Description

Technical Field

[0001] The utility model belongs to the technical field of the material stop device of a bending machine, and particularly relates to the material stop device of a bending machine on the bending machine. Background Technique

[0002] The essence of a numerical control bending machine is a numerical control bending machine die for bending steel plates. The die is composed of a bracket, a workbench and a clamping plate. By energizing a coil to generate an attraction force on the pressure plate, the clamping of the thin plate between the pressure plate and the base is completed. The plate is placed in the horizontal direction, and a material stop device is provided to limit the position of the horizontally moved material, so as to facilitate the accuracy of the bending position.

[0003] The existing material stop device blocks and limits the sheet material. When the sheet material is bent, the side of the sheet material in contact with the material stop device rubs against the material stop device. Prolonged use causes damage, resulting in errors when limiting the subsequent sheet materials. Content of the Utility Model

[0004] Aiming at the deficiencies of the prior art, the purpose of the utility model is to provide a material stop device of a bending machine on the bending machine. When the workpiece is bent, it can prevent the side of the workpiece from warping and rubbing against the baffle, avoid causing wear of the baffle, and reduce the error caused when limiting the subsequent workpiece.

[0005] The purpose of the utility model can be realized by the following technical solutions:

[0006] The material stop device of a bending machine on the bending machine includes:

[0007] A baffle, at the upper and lower ends of one side surface of the baffle, support plates are fixedly connected. Between the two support plates, two clamping plates are arranged. On each clamping plate, a screw rod is rotatably connected. The other end of the screw rod passes through the support plate and is threadedly connected with the support plate. At the two ends of the other side surface of the baffle, guide columns are fixedly connected. A moving block is slidably connected to the guide columns. A first limiting hole is opened on the moving block. A spring is sleeved on the guide columns.

[0008] Linear guide rails, two groups of linear guide rails are arranged vertically. A slider is slidably connected to the linear guide rails. A connecting block is fixedly connected to the slider. A second limiting hole is opened on the connecting block. The side end of the connecting block is rotatably connected to the side surface of the moving block.

[0009] A limiting pin, the limiting pin is inserted into the first limiting hole and the first limiting hole. A connecting plate is fixedly connected to the outer side end of the limiting pin. A bolt is threadedly connected to the connecting plate. The bolt is rotatably connected to the moving block.

[0010] The above technical solution, its principle and technical effect:

[0011] At this time, the slider is located at the lowest end of the linear guide rail, and the baffle is in a vertical state. The spring is arranged so that the baffle fits the moving block in its natural state. When the workpiece is inserted between the two clamping plates, the screw is rotated to make the two clamping plates move towards each other to clamp the workpiece. At this time, the bolt is rotated to drive the limit pin out of the second limit hole. When the workpiece is bent, the side of the workpiece will tilt upwards. At this time, the baffle will move upwards along the linear guide rail following the tilt of the workpiece. During the movement, the baffle tilts from the vertical state. At this time, deflection occurs between the moving block and the connecting block. At the same time, the baffle will move away from the moving block. At this time, the guide post slides with the moving block. A series of actions are all to make the baffle adapt to the self-adaptive adjustment of the state when the workpiece tilts, avoid large stress at the part where the workpiece is connected to the clamping plate, and avoid workpiece deformation. This device avoids frictional loss between the workpiece and the baffle.

[0012] Further, limit posts are fixedly connected to both ends of the clamping plate. The limit posts pass through the support plate and are slidably connected to the support plate.

[0013] Further, a first stop block is fixedly connected to the end of the limit post away from the clamping plate.

[0014] Further, a rotating member is fixedly connected to the end of the screw away from the clamping plate.

[0015] Further, a second stop block is fixedly connected to the end of the guide post away from the baffle. The spring is sleeved on the guide post between the moving block and the second stop block.

[0016] Further, the inner diameters of the first limit hole and the second limit hole are the same.

[0017] Further, a connection hole is formed in the connecting block. A connection shaft is fixedly connected to the side surface of the moving block. The connection shaft is rotatably connected in the connection hole.

[0018] Further, a fixed seat is fixedly connected between the two groups of linear guide rails.

[0019] The explanations of the nouns, conjunctions or adjectives involved in the above technical solutions are as follows:

[0020] Fixed connection means that after the parts or components are fixed, there is no relative movement connection. It is divided into two types: detachable connection and non-detachable connection.

[0021] (1) Detachable connection uses screws, splines, wedge pins, etc. to fix the parts together. This connection method can be disassembled during maintenance and will not damage the parts. However, the specifications of the connecting parts used must be correct (such as the length of bolts, keys, wedge pins), and they must be tightened appropriately.

[0022] (2) Non-detachable connections mainly refer to welding, riveting, and mortise fitting, etc. Since forging, sawing, or oxygen cutting is required for disassembly during maintenance or replacement, spare parts generally cannot be reused. At the same time, during connection, attention should be paid to process quality, technical inspection, and remedial measures (such as correction, polishing, etc.).

[0023] Threaded connection refers to a detachable connection that connects the connected parts into one body with threaded parts (or the threaded parts of the connected parts).

[0024] Sliding connection means that two objects are in contact but not fixed, and they can slide relative to each other.

[0025] Rotational connection means that the connection between parts allows the parts to rotate relative to each other.

[0026] Advantages of the present utility model:

[0027] When the workpiece is bent, it can avoid the side of the workpiece from warping and rubbing against the baffle, avoid causing wear of the baffle, and reduce the error caused when limiting the subsequent workpiece. Description of the drawings

Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of them.

[0034] According to the concept of the present application, embodiments of the bending machine stop device on the bending machine are described herein in conjunction with Figures 1 to 3 Specifically, the bending machine stop device on the bending machine is configured as a split structure, which has components such as a baffle 1, a linear guide rail 9, a limit pin 13, etc. Through the mutual cooperation of structures such as the clamping plate 3, the guide post 5, the moving block 6, and the slider 10, at this time, the slider 10 is located at the lowermost end of the linear guide rail 9, the baffle 1 is in a vertical state, and the setting of the spring 8 makes the baffle 1 fit the moving block 6 in the natural state. When the workpiece is inserted between the two clamping plates 3, the screw 4 is rotated to make the two clamping plates 3 move towards each other to clamp the workpiece. At this time, the bolt 22 is rotated to drive the limit pin 13 to disengage from the second limit hole 12. When the workpiece is bent, the side of the workpiece will tilt upwards. At this time, the baffle 1 will move upwards along the linear guide rail 9 following the tilt of the workpiece. During the movement, the baffle 1 tilts from the vertical state. At this time, deflection occurs between the moving block 6 and the connecting block 11. At the same time, the baffle 1 will move away from the moving block 6. At this time, the guide post 5 slides with the moving block 6. A series of actions are all to enable the baffle 1 to adapt to the self-adaptive adjustment of the state when the workpiece tilts, avoid large stress at the part where the workpiece is connected to the clamping plate 3, avoid workpiece deformation, and this device avoids frictional loss between the workpiece and the baffle 1.

[0035] As Figures 1 - 3 shown, the bending machine stop device on the bending machine includes:

[0036] A baffle 1, with support plates 2 fixedly connected to both the upper and lower ends of one side surface of the baffle 1. Between the two support plates 2, two clamping plates 3 are provided. A screw 4 is rotatably connected to each clamping plate 3, and the other end of the screw 4 passes through the support plate 2 and is threadedly connected to the support plate 2. At both ends of the other side surface of the baffle 1, guide posts 5 are fixedly connected. A moving block 6 is slidably connected to the guide posts 5. A first limit hole 7 is formed in the moving block 6, and a spring 8 is sleeved on the guide posts 5;

[0037] Two sets of linear guide rails 9 are arranged vertically. A slider 10 is slidably connected to the linear guide rails 9. A connecting block 11 is fixedly connected to the slider 10.

[0038] The limit pin 13 is inserted into the first limit hole 7 and the second limit hole 12. A connecting plate 14 is fixedly connected to the outer side end of the limit pin 13. A bolt 22 is threadedly connected to the connecting plate 14, and the bolt 22 is rotatably connected to the moving block 6.

[0039] During use, at this time, the slider 10 is located at the lowermost end of the linear guide 9, the baffle 1 is in a vertical state. The setting of the spring 8 makes the baffle 1 fit the moving block 6 in the natural state. When the workpiece is inserted between the two clamping plates 3, rotate the screw rod 4 to make the two clamping plates 3 move towards each other to clamp the workpiece. At this time, rotate the bolt 22 to drive the limit pin 13 out of the second limit hole 12. When the workpiece is bent, the side of the workpiece will tilt upwards. At this time, the baffle 1 will move upwards along the linear guide 9 following the tilt of the workpiece. During the movement, the baffle 1 tilts from the vertical state. At this time, a deflection occurs between the moving block 6 and the connecting block 11. At the same time, the baffle 1 will move away from the moving block 6. At this time, the guide post 5 slides with the moving block 6. A series of actions are all to make the baffle 1 adapt to the self-adaptive adjustment of the state when the workpiece tilts, avoid a large stress at the part where the workpiece is connected to the clamping plate 3, and avoid the deformation of the workpiece. This device avoids the frictional loss between the workpiece and the baffle 1.

[0041] In an embodiment of the present utility model, a first stop block 16 is fixedly connected to the end of the limit post 15 far from the clamping plate 3. This prevents the limit post 15 from detaching from the support plate 2.

[0042] In an embodiment of the present utility model, a rotating member 17 is fixedly connected to the end of the screw rod 4 far from the clamping plate 3. This facilitates the rotation of the screw rod 4.

[0043] In an embodiment of the present utility model, a second stop block 18 is fixedly connected to the end of the guide post 5 far from the baffle 1. The spring 8 is sleeved on the guide post 5 between the moving block 6 and the second stop block 18. The setting of the second stop block 18 prevents the guide post 5 from detaching from the moving block 6 and prevents the spring 8 from detaching from the guide post 5.

[0044] In an embodiment of the present utility model, the inner diameters of the first limit hole 7 and the second limit hole 12 are the same.
