Description

Technical Field

[0001] This application relates to the technical field of pipe cutting, and in particular to a lifting blade cutting machine. Background Technology

[0002] After the pipes are formed, they are usually quite long; therefore, cutting equipment is used to cut the pipes to the required length.

[0003] Currently, Chinese patent CN205466423U discloses a blade-lifting cutting machine. This machine includes a frame with a cutting table. A drive shaft mounting plate is hinged to the frame, and a saw blade mounting shaft is mounted on the drive shaft mounting plate. The drive shaft mounting plate is fixed to the frame by a blade-lifting cylinder. A motor mounting plate is hinged below the drive shaft mounting plate, and a drive motor is mounted on the motor mounting plate. The drive motor is connected to the saw blade mounting shaft for transmission. An angle adjustment and locking mechanism is provided between the motor mounting plate and the drive shaft mounting plate. When the drive motor starts, the saw blade mounting shaft rotates at high speed, which in turn causes the saw blade to rotate at high speed. The blade-lifting cylinder retracts, lifting the blade and allowing the saw blade to pass over the material to be cut, thus achieving the cutting action.

[0004] When a saw disc cuts pipes, it produces debris. The saw teeth on the disc move in a circular motion, so the debris flies everywhere along the tangent of the teeth, causing environmental pollution. Summary of the Invention

[0005] In order to reduce environmental pollution, this application provides a lifting blade cutting machine.

[0006] This application provides a lifting blade cutting machine, which adopts the following technical solution: A lifting-blade cutting machine includes a frame, a processing table, a fixed base, a cutting saw blade, a lifting and rotating mechanism, and a slag suction mechanism. The processing table is mounted on the frame and has a receiving cavity. A first through hole communicating with the receiving cavity is also provided on the processing table. The fixed base is mounted on the processing table and covers the first through hole. A second through hole for pipes to pass through is provided on the fixed base, and a collection cavity communicating with the second through hole is also provided on the fixed base. Both the second through hole and the collection cavity are connected to the first through hole. The cutting saw blade is connected to the processing table via the lifting and rotating mechanism. The cutting saw blade is located within the receiving cavity, and a portion of the cutting saw blade can enter the second through hole and the collection cavity through the first through hole. The slag suction mechanism is mounted on the frame, and both the receiving cavity and the collection cavity are connected to the slag suction mechanism. The slag suction mechanism can absorb debris located in the collection cavity and the receiving cavity.

[0007] By adopting the above technical solution, the pipe is first passed through the second through hole on the fixed base, aligning the pipe to be cut with the cutting saw blade. Then, the lifting and rotating mechanism is activated. While driving the cutting saw blade to rotate, the lifting and rotating mechanism also drives the cutting saw blade to move vertically, allowing it to pass through the first through hole and cut the pipe located in the second through hole. The debris generated by the cutting saw blade enters the collection chamber. The slag suction mechanism is then activated, creating negative pressure in the receiving and collecting chambers. Under this negative pressure, the debris is collected in the collecting and receiving chambers and then uniformly recycled for reuse. Therefore, the lifting blade cutting machine of this application can collect the debris generated during pipe cutting, thereby reducing environmental pollution. Furthermore, the collected debris facilitates subsequent recycling. The direct collection of debris by the slag suction mechanism also reduces the risk of foreign objects such as iron pieces entering the debris during cleaning, thus affecting its recycling.

[0008] Optionally, the slag suction mechanism includes a first suction pipe, a second suction pipe, and a negative pressure collection assembly, wherein the negative pressure collection assembly is disposed on one side of the frame; one end of the first suction pipe is connected to the negative pressure collection assembly, and the end of the first suction pipe away from the negative pressure collection assembly is connected to the processing table and communicates with the receiving cavity; one end of the second suction pipe is connected to the first suction pipe, and the end of the second suction pipe away from the first suction pipe is connected to the fixed base and communicates with the collection cavity.

[0009] By adopting the above technical solution, when the cutting saw blade cuts the pipe located in the second through hole, the negative pressure collection component is activated. Part of the debris generated by cutting will enter the collection chamber and then enter the first suction pipe through the second suction pipe; another part of the debris will enter the receiving chamber through the first through hole, then enter the first suction pipe, and finally enter the negative pressure collection component.

[0010] Optionally, both sides of the fixing seat are provided with communicating cavities that communicate with the second through hole. The fixing seat is provided with a pressing component, which includes an adjusting cylinder and a pressing block. The adjusting cylinder is disposed on the fixing seat, and the pressing block is located in the communicating cavity and connected to the piston rod of the adjusting cylinder.

[0011] By adopting the above technical solution, when the pipe is located in the second through hole of the fixed seat, the adjusting cylinder is activated. The piston rod of the adjusting cylinder drives the clamping block to move towards the pipe, so that the clamping block presses against the pipe and restricts the pipe on the fixed seat. This reduces the shaking of the pipe when the cutting saw blade cuts the pipe, thereby improving the stability of the pipe on the fixed table.

[0012] Optionally, the fixing seat is provided with a sealing assembly, which includes a sealing strip and a connector. The sealing strip abuts against the side wall of the communicating cavity near the collecting cavity; the connector connects the sealing strip and the side wall of the communicating cavity.

[0013] By adopting the above technical solution, the sealing strip can abut against the pipe when the pipe is located in the second through hole, so that the cutting debris can better enter the collection cavity and the receiving cavity.

[0014] Optionally, the lifting and rotating mechanism includes a support block, a drive shaft, a blocking plate, a drive assembly, and a lifting assembly. The support block is slidably mounted on the processing table via the lifting assembly. A third through hole communicating with the receiving cavity is provided on the processing table. The drive shaft is rotatably mounted on the support block, with one end of the drive shaft passing through the third through hole and located inside the receiving cavity. The cutting saw blade is mounted on the drive shaft. The blocking plate is mounted on the end of the drive shaft located inside the receiving cavity and covers the third through hole. The drive assembly is mounted on the support block and connected to the drive shaft.

[0015] By adopting the above technical solution, when it is necessary to cut the pipe located in the second through hole, the drive assembly is first started, which drives the drive shaft to rotate, causing the cutting saw blade on the drive shaft to rotate; then the lifting assembly is started, which drives the support block to move, and the drive shaft on the support block will drive the rotating cutting saw blade to rise and fall, so that the cutting saw blade can pass through the first through hole on the processing table to cut the pipe located in the second through hole.

[0016] Optionally, a cleaning mechanism is provided on the processing table. The cleaning mechanism includes a rotating shaft, an adjusting block, cleaning brush blocks, a first adjusting component, and a second adjusting component. The rotating shaft is rotatably mounted on the processing table and located within the receiving cavity. The adjusting block is mounted on the rotating shaft. Multiple cleaning brush blocks are provided, and all of the multiple cleaning brush blocks are slidably mounted on the adjusting block. The first adjusting component is mounted on the processing table, and both the rotating shaft and the supporting block are connected to the first adjusting component. The second adjusting component is mounted on the adjusting block, and all of the multiple cleaning brush blocks are connected to the second adjusting component.

[0017] By adopting the above technical solution, when the cutting saw blade cuts the pipe, some debris will adhere to the cutting saw blade. At this time, the lifting component drives the support block to move downward, so that the cutting saw blade moves downward in the receiving cavity. Then, the first adjustment component on the support block will drive the rotating shaft to rotate, and the rotating shaft will drive the adjustment block to move closer to the cutting saw blade, so that the cleaning brush block on the adjustment block will come into contact with the cutting saw blade. Then, the second adjustment component is activated, which drives multiple cleaning brushes to move quickly. The multiple cleaning brushes can clean the cutting saw blade, thereby reducing the debris adhering to the cutting saw blade and affecting its use.

[0018] Optionally, the first adjustment assembly includes an adjustment rack, an adjustment shaft, an adjustment gear, a protective block, a first bevel gear, and a second bevel gear. The adjustment rack is disposed on the support block. The adjustment shaft is rotatably disposed on the machining table. The adjustment gear is keyed to the adjustment shaft and meshes with the adjustment rack. The protective block is disposed on the machining table and located within the receiving cavity. A cavity is formed on the protective block. One end of the adjustment shaft away from the adjustment gear is located within the cavity. A portion of the rotating shaft is located within the cavity. The first bevel gear is keyed to the adjustment shaft and located within the cavity. The second bevel gear is keyed to the rotating shaft located within the cavity, and the second bevel gear meshes with the first bevel gear.

[0019] By adopting the above technical solution, when the lifting block drives the drive shaft to move, the adjusting rack on the lifting block drives the adjusting gear to rotate, the adjusting gear drives the adjusting shaft to rotate, the first bevel gear on the adjusting shaft drives the second bevel gear to rotate, the second bevel gear drives the rotating shaft to rotate, and the rotating shaft drives the adjusting block to move; the protective block can reduce the entry of debris between the meshing first bevel gear and the second bevel gear.

[0020] Optionally, the adjusting block has an adjusting cavity, and the adjusting block has multiple adjusting slots communicating with the adjusting cavity. Each adjusting slot corresponds to a cleaning brush block, and the cleaning brush block covers the adjusting slot. The second adjusting assembly includes an adjusting motor, an adjusting disk, and a movable block. The adjusting motor is mounted on the adjusting block, and the adjusting disk is mounted on the output shaft of the adjusting motor and located within the adjusting cavity. The adjusting disk has multiple driving slots, each corresponding to a adjusting slot. One end of the movable block is slidably disposed within the driving slot, and the end of the movable block away from the driving slot passes through the adjusting slot and connects to the cleaning brush block.

[0021] By adopting the above technical solution, the adjustment motor is started, and the output shaft of the adjustment motor drives the adjustment plate to rotate. The drive groove on the adjustment plate drives the movable block to move. Under the restriction of the adjustment groove, the movable block can move in the adjustment groove. The movable block drives the cleaning brush block to move, so that the cleaning brush block cleans the cutting saw blade. The second adjustment component, which is equivalent to the iris structure, can move synchronously in multiple cleaning brush blocks, so that the cleaning brush blocks clean the cutting saw blade.

[0022] Optionally, the processing table is slidably mounted on the frame, and a follower cylinder is mounted on the frame. The cylinder body of the follower cylinder is mounted on the frame, and the piston rod is connected to the processing table.

[0023] By adopting the above technical solution, the set follow-up cylinder can make the processing table move. When the cutting saw blade on the processing table cuts the pipe, the processing table moves synchronously with the pipe. After the cutting is completed, the processing table moves to the position where the pipe needs to be cut again. In this way, the pipe can always keep moving, thereby reducing the phenomenon of the pipe not moving during cutting and then adjusting the pipe after cutting, thus improving the efficiency of pipe cutting.

[0024] Optionally, the processing table is provided with two guiding and limiting mechanisms, and the fixing seat is located between the two guiding and limiting mechanisms. Each guiding and limiting mechanism includes a guiding and limiting block and a fixing member. The guiding and limiting block is connected to the processing table through the fixing member. There are two guiding and limiting blocks, and the two guiding and limiting blocks form a guiding and limiting space, which communicates with the second through hole.

[0025] By adopting the above technical solution, the guide limiting block is fixed on the processing table by the fastener, so that the two guide limiting blocks form a guide limiting space that communicates with the second through hole; the pipe to be cut can enter the second through hole of the fixed seat through the guide limiting space.

[0026] In summary, this application includes at least one of the following beneficial technical effects: 1. The lifting blade cutting machine of this application can collect the generated debris when cutting pipes, thereby reducing environmental pollution; the collected debris can be easily recycled; and the direct collection of the cutting debris by the slag suction mechanism can also reduce the possibility of other foreign objects such as iron pieces entering the debris and affecting the recycling of the debris when the operator cleans and collects the debris. 2. The cleaning mechanism can clean the cutting saw blade, thereby reducing the debris adhering to the cutting saw blade and affecting its use. Attached Figure Description

[0037] When the lifting cylinder 254 is activated, the piston rod of the lifting cylinder 254 drives the lifting block 253 to move, and the slider 252 on the lifting block 253 slides on the guide block 251. When the lifting block 253 moves, it drives the support block 21 to move. The drive shaft 22 on the support block 21 drives the cutting saw blade 14 to rotate, so that a part of the cutting saw blade 14 can pass through the first through hole 122 on the processing table 12. When the support block 21 drives the drive shaft 22 to move, the baffle plate 23 on the drive shaft 22 always keeps the third through hole 123 sealed.

One end of the adjustment shaft 642 is located outside the processing table 12, and an adjustment gear 643 is keyed to the adjustment shaft 642 located outside the processing table 12. An adjustment rack 641 that meshes with the adjustment gear 643 is fixedly connected to the support block 21.

[0053] A protective block 644 is fixedly connected to the processing table 12. A cavity is opened in the protective block 644. The rotating shaft 61 passes through the protective block 644 and part of it is located in the cavity. A second bevel gear 646 is keyed to the rotating shaft 61 located in the cavity. The end of the adjusting shaft 642 away from the adjusting gear 643 is located in the cavity of the protective block 644. A first bevel gear 645 that meshes with the second bevel gear 646 is keyed to the adjusting shaft 642 located in the cavity.

[0054] When the drive shaft 22 on the support block 21 drives the cutting saw blade 14 to move downwards, the adjusting rack 641 on the support block 21 drives the adjusting gear 643 to rotate, the adjusting gear 643 drives the adjusting shaft 642 to rotate, the adjusting shaft 642 drives the first bevel gear 645 to rotate, the first bevel gear 645 drives the second bevel gear 646 to rotate, the second bevel gear 646 drives the rotating shaft 61 to rotate, and the rotating shaft 61 drives the adjusting block 62 to rotate, so that the cleaning brush block 63 on the adjusting block 62 abuts against the cutting saw blade 14.

[0055] refer to Figure 7 and Figure 8 The adjusting block 62 has an adjusting cavity, and the adjusting block 62 has multiple adjusting grooves 621 that communicate with the adjusting cavity. The adjusting grooves 621 are arc-shaped. The number of adjusting grooves 621 is the same as the number of cleaning brush blocks 63. The cleaning brush blocks 63 correspond one-to-one with the adjusting grooves 621, and the cleaning brush blocks 63 cover the adjusting grooves 621.

[0056] A second adjustment component 65 is provided on the adjustment block 62. The second adjustment component 65 includes an adjustment motor 651 fixedly connected to the adjustment block 62. An adjustment disk 652 is fixedly connected to the output shaft of the adjustment motor 651 and is located in the adjustment cavity of the adjustment block 62. The adjustment disk 652 has multiple drive slots 6521, the number of which is the same as the number of adjustment slots 621, and the drive shaft 22 corresponds one-to-one with the adjustment slots 621. A movable block 653 is slidably connected in the drive slot 6521. The end of the movable block 653 away from the adjustment disk 652 passes through the adjustment slot 621 and is fixedly connected to the cleaning brush block 63.

[0057] Start the adjustment motor 651. The output shaft of the adjustment motor 651 drives the adjustment plate 652 to rotate. The drive groove 6521 on the adjustment plate 652 drives the movable block 653 to move. Under the restriction of the adjustment groove 621, the movable block 653 can move within the adjustment groove 621. The movable block 653 drives the cleaning brush block 63 to move, so that the cleaning brush block 63 cleans the cutting saw blade 14.

[0058] The implementation principle of Embodiment 2 of this application is as follows: Initially, the cutting saw blade 14 is initially located in the receiving cavity 121. The drive shaft 22 on the support block 21 drives the cutting saw blade 14 to move upward and pass through the first through hole 122 to cut the pipe located in the second through hole 131. After that, it returns to this initial position. When the cutting saw blade 14 is in the initial position, there is a certain distance between the cleaning brush block 63 and the cutting saw blade 14.

[0059] After the cutting saw blade 14 has been used for a period of time, the lifting cylinder 254 is activated, causing the drive shaft 22 on the support block 21 to move the cutting saw blade 14 downwards from the initial position in the receiving cavity 121. The adjusting rack 641 on the support block 21 drives the adjusting gear 643 to rotate, the adjusting gear 643 drives the adjusting shaft 642 to rotate, the adjusting shaft 642 drives the first bevel gear 645 to rotate, the first bevel gear 645 drives the second bevel gear 646 to rotate, the second bevel gear 646 drives the rotating shaft 61 to rotate, and the rotating shaft 61 drives the adjusting block 62 to rotate, causing the cleaning brush block 63 on the adjusting block 62 to abut against the cutting saw blade 14. Then, the adjustment motor 651 is started. The output shaft of the adjustment motor 651 drives the adjustment plate 652 to rotate. The drive groove 6521 on the adjustment plate 652 drives the movable block 653 to move. Under the restriction of the adjustment groove 621, the movable block 653 can move in the arc-shaped adjustment groove 621. The movable block 653 drives the cleaning brush block 63 to move, so that the cleaning brush block 63 cleans the cutting saw blade 14 and removes the debris attached to the side wall of the cutting saw blade 14 and between the saw teeth of the cutting saw blade 14.

[0060] Because the number of cleaning brush blocks 63 is less than the number of saw teeth in the cutting saw blade 14, the adjusting motor 651 can be started first to restore the cleaning brush blocks 63 to their initial position; then the lifting cylinder 254 can be started to drive the drive shaft 22 on the support block 21 to move the cutting saw blade 14 upward in the receiving cavity 121 and restore it to its initial position, so that the cleaning brush blocks 63 on the adjusting block 62 no longer resist the cutting saw blade 14. Next, the drive motor 241 can be started to rotate the cutting saw blade 14 at a certain angle; then the lifting cylinder 254 and the adjusting motor 651 can be started again to clean the cutting saw blade 14 with the cleaning brush blocks 63.

[0061] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
