Description

Technical Field

[0001] This invention belongs to the technical field of auxiliary equipment for shipbuilding, and in particular, an integrated forming equipment for pre-processing T-beam panels. Background Technology

[0002] In shipbuilding, T-beams are important structural components, and the quality of their panel pretreatment directly affects the overall performance and service life of the ship. Traditional T-beam panel pretreatment typically requires multiple independent equipment and processes. First, separate rust and paint removal equipment is used, followed by panel straightening and chamfering, requiring continuous transfer.

[0003] This not only results in a large equipment footprint, but also necessitates manual transfer of T-beam panels between different processes, leading to low efficiency and a high risk of panel deformation during manual transfer. Furthermore, the poor coordination among multiple pieces of equipment and processes makes it difficult to guarantee the consistency and stability of pretreatment quality, failing to meet the high-efficiency and high-quality requirements of modern shipbuilding. Summary of the Invention

[0004] This invention provides an integrated molding equipment for pre-processing T-beam panels, which can improve production efficiency, processing accuracy, and enhance the strength of the profiles.

[0005] The present invention solves the above-mentioned technical problems through the following technical solutions: An integrated forming equipment for pre-processing T-beam panels includes a rust removal mechanism, a grinding mechanism, a mechanical straightening mechanism, a chamfering roller, and a frame. A support roller is installed on the frame to support a steel strip. The rust removal mechanism, grinding mechanism, straightening mechanism, and chamfering roller are sequentially arranged on the frame. The chamfering roller is located at the discharge end, and the rust removal mechanism is located at the feed end. The rust removal mechanism includes a rust removal roller and a rotating shaft. The rust removal roller includes a housing, a striking block, and lifting grooves. The inner wall of the housing is provided with 3-5 lifting grooves, which are distributed on the inner wall. The striking block is located inside the housing.

[0006] In the aforementioned integrated molding equipment for pre-processing T-beam panels, the lifting groove is arc-shaped, and both the cross-section and longitudinal section of the lifting groove are arc-shaped.

[0007] The aforementioned integrated forming equipment for pre-processing T-beam panels includes a grinding mechanism comprising a top grinding assembly and an end grinding assembly. The top grinding assembly includes a grinding roller, sandpaper, a cantilever shaft, a first motor, and a position adjustment mechanism. The sandpaper is radially distributed on the outer wall of the grinding roller. The cantilever shaft passes through a shaft hole in the middle of the grinding roller. The position adjustment mechanism includes a linear guide pair, an adjusting block, and an adjusting screw. The cantilever shaft is connected to the drive shaft of the motor. The linear guide pair is fixed to the frame. The linear guide pair and the adjusting screw are horizontally arranged. The motor base is fixed to the adjusting block. The linear guide is fixed to the top of the frame. Both ends of the adjusting block are connected to the sliders of the linear guide pair. An adjusting screw hole is provided in the middle of the adjusting block. One end of the adjusting screw passes through the adjusting screw hole, and the other end of the adjusting screw has a handle. The handle end of the adjusting screw is connected to the frame via a bearing.

[0008] In the aforementioned integrated forming equipment for pre-processing T-beam panels, the end grinding assembly is the same as the top grinding mechanism, and the end grinding assembly is located on both sides of the frame.

[0009] The aforementioned integrated forming equipment for pre-processing T-beam panels also includes an adjustment mechanism. The adjustment mechanism comprises a connecting rod, a support, and a tension spring. The support is located above the support roller. The middle part of the connecting rod is hinged to the support. Both ends of the connecting rod are connected to tension springs. The bottom of the tension springs is connected to the bottom of the frame. The top grinding assembly is fixedly installed on the left end of the connecting rod. A counterweight is also provided. The counterweight has a through hole in its middle. The right end of the connecting rod passes through the through hole of the counterweight.

[0010] The aforementioned integrated molding equipment for pre-processing T-beam panels also includes a dust removal mechanism. This mechanism comprises a suction nozzle, a rotary joint, an air vent, a filter cartridge, a vacuum source, and a dust collection chamber. The suction nozzle is made of rubber and is sheet-shaped, distributed between the sandpaper. The sanding roller is a hollow structure, with a dust collection chamber inside. The sanding roller has suction holes, and the suction nozzle communicates with the dust collection chamber through these holes. Air vents are located on the outer side of the sanding roller, spaced around the shaft hole. Each air vent is connected to one end of the air vent via a rotary joint, and the other end of the air vent is connected to the filter cartridge. The vacuum source provides negative pressure to the filter cartridge.

[0011] The aforementioned integrated forming equipment for pre-processing T-beam panels includes a rotary joint comprising a connecting piece, a steel ball, a sealing bolt, a tubular protrusion, and a concave head. The protrusion is inserted into the concave head, the connecting piece is integrally formed with the concave head, the connecting piece is fixedly connected to the grinding roller, and a vent is surrounded within the concave head. The protrusion is inserted into the concave head, and both the outer wall of the protrusion and the inner wall of the concave head are provided with grooves, which together form a circular slot. The outer wall of the concave head is provided with a through hole, the bottom of which communicates with the groove. The steel ball enters the slot through the through hole and fills the slot. The outer end of the through hole is provided with an internal thread, and the sealing bolt is screwed into the through hole, with the bottom of the sealing bolt abutting against the steel ball.

[0012] The aforementioned T-beam panel pretreatment integrated molding equipment is also equipped with a sealing ring. The drawing head is provided with two sealing grooves, which are respectively located on both sides of the groove, and the sealing ring is stuck in the sealing groove.

[0013] The aforementioned integrated forming equipment for pre-processing T-beam panels includes a straightening mechanism comprising two straightening rollers arranged in pairs between the chamfering roller and the end grinding assembly. The chamfering roller comprises two sets of pressure rollers symmetrically arranged vertically. Each set of pressure rollers comprises two rotating rollers symmetrically arranged front and rear. A chamfering mechanism is provided on the outer side of the rotating rollers. The chamfering mechanism is an annular metal layer and is higher than the rotating rollers. The lateral spacing of the chamfering mechanism of each set of pressure rollers is slightly smaller than the width of the panel, and the longitudinal spacing of the upper and lower pressure rollers matches the height of the panel. Compared with existing technologies, this invention integrates various processes, enabling continuous operation of rust removal, grinding, and straightening, thereby improving production efficiency, processing accuracy, and profile strength. It reduces labor costs, allowing one person to complete the pretreatment of the entire T-beam panel, instead of the previous multi-site, multi-person work. It also improves welding strength by using this device to remove paint, grind, and clean the joint between the panel and web, saving time. Furthermore, it reduces the number of transfers, integrating several processes into a single machine, increasing production efficiency by over 80%. Attached Figure Description

Detailed Implementation

[0016] The specific embodiments of the present invention will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate the present invention.

[0017] like Figures 1 to 8 As shown, the present invention includes a rust removal mechanism 1, a grinding mechanism 2, a chamfering roller 3, and a frame 4. A support roller 5 is mounted on the frame 4 to support the steel strip. The rust removal mechanism 1, grinding mechanism 2, and chamfering roller 3 are sequentially arranged on the frame 4, with the chamfering roller 3 located at the discharge end and the rust removal mechanism 1 located at the feed end. The rust removal mechanism 1 includes a rust removal roller and a rotating shaft. The rust removal roller includes a housing 6, a striking block 7, and lifting grooves 8. The inner wall of the housing 6 has 3-5 lifting grooves 8 distributed on the inner wall. The striking block 7 is located inside the housing 6. (Refer to...) Figure 6 The rotating shaft is connected to one side of the housing 6, ensuring that the striking block 7 strikes the housing 6 directly. The striking block 7 is preferably spherical. The panel moves on the support roller 5, and the chamfering roller 3 drives the panel to move. The striking block 7 moves upward with the lifting groove 8, reaching its highest point. The striking block 7 then falls out of the lifting groove 8 and strikes the housing 6, generating vibration that loosens or removes the rust in the center of the panel. The center of the panel is then polished by the transmission grinding mechanism 2. Finally, the chamfering roller 3 chamfers both sides of the panel. To facilitate the smooth fall of the striking block 7, the lifting groove 8 is arc-shaped, with both its cross-section and longitudinal section being arc-shaped. This allows the striking block 7 to converge and fall towards the center. It also causes the housing 6 to vibrate, thus striking the panel. This knocking away the rust in the center of the panel facilitates better polishing, improving the quality of polishing and ultimately enhancing the welding quality.

[0018] In order to polish the center and sides of the panel, the polishing mechanism 2 includes a top polishing assembly 9 and an end polishing assembly 10. The top polishing assembly 9 includes a polishing roller 11, polishing sandpaper 12, a cantilever shaft 13, a first motor 14, and a position adjustment mechanism 15. The polishing roller 11 of the top polishing assembly 9 is arranged parallel to the panel. The sandpaper 12 is radially distributed on the outer wall of the sanding roller 11. The cantilever shaft 13 passes through the shaft hole in the middle of the sanding roller 11. The position adjustment mechanism 15 includes a linear guide pair 16, an adjustment block 17, and an adjustment screw 18. The cantilever shaft 13 is connected to the drive shaft of the motor 14. The linear guide pair 16 is fixed on the frame 4. The linear guide pair 16 and the adjustment screw 18 are horizontally arranged. The base of the motor 14 is fixed to the adjustment block 17. The linear guide is fixed to the top of the frame 4. Both ends of the adjustment block 17 are connected to the slider of the linear guide pair 16. The middle of the adjustment block 17 is provided with an adjustment screw hole. One end of the adjustment screw 18 passes through the adjustment screw hole. The other end of the adjustment screw 18 is provided with a handle 19. The handle 19 end of the adjustment screw 18 is connected to the frame 4 through a bearing. By rotating the adjusting screw 18, the cantilever shaft 13 can be moved along the linear guide pair 16, adjusting the position of the grinding roller 11 in the direction of the linear guide pair 16, so that the grinding roller 11 can grind the center line of the panel. The end grinding assembly 10 is located on both sides of the support roller 5 and fixed on the frame 4. The grinding roller 11 of the end grinding assembly 10 is set perpendicular to the panel to grind the side edges of the panel. The end grinding assembly 10 has the same structure as the top grinding assembly 9, and can clean and grind the top surface and both sides of the panel at the same time, increasing the strength of the subsequent welding of the T-beam panel and the web plate, and reducing the problems of complicated process connection, time-consuming transfer, and low production efficiency.

[0019] To increase the contact area between the top grinding mechanism of the end grinding assembly 10 and the panel, an adjustment mechanism is provided. This adjustment mechanism includes a connecting rod 20, a support 21, and a tension spring 22. The support 21 is positioned above the support roller 5. The middle of the connecting rod 20 is hinged to the support 21, and both ends of the connecting rod 20 are connected to the tension spring 22. The bottom of the tension spring 22 is connected to the bottom of the frame 4. The top grinding assembly 9 is fixedly installed on the left end of the connecting rod 20. A counterweight 23 is also provided, with a through hole in its middle. The right end of the connecting rod 20 passes through the through hole of the counterweight 23. By adjusting the position of the counterweight 23 on the right side of the connecting rod 20, the left end of the connecting rod 20 can be raised or lowered, adjusting the height of the top grinding mechanism and thus adjusting the vertical position of the top grinding assembly 9 relative to the panel.

[0020] To reduce dust during the polishing process, a dust removal mechanism is provided, which includes a suction nozzle 24, a rotary joint, an air vent 26, a filter cartridge 27, a vacuum source 28, and a dust collection chamber 29. The suction nozzle 24 is made of rubber and is sheet-shaped, distributed between the sandpapers 12. The polishing roller 11 is a hollow structure, with the dust collection chamber 29 inside. The polishing roller 11 has suction holes, and the suction nozzle 24 communicates with the dust collection chamber 29 through the suction holes. The outer side of the polishing roller 11 has air vents 30, which are spaced around the shaft hole of the polishing roller 11. The air vents 30 are connected to one end of the air vent 26 through the rotary joint, and the other end of the air vent 26 is connected to the filter cartridge 27. The vacuum source 28 provides negative pressure to the filter cartridge 27. The length of the nozzle 24 is slightly less than the length of the sandpaper. During the sanding process of the sandpaper 12, the nozzle 24 can suck the sanding debris into the dust collection chamber 29 and enter the filter cartridge 27 through the air pipe 26.

[0021] To ensure that the air vent 26 remains stationary while the grinding roller 11 rotates, the rotary joint includes a connecting piece 32, a steel ball 33, a sealing bolt 34, a tubular protrusion 35, and a concave head 36. One end of the protrusion 35 is inserted into the concave head 36, and the other end is connected to the air vent 26. The connecting piece 32 is integrally formed with the concave head 36 and is fixedly connected to the grinding roller 11. The air vent 30 is surrounded by the concave head 36. The protrusion 35 is inserted into the concave head 36. The outer wall of the protrusion 35 and the inner wall of the concave head 36 are both provided with grooves, which together form a circular slot 37. The outer wall of the concave head 36 is provided with a through hole, and the bottom of the through hole is connected to the groove. The steel ball 33 enters the slot 37 through the through hole and fills the slot 37. The outer end of the through hole is provided with an internal thread. The sealing bolt 34 is screwed into the through hole, and the bottom of the sealing bolt 34 abuts against the steel ball 33. The steel ball 33 inside the slot 37 can stably fit the protruding head 35 and the concave head 36 together. To ensure airtightness, a sealing ring 38 is provided. The protruding head 35 has two sealing grooves, which are respectively located on both sides of the recess. The sealing ring 38 is fitted into the sealing groove. This ensures that the protruding head remains stationary while the recess rotates. By matching the protruding head and the recess, the air passage can be kept unobstructed and stable while the grinding roller rotates, thus enabling dust removal.

[0022] The straightening mechanism includes two straightening rollers 39, which are arranged in pairs between the chamfering roller 3 and the end grinding assembly 10. The chamfering roller 3 includes two sets of pressure rollers arranged symmetrically at the top and bottom. Each set of pressure rollers includes two rotating rollers 40 arranged symmetrically at the front and back. A chamfering mechanism 41 is provided on the outer side of the rotating roller 40. The chamfering mechanism 41 is an annular metal layer and is higher than the rotating roller 40. The lateral spacing of the chamfering mechanisms 41 in each set of pressure rollers is slightly smaller than the width of the panel, and the longitudinal spacing between the upper and lower pressure rollers matches the height of the panel. This facilitates the conveying of the panel and allows for chamfering of the sidewalls of the panel during conveying.

[0023] The working process is as follows: Adjusting the position of the tension spring 22 and the counterweight 23 on the right side of the connecting rod 20 can adjust the contact area between the grinding roller 11 of the top grinding assembly 9 and the panel. Then, the position adjustment mechanism 15 can align the grinding roller 11 of the top grinding mechanism with the center line of the panel, while simultaneously bringing the grinding roller 11 of the end grinding mechanism into contact with the side edge of the panel. Then, the striking block 7 strikes the housing 6 to remove rust from the center line of the panel. Then, the grinding mechanism 2 polishes the center line of the panel after rust removal. Finally, the straightening roller 39 adjusts the orientation of the panel to facilitate the chamfering mechanism 41 chamfering the side edges of the panel, completing the processing operation.

[0024] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
