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

At the same time, the picking ring moves to the position of the material rack, so that the blank in the material rack closest to one end of the picking ring passes through the picking ring and falls freely, and falls between the two mold bodies of the other mold.

[0021] 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 described in detail below with reference to the accompanying drawings.

[0022] See also Figure 1-10 The embodiment of the present invention provides an automatic hot forging die for automobile parts, comprising: a frame 1; a turntable 2, which is intermittently rotatably connected to the frame 1; The forging head 3 is vertically slidably connected to the frame 1; specifically, a vertical plate 31 is fixedly connected to the frame 1, and the forging head 3 is slidably connected to the vertical plate 31. A screw rod 32 is rotatably connected to the frame 1, and the screw rod 32 is screwed to the forging head 3. The forging head 3 realizes vertical reciprocating movement on the frame 1 through the reciprocating rotation of the screw rod 32, thereby forging the blank.

[0023] In an embodiment of the present invention: multiple groups of molds 4, the number of molds 4 is four groups; each group 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 abut against each other, and a plurality of support plates 43 are slidably connected to the positioning ring 41, and each support plate 43 abuts against each other.

[0024] It can be understood that the diameter of the blank before forging is relatively small, and a forging space is formed between the positioning ring 41 and the two mold bodies 42 and the support plates 43. Therefore, before forging begins, the blank is located in the positioning ring 41 and supported by the support plates 43. 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 abutment, the inner wall of the mold body 42 coincides with the inner wall of the positioning ring 41.

[0025] Specifically, the two mold bodies 42 are both fixedly connected with a first abutting rod 421, and the turntable 2 is provided with a first sliding groove 21 for the two first abutting rods 421 to slide. Figure 5 As shown, a slider is fixedly connected to the mold body 42, and a first abutment rod 421 is fixedly connected to the slider. By sliding the slider in the first slide groove 21, the mold body 42 will not rotate during the sliding process, thereby avoiding the two mold bodies 42 from being unable to effectively abut; each support plate 43 is fixedly connected to a second abutment rod 431, and a second slide groove 22 is provided on the turntable 2 for each second abutment rod 431 to slide; it can be understood that the first abutment rod 421 and the second abutment rod 431 both penetrate and extend to the outside of the turntable 2.

[0026] More specifically, the mold 4 also includes a rotating plate 44 rotatably connected to the turntable 2, and a through groove is opened on the rotating plate 44 for each second abutment rod 431 to slide and abut. Two guide frames 45 are fixedly connected to the rotating plate 44, and the two first abutment rods 421 slide and abut against the two guide frames 45 respectively.

[0027] The through slot includes an opening slot 441 and an arc-shaped slot 442 , and the opening slot 441 and the arc-shaped slot 442 are connected to each other.

[0028] The guide frame 45 is composed of a delay section 451 and a motion section 452 .

[0029] When the rotating plate 44 rotates, it can drive the guide frame 45 to rotate synchronously. During the rotation, through the cooperation of the opening and closing groove 441, the second abutment rod 431 and the second slide groove 22, each support plate 43 can slide radially along the positioning ring 41 and move away from each other, thereby canceling the support for the blank; during this period, the first abutment rod 421 slides in the delay section 451, so that the two mold bodies 42 remain stationary; the effect brought about by this is: the support for the blank is canceled by each support plate 43, so that the blank is prevented from sticking to the support plate 43. At the same time, as the support plate 43 cancels the support for the blank, it can also prepare for the unloading of the blank, so as to avoid the interference of the support plate 43 with the unloading process.

[0030] Next to the above, as the rotation proceeds, the second abutment rod 431 slides in the arc groove 442, so that the support plates 43 remain in an open state away from each other, and the first abutment rod 421 slides from the delay section 451 into the motion section 452, so that the two first abutment rods 421 move away from each other, so that the two first abutment rods 421 slide in the two first slide grooves 21 respectively, causing the two mold bodies 42 to move away from each other, completing the mold opening action; it can be understood that the positioning ring 41 limits the position of the blank, and the two mold bodies 42 are separated from the blank as they move away from each other, so as to prevent the blank from sticking to the two mold bodies 42; and when the mold opening action is completed, the blank will pass through the positioning ring 41 and fall downward due to its own gravity, completing the material unloading action.

[0031] Specifically, the specific rotation method of the rotating plate 44 is: 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 is meshed 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 is meshed with the first rack 49 and the second rack 410 respectively.

[0032] Through the gear 48 and the first rack 49 and the second rack 410, the worm wheel 46 and the worm 47 can drive the rotating plate 44 to rotate forward and reversely; at the same time, since only the worm 47 can drive the worm wheel 46 to rotate, and the worm wheel 46 cannot drive the worm 47 to rotate, it can be avoided that: during forging, the blank generates a deformation force that squeezes the inner walls of the two mold bodies 42, causing the two mold bodies 42 to move away from each other, thereby causing the two mold bodies 42 to open the mold at an inappropriate time, and at the same time making it impossible to confirm the shape of the blank after forging.

[0033] In an embodiment of the present invention, a material rack 5 is provided with multiple sections of blanks inside, which are fixedly connected to the frame 1; specifically, a first spring 51 is provided 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 blanking plate 52 is slidably connected to the material rack 5, and a second spring 53 is provided between the blanking plate 52 and the material rack 5; specifically, the second spring 53 is a tension spring; the blanking plate 52 abuts against and cooperates with the material picking ring 67, a connecting rod 54 is rotatably connected to the blanking 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 against and cooperates with each blank.

[0034] Need to explain: Fig.10 As shown, the rotation axis of the limiting rod 55 is located at the midpoint along its own length direction.

[0035] like Fig. 9 , 10 As shown, a material unloading groove is provided at one end of the material rack 5, so that a blank at the end of the material rack 5 can reach the material unloading groove as it moves in the material rack 5, and fall downward due to the gravity of the blank. At this time, the first spring 51 is in the initial state, and the material unloading plate 52 is located directly below the material unloading groove, so that the fallen blank can be received, and preparations are made for the subsequent placement of the blank into the two mold bodies 42.

[0036] 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 blanking plate 52 and the bottom of the material rack 5 is smaller than the height of the blank, that is, after a blank at the end of the material rack 5 falls, the top of the blank is located in the blanking channel, and the top of the blank is supported by the top of the blanking plate 52.

[0037] The driving mechanism 6 has the following functions: 1. driving the forging head 3 to reciprocate vertically; 2. driving the turntable 2 to intermittently rotate unidirectionally; 3. driving the picking ring 67 to abut against the unloading plate 52, so that the blank can pass through the picking ring 67 and fall between the two mold bodies 42.

[0038] Specifically, the driving mechanism 6 includes a rotating shaft 64 rotatably connected to the frame 1, and a material picking ring 67 is fixedly connected to the rotating shaft 64; the driving mechanism 6 also includes a first pulley 61 fixedly connected to the screw 32, a second pulley 62 is fixedly connected to the rotating shaft 64, a belt 63 is arranged between the first pulley 61 and the second pulley 62, a pawl 65 is elastically arranged on the rotating shaft 64, a ratchet 66 is fixedly connected to the turntable 2, and the pawl 65 is snap-fitted with the ratchet 66; wherein a torsion spring is arranged between the pawl 65 and the rotating shaft 64.

[0039] The process of feeding the blank is as follows: the rotating shaft 64 rotates, at this time, the turntable 2 remains stationary through the one-way transmission effect of the pawl 65 and the ratchet 66, and on the other hand, the rotating shaft 64 drives the screw 32 to rotate through the first pulley 61, the second pulley 62, and the belt 63. At this time, the rotation of the screw 32 drives the forging head 3 to move vertically downward, thereby performing a forging operation on a group of molds 4 located at the forging station, and on the other hand, the rotating shaft 64 drives the feeding ring 67 to rotate synchronously. During the rotation process, the feeding ring 67 gradually approaches and abuts against the lower material plate 52. Due to the abutment between the two, 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 slot will be transferred from the top of the blanking plate 52 to the top of the feeding ring 67, and fall from the center ring of the feeding ring 67 and fall into the two mold bodies 42.

[0040] It can be understood that when the unloading plate 52 starts to slide, the unloading 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 the other blanks, avoiding the mutual abutment between the other blanks and a blank located in the unloading slot under the elastic force of the first spring 51, making it difficult for the blank located in the unloading slot to fall.

[0041] During the rotation process, the turntable 2 has: a forging station, a material unloading stroke, a mold closing stroke and a material loading station in sequence; At the forging station: the two mold bodies 42 abut against each other to limit the blank, and the support plates 43 abut against each other to support the blank; In 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, firstly making each support plate 43 slide along the radial direction of the positioning ring 41 and move away from each other, thereby canceling the support for the blank, and secondly making the two mold bodies 42 move away from each other to cancel the clamping of the blank, so that the blank after forging falls downward from the inside of the positioning ring 41, completing the blanking action; Mold closing stroke: the turntable 2 continues to rotate, firstly making the support plates 43 abut against each other, and then making the two mold bodies 42 abut against each other; At the loading station: the rotating shaft 64 rotates along 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 picking ring 67 moves to the position of the material rack 5, so that the blank at one end of the material rack 5 closest to the picking ring 67 passes through the picking ring 67 and falls freely, and falls between the two mold bodies 42 of the other mold 4.

[0042] The above description is only by way of illustration of certain exemplary embodiments of the present invention. It is undoubted that those skilled in the art can modify the described embodiments in various 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.
