For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0041] like Figures 1 to 4As shown, this embodiment provides a sheet processing device, which includes a frame 1, a sheet forming die 2 and a press drive mechanism 3. The sheet forming die 2 includes a first punching die 21, a second punching die 22 and a countersink die 23 arranged on the frame 1. The first punching die 21 is used to form a sheet 100 to be processed (such as Figure 5 and Figure 6 The first drainage hole 101 of the sheet 100 to be processed is formed by a second punching die 22, and a countersink die 23 is used to process the circular first drainage hole 101 into a countersink with a curved flange; the press driving mechanism 3 is arranged on the frame 1, and is used to drive the first punching die 21, the second punching die 22 and the upper die and the lower die of the countersink die 23 to close the mold. The working principle of the countersink die 23 is mainly to press a concave shape similar to it on the surface of the sheet by a forming punch, so as to obtain a countersink. The working principle of the punching die is to use the convex and concave dies of the die to punch the sheet. The structure of the punching die is relatively simple, and is mainly composed of an upper die seat, a guide column, a guide sleeve, a punch, a concave die and a lower die seat.

[0042] When processing the sheet, the press drive mechanism 3 drives the upper die and the lower die of the first punching die 21 to close the die, so that the first punching die 21 forms the first drainage hole 101 of the sheet 100 to be processed, and the first drainage hole 101 belongs to the conventional inner cylinder drainage hole. The press drive mechanism 3 drives the upper die and the lower die of the second punching die 22 to close the die, so that the second punching die 22 forms the second drainage hole 102 of the sheet 100 to be processed, and the second drainage hole 102 is different from the first drainage hole 101. The second drainage hole 102 belongs to the water-discharging leaf drainage hole. The inner cylinder usually has a small number of water-discharging leaf drainage holes and a large number of conventional inner cylinder drainage holes. The press drive mechanism 3 drives the upper die of the countersunk die 23 The tool is molded with the lower mold so that the countersink mold 23 processes the circular first drainage hole 101 into a countersink with a curved flange, which can prevent clothes from being scratched by the edge of the drainage hole during washing, and can also effectively reduce the noise and vibration generated during the washing process of the washing machine. The sheet processing equipment uses a set of press drive mechanism 3 to drive the first punching mold 21, the second punching mold 22 and the countersink mold 23 to perform mold closing operations, which saves time and labor, has high processing efficiency and high integration. The sheet processing equipment can not only completely process the inner drum ring sheet that meets the above-mentioned design requirements, but also can be used in the fully automated production line of the inner drum of the washing machine to realize high-efficiency automated production of the inner drum of the washing machine.

[0043] Optionally, the second punching die 22 is provided with an adjustment cylinder 221, and the adjustment cylinder 221 is used to drive the upper die and the lower die of the second punching die 22 to stagger when they are molded together. When the second punching die 22 is required to work, the adjustment cylinder 221 pushes the adjustment plate out, and the upper die and the lower die of the second punching die 22 are molded together to complete the forming of the second drainage hole 102. At the time when the second drainage hole 102 does not need to be processed, the adjustment cylinder 221 pulls the adjustment plate back. At this time, the upper die and the lower die of the second punching die 22 are staggered when they are molded together, and the second punching die 22 is inoperative.

[0044] Since the second drainage holes 102 are arranged at intervals in small quantities, the tablet forming mold 2 may further include a detection module 24, which can detect the second drainage holes 102 of the tablet 100 to be processed. By detecting the positions of the second drainage holes 102 by the detection module 24, the processing rhythm of the tablet 100 to be processed can be reasonably arranged.

[0045] Optionally, the detection module 24 includes a driving cylinder and a detection pin, and the driving cylinder is used to drive the detection pin to be inserted into the second drainage hole 102 of the to-be-processed sheet 100. The driving cylinder inserts the detection pin into the second drainage hole 102 to achieve accurate positioning of the to-be-processed sheet 100, thereby ensuring the positional accuracy of the first drainage hole 101 and the second drainage hole 102.

[0046] Optionally, the press drive mechanism 3 includes a drive member 31 and a clamping member 32, the clamping member 32 is slidably disposed on the frame 1, and the drive member 31 is used to drive the clamping member 32 to drive the upper mold and the lower mold of the first punching mold 21, the second punching mold 22 and the countersinking mold 23 to clamp. The drive member 31 can be hydraulically driven, and the punching force of the clamping member 32 can be accurately adjusted, and the clamping height can also be accurately controlled by mechanical limit. The press drive mechanism 3 can also adopt a mechanical punch structure, and can also be driven by a servo motor.

[0047] To ensure that the material 100 to be processed is smoothly conveyed on the production line, the material forming mold 2 may further include an auxiliary support mechanism 25, which is used to support the material 100 to be processed. The auxiliary support mechanism 25 may be a structure of multiple rollers, and the material 100 to be processed is smoothly conveyed to the material forming mold 2 under the support of the rollers. The auxiliary support mechanism 25 may be provided on both sides of the material forming mold 2, so as to ensure stable conveyance of both the loading and unloading materials.

[0048] To prevent the material sheet 100 to be processed from deviating during the conveying process, the material sheet forming mold 2 may further include a guide mechanism 26, which is used to guide and press the material sheet 100 to be processed along the width direction of the material sheet 100. The guide mechanism 26 may specifically clamp the two sides of the material sheet 100 to be processed through two rows of clamping wheels to ensure that the material sheet 100 to be processed is conveyed in a straight line along the length direction.

[0049] To facilitate automated continuous operation, the sheet processing equipment may further include a feeding mechanism 4, which is used to convey the sheet 100 to be processed to the sheet forming mold 2. The feeding mechanism 4 may be equipped with an encoder for detection, and accurately feed the sheet according to the specific spacing and size of the first drainage hole 101 and the second drainage hole 102 of the sheet 100 to be processed, and the feeding speed may be steplessly adjusted.

[0050] To facilitate cutting of the processed sheet, the sheet processing equipment may further include a cutting mechanism 5, which is used to cut the processed sheet. The cutting knife of the cutting mechanism 5 is used to cut the sheet after all the punching and countersinking of the current sheet are completed and the sheet reaches a fixed length. The driving method of the cutting mechanism 5 can adopt a cylinder, a linear motor, a gear rack or a screw press drive mechanism 3.

[0051] Of course, the sheet processing equipment also includes a control system 6, which controls the automatic operation of the whole machine. The most critical point is to control the coordinated operation between the hydraulic drive of the press drive mechanism 3, the feeding mechanism 4, the detection module 24, the guide mechanism 26 and the cutting mechanism 5. The mutual matching and coordinated operation between the component systems determine the dimensional accuracy and surface quality of the inner cylinder ring sheet. The layout dimensions and control procedures between the three parts of the sheet forming mold 2 need to be customized according to the characteristics and dimension drawings of the sheet, so the layout dimensions of the sheets of different models can be quickly modified.

[0052] The action sequence of each system of the sheet processing equipment is roughly as follows:

[0053] First, the feeding mechanism 4 feeds the sheet 100 to be processed to the initial position of the conveying direction in the sheet forming mold 2, and then, the guide mechanism 26 guides the sheet 100 to be processed in the width direction and presses the sheet 100 to be processed under the drive of the cylinder, and then, the first punching mold 21 of the sheet forming mold 2 is closed under the drive of the press drive mechanism 3, and the punching of four rows of first drainage holes 101 is completed at one time; then, the feeding mechanism 4 continues to feed to the first step distance (the distance between the first four rows and the last four rows of holes), the mold is closed, and after repeating the operation five times, the sheet 100 to be processed is sent to the punching station of the second drainage hole 102, and then, the second punching mold 22 is extended, the mold is closed, and the punching of four rows of first drainage holes 101 and one row of second drainage holes 102 is completed at the same time, and then the second punching mold 22 is withdrawn; the feeding mechanism 4 continues to feed and the mold is closed; after completing nine operations, the first row of the sheet 100 to be processed is completed. The second drainage hole 102 is sent to the detection pin station of the detection module 24; at this time, the detection pin is extended downward by the cylinder drive and inserted into the second drainage hole 102 (this action is used to detect whether the punching position size of the sheet after the previous operation is accurate), and the detection pin retracts after the detection is correct; then, the feeding mechanism 4 continues to feed and the mold is closed; after completing thirty-three operations, the drainage holes in the first span area on the sheet are all punched out; the servo feeding unit feeds to the second step, at this time the first four rows of first drainage holes 101 are just sent to the countersinking station of the countersinking mold 23; then, the mold is closed, and the composite operation condition of punching and countersinking flanging is entered at the same time; after the above process is repeated for ninety times, the drainage holes on the first sheet are all formed; then, the feeding mechanism 4 continues to feed the third step until the cumulative feeding size reaches the fixed length size of the sheet, and the cutting knife of the cutting mechanism 5 cuts off the processed sheet. Repeating the operation according to the above action sequence can realize the continuous automatic production of the inner cylinder ring sheet.

[0054] This embodiment also provides a sheet processing method, which processes the sheet by the sheet processing equipment, comprising the following steps:

[0055] The press driving mechanism 3 drives the upper die and the lower die of the first punching die 21 to close the die, so that the first punching die 21 forms the first drainage hole 101 of the material sheet 100 to be processed;

[0056] The press driving mechanism 3 drives the upper die and the lower die of the second punching die 22 to close the die, so that the second punching die 22 forms the second drainage hole 102 of the material sheet 100 to be processed;

[0057] The press driving mechanism 3 drives the upper mold and the lower mold of the countersinking mold 23 to close the mold, so that the countersinking mold 23 processes the circular first drainage hole 101 into a countersink with a curved flange.

[0058] When processing the sheet, the press drive mechanism 3 drives the upper die and the lower die of the first punching die 21 to close the die, so that the first punching die 21 forms the first drainage hole 101 of the sheet 100 to be processed, and the first drainage hole 101 belongs to the conventional inner cylinder drainage hole. The press drive mechanism 3 drives the upper die and the lower die of the second punching die 22 to close the die, so that the second punching die 22 forms the second drainage hole 102 of the sheet 100 to be processed, and the second drainage hole 102 is different from the first drainage hole 101. The second drainage hole 102 belongs to the water-discharging leaf drainage hole. The inner cylinder usually has a small number of water-discharging leaf drainage holes and a large number of conventional inner cylinder drainage holes. The press drive mechanism 3 drives the upper die of the countersunk die 23 The tool is molded with the lower mold so that the countersink mold 23 processes the circular first drainage hole 101 into a countersink with a curved flange, which can prevent clothes from being scratched by the edge of the drainage hole during washing, and can also effectively reduce the noise and vibration generated during the washing process of the washing machine. The sheet processing equipment uses a set of press drive mechanism 3 to drive the first punching mold 21, the second punching mold 22 and the countersink mold 23 to perform mold closing operations, which saves time and labor, has high processing efficiency and high integration. The sheet processing equipment can not only completely process the inner drum ring sheet that meets the above-mentioned design requirements, but also can be used in the fully automated production line of the inner drum of the washing machine to realize high-efficiency automated production of the inner drum of the washing machine.
