Description

Technical Field

[0001] This utility model relates to the field of flying shear machine technology, specifically to an end plate device for a stacking table. Background Technology

[0002] During the adjustment of the end plate position on the flying shear machine, if the end plate on the base does not reach the forward limit (proximity switch), it will continue to move forward if the operation of the end plate continues. Normally, the end plate should stop immediately after hitting the wooden support (used to support the aluminum plate). However, it is difficult to see the actual distance between the end plate and the wooden support during on-site operation. Furthermore, the end plate continues to move forward after hitting the wooden support. Due to the obstruction of the wooden support, the end plate compresses the spring on the base backward. When the spring reaches its limit, the end plate will hit the cylinder shaft and damage the cylinder. Therefore, if the end plate moves forward excessively, it will hit the cylinder shaft and damage the cylinder. Therefore, there is an urgent need for an end plate device for stacking platforms to solve the above problems. Utility Model Content

[0003] To address the technical problem of the end plate on a flying shear machine accidentally hitting the cylinder shaft and damaging it when it advances too far, this invention provides an end plate device for a stacking platform. Once the end plate contacts the wooden support, the wooden support's blocking and cushioning structure causes the end plate to move to a proximity switch position and activate it, stopping the end plate's movement and preventing it from hitting the cylinder shaft, thus effectively improving the cylinder's service life.

[0004] This utility model provides an end plate device for a stacking platform. The end plate device is located above the stacking platform and includes a base and an end plate. The base is slidably mounted on the working ground. A cylinder and a proximity switch are provided on the base. The telescopic rod of the cylinder is connected to the end plate and can drive it to slide. A buffer structure is provided between the base and the end plate. The proximity switch is located between the cylinder shaft and the end plate.

[0005] Furthermore, the buffer structure includes a movable shaft and a spring. A hollow sleeve is provided on the base, and the movable shaft passes through the hollow sleeve and can slide on it. One end of the movable shaft is fixedly connected to an end plate, and the other end of the movable shaft is fixedly connected to a plug. The spring is sleeved on the movable shaft, with one end of the spring fixedly connected to the movable shaft and the other end of the spring fixedly connected to the end plate. When the cylinder drives the end plate to slide, the movable shaft slides on the hollow sleeve, resulting in higher stability of the end plate sliding.

[0006] Furthermore, two buffer structures and two hollow sleeves are provided. This further improves the stability of the end plate during sliding.

[0007] Furthermore, a frame is provided on the working surface, a guide rail is provided on the frame, a guide block is slidably disposed within the guide rail, a lead screw is rotatably disposed on the frame, and a nut seat is threadedly connected to the lead screw. One side of the nut seat is fixedly connected to the guide block, and the other side of the nut seat is fixedly connected to the seat body. Rotation of the lead screw will cause the nut seat to slide left and right relative to the lead screw, thereby causing the guide block to slide left and right within the guide rail, and also causing the seat body to slide left and right.

[0008] Furthermore, the frame is equipped with a servo motor and two bearing seats. The two ends of the lead screw are rotatably connected to the two bearing seats. The output shaft of the servo motor is fixedly connected to the end of the lead screw and can drive it to rotate. When the servo motor starts, it drives the lead screw to rotate. The rotation of the lead screw causes the nut seat to slide left and right relative to the lead screw, which in turn causes the guide block to slide left and right within the guide rail, and also causes the seat to slide left and right.

[0009] Furthermore, an L-shaped support plate is provided on the base, and a through hole is provided on the L-shaped support plate. The through hole is located between the cylinder shaft and the end plate, and the proximity switch is fixedly connected to the through hole by a nut. The proximity switch is fixed between the cylinder shaft and the end plate by the nut and the through hole on the base.

[0010] Furthermore, a flexible plate is provided on the side of the end plate away from the cylinder, and the flexible plate is used to contact the aluminum plate. In fact, the flexible plate makes contact with the aluminum plate, and the flexible plate avoids damaging the aluminum plate and causing a loss of its quality.

[0011] Compared with the prior art, the present invention has the following technical effects:

[0012] Once the end plate comes into contact with the wooden support, the end plate will press against the buffer structure (to the left) due to the obstruction of the wooden support. At this time, the end plate will first move to the position of the proximity switch and activate the proximity switch (the proximity switch senses the end plate). The buffer structure has not yet reached its limit. At this time, the base, end plate and cylinder will stop sliding (to the right). The wooden support will no longer press against the end plate (to the left). The end plate will then stop moving, thus avoiding the end plate hitting the cylinder shaft head, thereby reducing the downtime of the flying shear machine. Attached Figure Description

[0018] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0019] like Figures 1-3 As shown, an end plate device for a stacking platform is located above a stacking platform 8. The end plate device includes a base 1 and an end plate 2. The base 1 is slidably mounted on the working surface. A cylinder 3 and a proximity switch 4 are mounted on the base 1. The telescopic rod of the cylinder 3 is connected to the end plate 2 and can drive it to slide. A buffer structure is provided between the base 1 and the end plate 2. The proximity switch 4 is located between the shaft of the cylinder 3 and the end plate 2. Generally, the telescopic rod of the cylinder 3 extends and retracts after passing through the shaft of the cylinder 3. When in use, the end plate device is used in conjunction with the stacking platform 8 on a flying shear machine. The structure of the stacking platform 8 is existing technology and will not be described in detail here. The stacking platform 8 can be raised and lowered and is located below the end plate device. Generally, a wooden support 9 is placed on the stacking platform 8. When the stacking platform 8 is raised and lowered, it drives the wooden support 9 to rise and fall, and aluminum plates are stacked on the wooden support 9.

[0020] To ensure the aluminum plates stacked on the wooden support 9 remain consistent, an end plate device is used. A fixed plate 81 is located on the stacking platform 8. The end plate device adjusts its position according to the size of the aluminum plates, ensuring that after the aluminum plates are stacked on the wooden support 9, multiple aluminum plates are positioned between the end plate device and the fixed plate 81, thus maintaining consistency. Specifically, depending on the position of the wooden support 9, when the base 1 slides (to the right), it causes the end plate 2 and cylinder 3 to slide together (to the right) and approach the wooden support 9. Then, depending on the size of the aluminum plates, cylinder 3 activates, causing end plate 2 to slide again (to the right), pressing against the aluminum plate and fixing it between end plate 2 and fixed plate 81. At this time, the buffer structure is in an extended state. Generally, as the aluminum plates are stacked on the wooden support 9, the stacking platform 8 lowers the wooden support 9 and the aluminum plates. After all the aluminum plates are stacked, cylinder 3 causes end plate 2 to slide again (to the left), at which point the buffer structure is in a retracted state.

[0021] When working with aluminum plates of different sizes, the end plate device needs to be adjusted. When adjustment is required, the positions of the wooden support 9 and the stacking platform 8 may not be properly adjusted. As the base 1 slides together with the end plate 2 and cylinder 3 (to the right), if the end plate 2 comes into contact with the wooden support 9, the wooden support 9 will cause the end plate 2 to press against the buffer structure (to the left). At this point, the end plate 2 will move to the position of the proximity switch 4 and activate it (the proximity switch 4 senses the end plate 2). Before the buffer structure reaches its limit, the base 1, end plate 2, and cylinder 3 will stop sliding (to the right), and the wooden support 9 will no longer press against the end plate 2 (to the left). The end plate 2 will then stop moving, thus preventing it from hitting the cylinder 3's shaft. Furthermore, when the end plate 2 does hit the wooden support 9, the buffer structure reduces the impact force, providing a cushioning effect.

[0022] The end plate device in this embodiment has a simple structure and is easy to operate. Once the end plate 2 comes into contact with the wooden support 9, the end plate 2 will press the buffer structure (to the left) due to the obstruction of the wooden support 9. At this time, the end plate 2 will first move to the position of the proximity switch 4 and activate the proximity switch 4 (the proximity switch 4 senses the end plate 2). The buffer structure has not yet reached its limit. At this time, the seat 1, the end plate 2 and the cylinder 3 will stop sliding (to the right). The wooden support 9 will no longer press the end plate 2 (to the left). The end plate 2 will then stop moving, thereby avoiding the end plate 2 from hitting the shaft of the cylinder 3, effectively improving the service life of the cylinder 3, and thus reducing the downtime of the flying shear machine.

[0023] In one possible implementation, the buffer structure includes a movable shaft 5 and a spring 6. A hollow sleeve 11 is provided on the base 1. The movable shaft 5 passes through the hollow sleeve 11 and can slide on it. One end of the movable shaft 5 is fixedly connected to the end plate 2, and the other end of the movable shaft 5 is fixedly connected to a plug 51. The spring 6 is sleeved on the movable shaft 5, with one end fixedly connected to the movable shaft 5 and the other end fixedly connected to the end plate 2. When the cylinder 3 drives the end plate 2 to slide, the movable shaft 5 slides on the hollow sleeve 11, resulting in higher stability of the end plate 2's sliding motion. The plug 51 prevents the movable shaft 5 from sliding out of the hollow sleeve 11.

[0024] When the seat 1 slides together with the end plate 2 and the cylinder 3 (to the right), once the end plate 2 comes into contact with the wooden support 9, the end plate 2 will squeeze the spring 6 (to the left) due to the obstruction of the wooden support 9, and the movable shaft 5 and the end plate 2 will slide (to the left). At this time, the end plate 2 will first move to the position of the proximity switch 4 and activate the proximity switch 4 (the proximity switch 4 senses the end plate 2). The spring 6 has not yet reached its limit. At this time, the seat 1, the end plate 2 and the cylinder 3 will stop sliding (to the right), and the wooden support 9 will no longer squeeze the end plate 2 (to the left). The end plate 2 will then stop moving, thereby avoiding the end plate 2 from hitting the shaft of the cylinder 3.

[0025] As one possible implementation, two buffer structures and two hollow sleeves 11 are provided. This further improves the stability of the end plate 2 during sliding.

[0026] In one possible implementation, a frame 7 is provided on the working surface, a guide rail 71 is provided on the frame 7, a guide block 72 is slidably disposed within the guide rail 71, a lead screw 73 is rotatably disposed on the frame 7, and a nut seat 74 is threadedly connected to the lead screw 73. One side of the nut seat 74 is fixedly connected to the guide block 72, and the other side of the nut seat 74 is fixedly connected to the base 1. Rotation of the lead screw 73 will cause the nut seat 74 to slide left and right relative to the lead screw 73, thereby causing the guide block 72 to slide left and right within the guide rail 71, and also causing the base 1 to slide left and right.

[0027] In one possible implementation, the frame 7 is equipped with a servo motor 76 and two bearing seats 75. The two ends of the lead screw 73 are rotatably connected to the two bearing seats 75, and the two ends of the lead screw 73 are fixedly connected to the bearings in the two bearing seats 75. The output shaft of the servo motor 76 is fixedly connected to the end of the lead screw 73 and can drive it to rotate. When the servo motor 76 starts, it drives the lead screw 73 to rotate. The rotation of the lead screw 73 causes the nut seat 74 to slide left and right relative to the lead screw 73, which in turn causes the guide block 72 to slide left and right within the guide rail 71, and also causes the seat 1 to slide left and right.

[0028] In one possible implementation, an L-shaped support plate 12 is provided on the base 1. The L-shaped support plate 12 can be fixed to the base 1 by welding. The L-shaped support plate 12 has a through hole located between the shaft head of the cylinder 3 and the end plate 2. The proximity switch 4 is fixedly connected to the through hole by a nut. In this embodiment, the proximity switch 4 is model LJA18M-10D1. The proximity switch 4 is fixed between the shaft head of the cylinder 3 and the end plate 2 by the nut and the through hole on the base 1.

[0029] In one possible implementation, a flexible plate 21 is provided on the side of the end plate 2 away from the cylinder 3. The flexible plate 21 is used to contact the aluminum plate. The end plate 2 abuts against the aluminum plate and fixes the aluminum plate between the end plate 2 and the fixing plate 81. In fact, the flexible plate 21 is in contact with the aluminum plate, and the flexible plate 21 avoids damaging the aluminum plate and causing a loss of aluminum plate quality. The flexible plate 21 can be made of flexible materials such as PVC.

[0030] The embodiments described above are merely preferred embodiments of this utility model and are only used to explain this utility model. They are not intended to limit the scope of implementation of this utility model. For those skilled in the art, other implementation methods can be easily made by substitution or modification based on the technical content disclosed in this specification. Therefore, all changes and improvements made to the principles and process conditions of this utility model should be included within the scope of the patent application of this utility model.
