Description

Technical Field

[0001] The invention relates to the technical field of forging, in particular to an automatic hot forging die for automobile parts. Background Art

[0002] Hot forging is a forging process above the metal recrystallization temperature, also known as hot die forging. In this process, the metal undergoes violent deformation flow in a high temperature environment, and the contact time between the forging and the die is relatively long. The main purpose of hot forging is to improve the plasticity of the metal through high temperature, reduce the deformation resistance of the metal, and change the cast structure of the steel ingot, thereby improving the mechanical properties and reliability of the forging.

[0003] For example, the publication number is: CN220805367U, and the name is: "A forging die", which includes a lower die and an upper die, the lower die is installed on the bottom plate, and the lower die is provided with a cavity, and the lower die is provided with a buffer structure. The buffer structure is provided on the lower die, and during the forging process, as the lifting plate descends, the buffer structure can play a role of buffering protection, avoiding the lifting plate from directly hitting the lower die, ensuring that the lower die is less worn after long-term use, and reducing the use cost to a certain extent. A die-casting component is provided at the lower end of the upper die, and the die-casting component is used to contact the blank for forging. When the die-casting component is worn, it can be directly disassembled and replaced without the need to disassemble and replace the entire upper die, reducing the replacement cost, so that the upper die can be used for a long time, and together with the lower die, it can be ensured that the upper and lower dies can be replaced at one time after long-term use, without the need to be replaced separately, further reducing the replacement cost.

[0004] The shortcomings of the prior art, such as those mentioned above, are as follows: 1. During hot forging, it is usually necessary to manually place the blank into the die, and the cylinder forges the blank in the die so that the blank is deformed and formed. However, the hot forging efficiency is greatly reduced by manual loading and unloading. 2. After the blank is deformed by forging, adhesion will occur between the blank and the die, making it difficult to unload the forged product. Summary of the invention

[0005] The purpose of the present invention is to provide an automated hot forging die for automobile parts to solve the deficiencies in the above-mentioned prior art.

[0006] In order to achieve the above object, the present invention provides the following technical solution: an automated hot forging die for automobile parts, comprising:

[0014] At the forging station: the two mold bodies are abutted against each other to limit the blank, and the support plates are abutted against each other to support the blank;

[0015] During the blanking stroke: the rotating shaft rotates in the first direction, driving the forging head to move vertically upward and driving the turntable to rotate unidirectionally. First, each support plate slides radially along the positioning ring and moves away from each other, thereby canceling the support for the blank. Second, the two mold bodies move away from each other to cancel the clamping of the blank, so that the forged blank falls downward from the inside of the positioning ring to complete the blanking action;

[0016] During the mold closing stroke: the turntable continues to rotate, first making the support plates abut against each other, and then making the two mold bodies abut against each other;

[0017] At the loading station: the rotating shaft rotates in the second direction, driving the forging head to move vertically downward to forge the blank located at the forging station. At the same time, the material taking ring moves to the position of the material rack, so that the blank closest to the material taking ring end in the material rack passes through the material taking ring and freely falls, and lands between the two mold bodies of another mold.

[0018] Furthermore, a vertical plate is fixedly connected to the machine frame, the forging head is slidably connected to the vertical plate, a screw rod is rotatably connected to the machine frame, and the screw rod is threadedly connected to the forging head.

[0024] Furthermore, the through groove includes an opening and closing groove and an arc groove, and the opening and closing groove communicates with the arc groove.

[0025] Furthermore, the guiding frame is composed of a delay section and a moving section.

[0026] Furthermore, a torsion spring is arranged between the pawl and the rotating shaft.

[0028] 1. By rotating the rotating shaft, when the rotating shaft rotates in the first direction, it can drive the turntable to rotate in a one-way intermittent manner, so that each group of dies are sequentially located at the forging station; when the rotating shaft rotates in the second direction, on the one hand, it can drive the forging head to move down for forging operations, and on the other hand, through the abutting cooperation between the material taking ring and the blanking plate, the blank at the outermost end in the material rack can fall into the die, completing the feeding action and realizing automatic loading and unloading, greatly improving the hot forging efficiency.

[0029] 2. When the material taking ring abuts against the blanking plate, it drives the blanking plate to slide on the material rack. The blanking plate drives one end of the connecting rod to slide synchronously, and the other end of the connecting rod drives one end of the limiting rod to rotate, so that the other end of the limiting rod limits the other blanks, preventing the blank at the outermost end from failing to fall due to the elastic force of the first spring; at the same time, the first spring elastically supports each blank, so that each blank moves in the material rack and is sequentially located at the outermost end in the rack, preparing for the feeding operation.

[0043] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further introduced in detail below with reference to the accompanying drawings.

[0044] Please refer to Figures 1-10 , an automatic hot forging die for automobile parts provided by an embodiment of the present invention includes: a frame 1; a turntable 2, which is intermittently rotatably connected to the frame 1;

[0045] A forging head 3, which is vertically slidably connected to the frame 1; specifically, a vertical plate 31 is fixedly connected to the frame 1, the forging head 3 is slidably connected to the vertical plate 31, a screw rod 32 is rotatably connected to the frame 1, the screw rod 32 is screwed to the forging head 3, and the forging head 3 realizes vertical reciprocating movement on the frame 1 through the reciprocating rotation of the screw rod 32, so as to forge the blank.

[0046] In the embodiment of the present invention: multiple sets of molds 4, and the number of the molds 4 is four groups; each set of molds 4 includes a positioning ring 41 fixedly connected to the turntable 2, two mold bodies 42 are slidably connected to the turntable 2, the two mold bodies 42 are abutted and cooperated with each other, and a plurality of support plates 43 are slidably connected to the positioning ring 41, and the support plates 43 are abutted and cooperated with each other.

[0047] It can be understood that: before the blank is forged, its diameter is small, and a forging space is formed between the positioning ring 41, the two mold bodies 42 and the support plates 43. Therefore, the blank is located in the positioning ring 41 and supported by the support plates 43 before starting forging, and at this time, the function of the two mold bodies 42 is: to limit the diameter of the blank after forging; when the two mold bodies 42 are in an abutting state, the inner side wall of the mold body 42 coincides with the inner wall of the positioning ring 41.

[0048] Specifically, first abutting rods 421 are fixedly connected to both of the two mold bodies 42, and a first chute 21 for the two first abutting rods 421 to slide is opened on the turntable 2, as Figure 5As shown, a slider is fixedly connected to the die body 42, and a first abutting rod 421 is fixedly connected to the slider. By sliding the slider in the first chute 21, it can be ensured that the die body 42 does not rotate during the sliding process, avoiding the ineffective abutment of the two die bodies 42; a second abutting rod 431 is fixedly connected to each support plate 43, and a second chute 22 for the sliding of each second abutting rod 431 is provided on the turntable 2; it can be understood that both the first abutting rod 421 and the second abutting rod 431 penetrate and extend to the outside of the turntable 2.

[0049] More specifically, the mold 4 further includes a rotating plate 44 rotatably connected to the turntable 2. A through groove for the sliding abutment of each second abutting rod 431 is provided on the rotating plate 44, and two guiding frames 45 are fixedly connected to the rotating plate 44. The two first abutting rods 421 respectively slide and abut against the two guiding frames 45 in a one-to-one correspondence.

[0050] Among them, the through groove includes an opening and closing groove 441 and an arc groove 442, and the opening and closing groove 441 communicates with the arc groove 442.

[0051] Among them, the guiding frame 45 is composed of a delay section 451 and a motion section 452.

[0052] When the rotating plate 44 rotates, it can drive the guiding frame 45 to rotate synchronously. During the rotation, through the cooperation of the opening and closing groove 441, the second abutting rod 431, and the second chute 22, each support plate 43 can slide along the radial direction of the positioning ring 41 and move away from each other, thereby canceling the support for the blank; during this period, the first abutting rod 421 slides in the delay section 451, so that the two die bodies 42 remain stationary; the resulting effect is: by canceling the support of each support plate 43 for the blank, it is avoided that the blank adheres to the support plate 43. At the same time, as the support of the support plate 43 for the blank is canceled, it is also possible to prepare for the blanking of the blank and avoid the interference of the support plate 43 on the blanking process.

[0053] Immediately following the above, as the rotation progresses, the second abutting rod 431 slides in the arc groove 442, so that each support plate 43 remains in a state of being opened and separated from each other, and the first abutting rod 421 slides from the delay section 451 into the motion section 452, so that the two first abutting rods 421 move away from each other, thereby causing the two first abutting rods 421 to slide in the two first chutes 21 respectively, resulting in the two die bodies 42 moving away from each other to complete the mold opening action; it can be understood that through the limitation of the blank by the positioning ring 41, and as the two die bodies 42 move away from each other, they are separated from the blank, avoiding the blank adhering to the two die bodies 42; and when the mold opening action is completed, the blank will fall downward through the positioning ring 41 due to its own gravity to complete the blanking action.

[0054] Specifically, the specific rotation mode of the rotating plate 44 is as follows: A worm gear 46 is fixedly connected to the bottom of the rotating plate 44, a worm 47 is rotatably connected to the turntable 2, the worm gear 46 meshes with the worm 47, a gear 48 is fixedly connected to the worm 47, and a first rack 49 and a second rack 410 are fixedly connected to the frame 1. It can be understood that the teeth of the first rack 49 and the second rack 410 are arranged in opposite directions; the gear 48 meshes and cooperates with the first rack 49 and the second rack 410 respectively.

[0055] Through the gear 48 and the first rack 49 and the second rack 410, the rotating plate 44 can be driven to rotate forward and backward by the transmission of the worm gear 46 and the worm 47; at the same time, since only the worm 47 can drive the worm gear 46 to rotate, and the worm gear 46 cannot drive the worm 47 to rotate, it can be avoided that: during forging, the force causing the blank to deform squeezes the inner walls of the two die bodies 42, causing the two die bodies 42 to move away from each other, so that the two die bodies 42 perform an untimely mold opening action, and at the same time, the shape of the forged blank cannot be confirmed.

[0056] In the embodiment of the present invention, a material rack 5 is provided, which has multiple blanks arranged inside it, and is fixedly connected to the frame 1; specifically, a first spring 51 is arranged inside the material rack 5; specifically, the first spring 51 is a compression spring; the end of the first spring 51 abuts against one of the blanks, a blank discharging plate 52 is slidably connected to the material rack 5, and a second spring 53 is arranged between the blank discharging plate 52 and the material rack 5; specifically, the second spring 53 is a tension spring; the blank discharging plate 52 abuts and cooperates with the blank taking ring 67, a connecting rod 54 is rotatably connected to the blank discharging plate 52, one end of the connecting rod 54 is rotatably connected to a limiting rod 55, the limiting rod 55 is rotatably connected to the material rack 5, and one end of the material rack 5 abuts and cooperates with each blank.

[0057] It should be noted that: as Figure 10 shown, the rotation axis of the limiting rod 55 is located at the midpoint position along its own length direction.

[0058] As Figure 9 、 10 shown, a blank discharging through groove is opened at one end inside the material rack 5, so that the blank at the outermost end inside the material rack 5 can move inside the material rack 5 and reach the blank discharging through groove, and due to the self - gravity of the blank, it will fall downward. At this time, the first spring 51 is in the initial state, and the blank discharging plate 52 is located directly below the blank discharging through groove, and can pick up the fallen blank, preparing for putting the blank into the two die bodies 42 next.

[0059] It must be mentioned that the inner cavity height of the material rack 5 is equal to the height of the blank, and the distance between the top of the blank discharging plate 52 and the bottom of the material rack 5 is less than the height of the blank, that is: after the blank at the outermost end inside the material rack 5 falls, the top of the blank is located inside the blank discharging through groove, and the top of the blank is supported by the top of the blank discharging plate 52.

[0060] The driving mechanism 6 has the following functions: First, driving the forging head 3 to reciprocate vertically; Second, driving the turntable 2 to rotate intermittently in one direction; Third, driving the material taking ring 67 to abut and cooperate with the blanking plate 52, so as to drive the blank to pass through the material taking ring 67 and fall between the two die bodies 42.

[0061] Specifically, the driving mechanism 6 includes a rotating shaft 64 rotatably connected to the frame 1, and a material taking ring 67 is fixedly connected to the rotating shaft 64; the driving mechanism 6 further includes a first belt pulley 61 fixedly connected to the screw rod 32, a second belt pulley 62 is fixedly connected to the rotating shaft 64, a belt 63 is arranged between the first belt pulley 61 and the second belt pulley 62, a pawl 65 is elastically arranged on the rotating shaft 64, a ratchet wheel 66 is fixedly connected to the turntable 2, and the pawl 65 is in clamping cooperation with the ratchet wheel 66; wherein, a torsion spring is arranged between the pawl 65 and the rotating shaft 64.

[0062] The process of placing the blank is as follows: the rotating shaft 64 rotates. At this time, due to the one-way transmission effect of the pawl 65 and the ratchet wheel 66, the turntable 2 remains stationary. On the other hand, the rotating shaft 64 drives the screw rod 32 to rotate through the first belt pulley 61, the second belt pulley 62 and the belt 63. At this time, the rotation of the screw rod 32 drives the forging head 3 to move vertically downward, so as to perform forging operations on a set of molds 4 located at the forging station. On the other hand, the rotating shaft 64 drives the material taking ring 67 to rotate synchronously. During the rotation process, the material taking ring 67 gradually approaches and abuts against the blanking plate 52. Due to their abutting effect, the blanking plate 52 slides on the material rack 5, and the second spring 53 undergoes elastic deformation and extends. As the blanking plate 52 slides, a blank located in the blanking through groove will be transferred from the top of the blanking plate 52 to the top of the material taking ring 67, and will fall from the central ring of the material taking ring 67 and land in the two die bodies 42.

[0063] It can be understood that when the blanking plate 52 starts to slide, the blanking plate 52 drives one end of the connecting rod 54 to move synchronously, so that the other end of the connecting rod 54 drives the limiting rod 55 to rotate, so that one end of the limiting rod 55 abuts and limits other blanks, avoiding the mutual abutment between other blanks and a blank located in the blanking through groove under the elastic force of the first spring 51, making it difficult for the blank located in the blanking through groove to fall.

[0064] During the rotation of the turntable 2, it successively has: a forging station, a blanking stroke, a mold closing stroke and a feeding station;

[0065] At the forging station: the two die bodies 42 abut against each other to limit the blank, and the respective support plates 43 abut against each other to support the blank;

[0066] During the blanking stroke: the rotating shaft 64 rotates in the first direction, driving the forging head 3 to move vertically upward and driving the turntable 2 to rotate unidirectionally. First, each support plate 43 slides radially along the positioning ring 41 and moves away from each other, thereby canceling the support for the blank. Secondly, the two die bodies 42 move away from each other to cancel the clamping of the blank, so that the forged blank falls downward from the inside of the positioning ring 41 to complete the blanking action;

[0067] During the mold closing stroke: the turntable 2 continues to rotate, first making each support plate 43 abut against each other, and then making the two die bodies 42 abut against each other;

[0068] At the loading station: the rotating shaft 64 rotates in the second direction, driving the forging head 3 to move vertically downward to forge the blank located at the forging station. At the same time, the blank taking ring 67 moves to the position of the material rack 5, so that the blank closest to the blank taking ring 67 at one end in the material rack 5 passes through the blank taking ring 67 and freely falls, and lands between the two die bodies 42 of another mold 4.

[0069] Only some exemplary embodiments of the present invention are described above by way of illustration. Without doubt, for those of ordinary skill in the art, the described embodiments can be modified in various different ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
