Description

Technical Field

[0001] This invention relates to the field of colored stone metal tile production technology, specifically to a stamping die for colored stone metal tile production. Background Technology

[0002] Colored stone metal roofing sheets are high-performance roofing materials made with aluminized zinc-coated steel sheets as the base material and colored sand particles bonded and sintered onto the surface using water-based acrylic ester. They are lightweight, aesthetically pleasing, durable, environmentally friendly, and easy to install, and are widely used in high-end residences, public buildings, and roof renovation projects such as flat-to-slope roof conversions. Their typical structure includes an aluminized zinc alloy layer, a fingerprint-resistant protective layer, an acrylic ester bonding layer, a sintered colored sand layer, and an acrylic resin protective layer. This allows them to adapt to various roof slopes and maintain stable performance under harsh weather conditions such as extreme cold, heavy rain, and strong winds. In actual production, colored stone metal roofing sheets typically undergo unwinding, cutting, and stamping processes. The stamping die is the key equipment for forming the metal substrate into specific corrugated tiles.

[0003] However, current colored stone metal tile production lines also have some technical shortcomings before stamping: First, the metal substrate is long and thin after unwinding and before cutting, and its tension is insufficient. During transportation, it is easy to drag on the ground, resulting in the adhesion of sand and other particulate impurities to the surface. Since most production lines are not equipped with effective surface cleaning devices, these impurities are pressed into the metal sheet during subsequent stamping, which seriously affects the appearance quality and structural integrity of the finished product. Second, after stamping, the stacking of tiles still relies on manual operation, which is not only inefficient, but also requires frequent interruptions during pallet replacement, significantly increasing the labor intensity of workers, thus restricting the improvement of the overall automation level and production efficiency. Summary of the Invention

[0004] In order to overcome the shortcomings of the prior art, the present invention provides a stamping die for the production of colored stone metal tiles.

[0005] The technical solution is as follows: A stamping die for producing colored stone metal tiles includes a base plate, a machine base, and a machine frame. Machine bases are fixedly installed on both sides of the top surface of the base plate. A machine frame is fixedly installed on the top of the machine base. At least two electric rollers are installed on the machine frame near the feeding side. These electric rollers are used to transfer the substrate to be stamped (such as aluminum-zinc coated flat coil) to the stamping die. The die also includes a lower die, columns, a top plate, an upper die, and hydraulic cylinders. Lower dies are fixedly installed inside the machine frames on both sides of the machine base. Multiple columns are fixedly connected to the four corner edges of the top of the machine base on both sides. The tops of these columns are connected to the same top plate. An upper die is slidably installed on the columns on the same side. The upper die, in conjunction with the lower die, is used to stamp the metal tile substrate. Two hydraulic cylinders are fixedly installed on the top plate for driving the upper die. A cleaning mechanism for cleaning the substrate is provided on the machine frame near the feeding side. The cleaning mechanism includes a guide frame, cleaning rollers, a first gearbox, and a first motor. The guide frame is fixedly connected to the feeding side of the machine frame. Openings are provided on both sides of the guide frame. The machine is equipped with a feed inlet. Two cleaning rollers for cleaning the substrate are rotatably connected inside the guide frame. A first gearbox is provided on one side of the guide frame. The two output shafts of the first gearbox rotate in opposite directions and are respectively connected to the two cleaning rollers. A first motor for driving its input shaft is installed on the first gearbox. A pushing mechanism is provided near the lower mold of the machine frame. The pushing mechanism is used to push out the metal tile substrate that has been pressed. A stacking mechanism for automatically stacking and pushing out the metal tile substrate is provided in the middle of the bottom surface of the top plate. Two substrates to be stamped are transferred to the corresponding cleaning mechanism via electric rollers. The cleaning mechanism drives the two cleaning rollers synchronously through the first motor and the first gearbox to clean the substrates that have passed through. The cleaned substrates are then transferred to the lower mold. Subsequently, the hydraulic cylinders on both sides drive the upper mold to stamp the substrates on the lower mold on the same side. After stamping, the metal tile substrates are pushed out of the lower mold by the pushing mechanism. The metal tile substrates pushed out on both sides are moved to the stacking mechanism. Finally, the stacking mechanism is used to automatically stack the metal tile substrates.

[0006] Furthermore, the two cleaning rollers are arranged one after the other and staggered vertically. Sponge rollers are installed on the cleaning rollers. The surfaces of the two sponge rollers are staggered and spiral-shaped. The bottom of the guide frame is a sloped surface inclined to one side. A collection cylinder is fixedly installed at the lowest point of the slope inside the guide frame. The collection cylinder is used to collect dust and impurities that fall during cleaning.

[0007] Furthermore, the pushing mechanism includes a fixed plate, connecting rods, a push plate, and an electric push rod. A fixed plate is fixedly connected to the frame on one side of the lower molds on both sides. Connecting rods are slidably connected to both sides of the fixed plate. The two connecting rods are connected to the same push plate. The bottom of the push plate is wavy and adapted to the shape of the stamping surface of the lower mold. An electric push rod is fixedly installed on the fixed plate. The piston rod of the electric push rod passes through the fixed plate and is connected to the push plate. The lower mold cooperates with the upper mold to complete the stamping of the metal tile substrate. After the hydraulic cylinder drives the upper mold to move upward and separate from the lower mold, the electric push rod is activated. The electric push rod drives the push plate to push the metal tile substrate on the lower mold along the connecting rod.

[0008] Furthermore, the stacking mechanism includes a first cylinder, a second gearbox, a second motor, a rotating shaft, and a support plate. A vertically downward-facing first cylinder is fixedly installed in the top plate. The piston rod of the first cylinder passes through the top plate and is fixedly connected to the second gearbox. A second motor for driving its input shaft is installed on the top of the second gearbox. Rotating shafts are fixedly connected to two co-directional output shafts at the bottom of the second gearbox. Support plates are symmetrically fixedly connected to the bottom of each rotating shaft on both sides. The support plates are used to horizontally support the metal tile substrate. Guide plates for guiding the support plates are fixedly connected to opposite sides of the machine base on both sides. The top surface of the guide plate is flush with the lower mold. The pushing mechanism pushes the metal tile substrates on both sides of the lower mold onto the guide plate. After being horizontally guided by the guide plate, the two metal tile substrates are pushed onto the support plate. Then, the first cylinder drives the second gearbox, rotating shaft, and support plate to move down to the target stacking position. Finally, the second motor, in conjunction with the second gearbox, drives the rotating shafts on both sides to rotate, so that the support plates on both sides rotate 90 degrees simultaneously, and the two supported metal tile substrates are placed down to the target stacking position at the same time. After the material is placed, the first cylinder returns to its original position, and the support plate rotates and unfolds again, ready to receive the next metal tile substrate for stacking.

[0009] Furthermore, the rotating shaft is equipped with a pressing mechanism for limiting the supported metal tile substrate. The pressing mechanism includes a sliding frame, a second cylinder, and a spring. The sliding frame is located next to the rotating shaft, and pressure plates that cooperate with the support plate are located on both sides of the bottom of the sliding frame. The sliding frame does not contact the rotating shaft. The second cylinder is fixedly installed on the top of the second gearbox housing. The piston rod of the second cylinder passes downward through the gearbox housing and the sliding frame in sequence. A spring is provided between the piston rod of the second cylinder and the sliding frame. When the piston rod of the second cylinder extends, the piston rod of the second cylinder will pull down the sliding frame through the spring, so that the sliding frame can elastically press down the metal tile substrate on the support plate, thereby improving the stability of the stacking mechanism in stacking the metal tile substrate downward.

[0010] Furthermore, the bottom surface of the pressure plate on both sides of the sliding frame is provided with a buffer pad, which is used to flexibly contact the metal tile substrate to avoid damage to the surface of the metal tile substrate when it is pressed down.

[0011] Furthermore, a transfer roller frame is fixedly installed in the middle of the top surface of the base plate. The transfer roller frame is located between the two machine bases. A stacking rack is placed on the transfer roller frame. The transfer roller frame is used for electric transfer of the stacking rack. The stacking rack is used for batch stacking of metal tile substrates. The transfer roller frame is used to transfer the stacking rack to the area directly below the stacking mechanism. The stacking mechanism works together to continuously stack the stamped metal tile substrates onto the stacking rack. Finally, the stacking rack with the stacked metal tile substrates is sent out by the transfer roller frame.

[0012] Furthermore, a positioning mechanism for precisely positioning the stacking rack is provided at the bottom of the top plate. The positioning mechanism includes guide rods and a positioning frame. Two guide rods are fixedly connected to the bottom of the top plate near the conveyor roller frame. A positioning frame for precisely limiting the stacking position of the stacking rack is slidably connected to the guide rods. The upper part of the positioning frame contacts the outer shell of the second gearbox, and the lower part of the positioning frame blocks the discharge side of the conveyor roller frame. Initially, the positioning frame accurately blocks the stacking rack at the position where the metal tile substrates are stacked. When the stacking rack is full of metal tile substrates, the first cylinder drives the reset second gearbox to continue moving upward a certain distance, causing the second gearbox to push the positioning frame upward, so that the positioning frame no longer blocks the stacking rack, allowing the conveyor roller frame to smoothly send out the stacking rack full of metal tile substrates.

[0013] Compared with the prior art, the present invention has the following advantages: 1. This invention achieves full automation from feeding to stacking of stamped finished products by using electric rollers for automatic feeding, a cleaning mechanism for synchronous cleaning, and dual-station stamping, combined with an automatic pushing mechanism for automatic pushing and a stacking mechanism for automatic stacking, thus significantly improving production efficiency.

[0014] 2. The pushing mechanism of the present invention uses an electric push rod to drive a wave-shaped push plate, which can push the stamped metal tile out of the mold completely and without damage. The stacking mechanism achieves synchronous and neat stacking of two metal tiles by lifting the cylinder and flipping the pallet driven by the motor.

[0015] 3. The positioning mechanism of the present invention is linked with the positioning frame through the guide rod. When the stacking rack is not full, the stacking position is accurately positioned. When the rack is full, the stacking mechanism automatically lifts and releases the limit, so that the transmission roller frame automatically sends out the full-load stacking rack and connects to the empty rack, realizing unmanned continuous operation.

Detailed Implementation

[0026] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the present invention or its application or use. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0027] Please refer to a stamping die for the production of colored stone metal tiles. Figures 1-6As shown, the machine includes a base plate 1, a base 2, and a frame 3. Base 2 is fixedly installed on both sides of the top surface of the base plate 1. A frame 3 is fixedly installed on the top of the base 2. Two electric rollers 31 are installed on the side of the frame 3 near the feed. The electric rollers 31 are used to transfer the substrate to be stamped (such as galvanized sheet / coil) to the stamping die. The machine also includes a lower die 4, columns 5, a top plate 6, an upper die 7, and hydraulic cylinders 8. Lower dies 4 are fixedly installed inside the frame 3 on both sides of the base 2. Multiple columns 5 are fixedly connected to the four corners of the top of both sides of the base 2. The tops of the multiple columns 5 are connected to the same top plate 6. Upper dies 7 are slidably installed on the multiple columns 5 on the same side. The upper die 7, in conjunction with the lower die 4, is used to stamp the metal tile substrate 100. Two hydraulic cylinders 8 are fixedly installed on the top plate 6 to drive the upper die 7. The frame 3 is located near the feed side. A cleaning mechanism 9 for cleaning the substrate is provided on the feeding side. The cleaning mechanism 9 includes a guide frame 91, cleaning rollers 92, a first gearbox 94, and a first motor 95. The guide frame 91 is fixedly connected to the feeding side of the machine frame 3. The guide frame 91 has material passages on both sides. Two cleaning rollers 92 for cleaning the substrate are rotatably connected inside the guide frame 91. The first gearbox 94 is provided on one side of the guide frame 91. The two output shafts of the first gearbox 94 rotate in opposite directions and are respectively connected to the two cleaning rollers 92. The first motor 95 for driving its input shaft is installed on the first gearbox 94. A pushing mechanism 10 is provided near the lower mold 4 of the machine frame 3. The pushing mechanism 10 is used to push out the metal tile substrate 100 that has been pressure-bearing. A stacking mechanism 11 for automatically stacking and pushing out the metal tile substrate 100 is provided in the middle of the bottom surface of the top plate 6.

[0028] Please see Figure 2 and Figure 3 As shown, two cleaning rollers 92 are arranged one after the other and staggered vertically. Sponge rollers 93 are installed on the cleaning rollers 92. The surfaces of the two sponge rollers 93 are staggered spirals. The bottom of the guide frame 91 is a slope that slopes to one side. A collection cylinder 96 is fixedly installed at the lowest point of the slope inside the guide frame 91. The collection cylinder 96 is used to collect dust and impurities that fall during cleaning.

[0029] When using this stamping die, after the equipment is started, the control system first activates the electric roller 31 on the feeding side. Multiple electric rollers 31 rotate, pulling the substrate (cut aluminum-zinc plated sheet roll) from the feeding side into the machine frame 3. The front end of the substrate first enters the guide frame 91 of the cleaning mechanism 9. Under the limit of the material inlets on both sides of the guide frame 91, the substrate is guided through the space between two sponge rollers 93. At the same time, the first motor 95 starts and drives the two cleaning rollers 92 to rotate in opposite directions through the first gearbox 94. Since the surfaces of the two sponge rollers 93 are provided with staggered spiral grooves, the two sponge rollers 93 can repeatedly wipe the upper and lower surfaces of the substrate during rotation, effectively removing dust and debris attached to the surface of the plate. The cleaned-off impurities fall onto the slope at the bottom of the guide frame 91 under the action of gravity, and finally slide into the collection cylinder 96 along the inclined slope for centralized storage, thereby ensuring that the surface of the substrate entering the stamping process is clean and avoiding damage to the coating or substrate during stamping.

[0030] Please see Figure 4 and Figure 5 As shown, the feeding mechanism 10 includes a fixed plate 101, a connecting rod 102, a push plate 103, and an electric push rod 104. The fixed plate 101 is fixedly connected to the frame 3 on one side of the lower molds 4. The connecting rods 102 are slidably connected to both sides of the fixed plate 101. The two connecting rods 102 are connected to the same push plate 103. The bottom of the push plate 103 is wavy and adapted to the shape of the stamping surface of the lower mold 4. The electric push rod 104 is fixedly installed on the fixed plate 101. The piston rod of the electric push rod 104 passes through the fixed plate 101 and is connected to the push plate 103.

[0031] Please see Figure 1 , Figure 6 and Figure 7 As shown, the stacking mechanism 11 includes a first cylinder 111, a second gearbox 112, a second motor 113, a rotating shaft 114, and a support plate 115. The first cylinder 111 is fixedly installed vertically downward in the top plate 6. The piston rod of the first cylinder 111 passes through the top plate 6 and is fixedly connected to the second gearbox 112. The second motor 113 for driving its input shaft is installed on the top of the second gearbox 112. The rotating shaft 114 is fixedly connected to the two output shafts in the same direction at the bottom of the second gearbox 112. The support plate 115 is symmetrically fixedly connected to the bottom of the rotating shafts 114 on both sides. The support plate 115 is used to horizontally support the metal tile substrate 100. The guide plate 12 for guiding the support plate 115 is fixedly connected to the opposite side of the machine bases on both sides. The top surface of the guide plate 12 is flat with the lower mold 4.

[0032] After cleaning, the substrate continues to move forward with the electric roller 31 until it is fully inserted into the stamping station of the lower mold 4 and stops. At this time, the two hydraulic cylinders 8 installed on the top plate 6 simultaneously extend their piston rods, driving their respective upper molds 7 to slide vertically downwards along the four corner columns 5. The upper molds 7 and lower molds 4 close precisely, and under the action of huge stamping pressure, the flat substrate is stamped into the preset metal tile substrate 100 in one go. After holding the pressure for a short time, the hydraulic cylinders 8 drive the upper molds 7 to return to their original position, making room for unloading. Immediately after the stamping is completed, the unloading stage begins, and the electric push rods 104 on both sides start simultaneously, and the electric push pistons... The rod extends and drives the push plate 103 to push out. Since the bottom of the push plate 103 is designed to be wave-shaped and fully fit the stamping surface of the lower mold 4, during the pushing process, the push plate 103 smoothly contacts and pushes the formed metal tile substrate 100 along the connecting rod 102, causing it to separate from the cavity of the lower mold 4. As the push plate 103 continues to push forward, the metal tile substrate 100 is completely pushed out of the lower mold 4 and slides horizontally along the guide plate 12 on the inner side of the machine base 2. Since the top surface of the guide plate 12 is flush with the upper surface of the lower mold 4, the metal tile substrate 100 can smoothly transition and finally slide into the tray 115 on the same side of the stacking mechanism 11.

[0033] Please see Figure 6 and Figure 7 As shown, a pressing mechanism 13 for limiting the supported metal tile substrate 100 is provided on the rotating shaft 114. The pressing mechanism 13 includes a sliding frame 131, a second cylinder 132 and a spring 133. The sliding frame 131 is provided next to the rotating shaft 114. Pressure plates that cooperate with the support plate 115 are provided on both sides of the bottom of the sliding frame 131. The sliding frame 131 does not contact the rotating shaft 114. The second cylinder 132 is fixedly installed on the top of the housing of the second gearbox 112. The piston rod of the second cylinder 132 passes through the housing of the gearbox and the sliding frame 131 in sequence. A spring 133 is provided between the piston rod of the second cylinder 132 and the sliding frame 131.

[0034] Please see Figure 7 As shown, buffer pads 134 are provided on the bottom surfaces of the pressure plates on both sides of the sliding frame 131. The buffer pads 134 are used to flexibly contact the metal tile substrate 100 to prevent damage to the surface of the metal tile substrate 100 when it is pressed down.

[0035] Please see Figure 1 and Figure 8 As shown, a transfer roller frame 14 is fixedly installed in the middle of the top surface of the base plate 1. The transfer roller frame 14 is located between the two machine bases 2. A stacking rack 15 is placed on the transfer roller frame 14. The transfer roller frame 14 is used for electric transfer of the stacking rack 15. The stacking rack 15 is used for batch stacking of metal tile substrates 100.

[0036] At the instant the metal tile substrate 100 falls onto the support plate 115 on the same side, the pressing mechanism 13 begins to engage. The second cylinder 132, located at the top of the second gearbox 112, extends its piston rod. Since a spring 133 is provided between the piston rod and the sliding frame 131, this drive is a flexible transmission. After being subjected to force, the sliding frame 131 slides downward, causing the pressure plates on both sides of its bottom to descend until the buffer pad 134 on the bottom surface of the pressure plate contacts the upper surface of the metal tile substrate 100. At this time, the presence of the spring 133 allows the pressure plate to apply a constant force. A moderate but gentle pressure prevents the metal tile substrate 100 from shifting due to shaking during subsequent descent, while also avoiding damage to its surface due to excessive pressure. After the metal tile substrate 100 is reliably pressed, the first cylinder 111 is activated, and its piston rod extends, pushing the connected second gearbox 112 to descend as a whole. The second gearbox 112, rotating shaft 114, support plate 115, and pressing mechanism 13, as a whole, carry the two metal tile substrates 100 vertically downwards, while simultaneously transmitting... The conveyor roller frame 14 transports the stacking rack 15 to the area directly below the stacking mechanism 11. When the pallet 115 has descended to a preset height above the stacking rack 15, the piston rod of the second cylinder 132 retracts first, causing the pressure plate on the sliding frame 131 to lift and stop pressing down on the metal tile substrate 100. Then, the first cylinder 111 stops operating. Immediately afterward, the second motor 113 starts, driving the rotating shafts 114 on both sides to rotate synchronously by 90 degrees through the second gearbox 112. As the rotating shafts 114 rotate, the metal tile substrate, which was originally horizontally and longitudinally supported, is now lifted. The pallet 115 of the 100 rotates to a horizontal position, and the support of the pallet 115 on the metal tile substrate 100 disappears instantly. The two metal tile substrates 100 fall smoothly onto the stacking rack 15 below, achieving precise stacking. After release, the first cylinder 111 retracts and drives the pallet 115 to reset upward. Then, the second motor 113 drives the rotating shaft 114 to rotate 90 degrees, so that the pallet 115 returns to a horizontal position. Finally, the entire stacking mechanism 11 is raised to the initial receiving height, ready to receive the next set of metal tile substrates 100.

[0037] Please see Figure 1 and Figure 9 As shown, a positioning mechanism 16 for precisely positioning the stacking rack 15 is provided at the bottom of the top plate 6. The positioning mechanism 16 includes guide rods 161 and positioning frame 162. Two guide rods 161 are fixedly connected at the bottom of the top plate 6 near the conveyor roller frame 14. The positioning frame 162 for precisely limiting the stacking position of the stacking rack 15 is slidably connected on the guide rods 161. The upper part of the positioning frame 162 contacts the outer shell of the second gearbox 112, and the lower part of the positioning frame 162 blocks the material discharge side of the conveyor roller frame 14.

[0038] Throughout the stacking process, the positioning mechanism 16 ensures that the stacking rack 15 is always in a precise receiving position. Initially, the lower part of the positioning frame 162 blocks the discharge side of the conveyor roller frame 14. When an empty stacking rack 15 is fed in from the infeed side by the conveyor roller frame 14, the front end of the stacking rack 15 touches the positioning frame 162 and is blocked. At this time, the stacking rack 15 is directly below the stacking mechanism 11, meaning the drop point of the metal tile substrate 100 is directly opposite the center area of ​​the stacking rack 15. As the metal tile substrates 100 are stacked, the tiles on the stacking rack 15 gradually increase in height. When the stacking rack 15 is fully loaded with metal tile substrates 100, the stacking process is complete. The first cylinder 111, which resets upwards, does not stop but continues to rise a short distance. This extra stroke causes the housing of the second gearbox 112 to push upwards and contact the positioning frame 162. The positioning frame 162 slides upwards along the guide rod 161, and its lower end disengages from the obstruction of the stacking rack 15. Subsequently, the transfer roller frame 14 starts to send the fully loaded stacking rack 15 out in the discharge direction, while sending the next empty stacking rack 15 into the work station. When the empty stacking rack 15 reaches the predetermined position, the first cylinder 111 resets and descends again. The positioning frame 162 slides down along the guide rod 161 due to gravity and falls down again to block the discharge side, preparing for the next round of stacking.
