Description

Technical Field

[0001] This invention relates to the field of metal processing, and in particular to a multi-specification sheet metal production line and production method. Background Technology

[0002] The manufacturing process of shipping containers requires the production of various specifications of panels, such as side panels, door panels, end panels, top panels, and bottom panels. Most of these panels undergo sandblasting, painting, and drying. After these processes, some panels, like the top panel, need to be directly cut to create flat panels; others, like the side panels, require pre-forming corrugated grooves before cutting; and still others, like the door panels, require perforation at specific locations within the corrugated panels. Current production methods assign one production line to each type of panel. However, due to varying quantity requirements for each panel, some production lines are prone to downtime, resulting in low equipment uptime and wasted production efficiency. Summary of the Invention

[0003] The present invention aims to solve at least one of the technical problems existing in the prior art. To this end, the present invention proposes a multi-specification sheet metal production line and production method.

[0004] According to a first aspect of the present invention, a multi-specification sheet metal production line includes, from left to right, a first uncoiling device, a sandblasting device, a roller coating and drying device, a roller device, a second shearing device, a punching device, and a punching and discharge device; a track-splitting mechanism is provided between the second shearing device and the punching device, the track-splitting mechanism including a first roller conveyor, an adjustable roller conveyor, a second roller conveyor, and a track-splitting discharge device, the first roller conveyor being connected to the second shearing device, and the second roller conveyor being connected to the punching device; the adjustable roller conveyor has a first state and a second state, in the first state the adjustable roller conveyor is connected between the first roller conveyor and the second roller conveyor, and in the second state the adjustable roller conveyor is connected between the first roller conveyor and the track-splitting discharge device.

[0005] According to the first aspect of the present invention, the multi-specification sheet metal production line has at least the following technical effects: by setting up a first uncoiling device, a sandblasting device, a roller coating and drying device, a roller device, a second shearing device, a punching device, and a punching and discharge device, the multi-specification sheet metal production line can produce perforated sheets. Moreover, by setting up a track-separating mechanism, the adjustable roller conveyor can be adjusted to a second state during production, so that the corrugated sheets before the punching device are conveyed to the track-separating discharge device, thus the multi-specification sheet metal production line can also produce corrugated sheets. When producing corrugated sheets or perforated sheets, the sandblasting device, the coating and drying device, and other devices do not need to be stopped, thereby increasing the equipment uptime and reducing waste of production efficiency.

[0006] According to some embodiments of the present invention, the first roller conveyor is arranged laterally, the left end of the adjustable roller conveyor is hinged to the right end of the first roller conveyor, and the hinge shaft at the hinge point extends forward and backward. The second roller conveyor and the track-separating discharge device are both located on the right side of the adjustable roller conveyor, and the track-separating discharge device is located below the second roller conveyor. This structure is simple, and the adjustable roller conveyor can switch between the first and second states by swinging up and down, which is convenient for operation.

[0007] According to some embodiments of the present invention, the track-separated discharge device includes a receiving platform, the bottom of which is provided with a translation mechanism. The left end of the receiving platform is located below the right end of the adjustable roller conveyor, and a receiving stop is provided on the upper side of the right end of the receiving platform. The receiving stop prevents the plate from moving to the right and protruding beyond the receiving platform due to inertia.

[0008] According to some embodiments of the present invention, the receiving stop is slidably connected to the receiving platform in the left and right directions. This allows the receiving stop to flatten the plate being transferred to the receiving platform.

[0009] According to some embodiments of the present invention, there are two track-splitting mechanisms, referred to as the first track-splitting mechanism and the second track-splitting mechanism, respectively. The second track-splitting mechanism is located between the second shearing device and the punching device. The first shearing device and the first track-splitting mechanism are sequentially arranged between the roller coating drying device and the roller device. This multi-specification sheet metal production line can also produce flat sheets.

[0010] According to some embodiments of the present invention, a plate welding device is provided between the first uncoiling device and the sand-blasting device. The plate welding device can be used to connect the ends of two coils of strip steel. When the previous coil of strip steel is used up, the end of the previous coil of strip steel can be welded to the front end of the next coil of strip steel, so that production can continue.

[0011] According to some embodiments of the present invention, a second uncoiling device is provided beside the first uncoiling device, and a rail-closing device is provided between the first uncoiling device and the panel welding device. The rail-closing device includes a third roller conveyor, a fourth roller conveyor, a fifth roller conveyor, and a rail-closing mechanism. The rail-closing mechanism has two positioning rollers, which are arranged vertically at intervals. The space between the two positioning rollers is called the rail-closing space. One end of the third roller conveyor is connected to the first uncoiling device, and the other end faces the left side of the rail-closing space. One end of the fourth roller conveyor is connected to the second uncoiling device, and the other end faces the left side of the rail-closing space. The fifth roller conveyor is connected between the right side of the rail-closing space and the panel welding device. By adding the second uncoiling device and the rail-closing mechanism, the first and second uncoiling devices can operate alternately. When the sheet material in one uncoiling device is about to be used up, a new sheet material can be pre-installed in the other uncoiling device so that the new sheet material can be quickly supplied, reducing waste of efficiency.

[0012] According to some embodiments of the present invention, a third shearing device and a transition roller conveyor are sequentially arranged between the second uncoiling device and the fourth roller conveyor. The transition roller conveyor extends laterally, and a lifting platform is provided at the bottom of the transition roller conveyor. By setting up the third shearing device and the transition roller conveyor, when the first uncoiling device is supplying sheet material and the second uncoiling device is idle, the sheet material for producing the base plate can be loaded onto the second uncoiling device and uncoiled. Then, the third shearing device cuts the sheet material, and the cut sheet material is placed on the transition roller conveyor. The transition roller conveyor gradually descends, allowing the cut sheet material to be stacked on the transition roller conveyor and then transported out by a forklift or other handling equipment. In this way, the present invention can also produce the base plate.

[0013] A method for producing multi-specification sheet metal according to a second aspect of the present invention includes the following steps:

[0014] Step a: Unroll the book;

[0015] Step b, sandblasting;

[0016] Step c: Roll coating and drying, then the sheet is transferred to the first shearing device;

[0017] Step d: Determine whether to manufacture a flat plate. If yes, proceed to steps e and g; otherwise, proceed to steps f and h.

[0018] Step e: The first shearing device cuts the board material and then transfers the cut board material to the first track splitting mechanism.

[0019] Step f: The first shearing device does not cut the sheet metal, but instead conveys the sheet metal to the first track-splitting mechanism after it passes through the first shearing device.

[0020] Step g: Adjust the first track splitting mechanism so that the sheet material transmitted from the first shearing device can be transferred to the track splitting discharge device of the first track splitting mechanism.

[0021] Step h: Adjust the first rail-splitting mechanism so that the sheet metal transmitted from the first shearing device can be transferred to the roller device;

[0022] Step i: Roller forming is performed using a roller device;

[0023] Step j: The sheet material from the roller device is transferred to the second shearing device for cutting, and then transferred to the second track splitting mechanism;

[0024] Step k: Determine whether to manufacture a wave plate. If yes, proceed to step l; otherwise, proceed to step m.

[0025] Step 1: Adjust the second rail splitting mechanism so that the sheet material transmitted from the second shearing device can be transferred to the rail splitting discharge device of the second rail splitting mechanism.

[0026] Step m: Adjust the second rail splitting mechanism so that the sheet metal transmitted from the second shearing device can be transferred to the punching device;

[0027] Step n: Punch holes using a punching device, and then transfer the punched sheet to the punching discharge device.

[0028] According to the second aspect of the present invention, the method for producing multi-specification plates has at least the following technical effects: by using the method for producing multi-specification plates of the present invention, a flat plate can be obtained in step g, a corrugated plate can be obtained in step l, and a perforated plate can be obtained in step n, thereby achieving the purpose of producing plates of multiple specifications. Moreover, when producing plates of multiple specifications, the sandblasting device and the painting and drying device do not need to be stopped, thereby increasing the equipment uptime and reducing the waste of production efficiency.

[0029] In some embodiments of the present invention, in step a, a first uncoiling device is used to uncoil a first sheet material to obtain a second sheet material, and a second uncoiling device is used to uncoil a second sheet material. The head end of the first sheet material and the tail end of the second sheet material are then joined and welded together. This facilitates continuous production.

[0040] The following is for reference. Figures 1 to 3A multi-specification sheet metal production line and production method are described according to embodiments of the present invention.

[0041] The multi-specification sheet metal production line according to a first aspect of the present invention includes seven main line devices, which are arranged sequentially from left to right: a first uncoiling device 005, a sandblasting device 012, a roller coating and drying device 013, a roller device 017, a second shearing device 018, a punching device 020, and a punching and unloading device 021. A track-splitting mechanism is provided between the punching device 020 and the second shearing device 018. The track-splitting mechanism includes a track-splitting unloading device, a second roller conveyor 163, a first roller conveyor 161, and an adjustable roller conveyor 162. The second shearing device 018 is connected to the first roller conveyor 161, and the punching device 020 is connected to the second roller conveyor 163. The adjustable roller conveyor 162 has a second state and a first state. In the second state, the adjustable roller conveyor 162 is connected between the track-splitting unloading device and the first roller conveyor 161. In the first state, the adjustable roller conveyor 162 is connected between the second roller conveyor 163 and the first roller conveyor 161.

[0042] For example, such as Figure 1 As shown, the punching and discharge device 021, punching device 020, track separating mechanism, second shearing device 018, roller device 017, roller coating and drying device 013, sandblasting device 012, and first uncoiling device 005 can all be installed on the floor of the factory workshop; the first uncoiling device 005, sandblasting device 012, roller coating and drying device 013, roller device 017, second shearing device 018, track separating mechanism, punching device 020, and punching and discharge device 021 are arranged sequentially from left to right. The sandblasting device 012 can be a conventional sandblasting machine, the first uncoiling device 005 can be a conventional uncoiling machine, the roller coating and drying device 013 can be a combination of a conventional roller coating machine and a drying room, the roller device 017 can be a conventional roller machine, the second shearing device 018 can be a conventional shearing machine, and the punching device 020 can be a conventional punching machine. The above-mentioned uncoiling machine, sandblasting machine, roller coating machine, drying room, roller machine, shearing machine, and punching machine are all commonly used equipment in this field, and their structures will not be described in detail here.

[0043] A conveying channel is provided between two adjacent main line units. The conveying channel is a conveying space for the passage of sheet metal between adjacent main line units. The conveying channel can be a suspended space that can transport long strip-shaped sheet metal. The conveying channel can also have roller conveyors at its bottom, which can serve as a support. In this way, the conveying channel can transport not only long strip-shaped sheet metal, but also sheet metal cut into plate shapes. A clamping device can be installed on any conveying channel to provide power for the conveying of sheet metal. The clamping device includes two clamping rollers arranged vertically and horizontally, at least one of which is a drive roller driven by an electric motor. The sheet metal is clamped between the two clamping rollers to obtain power for conveying. A leveling machine can be installed on any conveying channel to perform cold leveling of the sheet metal, so that the bent and deformed steel plate obtains a uniform and flat surface. A vertical guide device can be installed on any conveying channel to prevent the sheet metal from shifting in the front-back direction. The vertical guide device includes four vertically arranged guide rollers arranged in a rectangular array. The sheet metal passes between the four guide rollers.

[0044] The conveying channel between the punching device 020 and the second shearing device 018 is called the second channel. The second channel extends laterally. The bottom of the second channel is provided with a second roller conveyor 163, an adjustable roller conveyor 162 and a first roller conveyor 161. The first roller conveyor 161 extends laterally, and the left end of the first roller conveyor 161 is connected to the second shearing device 018.

[0045] The second roller conveyor 163 extends laterally, and its right end is connected to the punching device 020. The second roller conveyor 163 is located in the extension direction of the first roller conveyor 161, and the second roller conveyor 163 and the first roller conveyor 161 are spaced apart. The adjustable roller conveyor 162 is located between the second roller conveyor 163 and the first roller conveyor 161. When the adjustable roller conveyor 162 is in the first state, it is arranged laterally. When the adjustable roller conveyor 162 is in the second state, it is inclined downward from left to right. The track-separating discharge device is located below the second roller conveyor 163. Of course, the track-separating discharge device can also be located in front of, behind, above or other positions of the second roller conveyor 163. When the adjustable roller conveyor 162 is in the second state, it can extend from the first roller conveyor 161 to the right front, right rear, or right upper accordingly.

[0046] By setting up seven main line devices, the multi-specification sheet metal production line can produce perforated sheets. Furthermore, by setting up a track-splitting mechanism, the adjustable roller conveyor 162 can be adjusted to a second state during production, allowing the corrugated sheets before the punching device 020 to be conveyed to the track-splitting discharge device, thus enabling the multi-specification sheet metal production line to also produce corrugated sheets. When producing corrugated or perforated sheets, devices such as the sandblasting device 012 and the painting and drying device do not need to be stopped, increasing equipment uptime and reducing wasted production efficiency. Specifically, a double-sided shearing device can be installed between the track-splitting mechanism and the second shearing device 018 to cut the front and rear edges of the corrugated sheets to meet the front and rear dimensional requirements. The double-sided shearing device can be composed of two conventional shearing machines, with the two shearing machines spaced apart and facing each other.

[0047] In some embodiments of the present invention, the first roller conveyor 161 is arranged laterally, and the right end of the first roller conveyor 161 is hinged to the left end of the adjustable roller conveyor 162. The hinge shaft at the hinge point extends forward and backward. The track-separating discharge device and the second roller conveyor 163 are both located on the right side of the adjustable roller conveyor 162, and the track-separating discharge device is located below the second roller conveyor 163. (Refer to...) Figure 2 The bottom of the adjustable roller conveyor 162 is provided with a first driving device 164 for driving the adjustable roller conveyor 162. The first driving device 164 includes a first base and a first cylinder. The first base is fixedly installed on the ground, the cylinder body of the first cylinder is hinged to the first base, and the piston rod of the first cylinder is hinged to the adjustable roller conveyor 162. This structure is simple, and the adjustable roller conveyor 162 can switch between the first state and the second state by swinging up and down, which is convenient for operation.

[0048] In some embodiments of the present invention, the track-discharging device includes a receiving platform 165, a receiving stop 166 is provided on the upper right side of the receiving platform 165, the left end of the receiving platform 165 is located below the right end of the adjustable roller conveyor 162, and a translation mechanism is provided at the bottom of the receiving platform 165. The translation mechanism includes a conveying track extending forward and backward and a track wheel provided at the bottom of the receiving platform 165. The conveying track is fixedly installed on the ground, and the track wheel is provided on the conveying track, so the receiving platform 165 can move forward and backward to deliver the corrugated plate. Of course, the translation mechanism can also extend to the left, right, or other directions, as long as it can move the receiving platform 165 out. When the adjustable roller conveyor 162 is in the second state, the right end of the adjustable roller conveyor 162 and the receiving stop 166 are spaced apart on the left and right, and a receiving space is provided between the right end of the adjustable roller conveyor 162 and the receiving stop 166. When the plate is sent out from the adjustable roller conveyor 162, it can move into the receiving space. The setting of the receiving stop 166 can prevent the plate from moving to the right under the action of inertia and protruding out of the receiving platform 165.

[0049] In some embodiments of the present invention, the receiving platform 165 and the receiving stop 166 are slidably connected left and right. The receiving stop 166 and the receiving platform 165 can be slidably connected by a guide rail slider mechanism, a linear bearing mechanism, or other suitable mechanisms. The receiving platform 165 is provided with a second cylinder for driving the receiving stop 166; in this way, the receiving stop 166 can flatten the plate conveyed to the receiving platform 165; the structure of the punching and discharge device 021 can be the same as the structure of the rail-separated discharge device.

[0050] In some embodiments of the present invention, there are two track-splitting mechanisms, referred to as the second track-splitting mechanism 019 and the first track-splitting mechanism 016, respectively. A first shearing device 015 and the first track-splitting mechanism 016 are sequentially arranged between the roller coating drying device 013 and the roller device 017; the second track-splitting mechanism 019 is located between the punching device 020 and the second shearing device 018. The first shearing device 015 is a conventional shearing machine, which allows sheet metal to pass directly through it when not in operation; thus, the multi-specification sheet metal production line can also produce flat sheet metal. A looper 014 can also be provided between the first shearing device 015 and the roller coating drying device 013. The looper 014 provides a buffer zone between the first shearing device 015 and the roller coating drying device 013, allowing for speed adjustment of the steel strip entering the first shearing device 015.

[0051] In some embodiments of the present invention, a plate welding device 010 is provided between the sand-blasting device 012 and the first uncoiling device 005. The plate welding device 010 can be a conventional plate welding machine, and its specific structure will not be described in detail here. By providing the plate welding device 010, the plate welding device 010 can be used to connect the ends of two coils of strip steel. When the previous plate coil is used up, the end of the previous plate coil can be welded to the front end of the next plate coil, so that production can continue. A head-cutting shearing machine can be provided at the outlet of the first uncoiling device 005 to cut the front end of the next plate coil flat, and a tail-cutting shearing machine can be provided at the inlet of the plate welding device 010 to cut the rear end of the previous plate coil flat, which facilitates subsequent welding.

[0052] In some embodiments of the present invention, a rail-closing device is provided between the panel welding device 010 and the first uncoiling device 005. A second uncoiling device 001 is provided next to the first uncoiling device 005. The rail-closing device includes a rail-closing mechanism 008, a fifth roller conveyor 009, a fourth roller conveyor, and a third roller conveyor 007. The rail-closing mechanism is provided with two positioning rollers. The space between the two positioning rollers is called the rail-closing space. The two positioning rollers are arranged vertically at intervals. One end of the third roller conveyor 007 is connected to the first uncoiling device 005, and the other end faces the left side of the rail-closing space. One end of the fourth roller conveyor is connected to the second uncoiling device 001, and the other end faces the left side of the rail-closing space. The fifth roller conveyor 009 is connected between the right side of the rail-closing space and the panel welding device 010. It is important to note that if only one uncoiling device is installed, when the current sheet material roll is used up, a new sheet material roll needs to be installed on the uncoiling device before the next sheet material roll can be uncoiled. During this time, the production line has to stop operating, resulting in wasted efficiency. In this embodiment, by adding a second uncoiling device 001 and a rail-closing mechanism 008, the first uncoiling device 005 and the second uncoiling device 001 can operate alternately. When the sheet material roll in one uncoiling device is about to be used up, a new sheet material roll can be pre-installed on the other uncoiling device so that the new sheet material roll can be quickly supplied, reducing wasted efficiency. Among them, the third roller conveyor 007 and the fifth roller conveyor 009 are both arranged horizontally and on the same plane. The fourth roller conveyor is provided with an inclined section 006, which is located above the third roller conveyor 007. The inclined section 006 is inclined downward from left to right, so that the sheet material at the inclined section 006 and the sheet material at the third roller conveyor 007 can be conveyed to the right into the rail-closing space.

[0053] In some embodiments of the present invention, a third shearing device 002 and a transition roller conveyor 003 are sequentially arranged between the second unwinding device 001 and the fourth roller conveyor. The transition roller conveyor 003 extends laterally, and a lifting platform is provided at the bottom of the transition roller conveyor 003. The fourth roller conveyor is provided with a transverse section 004, the right end of which is connected to the left end of the inclined section 006. The transverse section 004 can cross over the first unwinding device 005, and the transition roller conveyor 003 is located to the left of the transverse section 004.

[0054] The third shearing device 002 is located on the left side of the transition roller conveyor 003, and the second uncoiling device 001 is located on the left side of the third shearing device 002. The second uncoiling device 001 can be a conventional uncoiling machine, and the third shearing device 002 can be a conventional shearing machine. Their structures will not be described in detail here.

[0055] It is important to note that during the container manufacturing process, a base plate also needs to be manufactured. The base plate is a flat, thick sheet that does not require sanding, painting, or drying processes; it can be directly cut. In this embodiment, by setting up a transition roller conveyor and a third shearing device 002, when the first uncoiling device 005 is supplying sheet material and the second uncoiling device 001 is idle, the sheet material for producing the base plate can be loaded onto the second uncoiling device 001 and uncoiled. Then, the third shearing device 002 cuts the sheet material. The cut sheet material is placed on the transition roller conveyor, which gradually descends, allowing the cut sheet material to be stacked on top of the conveyor and then transported out by forklift or other handling equipment. In this way, the present invention can also produce the base plate. Since the sheet material supplied by the first uncoiling device 005 needs to go through the sanding device 012 and the roller coating and drying device 013, its consumption rate is relatively slow. However, the production of the base plate only requires cutting, and the sheet material consumption rate is relatively fast. Therefore, the production of the base plate can be completed during the interval between the alternation of the two uncoiling devices without affecting the production of other sheet materials.

[0056] The method for producing multi-specification sheet metal according to a second aspect of the present invention uses a multi-specification sheet metal production line to produce sheet metal, as described below. Figure 3 The production method includes the following steps:

[0057] Step a: Unroll the book;

[0058] Step b, sandblasting: The plate from step a is transferred to the sandblasting device 012 for sandblasting.

[0059] Step c, roller coating and drying: The sheet material from step b is transferred to the roller coating and drying device 013 for roller coating and drying, and then the sheet material is transferred to the first shearing device 015.

[0060] Step d: Determine whether to manufacture a flat plate. If yes, proceed to steps e and g; otherwise, proceed to steps f and h.

[0061] Step e: The first shearing device 015 cuts the board material and then transfers the cut board material to the first track splitting mechanism 016.

[0062] Step f: The first shearing device 015 does not cut the board material, but allows the board material to pass through the first shearing device 015 and be conveyed to the first track-splitting mechanism 016.

[0063] Step g: Adjust the first track splitting mechanism 016 to the second state so that the plate material transmitted from the first shearing device 015 can be transmitted to the track splitting discharge device of the first track splitting mechanism 016.

[0064] Step h: Adjust the first rail splitting mechanism 016 to the first state so that the sheet metal transmitted from the first shearing device 015 can be transmitted to the roller device 017;

[0065] Step i: Roller forming of the sheet material from step h using roller device 017;

[0066] Step j: The sheet material from the roller device 017 is transferred to the second shearing device 018 for cutting, and then transferred to the second track splitting mechanism 019.

[0067] Step k: Determine whether to manufacture a wave plate. If yes, proceed to step l; otherwise, proceed to step m.

[0068] Step 1: Adjust the second track splitting mechanism 019 to the second state so that the sheet material transmitted from the second shearing device 018 can be transmitted to the track splitting discharge device of the second track splitting mechanism 019.

[0069] Step m: Adjust the second rail splitting mechanism 019 to the first state so that the plate material transmitted from the second shearing device 018 can be transmitted to the punching device 020.

[0070] Step n: Punch holes using punching device 020, and then transfer the punched plate to punching discharge device 021.

[0071] When producing flat plates, steps a, b, c, d, e, and g can be executed sequentially. Step d can be performed at any time before step e and does not necessarily have to be performed after step c. When producing corrugated plates, steps a, b, c, d, f, h, i, j, k, and l can be executed sequentially. Step d can be performed at any time before step f and does not necessarily have to be performed after step c.

When producing perforated plates, steps a, b, c, d, f, h, i, j, k, m, and n can be executed sequentially. Step d can be performed at any time before step f and does not necessarily have to be performed after step c. Step k can be performed at any time before step m and does not necessarily have to be performed after step j.

[0072] By using the multi-specification panel production method of the present invention, a flat panel can be obtained in step g, a corrugated panel can be obtained in step l, and a perforated panel can be obtained in step n, thus achieving the purpose of producing panels of various specifications. Furthermore, when producing panels of various specifications, the sandblasting device 012 and the painting and drying device do not need to be shut down, increasing the equipment uptime and reducing production waste. It should be noted that the sandblasting device 012 and the painting and drying device are large pieces of equipment, and restarting them requires a significant amount of energy. However, the present invention allows for the production of various panels without requiring the shutdown of the sandblasting device 012 and the painting and drying device, demonstrating excellent potential for widespread application.

[0073] According to some embodiments of the present invention, in step a, a second unwinding device 001 is used to unwind the material to obtain a second sheet, and a first unwinding device 005 is used to unwind the material to obtain a first sheet. The head end of the first sheet is then welded to the tail end of the second sheet. This facilitates continuous production.

[0074] The preferred embodiments of the present invention have been described in detail above, but the present invention is not limited to the embodiments. Those skilled in the art can make various equivalent modifications or substitutions without departing from the spirit of the present invention, and these equivalent modifications or substitutions are all included within the scope defined by the claims of this application.
