Description

Technical Field

[0002] The cold rolling mill is a process equipment that uses annular holes to cold roll rough pipes. The cold rolling mill has good billet opening performance and can also roll non-ferrous metal seamless pipes of ordinary precision. The biggest feature of the cold rolling mill is the high material utilization rate, and the precision and surface roughness are better than cold drawn pipes.

[0003] The cold rolling mill usually uses multiple rollers to continuously extrude the tube billet to reduce its outer diameter and inner diameter at the same time, and thin the wall thickness. The cold-rolled steel tube is then straightened and slit, and finally the surface is treated before the final quality inspection.

[0004] However, during the process of feeding and transmitting the tube billet toward the cold rolling mill, the protruding end of the tube billet is away from the transmission equipment. At this time, the protruding end of the tube billet cannot be well supported, and the tube billet may not be able to enter between the rollers or may collide with the rollers, causing the tube billet to be easily deformed and affecting the normal cold rolling operation. Therefore, it is necessary to provide a feeding support device for the cold rolling mill to solve the above problems.

[0040] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0041] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present application.

[0042] like Figure 1-Figure 3 As shown, the present application provides a feeding support device for a cold rolling tube mill, comprising two groups of fixed frames 5, between which multiple groups of cold rolling mechanisms 2 are arranged, the cold rolling mechanisms 2 are used to cold roll the steel tube, the cold rolling mechanisms 2 have an upper rolling roller 21 rotatably connected to the fixed frame 5 and a lower rolling roller 22 rotatably connected to the fixed frame 5, the lower rolling roller 22 is arranged directly below the upper rolling roller 21, and at the same time, a rolling groove 25 is opened in the middle of the surface of the upper rolling roller 21 and the lower rolling roller 22, and the rolling groove 25 is used to place the steel tube to be rolled;

[0043] In order to drive the upper roller 21 and the lower roller 22 to rotate simultaneously, a driving mechanism 1 is provided on one side of the cold rolling mechanism 2. The driving mechanism 1 has a driving tooth 11 fixedly installed on one side of the upper roller 21, and a driven tooth 12 is fixedly installed on one side of the lower roller 22. The driven tooth 12 is meshed with the driving tooth 11.

[0044] Since multiple groups of cold rolling mechanisms 2 are provided, in order to drive the multiple groups of cold rolling mechanisms 2, transmission teeth 13 are provided between the multiple groups of cold rolling mechanisms 2, and the transmission teeth 13 are meshed with the multiple groups of driven teeth 12. At the same time, a driving motor 16 is provided on the outer side of the transmission teeth 13 of one group, and the driving motor 16 has a driving shaft 14, and the driving shaft 14 is fixed at the axis center of the transmission teeth 13, and a motor frame 15 is fixedly installed on the outer side of the fixed frame 5, and the driving motor 16 is fixed on the motor frame 15, so as to ensure the operation stability of the driving motor 16.

[0045] In the present application, a transmission device (not shown) is provided on one side of the cold rolling mechanism 2, and the transmission device includes a mandrel limiting trolley, which is used to connect the mandrel and transmit the mandrel together with the tube to be rolled toward the tube rolling mill. The transmission device is a prior art and will not be described in detail here. It should be noted that the tube outlet height of the transmission device is consistent with the height of the rolling groove 25. Therefore, before cold rolling, the mandrel 23 is first inserted into the interior of the steel pipe, and then the steel pipe and the mandrel 23 are transmitted toward the cold rolling mechanism 2 through the transmission device and enter the rolling groove 25. At the same time, a material receiving trolley is provided at the discharge end of the tube rolling mill to facilitate the transportation of the rolled steel pipe to the next process.

[0046] like Figure 4-Figure 6 As shown, in order to prevent the protruding section of the tube blank transmitted to the cold rolling mechanism 2 from falling, a guiding mechanism 3 is arranged between the cold rolling mechanism 2 and the transmission device, and the guiding mechanism 3 has a base 31 arranged at one side of the bottom end of the fixed frame 5, and a slide rail 32 is fixedly installed on the upper end of the base 31, and a push block 34 is arranged above the slide rail 32, and a transmission wheel 342 is fixedly installed on the upper end of the push block 34, and the transmission wheel 342 is used to support and transmit the protruding tube blank;

[0047] At the same time, a matching plate 341 is fixedly installed at the rear end of the push block 34, and a matching groove 321 is fixedly installed at the upper end of one side of the slide rail 32. The matching plate 341 is slidably connected to the inside of the matching groove 321, so that the push block 34 can move vertically.

[0048] In order to better control the position of the transmission wheel 342, a slider 33 is slidably connected in the slide rail 32, and the slider 33 is located below the push block 34, and a top plate 331 is fixedly installed on the upper end of the slider 33, and a lower inclined surface 332 is tilted downward on one side of the upper end of the top plate 331, and an upper inclined surface 343 is tilted upward on one end of the push block 34 away from the lower inclined surface 332, and the outer end angles of the upper inclined surface 343 and the lower inclined surface 332 are set as arc angles, so that it is convenient for the lower inclined surface 332 to enter the upper inclined surface 343 and cooperate with the upper inclined surface 343 to push the push block 34 to move up and down;

[0049] In addition, a driving member 35 is provided on one side of the slider 33. The driving member 35 has a stand 352 installed on one side of the base 31. A driving cylinder 351 is fixedly installed on the upper end of the stand 352. The driving cylinder 351 has an output shaft 353. The other end of the output shaft 353 is fixed to the end of the slider 33 away from the lower inclined surface 332. Therefore, starting the driving cylinder 351 can drive the slider 33 to slide in the slide rail 32. When the slider 33 slides, the push block 34 can be pushed to slide in the matching groove 321, thereby realizing the position adjustment of the push block 34.

[0050] like Figure 4 and Figure 6 As shown, in order to ensure the transmission stability of the tube blank and adapt to tube blanks of different sizes, a supporting mechanism 4 is further provided on both sides of the transmission wheel 342. The supporting mechanism 4 has a supporting plate 41 and a mounting plate 42 respectively fixed to the inner side of the fixing frame 5. The inner end of the supporting plate 41 is rotatably connected to a first supporting frame 43. The first supporting frame 43 is set to be obtuse-angled. The lower end of the first supporting frame 43 is rotatably connected to a first adjusting wheel 47. At the same time, adjusting inclined surfaces 344 are relatively opened on both side ends of the push block 34. The first adjusting wheel 47 is attached to the adjusting inclined surface 344, and the upper end of the first supporting frame 43 is rotatably connected to a first transmission wheel 45. Therefore, when the push block 34 moves up and down, the first adjusting wheel 47 can slide on the adjusting inclined surface 344, thereby adjusting the orientation of the first supporting frame 43.

[0051] In addition, the outer end of the mounting plate 42 is rotatably connected to a second supporting frame 44, which is also set to be obtuse-angled and arranged opposite to the first supporting frame 43, and the lower end of the second supporting frame 44 is rotatably connected to a second adjusting wheel 48, which is attached to the adjusting inclined surface 344, and the upper end of the second supporting frame 44 is rotatably connected to a second transmission wheel 46. Similarly, when the second adjusting wheel 48 slides on the adjusting inclined surface 344, the orientation of the second supporting frame 44 can be adjusted;

[0052] In the present application, a first sleeve shaft 431 is fixedly installed on the outer side of the lower end of the first supporting frame 43, and a second sleeve shaft 441 is fixedly installed on the outer side of the second supporting frame 44, and a tension spring 49 is fixedly installed between the first sleeve shaft 431 and the second sleeve shaft 441. It should be noted that the first adjustment wheel 47 and the second adjustment wheel 48 are initially located at the upper end of the adjustment inclined surface 344, so the tension spring 49 is in a stationary state at this time.

[0053] In summary, when the tube to be rolled is transmitted to the cold rolling mechanism 2, the driving cylinder 351 is started to push the slider 33 to slide outward. In this process, the push block 34 can be pushed upward by the contact between the lower inclined surface 332 and the upper inclined surface 343, and slide along the matching groove 321, driving the transmission wheel 342 to support the tube to prevent it from falling.

[0054] When the push block 34 slides upward, the first adjusting wheel 47 and the second adjusting wheel 48 will slide downward along the adjusting inclined surface 344, and the tension spring 49 will be stretched, and at the same time, the first supporting frame 43 and the second supporting frame 44 will be driven to rotate until the first transmission wheel 45 and the second transmission wheel 46 are attached to the surface of the tube blank, thereby preventing the tube blank from shaking left and right, ensuring the transmission efficiency, and adapting to tube blanks of different lengths;

[0055] When the transmission is completed and not in use, the driving cylinder 351 is started and retracted, so that the slider 33 slides back to the original position. At this time, the push block 34 has no thrust and slides down, and the tension spring 49 contracts to drive the first adjustment wheel 47 and the second adjustment wheel 48 to reset, thereby completing the reset of all devices;

[0056] Therefore, in the process of conveying the tube billet to the cold rolling mill, since the protruding end of the tube billet is away from the transmission equipment, the protruding end of the tube billet can support the tube billet well due to the support of the guiding mechanism 3 below and the supporting mechanism 4 on both sides, thereby preventing the tube billet from shaking during transmission and failing to enter the rolling roller well, preventing the tube billet from deformation, and ensuring normal cold rolling operation.

[0057] The above description is only the preferred embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
