Description

Can solve mould structure of notching waste material rebound

Technical Field

The utility model relates to a die structure capable of solving the problem of rebound of notching waste in the aspect of stamping dies.

Background

In the aspect of the current stamping die, a common die structure capable of solving the problem of rebound of notching waste (the common die structure is described in domestic die professional literature < die manufacturing > journal 2015, 6, pages 22 to 24) is characterized in that: in the common die structure, the purpose that the punch waste is rebounded can be achieved by the common die structure because the punch does not bring the waste punched in the groove out of the groove in the whole process of punching the punch by the small ejection pin arranged on the ejection punch (the punch with the flat shape) in the upper die. Since only the common mold structural features are still somewhat unsatisfactory for mold technology, what is needed is a mold structure that can solve the problem of notching scrap rebound that is different from the common mold structural features.

Disclosure of Invention

The utility model aims to change the common die structure capable of solving the problem of the rebound of the notching waste in the aspect of the current stamping die and also meets the technical requirements of the die, and provides a die structure capable of solving the problem of the rebound of the notching waste, which is different from the common die structure in characteristics, and is characterized in that: in the provided die structure, the purpose that the punch can solve the rebound of the punching waste is achieved by arranging the V-shaped groove type on the middle part of the lower end face of the punch (the flat punch) in the upper die, so that the punch does not bring the waste punched in the groove out of the groove in the whole process of punching the punch.

The technical scheme of the utility model provides a die structure capable of solving the problem of rebound of notching waste, which comprises a fixed plate, a base plate, a male die and an upper die holder; the method is characterized in that: the position of the backing plate is on the lower bottom surface of the upper die holder, and the position of the fixing plate is on the lower bottom surface of the backing plate; the fixing plate is provided with male die positioning holes in the vertical direction; punch positioning hole: the hole is communicated with the upper end face and the lower end face of the fixed plate, and the depth of the hole is h1; regarding the construction of the punch itself prior to installation: the male die has a cross section with a length L3 and a width H, and a v-shaped groove is arranged in the middle of the lower end face of the male die, and the groove is internally provided with: the groove width is L1, the groove depth is h, the groove top width is L2, the groove bottom fillet radius is R1, and the fillet radii of the left and right side wall surfaces of the groove are respectively R; the male die is installed in place: the male die is arranged in the male die positioning hole on the fixing plate and is in place, and the upper top surface of the male die arranged in place is attached to the lower bottom surface of the backing plate.

The description of the die structure capable of solving the problem of rebound of notching waste is provided: firstly, the provided die has simple structure and convenient processing; secondly, on the die structure capable of solving the problem of rebound of notching waste, the provided die structure characteristics are different from those of the common die. Thirdly, a practical model that the notching waste of the die does not rebound is constructed; fourthly, on the aspect of solving the problem of rebound of the die notching waste, the die can replace the common die effect; fifthly, a mold structure capable of solving the problem of notching waste rebound is provided, and the problem of notching waste rebound of the same type of mold can be worth referencing.

Drawings

Referring to the drawings of the specification, FIG. 1 shows a mold structure capable of solving the problem of rebound of notching waste; FIG. 2 is a cross-sectional view A-A of FIG. 1; wherein: 1. a fixing plate; 2. a backing plate; 3. a male die; 4. an upper die holder;

Detailed Description

See the drawings in the specification, as shown in figure 1. The utility model provides a die structure capable of solving the problem of rebound of notching waste, which comprises a fixed plate 1, a base plate 2, a male die 3 and an upper die holder 4; the method is characterized in that: the position of the backing plate 2 is on the lower bottom surface of the upper die holder 4, and the position of the fixing plate 1 is on the lower bottom surface of the backing plate 2; the fixing plate 1 is provided with male die positioning holes in the vertical direction; punch positioning hole: the hole is communicated with the upper end face and the lower end face of the fixed plate 1, and the depth of the hole is h1; regarding the construction of the punch 3 itself prior to installation: the male die 3 has a cross section with a length L3 and a width H, and a groove shape with a V shape is arranged at the middle part of the lower end surface of the male die 3, and the groove shape is formed in the groove shape: the groove width is L1, the groove depth is h, the groove top width is L2, the groove bottom fillet radius is R1, and the fillet radii of the left and right side wall surfaces of the groove are respectively R; the male die 3 is installed in place: the male die 3 is arranged in a male die positioning hole on the fixed plate 1 and is in place, and the upper top surface of the male die 3 which is arranged in place is attached to the lower bottom surface of the backing plate 2.
