Description

Technical Field

[0001] The utility model relates to the technical field of bending machines, in particular to a bending machine working platform with a buffer structure. Background Art

[0002] A bending machine is a machine that can bend thin plates. Its structure mainly includes a bracket, a workbench and a clamping plate. The workbench is placed on the bracket. The workbench is composed of a base and a pressure plate. The base is connected to the clamping plate by a hinge. The base is composed of a base shell, a coil and a cover plate. The coil is placed in the recess of the base shell, and the top of the recess is covered with a cover plate. When in use, the coil is energized by a wire, and after power is turned on, an attractive force is generated on the pressure plate, thereby clamping the thin plate between the pressure plate and the base.

[0003] The existing bending machine working platform with a buffer structure is generally improved to address the problem that when a device fails, the workpiece is easily subjected to excessive force during bending, the workpiece is easily broken and fragments are splashed, and nearby workers are easily injured, and the protection is very poor. For example, a bending machine protection device disclosed in the authorized Chinese patent CN219188436U can be used in conjunction with structures such as a workbench, support legs, bending box, lower mold, protective door, slider, screw, fixed plate, first gear, first sleeve, screw rod, first bevel gear, servo motor, second sleeve, connecting plate, upper mold, second bevel gear, rotating shaft, support plate, second gear, explosion-proof glass window and anti-slip pad. When a failure occurs during the bending of the workpiece, the protective door is in a closed state, and the splashing workpiece fragments will be blocked by the protective door to avoid injuring the workers, thereby improving the safety of the device.

[0004] However, the above-mentioned cited documents are prone to some safety problems when in use. For example, the device will generate vibrations during operation, and long-term vibrations will affect the service life of the device. When encountering some sudden collisions, there are no good buffering measures to protect the device, which leads to the need to improve the use effect of the existing bending machine working platform.

DETAILED DESCRIPTION

[0026] The technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0027] See also Figure 1-3 The utility model provides a technical solution: a bending machine working platform with a buffer structure, comprising a buffer box 1, a bending machine workbench 2 and a protective cover 3, one side of the protective cover 3 is fixedly installed on one side of the bending machine workbench 2, and the bending machine workbench 2 is slidably connected to the outer side of the buffer box 1; a shock absorbing mechanism 400 for buffering and shock absorption is installed in the buffer box 1;

[0028] Through the mutual cooperation between the bending machine worktable 2, the protective cover 3 and the shock absorbing mechanism 400 on the buffer box 1, it is possible to buffer and absorb vibrations when the bending machine worktable 2 generates vibrations during operation to prevent the occurrence of malfunctions and protect the device. At the same time, it can also provide buffering protection when encountering sudden collisions, thereby effectively improving the use effect of the existing bending machine work platform.

[0029] In this embodiment, the shock absorbing mechanism 400 is a structure for buffering and shock absorption.

[0030] like Figure 1 , Figure 2 and Figure 3 As shown, the shock absorbing mechanism 400 includes sliding blocks 401 respectively fixedly mounted on both sides of the buffer box 1 and a movable plate 403 slidably connected to the inner side of the buffer box 1, a damper 404 fixedly connected to the inner side of the bending machine workbench 2 is fixedly connected on the side of the movable plate 403 close to the protective cover 3, a preliminary buffer assembly is installed on the side of the movable plate 403 close to the protective cover 3, and a fixed block 406 is fixedly installed on the other side, at least two groups of hinge assemblies are installed on both sides of the fixed block 406, and a secondary buffer assembly is connected to the side of the hinge assembly away from the fixed block 406, and the secondary buffer assembly is installed in the buffer box 1.

[0031] It should be noted that a slide groove 402 for the sliding block 401 to slide against is provided on the inner wall of the bending machine worktable 2 in order to improve the sliding stability between the bending machine worktable 2 and the buffer box 1 while limiting the moving distance of the bending machine worktable 2 .

[0032] It is understandable that there are multiple dampers 404 and the multiple dampers 404 are evenly distributed in order to consume the energy in the mechanical system to reduce vibration and impact and absorb the inherent vibration energy generated during the bending operation.

[0033] In addition, the preliminary buffer assembly includes a support rod 4051, a No. 1 return spring 4052, a movable slider 4053 and a U-shaped connecting frame 4054; one side of the U-shaped connecting frame 4054 is fixedly installed on the inner wall of the bending machine workbench 2, one end of the support rod 4051 is fixedly connected to one side of the movable plate 403, and the other end passes through the U-shaped connecting frame 4054 and extends to one side of the movable slider 4053 and is fixedly connected to the movable slider 4053. The inner side of the No. 1 return spring 4052 is sleeved on the outer side of the support rod 4051 and is located below the U-shaped connecting frame 4054, so as to cooperate with the damper 404 to perform preliminary shock absorption when the buffer box 1 is working.

[0034] In this embodiment, the projection of the movable plate 403 in the first direction is a rectangle with a length of L and a width of W. The first direction is perpendicular to the axial direction of the support rod 4051. The length of the inner side of the buffer box 1 is L1 and the width of the inner side is W1. L=L1, W=W1, so that the movable plate 403 can slide closely on the inner side of the buffer box 1.

[0035] It should also be noted that the projection of the movable slider 4053 in the second direction is a rectangle with a length of D and a width of G. The second direction is perpendicular to the axial direction of the support rod 4051. The length of the inner side of the U-shaped connecting frame 4054 is D1 and the width of the inner side is G1. D=D1, G=G1, so that the movable slider 4053 can slide closely on the inner side of the U-shaped connecting frame 4054.

[0036] It needs to be further explained that the articulated assembly includes an articulated seat No. 1 4071, an articulated rod 4072 and an articulated seat No. 2 4073; one side of the articulated seat No. 1 4071 is fixedly mounted on one side of the fixed block 406, one end of the articulated rod 4072 is hinged to the inner side of the No. 1 articulated seat 4071 through a pin, and the other end is hinged to the inner side of the No. 2 articulated seat 4073 through a pin, and the No. 2 articulated seat 4073 is connected to the secondary buffer assembly so that the secondary buffer assembly can be pushed to move under the thrust generated by the fixed block 406 through the mutual articulation of the No. 1 articulated seat 4071, the articulated rod 4072 and the No. 2 articulated seat 4073, so as to perform further buffering and shock absorption.

[0037] It should also be noted that the secondary buffer assembly includes a sliding rod 4081, an adjusting block 4082 and a No. 2 return spring 4083; both ends of the sliding rod 4081 are respectively fixedly connected to the inner wall of the buffer box 1, the inner side of the adjusting block 4082 is slidably connected to the outer side of the sliding rod 4081, the inner side of the No. 2 return spring 4083 is sleeved on the outer side of the sliding rod 4081, and the No. 2 return spring 4083 is located on the side of the adjusting block 4082 away from the No. 2 hinge seat 4073, in order to further improve the shock absorbing and buffering effect of the device.

[0038] It should also be noted that there are two sliding rods 4081, and the two sliding rods 4081 are distributed in a mirror-symmetrical manner in order to make the movement of the adjustment block 4082 more stable.

[0039] It should also be further explained that the natural length of the No. 2 return spring 4083 is Q, and the distance from the side of the adjustment block 4082 close to the fixed block 406 to the inner wall of the buffer box 1 is E, and Q=E. This is so that when the adjustment block 4082 moves, the No. 2 return spring 4083 can push the adjustment block 4082 back to its original position under the thrust generated during resetting.

[0040] The working principle of the above embodiment is:

[0041] When the bending machine workbench 2 is performing bending work, the bending machine workbench 2 is vibrated by external force, thereby driving the sliding block 401 to move along the sliding groove 402, ensuring the directional movement of the bending machine workbench 2 and preventing it from shaking left and right. At this time, the damper 404 and the U-shaped connecting frame 4054 are subjected to force at the same time, and the support rod 4051, the No. 1 return spring 4052 and the moving slider 4053 cooperate with each other to form a certain buffering force under the extrusion force, which partially consumes the force exerted on the bending machine workbench 2 and plays a certain buffering role, thereby reducing the amplitude of the bending machine workbench 2. At the same time, the U-shaped connecting frame 4054 moves The movement drives the movable plate 403 to move in the direction away from the protective cover 3 and generates a thrust. At this time, the movement of the No. 1 hinged seat 4071 drives the hinged hinge rod 4072 to move, and drives the No. 2 hinged seat 4073 hinged thereon to move in the horizontal direction. At this time, the No. 2 hinged seat 4073 drives the adjustment block 4082 to move along the outer side of the sliding rod 4081 under the thrust generated by the horizontal movement of the No. 2 hinged seat 4073, and makes the No. 2 return spring 4083 generate an elastic force corresponding to its power when elastically compressed and push the adjustment block 4082 back, which can further partially offset the vibration and can offset the amplitude generated when the device is working to the maximum extent.

[0042] Compared with the prior art: the bending machine working platform with a buffer structure, through the mutual cooperation between the bending machine working table 2, the protective cover 3, and the shock absorbing mechanism 400 on the buffer box 1, can buffer and absorb vibrations when the bending machine working table 2 generates vibrations during operation, prevent the occurrence of faults, and protect the device. At the same time, it can also provide buffer protection when encountering sudden collisions, thereby effectively improving the use effect of the existing bending machine working platform and solving the problem of poor use effect of the existing bending machine working platform.

[0043] It should be noted that the terms "include", "comprises" or any other variations thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, an element defined by the sentence "comprises a ..." does not exclude the existence of other identical elements in the process, method, article or device including the element.

[0044] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that many changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention.
