Description

Technical Field

[0001] The invention belongs to the field of horizontal roller processing equipment, and more specifically, relates to a high-efficiency processing device for the horizontal roller of a universal rolling mill. Background Art

[0002] With the development of industry, the production capacity demand of heavy equipment processing enterprises has increased, and the consumption of various accessories has increased. For H-beam universal rolling mills, there are a large number of horizontal rollers and the annual consumption is large. In order to ensure that the horizontal rollers can be replaced and supplied in time, it is necessary to increase the manufacturing speed of the horizontal rollers and shorten their delivery period.

[0003] Hole processing is one of the steps in manufacturing horizontal rollers. Due to the slenderness of the roller body, it is inevitable to process long holes. Due to the limitations of hole diameter and hole depth, the existing processing equipment cannot quickly and continuously process the holes of horizontal rollers. On the one hand, rapid processing can easily lead to overheating or vibration damage of the processing equipment. On the other hand, there is the problem of timely discharge of processing waste. Both of them affect the processing efficiency of horizontal rollers, making it difficult for the existing manufacturing speed to meet the delivery deadline requirements, and the manufacturing quality cannot be guaranteed.

[0004] After searching, the Chinese patent publication number is CN201249298Y; the publication date is June 3, 2009; a device for processing the inner hole surface of a slender pipe is disclosed, including a dumpling cutter head and a knife rod for fixing the dumpling cutter head, the dumpling cutter head and the knife rod are movably connected together by a connecting rod, the dumpling cutter head is a floating cutter head made of carbide that can be freely rotated 360° and adjusted radially left and right, the dumpling cutter head is a tooth-thinning cutter head after removing one tooth from the tip of the standard knife head, and the length of the tooth-thinning section is 1 / 2 to 4 / 5 of the total length of the dumpling cutter head; the knife rod is a rod with freely adjustable length. Although the device of this application can solve the problem of the roughness of the hole wall surface during horizontal roller processing, it still cannot adapt to faster processing speeds, otherwise it is easy to cause the knife rod to vibrate and cause damage to the knife rod and tool of the processing device. Summary of the invention

[0005] 1. Problems to be solved

[0006] In view of the problems in the prior art of low manufacturing efficiency and inability to guarantee delivery time of horizontal rollers of universal rolling mills, the present invention provides a high-efficiency processing device for horizontal rollers of universal rolling mills. The waste chips generated during processing are promptly flushed away by a cooling chip removal system to prevent excessive accumulation of waste chips in the holes, thereby saving time for special blowing and chip removal, and eliminating the need to deliberately control the processing speed to prevent overheating, thereby greatly improving the processing efficiency, thereby effectively shortening the manufacturing time of the horizontal rollers, and achieving the purpose of efficiently manufacturing the horizontal rollers.

[0007] 2. Technical solution

[0008] To solve the above problems, the present invention adopts the following technical solutions.

[0009] A high-efficiency processing device for horizontal rolls of a universal rolling mill, comprising:

[0010] Tool bar;

[0011] A cutter head connected to one end of the cutter rod;

[0012] Also included is a cooling and chip removal system, which includes:

[0013] A channel is provided on the cutter bar and the cutter head along the length direction of the cutter bar;

[0014] A cutter head flow channel opening is provided on the cutter head surface toward the inside, and is connected with the channel at one end of the cutter head;

[0015] A knife bar flow channel opening is provided on the surface of the knife bar toward the inside, and is connected with the channel at one end of the knife bar;

[0016] The number of the channels is multiple.

[0017] The cooling and chip removal system consists of multiple channels opened in the tool rod and the cutter head along the length of the tool rod, and the two ends of the channels are connected to the cutter head flow channel opening and the tool rod flow channel opening respectively. During the processing, since the tool rod is stationary, cooling liquid or compressed gas and other cooling media can be poured into the channel through the tool rod flow channel opening, and the poured cooling medium flows out from the tool head flow channel opening located at the tool head through the channel, firstly effectively cooling the tool head to prevent it from overheating and damage. At the same time, the flowing coolant will also promptly wash away the waste chips generated by the processing to prevent excessive accumulation of waste chips in the hole, thereby saving the time for special blowing and chip removal, and there is no need to deliberately control the processing speed to prevent overheating, which greatly improves the processing efficiency, thereby effectively shortening the manufacturing time of the horizontal roller, and achieving the purpose of efficiently manufacturing the horizontal roller. At the same time, the timely removal of waste chips can also effectively avoid the vibration of the tool head and tool rod during the processing, and improve the surface processing quality of the hole wall.

[0018] Furthermore, there are three channels, including:

[0019] A chip removal channel is provided in the middle of the tool bar and the cutter head along the length direction of the tool bar;

[0020] An inlet flow channel is provided beside the chip removal flow channel along the length direction of the tool bar, and compressed gas flows through the inlet flow channel;

[0021] The liquid inlet channel is opened beside the chip removal channel along the length direction of the tool rod, and the cooling liquid flows through the liquid inlet channel.

[0022] This scheme sets up three channels, among which the chip removal channel is set in the middle position, and the inlet channel and the liquid inlet channel are located next to the chip removal channel. The inlet channel is used to pass compressed gas, and the liquid inlet channel is used to pass coolant. During the processing, the coolant flows through the liquid inlet channel and flows out from the cutter head. While cooling the cutter head, the coolant will gradually fill the gap between the cutter head and the hole wall and contact and mix with the retained waste chips. The compressed gas flows through the inlet channel and flows out from the cutter head, which can also cool the cutter head and fully stir the coolant in the hole. Cooling liquid is passed through the hole so that the waste chips deposited in the hole can be fully mixed with the coolant, and the chip removal channel does not discharge the medium into the hole. As the channel closest to the mixed liquid at the tool head and with the lowest pressure, the coolant overflowing from the liquid inlet channel, the gas overflowing from the inlet channel, and the waste chips fully mixed into the coolant will flow into the chip removal channel. Under the condition of continuously pressurizing and replenishing the medium in the liquid inlet channel and the inlet channel, the mixture and liquid flowing into the chip removal channel will be discharged along the tool rod channel opening connected to the chip removal channel, thereby completing the timely, rapid and thorough discharge of the waste chips.

[0023] Furthermore, the air inlet channel and the liquid inlet channel are arranged symmetrically.

[0024] The air inlet channel and the liquid inlet channel are symmetrically arranged on both sides of the chip removal channel to ensure the uniformity of the mass distribution of the device in terms of geometric shape. During rapid hole processing, vibration will not be generated due to uneven mass distribution of the tool rod or tool head, causing damage to the device and affecting the smooth progress of the processing, thereby ensuring the efficient processing of the horizontal roller.

[0025] Furthermore, a cutter head flow channel opening connected to the chip removal flow channel is provided on the end surface of the cutter head away from the cutter rod;

[0026] The cutter head flow channel openings communicating with the inlet flow channel and the liquid inlet flow channel are both arranged on the side wall of the cutter head.

[0027] The cutter head flow channel opening connected to the chip removal channel is set on the end face of the cutter head away from the tool rod. The purpose is to find the place in front of the end face of the cutter head away from the tool rod that is most likely to accommodate waste chips. It is also the place where waste chips are difficult to be removed by ordinary flushing. The cutter head flow channel opening of the discharge channel is set here to make it more convenient to accommodate the influx of waste chips there, thereby enhancing the chip removal effect; the cutter head flow channel openings connected to the inlet flow channel and the liquid inlet flow channel are both opened on the side wall of the cutter head in order to have a more sufficient cooling effect on the cutter head. At the same time, the cutter head flow channel openings of the two channels are not easily blocked by a large amount of stirred waste chips and liquid, thereby ensuring normal chip removal.

[0028] Furthermore, it also includes:

[0029] The rotary joint is composed of an inner ring and an outer ring, wherein the inner ring is fixedly sleeved on the knife rod, and the outer ring is sleeved on the outer surface of the inner ring and is rotatably connected to the inner ring;

[0030] The outer cover is a cylindrical cover, which is sleeved on the outer ring surface of the rotary joint, and the outer cover extends toward the cutter head;

[0031] A pressing sheet, the protrusion of which is arranged on the inner wall of the outer cover, and the pressing sheet is in contact with the roller surface of the horizontal roller to be processed.

[0032] A rotary joint is sleeved on the cutter bar. More specifically, the rotary joint is arranged at the other end of the cutter bar away from the cutter head. The rotary joint is a structure composed of an inner ring and an outer ring that can rotate relative to each other. The inner ring is fixedly sleeved on the cutter bar, and the outer ring can rotate coaxially relative to the inner ring. In this scheme, an outer cover body is sleeved on the surface of the outer ring. The outer cover body is cylindrical, and its length direction extends horizontally in the direction of the cutter head. During the hole processing process, the outer cover body will cover the outside of one end of the horizontal roller. A pressing sheet is formed on the inner wall of the outer cover body. During the hole processing, the pressing sheet contacts the horizontal roller to be processed, thereby causing the outer cover body to rotate with the rotation of the horizontal roller, and then the outer ring of the rotary joint is also rotating. In this way, the inner ring is kept in a relatively stable stress state, and then the cutter bar is stably supported, and the vibration during the processing is reduced, thereby improving the processing speed, and avoiding the situation where the cutter bar is damaged by vibration, ensuring the improvement of processing efficiency and hole processing quality, thereby improving the manufacturing speed of the horizontal roller, and ensuring its manufacturing delivery period.

[0033] Furthermore, the pressing piece is movably connected to the inner wall of the outer cover body, and the pressing piece moves radially along the outer cover body.

[0034] A pressing plate is arranged to be movably connected to the inner wall of the outer cover, thereby ensuring that the pressing plate is in contact with the roller surface of the horizontal roller to stabilize the knife rod even when processing horizontal rollers with different roller diameters, thereby increasing the application scope of the device and facilitating the manufacturing and processing of various horizontal rollers.

[0035] Furthermore, it also includes an anti-vibration mechanism, a protrusion of which is arranged on the side wall of the cutter head, and the top of the anti-vibration mechanism is in contact with the hole wall of the horizontal roller to be processed.

[0036] The anti-vibration mechanism is formed on the side wall of the cutter head and protrudes from the side wall of the cutter head, and the top of the anti-vibration mechanism contacts the hole wall of the horizontal roller to be processed. After the cutter head is inserted into the hole, the blade on the cutter head contacts the inner wall of the hole for turning during the rotation of the horizontal roller. At this time, the top of the anti-vibration mechanism contacts the inner wall of the hole, thereby limiting the tendency of the cutter head and tool rod to vibrate during the processing and avoiding the occurrence of vibration, thereby ensuring the processing effect of the horizontal roller hole.

[0037] Furthermore, the anti-vibration mechanism includes a gasket, a spring and a fixing bolt, one end of the spring is fixedly connected to the side wall of the cutter head; the fixing bolt passes through the gasket to fix the gasket to the other end of the spring; the top of the gasket contacts the hole wall of the horizontal roller to be processed.

[0038] The anti-vibration mechanism composed of a gasket, a spring and a fixing bolt can be flexibly placed in the hole when processing different hole diameters, and the top of the gasket is pressed against the wall of the hole to be processed under the action of the spring rebound, ensuring the applicability of the cutter head under multiple working conditions and the stability of the anti-vibration effect.

[0039] Furthermore, the anti-vibration mechanism also includes a limiting groove, which is a groove opened on the side wall of the cutter head. The size of the limiting groove matches the gasket, and the limiting groove is opened at a position corresponding to the gasket.

[0040] By setting a limit groove, the gasket can be compressed into the limit groove, thereby limiting the tendency of the gasket to move in other directions, and only stably resting on the inner wall of the hole to be processed under the action of elastic force, further ensuring the stability of the cutter head during processing, ensuring the anti-vibration effect, and improving the processing efficiency of the horizontal roller.

[0041] Furthermore, the anti-vibration mechanism is provided in multiple pieces and is evenly arranged in the circumferential direction of the side wall of the cutter head;

[0042] There are a plurality of pressing sheets, which are evenly arranged in the circumferential direction of the inner wall of the outer cover.

[0043] Multiple anti-vibration mechanisms and pressure plates are provided, and are evenly arranged circumferentially. The purpose of the even arrangement is to ensure that the load and support force on the device are uniform during operation. The anti-vibration effect is further enhanced by arranging multiple anti-vibration mechanisms and pressure plates, ensuring that the device can quickly and effectively process horizontal rollers.

[0055] (10) The high-efficiency processing device for the horizontal roller of the universal rolling mill of the present invention eliminates the limitation of the processing speed caused by waste chips and processing overheating through the cooling and chip removal system, and eliminates the adverse effects of vibration at the tool rod and the tool head through the pressing plate and anti-vibration mechanism.

[0069] The present invention is further described below in conjunction with specific embodiments and drawings.

[0070] Example 1

[0071] like Figure 1 and Figure 2 As shown, the universal rolling mill horizontal roll high-efficiency processing device of this embodiment includes:

[0072] Tool bar 1;

[0073] A cutter head 2 connected to one end of the cutter bar 1;

[0074] Also included is a cooling and chip removal system 3, which includes:

[0075] The channel 30 is opened on the cutter bar 1 and the cutter head 2 along the length direction of the cutter bar 1;

[0076] A cutter head flow channel opening 301 is provided on the surface of the cutter head 2 and is connected to the channel 30 at one end of the cutter head 2;

[0077] A knife bar flow channel opening 302 is provided on the surface of the knife bar 1 toward the inside, and is connected with the channel 30 at one end of the knife bar 1;

[0078] The number of the channels 30 is multiple.

[0079] When machining long holes at the axis position of the horizontal roller, a longer tool rod 1 is required to support the tool head 2 to ensure that a sufficient hole depth can be machined. When machining long holes of the horizontal roller, the tool rod 1 is usually fixed, and the horizontal roller quickly rotates around its axis and moves toward the tool rod 1 to machine the long hole at the axis. Since the hole machined at the axis of the horizontal roller is not a through hole, as the machining depth increases, the waste chips generated during machining will be retained in the hole. Long-term accumulation will affect the normal machining operation, resulting in poor machining quality, damage to the machining tool head 2, vibration and fracture of the tool rod 1 and other adverse effects. Therefore, it is necessary to promptly remove the waste chips in the hole. Now, the hole machining is usually stopped, and the waste chips are blown out after the tool head 2 is withdrawn, which affects the machining efficiency. In addition, during the machining process, the contact between the tool head 2 and the hole wall will generate heat, and the heat in the hole is not easy to dissipate. The tool head 2 is prone to overheating and damage. The above factors limit the speed of horizontal roller hole machining, affect the overall manufacturing speed of the horizontal roller, and cannot guarantee the delivery period. In view of this, the present application makes improvements to the structure of the machining device:

[0080] The tool rod 1 is a slender rod, which is assembled on the machine tool. The overall shape of the cutter head 2 is the same as that of the cutter head in the prior art. The blade 21 is fixed to the end of the cutter head 2. A connecting end 22 is provided at the other end of the cutter head 2. The cutter head 2 is connected to the tool rod 1 through the connecting end 22. The cutter head 2 and the tool rod 1 of this embodiment are detachably connected. The connecting end 22 is a threaded rod formed by a protruding end. A threaded hole is correspondingly provided at the end of the tool rod 1. The detachable connection structure can facilitate the replacement of the cutter head 2. A cooling and chip removal system 3 is provided in this embodiment. A plurality of channels 30 are provided in the tool rod 1 and the cutter head 2 along the length direction of the tool rod 1. The two ends of the channels are respectively connected to the cutter head flow channel opening 301 and the tool rod flow channel opening 302. During the processing, since the tool rod 1 is stationary Without moving, a cooling medium such as coolant or compressed gas can be poured into the channel 30 through the tool bar flow channel opening 302. The poured cooling medium flows out from the tool head flow channel opening 301 located at the tool head 2 through the channel 30, firstly effectively cooling the tool head 2 to prevent it from being overheated and damaged. At the same time, the flowing coolant will also promptly wash away the waste chips generated by the processing to prevent excessive accumulation of waste chips in the hole, thereby saving the time for special blowing and chip removal, and there is no need to deliberately control the processing speed to prevent overheating, which greatly improves the processing efficiency, thereby effectively shortening the manufacturing time of the horizontal roller and achieving the purpose of efficiently manufacturing the horizontal roller. At the same time, the timely removal of waste chips can also effectively avoid the vibration of the tool head 2 and the tool bar 1 during the processing, thereby improving the surface processing quality of the hole wall.

[0081] Example 2

[0082] like Figure 1 , Figure 2 and Figure 3 As shown, the high-efficiency processing device for horizontal rolls of a universal rolling mill of this embodiment is further improved on the basis of embodiment 1, and the number of the channels 30 is three, including:

[0083] A chip removal channel 310 is provided in the middle of the tool bar 1 and the tool head 2 along the length direction of the tool bar 1;

[0084] An inlet channel 320 is provided beside the chip removal channel 310 along the length direction of the tool bar 1, and compressed gas flows through the inlet channel 320;

[0085] The liquid inlet channel 330 is opened beside the chip removal channel 310 along the length direction of the tool rod 1, and the cooling liquid flows through the liquid inlet channel 330.

[0086] During the hole processing, the horizontal roller is pushed toward the tool bar 1, and the blade 21 on the tool head 2 contacts the hole wall for processing. During the processing, more waste chips will be gathered in front of the tool head 2 away from the end face of the tool bar 1. This part of the waste chips cannot be quickly discharged only by flushing with the cooling medium. In view of this, the present embodiment further improves the structure of the cooling and chip removal system 3:

[0087] The present embodiment is provided with three channels 30, wherein the chip removal channel 310 is arranged in the middle, the inlet channel 320 and the liquid inlet channel 330 are located beside the chip removal channel 310, wherein the inlet channel 320 is used to introduce compressed gas, and the liquid inlet channel 330 is used to introduce coolant. During the machining process, the coolant flows through the liquid inlet channel 330 and flows out from the cutter head 2. While cooling the cutter head 2, the coolant will gradually fill the gap between the cutter head 2 and the hole wall and contact and mix with the retained waste chips, while the compressed gas flows through the inlet channel 320 and flows out from the cutter head 2, which can also cool the cutter head 2 and fully stir the inside of the hole. The coolant can make the waste chips deposited in the hole fully mixed with the coolant, and the chip removal channel 310 does not discharge the medium into the hole. As the channel closest to the mixed liquid at the tool head 2 and with the lowest pressure, the coolant overflowing from the liquid inlet channel 330, the gas overflowing from the inlet channel 320, and the waste chips fully mixed with the coolant will flow into the chip removal channel 310. Under the condition of continuously pressurizing and replenishing the medium in the liquid inlet channel 330 and the inlet channel 320, the mixture and liquid flowing into the chip removal channel 310 will be discharged along the tool rod channel port 302 connected to the chip removal channel 310, thereby completing the timely, rapid and thorough discharge of the waste chips.

[0088] Example 3

[0089] The universal rolling mill horizontal roller efficient processing device of this embodiment is further improved on the basis of Embodiment 2, and the air inlet channel 320 and the liquid inlet channel 330 are symmetrically arranged.

[0090] The air inlet channel 320 and the liquid inlet channel 330 are symmetrically arranged on both sides of the chip removal channel 310 to ensure the uniformity of the mass distribution of the device in terms of geometric shape. During rapid hole processing, vibration will not be generated due to uneven mass distribution of the tool rod 1 or the tool head 2, causing damage to the device and affecting the smooth progress of the processing.

[0091] Example 4

[0092] like Figure 3 As shown, the high-efficiency processing device for the horizontal roll of a universal rolling mill of this embodiment is further improved on the basis of Embodiment 3, and the cutter head flow channel opening 301 connected with the chip removal flow channel 310 is opened on the end surface of the cutter head 2 away from the cutter rod 1;

[0093] The cutter head flow channel opening 301 communicating with the inlet flow channel 320 and the liquid inlet flow channel 330 is disposed on the side wall of the cutter head 1 .

[0094] In this embodiment, the cutter head flow channel opening 301 connected to the chip removal channel 310 is arranged on the end face of the cutter head 2 away from the tool rod 1. The purpose is to locate the space in front of the end face of the cutter head 2 away from the tool rod 1 where waste chips are most easily accommodated, and it is also the place where waste chips are difficult to be removed by ordinary flushing. The cutter head flow channel opening 301 of the discharge channel 310 is arranged here to make it more convenient to accommodate the influx of waste chips there, thereby enhancing the chip removal effect; the cutter head flow channel opening 301 connected to the inlet flow channel 320 and the liquid inlet flow channel 330 are both opened on the side wall of the cutter head 1, in order to have a more sufficient cooling effect on the cutter head 2. At the same time, the cutter head flow channel openings 301 of the two channels are not easily blocked by a large amount of stirred waste chips and liquid, thereby ensuring normal chip removal.

[0095] Example 5

[0096] like Figure 1 As shown, the high-efficiency processing device for horizontal rolls of a universal rolling mill of this embodiment is further improved on the basis of embodiments 1 to 4, and further includes:

[0097] The rotary joint 4 is composed of an inner ring and an outer ring, wherein the inner ring is fixedly sleeved on the knife rod 1, and the outer ring is sleeved on the outer surface of the inner ring and is rotatably connected to the inner ring;

[0098] The outer cover 5 is a cylindrical cover, which is sleeved on the outer ring surface of the rotary joint 4, and the outer cover 5 extends toward the cutter head 2;

[0099] A pressing sheet 50, whose protrusion is arranged on the inner wall of the outer cover body 5, is in contact with the roller surface of the horizontal roller to be processed.

[0100] Waste chips are factors that affect processing efficiency. After eliminating the influence of waste chip accumulation, the processing speed of the horizontal roller is improved. However, with the increase in processing speed, the vibration of the tool rod 1 and the tool head 2 increases when processing long holes. The vibration can easily cause the tool rod 1 or the tool head 2 to break and be damaged, and will affect the processing quality of the hole wall. Although reducing the processing speed can reduce the frequency of vibration, it will limit the processing speed of the horizontal roller. In view of this, the present embodiment is provided with a rotary joint 4 on the tool rod 1. More specifically, the rotary joint 4 is arranged at the other end of the tool rod 1 away from the tool head 2. The rotary joint 4 is a structure composed of an inner ring and an outer ring that can rotate relative to each other. The inner ring is fixedly sleeved on the tool rod 1, and the outer ring can rotate coaxially relative to the inner ring; the outer ring of the present embodiment is provided on the outer ring surface The outer cover body 5 is sleeved on the surface, and the outer cover body 5 is cylindrical, and its length direction (i.e., axial direction) extends horizontally toward the cutter head 2. During the hole processing process, the outer cover body 5 will cover the outside of one end of the horizontal roller; a pressing plate 50 is formed on the inner wall of the outer cover body 5, and during the hole processing process, the pressing plate 50 contacts the horizontal roller to be processed, thereby causing the outer cover body 5 to rotate with the rotation of the horizontal roller, and then the outer ring of the rotary joint 4 also rotates, thereby keeping the inner ring in a relatively stable stress state, thereby allowing the tool rod 1 to be stably supported, reducing vibration during the processing process, thereby improving the processing speed, and avoiding the tool rod from being damaged by vibration, thereby improving the processing efficiency and hole processing quality, thereby increasing the manufacturing speed of the horizontal roller and ensuring its manufacturing delivery deadline.

[0101] Example 6

[0102] like Figure 1 As shown, the high-efficiency processing device for horizontal rollers of a universal rolling mill of this embodiment is further improved on the basis of Embodiment 5, and the pressing plate 50 is movably connected to the inner wall of the outer cover body 5, and the pressing plate 50 moves radially along the outer cover body 5.

[0103] A universal rolling mill requires horizontal rollers with different roller diameters when processing different products. For horizontal rollers with different roller diameters, the present embodiment provides a pressure plate 50 that can be movably connected to the inner wall of the outer cover 5. Therefore, even when processing horizontal rollers with different roller diameters, it can ensure that the pressure plate 50 is in contact with the roller surface of the horizontal roller to stabilize the knife rod 1, thereby increasing the scope of application of the present device and facilitating the manufacturing and processing of various horizontal rollers.

[0104] Furthermore, the movable connection structure of the pressing plate 50 of the present embodiment includes a telescopic rod 500 and an elastic member 501 protruding from the inner wall of the outer cover body 5. The elastic member 501 can be a component with elastic recovery such as a spring. One end of the telescopic rod 500 is fixedly provided on the inner wall of the outer cover body 5, and the other end is fixedly connected to the pressing plate 50. One end of the elastic member 501 is fixedly provided on the inner wall of the outer cover body 5, and the other end is fixedly connected to the pressing plate 50. Under the limitation of the telescopic rod 500, the pressing plate 50 can only move radially of the outer cover body 5. Under the action of the elastic member 501, the pressing plate 50 has the ability to flexibly expand and contract to adapt to the roller diameter of the horizontal roller, thereby ensuring that the pressing plate 50 can stably contact the roller surface of each horizontal roller, stably drive the outer cover body 5 to rotate, and then ensure stable support for the tool rod 1, and ensure that the hole processing can be carried out quickly.

[0105] Example 7

[0106] like Figure 2 and Figure 3 As shown, the high-efficiency processing device for horizontal rollers of a universal rolling mill of this embodiment is further improved on the basis of Example 6, and also includes an anti-vibration mechanism 20, a protrusion of which is arranged on the side wall of the cutter head 2, and the top of the anti-vibration mechanism 20 is in contact with the hole wall of the horizontal roller to be processed.

[0107] During the processing of the horizontal roller hole, the vibration at the cutter head 2 of the processing device is also one of the factors that affect the processing efficiency and quality. In response to the vibration at the cutter head 2, an anti-vibration mechanism 20 is provided in this embodiment. The anti-vibration mechanism 20 is formed on the side wall of the cutter head 2 and protrudes from the side wall of the cutter head 2. The top of the anti-vibration mechanism 20 contacts the hole wall of the horizontal roller to be processed. After the cutter head 2 is inserted into the hole, during the rotation of the horizontal roller, the blade 21 on the cutter head 2 contacts the inner wall of the hole for turning. At this time, the top of the anti-vibration mechanism 20 contacts the inner wall of the hole, thereby limiting the vibration tendency of the cutter head 2 and the tool rod 1 during the processing, avoiding the occurrence of vibration, thereby ensuring the processing effect of the horizontal roller hole. Under the cooperation of the anti-vibration mechanism 20 and the pressing plate 50, the processing device is fixed from the tail end of the cutter head 1 and the tool rod 2 respectively, and the fixation is completed with the cooperation of the horizontal roller to be processed, which greatly reduces the vibration of the tool rod during the hole processing, thereby increasing the hole processing speed without worrying about the influence of vibration, greatly shortening the horizontal roller hole processing time, and increasing the horizontal roller manufacturing speed.

[0108] Example 8

[0109] like Figure 3 and, Figure 4 Figure 5As shown, the high-efficiency processing device for horizontal rollers of universal rolling mills of this embodiment is further improved on the basis of Example 7, and the anti-vibration mechanism 20 includes a gasket 201, a spring 202 and a fixing bolt 203, one end of the spring 202 is fixedly connected to the side wall of the cutter head 2; the fixing bolt 203 passes through the gasket 201 to fix the gasket 201 to the other end of the spring 202; the top of the gasket 201 is in contact with the hole wall of the horizontal roller to be processed.

[0110] The anti-vibration mechanism 20 composed of a gasket 201, a spring 202 and a fixing bolt 203 can be flexibly placed in the hole when processing different hole diameters, and the top of the gasket 201 is against the wall of the hole to be processed under the rebound action of the spring 202, ensuring the applicability of the cutter head 2 under multiple working conditions and the stability of the anti-vibration effect.

[0111] Example 9

[0112] like Figure 3 As shown, the high-efficiency processing device for horizontal rollers of a universal rolling mill of this embodiment is further improved on the basis of embodiments 1 to 8, and the anti-vibration mechanism 20 also includes a limit groove 200, which is a groove opened on the side wall of the cutter head 2, and the size of the limit groove 200 matches the gasket 201, and the limit groove 200 is opened at the position corresponding to the gasket 201.

[0113] By setting the limit groove 200, the gasket 201 can be compressed into the limit groove 200, thereby limiting the tendency of the gasket 201 to move in other directions, and only stably resting on the inner wall of the hole to be processed under the action of elastic force, further ensuring the stability of the cutter head 2 during the processing, ensuring the anti-vibration effect, and improving the processing efficiency of the horizontal roller.

[0114] Furthermore, a clearance space 2010 is provided at the top of the gasket 201 of the anti-vibration mechanism 20 , and a fixing bolt 203 passes through the clearance space 2010 to fix the gasket 201 on the spring 202 , and a bolt head of the fixing bolt 203 is sunk in the clearance space 2010 .

[0115] Figure 4 The figure shows one structure of the anti-vibration mechanism 20 of the present invention, which is composed of a gasket 201, a spring 202 and a fixing bolt 203. A groove-like concession 2010 is provided in the middle of the top of the gasket 201. The gasket 201 is fixed to the top of the spring 202 by the fixing bolt 203. The fixing bolt 203 passes through the gasket 201 at the concession 2010 to fix the gasket 201 and the spring 202. The bottom end of the spring 202 is fixed to the side wall of the cutter head 2. The spring 202 is arranged on the side wall of the cutter head 2 along the radial direction of the cutter head 2. The bottom of the screw of the fixing bolt 203 is provided with a spring interface 2030 for fixing the top of the spring 202. Figure 6 shown; through Figure 3The anti-vibration mechanism 20 shown allows the bull bit 201 to adaptively adjust its height position according to different hole sizes. When processing various types of water-cooling holes or other holes that need to be processed on the continuous casting roller, the anti-vibration mechanism 20 can be flexibly placed in the air, and under the rebound action of the spring 202, the top of the gasket 201 is against the wall of the hole to be processed, ensuring the anti-vibration effect and the wide application range of the tool of the present application. At the same time, the setting of the yield position 2010 can make the bolt head of the fixing bolt 203 sink into the yield position 2010, preventing the bolt head from directly contacting the inner wall of the hole to be processed, preventing direct contact from affecting the processing effect of the tool, and preventing the gasket 201 from being unable to fully contact the inner wall after direct contact to affect the anti-vibration effect.

[0116] Figure 5 Another structure of the anti-vibration mechanism 20 of the present invention is shown, which is composed of a gasket 201, a spring 202 and a fixing bolt 203. A countersunk hole-type concession 2010 is provided in the middle of the top of the gasket 201. The gasket 201 is fixed to the top of the spring 202 by the fixing bolt 203. The fixing bolt 203 passes through the gasket 201 at the countersunk hole-type concession 2010 to fix the gasket 201 and the spring 202. The bottom end of the spring 202 is fixed to the side wall of the cutter head 2. The spring 202 is arranged on the side wall of the cutter head 2 along the radial direction of the cutter head 2. The bottom of the screw of the fixing bolt 203 is provided with a spring interface 2030 for fixing the top of the spring 202. Figure 6 shown; through Figure 4 The anti-vibration mechanism 20 shown allows the bull bit 201 to adaptively adjust its height position according to different hole sizes. When processing various types of water-cooling holes or other holes that need to be processed on the continuous casting roller, the anti-vibration mechanism 20 can be flexibly placed in the air, and under the rebound action of the spring 202, the top of the gasket 201 is against the wall of the hole to be processed, ensuring the anti-vibration effect and the wide application range of the tool of the present application. At the same time, the setting of the yield position 2010 can make the bolt head of the fixing bolt 203 sink into the yield position 2010, preventing the bolt head from directly contacting the inner wall of the hole to be processed, preventing direct contact from affecting the processing effect of the tool, and preventing the gasket 201 from being unable to fully contact the inner wall after direct contact to affect the anti-vibration effect.

[0117] Furthermore, the top of the gasket 201 of the anti-vibration mechanism 20 is an arc-shaped protrusion 2011 .

[0118] The present embodiment improves the top shape of the gasket 201. The top of the gasket 201 is an arc-shaped protrusion 2011, thereby ensuring that the top of the gasket 201 can fully contact the inner wall of the hole during the processing, thereby ensuring the anti-vibration effect. At the same time, the arc-shaped surface after the protrusion also avoids scratching the inner wall of the hole, thereby ensuring the effective service life of the horizontal roller.

[0119] Example 10

[0120] The high-efficiency processing device for horizontal rolls of a universal rolling mill of this embodiment is further improved on the basis of embodiments 1 to 9, wherein a plurality of anti-vibration mechanisms 20 are provided and are evenly arranged in the circumferential direction of the side wall of the cutter head 2;

[0121] There are multiple pressing sheets 50 , which are evenly arranged around the inner wall of the outer cover 5 .

[0122] In this embodiment, multiple anti-vibration mechanisms 20 and pressing plates 50 are provided and are evenly arranged circumferentially. The purpose of the even arrangement is to ensure that the load and supporting force on the device are uniform during operation. By arranging multiple anti-vibration mechanisms 20 and pressing plates 50, the anti-vibration effect is further enhanced to ensure that the device can quickly and effectively process horizontal rollers.

[0123] The high-efficiency processing device for the horizontal roller of the universal rolling mill of this embodiment eliminates the limitations of waste chips and processing overheating on the processing speed through the cooling and chip removal system 3, and eliminates the adverse effects of vibration at the tool rod 1 and the tool head 2 through the pressing plate 50 and the anti-vibration mechanism 20. The cooling and chip removal system 3, the anti-vibration mechanism 20, and the pressing plate 50 cooperate with each other to eliminate the adverse factors that limit the processing speed of the horizontal roller holes, so that the horizontal roller can be processed efficiently without affecting the hole processing quality and damaging the processing device.

[0124] Embodiment 11

[0125] The high-efficiency processing method of the universal rolling mill horizontal roll of this embodiment comprises the following steps:

[0126] Rotate the horizontal roller to align the hole to be processed with the position of the cutter head 2, move the horizontal roller toward the position of the cutter bar 1, inject coolant into the liquid inlet channel 330 through the cutter bar channel opening 302 connected to the liquid inlet channel 330, and inject compressed gas into the inlet channel 320 through the cutter bar channel opening 302 connected to the inlet channel 320;

[0127] After the cutter head 2 enters the hole to be processed, the top of the gasket 201 of the vibration mechanism 20 contacts the hole wall, and the pressing sheet 50 on the outer cover 5 contacts the roller surface of the horizontal roller;

[0128] During the machining process, waste chips and mixed liquid flow out from the tool bar flow channel opening 302 which is connected to the chip removal flow channel 310 .

[0129] Through the method of this embodiment, there is no need to stop the chip removal operation or stop cooling during the horizontal roller hole processing, which greatly shortens the processing time. At the same time, it also eliminates the adverse factors that cause the tool rod 1 and the tool head 2 to vibrate, ensuring stable and effective processing of the holes when the horizontal roller rotates at high speed, ensuring an efficient horizontal roller manufacturing speed, and ensuring the delivery deadline.
