DETAILED DESCRIPTION

[0026] The following is a further description of the specific implementation of the present invention in conjunction with the accompanying drawings and embodiments. The following embodiments are only used to more clearly illustrate the technical solution of the present invention, and cannot be used to limit the protection scope of the present invention.

[0027] "Top surface", "bottom" and "underside" are based on the normal use status of the seamless stainless steel pipe rolling equipment and are only for the convenience of describing the present invention and simplifying the description. They do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, they cannot be understood as a limitation on the present invention.

[0028] like Figure 1-3 As shown, a seamless stainless steel pipe rolling equipment includes a main body 1, the main body 1 has a rolling channel 101; a discharging mechanism 2, which is arranged at the discharging port of the rolling channel 101; the extension direction along the rolling channel 101 is a first direction, the discharging mechanism 2 includes a support frame 201 and two translation platforms 203, the translation platforms 203 are arranged on the top of the support frame 201 for horizontal sliding perpendicular to the first direction, and a plurality of support rollers 204 are arranged on the two translation platforms 203, and the support rollers 204 are distributed at equal intervals along the first direction, and the support rollers 204 located on different translation platforms 203 are staggered and distributed in a V-shape.

[0029] The above-mentioned rolling equipment is suitable for cold rolling processing of seamless stainless steel pipes. When in use, the billet passes through the rolling channel 101 of the main body 1, and the rollers and mandrels inside the main body 1 roll the billet. After rolling, the stainless steel pipe comes out of the discharge port of the rolling channel 101 and arrives at the discharge mechanism 2. The seamless stainless steel pipe is supported by each support roller 204, so that the seamless stainless steel pipe inside and outside the rolling channel 101 maintains a coaxial state, thereby reducing the probability of bending or wearing of the stainless steel pipe during the rolling process, and improving the quality of the seamless stainless steel pipe processed by the rolling equipment.

[0030] In the rolling equipment, a group of support rollers 204 are respectively arranged on the two translation platforms 203, and the two groups of support rollers 204 are distributed in a V shape. When the stainless steel pipe is located between the two groups of support rollers 204, the V-shaped structure can play a good supporting and limiting role for the stainless steel pipe, thereby improving the stability of the support for the stainless steel pipe; the two groups of support rollers 204 are driven by the translation platform 203 to move independently. When the two groups of support rollers 204 move in the same direction, the positions of the two groups of support along the perpendicular direction can be adjusted, thereby adjusting the support position of the stainless steel pipe; when the two groups of support rollers 240 move toward each other, the position of the intersection of the two groups of support rollers is increased, thereby increasing the support height of the stainless steel pipe; when the two groups of support rollers 240 move away from each other, the position of the intersection of the two groups of support rollers is lowered, thereby decreasing the support height of the stainless steel pipe; through the above adjustment, the discharging mechanism 2 can be suitable for supporting stainless steel pipes of different diameters, thereby improving the practicality of the rolling equipment.

[0031] A further improvement is, Figure 2 , 4 As shown in Figure 7, the top surface of the support frame 201 is horizontally fixedly connected with a mounting platform 202, and a guide rail 208 is arranged on the mounting platform 202 perpendicular to the first direction. A guide groove 212 that slides with the guide rail 208 is arranged on the bottom surface of the translation platform 203, and a translation cylinder 207 for respectively pushing the two translation platforms 203 to move is also arranged on the mounting platform 202. The guide rail 208 and the guide groove 212 cooperate with each other, and can guide and support the movement of the translation platform 203, improve the stability of the translation platform 203, and the translation platform 203 is pushed and moved by the translation cylinder 207, and then the support roller 204 is driven to move through the translation platform 203.

[0032] A further improvement is, Figure 2 , 6 As shown in FIG. 7 , the axis of the support roller 204 is perpendicular to the first direction, the support roller 204 is rotatably connected to the translation platform 203, and the translation platform 203 is provided with a flip cylinder 209 for driving the support roller 204 to rotate. The flip cylinder 209 can push the support roller 204 to rotate around the hinge point with the translation platform 203, thereby achieving the angle adjustment of the support roller 204, and then the angle adjustment between the support rollers 204 located on the two translation platforms 203 can be adjusted, so that the intersection point of the two support rollers 204 has a larger height adjustment range, further improving the practicality of the rolling equipment.

[0033] A further improvement is, Figure 2-4As shown, a blanking trough 211 is provided in the middle of the mounting platform 202 along the first direction, and the blanking trough 211 is located directly below the discharge port of the rolling channel 101. Two translation platforms 203 are respectively arranged on both sides of the blanking trough 211, and a conveying roller 205 is arranged directly below the blanking trough 211. In order to facilitate the discharge of materials and save the time for the staff to move the stainless steel pipe off the support roller 204; when the stainless steel pipe is rolled and comes out of the rolling channel 101, the two translation platforms 203 move away from each other until the support rollers 204 on the two translation platforms 203 are completely separated by a certain distance, and the stainless steel pipe falls from between the two translation platforms 203 to the inside of the blanking trough 211, and finally falls onto the conveying roller 205. One end of the conveying roller 205 can be connected to a bracket or a trolley for collecting stainless steel pipes, and the conveying roller 205 can transport the stainless steel pipe to the bracket or the trolley for placement, thereby realizing the automatic unloading of the stainless steel pipe and improving the working efficiency of the rolling equipment.

[0034] A further improvement is, Figure 3-5 As shown, a slow-descent assembly is provided on the support frame 201, and the slow-descent assembly is located between the material drop chute 211 and the conveyor roller 205; the slow-descent assembly includes a support belt 213, one end of the support belt 213 is connected to one side edge of the material drop chute 211, and a winding shaft 210 is provided on the other side edge of the material drop chute 211, and the other end of the support belt 213 is wound on the outer periphery of the winding shaft 210, and the support frame 201 is provided with a driving member 206 for driving the winding shaft 210 to rotate. The driving member 206 is a motor with a reduction gearbox, and the motor is provided with a brake device. When the motor stops, the brake device can prevent the motor shaft from rotating. The driving member 206 drives the winding shaft 210 to rotate forward and reversely, thereby adjusting the length of the support belt 213. Before the stainless steel pipe falls into the blanking chute 211, the support belt 213 is shortened, and the height of the middle part of the support belt 213 is increased, so that when the stainless steel pipe falls onto the support belt 213, the support belt 213 catches the stainless steel pipe, which can reduce the length of the stainless steel pipe. The impact force can reduce the probability of damage to the stainless steel pipe when it falls; then the support belt 213 is released and the length increases, and the support belt 213 drives the stainless steel pipe to slowly fall until the bottom end of the support belt 213 falls between the rollers of the conveyor roller 205, and the stainless steel pipe contacts the conveyor roller 205, and then the stainless steel pipe is transported away by the conveyor roller. When the stainless steel pipe is separated from the support belt 213, the support belt 213 can be shortened and reset; the support belt 213 can reduce the probability of damage to the stainless steel pipe when it falls.

[0035] A further improvement is that a flexible protective layer is provided on the surface of the support belt 213. The protective layer can be a sponge pad or a cloth pad. The provision of the protective layer can firstly protect the support belt 213, reduce its wear and tear and extend its service life, and also play a buffering role, reduce the wear of the stainless steel pipe, and improve the quality of the stainless steel pipe.
