Example Embodiment

[0016] The following describes the specific implementation of the present invention in further detail through the description of the embodiments with reference to the accompanying drawings. The purpose is to help those skilled in the art have a more complete, accurate and in-depth understanding of the concept and technical solutions of the present invention, and Contribute to its implementation.
[0017] Such as Figure 1 to Figure 2 As shown, the present invention is an integral forming stamping die, which realizes mechanical automatic demoulding after the integral forming of small aluminum plate parts by stamping, improving the demolding efficiency and reducing the labor intensity of workers.
[0018] Specifically, such as Figure 1 to Figure 2 As shown, it includes a support 1, a stamping platform 2, a discharge assembly 3, a cushion block 4, a door frame 5, a forming base plate 6, a door frame 2 7 and a hydraulic cylinder 8. The stamping platform 2 and the upper end of the support 1 Fixed connection, the punching platform 2 is provided with a counterbore 20 in the middle, the discharging assembly 3 is composed of a discharging barrel 30, a spring 31 and a push rod 32, and the discharging barrel 30 is connected to the counterbore 20 by bolts. Connected, and the upper end of the discharge cylinder 30 is flush with the upper end surface of the punching platform 2, the discharge cylinder 30 is provided with a cylindrical hole 30-1, the spring 31 is arranged in the cylindrical hole 30-1, and the push The lower end of the material rod 32 is provided with a slider 32-1. The lower end of the spring 31 is in contact with the bottom of the cylindrical hole 30-1. The upper end of the spring 31 is in contact with the lower end of the slider 32-1. The block 32-1 is slidably connected with the cylindrical hole 30-1, the cushion block 4 is fixedly connected with the stamping platform 2, the door frame 5 is provided with two, and they are respectively fixedly connected with the cushion block 4, and the forming base The plate 6 is hinged with the door frame 5, the lower end of the door frame 2 7 is connected with the stamping platform 2 by bolts, the hydraulic cylinder 8 and the door frame 2 7 are connected by bolts, and the piston rod end of the hydraulic cylinder 8 is provided with There is a punch 80.
[0019] Such as figure 1 As shown, the inner diameter of the cylindrical hole 30-1 is the same as the outer diameter of the slider 32-1.
[0020] Such as figure 1 As shown, the middle of the spacer block 4 is provided with a second cylindrical hole 40, and the upper end of the push rod 32 passes through the second cylindrical hole 40. The inner diameter of the second cylindrical hole 40 is smaller than the inner diameter of the first cylindrical hole 30-1.
[0021] Such as figure 1 As shown, the push rod 32 has a hemispherical structure.
[0022] The following uses specific examples to illustrate specific working methods:
[0023] In the one-piece stamping die, the aluminum plate to be stamped and formed is placed above the forming base plate 6 between the two door frames 5, and then the hydraulic cylinder 8 is activated, and the stamping head 80 at the end of the piston rod of the hydraulic cylinder 8 moves downward. On the aluminum plate to be stamped and formed, then as the stamping head 80 moves down, the forming base plate 6 rotates around the axis hinged to the door frame 5, and then the forming base plate 6 presses down the push rod 32, the push rod The slider 32-1 in the lower part of 32 moves down along the cylindrical hole 30-1, and the slider 32-1 further compresses the spring 31 until the lower end of the push rod 32 contacts the bottom of the cylindrical hole 30-1. When the forming base plate 6 rotates to a horizontal state, the stamping operation of the aluminum plate to be stamped and formed is completed, and then the piston rod of the hydraulic cylinder 8 moves upward with the stamping head 80. At this time, the elastic restoring force of the spring 31 Downward, the elastic restoring force of the spring 31 acts on the slider 32-1 to move the push rod 32 upward, and again push the forming base plate 6 to rotate in the opposite direction around the axis hinged to the door frame 5, and the stamping is formed The small aluminum plates are ejected, which realizes the mechanical automatic demoulding of the small aluminum plates after stamping and integral forming, which improves the demolding efficiency and reduces the labor intensity of the workers.
[0024] The inner diameter of the cylindrical hole 30-1 is the same as the outer diameter of the slider 32-1, which ensures the stability of the up and down movement of the push rod 32 and the reliability of demolding.
[0025] A second cylindrical hole 40 is provided in the middle of the spacer block 4, and the upper end of the push rod 32 passes through the second cylindrical hole 40. The inner diameter of the second cylindrical hole 40 is smaller than the inner diameter of the cylindrical hole 30-1 to ensure the spacer block 4 The lower end of the lower end limits the upward movement of the slider 32-1 to prevent the lower slider 32-1 of the push rod 32 from leaving the cylindrical hole 30-1.
[0026] The push rod 32 has a hemispherical structure, so that the lower end of the forming base plate 6 is always in point contact with the upper end of the push rod 32, reducing friction loss.
[0027] The present invention has been exemplarily described above in conjunction with the accompanying drawings. Obviously, the specific implementation of the present invention is not limited by the above-mentioned manners, as long as various insubstantial improvements are made by adopting the method concept and technical solutions of the present invention; or After improvement, directly applying the above-mentioned concept and technical scheme of the present invention to other occasions are all within the protection scope of the present invention.
