Description

Technical Field

[0001] The present invention relates to the technical field of steel wire surface treatment, and in particular to a roughness adjustment device for the surface treatment of rubber hose steel wire. Background Art

[0002] Rubber hose steel wire is a steel wire material used to enhance the strength and durability of rubber hoses. The main function of rubber hose steel wire is to be embedded in the inner or outer layer of the rubber hose to enhance the compressive, tensile, and impact resistance of the rubber hose, enabling it to withstand high pressure, high temperature, and use in harsh environments.

[0003] In the production of rubber hose steel wire, it is necessary to polish the surface of the rubber hose steel wire to make its surface have a certain roughness, which can enhance the bonding performance between the steel wire and the rubber hose, optimize the stress distribution, and improve the durability, reliability, and production efficiency of the rubber hose.

[0004] After retrieval, a Chinese patent with the authorization announcement number: CN115519414B discloses a device for adjusting the surface roughness of rubber hose steel wire, including a base, and a rotating mechanism, a positioning structure, and a cleaning mechanism are cooperatively arranged on the top surface of the base; the rotating mechanism includes a first vertical plate, a first through hole is opened on one side of the first vertical plate, an annular groove is opened on one side of the first vertical plate, the annular groove is concentric with the first through hole, and a sliding block is cooperatively arranged in the annular groove, and the outer tooth gear ring is fixedly connected between one sides of the sliding blocks.

[0005] Based on the above retrieval and combined with practical problems, it is found that: this device increases the surface roughness of the rubber hose steel wire by polishing the surface of the rubber hose steel wire with a wire brush. However, in actual use, it is very difficult to achieve more precise polishing by the method of polishing with a wire brush. Affected by factors such as the deformation of the wires of the wire brush, it is very difficult to provide a more uniform polishing treatment for the surface of the rubber hose steel wire, resulting in uneven roughness at each position on the surface of the rubber hose steel wire, which affects the bonding performance between the rubber hose steel wire and the rubber hose.

[0017] The present invention provides a roughness adjusting device for the surface treatment of hose steel wires through improvement. Compared with the prior art, it has the following improvements and advantages:

[0018] First: The present invention drives the steel wire on the outer side of the steel wire release roller towards the position of the steel wire winding roller by rotating the steel wire winding roller, so that the steel wire uniformly passes through the inner sides of the two rotating cylinders. At the same time, the driving mechanism drives the two grinding mechanisms to rotate in opposite directions. When the multiple abrasive belts in the grinding mechanisms rotate around the outer side of the steel wire, the surface of the abrasive belt will generate friction with the surface of the steel wire, playing a role in grinding. At the same time, when the two grinding mechanisms rotate in opposite directions to grind the steel wire, spiral patterns that cross each other can be ground on the surface of the steel wire, thereby improving the uniformity of the patterns on the surface of the steel wire, making the roughness of each position on the surface of the steel wire more uniform, and thus improving the processing quality of the steel wire.

While the multiple abrasive belts rotate around the outer side of the steel wire, the abrasive belts can also move rapidly back and forth along the extension direction of the steel wire, thereby further improving the uniformity of the patterns on the surface of the steel wire, making the roughness of each position on the surface of the steel wire more uniform.

[0020] Thirdly: Through the winding mechanism of the present invention, when the rotating cylinder rotates one circle, the abrasive belt outside the abrasive belt release roller can be wound around the outside of the abrasive belt take-up roller by a certain length, so that the abrasive belt with reduced roughness after grinding on the outside of the abrasive belt support rod is wound onto the outside of the abrasive belt take-up roller, and the unworn abrasive belt outside the abrasive belt release roller is transferred to the outside of the abrasive belt support rod. Therefore, the position where the abrasive belt contacts the steel wire always maintains good roughness, so that the steel wire surface can be continuously polished well, further improving the uniformity of the surface texture of the steel wire after grinding and making the roughness of each position on the steel wire surface more uniform.

[0033] The present invention will be described in detail below. The technical solutions in the embodiments of the present invention are clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.

[0034] The present invention provides a roughness adjusting device for surface treatment of hose steel wires through improvement. The technical solution of the present invention is as follows:

[0035] As Figures 1 to 9As shown in the figure, an embodiment of the present invention provides a roughness adjustment device for the surface treatment of hose steel wires, including a bottom plate 1 and a U-shaped frame 2 on its upper side. Two guide wheel frames 15 are fixed at both ends of the upper side of the bottom plate 1, and two guide wheels 16 are rotatably connected to the upper ends of the two guide wheel frames 15. It further includes: two grinding mechanisms symmetrically arranged at both ends of the U-shaped frame 2; the grinding mechanism includes a rotating cylinder 3 rotatably connected through one end of the U-shaped frame 2, a plurality of notches 4 are arranged on the outer side of the rotating cylinder 3, a column 5 is fixed at one end of each notch 4, and a fork rod 7 is movably arranged on one side of each column 5 through a reciprocating mechanism. A grinding belt 6 is wound inside each fork rod 7 through a winding mechanism; it further includes a driving mechanism for driving the two rotating cylinders 3 to rotate in opposite directions; the driving mechanism includes a driving motor 101 installed on the lower side of the U-shaped frame 2, two rotating shafts 102 rotatably connected through both ends of the U-shaped frame 2, and two rotating cylinder belt pulleys 103 fixed at one end of the outer side of the two rotating cylinders 3 and located inside the U-shaped frame 2. The outer sides of the two rotating shafts 102 are both fixed with first rotating shaft belt pulleys 104, and the two first rotating shaft belt pulleys 104 are respectively connected to the two rotating cylinder belt pulleys 103 through belts. One end of each of the two rotating shafts 102 is fixed with a driven bevel gear 106, and the driving end of the driving motor 101 is fixed with a driving bevel gear 105 meshing with the two driven bevel gears 106.

[0036] Further, the reciprocating mechanism includes a rotating wheel 203 rotatably sleeved on one end of the outer side of the rotating cylinder 3, a second rotating shaft belt pulley 202 fixed at one end of the rotating shaft 102, a guide groove 204 opened at one end of each column 5. A slider 205 is slidably connected to the inner side of each guide groove 204, and a sliding rod 206 is slidably inserted through the inside of each slider 205. One end of each sliding rod 206 is fixed to the fork rod 7 at the corresponding position. A wavy chute 208 is arranged on the outer side of the rotating wheel 203, and a sliding pin 207 that is movably adapted to the inner side of the wavy chute 208 is rotatably connected to one end of each sliding rod 206. A turntable belt pulley 201 (as shown in Figure 5 the figure) is fixed at one end of the rotating wheel 203, and the turntable belt pulley 201 is connected to the second rotating shaft belt pulley 202 through a belt;

[0037] Through the reciprocating mechanism, while the plurality of grinding belts 6 rotate around the outer side of the steel wire, the grinding belts 6 can also make a rapid reciprocating movement along the extension direction of the steel wire, thereby further improving the uniformity of the surface texture of the steel wire, and making the roughness of each position on the steel wire surface more uniform.

[0038] Further, the diameter of the first rotating shaft belt pulley 104 is smaller than the diameter of the rotating cylinder belt pulley 103, and the diameter of the second rotating shaft belt pulley 202 is larger than the diameter of the turntable belt pulley 201;

[0039] When the rotating shaft 102 in the driving mechanism rotates, it can drive the rotating drum pulley 103 to rotate at a slower speed, thereby driving the rotating drum 3 to rotate at a slower speed, and the rotating shaft 102 can drive the rotating wheel 203 of the reciprocating mechanism to rotate at a faster speed, thereby increasing the frequency of the reciprocating movement of the fork rod 7 and the grinding belt 6, and improving the grinding efficiency of the hose wire.

[0040] Furthermore, one end of each slider 205 is elastically connected to one end of the inner side of the guide slot 204 at the corresponding position through a pressure spring 209;

[0041] The pressure spring 209 applies a certain pressure to the slider 205. After the slider 205 is pressed, the pressure is transmitted to the fork rod 7 and the frosted belt 6 through the slide rod 206, so that a certain pressure is maintained between the frosted belt 6 and the hose wire, so that a relatively uniform texture is formed on the surface of the hose wire.

[0042] Furthermore, the winding mechanism includes a sanding belt winding roller 301 and a sanding belt releasing roller 302 rotatably connected to the inner side of the fork rod 7, a sanding belt supporting rod 303 fixed to the inner end of the fork rod 7, and a friction plate 308 fixed to one end of the U-shaped frame 2. The sanding belt 6 is wound on the outer side of the sanding belt winding roller 301 and the sanding belt releasing roller 302, and the sanding belt 6 is slidably adapted to the outer side of the sanding belt supporting rod 303. A friction wheel 307 is fixed to one end of the sanding belt winding roller 301, and a one-way locking mechanism is provided between one end of the sanding belt winding roller 301 and the fork rod 7. The one-way locking mechanism includes a ratchet 305 rotatably connected to the outer side of the fork rod 7 and a ratchet 304 fixed to one end of the sanding belt winding roller 301. One end of the ratchet 305 is elastically connected to the fork rod 7 through a torsion spring 306.

[0043] Through the winding mechanism, when the drum 3 rotates one circle each time, the sanding belt 6 on the outer side of the sanding belt release roller 302 can be wound toward the outer side of the sanding belt winding roller 301 for a certain length, so that the sanding belt 6 with reduced roughness after grinding on the outer side of the sanding belt support rod 303 is wound toward the outer side of the sanding belt winding roller 301, and the sanding belt 6 on the outer side of the sanding belt release roller 302 that has not been worn is transferred to the outer side of the sanding belt support rod 303. Therefore, the position where the sanding belt 6 contacts the steel wire always maintains a good roughness, so that the surface of the steel wire can be continuously polished well, further improving the uniformity of the surface texture of the steel wire after grinding, and making the roughness of each position of the steel wire surface more uniform.

[0044] Furthermore, a fixing cylinder 309 is fixed on the outer side of the fork rod 7 at the position of the abrasive belt release roller 302, and the inner side of the fixing cylinder 309 is elastically connected to the abrasive belt release roller 302 via a clockwork spring 310;

[0045] The clockwork spring 310 can apply a certain torsional torque to the sanding belt release roller 302, and the direction of the torsional torque is opposite to the rotation direction of the sanding belt release roller 302. Therefore, when the sanding belt 6 pulls the sanding belt release roller 302 to rotate, the sanding belt release roller 302 will be subjected to a certain reaction force, thereby applying a certain reverse pulling force to the sanding belt 6, so that the sanding belt 6 can be in a taut state, so that the sanding belt 6 can be tightly attached to the outer side of the sanding belt support rod 303, preventing the sanding belt 6 from sliding and deviating, so that the sanding belt 6 is more stable when grinding the steel wire surface, and the texture of the steel wire surface is more uniform.

[0046] Furthermore, a circular frame 8 is fixed at the middle section of the U-shaped frame 2, and three positioning wheel frames 9 arranged in a circumference are fixed to the inner side of the circular frame 8, and one end of each positioning wheel frame 9 is rotatably connected to a positioning wheel 10;

[0047] Through three circumferentially arranged positioning wheels 10, the hose wire can always move along the axis of the drum 3, so that the multiple grinding belts 6 can apply equal pressure to each position of the outer surface of the hose wire when rotating, thereby improving the uniformity of the surface texture of the hose wire.

[0048] Furthermore, two winding roller frames 11 are fixed at both ends of the upper side of the bottom plate 1, the upper end of the winding roller frame 11 at one end is rotatably connected to a wire winding roller 12, and a winding motor 13 for driving the wire winding roller 12 to rotate is installed on the outer side of the winding roller frame 11, and the upper end of the winding roller frame 11 at the other end is rotatably connected to a wire release roller 14;

[0049] During operation, the winding motor 13 drives the wire winding roller 12 to rotate, and the wire winding roller 12 rotates to pull the wire outside the wire release roller 14 toward the position of the wire winding roller 12, so that the wire passes through the inner side of the two rotating drums 3 at a uniform speed.

[0050] Working principle: Before use, the smooth hose wire is wound around the outside of the wire release roller 14, and then one end of the wire is passed through the inside of the two rotating drums 3 of the two grinding mechanisms, and then wound around the outside of the wire winding roller 12. During operation, the winding motor 13 drives the wire winding roller 12 to rotate, and the wire winding roller 12 rotates to pull the wire outside the wire release roller 14 toward the position of the wire winding roller 12, so that the wire passes through the inside of the two rotating drums 3 at a uniform speed;

[0051] When the device is running, the drive motor 101 of the drive mechanism runs to drive the driving bevel gear 105 to rotate. The driving bevel gear 105 drives the two driven bevel gears 106 to rotate in the opposite direction through tooth engagement. The two driven bevel gears 106 respectively drive the two rotating shafts 102 to rotate in the opposite direction. The two rotating shafts 102 respectively drive the two first rotating shaft pulleys 104 to rotate in the opposite direction. The two first rotating shaft pulleys 104 respectively drive the two drum pulleys 103 to rotate in the opposite direction through the belt. The two drum pulleys 103 respectively drive the two drums 3 of the two grinding mechanisms to rotate in the opposite direction;

[0052] When the drum 3 of the grinding mechanism rotates, it can drive the multiple columns 5 on its outer side to rotate, thereby driving each fork rod 7 to rotate around the outer side of the steel wire. Each fork rod 7 drives the internal abrasive belt 6 to rotate around the outer side of the steel wire. The multiple abrasive belts 6 are in contact with the outer surface of the steel wire. Therefore, when the multiple fork rods 7 and the multiple abrasive belts 6 rotate around the outer side of the steel wire, the surface of the abrasive belt 6 will generate friction with the surface of the steel wire, playing a role in grinding, thereby increasing the roughness of the steel wire surface;

[0053] The steel wire moves linearly along the inner side of the drum 3, and the multiple abrasive belts 6 in the grinding mechanism rotate around the outer side of the steel wire. Therefore, the abrasive belts 6 will grind spiral patterns on the surface of the steel wire. By driving the two drums 3 of the two grinding mechanisms to rotate in the opposite direction through the drive mechanism, the two drums 3 respectively drive the internal abrasive belts 6 to rotate around the outer side of the steel wire in the opposite direction, so that spiral patterns that cross each other can be ground on the surface of the steel wire, thereby improving the uniformity of the patterns on the steel wire surface, making the roughness of each position on the steel wire surface more uniform, and thus improving the processing quality of the steel wire;

[0054] While the rotating shaft 102 in the drive mechanism rotates, it can also drive the second rotating shaft pulley 202 of the reciprocating mechanism to rotate. The second rotating shaft pulley 202 drives the turntable pulley 201 to rotate through the belt. The turntable pulley 201 drives the runner 203 to rotate. The runner 203 drives the wavy chute 208 on its outer side to rotate. Since the multiple sliding pins 207 are all movably matched with the inner side of the wavy chute 208, when the wavy chute 208 rotates, it can drive the multiple sliding pins 207 to linearly reciprocate horizontally, thereby driving the multiple sliding rods 206 to reciprocate inside each slider 205 respectively, and further driving each fork rod 7 to reciprocate. Each fork rod 7 respectively drives each abrasive belt 6 to linearly reciprocate horizontally, so that the abrasive belt 6 can rotate around the outer side of the steel wire and at the same time can make a rapid reciprocating movement along the extension direction of the steel wire, thereby further improving the uniformity of the patterns on the steel wire surface and making the roughness of each position on the steel wire surface more uniform;

[0055] Since the diameter of the first rotating shaft pulley 104 is smaller than that of the drum pulley 103, and the diameter of the second rotating shaft pulley 202 is larger than that of the turntable pulley 201, when the rotating shaft 102 in the driving mechanism rotates, it can drive the drum pulley 103 to rotate at a slower speed, thereby driving the drum 3 to rotate at a slower speed. The rotating shaft 102 can drive the runner 203 of the reciprocating mechanism to rotate at a faster speed, thereby increasing the reciprocating movement frequency of the fork rod 7 and the abrasive belt 6 and improving the grinding efficiency of the hose steel wire;

[0056] The drum 3 of the grinding mechanism drives a plurality of fork rods 7 to rotate around the outside of the steel wire. When each fork rod 7 approaches the position of the friction plate 308 after each rotation, since the width of the friction plate 308 is greater than the width of the friction wheel 307, the friction wheel 307 can still contact the friction plate 308 when it reciprocates horizontally. Therefore, when the friction wheel 307 approaches the friction plate 308, the friction wheel 307 of the winding mechanism will contact the outside of the friction plate 308. Through the friction force between the two, the friction wheel 307 can be driven to rotate a certain angle. The friction wheel 307 drives the abrasive belt take-up roller 301 to rotate a certain angle. Since the abrasive belt 6 is wound around the outside of the abrasive belt take-up roller 301 and the abrasive belt release roller 302, when the abrasive belt take-up roller 301 rotates, it can apply a traction force to the abrasive belt 6, so that a section of the abrasive belt 6 is released from the outside of the abrasive belt release roller 302. A section of the abrasive belt 6 released from the outside of the abrasive belt release roller 302 will slide a certain distance along the outside of the abrasive belt support rod 303 and then be wound around the outside of the abrasive belt take-up roller 301. At the same time, under the action of the one-way locking mechanism, the torsion spring 306 applies a certain torsional moment to the pawl 305, so that the end of the pawl 305 presses against the outside of the ratchet wheel 304, so that the pawl 305 and the ratchet wheel 304 are engaged with each other. The engagement between the pawl 305 and the ratchet wheel 304 can prevent the abrasive belt take-up roller 301 from rotating in the reverse direction, so that the abrasive belt take-up roller 301 stops after rotating a certain angle each time and will not rotate back. Therefore, as the drum 3 drives a plurality of fork rods 7 and a plurality of abrasive belts 6 to rotate continuously, each rotation of the drum 3 can wind a section of the abrasive belt 6 on the outside of the abrasive belt release roller 302 onto the outside of the abrasive belt take-up roller 301, wind the abrasive belt 6 with a reduced roughness after grinding on the outside of the abrasive belt support rod 303 onto the outside of the abrasive belt take-up roller 301, and transfer the un-worn abrasive belt 6 on the outside of the abrasive belt release roller 302 to the outside of the abrasive belt support rod 303. Therefore, the position where the abrasive belt 6 contacts the steel wire always maintains a good roughness, so that the steel wire surface can be continuously ground well, further improving the uniformity of the surface texture of the steel wire after grinding and making the roughness of each position on the steel wire surface more uniform;

[0057] The clockwork spring 310 can apply a certain torsional torque to the sanding belt release roller 302, and the direction of the torsional torque is opposite to the rotation direction of the sanding belt release roller 302. Therefore, when the sanding belt 6 pulls the sanding belt release roller 302 to rotate, the sanding belt release roller 302 will be subjected to a certain reaction force, thereby applying a certain reverse pulling force to the sanding belt 6, so that the sanding belt 6 can be in a taut state, so that the sanding belt 6 can be tightly attached to the outer side of the sanding belt support rod 303, preventing the sanding belt 6 from sliding and deviating, so that the sanding belt 6 is more stable when grinding the steel wire surface, and the texture of the steel wire surface is more uniform.

Various modifications to these embodiments will be 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 present invention.
