The male die is arranged on the bottom of the main bolt.
The supporting beam is of an L-shaped structure.
The end part of the supporting beam is provided with a lap joint groove matched with the side bracket, and the side bracket is buckled in the lap joint groove and fixed by a secondary bolt.
The lap joint groove is provided with a threaded hole.
Compared with the prior art, the utility model has the beneficial effects that:
1. the edge pressing ring die extraction device for the sheet metal forming testing machine is simple and reasonable in overall structure, solves the problem of clamping of the edge pressing ring die in the use process, avoids damage caused by extracting the edge pressing ring die by using a hard tool, and simultaneously greatly improves the working efficiency.
2. The device adopts detachable construction, can make each part all get into the cavity and reassemble, makes things convenient for follow-up application of force to draw blank holder mould.
3. The main bolt is screwed to drive the support beam to move upwards, the clamping pins at the two sides clamp the blank holder die and drive the blank holder die to move upwards until the blank holder die loosens, the clamped blank holder die can be extracted, the force application process is uniform, and damage to the blank holder die is avoided.

Detailed Description
The present utility model will be described in detail below with reference to the drawings of the specification, but it should be noted that the practice of the present utility model is not limited to the following embodiments.
Referring to fig. 3-9, an extracting device for a blank holder die of a sheet metal forming testing machine comprises a main bolt 4, a secondary bolt 5, a supporting beam 6, a side support 8 and a clamping pin 7, wherein the supporting beam 6 and the side support 8 are fixedly connected through the secondary bolt 5 to form a -shaped structure, the clamping pin 7 is fixedly connected to the inner side of the bottom of the -shaped structure in a relative mode, the main bolt 4 is in threaded connection with the supporting beam 6, the main bolt 4 can be arranged in the middle of the -shaped structure, and the main bolt 4 can be abutted to a male die 2 through the bottom end of the supporting beam 6.
The device also comprises a rubber pad which is arranged between the bottom of the main bolt 4 and the male die 2, so that the male die 2 is prevented from being damaged. The support beam 6 has an L-shaped structure. The end of the supporting beam 6 is provided with a lap joint groove 9 matched with the side bracket 8, and the side bracket 8 is buckled in the lap joint groove 9 and fixed by the auxiliary bolt 5. The lap joint groove 9 is provided with a threaded hole 10 for connecting the auxiliary bolt 5.
Referring to fig. 3-9, when the blank holder die 3 is clamped in the cavity 1 and cannot be taken out, the auxiliary bolt 5 is removed, the side bracket 8 is removed, the clamping pin 7 of the supporting beam 6 is clamped between the blank holder die 3 and the bottom of the cavity 1, the supporting beam 6 is placed flat, the side bracket 8 is sent into the cavity 1, the clamping pin 7 on the side bracket 8 is clamped between the blank holder die 3 and the bottom of the cavity 1, the two clamping pins 7 are adjusted to be opposite positions, the side bracket 8 is lapped on the lapping groove 9, and the supporting beam 6 and the side bracket 8 are fixed by the auxiliary bolt 5. The sample device is installed on the blank holder die 3, as shown in fig. 5, a rubber pad with the diameter of 50mm and the thickness of 5mm is placed between the main bolt 4 and the male die 2, so that the main bolt 4 is prevented from being in hard contact with the male die 2, the main bolt 4 is screwed until the bottom is in contact with the rubber pad, and then the main bolt 4 is continuously rotated by a spanner until the blank holder die 3 loosens, and the clamped blank holder die 3 can be extracted. If the bottoms of the two sides of the blank holder die 3 are provided with extraction holes, the clamping pins 7 are directly inserted into the extraction holes.
