DETAILED DESCRIPTION

[0032] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0033] In order to reduce the surface defects of the seamless steel pipe to be drawn and improve the drawing efficiency and quality, in one embodiment, Figure 1-3 As shown, a cold drawing machine for automatic processing of stainless steel seamless steel pipes comprises a cold drawing machine body 100; a workbench 300, which is arranged at the feeding end of the drawing machine body 100; a pushing mechanism, which is arranged on the workbench 300 and located at the feeding end of the cold drawing machine body 100, and is used to drive the seamless steel pipe into the cold drawing machine body 100; a feeding mechanism 400, which is arranged on the workbench 300 and located at one side of the pushing mechanism, and is used to feed the seamless steel pipe onto the pushing mechanism; a cleaning and lubricating mechanism 600, which is arranged between the feeding end of the cold drawing machine body 100 and the unloading end of the pushing mechanism, and the cleaning and lubricating mechanism 600 comprises a grinding component, a blowing component and a and a lubrication component, the grinding component, the blowing component and the lubrication component are externally rotatably sleeved with a fixed barrel 601, the blowing component is provided with a plurality of groups of radially movable air outlet parts, the lubrication component is provided with a plurality of groups of radially movable oil outlet parts, a movable part 610 is provided between each group of the air outlet parts and the oil outlet parts, when the steel pipe is inserted between the plurality of movable parts 610 after being polished by the grinding component, when the steel pipe collides with the movable part 610, the movable part 610 moves away from the seamless steel pipe, realizing the outflow of gas and lubricating oil, cleaning the surface of the steel pipe of debris and applying lubricating oil to the surface of the steel pipe, reducing the surface quality problems of the seamless steel pipe, and improving the quality and drawing efficiency of the drawn steel pipe.

[0034] In order to improve the grinding, cleaning and lubrication effect, in one embodiment, Figure 2 , 3 As shown, the cleaning and lubrication mechanism 600 also includes a driving member, which includes a driven wheel 604 fixedly sleeved on the surface of the grinding component, and the inner wall of the fixed barrel 601 is fixedly connected to a motor 602 through a bracket, and a driving wheel 603 meshing with the driven wheel 604 is fixedly connected to the output shaft of the motor 602. The motor 602 drives the driving wheel to rotate, and the driving wheel 603 drives the driven wheel 604 to rotate through meshing, and the driven wheel 604 drives the grinding component to rotate, so that the grinding component can rotate around the seamless steel pipe, thereby improving the grinding effect of the surface of the seamless steel pipe and effectively avoiding the presence of large unpolished areas on the seamless steel pipe. Since the grinding component is fixedly connected to the blowing component and the lubricating component in sequence, the grinding component can drive the blowing component and the lubricating component to rotate around the seamless steel pipe, thereby improving the cleaning effect of debris on the surface of the steel pipe and the application effect of the lubricating oil, and avoiding leakage cleaning and uneven application of the lubricating oil.

[0035] In order to achieve the seamless steel pipe surface rust, unevenness treatment, in one embodiment, such as Figure 3As shown, the grinding assembly includes a fixed ring 606, multiple groups of electric push rods installed on the inner wall of the fixed ring 606, and a grinding sheet 607 fixedly installed on the telescopic end of the electric push rod. The electric push rod drives the grinding sheet 607 to fit the surface of the seamless steel pipe to grind the surface of the seamless steel pipe, wherein the surface of the fixed ring 606 is fixedly sleeved with the driven wheel.

[0036] When the seamless steel pipe is inserted, multiple groups of electric push rods are started. The electric push rods drive the grinding disc 607 to fit the surface of the seamless steel pipe. Under the action of the driving member, the grinding disc 607 rotates around the seamless steel pipe and grinds its surface to remove rust and unevenness on the surface of the seamless steel pipe, improve the surface flatness of the steel pipe, and prevent rust residue on the seamless steel pipe from entering the cold drawing machine body 100 and causing scratches on the surface of the seamless steel pipe during the drawing process.

[0037] In order to facilitate the insertion of the seamless steel pipe into the area surrounded by the multiple groups of moving parts 610, in one embodiment, as shown in FIG. Figure 3 As shown, the movable part 610 includes an inclined section and a straight section integrally formed with the inclined section. The diameter of the insertion area surrounded by multiple groups of inclined sections gradually decreases in the direction away from the grinding component. The air outlet end of the air outlet part is arranged on the inclined section of the movable part 610, and the oil outlet part is arranged on the straight section of the movable part.

[0038] The inclined sections of multiple groups of moving parts 610 are surrounded by a conical area. On the one hand, it can provide a clear guide for the insertion of the seamless steel pipe, ensuring that the steel pipe can be accurately inserted into the area surrounded by the straight sections of the moving parts 610 along the predetermined direction, so that the seamless steel pipe can push the multiple groups of moving parts to move away from each other during the insertion process. On the other hand, it leaves blowing space and debris collection space for the blowing assembly to achieve a better effect of cleaning the debris on the surface of the steel pipe. The straight sections of multiple groups of moving parts 610 are surrounded by a cylindrical area, which can be fitted with the surface of the seamless steel pipe, making it easier to apply lubricating oil to the surface of the seamless steel pipe.

[0039] In order to achieve the chip cleaning of the inserted seamless steel pipe surface, in one embodiment, referring to Figure 3-6 The blowing assembly further includes a second fixing ring 608 coaxially arranged with the first fixing ring 606, and an expansion cavity 6081 coaxially arranged with the second fixing ring 608 is provided in the second fixing ring 608, and a plurality of moving cavities 6082 communicating with the expansion cavity 6081 and providing the air outlet member with upward and downward movement are provided on the second fixing ring 608;

[0040] The gas outlet member includes a moving rod 6084 movably plugged into the moving cavity 6082, one end of the moving rod 6084 is fixedly plugged into the inclined section of the moving member 610 and the end is connected to the external environment, a spring 2 is arranged on the surface of the moving rod 6084 and located between the fixed ring 2 608 and the moving member 610, and a plurality of through holes 6083 are arranged on the surface of the moving rod 6084 and located at one end away from the moving member 610, when the through holes 6083 of the moving rod 6084 are located inside the expansion cavity 6081, the gas inside the expansion cavity 6081 enters the interior of the moving rod 6084 through the through holes 6083 and flows out;

[0041] The lubrication assembly further includes a third fixing ring 609 coaxially arranged with the second fixing ring 608 and a storage cavity provided in the third fixing ring 609;

[0042] The oil outlet part includes a second moving rod 6092 movably plugged into the storage cavity, one end of the second moving rod 6092 is fixedly plugged into the straight section of the moving part 610, a spring 3 is arranged on the surface of the second moving rod 6092 and located between the third fixing ring 609 and the moving part 610, a temporary storage cavity connected to the second moving rod 6092 is provided inside the moving part 610 and located at the straight section, a plurality of groups of lubricating balls 6101 are rotatably connected inside the moving part 610 and located at the straight section, and the lubricating balls 6101 are connected to the temporary storage cavity;

[0043] An annular airbag 6091 is provided in the storage chamber in the fixed ring 3 609 , and the annular airbag 6091 divides the storage chamber into a lubricating oil chamber and a gas chamber from the inside to the outside, and a connecting pipe is provided between the gas chamber and the movable chamber 6082 .

[0044] like Figure 6 As shown, when the seamless steel pipe has not entered the cleaning and lubricating mechanism, at this time, since there is no seamless steel pipe to apply force to the moving part 610, under the action of the second spring and the third spring, the through hole 1 6083 of the moving rod 1 6084 is located in the moving cavity 6082, and the top of the moving rod 1 6084 is located below the connecting pipe. At this time, the expansion cavity 6081 is connected with the gas cavity in the storage cavity in the fixed ring 3 609 through the connecting pipe, and the gas enters the expansion cavity 6081 from the gas outlet pipe 6051, and enters the gas cavity from the expansion cavity 6081 through the connecting pipe to squeeze the annular airbag 6091, while the through hole 2 6093 opened on the moving rod 2 6092 is not connected with the lubricating oil cavity, so the lubricating oil cannot flow out, which effectively avoids the waste caused by the lubricating oil flowing out when the seamless steel pipe is not inserted;

[0045] like Figure 5As shown, when the seamless steel pipe enters the cleaning and lubricating mechanism, the steel pipe is inserted and conflicts with the moving member 610, and the moving member 610 moves in the direction away from the seamless steel pipe. At this time, the moving rod 1 6084 and the moving rod 2 6092 both move in the direction away from the seamless steel pipe, and the through hole 1 6083 on the moving rod 1 6084 enters into the expansion cavity 6081 and the moving rod 1 6084 seals the connecting pipe. At this time, the gas enters into the moving rod 1 6084 from the expansion cavity 6081 through the through hole 1 6083, and is blown from the end of the moving rod 1 6084 to the surface of the seamless steel pipe, so that the debris on the surface of the seamless steel pipe is cleaned;

[0046] The through hole 6093 provided on the movable rod 6092 is connected to the lubricating oil chamber. Under the squeezing action of the annular airbag 6091, the pressurized lubricating oil is squeezed into the movable rod 6092 through the through hole 6093, and then transported to the temporary storage chamber by the movable rod 6092, so that the lubricating oil is sprayed out from the gap between the lubricating ball 6101 and the movable part 610, thereby achieving the lubrication of the seamless steel pipe, reducing the friction during the drawing of the steel pipe, making the seamless steel pipe smoother during the cold drawing process, and avoiding wear.

[0047] The above can achieve one-time cleaning and lubrication of seamless steel pipes. In order to ensure uninterrupted operation of the equipment, in one embodiment, Figure 4-8 As shown, the cleaning and lubricating mechanism also includes a plurality of air supply components 605, and the air supply components 605 include a cylinder 6056 fixedly arranged on the fixed ring 3 609, and a movable rod 6052 is movably inserted at one end of the cylinder 6056 away from the fixed ring 3 609, and a resistance ball is fixedly connected at one end of the movable rod 6052 away from the cylinder 6056, and the resistance ball abuts against the inner wall of the fixed barrel 601, and a plurality of arc-shaped protrusions 6011 integrally formed and fixedly connected on the fixed barrel 601 for the movable rod 6052 to reciprocate along the extension direction of the cylinder 6056, The movable rod 6052 is located at one end inside the cylinder 6056 and is fixedly connected to the piston 6054. A spring 6055 is wound around the surface of the movable rod 6052 and is located between the piston 6054 and the inner wall of the cylinder 6056. An air outlet pipe 6051 is provided on the side wall of one side of the cylinder 6056 and is located at the bottom of the piston 6054. The air outlet end of the air outlet pipe 6051 is connected to the expansion chamber 6081. The other side wall of the cylinder 6056 is connected to the air inlet pipe 6053. Both the air inlet pipe 6053 and the air outlet pipe 6051 are provided with a one-way valve.

[0048] When the equipment is running, the driving part drives the fixing ring 1, the fixing ring 2 and the fixing ring 3 to rotate, and the abutment ball at the end of the movable rod 6052 away from the cylinder 6056 continuously collides with the arc-shaped protrusion 6011. The movable rod 6052 and the piston 6054 reciprocate up and down on the inner wall of the cylinder 6056 under the action of the spring 1 6055. When the piston 6054 moves away from the outlet pipe 6051, the inside of the cylinder 6056 is in a negative pressure state. At this time, the air inlet pipe 6053 The one-way valve on the air inlet pipe 6053 is opened, and external air enters the cylinder 6056 through the air inlet pipe 6053. When the piston 6054 moves toward the air outlet pipe 6051, the one-way valve on the air inlet pipe 6053 is closed. At this time, the air is compressed and enters the air outlet pipe 6051, and is transported to the expansion chamber 6081 by the air outlet pipe 6051. The air supply component can repeatedly inhale and blow air during the rotation process, thereby realizing uninterrupted cleaning and lubrication of the seamless steel pipe and improving work efficiency.

[0049] In order to reduce manual work and achieve automation, in one embodiment, Figure 1 , Fig. 9 and Fig.10 As shown, the feeding mechanism 400 includes a feeding hopper 401 arranged on the workbench 300, and a material distribution core 402 is rotatably arranged at the feeding port of the feeding hopper 401 and along the extension direction of the feeding hopper 401, and a multi-component material trough 403 compatible with the seamless steel pipe is opened on the material distribution core 402, and a motor is fixedly installed at the power end of the material distribution core 402.

[0050] The pushing mechanism includes a plurality of slide plates 404 and a hydraulic rod 500 disposed below the upper hopper 401. A groove is provided at one end of the slide plate 404 away from the upper hopper 401. The groove is aligned with the center line of the hydraulic rod 500. A guide block 200 is provided at the feeding end of the cleaning and lubricating mechanism 600 and located on the workbench 300.

[0051] After the equipment is started, the motor in the feeding mechanism drives the dividing core 402 to rotate. The seamless steel pipe in the upper hopper will enter the dividing groove opened on the dividing core 402 in sequence as the dividing core 402 rotates. After turning to the bottom of the upper hopper 401, it will roll down from the notch opened under the upper hopper to the slide plate 404 in sequence, and then enter the groove opened on the slide plate 404, pushing the mechanism to work, and the hydraulic rod 500 pushes the seamless steel pipe to enter the guide block 200 in sequence, cleaning the lubrication mechanism 600 and the cold drawing body 100.

[0052] In one embodiment, a guide cavity 201 is opened in the guide block 200, and the guide cavity 201 includes an arc section close to the cleaning and lubricating mechanism 600 and a conical section away from the cleaning and lubricating mechanism 600. The pushing mechanism pushes the seamless steel pipe into the conical section and the straight section in sequence, which can effectively correct the deviation of the steel pipe position when pushing the seamless steel pipe.

[0053] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit them.
