Compared with the traditional process of casting a steel billet first, heating it in a heating furnace and then rolling it, it has the advantages of simplifying the process, improving labor conditions, increasing metal recovery, saving energy, improving the quality of the continuous casting billet, and facilitating mechanization and automation.

The rollers on the hot rolling mill rotate at high speed, and two symmetrical rollers cooperate to roll the aluminum-titanium-boron alloy rod. The aluminum-titanium-boron alloy rod will exert a reaction force on the rollers. Therefore, the contact part between the mechanism supporting the rollers and the roller shaft is subjected to high pressure, and sufficient lubrication is required to ensure the smooth and efficient rotation of the rollers.

The water in the water tank flows down to the water inlet pipe 9, and then flows into the heat exchange tube cavity 7 through a ring box 8. The water takes away the heat in the roller shaft 3 and the roller 4, and then transfers it to the water outlet pipe 10 through another ring box 8, and then is discharged through the interceptor 16.

The oil nozzle box 41 is distributed in a fan-shaped groove on the L-shaped shaft seat 5, and the oil nozzle box 41 has a plurality of small holes arranged in an arc to face the outer wall of the roller shaft 3. One end of the screw rod 39 is sleeved in a slot hole formed on the bottom plate of the tank box 37, so that the screw rod 39 rotates in situ.

[0041] The slow-advance group 12 includes a mainspring 44 fixedly sleeved on the new moving shaft 29, a limiting tube 45 fixedly sleeved outside the mainspring 44, a C-shaped column 42 fixedly sleeved outside the limiting tube 45, and a sub-plate 43 fixed on one side of the limiting tube 45. The new moving shaft 29 is movably sleeved in a circular hole opened in the middle of the sub-plate 43, and one end of the screw rod 39 is meshed and transmission-connected with the outer gear ring arranged on the sub-plate 43 through a fixed gear.

[0042] The roulette device 14 includes an integrated plate frame 50 with one end resting on the limiting cylinder 45, a wheel axle 48 supported at the other end of the integrated plate frame 50, a tail control worm 49 and a lifting shaft 51 supported on the integrated plate frame 50, and a wheel 46 fixed at one end of the wheel axle 48, the other end of the wheel axle 48 is meshed and connected with the helical teeth on the tail control worm 49 through a fixed gear, one end of the lifting shaft 51 is meshed and connected with the bevel gear fixed at one end of the tail control worm 49 through a fixed bevel gear, the other end of the lifting shaft 51 is meshed and connected with the gear fixed on the vertical shaft 24 through a fixed gear, the end of the integrated plate frame 50 intercepts one end of the C-shaped column 42 by setting an inclined surface, and the wheel axle 48, the tail control worm 49 and the lifting shaft 51 are respectively movably sleeved in different through holes opened on the integrated plate frame 50.

[0043] The roulette device 14 also includes a cover pressure spring piece 47, which is slidably passed through the inner hole of the square tube fixed on the L-shaped shaft seat 5 by setting a straight plate on the integrated plate frame 50, and one end of the cover pressure spring piece 47 is fixed on the square tube, and the other end of the cover pressure spring piece 47 is placed on the straight plate end of the integrated plate frame 50.

[0044] The interceptor 16 includes a round cap box 54 fixed on the L-shaped shaft seat 5, a lead-out pipe 55 fixedly connected to one end of the round cap box 54, a water plate 52 sliding through the inner hole of a flat cylinder fixed on one side of the round cap box 54, and an outer support spring 53 connected between the water plate 52 and the flat cylinder of the round cap box 54. The other end of the round cap box 54 is connected to the water outlet pipe 10, the wheel 46 is in contact with the convex arc surface of one end of the water plate 52, and the outer edge of the wheel 46 is also provided with an arc plate groove into which the water supply plate 52 sinks, and the other end of the water plate 52 blocks the port of the water outlet pipe 10.

[0045] The machine tool 2 is a machine tool of the prior art. The motor arranged in the machine tool 2 drives the roller shaft 3 to rotate. During the process, the roller shaft 3 also drives the neck shaft 21, and then drives the slow feed group 12 through the first speed reduction worm 23. Next, the second speed reduction worm 19 drives the new moving gear 27, and then drives the horizontal shaft 25 through the side shaft 28, and then drives the lifting shaft 51 through the vertical shaft 24. The rear tail control worm 49 drives the wheel shaft 48, and the wheel disc 46 rotates slowly. Every time the wheel disc 46 rotates one circle, the water plate 52 will have a fixed stage to sink into the arc plate groove of the wheel disc 46, so that the water plate 52 can telescope relative to the round cap box 54. The water plate 52 is inserted into the round cap box 54, and the water plate 52 will block the port of the water outlet pipe 10. The reverse movement of the water plate 52 will open the port of the water outlet pipe 10. Therefore, the flow of water in the heat exchange tube cavity 7 is intermittent flow, leaving enough time for the water flow to absorb heat.

[0046] The heat on the roller 4 is transferred to the roller shaft 3, and the grease on the surface of the roller shaft 3 will fail faster. The present invention uses a slip detector 15 to detect the lubrication degree of the outer wall of the roller shaft 3. If the outer wall of the roller shaft 3 is dry, it will be detected by the slip detector 15, and the subsequent lubrication supply mechanism will be automatically triggered. Specifically, the rotation of the dry outer wall of the roller shaft 3 will scrape the rubber column 36, and the rubber column 36 moves in the fan-shaped groove of the L-shaped shaft seat 5. The rubber column 36 drives the S-shaped spring piece 35, which in turn causes the L-shaped limit column 32 to move, and then causes the double-control gear 30 to move axially through the double-control shaft 31. Figure 8 and Fig. 9 After the double-control gear 30 moves axially, it contacts and meshes with the new moving gear 27 to establish a transmission channel for the lubrication mechanism. Specifically, the new moving gear 27 and the new moving shaft 29 rotate synchronously, causing the spring 44 to contract and accumulate force. At this time, the integrated plate frame 50 is covered and pressed by the cover spring 47 to support one end of the C-shaped column 42, limiting the rotation of the limit cylinder 45. After the spring 44 is fully charged, it will cause the C-shaped column 42 to break through the interception. The spring 44 releases the force, and the limit cylinder 45 drives the sub-plate 43 to rotate. Then the screw rod 39 rotates to cause the push plate 38 to slide in the slot box 37. The push plate 38 pushes the grease. The grease in the slot box 37 is slowly discharged into the oil pipe 40, and is discharged from the oil nozzle box 41 and smeared on the outer wall of the rotating roller shaft 3 to lubricate the contact surface between the roller shaft 3 and the L-shaped shaft seat 5, eliminating the dryness problem on the roller shaft 3.

[0047] Since the grease delivery and application process is slow, the lubrication process lasts for a period of time. In order to prevent the frictional heat between the roller shaft 3 and the L-shaped shaft seat 5 before the lubrication is completed, the flow of water in the heat exchange tube cavity 7 needs to be strengthened to cool down. In addition, the lubrication failure problem on the roller shaft 3 may also come from the overheated roller 4 transferring heat to the roller shaft 3, so that the heat erosion causes the grease to fail prematurely. Therefore, in the lubrication supply stage of the present invention, the water flow in the heat exchange tube cavity 7 is strengthened, that is, the intermittent flow is changed to continuous flow, specifically Fig.11The C-shaped column 42 in the middle rotates counterclockwise, and the end of the C-shaped column 42 lifts up the integrated plate frame 50. Fig.12 The integrated plate frame 50 in the heat exchanger rises to drive the wheel shaft 48, and then the rotating wheel disc 46 rises. After the wheel disc 46 rises, it no longer presses the water plate 52. The outer support spring piece 53 pushes the water plate 52 to be pulled out of the round cap box 54, and then the water plate 52 no longer blocks the port of the water outlet pipe 10. In this way, the water delivery path is no longer blocked, and the water flow in the heat exchange tube cavity 7 will continue to flow during the lubrication supply stage.

[0048] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
