Description

Technical Field

[0001] This invention relates to the field of bending machine technology, specifically to an auxiliary material support device for bending machines. Background Technology

[0002] The material support device is a key component of a bending machine, integrating material blocking and support functions. It achieves precise control through a servo motor and CNC system, significantly improving the accuracy and efficiency of sheet metal processing. It mainly includes the main frame, brush table, and finger blocking assembly.

[0003] However, existing material support devices still have some problems in practical use: existing material support devices can only support and block the rear end of the material that needs to be bent, but when the material is bent, the rear end of the material will flip. If the rear end of the material is long, it will tilt upwards when bending and flipping, and due to its own weight, it is easy to cause vibration, resulting in poor stability of the sheet metal and making the process more troublesome. This will affect the overall bending quality and efficiency of the material. To address these issues, we propose an auxiliary material support device for bending machines. Summary of the Invention

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0035] Example: Figure 1-12 As shown, the present invention provides an auxiliary material support device for a bending machine, including a device base 1, an auxiliary turning mechanism 2 fixedly installed on one side of the top of the device base 1, a material support mechanism 3 provided on the other side of the top of the device base 1, and an adjustment mechanism 4 provided between the auxiliary turning mechanism 2 and the material support mechanism 3.

[0036] The material support mechanism 3 includes two first connecting crossbeams 31. Multiple sets of material support components 5 are evenly distributed on the two first connecting crossbeams 31.

Multiple sets of support seats 33 are fixedly installed on the second connecting crossbeams 32. The bottom end of the support seat 33 is in contact with the upper surface of the device base 1. By setting multiple sets of support seats 33, the bottom end of the support seat 33 is in contact with the upper surface of the device base 1, thus supporting one end of the material support mechanism 3.

[0037] The support component 5 includes a support crossbar 51. One end of the support crossbar 51 is integrally formed with a first fixing frame 511, which is fixedly installed on a first connecting crossbar 31. The other end of the support crossbar 51 away from the first fixing frame 511 is integrally formed with a second fixing frame 513, which is fixedly installed on a second connecting crossbar 32. A first ball bearing 512 is rolled on the side of the support crossbar 51 closest to the first fixing frame 511. By setting the first ball bearing 512, the sheet metal is placed on the first ball bearing 512 and rolls during folding. The support and support crossbar 51 is vertically fitted with multiple sets of evenly distributed longitudinal sliding cylinders 52. The side ends of the longitudinal sliding cylinders 52 are fixedly installed with racks 53. The top of the longitudinal sliding cylinders 52 is provided with ball grooves 521. The ball grooves 521 are movably fitted with second balls 55. By setting the second balls 55, the plate is placed on the second balls 55 for rolling support when folding. The outer side of the longitudinal sliding cylinders 52 is slidably fitted with sliding sleeve frames 58. The side ends of the sliding sleeve frames 58 are fixedly installed with positioning top rods 59. The sliding sleeve frames 58 facilitate vertical sliding on the outer side of the longitudinal sliding cylinders 52.

[0038] The longitudinal sliding cylinder 52 has an oil inlet groove 522 in the middle, the top of the oil inlet groove 522 and the bottom of the ball groove 521 are connected to each other. The top of the longitudinal sliding cylinder 52 has an annular groove 523, and multiple oil discharge grooves 524 are evenly distributed on the annular groove 523.

A first oil guide branch pipe 572 is fixedly installed between two adjacent first tee pipes 57. Multiple first oil guide branch pipes 572 are used to connect multiple sets of first tee pipes 57. A second oil guide branch pipe 573 is fixedly installed between two adjacent second tee pipes 571. Multiple second oil guide branch pipes 573 are used to connect multiple sets of second tee pipes 571. An oil inlet pipe 574 is fixedly installed at one end of the first tee pipe 57, and an oil return pipe 575 is fixedly installed at one end of the second tee pipe 571. An oil return pipe 575 is fixedly installed at the other end of the first tee pipe 57. Both ends of pipe 7 and the second tee pipe 571 are fixedly fitted with caps to seal the ends of the first tee pipe 57 and the second tee pipe 571 at the other end. In use, the ends of the oil inlet pipe 574 and the oil return pipe 575 are connected to the output port and input port of the lubricating oil circulation system, respectively, to control the start of the lubricating oil circulation system. The lubricating oil is introduced into the ball groove 521 through the oil inlet pipe 574, the first tee pipe 57, the first oil guide branch pipe 572, the first connector 56, and the oil inlet groove 522 to continuously lubricate the second balls 55 in multiple sets of ball grooves 521, preventing the blockage of multiple sets of second balls 55 from affecting the rolling support of the plate. The lubricating oil also flows into the lubricating oil circulation system through multiple oil drain grooves 524 and ring grooves 523, oil return grooves 525, the second connector 561, the second tee pipe 571, the second oil guide branch pipe 573, and the oil return pipe 575.

[0040] A first gear 54 is movably mounted on one side of the support crossbar 51 near the longitudinal sliding cylinder 52. The first gear 54 meshes with a rack 53. A first shaft 541 is fixedly mounted in the middle of the first gear 54. The first shaft 541 is rotatably mounted in the support crossbar 51. A second motor 542 is fixedly mounted on one side of the support crossbar 51 near the first shaft 541. The drive end of the second motor 542 is fixedly mounted to the end of the first shaft 541. By controlling the second motor 542 to turn, the first shaft 541 and the first gear 54 are driven to rotate. Since the first gear 54 and the rack 53 mesh, the longitudinal sliding cylinder 52 is driven to slide up and down in the support crossbar 51, flexibly adjusting the height position of the second ball bearing 55.

[0041] A second gear 581 is movably mounted on one side of the sliding sleeve frame 58. The second gear 581 is meshed with a rack 53. A second shaft 582 is fixedly mounted in the middle of the second gear 581. The second shaft 582 is rotatably mounted on one side of the sliding sleeve frame 58. A third motor 583 is fixedly mounted on the side of the sliding sleeve frame 58 near the second shaft 582. The drive end of the third motor 583 and the end of the second shaft 582 are fixedly mounted. By controlling the third motor 583 to turn on, the second shaft 582 and the second gear 581 are driven to rotate. Since the second gear 581 and the rack 53 are meshed, the sliding sleeve frame 58 is driven to slide up and down on the outside of the longitudinal sliding cylinder 52, flexibly adjusting the height position of the positioning top rod 59.

[0042] The auxiliary flipping mechanism 2 includes two symmetrically distributed flipping brackets 21. The flipping brackets 21 are fixedly installed on one side of the top of the device base 1. A flipping horizontal shaft 22 is rotatably installed on the top of each flipping bracket 21. During installation, the position of the flipping horizontal shaft 22 is vertically aligned with the position of the folding pressure knife, which facilitates the auxiliary support for flipping the plate during subsequent bending and prevents vibration when the rear end of the plate is long. An L-shaped bracket 23 is fixedly installed on the inner end of each flipping horizontal shaft 22. An auxiliary support frame 24 is vertically installed on the inner end of each L-shaped bracket 23. A third connecting horizontal frame 26 is vertically installed on the end of each auxiliary support frame 24 away from the L-shaped bracket 23. Multiple third ball bearings 241 are rolled and clamped on the top of each auxiliary support frame 24. By setting multiple third ball bearings 241, the plate is placed on multiple third ball bearings 241 for rolling support during folding. By controlling the flipping horizontal shaft 22, L-shaped brackets 23 and third connecting horizontal frame 26 to rotate around the flipping horizontal shaft 22, the plate can be assisted in flipping and prevent vibration when the rear end of the plate is long.

[0043] The outer ends of the flipping horizontal shaft 22 are all fixedly installed with transmission worm gears 25. The bottom of each transmission worm gear 25 is meshed with a transmission worm 251. Both ends of the transmission worm 251 are rotatably mounted with rotating brackets 252. The top of the flipping bracket 21 is fixedly installed with an auxiliary seat 211. The rotating bracket 252 is fixedly mounted on the auxiliary seat 211. The side of the auxiliary seat 211 near the transmission worm 251 is fixedly installed with a first motor 253. The drive end of the first motor 253 is fixedly installed with one end of the transmission worm 251. By controlling the first motor 253 to drive the transmission worm 251 to rotate, the transmission worm gears 25 will rotate. This controls the flipping horizontal shaft 22, the L-shaped bracket 23 and the third connecting horizontal frame 26 to rotate around the flipping horizontal shaft 22 as the axis. This helps to support the plate to flip, preventing vibration when bending when the rear end of the plate is long, thereby improving the bending effect and quality of the plate.

[0044] The adjustment mechanism 4 includes a first fixed seat 41 and a second fixed seat 42. The first fixed seat 41 is provided in multiple sets and is fixedly installed on the first connecting crossbeam 31. The second fixed seat 42 is provided in multiple sets and is fixedly installed on the third connecting crossbeam 26. A guide sliding cross shaft 43 is fixedly installed at the bottom of each of the first fixed seats 41. The end of the guide sliding cross shaft 43 away from the first fixed seat 41 is slidably engaged with the bottom of the corresponding second fixed seat 42. By setting the first fixed seat 41, the second fixed seat 42, and the guide sliding cross shaft 43, the auxiliary turning mechanism 2 and the material supporting mechanism 3 are connected and installed. The guide sliding cross shaft 43 can slide at the bottom of the second fixed seat 42.

[0045] The adjustment mechanism 4 also includes a third fixed seat 44 and a fourth fixed seat 45. The third fixed seat 44 is fixedly installed in the middle of the first connecting crossbeam 31, and the fourth fixed seat 45 is fixedly installed in the middle of the third connecting crossbeam 26. A telescopic cylinder 46 is fixedly installed at the bottom of the third fixed seat 44, and the drive end of the telescopic cylinder 46 is fixedly installed at the bottom of the fourth fixed seat 45. By controlling the opening of the telescopic cylinder 46, the third fixed seat 44 is driven to control the material support mechanism 3 to move horizontally in a stable manner, and the horizontal position of the multiple sets of longitudinal sliding cylinders 52 on the material support mechanism 3 is adjusted. The guide horizontal shaft 43 slides at the bottom of the corresponding second fixed seat 42, thereby improving the stability of the horizontal movement of the material support mechanism 3.

[0046] Working principle: When in use, install the auxiliary material support device and the bending machine. Install the auxiliary material support device at the rear end of the bending machine so that the position of the folding pressure knife of the bending machine and the position of the flipping horizontal axis 22 are vertically aligned, and the flipping horizontal axis 22 is located directly below the position of the folding pressure knife.

[0047] The rear end of the sheet metal is passed through the folding pressure knife of the folding machine. At this time, the sheet metal is supported by rolling on multiple third ball bearings 241 and first ball bearings 512. According to the end of the sheet metal, the telescopic cylinder 46 is opened to drive the third fixed seat 44 to control the material support mechanism 3 to move horizontally. The horizontal position of multiple sets of longitudinal sliding cylinders 52 on the material support mechanism 3 is adjusted so that the side end of the longitudinal sliding cylinder 52 at the initial position contacts the end of the sheet metal to limit and stop the material. Then, the folding pressure knife is pressed down to bend the rear end of the sheet metal.

[0048] After the board is bent a certain distance, many bending parts appear at the rear end of the board, and the length of the rear end of the board increases. When the board is bent again, the horizontal movement of the support mechanism 3 is controlled, and the horizontal position of multiple sets of longitudinal sliding cylinders 52 on the support mechanism 3 is adjusted so that the side end of the longitudinal sliding cylinder 52 at the end position contacts the end of the board to limit and stop the board.

[0049] Subsequently, the second motor 542 at the position of the multiple sets of longitudinal sliding cylinders 52 is activated to drive the first shaft 541 and the first gear 54 to rotate. Since the first gear 54 and the rack 53 are meshed, the longitudinal sliding cylinder 52 is driven to slide up and down in the support crossbar 51, flexibly adjusting the height position of the second ball 55 until the second ball 55 contacts the lower surface of each part of the plate to provide effective and comprehensive support.

[0050] Subsequently, the third motor 583 on the longitudinal slide cylinder 52 at the control end position drives the second shaft 582 and the second gear 581 to rotate. Since the second gear 581 and the rack 53 are meshed, the sliding sleeve frame 58 is driven to slide up and down on the outside of the longitudinal slide cylinder 52, flexibly adjusting the height of the positioning rod 59 so that the bottom end of the positioning rod 59 contacts the upper surface of the end of the plate, positioning the end of the plate and improving the stability of the subsequent plate bending.

[0051] Subsequently, the folding pressure knife is pressed down again to bend the rear end of the board. At the same time, the first motor 253 is turned on to drive the transmission worm gear 251 to rotate the transmission worm wheel 25. This controls the flipping horizontal axis 22, the L-shaped bracket 23 and the third connecting horizontal frame 26 to rotate around the flipping horizontal axis 22. This controls the material support mechanism 3 to rotate around the flipping horizontal axis 22, assisting in the flipping of the board and preventing vibration when the rear end of the board is long during bending.

[0052] Because multiple sets of longitudinal sliding cylinders 52 are set up, they can be adapted to the auxiliary material blocking and auxiliary material support flipping of end plates of different lengths, as well as the comprehensive auxiliary support material blocking and material support flipping of end plates with different bending shapes, which improves the flexibility and effectiveness of the whole device.
