Description

Technical Field

[0001] This utility model belongs to the field of automotive parts processing technology, and in particular relates to a stamping mold for automotive clutch damper discs. Background Technology

[0002] The clutch damper disc is an important component of the clutch system. It effectively absorbs and attenuates torsional vibrations, preventing them from being directly transmitted to other parts of the transmission system. This reduces shock and wear, improving the comfort and reliability of the transmission system. For example, during rapid acceleration or braking, the damper disc significantly reduces the impact on the transmission system.

[0003] Patent CN202021282117.0 discloses a shock absorber spring disc stamping device, including a base, a support above the base, a lower die cylinder above the base, the lower die cylinder being tightly welded to the base, a concave die inside the lower die cylinder, a buffer plate below the concave die, and several compression springs below the buffer plate, with the upper and lower ends of the compression springs being tightly welded to the buffer plate and the lower die cylinder, respectively; an electric cylinder below the support, the upper end of the electric cylinder being welded and fixed to the support, an upper die cylinder below the electric cylinder, the upper die cylinder being welded and fixed to the electric cylinder, a convex die inside the upper die cylinder, and the convex die being bonded to the inner wall of the upper die cylinder with adhesive; this device changes the traditional spring disc stamping device which lacks shock absorption and buffering effect, facilitating precise stamping, extending the service life of the die, and improving stamping efficiency.

[0027] This disclosure will now be described in detail with reference to the accompanying drawings and embodiments.

[0028] like Figure 1-5 As shown, a stamping die for an automotive clutch shock absorber disc includes an upper die base 1, a punch 2, a lower die base 3, and a die 4. The punch 2 is fixed on the upper die base; the lower die base 3 is vertically aligned with the upper die base; the die 4 is fixed on the lower die base and has a through hole 41 that mates with the punch, allowing waste material generated during stamping to fall directly through the through hole; a mounting groove 41 is provided on the bottom surface of the lower die base 3, and a mounting plate 42 is detachably mounted in the mounting groove 41. Multiple mounting sleeves 421 are fixed on the mounting plate 42, and the mounting sleeves are correspondingly positioned to mate with the through hole. The sleeve is equipped with a first elastic element 43, which is a spring. One end of the spring is fixed to the mounting plate, and the other end is fixed to the ejector rod 44. When it is inconvenient for the worktable of the stamping machine to drop the scrap, the first elastic element is aligned with each through hole, and then the mounting plate is fixed in the mounting groove. When the punch presses downward, it will press down the ejector rod. After the stamping is completed, the punch moves upward, and the first elastic element will push the ejector rod upward, thereby ejecting the scrap. The mounting plate 42 is equipped with screws 45, and the mounting groove is equipped with threaded holes that mate with the screws for easy disassembly.

[0029] In other embodiments, a buffer hole 31 is provided on the lower mold base 3, and a second elastic element 32 is provided in the buffer hole 31. The second elastic element 32 is a spring, one end of which is fixed in the buffer hole and the other end is fixed with an elastic block 33. A guide rod 34 is fixed on the upper mold base 1. The guide rod is arranged corresponding to the buffer hole, so the impact of the buffer is reduced by the second elastic element and the elastic block.

[0030] In other embodiments, a connecting plate 11 is fixed on both the upper mold base 1 and the lower mold base 3. The connecting plate has a round hole 111 to facilitate the installation of the upper mold base and the lower mold base.

[0031] In other embodiments, slide rails 5 are fixed on both sides of the lower die base 1, and slide rails 5 are provided with slide plates 51, which can slide relative to the slide rails; a fixing post 52 is fixed on the slide plate 51; a positioning sleeve 53 is sleeved on the fixing post 52, which is used to position the workpiece. Positioning holes are opened on the workpiece before stamping; a fastening bolt 54 is screwed onto the slide plate 51, and the end of the fastening bolt can abut against the slide rail. By moving the slide plate, the position of the positioning post can be adjusted to meet the positioning holes at different distances on the workpiece. After adjustment, tightening the fastening bolt will fix the slide plate. Furthermore, the positioning sleeves with different wall thicknesses can be replaced to adapt to the diameter of the positioning holes of different workpieces; the fixed column 52 has an installation hole; a third elastic element 55 is provided in the installation hole, the third elastic element 55 is a spring, one end of which is fixed in the installation hole, and the other end is fixed with a push rod 56; a ball 57 is rotatably connected to the end of the push rod 56, and the inner wall of the positioning sleeve is provided with a groove that mates with the ball. When the positioning sleeve is completely fitted on the fixed column, the ball is aligned with the groove, and the third elastic element will push the ball into the groove to prevent the positioning sleeve from falling off the fixed column.

[0032] In other embodiments, the screw 45 is provided with an internal hexagonal groove 451 to facilitate rotation of the screw.

[0033] The above description is merely a selection of preferred embodiments of this disclosure and an explanation of the technical principles employed. Those skilled in the art should understand that the scope of the invention involved in the embodiments of this disclosure is not limited to technical solutions formed by specific combinations of the above-described technical features, but should also cover other technical solutions formed by arbitrary combinations of the above-described technical features or their equivalents without departing from the above-described inventive concept. For example, technical solutions formed by substituting the above-described features with (but not limited to) technical features with similar functions disclosed in the embodiments of this disclosure.
