Description

Technical Field

[0001] This invention relates to the field of metal processing technology, and in particular to a metal processing workshop that integrates uncoiling, leveling, feeding, and fine blanking. Background Technology

[0002] Fine blanking, short for precision blanking, is an economical and effective metal shearing process that produces high-smoothness, tear-free blanked surfaces. Compared to ordinary punching, fine blanking has the following characteristics: it achieves high-quality blanked surfaces without shearing, grinding, or secondary machining; fine-bent parts have high dimensional accuracy; and it can be combined with other processes (such as stamping, bending, and forging) to form composite fine blanking. The emergence of fine blanking technology has rendered the two-in-one uncoiling and leveling machines and peripheral equipment previously used in ordinary stamping processes in the field of stamping automation inadequate for the requirements of high-precision automated stamping.

[0003] Because fine blanking technology started later than traditional stamping technology, some customers lack sufficient understanding of it and their approach to peripheral equipment for fine blanking machines remains based on traditional stamping technology. Some customers, perhaps prioritizing cost, often overlook the importance of uncoiling and leveling equipment before automated feeding in fine blanking. Their approach to uncoiling and leveling machines for fine blanking machines is merely a simple optimization and improvement of the two-in-one leveling machines used in traditional stamping processes. This optimization and improvement falls far short of meeting the basic requirements for automated feeding in fine blanking machines, mainly manifested in the following ways:

[0004] Firstly, since space needs to be left on the uncoiling drum's loading side for material loading, only one roller is usually set on the uncoiling drum's loading side as a material blocking device. This material blocking device is not strong enough, and when the uncoiling drum drives the coil to unwind and rotate, the coil will slightly deviate.

[0005] Secondly, the positional relationship between the uncoiler and the leveler cannot be adjusted. The feeding position of the coil material is uniform, and coil materials of different widths cannot all be centered when entering the leveler. The pressure rollers in the leveler can only be finely adjusted up and down to change the pressure. If the coil material is biased to one side of the pressure roller when feeding, the pressure roller will be subjected to uneven force, which is prone to shaft breakage accidents.

[0006] Third, the overall rigidity of the uncoiler is insufficient, and the design of the pressure arm, material support device, and material feeding device is unreasonable. During normal uncoiling and feeding, the roll material is prone to bursting due to its high yield strength, which prevents the material strip from being properly introduced into the feed clamping roller of the leveler.

[0007] Fourth, after the strip is leveled, the distance between the leveler and the fine blanking feeder is a material buffer zone (storage area). Ordinary two-in-one levelers often use conventional induction frames instead, which has limited performance and obviously cannot meet the requirements of fine blanking. Therefore, it is necessary to propose an improved technical solution to address the above problems. Summary of the Invention

[0008] To overcome the shortcomings mentioned above, the present invention aims to provide a technical solution that can solve the above problems.

[0009] A metal processing workshop integrating uncoiling, leveling, feeding, and fine blanking is provided. The workshop is equipped with an uncoiler, a leveler, a strip transfer machine, and a fine blanking machine, which are connected in sequence.

[0010] The uncoiler includes a base plate, a linear module mounted on the base plate, an uncoiler body powered by the linear module, and a lifting feeder connected to the base plate. The uncoiler body is equipped with an uncoiler drum for unwinding the coil, a pressing arm for pressing the unwinding end of the coil, a support arm for holding the unwinding end of the coil and directing it toward the leveling machine, and multiple fixed guide rollers located between the coil and the uncoiler body. The lifting feeder is located in front of the uncoiler drum. Driven by the linear module, the uncoiler body aligns the uncoiler drum with the lifting feeder for loading, or centers the coil on the uncoiler drum with the leveling machine. The base plate also includes a lifting mechanism for lifting the lifting feeder and a power transmission mechanism connected to the lifting mechanism.

[0011] The unwinding body is also equipped with a first material roller adjusting mechanism and a second material roller adjusting mechanism. The first material roller adjusting mechanism is poweredly connected to a first movable stop roller located between the unwinding drum and the lifting feed table. The base plate is also equipped with two symmetrically arranged opening and closing linear mechanisms. Each opening and closing linear mechanism is slidably connected to a material roller connecting seat. The opening and closing linear mechanism is poweredly connected to a power transmission mechanism, so that the power transmission mechanism drives the two material roller connecting seats to move relative to each other through the opening and closing linear mechanism. A T-shaped pull rod is also slidably connected between the two material roller connecting seats, and the direction in which the power transmission mechanism drives the material roller connecting seats to move is the same as the direction in which the material roller connecting seats slide along the T-shaped pull rod. The second material roller adjusting mechanism is used to pull the T-shaped pull rod to make the material roller connecting seats slide along the opening and closing linear mechanism. The two material roller connecting seats are hinged to a second movable stop roller located between the unwinding drum and the lifting feed table, and the other ends of the two second movable stop rollers are hinged together.

[0012] Preferably, the feed end of the leveler is connected to a feeding device, which includes a frame connected to the feed end of the leveler, an upper feeding frame rotatably connected to the frame, a lower feeding frame rotatably connected to the frame, a first cylinder hinged to the frame and used to drive the upper feeding frame to rotate, and a second cylinder hinged to the frame and used to drive the lower feeding frame to rotate. A middle plate and corresponding side plates are provided on the lower feeding frame. The middle plate is slidably connected to the lower feeding frame, and a pushing cylinder for pushing the middle plate to slide towards the uncoiling machine is also installed on the lower feeding frame.

[0013] Preferably, the strip transfer machine includes a lifting linear module fixedly installed in the workshop, a transfer frame powered by the lifting linear module, and transfer rollers evenly arranged on the transfer frame. The transfer frame is provided with a transfer panel and baffle walls located on both sides of the transfer panel. The transfer rollers are rotatably connected to the back of the transfer panel, and an opening is provided on the transfer panel for the transfer rollers to be exposed.

[0014] Compared with the prior art, the beneficial effects of the present invention are:

[0015] The uncoiling body, lifting feeder, and blocking device were redesigned and analyzed based on full automation. By setting the uncoiling body to be linearly movable, setting the lifting feeder to be lifting-only, and setting the blocking device to be fixed and movable and distributed on both sides of the uncoiling drum, the uncoiler can achieve fully automated feeding, automatic calibration of the discharge position, and more stable blocking and restriction on both sides of the coil. This allows the uncoiler to achieve more flexible operation and fully automated control, greatly reducing the geometric tolerance of the uncoiler discharge and improving the flexibility of the discharge position and the stability of the coil fixation.

[0016] The movable stop roller is configured as a first movable stop roller and a second movable stop roller. The first movable stop roller is based on a traditional structural design and adopts two second movable stop rollers that are hinged together. The position of the second movable stop roller is adjusted and stored by using an opening and closing linear mechanism, a roller connecting seat, a T-shaped pull rod, and a second roller adjustment mechanism. Furthermore, the lifting mechanism and the opening and closing linear mechanism are driven synchronously by a power transmission mechanism, which greatly improves the overall ingenuity of structural cooperation.

[0017] By connecting a feeding device at the feed end of the leveling machine, and by setting a middle plate and corresponding side plates on both sides of the middle plate on the lower feeding frame, the middle plate is slidably connected to the lower feeding frame, and a pushing cylinder for pushing the middle plate to slide towards the uncoiler is also installed on the lower feeding frame; by utilizing the cooperation between the middle plate and the side plates, the middle plate is pushed towards the uncoiler by the pushing cylinder, thereby extending the length of the lower feeding frame and enabling more flexible docking with the uncoiler;

[0018] By setting up a strip transfer machine to connect the leveling machine and the fine blanking machine, the design of the strip transfer machine replaces the induction frame in the traditional design. This not only improves the automation performance of the whole machine, but also makes it faster to introduce the strip into the fine blanking feeder. The operation of the lifting linear module is controlled by laser ranging. It accurately raises and lowers the transfer frame according to the height of the strip when the leveling machine outputs material, so that the leveling machine and the fine blanking machine are fully integrated, realizing fully automated and precise stamping, and the whole operation is smoother.

[0019] Additional aspects and advantages of the invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

[0031] The technical solutions in the embodiments of the present invention will be clearly and completely described below. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0032] Please see Figure 1-8 In this embodiment of the invention, a metal processing workshop integrating uncoiling, leveling, feeding and fine blanking is provided. The workshop is equipped with an uncoiling machine 10, a leveling machine 20, a strip transfer machine 30 and a fine blanking machine 40, which are connected in sequence.

[0033] The uncoiler 10 includes a base plate 11, a linear module 12 mounted on the base plate 11, an uncoiler body 13 poweredly connected to the linear module 12, and a lifting feed table 14 guided and connected to the base plate 11. The uncoiler body 13 is equipped with an uncoiler drum 131 for driving the roll to unwind, a pressing arm 132 for pressing the unwinding end of the roll, a support arm 133 for supporting the unwinding end of the roll and directing the unwinding end towards the leveling machine 20, and multiple fixed guide rollers 134 located between the roll and the uncoiler body 13. The uncoiler drum 131 is used to load the roll. The unwinding body 13 is equipped with a power mechanism for rotating the unwinding drum 131, and the power mechanism is equipped with a ring-type brake device to achieve precise material control. The lifting feed platform 14 is located in front of the unwinding drum 131. The unwinding body 13 is driven by the linear module 12 to make the unwinding drum 131 dock with the lifting feed platform 14 for loading, or to make the coil on the unwinding drum 131 dock with the leveling machine 20 in the center. The base plate 11 is also equipped with a lifting mechanism 15 that drives the lifting feed platform 14 to perform lifting action, and a power transmission mechanism 16 that is connected to the lifting mechanism 15.

[0034] A first material roller adjusting mechanism 135 and a second material roller adjusting mechanism 136 are also installed on the unwinding body 13. The first material roller adjusting mechanism 135 is poweredly connected to a first movable stop roller 137 located between the unwinding drum 131 and the lifting feed table 14. Two symmetrically arranged opening and closing linear mechanisms 17 are also installed on the base plate 11. Each opening and closing linear mechanism 17 is slidably connected to a material roller connecting seat 18. The opening and closing linear mechanism 17 is poweredly connected to the power transmission mechanism 16, so that the power transmission mechanism 16 drives the two material roller connecting seats 18 relative to each other through the opening and closing linear mechanism 17. The two roller connecting seats 18 are slidably connected by a T-shaped pull rod 181, and the direction in which the roller connecting seat 18 moves is the same as the direction in which the roller connecting seat 18 slides along the T-shaped pull rod 181. The second roller adjusting mechanism 136 is used to pull the T-shaped pull rod 181 to make the roller connecting seat 18 slide along the opening and closing linear mechanism 17. The two roller connecting seats 18 are hinged with a second movable stop roller 138 located between the unwinding drum 131 and the lifting feeding table 14, and the other ends of the two second movable stop rollers 138 are hinged together.

[0035] In the above technical solution, the unwinding body 13, the lifting feeding platform 14 and the blocking device are redesigned and analyzed based on full automation. The movable design of the unwinding body 13 is realized by adopting a linear module 12, so that the unwinding body 13 can be moved to the position of the lifting feeding platform 14 for loading through the linear module 12, and the unwinding body 13 can adjust the positional relationship between the roll material on the unwinding drum 131 and the leveling machine 20 through the linear module 12. Generally, the position is calibrated by a laser sensor so that roll materials of different sizes can be centered and docked with the pressure roller on the leveling machine 20.

[0036] Multiple fixed stop rollers 134 and multiple movable stop rollers are respectively located on both sides of the unwinding drum 131. The fixed stop rollers 134 are fixedly installed on the unwinding body 13. When the material roll is loaded onto the unwinding drum 131, it is positioned by abutting against the fixed stop rollers 134. The movable stop rollers are adjusted in position by the first material roll adjusting mechanism 135 and the second material roll adjusting mechanism 136 so that they abut against the other side of the loaded material roll. In order to have multiple movable stop rollers without affecting the loading operation, the movable stop rollers are configured as a first movable stop roller 137 and a second movable stop roller 138. The movable stop roller 137 is consistent with the traditional stop device, such as the three-in-one straightening and feeding machine and its straightening and feeding method described in patent application publication number CN103707068A, which describes the stop device therein; while the second movable stop roller 138 is driven by the opening and closing linear mechanism 17. By setting two mutually symmetrical opening and closing linear mechanisms 17, a slidable roller connecting seat 18 is set on the opening and closing linear mechanism 17 in the vertical direction. The second movable stop roller 138 is hinged by the roller connecting seat 18, and a T-shaped pull rod 181 is set to guide and connect the roller connecting seat 18, so that the opening and closing linear mechanism 17... While moving the two second movable guide rollers 138 to either side or closer to the unwinding body 13, the linear module 12 can also simultaneously push the material roller connecting seat 18 via the T-shaped pull rod 181 when the unwinding body 13 moves. Furthermore, the second material roller adjusting mechanism 136 can pull the T-shaped pull rod 181 to adjust the distance between the material roller connecting seat 18 and the unwinding body 13. The other ends of the two second movable guide rollers 138 are hinged, so that during the feeding process of the unwinding body 13, the opening and closing linear mechanism 17 can drive the two second movable guide rollers 138 to open relative to each other and move to the unwinding drum. At the position below the coil 131, after the coil is loaded, the opening and closing linear mechanism 17 drives the two second movable stop rollers 138 to close relative to each other, thereby moving them between the coil and the lifting feed table 14. Then, the second material roller adjustment mechanism 136 drives the second movable stop rollers 138 to abut against the coil. The power of the opening and closing linear mechanism 17 and the second material roller adjustment mechanism 136 to the second movable stop rollers 138 is transferred through the material roller connecting seat 18, so that the two second movable stop rollers 138 can be installed between the lifting feed table 14 and the unwinding drum 131 and will not interfere with the loading process after automatic control.

[0037] In addition, the opening and closing linear mechanism 17 and the lifting mechanism 15 are both operated synchronously through the power transmission mechanism 16. During the loading process, when the lifting feeding platform 14 moves upward to align the coil with the side of the unwinding drum 131, the two second movable stop rollers 138 are also moved below the coil by the power transmission mechanism 16. The unwinding drum 131 can then move to the lifting feeding platform 14 to obtain a new coil by the linear module 12. Since the second movable stop rollers 138 move with the unwinding body 13, in order to prevent the second movable stop rollers 138 from hitting the lifting feeding platform 14 or the lifting mechanism 15, the second material roller adjustment mechanism 136 synchronously drives the second movable stop rollers 138 to move towards the unwinding body 13 when the unwinding body 13 moves. The lifting feeding platform 14 is also set to extend towards the unwinding body 13, so that a space for the second movable stop rollers 138 can be placed below the extended part of the lifting feeding platform 14.

[0038] Therefore, by setting the uncoiling body 13 to be linearly movable, setting the lifting feed platform 14 to be lifting-only, and setting the material blocking device to be fixed and movable and distributed on both sides of the uncoiling drum 131, the uncoiling machine 10 can achieve fully automated feeding, automatic calibration of the discharge position, and more stable blocking and restriction on both sides of the material roll. This allows the uncoiling machine 10 to achieve more flexible operation and fully automated control, greatly reducing the geometric tolerance of the material output of the uncoiling machine 10, and improving the flexibility of the discharge position and the stability of the material roll fixation.

[0039] A material guiding device is connected to the feed end of the leveling machine 20. The material guiding device includes a frame 21 connected to the feed end of the leveling machine 20, an upper material guiding frame 22 rotatably connected to the frame 21, a lower material guiding frame 23 rotatably connected to the frame 21, a first cylinder 24 hinged to the frame 21 for rotating the upper material guiding frame 22, and a second cylinder 25 hinged to the frame 21 for rotating the lower material guiding frame 23. The upper material guiding frame 22 and the lower material guiding frame 23 open and close respectively through the push of the first cylinder 24 and the second cylinder 25. When the upper material guiding frame 22 and the lower material guiding frame 23 are open, it facilitates the entry of material into the leveling machine 20. 0. When the material enters the leveling machine 20, the upper feeder 22 and the lower feeder 23 are closed to better guide the material in. The lower feeder 23 is equipped with a middle plate 27 and corresponding side plates on both sides of the middle plate 27. The middle plate 27 is slidably connected to the lower feeder 23. The lower feeder 23 is also equipped with a pusher cylinder 26 for pushing the middle plate 27 to slide towards the uncoiler 10. By utilizing the cooperation between the middle plate 27 and the side plates, the middle plate slides towards the uncoiler 10 by being pushed by the pusher cylinder 26, thereby extending the length of the lower feeder 23 and enabling more flexible docking with the uncoiler 10.

[0040] A metalworking workshop integrating uncoiling, leveling, feeding, and fine blanking is provided based on the fine blanking process. A strip transfer machine 30 connects the leveling machine 20 and the fine blanking machine 40. The strip transfer machine 30 includes a lifting linear module 31 fixedly installed in the workshop, a transfer frame 32 powered by the lifting linear module 31, and transfer rollers 33 evenly arranged on the transfer frame 32. The transfer frame 32 is equipped with a transfer panel 331 and retaining walls 332 located on both sides of the transfer panel 331. The transfer rollers 33... The transition panel 331 is rotatably connected to the back of the transition panel 331, and an opening is provided on the transition panel 331 for the transition roller 33 to be exposed. The design of the strip transition machine 30 replaces the induction frame in the traditional design, which not only improves the automation performance of the whole machine, but also makes it faster to introduce the strip into the fine blanking feeder. The operation of the lifting linear module 31 is controlled by setting laser range measurement, and the transition frame is precisely raised and lowered according to the height of the strip when the leveler 20 is discharging, so that the leveler 20 and the fine blanking machine 40 are fully integrated to achieve fully automated and precise stamping, and the whole operation is smoother.

[0041] Please see Figure 7 In this embodiment, the power transmission mechanism 16 includes a cross steering gear 161 fixedly mounted on the base plate 11 and a braked servo motor 162. The braked servo motor 162 is poweredly connected to the cross steering gear 161.

The two first output ends are respectively driven to two opening and closing linear mechanisms 17, and the second output end is driven to the lifting mechanism 15. By using the cross steering gear 161 to connect to the braked servo motor 162, two mutually symmetrical first output ends and a second output end perpendicular to the first output ends are provided, so that the two opening and closing linear mechanisms 17 and the lifting mechanism 15 can be driven to run simultaneously. Its ingenious structural design achieves a compact and reasonable layout.

It has sufficient load-bearing capacity to lift the coil placed on the feeding platform 14. The feeding platform 14 is equipped with a lifting plate 141, a guide rod 142, an inclined guide seat 143 and a stop arm 144. The lifting plate 141 is guided and positioned by the guide rod 142. There are two symmetrical inclined guide seats 143, which can make the coil centered between the two inclined guide seats 143 after it is placed.

[0045] Please see Figure 5-8 In this embodiment, roller sleeves (not shown in the figure) are rotatably connected to the fixed stop roller 134, the first movable stop roller 137, and the second movable stop roller 138. The fixed stop roller 134, the first movable stop roller 137, and the second movable stop roller 138 all engage with the side of the coiled material mounted on the unwinding drum 131 via the roller sleeves, thereby limiting and protecting the coiled material loaded on the unwinding drum 131 and reducing wear between the material and the coil.
