Description

Technical Field

[0001] The invention relates to the technical field of hardware forging, in particular to a hardware iron sheet forging device. Background Art

[0002] Forging is a processing method that uses a forging machine to apply pressure to a metal blank to cause it to undergo plastic deformation in order to obtain forgings with certain mechanical properties, shapes and sizes. It is one of the two major components of forging (forging and stamping). Forging can eliminate defects such as cast porosity produced during the metal smelting process and optimize the microstructure. At the same time, since the complete metal flow lines are preserved, the mechanical properties of forgings are generally better than those of castings of the same material. For important parts of related machinery with high loads and severe working conditions, forgings are mostly used, except for simpler shapes that can be made of rolled plates, profiles or welded parts.

[0003] Traditional hardware iron sheet forging devices have certain limitations in forging specifications, forging area and forging balance. The forging molds are also relatively simple and cannot be flexibly adjusted. Forging molds are mostly one-piece designs. If you want to forge hardware iron sheets of other shapes or sizes, you need to disassemble the entire forging mold for replacement, which takes a lot of time to change the mold and affects production efficiency.

[0062] A short pin 631 is installed on the top of the guide plate 63 near the end body 61, and a horizontal screw rod 632 is connected to the side of the guide plate 63 near the end body 61. The guide plate 63 is threadedly connected to the end body 61 through the horizontal screw rod 632. At the same time, the guide plate 63 can also be installed with the end body 61 through the short pin 631. Through this two-phase assembly method of the guide plate 63 and the end body 61, the assembly structural strength of the guide plate 63 and the end body 61 in the horizontal and vertical planes is strengthened, which can resist the impact force when forging hardware iron sheets.

[0063] When it is necessary to forge a longer piece of hardware iron, the hydraulic tension rod 64 can be used to drive the T-shaped bottom die 71 to extend to the end away from the upper die body 41. At this time, the T-shaped bottom die 71 moves on the guide plate 63 to the side away from the upper die body 41, moving a length unit of the thickness of the filling plate 51. At this time, a plate cavity space of the thickness of the filling plate 51 is vacated between the end body 74 and the upper die body 41; then the torsion motors 52 on the front and rear sides are activated, and the torsion motor 52 on the rear side drives the side stand plate 53 on the rear side of the filling plate 51 to rotate counterclockwise The torsion motor 52 on the front side drives the side stand plate 53 on the front side of the filling plate 51 to rotate clockwise, so that the barbed teeth 54 on the side stand plates 53 on the front and rear sides of the filling plate 51 are misaligned with the side waist teeth 46 on the inner side of the side waist cavity 45, ensuring that the side stand plates 53 on the front and rear sides of the filling plate 51 can smoothly perform vertical falling movement inside the side waist cavity 45, and then the electromagnetic suction folding frame 44 releases the magnetic attraction on the top of the first filling plate 51 close to the electromagnetic suction folding frame 44, so that the filling plate 51 that is magnetically mounted with the electromagnetic suction folding frame 44 is released. The mold 5 falls as a whole to the bottom of the side waist cavity 45, so that the bottom of the filling plate 51 is flush with the bottom of the upper mold body 41 and the end body 74. At this time, the bottom of the top seat block 55 is just above the side waist cavity 45 and against the top of the upper mold body 41. Then, the torsion motor 52 is activated again to rotate the side upright plates 53 on the front and rear sides of the filling plate 51 to the initial position, that is, the filling plate 51 and the two side upright plates 53 on the front and rear sides are located in the same horizontal plane. At this time, the barbed teeth 54 on the two side upright plates 53 are aligned with the inner side of the side waist cavity 45. The side waist teeth 46 are hooked and engaged, and then the magnetic attraction of the electromagnetic ring body 56 to the steel ball 57 is released. Under the guidance of the semi-spherical cavity 58, the steel ball 57 falls vertically and is stuck between the semi-circular groove 47 and the semi-spherical cavity 58. Through the clamping and limiting of the steel ball 57 and the engagement of the barbed teeth 54 with the side waist teeth 46, the filling plate 51 is automatically supplemented and assembled in the plate cavity space as a whole, thereby realizing the automatic adjustment and change of the upper mold assembly in the left and right length directions, thereby realizing the forging processing of hardware iron sheets of different lengths by the upper mold assembly.

[0064] When it is necessary to reduce and adjust the transverse forging length, the steel ball 57 can be first pushed out vertically from the semicircular groove 47 by the electric push rod 411, and the steel ball 57 can be pushed back to the inside of the electromagnetic ring body 56 along the semicircular spherical cavity 58. The electromagnetic ring body 56 magnetically attracts the steel ball 57, and then the torsion motor 52 drives the front and rear side vertical plates 53 to rotate in opposite directions until the barb teeth 54 and the side waist teeth 46 are staggered, ensuring that the filling plate 51 as a whole can move up and down inside the side waist cavity 45 with the help of the side vertical plates 53; then the air guide pipe head 66 is connected to the high-pressure air pipe, and the high-pressure air flow is sprayed from the diagonal nozzle 48, and the high-pressure air column formed by the high-pressure air in the narrow space of the side waist cavity 45 is used to move the filling plate 51 as a whole to The top of the filling plate 51 is magnetically attached to the electromagnetic folding frame 44 by reusing the magnetic attraction of the electromagnetic ring body 56 and the electromagnetic folding frame 44; at the same time when the filling plate 51 is pushed upward as a whole, the hydraulic tension rod 64 is activated in real time to drive the T-shaped bottom die 71 to retract a length unit of the thickness of the filling plate 51, so that the T-shaped bottom die 71 is attached to the upper die body 41 and approaches it, so that after the filling plate 51 is magnetically attached to the electromagnetic folding frame 44, the end body 74 is retracted and supplemented in the plate cavity space, and the bottom die assembly 7 provides shielding and support for the bottom of the filling plate 51 again, thereby realizing the automatic reduction and adjustment of the lateral length of the upper die assembly, and realizing the adaptive adjustment forging processing of short hardware iron sheets.

[0065] The third embodiment is based on the first and second embodiments. Fig.16 As shown, the left and right sides of the upper mold assembly 4 are symmetrically installed with bottom mold assemblies 7, and the bottom mold assembly 7 is specifically installed on the side of the filling module 5 away from the upper mold assembly 4. The bottom mold assembly 7 is used to extend the length of the left and right sides of the upper mold assembly 4. The bottom mold assembly 7 includes a T-shaped bottom mold 71 installed on the side of the filling plate 51 away from the upper mold body 41. The bottom of the T-shaped bottom mold 71 is slidably mounted on the guide plate 63, and the guide plate 63 is used to provide support and guidance for the bottom of the T-shaped bottom mold 71.

[0066] A side of the T-shaped bottom mold 71 close to the filling plate 51 is fixedly connected to a stepped body 72, and a side of the stepped body 72 close to the upper mold body 41 is assembled with a thickened mounting plate 73 and an end body 74. Stud screws 75 are installed on the four corners of the thickened mounting plate 73. The thickened mounting plate 73 is threadedly installed between the end body 74 and the stepped body 72 through the stud screws 75. The T-shaped bottom mold 71 is telescopically installed with the end body 61 through a hydraulic tension rod 64. The stepped body 72, the thickened mounting plate 73 and the end body 74 jointly block the bottom of the filling module 5.

[0067] During the forging of the metal iron sheet using the upper die assembly, the guide plate 63 is not only a limiting guide for the T-shaped bottom die 71, but also an auxiliary reinforcement structure that cooperates with the top plate 43 to tightly assemble the side die assembly 6 and the bottom die assembly 7 on the upper die assembly 4, so that even if the bottom die assembly 7 is installed at a side position away from the upper die assembly 4, it can still remain in the forging plane working together with the upper die assembly 4 to perform balanced impact on the metal iron sheet, thereby compensating for the shortcoming of insufficient forging force on the left and right sides of the hardware iron sheet due to the extension of the length of the upper die assembly, and ensuring that no matter how the length of the upper die assembly is adjusted and changed, the bottom of the upper die assembly has a balanced forging effect on the hardware iron sheet.

[0068] During the use of the upper die assembly, the assembly of the filling module 5, the side die assembly 6 and the bottom die assembly 7 on both sides of the upper die assembly 4 can be specifically controlled according to the length specification range of the hardware iron sheet to be forged. Specifically, the specific number of the filling modules 5 installed between the upper die assembly 4 and the bottom die assembly 7 can be increased or decreased according to the specification requirements of the forged hardware iron sheet raw materials, the number of thickening blocks 62 installed between the end body 61 and the upper die body 41 can be increased or decreased, and the number of thickening plates 73 installed between the step body 72 and the end body 74 can be increased or decreased, so as to fundamentally improve the effective forging range of the upper die assembly for the hardware iron sheet in the horizontal length direction.

[0069] The upper die assembly is composed of an upper die component 4, a filling die 5, a side die component 6 and a bottom die component 7, thereby realizing a modular assembly structure design of a multi-module forging die assembly, facilitating the loading and unloading and adjustment of the forging die, reducing the die changing time and improving the production efficiency; it can also be flexibly expanded as required to meet the production needs of hardware iron sheets of different specifications; by expanding the forging area at the bottom of the upper die assembly, it is also possible to flexibly and efficiently forge hardware iron sheets of different sizes and shapes.

[0070] At the same time, the air guide pipe head 66 is used to connect the high-pressure air pipe, so that the high-pressure airflow can flow inside the plug joint 68, the connecting head 410, and the connecting hole valve 622, and the high-pressure airflow can be ejected from the diagonal nozzle 48, the L-shaped nozzle 49, the first I-shaped nozzle 69 and the second I-shaped nozzle 623. During the forging process of the upper mold assembly on the hardware iron sheet, the internal parts of each module structure of the upper mold assembly can be cooled and dissipated in real time, and real-time cooling of the interior of the upper mold assembly can be achieved.

[0071] Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field and related fields without creative work should fall within the scope of protection of the present invention. The structures, devices and operating methods not specifically described and explained in the present invention are implemented according to the conventional means in the field unless otherwise specified and limited.
