Description

Technical Field

[0001] The utility model belongs to the technical field of alloy forging, and in particular relates to an auxiliary positioning device for super-large shallow cavity forgings. Background Art

[0002] In the die forging process, the forging is first given certain structural features by blank making, and the features are used to position it in the die to complete the forging process. However, due to the structural characteristics of shallow cavity forgings, it is difficult to quickly and accurately position the blank in the die, and it is necessary to rely on the experience of on-site forgers to move the forgings for positioning. If the transfer time exceeds the process requirements, it will inevitably affect the microstructure and performance of the forgings. If the positioning deviation of the forgings is large, it will inevitably affect the final forging molding, resulting in insufficient product processing, and the microstructure and performance do not meet the requirements or there is no processing allowance, which will lead to the scrapping of the forging products. Utility Model Content

[0003] The utility model aims to provide an auxiliary positioning device for super-large shallow cavity forgings, which overcomes the defect of relying on on-site forgers to move forgings for positioning based on experience, and improves the organizational properties of forgings.

[0004] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0005] An auxiliary positioning device for an oversized shallow cavity forging, comprising a positioning member and a connecting member, wherein the connecting member is mounted on the side wall of a mold, a mounting hole is formed on the upper portion of the connecting member, a bolt is provided in the mounting hole, and the connecting member is movably connected to the positioning member through the bolt, and both sides of the positioning member are connected with connecting members; the bottom surface of the positioning member and the side surface away from the connecting member are planes, and when positioning, the bottom surface of the positioning member fits with the top surface of the mold, and the side surface away from the connecting member contacts with the positioned forging;

[0006] By setting two auxiliary positioning devices on the two vertical sides of the die, the forging can be quickly positioned;

[0007] The method of using the auxiliary positioning device is as follows: first restore the positioning auxiliary device to its initial position, where the positioning piece is located on the side of the mold; then flip it 270° to make the bottom surface of the positioning piece fit with the top surface of the mold, and the side of the positioning piece away from the connecting piece coincides with the positioning position in the mold cavity; then transfer the forging from the heating furnace to the mold cavity, and place the forging so that it contacts the positioning piece in both directions; finally, flip the positioning piece 270° back to the side of the mold, press the forging according to the process curve, and take out the forging after the die forging is completed.

[0008] Furthermore, the positioning member is in an overall rectangular frame structure.

[0009] Furthermore, the connecting piece and the positioning piece are both made of angle steel.

[0010] The beneficial effects of the utility model are as follows: the auxiliary positioning device is made of angle steel, and the auxiliary positioning device is divided into a connecting piece and a positioning piece. The lower part of the connecting piece is fixed to the side of the mold, and the upper part is connected to the positioning piece by screws and can be rotated 270 degrees. During the forging production process, the forging is placed against the positioning piece, so that the forging can be quickly and accurately positioned in the cavity, which can greatly reduce the transportation time, increase the initial forging temperature, and improve the accuracy of the forging material swing, avoiding product quality problems caused by too low final forging temperature and inaccurate swing position. After the forging production is completed, the positioning piece is rotated 270 degrees to the side of the mold or it is removed as a whole for storage, which does not affect the normal stacking of the mold.

[0014] like Figure 1 and Figure 2 As shown, this embodiment provides an auxiliary positioning device for ultra-large shallow cavity forgings. The auxiliary positioning device is installed on the mold 1 to achieve the function of quickly positioning the forging 2, shorten the transportation time, and improve the organizational properties of the forging 2.

[0015] The auxiliary positioning device includes a positioning member 4 and a connecting member 3. The connecting member 3 is installed on the side wall of the mold 1 and can be installed by detachable parts such as bolts or by fixing methods such as welding. A mounting hole is opened on the upper part of the connecting member 3, and a bolt is arranged in the mounting hole. The connecting member 3 is movably connected to the positioning member 4 through the bolt. In order to ensure the stability of the positioning member 4, the connecting members 3 are connected to both sides of the positioning member 4, and the positioning member 4 is stabilized by the connecting members 3 on both sides.

[0016] In order to ensure the positioning function of the positioning piece 4, its bottom surface and the side surface away from the connecting piece 3 are flat. During positioning, the bottom surface of the positioning piece 4 fits with the top surface of the mold 1, and the side surface away from the connecting piece 3 contacts the positioned forging 2, so that one side of the forging 2 can be quickly positioned. By setting up two auxiliary positioning devices, the positioning of the forging 2 in all directions can be achieved.

[0017] The positioning member 4 described in this embodiment has an overall rectangular frame structure, which can realize positioning recovery and reduce the weight of the positioning member 4. When processed in the mold 1, the positioning member 4 is flipped upward and rotated 270° around the connection point of the positioning member 4 connector 3. During the forging process, it is not affected by the mold 1 or the auxiliary positioning member 4.

[0018] The connecting member 3 and the positioning member 4 described in this embodiment are both made of angle steel, which has a reasonable design and can be easily manufactured.

[0019] The method of using the auxiliary positioning device is as follows: first, fix the connecting piece 3 on the two sides of the mold 1, and connect the positioning piece 4 to the connecting piece 3; then flip the positioning piece 4 270°, so that the bottom surface of the positioning piece 4 fits with the top surface of the mold 1, and the side of the positioning piece 4 away from the connecting piece 3 coincides with the positioning position in the cavity of the mold 1; then transfer the forging 2 from the heating furnace to the cavity of the mold 1, and the forger swings the forging 2 to contact the positioning piece 4 in both directions; finally, flip the positioning piece 4 270° back to the side of the mold 1, press the forging 2 according to the process curve, and take out the forging 2 after the die forging is completed.

[0020] The above is only a preferred implementation of the present invention, but the protection scope of the present invention is not limited thereto. Any modification and replacement based on the technical solution and utility model concept provided by the present invention should be included in the protection scope of the present invention.
