Detailed Description
Embodiments of the present invention will now be described with reference to the accompanying drawings.
Example 1
The automatic production line of the sectional materials comprises a forming station 5, a surface brightening treatment station 6, a cleaning station 7 and a packaging station 8 which are sequentially arranged, wherein the sectional materials formed by the forming station 5 continuously pass through the surface brightening treatment station 6, the cleaning station 7 and the packaging station 8; the continuous passing of the section bar is realized between the stations by arranging a conveying and transferring mechanism; such transport and transfer mechanisms have a great number of technical solutions in the prior art, which are not discussed here; in this embodiment, the cleaning station 7 includes a feeding area 1, a cleaning tank 2, a discharging area 3, and a conveying mechanism for obliquely carrying the section bar away from the liquid surface of the cleaning tank 2, which are sequentially arranged; the conveying mechanism is a structure for enabling the section bars to sequentially pass through the feeding area 1, the cleaning tank 2 and the discharging area 3 along a smooth curve path with high and low fluctuation.
The front of the cleaning station 7 is provided with a feeding mechanism capable of moving the section bar from the previous station to the feeding area 1, and the rear of the cleaning station 7 is provided with a discharging mechanism capable of moving the section bar from the discharging area 3 to the next station.
The profile can be an aluminum alloy pipe, a galvanized steel pipe and the like.
In order to prevent the profile from floating up due to the instant large buoyancy change when the profile enters, the conveying mechanism is used for obliquely conveying the profile into the cleaning tank, one end of the profile firstly enters the liquid level, and then one end of the profile firstly leaves the liquid level. The liquid level can be continuously kept at a single point, the cleaning time difference under the liquid level can be ensured to be close to zero, and the cleaning effect stability is better. The concrete operation method is that the conveying mechanism adjusts the section bar to the opposite inclined direction under the liquid surface, so that one end which enters the liquid surface first leaves the liquid surface before the other end.
As shown in fig. 1, the cleaning station 7 may comprise a plurality of cleaning tanks arranged in series, for example, a first cleaning tank is used for placing chemical cleaning liquid, and a subsequent cleaning tank is used for placing clean water, etc. After the section bar is sent out of one cleaning tank 2 by the conveying mechanism, the section bar is continuously sent into the next cleaning tank 2 until the section bar is sent out of the last cleaning tank 2. The continuous automatic conveying function of the section bar among various cleaning solutions is realized, and the continuous automatic conveying device is more suitable for multiple cleaning processes in actual production. After the section bar is sent out of the last cleaning pool 2 by the conveying mechanism, the section bar can be sent into a drying device arranged in a discharging area or at the rear of the discharging area for drying. Directly obtaining a clean and dry finished product of the section bar, and realizing automatic operation in the whole process from the output to the cleaning and the storage of the section bar.
The cleaning station 7 can also realize the function of draining while solving the problem of deformation due to the inclination away from the liquid level. In order to further enhance the draining effect, air is supplied to one end of the profile, which is firstly separated from the liquid surface, above the liquid surface, and the air supply direction is the same as the extending direction of the profile. Still further strengthen the effect, conveying mechanism is after the both ends of section bar all leave the liquid level, and pause time T resumes the transport again. The air supply is still kept in the suspension time T, so that the liquid carried by the profile away from the cleaning tank can be drained in the corresponding cleaning tank, and the profile cannot be carried to the next cleaning tank to cause inter-tank pollution. The time T may vary from 3 seconds to 1 minute.
The embodiment of the invention is shown in fig. 1, and is an automatic profile production line for producing aluminum alloy pipes. The forming station 5 comprises an unreeling station 51, a tubular forming station 52, a destressing station 53, arranged in succession. Wherein the unreeling station 51 is used for unreeling the rolled aluminum alloy sheet coiled material; the tubular forming station 52 is used for bending the unreeled sheet aluminum alloy into a tubular shape and welding and forming; the stress relieving station 53 is used for relieving residual stress in the aluminum alloy pipe by a heat treatment mode and prolonging the service life of the aluminum alloy pipe.
The surface brightening treatment station 6 comprises a polishing station, and the polishing of the aluminum alloy pipe can adopt a grinding wheel or shot blasting to improve the fatigue strength, the wear resistance, the roughness and the like of the aluminum alloy pipe.
Cutting stations may be provided between the forming station 5 or the surface brightening station 6 or in both stations for cutting the strip of aluminium alloy tube into lengths of equal length as required in preparation for a subsequent cleaning process. The aluminum alloy pipe after passing through the surface brightening treatment station 6 is moved to the feeding area 1 of the cleaning station 7 by a feeding mechanism. The feeding mechanism can adopt a hanging rail capable of horizontally moving, an electric control clamping piece for clamping the aluminum alloy pipe is arranged on the hanging rail, and a limiting pin transversely extending into or moving out of the inner sides of two ends of the aluminum alloy pipe in an electric control mode can be also adopted on the hanging rail. The discharging mechanism can adopt the same structure as the feeding mechanism.
The conveying mechanism in the cleaning station 7 comprises a first conveying chain 11 and a second conveying chain 12 which are arranged in parallel, a plurality of supporting pieces used for supporting the transversely arranged sectional materials are arranged on the first conveying chain 11 and the second conveying chain 12 along the extending direction of the first conveying chain 11 and the second conveying chain 12, V-shaped grooves for placing aluminum alloy tubes are formed in the supporting pieces, the first conveying chain 11 and the second conveying chain 12 extend into and out of the cleaning pool 2 respectively, and a section of the cleaning pool, which is separated from the liquid surface 10, forms unequal included angles alpha 1 and beta 1 with the liquid surface respectively. Because the included angles alpha 1 and beta 1 are unequal, the velocity components of the two ends of the profile at the vertical height are different, the larger the included angle is, the larger the velocity component is, and the corresponding one end reaches the liquid level faster than the other end.
The first conveying chain 11 and the second conveying chain 12 enter a section of the liquid surface 12 to form unequal included angles alpha 2 and beta 2 with the liquid surface 12 respectively. The principle is as above, and the effect that one end of the section firstly enters the liquid level is realized by utilizing the difference of components of the speed in the vertical direction. In combination with the above-mentioned technical features of "a section leaving the liquid surface 10 forms respectively unequal angles α1 and β1 with the liquid surface", a cleaning step of "adjusting the profile to an opposite oblique direction under the liquid surface" can also be achieved. The specific principle is that, taking fig. 2 as an example, the first conveying chain 11 and the second conveying chain 12 are respectively arranged in the feeding area 1 and the discharging area 2 in a horizontal and parallel manner. The included angle alpha 2 is smaller than the included angle beta 2, so that one end of the profile supported by the second conveying chain descends faster after leaving the feeding area, and enters the liquid level 10 first. One end of the section bar corresponding to the second conveying chain reaches the bottom of the cleaning pool first and then rises in a turning way, and at the moment, the other end of the section bar corresponding to the first conveying chain also keeps the descending direction. I.e. it is achieved that the profile is adjusted to an opposite tilting direction under the liquid surface, and then the end of the profile corresponding to the second conveyor chain rises relatively slowly and leaves the liquid surface 10 first. According to the geometric triangular relationship, one end of the profile corresponding to the second conveying chain and the other end of the profile corresponding to the second conveying chain can reach the same horizontal plane at the same time when the profile reaches the discharging area 3 as long as the two conveying belts leave the feeding area and travel between the feeding area and the discharging area is the same at the same driving speed, and then the profile is horizontally sent out of the discharging area.
The lengths of the first conveyor chain 11 and the second conveyor chain 12 below the liquid surface may be unequal. Under the drive of the same speed, the conveying belt with longer length under the liquid level needs longer to leave the liquid level, so that the technical effect that two ends of the profile leave the liquid level asynchronously is realized. The technical means of unequal lengths can be combined with different implementation of the included angles, and also can be independently implemented.
In addition, the differential mechanism can also be used for enabling the transmission motor to output different driving speeds to the two conveying belts: the transmission motor is in transmission connection with the first conveying chain and is in transmission connection with the second conveying chain after passing through the differential mechanism. The end of the profile corresponding to the conveyor belt with higher driving speed enters the liquid level faster and leaves the liquid level faster.
In this embodiment, the supporting members on the first conveying chain 11 and the second conveying chain 12 are provided with V-shaped grooves, and the feeding mechanism and the discharging mechanism positioned in front of the cleaning station 7 may also adopt a conveyor belt capable of supporting the aluminum alloy pipe, the output end of the conveyor belt of the feeding mechanism is positioned above the feeding area 1, and the aluminum alloy pipe on the feeding mechanism can fall onto the V-shaped grooves of the supporting members after moving to the output end; the conveyer belt input of discharge mechanism is located the discharge zone 3 below, and after the aluminum alloy pipe on first conveyer chain 11 and the 12 support piece of second conveyer chain moved to the discharge zone 3, along with the downward rotation of first conveyer chain 11 and second conveyer chain 12, the aluminum alloy pipe on the support piece can drop to discharge mechanism's conveyer belt on, need not the manual work and carries.
After oil and dust removal through the cleaning station 7, the aluminum alloy pipe can directly enter the packaging station 8 for packaging, but in order to prolong the surface wear resistance and corrosion resistance of the aluminum alloy pipe, the aluminum alloy pipe can be treated between the cleaning station 7 and the packaging station 8 through the surface coloring treatment station 9. The treatment mode can be chromizing, paint spraying, electroplating, anodic oxidation or electrophoresis. The aluminum alloy pipe treated by the surface coloring treatment station 9 is packaged by an automatically controlled packaging station 8, and the packaging station 8 can adopt a plastic film packaging machine and a heating machine capable of shrinking the plastic film wrapped outside the section bar so as to realize the automatic production of a full production line.
Example 2
An automatic section bar production line for producing galvanized steel pipes comprises a forming station 5, a surface brightening treatment station 6, a cleaning station 7, a surface coloring treatment station 9 and a packaging station 8 which are sequentially arranged. If the steel pipe is a seamless pipe, the forming station 5 adopts a hot rolling or cold rolling mode to manufacture the seamless steel pipe; if the steel pipe is a welded pipe, the forming station 5 may use straight seam welding or spiral welding to manufacture the welded pipe. The formed steel pipe enters a stress relief station, and residual stress in the steel pipe is eliminated in a heat treatment mode, so that the service life of the steel pipe is prolonged.
The surface brightening treatment station 6 comprises a polishing station, and the polishing of the steel pipe can adopt a grinding wheel or a shot blasting treatment to improve the fatigue strength, the wear resistance, the roughness and the like of the aluminum alloy pipe.
Cutting stations may be provided between the forming station 5 or the surface brightening station 6 or in both stations for cutting the strip of steel pipe into lengths of equal length as required in preparation for a subsequent cleaning process.
In this embodiment, the conveying mechanism of the cleaning station 7 includes a supporting rod 21 for supporting the section bar, and a third conveying belt 22 for driving the supporting rod 21 to move, where the third conveying belt 22 extends into and out of the cleaning tank 2; one end of the supporting rod 21 freely extends, and the other end of the supporting rod is hinged with the support 23 and then connected with the third conveying belt 22; an adjusting mechanism for adjusting the included angle between the support rod 21 and the horizontal plane is also provided. The adjusting mechanism is a convex plate 24, which is arranged below the supporting rod 21, has the same extending direction as the third conveying belt 22, and has a section of height greater than the support 23 before leaving the liquid and a section of height less than the support 23 before entering the liquid. The free end of the supporting rod 21 is provided with a locking mechanism 25 for preventing the profile 4 from sliding down.
During working, the section bar (steel pipe) can be inserted into the support rod 21, and the support rod 21 swings around the support 23 to adjust the relative angle between the section bar and the liquid level. The convex plate 24 is used for supporting a section of the supporting rod 21 close to the support 23, and the height of the convex plate 24 relative to the support 23 can directly adjust the relative distance between the supporting rod 21 and the horizontal plane. The section leaving the liquid and the section entering the liquid have the height changed, so that the cleaning step of converting the inclined direction of the section under the liquid level is realized. Specifically, with the continuous conveying of the third conveying belt 22, the angle of the supporting rod 21 is continuously adjusted by the convex plate 24, and before entering the liquid, the convex plate 24 is lower in height, and one end of the supporting rod 21, which is close to the support 23, is higher than the horizontal plane, and one end of the supporting rod, which is far from the support 23, is lower than the horizontal plane, so that the section bar firstly enters the liquid level from one end of the supporting rod, which is far from the support 23, for cleaning. The height of the raised plate 24 varies continuously in the washing basin 2, the end of the bar 21 close to the support 23 starting below the horizontal plane and the end remote from the support 23 starting above the horizontal plane, so that the profile leaves the liquid surface first from the end remote from the support 23.
In this embodiment, since the steel pipe is supported by the supporting rod 21 in the conveying mechanism, the feeding mechanism and the discharging mechanism may each employ a cylinder pushing rod. After the steel pipe is processed by a station positioned in front of the cleaning station 7, the steel pipe is moved to a state of being arranged coaxially with the supporting rod 21, and one end of the steel pipe is pushed by a cylinder push rod to move towards the other end along the extending direction and is sleeved outside the supporting rod 21. When the steel pipe passes through the discharging area 3, the steel pipe is pulled out through a discharging mechanism, the discharging mechanism comprises an air cylinder push rod and a pneumatic claw positioned at the top of the push rod, one end of the steel pipe is clamped through the pneumatic claw, and the steel pipe can be pulled out through the extension and retraction of the air cylinder push rod. The locking mechanism 25 may be installed or removed by another set of cylinders, or by increasing friction between the strut 21 and the inner side of the steel pipe to prevent the steel pipe from sliding down when the strut 21 is tilted. The discharging can also be realized by inclining the support rod 21 and utilizing the gravity of the steel pipe to slide off from the support rod 21.
After the cleaned steel pipe enters the surface coloring treatment station 9, the surface coloring treatment station 9 carries out a galvanization process on the steel pipe, and a hot dip plating or electroplating mode can be adopted, so that the galvanization can increase the corrosion resistance of the steel pipe and prolong the service life. The galvanized steel pipe can be packaged through the automatically controlled packaging station 8.
Example 3
The conveying mechanism of the cleaning station 7 comprises a first suspension arm 31 and a second suspension arm 32 which are arranged in parallel, and a transmission mechanism 33 for driving the two suspension arms to sequentially pass through the feeding area 1, the cleaning tank 2 and the discharging area 3; the two hanging arms are hung above the feeding area 1, the cleaning tank 2 and the discharging area 3, the upper ends of the two hanging arms are respectively connected with the transmission mechanism 33, the lower ends of the two hanging arms extend downwards freely and are respectively provided with the clamping mechanisms 34 for clamping the sectional materials, and the middle parts of the two hanging arms are respectively provided with the length adjusting mechanisms 35. The clamping mechanism 34 can be used as a feeding mechanism in front of the cleaning station 7 and a discharging mechanism behind the cleaning station 7, and no additional components are needed.
After the two suspension arms clamp the section bar, the relative distance between the two suspension arms and the cleaning tank is realized through the length adjusting mechanism, so that the inclination angle of the section bar is adjusted. For example, in the conveying process, the two clamping mechanisms stably clamp the section bar in the feeding area, the section bar is in a horizontal state at this time, then the transmission mechanism 33 drives the two suspension arms to enter the cleaning tank 2, the two length adjusting mechanisms 35 enable the two suspension arms to extend into the liquid level respectively, and the extending speed of the first suspension arm 31 is greater than that of the second suspension arm, so that one end of the section bar close to the first suspension arm 31 enters the liquid level first. After cleaning, the two suspension arms are retracted by the length adjusting mechanism, and the retraction speed of the first suspension arm 31 is higher than that of the second suspension arm 32, so that one end of the section bar, which is close to the first suspension arm 31, firstly leaves the liquid level. I.e. the adjustment rate of the length adjustment mechanism 35 corresponding to the first boom 31 is greater than the adjustment rate of the length adjustment mechanism 35 corresponding to the second boom 32.
