Description

Technical Field

[0001] The present invention relates to the technical field of color steel plate processing, and particularly to a forming and processing machine for the production of heat-insulating color steel plates. Background Art

[0002] Heat-insulating color steel plates are usually made by adhering heat-insulating materials to color steel tiles. In the production process of color steel tiles, it is a crucial step to use a forming and processing machine to perform forming processing on the color steel plates.

[0003] On the existing forming and processing machines, the structure for roll-pressing and shaping the corrugations is sleeved on the roller shaft assembly. However, the roller shaft assembly is mostly an integrated design and cannot be directly disassembled separately. This requires a large-scale disassembly of the forming and processing machine and the removal of the entire roller shaft assembly from the forming and processing machine in order to extract and disassemble the roll-pressing and shaping structure from the roller shaft assembly for maintenance or replacement. Such an operation is rather troublesome and inconvenient, greatly reducing the disassembly efficiency of the roll-pressing and shaping structure. Summary of the Invention

[0004] In view of this, the present invention provides a forming and processing machine for the production of heat-insulating color steel plates to solve the problem of low disassembly efficiency of the roll-pressing and shaping structure.

[0005] The technical solution proposed by the present invention is: a forming and processing machine for the production of heat-insulating color steel plates, specifically including a roller shaft assembly, which is jointly composed of a short hollow roller shaft, a long hollow roller shaft, and a short hollow connecting shaft detachably connected between the two; On the end plates at both ends of the short hollow connecting shaft, two hexagonal insertion posts are symmetrically and slidably installed in a spring-pushing manner; on the opposite ends of the short hollow roller shaft and the long hollow roller shaft, plug covers are integrally formed. The two hexagonal insertion posts are inserted and matched with the two plug covers in a penetrating manner; a rotary driving shaft is rotatably installed through the peripheral wall of the short hollow connecting shaft. At the bottom end of the rotary driving shaft, two L-shaped swing rods are symmetrically welded. Between the two L-shaped swing rods and the two hexagonal insertion posts, two connecting rods are symmetrically rotatably connected; on the peripheral walls of the short hollow roller shaft and the long hollow roller shaft, symmetrically arranged T-shaped limit members are slidably installed through the spring-pushing manner. The protruding part at the front end of the T-shaped limit member is in an isosceles trapezoid structure; inside the short hollow roller shaft and the long hollow roller shaft, hexagonal driving shafts are slidably installed through the spring-pushing manner. On the hexagonal driving shafts, symmetrically arranged L-shaped insertion rods are welded. The L-shaped insertion rods are inserted and matched with the T-shaped limit members in a penetrating manner. The opposite ends of the two hexagonal driving shafts are in abutting contact with the opposite ends of the two hexagonal insertion posts.

[0006] Further, the roller shaft assemblies are arranged in pairs, one above the other and corresponding to each other. On the upper and lower roller shaft assemblies, a plurality of roller pressing rings and shaping rings are slidably sleeved at equal intervals respectively. At both ends of the inner holes of the roller pressing rings and the shaping rings, annular inclined sections are provided.

[0007] Furthermore, retaining rings are fixedly sleeved on the short hollow roller shaft and the long hollow roller shaft at positions near the two roller pressing rings on the outer side. The roller pressing ring is located between the retaining ring on the corresponding side and the two T-shaped limit members adjacent to the retaining ring. Each roller pressing ring located between the two outer roller pressing rings is located between the four T-shaped limit members adjacent to it.

[0008] Furthermore, retaining rings are fixedly sleeved on the short hollow roller shaft and the long hollow roller shaft at positions near the two shaping rings on the outer side. The shaping ring is located between the retaining ring on the corresponding side and the two T-shaped limit members adjacent to the retaining ring. Each shaping ring located between the two outer shaping rings is located between the four T-shaped limit members adjacent to it.

[0009] Furthermore, one hypotenuse of the protruding part at the front end of the T-shaped limit member near an annular inclined section abuts against the annular inclined section.

[0010] Furthermore, at least two spaced bushings are welded at the inner center positions of the short hollow roller shaft and the long hollow roller shaft. The hexagonal drive shaft is in sliding fit with the bushings through penetration. A retaining ring is welded and sleeved on the hexagonal drive shaft. A spring for pushing the hexagonal drive shaft is sleeved on the hexagonal drive shaft and is compressed and clamped between the retaining ring and the bushing.

[0011] Furthermore, three horizontally arranged positioning shafts are welded between the end plugs at both ends of the short hollow connecting shaft. Three sliding ears are welded around the opposite ends of the two hexagonal insertion posts. The sliding ears are in sliding fit with the horizontally arranged positioning shafts. A spring for pushing the hexagonal insertion post is sleeved on the upper horizontally arranged positioning shaft and is compressed and clamped between the two sliding ears that are in sliding fit with the same horizontally arranged positioning shaft on the upper side. Two limiting rings are symmetrically welded and sleeved on the two end portions of the lower horizontally arranged positioning shaft. When the two hexagonal insertion posts slide towards each other, the two lower sliding ears respectively abut against the two limiting rings.

[0012] Furthermore, assembly grooves are formed at the opposite ends of the two hexagonal insertion posts. A hinge shaft is fixedly connected in the assembly groove. The front end of the connecting rod is hinged to the front end portion of the L-shaped swing rod, and its bottom end is hinged to the hinge shaft.

[0013] Furthermore, symmetrically arranged vertical guide shafts are welded on the inner circumferences of the short hollow roller shaft and the long hollow roller shaft. The horizontal part of the T-shaped limit member is in sliding fit with the two vertical guide shafts at the corresponding positions. A spring for pushing the T-shaped limit member is sleeved on the vertical guide shaft and is compressed and clamped between the horizontal parts of the two T-shaped limit members arranged symmetrically up and down. Symmetrically arranged T-shaped positioning plates are welded to the inner circumferences of the short hollow roller shaft and the long hollow roller shaft. The T-shaped limiting member is located between two adjacent T-shaped positioning plates, and the horizontal rod section of the L-shaped insertion rod is inserted through and cooperates with the horizontal part of the T-shaped limiting member and these two T-shaped positioning plates.

[0014] The forming and processing machine for the production of heat-insulating color steel plates provided by the present invention has the following beneficial effects: First, the roller pressing ring and the shaping ring together form a roller pressing and shaping mechanism. In the present invention, the roller shaft assembly is composed of a short hollow roller shaft, a long hollow roller shaft, and a detachable short hollow connecting shaft. Only by separately disassembling and removing the short hollow connecting shaft can the roller pressing ring or the shaping ring sleeved on the roller shaft assembly be directly extracted and disassembled for maintenance or replacement. Compared with the prior art in which the roller shaft assembly is integrally integrated, it can save the trouble of greatly disassembling the forming and processing machine and removing the roller shaft assembly as a whole from the forming and processing machine to extract and disassemble the roller pressing and shaping mechanism, which helps to simplify the disassembly steps of the roller pressing and shaping mechanism and improve its disassembly efficiency.

[0015] Second, through the power transmission of two hexagonal drive shafts and in conjunction with the reverse pushing effect of two springs thereon, when the two hexagonal insertion posts are driven to slide towards or away from each other and perform assembly locking and loosening unlocking on the short hollow connecting shaft, the L-shaped insertion rods on the two hexagonal drive shafts can be driven to slide away from each other, realizing automatic locking and unlocking of the T-shaped limiting member. This can save the trouble of manually performing the unlocking and locking operations of the roller pressing ring and the shaping ring, which helps to further simplify the disassembly and assembly steps of the roller pressing and shaping mechanism and improve its disassembly and assembly efficiency.

[0016] Third, during the process of sliding and sleeving the roller pressing ring and the shaping ring, when the roller pressing ring or the shaping ring slides past the T-shaped limiting member and is placed between the T-shaped limiting member and the retaining ring or between two adjacent T-shaped limiting members, the T-shaped limiting member in the unlocked state can be kept protruding outward by the reverse pushing of the above-mentioned spring to implement the use state of blocking and limiting the roller pressing ring or the shaping ring, preventing the roller pressing ring or the shaping ring from sliding and shifting under the action of various vibration stresses during the assembly process and being unable to accurately maintain the installation position where it is statically fixed in the axial direction of the roller shaft assembly. And when the T-shaped limiting member in the unlocked state is kept in this state by reverse pushing, it can wait for the L-shaped insertion rod to be inserted and cooperate with it in the subsequent process, which helps to ensure the normal and effective implementation of the automatic locking function of the T-shaped limiting member.

[0036] It is worth noting that: in the field of mechanical design, the power device uses a chain and a mechanical load for transmission, which is common knowledge and existing technology. Therefore, the specific transmission structure between the chain and the roller shaft assembly, the setting form of the transmission structure and the transmission principle are not explained in the specification; the model selection of the automation controller, intermediate relay, contactor, photoelectric switch 20, the connection and wiring method between them and the control principle are existing technologies for personnel in this field engaged in equipment electrical automation transformation, design, testing and maintenance, so they are not elaborated in the description.

[0037] The following is a detailed explanation and description of the specific details, implementation steps, functions and interrelationships of the above contents, as well as the role they play in the implementation of this technical solution: The rolling ring 6 and the molding ring 7 together constitute a rolling molding mechanism. In the present invention, the rolling shaft assembly is composed of a short hollow roller shaft 3, a long hollow roller shaft 4 and a detachable short hollow connecting shaft 5. Only the short hollow connecting shaft 5 needs to be disassembled and removed separately to directly extract and disassemble the rolling ring 6 or the molding ring 7 mounted on the rolling shaft assembly for repair or replacement. Compared with the existing technology of integrating the rolling shaft assembly into one, this can save the trouble of disassembling the molding machine on a large scale and removing the rolling shaft assembly as a whole from the molding machine before extracting and disassembling the rolling molding mechanism. It helps to simplify the disassembly steps of the rolling molding mechanism and improve its disassembly efficiency.

[0038] When the two hexagonal plug posts 502 are respectively inserted and mated with the end caps of the short hollow roller shaft 3 and the long hollow roller shaft 4, the short hollow connecting shaft 5 can be positioned between the short hollow roller shaft 3 and the long hollow roller shaft 4, so that the three are stably spliced together to form a complete roller press shaft assembly, and the short hollow connecting shaft 5, the short hollow roller shaft 3 and the long hollow roller shaft 4 are drivingly connected; the two connecting rods 504, the two hexagonal plug posts 502, the two L-shaped swing rods 503 and the torsion drive shaft 501 are jointly connected to form a double crank-slider mechanism. Through this mechanism, twisting the torsion drive shaft 501 can drive the two hexagonal plug posts 502 to slide towards each other and separate from the two end caps, loosen the short hollow connecting shaft 5 and remove the short hollow connecting shaft 5; when the short hollow connecting shaft 5 is spliced and installed, it is necessary to twist the torsion drive shaft 501 to drive the two hexagonal plug posts 502 to slide towards each other and contract inside the short hollow connecting shaft 5 to prevent the two hexagonal plug posts 502 from blocking and interfering with the placement of the short hollow connecting shaft 5 between the short hollow roller shaft 3 and the long hollow roller shaft 4. When the two hexagonal plug posts 502 slide towards each other, the springs on the two horizontally arranged positioning shafts 505 on the upper side are compressed through the sliding ears 5021 on the upper side. In this case, when the torsion drive shaft 501 is loosened, the two springs can automatically push back to drive the two hexagonal plug posts 502 to slide away from each other and be inserted and mated with the two end caps to complete the assembly and positioning of the short hollow connecting shaft 5; when the L-shaped plug rod 901 is inserted and mated with the T-shaped limiting member 8, the T-shaped limiting member 8 can be positioned in a use state where the first end protrudes from the peripheral wall of the roller press shaft assembly. When the T-shaped limiting member 8 is in this state, the protruding part of its first end can block and limit the roller pressing ring 6 or the shaping ring 7, position the roller pressing ring 6 or the shaping ring 7 on the roller press shaft assembly, and prevent the roller pressing ring 6 and the shaping ring 7 from sliding and shifting axially along the roller press shaft assembly, which helps to ensure the stability and accuracy of the roller pressing and shaping functions of the roller pressing ring 6 and the shaping ring 7.

[0039] When the two hexagonal insertion columns 502 slide towards each other to assemble and position the short hollow connecting shaft 5, the opposite ends of the two hexagonal insertion columns 502 respectively abut against the opposite ends of the two hexagonal drive shafts 9, and can push the two hexagonal drive shafts 9 to slide synchronously away from each other. When the two hexagonal drive shafts 9 are pushed to slide away from each other, the L-shaped insertion rods 901 on them can be driven to penetrate and cooperate with the T-shaped limit member 8, completing the positioning and holding of the T-shaped limit member 8. And in the above process, the two hexagonal drive shafts 9 compress the springs on them through the retaining rings 902 on them; when the two hexagonal insertion columns 502 slide towards each other to release and unlock the short hollow connecting shaft 5, they are separated from the two hexagonal drive shafts 9. At this time, the springs on the two hexagonal drive shafts 9 lose the indirect compression and holding force from the two hexagonal insertion columns 502, and can automatically push the two hexagonal drive shafts 9 and the L-shaped insertion rods 901 on them to slide away from each other synchronously, and control the L-shaped insertion rods 901 to be withdrawn from the T-shaped limit member 8, implementing the release and unlocking of the T-shaped limit member 8; before and after the insertion and extraction disassembly of the roller pressing ring 6 or the shaping ring 7, it is necessary to lock and unlock the T-shaped limit member 8. Unlocking the T-shaped limit member 8 can make the T-shaped limit member 8 return to the free-sliding use state, which can ensure that when the roller pressing ring 6 or the shaping ring 7 is extracted and disassembled, the T-shaped limit member 8 can be driven by the roller pressing ring 6 or the shaping ring 7 to slide inward and shrink and hide inside the roller shaft assembly, removing the blocking and limiting effect of the protruding part at the head end of the T-shaped limit member 8 on the roller pressing ring 6 and the shaping ring 7, ensuring that the roller pressing ring 6 and the shaping ring 7 can be normally extracted and disassembled.

[0040] Through the power transmission of the two hexagonal drive shafts 9 and used in conjunction with the reverse push effect of the two springs on them, when the two hexagonal insertion columns 502 are driven to slide towards each other or away from each other to assemble, lock, release and unlock the short hollow connecting shaft 5, they can also push the L-shaped insertion rods 901 on the two hexagonal drive shafts 9 to slide away from each other, realizing the automatic locking and unlocking of the T-shaped limit member 8. This can save the trouble of manually performing the unlocking and locking operations of the roller pressing ring 6 and the shaping ring 7, helping to further simplify the disassembly and assembly steps of the roller pressing and shaping mechanism and improve its disassembly and assembly efficiency.

[0041] Through the guiding effect of the inclined plane of the protruding part at the head end of the T-shaped limiting member 8 and the annular inclined section 19, when the T-shaped limiting member 8 is unlocked and the roller pressing ring 6 and the shaping ring 7 are inserted and removed, the roller pressing ring 6 or the shaping ring 7 can push the T-shaped limiting member 8 to slide inward and contract into the roller pressing shaft assembly, leaving a space for the roller pressing ring 6 or the shaping ring 7 to slide through the T-shaped limiting member 8, releasing the blocking and limiting effect of the T-shaped limiting member 8 on the roller pressing ring 6 and the shaping ring 7, ensuring the normal insertion and removal of the roller pressing ring 6 and the shaping ring 7. When the T-shaped limiting member 8 is driven to slide inward and vacate, the spring on the vertical guide shaft 14 is compressed; during the process of sliding and sleeving the roller pressing ring 6 and the shaping ring 7, when the roller pressing ring 6 or the shaping ring 7 slides through the T-shaped limiting member 8 and is placed between the T-shaped limiting member 8 and the retaining ring 12 or between two adjacent T-shaped limiting members 8, the unlocked T-shaped limiting member 8 can be pushed back to protrude outward by the above spring and be in a state of blocking and limiting the roller pressing ring 6 or the shaping ring 7, avoiding the sliding and displacement of the roller pressing ring 6 or the shaping ring 7 under the action of various vibration stresses during the assembly process and being unable to accurately maintain the installation position where it is stationary and fixed in the axial direction of the roller pressing shaft assembly. And when the unlocked T-shaped limiting member 8 is pushed back and maintained in this state, it can wait for the L-shaped insertion rod 901 to be inserted and matched with it in the subsequent process, which helps to ensure the normal and effective implementation of the automatic locking function of the T-shaped limiting member 8.

[0042] Working principle of this embodiment: During use, the color steel plate for manufacturing color steel tiles is conveyed into the forming machine through the input end of the forming machine by using the pre-conveying equipment. After the color steel plate is conveyed into the forming machine, it successively passes through multiple roller pressing rings 6 and shaping rings 7 driven by synchronous reverse rotation on a row of roller pressing shaft assemblies and rolls and conveys towards the output end of the forming machine. Each roller pressing ring 6 and each shaping ring 7 are arranged in an up-and-down corresponding manner, and a trapezoidal cavity 17 is formed between each roller pressing ring 6 and each shaping ring 7. Through these numerous trapezoidal cavities 17, when the color steel plate is conveyed towards the output end, multiple trapezoidal corrugations can be extruded and formed on it, and finally it is processed into a color steel tile. After the color steel tile is formed, it is conveyed to the post-cutting equipment through the output end for segmented cutting.

[0043] During the use and processing, when the continuous conveyance of the color steel plate stops and no color steel plate passes through the profiling machine equipment for a long time, the photoelectric switch 20 can detect that no color steel plate passes through within the set time range through the rays it emits. At this time, the automation controller can determine that the continuous conveyance of the color steel plate has temporarily stopped based on the detection signal of the photoelectric switch 20 for the above working conditions, and cut off the power supply of the contactor through the intermediate relay, temporarily turn off the motor and the drive assembly 11, and release the continuous rotational drive of the drive assembly 11 on the upper and lower rows of roller shaft pressing assemblies, so that the profiling machine shuts down as a whole to save energy. When another color steel plate is conveyed to the output end of the profiling machine, the color steel plate blocks and triggers the photoelectric switch 20, and the photoelectric switch 20 transmits the trigger signal to the automation controller. The automation controller can determine that the continuous conveyance of the color steel plate has resumed based on this signal, and turn on the power supply of the contactor through the intermediate relay, restart the drive assembly 11, resume the continuous rotational drive on the upper and lower rows of roller shaft pressing assemblies, turn on the profiling machine, and continue to process and manufacture color steel tiles.

[0044] The automation controller, the intermediate relay, the contactor, and the photoelectric switch 20 together form an intelligent control system. Through this system, the profiling machine can adaptively start and stop according to whether a color steel plate is continuously conveyed to the profiling machine in the previous conveying process. This can prevent the profiling machine from continuously running in an idle state, helping to reduce the energy consumption of the profiling machine and improve its energy efficiency ratio.
