Detailed implementation manner

[0023] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0024] Referring to Figures 1-5 , a processing die for connecting workpieces, including a bottom plate 1, a lower die 2 is installed at the upper end of the bottom plate 1, buffer boxes 5 are respectively installed on both sides of the lower die 2, a frame is fixedly connected to the upper end of the bottom plate 1, the frame is connected to an upper die 3 through a telescopic mechanism, the upper die 3 is fitted inside the lower die 2, a plurality of first springs 9 are fixedly connected to the inner bottom of the buffer box 5, and the plurality of first springs 9 are commonly connected to a slide plate 8. Buffer plates 17 are fixedly connected to both outer walls of the upper die 3, the buffer plates 17 are slidably connected inside the buffer box 5, slide bars 11 are slidably connected to the side walls of the buffer box 5, sliders 12 are fixedly connected to the ends of the slide bars 11, both end faces of the sliders 12 are inclined, the outer walls of the buffer plates 17 are in contact with the outer walls of the sliders 12, side plates 10 are fixedly connected to the side walls of the buffer box 5, a siren 6 is installed on the outer wall of the buffer box 5, and a detection mechanism for detecting the fatigue strength of the first spring 9 is installed on the outer wall of the side plate 10;

[0025] During specific use, one of the buffer plate 17 and the slide plate 8 is always in contact with the slider 12, thereby driving the connecting rod 13 to be in contact with the outer wall of the button 14. At this time, the siren 6 is in a silent state. When the elasticity of the first spring 9 drops to a certain extent, the slide plate 8 cannot contact the slider 12 during reset, thereby causing the connecting rod 13 not to contact the button 14. At this time, the siren 6 makes a sound, informing the operator that the first spring 9 is fatigued, so as to reduce the risk of die damage.

[0026] The detection mechanism includes a connecting rod 13 fixedly connected to the outer wall of the slider 12. A button 14 is installed on the outer wall of the side plate 10. The button 14 is electrically connected to the siren 6. The end of the connecting rod 13 contacts the outer wall of the button 14. The telescopic mechanism includes a hydraulic cylinder 4 fixedly connected to the upper end of the frame. The telescopic end of the hydraulic cylinder 4 is fixedly connected to the upper die 3. The sliding rod 11 is fixedly connected to the slider 12. The sliding rod 11 is slidably connected to the outer wall of the side plate 10. The outer wall of the side plate 10 is L-shaped. The sliding plate 8 is slidably connected in the buffer box 5. The upper end surface of the sliding plate 8 contacts the outer wall of the slider 12. A limiting frame 7 is fixedly connected to the inner wall of the buffer box 5. The limiting frame 7 is located directly above the slider 12. A limiting block 15 is fixedly connected to the end of the sliding rod 11. The radius of the limiting block 15 is larger than the radius of the sliding rod 11. A second spring 16 is sleeved on the outer wall of the sliding rod 11. One end of the second spring 16 is fixedly connected to the side plate 10, and the other end of the second spring 16 is fixedly connected to the limiting block 15. The function of the provided second spring 16 is to drive the slider 12 to reset.

[0027] In the present utility model, when the device is specifically used: The hydraulic cylinder 4 is started, and the upper die 3 is driven to move downward through its telescopic end, so that the upper die 3 fits with the lower die 2. When the upper die 3 slides, the buffer plate 17 is pressed down along with the movement of the upper die 3 and contacts the slider 12 and the sliding plate 8. During this process, the first spring 9 provides a reaction force to ensure the normal operation of the buffering function. The sliding of the slider 12 can drive the sliding rod 11 to slide to one side, driving the connecting rod 13 to abut against the outer wall of the button 14. After the processing is completed, the first spring 9 resets, driving the sliding plate 8 to slide upward, synchronously driving the slider 12 to slide to one side, so that the connecting rod 13 abuts against the outer wall of the button 14.

[0028] During long-term or high-frequency use, the elasticity of the first spring 9 will gradually decrease. When the elasticity of the first spring 9 decreases to a certain extent, the sliding plate 8 cannot contact the slider 12 during the reset process, so that the sliding rod 11 cannot press the button 14 through the connecting rod 13. At this time, the circuit detects that the connecting rod 13 fails to press the button 14, triggering the siren 6 to emit a sound, prompting the operator that the first spring 9 is fatigued and needs to be replaced in time to avoid the failure of the buffering function and the damage of the mold.

[0029] The above is only a preferred specific embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution of the present utility model and its inventive concept, makes equivalent substitutions or changes, and should be covered by the protection scope of the present utility model.
