Abstract
Description
Technical Field
[0001] The present application relates to the technical field of angle steel processing, and in particular to a spray passivation device for angle steel. Background Art
[0002] During the post-plating treatment of angle steel, it is usually necessary to spray passivation liquid on the surface of the angle steel, so as to form a surface state on the surface of the coating that can prevent the normal reaction of the metal, improve its corrosion resistance, and increase the appearance of the product.
[0003] A common cleaning method is to drive the angle steel to move and pass through a spray ring that is adapted to the cross-section of the angle steel. At this time, passivation liquid is introduced into the spray ring. Since the inner wall of the spray ring close to the feeding side of the angle steel is inclined toward the side close to the angle steel and away from the feeding end of the angle steel, and a plurality of evenly distributed liquid outlet holes are provided on the inclined side of the spray ring, the passivation liquid entering the spray ring moves toward the angle steel through the liquid outlet holes, thereby completing the treatment of spraying the passivation liquid on the surface of the angle steel during the movement of the angle steel.
[0004] In the related art, the passivation liquid is sprayed onto the angle steel through a plurality of evenly distributed liquid outlet holes on a spray ring. Since there is a gap between two adjacent liquid outlet holes, it is easy to cause the passivation liquid to be difficult to be evenly distributed on the surface of the angle steel, thereby adversely affecting the quality of the finished angle steel. Summary of the invention
[0005] In order to reduce the adverse effects on the quality of angle steel products, the present application provides a spray passivation device for angle steel.

[0007] By adopting the above technical solution, the angle steel is driven to move from the feed port to the discharge port and pass through the recovery bin. At this time, the end of the angle steel passes through the spray ring, and the passivation liquid in the liquid delivery pipe is pressurized by the pressurizing component of the liquid delivery pipe, and the pressurized passivation liquid is passed into the spray ring, so that the increase in the area of the liquid outlet hole does not affect the spraying of the passivation liquid onto the surface of the angle steel. At this time, the passivation liquid inside the spray ring moves to the surface of the angle steel through the liquid outlet hole, so that the passivation liquid on the surface of the angle steel is evenly sprayed, reducing the adverse effects on the quality of the finished angle steel products.
[0008] Optionally, the pressurizing component includes a plurality of blades arranged inside the liquid delivery pipe and evenly distributed along the circumference of the inner wall of the liquid delivery pipe, the blades are spirally arranged along the rotation axis of the liquid delivery pipe, and a pressurizing cylinder located on the side of the blades close to the spray ring is fixedly connected to the liquid delivery pipe, and the pressurizing cylinder is arranged in a cone shape whose diameter gradually decreases toward the side close to the spray ring, and a guide fan is installed in the liquid delivery pipe, which is installed on the side of the blades away from the pressurizing cylinder and guides flow into the spray ring, and a rotating component for driving the guide fan to rotate is provided on the liquid delivery pipe.
[0009] By adopting the above technical solution, the rotating component drives the guide fan to rotate, thereby facilitating driving the passivation liquid in the liquid delivery pipe to move toward the direction close to the spray ring. The passivation liquid in the liquid delivery pipe moves to the blades. At this time, the spiral blades guide the passivation liquid, so that the passivation liquid moves in a spiral shape toward the spray ring. When the spirally moving passivation liquid moves into the pressurizing cylinder, the shape of the pressurizing cylinder further pressurizes the passivation liquid, so that the increase in the area of the liquid outlet hole does not affect the effect of spraying the passivation liquid onto the surface of the angle steel, thereby reducing the adverse effects on the quality of the finished angle steel products.
[0010] Optionally, the rotating assembly includes a worm wheel sleeved on the circumference of the guide fan, the worm wheel passes through the side wall of the liquid delivery pipe and is rotatably connected to the inner wall of the liquid delivery pipe, the outer side of the liquid delivery pipe is rotatably connected to a worm that cooperates with the worm wheel, the side of the worm close to the inside of the liquid delivery pipe is inserted into the side wall of the liquid delivery pipe and meshes with the worm wheel, and one end of the worm is equipped with a first motor fixedly connected to the outer wall of the liquid delivery pipe.
[0011] By adopting the above technical solution, the first motor drives the worm to drive the worm wheel to rotate, and the guide fan fixed to the worm wheel rotates at this time, thereby facilitating driving the passivation liquid in the liquid delivery pipe to move toward the direction close to the spray ring and pressurized by the blades and the pressure cylinder, so that the increase in the area of the liquid outlet hole does not affect the effect of spraying the passivation liquid onto the surface of the angle steel, thereby reducing the adverse effects on the quality of the finished angle steel products.
[0012] Optionally, the spray ring is slidably connected with baffles adapted to the side walls of the angle steel, the baffles can be spliced together into a ring shape adapted to the through hole and block the liquid outlet, the baffles are located on the side of the liquid outlet away from the through hole, and the spray ring is provided with a control component for driving the baffles to block the liquid outlet.
[0013] By adopting the above technical solution, when the liquid delivery pipe introduces passivation liquid into the spray ring, the baffle is driven by the control component to move in the direction close to the through hole until they are spliced with each other. At this time, the liquid outlet is blocked until the passivation liquid output by the liquid delivery pipe quickly fills the inside of the spray ring. At this time, the baffle is driven to move and open the liquid outlet at the same time, so that the passivation liquid inside the spray ring moves to the surface of the angle steel through the liquid outlet. At this time, liquid is discharged from all parts of the liquid outlet at the same time, reducing the possibility of uneven liquid discharge from all parts of the liquid outlet, and further reducing the adverse effects on the quality of the finished angle steel.
[0014] Optionally, the control component includes a driving rod fixedly connected to the side of the baffle away from the through hole and corresponding to the baffle one by one, the driving rods are perpendicular to the length direction of the baffle, the ends of the driving rods away from the corresponding baffles pass through the side wall of the spray ring and are slidably connected to the spray ring, the ends of the driving rods away from the corresponding baffles are sleeved with a first spring, one end of the first spring is fixedly connected to the corresponding end of the driving rod, and the other end is fixedly connected to the outer wall of the spray ring, when the first spring is at its original length, the liquid outlet is not blocked, and a moving part for driving the driving rod to move is provided on the spray ring.
[0015] By adopting the above technical solution, the moving part drives the driving rod to drive the baffle to move in the direction close to the through hole until the baffles are spliced with each other. At this time, the liquid outlet is blocked, which facilitates the passivation liquid to quickly fill the inside of the spray ring. At this time, the first spring is compressed. When the liquid outlet needs to be opened, the moving part moves in the direction away from the driving rod, and the first spring restores its deformation and opens the liquid outlet, thereby facilitating the uniform spraying of the passivation liquid onto the surface of the angle steel, reducing the adverse effects on the quality of the finished angle steel.
[0016] Optionally, the movable member includes two movable plates which are relatively arranged on both sides in the length direction of the spray ring and arranged along the height direction of the spray ring, the ends of the driving rods on both sides in the length direction of the spray ring away from the corresponding baffle plates are abutted against the corresponding side walls of the movable plate, the upper ends of the movable plates are penetrated and threadedly connected with a same two-way screw rotatably connected to the outer side wall of the liquid delivery pipe, the two driving rods located on the lower side of the spray ring away from the corresponding baffle plates are fixed to each other and fixedly connected with a same rack arranged along the height direction of the spray ring, the two-way screw is sleeved and fixedly connected with a first gear meshing with the upper end of the rack, the worm is sleeved with a second gear fixedly connected, the two-way screw is sleeved and slidably connected with a third gear meshing with the second gear, and a sliding assembly that drives the third gear to slide is provided on the upper side of the spray ring.
[0017] By adopting the above technical solution, the first motor drives the worm to drive the second gear to rotate. At this time, the third gear drives the bidirectional lead screw to rotate under the drive of the second gear, so that the movable plate moves in the direction of approaching each other and pushes the driving rods on both sides of the spray ring to drive the corresponding baffle to move in the direction close to the through hole. At this time, the first gear rotates with the bidirectional lead screw and drives the driving rod on the lower side of the spray ring through the rack to drive the corresponding baffle to move in the direction close to the through hole until the baffles are spliced with each other and block the liquid outlet. At this time, the third gear is driven by the sliding assembly to slide and disengage from the second gear, so that the baffle position is fixed by the bidirectional lead screw, so that the passivation liquid can quickly fill the inside of the spray ring.
[0018] The transmission gear of the present invention is a gear selected from the group consisting of a first gear and a second gear matched with the gear of the first gear and a second gear matched with the gear of the first gear.
[0019] By adopting the above technical solution, the moving plate drives the driving rod to move the baffle, and the baffle corresponding to the sliding rod moves and squeezes the inclined surface on the sliding rod, thereby driving the sliding rod to move upward. At this time, the upper end of the sliding rod contacts the outer wall of the driving ring and drives the third gear to move to the side away from the second gear along the inclined surface of the outer wall of the driving ring. When the baffles are spliced with each other, the third gear and the second gear are completely disengaged. At this time, the third gear is driven by the first hydraulic cylinder to continue to move and move away from the second gear, thereby reducing the possibility of the second gear continuing to drive the third gear to continue to rotate, and improving the stability of the baffle blocking. When the liquid outlet needs to be opened, the reset member drives the moving plate and the third gear to reset. At this time, the first spring recovers its deformation and pulls the driving rod and the baffle to move in a direction away from the through hole and open the liquid outlet, so as to facilitate the uniform spraying of passivation liquid onto the surface of the angle steel.

[0021] By adopting the above technical solution, the connecting component connects the second motor and the bidirectional screw. At this time, the second motor drives the bidirectional screw to rotate and drives the movable plate to move away from each other, and the first gear is reversed. At this time, the first spring restores its deformation and drives the baffle to move away from the through hole, thereby opening the liquid outlet. At this time, the sliding rod moves downward under the drive of the second spring, and the third spring partially restores its deformation, so as to facilitate the uniform spraying of passivation liquid onto the surface of the angle steel.
[0022] Optionally, the connecting assembly includes a second hydraulic cylinder located on a side of the second motor close to the bidirectional screw and fixedly connected to the output shaft of the second motor, the telescopic rod of the second hydraulic cylinder faces the bidirectional screw and is fixedly connected to a connecting block, the connecting block is coaxial with the bidirectional screw and can be inserted into the end of the bidirectional screw, and a monitoring device for controlling the rotation of the second motor is provided in the spray ring.
[0023] By adopting the above technical solution, the monitoring component monitors that the passivation liquid fills the spray ring. At this time, the second hydraulic cylinder drives the connecting block to be inserted into the bidirectional screw. At this time, the second motor drives the bidirectional screw to reverse through the second hydraulic cylinder and the second connecting block, and at this time, the telescopic rod of the first hydraulic cylinder contracts, thereby facilitating the driving of the baffle to reset, and at this time, the third gear and the second gear are not engaged, so that the liquid outlet is opened and the passivation liquid is evenly sprayed onto the surface of the angle steel.
[0024] Optionally, the monitoring device includes a first pressure gauge installed on the upper side of the spray ring and connected to the interior of the spray ring, and a second pressure gauge installed on the lower side of the spray ring and connected to the interior of the spray ring. The first pressure gauge and the second pressure gauge are both radio-connected to a control host, and the control host is radio-connected to the second motor.
[0025] By adopting the above technical solution, the first pressure gauge and the second pressure gauge respectively monitor the pressure on the upper and lower sides inside the spray ring. When the values monitored by the first pressure gauge and the second pressure gauge are the same, an electrical signal is transmitted to the control host, so that the control host drives the second motor to rotate, so as to drive the liquid outlet to open and evenly spray the passivation liquid onto the surface of the angle steel.
[0026] In summary, the present application includes at least one of the following beneficial technical effects: The angle steel is driven to move from the feed port to the discharge port and pass through the recovery bin. At this time, the end of the angle steel passes through the spray ring, and the passivation liquid in the liquid delivery pipe is pressurized by the pressurizing component of the liquid delivery pipe, and the pressurized passivation liquid is passed into the spray ring, so that the increase in the area of the liquid outlet hole does not affect the spraying of the passivation liquid to the surface of the angle steel. At this time, the passivation liquid inside the spray ring moves to the surface of the angle steel through the liquid outlet hole, so that the passivation liquid on the surface of the angle steel is evenly sprayed, reducing the adverse effect on the quality of the finished angle steel; The first motor drives the worm to drive the second gear to rotate. At this time, the third gear drives the bidirectional lead screw to rotate under the drive of the second gear, so that the movable plate moves in the direction of approaching each other and pushes the driving rods on both sides of the spray ring to drive the corresponding baffle to move in the direction close to the through hole. At this time, the first gear rotates with the bidirectional lead screw and drives the driving rod on the lower side of the spray ring through the rack to drive the corresponding baffle to move in the direction close to the through hole until the baffles are spliced with each other and block the liquid outlet hole. At this time, the third gear is driven to disengage from the second gear through the sliding assembly, so that the baffle position is fixed by the bidirectional lead screw, so that the passivation liquid can quickly fill the inside of the spray ring; The monitoring component detects that the passivation liquid fills the spray ring.

[0035] The spray ring 2 is located on the upper side of the workbench 13. The spray ring 2 is adapted to the cross-sectional shape of the angle steel, and the tip of the spray ring 2 is facing upward. An L-shaped through hole 21 that penetrates the spray ring 2 is opened in the middle of the spray ring 2. The inner side wall of the spray ring 2 close to the recovery bin 1 is set with an inclined surface that is inclined toward the side close to the through hole 21 and away from the recovery bin 1. The upper side of the spray ring 2 is fixedly connected and connected to a vertical liquid delivery pipe 22. Figure 2 , Figure 3 and Figure 4 A circle of liquid outlet holes 23 are provided on one inclined side of the spray ring 2 and are arranged along the edge of the spray ring 2 and communicated with the interior of the spray ring 2, and a pressurizing component 3 for pressurizing the high-pressure liquid is provided in the liquid delivery pipe 22.
[0036] Reference Figure 3 and Figure 4 The pressurizing assembly 3 includes a plurality of spiral blades 31 located in the liquid delivery pipe 22 and evenly distributed along the axial direction of the rotation axis of the liquid delivery pipe 22. A truncated cone-shaped pressurizing cylinder 32 located on the side of the blades 31 close to the spray ring 2 is fixedly connected to the liquid delivery pipe 22, and the diameter of the pressurizing cylinder 32 gradually decreases toward the side close to the spray ring 2. The liquid delivery pipe 22 is provided with a guide fan 33 located on the side of the blades 31 away from the pressurizing cylinder 32 and driving the passivation liquid in the liquid delivery pipe 22 to move toward the spray ring 2. The liquid delivery pipe 22 is provided with a rotating assembly 4 for driving the guide fan 33 to rotate.
[0037] The rotating assembly 4 includes a worm gear 41 sleeved on the outside of the guide fan 33 and fixedly connected to the guide fan 33. The outside of the worm gear 41 passes through the side wall of the liquid delivery pipe 22 and is rotatably connected to the liquid delivery pipe 22. The outside of the liquid delivery pipe 22 is rotatably connected to a worm 42 meshing with the worm gear 41, and one end of the worm gear 42 is mounted with a first motor (not shown in the figure) fixedly connected to the outer wall of the liquid delivery pipe 22.
[0038] The driving angle steel is driven by the rotating roller 131 to move from the feed port 12 to the discharge port 11 and pass through the recovery bin 1. At this time, the end of the angle steel passes through the spray ring 2. The first motor drives the worm 42 to drive the worm gear 41 to rotate. At this time, the guide fan 33 fixed to the worm gear 41 rotates, which is convenient for driving the passivation liquid in the liquid delivery pipe 22 to move toward the spray ring 2. The passivation liquid in the liquid delivery pipe 22 moves to the blade 31. At this time, the spiral blade 31 guides the passivation liquid, so that the passivation liquid spirally moves toward the spray ring 2. The passivation liquid moves in the direction of the spray ring 2. When the spirally moving passivation liquid moves into the pressurizing cylinder 32, the shape of the pressurizing cylinder 32 further pressurizes the passivation liquid, so that the increase in the area of the liquid outlet 23 does not affect the uniform distribution of the passivation liquid on the surface of the angle steel. The pressurized passivation liquid is passed into the spray ring 2, and the passivation liquid inside the spray ring 2 is evenly moved to the surface of the angle steel through the liquid outlet 23, and the excess liquid on the surface of the angle steel moves along the length direction of the angle steel until it falls into the recovery bin 1. At this time, the solution on the surface of the angle steel is evenly distributed, and the angle steel spraying is completed.

[0040] The control assembly 6 includes a driving rod 61 corresponding to the baffle 5 and perpendicular to the corresponding baffle 5. The driving rod 61 is located on the side of the corresponding baffle 5 away from the through hole 21 and is fixedly connected to the middle of the corresponding baffle 5. The end of the driving rod 61 away from the baffle 5 passes through the side wall of the spray ring 2 and is slidably connected to the spray ring 2. The end of the driving rod 61 away from the baffle 5 is sleeved with a first spring 62. One end of the first spring 62 is fixedly connected to the end of the driving rod 61, and the other end is fixedly connected to the outer wall of the spray ring 2. When the first spring 62 is at its original length, the baffle 5 does not block the liquid outlet 23, and a moving part 63 for driving the baffle 5 to block the liquid outlet 23 is provided on the liquid delivery pipe 22.
[0041] Reference Figure 3 and Figure 5 The moving member 63 includes two vertical moving plates 631 arranged on both sides of the spray ring 2 in the length direction, and the ends of the driving rods 61 on both sides of the spray ring 2 in the length direction abut against the corresponding side walls of the moving plates 631. The upper ends of the moving plates 631 are threadedly connected with a horizontal bidirectional lead screw 632 that is rotatably connected to the outer side wall of the liquid delivery pipe 22.
[0042] The ends of the two driving rods 61 at the lower end of the spray ring 2 are fixed to each other and fixedly connected to the same vertical rack 633 .

[0044] The first motor drives the worm 42 to drive the second gear 637 to rotate. At this time, the third gear 635 drives the bidirectional lead screw 632 to rotate under the drive of the second gear 637, so that the movable plate 631 moves in the direction of approaching each other and pushes the driving rods 61 on both sides of the spray ring 2 to drive the corresponding baffle 5 to move in the direction close to the through hole 21. At this time, the first gear 634 rotates with the bidirectional lead screw 632 and drives the driving rod 61 on the lower side of the spray ring 2 through the rack 633 to drive the corresponding baffle 5 to move in the direction close to the through hole 21 until the baffles 5 are spliced with each other and block the liquid outlet 23. At this time, the third gear 635 is driven by the sliding assembly 7 to slide and disengage from the second gear 637, so that the position of the baffle 5 is fixed by the bidirectional lead screw 632, so that the passivation liquid can quickly fill the inside of the spray ring 2.
[0045] When the passivation liquid output by the liquid delivery pipe 22 quickly fills the inside of the spray ring 2, the baffle 5 is driven to move at the same time and open the liquid outlet 23, so that the passivation liquid inside the spray ring 2 moves to the surface of the angle steel through the liquid outlet 23. At this time, liquid is discharged from all parts of the liquid outlet 23 at the same time, reducing the possibility of uneven liquid discharge from all parts of the liquid outlet 23.

The second motor 751, the second hydraulic cylinder 81 and the connecting block 82 are all coaxial with the bidirectional screw 632. A monitoring component for controlling the rotation of the second motor 751 is provided in the spray ring 2.
[0050] The monitoring device includes a first pressure gauge (not shown in the figure) installed on the upper side of the spray ring 2 and connected to the interior of the spray ring 2, and a second pressure gauge (not shown in the figure) installed on the lower side of the spray ring 2 and connected to the interior of the spray ring 2. The first pressure gauge and the second pressure gauge are both radio-connected to the same control host (not shown in the figure), and the control host is radio-connected to the second motor 751.
[0051] The moving plate 631 drives the driving rod 61 to move the baffle 5. At this time, the baffle 5 corresponding to the sliding rod 71 moves and squeezes the inclined surface on the sliding rod 71, thereby driving the sliding rod 71 to move upward. At this time, the upper end of the sliding rod 71 contacts the outer wall of the driving ring 73 and drives the third gear 635 to move along the inclined surface of the outer wall of the driving ring 73 to the side away from the second gear 637. When the baffles 5 are spliced with each other, the third gear 635 and the second gear 637 are completely separated. At this time, the third gear 635 is driven by the first hydraulic cylinder 74 to continue to move and away from the second gear 637, reducing the possibility of the second gear 637 continuing to drive the third gear 635 to continue to rotate.
[0052] The first pressure gauge and the second pressure gauge respectively monitor the pressure on the upper and lower sides of the spray ring 2. When the values monitored by the first pressure gauge and the second pressure gauge are the same, an electrical signal is transmitted to the control host, so that the control host drives the second motor 751 to rotate, and the second hydraulic cylinder 81 drives the connecting block 82 to insert into the bidirectional screw 632. At this time, the second motor 751 drives the bidirectional screw 632 to reverse through the second hydraulic cylinder 81 and the second connecting block 82, and at this time, the telescopic rod of the first hydraulic cylinder 74 contracts, so as to facilitate the driving of the baffle 5 to reset. At this time, the first spring 62 recovers its deformation and pulls the driving rod 61 and the baffle 5 to move away from the through hole 21 and open the liquid outlet 23. At this time, the sliding rod 71 moves downward under the drive of the second spring 72, and the third spring 752 partially recovers its deformation, so as to facilitate the spraying of passivation liquid onto the surface of the angle steel.
[0053] The implementation principle of a spray passivation device for angle steel in an embodiment of the present application is as follows: when the angle steel moves and passes through the recovery bin 1, the end of the angle steel passes through the spray ring 2, and the driving worm gear 41 drives the guide fan 33 to rotate, so as to drive the passivation liquid in the liquid delivery pipe 22 to move in the direction close to the spray ring 2. When the passivation liquid in the liquid delivery pipe 22 moves to the blade 31, the spiral blade 31 guides the passivation liquid and makes the passivation liquid move in a spiral shape into the pressurizing cylinder 32. The shape of the pressurizing cylinder 32 further pressurizes the passivation liquid, and the pressurized passivation liquid is passed into the spray ring 2. The passivation liquid inside the spray ring 2 moves to the surface of the angle steel through the liquid outlet 23, driving the excess liquid on the surface of the angle steel to move along the length direction of the angle steel until it falls into the recovery bin 1. At this time, the solution on the surface of the angle steel is evenly distributed, and the spraying of the angle steel is completed.
[0054] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
