Description

Technical Field

[0001] This utility model relates to the field of square stretching die technology, and in particular to a device for internal rotary cutting in a square stretching die. Background Technology

[0002] Precision drawn products are thin-walled hollow metal parts or tubes manufactured through precision stamping and drawing processes. Molds are used to plastically deform metal sheets, forming precision parts with complex geometries. The processing of precision drawn products requires the use of a square drawing die in-mold rotary cutting device. For example, a square drawing die in-mold rotary cutting device disclosed in application number 201921971821.4, through the arrangement of a connecting slider, side plate, first ball bearing, and rotary cutting guide groove, allows the first ball bearing at the end of the side plate to slide along the rotary cutting guide groove in the cavity during rotary cutting. This restricts the cutting direction and position of the cutting tool, precisely positioning the rotary cutting angle and distance, greatly improving the accuracy of the rotary cutting, resulting in a good rotary cutting effect that meets the requirements of high-precision processing.

[0003] However, the above structure cannot effectively expand the rotary cutter during use, thus making it unsuitable for use with molds of different specifications, reducing its applicability and efficiency. Furthermore, it cannot effectively oscillate the rotary cutter, thus preventing effective rotary cutting and reducing its rotary cutting efficiency and work efficiency.

This structure allows for effective expansion of the rotary cutting blade, enabling it to adapt to the use of molds of different specifications, thus improving its applicability and efficiency.

[0026] The bottom of the rotating tube 7 is bolted to an inner coupling tube 10, and an outer coupling tube 11 is sleeved on the inner coupling tube 10. An air jet pipe 13 is movably connected to the inner coupling tube 10 via a bearing. The bottom of the outer coupling tube 11 is bolted to an annular plate 23, and the bottom end of the air jet pipe 13 passes through the annular plate 23 and is sleeved with a rotating plate 22. Several evenly distributed translation plates 17 are slidably connected to the top of the annular plate 23, and grooves 16 are formed on the opposite sides of the translation plates 17.

[0027] Working principle: When using this technical solution, first open the opening and closing door, then place the mold in the placement slot 28, then close the opening and closing door. Subsequently, the electric jack 2 retracts, causing the docking plate 5 to move the moving cover 6 downward to cover the mold. Through the rotating tube 7 and other components, the rotary cutter 15 is driven into the mold. Then, the drive motor 29 drives the air jet pipe 13 to rotate through the worm 31 and worm wheel 30. The air jet pipe 13 drives the rotating plate 22 to rotate. The rotating plate 22 squeezes the round rod 21 through the arc groove 18, causing the round rod 21 to drive the translation plate 17 and the rotary cutter 15 to close or move away, so that it can effectively expand the rotary cutter, thereby adapting to the use of molds of different specifications, improving its applicability and efficiency.

[0028] Subsequently, the electric telescopic rod 26 extends and drives the piston block 25 to slide inside the rotating tube 7. The piston block 25 drives the rotary cutter 15 to swing through the sliding plate 9 and the docking rod 14, so that it can swing effectively, thereby enabling it to perform effective rotary cutting, improving its rotary cutting efficiency and working efficiency. The rotary motor 4 drives the rotary cutter 15 to rotate through the electric telescopic rod 26 and the rotating tube 7 and other components to achieve rotary cutting.

[0029] The blower 12 directs air into the jet pipe 13 and into the air guide groove 19 through the internal air guide hole 20. Then, it sprays out through the external air guide hole 20, which can blow the waste into the placement groove 28. Afterward, the placement plate 27 can be removed by opening the door and removing the bolts, which can facilitate the processing of waste.
