Description

Technical Field

[0001] This invention specifically relates to the field of automotive parts forging technology, and more particularly to a forging process for automotive steering arms. Background Technology

[0002] The steering arm is a component of the steering system in an automobile, transmitting the movement of the steering wheel to the tie rod or drag link. Steering arms are typically manufactured using forging. Forging is a processing method that uses hammering or pressing to shape and size metal at high or room temperature, thereby altering its physical properties.

[0003] A steering arm forging die is provided, comprising an upper module with a punch at the bottom and a lower module with a die at the top. The punch and die form a cavity for forging the steering arm. The cavity includes a bending cavity and a forming cavity arranged in parallel. During forging, the bar stock is first placed into the bending cavity, and the upper module is lowered to close the die, causing the bar stock to bend and deform. Then, the upper module is lifted, and the bent bar stock is moved to the forming cavity. The upper module is lowered again to close the die, and the bent bar stock flows in the forming cavity and fills the forming cavity, thus producing the steering arm.

[0004] In the above solution, the bar stock is pressed into the forming cavity to close the upper and lower modules and form the steering arm. In the existing bar stock processing, a certain gap needs to be left between the upper and lower dies so that the excess bar stock can be pressed outward. However, when the allowance left before bar stock processing is small, the bar stock is pressed out of the die under the action of the pressing force, which makes it difficult for the edges and corners of the bar stock inside the die to fit effectively with the die. In the existing process, a larger allowance is generally left before processing so that when the bar stock is discharged from the die, the edges and corners of the bar stock inside the die can still fit with the die. This method causes material waste, and after forming, due to the large amount of bar stock remaining around the steering arm, the subsequent surface treatment process is time-consuming and labor-intensive. Summary of the Invention

[0005] The purpose of this invention is to address the shortcomings of existing technologies by providing a forging process for automotive steering arms. This process solves the problems of material waste caused by leaving a large allowance in the bar stock before processing, and the time-consuming and labor-intensive subsequent surface treatment process due to the large amount of remaining bar stock around the steering arm after forming.

[0006] This invention is implemented as follows: a forging process for an automotive steering arm, comprising the following steps;

[0007] Step S1: Heat the billet at a high temperature, and then preliminarily shape the heated billet in the mold;

[0008] Step S2: Place the pre-formed material into the forming groove of the forming mold, and then cover it with another identical forming mold. Each forming mold has a retaining ring circumferentially arranged along the outer side of the forming groove. The retaining rings are slidably connected to the forming mold, and the retaining rings on the two forming molds can slide together. Several transmission rods are distributed at the corners of the forming groove. Several L-shaped stops are rotatably connected to the back of the forming groove. All L-shaped stops abut against the retaining rings. A thrust mechanism is provided between each L-shaped stop and the transmission rod, which can push the L-shaped stop away from the retaining ring. Each forming mold is equipped with an elastic component, which applies a thrust to the retaining ring in the opposite direction to the L-shaped stop.

[0009] When the two molding dies are closed, the retaining rings on the two molding dies are slidably connected to each other, and a buffer assembly is provided between the two molding dies. When the molding die on one side is pressed down by the pressure mechanism, the two molding dies move closer to each other. Under the action of the retaining ring, the processing material adheres to the molding groove. At this time, the transmission rods are subjected to force one by one. The transmission rods push the L-shaped stops through the thrust mechanism. All the L-shaped stops separate from the retaining ring one by one. When the processing material in the molding die is completely adhered to the edge and corner of the molding die, all the L-shaped stops release the seal on the molding groove. At this time, under the pressure of the pressure mechanism, the processing material is pressed out along the gap between the two molding dies.

[0010] Step S3: After the material is formed, the forming mold is connected to a reset mechanism. The reset mechanism can push all L-shaped stops. The L-shaped stops push the transmission rod into the forming groove through the thrust mechanism to reduce the bonding force between the material and the forming groove, and then separate the forming groove from the material.

[0011] Step S4: Trim, straighten, shot blast, and normalize the shaped material.

[0012] In a further technical solution, the thrust mechanism includes a sleeve, a first piston, a second piston, and a connecting rod;

[0013] The sleeve is fixedly connected to the forming mold. A first piston and a second piston are slidably and sealedly connected in the sleeve. One end of the transmission rod is fixedly connected to the first piston, one end of the connecting rod is fixedly connected to the second piston, and the other end of the connecting rod is connected to the sliding seat.

[0014] In a further technical solution, a first spring is connected between the end face of the sleeve and the first piston.

[0015] In a further technical solution, a sliding seat is slidably connected to the L-shaped stop, and one end of the connecting rod is rotatably connected to the sliding seat.

[0016] In a further technical solution, the elastic component includes a second spring, a spring baffle, and a threaded rod; a limiting seat is fixedly connected to the bottom of the molding die, the threaded rod is threadedly connected to the limiting seat, a connecting seat is fixedly connected to the retaining ring, the threaded rod passes through the connecting seat, the spring baffle is fixedly connected to one end of the threaded rod, and the second spring is disposed between the spring baffle and the limiting seat.

[0017] In a further technical solution, in step S2, the buffer assembly includes a guide rod and a third spring. The guide rod is fixedly connected to one molding die and slidably connected to another molding die. The third spring is sleeved on the outside of the guide rod. When the pressure mechanism presses down, the third spring buffers the extrusion force between the two molding dies.

[0018] In a further technical solution, the reset mechanism includes a push plate, a rotating rod, and a guide block;

[0019] The push plate and the retaining ring have the same shape, and the push plate and the retaining ring are respectively arranged on both sides of all L-shaped retaining seats. The rotating rod is rotatably connected to the forming mold, and the rotating rod is threadedly connected to the push plate. The guide block is fixedly connected to the forming mold, and the guide block is slidably connected to the push plate.

[0020] In a further technical solution, the molding die is rotatably connected to a drive rod, and a bevel gear transmission pair is provided between the drive rod and the rotating rod; in step S3, the drive rod is rotated, and the drive rod drives the push plate to move through the rotating rod. The push plate pushes all the L-shaped stops to rotate and reset. The L-shaped stops push the transmission rod to move into the molding groove through the thrust mechanism, reducing the bonding force between the processed material and the molding groove, and then separating the molding groove from the processed material.

[0021] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0022] The present invention provides a forging process for automotive steering arms, in which a pressure mechanism presses down on one side of the forming mold, and the two forming molds approach each other. Under the action of the retaining ring, the workpiece is fully attached to the edge and corner of the forming groove, thereby improving the forming accuracy of the workpiece.

[0023] This invention provides a forging process for automotive steering arms. Through the cooperation of multiple transmission rods, a thrust mechanism, and an L-shaped stop, it can ensure that all parts of the workpiece are completely fitted with the edges and corners of the forming groove, increasing the processing accuracy of the workpiece. Then, the stop ring quickly releases the seal on the forming groove, allowing the excess workpiece to extend to the gap between the two forming dies. This avoids the forming dies from being deformed by long-term pressure, which would affect the processing accuracy of the forming dies. At the same time, it allows the excess material to be sufficiently extended under the extrusion pressure, thus facilitating subsequent grinding and cutting of the workpiece.

[0024] The present invention provides a forging process for automotive steering arms. After the material is formed, the L-shaped stop pushes the transmission rod into the forming groove through the thrust mechanism, reducing the bonding force between the material and the forming groove. This facilitates the separation of the forming groove from the material and also prevents broken material from clogging the telescopic hole where the transmission rod is located, thus avoiding inconvenience in the subsequent use of the mold.

[0034] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0035] The specific implementation of the present invention will be described in detail below with reference to specific embodiments.

[0036] like Figures 1-8 The image shows a forging process for an automotive steering arm provided by the present invention, comprising the following steps;

[0037] Step S1: Heat the billet at a high temperature, and then preliminarily shape the heated billet in the mold;

[0038] Step S2: Place the pre-formed material into the forming groove 2 of the forming mold 1, and then cover it with another identical forming mold 1. Each forming mold 1 has a retaining ring 3 arranged in a ring around the outside of the forming groove 2. The retaining ring 3 is slidably connected to the forming mold 1, and the retaining rings 3 on the two forming molds 1 can slide to each other. Several transmission rods 4 are distributed at the corners of the forming groove 2. Several L-shaped stops 5 are rotatably connected to the back of the forming groove 2. All L-shaped stops 5 abut against the retaining ring 3. A thrust mechanism 6 is provided between each L-shaped stop 5 and the transmission rod 4. The thrust mechanism 6 can push the L-shaped stop 5 to separate from the retaining ring 3. Each forming mold 1 is provided with an elastic component 7. The elastic component 7 is used to apply a thrust to the retaining ring 3 in the opposite direction to the L-shaped stop 5.

[0039] When the two molding dies 1 are closed, the retaining rings 3 on the two molding dies 1 are slidably connected to each other, and a buffer assembly 8 is provided between the two molding dies 1. When the pressure mechanism presses down on one side of the molding die 1, the two molding dies 1 move closer to each other. Under the action of the retaining ring 3, the processing material adheres to the molding groove 2. At this time, the transmission rod 4 is subjected to force one by one. The transmission rod 4 pushes the L-shaped stop 5 through the thrust mechanism 6. All the L-shaped stop 5 separate from the retaining ring 3 one by one. When the processing material in the molding groove 2 is completely adhered to the corner of the molding groove 2, all the L-shaped stop 5 release the seal on the molding groove 2. At this time, under the pressure of the pressure mechanism, the processing material is pressed out along the gap between the two molding dies 1.

[0040] Step S3: After the material is formed, the forming mold 1 is connected to a reset mechanism 9. The reset mechanism 9 can push all L-shaped stops 5. The L-shaped stops 5 push the transmission rod 4 into the forming groove 2 through the thrust mechanism 6 to reduce the bonding force between the material and the forming groove 2, and then separate the forming groove 2 from the material.

[0041] Step S4: Trim, straighten, shot blast, and normalize the shaped material.

[0042] In embodiments of the present invention, such as Figure 8 As shown, in a preferred embodiment of the present invention, in step S2, the thrust mechanism 6 includes a sleeve 61, a first piston 62, a second piston 63, and a connecting rod 64.

[0043] The sleeve 61 is fixedly connected to the forming mold 1. A first piston 62 and a second piston 63 are slidably and sealingly connected in the sleeve 61. One end of the transmission rod 4 is fixedly connected to the first piston 62, one end of the connecting rod 64 is fixedly connected to the second piston 63, and the other end of the connecting rod 64 is connected to the sliding seat 10.

[0044] In this scheme, the processed material adheres to the corners of the forming groove 2. When the transmission rod 4 is under force, it drives the first piston 62 to slide in the sleeve 61. The first piston 62 moves down, and at this time, under the action of air pressure, the second piston 63 pushes the connecting rod 64 to extend. The connecting rod 64 pushes the L-shaped stop 5 to rotate, thereby releasing the L-shaped stop 5 from limiting the retaining ring 3. Through the cooperation of multiple transmission rods 4, thrust mechanism 6 and L-shaped stop 5, it can be ensured that all parts of the processed material are completely adhered to the corners of the forming groove 2, increasing the processing accuracy of the processed material. Afterwards, the retaining ring 3 quickly releases the seal on the forming groove 2, thereby allowing the excess processed material to extend to the gap between the two forming molds 1, avoiding the long-term deformation of the forming mold 1 under pressure, which would affect the processing accuracy of the forming mold 1. At the same time, it can allow the excess material to extend sufficiently under the action of extrusion pressure, thus facilitating the subsequent grinding and cutting of the processed material.

[0045] In embodiments of the present invention, such as Figure 8 As shown, in a preferred embodiment of the present invention, a first spring 65 is connected between the end face of the sleeve 61 and the first piston 62; the first spring 65 provides elastic support for the first piston 62.

[0046] In embodiments of the present invention, such as Figure 3 As shown, in a preferred embodiment of the present invention, a sliding seat 10 is slidably connected to the L-shaped stop 5, and one end of the connecting rod 64 is rotatably connected to the sliding seat 10; when the connecting rod 64 extends, the connecting rod 64 pushes the sliding seat 10, and the sliding seat 10 slides in the L-shaped stop 5. At this time, under the push of the connecting rod 64, the L-shaped stop 5 rotates to release the restriction on the retaining ring 3.

[0047] In embodiments of the present invention, such as Figure 6 As shown, in a preferred embodiment of the present invention, the elastic component 7 includes a second spring 71, a spring baffle 72, and a threaded rod 73;

[0048] The bottom of the molding mold 1 is fixedly connected to a limiting seat 11, the threaded rod 73 is threadedly connected to the limiting seat 11, the retaining ring 3 is fixedly connected to a connecting seat 12, the threaded rod 73 passes through the connecting seat 12, the spring baffle 72 is fixedly connected to one end of the threaded rod 73, and the second spring 71 is disposed between the spring baffle 72 and the limiting seat 11.

[0049] After the L-shaped stop 5 rotates to release the restriction on the retaining ring 3, the second spring 71 pushes the retaining ring 3 to move in the opposite direction, thereby causing the retaining ring 3 to retract into the forming mold 1; rotate the threaded rod 73, and the threaded rod 73 moves back and forth relative to the limiting seat 11. The threaded rod 73 drives the spring baffle 72 to move synchronously, and the spring baffle 72 drives the second spring 71 to move back and forth, thereby adjusting the supporting force of the second spring 71 on the retaining ring 3.

[0050] In embodiments of the present invention, such as Figure 4 As shown, in a preferred embodiment of the present invention, the buffer assembly 8 includes a guide rod 81 and a third spring 82. The guide rod 81 is fixedly connected to one molding die 1 and slidably connected to another molding die 1. The third spring 82 is sleeved on the outside of the guide rod 81. When the pressure mechanism presses down, the third spring 82 buffers the extrusion force between the two molding dies 1.

[0051] In embodiments of the present invention, such as Figure 5 As shown, in a preferred embodiment of the present invention, the reset mechanism 9 includes a push plate 91, a rotating rod 92, and a guide block 93; the push plate 91 has the same shape as the retaining ring 3, and the push plate 91 and the retaining ring 3 are respectively disposed on both sides of all L-shaped retaining seats 5; the rotating rod 92 is rotatably connected to the molding mold 1, and the rotating rod 92 is threadedly connected to the push plate 91; the guide block 93 is fixedly connected to the molding mold 1, and the guide block 93 is slidably connected to the push plate 91; the molding mold 1 is rotatably connected to a drive rod 13, and a bevel gear transmission pair 14 is disposed between the drive rod 13 and the rotating rod 92;

[0052] Under the pressure of extrusion, the material pushes the transmission rod 4 to retract to the lower part of the forming groove 2. At this time, although the material can fully fit with the corner of the forming groove 2, some of the material is easy to get stuck in the telescopic hole where the transmission rod 4 is located. When the finished material is taken out, the material stuck in the telescopic hole adheres to the hole wall, increasing the difficulty of separating the material from the forming mold 1. At the same time, when taking out the material, some of the material is easy to break and block into the telescopic hole. After the temperature of this broken material drops, it adheres to the hole wall and is difficult to take out, causing inconvenience to the subsequent use of the mold 1.

[0053] In step S3, the drive rod 13 is rotated, and the drive rod 13 drives the rotating rod 92 to rotate through the bevel gear transmission pair 14. The rotating rod 92 drives the push plate 91 to move through the threaded transmission. The push plate 91 pushes all the L-shaped stops 5 to rotate and reset. The L-shaped stops 5 push the transmission rod 4 into the forming groove 2 through the thrust mechanism 6, reducing the bonding force between the processed material and the forming groove 2. This makes it easier to separate the forming groove 2 from the processed material. At the same time, it prevents the broken processed material from blocking the telescopic hole where the transmission rod 4 is located, which would cause inconvenience to the subsequent use of the mold 1.

[0054] In conjunction with the above embodiments: a forging process for an automotive steering arm includes the following steps;

[0055] Step S1: Heat the billet at a high temperature, and then preliminarily shape the heated billet in the mold;

[0056] Step S2: Place the pre-formed material into the forming groove 2 of the forming mold 1. Then, cover it with another identical forming mold 1. When the two forming molds 1 are closed, the pressure mechanism presses down on one side of the forming mold 1, and the two forming molds 1 move closer to each other. Under the action of the retaining ring 3, the material is completely adhered to the edges and corners of the forming groove 2, improving the forming accuracy of the material. At this time, the transmission rods 4 are subjected to force one by one. The transmission rods 4 drive the first piston 62 to slide in the sleeve 61. The first piston 62 moves down. At this time, under the action of air pressure, the second piston 63 pushes the connecting rod 64 to extend. The connecting rod 64 pushes the L-shaped stop. 5. Rotation releases the L-shaped stop 5 from limiting the retaining ring 3, causing the retaining ring 3 to retract into the forming mold 1. Through the cooperation of multiple transmission rods 4, thrust mechanism 6 and L-shaped stop 5, it can be ensured that all parts of the processed material are completely in contact with the edges and corners of the forming groove 2, increasing the processing accuracy of the processed material. Then, the retaining ring 3 quickly releases the seal on the forming groove 2, allowing the excess processed material to extend into the gap between the two forming molds 1, avoiding long-term deformation of the forming mold 1 and affecting the processing accuracy of the forming mold 1. At the same time, it can allow the excess material to extend sufficiently under the extrusion pressure, thus facilitating subsequent grinding and cutting of the processed material.

[0057] Step S3: After the material is formed, rotate the drive rod 13. The drive rod 13 drives the rotating rod 92 to rotate through the bevel gear transmission pair 14. The rotating rod 92 drives the push plate 91 to move through the thread transmission. The push plate 91 pushes all the L-shaped stops 5 to rotate and reset. The L-shaped stops 5 push the transmission rod 4 to move into the forming groove 2 through the thrust mechanism 6, reducing the bonding force between the material and the forming groove 2. This makes it easier to separate the forming groove 2 from the material. At the same time, it prevents the broken material from blocking the telescopic hole where the transmission rod 4 is located, which would cause inconvenience to the subsequent use of the mold 1.

[0058] Step S4: Trim, straighten, shot blast, and normalize the shaped material.

Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
