Abstract
Description
Technical Field
[0001] This utility model relates to the field of forging equipment technology, and more specifically, to a multifunctional forging upsetting auger and forging system. Background Technology
[0002] After the first heat treatment (normalizing and air cooling), the blanks of support rollers and other shaft forgings may be bent or not straight due to internal stress and other factors. A straightening process is required at this time to meet the subsequent processing dimensions.
[0003] In the relevant technology, the forging operator needs to use an overhead crane to lift away the fixtures on the press and the platform in advance, and place two lower V-anvils with a width of 600mm or 850mm. Then, the overhead crane is used to place the forging on the two V-anvils. The manipulator clamps one end of the forging and rotates the forging at a small angle in the axial direction to find the bending position of the forging. The platform is pulled to straighten the bending position with the press. The above operation is repeated to complete the forging straightening process.
[0004] However, the above process is complex, requires a lot of equipment, takes up time for overhead cranes and presses, and the forging operation is labor-intensive and inefficient. Utility Model Content
[0005] The problem this invention aims to solve is: how to reduce the labor intensity of forging operations and improve forging efficiency.
[0006] This utility model provides a multifunctional forging upsetting stencil, comprising: a stencil body, wherein the stencil body has a through hole structure along its axial direction, the through hole structure is configured to allow the riser end of a steel ingot billet to extend into it, and the ingot body of the steel ingot billet is used to abut against a first end face of the stencil body in the axial direction; the second end face of the stencil body in the axial direction has two symmetrically formed arc-shaped notches, the two arc-shaped notches being used to overlap and cooperate with the two roll necks of the forging blank.
[0007] The multifunctional forging upsetting die provided by this utility model has the following beneficial effects compared with the prior art:
[0008] The multifunctional forging upsetting stencil described in this utility model can satisfy both the upsetting process and the straight bending process of forgings. Specifically, when this multifunctional forging upsetting stencil is used in the upsetting process, the stencil body is first installed on a platform (equivalent to the ground) with the first end face of the stencil body facing upward. Then, the riser end of the steel ingot billet is inserted into the through hole structure, and the ingot body of the steel ingot billet abuts against the first end face. Subsequently, the press drives the upsetting cover plate to repeatedly press down on the steel ingot billet until the upsetting process is completed. When this multi-functional forging upsetting stencil is used in the straight bending process, the stencil body is first installed on the walkway with its second end face facing upwards. The forging blank is then placed horizontally on the second end face, with the two roller necks of the blank overlapping the two arc-shaped notches. One end of the blank is then clamped by a forging manipulator, which rotates the blank relative to the stencil body at a small angle. Once a bending position is detected, the walkway is pulled, and the bending position is straightened using a press and the upper anvil. This process is repeated to complete the straightening of the forging. Compared to related technologies, this multi-functional forging upsetting stencil can satisfy both the upsetting and straight bending processes of forgings. The overall process is simple to operate, reduces the need for forging fixtures, reduces equipment time, lowers the labor intensity of forging operators, and improves forging efficiency.

[0017] In addition, this utility model also provides a forging system, including the multifunctional forging upsetting auger as described above.

[0032] like Figures 1 to 5 As shown, the multifunctional forging upsetting stencil of this utility model includes: a stencil body 1, wherein the stencil body 1 has a through hole structure 13 along its axial direction, the through hole structure 13 is configured to allow the riser end 21 of the steel ingot billet 2 to extend into it, and the ingot body of the steel ingot billet 2 is used to abut against the first end face 11 of the stencil body 1 in the axial direction; the second end face 12 of the stencil body 1 in the axial direction has two symmetrical arc-shaped notches 14, the two arc-shaped notches 14 being used to overlap and cooperate with the two roll necks 72 of the forging blank 7 respectively.
[0033] In this embodiment, in conjunction with the appendix Figure 1 To be continued Figure 5As shown, the multifunctional forging upsetting die of this utility model can satisfy both the upsetting process and the straight bending process of forgings. Specifically, in conjunction with the attached... Figure 3 and attached Figure 4 As shown, when this multi-functional forging upsetting stencil is used in the upsetting process, the stencil body 1 is first installed on the walkway 4 (equivalent to the ground), with the first end face 11 of the stencil body 1 facing upwards (see attached diagram). Figure 3 Or attached Figure 4 The billet 2 is placed in the positive Z-axis direction. Then, the riser end 21 of the billet 2 is inserted into the through hole structure 13, and the body of the billet 2 abuts against the first end face 11. Subsequently, the press drives the upsetting cover plate 3 to repeatedly press down the billet 2 until the upsetting process is completed (the billet 2 is attached to the first end face 11). Figure 3 The state shown is compressed to the attached Figure 4 (as shown in the diagram). When this multi-functional forging upsetting stencil is used in the straight bending process, first, the stencil body 1 is installed on the walkway 4, with the second end face 12 of the stencil body 1 facing upwards (see attached diagram). Figure 3 Or attached Figure 4 Place the forging blank 7 horizontally (in the positive Z-axis direction). Figure 5 The blank 7 is placed on the second end face 12 (in the X-axis direction), and the two roller necks 72 of the forging blank 7 are respectively overlapped on the two arc-shaped notches 14. Then, one end of the forging blank 7 is clamped by the forging manipulator 5. The forging manipulator 5 can drive the forging blank 7 to rotate at a small angle relative to the die body 1. When a bending position of the forging is found, the table is pulled, and the bending position is straightened by the press driving the upper flat anvil 6. The above operation is repeated to complete the forging straightening process. Compared with related technologies, the multifunctional forging upsetting die of this utility model can meet both the upsetting process and the straightening and bending process of forging. The overall process is simple to operate, reduces the production of forging fixtures, reduces equipment time, reduces the labor intensity of forging operators, and improves the forging efficiency of forging.
[0034] Optionally, two first pin holes 15 are symmetrically formed along the radial direction of the drain plate body 1, and the two first pin holes 15 are located near the first end face 11.
[0035] In this embodiment, in conjunction with the appendix Figure 1 As shown, two first pin holes 15 are symmetrically opened along the radial direction of the sluice plate body 1. The first pin holes 15 are used to insert pins so as to facilitate hoisting by a crane. The two first pin holes 15 are located near the first end face 11. In this way, after the sluice plate body 1 is hoisted, the first end face 11 can be made to face upward under its own weight. After the sluice plate body 1 is hoisted onto the platform 4, the first end face 11 can be made to face upward so as to be used for the overlaying process.
[0036] Optionally, two second pin holes 16 are symmetrically formed along the radial direction of the drain plate body 1, and the two second pin holes 16 are located near the second end face 12.

The second pin holes 16 are used to insert pins to facilitate hoisting by overhead crane. The two second pin holes 16 are located near the second end face 12. In this way, after the sluice plate body 1 is hoisted, the second end face 12 will face upward under its own weight. After the sluice plate body 1 is hoisted onto the platform 4, the second end face 12 can be kept facing upward for use in the straight bending process.

[0039] In this embodiment, in conjunction with the appendix Figure 2 As shown, two arc-shaped notches 14 are symmetrically arranged on the second end face 12, with an opening of 100° to 110° (preferably 105°) and a depth of 300mm to 350mm (preferably 330mm). The arc-shaped notches 14 are adapted to the circumferential surface of the roll neck 72 of the forging blank 7, so that the roll neck 72 of the forging blank 7 can be rotated after overlapping the arc-shaped notches 14 for use in the straight bending process.
[0040] Optionally, the first end face 11 is a concave frustum.
[0041] In this embodiment, in conjunction with the appendix Figure 1 As shown, the first end face 11 is a concave inclined surface in the middle. This inclined surface slopes inward from the outer edge of the first end face 11 toward the through hole structure 13, thus presenting a conical surface with the tip cut off, also known as a frustum surface.

The diameter of the through hole structure 13 on the second end face 12 can be designed to be 1480mm to 1520mm, for example, 1500mm.
[0048] Optionally, the diameter of the through hole structure 13 on the second end face 12 is greater than the length of the roll body 71 of the forging blank 7.
[0049] In this embodiment, in conjunction with the appendix Figure 5 As shown, the diameter of the through hole structure 13 on the second end face 12 needs to be designed to be greater than the length of the roller body 71 of the forging blank 7, so that the roller body 71 can be fully accommodated in the through hole structure 13 during the straight bending process, and avoid interference between the roller body 71 and the squeegee body 1.

[0053] The terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature.
[0054] Although the present invention has been disclosed above, its protection scope is not limited thereto. Those skilled in the art can make various changes and modifications without departing from the spirit and scope of the present invention, and all such changes and modifications will fall within the protection scope of the present invention.
