Description

Technical Field

[0001] The invention belongs to the technical field of grinding wheel cutting machines, and in particular relates to a grinding wheel cutting machine for cutting metal pipes at construction sites. Background Art

[0002] During construction, building materials are often needed. Common building materials include iron plates, steel plates, wood, angle irons, steel pipes, etc. Before using metal pipes, people need to cut them to a suitable length so that they can become suitable and usable building materials. At present, people use grinding wheel cutters to cut metal pipes. The existing grinding wheel cutters drive the grinding wheel to rotate at high speed through the driving motor, and the staff pushes the high-speed rotating grinding wheel down to achieve the cutting of the metal pipe.

[0003] However, the existing grinding wheel cutters still have some defects during use: first, during the cutting process, a large amount of debris will be generated when the grinding wheel contacts the workpiece. The splashing of debris may cause skin burns to the workers, posing a safety hazard, and also cause the debris to be scattered on the workbench, which is difficult to collect; second, the existing grinding wheel cutters only fix the cut workpiece by using one plate to support the workpiece against another plate and fix it on the workbench by clamping. The clamping is not stable enough. During the cutting process, one end of the workpiece may lose balance and tilt up due to the downward pressure of the grinding wheel or cutting, which is not convenient for cutting and may cause danger to the workers due to the sudden tilting. Summary of the invention

[0004] The present application proposes an abrasive wheel cutting machine for cutting metal pipes at construction sites, which has the advantages of effectively blocking and collecting flying debris and enhancing the clamping stability of the workpiece, so as to solve the safety hazards caused by flying debris and work activities.

The other end of the transmission device 23 movably passes through the other end of the adjusting device 22 and is movably connected to the grinding wheel 25. The driving motor 24 and the grinding wheel 25 are connected by the transmission device 23, so that when the driving motor 24 is started, the grinding wheel 25 can be driven to rotate at a high speed, thereby realizing that the grinding wheel 25 cuts the workpiece 10. The grinding wheel 25 is located at The upper middle part of the working groove is located above the working groove, thereby ensuring that the setting of the protection mechanism 3 will not affect the normal operation of the grinding wheel 25. The grinding wheel cover 26 is movably connected to the adjusting device 22 which is movably sleeved with the transmission device 23, and the interior of the grinding wheel cover 26 is movably sleeved with the upper half of the grinding wheel 25, which can not only protect the grinding wheel 25 but also reduce the splash of debris. The handle 27 is movably connected to the adjusting device 22, and the staff can push the handle 27 to achieve the downward and upward pressing of the grinding wheel 25. In summary, when cutting, start the driving motor 24, so that the transmission device 23 drives the grinding wheel 25 to rotate at a high speed, and then the staff holds the handle 27 to drive the downward pressing and upward pushing of the grinding wheel 25 to achieve the cutting of the workpiece 10.

Since the main working position of the grinding wheel 25 is above the working groove, the height setting of the protection mechanism 3 is convenient for blocking and collecting the debris above the working groove. The protection mechanism 3 includes a first baffle 31, a first baffle frame 32, a second baffle frame 33 and a second baffle 34. Fig.13 The first baffle plate 31 and the second baffle plate 34 are in the shape of a flat plate, and the first baffle frame 32 and the second baffle frame 33 are in the shape of a flat frame, so that the protection mechanism 3 composed of the first baffle plate 31, the first baffle frame 32, the second baffle frame 33 and the second baffle plate 34 can fully block the flying debris, and the debris is collected in the protection mechanism 3 without escaping, one side of the first baffle plate 31 is fixedly connected to the inner wall of the working groove of the workbench 1, and the other side of the first baffle plate 31 is fixedly connected to one side of the first baffle frame 32, the other side of the first baffle frame 32 is movably connected to one side of the second baffle frame 33, and the other side of the second baffle frame 33 is fixedly connected to one side of the second baffle plate 34, as shown in FIG. Fig.14One side of the inner bottom end of the first baffle frame 32 is an inclined surface, and the inclined surface of the first baffle frame 32 is close to the second baffle plate 34, so that the first baffle frame 32 can shovel up the debris at the inner bottom end of the second baffle frame 33 when the second baffle frame 33 moves, preventing the debris from affecting the telescopic deformation of the protection mechanism 3. Pushing the second baffle frame 33 and the second baffle plate 34 can change the length of the protection mechanism 3, thereby realizing the function of the protection mechanism 3 in different states. Specifically, the compressed protection mechanism 3 can effectively block the flying debris and collect the debris while ensuring the normal operation of the grinding wheel 25. The protection mechanism 3 when extended can effectively collect the debris left in the working groove, further improving the convenience of debris collection and reducing the impact of debris on subsequent work. Embodiment 2

The movable rope 42 can be used to control the synchronous rotation of several movable plates 41. Specifically, when the first baffle plate 31 and the second baffle plate 31 are When the distance between the baffles 34 decreases, the required lateral distance of the movable rope 42 decreases and the vertical distance of the movable rope 42 is extended, so that the movable plate 41 is tilted inward and downward under the action of its own gravity, so that the flying debris can pass through the movable plate 41 obliquely downward into the protection mechanism 3, and effectively reduce the possibility of the debris collected in the protection mechanism 3 escaping. When the distance between the first baffle 31 and the second baffle 34 increases, the required lateral distance of the movable rope 42 increases and the vertical distance of the movable rope 42 decreases, so that the movable plate 41 is tilted inward and upward under the action of the pulling force of the movable rope 42, so that the movable hole near the bottom of the working groove is fully opened to further collect the scattered debris in the working groove. Embodiment 3

[0025] On the basis of the second embodiment, a grinding wheel cutting machine for cutting metal pipes at a construction site further comprises: like Figure 1 , Figure 3-Figure 9 , a clamping mechanism 5, a clamping mechanism 5 is arranged at the top of the workbench 1, and the clamping mechanism 5 is not located above the working groove, a clamping mechanism 5 is arranged in the middle of one side of the two protection mechanisms 3, and the two clamping mechanisms 5 are symmetrically arranged for clamping and fixing the workpiece 10, the clamping mechanism 5 includes a clamping member 51 and a fixing assembly 6, as shown Figure 6-Figure 7 The shape of the clamping member 51 is an inverted "U" shape. The bottom end of the clamping member 51 is fixedly connected to the top end of the workbench 1, and the workpiece 10 is movably sleeved inside the clamping member 51. The workpiece 10 passes through the two clamping members 51 at the same time, thereby providing conditions for the stable setting of both ends of the workpiece 10 during cutting.

[0026] like Figure 1 , Figure 3-Figure 9 The fixing assembly 6 is provided inside the clamping member 51, and the fixing assembly 6 is located inside the clamping member 51 near the protection mechanism 3, and is used to clamp and fix the workpiece 10 to enhance the stability of the workpiece 10. The fixing assembly 6 includes a fixing rod 61, a fixing arc plate 62 and a fixing handle 63, as shown in FIG. Fig. 9 The outer wall of the fixing rod 61 is provided with a threaded groove, and the fixing rod 61 is threadedly sleeved with the clamping member 51 through the threaded groove, the bottom end of the fixing rod 61 is threadedly connected with the top end of the fixing arc plate 62, and the bottom end of the fixing arc plate 62 is in contact with the middle top of the workpiece 10. When the workpiece 10 needs to be clamped, the fixing rod 61 is first inserted into the clamping member 51, and then the fixing arc plate 62 is threadedly fixed on the fixing rod 61, and then the fixing rod 61 is rotated and moved downward until the fixing arc plate 62 is in contact with the workpiece 10, and the workpiece 10 is clamped and fixed. When the workpiece 10 needs to be disassembled, the fixing rod 61 is first rotated and moved upward, and then the fixing arc plate 62 is removed, and then the fixing rod 61 is continuously rotated until the fixing rod 61 is disengaged from the clamping member 51. The top end of the fixing rod 61 is fixedly connected with a fixing handle 63, and the fixing handle 63 is located above the clamping member 51, and the fixing handle 63 can be rotated to realize the up and down movement of the fixing rod 61. Embodiment 4

[0027] On the basis of the third embodiment, the clamping mechanism 5 further includes: like Figure 1 , Figure 3-Figure 9 , Figure 15-16 The limiting assembly 7 is fixedly arranged inside the clamping member 51 on both sides of the workpiece 10, and the limiting assembly 7 is located inside the clamping member 51 away from the protection mechanism 3, and is used to further limit and fix the workpiece 10 and enhance the stability of the workpiece 10. The limiting assembly 7 includes a main limiting bag 71, a first auxiliary bag 72 and a second auxiliary bag 73, such as Figure 5 , Figure 8 , Fig.16The interior of the clamping member 51 is fixedly connected with a main limiting capsule 71, and the main limiting capsule 71 is filled with a solution. The solution in the main limiting capsule 71 is the condition for the deformation of the first auxiliary capsule 72 and the second auxiliary capsule 73. The wall of the main limiting capsule 71 close to the protection mechanism 3 is fixedly connected with the first auxiliary capsule 72, and the first auxiliary capsule 72 is movably connected with the clamping member 51. The number of the first auxiliary capsules 72 is several, and the first auxiliary capsules 72 are vertically arranged on the clamping member 51. The wall of the main limiting capsule 71 close to the workpiece 10 is fixedly connected with the second auxiliary capsule 73, and the second auxiliary capsule 73 is movably connected with the clamping member 51. The number of the second auxiliary capsules 73 is several, and the second auxiliary capsules 73 are vertically arranged on the clamping member 51, so that The outer wall of the workpiece 10 is fully wrapped to achieve limited clamping of the workpiece 10. The first auxiliary bag 72 and the second auxiliary bag 73 are both elastic, and the contraction elasticity of the second auxiliary bag 73 is greater than that of the first auxiliary bag 72. When the first auxiliary bag 72 is compressed by external force, the second auxiliary bag 73 is pushed to expand due to the movement of the solution, so that the second auxiliary bag 73 extends outward to the outside of the clamping member 51 and effectively limits the clamping of the workpiece 10. When the first auxiliary bag 72 is stretched by external force, the thrust of the solution on the second auxiliary bag 73 is reduced, and the second auxiliary bag 73 retracts into the inside of the clamping member 51 under the action of its own contraction elasticity, thereby not clamping the workpiece 10, facilitating the next processing of the workpiece 10.

[0028] The protection mechanism 3 also includes: like Figure 4-Figure 5 , Fig.13 , an insert plate 8, one end of the insert plate 8 is fixedly connected to the middle part of the top end of the second baffle 34, the other end of the insert plate 8 passes through the first baffle 31 and is movably sleeved with the middle part of the top end of the clamp 51, a threaded hole is opened on the insert plate 8, and the insert plate 8 can be threadedly sleeved with the fixing component 6 through the threaded hole. By connecting the fixing component 6 and the insert plate 8, the protection mechanism 3 can be in a compressed state, effectively ensuring the stability of the protection mechanism 3 during cutting.

[0029] like Fig.13 , Figure 15-16 , an insertion rod 9, one end of the insertion rod 9 is fixedly connected to the wall surface of the second baffle plate 34, and the insertion rod 9 corresponds to the second auxiliary bag 73 one by one, the other end of the insertion rod 9 passes through the first baffle plate 31 and is fixedly connected to the first auxiliary bag 72, a transverse spring is arranged between the first baffle plate 31 and the second baffle plate 34, and the transverse spring is movably sleeved with the outside of the insertion rod 9. When the protection mechanism 3 is compressed, the transverse spring is compressed. At this time, the insertion rod 9 can push the first auxiliary bag 72 to compress, thereby realizing the expansion and stretching of the second auxiliary bag 73. When the protection mechanism 3 is stretched, the transverse spring is stretched. At this time, the insertion rod 9 can drive the first auxiliary bag 72 to stretch, thereby realizing the deformation and shrinkage of the second auxiliary bag 73.

[0030] The working principle of the method of the present invention is as follows: When the workpiece 10 needs to be cut, the workpiece 10 is first placed on the top of the workbench 1, and the workpiece 10 passes through the two protection mechanisms 3 and the two clamping mechanisms 5, and then the two protection mechanisms 3 are pushed to compress, that is, the second baffle 34 is pushed to move toward the first baffle 31, and the insert plate 8 is sleeved on the clamping member 51, and then the fixing assembly 6 is installed, that is, the lower end of the fixing rod 61 is rotated and inserted into the clamping member 51 sleeved with the insert plate 8, and the lower end of the fixing rod 61 is threadedly connected with the fixing arc plate 62 after passing through the clamping member 51, and then the fixing rod 61 is continuously rotated and moved downward until the fixed arc plate 62 clamps and fixes the top of the workpiece 10, thereby The fixing assembly 6 is used to fix and clamp the two ends of the workpiece 10 to prevent one end of the workpiece 10 from losing balance and tilting up during the cutting process, thereby posing a danger to the staff. In this process, the movement of the second baffle 34 synchronously drives the insertion rod 9 to move, so that the insertion rod 9 effectively squeezes the first auxiliary bag 72 to expand the second auxiliary bag 73, so that the second auxiliary bag 73 is fitted with the workpiece 10. The second auxiliary bag 73 is used to push and adjust the position of the workpiece 10 so that the workpiece 10 is located directly below the fixing assembly 6, further ensuring the clamping stability of the workpiece 10 by the fixing assembly 6, and limiting and fixing the outer wall of the workpiece 10, thereby further improving the stability of the setting of the workpiece 10.

[0031] When the workpiece 10 is cut, the staff controls the cutting mechanism 2 to move, so that the grinding wheel 25 is pressed down and the workpiece 10 is cut. Since the side of the workpiece 10 being cut is provided with a protective mechanism 3, the generated debris will be blocked by the two protective mechanisms 3 and will not fly to the staff on the side of the grinding wheel 25, thereby effectively improving the safety of the staff. At the same time, the protective mechanism 3 can fully collect the splashing debris when blocking. In this process, after the protective mechanism 3 is compressed, the movable plate 41 is affected by the movable rope 42 and is tilted inward and downward, so that the movable hole of the second baffle 34 is opened obliquely upward, which allows the splashing debris to pass through the movable plate 41 into the protective mechanism 3 to realize the collection of debris, and effectively reduces the possibility of the debris collected in the protective mechanism 3 escaping from its bottom.

[0032] When the cutting is completed, the fixing assembly 6 is removed from the clamping member 51, and the workpiece 10 can be taken out. At the same time, the two second baffles 34 are pushed toward the middle of the working groove, so that the protection mechanism 3 extends, effectively collecting the debris left in the working groove.
