Description

Technical Field

[0002] Hemming machines are widely used in furniture manufacturing, automotive interior and other industries, mainly for hemming the edges of plates or other workpieces. This process not only enhances the aesthetics of the product, but also improves its durability and service life. Traditional hemming processes usually rely on manual operation or semi-automatic equipment for edge hemming. These methods are often inefficient and have limited precision, making them difficult to adapt to large-scale production needs. In addition, with the continuous advancement of production technology, more and more companies are looking for more automated and intelligent production equipment to reduce human operating errors, improve production efficiency and product quality. Therefore, developing an hemming device that can be precisely controlled, highly automated and easy to operate has become an important research direction in the manufacturing industry.

[0003] However, in the prior art, the existing hemming machines have some technical deficiencies in actual use. Traditional hemming equipment mostly adopts mechanical or semi-automatic control, which is complicated to operate and has poor flexibility, and is difficult to adapt to the coating requirements of different workpieces. Secondly, the lifting and lowering adjustment of the equipment often relies on manual adjustment, which can easily lead to uneven hemming or inaccurate positioning of the workpiece, affecting the quality of the final product. In addition, the manually controlled hemming process is less efficient, and due to the complex operation, workers need to undergo a long period of training to master the operation of the equipment, which increases production costs. Therefore, we provide a high-frequency pressing hemming machine and pressing hemming process.

[0055] A pressing and hemming process, used in a high-frequency pressing and hemming machine, is characterized by comprising the following steps:

[0056] S1: placing the equipment to be pressed and hemmed in the coating mechanism 2 or the high-frequency pressing mechanism 3;

[0057] S2: Afterwards, the staff can use the human-machine interface touch screen dialogue window to set parameters of the system operation mode, switch between manual and automatic operation, and control the machine motion through the interface, and compress the coating mechanism 2 or the high-frequency pressing mechanism 3 by controlling the hemming mechanism 1;

[0058] S33A: The coating mechanism 2 coats the device;

[0059] S33B: The three pairs of high-frequency pressing devices instantly activate the glue through the upper membrane, stamp the shape of the upper membrane onto the surface of the skin, and finally continue to maintain pressure on the mold and cool it to shape.

[0060] Furthermore, in step S1 and step S2, the control system is placed in a position that is convenient for the operator to operate and observe. The equipment is provided with necessary emergency stop switches according to the specific situation, and has overload protection and short-circuit protection functions. When the line of the equipment touches the shell, the control system cuts off the power supply of the line within 0.1 seconds. There are measures to prevent the wear of the wires around the outlet of the distribution cabinet. The wiring of the equipment without joints in the middle of the power cord is transported by standard wire troughs or insulating tubes and cannot be installed directly on the ground. The distribution cabinet and peripheral equipment are connected with aviation plugs or terminal blocks.

[0061] Furthermore, in the step S33A, the wrapped product is placed on the lower fetal membrane, and the start switch is pressed to automatically close the mold for automatic wrapping, and the product is automatically reset after the wrapping is completed.

[0062] In order to further improve its practicality in actual use, the staff can use the wrapping mechanism 2 to wrap it after completing the edging. The staff will place the workpiece with completed edging on the lower tire mold 25 on the bottom template 29, and then align the upper tire mold 24 on the upper template 21 with the meshing mouth of the lower tire mold 25. At the corresponding positions of the upper tire mold 24 and the lower tire mold 25, the upper sleeve 22 will be nested and adjusted with the embedded rod 210. Finally, the staff only needs to control the first cylinder 27 to reverse the wrapping and the second cylinder 28 to push the skin, so that its practicality in actual use is further improved.

[0063] When the staff uses the high-frequency pressing mechanism 3 to press the materials, they can place the materials in the lower mold groove 35 on the bottom plate 36, and then connect them with the docking column 32 by using the docking rod 34, so that the lower mold groove 35 and the upper mold 33 can be pressurized. The servo motor can accurately control the mold height during the upper and lower mold closing. The equipment emits high frequency to instantly activate the glue through the upper fetal membrane, and stamp the shape of the upper fetal membrane onto the surface of the epidermis. Finally, the mold is kept under pressure and cooled to shape.

[0064] The working principle of the above embodiment is: when the staff uses the hemming machine to hem the product, they can place the product to be hemmed in a position that is convenient for the operator to operate and observe, and then control the operating table 18 to allow the upper hemming plate 19 and the lower hemming plate 110 to be compositely extruded to complete the hemming. After completing the hemming, the staff needs to take out the product and place it in the coating mechanism 2, and then control the start switch to automatically close the mold for automatic coating, and automatically reset after completing the coating. In this way, the hemming and coating of the product can be completed, and the present assembly line is convenient for the staff to operate and process, which improves the convenience for the staff to a certain extent.

[0065] In order to further improve the practical application effect of the equipment, after the hemming is completed, the staff can use the hemming mechanism 2 to hem it. First, the hemmed workpiece is placed on the lower tire mold 25 on the bottom template 29, and then the upper tire mold 24 on the upper template 21 is aligned and engaged with the lower tire mold 25. In this step, the upper sleeve 22 and the embedded rod 210 are nested and adjusted to ensure that the workpiece is accurately positioned. Finally, the staff only needs to control the first cylinder 27 to perform the reverse operation and use the second cylinder 28 to push the skin to finally complete the hemming.

[0066] At the same time, a second different coating method is provided for the staff to choose. When using the high-frequency pressing mechanism 3 for coating, the staff can place the material in the lower mold groove 35 on the bottom plate 36, and then connect it with the docking column 32 by using the docking rod 34, so that the lower mold groove 35 and the upper mold 33 can be pressurized. The mold height is accurately controlled by the servo motor during the upper and lower mold closing. The equipment emits high frequency to instantly activate the glue through the upper fetal membrane, and the shape of the upper fetal membrane is stamped onto the surface of the epidermis. Finally, the mold is continuously pressurized and cooled to shape. This series of operations significantly improves the practicality and efficiency of the equipment in actual use.

[0067] Finally, it should be noted that the above are only preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
