Description

Technical Field

[0001] This utility model relates to the field of bending machine technology, and in particular to a double-sided positioning device for sheet metal processing using a bending machine. Background Technology

[0002] A bending machine is a device used to bend materials such as sheet metal and steel bars.

[0003] In the prior art, such as the positioning mechanism for a bending machine disclosed in Chinese Patent Publication No. CN219093412U, a worktable and a lower die of the bending machine are included. The lower die is located on the front side of the top of the worktable. A slide rail is provided on the worktable, symmetrically located on the left and right sides of the center of the worktable. An adjustment component is provided on the worktable. This positioning mechanism for a bending machine, through the provided adjustment component, can adjust the bending position of the sheet metal and also adjust the angle of the baffle, improving the practicality of the bending machine body to adapt to the positioning of sheet metal with non-straight end faces. This utility model relates to the field of bending machine technology, specifically providing a positioning mechanism for a bending machine.

[0004] However, existing bent parts require fixing at both ends during the bending process, necessitating the use of a double-sided positioning device. Due to varying lengths of the bent parts, the existing double-sided positioning device cannot adjust its position according to the length of the bent part. Furthermore, the bent part deforms during bending and needs to move, but it is fixed inside the positioning device and cannot move, thus reducing the bending effect. Therefore, these issues need to be addressed. Utility Model Content

[0005] The purpose of this invention is to provide a double-sided positioning device for sheet metal processing in bending machines, which has a good positioning effect on bent parts.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a double-sided positioning device for sheet metal processing in a bending machine, comprising a base plate, a mounting sleeve provided on the top of the base plate, an electric push rod fixedly installed inside the mounting sleeve, a connecting rod fixedly installed at the output end of the electric push rod, a slide rail fixedly connected to the edge of the top of the base plate, a pulley frame provided inside the slide rail, a pulley rotatably connected inside the pulley frame, the pulley slidably connected inside the slide rail, a positioning mechanism fixedly connected to the top of the pulley frame, a mounting plate fixedly connected to the outside of the positioning mechanism, a connecting rod fixedly connected to the center of the mounting plate, a first bolt threaded inside the mounting plate, a mounting block fixedly connected to the outside of the mounting sleeve, and a second bolt threaded inside the mounting block.

[0007] By adopting the above technical solution, the mounting sleeve is fixed at the top edge of the substrate, and then the second bolt is threaded into the inside of the mounting block, thereby fixing the mounting sleeve at the top edge of the substrate. Then, the electric push rod is installed inside the mounting sleeve. The positioning mechanism and the connecting rod are fixed together by the mounting plate and the first bolt, allowing the electric push rod to connect with the positioning mechanism. This operation not only achieves convenient connection but also provides excellent fixing. Furthermore, it allows for disassembly of the electric push rod and the positioning mechanism. There are two positioning mechanisms; the two electric push rods drive the two connecting rods to extend and retract, allowing the two positioning mechanisms to move. The two positioning mechanisms are supported by pulley frames and pulleys. When the two positioning mechanisms move, they move within the slide rail via the pulleys, improving the stability of their movement. The two ends of the bent piece are respectively installed inside the two positioning mechanisms, enabling positioning of both sides of the bent piece. The positions of the two positioning mechanisms can be adjusted according to the length of the bent piece, improving the positioning flexibility of the bent piece.

[0008] A further feature of this invention is that the number of the second bolts is two, and both of the second bolts are fitted with anti-slip pads.

[0009] By adopting the above technical solution, the anti-slip pad provides friction to prevent the second bolt from falling off.

[0010] A further feature of this invention is that the number of positioning mechanisms is two, and the two positioning mechanisms are distributed on both sides of the top of the slide rail.

[0011] By adopting the above technical solution and setting up two positioning mechanisms, the two ends of the bent part can be positioned.

[0012] A further feature of this invention is that the clamping plate of the positioning mechanism has a placement groove inside.

[0013] By adopting the above technical solution, when positioning the bent part, the bent part is placed into the notch inside the clamping plate.

[0014] A further feature of this invention is that cylinders are fixedly installed on both sides inside the clamping plate, and a roller frame is fixedly connected to the output end of the cylinders, with a roller rotatably connected inside the roller frame.

[0015] By adopting the above technical solution, the cylinder is activated, which drives the roller frame and roller to extend and retract.

[0016] A further feature of this invention is that a rubber layer is fixedly connected to the outside of the roller.

[0017] By adopting the above technical solution, the rubber layer is set on the outside of the roller and contacts the bending part, thereby clamping the bending part and fixing it inside the clamping plate. When the bending part is bent, it forms a bending arc and will move inside the clamping plate. Multiple rollers and the rubber layer clamp the bending part, and when the bending part moves, it will generate friction with the rubber layer. Multiple rollers are rotatably connected inside the roller frame, thereby causing the multiple rollers to rotate and achieve the purpose of moving the bending part.

[0018] A further feature of this invention is that the number of rollers is several, and the several rollers are grouped into groups of four.

[0019] By adopting the above technical solution, multiple rollers are divided into four groups, and the four groups of rollers are evenly distributed inside the two clamping plates.

[0020] A further feature of this invention is that cylinder frames are fixedly connected to both sides of the inner wall of the clamping plate, and the cylinders are fixedly installed inside the cylinder frames.

[0021] By adopting the above technical solution, the cylinder is fixed inside the clamping plate by the cylinder bracket, which improves the stability of the cylinder during operation.

[0022] A further feature of this invention is that mounting rails are fixedly connected to both sides of the bottom of the substrate.

[0023] By adopting the above technical solution, mounting rails are distributed on both sides of the bottom of the substrate, thereby enabling the substrate to be installed into the machine tool.

[0024] A further feature of this invention is that the number of electric push rods is two, and the two electric push rods are distributed on the left and right sides of the mounting sleeve.

[0025] By adopting the above technical solution, the output ends of the two electric push rods are connected to two connecting rods, which can then drive the two positioning mechanisms.

[0026] The beneficial effects of this utility model are:

[0027] 1. This utility model, through the arrangement of a base plate, mounting sleeve, electric push rod, connecting rod, slide rail, pulley frame, pulley, positioning mechanism, mounting plate, first bolt, mounting block, and second bolt, fixes the mounting sleeve to the top edge of the base plate. Then, the second bolt is threaded into the mounting block, thereby fixing the mounting sleeve to the top edge of the base plate. The electric push rod is then installed into the mounting sleeve. The positioning mechanism and connecting rod are fixed to each other via the mounting plate and the first bolt, allowing the electric push rod to connect with the positioning mechanism. This operation not only achieves convenient connection but also facilitates fixation. It offers excellent positioning performance and allows for the disassembly of the electric push rods and positioning mechanisms. Two positioning mechanisms are used, with two electric push rods driving two connecting rods to extend and retract, enabling the two positioning mechanisms to move. These mechanisms are supported by pulley frames and pulleys. During movement, the pulleys move within the slide rails, enhancing the stability of the positioning mechanism's movement. The two ends of the bent part are respectively installed inside the two positioning mechanisms, allowing for positioning of both sides of the bent part. Furthermore, the positions of the two positioning mechanisms can be adjusted according to the length of the bent part, improving the positioning flexibility of the bent part.

The bent part is placed into a notch inside the clamping plate, and the cylinder is activated, driving the roller frame and roller to extend and retract. The rubber layer is located on the outside of the roller and contacts the bent part, thus clamping it and fixing it inside the clamping plate. When the bent part is bent, it forms a bending arc and displaces within the clamping plate. Multiple rollers and the rubber layer clamp the bent part, and friction is generated between the bent part and the rubber layer during displacement. Multiple rollers are rotatably connected inside the roller frame, causing them to rotate and thus moving the bent part. Attached Figure Description

A second bolt 10 is threadedly connected inside the mounting block 11. Bolt 12 is used to fix the mounting sleeve 2 to the top edge of the base plate 1. Then, the second bolt 12 is threaded into the inside of the mounting block 11, thereby fixing the mounting sleeve 2 to the top edge of the base plate 1. Then, the electric push rod 3 is installed into the inside of the mounting sleeve 2. The positioning mechanism 8 and the connecting rod 4 are fixed to the first bolt 10 through the mounting plate 9, thereby allowing the electric push rod 3 to connect with the positioning mechanism 8. The above operation not only achieves the effect of convenient connection, but also facilitates good fixing effect. At the same time, it allows the electric push rod 3 and the positioning mechanism 8 to be disassembled. There are two positioning mechanisms 8. The two electric push rods 3 drive the two connecting rods 4 to extend and retract, thereby allowing the two positioning mechanisms 8 to move. The structure 8 is supported by pulley bracket 6 and pulley 7. When the two positioning mechanisms 8 are displaced, they are displaced inside the slide rail 5 by pulley 7, which improves the stability of the movement of the two positioning mechanisms 8. The two ends of the bent part are respectively installed inside the two positioning mechanisms 8, thereby enabling the positioning of both sides of the bent part. The positions of the two positioning mechanisms 8 can be adjusted according to the length of the bent part, improving the positioning flexibility of the bent part. There are two second bolts 12, and anti-slip pads are sleeved on the outside of the two second bolts 12. The anti-slip pads provide friction and prevent the second bolts 12 from falling off. There are two positioning mechanisms 8, which are distributed on both sides of the top of the slide rail 5. Through the setting of the two positioning mechanisms 8, the two ends of the bent part can be positioned. For positioning, the clamping plate 81 of the positioning mechanism 8 has a placement groove inside. When positioning the bent part, the bent part is placed into the notch inside the clamping plate 81. Cylinders 82 are fixedly installed on both sides inside the clamping plate 81. The output end of the cylinder 82 is fixedly connected to the roller frame 83. The roller frame 83 is rotatably connected to the inside of the roller 84. When the cylinder 82 is activated, it drives the roller frame 83 and the roller 84 to extend and retract. A rubber layer 85 is fixedly connected to the outside of the roller 84. The rubber layer 85 is located on the outside of the roller 84 and contacts the bent part, thereby clamping the bent part and fixing it inside the clamping plate 81. When the bent part is bent, it forms a bending arc.The bent part will be displaced inside the clamping plate 81. Multiple rollers 84 and a rubber layer 85 clamp the bent part, and friction will be generated between the bent part and the rubber layer 85 during displacement. The multiple rollers 84 are rotatably connected inside the roller frame 83, thereby causing the multiple rollers 84 to rotate and achieve the purpose of moving the bent part. There are several rollers 84, and the multiple rollers 84 are divided into four groups of four, and the four groups of rollers 84 are evenly distributed inside the two clamping plates 81. Cylinders are fixedly connected to both sides of the inner wall of the clamping plate 81. The cylinder 82 is fixedly installed inside the cylinder frame 86 and is secured to the inside of the clamping plate 81 via the cylinder frame 86, improving the stability of the cylinder 82 during operation.

Two electric push rods 3 are located on the left and right sides of the mounting sleeve 2, and their output ends are connected to two connecting rods 4, thus driving the two positioning mechanisms 8.

[0037] In this invention, the mounting sleeve 2 is fixed to the top edge of the base plate 1. Then, the second bolt 12 is threaded into the mounting block 11, thus fixing the mounting sleeve 2 to the top edge of the base plate 1. Next, the electric push rod 3 is installed inside the mounting sleeve 2. The positioning mechanism 8 and the connecting rod 4 are fixed together by the mounting plate 9 and the first bolt 10, allowing the electric push rod 3 to connect with the positioning mechanism 8. This operation not only achieves convenient connection but also provides excellent fixing. Furthermore, it allows for disassembly of the electric push rod 3 and the positioning mechanism 8. There are two positioning mechanisms 8; the two electric push rods 3 drive the two connecting rods 4 to extend and retract, allowing the two positioning mechanisms 8 to move. The two positioning mechanisms 8 are supported by a pulley frame 6 and pulleys 7. When the two positioning mechanisms 8 move, they move within the slide rail 5 via the pulleys 7, improving the stability of their movement and separating the two ends of the bent part. The bending part is installed inside the two positioning mechanisms 8, which can position both sides of the bending part and adjust the position of the two positioning mechanisms 8 according to the length of the bending part, thereby improving the positioning flexibility of the bending part. When positioning the bending part, the bending part is placed into the notch inside the clamping plate 81, and the cylinder 82 is activated, which drives the roller frame 83 and the roller 84 to extend and retract. The rubber layer 85 is set on the outside of the roller 84 and contacts the bending part, thereby clamping the bending part and fixing it inside the clamping plate 81. When the bending part is bent, it forms a bending arc and will move inside the clamping plate 81.
