A transfer device for preventing displacement during stainless steel pipe processing

Abstract

The invention discloses a transfer device for preventing displacement during stainless steel pipeline processing, comprising a limit roller, a limit plate, a fixed plate and a welding table, wherein the limit plate is symmetrically mounted on the limit roller and movably arranged. When the pipeline transfers slowly, the water flow rate of the water pipe is increased by sliding and shrinking the closing plate inward, and the pipeline temperature is reduced by heat exchange between the water pipe and the heat guide sleeve to prevent the pipeline from being deformed at high temperature. When the pipeline transfers quickly or at a normal rate, similarly, the water flow rate is reduced to prevent the heating effect on the pipeline from being reduced. When the transfer is slow, the heated cleaning liquid is diverted to the water collecting tank in the fixed table, so that the cleaning nozzle sprays the cleaning liquid to clean the steel parts at high temperature. When the transfer is fast or at a normal rate, water vapor is sprayed from the cleaning nozzle, thereby reducing the water spraying amount while maintaining the cleaning effect. The steel is heated and cleaned by the heated cleaning liquid, which is convenient for the steel to be deformed during the transfer process.

Description

Technical Field

[0001] The invention relates to the technical field of steel pipe processing and transfer equipment, in particular to a transfer device for preventing displacement during stainless steel pipe processing. Background Art

[0002] In the process of processing stainless steel into pipes, it is usually necessary to ensure the accuracy and stability of the position of the pipes during the processing. The displacement transfer device can not only help the pipes maintain the correct position during processing to avoid deviations or defects in processing due to displacement, but also transport and transfer the formed pipes to facilitate subsequent processing operations.

[0003] If steel with a larger diameter and width is not cleaned sufficiently before forming, it is easy for dirt such as oil stains and oxides to remain on the surface of the steel, which will affect the subsequent welding operation and reduce the welding quality. At the same time, in order to improve the rigidity of the pipeline after processing and forming, the pipeline is often heated and then cooled to improve the rigidity. When the transfer speed is slow, the pipeline is heated in the heating zone for a long time, which can easily cause the pipeline to deform at high temperature, thereby affecting the quality of the pipeline.

[0017] The present invention provides a transfer device for preventing displacement of stainless steel pipes during processing, which has the following technical points and beneficial effects:

[0018] 1. The present invention designs devices such as a closing plate, a heat-conducting sleeve and a high-frequency heating tube. When the pipeline transfers slowly, the closing plate is slid inward and contracted to increase the water flow rate of the water pipe. The pipeline temperature is reduced through heat exchange between the water in the water pipe and the heat-conducting sleeve to prevent the pipeline from being deformed due to high temperature. When the pipeline transfers quickly or at a normal rate, the water flow rate is reduced to prevent the heating effect on the pipeline from being reduced. When the transfer is slow, the heated cleaning liquid is diverted to the water collecting tank in the fixed table, so that the cleaning nozzle sprays the cleaning liquid to clean the steel parts at high temperature. When the transfer is fast or at a normal rate, water vapor is sprayed from the cleaning nozzle, thereby reducing the water spray volume while maintaining the cleaning effect. The steel is heated and cleaned by the heated cleaning liquid, which facilitates the deformation of the steel during the transfer process and improves the positioning effect of the steel during transfer.

[0019] 2. The present invention designs devices such as a water pipe, a lifting arm and a support rod, and controls the lifting and lowering of the lifting arm in the fixed frame. When the width of the stainless steel pipe is small, the spacing between the arc bending roller, the arc pressing roller and the limit arc pressing roller is reduced to adjust the fit to the stainless steel pipe. At the same time, the lifting arm squeezes the water pipe to reduce the water supply of the cleaning liquid in the water pipe. The support rod slides toward the middle under the squeezing of the water pressure in the water supply pipe and the squeezing force of the spring rod, thereby adjusting the clamping degree of the round tube roller on both sides of the stainless steel pipe. When the width of the stainless steel pipe is large, the same applies, thereby facilitating the adjustment of the spacing to control the fit squeezing degree and improve the cleaning effect of the cleaning liquid.

[0020] 3. The present invention designs devices such as square tube rollers, slides and telescopic rods, and uses a water pump to transport the cleaning liquid from the water collecting tank of the welding table to the fixed frame and the slide, so that the telescopic rod on the fixed frame is extended by hydraulic pressure, and the buckle is pushed out by hydraulic pressure to fix the lifting height, so that the square tube roller squeezes the pipe into other shapes.

[0021] 4. The present invention designs devices such as inclined plates and water collecting plates. When the support rod slides toward the slide table, the inclined plates and alignment plates on the support rod cross to lift and lower the water collecting plates synchronously. The water collecting plates are inclined and gradually lifted on the inclined plates and alignment plates, and the cleaning liquid flowing out after pickling in the water collecting plates is collected back into the fixed table for reuse.

DETAILED DESCRIPTION

[0031] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0032] See also Figures 1 to 8 The present invention provides a technical solution for a transfer device to prevent displacement during stainless steel pipe processing:

[0033] A transfer device for preventing displacement during stainless steel pipe processing, comprising a limit roller 2, a limit plate 3, a fixed plate 6 and a welding table 11, wherein the limit plate 3 is symmetrically mounted on the limit roller 2 and is movably arranged, the fixed plate 6 is located on one side of the welding table 11, a distance measuring sensor is arranged in the limit roller 2, fixed frames 7 are fixedly mounted on both sides of the fixed plate 6, a water guide pipe 701 is installed through the middle of the fixed frame 7, lifting arms 702 are symmetrically mounted on the upper and lower ends of the water guide pipe 701, and the lifting arms 702 are movably connected to the fixed frame 7, a bending roller 703 is installed in the middle of the lower lifting arm 702, a slide 8 is fixedly mounted in the middle of the fixed plate 6, support rods 802 are symmetrically mounted on both sides above the slide 8, an inclined plate 804 and an alignment plate 8041 are fixedly mounted on the inner sides of the support rods 802 on both sides, a water collecting plate 10 is fitted above the inclined plate 804 and the alignment plate 8041, and the water collecting plate 10 is fitted below the bending roller 703;

[0034] As an embodiment of the present invention, Figures 1 to 5 As shown, a water supply pipe 601 is provided in the fixed plate 6 on one side of the welding table 11, and the water supply pipe 601 is connected with a water guide pipe 701 through and through, the diameter of the water guide pipe 701 at both ends is gradually increased toward the middle, and the water guide pipe 701 is connected with a water spray pipe 9 through and through, a water spray pipe 9 is fixedly installed above the fixed frame 7, and a cleaning nozzle 901 is installed through and through on the water spray pipe 9;

[0035] During operation, since the limit plate 3 slides symmetrically on the limit roller 2, and a distance measuring sensor is provided in the limit roller 2, the sliding distance of the limit plate 3 is measured by the distance measuring sensor to measure the width of the stainless steel pipe. The width information is uploaded to the control console on the processing production line by the distance measuring sensor. The lifting arm 702 is controlled to rise and fall in the fixed frame 7 by the control console, and then the degree of fitting and squeezing of the stainless steel pipe is adjusted by adjusting the spacing between the arc bending roller 703, the arc pressing roller 704 and the limit arc pressing roller 705. When the width of the stainless steel pipe is small, the spacing between the arc bending roller 703, the arc pressing roller 704 and the limit arc pressing roller 705 is reduced by adjusting the control. Since the diameters of the two ends of the water pipe 701 are gradually increased toward the middle, the water pipe 701 is squeezed by the lifting arm 702 to reduce the water supply of the water pipe 701, and at the same time, the squeezing force of the water pressure in the water supply pipe 601 on the support rod 802 is increased. The support rod 802 is in the water supply The tube 601 slides toward the middle of the slide 8 under the extrusion of the water pressure in the tube and the spring rod to extrude the stainless steel pipe. When the width of the stainless steel pipe is large, the round tube roller 803 is adjusted to hold both sides of the stainless steel pipe. At the same time, the support rod 802 slides on the slide 8, and the arc roller 703 is attached to the top of the water collecting plate 10. The water collecting plate is crossed by the inclined plate 804 and the alignment plate 8041 on the support rod 802. 10 limit synchronous lifting and lowering. After the stainless steel pipe is processed into a pipe, the pipe diameter is smaller than the width, and the spacing between the round pipe roller 803, the arc bending roller 703, the arc pressing roller 704 and the limit arc pressing roller 705 gradually decreases from the fixed table 1 to the welding table 11. At this time, the water collecting plate 10 is inclined and gradually lifted on the inclined plate 804 and the alignment plate 8041, and the cleaning liquid flowing out of the water collecting plate 10 after pickling is collected back into the fixed table 1 for reuse.

[0036] As an embodiment of the present invention, Figures 3 to 8 As shown, a support frame 14 is fixedly installed above the welding table 11, a high-frequency heating tube 1401 is fixedly installed in the middle of the support frame 14, and a water pipe is embedded and installed around the wall of the high-frequency heating tube 1401, and heat-conducting sleeves 1402 are fixedly installed on both sides of the high-frequency heating tube 1401. Telescopic rods 15 are fixedly installed at both ends of the fixed frame 7 on the other side of the welding table 11, and buckles are provided in the telescopic rod 15. A square tube roller 16 is movably installed in the middle of the lifting arm 702 on the other side;

[0037] A water collecting tank and a water pump are provided in both the welding table 11 and the fixed table 1, and the water collecting tank in the welding table 11 is connected to an external water supply pipe, a four-way pipe is provided in the fixed plate 6 on the other side of the welding table 11, and the four-way pipe is connected to the support frame 14, the welding table 11, the sliding table 8 and the fixed frame 7, the four-way pipe is connected to the telescopic rod 15 through the fixed frame 7, the water collecting tank in the welding table 11 is connected to the water collecting tank in the fixed table 1, spring rods are provided on both sides of the sliding table 8, a heating coil 1403 is embedded on the inner side of the high-frequency heating tube 1401, and the water pipe on the inner wall of the high-frequency heating tube 1401 is connected to the support frame 14, and the support frame 14 is connected to the internal water pump of the welding table 11;

[0038] An elastic member 1301 is equidistantly mounted on the inner lower end of the limiting clamping roller 13, one end of each of the elastic members 1301 is fixedly connected to a push block 1302, and a closing plate 1303 is fixedly connected below the push block 1302. The elastic member 1301, the push block 1302 and the closing plate 1303 at the lower end of the limiting clamping roller 13 are arranged in the welding table 11, and the closing plate 1303 is installed between the water pump and the cross-tube in the welding table 11;

[0039] During operation, when the pipe is processed into other shapes, the cleaning liquid is provided to the water collecting tank in the welding table 11 through the external water supply pipe, and the cleaning liquid is transported from the water collecting tank of the welding table 11 to the fixed frame 7 and the slide 8 through the four-way pipe and the water pump. The round tube roller 803 on the slide 8 on the other side of the welding table 11 slides to both sides under the hydraulic pressure of the four-way pipe in the slide 8, and the telescopic rod 15 lifts the square tube roller 16 to clamp the pipe. When the telescopic rod 15 is extended by the hydraulic pressure of the cleaning liquid, the lifting roller 16 is pushed out by the buckle in the telescopic rod 15 under the hydraulic pressure. The height of the lifting is fixed, and then the telescopic rod 15 is hydraulically supported under the hydraulic pressure of the cleaning liquid, so that the square tube roller 16 squeezes the pipeline to form other shapes. When the shape change processing is cancelled, the cleaning liquid is transported and discharged by the water pump in the welding table 11, and a negative pressure suction force is formed in the four-way pipe through the flow of liquid, so that the buckle in the telescopic rod 15 is sucked back, and the telescopic rod 15 is extended to slide the square tube roller 16 to both sides to cancel the squeezing of the pipeline. At this time, the round tube roller 803 slides to the middle under the spring rod in the slide 8 to reset, so as to assist the transfer of the pipeline;

[0040] When the pipeline transfer is slow (for example, when the friction between the transfer part and the steel or pipeline is large in some parts during transportation, or when the resistance of the cutting knife is large when cutting the welding position), the pipeline stays in the high-frequency heating tube 1401 for a long time. At this time, the rotation speed of the limiting clamping roller 13 in contact with the pipeline is reduced, so that the elastic part 1301 pushes the push block 1302 under the elastic potential energy to make the closing plate 1303 slide inward and shrink, thereby increasing the water delivery of the four-way pipe to the support frame 14. By increasing the water delivery in the support frame 14, the water flow rate of the water pipe on the inner wall of the high-frequency heating tube 1401 is increased. At this time, through The water with a relatively low temperature initially flows in the water pipe and the heat-conducting sleeve 1402 to improve the effect of heat exchange, thereby reducing the temperature in the high-frequency heating tube 1401, thereby reducing the heating temperature of the pipeline by the heating coil 1403 in the high-frequency heating tube 1401, so as to prevent the pipeline from staying in the high-frequency heating tube 1401 for a long time and deforming under high temperature. When the pipeline is transferred faster or at a normal rate, it can be obtained by the same logic that the speed of the limit clamping roller 13 is increased, and the push block 1302 makes the closing plate 1303 slide and expand outward to reduce the water flow, so as to prevent the water flow from being too much and too fast and reducing the heating effect of the heating coil 1403 on the pipeline;

[0041] Secondly, when the pipeline transfer is slow and the pipeline transfer is fast or the transfer is at a normal rate, the water temperature is heat exchanged through the water pipe in the high-frequency heating tube 1401 and the heat-conducting sleeve 1402, so that the cleaning liquid in the water pipe is quickly heated when the pipeline transfer is slow. When the pipeline transfer is fast or the transfer is at a normal rate, the water delivery volume and flow rate are reduced, so that the cleaning liquid in the water pipe in the high-frequency heating tube 1401 is circulated as a water vapor coexistence body under high temperature heating. Since the water collecting tank in the welding table 11 is connected with the water collecting tank in the fixed table 1, when the transfer is slow, the heated cleaning liquid is directed to the welding table 11 through the welding table 11. In the water collecting box in the fixed table 1, the cleaning nozzle 901 is used to spray cleaning liquid for high-temperature cleaning of steel parts. When the transfer is faster or at a normal rate, water vapor is sprayed from the cleaning nozzle 901. Since the temperature of the water vapor is high, the pulling force of the sprayed water vapor is larger, thereby reducing the amount of water sprayed while maintaining the cleaning effect. Secondly, the steel is heated and cleaned by the heated cleaning liquid or the cleaning liquid in the water vapor state to reduce the rigidity of the steel, facilitate the deformation of the steel during the transfer process, and prevent the steel from rebounding under the rigid force and affecting the positioning, thereby facilitating the deformation processing of the steel while improving the positioning effect of the steel during transfer.

[0042] As an embodiment of the present invention, Figure 6 and Figure 7 As shown, a baffle 12 is fixedly installed on one side of the upper side of the welding table 11, a welding head 1201 is embedded and installed on one side of the baffle 12, and a limited clamping roller 13 is fixedly installed on the other side of the baffle 12. A cutting knife is provided below the baffle 12, and the cutting knife is located between the welding head 1201 and the high-frequency heating tube 1401;

[0043] During operation, the stainless steel pipe steel is clamped by the limiting clamping roller 13 and transferred to the welding head 1201 for welding operation, so that the stainless steel pipe steel closed on both sides is welded and made into a pipe for use. Secondly, the welding slag raised during welding is cut and removed by a cutter, and then the pipe is heated by the high-frequency heating tube 1401 and subjected to subsequent cooling treatment, thereby increasing the rigidity of the pipe.

[0044] As an embodiment of the present invention, Figures 1 to 5 As shown, a fixed platform 1 is provided below the limiting roller 2, and the limiting roller 2 is movably connected with the fixed platform 1, a steel feeding roller 4 is provided on one side of the limiting roller 2, and the steel feeding roller 4 is movably connected with the fixed platform 1, a distribution roller 5 is provided on one side of the steel feeding roller 4, and the distribution roller 5 is fixedly connected with the fixed platform 1, a water collecting tank and a water pump are provided on the inner side of the fixed platform 1, and the water collecting tank is connected with the water collecting plate 10;

[0045] During operation, the stainless steel material to be processed is passed through the limiting roller 2, and the steel material is limited on both sides by the limiting plate 3. Since the limiting roller 2 is movably arranged in an embedded manner in the fixed table 1, the limiting plate 3 is symmetrically movably arranged on the limiting roller 2. The limiting roller 2 and the limiting plate 3 are movably adjusted to adjust the distance with the steel material and limit the position during feeding processing, thereby preventing the stainless steel material from being displaced when being processed into a pipeline. The steel feeding roller 4 is used to clamp and feed the steel material during the stainless steel pipeline processing, and the distribution roller 5 is used to distribute and divert the steel material to the middle of the arc pressing roller 704 and the arc bending roller 703, thereby transferring the steel pipeline for use. Secondly, the cleaning liquid in the water collecting tank is pressurized by the water pump in the fixed table 1 and finally transported to the cleaning nozzle 901 for spraying, thereby pickling the steel pipeline for use.

[0046] As an embodiment of the present invention, Figures 1 to 5 As shown, a rotating shaft 7021 is provided on the inner side of the lifting arm 702, a plurality of fixed plates 6, fixed frames 7 and slides 8 are arranged in sequence, arc pressing rollers 704 and limiting arc pressing rollers 705 are alternately installed on the fixed frame 7, and the arc pressing rollers 704 and limiting arc pressing rollers 705 are both engaged and movably connected with the rotating shaft 7021, an arc-shaped groove is provided on the arc bending roller 703, and the arc pressing rollers 704 and limiting arc pressing rollers 705 are both engaged and arranged with the groove on the arc bending roller 703, a slide groove 801 is provided on the inner side of the slide 8, and a support rod 802 is engaged and movably arranged in the slide groove 801, and a round tube roller 803 is engaged and movably installed above the support rod 802;

[0047] During operation, since the arc bending roller 703 is provided with an arc-shaped groove, and the arc pressing roller 704 and the limiting arc pressing roller 705 are arranged in close contact with the groove, the stainless steel pipe steel is clamped and squeezed by multiple arc pressing rollers 704 and the limiting arc pressing roller 705, so that the stainless steel pipe steel gradually becomes a round tube in the groove of the arc bending roller 703. When gradually forming, since the limiting arc pressing roller 705 has a limiting block in the middle and grooves on both sides of the limiting block, the two sides of the stainless steel pipe steel are contracted and formed during the forming transfer. And limit the position, thereby preventing the pipeline steel from shifting during transfer, and operating on the lifting arm 702 through the rotating shaft 7021, so that the bending roller 703, the arc pressing roller 704 and the limiting arc pressing roller 705 rotate to clamp, transfer and shape the pipeline steel. Secondly, the support rod 802 slides on the slide 8 through the slide groove 801 to adjust the spacing, and the round tube roller 803 squeezes the two sides of the arc-shaped stainless steel pipeline steel inward to make it gradually close, thereby processing and shaping the stainless steel pipeline steel.

[0048] Working principle: During operation, the spacing between the steel and the limit roller 2 and the limit plate 3 is adjusted to prevent displacement of the stainless steel pipe during processing. The stainless steel pipe and steel are fed by the steel feeding roller 4, and the steel is divided and diverted by the dividing roller 5 for transfer processing. Secondly, the cleaning liquid in the water collection tank is transported to the cleaning nozzle 901 through the water pump in the fixed platform 1 for spraying, so as to pickle the steel pipe;

[0049] At the same time, when the support rod 802 slides onto the slide table 8, the inclined plate 804 and the alignment plate 8041 on the support rod 802 cross to synchronously lift and lower the water collecting plate 10, and the cleaning liquid flowing out after pickling in the water collecting plate 10 is collected back into the fixed table 1 for reuse;

[0050] The distance of the limit plate 3 is measured by the distance measuring sensor to measure the width of the stainless steel pipe, and the width information is uploaded to the control console on the processing production line through the distance measuring sensor, and the lifting arm 702 is controlled to rise and fall in the fixed frame 7 through the control console, so as to adjust the degree of fit and extrusion of the stainless steel pipe by the arc bending roller 703, the arc pressing roller 704 and the limit arc pressing roller 705. The rotating shaft 7021 operates on the lifting arm 702, so as to rotate the arc bending roller 703, the arc pressing roller 704 and the limit arc pressing roller 705 to clamp and transfer the pipe steel. When the width of the stainless steel pipe is small, the arc bending roller 703 and the arc pressing roller 704 are adjusted. , the spacing of the limiting arc-pressing rollers 705 is reduced, and the water pipe 701 is squeezed by the lifting arm 702 to reduce the water supply of the water pipe 701, and at the same time, the squeezing force of the water pressure in the water pipe 601 on the support rod 802 is increased. The support rod 802 slides toward the middle of the slide 8 under the squeezing of the water pressure in the water pipe 601 and the squeezing of the spring rod. When the width of the stainless steel pipe is large, the same is true on the contrary, and then the clamping degree of the round tube roller 803 on both sides of the stainless steel pipe is adjusted, and the round tube roller 803 squeezes the two sides of the arc-shaped stainless steel pipe inward to gradually close the stainless steel pipe, and then the stainless steel pipe is processed and formed;

[0051] When the pipe is processed into other shapes, the cleaning liquid is transported from the water collecting tank of the welding table 11 to the fixed frame 7 and the sliding table 8 through the water pump, so that the telescopic rod 15 on the fixed frame 7 is pushed out by the hydraulic pressure, and the buckle is pushed out under the hydraulic pressure to fix the lifting height, so that the square tube roller 16 squeezes the pipe into other shapes. When the shape change processing is cancelled, the cleaning liquid is transported and discharged through the water pump in the welding table 11, so that the telescopic rod 15 is extended and retracted to slide the square tube roller 16 to both sides to cancel the squeezing of the pipe. At this time, the round tube roller 803 slides to the middle under the spring rod and resets to assist in the transfer of the pipe.

[0052] When the pipe is transferred slowly, the rotation speed of the limiting clamping roller 13 in contact with the pipe is reduced, and then the elastic member 1301 pushes the push block 1302 under the elastic potential energy to make the closing plate 1303 slide and shrink inward, thereby increasing the water flow rate of the water pipe on the inner wall of the high-frequency heating tube 1401. The water with an initial low temperature flows in the water pipe and the heat-conducting sleeve 1402 improves the heat exchange effect, thereby reducing the temperature in the high-frequency heating tube 1401 and the temperature of the heating pipe to prevent the pipe from deforming at high temperature. When the pipe is transferred quickly or at a normal speed, it can be obtained by the same logic that the rotation speed of the limiting clamping roller 13 is increased, and the push block 1302 makes the closing plate 1303 slide and expand outward to reduce the water flow rate to prevent the heating effect on the pipe from being reduced.

[0053] Secondly, the water temperature is heat exchanged through the water pipe and the heat-conducting sleeve 1402. When the pipeline transfers slowly, the cleaning liquid in the water pipe is quickly heated and used. When the pipeline transfers quickly or at a normal rate, the cleaning liquid in the water pipe is made to circulate as a water vapor coexistent body under heating. When the transfer is slow, the heated cleaning liquid is guided to the water collecting tank in the fixed table 1 through the welding table 11, so that the cleaning nozzle 901 sprays cleaning liquid to clean the steel parts at high temperature. When the transfer is fast or at a normal rate, water vapor is sprayed from the cleaning nozzle 901, thereby reducing the water spraying amount while maintaining the cleaning effect. The steel is heated and cleaned by the heated cleaning liquid or the cleaning liquid in a water vapor state, which facilitates the deformation of the steel during the transfer process and improves the positioning effect of the steel during transfer.
