Description

Technical Field

[0001] This utility model relates to the technical field of bending machines, specifically a high-torque intelligent control bending machine with shock absorption function. Background Technology

[0002] The hydraulic system of an intelligent CNC bending machine is the core component that provides pressure and power. The hydraulic oil pump generates high-pressure oil through the drive of an electric motor. This oil drives the upper and lower dies through hydraulic cylinders. The piston of the hydraulic cylinder driven by a high-torque motor has higher bending force and stability, making it suitable for processing thick metal sheets.

[0003] When a bending machine is working, the drive components, especially the hydraulic equipment, will generate a certain amount of vibration, which can cause the equipment parts to loosen, affect the service life of the equipment, and generate a lot of noise. Existing vibration damping devices are generally installed on the base of the bending machine for overall vibration damping. Since all the components of the bending machine are fixed on the frame, the vibration generated by the drive components on the bending machine will still affect other components through the frame.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example 1

[0027] Please refer to the appendix. Figure 1-8 A high-torque intelligent control bending machine with shock absorption function includes a machine body 1, an upper mold mechanism 3, a bottom mold mechanism 2, and an isolation and shock absorption mechanism 4, wherein:

[0028] The upper mold mechanism 3 includes a mounting platform 31 movably connected to the machine body 1 and equipped with multiple hydraulic cylinders. The bottom of the mounting platform 31 is equipped with a pressure plate 32 driven by hydraulic pressure and a bending upper mold 33.

[0029] The isolation and shock absorption mechanism 4 includes a fixed platform 42 installed on the body 1. Multiple buffer platforms 421 are installed on the upper end of the fixed platform 42. A mounting frame 311 is installed at the rear end of the mounting platform 31. Multiple shock absorption springs 423 are installed between the mounting frame 311 and the connecting platform 312.

[0030] The bottom mold mechanism 2 includes a bottom mold platform 21 disposed at the front end of the machine body 1, and a bending bottom mold 22 corresponding to and cooperating with the bending upper mold 33 is installed on the upper end of the bottom mold platform 21.

[0031] Please refer to the appendix. Figure 5 , Figure 6 , Figure 8The isolation and shock absorption mechanism 4 also includes a support platform 41. A connecting platform 312 is symmetrically installed on the back of the mounting platform 31. Multiple roller groups 314 are installed at the bottom of the connecting platform 312. The connecting platform 312 is movably connected to the support platform 41.

[0032] Furthermore, the roller assembly 314 is composed of multiple rollers connected in series in the same roller seat, and the upper end of the support platform 41 is provided with a roller groove 411, and the roller assembly 314 is movably connected to the roller groove 411.

[0033] In this embodiment, the vibration generated during the cylinder driving process is transmitted to the mounting frame 311 through the mounting platform 31. At the same time, the mounting platform 31 and the mounting frame 311 move slightly under the influence of vibration. The roller group 314 can make the small movement of the mounting frame 311 and the mounting platform 31 smoother, and at the same time support the mounting platform 31 to avoid friction between the mounting platform 31 and the supporting components, which would generate additional vibration and noise.

[0034] Please refer to the appendix. Figure 7 The mounting bracket 311 is equipped with a plurality of positioning cylinders 313, the buffer platform 421 is equipped with a plurality of positioning posts 422 that are movably connected to and fit with the positioning cylinders 313, and the shock-absorbing spring 423 is wrapped around the outside of the positioning posts 422 and located between the positioning posts 422 and the positioning cylinders 313.

[0035] Furthermore, the buffer platforms 421 are arranged in pairs to clamp the mounting frame 311 between the two buffer platforms 421, and the positioning cylinders 313 are symmetrically installed on both sides of the mounting frame 311.

[0036] In this embodiment, the two-by-two buffer platforms 421 can provide shock absorption and buffering for the mounting frame 311 from two directions. This not only provides better shock absorption and buffering, but also prevents the positional misalignment between the mounting frame 311 and the mounting platform 31 from affecting the bending accuracy. Example 2

[0037] Based on the above embodiment one, please refer to the appendix. Figure 3 , Figure 4 The bottom mold platform 21 is independently set at the front end of the machine body 1, and a fixing seat 24 for fixing is installed at the bottom of the bottom mold platform 21.

[0038] Furthermore, a plurality of calibration columns 23 are symmetrically installed at the rear end of the bottom mold platform 21, and a calibration platform 11 is symmetrically installed at the front end of the body 1. The front end of the calibration platform 11 is provided with a plurality of calibration holes 12 that are movably connected to the calibration columns 23.

[0039] In this embodiment, the bottom mold and the body 1 are designed independently. The vibration generated by the hydraulic equipment or other equipment of the body 1 during operation cannot be transmitted to the bottom mold, so that the bottom mold is not affected. At the same time, the positioning and installation by inserting the calibration column 23 into the calibration hole 12 will not affect the alignment of the bottom mold and the upper mold.

[0040] The working principle and usage process of this utility model are as follows: During the operation of the equipment, after the workpiece to be bent is placed on the upper end of the bending bottom die 22 and fixed stably, the hydraulic system drives the hydraulic cylinder on the mounting platform 31 to start and drive the pressure plate 32 to move downward. The pressure plate 32 drives the bending upper die 33 to move downward. During this process, the vibration generated during the hydraulic cylinder drive is transmitted to the mounting frame 311 through the mounting platform 31. At the same time, the mounting platform 31 and the mounting frame 311 move slightly under the influence of vibration. At this time, the mounting frame 311 vibrates slightly and moves to resist the shock-absorbing spring 423. The shock-absorbing spring 423 is squeezed and generates a counterforce to keep the mounting frame 311 stable, buffering the vibration and weakening it. The weakened and buffered vibration transmitted to the frame can no longer affect the equipment.
