Problems solved by technology
During the movement of the mold, the air in the closed area is not easy to be quickly exhausted, so that the heat caused by friction between the mold structures is not easy to be taken away with the air, which will affect the movement of the punch, reduce the production speed, and even cause uneven parts. It affects the normal life of the fine punching die, so an exhaust device should be installed on the die structure

Embodiment Construction
[0015] The present invention will be further described below in conjunction with the accompanying drawings. The following examples are only used to illustrate the technical solution of the present invention more clearly, but not to limit the protection scope of the present invention.
[0016] like figure 1 As described above, a protective structure for a punch sheath provided by the present invention includes a punch 4, a punch fixing plate 2, a sheath 3, a cylindrical pad 5, and a backing plate 1, and the sheath 3 is arranged on the outside of the punch 4, The punch 4 and the sheath 3 are fixed on the punch fixing plate 2 together, and a cylindrical pad 5 is arranged behind the punch 4, and the diameter of the cylindrical pad 5 is larger than the diameter of the punch 4; the length of the punch 4 is smaller than that of the sheath 3 The length is 5 mm; the cylindrical pad 5 and the punch 4 are connected by riveting or frictional connection; the punch 4 and the cylindrical pa...

The invention discloses a punch sheath protective structure. The punch sheath protective structure comprises a punch, a punch fixing plate, a sheath, a cylindrical pad and a pad plate, the sheath is arranged outside the punch, the punch and the sheath are fixed to the punch fixing plate together, the length of the punch is shorter than the length of the sheath, and the cylindrical pad is arranged on the rear of the punch. The punch sheath protective structure is additionally provided with a cylindrical pad structure for the punch of a small hole punching die, can solve the technical problem that a slender punch is prone to be bent, collapsed and broken because the diameter of a punching hole is smaller than the thickness of a workpiece, and can protect the punch. According to the punch sheath protective structure, the strength of the punch is improved, the service life of the punching die is prolonged, and the processing and replacement of the punch are convenient.
Description
technical field [0001] The invention relates to the field of stamping dies, in particular to a protective structure for a punch sheath. Background technique [0002] When punching small holes, since the punched hole diameter is very small, the diameter of the punching punch is also small. If the ordinary punching method is used for punching, it is easy to cause the slender punch to bend, become unstable and break. Therefore, when punching a small hole, how to improve the strength of the punch and prevent it from breaking and bending is a key issue in punching a small hole. In the current prior art, the method for preventing small punches from breaking and bending mainly adopts a punch guiding structure, and the common methods include: a local guiding structure. In order to ensure the concentricity and relative position of the punch and die holes is correct, it is necessary to add an auxiliary guide device on the stripper plate, the punch fixing plate and the die parts, and ...
