Description

Technical Field

[0001] This application relates to the field of stamping technology, and more specifically, to a punch press feeding structure. Background Technology

[0002] For sheet metal workpieces, such as metal sheets and plates, stamping processes typically require forming and other operations at different locations on the workpiece.

[0003] In existing technologies, simple conveyor belts or robotic arms are typically used to feed small sheet metal workpieces. These workpieces are lightweight and easy to control, and generally only one forming operation is needed to produce a basic shape. However, for larger sheet metal workpieces that require multiple forming operations, the above feeding methods are not suitable. Due to the greater weight of large sheet metal workpieces, the conveyor belt or robotic arm cannot guarantee the stability of the workpiece during transport. When the conveyor belt or robotic arm moves the workpiece, it is prone to displacement, resulting in the inability to produce the predetermined number of workpieces for larger sheet metal workpieces, ultimately leading to material waste.

[0025] Reference Figure 1-4 , A punch press feeding structure includes: a punch press body 2, a fixed table 3, a feeding platform 4, a first conveying assembly 5, a second conveying assembly 6, and a fixed assembly 7. The punch press body 2 is provided with a stamping platform 21. One end of a sheet metal workpiece 1 is placed on the stamping platform 21, and the other end is placed on the feeding platform 4. The feeding platform 4 is slidably connected to the fixed table 3. The first conveying assembly 5 is used to drive the feeding platform 4 and the sheet metal workpiece 1 to move on the fixed table 3, so as to change the position of the sheet metal workpiece 1 on the stamping platform 21, so that the punch press body 2 can stamp at different positions on the sheet metal workpiece 1. The second conveying assembly 6 is disposed on the feeding platform 4, and the output end of the second conveying assembly 6 is used to push the sheet metal workpiece 1 towards the stamping platform 21. Specifically, the first conveying assembly 5 is used to drive the feeding platform 4 and the sheet metal workpiece 1 placed on the feeding platform 4 to move along the Y-axis, and the second conveying assembly 6 is used to push the sheet metal workpiece 1 to move along the X-axis. (See attached diagram for details.) Figure 1The fixing component 7 is located at the output end of the second conveying component 6, and is used to fix the plate-like workpiece 1 on the feeding platform 4. The sliding cooperation between the feeding platform 4 and the fixing table 3 provides stable support and guidance for the plate-like workpiece 1, ensuring the stability of the plate-like workpiece 1 during movement. The first conveying component 5 and the second conveying component 6 realize the adjustment of the processing position of the plate-like workpiece 1, meeting the needs of multiple pressing of the plate-like workpiece 1. The fixing component 7 can fix the plate-like workpiece 1 on the feeding platform 4, preventing the plate-like workpiece 1 from shifting in position on the feeding platform 4, so that a preset number of workpieces can be pressed out of the large-area plate-like workpiece 1, thereby reducing material waste.

[0026] Specifically, the punch press body 2 is provided with support components 8 on both sides; the support components 8 are provided with support surfaces 821 at the same height as the stamping platform 21; the support surfaces 821 are used to contact the sheet metal workpiece 1. Since the area of ​​the sheet metal workpiece 1 is much larger than the area of ​​the stamping platform 21, when the first conveying component 5 moves the feeding platform 4 and the sheet metal workpiece 1, the corners of the sheet metal workpiece 1 will droop towards the ground due to gravity, and a gap will be generated between the sheet metal workpiece 1 and the stamping platform 21. After the punch press body 2 punches the sheet metal workpiece 1, the edge of the workpiece will have a significant tilt angle, and such workpieces do not meet production standards. Therefore, support surfaces 821 are provided on both sides of the punch press body 2 to prevent the angle of the sheet metal workpiece 1 from drooping towards the ground, so that the punch press body 2 can press out workpieces that meet the standards.

[0027] Specifically, the feeding platform 4 is provided with positioning posts 41 on both sides; multiple positioning posts 41 are arranged along the pushing direction of the output end of the second conveying component 6; when the plate-like workpiece 1 is placed on the feeding platform 4, at least one end of the plate-like workpiece 1 is in contact with the positioning post 41. The positioning posts 41 are used to ensure that the plate-like workpiece 1 can be placed in the accurate position on the feeding platform 4, to prevent the plate-like workpiece 1 from being tilted on the feeding platform 4, and at the same time, the positioning posts 41 can also guide the plate-like workpiece 1 to move in a straight line on the feeding platform 4.

[0028] Specifically, the feeding platform 4 consists of a connecting seat 42 and square tubes 43; multiple square tubes 43 are arranged on the connecting seat 42, with a gap 431 formed between two adjacent square tubes 43; the connecting seat 42 is slidably connected to the fixed platform 3, and the multiple square tubes 43 are in contact with the plate-like workpiece 1. The arrangement of the square tubes 43 reduces the overall weight of the feeding platform 4 while ensuring that the feeding platform 4 has sufficient supporting strength.

[0029] Specifically, the first conveying assembly 5 includes a first lead screw 52 and a first motor 53; the fixed platform 3 is provided with slide rails 51, two of which are provided on the fixed platform 3; the connecting seat 42 has a groove on the side opposite to the square tube 43 that matches the slide rails 51; the first lead screw 52 is arranged along the length direction of the fixed platform 3 and is rotatably connected to the fixed platform 3; the first lead screw 52 is threadedly connected to the connecting seat 42; the first motor 53 is located at one end of the fixed platform 3 and connected to the first lead screw 52. The arrangement of the first lead screw 52 and the slide rails 51 enables the feeding platform 4 to move linearly in a fixed direction. When the first motor 53 stops working, the feeding platform 4 will be firmly stationed in the designated position and will not slide on the fixed platform 3 due to the vibration of the punch press body 2 during punching. In other embodiments, the first conveying assembly 5 is a first hydraulic cylinder; the output end of the first hydraulic cylinder is connected to the feeding platform 4, and the feeding platform 4 is slidably connected to the fixed platform 3.

[0030] Specifically, the second conveying assembly 6 includes: a sliding plate 61, a second lead screw 62, and a second motor 63. The second lead screw 62 is rotatably mounted on the connecting seat 42, and the sliding plate 61 is disposed on the side of the square tube 43 facing away from the plate-like workpiece 1, and the sliding plate 61 is threadedly connected to the second lead screw 62. Specifically, the connecting seat 42 has a square frame structure, and a sliding table is provided on the side of the connecting seat 42 facing the fixed platform 3. A sliding groove is provided on the sliding table, and the sliding table is slidably connected to the slide rail 51. An installation gap is provided between the sliding groove and the square tube 43, and the second lead screw 62 is disposed within the installation gap, with both ends of the second lead screw 62 rotatably connected to the connecting seat 42. The second motor 63 is fixedly mounted on the connecting seat 42, and the output end of the second motor 63 is connected to the second lead screw 62. The sliding plate 61 has an abutment portion 611, which is a plate-shaped structure. The abutment portion 611 extends through the gap 431 to the top of the square tube 43 and contacts the plate-like workpiece 1. The square tube 43 is used to guide the sliding plate 61 to prevent the sliding plate 61 from shifting its position during movement. In other embodiments, the second conveying component 6 is a second hydraulic cylinder, and the output end of the second hydraulic cylinder is provided with a push plate, which contacts the plate-like workpiece 1.

[0031] Specifically, the fixing component 7 includes a cylinder 71 and a pressure plate 72; the output end of the cylinder 71 is connected to the pressure plate 72, and the pressure plate 72 is used to contact the plate-like workpiece 1. The cylinder 71 is configured to make the distance between the pressure plate 72 and the square tube 43 adjustable to accommodate plate-like workpieces 1 of different thicknesses.

[0032] Specifically, at least two fixing components 7 are provided at the output end of the second conveying component 6 to prevent uneven force on a single point of the plate workpiece 1, which could lead to failure to press it tightly.

[0033] Specifically, the support assembly 8 includes a support frame 81 and driven rollers 82; multiple driven rollers 82 are arranged on the support frame 81, and the driven rollers 82 are rotatably connected to the support frame 81; the multiple driven rollers 82 form the support surface 821. In other embodiments, only support platforms are provided on both sides of the stamping platform 21. After the first conveying assembly 5 pushes the feeding platform 4 to move, friction will occur between the plate workpiece 1 and the support platform, which will cause scratches on the surface of the plate workpiece 1. In this embodiment, the setting of driven rollers 82 can reduce the contact area and friction with the plate workpiece 1, preventing scratches on the surface of the plate workpiece 1. At the same time, when the feeding platform 4 drives the plate workpiece 1 to move relative to the fixed table 3, the plate workpiece 1 will move on multiple driven rollers 82, and the driven rollers 82 rotate relative to the support frame 81, which can reduce the driving load of the first motor 53.
