Description

Technical Field

[0001] This invention relates to the field of steel cord processing technology, and in particular to a novel steel cord pressing die. Background Technology

[0002] A steel cord pressing die is a mold made of ultra-hard material with precision-shaped holes, used to plastically deform high-carbon steel wire during the drawing process to achieve the required diameter, surface finish and mechanical properties.

[0003] A search revealed a Chinese patent with publication number CN216947627U, which discloses a steel wire rope rotary pressing die, including a base, a compaction component on the base, and a pressing die support disc. The working surface of the pressing die support disc has four pressing die grooves, and a pressing die is slidably connected in each of the pressing die grooves.

[0004] Based on the above research and combined with the actual problems, it was found that: This pressing device uses several small pressing dies, each with an arc-shaped hole at one end. When the several small pressing dies are combined, the arc-shaped holes can be combined into a complete circular hole. The several small pressing dies can provide more uniform extrusion pressure to the steel cord. However, in actual use, the steel cord needs to slide inside the arc-shaped holes. Long-term sliding friction will cause a large amount of metal powder to accumulate in the arc-shaped holes. The powder will increase the friction between the steel cord and the pressing die, thereby increasing the wear of both, shortening the service life of the pressing die, and easily scratching the surface of the steel cord. Moreover, this pressing device is not convenient for cleaning the powder inside the arc-shaped holes. Cleaning requires disassembling the entire pressing device, which greatly prolongs the downtime of the twisting machine and reduces the processing efficiency of the steel cord. Summary of the Invention

[0005] The purpose of this invention is to provide a novel steel cord pressing die to solve the problems mentioned in the background art.

[0006] The technical solution of the present invention is as follows: a novel steel cord pressing mold, comprising a housing, wherein a through hole is provided inside the housing, and a plurality of sliding plates are slidably connected through the through hole. One end of each sliding plate is rotatably connected to a rotating shaft. An angle positioning mechanism is provided between each rotating shaft and a corresponding sliding plate. A pressing module is fixedly provided at one outer end of each rotating shaft, and a gear is rotatably provided at the other outer end of each rotating shaft in one direction. A rack is fixed at the position corresponding to each gear on the inner side of the through hole. Each gear meshes with the rack at the corresponding position. Arc-shaped grooves are provided on all edges of each pressing module. The invention also includes a separation and merging mechanism for driving all sliding plates to move synchronously. An air jet flushing mechanism is also provided between each rotating shaft and each pressing module.

[0007] Preferably, the separation and merging mechanism includes a worm wheel disposed inside the housing, a hollow worm rotatably disposed inside the housing, and a plurality of sliding pins fixed inside each slide plate. The worm wheel is rotatably connected to the inside of the housing via a bearing. The worm wheel meshes with the hollow worm. One end of the worm wheel is provided with an oblique sliding groove corresponding to the position of each sliding pin. Each sliding pin is slidably adapted to the inner side of the oblique sliding groove at the corresponding position.

[0008] Preferably, a worm shaft is rotatably connected through the lower inner side of the housing, the hollow worm is fixedly sleeved on the outer side of the worm shaft, and a hexagonal groove is provided at one end of the worm shaft.

[0009] Preferably, each gear is unidirectionally rotatably connected to the corresponding shaft via a one-way bearing.

[0010] Preferably, the angle positioning mechanism includes a square groove formed at the lower end of the slide plate and a rotating block fixed to the outside of the rotating shaft. The rotating block has several guide grooves arranged in a circle inside. Each guide groove has a plate slidably inserted inside. One end of each plate is elastically connected to the inner side of the corresponding guide groove by a spring.

[0011] Preferably, each of the four corners of the square groove is provided with an arc-shaped surface, and the other end of each insert plate is rotatably connected to a roller, the radius of each roller being equal to the radius of each arc-shaped surface.

[0012] Preferably, the jet flushing mechanism includes a tube rotatably inserted inside each pressure module, with multiple tube air holes on the outer side of each tube, and one end of each tube connected to an annular connecting pipe via a connecting air pipe, and also includes an air source device for blowing air into the annular connecting pipe.

[0013] Preferably, the gas source device includes a gas storage tank and a gas pump, the gas pump outlet is connected to the inside of the gas storage tank, and the gas storage tank outlet is connected to the inside of an annular connecting pipe through a manual valve.

[0014] Preferably, the jet flushing mechanism further includes pressure module air holes formed inside each pressure module and communicating with each arc-shaped groove, and the other ends of the plurality of pressure module air holes are respectively aligned with the insertion tube air holes at corresponding positions.

[0015] Preferably, the plurality of vent holes on each cannula are located at positions away from the center of the through hole.

[0016] This invention provides a novel steel cord pressing die, which, compared with the prior art, has the following improvements and advantages:

[0017] Firstly, this invention uses a separation and merging mechanism to drive several sliding plates to separate or merge, thereby causing several pressing modules to rotate 90° simultaneously in one go. This causes the arc-shaped grooves on several pressing modules, which were originally facing the center of the through hole, to rotate to one side and switch positions. Adjacent arc-shaped grooves rotate from the side to face the center of the through hole, achieving the function of quickly switching the position of the arc-shaped grooves. The arc-shaped grooves that were originally covered with powder are switched to the side, making it convenient for workers to clean the powder on the inner surface of the arc-shaped grooves. This allows for rapid cleaning of the inner surface of the arc-shaped grooves without stopping the machine, thus preventing the processing efficiency of steel cord from being affected by cleaning the pressing mold.

[0018] Secondly, the present invention uses a jet flushing mechanism to spray high-speed airflow onto the inner surface of the unmerged arc-shaped grooves on each pressure module. The high-speed airflow can help to disperse the powder on the surface of each arc-shaped groove, further improving the convenience of cleaning the arc-shaped grooves and improving the cleaning effect and efficiency.

Detailed Implementation

[0032] The present invention will now be described in detail, and the technical solutions in the embodiments of the present invention will be clearly and completely described. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0033] This invention provides a novel steel cord pressing die through improvements. The technical solution of this invention is as follows:

[0034] Example 1:

[0035] like Figures 1 to 10 As shown, this embodiment of the invention provides a novel steel cord pressing mold, including a housing 1. A through hole 2 is provided inside the housing 1. Several sliding plates 3 are slidably connected through the through hole 2. One end of each sliding plate 3 is rotatably connected to a rotating shaft 4. An angle positioning mechanism is provided between each rotating shaft 4 and the corresponding sliding plate 3. A pressing module 5 is fixedly provided at one outer end of each rotating shaft 4. A gear 7 is rotatably provided at the other outer end of each rotating shaft 4. Each gear 7 is rotatably connected to the corresponding rotating shaft 4 via a one-way bearing 9. A rack 8 is fixed at the position corresponding to each gear 7 on the inner side of the through hole 2. Each gear 7 meshes with the corresponding rack 8. Arc-shaped grooves 6 are provided on all edges of each pressing module 5. The invention also includes a separation and merging mechanism that drives all sliding plates 3 to move synchronously. An air jet flushing mechanism is also provided between each rotating shaft 4 and each pressing module 5.

[0036] Furthermore, the separation and merging mechanism includes a worm gear 101 disposed inside the housing 1, a hollow worm 105 rotatably disposed inside the housing 1, and several sliding pins 104 fixed inside each slide plate 3. The worm gear 101 is rotatably connected to the inside of the housing 1 via a bearing 102. The worm gear 101 meshes with the hollow worm 105. One end of the worm gear 101 is provided with a slanted groove 103 corresponding to the position of each sliding pin 104. Each sliding pin 104 is slidably adapted to the inner side of the slanted groove 103 at the corresponding position. A worm shaft 106 is rotatably connected through the lower inner end of the housing 1. The hollow worm 105 is fixedly sleeved on the outer side of the worm shaft 106. One end of the worm shaft 106 is provided with a hexagonal groove.

[0037] The separation and merging mechanism drives all the slide plates 3 to separate or merge, thereby causing all the pressing modules 5 to rotate 90° simultaneously in one go. This causes the arc-shaped grooves 6 on all the pressing modules 5 that were originally facing the center of the through hole 2 to rotate to one side and switch positions. The adjacent arc-shaped grooves 6 rotate from the side to face the center of the through hole 2, thus achieving the function of quickly switching the position of the arc-shaped grooves 6. All the arc-shaped grooves 6 that were originally filled with powder are switched to the side, making it convenient for the staff to clean the powder on the inner surface of the arc-shaped grooves 6. This allows for quick cleaning of the inner surface of the arc-shaped grooves 6 without stopping the machine, thereby preventing the processing efficiency of the steel cord from being affected by cleaning the pressing mold.

[0038] Furthermore, the angle positioning mechanism includes a square groove 201 formed at the lower end of the slide plate 3 and a rotating block 202 fixed to the outside of the rotating shaft 4. The rotating block 202 has a series of guide grooves 203 arranged in a circular pattern inside. Each guide groove 203 has a plate 204 slidably inserted into its inner side. One end of each plate 204 is elastically connected to the inner side of the corresponding guide groove 203 by a spring 205. An arc surface 207 is provided at each of the four corners of the square groove 201. The other end of each plate 204 is rotatably connected to a roller 206. The radius of each roller 206 is equal to the radius of each arc surface 207.

[0039] By using the angle positioning mechanism, when all the pressure modules 5 are rotated, a certain torque can be applied to the rotating block 202, which can automatically rotate the rotating block 202 to a 90° angle, thereby driving the rotating shaft 4 and the pressure module 5 to rotate precisely to a 90° angle, thus improving the angle switching accuracy of all the pressure modules 5.

[0040] Furthermore, the jet flushing mechanism includes a tube 301 rotatably inserted inside each pressure module 5. Multiple tube air holes 302 are opened on the outer side of each tube 301, and one end of each tube 301 is connected to an annular connecting pipe 306 through a connecting air pipe 304. It also includes an air source device for blowing air into the inside of the annular connecting pipe 306. The air source device includes an air tank 307 and an air pump 308. The air outlet of the air pump 308 is connected to the inside of the air tank 307. The air outlet of the air tank 307 is connected to the inside of the annular connecting pipe 306 through a manual valve 309. The jet flushing mechanism also includes a pressure module air hole 303 opened inside each pressure module 5 and connected to each arc groove 6. The other end of the multiple pressure module air holes 303 is aligned with the corresponding tube air holes 302.

[0041] The jet flushing mechanism can spray high-speed airflow onto the inner surface of the unmerged arc grooves 6 on each pressure module 5. The high-speed airflow can help to blow away the powder on the surface of each arc groove 6, further improving the convenience of cleaning the arc grooves 6 and improving the cleaning effect and efficiency.

[0042] Furthermore, the multiple vent holes 302 on each cannula 301 are all located at positions away from the center of the through hole 2;

[0043] The pressure module is quadrilateral in shape, and there are four pressure modules in total;

[0044] It should be noted that the multiple insertion tube air holes 302 located on each insertion tube 301 are all opened at a position far away from the center of the through hole 2. Therefore, the compressed air inside the insertion tube 301 will not be sprayed through the pressure module air hole 303 towards the arc-shaped groove 6 facing the center of the through hole 2. That is, there will be no high-speed airflow spraying on the inner surface of the several arc-shaped grooves 6 that make up the whole circular hole, so as to avoid affecting the process of the pressure mold extruding the steel cord.

[0045] Example 2: The pressing module is triangular in shape, and there are two pressing modules. The number of pressing dies 5 can also be two. The cross-section of the two pressing dies 5 is an equilateral triangle, and each pressing die 5 has an arc-shaped groove 6 at the midpoint of its three sides (e.g., Figure 9 , 10 As shown), when one side of the two molds 5 is close to each other, the two semi-circular arc grooves 6 in the middle of the two sides can be combined to form a complete circular hole.

[0046] The number of the connecting slide plate 3, gear 7, rack 8, and connecting air pipe 304 of the connecting mold 5 is also two. The separation and merging mechanism can drive the mold 5 to rotate 120° each time, so that one side of the two molds 5 is in contact, and the two adjacent arc grooves 6 are combined to form a new round hole.

[0047] Working principle: During use, the entire pressing die is installed on the steel cord twisting machine. The twisting machine pulls out the twisted steel cord and passes it through the through hole 2. During adjustment, an Allen wrench is inserted into the hexagonal groove to rotate the worm shaft 106. The worm shaft 106 drives the hollow worm 105 of the separation and merging mechanism to rotate. The hollow worm 105 drives the worm wheel 101 to rotate. The worm wheel 101 drives the multiple inclined slide grooves 103 at one end to rotate, causing the worm wheel 101 to drive all the inclined slide grooves 103 to rotate counterclockwise by a certain angle (e.g., Figure 3 As shown), all sliding pins 104 are respectively adapted to slide on the inner side of all inclined sliding grooves 103. When all inclined sliding grooves 103 rotate counterclockwise, a thrust pointing towards the center of the through hole 2 can be applied to all sliding pins 104, thereby pushing all sliding plates 3 to move and merge synchronously towards the center of the through hole 2. All sliding plates 3 respectively drive all pressing modules 5 to merge. After all pressing modules 5 merge, all arc grooves 6 on one side of all pressing modules 5 merge to form a complete circular hole. This circular hole can squeeze the twisted steel cord to make the cross section of the steel cord form a specific shape.

[0048] In actual use, the steel cord slides into the round hole from one end, and after being squeezed by all the pressing modules 5, it slides out from the other end of the round hole. During this process, the steel cord rubs against the surface of the arc groove 6 on the side of the pressing module 5, which will cause the surface material of the arc groove 6 to wear and produce powder. In order to prevent the powder from increasing the sliding friction of the steel cord and to avoid aggravating the wear of the steel cord and the arc groove 6, it is necessary to clean the powder accumulated on the surface of the arc groove 6 regularly.

[0049] During the cleaning operation, rotating the worm shaft 106 and the hollow worm 105 drives the worm wheel 101 to rotate, causing the worm wheel 101 to drive all the inclined grooves 103 at one end to rotate clockwise (e.g., Figure 2As shown, through the sliding engagement between all sliding pins 104 and all inclined slides 103, all slide plates 3 can be simultaneously separated. All slide plates 3 respectively drive all pressing modules 5 and all rotating shafts 4 to move away from the center point of the through hole 2 simultaneously. All rotating shafts 4 respectively drive all gears 7 to simultaneously separate. When all gears 7 are in contact with all racks 8, they can drive all gears 7 to rotate at a certain angle (adjusted according to actual dimensions, the rotation angle of gears 7 can be close to 90°). Since gears 7 and rotating shafts 4 are connected by a one-way bearing 9, the rotational torque when all gears 7 are separated can be transmitted to all rotating shafts 4 through the one-way bearing 9. All rotating shafts 4 respectively drive all pressing modules 5 to rotate at an angle close to 90°. The arc-shaped grooves 6 on all pressing modules 5 that were originally facing the center of the through hole 2 rotate to one side to switch positions. The adjacent arc-shaped grooves 6 rotate from the side to face the center point of the through hole 2. The through hole 2 is located at the center, thus enabling rapid switching of the arc groove 6 position. All adjacent arc grooves 6 combine to form a new circular hole. When all slide plates 3 are separated to their farthest point, the worm shaft 106 is rotated in the opposite direction, causing all slide plates 3 to merge again. All slide plates 3 drive all gears 7 to merge, and all gears 7 mesh with all racks 8, causing all gears 7 to rotate in the opposite direction when they merge. At this time, the reverse rotation torque of all gears 7 cannot be transmitted to the rotating shaft 4 and the pressing module 5, thus preventing all pressing modules 5 from rotating in the opposite direction. When all pressing modules 5 merge again, all adjacent arc grooves 6 combine to form a new circular hole. All arc grooves 6 that were originally filled with powder are switched to the side, making it convenient for workers to clean the powder on the inner surface of the arc grooves 6. The inner surface of the arc grooves 6 can be cleaned quickly without stopping the machine, thus preventing the processing efficiency of steel cord from being affected by cleaning the pressing mold.

[0050] To ensure that the rotation angle of the pressure module 5 is close to 90° during each position change, thereby allowing all adjacent arc-shaped grooves 6 to precisely assemble into a complete circular hole, an angle positioning mechanism is installed on the outside of the rotating shaft 4. When the gear 7 drives the rotating shaft 4 to rotate, the rotating shaft 4 drives the rotating block 202 to rotate. The rotating block 202 drives all the insert plates 204 inside it to rotate. All the insert plates 204 drive all the rollers 206 to roll along the inner side of the square groove 201. When the rotating block 202 drives all the insert plates 204 to rotate within the range of 0°-45°, all the insert plates 204 drive all the rollers 206 to roll from the inner surface of all the arc surfaces 207 towards the midpoint of all the sides of the square groove 201. This process causes all the insert plates 204 to slide towards the inner side of all the guide grooves 203 and compress all the springs 205. When the rotating block 202 drives all the insert plates 204 to rotate within the range of 45°, the rotation angle is adjusted accordingly. When rotating within a range of -90°, all insert plates 204 drive all rollers 206 to roll from the midpoint of all sides of all square slots 201 to the position of all arc surfaces 207. During this process, all springs 205 release their elastic force to push all insert plates 204 outward. All insert plates 204 drive all rollers 206 to press against all sides of the square slots 201. At this time, there is an angle between the insert plates 204 and all sides of the square slots 201, and all insert plates 204 have an outward pushing force. Therefore, a certain rotational torque can be applied to the rotating block 202, causing the rotating block 202 to rotate from 45° to 90°. During this process, all rollers 206 roll to the inner surface of the adjacent arc surfaces 207, which can make the rotating block 202 automatically rotate to a 90° angle, thereby driving the rotating shaft 4 and the pressure module 5 to rotate precisely to a 90° angle, improving the angle switching accuracy of all pressure modules 5.

[0051] By setting up a jet flushing mechanism, the air pump 308 can fill the inside of the air tank 307 with compressed air when it is running. After several pressure modules 5 rotate 90°, several arc-shaped grooves 6 that were originally filled with powder rotate to the side. The air outlet of the air tank 307 is controlled by the manual valve 309, so that the compressed air inside the air tank 307 enters the annular connecting pipe 306. It then enters the inside of all connecting air pipes 304 evenly through the annular connecting pipe 306, and then enters the inside of all insertion tubes 301 evenly. Finally, it flows into the inside of the multiple pressure module air holes 303 inside all pressure modules 5 through the multiple insertion tube air holes 302 on the side wall of all insertion tubes 301. Finally, it is sprayed onto the inner surface of each arc-shaped groove 6 through one end of the multiple pressure module air holes 303. The high-speed airflow can help to blow away the powder on the surface of each arc-shaped groove 6, which further improves the convenience of cleaning the arc-shaped grooves 6 and improves the cleaning effect and cleaning efficiency.

[0052] It should be noted that the multiple insertion tube air holes 302 located on each insertion tube 301 are all located at a position far away from the center of the through hole 2. Therefore, the compressed air inside the insertion tube 301 will not be sprayed through the pressure module air hole 303 toward the arc-shaped groove 6 facing the center of the through hole 2. That is, there will be no high-speed airflow spraying on the inner surface of all the arc-shaped grooves 6 that make up the whole circular hole, so as to avoid affecting the process of the pressure mold extruding the steel cord.

Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the invention. Therefore, the invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
