DETAILED DESCRIPTION
[0030] The technical solutions in the embodiments of the utility model will be apparently and completely described in combination with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by the person skilled in the art without creative labor belong to the protection scope of the utility model.
[0031] Reference Figures 1-3 A flanging stamping forming die is used in cooperation with a punch, comprising a fixed block 1, two limiting blocks 2, two stamping plates 3, a placing table 4, an elastic buffer assembly 5 and a stamping block 6. The fixed block 1 is a basic supporting component of the whole die and can be connected with the working platform of the punch through bolts to provide a stable platform for the installation of other components. The two limiting blocks 2 are symmetrically arranged on the fixed block 1 and can limit the movement of the iron box body to ensure the position accuracy of the iron box body during the stamping process and prevent the iron box body from deviating to improve the precision of the stamping forming of the iron box body. The two stamping plates 3 are symmetrically arranged on the fixed block 1 and are arranged between the two limiting blocks 2. The stamping plate 3 is arranged on the side of the limiting block 2 close to each other. The flanging of the iron box body is realized by the direct contact of the two end faces of the iron box body with the stamping plate 3 and the application of force. The placing table 4 is arranged between the two stamping plates 3 and is used for placing the iron box body to be processed. The elastic buffer assembly 5 is arranged between the placing table 4 and the fixed block 1. The buffer force generated by the elastic buffer assembly 5 can reduce the influence of the stamping force on the iron box body and avoid the tearing or deformation of the iron box body. The stamping block 6 is arranged above the placing table 4 and is adapted to the top surface of the placing table 4. The stamping block 6 can be fixed on the punch through bolts and can stamp the iron box body placed on the placing table 4 under the drive of the punch in cooperation with the stamping plate 3 to realize the flanging of the iron box body.
[0032] In some embodiments, the top of the stamping plate 3 can be lower than the top of the limiting block 2 to limit and constrain the two sides of the iron box body to realize the accurate placement of the iron box body and improve the stamping precision.
[0033] In some embodiments, the length of the stamping block 6 can be equal to the length of the placement table 4, ensuring that the stamping block 6 covers the entire area outside the flanging area of the iron box body when stamping, improving the uniformity of the iron box body stamping, improving the consistency of the flanging, and avoiding the bending of the flanging connection, improving the integrity of the iron box body shape.
[0034] In some embodiments, the elastic buffer assembly 5 includes a plurality of sliding grooves 51, a sliding rod 52, and a buffer spring 53. The sliding grooves 51 pass through the fixed block 1, the sliding rod 52 is slidingly arranged in the sliding grooves 51, and the buffer spring 53 is arranged between the sliding rod 52 and the sliding grooves 51.
[0035] When the stamping block 6 stamps the iron box body on the placement table 4, the placement table 4 will move downward, driving the sliding rod 52 to slide in the sliding groove 51, and at the same time, the buffer spring 53 is compressed, generating a buffer force, thereby reducing the impact of the stamping force on the iron box body, and avoiding tearing or deformation of the iron box body.
[0036] In some embodiments, the elastic buffer assembly 5 further includes a limiting groove 54 and a limiting ring 55. The limiting groove 54 is coaxially arranged in the middle of the sliding groove 51, the limiting ring 55 is coaxially arranged on the sliding rod 52, and the buffer spring 53 is arranged between the limiting ring 55 and the inner bottom wall of the limiting groove 54. The arrangement of the limiting groove 54 and the limiting ring 55 can limit the sliding range of the sliding rod 52, prevent the sliding rod 52 from coming out of the sliding groove 51, and at the same time, ensure that the buffer spring 53 remains stable during compression and stretching, improving the reliability of the elastic buffer assembly 5.
[0037] In some embodiments, the sliding groove 51 can be four, and the four sliding grooves 51 are arranged in a matrix on the fixed block 1, which can ensure that the placement table 4 can uniformly transmit the force to each sliding rod 52 when subjected to the stamping force, so that the elastic buffer assembly 5 can provide uniform buffer force, improving the stability of the stamping.
[0038] In some embodiments, the placement table 4 includes a table body 41, a plurality of connecting holes 42, a threaded hole 43, and a connecting screw 44. The table body 41 is arranged above the fixed block 1, and the table body 41 can slide between the two stamping plates 3. The table body 41 is gap-fitted with the two stamping plates 3, which can reduce the gap between the table body 41 and the stamping plates 3, thereby reducing the deformation of the iron box body during flanging. The connecting holes 42 are arranged at the bottom of the table body 41 and are inserted and fitted with the sliding rods 52. The threaded holes 43 are arranged at the top of the table body 41 and are coaxially connected with the connecting holes 42. The connecting screw 44 is threadedly connected with the threaded holes 43 and is threadedly connected with the sliding rods 52. Through the connecting holes 42 and the connecting screw 44, the placement table 4 and the sliding rods 52 can be firmly connected together, ensuring that the placement table 4 will not loosen during stamping.
[0039] In some embodiments, the placing table 4 further comprises a square groove 45 arranged on the top of the table body 41, which can reduce the weight of the placing table 4, and at the same time, the bottom of the iron box body can be embedded in the square groove 45 during the stamping process, thereby increasing the stability of the iron box body on the placing table 4 and preventing displacement of the iron box body during stamping.
[0040] The specific working principle is as follows:
[0041] When using the flanging stamping forming die, first, the iron box body is placed on the placing table 4, and the two sides of the iron box body are respectively located between the two stamping plates 3, so that the position of the iron box body is accurately fixed. Then, the punch is started to drive the stamping block 6 to move downward. When the stamping block 6 contacts the iron box body, a downward pressure is applied to the iron box body.
[0042] With the continuous downward pressing of the stamping block 6, the placing table 4 moves downward under the action of the stamping force, driving the sliding rod 52 to slide in the sliding groove 51, and the buffer spring 53 is compressed to generate a buffer force, thereby reducing the influence of the stamping force on the iron box body and avoiding tearing or deformation of the iron box body. In this process, the iron box body moves downward under the joint action of the stamping block 6 and the placing table 4, and the two sides of the iron box body will contact the stamping plate 3, which will exert a vertical force on the two sides of the iron box body, thereby making the two sides of the iron box body flange outward to realize the flanging of one side of the iron box body. After the stamping is completed, the punch is raised, and the placing table 4 returns to the initial position under the elastic force of the buffer spring 53, rotates the iron box body by 90° for three times, and repeats the above steps after rotation. After the four edges of the iron box body are flanged, the stamping completed iron box body is taken out to obtain the flanged iron box body.
[0043] The above embodiments are only used to illustrate the technical solutions of the present application, but not to limit them; although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that the technical solutions recorded in the foregoing embodiments can be modified, or some technical features can be replaced by equivalents; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present application.
