Description

Technical Field

[0001] The utility model relates to the technical field of metal parts processing, in particular to a metal parts cutting protection structure. Background Art

[0002] Metal parts cutting protection structure refers to a series of devices and structures used to ensure safety, improve cutting quality, and protect equipment during metal parts cutting operations;

[0003] During the processing of metal parts, a lot of metal debris is generated. The dust particles generated by metal cutting are usually very fine. When the operator inhales this dust, the dust will be deposited in the respiratory tract. Long-term exposure may lead to chronic respiratory diseases such as pneumoconiosis. Pneumoconiosis is an irreversible lung fibrosis disease. Patients will experience symptoms such as coughing, sputum, and difficulty breathing, which seriously affects their quality of life and work ability. Therefore, dust collection structures are usually installed on protective structures.

[0004] However, existing dust collection devices often have blind spots when dealing with dust generated by metal cutting. Especially when cutting complex metal parts, due to the variability of cutting locations and directions, it is difficult for the dust collection port to fully cover the dust-generating area. As a result, some dust cannot be sucked away in time and spreads throughout the workshop. Utility Model Content

Two connecting rods are provided, and a first transmission rod is fixedly connected to the connecting rod on the side away from the second transmission rod of the two connecting rods. The first transmission rod is fixedly connected to the rotating disk, and the first transmission rod is slidably connected to the transmission disk. The transmission disk is fixedly connected to the inner warehouse, and the transmission disk is slidably connected to the rotating disk.

[0009] The above technical solution is adopted: when in use, first install the air outlet pipe on the fan, and by providing a motor, the motor has high controllability. The motor can drive the rotating disk to rotate, and the rotating disk can drive the two second transmission rods to drive the connecting rod to move, and then drive the vertical rod and the fixed plate to drive the rubber extension plate to slide on the support frame, squeezing the air, so that the air flows out from the first filter plate from the inner bin instantly, blowing up the debris in the corner of the inner bin. After repeating several times, open the dust cover to expose the second filter screen. Then, start the fan, and the fan will blow out the debris in the inner bin to clean the debris.

[0010] As a preferred embodiment, a vent is provided on the inner bin, and the first filter plate is fixedly connected to the vent on the inner bin.

[0011] By adopting the above technical solution, the filter screen can prevent debris from escaping from the inner chamber, and the debris hanging on the filter screen can be blown out when the rubber extension plate slides through the filter screen to supply air into the inner chamber.

[0012] As a preferred embodiment, two rubber expansion plates are provided, and both of the two rubber expansion plates are slidably connected to the support frame.

[0013] The above technical solution is adopted: by providing a rubber expansion plate, the rubber expansion plate can act as a piston, so that air is squeezed out from the gap between the rubber expansion plate and the support frame, blowing up the debris in the inner bin to prevent it from accumulating in the corners of the inner bin.

[0014] As a preferred embodiment, an air inlet is opened on the inner warehouse, a second filter is fixedly connected to the air inlet on the inner warehouse, and a dust cover is fixedly connected to a side of the inner warehouse close to the second filter.

[0015] The above technical solution is adopted: the function of the second filter and the dust cover is to prevent the fan from being unable to use normally due to air blockage when the fan is transporting debris outward. The dust cover can prevent debris from escaping from the second filter when the second filter is in use.

[0016] As a preferred embodiment, a fan is fixedly connected to the bottom of the support frame.

[0017] Adopting the above technical solution: when in use, you can first connect an air pipe to the side of the inner bin close to the fan, and then blow the debris out along the air pipe.

This mechanical linkage method can generate a strong and controllable airflow to blow away the debris in the corner of the inner bin. No matter where the dust generated by the cutting of metal parts is in the inner bin of the equipment, the airflow generated by the repeated sliding of the rubber extension plate to squeeze the air can reach it, avoiding the problem of dust collection dead angles in traditional dust collection devices due to the fixed position of the dust collection port. When cutting metal parts with complex shapes, the cutting The position and direction of the dust are changeable, and the direction and position of the generated dust are difficult to predict. After the debris is blown up, the structure uses a fan to blow the debris out of the inner bin. The coordinated work of the fan and the rubber extension plate can effectively handle the dust generated under various circumstances. The first filter plate on the inner bin and the second filter screen and dust cover at the air inlet cooperate with each other to ensure the normal circulation of the airflow and prevent the escape of debris, further ensuring the cleaning of the dust generated by metal cutting, avoiding the spread of dust in the workshop, and solving the problem that the debris of the prior art in the background technology is easy to accumulate in dead corners.

[0030] 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.

[0031] like Figures 1 to 5 As shown, the metal parts cutting protection structure includes a support frame 1, and a transmission component 2 is provided on the support frame 1;

[0032] The transmission assembly 2 includes an inner bin 22, to which a first filter plate 31 is fixedly connected, an outer wall of the inner bin 22 is fixedly connected to a rubber expansion plate 21, the rubber expansion plate 21 is slidably connected to the support frame 1, a fixed plate 28 is fixedly connected to the rubber expansion plate 21, a vertical rod 29 is fixedly connected to the fixed plate 28, a connecting rod 27 is fixedly connected to the vertical rod 29, a second transmission rod 26 is rotatably connected to the connecting rod 27, a transmission disc 23 is slidably connected to the second transmission rod 26, a connecting shaft 25 is rotatably connected to the transmission disc 23, a rotating disc 210 is fixedly connected to the connecting shaft 25, the second transmission rod 26 is fixedly connected to the rotating disc 210, and a fan 4 is installed on the inner bin 22;

[0033] In the present invention, the motor 3 drives the rotating disk 210, which drives the second transmission rod 26, the connecting rod 27, the vertical rod 29 and the fixed plate 28, thereby making the rubber extension plate 21 slide on the support frame 1. This mechanical linkage method can generate a strong and controllable airflow to blow away the debris in the corners of the inner bin 22. No matter where the dust generated by the cutting of metal parts is in the inner bin 22 of the equipment, the airflow generated by the repeated sliding of the rubber extension plate 21 to squeeze the air can reach it, avoiding the problem of dust collection dead angles in traditional dust collection devices due to the fixed position of the dust collection port. When cutting pieces, the cutting position and direction are changeable, and the direction and position of the generated dust are difficult to predict. After the debris is blown up, this structure uses the fan 4 to blow the debris out of the inner bin 22. The coordinated work of the fan 4 and the rubber stretch plate 21 can effectively handle the dust generated under various circumstances. The first filter plate 31 on the inner bin 22 and the second filter screen 32 and the dust cover 33 at the air inlet cooperate with each other, which not only ensures the normal circulation of airflow, but also prevents the escape of debris, further ensures the cleaning of dust generated by metal cutting, avoids the situation where dust is diffused in the workshop, and solves the problem that debris in the prior art in the background technology is prone to accumulation in dead corners.

[0034] Further, such as Figures 1 to 5 As shown, the rotating disk 210 is fixedly connected to the motor 3, and the side of the motor 3 away from the rotating disk 210 is fixedly connected to the transmission disk 23. There are two connecting rods 27. The connecting rods 27 on the side away from the second transmission rod 26 on the two connecting rods 27 are fixedly connected to the first transmission rod 24. The first transmission rod 24 is fixedly connected to the rotating disk 210, and the first transmission rod 24 is slidably connected to the transmission disk 23. The transmission disk 23 is fixedly connected to the inner bin 22, and the transmission disk 23 is slidably connected to the rotating disk 210. When in use, the air outlet pipe is first installed on the fan 4, and the air outlet pipe is installed by setting the motor. Machine 3, the controllability of motor 3 is relatively high. Motor 3 can drive the rotating disk 210 to rotate, and the rotating disk 210 can drive the two second transmission rods 26 to drive the connecting rod 27 to move, and then drive the vertical rod 29 and the fixed plate 28 to drive the rubber extension plate 21 to slide on the support frame 1, squeezing the air, so that the air flows out from the first filter plate 31 from the inner bin 22 instantly, blowing up the debris in the corner of the inner bin 22. After repeating several times, the dust cover 33 is opened to expose the second filter screen 32. Then, the fan 4 is started, and the fan 4 blows out the debris in the inner bin 22 to clean the debris;

[0035] The inner chamber 22 is provided with a vent, and the first filter plate 31 is fixedly connected to the vent on the inner chamber 22. The filter screen can prevent debris from escaping from the inner chamber 22. When the rubber expansion plate 21 slides through the filter screen to supply air into the inner chamber 22, the debris hanging on the filter screen can be blown out.

[0036] Two rubber expansion plates 21 are provided, and both rubber expansion plates 21 are slidably connected to the support frame 1. The rubber expansion plates 21 can act as pistons, so that air is squeezed out from the gap between the rubber expansion plates 21 and the support frame 1, blowing away the debris in the inner bin 22 to prevent it from accumulating in the corners of the inner bin 22;

[0037] The above solution still has the problem that the air inlet of the fan 4 is not provided during use, and the fan 4 cannot work normally. Figures 1 to 5 As shown, an air inlet is opened on the inner bin 22, and a second filter 32 is fixedly connected to the air inlet on the inner bin 22. A dust cover 33 is fixedly connected to the side of the inner bin 22 close to the second filter 32. The second filter 32 and the dust cover 33 are used to prevent the fan 4 from being unable to operate normally due to air obstruction when the fan 4 is transporting debris outward. The dust cover can prevent debris from escaping from the second filter 32 when the second filter 32 is in use.

[0038] The bottom of the support frame 1 is fixedly connected to a fan 4. When in use, an air pipe can be first connected to the side of the inner bin 22 close to the fan 4, and the air cylinder fan 4 can be used to blow out the debris along the air pipe.

[0039] Working principle: Figures 1 to 5 As shown, when in use, first, the air outlet pipe must be installed on the fan 4, and the motor 3 must be started. When the motor 3 is started, the rotating disk 210 is driven to rotate. The rotating disk 210 is connected to the two second transmission rods 26. When the rotating disk 210 rotates, the two second transmission rods 26 are driven to move. The second transmission rods 26 then drive the connecting rod 27 to move. The connecting rod 27 then drives the vertical rod 29 and the fixed plate 28 to move, and finally the rubber expansion plate 21 slides on the support frame 1.

[0040] Because there are two rubber expansion plates 21, when they slide on the support frame 1, they act like pistons, squeezing the air so that the air enters the inner chamber 22 from the first filter plate 31, thereby blowing away the debris in the corners of the inner chamber 22. This operation can be repeated to ensure that all the debris in the corners is blown away.

[0041] After the debris blowing operation is completed, an air inlet is opened on the inner bin 22, and a second filter screen 32 is fixed at the air inlet and a dust cover 33 is fixed on the side close to the second filter screen 32 to ensure normal air circulation when the fan 4 is working and prevent debris from escaping from the second filter screen 32. After opening the dust cover 33 to expose the second filter screen 32, the fan 4 installed at the bottom of the support frame 1 is started. The fan 4 forms an airflow in the inner bin 22, and blows the previously blown debris out of the inner bin 22 through the air pipe to achieve debris cleaning. At the same time, the first filter plate 31 can prevent debris from escaping from the vent of the inner bin 22, and can blow out the debris hanging on the filter screen when the rubber expansion plate 21 slides to supply air to the inner bin 22.

[0042] The above description is merely a preferred embodiment of the present invention and does not constitute any form of limitation to the present invention. Although the present invention has been disclosed as above with preferred embodiments, it is not intended to limit the present invention. Any technician familiar with this patent can make some changes or modifications to equivalent embodiments with equivalent changes using the above-mentioned technical contents without departing from the scope of the technical solution of the present invention. The implementation schemes in the above embodiments can also be further combined or replaced. However, any simple modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention without departing from the content of the technical solution of the present invention are still within the scope of the solution of the present invention.
