A stamping device with a safety protection function includes: a bottom plate 1, and a support frame 11 is fixedly installed on the top of the bottom plate 1;

[0029] A hydraulic telescopic rod 2, the hydraulic telescopic rod 2 is fixedly installed on the top of the support frame 11, a movable end of the hydraulic telescopic rod 2 is fixedly installed with an upper die 21, both ends of the top of the upper die 21 are fixedly installed with side plates 22, a slide rod 25 is slidably connected inside the side plates 22, a limit plate 27 is arranged at the top of the slide rod 25, a pressing plate 24 is fixedly installed at the bottom of the slide rod 25, a first spring 26 is arranged at the top of the pressing plate 24, and the first spring 26 is arranged on the outer side surface of the slide rod 25;

[0030] A protective frame 3, the top of the protective frame 3 is fixedly installed on the top of the bottom plate 1, limit rings 34 are fixedly installed around the bottom of the inner side surface of the protective frame 3, a fixed pipe 36 is arranged on the inner side surface of the limit ring 34, an extension rod 37 is slidably connected to the top of the inner side surface of the fixed pipe 36, a positioning plate 38 is fixedly installed at the bottom of the extension rod 37, and a second spring 39 is arranged at the bottom of the positioning plate 38;

[0031] A moving plate 4, the moving plate 4 is fixedly installed on the top of the extension rod 37, mounting plates 41 are fixedly installed at both ends of the top of the moving plate 4, a positioning screw 42 is threadedly connected inside the mounting plate 41, a lower die 43 is arranged on the top of the moving plate 4, and one end of the positioning screw 42 abuts against the end face of the lower die 43.

[0032] The limit plate 27 is arranged at the top of the side plate 22, limit rods 23 are arranged on both sides of the slide rod 25, the bottom of the limit rod 23 is fixedly installed on the top of the pressing plate 24, and the limit rod 23 is slidably connected inside the side plate 22.

[0033] When moving up and down through the pressing plate 24, the limit rod 23 slides inside the side plate 22. In this way, when in use, the pressing plate 24 can be limited, and the stability of the pressing plate 24 moving up and down can be increased.

[0034] A door body 31 is rotatably connected to the front of the protective frame 3, and an observation window 32 is fixedly installed on the front of the door body 31.

[0035] By providing a door body 31 on the front of the protective frame 31, it is convenient for users to maintain the fixed pipe 36, the extension rod 37 and the second spring 39 on the inner side of the protective frame 3, and through the observation window 32, it is convenient to observe the stamping situation.

[0036] One side of the limiting ring 34 is internally threadedly connected with a locking screw 35, and one end of the locking screw 35 abuts against one side of the fixed pipe 36.

[0037] When the second spring 39 needs to be replaced, the user can rotate the locking screw 35 to make one end of the locking screw 35 away from the fixed pipe 36, and then move the fixed pipe 36 upward, so as to facilitate the user to replace the second spring 39.

[0038] The positioning plate 38 and the second spring 39 are both arranged on the inner side surface of the fixed pipe 36.

[0039] Chute grooves 33 are provided on both sides of the protective frame 3.

[0040] The working principle of a stamping device with a safety protection function provided by the present utility model is as follows:

[0041] When in use, place the stamping part to be stamped on the top of the lower die 43. Then the user starts the hydraulic telescopic rod 2, and the extension of the hydraulic telescopic rod 2 drives the upper die 21 to move downward, so that the upper die 21 drives the side plate 22 and the pressing plate 24 to move downward, so that the pressing plate 24 presses on the top of the stamping part to limit the stamping part. At this time, since the elasticity of the first spring 26 is greater than the elasticity of the four second springs 39, the moving plate 4 can be moved downward until the bottom of the moving plate 4 presses on the top of the fixed pipe 36. At this time, the moving plate 4 and the lower die 43 are on the inner side surface of the protective frame 3. At this time, the first spring 26 will contract, so that the upper die 21 presses on the top of the stamping part to stamp the stamping part. After stamping, the hydraulic telescopic rod 2 moves upward until the pressing plate 24 is away from the stamping part. At this time, the user can take out the stamping part.

[0042] Compared with the related art, a stamping device with a safety protection function provided by the present utility model has the following beneficial effects:

[0043] The hydraulic telescopic rod 2 drives the upper die 21 to move downward, and then through the cooperation of the side plate 22, the slide rod 25 and the first spring 26, the pressing plate 24 is pressed on the top of the stamping part to automatically limit the stamping part, eliminating the need for manual operation by the user, thus reducing the operation steps and increasing the work efficiency. Moreover, the lower die 43 is moved to the inner side of the protection frame 2 by the pressing plate 24, and then the stamping part is stamped, thereby playing a role in protecting during stamping and increasing the safety.

[0044] Second Embodiment

[0046] Specifically, the difference of a stamping device with a safety protection function provided in the second embodiment of the present application is that for a stamping device with a safety protection function, a threaded hole 5 is opened at the top of the slide rod 25, a threaded rod 51 is fixedly installed at the bottom of the threaded hole 5, and the top of the threaded rod 51 is fixedly installed at the bottom of the limiting plate 27.

[0047] The working principle of a stamping device with a safety protection function provided by the present utility model is as follows:

[0048] After long-term use, when the elasticity of the first spring 26 decreases, the user can rotate the limiting plate 27, so that the limiting plate 27 drives the bottom of the threaded rod 51 to be threadedly connected inside the threaded hole 5, thereby disassembling the limiting plate 27, and then the user can disassemble and replace the first spring 26.

[0049] Compared with the related art, a stamping device with a safety protection function provided by the present utility model has the following beneficial effects:

[0050] Through the cooperation of structures such as the threaded hole 5 and the threaded rod 51, during use, the threaded rod 51 is threadedly connected inside the threaded hole 5, so that it is convenient for the user to disassemble the limiting plate 27 from the top of the slide rod 25 and then replace the first spring 26.
