the rollers and being adjustable up and down at the same time, upper rollers 402 arranged at equal distances are rotatably connected between the two roller support plates 401 through bearings, and lower rollers 403 are rotatably connected to the bracket assembly and located below the upper rollers 402 in a one-to-one correspondence through bearings, and rolling rollers 404 are fixed to the outer sides of the upper rollers 402 and the lower rollers 403, and grinding rollers 405 are fixed to the outer sides of the second-to-last upper roller 402 and the lower roller 403 near the metal plate pushing direction, and a transmission assembly for driving the rotation is installed between one end of the upper roller 402, and a protective cover 407 for protecting the transmission assembly is clamped on the side of the roller support plate 401 close to the transmission assembly, and a clamping block 408 is clamped between the protective cover 407 and the corresponding roller support plate 401 for removing the protective cover 407;

[0046] It should be noted that a slot for the clamping block 408 is provided on the roller support plate 401. The diameters of the grinding roller 405 and the rolling roller 404 are equal, ensuring that the grinding roller 405 can grind the metal plate.

[0047] In this embodiment, the adjustment component is a structure for adjusting the distance between the upper and lower rolling rollers 404 .

[0048] like Figure 2 , Figure 4 and Figure 5As shown, the adjustment assembly includes two pairs of vertical plates 501 on the bracket assembly and located at the front and rear sides of the two roller support plates 401. The vertical plates 501 are internally connected with threaded blocks 502 for sliding up and down. A connecting block 503 is fixed between the threaded blocks 502 and the corresponding surfaces of the corresponding roller support plates 401. The threaded blocks 502 are internally penetrated and threadedly connected with threaded columns 504. The top of the threaded column 504 rotates stably with the vertical plates 501 through bearings. The top of the threaded column 504 is fixed with a rotating handle 505 for applying force to rotate.

[0049] It can be understood that the height of the vertical plate 501 is greater than the height of the roller support plate 401, ensuring that the roller support plate 401 has space for upward and downward adjustment. At the same time, the heights of the threaded block 502 and the connecting block 503 are equal, ensuring that the upward and downward movement of the threaded block 502 will not be limited by the connecting block 503.

[0050] It should be noted that a T-shaped slot for the threaded block 502 to slide up and down is provided on one side of the vertical plate 501 close to the roller support plate 401, and the threaded block 502 slides in the T-shaped slot. A bearing slot for the bearing to be installed is provided inside the vertical plate 501 and below the T-shaped slot. The bottom end of the threaded column 504 passes through the vertical plate 501 and the threaded block 502 in sequence and extends into the bearing slot to be fixed to the corresponding inner ring of the bearing. In addition, the length of the threaded block 502 is greater than the length of the connecting block 503, so that the threaded block 502 and the connecting block 503 can slide in the T-shaped slot.

[0051] In this embodiment, the auxiliary pushing mechanism is a structure used to assist the metal plate in positioning and pushing.

[0052] See also Figure 1 and Figure 2 The auxiliary pushing mechanism includes two linear motors 601 fixed on the bracket assembly and located above the rolling roller 404, wherein the pushing distance of the linear motor 601 can be set and manufactured according to the length of the pre-treated metal plate, and a linkage rod 602 is fixed on the mover seat of the linear motor 601, and a mounting plate 603 is fixed between the bottom ends of the two linkage rods 602, and two mounting grooves 604 are provided at the bottom of the mounting plate 603, and auxiliary positioning components for driving clamping are installed inside the two mounting grooves 604, and a linkage plate 606 for driving clamping positioning is installed at the bottom of the auxiliary positioning component, and a push plate 607 is fixed on the opposite side of the two linkage plates 606, and a positioning plate 608 is fixed between the push plate 607 and the bottom of the corresponding linkage plate 606.

[0053] It should be noted that the top surface of the positioning plate 608 is located at the same horizontal plane as the top of the bottom rolling roller 404, so as to provide auxiliary support for the metal plate. In addition, a rubber wear-resistant layer is fixed on the opposite side of the two push plates 607. When the pushing length of the metal plate is too long, the two push plates 607 can cooperate with the rubber wear-resistant layer to stably clamp and position the left and right sides of the metal plate, and then assist in pushing the metal plate.

[0054] It should also be noted that the sum of the lengths of the two linkage plates 606 and the push plate 607 is equal to the length of the positioning plate 608 and they are aligned. The width of the linkage plate 606 is greater than the width of the push plate 607, so that the corners of the metal plate can fit between the push plate 607 and the positioning plate 608, ensuring that the rolling and pushing of the metal plate is more stable.

[0055] It is understandable that the lengths of the two push plates 607 and the linkage plate 606 can be set according to the use range of the pre-treated metal plate, so as to ensure that the metal plate can be stably clamped as much as possible while clamping more metal plates of different sizes.

[0056] In this embodiment, the support assembly is a structure used to support the entire pretreatment device.

[0057] See also Figures 1 to 2 and Figure 6 The bracket assembly includes two support plates 201 that are fixed on the left and right sides of the workbench 1 for support. L-shaped support rods 202 are fixed on the opposite sides of the two support plates 201 and the left and right sides of the workbench 1. A support plate 203 is fixed between the top ends of the four L-shaped support rods 202, and a servo controller 204 is fixed on the right side of the L-shaped support rod 202 on the right side.

[0058] It should be further explained that each support plate 201 includes a lifting platform 2012 fixed to the workbench 1, and the lifting platform 2012 can provide a stable support force for the drive motor 2013. The inner top wall of the lifting platform 2012 is fixed with the drive motor 2013, and the inner side of the lifting platform 2012 is fixed with a stabilizing block. The stabilizing block cooperates with the lifting platform 2012 to provide a stable environment for the drive motor 2013. The output shaft of the drive motor 2013 is fixed with a connecting rod 2014 that penetrates the stabilizing block and extends to the outside of the lifting platform 2012. The outer surface of the connecting rod 2014 is fixed with a threaded shaft 2015 that penetrates to the outside of the bottom wall of the lifting platform 2012. The outer surface of the threaded shaft 2015 and the bottom of the lifting platform 2012 are threadedly connected with a connecting sleeve 2016. Due to the threaded connection between the connecting sleeve 2016 and the threaded shaft 2015 Function, cooperate with the fixation of the connecting sleeve 2016, can smoothly achieve the purpose of adjusting the height of the support plate 201, the outer surface of the connecting sleeve 2016 is fixed with a stabilizing seat 2011 flush with the top of the connecting sleeve 2016, the outer surface of the connecting rod 2014 and is located below the threaded shaft 2015 and is fixed with a driving gear 2017, the bottom of the stabilizing block and the rear side of the threaded shaft 2015 are fixed with multiple plane bearings, the plane bearings play a connecting effect, and at the same time ensure the stability of multiple connecting shafts, the bottom of each plane bearing is fixed with a connecting shaft extending into the stabilizing seat 2011, the bottom of each connecting shaft is fixed with a linkage gear, the linkage gear located at the front is meshed with the driving gear 2017, and multiple linkage gears are meshed with each other, and the outer surface of each connecting shaft is threadedly connected with a threaded sleeve fixed to the inner wall of the stabilizing seat 2011.

[0059] It can be known that the active gear 2017 drives multiple linkage gears to rotate, which further drives multiple connecting shafts to rotate, thereby achieving stable height adjustment.

[0060] It is understandable that a limit plate is fixed at the bottom of the linkage rod 2014, and the limit plate is located below the driving gear 2017. The limit plate can provide necessary support force for the driving gear 2017 when the driving gear 2017 moves downward, thereby ensuring the stable operation of the driving gear 2017.

[0061] It should be noted that the four L-shaped support rods 202 are symmetrically distributed, and the two L-shaped support rods 202 located on the workbench 1 are located on the front of the support plate 201, so that the support plate 203 supports more evenly. In addition, the lower roller 403 rotates between the two support plates 201 through the bearing.

[0062] It should also be noted that the two roller support plates 401 are respectively located above the two support plates 201 and have equal thickness. The four vertical plates 501 are fixed on the top of the support plates 201 in a left-right symmetrical manner. The two linear motors 601 are fixed at the bottom of the support plate 203 and are distributed parallel to the rolling rollers 404 in the upper and lower directions to ensure the normal operation of the structure.

[0063] At the same time, the support plate 203 is located above the first rolling roller 404 on the front side and is set up before the metal plate enters the rolling roller 404 for rolling, so that the auxiliary pushing mechanism installed under the support plate 203 can push the metal plate into the rolling roller 404 for leveling.

[0064] In this embodiment, the cleaning mechanism is a structure for cleaning and collecting dust on the metal plate.

[0065] like Figure 1 and Figure 2 As shown, the cleaning mechanism includes an industrial vacuum cleaner 301 located below the workbench 1 and fixed on the side of the support plate 201, a bellows 302 is fixed to the suction port of the industrial vacuum cleaner 301, a dust hood 303 is fixed to the other end of the bellows 302, a dust hole 304 is opened on the top of the workbench 1, the dust hood 303 is located below the dust hole 304 and fixed at the bottom of the workbench 1, and a cleaning component is installed on the rear side of the roller grinding mechanism and above the dust hole 304.

[0066] It should be noted that the dust suction hole 304 and the dust suction cover 303 are both in a trapezoidal funnel shape, which is convenient for guiding dust debris. The dust suction cover 303 completely covers the bottom of the dust suction hole 304 to avoid leakage when absorbing dust debris.

[0067] In addition, the cleaning assembly also includes a first upper roller 402 close to the metal plate pushing direction and a brush roller 3051 fixed to the outside of the corresponding lower roller 403, and the outside of the brush roller 3051 is fixedly connected with evenly distributed bristles 3052.

[0068] It should be noted that the grinding roller 405 and the brush roller 3051 are arranged front to back and are both located above the dust suction hole 304, ensuring that the metal plate is first cleaned of rust and then of dust. The length of the top of the dust suction hole 304 is greater than the length of the grinding roller 405 and the brush roller 3051, and the width of the top of the dust suction hole 304 is greater than the distance between the opposite sides of the grinding roller 405 and the brush roller 3051, ensuring that the dust on the metal plate can effectively fall into the dust suction hole 304.

[0069] In addition, the lengths of the rolling roller 404, the grinding roller 405 and the brush roller 3051 are all equal, ensuring that the metal plate can be effectively pre-treated when passing through these three rollers, and the distance between the upper and lower bristles 3052 is not greater than the distance between the two grinding rollers 405, ensuring that the bristles 3052 can brush away the dust on the metal plate.

[0070] In this embodiment, the transmission assembly is a structure for driving the roller shaft to rotate.

[0071] See also Figure 1 and Figure 3 The transmission assembly includes a rotating motor 4061 for driving the upper roller shaft 402 to rotate, a transmission gear 4062 is fixed to the outer side of the upper roller shaft 402 and located on the side of the roller support plate 401 away from the rolling roller 404, and a transmission chain 4063 is meshed between the outer sides of each adjacent two transmission gears 4062.

[0072] The output shaft of the rotating motor 4061 is fixed to one end of one of the upper roller shafts 402 to ensure that the output shaft of the rotating motor 4061 can be driven, and the protective cover 407 is covered on the outside of the transmission chain 4063 to protect the normal operation of the transmission chain 4063.

[0073] In this embodiment, the auxiliary positioning assembly is a structure used to provide power for clamping and positioning the metal plate.

[0074] See also Figure 1 As shown, the auxiliary positioning assembly also includes a cylinder 6051 fixed in the two mounting grooves 604 , and a slider 6052 is fixed at one end of the piston rod of the cylinder 6051 for horizontal sliding in the corresponding mounting groove 604 .

[0075] It is understandable that the piston rods on the two cylinders 6051 move toward the left and right sides, and the two cylinders 6051 are distributed toward the opposite sides of the piston rods, ensuring that the left and right sides of the metal plate can be provided with clamping and positioning power. The piston rods of the two cylinders 6051 move toward or away from each other at the same time, ensuring that the left and right sides of the metal plate are clamped and released at the same time.

[0076] At the same time, the minimum distance between the opposite sides of the two sliders 6052 is no greater than the length of the rolling roller 404, ensuring that the metal plate entering the rolling roller 404 can be positioned and clamped.

[0077] The present invention also provides a technical solution: a feed pretreatment method for metal plate processing, comprising the following steps:

[0078] 1) Measure the thickness of the metal plate to be processed and need to be pre-treated, rotate the corresponding handle 505, drive the threaded block 502 to move up and down, drive the corresponding roller support plate 401 to move up and down through the connecting block 503, and then drive the rolling roller 404 between the two roller support plates 401 to move up and down for adjustment, and adjust the rolling distance between the two corresponding rolling rollers 404 according to the measured thickness of the pre-treated metal plate;

[0079] 2) Place one side of the pre-treated metal plate between two upper and lower rolling rollers 404 with adjusted distances. According to the length of the pre-treated metal plate, start the linear motor 601 so that the linkage rod 602 drives the linkage plate 606, the push plate 607 and the positioning plate 608 at the bottom of the mounting plate 603 to move to the other side of the pre-treated metal plate and align with it;

[0080] 3) Start the two cylinders 6051 at the same time, and drive the two linkage plates 606 to move closer to each other through the slider 6052, until the two corners of the metal plate are engaged between the corresponding linkage plate 606 and the push plate 607, and the bottom is supported by the positioning plate 608;

[0081] 4) Start the rotating motor 4061 to drive the corresponding upper roller shaft 402 to rotate, and through the transmission chain 4063 meshed between every two adjacent transmission gears 4062, the entire row of equidistantly arranged rolling rollers 404, grinding rollers 405 and brush rollers 3051 can be driven to rotate, and the pretreated metal plate is leveled and pushed backwards through the pressure and friction between the upper and lower rolling rollers 404 and the pretreated metal plate;

[0082] 5) The metal plate 404 pushed backward is rotated and polished when passing through the upper and lower grinding rollers 405, so that rust and dust on the surface of the metal plate no longer adhere to it, and then it is cleaned by the bristles 3052 on the upper and lower rotating brush rollers 3051. At the same time, the industrial vacuum cleaner 301 is started, and the cleaned dust is sucked into the industrial vacuum cleaner 301 through the dust suction hole 304 through the dust suction hood 303 and the bellows 302 and collected.

[0083] Working principle:

[0084] Before use, the servo controller (204) is first used to control the two drive motors (2013) to run synchronously, and the drive motor (2013) drives the connecting rod (2014) to rotate, which further drives the threaded shaft (2015) to rotate. At the same time, the driving gear (2017) transmits power to multiple linkage gears at the rear, causing multiple connecting shafts to rotate simultaneously. Due to the joint action of the connecting sleeve (2016) and the multiple threaded sleeves, the height adjustment of the support plate (201) can be smoothly achieved, thereby achieving the purpose of adjusting the height of the entire device.

[0085] When in use, when adjusting the rolling interval according to the thickness of the pre-treated metal plate, the four rotating handles 505 are rotated respectively to drive the threaded column 504 to rotate in place. Since the threaded block 502 slides in the T-shaped slot and is fixed to the roller support plate 401 through the connecting block 503, the threaded block 502 will move up and down in the vertical plate 501 under the action of the threaded rotation thrust of the inner rotating threaded column 504, thereby driving the roller support plate 401 to move up and down, so that the roller connected to the roller support plate 401 can be adjusted. The pressing roller 404 is adjusted up and down to adjust the rolling distance between the upper and lower rolling rollers 404 according to the thickness of the metal plate, and then one side of the pre-treated metal plate is placed between the two corresponding rolling rollers 404 with adjusted distances. According to the length of the pre-treated metal plate, the linear motor 601 is started to drive the linkage rod 602 to move forward and backward, which can drive the linkage plate 606, the push plate 607 and the positioning plate 608 connected to the bottom of the mounting plate 603 to move to the other side of the pre-treated metal plate and align with it, and at the same time, the two cylinders 60 are started. 51, the two linkage plates 606 are driven by the slider 6052 to move closer until the two corners of the metal plate are engaged between the corresponding linkage plates 606 and the push plates 607 and the bottom is supported by the positioning plate 608 to complete the auxiliary clamping of the other side of the metal plate, and then the rotating motor 4061 is started to drive the corresponding upper roller shaft 402 to rotate, and the transmission chain 4063 meshed between each two adjacent transmission gears 4062 can drive the entire row of equidistantly arranged rolling rollers 404 and grinding rollers 405 The brush roller 3051 rotates, and the pretreated metal plate is pushed backward while being leveled through the pressure, friction and reaction force between the upper and lower rolling rollers 404 and the pretreated metal plate. After the leveling is completed, the upper and lower surfaces of the metal plate are automatically polished and brushed to polish and brush off the rust and dust attached to the surface of the metal plate. At the same time, the industrial vacuum cleaner 301 is started, and the dust and the like brushed off are sucked into the industrial vacuum cleaner 301 under the workbench 1 through the dust suction hole 304, the dust suction hood 303 and the bellows 302 for collection.

[0086] In summary, the feed pretreatment device and method for metal plate processing can adjust the upper roller 402 in the roller grinding mechanism up and down through the adjustment component on the bracket assembly, and can adjust the metal plate to an appropriate position according to the thickness of the metal plate to be leveled before leveling the metal plate, so that it can be used for metal plates of different thicknesses, which greatly improves the scope of application of the feed pretreatment device for metal plate processing and can effectively improve the practicality of the device. Through the use of the auxiliary pushing mechanism on the bracket assembly, the positioning auxiliary pushing can be automatically performed according to the size of the metal plate, so that metal plates with different deformations can be rolled stably without manual assistance. At the same time, with the automatic grinding and cleaning mechanism, it can avoid dust flying, save a lot of manpower, and avoid accidents caused by manual operation, reduce the failure rate, and greatly improve the safety of metal plate pretreatment and the efficiency of metal plate pretreatment, solving the problem of low working efficiency of the existing feed pretreatment device for metal plate processing.

[0087] The electrical components appearing in the article are all electrically connected to the main controller and the power supply. The main controller can be a conventional known device for control such as a computer, and the existing public power connection technology is not described in detail in the article.
