Description

Technical Field

[0001] This utility model relates to the field of forging machinery technology, and in particular to a forming mold for complex flange forgings. Background Technology

[0002] Flanges are common connecting components in piping engineering, and their forging production typically requires the use of specialized forming dies. Forging forming dies, especially those used for forming complex flanges, usually include an upper die and a lower die (such as a flange die). The blank is shaped by the forging motion of the upper die.

[0003] In actual production, in order to adapt to flange forgings of different specifications or complex shapes, it is often necessary to change the mold frequently. Most existing methods of fixing the upper mold rely on large bolts or manual pressure plates for locking. This method is cumbersome to operate during disassembly and installation, requires a lot of manpower and time, and results in long equipment downtime and low production efficiency.

[0004] Furthermore, the reliability of manual locking is inconsistent and the level of automation is low, failing to meet the demands of modern forging production lines for efficient and rapid die changing. Therefore, designing a forming die that enables rapid, automatic, and reliable upper die changing is a problem urgently needing to be solved by those skilled in the art. Thus, this invention proposes a complex flange forging forming die to address the shortcomings of existing technologies. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a complex flange forging forming die, which aims to improve the problems of existing complex flange forging forming dies, such as reliance on manual locking during upper die replacement, cumbersome operation, low automation, and time and labor consumption.

[0006] This utility model provides a complex flange forging forming mold, including: a load-bearing plate, a top plate, a load-bearing column, a moving plate, a drive mechanism, a fixed plate, an upper mold, a flange mold, an ejection mechanism, and a fixing component.

[0007] The top plate is positioned above the load-bearing plate, the load-bearing column is vertically connected between the load-bearing plate and the top plate, and the movable plate is slidably connected to the load-bearing column. The driving mechanism includes a second hydraulic cylinder mounted on the top plate, which drives the movable plate to move.

[0008] The fixed plate is fixedly connected to the bottom of the movable plate, the upper mold is disposed below the fixed plate, and the flange mold is disposed on the load-bearing plate.

[0009] The ejection mechanism is located inside the load-bearing plate and includes a hydraulic cylinder, a wedge block, and a wedge block. The hydraulic cylinder drives the wedge block to move horizontally, and the wedge block drives the wedge block to move vertically. The wedge block is used to eject the flange mold.

[0010] Furthermore, the fixing component is mounted on the fixing plate. The fixing component includes a pneumatic push rod, a rotating column, and a rotating plate. The pneumatic push rod is used to drive the rotating column to rotate, and the rotating column drives the rotating plate to rotate, so as to achieve the locking or releasing of the upper mold.

[0011] Preferably, the second hydraulic cylinder of the driving mechanism is fixed to the bottom of the top plate, and the output end of the second hydraulic cylinder is connected to the moving plate to provide a stable driving force for the forging stroke.

[0012] Preferably, the ejection mechanism further includes a protective plate, which has a guide structure for guiding the horizontal sliding of the first inclined block and the vertical sliding of the second inclined block.

[0013] Furthermore, to ensure accurate guidance, the protrusion at the bottom of the protective plate engages with the groove at the bottom of the first inclined block, and the side protrusion of the second inclined block engages with the groove on the inner side of the protective plate.

[0014] Preferably, the fixing component further includes a circular locking block and a locking bead. The circular locking block is connected between the output end of the pneumatic push rod and the rotating column, and the locking bead is embedded in a groove inside the rotating column. Through the cooperation structure, the linear motion of the pneumatic push rod is converted into the rotational motion of the rotating column.

[0015] Preferably, as a means of protecting the internal structure of the fixing component, it further includes a sleeve, which is fitted around the pneumatic push rod, the circular locking block, and the rotating column.

[0016] Preferably, the pneumatic push rod and the rotating column of the fixed assembly are mounted on the fixed plate, forming the mounting base for the mold changing actuator.

[0017] Preferably, the fixing component further includes a pad, which is fixed to the fixing plate for auxiliary support or positioning.

[0018] This utility model has the following beneficial effects: 1. This utility model, by setting up an ejection mechanism, uses a hydraulic cylinder to drive a slant block to move horizontally, and the slant block pushes a slant block to move vertically through the inclined surface. The movement trajectory of the two slant blocks is guided by a protective plate, converting the horizontal thrust into a powerful vertical ejection force. This solves the problems of difficult ejection and demolding of forgings after forming, complex structure, or insufficient ejection force in the prior art, and achieves the technical effect of stable ejection, compact structure, and large ejection force.

[0019] 2. This utility model, by setting a fixed component, uses a pneumatic push rod to drive a rotating column, and converts linear motion into rotational motion through the cooperation of the locking ball and the sliding groove inside the rotating column, thereby driving the rotating plate to rotate to lock or release the upper mold. This solves the problems of manual locking, cumbersome operation, low automation and time and labor consumption when changing the upper mold in the prior art, and achieves the technical effect of fast and automated locking and releasing of the upper mold, improving the replacement efficiency.

[0020] 3. This utility model, by setting up a driving mechanism, uses a hydraulic cylinder to drive the moving plate and make the moving plate slide precisely along the load-bearing column. The structure is well-matched and solves the problem that the moving parts are prone to deflection due to the huge pressure during the forging process, which affects the forging accuracy. It achieves the technical effect of overall structural stability, precise guidance, and ensuring forging quality. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Example: Refer to Figures 1 to 4 This utility model provides a complex flange forging forming mold, which aims to solve the problems of low automation in upper mold replacement, insufficient locking reliability, and complex or inefficient forging ejection structure in the prior art.

[0024] like Figure 1 As shown, the system includes a load-bearing plate 1 and a top plate 6 disposed above the load-bearing plate 1; a load-bearing column 5 is vertically connected between the load-bearing plate 1 and the top plate 6; the load-bearing plate 1 is used to support the lower structure of the mold and the forging pressure, the top plate 6 is used to install the drive mechanism 7, and the load-bearing column 5 is used to support the top plate 6 and provide guidance for the movable plate 3; the movable plate 3 is slidably connected to the load-bearing column 5; the drive mechanism 7 includes a second hydraulic cylinder 71 installed at the bottom of the top plate 6, the output end of the second hydraulic cylinder 71 is connected to the movable plate 3, and the second hydraulic cylinder 71 drives the movable plate 3 to move; a fixed plate 72 is fixedly connected to the bottom of the movable plate 3; an upper mold 73 is disposed below the fixed plate 72; and a flange mold 25 is disposed on the load-bearing plate 1.

[0025] Reference Figure 1 and Figure 2 The ejection mechanism 2 includes a hydraulic cylinder 22, a first inclined block 23, and a second inclined block 24. The hydraulic cylinder 22 drives the first inclined block 23 to move horizontally, and the inclined surface of the first inclined block 23 pushes the second inclined block 24 to move vertically. The second inclined block 24 is used to eject the flange mold 25 upwards. The ejection mechanism 2 also includes a protective plate 21. The protective plate 21 has a guide structure for guiding the horizontal sliding of the first inclined block 23 and the vertical sliding of the second inclined block 24. Specifically, the convex groove at the bottom of the protective plate 21 engages with the groove at the bottom of the first inclined block 23 to ensure the horizontal reciprocating sliding of the first inclined block 23, and the convex groove on the side of the second inclined block 24 engages with the groove on the inner side of the protective plate 21 to ensure the vertical sliding of the second inclined block 24. This double-inclined block structure converts the horizontal thrust of the hydraulic cylinder 22 into a stable and powerful vertical ejection force. Reference Figure 1 , Figure 3 and Figure 4The fixing assembly 4 includes a pneumatic push rod 43, a rotating column 45, and a rotating plate 46. The pneumatic push rod 43 and the rotating column 45 are mounted on the fixing plate 72. The pneumatic push rod 43 drives the rotating column 45 to rotate, and the rotating column 45 drives the rotating plate 46 to rotate. The rotating plate 46 rotates to lock or release the upper mold 73, thereby realizing the quick replacement of the upper mold 73. The fixing assembly 4 also includes a circular locking block 44 and a locking ball 47. The circular locking block 44 is connected to the output end of the pneumatic push rod 43 and the rotating plate 46. Between the columns 45, the retaining bead 47 is embedded in the sliding groove inside the rotating column 45. When the pneumatic push rod 43 pushes the circular retaining block 44 to make the rotating column 45 move linearly, the cooperation between the retaining bead 47 and the sliding groove causes the rotating column 45 to rotate. The fixing component 4 also includes a sleeve 41, which is sleeved on the outer periphery of the pneumatic push rod 43, the circular retaining block 44 and the rotating column 45 to protect the internal components. The fixing component 4 also includes a pad 42, which is fixed on the fixing plate 72.

[0026] The hydraulic cylinder 71 of the drive mechanism 7 is fixed to the bottom of the top plate 6, and the output end of the hydraulic cylinder 71 is connected to the moving plate 3.

[0027] Reference Figure 2 The ejection mechanism 2 also includes a protective plate 21, which has a guide structure for guiding the horizontal sliding of the first inclined block 23 and the vertical sliding of the second inclined block 24. More specifically, the protrusion at the bottom of the protective plate 21 is engaged with the groove at the bottom of the first inclined block 23, and the side protrusion of the second inclined block 24 is engaged with the groove on the inner side of the protective plate 21.

[0028] Reference Figure 4 The fixing component 4 also includes a circular locking block 44 and a locking bead 47. The circular locking block 44 is connected between the output end of the pneumatic push rod 43 and the rotating column 45, and the locking bead 47 is embedded in the sliding groove inside the rotating column 45. Furthermore, the fixing component 4 also includes a sleeve 41, which is sleeved on the outer periphery of the pneumatic push rod 43, the circular locking block 44 and the rotating column 45.

[0029] The pneumatic push rod 43 and rotating column 45 of the fixed assembly 4 are mounted on the fixed plate 72; further, the fixed assembly 4 also includes a pad 42, which is fixed on the fixed plate 72.

[0030] The implementation principle of this application embodiment is as follows: During the forging process, the hydraulic cylinder 71 in the drive mechanism 7 is started. The hydraulic cylinder 71 is fixed to the bottom of the top plate 6, and its output end is connected to the moving plate 3. The moving plate 3 is driven to slide down along the load-bearing column 5. The load-bearing column 5 ensures that the moving plate 3 is stable and does not deviate during the movement. The moving plate 3 drives the fixed plate 72 fixed to its bottom and the upper mold 73 fixed by the fixed component 4 to move down synchronously. The upper mold 73 forges the workpiece in the flange mold 25 set on the load-bearing plate 1.

[0031] When the upper mold 73 needs to be replaced, the fixing component 4 installed on the fixing plate 72 is activated. The pneumatic push rod 43 pushes the circular locking block 44, which in turn pushes the rotating column 45 to produce linear motion. When the rotating column 45 moves linearly, the locking ball 47 embedded in the sliding groove inside the rotating column 45 cooperates with the sliding groove, forcing the rotating column 45 to rotate. The rotating column 45 drives the rotating plate 46 to rotate, thereby releasing the jamming state of the upper mold 73, so as to facilitate the replacement of the new upper mold 73. The reverse operation can lock it. The sleeve 41 is sleeved on the outer periphery of the pneumatic push rod 43, the circular locking block 44 and the rotating column 45 for protection. The pad 42 is fixed on the fixing plate 72.

[0032] After forging is completed, the ejection mechanism 2 set in the load-bearing plate 1 is activated. The hydraulic cylinder 22 drives the inclined block 23 to move horizontally. The groove at the bottom of the protective plate 21 engages with the groove at the bottom of the inclined block 23, guiding the inclined block 23 to slide horizontally. When the inclined block 23 slides horizontally, it pushes the inclined block 24 through its inclined surface. At the same time, the side groove of the inclined block 24 engages with the groove on the inner side of the protective plate 21, guiding the inclined block 24 to move only vertically upward. When the inclined block 24 rises vertically, it ejects the flange mold 25, completing the demolding.
