Technical Field

[0001] The utility model relates to the technical field of vibration reduction mechanisms, in particular to a vibration reduction mechanism for a material pressing plate of a milling machine. Background Art

[0002] In the processing of copper plates and strips, milling cutters are used to remove defects such as oxidation, indentations, cracks, and segregation on the surface of hot-rolled or continuously cast strips. This is the milling machine equipment. When the copper plates and strips are milled through the milling machine, the two groups of feeders in front and behind the milling machine are pressed down hydraulically to press the plate, and the material is conveyed by the motor to achieve the effect of smoother material milling and better strip surface quality.

[0003] However, this type of milling has some problems. Because the production line is controlled by speed control, the strip has no tension, and the distance between the milling machine and the feeders on both sides is far. When the thickness of the milling material is thin or the production line speed is fast, the amplitude generated by the equipment and the strip is large, and the noise generated increases, affecting the service life of the milling cutter and the equipment itself, bringing inconvenience and safety hazards to the production and observation of the copper strip, and also causing the surface of the copper strip to often have defects due to vibration after milling, and not be smooth enough. Utility Model Content

[0004] In response to the deficiencies in the prior art, the utility model provides a vibration damping mechanism for a material pressure plate of a milling machine, which solves the problem that due to the speed control mode of the production line, the strip has no tension, and the distance between the milling machine and the feeders on both sides is relatively far. When the thickness of the milled material is thin or the speed of the production line is fast, the amplitude generated by the equipment and the strip is large, and the noise generated increases, affecting the service life of the milling cutter and the equipment body, bringing inconvenience and safety hazards to the production and observation of the copper strip, and also causing the surface of the copper strip to often have defects and be not smooth due to vibration after milling.

[0005] The utility model provides the following technical solution: a milling machine material pressing plate vibration reduction mechanism, comprising a feeder, a side of the feeder is provided with a discharge port, a copper plate strip body is provided in the discharge port, and two sets of material pressing plate vibration reduction components are symmetrically provided on both sides of the discharge port;

[0006] The material pressure plate vibration damping assembly includes a fixed connecting plate arranged on the side of the feeder end portion, a cylinder mounting bracket is arranged in the middle of the side of the fixed connecting plate, two driving cylinders are symmetrically installed on the cylinder mounting bracket, and an electromagnetic valve is installed on the top of the driving cylinder, the output end of the bottom of the driving cylinder is connected to the resistance connecting plate, the side of the resistance connecting plate is connected to the installation connecting plate, a rubber pressure plate is arranged on the side of the installation connecting plate, two fixing screws are symmetrically arranged on the rubber pressure plate, and two connecting sockets are symmetrically opened at both ends of the installation connecting plate, the end of the fixing screw passes through the connecting socket and is sleeved with a fixing nut, and felt is arranged on the side of the rubber pressure plate, and a pressure plate limit frame is arranged on the side of the feeder, and the two sides of the pressure plate limit frame are fixedly connected to the feeder through fixed connecting blocks.

[0007] Preferred technical solution 1: the rubber pressure plate and the felt both extend into the pressure plate limiting frame, and two stable connecting plates are symmetrically provided on the sides of the cylinder mounting frame.

[0008] Preferred technical solution 2: A fixing screw is inserted into the stable connecting plate, and the bottom end of the fixing screw is threadedly inserted into the fixed connecting plate.

[0009] Preferred technical solution three: two limiting slots are symmetrically provided at the end of the pressure plate limiting frame, and two limiting plugs are symmetrically provided at the end of the rubber pressure plate, and the limiting plugs are slidably inserted in the limiting slots.

[0010] This solution can make the rubber pressure plate slide up and down more smoothly in the pressure plate limiting frame.

[0011] Preferred technical solution 4: Both ends of the felt are curved.

[0012] This solution enables the felt to better resist and limit the side of the copper strip body when it is pushed by the driving cylinder.

[0013] Preferred technical solution five: the stable connecting plate is bent in an L-shape, and the stable connecting plate is inserted into the side of the fixed connecting plate.

[0014] This solution can make the stable connecting plate more firmly connected to the fixed connecting plate.

[0015] Compared with the prior art, the present invention provides a vibration reduction mechanism for a material pressing plate of a milling machine, which has the following beneficial effects:

[0016] (1) The utility model symmetrically arranges two material pressure plate vibration damping assemblies on both sides of the discharge port, wherein the driving cylinder in the material pressure plate vibration damping assembly can push the resistance connecting plate, so that the resistance connecting plate drives the rubber pressure plate and the felt arranged on its side to move toward the upper and lower sides of the copper plate strip body, thereby limiting the vibration amplitude of the copper plate strip body when it is discharged from the discharge port at high speed, ensuring that the copper plate strip body is not restricted by the strip thickness and production line speed when entering the milling machine, better improving the equipment stability and production efficiency, and making the material more stable in operation during milling than when the mechanism is not included, thereby achieving high-quality milling effect. At the same time, by adding the material pressure plate vibration damping assembly, this milling method can effectively improve the equipment operation efficiency, reduce energy loss, and achieve high-speed and high-surface quality milling of high-precision copper plates.

DETAILED DESCRIPTION

[0022] See also Figure 1-4 ,

[0023] Embodiment 1: A material pressing plate vibration damping mechanism of a milling machine includes a feeder 1, a discharge port 2 is provided on the side of the feeder 1, a copper plate strip body 3 is provided in the discharge port 2, and two groups of material pressing plate vibration damping components 4 are symmetrically provided on both sides of the discharge port 2.

[0024] The material pressure plate vibration damping assembly 4 includes a fixed connecting plate 401 arranged on the side of the end of the feeder 1, and a cylinder mounting frame 402 is arranged in the middle of the side of the fixed connecting plate 401. Two driving cylinders 403 are symmetrically installed on the cylinder mounting frame 402, and solenoid valves 404 are installed on the top of the driving cylinders 403. The output end of the bottom of the driving cylinder 403 is connected to a resistance connecting plate 405, and the side of the resistance connecting plate 405 is connected to an installation connecting plate 406. A rubber pressure plate 407 is arranged on the side of the installation connecting plate 406, and two fixing screws 408 are symmetrically arranged on the rubber pressure plate 407. Two connecting sockets 409 are symmetrically opened at both ends of the installation connecting plate 406.

[0025] The end of the fixing screw 408 passes through the connecting socket 409 and is sleeved with a fixing nut 410. A felt 411 is provided on the side of the rubber pressure plate 407. A pressure plate limit frame 412 is provided on the side of the feeder 1. The two sides of the pressure plate limit frame 412 are fixedly connected to the feeder 1 through the fixed connecting blocks 413. The rubber pressure plate 407 and the felt 411 both extend into the pressure plate limit frame 412. Two stable connecting plates 416 are symmetrically provided on the side of the cylinder mounting frame 402. A fixing screw 417 is inserted into the stable connecting plate 416. The bottom end of the fixing screw 417 is threadedly inserted into the fixed connecting plate 401.

[0026] Example 2: The difference between this example and Example 1 is that two limit slots 414 are symmetrically provided at the end of the pressure plate limit frame 412, and two limit plugs 415 are symmetrically provided at the end of the rubber pressure plate 407, and the limit plugs 415 are slidably inserted in the limit slots 414.

[0027] This allows the rubber pressing plate 407 to slide up and down in the pressing plate limiting frame 412 more smoothly.

[0028] Embodiment 3: The difference between this embodiment and embodiment 1 is that both ends of the felt 411 are curved.

[0029] This allows the felt 411 to better resist and limit the side of the copper strip body 3 when pushed by the driving cylinder 403.

[0030] Embodiment 4: The difference between this embodiment and embodiment 1 is that the stabilizing connecting plate 416 is bent in an L-shape and is inserted into the side of the fixed connecting plate 401 .

[0031] This allows the stable connecting plate 416 to be more firmly connected to the fixed connecting plate 401 .

[0032] In this embodiment, when the copper plate and strip are milled by the milling machine, the two groups of feeders in front and behind the milling machine are pressed down by hydraulic means to press the plate, and the material is conveyed by the motor to achieve the effect of making the material milling more stable and the surface quality of the strip better. However, this type of milling will have some problems. Since the production line control method is speed control, the strip has no tension, and the distance between the milling machine and the feeders on both sides is far. When the thickness of the milling material is thin or the production line speed is fast, the amplitude generated by the equipment and the plate and strip is large, and the noise generated increases, affecting the service life of the milling cutter and the equipment body, and bringing instability and safety hazards to the production and operation of the copper plate and strip, and it will also cause the surface of the copper plate and strip to often have defects due to vibration after milling, and it will not be smooth enough.

[0033] In summary, in the specific implementation, two material pressure plate vibration damping assemblies 4 are symmetrically arranged on the upper and lower sides of the discharge port 2. When the copper plate strip body 3 is processed by the feeder 1 and sent out through the discharge port 2, it is necessary to start the two driving cylinders 403 in the material pressure plate vibration damping assembly 4. By arranging an electromagnetic valve 404 on the driving cylinder 403, the two driving cylinders 403 can be started synchronously, and the end of the driving cylinder 403 pushes the resistance connecting plate 405, so that the resistance connecting plate 405 drives the rubber pressure plate 407 to move toward the two side surfaces of the copper plate strip body 3. Since the side of the rubber pressure plate 407 is provided with felt 411, under the joint shock-absorbing action of the felt 411 and the rubber pressure plate 407, the two sides of the copper plate strip body 3 output through the discharge port 2 at high speed can be limited and resisted.

[0034] Thereby, the vibration amplitude of the copper plate strip body 3 when discharging is greatly reduced, thereby reducing the amplitude and playing a vibration reduction role, so that the milling machine is not restricted by the strip thickness and production line speed, and the equipment stability and production efficiency are better improved, so that the material can maintain a more stable operating state during milling than when it does not contain this mechanism, thereby achieving high-quality milling effect. At the same time, through the addition of the material pressure plate vibration reduction component 4, this milling method can effectively improve the equipment operation efficiency, reduce energy loss, and achieve high-speed and high-surface quality milling of high-precision copper plates.
