A self-correcting automated production line for coiled sheet materials

Abstract

This invention discloses a self-correcting automated production line for processing coiled sheet metal, including a cutting machine tool. Along the transmission direction of the cutting machine tool, a feeding station, a leveling station, and a cutting station are sequentially arranged. The cutting station, from left to right, includes a coil positioning mechanism for aligning the coiled sheet metal during the initial feeding stage, a coil clamping mechanism for pressing the positioned coiled sheet metal, and a coil cutting mechanism that works in conjunction with the clamping mechanism to cut the clamped sheeted sheet metal to predetermined dimensions. All three mechanisms are mounted on the cutting machine tool. This invention uses the coil positioning mechanism to adjust the sheet metal position. When the ejector pin coincides with the saw teeth, the saw teeth press the ejector pin into the reference plate, preventing interference. This solves the problem of slight deviations in the placement of the leveling machine and the cutting machine, which can cause the leveling machine to shift its material after feeding it to the cutting machine tool.

Description

Technical Field

[0001] This invention belongs to the field of laser cutting equipment technology. Specifically, this invention relates to an automated production line for self-correcting coiled sheet materials. Background Technology

[0002] Laser cutting involves focusing a laser beam emitted from a laser source into a high-power-density laser beam through an optical path system. The laser beam irradiates the surface of the workpiece, causing the workpiece to reach its melting or boiling point. Simultaneously, high-pressure gas coaxial with the beam blows away the molten or vaporized metal. As the relative position of the beam and the workpiece moves, a kerf is eventually formed in the material, thus achieving the purpose of cutting.

[0003] With the development of this industry, laser cutting machines have begun to be widely used in the sheet metal industry. In order to improve efficiency and reduce material turnover time, the three-in-one mode of uncoiling, leveling and cutting is gradually being adopted in the field of thin plates.

[0004] Patent CN110900013B discloses a coil laser cutting machine, including a coil of metal sheet, a leveling machine, a main frame base, a servo motor, a reducer, a rack, a slider rail, a Y-axis moving plate, a crossbeam, a chain drive tip support platform, a feeding platform, a feeding frame, and an electromagnetic feeding mechanism. One end of the coil of metal sheet passes through the leveling machine and extends to the chain drive tip support platform. The chain drive tip support platform is located at the top center of the main frame base. The top two sides of the main frame base, near the leveling machine, are equipped with the slider rail and the rack located outside the slider rail. The reducer is located at the end of the slider rail near the leveling machine, and a servo motor is located on top of each reducer. Beneficial effects: Reduces the time cost of manual material cutting, loading and unloading, and machine start-up and shutdown; significantly reduces material waste; and increases the service life of the crossbeam.

[0005] However, the above-mentioned patents have the following drawbacks:

[0006] 1. Because there may be slight deviations when the leveling machine and the cutting machine are placed, the material fed by the leveling machine to the cutting machine will be offset. It is necessary to align the rolled material at the beginning of the feeding process of the machine bed.

[0007] Second, because the contact area between the saw teeth and the board is small and the edges are sharp, during the rapid start-up and acceleration phase of the motor, due to the low friction, relative sliding often occurs between the saw teeth and the board, causing scratches on the board and affecting the accuracy of the feeding length. Summary of the Invention

[0008] This invention provides a self-correcting automated production line for coiled sheet materials, which solves the problems mentioned in the background section.

[0009] To achieve the above objectives, the technical solution adopted by the present invention is as follows: a self-correcting automatic processing production line for coiled sheet metal, including a cutting machine tool, and a feeding station, a leveling station and a cutting station are sequentially arranged along the transmission direction of the cutting machine tool;

[0010] The cutting station is provided from left to right with a roll positioning mechanism for aligning the roll at the initial feeding stage of the bed, a roll pressing mechanism for pressing the positioned roll, and a roll cutting mechanism that works with the roll pressing mechanism to cut the pressed roll according to a predetermined size. The roll positioning mechanism, the roll pressing mechanism, and the roll cutting mechanism are all mounted on the cutting machine tool.

[0011] The coil positioning mechanism includes a mounting assembly disposed on a cutting machine tool and a positioning assembly mounted on the mounting assembly for positioning the coil located below the mounting assembly.

[0012] The coil pressing mechanism includes a support component mounted on the cutting machine tool and a pressure component slidably mounted on the support component for pressing the coil passing under the support component to increase the friction between the sheet and the saw teeth.

[0013] Preferably, the mounting assembly includes two sets of mounting seats symmetrically mounted on the cutting machine tool, bearings with vertical seats mounted on both sides of the mounting seats, a slide rod mounted between two corresponding bearings with vertical seats, bushings sleeved on both ends of the slide rod surface, and a spring a sleeved on one end of the slide rod.

[0014] One end of the spring a is in contact with one side of the bushing, and the other end is in contact with the positioning component.

[0015] Preferably, the positioning component is provided in four sets, and is respectively sleeved on both ends of the two slide rods. It includes a linear bearing sleeved on the slide rod, a reference plate sleeved on the outer end of the linear bearing, and an outer chuck that engages with the reference plate.

[0016] Preferably, the reference plate has a groove along the circumferential direction, a pin is inserted in the groove, a spring b is provided between the pin and the groove, and the outer chuck has a slot adapted to the pin.

[0017] Preferably, the support assembly includes two sets of bases mounted on the cutting machine tool, a cylinder mounting plate mounted on the two sets of bases, and a sliding groove formed on the cylinder mounting plate.

[0018] Preferably, the pressurization assembly includes a cylinder that is slidably disposed with the slide groove, a mounting plate connected to the output end of the cylinder, and omnidirectional balls evenly arranged at the bottom of the mounting plate.

[0019] Preferably, the roll material cutting mechanism includes a transverse carriage slidably disposed on the cutting machine tool, a transverse drive unit for driving the transverse carriage to move along the length direction of the cutting machine tool, a longitudinal carriage slidably disposed on the transverse carriage, a longitudinal drive unit for driving the longitudinal carriage to move on the transverse carriage, and a laser cutting head that can be lifted and lowered on the longitudinal carriage.

[0020] Preferably, the unwinding station is provided with an unwinding mechanism for winding / unwinding the roll material, a material support arm for supporting the unwinding mechanism, and a loading trolley for transporting and loading the roll material.

[0021] Preferably, the leveling station is equipped with a leveling mechanism for leveling the unwound roll.

[0022] The beneficial effects of adopting the above technical solutions are:

[0023] 1. When a new sheet is placed on the rolling table, the position of the sheet is adjusted by the roll positioning mechanism. When the rolling table feeds the sheet, it drives the positioning plate assembly to rotate. When the ejector pin just coincides with the saw teeth, the saw teeth will press the ejector pin into the reference plate to avoid mutual interference. This solves the problem that the sheet fed by the leveler to the cutting machine will be offset because there will be slight deviations when the leveler and the cutting machine are placed.

[0024] Second, the universal ball in the coil clamping mechanism contacts the sheet material and applies appropriate pressure to increase the friction between the sheet material and the saw teeth, ensuring that the two will not slide during the feeding acceleration phase of the worktable; and when the width of the sheet material changes, the position of the cylinder can be adjusted as needed.

Detailed Implementation

[0037] The specific embodiments of the present invention will be further described in detail below with reference to the accompanying drawings, in order to help those skilled in the art to have a more complete, accurate and in-depth understanding of the concept and technical solutions of the present invention, and to facilitate its implementation. Example

[0038] Specifically, such as Figures 1 to 3 As shown, a self-correcting automatic processing production line for coiled sheet includes a cutting machine tool 100, and a feeding station, a leveling station and a cutting station are arranged sequentially along the transmission direction of the cutting machine tool 100.

[0039] The cutting station is provided from left to right with a roll positioning mechanism 1 for aligning the roll at the initial feeding stage of the bed, a roll pressing mechanism 2 for pressing the positioned roll, and a roll cutting mechanism 3 for cutting the pressed roll according to a predetermined size in conjunction with the roll pressing mechanism 2. The roll positioning mechanism 1, the roll pressing mechanism 2, and the roll cutting mechanism 3 are all mounted on the cutting machine tool 100.

[0040] The coil positioning mechanism 1 includes a mounting assembly 11 disposed on the cutting machine tool 100 and a positioning assembly 12 mounted on the mounting assembly 11 and used for positioning the coil located below the mounting assembly 11.

[0041] The coil pressing mechanism 2 includes a support component 21 disposed on the cutting machine tool 100 and a pressure component 22 slidably disposed on the support component 21 and used to press the coil passing under the support component 21 to increase the friction between the plate and the saw teeth.

[0042] It should be noted that the roll material is first loaded onto the unloading station and unwound to the leveling station. The roll material is then leveled at the leveling station and finally transferred to the cutting machine 100 and cut into the corresponding size at the cutting station.

[0043] In detail, when the coil passes under the mounting component 11, the positioning component 12 aligns the position of the coil to prevent it from shifting. Then, the corrected coil passes under the support component 21, and the pressure component 22 applies a certain pressure to the coil to increase the friction between the coil and the saw teeth, ensuring that the two do not slide during the feeding acceleration phase of the worktable.

[0044] like Figures 4 to 6 As shown, the mounting assembly 11 includes two sets of mounting seats 111 symmetrically mounted on the cutting machine tool 100, bearings 112 with vertical seats mounted on both sides of the mounting seats 111, a slide rod 113 mounted between two corresponding bearings 112 with vertical seats, bushings 114 sleeved on both ends of the surface of the slide rod 113, and a spring a115 sleeved on one end of the slide rod 113.

[0045] One end of the spring a115 is in contact with one side of the bushing 114, and the other end is in contact with the positioning component 12.

[0046] The positioning component 12 is provided in four sets and is respectively sleeved on both ends of the two slide rods 113. It includes a linear bearing 121 sleeved on the slide rod 113, a reference plate 122 sleeved on the outer end of the linear bearing 121, and an outer chuck 123 engaged with the reference plate 122.

[0047] The reference plate 122 has a groove 124 along the circumferential direction, a pin 125 is inserted into the groove 124, and a spring b126 is provided between the pin 125 and the groove 124. The outer chuck 123 has a slot 127 that matches the pin 125.

[0048] It should be noted that, first, the linear bearing 121 is installed in the reference plate 122, then the spring b126 is placed in the groove 124 of the reference plate 122, then the ejector pin 125 is placed in the groove 124 of the reference plate 122 to press down the spring b126, then the outer chuck 123 is clamped on the reference plate 122, and finally the positioning assembly 12, bushing 114, spring a115, and bearing 112 with vertical seat are fitted onto the slide rod 113, and then installed on the mounting base 111, and finally the whole assembly is installed on the cutting machine tool 100;

[0049] In detail, when loading new coil material, the positioning component 12 on one side is placed in the designated position so that the side of the ejector pin 125 contacts the edge of the coil material and the outer chuck 123 contacts the top of the coil material. The two positioning components 12 are adjusted so that the tangential direction of the ejector pin 125 is parallel to the direction of movement of the rolling table, and then fixed with the bushing 114. On the other side, the side of the ejector pin 125 contacts the edge of the coil material and the outer chuck 123 contacts the top of the coil material. The spring a115 applies a pushing force to the positioning component 12, and the bushing 114 is moved to the appropriate position and then fixed. Example

[0050] Specifically, such as Figures 7 to 8 As shown, the support assembly 21 includes two sets of bases 211 mounted on the cutting machine tool 100, a cylinder mounting plate 212 mounted on the two sets of bases 211, and a slide groove 213 formed on the cylinder mounting plate 212.

[0051] The pressurization assembly 22 includes a cylinder 221 that is slidably disposed with a slide groove 213, a mounting plate 222 connected to the output end of the cylinder, and omnidirectional balls 223 that are evenly arranged at the bottom of the mounting plate 222.

[0052] It should be noted that the cylinder mounting plate 212 is first installed on the base 211, then the cylinder 221 is installed on the cylinder mounting plate 212, the omnidirectional ball 223 is installed on the mounting plate 222, then the mounting plate 222 is installed on the cylinder 221, and finally the assembled coil pressing mechanism 2 is installed on the bed.

[0053] In addition, when the width of the roll changes, the position of cylinder 221 can be adjusted as needed. When changing the roll, repeat the above operation.

[0054] Specifically, such as Figures 9 to 10 As shown, the roll material cutting mechanism 3 includes a transverse slide 31 slidably disposed on the cutting machine tool 100, a transverse drive unit 32 for driving the transverse slide 31 to move along the length direction of the cutting machine tool 100, a longitudinal slide 33 slidably disposed on the transverse slide 31, a longitudinal drive unit 34 for driving the longitudinal slide 33 to move on the transverse slide 31, and a laser cutting head 35 that can be lifted and lowered on the longitudinal slide 33.

[0055] It should be noted that when the roll material is transported to the bottom of the roll material cutting mechanism 3, the control system controls the transverse drive unit 32 and the longitudinal drive unit 34 to move the transverse slide 31 and the longitudinal slide 33 to the appropriate position, and finally the cutting work is completed by the laser cutting head 35.

[0056] Specifically, such as Figures 1 to 10As shown, the unwinding station is equipped with an unwinding mechanism 4 for winding / unwinding the roll material, a material support arm 5 for supporting the unwinding mechanism 4, and a loading trolley 6 for transporting and loading the roll material.

[0057] The leveling station is equipped with a leveling mechanism 7 for leveling the unwound roll.

[0058] Working principle:

[0059] When changing to a new roll after cutting the previous one, the roll is first placed on the loading trolley 6. The loading trolley 6 uses a hydraulic device to lift the roll, aligning the roll's axis with the center of the material rack's main shaft. Then, the motor of the loading trolley 6 loads the roll onto the material rack's main shaft. The hydraulic device then opens the main shaft, securing the inner wall of the roll. The material support arm 5 supports the main shaft, and finally, the material rack's pressing arm holds the roll down to prevent it from unraveling. Before feeding the roll from the material rack into the leveling mechanism 7 via the uncoiling mechanism 4, the alignment mechanism on the leveling mechanism 7 is adjusted. After passing through the alignment mechanism, the roll is fed into the leveling mechanism 7 for leveling. The leveled roll is then placed on the rolling table. First, ventilate cylinder 2221 in the coil pressing mechanism 2 to lift the omnidirectional ball 223. Then, according to the above operation, use the coil positioning mechanism 1 to determine the position of the coil, so that the coil exceeds the coil pressing mechanism 2 by a certain distance, ensuring that the mounting plate 222 covers the width of the coil within the coil. Then, ventilate cylinder 221 in the reverse direction to make the omnidirectional ball 223 in the coil pressing mechanism 1 contact the coil and apply appropriate pressure to increase the friction between the coil and the saw teeth, ensuring that the two will not slide during the feeding acceleration stage of the worktable. When the width of the coil changes, the position of cylinder 221 can be adjusted as needed. When changing the coil, repeat the above operation.

[0060] The present invention has been described above by way of example with reference to the accompanying drawings. Obviously, the specific implementation of the present invention is not limited to the above-described manner. Any non-substantial improvements made using the inventive concept and technical solution of the present invention, or the direct application of the inventive concept and technical solution of the present invention to other situations without modification, are all within the protection scope of the present invention.
