Description

Technical Field

[0001] The invention relates to the technical field of steel wire screw sleeve forming, in particular to an automatic steel wire screw sleeve forming device. Background Art

[0002] Wire thread inserts are inserts developed to protect threaded holes of non-ferrous metals and are suitable for threaded connections. They are screwed into and fastened in the threaded hole of one of the connected parts to form a standard internal thread, and the bolt (or screw) is then screwed into it. The cold-rolled stainless steel wire is made into a spiral inner and outer concentric thread coil, and the cross section is diamond-shaped, with high hardness and good surface roughness. Since the wire thread insert is made of stainless steel material, it has high hardness, which increases the life of the softer base thread by dozens to hundreds of times; increases its strength, and avoids the occurrence of stripping and random buckling, while increasing the connection strength and acceptance surface; and the characteristics of the wire thread insert material itself and its extremely smooth surface, when used in harsh environments such as humidity and corrosion, it will not cause the mating base to rust, avoiding the loss of replacing the expensive base due to the rust of the threaded hole and the inability to disassemble, and can be used in chemical, aviation, military equipment and other occasions that require a high insurance factor.

[0003] In the existing wire screw sleeve forming device, the wire is pushed from the back to the front into the middle of the gap below the winding roller by the wire feeding mechanism. However, in order to improve the accuracy of the wire entering the gap, it is generally necessary to set the width and length of the gap slightly larger, and in order to facilitate the subsequent discharge of the wire screw sleeve, the bottom of the gap is not blocked. When the winding roller is rotated and extended downward in this state to process the wire screw sleeve, the front end of the wire will be affected by the rotation and deviate to one side of the gap. In the subsequent winding process of the thinner diameter wire, the gradually wound and formed screw sleeve will have a certain tensile force downward under the action of its own gravity, thereby causing a certain distance between the upper and lower circles of the wire, or expanding outward due to the plasticity of the thinner wire, so that the inner wall of the wound wire screw sleeve is not in contact with the outer wall of the winding roller, thereby affecting the quality of the wire screw sleeve wound by the thinner diameter wire.

DETAILED DESCRIPTION

[0024] 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.

[0025] See also Figure 1-Figure 6 , an embodiment provided by the present invention:

[0026] A wire screw insert automatic forming device comprises a workbench 1, a rotating component 2 is fixedly installed on the front side of the workbench 1 by screws, the structure of the rotating component 2 comprises a square block 3, an adjusting component 4 is fixedly installed on the bottom of the square block 3, a first arc block 5 and a second arc block 6 are fixedly installed on the bottom of the adjusting component 4, and the first arc block 5 and the second arc block 6 are coaxial with the adjusting component 4 and have the same diameter, and the back corner of the second arc block 6 is arc-shaped, a wire feeding mechanism 7 is fixedly installed below the rotating component 2 on the front side of the workbench 1, a cantilever plate 8 is fixedly installed below the wire feeding mechanism 7 on the front side of the workbench 1, a sleeve seat 9 is fixedly installed on the front side of the cantilever plate 8, and a T-shaped disc 10 is rotatably connected to the sleeve seat 9. A multi-section electric push rod 11 fixedly installed on the top of the T-shaped disc 10 is electrically connected to the rotating component 2 and the adjusting component 4, and a limit block 12 is fixedly installed on the telescopic end of the multi-section electric push rod 11, and the width of the limit block 12 is less than the spacing between the first arc block 5 and the second arc block 6.

[0027] The steel wire is pushed from the back to the front by the wire feeding mechanism 7, so that the front end of the steel wire extends into the gap between the first arc block 5 and the second arc block 6, and the top of the steel wire is located at the top position of the gap by operating the adjusting mechanism 4, and then the multi-section electric push rod 11 is operated to push it upward by a set amount, so as to drive the limit block 12 to move upward, so that the limit block 12 squeezes the front end of the steel wire in the gap between the first arc block 5 and the second arc block 6, and limits its front end to the bottom of the adjusting component 4, thereby achieving the purpose of limiting the front end of the steel wire and effectively avoiding the situation of falling down during the forming process of the wire screw sleeve, wherein the rotating component 2 and the adjusting component 4 are used in combination according to the set operating procedure, so that the steel wire sent forward from the wire feeding mechanism 7 can be wound and formed;

[0028] In the subsequent process of winding the steel wire, the multi-section electric push rod 11 shrinks downward at the same rate as the downward advancement of the adjusting component 4, so that the top of the limit block 12 can always be pressed on the front end of the steel wire, and in the process of winding the steel wire by running the rotating component 2 to drive the adjusting component 4 and the first arc block 5 and the second arc block 6 to rotate together, since the limit block 12 is between the first arc block 5 and the second arc block 6, the limit block 12 can drive the multi-section electric push rod 11 to rotate with the first arc block 5 and the second arc block 6, and the T-shaped disc 10 rotates along the inside of the sleeve seat 9; after a single wire screw sleeve is wound and cut, the multi-section electric push rod 11 quickly returns to its initial state downward, and the adjusting component 4 also returns to its original state upward, so that a larger gap is formed between the two, providing sufficient space for the formed wire screw sleeve to fall down.

[0029] The top of the cantilever plate 8 is fixedly mounted with an upright vertical plate 13 , the front of the upright vertical plate 13 is fixedly mounted with an inclined plate 14 , a through slot 15 is provided on the top of the inclined plate 14 , and the upright vertical plate 13 is sleeved on the outer surface of the multi-section electric push rod 11 through the through slot 15 .

[0030] After a single wire screw sleeve is wound and cut, when the multi-section electric push rod 11 quickly returns to its original state, the position of the limit block 12 is slightly lower than the height position of the through groove 15 on the inclined plate 14, and the inclined plate 14 is inclined downward from back to front. Therefore, the wire screw sleeve wound on the adjustment component 4 will be blocked by the inclined plate 14 when falling downward, and then slide down along the upper surface of the inclined plate 14 to transfer the formed wire screw sleeve, effectively avoiding the wire screw sleeve from being set on the outer surface of the multi-section electric push rod 11 and affecting the operation of subsequent devices.

[0031] An integrated plate 16 is fixedly installed on one side of the wire feeding mechanism 7 on the front side of the workbench 1, an electric telescopic rod 17 is fixedly installed on one side of the integrated plate 16, a cutting assembly 18 is fixedly installed on the telescopic end of the electric telescopic rod 17, and the cutting assembly 18 is located on one side between the wire feeding mechanism 7 and the second arc block 6, the structure of the cutting assembly 18 includes a threaded column 19, the outer surface of the threaded column 19 is threadedly sleeved with a connecting sleeve 20, a U-shaped frame 21 is fixedly installed on the side of the connecting sleeve 20 away from the electric telescopic rod 17, a driving motor 22 is installed on the front side of the U-shaped frame 21, a cutting blade 23 is fixedly sleeved on the output end of the driving motor 22, and the cutting blade 23 is located inside the U-shaped frame 21.

[0032] When the steel wire is wound into a wire screw sleeve, the electric telescopic rod 17 is operated to extend outward accordingly, driving the cutting assembly 18 to move between the wire screw sleeve and the wire feeding mechanism 7, so that the cutting blade 23 contacts the steel wire between the two. In addition, by cooperating with the operation of the driving motor 22, it drives the cutting blade 23 to cut the steel wire at the front end of the wire feeding mechanism 7, so as to timely separate the formed wire screw sleeve and the steel wire. At the same time, since the threaded column 19 and the connecting sleeve 20 are in the form of a threaded combination, the two are detachable, and then it is convenient to disassemble and assemble the whole composed of the driving motor 22, the cutting blade 23, the U-shaped frame 21 and the connecting sleeve 20.

[0033] The structure of the adjustment component 4 includes a hydraulic cylinder 24, a locking sleeve 25 is fixedly installed at the telescopic end of the hydraulic cylinder 24, the bottom of the winding roller 26 installed in the locking sleeve 25 is fixedly connected to the top of the first arc block 5 and the second arc block 6, and the fastening nail threaded on the front of the locking sleeve 25 passes through the inside of the winding roller 26. The structure of the rotating component 2 also includes a protective box 27, the protective box 27 is fixedly installed on the front of the workbench 1, a servo motor 28 is installed on the top of the protective box 27, the output end of the servo motor 28 is fixedly connected to the transmission shaft 29, the outer surface of the transmission shaft 29 is fixedly sleeved with the first spur gear 30, the top wall of the protective box 27 is fixedly installed with a limiting sleeve, the bottom of the rotating shaft 31 rotatably installed inside the limiting sleeve is fixedly connected to the top of the square block 3, the second spur gear 32 fixedly sleeved on the outer surface of the rotating shaft 31 is connected to the first spur gear 30 through a tooth groove matching, the bottom of the workbench 1 is fixedly installed with a base 33, and a plurality of supporting columns 34 fixedly installed at the bottom of the base 33 are evenly arranged.

[0034] When the front end of the steel wire is pressed against the bottom of the winding roller 26 by using the multi-section electric push rod 11 and the limit block 12, the servo motor 28 is then operated to drive the transmission shaft 29 to rotate in the set direction, thereby driving the first spur gear 30 to rotate, and then the second spur gear 32 connected to the first spur gear 30 through the tooth groove drives the rotating shaft 31 to rotate together, thereby causing the square block 3 to drive the adjusting component 4 to rotate synchronously, and in addition, the hydraulic cylinder 24 is operated according to the wire feeding rate of the wire feeding mechanism 7, so that it extends downward accordingly, driving the locking sleeve 25 and the winding roller 26 to move downward at the set rate, so as to achieve the purpose of winding the steel wire sent out from the wire feeding mechanism 7.

[0035] Working principle: by running the wire feeding mechanism 7, the front end of the steel wire is fed into the gap between the first arc block 5 and the second arc block 6, and the multi-section electric push rod 11 is operated to cause it to push upward by a set amount, so as to drive the limit block 12 to move upward, so that the limit block 12 squeezes the front end of the steel wire in the gap between the first arc block 5 and the second arc block 6, and limits its front end to the bottom of the adjustment component 4, and at the same time, the servo motor 28 is operated to cause it to drive the transmission shaft 29 to rotate in the set direction, thereby driving the first spur gear 30 to rotate, and then the second spur gear 32 connected to the first spur gear 30 through the tooth groove drives the rotating shaft 31 to rotate together, and then causes the square block 3 to drive the adjustment component 4 to rotate synchronously, and in addition, the hydraulic cylinder 24 is operated according to the wire feeding rate of the wire feeding mechanism 7, so that it performs a downward extension operation accordingly, driving the locking sleeve 25 and the winding roller 26 to move downward at a set rate. The multi-section electric push rod 11 also contracts downward at the same rate as the hydraulic cylinder 24 pushes downward, so that the limit block 12 always keeps the front end of the steel wire for making the wire screw sleeve pressed against the bottom of the winding roller 26, and because the limit block 12 is between the first arc block 5 and the second arc block 6, the limit block 12 can drive the multi-section electric push rod 11 to rotate with the first arc block 5 and the second arc block 6, and at the same time, the T-shaped disc 10 follows the internal rotation along the sleeve seat 9 to avoid hindering the winding of the steel wire. When the steel wire is wound into the wire screw sleeve, the electric telescopic rod 17 is extended outward to drive the cutting assembly 18 to move between the wire screw sleeve and the wire feeding mechanism 7, so that the cutting blade 23 contacts the steel wire between the two. In addition, by cooperating with the operation of the drive motor 22, it is prompted to drive the cutting blade 23 to cut the steel wire at the front end of the wire feeding mechanism 7, so as to timely separate the formed wire screw sleeve and the steel wire.
