Description

Technical Field

[0001] This utility model relates to the field of forging technology, and in particular to a forging table for flanges. Background Technology

[0002] Flanges, or simply flanges, are one of the commonly used parts in pipeline connections. There are several ways to forge flanges. One method is to heat a cylindrical forging billet to a certain temperature and then hammer it multiple times with a forging hammer to form the basic shape of the flange. This process requires the cooperation of multiple people, such as someone to control the forging hammer, someone to place and remove the central through-hole mold on the billet, and at least one forklift to constantly correct the position of the forging billet. Usually, in order to facilitate the forging of the curved sidewalls and boss structures of the forging billet, two forklifts are needed to work together to rotate the forging billet. In addition, this forging process requires not only multiple workers, but also multiple workers who need to have a high degree of proficiency and tacit understanding to quickly complete the forging of the flange basic shape.

[0003] In view of this, there is an urgent need for a forging table for flanges to solve the above problems. Utility Model Content

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] Please see the appendix Figure 1-5 A forging table for flanges, comprising:

[0023] The base 1 comprises a base 1, a mold 2, a longitudinal moving component 3, and a transverse moving component 4. The top wall of the base 1 is provided with an installation cavity 10 and at least one mold connection hole 11. The longitudinal moving component 3 is installed in the installation cavity 10. The transverse moving component 4 is fixedly connected to the longitudinal moving component 3. The mold 2 includes a mold body 20 and a connecting post 21 fixedly connected to the bottom of the mold body 20. The connecting post 21 is placed in the mold connection hole 11.

[0024] In practical use, select the appropriate mold 2 and the matching transverse moving component 4 according to the size of the flange. Fix the mold 2 to the base 1 by inserting the connecting column 21 into the mold connecting hole 11. First, install the transverse moving component 4 on the longitudinal moving component 3. Then, adjust the actual application height of the longitudinal moving component 3 according to the height of the mold 2. It should be noted that a control console is provided to control the longitudinal moving component 3 and the transverse moving component 4 for easy operation. Considering that the oxide layer on the surface of the forged billet may peel off during the forging process of the flange, a certain distance is maintained between the control console and the base 1 to avoid oxide layer splattering and burning the staff. At the same time, the oxide layer located in the mold 2 can also serve as a partition to prevent the forged billet from sticking to the mold 2. If the forged annular billet is difficult to remove from the mold 2, the curved sidewall of the mold 2 can be connected by a snap-fit ​​method (as shown in the attached figure). Figure 5 ).

[0025] Specifically, the longitudinal moving component 3 includes a longitudinal hydraulic cylinder 30, a lifting platform 31, and multiple telescopic sleeves 32. The lifting platform 31 is slidably connected to the mounting cavity 10. The longitudinal hydraulic cylinder 30 is fixedly connected to the middle position of the mounting cavity 10, and its piston rod is fixedly connected to the lifting platform 31. One end of the telescopic sleeve 32 is fixedly connected to the bottom wall of the mounting cavity 10, and the other end is fixedly connected to the lifting platform 31.

[0026] Specifically, the lateral movement component 4 includes a lateral hydraulic cylinder 40, a U-shaped block 41, a connecting block 42, a locking component 43, and a position limiting block 44. The lateral hydraulic cylinder 40 is fixedly connected to the lifting platform 31, and the piston rod of the lateral hydraulic cylinder 40 is fixedly connected to the side wall of the U-shaped block 41 away from the notch. The position limiting block 44 is located between the mold 2 and the lateral hydraulic cylinder 40, and its lower end passes through the notch of the U-shaped block 41 and is fixedly connected to the lifting platform 31. The position limiting block 44 is provided with a position limiting hole 440. The end of the connecting block 42 away from the mold 2 is movably connected to the notch of the U-shaped block 41, and its end near the mold 2 is movably connected to the locking component 43. The end of the connecting block 42 away from the mold 2 passes through the position limiting hole 440.

[0027] In practical use, after placing the mold body 20, select the appropriate countersink and locking assembly 43 according to the size of the flange, and install the countersink and locking assembly 43 on the end of the connecting block 42 near the mold body 20. Then, control the extension and retraction of the piston rod of the longitudinal hydraulic cylinder 30 through the control console so that the height of the lifting platform 31 matches the height of the mold body 20. During forging, after placing the high-temperature forging billet on the mold body 20, the forging billet is deformed by the forging hammer and finally forms a disc-shaped billet similar in shape to the mold body 20. At this time, the extension and retraction of the piston rod of the transverse hydraulic cylinder 40 can be controlled to drive the U-shaped block 41 to move towards one side of the mold body 20. Then, the countersink is moved to the center of the mold body 20 through the connecting block 42 and locking assembly 43. Finally, the countersink is completed by striking the countersink with the forging hammer.

[0028] Specifically, the top wall of the connecting block 42 near the transverse hydraulic cylinder 40 is curved. Considering that the height of the disc-shaped blank inside the mold body 20 should be lower than that of the mold body 20, and the lower end of the countersink needs to contact the disc-shaped blank, the top wall of the connecting block 42 and the locking component 43 is constructed with a curved surface. When the connecting block 42 moves toward the mold body 20, due to the curved surface, the locking component 43 will move in the direction of the countersink base 1 and contact the disc-shaped blank.

[0029] Specifically, the U-shaped block 41 is provided with a locking pin 410 at the end away from the transverse hydraulic cylinder 40, which is movably connected to it. The locking pin 410 passes through the middle position of the U-shaped block 41 and the connecting block 42, and the locking pin 410 and the connecting block 42 are in clearance fit. Considering that during the forging hammer strike, there may be a situation where the countersinking drill drives the connecting block 42 to vibrate, the curved arc design of the end of the connecting block 42 away from the mold body 20 allows the connecting block 42 to have rotational margin. The connecting block 42 is movably connected to the notch position of the U-shaped block 41 through the locking pin 410, so that the connecting block 42 can rotate slightly about the locking pin 410 as the axis to alleviate the vibration it receives and prevent the vibration from being transmitted to the U-shaped block 41 and the transverse hydraulic cylinder 40, causing damage to the parts.

[0030] Specifically, the locking assembly 43 includes two sets of arc-shaped locking blocks 430, two sets of straight shanks 431, and a locking screw 431. The two sets of straight shanks 431 are detachably connected to the end of the connecting block 42 near the mold 2 via the locking screw 431, and the two sets of arc-shaped locking blocks 430 are fixedly connected to the end of the straight shanks 431 away from the connecting block 42. Considering that there are many types of countersinks, detachable arc-shaped locking blocks 430 are used, and different countersinks are selected according to different types of countersinks.

[0031] Specifically, the mold body 20 is provided with two sets of lifting lugs 200 that are fixedly connected to it.

[0032] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
