Description

Technical Field

[0001] This utility model relates to the field of tool changing technology, specifically a tool changing device for cold rolling longitudinal cutting of steel. Background Technology

[0002] The tool changing device for cold rolling slitting of steel is a piece of equipment used in the cold rolling steel plate slitting production line. During the cold rolling steel plate slitting process, the tools need to be replaced due to wear and other reasons. The tool changing device is a device specifically designed to complete the tool changing task efficiently and accurately. Its main components consist of a tool changing assembly and a tool storage assembly.

[0003] The tool changing assembly mainly consists of a handling robot and a clamping assembly. The robot moves the clamping assembly to the longitudinal cutting axis, where it clamps the tool to be changed and removes it from the longitudinal cutting axis. The clamped tool is then transported to the tool storage assembly for storage. When using a robot and clamping assembly to change and transport tools, the robot needs to transport the tool to the tool storage location one tool at a time. The robot needs to make multiple round trips to perform the same transport task, which is not convenient for transporting the tool to be changed at the same time, thus prolonging the tool changing time. At the same time, when using the clamping method to transfer tools, the clamping assembly is prone to scratching the tool surface when clamping the tool. In view of the shortcomings of the existing technology, we propose a tool changing device for cold rolling longitudinal cutting of steel to solve the above problems. Utility Model Content

The conveying assembly includes a mechanical support arm, a conveying shaft, a pushing unit, and a limiting assembly. The mechanical support arm is laterally slidably connected to the top of the support base, and the conveying shaft is vertically slidably connected to the outer wall of the mechanical support arm. The pushing unit and the limiting assembly are both located at the conveying shaft. The pushing unit pushes the tool to be sleeved on the outer peripheral wall of the conveying shaft, and the limiting assembly limits and fixes the tool at the conveying shaft.

[0005] The pushing unit consists of a first pushing component, a second pushing component, and a pushing plate. The first pushing component and the second pushing component are located at the top and bottom of the conveying shaft, respectively, and the pushing plate is installed at one end of the pushing plate.

[0006] Preferably, a drive disk is fixedly connected to the bottom of the mechanical support arm, a mounting base is fixedly connected to the top of the support base, the drive disk is rotatably connected to the top of the mounting base, a drive plate is slidably connected to the outer wall of the mechanical support arm, and a fixing plate is fixedly connected to the outer wall of the drive plate.

[0007] Preferably, the limiting component includes a disc, an electromagnet, and a third cylinder, wherein the third cylinder is fixedly installed on the outer wall of the fixed plate.

[0008] Preferably, the output end of the third cylinder is fixedly connected to the disc, and the electromagnet and the conveying shaft are both fixedly installed on the outer wall of the disc.

[0009] Preferably, the first pushing component and the second pushing component are composed of the same components, and the pushing component includes a U-shaped plate, a first cylinder, a second cylinder, a connecting plate, and a mounting component.

[0010] Preferably, the U-shaped plates are fixedly installed at the top and bottom of the fixed plate, the first cylinder is fixedly installed at the top of the U-shaped plate, and the second cylinder is installed inside the U-shaped plate.

[0013] This utility model discloses a tool changing device for cold rolling slitting of steel, which has the following beneficial effects: The tool changing device for cold rolling slitting of steel, by comprising a conveying component consisting of a mechanical support arm, a conveying shaft, a pushing unit and a limiting component, can sequentially push multiple sets of tools at the slitting shaft to the outer peripheral wall of the conveying shaft. The conveying shaft supports the multiple sets of tools, thereby facilitating the one-time delivery of multiple sets of tools to the tool storage shaft. Compared with tool changing using a robotic arm, when the robotic arm delivers the tools to the tool storage location one by one, the robotic arm needs to perform the same delivery task multiple times. By delivering multiple sets of tools at once, the number of times the robotic arm has to go back and forth is reduced, thereby improving the efficiency of tool changing. At the same time, the pushing method can reduce tool wear and further protect the tools. Attached Figure Description

[0022] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments of this utility model are described clearly and completely. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0023] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0024] This utility model discloses a tool changing device for longitudinal cutting of cold rolled steel.

[0025] According to the appendix Figure 1-6As shown, the system includes a support base 1, with a support side plate 101 fixedly connected to one side of the top of the support base 1. Multiple sets of tool storage shafts 2 are arranged on the inner wall of the support side plate 101. A conveying assembly is arranged on one side of each tool storage shaft 2. The conveying assembly includes a mechanical support arm 3, a conveying shaft 4, a pushing unit 5, and a limiting component 6. The mechanical support arm 3 is laterally slidably connected to the top of the support base 1, and the conveying shaft 4 is vertically slidably connected to the outer wall of the mechanical support arm 3. The pushing unit 5 and the limiting component 6 are both located at the conveying shaft 4. The pushing unit 5 pushes the tool to fit onto the outer peripheral wall of the conveying shaft 4, and the limiting component 6 limits and fixes the tool at the conveying shaft 4. Before replacing the tool on the longitudinal cutting shaft, two sets of pushing plates 503 are located on both sides of the conveying shaft 4, with the front end of the conveying shaft 4 facing outwards. See the attached diagram for details. Figure 1 .

[0026] The pushing unit 5 consists of a first pushing component 501, a second pushing component 502, and a pushing plate 503. The first pushing component 501 and the second pushing component 502 are located at the top and bottom of the transport shaft 4, respectively. The pushing plate 503 is installed at one end of each pushing plate 503. When changing the cutters on the two sets of longitudinal cutting shafts, firstly, one end of the transport shaft 4 is moved to one end of the longitudinal cutting shaft so that the transport shaft 4 is aligned with the longitudinal cutting shaft. Then, the two pushing components are activated to push the cutters at the two sets of longitudinal cutting shafts. The conveyor shaft 4 is sleeved on the outer peripheral wall and then rotatably connected to the top of the mounting base 301 via the drive plate 302 at the bottom of the mechanical support arm 3, so that the front end of the conveyor shaft 4 faces inward. With the cooperation of the mechanical support arm 3 and the drive plate 303, the conveyor shaft 4 can be driven to move accurately to the tool storage shaft 2. With the cooperation of the pusher assembly, multiple sets of tools can be pushed to the outer peripheral wall of the tool storage shaft 2 for collection. Then, new tools are installed one group at a time at the longitudinal cutting shaft, realizing the tool replacement work.

[0027] A drive plate 302 is fixedly connected to the bottom of the mechanical support arm 3, and a mounting base 301 is fixedly connected to the top of the support base 1. The drive plate 302 is rotatably connected to the top of the mounting base 301. A drive plate 303 is slidably connected to the outer wall of the mechanical support arm 3, and a fixing plate 304 is fixedly connected to the outer wall of the drive plate 303. First, the third cylinder 603 and the second cylinder 5033 at the first pushing assembly 501 are started, respectively driving the conveying shaft 4 and the pushing plate 503 to move laterally, so that one end of the conveying shaft 4 is in contact with one end of the longitudinal cutting shaft. Then, the second cylinder 5033 works, continuing to drive the pushing plate 503 to move laterally, so that the pushing plate 503 is located at the bottom of the outer wall of the longitudinal cutting blade. For details, please refer to the appendix. Figure 3Then, by activating the first cylinder 5032, the pusher plate 503 is moved upward, positioning itself on the outer wall of the tool. Finally, the second cylinder 5033 retracts the pusher plate 503, allowing it to push the tool to the outer wall of the transport shaft 4. The electromagnet 602 is then energized, magnetically securing the tool. Following this process, multiple sets of tools at the bottom longitudinal cutting blade are sequentially pushed to the outer wall of the transport shaft 4. The transport shaft 4 then sequentially transports these multiple sets of tools to the outer wall of the tool storage shaft 2 for storage, facilitating later maintenance of the replaced tools. When transporting and replacing the tool at the top longitudinal cutting shaft, the second pusher assembly 502 is activated. Working on the same principle as the first pusher assembly 501, it pushes multiple sets of tools to the transport shaft 4 and simultaneously transports multiple sets of replaced tools, reducing the time required for tool replacement and thus improving the overall efficiency of tool replacement.

[0028] The limiting component 6 includes a disc 601, an electromagnet 602, and a third cylinder 603. The third cylinder 603 is fixedly installed on the outer wall of the fixed plate 304. The output end of the third cylinder 603 is fixedly connected to the disc 601. The electromagnet 602 and the conveying shaft 4 are both fixedly installed on the outer wall of the disc 601. By sliding the drive plate 303 vertically on the outer wall of the mechanical support arm 3 and sliding the mechanical support arm 3 laterally on the top of the support base 1, the conveying shaft 4 can be accurately moved to one side of the multiple tool storage shaft 2, and the multiple sets of tools are pushed to the tool storage shaft 2 for storage in sequence.

[0029] The first pushing assembly 501 and the second pushing assembly 502 are composed of the same components. The pushing assembly includes a U-shaped plate 5031, a first cylinder 5032, a second cylinder 5033, a connecting plate 5034, and a mounting component 5035. The U-shaped plate 5031 is fixedly installed on the top and bottom of the fixed plate 304, the first cylinder 5032 is fixedly installed on the top of the U-shaped plate 5031, and the second cylinder 5033 is installed inside the U-shaped plate 5031. It should be noted that by rotating the drive disk 302 at the bottom of the mechanical support arm 3 to the top of the mounting base 301, one end of the opening of the conveying shaft 4 can be rotated to the side of the tool storage shaft 2, which facilitates pushing the tool at the conveying shaft 4 to the tool storage shaft 2 for tool storage.

[0030] The output end of the first cylinder 5032 is fixedly connected to the outer wall of the second cylinder 5033, the output end of the second cylinder 5033 is fixedly connected to the connecting plate 5034, the mounting part 5035 is fixedly installed on the top of the pusher plate 503 and fixedly connected, and one end of the mounting part 5035 is fixedly connected to the connecting plate 5034.
