Description

Technical Field

[0001] The invention relates to the technical field of automobile connecting rod processing, and in particular to a forging device and a processing technology for automobile connecting rod processing. Background Art

[0002] As a key transmission component of the engine, the forging process of the automobile connecting rod directly affects its mechanical properties and service life. In modern forging production, in order to improve forging accuracy and efficiency, multi-station forging equipment is often used, that is, the same equipment is equipped with a shaping forging chamber, a shaping forging chamber and a forming forging chamber in sequence, and by gradually applying different forging forces, the connecting rod can be precisely formed from the blank to the final shape.

[0003] In the forging process, after the blank is initially forged in the shaping forging chamber, it needs to be transferred to the shaping forging chamber by a robot for further plastic deformation. However, in the process of the robot transferring the blank, there are the following technical problems: 1. In the process of the robot clamping the blank and conveying it to the shaping forging chamber, since the shape of the forging blank has not yet been completely stabilized, its thermal expansion, center of gravity change and uneven clamping force of the robot may cause the blank to shift or tilt during the conveying process, affecting the subsequent forging accuracy.

[0004] 2. If the blank is offset during the transfer process, it may not be able to accurately dock with the shaping forging die when entering the shaping forging chamber, resulting in uneven force on the blank, which in turn affects the metal flow direction, leading to forging defects (such as inclusions, underfilling, eccentricity, etc.), and reducing the forming quality of the connecting rod.

[0005] 3. Existing manipulators usually clamp the blanks with fixed jaws or vacuum adsorption. However, in a high temperature environment, the fixed jaws may cause the clamping force to change due to thermal expansion, while the vacuum adsorption method may affect the adsorption force due to the irregular surface of the blank or the oxide layer, which may cause the blank to shake or slip during the transportation process, reducing the forging stability. Summary of the invention

[0006] In view of the above problems, a forging equipment for processing automobile connecting rods is provided. By proposing a forging equipment that can not only automatically correct the forging position of the connecting rod when forging the connecting rod, it solves the technical problems of existing multi-station forging equipment, which is prone to limited blank positioning accuracy and inaccurate docking between the blank and the shaping forging die during the forging and transportation of the connecting rod, thereby affecting the forming quality.

[0007] To solve the problems of the existing technology, the present invention provides a forging device for processing automobile connecting rods, including: a base frame; a forging module composed of a lower die set and an upper die set; a forming module horizontally arranged on the lower die set; the forming module is provided with a forging table capable of supporting a blank, and the forging table is provided with a first forging cavity, a second forging cavity and a third forging cavity capable of successively forging the blank; a correction module, there are two groups of correction modules, the two groups of correction modules are oppositely arranged on the lower die set, and the correction ends of the two groups of correction modules are respectively arranged towards both ends of the second forging cavity; the correction module is provided with a correction part capable of correcting the blank in the second forging cavity and a driving unit capable of controlling the correction part to approach the blank in the non-forging state and move away from the blank in the forging state.

[0008] Preferably, the correction module further includes a limiting frame, a sliding rod capable of driving the correction part to horizontally approach or move away from the second forging cavity, and a reset unit capable of driving the sliding rod to elastically retract; the sliding rod is horizontally slidably arranged on the top of the limiting frame; the correction part is detachably arranged at the front end of the sliding rod; the reset unit is coaxially sleeved and installed at the end of the sliding rod, and one end of the reset unit abuts against the limiting frame, and the other end of the reset unit is fixedly connected to the sliding rod.

[0009] Preferably, the reset unit includes a spring, a limiting part and a conduction wheel; the limiting part is centrally and fixedly arranged outside the sliding rod and close to the end of the sliding rod; the spring is coaxially sleeved outside the sliding rod; one end of the spring abuts against the limiting part, and the other end of the spring abuts against the limiting part; there are two conduction wheels, and the two conduction wheels are relatively rotatably arranged on both sides of the limiting part.

[0010] Preferably, an adjustable frame capable of longitudinally adjusting is also slidably arranged at the front end of the sliding rod; the correction part is detachably arranged on the adjustable frame.

[0011] Preferably, the correction part is composed of a V-shaped frame and a connecting frame fixedly arranged on one side of the V-shaped frame.

[0012] Preferably, the driving unit is provided with a driving rod and a linkage conduction unit capable of controlling the synchronous driving of the driving rod when the upper die set is lifted.

[0013] Preferably, the linkage conduction unit includes a second hinge part, a sleeve and an adjusting rod slidably arranged in the sleeve; the front end of the sleeve is hinged to the side wall of the upper die set through the second hinge part; the adjusting rod is slidably arranged in the sleeve and the front end is hinged to the driving rod and forms an acute angle with the driving rod.

[0014] Preferably, the linkage conduction unit further includes a locking member capable of adjusting the telescopic position of the adjusting rod, and the locking member is detachably arranged outside the sleeve.

[0015] A processing technology of a forging device for processing automobile connecting rods, which is applied to a forging device for processing automobile connecting rods, includes the following steps: S1: Use a manipulator to send the heated blank into the first forging cavity, and then drive the upper die set to move downward to cooperate with the lower die set to perform preliminary forging on the blank, so that the blank forms a connecting rod blank with a preliminary shape and round handles with different diameters at both ends; S2: The upper die set resets, and the manipulator grabs the preliminarily formed blank and transfers it to the second forging cavity; the upper die set is lifted in two stages when lifting: the first stage of lifting: the manipulator completes the transfer of the blank to the second forging cavity to avoid interference between the correction part and the manipulator; the second stage of lifting: the manipulator completely withdraws, and the upper die set synchronously drives the correction module to act during the lifting process; S3: When the correction module is working, it first drives the driving unit to act. The driving unit synchronously conducts the pressure to the reset unit during the process of being pulled up by the upper die set, and then applies a thrust to the sliding rod through the reset unit. Finally, the correction part is pushed towards the second forging cavity through the sliding rod, so as to achieve the effect of correcting the blank by using the correction part; place the blank in the second forging cavity in the correct posture; S4: The upper die set presses down to perform secondary forging on the blank, so that it gradually forms the target shape; the upper die set resets, and the manipulator transfers the blank to the third forging cavity; finally, the forging is completed.

[0016] The beneficial effects of the present invention compared with the prior art are: 1. Through the correction module of the present invention, the effect of automatically correcting both ends of the blank when the manipulator transfers the blank to the second forging cavity is realized, effectively avoiding problems such as axial offset and inclination of the blank caused by the change of the center of gravity, clamping error or vibration during the transfer process, and improving the centering accuracy of the blank during the forging process.

[0017] 2. Through the two-stage lifting of the upper die set of the present invention, in the first stage of lifting, the manipulator can complete the transfer of the blank, and in the second stage of lifting, the correction module is started, so that the correction part is accurately pushed to the end of the blank for correction. Effectively avoiding the movement interference between the correction part and the manipulator, ensuring the accurate matching of the correction action and the forging process, thereby improving the overall forging accuracy.

[0018] 3. Through the linkage conduction unit of the present invention, the effect of flexibly adjusting the pushing stroke of the correction part according to blanks of different specifications is realized, ensuring that the correction part can self-adjust according to the required correction parameters, so that the correction part is always located at the optimal correction position.

[0030] To further understand the features, technical means, specific purposes and functions achieved by the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0031] See Figures 1 to 10 As shown: A forging device for processing automotive connecting rods includes: a base frame 1; a forging module 2, which consists of a lower die set 22 and an upper die set 21; a forming module 3, which is horizontally arranged on the lower die set 22; the forming module 3 is provided with a forging table 31 capable of carrying a blank, and the forging table 31 is provided with a first forging cavity 32, a second forging cavity 33 and a third forging cavity 34 capable of successively forging the blank; a correction module 4, there are two groups of the correction module 4, the two groups of correction module 4 are oppositely arranged on the lower die set 22, and the correction ends of the two groups of correction module 4 are respectively arranged towards both ends of the second forging cavity 33; the correction module 4 is provided with a correction part 44 capable of correcting the blank in the second forging cavity 33 and a driving unit 45 capable of controlling the correction part 44 to approach the blank in the non-forging state and move away from the blank in the forging state.

[0032] When it is necessary to forge the heated blank, first, the blank is accurately placed on the forming module 3 by a manipulator and transported into the first forging cavity 32 for preliminary forging. In the first forging cavity 32, the blank is deformed by force to form a preliminary plastic structure with round handles of different diameters at both ends, ensuring that the blank has the basic shape for subsequent processing.

[0033] When the preliminary forging is completed, the manipulator is activated to transfer the shaped blank from the first forging cavity 32 to the second forging cavity 33 for further precision plastic deformation. However, in order to prevent the blank from shifting, tilting or axis deviation during the transfer process, which may affect the subsequent forging accuracy, when the blank enters the second forging cavity 33, the two groups of correction module 4 will act synchronously with the lifting of the upper die set, and the driving unit 45 is used to drive the correction part 44 to approach and accurately position both ends of the blank along the horizontal direction. Thus, the blank entering the second forging cavity 33 can be centered in the second forging cavity 33 at the correct position; this process ensures that the blank can strictly maintain axial alignment and avoid affecting the subsequent plastic deformation accuracy due to position errors.

[0034] Through the design of manipulator transfer, synchronous adjustment of the correction module 4 and two-way positioning of the correction part 44, the problems of axial deviation, misalignment or tilting of the blank during the transfer process can be effectively solved, ensuring the position accuracy of the blank when it enters the second forging cavity 33 and improving the forming consistency of subsequent forging. Compared with the traditional transfer scheme that relies on a single clamping method, the present invention can dynamically correct the position of the blank, ensuring that the blank is always in a precisely stressed state during the multi-station forging process, thereby improving the forging accuracy, reducing the rejection rate, and enhancing the stability and automation level of forging production.

[0035] See Figures 8 to 10 As shown: The calibration module 4 further includes a limit frame 41, a sliding rod 42 capable of driving the calibration part 44 to horizontally approach or move away from the second forging cavity 33, and a reset unit 43 capable of driving the sliding rod 42 to elastically retract; the sliding rod 42 is horizontally slidably arranged on the top of the limit frame 41; the calibration part 44 is detachably arranged at the front end of the sliding rod 42; the reset unit 43 is coaxially sleeved and installed at the end of the sliding rod 42, and one end of the reset unit 43 abuts against the limit frame 41, and the other end of the reset unit 43 is fixedly connected to the sliding rod 42.

[0036] The limit frame 41 is vertically arranged on the lower die set 22 and is arranged at the end close to the second forging cavity 33.

[0037] When it is necessary to calibrate the end of the blank located in the second forging cavity 33, first drive the drive unit 45 to start, so that the drive unit 45 applies pressure to the end of the reset unit 43. Under this action, the reset unit 43 is stressed and contracts axially, and synchronously drives the sliding rod 42 to horizontally slide along the top of the limit frame 41 during the contraction process, so that the sliding rod 42 gradually moves towards the second forging cavity 33. When the sliding rod 42 reaches the preset calibration position, the calibration part 44 immediately applies a calibration action to the end of the blank to ensure that the blank is axially aligned during the forging process and prevent the plastic deformation effect from being affected by the end offset; similarly, when the drive unit 45 removes the external force, the sliding rod 42 will be driven by the reset unit 43 to reset to the initial position synchronously.

[0038] Through the cooperation of the drive unit 45, the reset unit 43, the sliding rod 42 and the calibration part 44, it realizes how to automatically calibrate the blank, effectively avoiding the forming errors caused by the end offset and uneven force of the blank during the traditional forging process. Compared with the traditional method that relies on manual adjustment or a single limit mechanism, the calibration mechanism of the present invention can dynamically adapt to the size and shape changes of different blanks, ensure the accurate alignment of the blank when entering the subsequent plastic forging stage, thereby improving the forging accuracy and reducing the material loss.

[0039] See Figure 10 As shown: The reset unit 43 includes a spring 431, a limit part 432 and a conduction wheel 433; the limit part 432 is centrally and fixedly arranged outside the sliding rod 42 and is arranged close to the end of the sliding rod 42; the spring 431 is coaxially sleeved outside the sliding rod 42; one end of the spring 431 abuts against the limit part 432, and the other end of the spring 431 abuts against the limit part 432; there are two conduction wheels 433, and the two conduction wheels 433 are relatively rotatably arranged on both sides of the limit part 432.

[0040] Since the limiting part 432 is fixedly connected to the sliding rod 42, when the limiting part 432 is pressed by the driving unit 45, so that the sliding rod 42 slides horizontally towards the second forging cavity 33, at this time, the driving end of the driving unit 45 first contacts the two conduction wheels 433, so as to conduct the driving force without causing hard friction on the contact surface. At this time, the driving force is then conducted to the limiting part 432 through the two conduction wheels 433, so as to synchronously drive the sliding rod 42 to slide towards the second forging cavity 33 by using the limiting part 432, thereby realizing the effect of correcting the blank by using the correcting part 44 detachably arranged at the front end of the sliding rod 42; after the blank is corrected by the correcting part 44, when the driving unit 45 removes the driving force, at this time, the limiting part 432 will be pushed away from the sliding rod 42 again under the action of the spring 431 in the compressed state, thus realizing the effect of driving the sliding rod 42 and the correcting part 44 to reset.

[0041] See Figure 10 As shown: A longitudinally adjustable adjusting frame 421 is also slidably arranged at the front end of the sliding rod 42; the correcting part 44 is detachably arranged on the adjusting frame 421.

[0042] By means of the longitudinally adjustable adjusting frame 421 arranged at the front end of the sliding rod 42, the longitudinal position of the correcting part 44 can be freely adjusted. The adjusting frame 421 can independently adjust the height of the correcting part 44 according to different correction points of different blanks, so as to ensure accurate correction of blanks with different sizes and shapes. This adjustment system makes the correction process more flexible and adaptable, and can cope with the problems of uneven force or size change of different blanks during forging.

[0043] Specifically, the longitudinal adjustment function of the adjusting frame 421 can be adjusted manually by machinery or electrically driven. According to the preset accurate value, the correcting part 44 is adjusted to the best position, so as to ensure the axial positioning accuracy of the blank. The independent design of the adjusting frame 421 ensures that it can quickly adapt to the change of different blank sizes under different working conditions, without complex tools or manual operations, greatly improving the production efficiency and working accuracy.

[0044] See Figure 9 and Figure 10 As shown: The correcting part 44 is composed of a V-shaped frame 441 and a connecting frame fixedly arranged on one side of the V-shaped frame 441.

[0045] The V-shaped frame 441 is detachably connected to the front end of the sliding rod 42 through a connecting frame fixedly arranged on one side, ensuring that it can be quickly replaced or adjusted under different working conditions. The connecting frame is fixedly arranged at the non-opening end of the V-shaped frame 441; when the V-shaped frame 441 corrects the end of the blank, it can automatically achieve precise centering of the blank by using its V-shaped structure, ensuring that the end is in a standard centered state when entering the plastic forming or forging stage, and avoiding affecting the forging accuracy due to offset.

[0046] In addition, the adaptive adjustment characteristic of the V-shaped frame 441 enables it to form a dynamic limiting effect inside the V shape according to the diameter change of the end of the blank. That is, when the blank is placed in the V-shaped frame 441, it can automatically adjust the contact angle according to the ends of different diameters, ensuring that the blank is always located at the optimal center position and avoiding the deviation problem caused by the dimensional tolerance of the end.

[0047] See Figure 4 and Figure 7 As shown: The driving unit 45 is provided with a driving rod 451 and a linkage conduction unit 452 that can control the synchronous driving of the driving rod 451 when the upper die set 21 is lifted.

[0048] The rear end of the driving rod 451 is hinged to the limiting frame 41 through a first hinge portion 4511, the front end of the driving rod 451 is hinged to the rear end of the linkage conduction unit 452; the front end of the linkage conduction unit 452 is hinged to the side wall of the upper die set 21; an acute angle is formed between the linkage conduction unit 452 and the control rod; the side wall of the driving rod 451 abuts against the conduction wheel 433.

[0049] When the upper die set 21 is lifted, that is, when it moves away from the lower die set 22, at this time, the linkage conduction unit 452 hinged to the side wall of the upper die set 21 will be lifted synchronously, and will synchronously drive the driving rod 451 to act during the lifting process; thus, when the upper die set 21 moves away from the lower die set 22, the correcting portion 44 can move horizontally towards the second forging cavity 33, thereby realizing the correction work of the blank; the upper die set 21 is divided into two sections for lifting in the lifted state; when the upper die set 21 performs the first stage of lifting, this is the transfer stage of the blank by the manipulator, when the upper die set 21 performs the second stage of lifting, the transfer manipulator withdraws, and this is the correction stage of the correction module 4, and the correcting portion 44 officially moves towards the second forging cavity 33 direction, thereby realizing the correction of the blank. By dividing the upper die set 21 into two sections for lifting, it can effectively avoid the correcting portion 44 directly moving towards the second forging cavity 33, thereby avoiding conflicts between the correcting portion 44 and the writing manipulator.

[0050] See Figure 5 、 Figure 6 、 Figure 8 andFigure 10 As shown in the figure: The linkage transmission unit 452 includes a second hinge portion 453, a sleeve 454, and an adjusting rod 455 slidably disposed within the sleeve 454; the front end of the sleeve 454 is hinged to the side wall of the upper die set 21 through the second hinge portion 453; the adjusting rod 455 is slidably disposed within the sleeve 454 and its front end is hinged to the driving rod 451, and forms an acute angle with the driving rod 451.

[0051] When the upper die set 21 is lifted, the sleeve 454 moves upward synchronously under the synchronous lifting action of the upper die set 21, and pulls the adjusting rod 455 synchronously after reaching the maximum stroke. During the process of the adjusting rod 455 being pulled, through the linkage transmission structure, the driving rod 451 generates a synchronous action, thereby driving the reset unit 43 to displace, prompting the sliding rod 42 to slide horizontally towards the second forging cavity 33, and finally enabling the correcting portion 44 to accurately approach and act on the end of the blank, ensuring accurate correction of the blank before forging.

[0052] See Figure 5 and Figure 10 As shown in the figure: The linkage transmission unit 452 further includes a locking member 456 capable of adjusting the telescopic position of the adjusting rod 455, and the locking member 456 is detachably inserted outside the sleeve 454.

[0053] When it is necessary to accurately adjust the driving stroke of the sliding rod 42 during the lifting process of the upper die set 21, the staff can adjust the locking position of the locking member 456 according to the preset driving stroke, so as to control the horizontal sliding stroke of the sliding rod 42 driven by the upper die set 21 during the second-stage lifting.

[0054] Specifically: When the stroke of the adjusting rod 455 extending into the sleeve 454 is longer, the horizontal sliding stroke of the sliding rod 42 increases, so that the correcting portion 44 can be pushed to a farther position, which is applicable to working conditions of longer blanks or requiring a larger correction amplitude.

[0055] When the stroke of the adjusting rod 455 extending into the sleeve 454 is shorter, the horizontal sliding stroke of the sliding rod 42 decreases, causing the correcting portion 44 to stay at a closer position, which is applicable to the needs of shorter blanks or smaller correction amplitudes.

[0056] Through the adjustable structure of the locking member 456 and the adjusting rod 455, precise controllable adjustment of the pushing stroke of the correcting portion 44 is achieved, which can adapt to blanks of different specifications and avoid correction deviations caused by differences in blank sizes.

[0057] A processing technology of a forging device for processing automotive connecting rods, which is applied to a forging device for processing automotive connecting rods, includes the following steps: S1: Use a manipulator to send the heated blank into the first forging cavity 32, and then drive the upper die set 21 to move downward to cooperate with the lower die set 22 to perform preliminary forging on the blank, so that the blank forms a connecting rod blank with a preliminary shape and round handles with different diameters at both ends; S2: The upper die set 21 resets, and the manipulator grabs the preliminarily formed blank and transfers it to the second forging cavity 33; the upper die set 21 is lifted in two stages when lifting: The first stage of lifting: The manipulator completes the transfer of the blank to the second forging cavity 33 to avoid interference between the correction part 44 and the manipulator; The second stage of lifting: The manipulator completely withdraws, and the upper die set 21 synchronously drives the correction module 4 to act during the lifting process; S3: When the correction module 4 is working, it first drives the driving unit 45 to act. During the process of being pulled up by the upper die set 21, the driving unit 45 synchronously conducts pressure to the reset unit 43, and then the reset unit 43 exerts a thrust on the sliding rod 42. Finally, the correction part 44 is pushed towards the second forging cavity 33 through the sliding rod 42, so as to achieve the effect of correcting the blank by using the correction part 44; place the blank in the second forging cavity 33 in the correct posture.

[0058] S4: The upper die set 21 presses down to perform secondary forging on the blank to gradually form the target shape; the upper die set 21 resets, and the manipulator transfers the blank to the third forging cavity 34; finally, the forging is completed.

[0059] The present invention can automatically correct and position the forging position of the blank, with fast correction efficiency and high precision.

[0060] The above embodiments only represent one or several implementation manners of the present invention, and the description is relatively specific and detailed, but it should not be construed as a limitation to the scope of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several deformations and improvements can still be made, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention should be subject to the appended claims.

A processing technology for forging equipment for automobile connecting rod processing, characterized in that: A forging device for processing an automobile connecting rod as claimed in any one of claims 1 to 8, comprising the following steps: S1: using a manipulator to feed the heated blank into a first forging cavity (32), then driving the upper die set (21) to move downward, cooperating with the lower die set (22) to perform preliminary forging on the blank, so that the blank is initially shaped into a connecting rod blank with round handles of different diameters at both ends; S2: the upper die assembly (21) is reset, the robot grasps the initially formed blank, and transfers it to the second forging cavity (33); the upper die assembly (21) is lifted in two stages: the first stage of lifting: the robot completes the transfer of the blank to the second forging cavity (33) to avoid interference between the correction part (44) and the robot; the second stage of lifting: the robot completely withdraws, and the upper die assembly (21) synchronously drives the correction module (4) to move during the lifting process; S3: When the correction module (4) is working, it first drives the driving unit (45) to move. The driving unit (45) transmits pressure to the reset unit (43) in a synchronous process of pulling up through the upper die set (21). Then, a thrust is applied to the sliding rod (42) via the reset unit (43). Finally, the correction part (44) is pushed toward the second forging cavity (33) through the sliding rod (42), thereby achieving the effect of correcting the blank by using the correction part (44); and the blank is placed in the second forging cavity (33) in a correct posture. S4: the upper die assembly (21) presses down to perform secondary forging on the blank, so that it gradually forms a target shape; the upper die assembly (21) is reset, and the robot transfers the blank to the third forging chamber (34); and finally the forging is completed.
