Description

Technical Field

[0001] The present invention relates to the technical field of boring equipment, and particularly relates to a boring processing device for stainless steel pipes. Background Art

[0002] Boring is to cut the holes of workpieces through a boring tool to make the holes reach the designed roughness, roundness or finish, etc. Usually, the boring tool is installed on a boring machine through a boring bar, and the boring tool and the workpiece rotate relatively to perform cutting.

[0003] The material of stainless steel workpieces is relatively hard. During the cutting process of the boring tool, a large amount of heat will be generated, and it is necessary to cool the tool in time to improve the service life of the tool. Existing equipment usually directly aims the nozzle of the coolant at the tool and sprays the coolant at a constant flow rate to wash and cool it. However, the heat generated by the tool heating increases with the increase of the cutting speed and the cutting amount, and the constant coolant spray cannot automatically adjust the coolant consumption according to the heat generated during the actual cutting process. The constant flow spray not only causes waste of coolant, but also a large amount of iron filings are mixed in the coolant in the later stage, increasing the workload of coolant filtration and reuse. For this reason, we propose a boring processing device for stainless steel pipes. Summary of the Invention

[0004] The purpose of the present invention is to provide a boring processing device for stainless steel pipes to solve the problems raised in the above background art.

[0005] To achieve the above purpose, the present invention provides the following technical solution: A boring processing device for stainless steel pipes includes a base. At one end of the base, two sliding grooves are symmetrically opened. Two tool holders are slidably connected in the two sliding grooves. The two tool holders are centrosymmetric about the axis of the base. Knife grooves are opened at the ends of the tool holders. Blades are fixed in the knife grooves through bolts. An annular groove is opened at the bottom surface of the knife groove. A rotating shaft fixedly connected to the base is provided between the two sliding grooves. The axis of the rotating shaft coincides with the axis of the base. An adjusting disk is rotatably connected to the rotating shaft. The adjusting disk is detachably fixed to the base through bolts. Two centrosymmetric arc-shaped grooves are provided on the adjusting disk. The connecting line of the centers of the two arc-shaped grooves intersects with the axis of the rotating shaft. A sliding rod is slidably connected in each arc-shaped groove. The end of the sliding rod away from the adjusting disk is fixedly connected to the corresponding tool holder. A cooling device is provided between the base and each tool holder. The cooling device includes a mounting block fixedly connected to the base and a support plate fixedly connected to the tool holder. A liquid supply pipe penetrates through the mounting block. A universal hose penetrates through the support plate. A nozzle is fixed at the end of the universal hose. A flow splitting assembly is provided between the universal hose and the liquid supply pipe. An adjusting assembly for dynamically adjusting the flow splitting assembly is provided in the tool holder.

[0006] Preferably, the flow splitting assembly includes a movable frame communicated with the liquid supply pipe. A flow splitting sleeve is fixed inside the movable frame. The flow splitting sleeve is made of high-elastic silica gel. An upper flow splitting channel and a lower flow splitting channel are provided on the flow splitting sleeve. A push plate is fixed in the middle of the flow splitting sleeve. One end of the push plate away from the flow splitting sleeve is fixedly connected to the support plate. The lower flow splitting channel is communicated with the universal hose. The upper flow splitting channel is communicated with a return pipe. One end of the return pipe away from the flow splitting sleeve penetrates through the mounting block and is communicated with a liquid storage tank filled with coolant.

[0007] Preferably, the adjusting assembly includes a heat conducting ring attached to the lower surface of the blade. The heat conducting ring is arranged in the annular groove. An annular liquid bag is arranged below the heat conducting ring. A plurality of heat conducting rods are fixed on the heat conducting ring. One end of the heat conducting rod away from the heat conducting ring penetrates into the annular liquid bag. A transmission component is arranged between the annular liquid bag and the movable frame.

[0008] Preferably, the transmission component includes a support ring arranged at the bottom of the annular liquid bag. A spring sleeved in the annular groove is arranged below the support ring. A transmission plate is fixed on the side surface of the support ring. The transmission plate is slidably connected with the tool holder. A column is fixed on the transmission plate. One end of the column slidably penetrating through the tool holder is fixedly connected to the movable frame.

[0009] Preferably, the tool holder is provided with a ventilation hole communicated with the annular groove.

[0010] Preferably, the axis of the upper flow splitting channel, the axis of the lower flow splitting channel and the push plate are parallel.

[0011] Preferably, receiving grooves are symmetrically formed on both sides of the flow splitting sleeve. The receiving grooves surround the upper flow splitting channel and the lower flow splitting channel.

[0012] Preferably, a partition plate is fixed above one end of the transmission plate close to the support ring.

[0013] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0014] 1. The present invention uses the flow splitting assembly to correspondingly adjust the liquid flow rate conveyed from the liquid supply pipe to the nozzle according to the magnitude of the heat generated during the cutting of the blade. An adjusting assembly for dynamically adjusting the flow splitting assembly is arranged in the tool holder. When the heat generated during the cutting of the blade is large, the adjusting assembly controls the flow splitting assembly to split the coolant in the liquid supply pipe, increasing the coolant output at the nozzle for better cooling. When the heat generated during the cutting is small, the coolant output at the nozzle is reduced, saving the coolant output. At the same time, the split coolant flows into the liquid storage tank, reducing the waste of coolant and reducing the workload of subsequent coolant filtration and reuse.

[0015] 2. The present invention drives the movable frame to move up and down through the adjustment component, and then drives the push plate to stretch and squeeze the upper shunt channel and the lower shunt channel. When the generated heat is large, the movable frame moves down a large distance, so the opening of the lower shunt channel increases, and more coolant flows through. More coolant is sprayed onto the blade through the universal hose and the nozzle for cooling. The opening of the upper shunt channel decreases, the flowing coolant reduces, and it flows back to the liquid storage tank.

[0016] 3. The present invention transfers heat to the volatile liquid in the annular liquid sac through the heat conduction ring and the heat conduction rod. The liquid volatilizes when heated, the annular liquid sac expands, drives the support ring to move down, and then drives the transmission plate and the column to move down, and further drives the movable frame to move down. It can better adapt to different moving distances according to different calorific values, and then control the outflow of different flow rates of coolant, saving coolant.

[0025] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0026] Please refer to Figures 1-6 , the present invention provides a technical solution: a boring processing device for stainless steel pipes, including a base 1, the base 1 is installed on a boring machine through a boring bar, two chutes are symmetrically opened at one end of the base 1, and two tool holders 2 are slidably connected in the two chutes. The two tool holders 2 are centrosymmetric about the axis of the base 1. Knife grooves 3 are opened at the ends of the tool holders 2, and cutting blades 4 are fixed in the knife grooves 3 through bolts. Annular grooves 5 are opened at the bottoms of the knife grooves 3. A rotating shaft 6 fixedly connected to the base 1 is provided between the two chutes. The axis of the rotating shaft 6 coincides with the axis of the base 1. An adjusting disk 7 is rotatably connected to the rotating shaft 6. The adjusting disk 7 is provided with scales. The adjusting disk 7 is detachably fixed to the base 1 through bolts. The adjusting disk 7 is provided with two centrosymmetric arc-shaped grooves 8. The connecting line of the centers of the two arc-shaped grooves 8 intersects the axis of the rotating shaft 6. A sliding rod 9 is slidably connected in each arc-shaped groove 8. The end of the sliding rod 9 away from the adjusting disk 7 is fixedly connected to the corresponding tool holder 2. A cooling device is provided between the base 1 and each tool holder 2. The cooling device includes a mounting block 10 fixedly connected to the base 1 and a support plate 11 fixedly connected to the tool holder 2. A liquid supply pipe 12 is penetrated through the mounting block 10. The liquid supply pipe 12 is used for transporting coolant and is connected to an existing infusion pump (not shown in the figure). A universal hose 13 is penetrated through the support plate 11. A spray head 14 is fixed at the end of the universal hose 13. When selecting cutting blades 4 of different sizes, the angle of the spray head 14 is adjusted through the universal hose 13 to align with the edge of the cutting edge to cool the cutting blade 4. A flow splitting component is provided between the universal hose 13 and the liquid supply pipe 12. The flow splitting component is used to correspondingly adjust the liquid flow rate transported from the liquid supply pipe 12 to the spray head 14 according to the magnitude of the heat generated during the cutting of the cutting blade 4. An adjusting component for dynamically adjusting the flow splitting component is provided in the tool holder 2. When the heat generated by the cutting of the cutting blade 4 is relatively large, the adjusting component controls the flow splitting component to split the coolant in the liquid supply pipe 12 to increase the coolant output at the spray head 14 for better cooling. When the heat generated by the cutting is small, the coolant output at the spray head 14 is reduced to save the coolant output. At the same time, the split coolant is circulated to a liquid storage tank to reduce the waste of coolant and reduce the workload of subsequent coolant filtration and reuse.

[0027] Specifically, please refer to Figure 3 , Figure 4 and Figure 6, The flow splitting component includes a movable frame 15 communicated with the liquid supply pipe 12. A flow splitting sleeve 16 is fixed inside the movable frame 15. The outer wall of the flow splitting sleeve 16 is closely attached to the inner wall of the movable frame 15. The flow splitting sleeve 16 is made of high-elastic silicone rubber and has certain elasticity and ductility. An upper flow splitting channel 17 and a lower flow splitting channel 18 are provided on the flow splitting sleeve 16. A push plate 19 is fixed in the middle of the flow splitting sleeve 16. The push plate 19 is located between the upper flow splitting channel 17 and the lower flow splitting channel 18. One end of the push plate 19 away from the flow splitting sleeve 16 is fixedly connected to the support plate 11. The lower flow splitting channel 18 is communicated with the universal hose 13. The upper flow splitting channel 17 is communicated with a return pipe 20. One end of the return pipe 20 away from the flow splitting sleeve 16 penetrates through the mounting block 10 and is communicated with a liquid storage tank filled with coolant. By driving the movable frame 15 to move up and down through the adjusting component, the push plate 19 is driven to stretch and squeeze the upper flow splitting channel 17 and the lower flow splitting channel 18. When the generated heat is large, the movable frame 15 moves down a large distance, and then the opening of the lower flow splitting channel 18 increases, and more coolant flows through. More coolant is sprayed onto the blade 4 through the universal hose 13 and the nozzle 14 for cooling. The opening of the upper flow splitting channel 17 decreases, and less coolant flows through and flows back into the liquid storage tank.

[0028] In addition, it should be noted that the heat generated by the blade 4 is not only related to the material being cut, but also related to the feed per cut and the rotational speed of the boring tool. The larger the single feed amount and the rotational speed, the more heat is generated. The smaller the feed amount and the rotational speed, the less heat is generated.

[0029] Specifically, please refer to Figure 3 、 Figure 4 and Figure 5 , The adjusting component includes a heat conducting ring 21 attached to the lower surface of the blade 4. The heat conducting ring 21 is arranged in the annular groove 5. An annular liquid sac 22 is arranged below the heat conducting ring 21. The annular liquid sac 22 has certain elasticity and can expand and contract. The annular liquid sac 22 is filled with a volatile liquid. A plurality of heat conducting rods 23 are fixed on the heat conducting ring 21. One end of the heat conducting rod 23 away from the heat conducting ring 21 penetrates into the interior of the liquid sac. A transmission component is arranged between the liquid sac and the movable frame 15.

[0030] Specifically, please refer to Figure 4 and Figure 5 , The transmission component includes a support ring 24 arranged at the bottom of the liquid sac. A spring 25 sleeved in the annular groove 5 is arranged below the support ring 24. A transmission plate 26 is fixed on the side of the support ring 24. The transmission plate 26 is slidably connected to the tool holder 2. A column 27 is fixed on the transmission plate 26. One end of the column 27 slidably penetrating through the tool holder 2 is fixedly connected to the movable frame 15.

[0031] In this solution, during the working process of the adjusting component, when the blade 4 cuts the workpiece, the blade 4 generates heat. Through the heat-conducting ring 21 and the heat-conducting rod 23, the heat is transferred to the volatile liquid in the annular liquid sac 22. The liquid volatilizes when heated, and the annular liquid sac 22 expands, driving the support ring 24 to move downward, and then driving the transmission plate 26 and the column 27 to move downward, and further driving the movable frame 15 to move downward.

[0032] Specifically, please refer to Figure 5 and Figure 6 There is a vent hole 28 on the tool holder 2 that communicates with the annular groove 5, which is used to discharge the gas in the tool holder 2 when the volume of the annular liquid sac 22 increases.

[0033] Specifically, please refer to Figure 3 and Figure 6 The axes of the upper shunt channel 17 and the lower shunt channel 18 are parallel to the push plate 19, which can reduce the impact of the coolant flow on the shunt sleeve 16.

[0034] Specifically, please refer to Figure 4 and Figure 6 On both sides of the shunt sleeve 16, accommodation grooves are symmetrically arranged. The accommodation grooves surround the upper shunt channel 17 and the lower shunt channel 18, and the accommodation grooves provide space for the deformation of the shunt grooves.

[0035] Specifically, please refer to Figure 4 and Figure 5 Above one end of the transmission plate 26 close to the support ring 24, a partition plate 29 is fixed to prevent the expanded annular liquid sac 22 from squeezing into the space where the transmission plate 26 is placed, ensuring the stable expansion and contraction of the annular liquid sac 22.
