[0035] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0036] like Figure 1 and Figure 2 As shown, the utility model provides an embodiment of a noise reduction component applied to a cutting device, wherein the cutting device has a cutting component 2, which cuts the workpiece to be cut in a vertical direction; the noise reduction component includes a connecting member 3 and sound-absorbing cotton 4.

[0037] Among them, the connecting part 3 is located in the inner cavity of the cutting platform 1 of the cutting device, and is vertically arranged directly below the position where the cutting component 2 is located when performing the cutting action; one end of the connecting part 3 is connected to the top of the inner cavity, and the other end of the connecting part 3 is pre-buried in the ground.

[0038] The cutting component 2 generally adopts a downward pressure cutting method. The connecting part 3 can provide support for the cutting platform 1, offset the downward pressure generated by the cutting component 2, avoid vibration of the cutting platform 1, and reduce noise generation; at the same time, the connecting part 3 can guide and propagate sound waves to the interior of the surface to reduce the propagation of noise on the ground.

[0039] The connecting piece 3 adopts a round steel structure. When the sound propagates along the round steel, the energy of the sound wave will be consumed and attenuated, thereby reducing the decibel of the noise.

[0040] The sound-absorbing cotton 4 is filled in the inner cavity so that when the noise inside the cutting platform 1 propagates, the sound waves are absorbed by the sound-absorbing cotton 4, so that the noise inside the cutting platform 1 cannot propagate to the outside of the cutting platform 1, thereby reducing the generation of noise.

[0041] Furthermore, in order to meet special requirements during the cutting process, for example, when continuously transporting a workpiece to be cut, since the cutting action can no longer be completed instantly, the cutting assembly 2 needs to move synchronously with the workpiece to be cut, and the cutting is performed synchronously during the movement, the following embodiments are provided:

[0042] The cutting assembly 2 can be moved; the cutting assembly 2 is driven to move by a lead screw pair mechanism 5 , and the lead screw pair mechanism 5 is arranged on the table surface of the cutting platform 1 .

[0043] In this embodiment, a roller assembly 11 is provided on the upper surface of the cutting platform 1 above the connecting member 3, and the bottom of the cutting assembly 2 can roll in contact with the roller of the roller assembly 11 during the movement process to effectively support the cutting assembly 2 and reduce the noise generated by vibration.

[0044] In this embodiment, in order to enable the connecting member 3 to play a noise reduction role, the area where the cutting assembly 2 performs cutting action during movement is a fixed area, directly above the displacement connecting member 3, so the roller assembly 11 is also arranged in this area.

[0045] The roller assembly 11 is specifically configured as follows: the roller assembly 11 seat is set on the upper surface of the cutting platform 1, and the connecting member 3 can penetrate the cutting platform 1 and be fixed to the bottom of the roller assembly 11 seat to better guide and transmit the noise generated by cutting downward.

[0046] like Figure 3 As shown, the utility model also provides an embodiment of a light steel keel cutting machine, which is used to directly cut the light steel keels that are transported out after being machine-formed; the light steel keel cutting machine includes a cutting platform 1, a cutting component 2, a noise reduction component and a screw sub-mechanism 5.

[0047] The cutting assembly 2 is arranged on the cutting platform 1 and can move synchronously with the portion of the light steel keel to be cut. During the movement, the moving light steel keel is cut.

[0048] The screw sub-mechanism 5 is arranged on the upper surface of the cutting platform 1, and is used to drive the cutting component 2 to reciprocate along the moving direction of the light steel keel; during the cutting process, the screw sub-mechanism 5 drives the cutting component 2 to move synchronously with the part to be cut of the light steel keel. When it moves to the cutting area, the cutting component 2 performs a cutting action to cut off the light steel keel; then the screw sub-mechanism 5 drives the cutting component 2 to move in the opposite direction, return to the initial position, and wait for the next cutting cycle. After the next cutting cycle starts, the above cutting process is repeated.

[0049] The length of the cutting cycle waiting time is used to control the specific length of the light steel keel after cutting.

[0050] The noise reduction component includes a connector 3 and sound-absorbing cotton 4.

[0051] Among them, the connecting part 3 is located in the inner cavity of the cutting platform 1 of the cutting device, and is vertically arranged directly below the position where the cutting component 2 is located when performing the cutting action; one end of the connecting part 3 is connected to the top of the inner cavity, and the other end of the connecting part 3 is pre-buried in the ground.

[0052] The cutting component 2 generally adopts a downward pressure cutting method. The connecting part 3 can provide support for the cutting platform 1, offset the downward pressure generated by the cutting component 2, avoid vibration of the cutting platform 1, and reduce noise generation; at the same time, the connecting part 3 can guide and propagate sound waves to the interior of the surface to reduce the propagation of noise on the ground.

[0053] The sound-absorbing cotton 4 is filled in the inner cavity so that when the noise inside the cutting platform 1 propagates, the sound waves are absorbed by the sound-absorbing cotton 4, so that the noise inside the cutting platform 1 cannot propagate to the outside of the cutting platform 1, thereby reducing the generation of noise.

[0054] Furthermore, since the cutting assembly 2 moves synchronously with the light steel keel, in this embodiment, a roller assembly 11 is provided on the upper surface of the cutting platform 1 above the connecting member 3, and the bottom of the cutting assembly 2 can roll in contact with the roller of the roller assembly 11 during the movement process to effectively support the cutting assembly 2 and reduce the noise generated by vibration.

[0055] In order to enable the connecting member 3 to play a noise reduction role, the area where the cutting assembly 2 performs cutting action during movement is a fixed area, just above the displacement connecting member 3, so the roller assembly 11 is also arranged in this area.

[0056] The roller assembly 11 is specifically configured as follows: the roller assembly 11 seat is set on the upper surface of the cutting platform 1, and the connecting member 3 can penetrate the cutting platform 1 and be fixed to the bottom of the roller assembly 11 seat to better guide and transmit the noise generated by cutting downward.

[0057] In view of the specific process requirements of light steel keels, this embodiment provides an example of a cutting assembly 2, as shown in the figure:

[0058] The cutting assembly 2 includes a cutting mechanism 22 and a stamping mechanism 23 arranged on a movable seat 21. The screw sub-mechanism 5 drives the movable seat 21 to move; the cutting mechanism 22 is used to cut the part to be cut of the light steel keel; the stamping mechanism 23 marks the surface of the light steel keel by pressing down.

[0059] In this embodiment, the movable seat 21 is equivalent to the nut in the screw assembly 5. The movable seat 21 is threadedly connected to the screw rod 51 in the screw assembly 5; guide rods 52 are horizontally provided on both sides of the screw rod 51, and the guide rods 52 pass through the movable seat 21, and the two are slidably connected.

[0060] The roller assembly 11 is provided with multiple groups and is respectively arranged on both sides of the lead screw.

[0061] like Figure 5 As shown, the cutting mechanism 22 includes a first bracket 221 , a first hydraulic cylinder 222 and a cutting blade 223 .

[0062] There is space on the first bracket 221 for the light steel keel to pass through, and the first bracket 221 is vertically set on the movable seat 21; the first hydraulic cylinder 222 is set on the first bracket 221, and the movable end of the first hydraulic cylinder 222 faces the light steel keel; the cutting blade 223 is set at the movable end of the first hydraulic cylinder 222, and the cutting edge of the cutting blade 223 faces the light steel keel.

[0063] like Figure 6 As shown, the stamping mechanism 23 includes a second bracket 231 , a second hydraulic cylinder 232 and a stamping mold 233 .

[0064] The second bracket 231 has space for the light steel keel to pass through, and the second bracket 231 is vertically set on the movable seat 21; the second hydraulic cylinder 232 is set on the second bracket 231, and the movable end of the second hydraulic cylinder 232 is vertically downward toward the light steel keel; the steel stamp mold 233 is set at the movable end of the second hydraulic cylinder 232, and the concave and convex surface of the steel stamp mold 233 faces the light steel keel.

[0065] Furthermore, the second hydraulic cylinder 232 and the first hydraulic cylinder 222 press down in sequence. The second hydraulic cylinder 232 presses down first, pressing down and fixing the light steel keel while stamping the steel stamp. Then the first hydraulic cylinder 222 presses down again to cut the light steel keel.

[0066] Further, such as Figure 4 As shown, a support assembly is provided on the upper surface of the movable seat 21 for providing support to the light steel keel when the first hydraulic cylinder 222 and the second hydraulic cylinder 232 perform a downward pressing action.

[0067] The support assembly includes a roller group 211 composed of multiple roller groups 211. The rotation direction of the rollers in the roller group 211 is consistent with the movement direction of the light steel keel. The multiple rollers are located in the same horizontal plane, and the tops of the rollers are higher than the upper surface of the moving seat 21; the light steel keel remains parallel to the cutting platform 1 during movement, and the distance between the two allows the rollers to roll in contact with the light steel keel when the light steel keel passes through the first bracket 221 and the second bracket 231.

[0068] The roller assembly 211 supports the light steel keel while reducing the friction generated when the roller assembly 211 and the light steel keel move relative to each other (after the cutting component 2 completes the cutting, it moves in the opposite direction of the movement of the light steel keel and returns to its initial position), thereby facilitating the relative movement of the cutting component 2 and the light steel keel.

[0069] Two groups of roller assemblies 11 are respectively provided for the downward pressing areas of the first hydraulic cylinder 222 and the second hydraulic cylinder 232; each group of roller assemblies 11 is respectively provided with a group of connecting parts 3; so as to improve the stability of the entire moving base 21 during the movement and reduce noise transmission.

The scope of protection of the present application is defined by the claims. Those skilled in the art may make various modifications or equivalent substitutions to the present application within the essence and scope of protection of the present application, and such modifications or equivalent substitutions shall also be deemed to fall within the scope of protection of the present application.
