Detailed Embodiments

[0026] Next, in combination with the accompanying drawings in the embodiments of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0027] Please refer to Figures 1 - 3 , a precision forming device for hardware products in this embodiment includes a base 1. The upper end of the base 1 is fixedly connected with a mounting frame 2. The upper end of the mounting frame 2 is fixedly connected with a hydraulic cylinder 3 that penetrates through the mounting frame 2 at one end. The output end of the hydraulic cylinder 3 is fixedly connected with a connecting plate 4. The upper end of the base 1 is fixedly connected with a mounting seat 7.

[0028] A upper die assembly 5 for forming stamping is arranged on the connecting plate 4. The upper die assembly 5 includes a cross bar 53. A perforation 52 is formed inside the connecting plate 4. The lower end of the connecting plate 4 is provided with an upper die 54. The cross bar 53 is fixedly connected inside the perforation 52. A support block 56 that extends to the inside of the upper die 54 at one end is slidably connected to the outside of the cross bar 53. A rotating screw 51 that penetrates through the support block 56 and extends to the outside of the connecting plate 4 at one end is rotatably connected to the inside of the perforation 52. A pressing block 55 that extends to the inside of the upper die 54 at one end is fixedly connected to the inside of the support block 56.

[0029] In this embodiment, since the rotating screw 53 drives the pressing block 55 on the support block 56 to separate from the upper die 54, the upper die 54 can be disassembled. Conversely, the upper die 54 can be fixedly installed.

[0030] Among them, the number of perforations 52 is two. The two perforations 52 are symmetrically distributed on the connecting plate 4. One end of the rotating screw 51 is rotatably connected to the inside of the left perforation 52. The other end of the rotating screw 51 is located outside the connecting plate 4, so that the rotating rotating screw 51 can drive the support block 56 to reciprocate horizontally in the perforation 53.

[0031] In addition, a first threaded hole located outside the rotating screw 51 is formed inside the support block 56. The first threaded hole is matched with the thread on the outside of the rotating screw 51. A connecting groove located outside the support block 56 is formed at the upper end of the upper die 54, so that the lower end of the support block 56 can extend into the upper die 54.

[0032] Secondly, a limiting groove that is communicated with the connecting groove at one end and is located outside the pressing block 55 is formed inside the upper die 54. A limiting rod 9 that extends to the inside of the mounting seat 7 at one end is fixedly connected to the lower end of the connecting plate 4. The upper die 54 is limited and fixed by the pressing block 55 that extends into the upper die 54.

[0033] Please refer toFigures 2 - 3 In this embodiment, a lower die assembly 8 for forming stamping is provided on the mounting base 7. The lower die assembly 8 includes a lower die 810 whose one end is slidably connected to the inner side of the mounting base 7. A connecting block 81 is fixedly connected to the lower end of the lower die 810. One end of an adjusting screw 82 is rotatably connected to the inner side of the mounting base 7 and extends through and to its outer side. A support frame 88 is threadedly connected to the outer side of the adjusting screw 82. A vertical rod 86 is slidably connected to the inner side of the support frame 88. A fixing block 84 is fixedly connected to the upper end of the vertical rod 86. A limiting block 83 whose one end extends to the inner side of the connecting block 81 is fixedly connected to the upper end of the fixing block 84. A telescopic rod 89 is fixedly connected between the inner side of the support frame 88 and the inner side of the mounting base 7. The telescopic rod 89 is composed of a sleeve bin and a sliding rod. The sliding rod is slidably connected to the inner side of the sleeve bin. One end of the sliding rod located outside the sleeve bin is fixedly connected to the support frame 88. One end of the sleeve bin is fixedly connected to the inner side of the mounting base 7. A spring 85 is placed between the fixing block 84 and the support frame 88.

[0034] In this embodiment, by rotating the adjusting screw 82 to drive the limiting block 83 to separate from the connecting block 81, the lower die 810 can be disassembled and replaced. On the contrary, the lower die 810 can be fixed in the mounting base 7, so that both the upper die 54 and the lower die 810 are convenient to disassemble and replace, adapting to the stamping processing of different workpieces and improving the convenience of using the whole equipment.

[0035] Among them, a second threaded hole located outside the adjusting screw 82 is opened on the inner wall of the support frame 88. The second threaded hole matches the thread on the outer side of the adjusting screw 82, so that the rotating adjusting screw 82 can drive the support frames 88 on both sides to move towards the closer or farther side.

[0036] In addition, both the connecting block 81 and the limiting block 83 are L-shaped. Magnet blocks 87 are embedded on the outer side of the vertical rod 86 and the inner side of the support frame 88. Through the magnet blocks 87, the vertical rod 86 can be adsorbed inside the support frame 88 to improve the stability when the spring 85 resets and pushes the fixing block 84.

[0037] It should be noted that the threads on the outer sides of the rotating screw 51 and the adjusting screw 82 are both in two sections, and the two sections of threads are symmetrically distributed.

[0038] Secondly, a limiting component 6 for blocking and limiting the lower die 810 is arranged on the front surface of the mounting base 7. The limiting component 6 includes a rotating block 61 with one end hinged to the upper end of the base 1. A baffle 64 is hinged to the front surface of the mounting base 7 through a hinge. The upper end of the rotating block 61 is rotatably connected to a sleeve rod 63. A support screw 62 with one end hinged to the baffle 64 is threadedly connected to the inner side of the sleeve rod 63. A threaded hole located outside the support screw 62 is formed in the inner wall of the sleeve rod 63. An installation groove located outside the baffle 64 is formed in the front surface of the mounting base 7. After the baffle 64 on the front surface of the mounting base 7 is pulled by the support screw 62 through rotating the sleeve rod 63, the lower die 810 is exposed, so as to further increase the convenience of disassembling the lower die 810.

[0039] The working principle of the above embodiment is as follows:

[0040] Since the rotating screw 53 drives the abutting block 55 on the support block 56 to separate from the upper die 54, the upper die 54 can be disassembled. On the contrary, the upper die 54 can be fixedly installed. By rotating the adjusting screw 82 to drive the limiting block 83 to separate from the connecting block 81, and after rotating the sleeve rod 63 and pulling it through the support screw 62, and the lower die 810 is exposed, the lower die 810 can be disassembled and replaced. On the contrary, the lower die 810 can be fixed in the mounting base 7, so that both the upper die 54 and the lower die 810 are convenient to disassemble and replace, adapting to the stamping processing of different workpieces and improving the convenience of using the whole equipment. After the lower die 810 is removed, since the vertical rod 86 is slidably connected to the inner side of the support frame 88, the vertical rod 86 can also be pulled out to replace the spring 85 for buffering and resetting, maintaining the reset function of the spring 85. The spring 85 located between the fixed block 84 and the support frame 88 can support and buffer the lower die 810, and the reset spring 85 pushes the lower die 810 to move upward and reset, so as to push the lower die 810 to lift the stamped workpiece, improving the convenience of demoulding, and further improving the convenience of stamping of the whole equipment.
