[0025] like Figures 1-4 As shown, an open-type long-stroke press with a deep-drawing product trimming structure includes a body 1, an operating unit and a base 13 supporting the body 1.

[0026] In this embodiment, an open cavity in which a pressing plate 3 and a mold plate 2 are installed is provided in front of the fuselage 1 , and the open cavity is configured as a hollow C-shape, wherein the pressing plate 3 is placed above the mold plate 2 .

[0027] Furthermore, the pressing plate 3 is provided with a plurality of pressing sheets 31 , and each pressing sheet 31 is provided with pressing grooves 32 adjacent to each other on both sides, and the shape of the pressing grooves 32 is set to be T-shaped.

[0028] The mold plate 2 is provided with a plurality of first mold grooves 21 and second mold grooves 22. The first mold grooves 21 are provided with a plurality of through holes. The bottom of the mold plate 2 is connected to the hollow opening cavity. Moreover, the shape of the second mold groove 22 is provided with the same T-shape as the pressing groove 32. The difference is that the second mold groove 22 is provided with an inverted T-shape.

[0029] Furthermore, the operating unit includes a first operating platform 11 and a second operating platform 12. The first operating platform 11 is provided with a connecting arm connected to the fuselage 1 and is placed on the right side of the fuselage 1. The second operating platform 12 is placed in the middle position of the fuselage 1, and there is a distance between the second operating platform 12 and the fuselage 1.

[0030] The first operating console 11 and the second operating console 12 are both provided with a plurality of buttons, and the same buttons are also provided between the two, such as an emergency stop button, an operation button, etc.

[0031] Different from the first operating console 11, which is provided with a start switch and a key inserted therein, the second operating console 12 is more operable and is provided with a slider button and a pedal button, wherein the pedal button can be operated by hand or foot.

[0032] When the first operating platform 11 starts the fuselage 1 by the key, and the pressing plate 3 is controlled by the first operating platform 11 or the second operating platform 12 to perform the extrusion operation, the product to be processed is squeezed into the first mold groove 21 or the second mold groove 22 to complete the deformation. During the rising process, the pressing plate 3 is squeezed by the pressing groove 32 provided on the pressing plate 3 to squeeze out the excess scraps to complete the trimming of the product.

[0033] In this embodiment, a piston 16 and a slider 17 for controlling the lifting of the pressure plate 3 are further provided inside the body 1 , and the piston 16 and the slider 17 are placed above the pressure plate 3 .

[0034] Among them, a number of symmetrically arranged columns are provided between the piston 16 and the slider 17 and the pressure plate 3.

[0035] Furthermore, the pistons 16 are symmetrically placed on both sides of the pressure plate 3 , and the slider 17 is placed at the center of the pressure plate 3 .

[0036] The piston 16 on the right side is connected to a display 33, which is used to adjust the slider, control the closed height display, and control the two-way stroke display.

[0037] Furthermore, the slider 17 is provided with a connecting rod 18 connected to the cylinder 4 provided on the top of the fuselage 1 .

[0038] Exhaust valves 41 are symmetrically arranged on both sides of the cylinder 4 .

The motor 6 is placed on the left side of the flywheel 7, and the crossbeam 9 is also placed on the top of the fuselage 1, on the right side of the cylinder 4.

[0040] In order to facilitate the installation and subsequent maintenance of the motor 6 and the flywheel 7, a ladder 15 is provided on the back of the fuselage 1, and a railing is installed at the accommodating cavity to prevent accidents caused by installation or maintenance.

[0041] The crossbeam 9 is cylindrical in shape and is fixedly connected to the fuselage 1 via mounting plates on both sides.

[0042] The crossbeam 9 is used to fix the fuselage 1 to prevent the fuselage 1 from tilting forward due to weight imbalance.

[0043] Furthermore, a distribution box 5 and a box body 8 are provided on the right side of the fuselage 1 , and the box body 8 is placed above the distribution box 5 .

[0044] The distribution box 5 is of a normally closed type, and the box body 8 is provided with a plurality of hollow grid panels.
