The utility model discloses stamping die can eliminate the shaping when pressing the material face closed and corrugate, and then just also eliminate pit that appears after the plate shaping, defect such as sink, improve the drawing shaping quality of automobile body planking.
Description
Technical Field
The utility model relates to a stamping die that one set of mould has inside and outside pressure limit circle can adjust through interior pressure limit circle power and stroke, improves the automobile body planking and draws shaping quality.
Background
The mould to current interior, external pressure material circle, for example, the side wall, panorama skylight top cap, side wall and top cap stamping die are when debugging, interior, external pressure limit circle power is the same, the stroke is the same, the state of the unable true judgement plate of field force when debugging, can not guarantee to meet the demands to the percentage of closing of the grinding of stamping die profile, thereby lead to stamping die to check the time long, the number of times of making a complete change is many, influence stamping die's grinding efficiency and product pit, sink, quality defects such as corrugate, also cause the wasting of resources simultaneously.
SUMMERY OF THE UTILITY MODEL
The utility model aims at solving the technical problem, not enough to prior art's existence, the utility model provides an including the blank holder increase nitrogen cylinder, reduce the debugging degree of difficulty, improve the drawing shaping quality of outer plate spare. The utility model discloses the preparation is convenient, has good application prospect.
The utility model discloses a concrete technical scheme is: a stamping die with inner and outer pressing edge rings for controlling sheet material to flow comprises an upper die body 1, a lower die body 2, an inner pressing edge ring 9, an outer pressing edge ring 3, a male die 10, a female die, a secondary ejector rod 8, a nitrogen spring 5 and a limiting device 4; a female die is arranged on the upper die body 1, and a male die 10, an inner pressing edge ring 9 and an outer pressing edge ring 3 are arranged on the lower die body 2; the inner pressing edge ring 9 and the lower die body 2 are provided with a secondary ejector rod 8, and a nitrogen spring 5 and a limiting device 4 are arranged in the middle of the secondary ejector rod 8; the nitrogen spring 5 is arranged on the supporting plate 7, and the nitrogen spring 5 is used as a pressure source for the reciprocating motion of the inner pressure edge ring 9; the supporting plate 7 is provided with a safety screw 6; the limiting device 4 is used for limiting the lower die body 2 and the inner pressing edge ring 9.
Furthermore, the limiting device 4 is a limiting block.
When the device works, when a plate is drawn and formed, when an upper die body moves downwards, the pressure surface contacts the outer pressure edge ring and the inner pressure edge ring, the inner pressure edge ring plays a role in regulation through the nitrogen spring, the elasticity and the stroke of the nitrogen spring of the inner pressure edge ring are set to be matched with the inner pressure edge ring and the outer pressure edge ring, the depth offset between the inner pressure edge ring and the outer pressure edge ring is eliminated, the pressure is guaranteed to be simultaneously pressed with the outer pressure edge ring, so that the forming wrinkling is eliminated when the pressure surface is closed, the defects of pits, collapse and the like after the plate is formed are also eliminated, and the drawing and forming quality of an outer plate of an automobile body is improved.
Drawings
Fig. 1 is a schematic structural diagram of a stamping die with inner and outer press rims for controlling the flow of a sheet material.
In the figure: 1. the upper die body 2, the lower die body 3, the external pressing edge ring 4, the limiting device 5, the nitrogen spring 6, the safety screw 7, the supporting plate 8 and the secondary ejector rod 9 press the edge ring 10 and the male die.
Detailed Description
The principles of the present invention will be described in detail below with reference to the accompanying drawings for more clearly illustrating the technical solutions.
Fig. 1 is a schematic structural diagram of a stamping die with inner and outer press rims for controlling the flow of a sheet material. A stamping die with inner and outer pressing edge rings for controlling sheet material to flow comprises an upper die body 1, a lower die body 2, an inner pressing edge ring 9, an outer pressing edge ring 3, a male die 10, a female die, a secondary ejector rod 8, a nitrogen spring 5 and a limiting device 4; a female die is arranged on the upper die body 1, and a male die 10, an inner pressing edge ring 9 and an outer pressing edge ring 3 are arranged on the lower die body 2; the inner pressing edge ring 9 and the lower die body 2 are provided with a secondary ejector rod 8, and a nitrogen spring 5 and a limiting device 4 are arranged in the middle of the secondary ejector rod 8; the nitrogen spring 5 is arranged on the supporting plate 7, and the nitrogen spring 5 is used as a pressure source for the reciprocating motion of the inner pressure edge ring 9; the supporting plate 7 is provided with a safety screw 6; the limiting device 4 is used for limiting the lower die body 2 and the inner pressing edge ring 9.
The limiting device 4 is a limiting block.
When the stamping die is in a working state of stamping parts, the upper die body 1 is pressed downwards, the inner pressing edge ring 9 contacts the plate firstly, and the nitrogen spring 5 plays a role in pressing and adjusting. Through the adjustment of the nitrogen spring 5, no depth section difference exists between the outer pressing edge ring 3 and the inner pressing edge ring 9 when the pressing surface is closed and formed, and forming wrinkles are eliminated when the pressing surface is closed, so that the ideal state of parts is achieved.
