Description

Technical Field

[0001] The present invention relates to the technical field of intelligent manufacturing equipment industry, and particularly relates to a sawing machine feed assisting mechanism. Background Art

[0002] Sawing machines are mainly used for cutting various metal materials, including round materials, square materials, pipe materials, profiles, etc. They are usually used in the stock preparation workshop to cut various bar materials, pipe materials and other profiles. The processing accuracy of sawing machines is generally not high, but their main function is to saw off materials through tools such as circular saw blades, saw bands or saw strips.

[0003] To solve the problems in the prior art that the positioning of the sawing machine for plates is not accurate enough, plates of different sizes cannot be calibrated and positioned before sawing, and it is easy to generate shaking during sawing, resulting in low sawing accuracy, Chinese Patent Publication No. "CN107855595B" proposes a fully automatic multi-position high-speed sawing machine for plates. It mainly performs three-dimensional positioning of the plate in the front, back, left, right, up and down directions, so that the positioning of the whole plate during sawing is more accurate. Plates of different sizes can be calibrated and positioned before sawing, and it is not easy to generate shaking during sawing, and the sawing accuracy is relatively high. The structure is simple and reasonable. However, in this solution, no improvement is made to the saw disk itself. Therefore, there is a certain instability when the saw disk performs the feeding work, the saw blade may shift, and the accuracy of the sawing machine feeding work cannot be guaranteed; and no special saw blade cooling structure is provided. When the sawing machine feeds, the temperature of the saw blade is extremely high. Under long-term work, the service life of the saw blade is relatively low and it is easy to deform, which will also affect the sawing machine feeding accuracy. Summary of the Invention

[0004] The purpose of the present invention is to solve the disadvantages existing in the prior art, and to propose a sawing machine feed assisting mechanism, which can accurately position the saw disk, assist in improving the stability of the sawing machine feeding work, keep the saw blade from shifting, and improve the accuracy, efficiency and quality of the sawing machine feeding work.

[0005] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0006] A sawing machine feed assisting mechanism includes a bottom plate, an auxiliary positioning assembly, an auxiliary liquid cooling assembly and a coolant circulation assembly.

[0007] The auxiliary positioning assembly is composed of a connecting positioning plate, an outer side plate and an inner side plate, and is used to assist in accurately positioning the saw disk during the sawing machine feeding, and change the chip removal direction. The connecting positioning plate is fixedly connected to the bottom plate. The outer side plate and the inner side plate are respectively arranged on both sides of the connecting positioning plate, and a chip removal hole with a downward opening and a trapezoidal cross-section is jointly formed at their ends. The auxiliary positioning assembly is driven to work by a hydraulic structure.

[0008] The auxiliary liquid cooling component is composed of a device seat, a first pump, liquid cooling pipes, and multiple liquid spray nozzles, and is used to spray coolant onto the saw blade to assist in cooling the saw blade. A liquid storage cavity is formed in the device seat, and a serpentine cooling pipe extending outside the device seat is arranged in the liquid storage cavity. The first pump is fixed on the side wall of the device seat, its liquid inlet is communicated with the liquid storage cavity through a liquid inlet pipe, and its liquid outlet is communicated with the liquid cooling pipes through a liquid outlet pipe. The multiple liquid spray nozzles are evenly distributed on the side of the liquid cooling pipes and all face the direction of the saw disc;

[0009] The coolant circulation component is composed of a liquid collecting tank and a second pump, and is used to collect the coolant spilled after spraying. The liquid collecting tank is arranged at the upper end of the device seat, and the second pump is fixed on the side wall of the device seat. Its liquid inlet is communicated with the liquid collecting tank through a circulation pipe, and its liquid outlet is communicated with the liquid storage cavity through a return pipe.

[0010] Preferably, guide rail sliders and drag chain brackets are respectively and fixedly installed on both sides of the bottom plate for movable connection with the sawing machine body. First wear-resistant tungsten carbide sheets and second wear-resistant tungsten carbide sheets are respectively and fixedly arranged on the upper sides of the ends of the outer side plate and the inner side plate.

[0011] Preferably, the hydraulic structure includes a first hydraulic cylinder, a second hydraulic cylinder, a positioning sliding shaft, and an oil inlet pipe. The first hydraulic cylinder and the second hydraulic cylinder are fixedly integrated in parallel and communicated with the oil inlet pipe, and a synchronous valve is arranged on the upper part of the cylinder body. The first hydraulic cylinder and the second hydraulic cylinder are synchronously movably connected with the inner side plate, and a tension spring is arranged inside. The positioning sliding shaft is arranged between the outer side plate and the inner side plate for keeping the displacement directions of the outer side plate and the inner side plate.

[0012] Preferably, a filter plate is fixedly installed at the upper end of the liquid collecting tank. The filter plate is linearly provided with seepage holes for separating the coolant and workpiece debris falling into the liquid collecting tank.

[0013] Preferably, an inflatable enclosure is arranged around the upper end of the device seat at the notch of the liquid collecting tank. The inflatable enclosure expands longitudinally and rises in height when inflated, and contracts longitudinally and decreases in height when exhausting. A pair of sliding plates are symmetrically and slidably connected to the device seat. The pair of sliding plates are respectively fixedly connected to the outer side plate and the inner side plate through connecting rods, and a control structure for controlling the lifting of the inflatable enclosure is installed between the pair of sliding plates.

[0014] Preferably, the control structure includes a telescopic airbag. The two ends of the telescopic airbag are respectively fixedly connected to the inner sides of the pair of sliding plates, and the two ends of the telescopic airbag are respectively communicated with the two ends of the inflatable enclosure through air guide pipes.

[0015] Preferably, a pushing structure for extending the serpentine cooling pipe during operation is installed at the upper end of the device base. The pushing structure includes gears, a first rack, and a second rack. A pair of the gears are symmetrically and rotatably connected to the upper end of the device base. The first rack and the second rack are both slidably connected to the upper end of the device base. The first rack and the second rack are arranged on both sides of the gears and are both engaged with the gears. The first rack is fixedly connected to the sliding plate, and the second rack is fixedly connected to the serpentine cooling pipe through a bent rod.

[0016] Preferably, after the first hydraulic cylinder and the second hydraulic cylinder reach the set pressure, there are corresponding gaps between the first wear-resistant tungsten carbide sheet and the second wear-resistant tungsten carbide sheet and both sides of the saw blade, and the saw blade and the workpiece are kept at a certain angle during work.

[0017] The present invention has the following beneficial effects:

[0018] 1. By setting the auxiliary positioning component and the hydraulic structure, when the sawing machine feeds, the pressures of the first and second hydraulic cylinders are greater than the spring tension to form a pressing force. When the first and second hydraulic cylinders reach the sensor pressure, they automatically stop. During work, the set pressure is always maintained. If the pressure is insufficient, the hydraulic system starts to automatically supplement the pressure. After the hydraulic cylinders reach the set pressure, there are corresponding gaps between the first and second wear-resistant tungsten carbide sheets at the front and both sides of the saw blade, and the saw blade and the workpiece are kept at 90 degrees during work. The feeding auxiliary mechanism always moves forward synchronously with the saw blade during work. When the work process is completed, a signal is given to the hydraulic system to make the first and second hydraulic cylinders retract and the first and second wear-resistant tungsten carbide sheets open, completing an entire work process, thereby assisting in improving the stability of the sawing machine feeding work, keeping the saw blade from shifting, and enhancing the accuracy, efficiency, and quality of the sawing machine feeding work;

[0019] 2. By setting the auxiliary liquid cooling component, when the sawing machine is working, the first pump pumps the coolant in the liquid storage cavity into the cooling channel, and then it sprays out from each liquid spray nozzle on the side wall of the cooling channel onto the surface of the saw blade, which can effectively assist in cooling the saw blade during work, thereby avoiding long-term high-temperature operation, extending the service life of the saw blade, preventing the saw blade from deforming, and further ensuring the feeding accuracy of the sawing machine;

[0020] 3. By setting the coolant circulation component, first, the debris generated during the sawing machine feeding and the coolant sprayed and falling during cooling can be collected. The coolant and the debris are screened and separated by the filter plate, and the second pump pumps the coolant in the liquid collection tank back into the liquid storage cavity, thereby forming a recycling of the coolant. The serpentine cooling pipe arranged in the liquid storage cavity can keep the coolant in heat exchange with the air, thereby ensuring that the coolant is always in a low-temperature state;

[0021] 4. By setting up an inflatable enclosure, a control structure, and a pushing structure, when the sawing machine feeds, the telescopic airbag can be compressed, thereby inflating the inflatable enclosure to make it rise, ensuring that it can catch debris and coolant more precisely and preventing the coolant and debris from splashing. Moreover, when the sliding plate slides along with the outer plate and the inner plate, the first rack will slide synchronously. Through the meshing action of the gear, the first rack indirectly drives the second rack to slide and open to both sides. When the second rack slides, it drives the serpentine cooling pipe to extend outward from the device seat, thereby increasing the contact area between the serpentine cooling pipe and the external air. When circulating the coolant, it has a better heat dissipation effect, which can better ensure that the coolant in the liquid storage cavity always remains at a low temperature.

Embodiment 1

[0031] Referring to Figure 1 , a sawing machine feeding auxiliary mechanism includes a bottom plate 1 and an auxiliary positioning assembly. The auxiliary positioning assembly is composed of a connecting positioning plate 2, an outer side plate 3, and an inner side plate 4, and is used to assist in accurately positioning the saw blade during the feeding of the sawing machine and change the chip removal direction. The connecting positioning plate 2 is fixedly connected to the bottom plate 1. The outer side plate 3 and the inner side plate 4 are respectively arranged on both sides of the connecting positioning plate 2, and the ends of the two together form a chip removal hole 13 with a downward opening and a trapezoidal cross-section. The auxiliary positioning assembly is driven by a hydraulic structure.

[0032] Guide rail sliders 10 and drag chain brackets 11 are respectively fixedly installed on both sides of the bottom plate 1 for movably connecting with the sawing machine body. First wear-resistant tungsten carbide sheets 8 and second wear-resistant tungsten carbide sheets 9 are respectively fixedly arranged on the upper sides of the ends of the outer side plate 3 and the inner side plate 4.

[0033] The hydraulic structure includes a first hydraulic cylinder 5, a second hydraulic cylinder 6, a positioning sliding shaft 7, and an oil inlet pipe 12. The first hydraulic cylinder 5 and the second hydraulic cylinder 6 are fixedly integrated in parallel and communicated with the oil inlet pipe 12, and a synchronous valve is provided on the upper part of the cylinder body. The first hydraulic cylinder 5 and the second hydraulic cylinder 6 are synchronously movably connected to the inner side plate 4, and a tension spring is arranged inside. The positioning sliding shaft 7 is arranged between the outer side plate 3 and the inner side plate 4 for maintaining the displacement direction of the outer side plate 3 and the inner side plate 4.

[0034] After the first hydraulic cylinder 5 and the second hydraulic cylinder 6 reach the set pressure, corresponding gaps are left between the first wear-resistant tungsten carbide sheet 8 and the second wear-resistant tungsten carbide sheet 9 and both sides of the saw blade, and the saw blade is kept at 90 degrees with the workpiece during working.

[0035] In this embodiment, the feeding auxiliary mechanism can assist in maintaining the precise positioning of the saw blade, change the chip removal direction, work synchronously with the main saw blade during operation. When the system gives a completion signal after the operation is completed, the power unit of the hydraulic system automatically supplies oil to the first hydraulic cylinder 5 and the second hydraulic cylinder 6, and the outer plates 3 and the inner plates 4 open synchronously to complete one operation. The power part is fixedly integrated with the first hydraulic cylinder 5 and the second hydraulic cylinder 6. A synchronous valve is provided at the upper part of the cylinder body. The first hydraulic cylinder 5 and the second hydraulic cylinder 6 work synchronously. A tension spring is provided inside. When not working, the spring opens. When working, the pressure of the hydraulic cylinder is greater than the spring tension to form a pressing force. A connecting positioning plate 2 is provided in the middle. When the two hydraulic cylinders reach the sensor pressure, they automatically stop and always maintain the set pressure during operation. If the pressure is insufficient, the hydraulic system starts automatic pressure compensation. The front part is provided with a first wear-resistant tungsten carbide sheet 8 and a second wear-resistant tungsten carbide sheet 9. After the two hydraulic cylinders reach the set pressure, there are corresponding gaps between the two front wear-resistant tungsten carbide sheets and the two sides of the saw blade. During operation, the saw blade is kept at 90 degrees with the workpiece. The feeding auxiliary mechanism always moves forward synchronously with the saw blade during operation. When the operation program is completed, a signal is sent to the hydraulic system to make the two hydraulic cylinders retract and the two wear-resistant tungsten carbide sheets open, completing an entire operation, thereby assisting in improving the stability of the sawing machine feeding operation, keeping the saw blade from shifting, and enhancing the accuracy, efficiency, and quality of the sawing machine feeding work. Embodiment 2

[0036] Different from Embodiment 1, referring to Figures 2-3 , this embodiment further has the following content:

[0037] It further includes an auxiliary liquid cooling component and a coolant circulation component. The auxiliary liquid cooling component is composed of a device seat 14, a first pump 17, a liquid cooling pipe 21, and a plurality of spray nozzles 25, and is used to spray coolant on the saw blade to assist in cooling the saw blade. A liquid storage cavity is opened in the device seat 14, and a serpentine cooling pipe 20 extending outside the device seat 14 is provided in the liquid storage cavity. The first pump 17 is fixed on the side wall of the device seat 14. Its liquid inlet is communicated with the liquid storage cavity through a liquid inlet pipe 18, and its liquid outlet is communicated with the liquid cooling pipe 21 through a liquid outlet pipe 19. The plurality of spray nozzles 25 are evenly distributed on the side of the liquid cooling pipe 21 and all face the direction of the saw disc;

[0038] The coolant circulation component is composed of a liquid collecting tank 15 and a second pump 22, and is used to collect the coolant spilled after spraying. The liquid collecting tank 15 is opened at the upper end of the device seat 14. The second pump 22 is fixed on the side wall of the device seat 14. Its liquid inlet is communicated with the liquid collecting tank 15 through a circulation pipe 23, and its liquid outlet is communicated with the liquid storage cavity through a return pipe 24.

[0039] A filter plate 16 is fixedly installed at the upper end of the liquid collecting tank 15. The filter plate 16 is linearly provided with seepage holes for separating the coolant and workpiece debris falling into the liquid collecting tank 15.

[0040] In this embodiment, when the sawing machine is working, the first pump 17 pumps the coolant in the liquid storage cavity into the cooling channel 21, and then sprays it onto the surface of the saw blade from each liquid spraying nozzle 25 on the side wall of the cooling channel 21, which can effectively assist in cooling the saw blade during work, thus avoiding long-term high-temperature operation, prolonging the service life of the saw blade, preventing the deformation of the saw blade, and further ensuring the feeding accuracy of the sawing machine;

[0041] And the liquid collecting tank 15 collects the debris generated during the feeding of the sawing machine and the coolant sprayed and dropped during cooling. The coolant and debris are screened and separated by the filter plate 16. At the same time, the second pump 22 works to pump the coolant in the liquid collecting tank 15 back into the liquid storage cavity, and then is pumped into the cooling channel 21 by the first pump 17, so as to form a recycling of the coolant. The serpentine cooling pipe 20 arranged in the liquid storage cavity can maintain the heat exchange between the coolant and the air, so as to ensure that the coolant is always in a low-temperature state. Embodiment Three

[0042] Refer to Figure 4 , compared with Embodiment One and Embodiment Two, in this embodiment, an inflatable enclosure 26 is surrounded at the upper end of the device seat 14 at the notch of the liquid collecting tank 15. The inflatable enclosure 26 inflates and the height rises longitudinally, and deflates and the height decreases longitudinally. A pair of sliding plates 27 are symmetrically and slidably connected to the device seat 14. The pair of sliding plates 27 are respectively fixedly connected to the outer plate 3 and the inner plate 4 through connecting rods 29, and a control structure for controlling the lifting of the inflatable enclosure 26 is installed between the pair of sliding plates 27.

[0043] The control structure includes a telescopic airbag 28. The two ends of the telescopic airbag 28 are respectively fixedly connected to the inner sides of the pair of sliding plates 27, and the two ends of the telescopic airbag 28 are respectively communicated with the two ends of the inflatable enclosure 26 through air ducts 30.

[0044] In this embodiment, when the sawing machine feeds, the first hydraulic cylinder 5 and the second hydraulic cylinder 6 drive the outer plate 3 and the inner plate 4 to squeeze inward, so as to drive the sliding plates to slide inward through a pair of connecting rods 29. At this time, the pair of sliding plates 29 will squeeze the telescopic airbag 28, so that the air in the telescopic airbag 28 flows into the inflatable enclosure 26 through the air duct 30. After the inflatable enclosure 26 is inflated, it will expand longitudinally, so as to rise, and the opening is close to the chip discharge hole 13, ensuring that it can more accurately catch the debris and coolant and transfer them into the liquid collecting tank 15, avoiding the splashing of the coolant and debris and hurting people, and at the same time being more conducive to the recycling of the debris and coolant. Embodiment Four

[0045] Refer to Figures 5-6, compared with the first to third embodiments, a pushing structure for extending the serpentine cooling pipe 20 during operation is installed at the upper end of the device base 14 in this embodiment. The pushing structure includes a gear 32, a first rack 31, and a second rack 33. A pair of gears 32 are symmetrically rotatably connected to the upper end of the device base 14. The first rack 31 and the second rack 33 are both slidably connected to the upper end of the device base 14. The first rack 31 and the second rack 33 are arranged on both sides of the gear 32 and are both engaged with the gear 32. The first rack 31 is fixedly connected to the sliding plate 27, and the second rack 33 is fixedly connected to the serpentine cooling pipe 20 through a bent rod 34.

[0046] In this embodiment, when the sawing machine feeds and works, when the sliding plate 27 slides along with the outer plate 3 and the inner plate 4, the first rack 31 will slide synchronously. The first rack 31 indirectly drives the second rack 33 to slide and open to both sides through the meshing action of the gear 32. When the second rack 33 slides, it drives the serpentine cooling pipe 20 to extend out of the device base 14 through the bent rod 34, thereby increasing the contact area between the serpentine cooling pipe 20 and the external air. When circulating the coolant, it has a better heat dissipation effect and can better ensure that the coolant in the liquid storage cavity is always in a low temperature state.

[0047] When the sawing machine finishes working, the hydraulic pressure of the first hydraulic cylinder 5 and the second hydraulic cylinder 6 decreases, and the outer plate 3 and the inner plate 4 are pulled apart by the springs. At this time, the sliding plate 27 slides to both sides along with the outer plate 3 and the inner plate 4, and the first rack 31 slides to both sides synchronously. The first rack 31 indirectly drives the second rack 33 to slide and approach inward through the meshing action of the gear 32. When the second rack 33 slides, it drives the serpentine cooling pipe 20 to contract towards the inside of the liquid storage cavity through the bent rod 34. At this time, the occupied area of the serpentine cooling pipe 20 can be reduced, and at the same time, it also forms a certain protection for the serpentine cooling pipe 20, avoiding the problem that it is easily damaged due to long-term exposure.

[0048] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, makes equivalent replacements or changes, and should be covered by the protection scope of the present invention.
