Description

Technical Field

[0001] The invention relates to the technical field of forging processing, and in particular to a precision forming device and method for a jacquard drawbar forging for a warp knitting machine. Background Art

[0002] In the jacquard machine, the draw rod is an important connecting component in the jacquard machine and plays a vital role. When the jacquard machine is in a state of long-term operation, the draw rod is always in a working environment of strong impact, severe wear and high stress. Since the draw rod is subjected to a large force, various failures are very likely to occur, which seriously affects the stability of the machine. Therefore, the jacquard draw rod is required to have greater strength, fatigue resistance and toughness.

[0003] At present, some jacquard pull rods of warp knitting machines are produced by forging. The production process is mostly cutting, heating, forging, and trimming. The equipment is complex, the process cycle is time-consuming, and the efficiency is low. At the same time, the material utilization rate is also low, which makes it difficult to meet the energy conservation and emission reduction goals strongly advocated by the country at this stage. At the same time, the following problems still exist in the production of jacquard pull rods for warp knitting machines using the forging mode:

[0004] (1) Due to the large number of forging processes, the equipment occupies a large area, the process cycle time is long, and the one-piece method is usually adopted during forging, which is inefficient;

[0060] 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.

[0061] like Figures 1 to 4 As shown, the present invention provides a forming device for a jacquard drawbar forging for a warp knitting machine, characterized in that it comprises:

[0062] The die forging station 1 is used for die forging the rod-shaped material. The die forging station 1 includes an upsetting station 4, a final forging station 5 and a trimming and punching station 6;

[0063] A spraying mechanism 2, which is arranged on the die forging station 1 and is used to continuously spray a water-based release agent into the dies of each station of the die forging station 1;

[0064] A feeding mechanism 3 is provided on the die forging station 1 and is used to transport the blanks after die forging in each station of the die forging station 1 to the lower process;

[0065] Among them, the upsetting station 4, the final forging station 5 and the trimming and punching station 6 are arranged in sequence on the die forging station 1 along the blank processing direction.

[0066] Since forging involves many processes, requires large amounts of equipment, has a long cycle time, and is usually done in a one-piece mold, it is inefficient.

[0067] The present invention performs die forging in a multi-station manner after pre-treating the raw material, and extrudes the raw material at a slower downward speed of the forging press until the raw material fills the cavity of the die, so that different raw materials can be processed differently in the same forming die at the same time to improve the efficiency of die forging.

[0068] Compared with traditional cast pull rods, forged jacquard machine pull rods have better mechanical properties and significantly improve the fatigue resistance of the product. However, the forging processing method has the problem of difficulty in demolding forgings. It is necessary to manually spray water-based demolding agents into the workstation mold continuously during forging, which has high labor costs.

[0069] During the die forging process, the present invention realizes lubrication by continuously and automatically spraying a water-based release agent. After the forged blank is separated from the die, the nozzle can be moved into the inner cavity of the die to automatically spray the surface embedded in the die. The whole process can be completed automatically without manual operation to ensure the quality of the die forging.

[0070] Among them, the tops of the upsetting station 4, the final forging station 5 and the trimming and punching station 6 are all provided with inner cavities for die forging blanks, and inner cavities of the upsetting station 4, the final forging station 5 and the trimming and punching station 6 are all movably provided with inner cavities bases 7 that match the bottom ends of the inner cavities, and the three inner cavities bases 7 are respectively placed at the bottom ends of the inner cavities of the upsetting station 4, the final forging station 5 and the trimming and punching station 6 to form die forging inner cavities corresponding to the die forging processing shapes;

[0071] Among them, three cavity bases 7 can rise in the corresponding cavities;

[0072] Among them, through holes connected to the inner cavity are opened at the bottom center positions of the upsetting station 4, the final forging station 5 and the trimming and punching station 6;

[0073] Among them, the bottom ends of the inner cavities of the upsetting station 4, the final forging station 5 and the trimming and punching station 6 are inclined structures that evenly sink toward the through hole.

[0074] When placing the corresponding processed blanks in the inner cavity of the upsetting station 4, the final forging station 5 and the trimming and punching station 6, they are supported by the three intra-cavity bases 7 in the inner cavity. Then, by controlling the three intra-cavity bases 7 to rise in the inner cavity, the three intra-cavity bases 7 can simultaneously lift the two blanks forged in the upsetting station 4, the final forging station 5 and the trimming and punching station 6 out of the mold, so as to facilitate the subsequent use of the feeding mechanism 3 to transport the four blanks to the next station, among which the blanks after forging in the trimming and punching station 6 will be transported to the cooling device for cooling.

[0075] The die forging station 1 is provided with a longitudinal sliding member 11 capable of longitudinal sliding, and the bottom end of the longitudinal sliding member 11 is provided with a hydraulic cylinder 12 for controlling the lifting and lowering of the longitudinal sliding member 11. The longitudinal sliding member 11 is provided with three connecting rods 13 for respectively passing through the through holes at the bottom ends of the upsetting station 4, the final forging station 5 and the trimming and punching station 6 and extending into the inner cavity;

[0076] Among them, three connecting rods 13 are respectively connected to the cavity base 7 in the inner cavity of the upsetting station 4, the final forging station 5 and the trimming and punching station 6, and the longitudinal sliding member 11 can rise synchronously with the three cavity bases 7 through the three connecting rods 13;

[0077] Among them, a stamping device for stamping directly facing the upsetting station 4, the final forging station 5 and the trimming and punching station 6 is provided at the top of the die forging station 1. When the blank is placed in the inner cavity of the upsetting station 4, the final forging station 5 and the trimming and punching station 6, the die forging process is performed through the stamping device.

[0078] After the blanks are placed in the inner cavities of the upsetting station 4, the final forging station 5 and the trimming and punching station 6, the punching device is started to forge the three blanks at the same time until the blanks are processed in the inner cavity;

[0079] After the blank is processed, the stamping device is controlled to reset, and the output end of the hydraulic cylinder 12 is controlled to extend to raise the height of the longitudinal slide 11 in the die forging station. As the longitudinal slide 11 rises, it will start to rise through three connecting rods together with the three intra-cavity bases 7 until the blank supported on the three intra-cavity bases 7 is lifted out of the mold cavity.

[0080] The feeding mechanism 3 includes a track base 31 fixed on the die forging station 1, a track slide 32 capable of stepping along the track base 31 is arranged on the side of the track base 31, and three groups of clamping mechanical arms 33 for clamping the blank are arranged on the track slide 32;

[0081] The orientation of the rail base 31 on the die forging station 1 is consistent with the direction of blank processing;

[0082] Among them, the three groups of clamping mechanical arms 33 are respectively located above the upsetting station 4, the final forging station 5 and the trimming and punching station 6 on the track slide 32, and as the track slide 32 moves on the track base 31, the three groups of clamping mechanical arms 33 can be moved to the upper part of the lower station;

[0083] A space is formed between any two clamping mechanical arms 33 for the die forging punch head on the die forging station 1 to descend.

[0084] After the three blanks are lifted out of the mold cavity of the workstation, the three clamping arms 33 of the feeding mechanism 3 are first controlled to clamp the three blanks, and then the track slide 32 is controlled to move on the track base 31 until the blank on the upsetting station 4 moves to the final forging station 5, and the blank on the final forging station 5 moves to the trimming and punching station 6, and the blank on the trimming and punching station 6 moves to the lower cooling device.

[0085] At this time, the three clamping robotic arms 33 are controlled to release the blank, so that the blank that needs multiple processing can be automatically transferred to the next forging station for secondary forging after one forging, and can be automatically transferred to the next forging station for tertiary forging after the secondary forging, and can be automatically transferred to the next level for cooling after the tertiary forging.

[0086] After the feeding mechanism 3 completes the transfer of the blank, the output end of the hydraulic cylinder 12 can be controlled to reset, so that the three cavity bases 7 are lowered into the corresponding mold cavities again.

[0087] The spraying mechanism 2 includes three groups of inner cavity spraying mechanisms 21 and three groups of bottom die spraying mechanisms 22 for spraying, and a liquid storage device 23 arranged on the die forging station 1 for storing a water-based mold release agent. The output port of the liquid storage device 23 is connected to a pumping device 24 for pumping the water-based mold release agent to each inner cavity spraying mechanism 21 and each bottom die spraying mechanism 22;

[0088] Three groups of inner cavity spraying mechanisms 21 are respectively arranged on the outside of three connecting rods 13. The inner cavity spraying mechanisms 21 can extend into the inner cavity of the upsetting station 4, the final forging station 5 or the trimming and punching station 6 along with the connecting rods 13. The inner cavity spraying mechanisms 21 are used to evenly spray the water-based release agent on the wall of the inner cavity.

[0089] Among them, three groups of bottom mold spraying mechanisms 22 are arranged on the track slide 32 and located on one side of each clamping robot arm 33. When the clamping robot arm 33 clamps the blank and moves to the lower workstation, the corresponding bottom mold spraying mechanism 22 moves with the track slide 32 to spray the water-based release agent facing the base 7 in the cavity.

[0090] The inner cavity spraying mechanism 21 is composed of two symmetrical arc-shaped water boxes 211. The two arc-shaped water boxes 211 can be combined to form a pipe-mounted structure and be clamped on the outside of the connecting rod 13.

[0091] The interior of the arc-shaped water box 211 is a hollow structure, and the bottom ends of the two arc-shaped water boxes 211 are connected to the pumping device 24 through a first hose 212, and a plurality of first spray heads 213 for spraying a water-based release agent are evenly distributed on the outside of the two arc-shaped water boxes 211;

[0092] The diameter of the two arc-shaped water boxes 211 after merging is smaller than the through holes at the bottom of the upsetting station 4 , the final forging station 5 and the trimming and punching station 6 .

[0093] When the hydraulic cylinder 12 controls the three connecting rods 13 to continuously extend into the inner cavity of the mold, the inner cavity spraying mechanism 21 respectively clamped on the three connecting rods 13 will extend into the inner cavity of the mold simultaneously with the connecting rods until the connecting rods 13 stop extending. At this time, the inner cavity spraying mechanism 21 composed of two arc-shaped water boxes 211 is in the inner cavity of the mold.

[0094] The pumping device 24 is controlled to pump the water-based release agent into each arc-shaped water box 211 through multiple first hoses 212, and the excess water-based release agent in the arc-shaped water box 211 will be evenly sprayed toward the inner cavity surface of the mold through multiple first nozzles 213. After the connecting rod 13 is reset, the inner cavity spraying mechanism 21 is moved out of the mold cavity and is not easily affected by high temperature.

[0095] Among them, the bottom mold spraying mechanism 22 includes a metal bellows 221 fixed on the track slide 32, the interior of the metal bellows 221 is connected to the pumping device 24 through a second hose 222, and a second nozzle 223 for spraying a water-based release agent is arranged at the end of the metal bellows 221.

[0096] During the process of the feeding mechanism 3 transferring three blanks, the clamping robot arm 33 will be transferred from the current workstation to the adjacent lower-level workstation. At the same time, the bottom mold spraying mechanism 22 arranged on one side of the clamping robot arm 33 will move with the track slide 32 to a position facing the base 7 in the cavity.

[0097] At this time, the water-based mold release agent is pumped into the multiple second hoses 222 by controlling the pumping device 24, so that the water-based mold release agent will be sprayed out from the second nozzle 223 through the metal bellows 221. By adjusting the direction of the metal bellows 221, the sprayed water-based mold release agent can be directed to the upper surface of the inner base 7 of the cavity that supports the blank at this time, thereby completing automatic spraying.
