Description

Technical Field

[0001] This utility model relates to the field of roll forming machine technology, specifically to a roll forming machine for wall panels of box-type houses. Background Technology

[0002] In today's ever-evolving construction industry, container houses are rapidly emerging as a highly innovative and practical building form. With their significant advantages such as rapid assembly, high mobility, and environmental friendliness and energy efficiency, they demonstrate enormous application potential in numerous fields, including temporary housing on construction sites, emergency rescue housing, and temporary commercial shops. The widespread application of container houses has led to a dramatic increase in demand for wall panels, one of their key components. The quality and production efficiency of these wall panels directly affect the overall quality and market competitiveness of container houses.

[0003] In the actual use of roll forming machines for building wall panels, there is a problem that the height of the rollers on both sides cannot be guaranteed to be completely consistent. This leads to uneven stress on the wall panel during the rolling process, affecting the flatness and dimensional accuracy of the wall panel, and thus reducing the quality of the wall panel. This problem, to some extent, limits the application effect of roll forming technology in the production of prefabricated housing wall panels. Utility Model Content

[0037] The working principle and beneficial effects of this utility model are as follows:

[0038] In this invention, to address the problem that roll forming machines for wall panels in box-type houses cannot guarantee perfectly consistent heights on both sides, a roll forming machine for wall panels in box-type houses is designed, comprising a main body. The first and second pressure rollers are connected to the main body at both ends via high-precision bearings, allowing for smooth rotation. A connecting rod, made of high-strength alloy steel, is connected at both ends to the first and second pressure rollers.

After locking the position, the sliding frame is slid so that the first abutment part slides along the connecting rod. When the sliding rod slides to the other end of the connecting rod, it is checked whether there is a gap between the first abutment part and the connecting rod. If there is a gap, the second telescopic component is activated to keep the connecting rod horizontal. Then the wall panel is placed between the first and second pressure rollers and the main body of the device to perform the roll forming operation on the wall panel. Attached Figure Description

[0052] Reference Figures 1-6This is the first embodiment of the present invention, which proposes a roll forming machine for wall panels of box-type houses. With the direction of wall panel travel as the transverse direction, it includes a device body 1; a first pressure roller 2 is rotatably and vertically slidably disposed on one side of the device body 1; a second pressure roller 3 is rotatably and vertically slidably disposed on the other side of the device body 1; a connecting rod 4 is connected at both ends to the first pressure roller 2 and the second pressure roller 3 respectively; a first mounting frame 5 is disposed on the device body 1; a sliding frame 6 is longitudinally slidably disposed on the first mounting frame 5, and the sliding frame 6 has a plurality of mounting plates 601 on the side near the connecting rod 4, the plurality of mounting plates 601 forming an installation space; a sliding rod 8 is vertically slidably disposed at one end in the installation space, and the other end of the sliding rod 8 has a first abutment part 801; a first telescopic member 9 is disposed at one end on the sliding frame 6, and after the first telescopic member 9 is retracted, the extended end of the first telescopic member 9 approaches the connecting rod 4, and the extended end of the first telescopic member 9 pushes the connecting rod 4 towards the first abutment part 801.

[0053] In this embodiment, to address the problem in related technologies where roll forming machines for wall panels used in box-type houses cannot guarantee perfectly consistent heights on both sides, a roll forming machine for wall panels used in box-type houses is designed. The machine includes a main body 1 assembled through precise welding and bolt connections to ensure it will not deform or wobble during long-term use. The first roller 2 and the second roller 3 are connected to the main body 1 at both ends via high-precision bearings, allowing for smooth rotation of the rollers. A connecting rod 4, made of high-strength alloy steel, is connected at both ends to the first roller 2 and the second roller 3. A first mounting frame 5 is securely fixed to the main body 1 via welding or bolt connections, and its surface undergoes fine processing to ensure the smooth sliding of the sliding frame 6. The sliding frame 6 is made of aluminum alloy, possessing light weight and good wear resistance. The sliding frame 6 achieves smooth sliding on the first mounting frame 5 through a specific sliding structure. A mounting plate 601 is integrally formed with the sliding frame 6, creating an installation space with precise dimensions and shape to ensure the installation accuracy of the sliding rod 8. The surface of the sliding rod 8 is chrome-plated to improve its wear resistance and rust prevention. One end of the sliding rod 8 can slide vertically within the installation space. The first telescopic component 9 can be a hydraulic cylinder or an electric push rod. One end of it is fixed to the sliding frame 6 by a flange or bolts, and the extended end contacts the connecting rod 4 through a contact block to transmit thrust.

[0054] In the actual wall panel roll forming process, the vertical positions of the first pressure roller 2 and the second pressure roller 3 are first adjusted according to the thickness of the wall panel and the process requirements. In order to avoid the first pressure roller 2 and the second pressure roller 3 being inconsistent in height, the first abutting part 801 of the sliding rod 8 is abutted with the connecting rod 4, and then the position of the sliding rod 8 is locked. After locking the position, the sliding frame 6 is slid so that the first abutting part 801 slides along the connecting rod 4. When the sliding rod 8 slides to the other end of the connecting rod 4, it is checked whether there is a gap between the first abutting part 801 and the connecting rod 4. If there is a gap, the first telescopic member 9 is activated to keep the connecting rod 4 horizontal. Then the wall panel is placed between the first pressure roller 2, the second pressure roller 3 and the main body 1 of the device to perform the roll forming operation on the wall panel.

[0055] Furthermore, it also includes fasteners 10, which are disposed on the outside of several mounting plates 601. After the fasteners 10 are tightened, the installation space is reduced, restricting the position of the sliding rod 8 and the sliding bracket 6.

[0056] In this embodiment, the fastener 10 can be a pipe clamp. After the sliding rod 8 is adjusted to the required position within the installation space, the fastener 10 is installed on the outside of the mounting plate 601, so that the mounting plates 601 are brought closer together, thereby reducing the installation space.

[0057] The advantage is that the fastener 10 ensures that the sliding rod 8 remains in a fixed position during operation, preventing displacement or loosening due to vibration or external forces. This significantly improves product quality and consistency.

[0058] Furthermore, the main body 1 of the device includes a frame 101; a number of second mounting frames 102 are used in pairs, and the pairs of second mounting frames 102 are arranged opposite each other on both sides of the frame 101; the first mounting frame 5 is mounted on the main body 1 of the device through the second mounting frames 102; the sliding block 103 is used in combination with the second mounting frame 102, the sliding block 103 is vertically slidably arranged in the second mounting frame 102, the first pressure roller 2 is rotatably arranged on one of the pairs of sliding blocks 103, and the second pressure roller 3 is rotatably arranged on the other sliding block 103.

[0059] In this embodiment, the frame 101 is welded from heavy-duty channel steel and steel plates, possessing sufficient strength and rigidity to withstand the weight of the entire equipment and various forces during operation. The second mounting bracket 102 is connected to both sides of the frame 101 by high-strength bolts, and its surface undergoes precision machining to ensure the fitting accuracy with the sliding block 103. The sliding block 103 is made of wear-resistant alloy material, and the sliding fit between the sliding block 103 and the second mounting bracket 102 is achieved through a high-precision linear guide rail and slider, ensuring that the sliding block 103 can slide smoothly and accurately in the vertical direction. The first mounting bracket 5 is firmly fixed to the second mounting bracket 102 by welding or bolting, and its position and angle are precisely designed and adjusted to meet the installation and operation requirements of the sliding bracket 6. In actual operation, when it is necessary to adjust the height of the first pressure roller 2 and the second pressure roller 3, the lifting mechanism on the operating equipment is used to drive the sliding block 103 to slide vertically within the second mounting bracket 102.

[0060] The advantages are that the frame 101, as the basic support structure of the equipment, ensures the stability of the entire equipment during operation through its robust design and manufacturing. It effectively resists vibrations and impacts generated during operation, extending the equipment's service life. The combined design of the second mounting bracket 102 and the sliding block 103 provides reliable structural support and precise motion guidance for the height adjustment of the first pressure roller 2 and the second pressure roller 3. This design makes the height adjustment of the pressure rollers simple and quick. Operators can adjust the height of the pressure rollers in a short time according to different wall panel thicknesses and process requirements, greatly improving the equipment's production efficiency and adaptability, and meeting the needs of different customers and production tasks.

[0061] Furthermore, the main body 1 of the device also includes a fixed roller 104, which is rotatably mounted on the second mounting frame 102, and a forming space is formed between the fixed roller 104, the first pressure roller 2, and the second pressure roller 3.

[0062] In this embodiment, the fixed roller 104 is made of high-quality alloy steel with a specially treated surface, exhibiting high hardness, high wear resistance, and good corrosion resistance. It is mounted on the second mounting bracket 102 via precision bearings and bearing seats, ensuring smooth rotation. During equipment operation, the relative positions of the fixed roller 104 with the first pressure roller 2 and the second pressure roller 3 are precisely designed and adjusted to form a suitable forming space. For example, when the wall panel enters the forming space, the first pressure roller 2 and the second pressure roller 3 apply pressure to the wall panel from both sides, while the fixed roller 104 provides support and auxiliary rolling pressure from below. When producing different types of wall panels, the distance and pressure between the fixed roller 104 and the first pressure roller 2 and the second pressure roller 3 can be adjusted according to the material, thickness, and shape requirements of the wall panel.

[0063] The advantage is that the forming space formed by the fixed roller 104, the first pressure roller 2, and the second pressure roller 3 provides a stable and reliable working environment for the roll forming of the wall panel. This design can effectively reduce quality problems such as deformation and wrinkling of the wall panel during the roll forming process, improving the product qualification rate and quality stability. At the same time, by adjusting the forming space, it can adapt to the production of different types and specifications of wall panels, improving the versatility and flexibility of the equipment.

[0064] Furthermore, the main body 1 of the device also includes a gear 105, which is rotatably disposed on the side of the sliding block 103 away from the first pressure roller 2, and the gear 105 is connected to the first pressure roller 2 in a transmission manner; the first driving member 106 is disposed on the frame 101, and the output end of the first driving member 106 has gear teeth; there are several transmission wheels 107, which are rotatably disposed on the side of the second mounting frame 102 away from the first pressure roller 2, and the transmission wheels 107 mesh with both the gear teeth and the gear 105.

[0065] In this embodiment, gear 105 is mounted on the side of sliding block 103 away from the first pressure roller 2 and is connected to the first pressure roller 2 in a transmission manner. First drive member 106 is securely mounted on frame 101, and its output end has a toothed structure. Multiple transmission wheels 107 are sequentially arranged on the side of second mounting bracket 102 away from the first pressure roller 2. When the equipment starts running, first drive member 106 is activated, and the teeth at its output end begin to rotate. These teeth mesh with the teeth of transmission wheels 107, causing transmission wheels 107 to rotate. Since transmission wheels 107 mesh with gear 105, gear 105 also rotates. The rotation of gear 105 further drives the first pressure roller 2, which is connected to it in a transmission manner, to rotate. Simultaneously with the rotation of the first pressure roller 2, the second pressure roller 3 also begins to rotate synchronously through the action of linkage 4.

[0066] The advantage lies in the fact that this transmission system, composed of the first drive component 106, the transmission wheel 107, and the gear 105, can efficiently and stably transmit power to the first pressure roller 2 and the second pressure roller 3. This ensures that the pressure rollers continuously and stably receive the required power during the roll forming process of the wall panel, avoiding problems such as uneven rolling and equipment jamming caused by unstable power transmission, thereby greatly improving the stability and reliability of the equipment operation. By adjusting the output speed of the first drive component 106, the speed of the gear 105 and the transmission wheel 107 can be precisely controlled, thereby achieving precise adjustment of the speed of the first pressure roller 2 and the second pressure roller 3. This is crucial for the roll forming of wall panels of different thicknesses and materials. The speed of the pressure rollers can be flexibly adjusted according to actual production needs to achieve the best rolling effect and ensure the forming quality of the wall panel.

[0067] Furthermore, the main body 1 of the device also includes a guide plate 14, which is disposed at one end of the frame 101.

[0068] In this embodiment, the guide plate 14 plays a crucial guiding role in the actual operation of the roll forming machine for wall panels used in container houses. Without the guide plate 14, the wall panels might scatter or collide randomly due to lack of guidance, affecting the orderly progress of production.

[0069] The advantage lies in the fact that the guide plate 14, through its specific shape and position, can effectively guide the roll-formed wall panels to move in a predetermined direction. This avoids a chaotic distribution of wall panels during discharge, ensuring orderly discharge and facilitating subsequent wall panel collection, transportation, or further processing, thus greatly improving the overall efficiency of the production process. With the guidance of the guide plate 14, the wall panels can smoothly slide to the designated area, reducing the possibility of collisions between wall panels or with surrounding equipment and objects. This is crucial for protecting the surface quality and overall structural integrity of the wall panels, reducing the damage rate caused by collisions, and saving production costs.

[0070] Furthermore, it also includes a third mounting bracket 11, which is mounted on the frame 101 and located in the unloading section of the second mounting bracket 102. The wall panel passes through the third mounting bracket 11. The second telescopic member 12 is mounted on the third mounting bracket 11. The cutting blade 13 is mounted on the extended end of the second telescopic member 12 and is slidably mounted on the third mounting bracket 11 at both ends. After the second telescopic member 12 extends, the cutting blade 13 approaches the wall panel.

[0071] In this embodiment, the third mounting frame 11 is welded from robust metal materials and securely mounted on the frame 101 by bolts or welding, located in the unloading section of the second mounting frame 102. Its structural design is precisely calculated and optimized to withstand the impact and vibration generated during the cutting process of the wall panel. The second telescopic member 12 can be a hydraulic cylinder or a pneumatic cylinder, possessing sufficient thrust and stroke. It is mounted on the third mounting frame 11 via a flange or bracket, and its extension and retraction speed and stroke can be adjusted according to production needs. The cutting blade 13 is made of high-strength alloy steel, possessing a sharp blade and good wear resistance. It is mounted on the third mounting frame 11 via a slider or guide rail, ensuring smooth movement during the cutting process. After the wall panel is roll-formed and enters the third mounting frame 11, the second telescopic member 12 is activated according to the required wall panel length. The extended end of the second telescopic member 12 pushes the cutting blade 13 towards the wall panel. Guided by the guide device on the third mounting frame 11, the cutting blade 13 performs a precise linear cutting operation on the wall panel. During the cutting process, the quality and accuracy of the cutting can be ensured by adjusting the pressure and speed of the second telescopic member 12, as well as the position and angle of the cutting blade 13.

[0072] The advantage lies in the fact that the combined arrangement of the third mounting bracket 11, the second telescopic component 12, and the cutting blade 13 allows the equipment to immediately perform the cutting operation after the wall panel is rolled and formed, realizing an integrated production process and greatly improving production efficiency. This design reduces the handling and transfer of wall panels between different devices, thereby reducing labor intensity and production costs.

[0073] Furthermore, it also includes guide rods 15, a number of which are arranged inside the first mounting bracket 5, and the sliding bracket 6 is slidably arranged on the guide rods 15.

[0074] In this embodiment, during the actual operation of the roll forming machine for wall panels of container houses, the guide rods 15 play a crucial supporting and guiding role in the stable sliding of the sliding frame 6. Several guide rods 15 are arranged within the first mounting frame 5. The sliding frame 6 cooperates with the guide rods 15 through specific connecting structures such as sliding sleeves or sliders, allowing the sliding frame 6 to slide along the guide rods 15. When the equipment starts operating and the position of the sliding frame 6 needs adjustment, the sliding frame 6 will slide longitudinally along the guide rods 15. Due to the presence of the guide rods 15, the sliding frame 6 will not experience shaking, offset, or jamming, and can accurately reach the predetermined position to meet production needs under different working conditions.

[0075] The advantage is that the guide rod 15 provides a clear sliding path for the sliding frame 6, enabling it to maintain a precise movement trajectory during longitudinal sliding. This is crucial for the accurate adjustment and operation of the equipment, ensuring that all components on the sliding frame 6, such as the mounting plate 601 and the sliding rod 8, can accurately reach the required positions, thereby guaranteeing the processing accuracy of the wall panel. The high strength and stable support of the guide rod 15 effectively reduce the vibration and sway of the sliding frame 6 during sliding. Even under high-speed operation or high pressure, the sliding frame 6 can still maintain stable operation, avoiding equipment failure or processing errors caused by unstable factors, greatly improving the operational stability and reliability of the equipment.

[0076] Furthermore, both the first pressure roller 2 and the second pressure roller 3 have a second abutting part 201. The second abutting part 201 has a first angle with the horizontal plane. The first angle is α. The first angle gradually increases from the feeding end to the third mounting frame 11.

[0077] In this embodiment, in the actual operation of the roll forming machine for wall panels of container houses, a roll forming area is formed between the first pressure roller 2, the second pressure roller 3, and the fixed roller 104. The second contact portion 201 designed on the first pressure roller 2 and the second pressure roller 3 has a specific angle α with the horizontal plane. For example, when the wall panel just enters the starting end of the roll forming area, α is set to 2°. This small angle makes the pressure on the wall panel when it first enters the roll forming area extremely small. As the wall panel slowly moves towards the third mounting frame 11, the value of α begins to gradually increase. When the wall panel moves to a position about one-third of the roll forming area length away from the third mounting frame 11, α may increase to 5°; when the wall panel continues to move forward and reaches a position about two-thirds of the roll forming area length away from the third mounting frame 11, α further increases to 8°; finally, when the wall panel moves to one end of the roll forming area close to the third mounting frame 11, α increases to 12°.

[0078] During actual operation, the wall panel enters the rolling zone between the first pressure roller 2, the second pressure roller 3, and the fixed roller 104 from one side of the main body 1. Initially, because the angle α between the second contact portion 201 and the horizontal plane is small, the pressure on the wall panel at the beginning of the rolling zone is relatively weak, greatly reducing the possibility of wall panel deformation or feeding difficulties due to sudden high pressure. As the wall panel continues to move forward, α gradually increases, and the pressure on the wall panel gradually intensifies. During this process, the first pressure roller 2 and the second pressure roller 3 cooperate with the fixed roller 104, working together to progressively increase the rolling pressure on the wall panel.

[0079] The advantage is that at the beginning of the rolling zone, due to the smaller angle α between the second abutment 201 and the horizontal plane, the initial pressure on the wall panel is smaller, allowing the wall panel to enter the rolling zone more smoothly. This avoids problems such as wall panel position displacement, deformation, or feeding jamming caused by excessive pressure during feeding. This not only improves the smoothness of feeding but also greatly enhances the stability and reliability of the feeding process. As the wall panel gradually moves towards the third mounting bracket 11 in the rolling zone, α gradually increases, and the pressure on the wall panel also gradually increases. This makes the wall panel more evenly stressed throughout the rolling process, avoiding various problems caused by excessive or insufficient local pressure. Uniform pressure distribution helps improve the forming quality of the wall panel and reduces problems such as local deformation and inconsistent thickness caused by uneven pressure. Both the surface flatness and overall dimensional accuracy of the wall panel are significantly improved under this optimized rolling effect. For wall panels of different materials and thicknesses, the angle α between the second abutment 201 and the horizontal plane can be flexibly adjusted to easily adapt to the characteristics of different wall panels and rolling requirements. For example, for thinner or softer wall panels, the initial α value can be appropriately reduced to avoid damage caused by excessive pressure. Conversely, for thicker or harder wall panels, the variation range of α can be increased to ensure sufficient roller pressure. This design greatly enhances the equipment's adaptability to different types of wall panels, broadens its application range, and enables the equipment to perform excellently in various production scenarios.

[0080] Furthermore, the sliding bracket 6 is threadedly connected to the sliding rod 8.

[0081] In this embodiment, the sliding frame 6 is provided with an internal threaded hole, and the sliding rod 8 is provided with a matching external thread. When it is necessary to adjust the position of the sliding rod 8, the sliding rod 8 is rotated, and the thread transmission is used to make the sliding rod 8 move precisely within the installation space of the sliding frame 6.

[0082] The advantage lies in the high precision and ease of adjustment of the threaded connection.
