Description

Technical Field

[0002] The general status of related technologies in this field: Sheet metal stamping technology is an important process in modern industrial manufacturing and is widely used in the automotive, home appliances, electronics and other industries. With the advancement of industrial automation, high-speed and high-precision sheet metal stamping machines have become key equipment for the development of the industry. Traditional sheet metal stamping machines usually use fixed stamping dies to achieve sheet metal stamping by closing the upper and lower dies. With the development of technology, automatic sheet metal stamping machines are now widely popular on the market, that is, they automatically complete the loading and stamping process without worker intervention. However, most automatic sheet metal stamping machines have the disadvantage of being unable to achieve high speed. During the high-speed operation of the automatic sheet metal stamping machine, its sheet (steel plate) will produce greater friction with the equipment. This friction will cause sparks or hard wear between the equipment and the sheet, resulting in sheet metal debris flying out, causing equipment damage or production of defective products. Summary of the invention

[0032] Reference Figure 3 and Figure 4 The feeding device also includes a tensioning mechanism 5 and an active unloading arm 4 arranged on the winding frame 2. The active unloading arm 4 is rotatably provided with a spiral wire structure wheel 41 at one end close to the winding joint 21.

The tensioning mechanism 5 can also play an emergency stop role for the steel coil when unloading the steel coil. The tensioning mechanism 5 is used to tighten the steel coil and control the unloading speed of the steel coil. Since the coil is too loose as a whole, the coil is easily released by its own elastic force. The tensioning mechanism 5 can also prevent the steel coil from self-releasing.

Under the elastic force of the spring 882, the ejector section 884 is always in contact with the bottom of the core 87, so that the core 87 is always kept in an upwardly lifted state when the steel coil is not processed. The stamping top die 89 is fixedly set on the upper fixed frame 1001, and a stamping head 891 is fixedly set on the stamping top film. The stamping top film is driven by conventional hydraulic pressure. The punch head 891 cooperates with the core 87 to punch the shape of the steel plate. When the punch head 891 punches the steel plate, the core 87 moves downward and presses down the ejector body 881 under the downward pressure of the punch head 891, thereby compressing the spring 882. When the punching is completed, the ejector body 881 will push the core 87 upward under the elastic force of the spring 882, and keep the core 87 in an upward tilted state.

[0040] The oil supply device 10 includes an oil pump 101, an oil tank 103 and an oil pipe 102 fixedly arranged on a lower fixed frame 1002. In order to avoid the wear of the steel due to excessive friction when the steel plate contacts the device and ensure the smoothness of the equipment during high-speed processing, when the steel plate is clamped by the clamping device 6, oil holes 611 are opened at both ends of the upper pressing plate 614 and the lower pressing plate 615, and a sponge joint 612 is fixedly inserted in the oil hole 611. The other end of the oil hole 611 is connected to the oil pipe 102, and the oil in the oil tank 103 is pumped into the oil hole 611 through the oil pipe 102 by the oil pump 101. In the embodiment of the present application, the oil is designated as lubricating oil. When the oil is connected to the sponge joint 612, it can be absorbed by the sponge joint 612. One end of the sponge joint 612 plugged into the upper pressing plate 614 and the lower pressing plate 615 is set to be cylindrical and matches the shape of the oil hole 611, and the other end is set to be a long strip with the same length as the pressing plate 61. When the oil is absorbed by the sponge joint 612, it will flow evenly to all parts of the sponge joint 612. A row of brushes 613 are fixedly set at one end of the sponge joint 612. The brushes 613 can drain the oil absorbed by the sponge joint 612. When the steel plate passes through the pressing plate 61, the brushes 613 can contact the steel plate, thereby evenly smearing the oil on the steel plate.

[0041] An oil outlet hole 83 connected to the oil delivery pipe 102 is provided on the side wall of the assembly hole 84, and a sealing scraper ring 885 is sleeved on the sealing section 883 of the ejector body 881. The sealing scraper ring 885 is connected to the inner side wall of the assembly hole 84. When the ejector body 881 moves up and down in the assembly hole 84, the sealing hanging ring moves up and down with the ejector body 881. When the sealing hanging ring moves to the highest point, it is flush with the top of the assembly hole 84 and the thickness of the sealing hanging ring can still block the oil outlet hole 83. When the sealing hanging ring moves to the lowest point, the top of the sealing hanging ring is at the bottom position of the oil outlet hole 83, and the oil outlet hole 83 can leak oil. Through the above arrangement, when the ejector body 881 moves up and down once, the oil is pumped out to the mold cavity 86 once by the sealing scraper ring 885. The fixed seat 85 is also provided with a reflux port 851 , which is provided at a certain height from the lower pad 82 . This arrangement enables the oil in the mold cavity 86 to reflux and be recovered through the reflux port 851 when the oil level reaches the reflux port 851 .

[0042] The implementation principle of the embodiment of the present application is as follows: an automated high-speed sheet metal stamping machine of the present application automatically transports the steel plate released from the steel coil to the clamping device through the feeding device, and the side clamping plate 91 clamps the two ends of the steel plate to clamp and move the steel plate. When the side clamping plate 91 is clamped and moved, the upper pressing plate 614 and the lower pressing plate 615 are separated. When the side clamping plate 91 does not move, the upper pressing plate 614 and the lower pressing plate 615 clamp the steel plate. The steel plate moved to the leveling device 7 is placed on the pressure plate 71 and adsorbed by the magnetic induction coil 72 set at the bottom of the pressure plate 71, so that when the side clamping plate 91 does not tighten the steel plate, the steel plate can maintain its original position. The flattening counterweight block 73 flattens the bent steel plate, and moves from the side clamping plate to the stamping device 8 for stamping and forming, thereby realizing the automatic stamping process of the steel plate. Through the setting of the oil supply device 10, oil can be applied to the steel plate to reduce the friction between the steel plate and the equipment, thereby ensuring the stability of the high-speed operation of the stamping machine.

[0043] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
