Detailed implementation

[0021] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be described in detail below in conjunction with the accompanying drawings. The description in this part is only exemplary and explanatory, and should not have any restrictive effect on the protection scope of the present invention. Embodiment

[0022] As Figures 1-5 shown, an automatic precision stamping die for automobile longitudinal beams includes a base 1, a top plate 2 located at the top of the base 1, and a lower die 11 fixedly arranged at the top of the base 1. The base 1 and the top plate 2 are connected by a plurality of electric telescopic rods 12. An upper die 3 is arranged below the top plate 2, and the upper die 3 and the top plate 2 are connected by a connection assembly 4.

[0023] The connection assembly 4 includes an installation groove opened in the top plate 2 for fitting the upper die 3. The installation groove penetrates the top and bottom of the top plate 2. A mounting plate 31 is fixedly arranged at the top of the upper die 3. A placement groove for placing the mounting plate 31 is opened at the top of the top plate 2. A plurality of guide rods 45 are fixedly arranged on both the left and right sides of the top plate 2. A slide block 451 is slidably arranged on the surface of the guide rod 45. A pressing plate 44 for pressing the mounting plate 31 is slidably arranged on the top of the top plate 2. The pressing plate 44 and the slide block 451 are connected by a second connection plate 452.

[0024] When it is necessary to replace the upper die, first move a plurality of slide blocks 451 so that the plurality of slide blocks 451 gradually move away from the top plate 2, thereby driving the second connection plate 452 to move, and then driving the pressing plate 44 to move until the bottom end of the pressing plate 44 is separated from the top end of the mounting plate 31. At this time, the limit on the mounting plate 31 is lost, and the mounting plate 31 can be removed, and then the upper die can be removed. At this time, it can be replaced.

[0025] A mounting seat 41 is fixedly arranged at the rear side of the top of the top plate 2. A groove is opened at the front side of the mounting seat 41. A threaded rod 42 is rotatably arranged in the groove. Both ends of the threaded rod 42 are threadedly connected with threaded blocks 43. Threaded sections with opposite helix directions are opened at both ends of the threaded rod 42. The two threaded blocks 43 are respectively connected to the two pressing plates 44 through first connection plates 431. The threaded rod 42 is driven by a motor.

[0026] When it is necessary to move the pressing plate 44, drive the motor, which in turn drives the threaded rod 42 to rotate, which in turn drives the threaded block 43 to move, which in turn drives the first connecting plate 431 to move, which in turn drives the pressing plate 44 to move.

[0027] Two positioning blocks 21 are fixedly arranged at the top of the placing groove. Positioning holes for cooperating with the positioning blocks 21 are formed in the mounting plate 31, and the positioning holes penetrate through the top and bottom of the mounting plate 31.

[0028] A handle 32 is fixedly arranged at the top of the mounting plate 31.

[0029] Working principle: When it is necessary to replace the upper mold, first move a plurality of sliders 451 so that the plurality of sliders 451 gradually move away from the top plate 2, which in turn drives the second connecting plate 452 to move, which in turn drives the pressing plate 44 to move until the bottom end of the pressing plate 44 is separated from the top end of the mounting plate 31. At this time, the limit on the mounting plate 31 is lost, and the mounting plate 31 can be removed, and then the upper mold can be removed. At this time, it can be replaced.
