Description

[0001] This application is a divisional application of the invention patent application filed on April 3, 2022, with application number 202210347318.1 and invention title "A metal sheet grooving and cutting process and an integrated grooving and cutting machine". Technical Field

[0002] This invention relates to the field of metal sheet grooving and cutting technology, and particularly to a composite machine for metal sheet grooving and laser cutting. Background Technology

[0003] The emerging mid-to-high-end building materials and decoration industry, both domestically and internationally, has placed higher demands on the required metal decorative materials. Specifically, it requires that the radius of curvature of the edges of bent sheet metal workpieces be as small as possible, and that the surface of the sheet metal workpieces be free of refraction. It also demands that the cross-sectional shape of the bent sheet metal workpieces be more complex, better reflecting the designer's trendy design style. Currently, traditional forced bending methods, free bending methods, and even three-point bending processes are no longer capable of bending sheet metal workpieces with small curvatures. In other words, simply using a bending machine to bend sheet metal workpieces can no longer meet the designer's requirements and achieve the desired level of quality and decorative effect for mid-to-high-end decorations.

[0004] Currently, in the metal sheet grooving industry, the typical process involves grooving the metal sheet and then transferring it to another machine for cutting or trimming, separating large sheets into individual pieces. The shortcomings of this existing process are: 1. It requires multiple machines, increasing the cost of grooving and cutting, and the changeover between machines also lengthens the process time, thus reducing efficiency; 2. Loading, positioning, grooving, and shearing require at least eight operators, resulting in high labor costs and significant safety hazards. Summary of the Invention

[0005] This invention provides a composite machine for grooving and laser cutting metal sheets, as well as the grooving and cutting processes. This composite machine integrates the grooving and cutting processes, which previously required separate equipment, into a single machine. This eliminates the need to switch equipment between the grooving and cutting processes, allowing for grooving and cutting (shearing) of entire metal sheets, saving time and labor, and reducing production costs. Furthermore, the composite machine features a laser cutting clearance structure in the center of the worktable. This allows metal debris generated during laser cutting to fall into or from the clearance structure into a predetermined receiving cavity, preventing the debris from being melted and adhered to the cut edge of the metal sheet again. It also prevents metal debris from flying and injuring operators, thus improving the quality of metal sheet grooving and laser cutting and enhancing operator safety. To address the above problems, the technical solution provided by this invention is as follows:

[0006] This invention discloses a composite machine for grooving and laser cutting of metal sheets, comprising: a frame, a table panel, hydraulic pressure plates, a rear feeding device, a grooving and laser cutting device, and a control system.

[0015] The original application of this invention contains the following:

[0016] A metal sheet grooving and cutting process involves grooving a whole sheet of metal into V-shaped, U-shaped, or other shaped grooves, and then cutting the large sheet into narrow strips of individual metal sheets. The process includes the following steps:

[0017] Step 1: Position the metal sheet to be processed at the grooving station of the grooving and cutting machine. Start the planer of the grooving and cutting machine to groove the metal sheet according to the preset program. The planer of the grooving and cutting machine performs at least one grooving operation on the same groove to make the shape and size of the groove on the metal sheet meet the predetermined requirements. Depending on the design requirements of the shape and depth of the groove, the same groove can be grooved once, twice or more.

[0018] Step 2: If multiple grooves need to be cut into the metal sheet, repeat the operation in Step 1; as needed, process two or more grooves into the entire metal sheet.

[0019] Step 3: After completing part or all of the grooving of the metal sheet, turn off the planer blade of the grooving and cutting machine, and start the laser cutting device or shearing device of the grooving and cutting machine to laser cut or shear the metal sheet into individual metal sheets. The laser cutting device or shearing device and the planer blade device are mounted simultaneously on the frame of the grooving and cutting machine.

[0020] The existing metal sheet grooving and cutting process is as follows: First, the metal sheet to be processed is loaded onto the grooving machine, and the entire metal sheet is fixed in the predetermined work position by a hydraulic pressure plate. The processing starting point of the planer is adjusted, and the planer is started to cut and groove the metal sheet, processing preset V-shaped grooves or U-shaped grooves, etc., on the metal sheet. Then, after all the preset grooves on the entire metal sheet are processed, the entire metal sheet is transferred to a shearing device, where it is sheared to form narrow strips of single metal sheet. The significant drawback of this method is that it requires two machines and involves a large-scale change of site / position, doubling the cost of grooving and cutting, and manual transfer poses more safety risks. Another existing method is to process all the pre-set grooves on the whole metal sheet, and then make grooves at the pre-set shearing points. The grooves here should be as deep as possible so that they can be broken by hand. Then the whole metal sheet is transferred to another platform and manually broken (bent) into narrow strips of single metal sheets. The significant drawback of this method is that the broken parts are not completely planed, resulting in uneven fracture marks and burrs.

[0021] The metal sheet grooving and cutting process of this invention integrates grooving and cutting onto a single machine, eliminating the need to transfer the metal sheet between processes. Cutting can be performed simply by adjusting the cutting position of the metal sheet. This reduces factory and equipment costs, as well as labor costs, by 70%-80%. Furthermore, the elimination of metal sheet transfer between the two processes improves processing efficiency and automation. Additionally, the removal of the transfer process reduces safety hazards. Although it integrates two traditional processes, no manufacturer or forming equipment in the field has implemented this method in existing metal sheet grooving and cutting processes. This invention solves a long-standing technical problem in metal sheet processing, achieving unexpected technical benefits: high speed and efficiency, low safety risks, and better grooving and cutting quality.

[0022] Furthermore, in step one, if the planer blades of the grooving cutter perform two or more grooving / planing operations on the same workpiece groove, the planer blades also perform grooving / planing operations during the return stroke of the planer blade mounting frame. That is, two sets of planer blades are mounted opposite each other on the planer blade mounting frame of the grooving cutter. One set of planer blades is fixed to perform grooving operations from right to left, and the other set is fixed to perform grooving operations from left to right. The two sets of planer blades alternately cut and grooved in the outward and return directions, thus significantly improving processing efficiency while saving energy during the return stroke of the planer blade mounting frame.

[0023] Further, in step three, after processing the predetermined number of grooves on the single metal sheet, the laser cutting device or shearing device of the grooving and cutting machine is activated to cut the single metal sheet off, and then the next round of grooving and cutting is performed. That is, if the final single metal sheet requires two, three, or more V-grooves, after processing two, three, or more V-grooves, the single metal sheet is sheared or laser-cut off according to the predetermined size, pushed out from the rear end of the equipment, and then the processing of V-grooves on the next single metal sheet continues. All the single metal sheets are stacked and transported together at the rear end of the equipment.

[0024] Furthermore, in step three, after all the grooves on the metal sheet are planed, the laser cutting device or shearing device of the grooving and cutting machine is started to cut it into individual metal sheets one by one. That is, if 10 V-grooves need to be processed on the whole metal sheet and it needs to be cut into 5 individual metal sheets, then all 10 V-grooves are planed first before cutting and splitting into individual metal sheets. In this way, for grooving and cutting of the whole metal sheet, it is not necessary to switch between the planer and the cutting device in the middle, which can further improve work efficiency.

[0025] Furthermore, in step one, the grooving and cutting machine can simultaneously perform two or more grooving operations on the metal sheet in the horizontal direction. That is, if two or more grooves need to be made on a single metal sheet, the two or more grooves can be completed in one go. In other words, the grooving and cutting machine has two or more rows of planing blades installed in the horizontal direction, and simultaneously cuts two or more V-shaped grooves on the metal sheet.

[0026] Furthermore, the longitudinal grooving centerline of the planer blade of the grooving cutting machine does not coincide with the longitudinal cutting centerline of the laser cutting head. When grooving, the planer blade needs to be directly facing the solid worktable surface. However, the laser cutting head requires a clearance structure for cutting because the planer blade does not cut through the metal sheet during grooving; that is, there is a certain distance between the planer blade and the worktable surface. The planer blade will not scratch the worktable surface, and the worktable surface is needed to absorb the impact force of the planer blade; otherwise, the metal sheet will dent at the grooving location. Laser cutting, on the other hand, requires cutting the metal sheet. A dedicated clearance structure is provided on the worktable surface. If the laser cutting is directed at the worktable surface that the planer blade is facing, instead of the clearance structure, the laser will melt and damage the worktable surface. Therefore, the longitudinal movement direction of the planer blade and the longitudinal movement direction of the laser cutting head do not overlap; that is, the planer blade and the laser cutting head need to be offset by a certain position in the horizontal direction. Here, "longitudinal" refers to the direction of movement of the planer blade when grooving, and "horizontal" refers to the direction perpendicular to "longitudinal" on the horizontal plane.

[0027] The present invention provides an integrated metal sheet grooving and cutting machine for realizing the above-mentioned metal sheet grooving and cutting processes.

[0028] Specifically, the integrated metal sheet grooving and cutting machine includes: a frame, front and rear support frames, a table panel, hydraulic pressure plates, a rear feeding device, a grooving and laser cutting device, and a control system. The front and rear support frames include a front support frame and a rear support frame, which are respectively fixedly installed at the front and rear of the frame. The table panel is fixedly installed on the worktable of the frame, and a laser cutting clearance structure is provided in the middle of the table panel. Multiple hydraulic pressure plates are arranged side by side inside the frame, and the multiple hydraulic pressure plates are located above the table panel. During operation, the hydraulic pressure plates hold the metal sheet to be processed. The hydraulic plates are pressed against the table panel, and multiple hydraulic plates are connected to the hydraulic control of the hydraulic station. The rear feeding device is fixedly installed at the rear of the frame, and includes a rear feeding hydraulic clamp that is slidably mounted on the rear feeding device. The grooving and laser cutting device is slidably mounted on the frame and located directly above the table panel. The grooving and laser cutting device is either a single-head or double-head grooving and laser cutting device. The control system is connected to the hydraulic plates, the rear feeding device, and the grooving and laser cutting device via circuit control. The front and rear support frames are used to support the metal sheet before and after grooving and cutting. The hydraulic plates are used to press the metal sheet firmly against the table panel when the planer cuts grooving, so that the metal sheet is fixed while the planer cuts on the metal sheet to groove.

[0029] The single-head grooving and laser cutting device includes a tool holder plate, a servo motor base plate, an X-axis device, a W-axis device, a C-axis device, a tool holder device, a chip scraper device, and a mounting sliding guide groove. The servo motor base plate is vertically fixed on the tool holder plate. The X-axis device is located on the tool holder plate above the servo motor base plate. The W-axis device and the C-axis device are located on the servo motor base plate and the tool holder plate below the servo motor base plate, respectively. The chip scraper device is located on the W-axis device, and the tool holder device is located on the chip scraper device. The mounting sliding guide groove is located on the back of the tool holder plate and is adapted to the X-axis linear guide rail located on the frame. The single-head grooving and laser cutting device is slidably mounted on the frame via the mounting sliding guide groove and the X-axis linear guide rail.

[0030] The X-axis device includes an X-axis servo motor, an X-axis reducer, an X-axis drive shaft, and an X-axis drive gear. The X-axis servo motor and the X-axis reducer are mounted on the front of the tool holder plate. The X-axis drive shaft passes through the tool holder plate and connects the X-axis reducer and the X-axis drive gear. The X-axis drive gear is adapted to an X-axis rack mounted on the frame. The X-axis drive gear and the X-axis rack cooperate to drive the single-head grooving and laser cutting device to slide along the X-axis.

[0031] The W-axis device includes a W-axis servo motor, a W-axis synchronous pulley, a W-axis ball screw, and a W-axis slider. The W-axis servo motor and the W-axis synchronous pulley are mounted on the servo motor base plate. The W-axis slider is disposed on the tool holder plate below the servo motor base plate. The W-axis ball screw connects the W-axis synchronous pulley and the W-axis slider. The chip scraping device is disposed on the W-axis slider.

[0032] The chip scraping device includes a chip scraping cylinder, a chip scraping connecting rod, a chip scraping connecting plate, a chip scraping guide rod, and a chip scraping plate. The chip scraping cylinder is mounted on the W-axis slider. The chip scraping connecting rod connects the chip scraping cylinder to the chip scraping connecting plate. The chip scraping plate is mounted below the chip scraping connecting plate via two chip scraping guide rods.

[0033] The tool holder device includes an upper tool holder, a tool pressure plate, and a high-speed steel planer blade. The upper tool holder is mounted on the W-axis slider via two chip scraper guide rods, and the high-speed steel planer blade is mounted on the upper tool holder via the tool pressure plate. The tool holder device is also equipped with a table cleaning brush device, which includes a brush fixing bracket and a cleaning brush. The brush fixing bracket is fixedly mounted on the upper tool holder.

[0034] The C-axis device includes a C-axis servo motor, a C-axis synchronous pulley, a C-axis ball screw, and a C-axis slider. The C-axis servo motor and the C-axis synchronous pulley are mounted on the servo motor base plate. The C-axis slider is located on the tool holder plate below the servo motor base plate. The C-axis ball screw connects the C-axis synchronous pulley and the C-axis slider. A laser head is mounted on the C-axis slider. Thus, the single-head grooving and laser cutting device is mounted on the front of the grooving machine. Movement in the X-axis direction is achieved through the X-axis servo motor. The C-axis and W-axis servo motors drive the C-axis and W-axis synchronous pulleys, which in turn drive the C-axis and W-axis ball screws. This causes the V-shaped slider to slide stably and rapidly between the left and right V-shaped guide bars, thereby driving the tool holder device and laser head to groove and cut on the workpiece. The positioning is precise, the grooving depth error is small, and combined with laser cutting, it ensures the dimensional accuracy of the workpiece grooving, further improving the efficiency of grooving.

[0035] The dual-head grooving and laser cutting device includes the single-head grooving and laser cutting device and a Z-axis device, which is symmetrically arranged with the W-axis device. The Z-axis device includes a Z-axis servo motor, a Z-axis synchronous pulley, a Z-axis ball screw, and a Z-axis slider. The Z-axis slider is equipped with a chip scraper, a tool holder, and a table cleaning brush. Thus, the dual-head grooving and laser cutting device is mounted on the front of the grooving machine. Movement in the X-axis direction is achieved via the X-axis servo motor. The C-axis, W-axis, and Z-axis servo motors drive the synchronous pulleys, which in turn drive the ball screw, causing the V-shaped slider to slide stably and rapidly between the left, middle, and right V-shaped guide bars. This drives the tool holder and laser head to groove and cut on the workpiece, resulting in precise positioning, minimal grooving depth error, and, combined with laser cutting, ensuring the dimensional accuracy of the workpiece grooving, further improving grooving efficiency.

[0036] When grooving workpieces, grooving machines require high precision. The Z-axis and W-axis devices of the grooving machine are used to control the grooving depth. The system sends a signal to the Z-axis or W-axis servo motor, which starts rotating. Under the transmission of the synchronous pulley and synchronous belt, the lead screw moves up and down, thereby driving the tool holder and the cutter to move up and down, thus controlling the grooving depth. The C-axis device is based on the height set by the workpiece surface above the cutting head nozzle. When cutting is required, the system sends a signal to the C-axis servo motor, which starts rotating. Under the transmission of the synchronous pulley and synchronous belt, the lead screw moves up and down, thereby driving the slider to move up and down, thus controlling the set height.

[0037] The beneficial effects of the metal sheet grooving and cutting process provided by this invention are:

[0038] Grooving and cutting are completed on the same machine without the need to switch equipment in between. On the one hand, this reduces equipment and factory costs and labor costs. On the other hand, it improves processing efficiency and automation. Furthermore, it eliminates the need for transportation, thus reducing safety hazards. Attached Figure Description

[0061] The specific embodiments of the original application of this invention are as follows:

[0062] Please refer to the attached document. Figure 1 This embodiment describes a metal sheet grooving and cutting process, which includes the following steps:

[0063] Step 1: Position the metal sheet to be processed at the grooving station of the grooving and cutting machine, and start the planer of the grooving and cutting machine to groove the metal sheet according to the preset program. The planer of the grooving and cutting machine performs at least one grooving operation on the same groove to make the shape and size of the groove on the metal sheet meet the predetermined requirements.

[0064] Step 2: If multiple grooves need to be cut into the metal sheet, repeat the operation of Step 1.

[0065] Step 3: After completing part or all of the grooving of the metal sheet, turn off the planer blade of the grooving and cutting machine, and start the laser cutting device or shearing device of the grooving and cutting machine to laser cut or shear the metal sheet into single metal sheets.

[0066] Preferably, in step one, if the planer of the grooving cutter performs two or more grooving operations on the same groove being processed, the planer also performs grooving operations during the return stroke of the planer mounting frame.

[0067] Preferably, in step three, after processing the predetermined number of grooves on the single metal sheet, the laser cutting device or shearing device of the grooving and cutting machine is started to cut the single metal sheet off, and then the next round of grooving and cutting is performed.

[0068] In step three, after all the grooves on the metal sheet are planed, the laser cutting device or shearing device of the grooving and cutting machine is started to cut them into individual metal sheets one by one.

[0069] In step one, the grooving and cutting machine can simultaneously perform two or more grooving processes on the metal sheet in the horizontal direction. That is, if two or more grooves need to be opened on a single metal sheet, the two or more grooves can be completed at one time.

[0070] Preferably, the longitudinal grooving centerline of the planer blade of the grooving cutter does not coincide with the longitudinal cutting centerline of the laser cutting head. Here, "longitudinal" refers to the running direction of the planer blade when grooving, and "transverse" refers to the direction perpendicular to "longitudinal" on the horizontal plane.
