[0037] As Figures 1 to 4 The embodiment provides a material sheet processing equipment, which comprises a rack 1, a material sheet forming die 2 and a press driving mechanism 3. The material sheet forming die 2 comprises a first punching die 21, a second punching die 22 and a counterbore die 23 arranged on the rack 1, the first punching die 21 is used for forming a first drain hole 101 of a material sheet 100 to be processed (as shown in Figure 5 And Figure 6 The second punching die 22 is used for forming a second drain hole 102 of the material sheet 100 to be processed, and the counterbore die 23 is used for processing the circular first drain hole 101 into a counterbore with a radially turned edge; the press driving mechanism 3 is arranged on the rack 1 and is used for driving the upper die and the lower die of the first punching die 21, the second punching die 22 and the counterbore die 23 to be combined. The working principle of the counterbore die 23 is mainly that a concave shape similar to the surface of the material sheet is pressed out through a forming punch, so that the counterbore is obtained. The working principle of the punching die is that the punch and the die of the die are used for punching the material sheet. The structure of the punching die is relatively simple, which mainly comprises an upper die holder, a guide column, a guide sleeve, a punch, a die and a lower die holder.

[0038] When the material sheet is processed, the press driving mechanism 3 drives the upper die and the lower die of the first punching die 21 to close, so that the first punching die 21 shapes the first drain hole 101 of the material sheet 100 to be processed, the first drain hole 101 belongs to the conventional inner tube drain hole, the press driving mechanism 3 drives the upper die and the lower die of the second punching die 22 to close, so that the second punching die 22 shapes the second drain hole 102 of the material sheet 100 to be processed, the second drain hole 102 is different from the first drain hole 101, the second drain hole 102 belongs to the water-repellent leaf drain hole, the inner tube usually has a small amount of water-repellent leaf drain hole and a large amount of conventional inner tube drain hole, the press driving mechanism 3 drives the upper die and the lower die of the counterbore die 23 to close, so that the counterbore die 23 processes the circular first drain hole 101 into a counterbore with a radially flanged edge, which can prevent clothes from being scratched by the edge of the drain hole during washing, and can effectively reduce the noise and vibration generated during washing of the washing machine. The material sheet processing equipment adopts a set of press driving mechanism 3 to drive the first punching die 21, the second punching die 22 and the counterbore die 23 to close, which saves time and effort, has high processing efficiency and high integration. The material sheet processing equipment not only can completely process the inner tube ring material sheet meeting the above design requirements, but also can be applied to the full-automatic production line of the inner tube of the washing machine, so as to realize the high-efficiency automatic production of the inner tube of the washing machine.

[0039] Optionally, the second punching die 22 is provided with an adjusting cylinder 221, which is used to drive the upper die and the lower die of the second punching die 22 to close. When the second punching die 22 is needed to work, the adjusting cylinder 221 pushes the adjusting plate out, and the upper die and the lower die of the second punching die 22 are closed to complete the shaping of the second drain hole 102. At the time of not needing to process the second drain hole 102, the adjusting cylinder 221 pulls the adjusting plate back, at this time, the upper die and the lower die of the second punching die 22 are closed, and the second punching die 22 is not in action.

[0040] Since the second drain hole 102 is arranged in a small amount of intervals, the material sheet shaping die 2 also comprises a detection module 24, which can detect the second drain hole 102 of the material sheet 100 to be processed. Through the detection of the position of the second drain hole 102 by the detection module 24, the processing rhythm of the material sheet 100 to be processed can be reasonably arranged.

[0041] Optionally, the detection module 24 comprises a driving cylinder and a detection pin, and the driving cylinder is used to drive the detection pin to insert into the second drain hole 102 of the material sheet 100 to be processed. The driving cylinder inserts the detection pin into the second drain hole 102, realizes the accurate positioning of the material sheet 100 to be processed, and ensures the position accuracy of the first drain hole 101 and the second drain hole 102.

[0042] Optionally, the press driving mechanism 3 comprises a driving member 31 and a die closing member 32, the die closing member 32 is slidingly arranged on the frame 1, and the driving member 31 is used to drive the die closing member 32 to drive the upper die and the lower die of the first punching die 21, the second punching die 22 and the counterbore die 23 to close. The driving member 31 can adopt a hydraulic driving mode, which can accurately adjust the blanking force of the die closing member 32, and can also adopt a mechanical limiting precise control of the die closing height. The press driving mechanism 3 can also adopt a mechanical punch structure, and can also adopt a servo motor drive.

[0043] In order to ensure the stable conveying of the to-be-processed sheet 100 on the production line, the sheet forming die 2 can further comprise an auxiliary supporting mechanism 25 for supporting the to-be-processed sheet 100. The auxiliary supporting mechanism 25 can be in the form of a plurality of rolling rollers, and the to-be-processed sheet 100 is conveyed to the sheet forming die 2 stably under the support of the rolling rollers. The auxiliary supporting mechanism 25 can be provided with one on each side of the sheet forming die 2, which can ensure the stable conveying of the feeding and the stable conveying of the discharging.

[0044] In order to avoid the deviation of the to-be-processed sheet 100 during conveying, the sheet forming die 2 can further comprise a guide mechanism 26 for guiding and pressing the to-be-processed sheet 100 in the width direction of the to-be-processed sheet 100. The guide mechanism 26 can specifically clamp the two sides of the to-be-processed sheet 100 through two rows of clamping wheels to ensure that the to-be-processed sheet 100 is conveyed in a straight line in the length direction.

[0045] In order to facilitate automatic continuous operation, the sheet processing equipment can further comprise a feeding mechanism 4 for conveying the to-be-processed sheet 100 to the sheet forming die 2. The feeding mechanism 4 can detect by a self-contained encoder, complete accurate feeding according to the specific interval and size of the first drainage hole 101 and the second drainage hole 102 of the to-be-processed sheet 100, and the feeding speed is steplessly adjustable.
