Description

Technical Field

[0001] This utility model relates to the field of bending machine technology, and in particular to a bending machine with positioning function. Background Technology

[0002] A bending machine is a machine that can bend thin plates. Its structure mainly includes a support, a worktable, and a hydraulically driven bending head. The bending head is driven by hydraulic pressure to move down and bend the workpiece on the worktable.

[0003] Since some parts to be bent need to be positioned and aligned so that the downward bending head is positioned in the middle of the part to be bent, the current method is mostly for workers to manually align them. This operation requires constant caution and poses certain safety hazards. In response, we have designed a bending machine with positioning function to solve the above-mentioned problem of needing to align the parts to be bent. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a bending machine with positioning function.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A bending machine with positioning function includes a table, a gantry frame fixed on the top of the table, a bending pressure plate driven by a hydraulic cylinder inside the gantry frame, a through hole on the top of the table, a bending plate fixed on the top of the through hole, and two symmetrical positioning members slidably arranged inside the through hole. A U-shaped pressure plate for pressing the positioning members to move is installed on the output shaft of the hydraulic cylinder.

[0007] The positioning component includes a movable block, with an inclined groove on the top of the two movable blocks facing away from each other, and a vertical groove continuous with the inclined groove on the outer wall of the movable block, and the bottom of the U-shaped pressure plate is adapted to the inclined groove and the vertical groove.

[0008] As a further embodiment of this utility model, an extrusion member is installed on the outer wall of the movable block. The extrusion member includes a sleeve rod, a pressure spring is fixed on the inner wall of the sleeve rod, and an insert rod fixed to the pressure spring is inserted into the sleeve rod. A positioning plate is fixed at the other end of the insert rod. A hole is opened on the movable block for the insert rod to pass through. The extrusion member includes a sleeve rod, an insert rod, a positioning plate, and a pressure spring. When the part to be bent is bent and deformed, if the positioning plate connected to the pressure spring is subjected to pressure, the pressure spring will contract and the positioning plate will move, which will not affect the deformation of the part to be bent.

[0009] As a further embodiment of this utility model, two positioning rods are fixed to the inner wall of the through hole, and a hole is provided on the movable block for the positioning rods to pass through. A sleeve block is fixedly fitted on the middle of the outer wall of the positioning rod, and springs are fixed at both ends of the sleeve block. The other end of the spring is fixed to the outer wall of the movable block.

[0010] In this design: the pressure spring has a certain strength to ensure that it will not deform when the positioning plate is pushed. It can only be compressed when subjected to strong pressure. In this design, when the bending process is subjected to a large deformation and pressure, the pressure spring will contract and the two positioning plates will move to ensure the deformation of the part to be bent.

[0011] As a further embodiment of this utility model, the U-shaped pressure plate is provided with a groove in the middle of the side plate used to squeeze the moving block, and the sleeve rod corresponds to the position of the groove.

[0012] As a further embodiment of this utility model, the hydraulic cylinder is fixed to the top of the gantry frame, the output shaft of the hydraulic cylinder is fixed with a mounting plate, the U-shaped pressure plate is fixed to the bottom of the mounting plate, the bottom of the U-shaped pressure plate is fixed with a mounting bracket, and the mounting bracket is fixed with a bent pressure plate.

[0013] As a further embodiment of this utility model, a notch is provided on the movable block at the position of the inclined groove, and the sleeve rod is fixed at the notch position.

[0014] The beneficial effects of this utility model are as follows:

[0015] This utility model employs a platform, gantry frame, hydraulic cylinder, mounting plate, bending pressure plate, bending table, positioning components, and U-shaped pressure plate. An extrusion component is installed on the positioning component, causing it to press the workpiece to be bent for alignment. When the extrusion component contacts the workpiece, the bottom of the U-shaped pressure plate slides within the vertical groove, preventing the two positioning components from approaching each other during bending. This effectively solves the problems raised in the background technology, achieving alignment and positioning without affecting the bending function.

[0016] This utility model: The extrusion component includes a sleeve rod, an insert rod, a positioning plate, and a pressure spring. When the part to be bent is bent and deformed, if the positioning plate connected to the pressure spring is subjected to pressure, the pressure spring will contract and the positioning plate will move, without affecting the deformation of the part to be bent.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0024] Reference Figure 1-4 A bending machine with positioning function includes a table 1, a gantry frame 2 fixed on the top of the table 1, a bending pressure plate 5 driven by a hydraulic cylinder 3 inside the gantry frame 2, a through hole 101 opened on the top of the table 1, a bending table plate 13 fixed on the top of the through hole 101, and two symmetrical positioning parts 6 slidably arranged inside the through hole 101. A U-shaped pressure plate 7 for pressing the positioning parts 6 to move is installed on the output shaft of the hydraulic cylinder 3.

[0025] The positioning component 6 includes a movable block 601. The top of the side of the two movable blocks 601 that is far apart from each other is provided with an inclined groove 602. The outer wall of the movable block 601 is provided with a vertical groove 603 that is continuous with the inclined groove 602. The bottom of the U-shaped pressure plate 7 is adapted to the inclined groove 602 and the vertical groove 603.

[0026] In this embodiment, an extrusion member 8 is installed on the outer wall of the movable block 601. The extrusion member 8 includes a sleeve rod 801, a pressure spring is fixed on the inner wall of the sleeve rod 801, and an insert rod 802 fixed to the pressure spring is inserted into the sleeve rod 801. A positioning plate 803 is fixed to the other end of the insert rod 802. A hole is opened on the movable block 601 for the insert rod 802 to pass through. The extrusion member 8 includes a sleeve rod 801, an insert rod 802, a positioning plate 803 and a pressure spring. When the part to be bent is bent and deformed, if the positioning plate 803 connected to the pressure spring is subjected to pressure, the pressure spring will contract and the positioning plate 803 will move, which will not affect the deformation of the part to be bent.

[0027] In this embodiment, two positioning rods 10 are fixed on the inner wall of the through hole 101. The moving block 601 has a hole for the positioning rods 10 to pass through. A sleeve block 11 is fixedly sleeved on the middle of the outer wall of the positioning rod 10. Springs 12 are fixed at both ends of the sleeve block 11. The other end of the spring 12 is fixed to the outer wall of the moving block 601.

[0028] In this design: the pressure spring has a certain strength to ensure that it will not deform when the positioning plate 803 is pushed. It can only be compressed when subjected to strong pressure. In this design, when the bending is subjected to a large deformation pressure, the pressure spring will contract and the two positioning plates 803 will move to ensure the deformation of the part to be bent.

[0029] In this embodiment, the U-shaped pressure plate 7 is used to squeeze the middle of the side plate of the moving block 601, which is provided with a groove, and the sleeve rod 801 corresponds to the groove position.

[0030] In this embodiment, the hydraulic cylinder 3 is fixed to the top of the gantry frame 2, the output shaft of the hydraulic cylinder 3 is fixed with a mounting plate 4, the U-shaped pressure plate 7 is fixed to the bottom of the mounting plate 4, the bottom of the U-shaped pressure plate 7 is fixed with a mounting bracket, and the mounting bracket is fixed with a bending pressure plate 5.

[0031] In this embodiment, a notch 604 is provided on the moving block 601 at the position of the inclined groove 602, and the sleeve rod 801 is fixed at the position of the notch 604.

[0032] Working principle: The system comprises a platform 1, gantry frame 2, hydraulic cylinder 3, mounting plate 4, bending pressure plate 5, bending table 13, positioning element 6, and U-shaped pressure plate 7. The positioning element 6 includes a moving block 601, an inclined groove 602, and a vertical groove 603. The workpiece to be bent is placed on top of the bending table 13. Through the operation of the hydraulic cylinder 3, the U-shaped pressure plate 7 and the bending pressure plate 5 move downwards. First, the U-shaped pressure plate 7 moves within the inclined groove 602, forcing the two moving blocks 601 closer together. An extrusion element 8 is installed on the positioning element 6, causing the extrusion element 8 to... The part to be bent is straightened by pressing. When the pressing part 8 is in contact with the part to be bent, the bottom of the U-shaped pressure plate 7 slides within the vertical groove 603. This prevents the two positioning parts 6 from getting closer to each other during bending, thus achieving straightening and positioning without affecting the bending effect. The pressing part 8 includes a sleeve rod 801, an insert rod 802, a positioning plate 803, and a pressure spring. When the part to be bent is deformed, if the positioning plate 803 connected to the pressure spring is subjected to pressure, the pressure spring will contract, and the positioning plate 803 will move, without affecting the deformation of the part to be bent.
