Description

Technical Field

[0001] The present invention relates to the technical field of wooden door production, and particularly to a wooden door hot stamping processing device. Background Art

[0002] Hot stamping is a wood processing technique that uses a high-temperature metal to iron the surface of wood, ablating the surface of the wood to make the wood change color and form delicate patterns. The hot stamping process is also used in wooden door production. In traditional wooden door hot stamping processing, a resistance wire is generally used to heat a hot stamping metal tool, and then the heated metal tool is used for hot stamping. The heating method using a resistance wire has a slow heating rate, and the temperature is difficult to control. The processing speed is slow with the method of heating first and then hot stamping. Moreover, the metal tool needs to be heated multiple times during the hot stamping process of the wooden door panel, resulting in low work efficiency. Summary of the Invention

[0003] To solve the above technical problems, the present invention provides a wooden door hot stamping processing device that adopts electromagnetic induction heating and pressure forming methods, with precise temperature control, fast processing speed, and high work efficiency.

[0004] A wood door hot stamping processing device of the present invention includes a bottom plate, a bearing plate, a plurality of telescopic square columns, two hydraulic cylinders, a mold frame, a top plate, a square frame support plate, a plurality of plastic springs and an electromagnetic ring. The bearing plate is located above the bottom plate. The plurality of telescopic square columns and the two hydraulic cylinders are respectively located at the left and right ends of the bottom plate and the bearing plate. The two ends of the plurality of telescopic square columns and the two hydraulic cylinders are respectively connected to the bottom plate and the bearing plate. The mold frame is installed in the middle of the upper end surface of the bearing plate. The top plate is connected to the bottom plate through a plurality of support rods. The top plate is located above the mold frame. The square frame support plate is elastically installed on the upper end surface of the bearing plate through a plurality of plastic springs. The mold frame is located in the middle of the square frame support plate, and the upper end surface of the square frame support plate is higher than the upper end surface of the mold frame. A driving mechanism of the electromagnetic ring is installed on the lower end surface of the bearing plate. The driving mechanism is in transmission connection with the electromagnetic ring. A guide coil is wound inside the electromagnetic ring. The bearing plate, the mold frame, the square frame support plate, the plurality of plastic springs and the top plate are all located in the guide coil of the electromagnetic ring. The bearing plate, the mold frame, the top plate and the square frame support plate are all made of non-metallic materials. Install the metal mold of the wood door pattern on the mold frame. At this time, the highest point of the metal mold is lower than the upper end surface of the square frame support plate. Place the wood door panel on the upper end surface of the square frame support plate and adjust the position. Operate the two hydraulic cylinders to extend. The plurality of telescopic square columns limit the bearing plate, so that the two hydraulic cylinders vertically push up the bearing plate. The wood door panel rises synchronously with the bearing plate. When the upper end surface of the wood door panel contacts the lower end surface of the top plate, the two hydraulic cylinders continue to extend. At this time, the plurality of plastic springs are compressed, so that the lower end surface of the wood door panel contacts the metal mold. The two hydraulic cylinders continue to extend, so that the metal mold presses out the pattern on the lower end surface of the wood door panel. The two hydraulic cylinders stop extending. The guide coil of the electromagnetic ring is energized to form a magnetic field inside the electromagnetic ring. The driving mechanism of the electromagnetic ring drives the electromagnetic ring to move from the right end of the bearing plate to the left end of the bearing plate. During the movement of the electromagnetic ring, the magnetic field formed by the guide coil of the electromagnetic ring sweeps across the metal mold, and the temperature of the metal mold is quickly raised to the set temperature. The high-temperature metal mold hot stamps and discolors the pressed pattern. Adopting the electromagnetic induction heating method, the metal mold has a fast heating speed and precise temperature control. Adopting the pressure forming method, the processing speed is fast, and there is no need to heat the metal tool multiple times, improving the work efficiency.

[0005] Preferably, it further includes two plastic slide bars, two spring telescopic rods, two tension springs, a cleaning roller, a rotating shaft and a reduction motor.

The reduction motor is installed on the outer wall of the lower end of one spring telescopic rod, and the output shaft of the reduction motor is in transmission connection with the rotating shaft. After the electromagnetic ring completes heating the metal mold and the metal mold finishes engraving the wooden door panel, the two hydraulic cylinders contract to lower the wooden door panel and separate it from the top plate, and then take out the engraved wooden door panel. Start the reduction motor, and the reduction motor drives the cleaning roller to rotate through the rotating shaft, and move the cleaning roller along the two plastic slide bars to clean the metal mold, removing the wood ash and black carbide on the metal mold to avoid these substances affecting the engraving quality and improving the product quality.

During the process of the electromagnetic ring moving to the right for reset, the two long rod hooks hooking the shaft rods on the spring telescopic rods and the reduction motors cause the cleaning roller to move synchronously to the right with the electromagnetic ring, so that the cleaning roller cleans the metal mold. When the electromagnetic ring reaches the right end of the bearing plate, the right ends of the two long rod hooks are guided downward by the guide planes of the two guide plates, causing the hooks at the left ends of the two long rod hooks to disengage from the shaft rods on the spring telescopic rods and the reduction motors, and the elastic force of the two tension springs pulls the two spring telescopic rods together with the cleaning roller back to the left end of the top plate, realizing automatic cleaning and reset, and improving work efficiency.

When the bearing plate rises so that the contact switches of the multiple height limiting seats contact the lower end surface of the top plate, the multiple height limiting seats send signals to stop the elongation of the two hydraulic cylinders. At this time, the metal mold is pressed into the wooden door panel to the set depth, improving the practicability of the equipment.
