TECHNICAL FIELD

[0001] The present application relates to the technical field of band sawing machine, in particular to a high-performance sawing device for joint raw materials. BACKGROUND

[0002] The horizontal band sawing machine as a kind of efficient and accurate metal processing equipment occupies an important position in modern manufacturing. The horizontal band sawing machine gradually occupies a place in the field of metal processing with its compact structure, convenient operation and high processing efficiency; the common band sawing machine is usually driven by a driving wheel and a driven wheel to run the band saw, and the band saw is twisted by a guide wheel to a certain angle, so that the working area of the band saw is perpendicular to the processing platform.

[0003] The existing horizontal band sawing machine is lubricated and cooled in the same way as the ordinary cutting machine, that is, the lubricating liquid is poured directly on the saw blade and the raw material sawing place by a pipe, and the lubricating liquid flows to the bottom of the saw blade and the raw material sawing place. However, sawing is different from ordinary cutting, and the saw blade contacts and scrapes the raw material during sawing. As the cutting depth increases, the lubricating liquid can only be poured on the top of the saw blade when pouring, because the saw blade side wall contacts the raw material, so that the lubricating liquid is difficult to flow to the contact place between the saw blade and the raw material, thus aggravating the wear of the saw blade.

[0004] The above information disclosed in the background section is only used to enhance the understanding of the background of the present disclosure, so it can include information that does not constitute prior art known to those of ordinary skill in the art. SUMMARY

[0005] The purpose of the present application is to design a sawing device that can still apply lubricating liquid to the saw blade between the saw blade and the raw material as the cutting depth of the saw blade increases, thereby reducing the wear of the saw blade and prolonging the service life, to solve the above problems in the art.

[0007] The pressing assembly ensures that the lubricating assembly descends synchronously with the saw blade when sawing the raw material, and applies lubricating liquid to the saw blade and the saw blade side wall.

[0010] Preferably, the thickness of the side of the liquid injection shell close to the stationary part is less than the thickness of the side of the liquid injection shell away from the stationary part.

[0011] Preferably, the lubricating assembly further comprises a guide fin fixed on the outer wall of the liquid injection shell, a guide rod penetrating and slidingly installed in the guide fin, a baffle fixed on the top end of the guide rod, and a first spring sleeved on the guide rod, one end of the first spring being in contact with the bottom surface of the guide fin, the other end of the first spring being in contact with the top surface of the driving part, and the guide rod being lower than the top surface of the driving part fixedly connected.

[0012] Preferably, the stationary part and the driving part are both penetrated by a cutting groove for the descent of the saw blade, the cutting groove and the spray groove are in the same plane, and the outer wall of the liquid injection shell is in contact with the driving part.

[0013] Preferably, the pressing assembly comprises a connecting block fixedly connected with the outer wall of the guide arm, a sliding rod penetrating and slidingly installed in the connecting block, a pressing block fixedly installed on the side of the sliding rod close to the stationary part, a second spring sleeved on the sliding rod, a nut threadedly connected with the end of the sliding rod, and a pressing fin in contact with the bottom of the pressing block, the pressing fin being fixedly connected with the outer wall of the liquid injection shell, and the second spring being located between the pressing block and the connecting block.

[0014] Preferably, the bottom of the pressing block is transversely penetrated by a through groove for the saw blade to pass through, the through groove makes the pressing block form an inverted U shape, and when the pressing block is in contact with the pressing fin, the saw blade does not contact the pressing block in the through groove.

Furthermore, lubricating oil is sprayed from the spray groove onto the side wall where the raw material and the saw blade come into contact. This allows the lubricating oil to be located between the saw teeth and the cutting area of ​​the raw material when the saw teeth are cutting, thus providing lubrication and cooling, and improving the service life of the saw teeth.

[0028] To enable those skilled in the art to better understand the technical solutions in this application, the technical solutions in the embodiments of this application will be clearly and completely described below. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0029] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0030] This invention provides, for example Figures 1-6 The high-performance sawing device for joint raw materials shown includes a worktable 2 as in the prior art. A lifting module 3 that can be raised and lowered is installed on the worktable 2. A saw blade 4 is installed inside the lifting module 3. At the same time, two guide arms 5 are installed on the lifting module 3 to guide the saw blade 4 so that the saw teeth of the saw blade 4 are perpendicular to the worktable 2, that is, perpendicular to the horizontal plane. A clamping module 6 is installed on the worktable 2 to clamp the raw material 1, so as to facilitate the saw blade 4 to saw the raw material 1.

[0031] The clamping module 6 includes an active component 602 fixedly installed on the workbench 2, a connecting rod 603 fixedly installed on one side of the active component 602, a positioning block 604 fixedly installed at the end of the connecting rod 603, a hydraulic cylinder 605 fixedly installed on the side of the positioning block 604 near the active component 602, and an active component 602 fixedly installed at the output end of the hydraulic cylinder 605. A support block is fixedly installed on the opposite side of the active component 602 and the driven component. When the hydraulic cylinder 605 drives the active component 602 to cooperate with the stationary component 601 to clamp the raw material 1, the support block provides support for the raw material 1. At the same time, the active component 602 and the stationary component 601 have cutting grooves 9 for the saw blade 4 to descend. In this way, when the raw material 1 is clamped, there is a certain distance between it and the workbench 2, so that when the saw blade 4 has completely cut the raw material 1, the saw blade 4 is located below the raw material 1 in the cutting groove 9, but does not come into contact with the active component 602 or the stationary component 601.

[0032] Multiple guide rods 707 are fixedly installed on the drive member 602. Guide plates 706 are slidably installed through the guide rods 707. Liquid injection shells 701 are fixedly installed between the guide plates 706. The side wall of the liquid injection shell 701 is in contact with the side wall of the drive member 602. At the same time, baffles 708 are fixedly installed at the top of each guide rod 707. A first spring 709 is sleeved on the outside of the guide rod 707. One end of the first spring 709 is in contact with the bottom surface of the guide plate 706, and the other end is in contact with the drive member 602. The spring will apply an upward elastic force to the guide plate 706, pushing the top surface of the guide plate 706 to contact the bottom surface of the baffle 708. These structures constitute the lubrication assembly 7 for lubricating and cooling the saw blade 4.

[0033] The injection housing 701 has a receiving cavity 702. A transversely penetrating wetting groove 703 is formed at the top of the injection housing 701. The width of the wetting groove 703 is slightly larger than the width of the saw blade 4, ensuring that the saw blade 4 does not contact the injection housing 701 on the inner wall of the wetting groove 703, but there is a certain gap for the lubricant to flow out. At the same time, a spraying groove 704 is formed on the side of the injection housing 701 near the stationary part 601, which communicates with the wetting groove 703. The width of the spraying groove 704 is less than or equal to the width of the cutting groove 9, ensuring that the lubricant sprayed from the spraying groove 704 can pass through the cutting groove 9. A lubricating pipe 705 is fixedly installed on one side of the injection shell 701 on the side wall where the raw material 1 contacts the saw blade 4. Injecting lubricating fluid into the injection pipe 705 fills the receiving cavity 702. Since the bottom and sides of the saw blade 4 occupy a certain volume within the wetting tank 703, and the width of the spray channel 704 is greater than that of the wetting tank 703, most of the liquid will be sprayed through the spray channel 704 onto the area where the raw material 1 contacts the saw blade 4. A portion will also be sprayed through the gap between the saw blade 4 and the wetting tank 703 onto the bottom and side walls of the saw blade 4. The lubricating fluid will also be released from the injection shell 701. 01. The liquid flows out from the side away from the spray channel 704. Therefore, we set the thickness of the side of the injection shell 701 away from the spray channel 704 to be much greater than the side near the stationary part 601. This, combined with the movement of the saw teeth at the bottom of the saw blade 4, creates a gap between the bottom of the saw teeth and the bottom of the immersion tank 703. Because the saw blade 4 moves from the driving part 602 towards the stationary part 601, the air gap between the saw teeth at the bottom of the saw blade 4, which was originally outside the injection shell 701, will flow out from the side of the immersion tank 703 away from the stationary part 601 as it moves into the injection shell 701. The scraping of the lubricant keeps it between the teeth at the bottom of the saw blade 4. At the same time, the gap between the wetting tank 703 and the side wall of the saw blade 4 causes the lubricant to adhere to the side wall of the saw blade 4. Therefore, when the saw blade 4 moves out of the liquid injection shell 701, a thin layer of lubricant oil film is attached to both sides of the saw blade 4. Due to the liquid tension of the lubricant, lubricant droplets will be attached to the space between the teeth at the bottom of the saw blade 4. Therefore, when the saw blade 4 cuts the raw material 1, the lubricant droplets between the teeth at the bottom of the saw blade 4 and the lubricant oil film on both sides of the saw blade 4 will play a role in cooling and lubrication.

[0034] To ensure that the lubrication housing 701 descends synchronously with the saw blade 4 as it cuts the raw material 1, thus guaranteeing lubrication and cooling of the saw blade 4, two connecting blocks 801 are fixedly installed on the guide arm 5 near the lubrication housing 701. A sliding rod 802 is slidably installed through and within each connecting block 801. A pressing block 803 is fixedly installed at one end of each sliding rod 802 near the lubrication housing 701. A through groove 10 is horizontally passed through the bottom of the pressing block 803 for the saw blade 4 to pass through, forming an inverted U-shape. A nut 805 is threaded onto the end of each sliding rod 802. The pressing block 803 and... A second spring 804 is provided between the connecting blocks 801 and sleeved on the slide rod 802. By rotating the nut 805, the position of the slide rod 802 on the connecting block 801 can be adjusted, thereby compressing or releasing the second spring 804. This adjusts the horizontal position of the pressing block 803 at the top of the injection shell 701. To ensure that the pressing block 803 accurately presses the injection shell 701 downward, a pressing plate 806 that cooperates with the pressing block 803 is fixedly installed on the outer wall of the injection shell 701. When the pressing block 803 contacts the pressing plate 806, the saw blade 4 does not contact the pressing block 803 in the groove 10.

[0035] When using this device, first place the workpiece between the stationary part 601 and the driving part 602, extend the output shaft of the hydraulic cylinder 605, and use the driving part 602 to clamp the workpiece in conjunction with the stationary part 601, so that the workpiece is located on the support block. Then, turn the nut 805 to move the pressing block 803 to directly above the pressing plate 806 on the injection shell 701. Then, operate the lifting module 3 to drive the guide arm 5 and the saw blade 4 to descend until the pressing block 803 contacts the pressing plate 806, and the saw blade 4 is inserted into the immersion tank 703. At this time, the saw blade 4 moves at high speed to cut into the injection pipe 705. When lubricant is injected, an oil film will adhere to the side wall of the saw blade 4 inside the injection shell 701, and droplets will appear between the teeth at the bottom of the saw blade 4. The lubricant will be sprayed from the spray groove 704 onto the side wall where the raw material 1 and the saw blade 4 come into contact. As the saw blade 4 begins to cut the raw material 1 and gradually descends, the pressing block 803 will drive the injection shell 701 to descend synchronously through the pressing plate 806, thereby compressing the first spring 709. The droplets between the teeth and the oil film on the side wall of the saw blade 4 play a role in lubrication and cooling during sawing. Together with the lubricant sprayed from the spray groove 704, it plays an auxiliary role in sawing.

[0036] It is important to note that the constructions and arrangements of this application shown in several different exemplary embodiments are merely illustrative. Although only a few embodiments are described in detail in this disclosure, those who consult this disclosure will readily understand that many modifications are possible (e.g., changes in the size, dimensions, structure, shape and proportion of various elements, as well as parameter values ​​(e.g., temperature, pressure, etc.), installation arrangements, use of materials, color, orientation, etc.) without substantially departing from the novel teachings and advantages of the subject matter described in this application.
