[0019] The utility model is described in detail below in connection with the drawings and examples.
[0020] The high -efficient stamping equipment, likeFigures 1-4 As shown, including the body, the body is fixedly connected with the lower die seat 2, the lower die seat 2 is provided with the lower die seat 2, the body is slidably connected with the upper die seat 1, the upper die seat 1 is provided with the upper die seat 1 corresponding to the lower die 3, the outer wall of the upper die 4 is provided with the sliding cavity 5, the sliding cavity 5 is slidably connected with the sliding rod 6 which is opposite to the lower die seat 2, the cross section shape of the sliding rod 6 is L-shaped, the side of the sliding rod 6 away from the upper die 4 and close to the lower die 3 is provided with an inclined surface, the distance between the inclined surface and the thickening plate 7 gradually decreases from the height direction of the sliding rod 6, the top surface of the sliding cavity 5 is provided with a sliding groove, the sliding rod 6 slides in the sliding groove along the width direction of the upper die 4, in the initial state, if the horizontal bottom surface of the sliding rod 6 is opposite to the top surface of the lower die seat 2, the sliding rod 6 is only subjected to the pressure in the height direction and will not move in the sliding groove, after the distance between the upper die 4 and the lower die 3 increases, the inclined surface of the sliding rod 6 will be opposite to the inner wall of the lower die 3, at this time, the inner wall of the lower die 3 will exert a thrust force on the inclined surface of the sliding rod 6, at this time, the sliding rod 6 will slide in the sliding groove towards the inner wall of the sliding cavity 5, the distance between the bottom surface of the sliding rod 6 and the bottom surface of the upper die 4 is equal to the depth of the lower die 3, and since the sliding rod 6 only moves along the width direction of the upper die 4, the sliding rod 6 will not extend into the lower die 3, thereby affecting the stamping quality.
[0021] As shown in Figure 1 , Figure 2 and Figure 4 , the inner wall of the sliding cavity 5 is slidably connected with the thickening plate 7 which is perpendicular to the sliding direction of the sliding rod 6, the setting of the thickening plate 7 can fill the gap added between the upper die 4 and the lower die 3, the thickening plate 7 is located on the side of the upper die seat 1 away from the lower die seat 2, and the distance between the bottom surface of the thickening plate 7 and the upper die 4 is the same as the depth of the lower die 3, so that it can be ensured that the thickening plate 7 will not extend into the lower die 3 and affect the normal stamping process when the stamping equipment is in normal use, if the sliding rod 6 slides, the thickening plate 7 will slide downward along the height direction of the upper die 4, when the thickening plate 7 slides to the bottom surface, the bottom surface of the thickening plate 7 and the bottom surface of the upper die 4 are located in the same plane, thereby reducing the large gap formed between the upper die 4 and the lower die 3, avoiding the waste of time due to the replacement of the upper die 4 and the lower die 3 caused by the gap, and improving the stamping efficiency of the equipment, the width of the thickening plate 7 is the same as the width of the upper die 4, ensuring that the upper die 4 still has good stamping quality after the thickening plate 7 is added, the side of the thickening plate 7 away from the upper die seat 1 and the side of the sliding rod 6 close to the upper die seat 1 form a sliding space, ensuring that the sliding rod 6 can slide in the sliding space after being subjected to the thrust force of the lower die 3.
[0022] As shown in Figures 1-5As shown, the sliding cavity 5 is provided with a rotating groove 10 away from one side of the sliding rod 6, and the inclined push rod 8 is rotatably connected in the rotating groove 10. The thickening plate 7 is integrally formed with the connecting plate 9 which is vertically arranged on the side close to the upper die seat 1. The bottom surface of the connecting plate 9 abuts against the bottom surface of the rotating groove 10, so as to avoid the thickening plate 7 from sliding downward under the action of gravity. The two ends of the push rod 8 abut against the end surfaces of the sliding rod 6 and the connecting plate 9, respectively. In the initial state, the distance between the abutting end of the push rod 8 and the sliding rod 6 is smaller than the distance between the abutting end of the push rod 8 and the connecting plate 9 and the sliding rod 6. When the sliding rod 6 slides towards the rotating groove 10, one end of the push rod 8 slides along the sliding direction of the sliding rod 6. At this time, the other end of the push rod 8 rotates away from the rotating groove 10, and pushes the connecting plate 9 and the thickening plate 7 to slide together. The bottom surface of the connecting plate 9 slides out of the bottom surface of the rotating groove 10. At this time, the supporting force of the connecting plate 9 disappears, and the thickening plate 7 slides downward under the action of its own gravity. When the thickening plate 7 slides to the bottom surface of the sliding cavity 5, the bottom surface of the thickening plate 7 is located on the same plane as the bottom surface of the upper die 4, so as to ensure the efficiency of the equipment in use, and avoid the time required for replacing the upper die 4 and the lower die 3.
[0023] As shown in the figure, Figures 1-5 The top surface of the sliding cavity 5 is fixedly connected with the telescopic rod, and the other end of the telescopic rod is slidably connected with the top surface of the connecting plate 9. The top surface of the connecting plate 9 is provided with a sliding channel, and one end of the telescopic rod slides on the sliding channel along the width direction of the upper die 4. The telescopic rod provides a supporting effect for the sliding of the connecting plate 9 and the thickening plate 7, and can increase its own length with the movement of the thickening plate 7. The bottom surface of the sliding cavity 5 is provided with a fixed groove 11, and the bottom surface of the connecting plate 9 is integrally formed with the fixed block 12 which is detachably connected with the fixed groove 11. When the push rod 8 applies a pushing force to the connecting plate 9 to make it slide, the thickening plate 7 will slide downward under the action of its own gravity. At this time, the thickening plate 7 will apply a pulling force to the telescopic rod to increase its own length. When the thickening plate 7 slides to the bottom end of the sliding cavity 5, the fixed block 12 is clamped in the fixed groove 11. At this time, the thickening block can block the gap between the upper die 4 and the lower die 3, so as to improve the efficiency and yield of the equipment in use.
[0024] Working principle: in the initial state, when the upper die holder 1 and the lower die holder 2 abut, the bottom surface of the sliding rod 6 abuts with the top surface of the lower die 3, when the gap between the upper die 4 and the lower die 3 increases, the inclined surface of the sliding rod 6 abuts with the top surface of the lower die 3, the top surface of the lower die 3 exerts a pushing force on the sliding rod 6 to make it slide towards the rotating groove 10, the sliding of the sliding rod 6 exerts a pushing force on the pushing rod 8 to make it rotate, at this time, the other end of the pushing rod 8 rotates and pushes the connecting plate 9 to slide, so that the connecting plate 9 drives the thickening plate 7 to rotate towards the bottom surface, when the thickening plate 7 moves to the bottom surface of the sliding cavity 5, the fixed block 12 is clamped with the fixed groove 11, so as to realize the fixation between the thickening plate 7 and the upper die 4, so as to reduce the gap between the upper die 4 and the lower die 3 through the thickening plate 7.
[0025] The preferred embodiments of the utility model are described above, the protection scope of the utility model is not only limited to the above-mentioned embodiments, all technical solutions belonging to the utility model idea are the protection scope of the utility model. It should be pointed out that, for ordinary skilled in the art, some improvements and decorations without departing from the principle of the utility model, these improvements and decorations should also be regarded as the protection scope of the utility model.
