Description

Technical Field

[0001] The present invention belongs to the technical field of pliers processing, and specifically relates to a forging and forming machine for pliers processing. Background Art

[0002] When producing tool pliers, they are mainly processed and formed by forging. Hot die forging is a type of forging process. After heating a metal blank to a temperature higher than the recrystallization temperature of the material, a forging press and a die are used to plastically form the metal blank into the shape and size of a forging.

[0003] Traditional forging and forming machines usually only have one working position. When forging and producing tool pliers, first place a high-temperature blank in the forging die at this working position, and it is forged and formed by a punching die hammer. Then take out the forged tool pliers forging, and only then can the next high-temperature blank be put in to repeat the above forging and forming work. Since the forging and forming machine with a single working position cannot put another high-temperature blank to be forged while forging, the working efficiency of forging and forming is greatly reduced. Although multi-station forging and forming machines have also appeared on the market currently, the existing multi-station forging and forming machines still have the problem of poor synchronism between forging and forming and placing high-temperature blanks.

[0019] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments; based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0020] It should be noted that the words "front", "rear", "left", "right", "upper" and "lower" used in the following description refer to the directions in the drawings, and the words "inner" and "outer" respectively refer to the directions towards or away from the geometric center of a specific component.

[0021] Refer to Figures 1-5 , a forging and forming machine for pliers processing provided in this embodiment includes: Forging oil cylinder 1; Pushing plate 2, connected to the free end of the forging oil cylinder 1, and the pushing plate 2 is configured to be driven by the forging oil cylinder 1 to move up and down; Transmission plate 3, movably arranged above the pushing plate 2. Corresponding inclined pushing surfaces are provided on the upper surface of the pushing plate 2 and the lower surface of the transmission plate 3. The transmission plate 3 is driven by the inclined pushing surface of the pushing plate 2 to move in the horizontal and vertical directions. A driving rack 4 is provided on the side wall of the transmission plate 3 away from the pushing plate 2; Driving gear 5, rotatably arranged on one side of the driving rack 4. When the driving rack 4 moves close to the driving gear 5 along with the transmission plate 3, it is configured to mesh with the driving gear 5. When the driving rack 4 meshes with the driving gear 5 and moves along the vertical direction along with the transmission plate 3, the driving gear 5 is driven to rotate; Synchronous transmission mechanism 6, connected to the driving gear 5; Station adjustment rotating shaft 7, configured to be driven by the synchronous transmission mechanism 6 to perform intermittent rotation at a fixed angle. When the station adjustment rotating shaft 7 performs intermittent rotation at a fixed angle, the position of the forging station is adjusted; Wherein, when the pushing plate 2 is driven by the forging oil cylinder 1 to rise, the pushing plate 2 drives the transmission plate 3 to move horizontally first and then rise vertically through the inclined pushing surface. When the pushing plate 2 is driven by the forging oil cylinder 1 to descend, the pushing plate 2 drives the transmission plate 3 to descend vertically first and then move horizontally through the inclined pushing surface.

[0022] It should be noted that the thickness of the pushing plate 2 is less than that of the transmission plate 3. When the pushing plate 2 rises or descends under the action of the forging oil cylinder 1, the inclined pushing surface of the pushing plate 2 slides along the inclined pushing surface of the transmission plate 3. Specifically, as the pushing plate 2 rises, the transmission plate 3 receives a horizontal pushing force applied by the pushing plate 2 towards the driving gear 5 and a rising pushing force in the vertical direction. The transmission plate 3 moves horizontally to engage with the driving gear 5, and during the process of the transmission plate 3 rising vertically, the driving gear 5 is driven by the driving gear 5 to rotate. The driving gear 5 drives the station adjustment rotating shaft 7 to rotate through the synchronous transmission mechanism 6.

[0023] Specifically, referring to Figure 4 , in this embodiment, a workbench 8 is fixedly provided on the station adjustment rotating shaft 7, and a plurality of forging dies 9 are provided on the workbench 8. A punching die hammer 10 is fixedly provided at one end of the pushing plate 2 away from the transmission plate 3. The forging die 9 below the punching die hammer 10 corresponds to the forging and forming station, and the forging dies 9 on both sides of the forging and forming station correspond to the loading station and the unloading station respectively.

[0024] As a specific embodiment, three groups of forging dies 9 are evenly arranged on the workbench 8. The three groups of forging dies 9 correspond to the loading station, the forging and forming station, and the unloading station respectively. The loading of the high-temperature metal blank of the pliers is completed at the loading station, the forging and forming of the rough blank of the pliers is completed at the forging and forming station, and the rough blank of the pliers after forging and forming is unloaded at the unloading station. Through the setting of the three stations, the blank loading, forging and forming, and unloading are carried out simultaneously, improving the forging and forming processing efficiency of the pliers. In this embodiment, to ensure that the three groups of forging dies 9 can alternately rotate accurately below the punching die hammer 10 with the rotation of the station adjustment rotating shaft 7, the number of teeth of the driving rack 4 is set to 1 / 3 of the number of teeth of the driving gear 5. The station adjustment rotating shaft 7 rotates 120° each time. If other groups of forging dies 9 are set, the rotation angle of the station adjustment rotating shaft 7 each time is controlled by adjusting the ratio of the number of teeth of the driving rack 4 and the driving gear 5.

[0025] During operation, when the forging cylinder 1 drives the die hammer 10 to fall, the die hammer 10 cooperates with the forging die 9 at the forging and forming station to forge the blank into a rough blank of pliers. When the forging cylinder 1 drives the die hammer 10 to rise, through the meshing of the driving rack 4 and the driving gear 5 and the transmission of the synchronous transmission mechanism 6, the driving station adjustment rotating shaft 7 drives the workbench 8 to rotate by a corresponding angle, so that multiple forging dies 9 rotate in turn to the forging and forming station below the die hammer 10, realizing the continuous processing of pliers forging and forming; during the whole process, the rotation of the station adjustment rotating shaft 7 to adjust the positions of multiple forging dies 9 is synchronized with the contraction action of the forging cylinder 1, ensuring the synchronism of the plier body forging and forming production of the forging and forming machine.

[0026] Specifically, referring to Figure 4 and Figure 5 , in this embodiment, the synchronous transmission mechanism 6 includes a first transmission shaft 11, a second transmission shaft 12 and a third transmission shaft 13. The second transmission shaft 12 is arranged parallel to the first transmission shaft 11, and the third transmission shaft 13 is vertically arranged between the second transmission shaft 12 and the station adjustment rotating shaft 7; The driving gear 5 is fixedly arranged on the first transmission shaft 11. A set of belt pulleys are respectively fixedly arranged on the first transmission shaft 11 and the second transmission shaft 12. A driving belt 14 is sleeved on the two sets of belt pulleys. Under the action of the driving belt 14, the first transmission shaft 11 drives the second transmission shaft 12 to rotate. A first driving bevel gear 15 is fixedly arranged on the second transmission shaft 12. First driven bevel gears 16 and a second driving bevel gear 17 are respectively fixedly arranged at both ends of the third transmission shaft 13. A second driven bevel gear 18 is fixedly arranged on the station adjustment rotating shaft 7. The first driving bevel gear 15 and the first driven bevel gear 16 are meshed. Through the meshing of the first driving bevel gear 15 and the first driven bevel gear 16, the second transmission shaft 12 drives the third transmission shaft 13 to rotate. The second driving bevel gear 17 and the second driven bevel gear 18 are meshed. Through the meshing of the second driving bevel gear 17 and the second driven bevel gear 18, the third transmission shaft 13 drives the station adjustment rotating shaft 7 to rotate.

[0027] During operation, when the forging cylinder 1 contracts and drives the push plate 2 to rise, the push plate 2 exerts a horizontal driving force on the transmission plate 3 towards the driving gear 5 to make the driving rack 4 and the driving gear 5 meshed. At the same time, the push plate 2 exerts an upward driving force on the transmission plate 3. When the transmission plate 3 drives the driving rack 4 to move upward, the driving rack 4 meshes with the driving gear 5 to drive the driving gear 5 to rotate. Under the driving and transmission action of the driving gear 5 and the synchronous transmission mechanism 6, the driving station adjustment rotating shaft 7 rotates by a certain angle, thereby driving multiple groups of forging dies 9 to alternately rotate below the die hammer 10, and forging and forming the high-temperature metal blank in the forging die 9 when the die hammer 10 is driven by the forging cylinder 1 to descend.

[0028] Specifically, referring to Figure 2and Figure 3 In this embodiment, a forging and forming machine for pliers processing further includes a bracket 19 and a reset mechanism. The forging oil cylinder 1 is arranged on the bracket 19. The reset mechanism includes a longitudinal reset mechanism 20 and a transverse reset mechanism. The longitudinal reset mechanism 20 is arranged on the bracket 19. An installation plate 21 is arranged on the longitudinal reset mechanism 20. A fixed plate 30 is arranged on the installation plate 21. The transverse reset mechanism is arranged on the fixed plate 30. The transmission plate 3 is connected to the transverse reset mechanism. By setting the longitudinal reset mechanism 20, it is ensured that the installation plate 21 moves stably in the vertical direction. By setting the transverse reset mechanism, it is ensured that the transmission plate 3 and the installation plate 21 move synchronously and stably in the vertical direction. And by setting the transverse reset mechanism, it can also be ensured that the transmission plate 3 slides horizontally below the installation plate 21.

[0029] Specifically, referring to Figure 2 and Figure 3 In this embodiment, a limiting chute 22 is arranged on the lower surface of the installation plate 21, and a limiting projection 23 is arranged on the upper surface of the transmission plate 3. The limiting projection 23 is engaged and slidably arranged in the limiting chute 22. By setting the limiting projection 23 and the limiting chute 22, the horizontal movement range of the transmission plate 3 in the transverse direction is limited. Specifically, when the limiting projection 23 slides along the limiting chute 22 to one end far from the transverse reset mechanism, the driving rack 4 just meshes with the driving gear 5; the longitudinal cross-sections of the limiting chute 22 and the limiting projection 23 are both T-shaped. By setting the T-shaped limiting chute 22 and the limiting projection 23, it is ensured that the installation plate 21 and the transmission plate 3 rise and fall synchronously when moving in the vertical direction.

[0030] During operation, when the forging oil cylinder 1 contracts and drives the push plate 2 to rise, the push plate 2 exerts forces in the horizontal and vertical directions on the transmission plate 3: Under the action of the horizontal force, the transmission plate 3 drives the limiting projection 23 to slide horizontally along the limiting chute 22. When the limiting projection 23 slides to one end of the limiting chute 22, limited by the limiting chute 22, the transmission plate 3 no longer moves in the horizontal direction. At this time, the transmission plate 3 drives the driving rack 4 to mesh with the driving gear 5. After that, the transmission plate 3 only rises in the vertical direction and no longer moves in the horizontal direction; After the driving rack 4 meshes with the driving gear 5, during the process of the transmission plate 3 rising under the action of the vertical force, the transmission plate 3 drives the driving rack 4 to mesh with the driving gear 5 to drive the driving gear 5 to rotate, thereby driving the station adjustment rotating shaft 7 to rotate at a fixed angle.

[0031] Specifically, referring to Figure 3, in this embodiment, the reset mechanism includes a reset sliding cylinder 24, a reset sliding rod 25 and a reset spring 26. The reset sliding cylinder 24 is fixedly arranged, the reset sliding rod 25 is slidably arranged in the reset sleeve, and the reset spring 26 is sleeved on the reset sliding cylinder 24 and the reset sliding rod 25. The cooperation of the reset sliding cylinder 24 and the reset sliding rod 25 ensures the stability of the movement of the transmission plate 3 in the horizontal and vertical directions. And when the external force is removed, the reset spring 26 drives the driving transmission plate 3 to automatically reset to the initial state.

[0032] It should be noted that the initial state of the transmission plate 3 is: away from the driving gear 5 in the horizontal direction and away from the top end of the bracket 19 in the vertical direction.

[0033] Specifically, refer to Figure 3 and Figure 4 , in this embodiment, the reset sliding cylinder 24 of the longitudinal reset mechanism 20 is fixedly arranged on the bracket 19, the reset sliding rod 25 of the longitudinal reset mechanism 20 is fixedly connected to the mounting plate 21, and the two ends of the reset spring 26 of the longitudinal reset mechanism 20 are respectively connected to the bracket 19 and the mounting plate 21; The reset sliding cylinder 24 of the transverse reset mechanism is fixedly arranged on the fixed plate 30, the reset sliding rod 25 of the transverse reset mechanism is fixedly connected to the transmission plate 3, and the two ends of the reset spring 26 of the transverse reset mechanism are respectively connected to the fixed plate 30 and the transmission plate 3.

[0034] Specifically, refer to Figure 3 , in this embodiment, an electromagnet 27 is arranged on the bracket 19, an iron plate is arranged on the mounting plate 21, a proximity sensor 28 is arranged on the bracket 19, and the proximity sensor 28 is electrically connected to the electromagnet 27 through a controller; a pull-down plate 29 is arranged on the push plate 2, the upper end of the pull-down plate 29 is located above the mounting plate 21, and the pull-down plate 29 is configured to move vertically relative to the mounting plate 21 along with the push plate 2.

[0035] During operation, when the forging oil cylinder 1 contracts and drives the push plate 2 to rise, by applying a force to the transmission plate 3, the mounting plate 21 is driven to move upward. The mounting plate 21 approaches the proximity sensor 28, the proximity sensor 28 senses the position of the mounting plate 21 and transmits a signal to the controller, and the controller controls the electromagnet 27 to be energized to adsorb the iron plate on the mounting plate 21; When the forging oil cylinder 1 extends and drives the push plate 2 to descend, the push plate 2 slides along the inclined pushing surface of the transmission plate 3, releasing the horizontal force applied by the push plate 2 to the transmission plate 3 towards the driving gear 5. Under the magnetic adsorption of the electromagnet 27 on the mounting plate 21, the transmission plate 3 only slides horizontally under the action of the transverse reset mechanism and cannot descend vertically. When the transmission plate 3 moves horizontally, it drives the driving rack 4 away from the driving gear 5; Next, as the pushing plate 2 descends, when the pulling plate 29 descends to contact the mounting plate 21, a downward acting force is exerted on the mounting plate 21 during the descent of the pulling plate 29. The downward acting force of the pulling plate 29 is greater than the magnetic adsorption force of the electromagnet 27. Under the pulling action of the pulling plate 29, the mounting plate 21 is driven to separate from the electromagnet 27. And since the mounting plate 21 moves away from the proximity sensor 28, the electromagnet 27 is powered off. Under the action of the longitudinal reset mechanism 20, the transmission plate 3 resets in the vertical direction. And during the process of the transmission plate 3 resetting in the vertical direction, since the driving rack 4 moves away from the driving gear 5, the driving gear 5 is no longer driven to rotate, thereby preventing the forging cylinder 1 from extending to drive the die hammer 10 to descend and drive the driving gear 5 to rotate and reset.

[0036] It should be noted that in this text, relational terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the term "comprising", "including" or any other variant thereof is intended to cover non-exclusive inclusion, so that a process, method, material or device comprising a series of elements not only includes those elements, but also includes other elements not expressly listed, or further includes elements inherent to such process, method, material or device.

[0037] Although the embodiments of the present invention have been shown and described, it will be understood by those of ordinary skill in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention.
