This invention proposes a straightening pretreatment mechanism for steel plate processing. Summary of the Invention

[0005] The purpose of this invention is to solve the problem in the prior art where, when using a steel plate straightening machine for straightening pretreatment of steel, in order to avoid the adhesion of protruding debris caused by external environmental factors on the surface of the steel plate, resulting in an uneven surface, the uneven debris is squeezed against the steel plate during operation, leading to an uneven surface on the steel plate. Therefore, a straightening pretreatment mechanism for steel plate processing is proposed.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a straightening pretreatment mechanism for steel plate processing, comprising: a straightening machine, wherein a conveyor frame is installed at one end of the straightening machine, a drive shaft is installed inside the conveyor frame, and a drive assembly is provided on one side surface of the conveyor frame corresponding to the position of the drive shaft, the drive assembly including a housing, a drive motor, a sprocket, and a chain; an extrusion device, wherein the extrusion device is located on both end side walls of the conveyor frame, the extrusion device including an extrusion assembly and a guide assembly; an adjustment device, wherein the adjustment device is located on the inner wall of the conveyor frame corresponding to the position of the steel plate body; and an auxiliary device, wherein the auxiliary device is located inside the conveyor frame corresponding to the position of the adjustment device.

[0007] By adopting the above technical solution, in order to avoid the adhesion of protruding hard lumps on the surface of the steel plate body during the pre-treatment of straightening steel using a steel plate straightening machine, and to prevent the steel plate body from becoming uneven when it is transported into the steel plate straightening machine for operation, the extrusion device, adjustment device and auxiliary device installed on the conveyor frame are used to operate, thereby facilitating and effectively cleaning the entire surface of the steel plate body, which is beneficial to the straightening treatment of the steel plate body.

[0008] Preferably, the extrusion assembly includes two connecting frames, which are respectively fixedly connected to the two end side walls of the conveyor frame. The inner wall of the connecting frame is in communication with the side wall of the conveyor frame. A fixing frame is fixedly connected to the surface of each connecting frame. A servo electric cylinder is fixedly connected to the inner wall of each fixing frame. An extrusion block is fixedly connected to the output end of the servo electric cylinder. The cross-section of the extrusion block is U-shaped. The side of the two extrusion blocks that is close to each other abuts against the steel plate body.

[0009] By adopting the above technical solution, during the cleaning process of the steel plate body, it is necessary to use an extrusion device to extrude and limit the position of the steel plate body on the entire conveyor frame, so as to prevent the drive shaft on the conveyor frame from causing the steel plate body to shift. At this time, the servo electric cylinders installed at both ends of the conveyor frame drive the extrusion block in the connecting frame through the output end of the servo electric cylinder, so that the extrusion block with a "U" shaped cross section extrudes and fixes the steel plate body, thereby conveniently and effectively limiting and fixing the position of the entire steel plate body.

[0010] Preferably, a plurality of first springs are fixedly connected to both sides of the inner wall of the extrusion block, and an extrusion column is fixedly connected to the upper end of each of the plurality of first springs, wherein the extrusion columns are all rubber columns.

[0011] By adopting this preferred solution, the first spring and the extrusion column set on the inner walls of both sides of the extrusion block increase the friction and extrusion of the entire steel plate body by the extrusion force generated by the first spring and the rubber extrusion column, which facilitates better positioning of the steel plate body.

[0012] Preferably, the guiding assembly includes two fixed frames, one end of each fixed frame is fixedly connected to the inner walls of both sides of the conveying frame, a rotating frame is rotatably connected to the inner wall of each fixed frame, rollers are rotatably connected to both ends of each rotating frame, and a coil spring is sleeved on the inner wall of each fixed frame, with both ends of the coil spring fixedly connected to the rotating frame and the fixed frame respectively.

[0013] By adopting this preferred solution, in the process of conveying the steel plate body on the drive shaft on the inner wall of the conveyor frame, in order to avoid the steel plate body shifting position during movement and thus colliding and getting stuck with the inner wall of the conveyor frame, a guiding component is used for guidance and protection. The torsional force generated by the coil spring on the fixed frame drives the position of the rotating frame to be fixed, thereby allowing the rotating roller on the rotating frame to slide and guide and limit the side wall of the steel plate body.

[0014] Preferably, the adjusting device includes two positioning frames, which are fixedly connected to the two side surfaces of the conveyor frame respectively. The positions of the positioning frames correspond to the positions of the servo cylinders. A servo motor is fixedly connected to one side surface of the conveyor frame corresponding to the position of the positioning frame. A gear is fixedly connected to the output end of the servo motor. A positioning frame is fixedly connected to the surface of the positioning frame. A rack is slidably connected to the inner wall of the positioning frame. The tooth surface of the rack meshes with the tooth surface of the gear. Each surface of the positioning frame has a sliding groove. A sliding rod is slidably connected to the inner wall of each sliding groove. One end of one of the sliding rods is fixedly connected to the rack. Positioning plates are fixedly connected to the arc surfaces of both sliding rods. A screw is fixedly connected to the bottom end of each of the two positioning plates. A positioning post is slidably passed through the arc surface of each screw. The same tool holder is fixedly connected to the end of each positioning post that is close to each other. An extrusion shaft is threaded through the arc surface of the screw on both sides of the positioning post.

[0015] By adopting the above technical solution, after the entire steel plate body is squeezed and limited by the extrusion devices installed at both ends of the conveyor frame, in order to facilitate the cleaning of the surface of the steel plate body, the servo motor on the conveyor frame drives the rack on the positioning frame through the gear at the output end of the servo motor. The rack drives the slide to move along the slide groove opened on the positioning frame, thereby allowing the positioning plate on the slide rod to drive the knife holder to cut and scrape the surface of the steel plate body. The screw on the bottom end of the positioning plate, the extrusion shaft and the positioning column on the knife holder are mutually squeezed and fixed, which facilitates the positioning and replacement of the entire knife holder.

[0016] Preferably, a protective gasket is abutted on the side of the extrusion shaft near the positioning post, and the surface of the protective gasket slides through the screw.

[0017] By adopting this preferred solution, when the positioning column is squeezed and limited by the extrusion shaft, the protective pad can effectively squeeze, fix and limit the positioning column and the entire tool holder.

[0018] Preferably, the bottom surface of the tool holder abuts against the surface of the steel plate body, and the tool holder is a cemented carbide holder.

[0019] By adopting this preferred solution, a tool holder made of cemented carbide is used to prevent deformation of the entire tool holder during long-term operation.

[0020] Preferably, the auxiliary device includes two limiting plates, which are respectively fixedly connected to a positioning plate. Limiting blocks are inserted into the surfaces of both limiting plates. The cross-section of each limiting block is U-shaped. A common connecting plate is fixedly connected to the side of each limiting block that is close to the other. Limiting posts slide through both ends of the surface of the connecting plate. A cleaning plate is fixedly connected to the bottom end of each of the two limiting posts. A second spring is fitted onto the arc surface of each limiting post. The two ends of the second spring are fixedly connected to the limiting post and the cleaning plate, respectively. A moving rod slides through the surface of each limiting block. The arc surface of the moving rod slides through the surface of the limiting plate. A third spring is fitted onto the arc surface of the moving rod. The two ends of the third spring are fixedly connected to the moving rod and the limiting block, respectively.

[0021] By adopting the above technical solution, after the surface of the entire steel plate body is cut and scraped by the blade holder in the adjustment device, in order to better clean the surface of the steel plate body, the limiting plate on the positioning plate abuts against the limiting blocks on both ends of the connecting plate, and the tension generated by the second spring of the upper limit column on the connecting plate is used to squeeze the position of the cleaning plate, which facilitates better cleaning of the steel plate body. The position of the moving rod on the limiting block can be adjusted, replaced and fixed by the tension generated by the third spring.

[0022] Preferably, the bottom end of the movable rod is fixedly connected to an insert block, and the insert block has a pointed conical cross-section.

[0023] By adopting this preferred solution, when using the moving rod to connect and limit the position with the limiting plate and the limiting block, the pointed cone-shaped insert on the moving rod can be used for better operation and use.

[0024] Preferably, a plurality of cleaning columns are fixedly connected to the bottom surface of the cleaning plate, and all of the cleaning columns are nylon columns.

[0025] This preferred solution utilizes nylon cleaning columns, which allow for better cleaning of the surface of the steel plate.

[0026] Compared with the prior art, the advantages and positive effects of the present invention are as follows:

[0027] 1. In this invention, when using a steel plate straightening machine to perform straightening pretreatment on steel, in order to avoid the adhesion of protruding hard lumps on the surface of the steel plate body, when the steel plate body is transported into the steel plate straightening machine for operation, unevenness occurs on the steel plate body. At this time, the extrusion device, adjustment device and auxiliary device installed on the conveyor frame are used to operate, thereby facilitating and effectively cleaning the surface of the entire steel plate body, which is beneficial to the straightening treatment of the steel plate body.

[0028] 2. In this invention, by setting up an extrusion device, during the cleaning process of the steel plate body, it is necessary to use the extrusion device to extrude and limit the position of the steel plate body on the entire conveyor frame to prevent the transmission shaft on the conveyor frame from causing the steel plate body to shift. At this time, the servo electric cylinders installed at both ends of the conveyor frame drive the extrusion block in the connecting frame through the output end of the servo electric cylinder, so that the extrusion block with a "U" shaped cross section extrudes and fixes the steel plate body, thereby conveniently and effectively limiting and fixing the position of the entire steel plate body. Through the first spring and extrusion column set on both sides of the extrusion block, the extrusion force generated by the first spring and the rubber extrusion column increase the friction and extrusion of the entire steel plate body, which facilitates better limiting of the steel plate body. During the process of conveying the steel plate body on the transmission shaft on the inner wall of the conveyor frame, in order to prevent the steel plate body from shifting its position during movement and thus colliding and stopping with the inner wall of the conveyor frame, a guide component is used for guidance and protection. The torsional force generated by the coil spring on the fixed frame drives the fixed position of the rotating frame, thereby allowing the rotating roller on the rotating frame to slide and guide and limit the side wall of the steel plate body.

[0029] 3. In this invention, by setting an adjustment device, after the entire steel plate body is squeezed and limited by the extrusion devices installed at both ends of the conveyor frame, in order to facilitate the cleaning of the surface of the steel plate body, the servo motor on the conveyor frame drives the rack on the positioning frame through the gear at the output end of the servo motor. The rack moves along the slide groove opened on the positioning frame, so that the positioning plate on the slide rod drives the tool holder to cut and scrape the surface of the steel plate body. The screw on the bottom end of the positioning plate, the extrusion shaft and the positioning post on the tool holder are mutually squeezed and fixed, which facilitates the replacement and limiting of the entire tool holder. When the extrusion shaft is used to squeeze and limit the positioning post, the protective gasket can effectively squeeze, fix and limit the positioning post and the entire tool holder. When the tool holder is used for long-term operation, in order to avoid deformation of the entire tool holder, a tool holder made of hard alloy material is used.

[0030] 4. In this invention, by setting an auxiliary device, after the surface of the entire steel plate body is cut and scraped by the blade holder in the adjusting device, in order to better clean the surface of the steel plate body, the limiting plate on the positioning plate abuts against the limiting blocks on both ends of the connecting plate. Then, the tension generated by the second spring of the upper limit column on the connecting plate is used to squeeze the position of the cleaning plate, which facilitates better cleaning of the steel plate body. The moving rod inserted on the limiting block can be stretched and limited by the tension generated by the third spring to prevent the moving rod from falling off. When the moving rod is inserted and limited by the limiting plate and the limiting block, the pointed cone-shaped insert on the moving rod can be used for better operation. The cleaning column made of nylon material can be used to better clean the surface of the steel plate body. Attached Figure Description

However, the invention may also be practiced in other ways than those described herein, and therefore the invention is not limited to the specific embodiments disclosed in the following specification.

[0044] Example 1, such as Figure 1-10 As shown, the present invention provides a straightening pretreatment mechanism for steel plate processing, including a straightening machine 1, a conveyor frame 3 installed at one end of the straightening machine 1, a drive shaft 5 installed inside the conveyor frame 3, and a drive assembly 4 disposed on one side surface of the conveyor frame 3 corresponding to the position of the drive shaft 5. The drive assembly 4 includes a housing, a drive motor, a sprocket, and a chain; an extrusion device 6 located on the side walls at both ends of the conveyor frame 3, the extrusion device 6 including an extrusion component 61 and a guide component 62; an adjustment device 7 located on the inner wall of the conveyor frame 3 corresponding to the position of the steel plate body 2; and an auxiliary device 8 located inside the conveyor frame 3 corresponding to the position of the adjustment device 7.

[0045] The following section will describe in detail the specific configuration and function of its extrusion device 6, adjustment device 7, and auxiliary device 8.

[0046] like Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, the extrusion assembly 61 includes two connecting frames 611, which are fixedly connected to the side walls of both ends of the conveyor frame 3. The inner walls of the connecting frames 611 are connected to the side walls of the conveyor frame 3. Fixed frames 613 are fixedly connected to the surface of each connecting frame 611. Servo electric cylinders 612 are fixedly connected to the inner walls of each fixed frame 613. Extrusion blocks 614 are fixedly connected to the output ends of the servo electric cylinders 612. The cross-section of the extrusion blocks 614 is U-shaped. The side of the two extrusion blocks 614 that is close to each other abuts against the steel plate body 2. Both sides of the inner walls of the extrusion blocks 614 are fixedly connected to the steel plate body 2. A plurality of first springs 615 are fixedly connected, and each of the first springs 615 is fixedly connected to an extrusion column 616. The extrusion columns 616 are all rubber columns. The guide assembly 62 includes two fixed frames 621. One end of each fixed frame 621 is fixedly connected to the inner walls of both sides of the conveyor frame 3. A rotating frame 622 is rotatably connected to the inner wall of each fixed frame 621. Rollers 624 are rotatably connected to both ends of each rotating frame 622. A coil spring 623 is sleeved on the inner wall of each fixed frame 621. The two ends of the coil spring 623 are fixedly connected to the rotating frame 622 and the fixed frame 621, respectively.

[0047] The effect achieved by the entire extrusion device 6 is that the output end of the servo electric cylinder 612 installed at both ends of the conveyor frame 3 drives the extrusion block 614 in the connecting frame 611, so that the extrusion block 614 with a "U" shaped cross section extrudes and fixes the steel plate body 2, thereby conveniently and effectively limiting and fixing the position of the entire steel plate body 2.

[0048] like Figure 3 , Figure 4 , Figure 7 , Figure 8 and Figure 9As shown, the adjusting device 7 includes two positioning frames 703, which are fixedly connected to the two side surfaces of the conveyor frame 3 respectively. The positions of the positioning frames 703 correspond to the positions of the servo cylinder 612. A servo motor 701 is fixedly connected to one side surface of the conveyor frame 3 corresponding to the position of the positioning frame 703. A gear 702 is fixedly connected to the output end of the servo motor 701. A positioning frame 705 is fixedly connected to the surface of the positioning frame 703. A rack 704 is slidably connected to the inner wall of the positioning frame 705. The tooth surface of the rack 704 meshes with the tooth surface of the gear 702. Each surface of the positioning frame 703 has a sliding groove 713. A slide rod 706 is slidably connected to the inner wall of each sliding groove 713. One of the slide rods 706... One end of 06 is fixedly connected to the rack 704. The arc surfaces of the two slide rods 706 are fixedly connected to the positioning plates 707. The bottom ends of the two positioning plates 707 are fixedly connected to the screws 710. The arc surfaces of the screws 710 slide through the positioning pins 709. The ends of the two positioning pins 709 that are close to each other are fixedly connected to the same tool holder 708. The arc surfaces of the screws 710 are threaded through the positions on both sides of the positioning pins 709. The side of the extrusion pins 711 that is close to the positioning pins 709 is abutted by a protective pad 712. The surface of the protective pad 712 slides through the screws 710. The bottom surface of the tool holder 708 abuts against the surface of the steel plate body 2. The tool holder 708 is a hard alloy frame.

[0049] The effect of the entire adjustment device 7 is that the gear 702 at the output end of the servo motor 701 drives the rack 704 on the positioning frame 703, and the rack 704 drives the slide to move along the slide groove 713 opened on the positioning frame 703, so that the positioning plate 707 on the slide rod 706 drives the knife holder 708 to cut and scrape the protruding debris on the surface of the steel plate body 2 caused by external environmental factors.

[0050] like Figure 10As shown, the auxiliary device 8 includes two limiting plates 81, which are fixedly connected to the positioning plate 707. Limiting blocks 82 are inserted into the surfaces of both limiting plates 81. The cross-section of each limiting block 82 is U-shaped. A common connecting plate 83 is fixedly connected to the side of the two limiting blocks 82 that is close to each other. Limiting posts 85 slide through both ends of the surface of the connecting plate 83. A common cleaning plate 84 is fixedly connected to the bottom ends of the two limiting posts 85. A second spring 86 is fitted onto the arc surface of each limiting post 85. Both ends of the device are fixedly connected to the limiting post 85 and the cleaning plate 84, respectively. A moving rod 87 slides through the surface of the limiting block 82. The arc surface of the moving rod 87 slides through the surface of the limiting plate 81. A third spring 88 is sleeved on the arc surface of the moving rod 87. Both ends of the third spring 88 are fixedly connected to the moving rod 87 and the limiting block 82, respectively. An insert 89 is fixedly connected to the bottom end of the moving rod 87. The cross-section of the insert 89 is conical. Several cleaning posts are fixedly connected to the bottom surface of the cleaning plate 84. All of the cleaning posts are nylon posts.

[0051] The effect achieved by the entire auxiliary device 8 is that the limiting plate 81 on the positioning plate 707 abuts against the limiting blocks 82 at both ends of the connecting plate 83, and the tension generated by the second spring 86 of the upper limit post 85 on the connecting plate 83 is used to squeeze the position of the cleaning plate 84, which facilitates better cleaning of the steel plate body 2. The moving rod 87 inserted on the limiting block 82 can be stretched and limited by the tension generated by the third spring 88 to prevent the moving rod 87 from falling off.

[0052] Example 2, based on Example 1,

[0053] The overall working principle is as follows: when the steel plate straightening machine 1 is used to straighten the steel, in order to avoid the surface of the steel plate body 2 from being attached with protruding hard blocks, when the steel plate body 2 is transported into the steel plate straightening machine 1 for operation, the steel plate body 2 becomes uneven. At this time, the extrusion device 6, adjustment device 7 and auxiliary device 8 installed on the conveyor frame 3 are used to operate, so as to conveniently and effectively clean the surface of the entire steel plate body 2, which is conducive to the straightening treatment of the steel plate body 2.

[0054] During the cleaning process of the steel plate body 2, the extrusion device 6 is used to extrude and limit the position of the steel plate body 2 on the entire conveyor frame 3 to prevent the drive shaft 5 on the conveyor frame 3 from causing the steel plate body 2 to shift. At this time, the servo electric cylinders 612 installed at both ends of the conveyor frame 3 drive the extrusion block 614 in the connecting frame 611 through the output end of the servo electric cylinder 612. The extrusion block 614 with a "U" shaped cross section extrudes and fixes the steel plate body 2, thereby conveniently and effectively limiting and fixing the position of the entire steel plate body 2. The first spring 615 and the extrusion column 616 set on the inner walls on both sides of the extrusion block 614 allow the first spring to... The extrusion force generated by the spring 615 and the rubber extrusion column 616 increase the friction and extrusion of the entire steel plate body 2, which facilitates better positioning of the steel plate body 2. During the process of conveying the steel plate body 2 on the transmission shaft 5 on the inner wall of the conveyor frame 3, in order to prevent the steel plate body 2 from shifting its position during movement and thus colliding and getting stuck with the inner wall of the conveyor frame 3, the guide component 62 is used for guidance and protection. The torsional force generated by the coil spring 623 on the fixed frame 621 drives the fixed position of the rotating frame 622, thereby allowing the rotating roller 624 on the rotating frame 622 to slide and guide and limit the steel plate body 2.

[0055] After the entire steel plate body 2 is compressed and limited by the extrusion devices 6 installed at both ends of the conveyor frame 3, in order to facilitate the cleaning of the surface of the steel plate body 2, the servo motor 701 on the conveyor frame 3 drives the rack 704 on the positioning frame 703 via the gear 702 at the output end of the servo motor 701. The rack 704 then moves along the slide groove 713 opened on the positioning frame 703, thereby causing the positioning plate 707 on the slide rod 706 to drive the knife holder 708 to cut and scrape the surface of the steel plate body 2. The screw 710 at the bottom, the extrusion shaft 711, and the positioning post 709 on the tool holder 708 are mutually extruded and fixed, which facilitates the positioning and replacement of the entire tool holder 708. When the extrusion shaft 711 is used to extrude and limit the positioning post 709, the protective gasket 712 can effectively extrude, fix and limit the positioning post 709 and the entire tool holder 708. When the tool holder 708 is used for a long time, in order to avoid deformation of the entire tool holder 708, a tool holder 708 made of cemented carbide is used.

[0056] After the surface of the entire steel plate body 2 is cut and scraped by the knife holder 708 in the adjusting device 7, in order to better clean the surface of the steel plate body 2, the limiting plate 81 on the positioning plate 707 abuts against the limiting blocks 82 at both ends of the connecting plate 83. Then, the tension generated by the second spring 86 of the upper limit post 85 of the connecting plate 83 is used to squeeze the position of the cleaning plate 84, which facilitates better cleaning of the steel plate body 2. The moving rod 87 inserted on the limiting block 82 can be stretched and limited by the tension generated by the third spring 88 to prevent the moving rod 87 from falling off. When the moving rod 87 is inserted and limited by the limiting plate 81 and the limiting block 82, the pointed conical insert 89 on the moving rod 87 can be used for better operation. The cleaning column made of nylon material can be used to better clean the surface of the steel plate body 2.

Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields.
