[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] Example 1

[0027] like Figure 1-Figure 5 As shown, the utility model provides a technical solution: a large-stroke servo punch, comprising: a punch body 1, a protective mechanism 2 is provided on one side of the punch body 1, the protective mechanism 2 comprises a baffle 1 21, a foam layer 1 22 is sleeved inside the baffle 1 21, the foam layer 1 22 is slidably connected to the baffle 1 21, a nylon mesh layer 23 is fixedly connected to one side of the foam layer 22, a foam layer 24 is fixedly connected to the side of the nylon mesh layer 23 away from the foam layer 1 22, an insert block 25 is fixedly connected to the outer surface of the baffle 1 21, a T-shaped block 26 is fixedly connected to the bottom of the baffle 1 21, the T-shaped block 26 is placed in a slide groove provided on the punch body 1, baffles 27 are provided on both sides of the baffle 1 21, the number of baffles 27 is two, a connecting block 28 is fixedly connected to the outer surface of the baffle 27, bolts 29 are passed through the connecting block 28 and the inside of the punch body 1, the bolts 29 are slidably connected to the connecting block 28, and the bolts 29 are threadedly connected to the punch body 1.

[0028] In this embodiment, by setting up a protective mechanism 2, it is possible to effectively prevent the fragments generated by the mold burst from harming the operator, and the baffle 1 21 is used to block the fragments on the front. Since the baffle 1 21 is internally sleeved with a foam layer 1 22, a nylon mesh layer 23 and a foam layer 2 24, larger fragments will be buffered and fall, while smaller fragments will be recovered by the foam layer 1 22, the nylon mesh layer 23 and the foam layer 2 24. The fragments will penetrate into the foam layer 1 22 or even the foam layer 2 24. In addition, the setting of the nylon mesh layer 23 can effectively block the fragments that penetrate the foam layer 1 22, and the two baffles 27 can effectively block the mold fragments with fewer sides, and the fragments splashing to the side will be blocked by the punch body 1.

[0029] Example 2

[0030] like Figure 1 , Figure 2 and Figure 6 As shown, a fixing mechanism 3 is provided inside one of the baffle plates 27, and the fixing mechanism 3 includes an angled block 31, which is placed inside the baffle plate 27, one end of the angled block 31 is fixedly connected to a moving block 32, and one end of the moving block 32 away from the angled block 31 is fixedly connected to an extrusion sheet 33, a spring 34 is provided on one side of the extrusion sheet 33, and two ends of the spring 34 are respectively fixedly connected to the outer surface of the extrusion sheet 33 and the inner wall of the baffle plate 27, and an adjusting rod 35 is fixedly connected to the outer surface of the extrusion sheet 33, and the adjusting rod 35 runs through the inside of the baffle plate 27, and the adjusting rod 35 is slidably connected to the baffle plate 27.

[0031] In this embodiment, by setting up a fixing mechanism 3, the baffle 21 can be conveniently fixed and released. At the same time, the fixing mechanism 3 can be used in conjunction with the plug block 25 and the T-shaped block 26. The T-shaped block 26 enables the baffle 21 to drive the plug block 25 to accurately engage and connect with the bevel block 31. In addition, an extrusion sheet 33 and a spring 34 are provided. The spring 34 is compressed by the extrusion sheet 33 so that the spring 34 generates an elastic force. When the extrusion of the bevel block 31 disappears, the bevel block 31 will automatically reset under the action of the elastic force of the spring 34.

[0032] Working principle:

[0033] like Figure 1-Figure 6As shown, when the utility model is in use, when the punch body 1 is used in conjunction with the mold to process parts, the baffle 1 21 can be slid and fixed by the fixing mechanism 3. When the baffle 1 21 slides, it will drive the T-shaped block 26 to slide in the slide groove provided on the punch body 1, and drive the insert block 25 to gradually approach the slot provided on one of the baffles 27. When the insert block 25 squeezes the bevel block 31, the bevel block 31 will gradually slide and retract into the inside of the baffle 27. At the same time, the bevel block 31 will use the moving block 32 and the squeezing sheet 33 to compress the spring 34, so that the spring 34 generates elastic force. When the insert block 25 completely enters the slot, the bevel block 31 will automatically rebound under the action of the elastic force of the spring 34, and tightly engage with the insert block 25 to maintain the stability of the baffle 1 21. When the mold is squeezed and burst, the fragments of the mold will be blocked by the baffle 27 and the baffle 1 21, and the fragments splashing from the front will be blocked by the foam layer 1 22, the nylon mesh layer 23 and other components. The larger fragments will fall on the punch body 1, and the smaller fragments will penetrate into the foam layer 1 22 and may penetrate the foam layer 1 22. Due to the obstruction of the nylon mesh layer 23, the fragments will not completely penetrate the foam layer 24, and then the foam layer 1 22, the nylon mesh layer 23 and the foam layer 2 24 will collect the smaller fragments to avoid scattering and affecting the punch body 1. If the mold is replaced, the adjusting rod 35 can be slid to release the clamping connection between the insert block 25 and the bevel block 31, and the bolt 29 can be turned to remove the baffle 27 until the mold is reinstalled.

[0034] The above description is only a preferred embodiment of the present invention and does not limit the present invention in other forms. Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes and apply it to other fields. However, any simple modification, equivalent change and modification made to the above embodiment based on the technical essence of the present invention without departing from the content of the technical solution of the present invention still falls within the protection scope of the technical solution of the present invention.
