Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of molds, in particular to a multi-sequence multi-position stamping die and a use method thereof. BACKGROUND

[0002] The stamping die is a special tool for stamping process in industrial production. Through the pressure machine, external force is applied to make metal or non-metal plate materials separate or plastically deform in the die, so as to obtain parts with specific shape and size. Its core function is to realize efficient, large-batch and high-precision production of parts, and it is widely used in automobile, electronic, home appliance and other industries. The multi-sequence multi-position stamping die is a kind of high-efficiency compound die, which can complete punching, stretching, bending, trimming and other processes in sequence through multiple stations in the same set of die. It significantly reduces the number of workpiece transmission and positioning, improves production continuity and efficiency, and is particularly suitable for production of parts with complex structure or requiring multi-step forming. This design not only saves equipment space, but also reduces the cost of single production. It is a key component of automatic stamping line. The common multi-sequence multi-position stamping die still needs manual removal of the die during use, which has production risks.

[0003] To solve the above problems, through retrieval, a patent with publication number CN108787901B discloses a multi-directional positioning stamping die. The document proposes "1. Through the combination of the top block, the positioning cone, the positioning cone groove, the partition plate, the positioning cone shell, the second spring and the bottom block, the positioning between the upper stamping die and the lower stamping die can be more accurate, avoiding inaccurate positioning between the upper stamping die and the lower stamping die, which can cause the die after stamping to not meet the production requirements, re-stamping the die, wasting time and effort, and increasing the labor time of the workers. 2. Through the combination of the third spring, the die plate, the die plate and the stamping shallow groove, not only can the die after stamping be ejected from the die guide-out mechanism, but also can the die after stamping play a certain buffering role, saving the process of workers taking the stamping die product out of the lower stamping die, greatly improving the work efficiency. 3. Through the combination of the pushing plate, the fourth spring, the pushing side plate, the pushing top plate and the rubber block, the ejected stamping die product can be pushed into the collection box, avoiding the process of workers using their hands to pick up the stamping die product, which can cause the upper stamping die to press the workers' fingers, causing injury to the workers. 4. Through the setting of the first spring, the back plate, the sliding groove type positioning mechanism and the stamping die body, the stamping die can be positioned in multiple directions, making the produced stamping die product higher in quality and easier to push to the market", although the die guide-out mechanism (such as the third spring and the die plate) is set to automatically eject the product after stamping, reducing the operation link of manual die removal and improving efficiency, but the spring ejection force is affected by the weight and adhesion of the workpiece. For light and thin or easily adhered workpieces, the demolding may not be complete, and manual assistance is still required.

A method of using a multi-series multi-position stamping as claimed in any one of claims 1 to 9, wherein, The following steps are included: S1, first, the plate is placed on the supporting frame (1502), then the plate is clamped in the second limiting column (1506), the second spring (1504) is stretched according to the width of the plate, the plate is limited, then the plate is pushed onto the first supporting table (2), and the air cylinder (12) and the first motor (702) are started; S2, the plate enters the workbench (3), the air cylinder (12) drives the pressing plate (11) to cold-press the plate, and a stamping die is output, then the pressing plate (11) is lifted, at this time, the first motor (702) drives the gear (703) to rotate, since the gear (703) is partially toothed, the rack (704) can be indirectly driven to move upward, and the first spring (705) provides a reset elastic force, so that the rack (704) is periodically moved up and down, the rack (704) moves up and down to drive the sliding block (706) to move up and down, and the die after stamping is pushed up, when the die is pushed up, the air bellow (801) is started; S3, the air bellow (801) is started, the wind force is blown out from the air bellow head (803) along the air pipe (802), the baffle (13) limits the diffusion of the wind force, the blown wind can blow the die to the screening mechanism (14), and the wind can also blow the debris generated by stamping, so that the subsequent stamping is prevented from being affected by the debris, the die enters the meshing vehicle (1404) of the screening mechanism (14), the meshing vehicle (1404) reciprocates under the drive of the second motor (1408) and the eccentric wheel (1409), the die and the debris can be screened out, the die and the debris are separated, and therefore the clean die is obtained.
