DETAILED DESCRIPTION

[0033] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0034] Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0035] For example, see Figure 1-6 The present invention provides a technical solution: a high-precision machine tool sheet metal stamping die, including a fixed base 1, and also includes a driving assembly 6, a lower die 2 is fixedly connected to the middle of the top of the fixed base 1, and guide rods 4 are fixedly connected to the four corners of the top of the fixed base 1. An upper die 3 is slidably connected to the outer side of the guide rod 4, and a sheet metal part 5 is arranged on the top of the lower die 2.

[0036] Wherein, the driving component 6 comprises:

[0037] A fixing groove 601 is fixedly connected to the outer side of the lower mold 2, a driving motor 602 is fixedly connected to the front side of the fixing groove 601, the driving motor 602 has an output shaft, a threaded rod 603 is fixedly connected to the output shaft of the driving motor 602, a ball nut pair 604 is threadedly connected to the outer side of the threaded rod 603, and an adjusting frame 605 is fixedly connected to the side of the ball nut pair 604 away from the lower mold 2, and the driving motor 602 can drive the threaded rod 603 to rotate when working.

[0038] It also includes a fixing assembly 7, which consists of an adjusting arm 701, a driving frame 702, a clamping arm plate 703, a rotating connecting block 704, a positioning frame 705 and a rubber clamping block 706.

[0039] The adjusting arm 701 is rotatably connected to the middle part of the adjusting frame 605, the driving frame 702 is rotatably connected to the side of the adjusting arm 701 away from the adjusting frame 605, the clamping arm plate 703 is fixedly connected to the side of the driving frame 702 away from the adjusting arm 701, the rotating connecting block 704 is fixedly connected to the side of the clamping arm plate 703 close to the lower mold 2, the positioning frame 705 is fixedly connected to the top outer side of the lower mold 2, and the rubber clamping block 706 is fixedly connected to the back side of the clamping arm plate 703. The adjusting arm 701 can push the driving frame 702 and the clamping arm plate 703.

[0040] The end of the threaded rod 603 away from the output shaft of the driving motor 602 is fixedly connected to the inner wall of the fixed groove 601. A limiting groove for accommodating the sliding of the adjustment frame 605 is opened in the middle of the side of the fixed groove 601 away from the lower mold 2. The adjustment frame 605 is located inside the limiting groove and can support the threaded rod 603.

[0041] The rotating connection block 704 is rotationally connected to the middle of the positioning frame 705 , and the clamping arm plate 703 is rotationally connected to the positioning frame 705 through the rotating connection block 704 . The clamping arm plate 703 and the rotating connection block 704 can rotate in the middle of the positioning frame 705 .

[0042] When the sheet metal part 5 needs to be installed, the driving motor 602 is controlled to work, so that the driving motor 602 drives the threaded rod 603 to rotate. When the threaded rod 603 rotates, the ball nut pair 604 can move outside the threaded rod 603, so that the ball nut pair 604 moves in a direction away from the rotating connecting block 704, and the clamping arm plate 703 can be opened, so that the sheet metal part 5 can be quickly installed and disassembled.

[0043] The driving motor 602 is controlled to work so that the ball nut pair 604 moves in a direction away from the rotating connecting block 704. At this time, the adjusting frame 605 on the ball nut pair 604 pulls the adjusting arm 701, so that the driving frame 702 is subjected to force, which can make the rotating connecting block 704 on the clamping arm plate 703 rotate in the middle of the positioning frame 705, so that the clamping arm plate 703 can be opened, and then the sheet metal part 5 is placed on the top of the lower mold 2, and then the driving motor 602 is controlled to reverse, so that when the driving motor 602 is reversed, the clamping arm plate 703 can be opened. The positioning frame 705 on the arm plate 703 is inserted into the outside of the sheet metal part 5. At the same time, as the amplitude of the rotation of the clamping arm plate 703 increases, the positioning frame 705 on the clamping arm plate 703 can squeeze the outside of the sheet metal part 5. Since the rubber clamping block 706 is made of rubber, when the rubber clamping block 706 is used to squeeze the outside of the sheet metal part 5, the sheet metal part 5 can be fixed to prevent the stamping force generated when the upper mold 3 and the lower mold 2 are closed from causing the sheet metal part 5 to shake, so that the device can fix the sheet metal part 5 when in use.

[0044] When the sheet metal part 5 is moved, the driving motor 602 is controlled to work so that the rubber clamping block 706 on the clamping arm plate 703 is separated from the edge of the sheet metal part 5. At the same time, the rubber clamping block 706 can limit the moving direction and moving space of the sheet metal part 5 to prevent the sheet metal part 5 from being difficult to move due to the large squeezing force of the rubber clamping block 706 when the sheet metal part 5 is moved to load.

[0045] For example 2, please refer to Figure 1-9 On the basis of the first embodiment, the present invention provides a technical solution: it also includes a uniform cloth component 8, which is composed of a fixed plate 801, a water bag 802, an extrusion piece 803, a spring connecting tube 804, a lifting box 805, a spring 806, a lifting piston plate 807, a lifting adjustment frame 808, a rotating roller 809, a self-cleaning box 810 and a cleaning rod 811.

[0046] The fixed plate 801 is fixedly connected to the bottom of the fixed groove 601, the water bag 802 is fixedly connected to the front of the fixed plate 801, the extrusion piece 803 is fixedly connected to the bottom of the ball nut pair 604, the spring connecting tube 804 is fixedly connected to the bottom of the water bag 802, the lifting box 805 is fixedly connected to the middle part of the outer side of the lower mold 2, the spring 806 is fixedly connected to the inner bottom of the lifting box 805, the lifting piston plate 807 is fixedly connected to the top of the spring 806, the lifting adjustment frame 808 is fixedly connected to the top of the lifting piston plate 807, the rotating roller 809 is rotatably connected to the inner side of the lifting adjustment frame 808, the self-cleaning box 810 is fixedly connected to the middle of the top of the lifting box 805, and the cleaning rod 811 is fixedly connected to the inner walls on the left and right sides of the self-cleaning box 810. When the lifting piston plate 807 rises, it can drive the lifting adjustment frame 808 and the rotating roller 809 to rise.

[0047] A fixing groove is opened at the bottom of the fixing groove 601, and the top of the extrusion piece 803 passes through the fixing groove and extends into the fixing groove 601 to be fixedly connected to the bottom of the ball nut pair 604. The extrusion piece 803 can slide in the fixing groove, and the extrusion piece 803 can squeeze the water bag 802 when moving.

[0048] One end of the spring connecting tube 804 away from the water bag 802 is fixedly connected to the bottom of the lifting box 805. The water bag 802 is connected to the bottom of the lifting box 805 through the spring connecting tube 804. The water bag 802 is filled with water.

[0049] A storage groove is provided in the middle of the top of the front and back of the self-cleaning box 810, and the rotating roller 809 can move down into the storage groove.

[0050] When the driving motor 602 is controlled to work, the clamping arm plate 703 moves to the outside of the sheet metal part 5. At this time, the ball nut pair 604 drives the extrusion part 803 to move, so that the extrusion part 803 squeezes the water bag 802, and the water in the water bag 802 is introduced into the lifting box 805 through the spring connecting tube 804, so that the water pressure at the bottom of the lifting box 805 increases, and at the same time the spring 806 is stretched, so that the lifting piston plate 807 drives the lifting adjustment frame 808 to rise. At this time, the rotating roller 809 moves upward from the inside of the self-cleaning box 810 and is exposed, so that the rotating roller 809 can contact the bottom of the sheet metal part 5. At this time, the rotating roller 809 can evenly apply the lubricating oil on the bottom of the sheet metal part 5, and can avoid excessive lubricating oil at the bottom of the sheet metal part 5 when the sheet metal part 5 moves to the stamping position, which may cause displacement of the sheet metal part 5 during subsequent stamping.
