[0003] The working principle of the cutting machine is that the hydraulic cylinder drives the tool to press down instantly to cut the light steel keel; since the cutting platform of the cutting machine is a hollow structure, the top of the cutting platform will receive impact force at the moment the light steel keel is cut, just like hitting the drum surface with a drumstick, which will produce a lot of noise. In order to reduce the interference of noise and prevent the occurrence of occupational diseases, the operators on the job plug their ears with earplugs to reduce the intrusion of noise; however, in this case, since the ears of the staff are plugged with earplugs, there will be obstacles to communication between each other and there will be safety hazards.

[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 described embodiments 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 creative work are within the scope of protection of the present invention.

[0036] like Figure 1 and Figure 6 As shown, the present invention provides an embodiment of a light steel keel continuous cutting machine, which is used to directly cut the light steel keel delivered after being machine-formed; the light steel keel continuous cutting machine includes a cutting platform 1, a cutting component 2, a noise reduction component and a screw sub-mechanism 5.

[0037] The cutting assembly 2 is arranged on the cutting platform 1, and can move synchronously with the part of the light steel keel to be cut, and cut the moving light steel keel during the movement.

[0038] 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.

[0039] The length of the cutting cycle waiting time is used to control the specific length of the light steel keel after cutting.

[0040] The noise reduction component includes a connector 3 and sound-absorbing cotton 4.

[0041] Among them, the connecting member 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 member 3 is connected to the top of the inner cavity, and the other end of the connecting member 3 is pre-buried in the ground.

[0042] 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 the generation of noise; at the same time, the connecting part 3 can guide and propagate the sound waves to the inside of the surface to reduce the propagation of noise on the ground.

[0043] 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.

[0044] The sound-absorbing cotton 4 is filled in the inner cavity, so that during the propagation of the noise inside the cutting platform 1, the sound waves are absorbed by the sound-absorbing cotton 4, so that the noise inside the cutting platform 1 cannot be propagated to the outside of the cutting platform 1, thereby reducing the generation of noise.

[0045] Furthermore, since the cutting component 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 component 2 can roll in contact with the roller of the roller assembly 11 during the movement process to effectively support the cutting component 2 and reduce the noise generated by vibration.

[0046] 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, which is directly above the displacement connecting member 3. Therefore, the roller assembly 11 is also arranged in this area.

[0047] The roller assembly 11 is specifically configured as follows: the roller assembly 11 seat is arranged on the upper surface of the cutting platform 1, and the connecting member 3 can pass through the cutting platform 1 and be fixed at the bottom of the roller assembly 11 seat to better guide and transmit the noise generated by cutting downward.

[0048] In view of the specific process requirements of the light steel keel, this embodiment provides an example of the cutting component 2, such as Figure 2 and Figure 3 As shown:

[0049] The cutting assembly 2 includes a cutting mechanism 22 and a stamping mechanism 23 arranged on a moving seat 21, and the screw sub-mechanism 5 drives the moving 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.

[0050] In this embodiment, the moving seat 21 is equivalent to the nut in the screw pair mechanism 5. The moving seat 21 is threadedly connected to the screw rod 51 in the screw pair mechanism 5; guide rods 52 are horizontally arranged on both sides of the screw rod 51, and the guide rods 52 penetrate the moving seat 21, and the two are slidably connected.

[0051] The cutting mechanism 22 includes a first bracket 221 , a first hydraulic cylinder 222 and a cutting blade 223 .

[0052] There is space on the first bracket 221 for the light steel keel to pass through, and the first bracket 221 is vertically arranged on the movable seat 21; the first hydraulic cylinder 222 is arranged 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 arranged at the movable end of the first hydraulic cylinder 222, and the cutting edge of the cutting blade 223 faces the light steel keel.

[0053] The stamping mechanism 23 includes a second bracket 231 , a second hydraulic cylinder 232 and a stamping mold 233 .

[0054] 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 stamping mold 233 is set at the movable end of the second hydraulic cylinder 232, and the concave and convex surface of the steel stamping mold 233 faces the light steel keel.

[0055] 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.

[0056] Further, such as Figure 1 and Figure 6As shown, the movable seat 21 is provided with pleated curtains 24 between the two ends along its own moving direction and the ends of the corresponding cutting platform 1. As the movable seat 21 moves, the pleated curtains 24 at the two ends of the movable seat 21 are respectively expanded and contracted, which can completely cover the screw sub-mechanism 5, and prevent the waste chips generated by cutting the light steel keel and stamping from entering and falling onto the screw of the screw sub-mechanism 5, so as to avoid causing malfunction to the screw sub-mechanism.

[0057] The pleated curtain 24 can also play a role in sound insulation.

[0058] Furthermore, support frames 12 are vertically upwardly provided on both side edges of the cutting platform 1 parallel to the moving direction of the light steel keel, the support frames 12 are located inside the sound insulation cover 6, and a horizontally arranged track groove 13 is provided on the edge of the support frame 12 facing the pleated curtain 24. A plurality of pulleys 25 are evenly spaced apart on both side edges of the pleated curtain 24 facing the track groove 13. The pulley 25 is stuck in the track groove 13, and the pulley 25 can roll along the track groove 13.

[0059] The pulley 25 supports the pleated curtain 24 to prevent the pleated curtain 24 from contacting the screw of the screw sub-mechanism 5 during the movement of the moving seat 21, thereby avoiding wear on the pleated curtain 24.

[0060] The gap between the pleated curtain 24 and the cutting platform 1 is reduced to enhance the sound insulation effect.

[0061] For the downward pressing area of ​​the first hydraulic cylinder 222 and the second hydraulic cylinder 232, two groups of roller assemblies 11 are respectively provided on both sides of the screw sub-mechanism 5; 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 seat 21 during the movement process and reduce noise transmission.

[0062] Further, such as Figure 2 , Figure 3 and Figure 6 As shown, in this embodiment, the movable seat 21 is provided with two guide shafts 212 in the vertical direction between the first bracket 221 and the second bracket 231. The two guide shafts 212 can simultaneously make rolling contact with the light steel keel, restricting the movement of the light steel keel in the horizontal direction, so that the light steel keel can move in a straight line.

[0063] Specifically, the first bracket 221 and the second bracket 231 are gantry structures, and a connecting plate 214 is arranged between the two side columns of the first bracket 221 and the two side columns of the second bracket 231. The inner sides of the connecting plate 214 are provided with second spring telescopic rods 213 facing each other, and the guide shaft 212 is arranged at the end of the second spring telescopic rod 213.

[0064] Further, such as Figure 4As 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.

[0065] The supporting assembly includes a first roller group 211 composed of multiple first roller groups 211. The rotation direction of the rollers in the first roller group 211 is consistent with the moving 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.

[0066] The first roller group 211 supports the light steel keel while reducing the relative movement between the first roller group 211 and the light steel keel. After the cutting is completed, the cutting component 2 moves in the opposite direction of the moving direction of the light steel keel and returns to the initial position. The friction generated facilitates the relative movement between the cutting component 2 and the light steel keel.

[0067] like Figure 1 , Figure 5 and Figure 6 As shown, the cutting platform 1 is provided with a second roller set 14 between the side where the light steel keel enters the cutting platform 1 and the cutting assembly 2. The second roller set 14 is located above the screw pair mechanism 5 and is located in the same plane as the first roller set 211.

[0068] A first spring telescopic rod 61 is vertically downwardly provided at the top of the inner side of the soundproof cover 6 , and a guide wheel 62 is vertically downwardly provided at the movable end of the first spring telescopic rod 61 .

[0069] The guide wheel 62 and the rollers of the second roller set 14 can both be in rolling contact with the light steel keel, and restrict the movement of the light steel keel in the vertical direction, so that the light steel keel can move in a straight line.

The protection scope of the present application is defined by the claims.
