Definitions

  • the present invention relates to the field of bushing technology, and more particularly to a punch bushing.
  • the bushing protection punch is generally used, but in actual use, because the bushing has long-term friction It will cause the wear of the die punch. Therefore, the designer chooses the material with lower hardness and better wear resistance as the bushing during the design, which can reduce the wear, but if the bushing is not worn out, it will be replaced in time. The wear of the die punch is poor in practicality and high in cost.
  • the present invention provides a new technical solution.
  • a punch bushing includes a bushing body, the bushing body including a bottom liner, a backing and a facing, the bottom liner, the backing and the facing being sequentially stacked from the inside to the outside to form an integral structure,
  • the bushing body is provided with a receiving groove adapted to the punch at a position corresponding to the base, wherein the facing is provided with a wear sensing area, and the bottom end of the wear sensing area passes through the elastic
  • the spring is connected to the top end of the bottom lining, and the inner lining is provided with a through groove for accommodating the spring, and both ends of the through groove communicate with the surface lining and the bottom lining.
  • the inner side wall of the facing is provided with a shoulder, and the inner liner and the inner liner are embedded in the facing by the shoulder.
  • a gap is reserved between the substrate and the liner, and the substrate is finely adjusted in position within the face by a spring.
  • the invention has the beneficial effects that the invention provides a bushing with a multi-layer structure, including a face lining, a lining and a bottom lining, and the wear sensing area on the lining is finely adjusted by the spring to the position of the lining even if the lining Excessive wear will not affect the underlay, thus protecting the die punch from wear, convenient and practical, and low cost.
  • Figure 1 is a schematic view of the structure of the present invention.
  • bushing body 1, bushing body, 2, underlay, 3, lining, 4, face lining, 5, accommodating groove, 6, wear sensing area, 7, spring, 8, through groove, 9, shoulder, 10 ,gap.
  • a punch bushing as shown in Figure 1, comprising a bushing body 1 comprising a backing 2, a backing 2 and a facing 3, the backing 2, the backing 3 and the facing 4 from the inside out
  • the laminated body is sequentially stacked to form an integrated structure, and the bushing body 1 is disposed at a position corresponding to the substrate 2
  • the accommodating groove 5 is matched with the punch, and the wear lining area 6 is disposed in the lining 4, and the bottom end of the wear sensing area 6 is connected to the top end of the lining 2 through the spring 7, and the lining 3 is provided with the lining 3
  • the through groove 8 of the spring 7 communicates with the face liner 4 and the backing 2 at both ends of the through groove 8.
  • the inner side wall of the face liner 4 is provided with a shoulder 9 in which the inner liner 3 and the inner liner 2 are embedded in the face liner 4, and the cover of the face liner 4 is such that the inner liner 3 and The backing 2 is not subject to wear.
  • a gap 10 is reserved between the backing 2 and the backing 3, and the underlay 2 is finely adjusted in the facing 4 by the spring 7, even if the facing 4 is excessively worn, the underlay 2 is not affected. To protect the die punch from wear.
  • the invention has the beneficial effects that the invention provides a bushing with a multi-layer structure, including a face liner, a backing and a backing, and the wear sensing area on the face liner is finely adjusted by the spring to adjust the position of the backing, thereby protecting the mold
  • the punch is not subject to wear, is convenient and practical, and has low cost.
