Technical Field

[0001] The utility model relates to the technical field of stainless steel flange forgings, in particular to a stainless steel flange forging die. Background Art

[0002] Stainless steel flange forging die is a process die used to manufacture stainless steel flange forgings, usually composed of a tool die, an upper die and a lower die. In the production process of stainless steel flange forgings, it is necessary to use a forging die to apply pressure and shape to the stainless steel material, so that it can be plastically deformed under high temperature, and finally obtain flange forgings that meet the requirements.

[0003] After searching, the Chinese patent "A Stainless Steel Flange Forging Die" authorization announcement number "CN215467829U" realizes the addition or reduction of limit rings on the die kit inside the die base through the die base and the die kit, which facilitates the adjustment of the forging size of the flange, and then facilitates the forging of flanges of different sizes.

[0004] The above-mentioned three limiting rings of different diameters are located in the mold base at the same time and have different heights. It is inconvenient to remove the other two limiting rings of different diameters, resulting in a height difference in the mold base, which in turn causes the stainless steel flange forging to be unstable in position in the mold, thereby easily affecting the forging accuracy of the stainless steel flange.

[0005] Therefore, a stainless steel flange forging die is proposed to solve the above problems. Utility Model Content

DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] When implementing: Figure 1-4As shown, a forging die for a stainless steel flange forging comprises: a die base 1, a limiting ring 2 is arranged on the inner side of the die base 1; a disassembly and assembly mechanism 3, which is arranged on the inner wall of the die base 1; wherein the disassembly and assembly mechanism 3 comprises two limiting blocks 31 fixedly connected to the surface of the limiting ring 2, the surface of the limiting blocks 31 is clamped on the inner side of the die base 1, the front and rear ends of the inner wall of the die base 1 are slidably connected with movable frames 32, the opposite ends of the two movable frames 32 are fixedly connected with fixed blocks 33 distributed in equal rows, and the front and rear ends of the limiting blocks 31 are A plurality of clamping blocks 34 are fixedly connected, a mounting block 36 is fixedly connected to one side of the mold base 1, a positioning frame 37 is slidably connected to the inner wall of the mounting block 36, the upper end of the surface of the positioning frame 37 is clamped to the inner wall of the movable frame 32, a fixing rod 313 is fixedly connected to one side of the limit block 31, a placing block 311 is fixedly connected to the lower end of the surface of the positioning frame 37, the lower end of the surface of the limit block 31 is in a "V" shape, the clamping block 34 and the fixed block 33 are both in a right triangle as a whole, and the inclined surface of the clamping block 34 abuts against the inclined surface of the fixed block 33.

[0025] A forging table is provided at the bottom of the die base 1, a hydraulic cylinder is fixedly connected to the top of the forging table, and the bottom end of the hydraulic cylinder passes through the forging table and is fixedly connected to an upper die.

[0026] When the limiting ring 2 in the die base 1 needs to be replaced, the placement block 311 is pulled downward to move the positioning frame 37 away from the movable frame 32, and the two movable frames 32 are pushed away from each other, so that the multiple fixed blocks 33 are away from the clamping block 34, and the fixing rod 313 is lifted to quickly move the limiting block 31 away from the die base 1, so that the limiting ring 2 is separated from the die base 1. At this time, the limiting ring 2 of the corresponding diameter is moved to the top of the die base 1 through the fixing rod 313, and the limiting ring 2 is quickly and accurately installed in the die base 1 through the limiting block 31 with a "V" shape at the lower end of the surface. Because the clamping block 34 and the fixing block 33 are both right-angled triangles as a whole, the inclined surface of the clamping block 34 is against the inclined surface of the fixing block 33, and the limiting block 31 The downward movement in the die base 1 drives the inclined surface of the clamping block 34 to move on the inclined surface of the fixed block 33. After the limit block 31 moves down to an appropriate position, the straight surface of the top of the clamping block 34 is against the straight surface of the bottom of the fixed block 33, so that the limit ring 2 is installed in the die base 1, avoiding the height difference in the die base 1. At this time, the stainless steel flange forging is placed in the limit ring 2, and the hydraulic cylinder is manually opened. The bottom end of the hydraulic cylinder moves downward, driving the lower die to move downward and hit the stainless steel flange forging to perform the forging operation. Because there is only one limit ring 2 in the die base 1, there will be no height difference in the die base 1, so that the forging accuracy of the stainless steel flange forging is enhanced. After the stainless steel flange forging is no longer needed to be forged, the hydraulic cylinder is manually closed.

The spring 35 and the spring 39 are both titanium alloy components.

[0028] The elastic force of the spring 35 pushes the movable frame 32 and the fixed block 33 to move toward the blocking block 34, so that the fixed block 33 contacts the blocking block 34. At this time, the elastic force of the spring 39 pushes the positioning frame 37 to move up and engage with the movable frame 32. The screw 38 is rotated so that the screw 38 is threadedly connected in the mounting block 36 and the positioning frame 37. The movement of the screw 38 drives the movable disk 310 to move, so that the guide rod 312 is engaged in the movable disk 310, and the screw 38 is limited. The positioning frame 37 is stably installed in the mounting block 36, and the limiting ring 2 is stably installed in the mold base 1.

[0029] When the utility model is in use, the screw rod 38 is rotated to make the screw rod 38 away from the positioning frame 37, the placement block 311 is pulled down, the positioning frame 37 is away from the movable frame 32, the two movable frames 32 are pushed away from each other, the multiple fixed blocks 33 are away from the clamping block 34, the fixing rod 313 is lifted, the limit block 31 is quickly away from the mold base 1, and the limit ring 2 is separated from the mold base 1. At this time, the limit ring 2 of the corresponding diameter is moved to the top of the mold base 1 through the fixing rod 313, and the limit ring 2 is quickly and accurately installed in the mold base 1 through the limit block 31 with a "V" shape at the lower end of the surface. Because the clamping block 34 and the fixing block 33 are integrally formed The right triangle, the inclined surface of the clamping block 34 is in contact with the inclined surface of the fixed block 33, the limit block 31 moves downward in the mold base 1, driving the inclined surface of the clamping block 34 to move on the inclined surface of the fixed block 33, after the limit block 31 moves down to a suitable position, the straight surface of the top of the clamping block 34 is in contact with the straight surface of the bottom of the fixed block 33, the screw 38 is rotated, and the screw 38 is threadedly connected in the mounting block 36 and the positioning frame 37, the movement of the screw 38 drives the movable disk 310 to move, so that the guide rod 312 is clamped in the movable disk 310, so that the positioning frame 37 is stably installed in the mounting block 36, and the limit ring 2 is stably installed in the mold base 1, avoiding the height difference in the mold base 1.
