[0002] The large evaporator tube sheet is a component that fixes and supports the evaporation tube and is one of the important components of chemical evaporation equipment. Since the evaporator tube sheet is 16mm thick and is a high-strength ultra-thick plate, a high-strength thick plate high-speed punching die is used in the processing of the high-strength thick plate.

[0003] The evaporator tube fixing groove of the existing large evaporator tube plate is formed by CNC milling machine, which will lead to low processing efficiency, high production cost, large punching force and short mold service life. Reducing the punching force can effectively extend the service life of the mold. The punch and the die generally adopt a relatively large punching gap. When punching thick plates with a large gap, the shear strength deviation of the high-strength thick plate is large, and the punching gap needs to be appropriately increased or reduced. Otherwise, the punching section will have the defect of falling off, resulting in defective products. Therefore, the existing thick plate mold has high requirements on the consistency value of the shear strength of the thick plate material, reduces the defective rate of falling off of the punching section, increases the number of samples, reduces the timeliness of purchasing materials, and affects production efficiency.

[0004] Therefore, we provide a high-strength thick plate high-speed punching die. Utility Model Content

[0033] Working principle: First, a high-strength thick plate high-speed punching die is moved to the working position. The first step is to turn on the power switch of the punching machine. The second step is to manually operate the punching machine and adjust the crankshaft of the punching machine to the upper dead center. At this time, the upper die part of the evaporator tube sheet slot punching die rises to the highest point with the punching machine, and the die spacing reaches the maximum. The third step is to hoist the evaporator tube sheet onto the bracket, adjust the step distance of the feeder, and insert the evaporator tube sheet into the upper end of the concave module 23 through the sliding wheel 222. The fourth step is to press the start switch of the punching machine, and the slider of the punching machine drives the upper die part of the evaporator tube sheet slot punching die to move downward, the unloading plate presses the evaporator tube sheet, and the upper die part continues to move downward. The punch 13 cuts into the evaporator tube sheet, and the waste is separated from the evaporator tube sheet. At this time, the evaporator The tube sheet groove is formed, and the punching machine slider drives the upper mold to move upward to complete a working cycle. The above actions are automatically repeated until thirteen evaporator tube sheet grooves are punched. In the fifth step, during the punching process, the waste material slides from the inside of the lower mold plate 21 to the inside of the storage shell 4 through the groove 231 to complete the collection. In the sixth step, when the waste material in the storage shell 4 needs to be poured out, the corner block 5 is slid out of the inside of the storage shell 4, and the card block 51 is slid out of the inside of the card groove 42. In the seventh step, the connecting plate 43 is disconnected from the positioning hole 211, and the rotating shaft 41 rotates inside the rotating seat 31, and the storage shell 4 rotates and contacts the baffle 212. At this time, the storage shell 4 is tilted and the waste material is removed. In this way, the use process of a high-strength thick plate high-speed punching die is completed.
