Description

[0001] The present application relates to the technical field of colored stone metal tile manufacturing, and particularly relates to an automatic molding device for colored stone metal tile production. BACKGROUND

[0002] As a high-performance roofing material, colored stone metal tile is widely used in various fields due to its light weight, corrosion resistance, rich color and other advantages. Its production mainly adopts automatic molding process, which processes the metal substrate (such as aluminum-zinc plated steel plate) into a specific wave structure through stamping or rolling, and then sprays adhesive and covers colored stone particles to finally form a finished product with both decorative and functional properties.

[0003] However, in the existing production process, metal scraps are easily left on the surface of the cut metal tile plate. These scraps will directly fall onto the mold surface during the conveying of the tile plate to the molding machine, causing the molding surface to be contaminated during molding, and thus producing local concave-convex defects. This condition not only affects the appearance quality of the product, but also can cause functional problems, such as reducing the waterproof performance and durability of the product. Secondly, during the extrusion of the metal tile plate by the upper and lower mold plates, a certain amount of heat is generated. Dust floating in the workshop will adhere to the mold surface under this high-temperature environment, further causing product size deviation or surface defects. The existence of these problems significantly increases the rate of defective products, increases production costs, and also reduces production efficiency.

[0004] Based on the above situation, there is an urgent need for an automatic molding device for colored stone metal tile production. SUMMARY

DETAILED DESCRIPTION

[0027] The application will be further described in combination with the drawings and examples.

[0028] Example 1: An automatic molding device for producing color stone metal tile, as shown in Figure 1 and Figure 3 , comprising a rack 1, the rack 1 is provided with symmetrically distributed hydraulic devices 21, the end portions of the piston rods of which are fixedly connected with a sliding frame 2, constituting a lifting driving mechanism; the sliding frame 2 vertically slides on the rack 1 and is driven to realize precise lifting through the extension and contraction of the piston rods of the hydraulic devices 21, providing stable and controllable power transmission for stamping molding; the bottom of the sliding frame 2 is provided with an upper die plate 4, and the workbench of the rack 1 is provided with a lower die plate 3, and the two complete high-efficiency stamping molding work of the color stone metal tile through precise cooperation.

[0029] In order to ensure the cleanliness of the stamping process, eliminate the interference of metal chips and dust on the quality of the die, a turbine fan 5 is installed on the sliding frame 2 to generate wind to clean the metal chips and dust on the surface of the upper die plate 4 and the lower die plate 3. The upper die plate 4 is provided with an upper air guide frame 7 for automatic cleaning of the surface of the upper die plate 4. The workbench of the rack 1 is provided with a lower air guide frame 9 for automatic cleaning of the surface of the lower die plate 3. The turbine fan 5 is provided with evenly distributed air guide pipes which are connected to the upper air guide frame 7 and the lower air guide frame 9 through branch pipes, forming a double-path cleaning system to realize omnidirectional cleaning function.

[0030] The workbench of the rack 1 is provided with evenly distributed clamping grooves, and the lower die plate 3 is detachably clamped on the workbench of the rack 1 through the clamping grooves. The bottom of the sliding frame 2 is provided with symmetrically distributed clamping members, and the upper die plate 4 is detachably clamped on the sliding frame 2 through the clamping members. This modular design realizes the quick replacement function of the die plate and improves the adaptability of the equipment.

[0031] Each air guide pipe of the turbine fan 5 is flexibly connected to the upper air guide frame 7 through an elastic tube 6 which has high elastic deformation capacity and can adapt to the distance change of the upper die plate 4 moving up and down in real time, ensuring uninterrupted wind transmission. Each air guide pipe of the turbine fan 5 is connected to the lower air guide frame 9 through a high-temperature-resistant hose 10 to form a safe connection mechanism. When the turbine fan 5 moves downward with the sliding frame 2, the hose 10 effectively avoids damage caused by stretching or bending due to its flexible nature, ensuring the continuous and stable operation of the cleaning function of the lower die plate 3.

[0032] The top of the upper air guide frame 7 is fixedly connected to symmetrically distributed positioning frames 701, and the upper air guide frame 7 is detachably clamped on the upper die plate 4 through the positioning frames 701 to realize the synchronous movement of the upper air guide frame 7 and the upper die plate 4, ensuring that the surface of the upper die plate 4 can be cleaned in time and effectively during the whole stamping process.

[0033] Specifically, as shown in Figure 3 The workbench of the rack 1 is provided with a mounting frame 8, and the lower air guide frame 9 vertically slides on the mounting frame 8. Symmetrically distributed first springs 11 are connected between the lower air guide frame 9 and the mounting frame 8, and the symmetrically distributed first springs 11 are all wound on the mounting frame 8 to form an elastic buffer mechanism.

[0034] When the upper air guide frame 7 moves downward with the upper die plate 4, the first spring 11 plays a buffering and damping role during the folding of the upper and lower die plates 3, so that the lower air guide frame 9 can adaptively move downward to avoid obstacles caused by rigid contact, effectively preventing the normal folding and plate pressing of the upper and lower die plates 3.

[0035] Specifically, as shown in Figure 4 and Figure 5As shown, the upper air guide frame 7 is rotatably connected with an air guide plate 12, and the air direction of the air outlet of the upper air guide frame 7 can be flexibly controlled through precise angle adjustment. The two ends of the air guide plate 12 are provided with arc corners 131. The two ends of the upper air guide frame 7 are slidably connected with push frames 13. The push frames 13 are in contact with the adjacent arc corners 131. The side of the rack 1 close to the push frame 13 is fixedly connected with guide blocks 14. The guide blocks 14 are provided with inclined surfaces. The guide blocks 14 are in contact with the adjacent push frames 13.

[0036] Initially, the two push frames 13 are pressed inward by the guide blocks 14. The push frames 13 will push the air guide plate 12 upward through the arc corners 131, so that the air guide plate 12 is in an upward deflection state. At this time, the air blown out of the air outlet of the upper air guide frame 7 flows along the air guide plate 12 to the upper left at high speed, accurately removing metal scraps and dust in the gap of the complex structure on the surface of the upper mold plate 4, and maintaining the cleanliness of the upper mold plate 4. The sliding frame 2 is provided with guide grooves 141 on the side close to the guide blocks 14. The size of the guide grooves 141 matches the guide blocks 14. When the sliding frame 2 moves downward, the precise cooperation of the guide grooves 141 and the guide blocks 14 ensures that the sliding frame 2 can smoothly move downward, avoiding interference and hindering the stamping process.

[0037] Specifically, as shown in the drawings, Figure 6 The mounting frame 8 is slidably connected with symmetrically distributed clamping frames 15, forming an automatic locking mechanism. The symmetrically distributed clamping frames 15 are provided with inclined surfaces. The clamping frames 15 and the mounting frame 8 are connected with second springs 16. The second springs 16 are respectively wound around the adjacent clamping frames 15, constituting an elastic return system.

[0038] Specifically, as shown in the drawings, Figure 7 and Figure 8 Each clamping frame 15 is provided with a guide rod 17, constituting a linkage positioning mechanism. The side of the guide rod 17 close to the clamping frame 15 is provided with a guide inclined surface 172, forming an inclined surface guide structure. The guide rod 17 cooperates with the clamping frame 15 through the guide inclined surface 172, forming a dynamic cooperation relationship, so that the second spring 16 is always in a pre-compressed state, forming an elastic energy storage mechanism. At this time, the clamping frame 15 and the track line of the downward movement of the lower air guide frame 9 are arranged in spatial dislocation.

[0039] Each push frame 13 is fixedly connected with a connecting plate 173, forming a transmission connection mechanism. Each connecting plate 173 vertically slides on the adjacent guide rod 17, constituting a linear guide system. The side of the sliding frame 2 close to the guide rod 17 is provided with a sliding groove 171, forming a displacement limiting structure. The guide rod 17 horizontally slides in the sliding frame 2 through the sliding groove 171, constituting a horizontal adjustment mechanism.

[0040] Specifically, as shown in the drawings, Figure 9 The workbench of the rack 1 is fixedly connected with a sealing plate 18 on the side close to the mounting frame 8, constituting a selective sealing structure, which can automatically switch the cleaning mode according to the working state.

[0041] According to the required color stone metal tile specifications, the modular replacement of the upper die plate 4 and the lower die plate 3 is completed through the clamping groove and the clamping part, and the axis alignment of the upper and lower die plates 3 is ensured. The upper air guide frame 7 is clamped on the upper die plate 4 through the positioning frame 701, so that the air outlet is accurately positioned with the working surface of the die plate. In the initial state, the push frame 13 is limited to be retracted in by the guide block 14, and the air deflector 12 is pushed to be deflected upward by 30° through the arc corner 131. At the same time, the push frame 13 drives the guide rod 17 through the connecting plate 173, so that the guide inclined surface 172 abuts against the clamping frame 15, and the second spring 16 is compressed to the energy storage state.

[0042] When the metal substrate is conveyed to the lower die plate 3, the turbine blower 5 is started, and the wind force is conveyed to the upper air guide frame 7 and the lower air guide frame 9 through the telescopic pipe 6 and the hose 10 respectively. The upper air guide frame 7 is guided by the air deflector 12 to remove metal debris and dust in the complex structure on the surface of the upper die plate 4 in an oblique upward airflow; the lower air guide frame 9 synchronously blows the lower die plate 3 and the bottom surface of the substrate to avoid local concave-convex defects on the forming surface caused by debris pollution during stamping.

[0043] The control hydraulic device 21 drives the sliding frame 2 to move vertically downward, and drives the upper die plate 4, the turbine blower 5 and the upper air guide frame 7 to move downward synchronously. Further, the air deflector 12 and the push frame 13 are moved downward together. When the push frame 13 passes the guide block 14, the air deflector 12 is turned to the horizontal position under the action of gravity, and no longer guides the wind direction. The air outlet of the upper air guide frame 7 returns to the 5° downward inclination state. At this time, the wind blown by the upper air guide frame 7 directly acts on the upper surface of the metal substrate to clean it.

[0044] At the same time, the air deflector 12 turns and pushes the push frame 13 to move outward, drives the guide rod 17 to move outward through the connecting plate 173 and sleeves on the clamping frame 15, the guide inclined surface 172 of the guide rod 17 no longer abuts against the clamping frame 15, and the limiting of the clamping frame 15 is released. The second spring 16 releases the elastic force to make the clamping frame 15 slide into the lower air guide frame 9.

[0045] When the upper air guide frame 7 contacts the lower air guide frame 9, the first spring 11 is deformed. The lower air guide frame 9 is pressed down and contacts the inclined surface of the clamping frame 15, which will extrude the clamping frame 15 to move backward and compress the second spring 16. After passing the critical point, the spring resets to lock the position of the lower air guide frame 9. At this time, the upper and lower die plates 3 are closed to complete stamping, and the color stone metal tile is obtained. At the same time, the sealing plate 18 closes the air outlet of the lower air guide frame 9, and the wind force of the turbine blower 5 is blown out through the upper air guide frame 7.

[0046] After stamping, the control hydraulic device 21 drives the sliding frame 2 to reset upward, and the upper die plate 4 and the lower die plate 3 are separated. The upper air guide frame 7 concentrates the wind force of the turbine blower 5 to blow out, and directional cooling is performed on the formed tile to reduce the risk of thermal stress deformation.

[0047] With the upper air guide frame 7 continuing to move upward, the push frame 13 is in contact with the inclined surface of the guide block 14 and is retracted inward, the arc corner 131 resets the air guide plate 12 to the inclined air guide state, and the air is guided to blow upwardly and obliquely to clean the surface of the upper mold plate 4 and reduce the temperature; at the same time, the push frame 13 moving inward drives the guide rod 17 to move inward through the connecting plate 173, the guide rod 17 moves inward and pushes the clamping frame 15 away through the guide inclined surface 172, the clamping frame 15 moves backward, the second spring 16 returns to the initial state, and when the clamping frame 15 is separated from the lower air guide frame 9, the lower air guide frame 9 is unlocked and moves upward under the drive of the first spring 11 to reset, at this time, the air outlet of the lower air guide frame 9 is unsealed, air is blown to the lower mold plate 3 and the surface of the metal tile to further reduce the temperature and keep the lower mold plate 3 clean.

[0048] The metal tile which has been punched and formed is taken out, the metal substrate to be punched is continuously conveyed to the lower mold plate 3, and the above steps are repeated to perform the punching work. As described above, before punching, the upper air guide frame 7 and the lower air guide frame 9 blow air to clean the upper and lower mold plates 3 and the metal substrate; after punching, air blowing is performed again to reduce the temperature, so that the mold plate and the surface of the product are kept clean and the punching quality is improved.

[0049] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application and not to limit the protection scope of the present application. Although the present application has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present application can be modified or replaced equivalently without departing from the essence and scope of the technical solutions of the present application.
