Description

Technical Field

[0001] The invention relates to the technical field of molds, and in particular to a forming device for an aluminum alloy comb hanger forging for a textile machinery. Background Art

[0002] The comb hanger is a device that connects the bottom comb with the comb and other structures in the warp knitting machine. In the high-speed operation of textile, the comb hanger of the warp knitting machine is always in a working environment of strong impact, great wear and high stress. Due to the large force it is subjected to, it is very easy to fail in various ways, which seriously affects the stability of the machine. Therefore, in textile machinery, the comb hanger is required to have greater strength, fatigue resistance and toughness.

[0003] At present, aluminum alloy parts with complex structures, especially those with high requirements for strength and fatigue resistance, such as comb hangers, are mostly made by casting. However, casting will produce problems such as coarse structure, many defects, high casting labor intensity and unstable casting quality, resulting in defects such as short service life of processed parts. Compared with casting, die forging can solve these problems, so the performance of such parts processed by die forging is far greater than that of casting products.

[0004] However, in the prior art, the die forging method can often only be processed at one station at a time, while the actual product needs to be processed sequentially at multiple stations before it can be formed. Therefore, there is a problem of low processing efficiency in the die forging method of the prior art. Summary of the invention

DETAILED DESCRIPTION

[0038] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0039] like Figures 1 to 5 As shown, the present invention provides a forming device for an aluminum alloy comb hanger forging for a textile machinery, comprising a feeding module 1, a forming die 2 and a unloading module 3 which are arranged in sequence;

[0040] The forming die 2 includes an upsetting station, a final forging station and a trimming and punching station, and the working surfaces of the upsetting station, the final forging station and the trimming and punching station are all located on the same forging plane;

[0041] The feeding module 1 includes a first sheet material clamping assembly 4 and an active driving assembly 5. The first sheet material clamping assembly 4 is used to clamp and release the material body on the horizontal plane. The active driving assembly 5 is used to drive the first sheet material clamping assembly 4 to move the material body clamped by the first sheet material clamping assembly 4 along the forging plane. The specific action process is as follows:

[0042] The first sheet metal clamping assembly 4 clamps the material body (mainly clamps the side of the material body), and then the active driving assembly 5 drives the first sheet metal clamping assembly 4 in the clamping state to move along the forging plane. When the active driving assembly 5 transports the material body to the set position, the first sheet metal clamping assembly 4 releases the material body, and then the active driving assembly 5 drives the first sheet metal clamping assembly 4 to return to the initial clamping position, repeating the clamping and releasing process.

[0043] The unloading module 3 includes a second sheet metal clamping assembly 6 and a driven driving assembly 7. The second sheet metal clamping assembly 6 cooperates with the first sheet metal clamping assembly 4 to clamp and release the material body conveyed from the trimming and punching station. The second sheet metal clamping assembly 6 is driven by the driven driving assembly 7 to move the material body clamped by the second sheet metal clamping assembly 6 along the forging plane. The second sheet metal clamping assembly 6 will cooperate with the first sheet metal clamping assembly 4 in the clamping and releasing conveying state.

[0044] The present invention realizes automatic forming and loading of aluminum alloy comb hanger forgings during the forming process by arranging a loading module 1 and a unloading module 3 at both ends of the forging plane of the forming die (that is, the input end and the output end of the material body of the forming die), thereby avoiding manual loading and forging errors that are easily generated during manual loading. The first material plate clamping assembly 4 and the second material plate clamping assembly 6 are jointly driven by the corresponding active drive assembly 5 and the driven drive assembly 7, so that the entire material body is always kept on the forging plane, thereby steadily carrying out the loading and feeding of the forming die 2.

[0045] In order to specifically illustrate the process of the first sheet metal clamping assembly 4 specifically implementing the above-mentioned method, the first sheet metal clamping assembly 4 and the second sheet metal clamping assembly 6 both include two guide plate bodies 8 arranged in mirror symmetry, the guide plate body 8 is perpendicular to the horizontal plane (that is, located on both sides of the forging plane), a guide frame 9 is installed on the guide plate body 8, a guide rail 10 is installed in the middle of the two ends of the guide frame 9, a guide seat 11 for the linear movement of the guide rail 10 is installed on the guide plate body 8, an action frame 12 is installed in the guide frame 9, a runway-shaped rack ring 13 is arranged in the action frame 12, and a lower clamping pad 14 is installed on the inner top of the action frame 12, and the active drive assembly 5 drives the guide plate body 8 to reciprocate linearly under the restriction of the guide seat 11 by meshing with the rack ring 13, wherein the active drive assembly Part 5 is specifically a driving motor, and the position of the active driving component 5 relative to the rack ring 13 is fixed. Then, in the process of the active driving component 5 meshing with the rack ring 13, the diameter of the gear meshing between the active driving component 5 and the rack ring 13 is smaller than the height of the rack ring 13. Under the drive of the active driving component 5, the gear of the active driving component 5 meshes with the rack ring 13, and will drive the action frame 12 to move up and down in the guide frame 9 due to the force. At the same time, the guide frame 9 performs a linear displacement due to the lateral force and the restriction of the guide seat 11; in this way, under the drive of the driving driving component 5, the action frame 12 drives the lower clamping pad 14 to move in a track-like motion trajectory as a whole, so as to complete the reciprocating material conveying of the first sheet material clamping component 4. Among them, the active driving component 5 drives the action frame 12 to perform a reciprocating motion forming a track-like trajectory under the restriction of the linear motion of the guide frame 9 by meshing with the rack ring 13.

[0046] Furthermore, in order to maintain stability during the reciprocating motion in the present invention, the rack ring 13 may be further provided with an active drive assembly 5 , that is, the gears of two symmetrical active drive assemblies 5 are meshed with the rack ring 13 .

[0047] Similarly, the second sheet clamping assembly 6 and the first sheet clamping assembly 4 have the same action, and the main difference is that the lower clamping pad 14 follows the action frame 12, the lower clamping pad 14 contacts the lower surface of the material body, and the vertical movement height of the lower clamping pad 14 is higher than the forging plane. When the lower clamping pad 14 of the first sheet clamping assembly 4 moves to the highest position in the vertical direction, the lower clamping pad 14 of the second sheet clamping assembly 6 is lower than the lower clamping pad 14 of the first sheet clamping assembly 4 in the vertical direction.

[0048] Its main purpose is to make the material body have an inclination angle on the entire forging plane, which is about +20°~-20°, and this inclination angle is in a constant reciprocating change during the action of the action frame 12 (the material body is in a clamping state). Since the material body and the stamping part have a certain "contact viscosity" (that is, the surface of the mold and the material body are bonded during the stamping contact process) during the forging stamping and cutting process, it is easy to cause the mold and the material body to be separated in time during the continuous conveying process, and the conveying of the material body is delayed, which leads to the misalignment of the forging position. Even in the high-precision stamping process, the accumulation of such small errors can easily cause the deviation of the forging position.

[0049] The first sheet metal clamping assembly 4 and the second sheet metal clamping assembly 6, driven by the active drive assembly 5 and the passive drive assembly 7, make the material have an inclination angle on the entire forging plane, and this inclination angle is constantly changing (the main purpose is to make the two ends of the material body have a height difference relative to the forging plane, and this height difference is in reciprocating change. Of course, this height difference is relative to the thickness of the material body and the height of the forging plane), so it is easy to actively separate the material body and the mold.

[0050] It is further explained that, the first sheet material clamping assembly 4 and the second sheet material clamping assembly 6 are driven by the active drive assembly 5 and the passive drive assembly 7 so that the material body has an inclination angle on the entire forging plane, and while this inclination angle is constantly changing, there is a situation where the material body and the forging plane remain consistent. In this case, the clamping action of the upper die frame and the lower die frame is realized.

[0051] In the present invention, when the lower clamping pad 14 is in the reciprocating motion (on the longitudinal plane) forming a runway-like track, as long as the highest height of the lower clamping pad 14 is higher than the forging plane, it can support and convey the material body. In order to further improve the stability during the clamping process, an upper clamping pad 15 is slidably installed on the guide frame 9 located above the lower clamping pad 14, and a rotating rod 17 is installed on the guide frames 9 at both ends of the upper clamping pad 15 through a rotating shaft 16. The rotating shaft 16 is set in the middle position of the rotating rod 17, one end of the rotating rod 17 is connected to the end of the upper clamping pad 15 through a connecting piece, and the rotating rod 17 and the connecting piece are also rotatably connected. The other end of the rotating rod 17 is connected to the top corner of the action frame 12. In this way, when the action frame 12 moves upward in the longitudinal direction of the guide frame 9, the rotating rod 17 drives the upper clamping pad 15 to move downward in the longitudinal direction through the connecting piece, so that the upper clamping pad 15 clamps the upper surface of the material body.

[0052] Furthermore, in the present invention, in order to be able to perform structural stamping of comb hangers at different positions or angles through the same mold structure, for example, holes of the same diameter but at different positions, when the material body enters the final forging forming station, the servo motor 19 is driven to work according to the set angle, so that the material body clamped by the first clamping assembly 4 and the second clamping assembly 6 is rotated at a corresponding angle relative to the overall angle of the forming mold 2 (the position of the forming mold 2 is always fixed), and a rotating seat body 18 and a servo motor 19 for driving the rotating seat body 18 to rotate in a circle are installed at the bottom of the forming mold 2, the first material plate clamping assembly 4 is installed at one end of a certain diameter of the rotating seat body 18, and the second material plate clamping assembly 6 is installed at the other end of the certain diameter. The upsetting die lower die 207, the final forging die lower die 208 and the trimming and punching die 209 are all installed on the lower die frame 202 through the lifting assembly 20. The lifting assembly 20 is used to make the working surface of the upsetting die lower die 207 or the final forging die lower die 208 or the trimming and punching die 209 separate from the forging plane. During this process, the lifting assembly 20 can be used to control the height of the upsetting die lower die 207 and the trimming and punching die 209 to drop below the forging plane, while the final forging die lower die 208 continues to work, thereby completing the forging of multiple holes of the same diameter and in the same circular circumferential direction, and during this process, the position in the length direction can be changed by the conveying function of the first sheet metal clamping assembly 4 and the second sheet metal clamping assembly 6.

[0053] like Figure 2As shown, it is further explained that the lifting component 20 in the present invention can be any existing one that can drive the upsetting die lower die 207, the final forging die lower die 208 and the trimming and punching die 209 to achieve longitudinal lifting, and the lifting height of the lifting component 20 is determined according to the maximum thickness of the material plate. It includes a base 21 and ribs 22 installed on both sides of the base 21, the upper surface of the ribs 22 is provided with a spring group 23, the top of the spring group 23 is connected to the lower die frame 202, and the bottom of the base 21 is provided with a polygonal column 24, and a core shaft 25 is eccentrically installed inside the polygonal column 24. The core shaft 25 rotates under the drive of an external force to increase and decrease the height of the base 21.

[0054] Of course, the present invention requires a corresponding control system to complete the lifting control of the lifting assembly 20 , and the control system includes a program execution module, an image detection module and a control module of the lifting assembly 20 .

[0055] Among them, the program execution module is used to control the clamping frequency of the upper mold frame 201 and the lower mold frame 202 according to the bar production requirements;

[0056] The image detection module is used to collect and detect image data of the forged bar material after the upper die frame 201 and the lower die frame 202 are closed;

[0057] The control module is used to couple the image data collection and detection results of the program execution module and the image detection module to form a control signal for controlling the lifting assembly 20 of the upsetting die lower die 207 or the final forging die lower die 208 or the trimming and punching die 209.

[0058] That is, during the forging process of the aluminum alloy comb hanger, the structure of the comb hanger is usually not a regular structure.

[0059] Furthermore, the present invention provides a forming mold 2, which specifically includes an upper mold frame 201 and a lower mold frame 202. In the present invention, the upper mold frame 201 and the lower mold frame 202 are two basic structures, that is, the upper mold frame 201 and the lower mold frame 202 can move relative to each other under the drive of a power mechanism, thereby producing a forging effect. The power mechanism can be a hydraulic mechanism or other power.

[0060] In this embodiment, a plurality of workstations are arranged between the upper die frame 201 and the lower die frame 202, so that a plurality of workpieces can be processed at different workstations in a set of forming dies. Specifically, an upsetting die upper die 203, a final forging die upper die 204, and a trimming and punching die upper die 205 are fixedly installed at the bottom of the upper die frame 201, and an upsetting die lower die 207, a final forging die lower die 208, and a trimming and punching die lower die 209 are fixedly installed at the top of the lower die frame 202. The upsetting die upper die 203 and the upsetting die lower die 207 are correspondingly arranged to form an upsetting workstation, the final forging die upper die 204 and the final forging die lower die 208 are correspondingly arranged to form a final forging workstation, and the trimming and punching die upper die 205 and the trimming and punching die lower die 209 are correspondingly arranged to form a trimming and punching workstation.

[0061] From the above, it can be seen that by arranging multiple die forging stations in sequence from left to right or from right to left, it is possible to realize multi-station processing. In this embodiment, the die forging stations are arranged according to the processing sequence, that is, the basic die forging processing can be completed after forging processing in sequence, and the next process can be entered.

[0062] Since it is necessary to complete the processing of different processes in multiple stations in the same forming die, and the die forging surfaces of the upsetting station, final forging station and trimming and punching station are all located on the same plane, when setting up different die forging stations, it is necessary to make targeted adjustments to each die forging station in order to achieve a better unified processing effect.

[0063] Specifically:

[0064] The trimming and punching upper die 205 and the upper die frame 201 are fixedly connected via the trimming and punching upper support block 206;

[0065] The trimming and punching lower die 209 and the lower die frame 202 are fixedly connected via a trimming and punching lower support block 210 .

[0066] The lengths of the upper support block 206 and the lower support block 210 for trimming and punching can be adjusted, that is, by adjusting the lengths of the upper support block 206 and the lower support block 210 for trimming and punching, the forging surface between the upper die 205 and the lower die 209 for trimming and punching can be indirectly adjusted, so that it can be coordinated with other workstations.

[0067] Furthermore, the adjustment of the final forging die upper die 204 and the final forging die lower die 208 specifically includes:

[0068] Wedge blocks 211 are provided on both sides of the connection between the upper die 204 of the final forging die and the upper die frame 201, and pressure blocks 212 are provided on the other two sides of the connection;

[0069] Wedge blocks 211 are also provided on both sides of the connection between the lower die 208 of the final forging die and the lower die frame 202, and pressure blocks 212 are also provided on the other two sides of the connection;

[0070] The wedge block 211 and the pressing block 212 cooperate to adjust the postures of the upper die 204 and the lower die 208 of the final forging die.

[0071] The posture here includes the position and angle of the upper die 204 and the lower die 208 of the final forging die, that is, by adjusting the wedge block 211 and the pressure block 212, the processing position and forging angle of the upper die 204 and the lower die 208 of the final forging die can be adjusted to meet the processing of different shapes of different workpieces.

[0072] In addition, the adjustment of the upsetting die upper die 203 and the upsetting die lower die 207 specifically includes:

[0073] The upsetting die upper die 203 and the upper die frame 201 are fixedly connected via a T-shaped block 213 disposed on the upper die frame 201;

[0074] The upsetting die lower die 207 and the lower die frame 202 are fixedly connected via a T-shaped block 213 disposed on the lower die frame 202 .

[0075] The wedge block 211, pressure block 212 and T-block 213 mentioned above are all placed under the die to adjust the die. It should be noted that in this embodiment, the die is completely filled by placing pads under the die, and there is no gap between the die and the die frame, so as to reduce the forging accuracy of the workpiece being affected or the die being damaged due to gaps during the die forging process.

[0076] The above embodiments are only exemplary embodiments of the present application and are not intended to limit the present application. The protection scope of the present application is defined by the claims.
