The embodiment provides an utensil is assisted to external forging frock, refer to fig. 1 to 11, including roof beam body 1, tup 2 and forging platform 3, the one end of definition roof beam body 1 is for forging the side, and the forging side of roof beam body 1 is located to tup 2, and the other end of definition roof beam body 1 is not forged the side, and the non-forging side of roof beam body 1 is connected with the installation face of forging and pressing equipment, and forging platform 3 locates tup 2 under, and the forging side of roof beam body 1 is located the region that the stand 12 of forging and pressing equipment encloses.

In the implementation, the upper end face of the beam body 1 is connected with a movable cross beam 4 of forging equipment, the movable cross beam 4 is positioned between a forging side and a non-forging side, the beam body 1 and the movable cross beam 4 form a shoulder pole beam, and a blank 12 is placed on a forging platform 3; in the activity process of movable cross beam 4, the forging side rotates around the non-forging side, and the movable cross beam 4 of forging equipment can transmit the load applied to the beam body 1 from the inside of the forging equipment to the forging side outside the forging equipment, the hammer 2 forges the blank 12 on the forging platform 3, and the hammer 2 and the forging platform 3 act together to deform the blank 12, so that the external forging of the forging equipment and the forging of the ultra-large forging are realized.

Compared with the prior art, the external forging tool assistive device provided by the embodiment is characterized in that the upper end face of the beam body 1 is connected with the movable cross beam 4 of forging equipment through the arrangement of the beam body 1, the forging side rotates around the non-forging side in the moving process of the movable cross beam 4 to form the shoulder pole beam, compared with the movable cross beam 4, the moving distance of the forging side is greater than that of the movable cross beam 4, and the forging forming process is moved outside the press body, so that the external forging tool assistive device is not limited by the structural size (such as span and column spacing) of the forging equipment, and an ultra-large forging part exceeding the span is integrally formed in a free forging mode.

From the viewpoint of moment balance, the position of the joint of the movable cross beam 4 and the beam body 1 is adjustable, and for example, the position can be located at the midpoint between the forged side of the beam body 1 and the non-forged side of the beam body 1.

In the case of an ultra-large cake (for example, a cake having a diameter of 7.5m or more), the hammer head 2 is a widening hammer head, that is, a hammer head 2 having a narrow anvil width and a long anvil length, and the size of the widening hammer head is not limited, for example, the anvil width is 400 to 450mm, and the anvil length is 3.5 to 4.5 m. When the hammer head 2 is designed, the forging load is considered, the auxiliary tool for external forging is adopted to conduct the forming force, the moment balance is considered, the load applied to the hammer head 2 is only half of the actual load of forging equipment, and therefore the anvil width of the expanded hammer head is half of the anvil width of the traditional expanded hammer head.

Considering that the beam body 1 is a main force transmission component in the tool auxiliary tool and is used for moving the vertical load of the movable cross beam 4 of the forging equipment to the outer side of the forging equipment (namely, on the hammer head 2), the beam body 1 is exemplarily a plate welding beam body, a forge welding beam body or a whole forging beam body. However, the beam 1 may be a welded beam as long as the mechanical strength is acceptable in view of the returning force of the return cylinder of the forging press.

To roof beam body 1's structure, particularly, it includes that the polylith is along the bearing board that vertical direction arranged and is located the grub bar between two adjacent bearing boards, connect polylith bearing board for whole rectangle box structure through the grub bar, constitute stable in structure's roof beam body 1, adopt bearing board and grub bar to constitute hollow overall structure, on guaranteeing that roof beam body 1 has enough structural strength's basis, can effectively reduce roof beam body 1's whole weight, make it can not exceed the return force that forging and pressing equipment return stroke jar provided, it is convenient and the cost is lower to make, stronger reliability has during the labour service, thereby can improve roof beam body 1's life.

In order to further improve the structural strength of the beam body 1, the beam body further comprises a transverse rib arranged between two adjacent vertical ribs, so that the two adjacent vertical ribs can be connected through the arrangement of the transverse rib, and the structural strength of the beam body 1 is further improved.

In order to further enhance the strength of the lower end surface of the bearing plate, the beam body 1 further comprises a transverse tie bar, for example, a trapezoidal transverse tie bar, arranged on the lower end surface of the bearing plate. Therefore, the strength of the lower end face of the bearing plate can be effectively enhanced through the arrangement of the transverse tie bars, and the force transmission of the bearing plate in the using process is ensured.

It is worth noting that, in the moving process of the movable cross beam 4, the moving of the movable cross beam 4 is up-and-down movement, the moving of the beam body 1 is up-and-down movement and rotation composite movement, in order to make up the movement difference between the movable cross beam 4 and the beam body 1, the tool assistive device further comprises a beam body connecting piece, the movable cross beam 4 is connected with the beam body 1 through the beam body connecting piece, specifically, the beam body connecting piece comprises an upper beam body connecting plate 5 and a lower beam body connecting plate 6 hung below the upper beam body connecting plate 5, the upper beam body connecting plate 5 is in cylindrical surface contact with the lower beam body connecting plate 6, the upper beam body connecting plate 5 is fixedly connected with the movable cross beam 4, and the lower beam body connecting plate 6 is fixedly connected with the beam body 1. Like this, through set up roof beam body connecting piece between movable cross beam 4 and roof beam body 1, the face of cylinder between roof beam body connecting plate 5 and the underbeam body connecting plate 6 slides in the roof beam body connecting piece, can compensate the motion difference between movable cross beam 4 and the roof beam body 1, make roof beam body 1 and movable cross beam 4 follow-up, realize the swing and the rotation of certain range, turn into cylinder flexonics with the rigid connection between roof beam body 1 and movable cross beam 4, avoid movable cross beam 4 and roof beam body 1 to produce too big strong moment of torsion in the junction.

When the beam body 1 is designed, not only the size of a forging applied by external forging, such as the diameter of a tube plate, the length of a cylinder forging and other parameters, but also the load transmitted by the beam body 1 need to be considered, so that the position of the joint of the movable cross beam 4 and the bearing plate adopts an adjustable structure, specifically, the upper end surface of the bearing plate is provided with a plurality of connecting holes, and the lower beam body connecting plate 6 is fixedly connected with the bearing plate through the connecting holes. Therefore, the lower beam body connecting plate 6 is connected with different connecting holes, the position of the connecting part of the movable beam 4 and the bearing plate can be changed, and further the distance that the forging end of the bearing plate extends out of the forging equipment is changed, and it should be noted that the farther the distance that the forging end of the bearing plate extends out of the forging equipment is, the smaller the load of the forging equipment transmitted by the beam body 1 is.

In order to ensure the smoothness of the sliding cylindrical surface between the upper beam connecting plate 5 and the lower beam connecting plate 6, the convex radius of the upper beam connecting plate 5 is smaller than the concave radius of the lower beam connecting plate 6, and exemplarily, the ratio of the convex radius of the upper beam connecting plate 5 to the concave radius of the lower beam connecting plate 6 is 0.9 to 0.98: 1. this is because, the ratio of the convex radius of the upper beam connecting plate 5 to the concave radius of the lower beam connecting plate 6 is limited within the above range, and not only can the smoothness of sliding between the upper beam connecting plate 5 and the lower beam connecting plate 6 be ensured, but also the contact area between the upper beam connecting plate 5 and the lower beam connecting plate 6 can be ensured, thereby effectively resisting impact load.

It is worth noting that the convex radius design of the upper beam connecting plate 5 depends on the maximum offset center distance of the forging equipment and the maximum inclination angle of the bearing plate, and the larger the maximum inclination angle is, the larger the required convex radius of the upper beam connecting plate 5 is, specifically, the convex radius of the upper beam connecting plate 5 is calculated by the following formula:

δ＝R×sinα

delta is the maximum unbalance loading center distance of forging equipment, R is the convex radius of the upper beam body connecting plate 5, and alpha is the maximum inclination angle of the bearing plate.

In order to ensure stable connection between the upper beam connecting plate 5 and the lower beam connecting plate 6, the number of the beam connecting sleeves is plural, for example, 4, and stable connection between the upper beam connecting plate 5 and the lower beam connecting plate 6 can be achieved by the plural beam connecting sleeves.

The upper end face of the upper beam body connecting plate 5 is provided with a dovetail protrusion, the lower end face of the upper anvil block 7 is provided with a dovetail groove, and the dovetail protrusion is inserted into the dovetail groove, so that the upper anvil block 7 is rigidly and fixedly connected with the upper beam body connecting plate 5; or, the lower end surface of the upper anvil block 7 is provided with a dovetail projection, the upper end surface of the upper beam body connecting plate 5 is provided with a dovetail groove, and the dovetail projection is inserted into the dovetail groove, so that the upper anvil block 7 and the upper beam body connecting plate 5 are rigidly and fixedly connected.

It is also worth noting that the motion of the beam body 1 is rotation, in order to ensure that the working surface of the hammer 2 can better contact with the blank 12, the tool auxiliary device further comprises a hammer head connecting piece, the hammer 2 is connected with the forging side of the beam body 1 through the hammer head connecting piece, particularly, the hammer head connecting piece comprises an upper hammer head connecting plate 9 and a lower hammer head connecting plate 10 hung below the upper hammer head connecting plate 9, the upper hammer head connecting plate 9 is in spherical contact with the lower hammer head connecting plate 10, the upper hammer head connecting plate 9 is fixedly connected with the forging side of the beam body 1, and the lower hammer head connecting plate 10 is fixedly connected with the hammer head 2. This is because, the forging highly reduces gradually at the deformation in-process, increase along with 2's of tup rolling reduction, roof beam body 1 can take place the tilting of certain degree, through set up the tup connecting piece between 2 and roof beam body 1's the forging side at tup, the sphere between middle-upper tup connecting plate 9 of tup connecting piece and lower tup connecting plate 10 slides, can turn into cylinder flexonics with the rigid connection between 2 and the forging side of roof beam body 1 of tup, make the tup 2 can take place the swing of certain degree, guarantee the forging face of 2's of tup axis perpendicular to blank 12, be surface contact between 2's the working face of tup and the forging face of blank 12, improve the quality of forging gained forging.

In order to guarantee the gliding smoothness nature of sphere between last tup connecting plate 9 and the lower tup connecting plate 10, the convex surface radius of above-mentioned last tup connecting plate 9 is less than the concave surface spherical radius of lower tup connecting plate 10, and exemplarily, the convex surface radius of going up tup connecting plate 9 is 0.9 ~ 0.98 with the concave surface spherical radius's of lower tup connecting plate 10 ratio: 1. this is because, inject the convex surface radius of last tup connecting plate 9 and the concave surface spherical radius of lower tup connecting plate 10 in above-mentioned within range, not only can guarantee to go up the gliding smoothness nature of sphere between tup connecting plate 9 and the lower tup connecting plate 10, can also guarantee to go up the area of contact of tup connecting plate 9 and lower tup connecting plate 10 to effective impact load.
