Description

Technical Field

[0001] The present invention relates to the technical field of cold rolling of stainless steel pipes, and specifically to a cold rolling processing device and method for stainless steel pipes. Background Art

[0002] Due to its corrosion resistance, high temperature resistance, and high pressure resistance, stainless steel pipes are widely popular in fields such as petrochemical industry, offshore engineering, and aerospace. With high bending and torsional strength and light weight, they are also commonly used in the manufacture of mechanical parts, engineering structures, furniture, and kitchenware. Currently, the cold rolling of stainless steel pipes is mainly completed by a cold rolling mill, where the tube blank needs to roll forward and reduce the diameter and fix the diameter on the mandrel to achieve rolling. Before rolling, cold rolling oil needs to be applied to the inner and outer walls of the tube blank for lubrication to avoid excessive scratches and thus improve the quality of the finished product.

[0003] Due to the friction between the cold rolling mill and the stainless steel pipe, a large amount of heat will be generated between the cold rolling mill and the steel pipe. Therefore, it is also necessary to spray coolant on them. In addition, a large amount of lubricating oil is involved in the forming of stainless steel pipes. When the staff is loading and unloading, the lubricating oil will adhere to the staff's hands. So when the staff is performing the next task such as checking the forming of the stainless steel pipe, they need to use hot water to wash the lubricating oil on their hands. When the sprayed coolant cools itself, it will dissipate a lot of heat. If this heat is not utilized, it will cause a certain degree of energy waste. In addition, the coolant generally flows back through a liquid pump. After the coolant works, there are certain impurities in it, which can easily affect the normal operation of the liquid pump during long-term use, and thus may affect the operation of the cold rolling mill. Summary of the Invention

[0004] The purpose of the present invention is to provide a cold rolling processing device for stainless steel pipes. When cold rolling the stainless steel pipe, under the drive of the driving mechanism body, the liquid supply mechanism can be made to work.

By means of physical structure linkage, the problem of the liquid pump being damaged due to impurities or high temperature in the coolant is avoided.

[0005] In addition, when the liquid return mechanism is working, the liquid squeezing mechanism can also be made to drive the circulation mechanism to work. Then, through the circulation mechanism, the heat of the coolant can be taken out to achieve the purpose of quickly dissipating the heat of the coolant. And under the action of the diversion mechanism, hot water can directly flow out for the staff to use.

[0018] A method for a cold rolling processing device of a stainless steel pipe, the method comprising the following steps: [[ID=1-4]]

[0019] S1. When cold rolling the stainless steel pipe, the staff can feed the stainless steel pipe through the inlet pipe and make it pass through the cold rolling machine body into the working shell. Then, under the action of the cold rolling workpiece body and the driving mechanism body, the stainless steel pipe can be cold rolled. When cold rolling the stainless steel pipe, the driving mechanism body can be provided with coolant through the liquid tank, thereby reducing the heat generated by friction during the cold rolling of the cold rolling workpiece body and the stainless steel pipe.

[0020] S2. After the coolant acts on the surface of the stainless steel pipe, the coolant can enter the liquid collection cover through the filter holes. In addition, when the driving mechanism body drives the cold-rolled workpiece body to move back and forth, under the action of the first connecting plate and the second connecting plate, the airbag can be deformed, and then the pressure in the airbag cavity changes. Driven by the airbag, the piston plate moves back and forth in the sealing pipe cavity, so that the pressure at the connection part of the piston plate cavity, the first connecting liquid pipe and the second connecting liquid pipe changes. Then, under the action of the pressure, the first connecting liquid pipe extracts the coolant in the liquid collection cover. With the assistance of the one-way valve, the coolant first enters the sealing pipe, and then under the push of the piston plate, the coolant enters the second connecting liquid pipe and the liquid tank to complete the recycling work of the coolant.

[0021] S3. In addition, when there is coolant accumulation in the liquid collection cover, the heat of the coolant can be transferred to the heat exchange pipe, and under the action of the water flow in the heat exchange pipe cavity, the heat is transported outward. Since there is coolant flowing in the first connecting liquid pipe, the windmill is rotated under the impact of the coolant, so that the first transmission rod drives the second transmission rod and the third transmission rod to rotate. The turntable fixed on one side of the surface of the third transmission rod can make the fitting ball rotate. When the fitting ball fits with the third connecting water pipe, the water in the inner cavity of the third connecting water pipe can be squeezed to provide pressure for the water flow, so that the water in the inner cavity of the third connecting water pipe flows. When the water in the inner cavity of the third connecting water pipe has pressure, the water in the heat exchange pipe, the first connecting water pipe, the second connecting water pipe, the third connecting water pipe and the fourth connecting water pipe can circulate. When the water flows out of the liquid collection cover, the purpose of heat dissipation can be achieved.

[0022] S4. Since a large amount of lubricating oil is involved in the cooling of the stainless steel pipe, when the staff is loading and unloading, the lubricating oil will adhere to the hands of the staff. Therefore, when the staff is performing the next task, such as checking the forming situation of the stainless steel pipe, it is necessary to clean the lubricating oil on the hands. At this time, the staff can use the cover plate. When the cover plate is turned over, the connecting rods fixed on both sides of the surface of the cover plate can rotate. Then, under the action of the transmission parts, the driving disc rotates. The first hinge on the surface of the driving disc can make the second hinge work, so that the sealing block moves away from the sealing shell. After the sealing block leaves the sealing shell, water can flow in the hand-washing pipe, and then hot water can flow out of the hand-washing pipe. The staff can use the hot water to clean the lubricating oil on the hands. The temperature of the hot water can be controlled by the length of the first connecting water pipe.

[0023] S5. When the sealing blocks on both sides leave the sealing shell, the water in the water supply tank can flow into the water supply pipe under the action of gravity and hydraulic balance, and enter the heat exchange tube through the drive of the liquid-expelling mechanism, so as to achieve the purpose of replenishing the water in the heat exchange tube. After the staff finishes cleaning the oil stains on their hands, closing the cover can make the circulation mechanism work normally.

[0024] Compared with the prior art, the present invention has the following beneficial effects:

[0025] When cold rolling a stainless steel pipe, the present invention can enable the liquid supply mechanism to work under the drive of the driving mechanism body, and then under the action of the liquid supply mechanism, the coolant in the liquid return mechanism can flow back, thereby achieving the purpose of reuse. Through the physical structure linkage, the problem of the coolant passing through the liquid pump impurities or high temperature to damage the liquid pump is avoided.

[0026] In addition, when the liquid return mechanism is working, the liquid chasing mechanism can also drive the circulation mechanism to work, and then the heat of the coolant can be taken out through the circulation mechanism, so as to achieve the purpose of quickly dissipating the heat of the coolant. Under the action of the diversion mechanism, hot water can flow out directly for use by the staff, and under the setting of the circulation mechanism's own structure, the purpose of automatic liquid replenishment can be achieved.

[0044] When the present invention cold-rolls a stainless steel pipe, it can drive the liquid supply mechanism 9 to work under the drive of the driving mechanism body 5. Then, under the action of the liquid supply mechanism 9, the coolant in the liquid return mechanism 8 can flow back, achieving the purpose of recycling. By means of physical structure linkage, the problem of the coolant damaging the liquid pump due to impurities or high temperature in the liquid pump is avoided.

[0045] In addition, when the liquid return mechanism 8 works, it can also drive the circulation mechanism 12 to work by the liquid driving mechanism 13.

[0048] The liquid supply mechanism 9 includes a first connecting plate 91 fixed to the surface of the cold-rolled workpiece body 4. A balloon 92 is fixed to the surface of the first connecting plate 91. The other end of the balloon 92 is fixed to a second connecting plate 93. The second connecting plate 93 is fixed to the inner cavity of the working housing 3. The other end of the balloon 92 is communicated with a sealing pipe 94. A piston plate 95 is slidably arranged in the inner cavity of the sealing pipe 94. The sealing pipe 94 is connected to the first connecting liquid pipe 82. In this embodiment, through the setting of the first connecting plate 91, the balloon 92, the second connecting plate 93, the sealing pipe 94 and the piston plate 95, when the cold-rolled workpiece body 4 moves back and forth, the first connecting plate 91 fixed to the surface of the cold-rolled workpiece body 4 can compress and stretch the balloon 92, and then the air pressure in the sealing pipe 94 communicated with the balloon 92 can change, so that the piston plate 95 moves reciprocally. Thus, under the action of the piston plate 95, the liquid supply mechanism 9 is coordinated to convey the coolant.

[0049] Limit rods 10 are slidably arranged on both sides of the surface of the piston plate 95. Both sides of the limit rods 10 are fixed to the inner cavity of the sealing pipe 94.

Then, under the action of the water flow in the inner cavity of the heat exchange tube 121, the heat is transferred outward. Thus, when the water flows through the heat exchange tube 121, the first connecting water pipe 122, the second connecting water pipe 123, the third connecting water pipe 124 and the fourth connecting water pipe 125, the heat can be diffused outward. In addition, under the action of the handwashing pipe 128, the water supply pipe 126 and the water supply tank 127, the effect of supplying hot water to the staff and replenishing water to the heat exchange tube 121 can be achieved.

The limiting block 137 is disposed at the fitting part of the fitting ball 136 and the third connecting water pipe 124, and the other end of the limiting block 137 is fixed on the surface of the working housing 3. In this embodiment, through the arrangement of the windmill 131, the first transmission rod 132, the second transmission rod 133, the third transmission rod 134, the turntable 135 and the fitting balls 136, when there is coolant flowing in the inner cavity of the first connecting liquid pipe 82, under the impact of the coolant, the windmill 131 can drive the first transmission rod 132 to rotate. Then, under the transmission of the second transmission rod 133, the third transmission rod 134 and the turntable 135 rotate. And a plurality of fitting balls 136 fixed on the surface of the turntable 135 can fit with the first connecting liquid pipe 82, so that the liquid in the first connecting liquid pipe 82 flows.

[0052] The road-changing mechanism 16 includes connecting rods 161 fixed on both sides of the rotating shaft of the cover plate 15.

Then, under the action of the connecting rod 161, the transmission member 162 drives the driving disk 163 to rotate. The first hinge member 164 hinged on the surface of the driving disk 163 can make the second hinge member 165 and the sealing block 166 move, so that the sealing block 166 moves away from or enters the sealing shell 167.

[0053] The sealing block 166 slides in the inner cavity of the sealing shell 167, and the sealing shell 167 provides a limit to the sliding distance of the sealing block 166. In this embodiment, through this setting, the sealing shell 167 restricts the movement of the sealing block 166 and provides support for the work of the sealing block 166 and the second hinge member 165, improving the stability of the sealing block 166 during work.

[0054] A method for a cold rolling processing device of a stainless steel pipe, the method comprising the following steps:

[0055] S1. When cold rolling the stainless steel pipe, the staff can feed the stainless steel pipe through the inlet pipe 2 and make it pass through the cold rolling machine body 1 into the working shell 3. Then, under the action of the cold rolling workpiece body 4 and the driving mechanism body 5, the stainless steel pipe can be cold rolled. When the stainless steel pipe is cold rolled, the liquid tank 6 can provide coolant for the driving mechanism body 5, thereby reducing the heat generated by friction during the cold rolling of the cold rolling workpiece body 4 and the stainless steel pipe. The working principles of the cold rolling machine body 1, the inlet pipe 2, the working shell 3, the cold rolling workpiece body 4, the driving mechanism body 5 and the liquid tank 6 are prior arts and will not be elaborated here.

[0056] S2. After the coolant acts on the surface of the stainless steel pipe, the coolant can enter the liquid collecting cover 81 through the filter holes 7. In addition, when the driving mechanism body 5 drives the cold-rolled workpiece body 4 to move back and forth, under the action of the first connecting plate 91 and the second connecting plate 93, the airbag 92 deforms, and then the pressure inside the airbag 92 changes. Driven by the airbag 92, the piston plate 95 moves back and forth inside the sealing pipe 94, so that the pressure at the connection part between the inner cavity of the piston plate 95, the first connecting liquid pipe 82 and the second connecting liquid pipe 83 changes. Then, under the action of the pressure, the first connecting liquid pipe 82 extracts the coolant in the liquid collecting cover 81, and with the assistance of the one-way valve 84, the coolant first enters the sealing pipe 94, and then is pushed by the piston plate 95 into the second connecting liquid pipe 83 and the liquid tank 6 to complete the recycling of the coolant.

[0057] S3. In addition, when there is coolant accumulation in the liquid collecting cover 81, the heat of the coolant can be transferred to the heat exchange pipe 121, and under the action of the water flow inside the heat exchange pipe 121, the heat is transported outwards. Since there is coolant flowing in the first connecting liquid pipe 82, under the impact of the coolant, the windmill 131 rotates, so that the first transmission rod 132 drives the second transmission rod 133 and the third transmission rod 134 to rotate. The turntable 135 fixed on one side of the surface of the third transmission rod 134 can make the fitting ball 136 rotate. When the fitting ball 136 is in contact with the third connecting water pipe 124, the water inside the third connecting water pipe 124 can be squeezed to provide pressure for the water flow, so that the water inside the third connecting water pipe 124 flows. When the water inside the third connecting water pipe 124 has pressure, the water in the heat exchange pipe 121, the first connecting water pipe 122, the second connecting water pipe 123, the third connecting water pipe 124 and the fourth connecting water pipe 125 can circulate. When the water flows out of the liquid collecting cover 81, the purpose of heat dissipation can be achieved.

[0058] S4. Since a large amount of lubricating oil is involved in the cooling of the stainless steel pipe, when the staff performs loading and unloading, the lubricating oil will adhere to the hands of the staff. Therefore, when the staff performs the next task, such as checking the forming condition of the stainless steel pipe, it is necessary to clean the lubricating oil on the hands. At this time, the staff can use the cover plate 15. When the cover plate 15 is turned over, the connecting rods 161 fixed on both sides of the surface of the cover plate 15 can rotate. Then, under the action of the transmission member 162, the driving disc 163 is driven to rotate. The first hinge member 164 rotating on the surface of the driving disc 163 can make the second hinge member 165 work, so that the sealing block 166 moves away from the sealing shell 167. After the sealing block 166 leaves the sealing shell 167, water can flow in the handwashing pipe 128. Then, hot water can flow out from the handwashing pipe 128, and the staff can use the hot water to clean the lubricating oil on the hands. The temperature of the hot water can be controlled by the length of the first connecting water pipe 122.

[0059] S5. When both sealing blocks 166 on both sides leave the sealing shell 167, the water in the water supply tank 127 can flow into the water supply pipe 126 under the action of gravity and hydraulic balance, and enter the heat exchange pipe 121 driven by the liquid expelling mechanism 13, so as to achieve the purpose of supplementing the water in the heat exchange pipe 121. After the staff finishes cleaning the oil stains on the hands, closing the cover plate 15 can make the circulation mechanism 12 work normally.

10. A method for a cold rolling processing device of a stainless steel pipe, characterized in that: The method includes the following steps: S1. When cold rolling a stainless steel pipe, the staff can feed the stainless steel pipe through the inlet pipe orifice (2), and make it pass through the cold rolling machine body (1) into the working housing (3). Then, under the action of the cold rolling workpiece body (4) and the driving mechanism body (5), the stainless steel pipe can be cold rolled. When the stainless steel pipe is cold rolled, the liquid tank (6) can provide coolant for the driving mechanism body (5), thereby reducing the heat generated by friction during the cold rolling of the cold rolling workpiece body (4) and the stainless steel pipe. S2. After the coolant acts on the surface of the stainless steel pipe, the coolant can enter the liquid collecting cover (81) through the filter holes (7). In addition, when the driving mechanism body (5) drives the cold rolling workpiece body (4) to move back and forth, under the action of the first connecting plate (91) and the second connecting plate (93), the airbag (92) can be deformed, thereby causing the pressure inside the airbag (92) to change. Driven by the airbag (92), the piston plate (95) moves back and forth inside the sealed pipe (94), so that the pressure at the connection part between the inner cavity of the piston plate (95), the first connecting liquid pipe (82), and the second connecting liquid pipe (83) changes. Then, under the action of the pressure, the first connecting liquid pipe (82) extracts the coolant in the liquid collecting cover (81), and with the assistance of the one-way valve (84), the coolant first enters the sealed pipe (94), and then is pushed by the piston plate (95) into the second connecting liquid pipe (83) and the liquid tank (6) to complete the recycling work of the coolant. S3. In addition, when there is coolant accumulation in the liquid collecting cover (81), the heat of the coolant can be transferred to the heat exchange pipe (121), and under the action of the water flow inside the heat exchange pipe (121), the heat is transported outward. Since there is coolant flowing in the first connecting liquid pipe (82), the windmill (131) is rotated by the impact of the coolant, so that the first transmission rod (132) drives the second transmission rod (133) and the third transmission rod (134) to rotate. The turntable (135) fixed on one side of the surface of the third transmission rod (134) can make the fitting ball (136) rotate. When the fitting ball (136) fits with the third connecting water pipe (124), the water inside the third connecting water pipe (124) can be squeezed to provide pressure for the water flow, thereby making the water inside the third connecting water pipe (124) flow. When the water inside the third connecting water pipe (124) has pressure, the water in the heat exchange pipe (121), the first connecting water pipe (122), the second connecting water pipe (123), the third connecting water pipe (124), and the fourth connecting water pipe (125) can circulate. When the water flows out of the liquid collecting cover (81), the purpose of heat dissipation can be achieved. S4. Since a large amount of lubricating oil is involved in the cooling of the stainless steel pipe, when the staff is loading and unloading, the lubricating oil will adhere to the hands of the staff. Therefore, when the staff is performing the next task, such as checking the forming condition of the stainless steel pipe, it is necessary to clean the lubricating oil on the hands. At this time, the staff can use the cover plate (15). When the cover plate (15) is flipped, the connecting rods (161) fixed on both sides of the surface of the cover plate (15) can rotate. Then, under the action of the transmission member (162), the driving disk (163) is driven to rotate. The first hinge member (164) rotating on the surface of the driving disk (163) can cause the second hinge member (165) to work, and then the sealing block (166) moves away from the sealing shell (167). After the sealing block (166) leaves the sealing shell (167), water can flow in the handwashing pipe (128). Then, hot water can flow out from the handwashing pipe (128), and the staff can use the hot water to clean the lubricating oil on the hands. The temperature of the hot water can be controlled by the length of the first connecting water pipe (122). S5. When both sealing blocks (166) on both sides leave the sealing shell (167), the water in the water supply tank (127) can flow into the water supply pipe (126) under the action of gravity and hydraulic balance, and is driven by the liquid expelling mechanism (13) to enter the heat exchange pipe (121) to achieve the purpose of replenishing the water in the heat exchange pipe (121). After the staff finishes cleaning the oil stains on the hands, closing the cover plate (15) can make the circulation mechanism (12) work normally.
