Abstract
The utility model provides a stamping device with an inwards concave stamping head, and relates to a stamping device. The stamping device with the inwards concave stamping head resolves the problems that the end surface of a work end of a stamping head of an existing stamping device is usually a straight surface, so that a stamped structure is not good in interlocking performance and low in connection strength. An annular groove is arranged at the edge of the end surface of a work end of a stamping head of the stamping device, a round groove is arranged in the middle of the end surface of the work end of the stamping head, and a 45-degree transition chamfer is arranged in the position of a cutting edge of a section cavity of a concave mold. The stamping head of the stamping device is designed in to a structure with the inwards concave end surface, the stamping head and the concave mold are matched for use, the contact area between plates with the stamping structure part is increased, the interlocking performance and the connection strength of the stamping structure are improved, a transition inclined edge is arranged in the position of the cutting edge of the concave mold, so that the connection thickness of the position is increased, the position is not easy to break, stress concentration is reduced, and the connection strength of stamped plates is further improved.
Description
Technical field
The utility model relates to a kind of decompressor.
Background technology
Decompressor is the equipment that two or more homogeneities or different Jie's sheet material are linked together, the drift working end end face of existing decompressor generally all is to face (as shown in Figure 1) directly, cause that structural interlock after the punching press is bad, bonding strength is low, affects the connection reliability of pressing sheet material.
The utility model content
The utility model is generally all faced directly for the drift working end end face that solves existing decompressor, causes the problem that structural interlock is bad, bonding strength is low after the punching press, and then a kind of decompressor of nose of punch indent is provided.
The utility model is to solve the problems of the technologies described above the technical scheme of taking to be:
The decompressor of a kind of nose of punch indent described in the utility model comprises die, drift and blank holder, and blank holder centering places die top, drift can pass blank holder and matches with die cavity on the die; The arris place of the working end end face of described drift is provided with cannelure, and the middle part of the working end end face of described drift also is provided with circular groove, and the cutting edge position of the die cavity of described die is provided with 45 and spends and cross chamfering.
The beneficial effects of the utility model are:
Drift in the decompressor described in the utility model is designed to the structure of end face sunken inside, the drift use that matches with die, increased with the contact area between the sheet material of punching structure part, interlocking capability and the bonding strength of punching structure have been improved, and the cutting edge position of die also is provided with transition hypotenuse (chamfering), the connection thickness at this position increased, not easy fracture, reduce stress and concentrate, further improved the bonding strength of pressing sheet material.The punching press that the utility model is applicable to two or more homogeneities or different Jie's sheet material connects.
Description of drawings
Fig. 1 is diel schematic diagram of the prior art; Fig. 2 is the structural representation (before stamping) of decompressor described in the utility model, and Fig. 3 is the structural representation (after stamping) of decompressor described in the utility model; Among the figure: 1-die, 2-sheet material one, 3-sheet material two, 4-drift, 5-blank holder.
The specific embodiment
The specific embodiment one: shown in Fig. 2 and 3, the decompressor of the described a kind of nose of punch indent of present embodiment comprises die 1, drift 4 and blank holder 5, blank holder 5 centerings place die 1 top, and drift 4 can pass blank holder 5 and match with die cavity 1-1 on the die 1; The arris place of the working end end face of described drift 4 is provided with cannelure 4-1, and the middle part of the working end end face of described drift 4 also is provided with circular groove 4-2, and the cutting edge position of the die cavity 1-1 of described die 1 is provided with 45 and spends and cross chamfering 1-1-1.
The specific embodiment two: shown in Fig. 2 and 3, the height of the described transition chamfering of present embodiment 1-1-1 be die 1 die cavity 1-1 the degree of depth 1/3 to 1/2 between.Arrange like this, further improved the bonding strength of pressing sheet material, other composition and annexation are identical with the specific embodiment one.
The specific embodiment three: shown in Fig. 2 and 3, the internal diameter at the described circular groove 4-2 of present embodiment notch place be drift 4 diameter 1/3.Other composition and annexation are identical with the specific embodiment two.
Above-mentioned embodiment should not be considered as restriction of the present utility model, but any improvement of doing based on design of the present utility model, all should be within protection domain of the present utility model.
