Description

Technical Field

[0001] The invention relates to the technical field of profile feeding, in particular to a profile feeding device for producing corrugated steel plates. Background Art

[0002] Corrugated steel sheet, also known as profiled steel, is a metal material with a specific shape and size, strength and rigidity. The shape of profiled steel is classified according to different uses. H-shaped steel is a steel material with a cross-sectional shape similar to the English letter "H". It is named for its unique cross-sectional design. H-shaped steel has excellent mechanical properties and a wide range of applications. It is an important material in modern construction and industrial fields. It is named because it uses welding technology to make the cross-section into an H shape. It is divided into submerged arc welding H-shaped steel and high-frequency welding H-shaped steel. The processes used for submerged arc welding H-shaped steel are divided into: steel plate - automatic striping - assembly - automatic submerged arc welding - flaw detection - flange correction - web correction - end surface processing - sandblasting and rust removal - painting. The fully automatic submerged arc welding production line is controlled by a microcomputer from feeding, assembly, and welding to ensure the dimensional accuracy of the produced H-shaped steel and the quality of the welds meet national standards. At present, when feeding corrugated steel sheets, the steel sections need to be transported to the designated processing position. The existing steel section feeding device is usually composed of a plurality of rollers distributed in parallel. However, due to the special shape of the steel sections, the contact area between the rollers of the existing feeding device and the steel sections is small, which may easily lead to poor feeding stability and smoothness. In addition, a lot of welding slag is likely to remain on the surface of the steel section after welding, which needs to be cleaned manually. Due to the large volume of the profiles, the manual cleaning method is not only inefficient but also time-consuming and labor-intensive. Therefore, we propose a profile feeding device for corrugated steel sheet production. Summary of the invention

[0014] Compared with the prior art, the present invention has the following beneficial effects: The present invention contacts the steel section through two driving rollers, and the rotation of the driving rollers can greatly increase the contact area with the steel section during the feeding process.

[0015] The present invention can apply pressure to the movable plate through the reciprocating motion of the cam. At the same time, the elasticity of the spring acts on the resetting of the movable plate. This design enables the movable plate to smoothly move up and down after being acted upon by the force. The reciprocating motion of the movable plate will continuously strike the bottom of the steel section, and this continuous striking will generate vibration, which helps to effectively separate the welding slag on the steel section from the steel itself. The separated welding slag is more easily absorbed and cleaned by the dust hood. This process avoids the welding slag from adhering to the surface of the steel section, thereby affecting the cleaning effect.

When the positioning plate is separated from the steel section, the meshing transmission effect between the toothed plate a and the spur gear a is utilized to make the guide roller contact the steel section, thereby reaching a centered position when feeding the steel section, preventing the steel section from deviating from its position when feeding the steel section, and avoiding the situation where the welding process accuracy of the steel section is affected by displacement during feeding the steel section, and can significantly improve the stability of the steel section when feeding.

DETAILED DESCRIPTION

[0019] 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.

[0020] Example 1: Please refer to Figure 1 - Fig.12 , a profile feeding device for producing corrugated steel sheets shown in the figure comprises a frame 1, on which a plurality of rollers 2 equidistantly distributed are rotatably connected, and also comprises a mounting frame 3 fixed on the frame 1, a profile steel positioning unit 4 is arranged on the frame 1, and the profile steel positioning unit 4 is used for welding and auxiliary guiding positioning during profile steel processing, and a support frame 5 arranged on the frame 1, and a conveying mechanism 6 matched with the profile steel is arranged on the support frame 5, and the conveying mechanism 6 is used for conveying the profile steel, and a frame 7 fixed on the frame 1, a welding slag cleaning unit 8 matched with the profile steel is arranged on the frame 7, and the welding slag cleaning unit 8 is used for cleaning welding slag on the surface of the profile steel; Among them, a plurality of rollers 66 are fixed on the frame 1 and are distributed at equal distances. The distance between the plurality of rollers 66 is smaller than the distance between the plurality of rollers 2. With the arrangement of the rollers 66, the stability of the profile steel during feeding and movement can be further improved, and the feeding stability effect of the profile steel after processing is significantly improved. In addition, a driving device for driving the plurality of rollers 2 to rotate is provided on the frame 1, and the plurality of rollers 2 are driven by the driving device, so that the plurality of rollers 2 are synchronously rotated in the same direction after being subjected to force. In addition, the main structure of the driving device includes: a motor and a plurality of pulleys and belts, so as to realize precise control of synchronously driving the plurality of rollers 2 to rotate in the same direction, which is a conventional setting in the art, so it will not be described in detail here; In this solution, the conveying mechanism 6 and the driving device cooperate to convey the steel sections in the same direction, and the conveying mechanism 6 can contact the bottom surface of the steel sections and achieve the purpose of transmission and conveying, which can solve the problem of unstable feeding due to the special shape of the steel sections in the existing feeding method. After the steel sections are conveyed to the appropriate position, the steel section positioning unit 4 clamps and positions the steel sections. When the welding is completed and the feeding and conveying needs to be continued, the steel section positioning unit 4 continues to provide guidance for the steel section during transportation to prevent the steel section from deviation during transportation and feeding. The welding slag cleaning unit 8 cleans the welding slag and impurities on the surface of the steel section after the welding process, and then the roller 2 conveys the steel section to the next process.

[0021] Further as Figure 1 , Figure 2 , Figure 4 , Figure 6 and Fig.10 As shown, it is worth specifically explaining that the conveying mechanism 6 includes a rotating seat 22 fixed on the support frame 5, and two driving rollers 23 are rotatably connected to the rotating seat 22, a driving motor b24 is fixed on the support frame 5, and a large gear 25 is tightly sleeved on the output shaft of the driving motor b24, and a small gear 26 meshing with the large gear 25 is fixed on the driving roller 23; Among them, a rubber protective sleeve 67 is fixed on the outer surface of the driving roller 23. The additional rubber anti-slip sleeve can significantly improve the friction between the driving roller 23 and the steel section during contact, thereby effectively improving the stability of the steel section during transportation. The driving roller 23 and the central transverse line of the roller 2 are arranged on the same horizontal plane. With the position setting of the driving roller 23 and the roller 2, the bumping phenomenon caused by the steel section during feeding and movement can be avoided. The two driving rollers 23 are in contact with the steel section, and the rotation of the driving rollers 23 can greatly increase the contact area with the steel section during the feeding process, which can effectively prevent the unsmooth feeding of the steel section, and ensure that the driving rollers 23 can maintain good contact with the bottom surface of the steel section during the transportation and feeding of the steel section, thereby greatly improving the stability of the steel section during feeding. Accordingly, this improvement solves the problem of poor feeding stability caused by insufficient contact area. It should be noted that, by driving the driving motor b24, the large gear 25 follows its output shaft to rotate synchronously, and the meshing transmission effect of the large gear 25 and the small gear 26 is utilized to drive the driving roller 23 to rotate, and the driving roller 23 is in contact with the bottom surface of the steel section to generate friction. The friction between the driving roller 23 and the bottom surface of the steel section can be utilized to ensure that the steel section can be transported and moved in a stable manner. This method effectively avoids unnecessary shaking of the steel section during feeding due to insufficient contact area during the transportation process.

[0022] Embodiment 2: Based on Embodiment 1, according to Figure 1 , Figure 2 , Figure 3 and Fig.10 As shown, it is worth to explain in detail that the welding slag cleaning unit 8 includes a dust suction pump 27 fixed on the frame 7, and a connecting pipe 29 is fixed on the frame 7 through a mounting frame 28, the input end of the dust suction pump 27 is connected to the connecting pipe 29 through a pipeline 30, two dust suction covers 31 are arranged on the frame 7, and the dust suction covers 31 are connected to the connecting pipe 29 through a soft pipe 32, and the supporting frame 51 is fixed to the soft pipe 32 through a mounting sleeve 60, and the mounting sleeve 60 is added to ensure the stability of the soft pipe 32 when extracting waste chips, and prevent the soft pipe 32 from shaking; It should be noted that, through the continuous operation of the dust suction pump 27, the two dust suction hoods 31 are used to effectively absorb the welding slag and residual waste chips on the surface of the steel section. This method can reduce the labor intensity of manual cleaning by the staff to a greater extent. In this way, not only can the work efficiency of cleaning the welding slag and waste chips of the steel section be greatly improved, but also the time required for cleaning the waste chips on the steel section can be greatly shortened, thereby bringing a more time-saving and labor-saving cleaning experience to the staff.

[0023] Specifically, refer to Figure 2 , Figure 3 , Figure 6 , Figure 8 - Fig.12As shown, the frame 7 is provided with a reciprocating knocking mechanism 33 matched with the welding slag cleaning unit 8, the reciprocating knocking mechanism 33 includes a driving shaft 34 rotatably connected to the frame 1, a servo motor b35 coaxially fixed to the driving shaft 34 is fixed on the frame 1, two cams 36 are rotatably connected to the driving shaft 34, and a movable plate 37 abutting against the two cams 36 is slidably connected to the frame 1, two guide blocks 57 are fixed to the movable plate 37, and a guide groove 58 for slidingly connecting the guide blocks 57 is opened on the frame 1, and the guide groove 58 is used to slide the guide blocks 57. The block 57 slides in the guide groove 58, which can not only guide the movable plate 37, but also ensure the stability of the movable plate 37 when moving. A squeezing plate 59 in contact with the cam 36 is fixed to one side wall of the movable plate 37. The additional squeezing plate 59 can ensure the smoothness of the squeezing transmission between the cam 36 and the movable plate 37, and the squeezing plate 59 is arranged on a side wall close to the cam 36 in an arc surface. The opening length of the guide groove 58 is consistent with the length of the cam 36. A spring is fixed on the frame 1 through the mounting block 38. 39, the other end of the spring 39 is fixed to the movable plate 37, the frame 7 is rotatably connected with a driven shaft 40, a pulley a41 is fixed between the driven shaft 40 and the driving shaft 34, and the two pulleys a41 are connected by a belt a42, a rotating wheel 43 is fixed to the driven shaft 40, a rotating rod b44 is rotatably connected to the frame 7, and a fan-shaped gear 45 is fastened and sleeved on the rotating rod b44, and a groove 61 is opened on the carrier 51, and the opening length of the groove 61 is greater than the rotation diameter length of the fan-shaped gear 45, and the fan-shaped gear 45 and the rotating wheel are connected. A connecting rod 46 is hinged between the frame 7 and the frame 7, a rotating shaft 47 is rotatably connected, a spur gear b48 meshing with the sector gear 45 is fixed on the rotating shaft 47, and a spur gear c49 is coaxially fixed on the rotating shaft 47, a bearing frame 51 is slidably connected to the frame 7 through a plurality of mounting sleeves 50, and the bearing frame 51 is meshingly connected with the spur gear c49 through a rack 52, and the dust hood 31 is fixed to the bearing frame 51 through two connecting rods 68, and the additional connection rods 68 can significantly improve the stability of the dust hood 31 when in use; It should be noted that, through the reciprocating motion of the cam 36, pressure can be applied to the movable plate 37. At the same time, the elasticity of the spring 39 acts on the reset of the movable plate 37. This design enables the movable plate 37 to smoothly move up and down after being acted upon by the force. The reciprocating motion of the movable plate 37 will continuously strike the bottom of the steel section. This continuous striking will generate vibration, which helps to effectively separate the welding slag on the steel section from the steel itself. The separated welding slag is more easily absorbed and cleaned by the dust hood 31. This process avoids the welding slag from adhering to the surface of the steel section, thereby affecting the cleaning effect. It should also be noted that, through the ingenious cooperation of the rotating wheel 43 and the connecting rod 46, the sector gear 45 can be driven to perform precise reciprocating swings along the axis of the rotating rod b44. This reciprocating swinging motion is transmitted through the meshing of the sector gear 45 and the spur gear b48, thereby realizing the reciprocating rotation of the rotating shaft 47 in the counterclockwise and clockwise directions. The coordinated work of this series of actions enables the carrier 51 to reciprocate left and right, thereby driving the dust hood 31 to move synchronously. This design enables the dust hood 31 to cover the top of the steel section more comprehensively, effectively absorb and clean up the waste chips, thereby greatly improving the cleaning effect of the welding slag on the top of the steel section, and ensuring the efficiency and thoroughness of the cleaning work; The working principle of the reciprocating hammering mechanism 33 for hammering the bottom of the steel section and driving the carrier frame 51 to move back and forth is as follows: first, the driving shaft 34 is driven by the servo motor b35 to rotate synchronously, driving the cam 36 to rotate synchronously, and utilizing the elastic effect of the spring 39 to ensure that the movable plate 37 is always in contact with the cam 36. When the movable plate 37 is squeezed by the cam 36, it moves up and down, so that the reciprocating plate hammers the bottom of the steel section back and forth, so that the welding slag is separated from the surface of the steel section after the shock, and the driven shaft 40 is rotated synchronously by utilizing the transmission effect of the pulley and the belt. The rotating wheel 43 is driven to rotate synchronously, and the transmission effect of the connecting rod 46 is utilized to make the sector gear 45 reciprocate along the axis of the rotating rod b44 after being subjected to force. The sector gear 45 and the spur gear b48 are meshed and transmitted to make the rotating shaft 47 realize intermittent reciprocating motion, thereby driving the spur gear c49 to operate synchronously. The meshing transmission effect between the spur gear c49 and the rack 52 is utilized to achieve the reciprocating left and right movement of the support frame 51 after being subjected to force, and then the dust hood 31 is driven to move synchronously, so that the dust hood 31 can reciprocate left and right above the steel section, greatly increasing the effect of absorbing welding slag and waste chips.

[0024] Example 3: Reference Figure 1 , Figure 2 , Figure 3 , Figure 5 , Figure 6 and Fig.10 As shown, this embodiment further illustrates other embodiments, and the difference lies in the optimization of the center position when the steel is fed and the stability during welding; Furthermore, the steel positioning unit 4 includes a bidirectional screw rod 9 rotatably connected to the mounting frame 3, and a servo motor a10 coaxially fixed to the bidirectional screw rod 9 is fixed on the frame 1, a wire sleeve 11 threadedly connected to the bidirectional screw rod 9 is slidably connected to the mounting frame 3, two guide bars 64 are fixed to the mounting frame 3, and a guide groove 65 slidably connected to the guide bar 64 is provided on the wire sleeve 11, and the matching arrangement of the guide groove 65 and the guide bar 64 can guide the wire sleeve 11, thereby ensuring that the wire sleeve 11 can always move in a straight line, and a positioning plate 12 is fixed on the wire sleeve 11, a reinforcing plate 62 is fixed between the positioning plate 12 and the wire sleeve 11, and the reinforcing plate 62 is arranged obliquely to the wire sleeve 11, thereby ensuring that the positioning plate 12 is used for clamping and positioning the steel. Strength, the frame 1 is rotatably connected with a rotating rod a13, a spur gear a14 is fixed on the rotating rod a13, and a mounting frame 15 is fixed on the positioning plate 12, and a rubber pad 63 is fixed on the positioning plate 12. With the addition of the rubber pad 63, not only can the pre-tightening effect be achieved when clamping the steel section, but also the positioning effect of the steel section can be completed more tightly. The spur gear a14 is meshed with two staggered toothed plates a16, one of which is fixed to the mounting frame 15, and a bracket 17 is fixed on the other toothed plate a16. The bracket 17 is rotatably connected with a guide roller 18, and a driving motor a20 is fixed on the bracket 17 through a support plate 19, and two meshing bevel gears 21 are provided between the driving motor a20 and the guide roller 18; Among them, a support plate 53 is fixed on the frame 1, and a support block 54 is fixed on the support plate 53 to allow the toothed plate a16 to be slidably connected. By sliding one of the toothed plates a16 in the support block 54, it can guide the toothed plate a16 and effectively improve the stability of the toothed plate a16 when moving. Two guide rods 55 that slide through the support plate 53 are fixed on the bracket 17, and one end of the two guide rods 55 is jointly fixed with a limit plate 56. The setting of the guide rods 55 plays a role in stabilizing the bracket 17 when it moves under force, and prevents the bracket 17 from shaking when it moves; It should be noted that, through the threaded transmission between the screw rod and the thread sleeve 11, the two positioning plates 12 clamp and position the steel, so that the steel is clamped and positioned when it is welded, preventing displacement during the welding process of the steel, thereby improving the accuracy of the steel welding process and preventing the steel from shaking; It should also be noted that when the positioning plate 12 is separated from the steel section, the meshing transmission effect between the toothed plate a16 and the spur gear a14 is utilized to make the guide roller 18 contact the steel section, so as to reach a state of being centered when feeding the steel section, thereby preventing the steel section from being deviated when feeding the steel section, and avoiding the situation in which the welding processing accuracy of the steel section is affected by the displacement when feeding the steel section, which can significantly improve the stability of the steel section when feeding the steel section; In this scheme, when feeding and conveying the steel sections, it has the following working principles: First, the driving motor b24 drives the large gear 25 to rotate synchronously, and the meshing transmission between the large gear 25 and the small gear 26 causes the driving roller 23 to rotate synchronously. The driving roller 23 is in contact and friction with the bottom of the steel section, thereby driving the steel section to be transported. The driving device drives multiple rollers 2 to rotate, thereby realizing stable transportation of the steel section for feeding; Secondly, when welding the steel, stop feeding the steel, drive the servo motor a10 to make the bidirectional screw 9 rotate synchronously, and use the threaded transmission effect between the bidirectional screw 9 and the thread sleeve 11 to make the thread sleeve 11 move linearly along the installation frame 3 after being stressed, and then drive the positioning plate 12 to move synchronously until the positioning plate 12 contacts the steel, thereby completing the clamping and positioning state of the steel. When the positioning of the steel needs to be released, the thread sleeve 11 moves away from the steel, driving the toothed plate a16 Synchronous movement, using the meshing transmission effect between the toothed plate a16 and the spur gear a14, the other toothed plate a16 is forced to move towards the direction close to the steel section, and then drives the guide roller 18 to move synchronously until the guide roller 18 comes into contact with the steel section. The guide roller 18 is driven by the drive motor a20 and cooperates with the meshing transmission effect between the two bevel gears 21 to rotate after being forced, which can not only assist the feeding of the steel section, but also ensure that the steel section is kept in the center position for conveying and feeding; Then, the reciprocating knocking mechanism 33 drives the movable plate 37 to knock back and forth toward the bottom of the steel section, so as to separate the welding slag and waste chips on the steel section and facilitate the cleaning of the waste chips. At the same time, the carrier frame 51 can be driven to move back and forth left and right, and then the dust cover 31 can be driven to move back and forth left and right synchronously. Finally, driven by the dust suction pump 27, the waste chips on the top of the steel section are sucked through the input end of the dust suction pump 27, and through the dust suction hood 31, the soft pipe 32, the connecting pipe 29 and the pipeline 30, thereby achieving the purpose of cleaning the waste chips on the top of the steel section.

[0025] The servo motor a10, the drive motor a20, the drive motor b24, the dust suction pump 27 and the servo motor b35 can all be purchased from the market and equipped with a separate power supply. They are mature technologies in this field and have been fully disclosed, so they will not be repeated in the specification.
