DETAILED DESCRIPTION

[0042] Example embodiments will now be described more fully with reference to the accompanying drawings. However, example embodiments can be implemented in a variety of forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided to make the present invention more comprehensive and complete and to fully convey the concepts of example embodiments to those skilled in the art. The same reference numerals in the figures represent the same or similar structures, and thus their repeated description will be omitted.

[0043] The words expressing positions and directions described in the present invention are all explained with reference to the accompanying drawings as examples, but they can be changed as needed, and all such changes are included in the protection scope of the present invention.

[0044] Reference Figures 1A to 3 The present invention provides a fastener forming device 100, comprising: a wire guide device 1, a cutting device 2, a forming device 3, a pushing device 4 and a discharging device 5, and may further comprise a first supporting bracket 6 and a second supporting bracket 63. The wire guide device 1 feeds a workpiece (not shown) to be processed into the forming device 3, the cutting device 2 cuts the workpiece entering the forming device 3, the forming device 3 forms the cut workpiece into a fastener (not shown), the pushing device 4 pushes the fastener into the discharging device 5, and the discharging device 5 outputs the fasteners as a set number of groups.

[0045] Specifically, the wire guide device 1 includes a first cam assembly 10, and the first cam assembly 10 includes two first cams 101 that are relatively arranged and can rotate. The first cam 101 includes a first protrusion 1011, and the first protrusions 1011 of the two first cams 101 are used to drive the workpiece to be processed to move intermittently and control the length of the workpiece to be processed. The workpiece to be processed is, for example, a metal material such as high-carbon steel wire, iron wire, etc. In this embodiment, the workpiece to be processed is a high-carbon steel wire. The high-carbon steel wire has high strength and can withstand greater tension and pressure. The fasteners produced with high-carbon steel wire do not require a quenching process, that is, they can have high strength, which can ensure the strength of the fasteners, avoid environmental pollution caused by the fastener production process, shorten the production cycle, reduce production costs, and improve production efficiency. The high-carbon steel wire also has good wear resistance, easy processing, corrosion resistance and long life, which improves the quality of the fasteners and extends the service life of the fasteners.

[0046] The two first cams 101 preferably rotate synchronously, and the two first cams 101 are preferably symmetrically arranged relative to the moving direction of the workpiece to be processed, so that the two first protrusions 1011 can approach or move away from each other during the rotation of the two first cams 101. When the first protrusions 1011 of the two first cams 101 are close to each other, the gap (not shown) between the two first protrusions 1011 is less than or equal to the thickness of the workpiece to be processed, and the two first protrusions 1011 can clamp the workpiece to be processed, and the two first protrusions 1011 can drive the workpiece to be processed to move by rotating the two first cams 101. When the first protrusions 1011 of the two first cams 101 are far away from each other, the gap between the two first protrusions 1011 is greater than the thickness of the workpiece to be processed, and the two first protrusions 1011 cannot clamp the workpiece to be processed. Even if the two first cams 101 rotate, the two first protrusions 1011 cannot drive the workpiece to be processed to move.

[0047] The distance that the workpiece moves can be adjusted by adjusting the size of the first protrusion 1011 , or by adjusting the relative position between the two first cams 101 to adjust the size of the two first protrusions 1011 close to each other, thereby adjusting the distance that the workpiece moves.

[0048] The cutting device 2 includes a cutting blade 20, which is arranged at an angle relative to the axial direction of the workpiece to be processed. The cutting blade 20 is used to cut the workpiece to be processed conveyed by the wire guide device 1 and make the two ends of the cut workpiece have inclined surfaces. That is, the cutting blade 20 is arranged at an angle relative to the moving direction of the workpiece to be processed, so that after the workpiece to be processed is cut, the two ends of the workpiece to be processed have inclined surfaces, and the two ends of the workpiece to be processed form relatively sharp angles, so that there is no need to set up a special device to grind or sharpen the two ends of the workpiece to be processed, so that the fasteners produced can be more easily inserted into the parts to be fixed.

[0049] The cutting blade 20 is preferably made of special steel, so that the cutting blade 20 has high strength, ensuring that the cutting blade 20 can cut the workpiece to be processed, improving the yield rate of the fastener, and extending the service life of the cutting blade 20, avoiding the need to replace the cutting blade 20 due to damage and affecting the normal operation of the forming device 100. The angle at which the cutting blade 20 is inclined relative to the moving direction of the workpiece to be processed can be adjusted, so that the two ends of the workpiece to be processed can present sharp angles of different specifications.

[0050] The forming device 3 includes a fixing portion 31 and a forming portion 32. The fixing portion 31 is used to fix the workpiece to be processed to prevent the workpiece from shifting or falling and ensure the accuracy of the workpiece during molding. The forming portion 32 is used to mold the cut workpiece into a fastener.

[0051] The pushing device 4 includes a second cam 40 and a push rod 41. The second cam 40 is used to intermittently drive the push rod 41, and the push rod 41 is used to drive the fasteners to move and align. The second cam 40 has a second protrusion. When the second protrusion contacts the push rod 41, the push rod 41 drives the fasteners to move and align. The surface of the push rod 41 that can contact the second protrusion is preferably circular or arc-shaped, so that when the second protrusion contacts the push rod 41, the action of the push rod 41 driving the fasteners is relatively gentle, preventing the fasteners from being deformed or falling due to pressure.

[0052] The discharging device 5 includes a guide rail 50, a bonding component 51 and a segmentation component 52. The guide rail 50 is used to support fasteners. The bonding component 51 is, for example, a glue spraying component or a glue brushing component. The bonding component 51 is used to set a bonding layer for the aligned fasteners. The segmentation component 52 is used to divide the bonded fasteners into a group according to a set number. The bonding component 51 includes a glue barrel (not shown) and a glue barrel base 511. The glue barrel is installed on the glue barrel base 511. The glue barrel base 511 is installed on the second support frame 63. The guide rail 50 passes through the glue barrel base 511. The fastener moves toward the segmentation component 52 along the guide rail 50 through the glue barrel base 511 under the drive of the pushing device 4. When the fastener passes through the glue barrel base 511, an adhesive layer is set on the fastener, and the adhesive layer bonds the adjacent fasteners together. The number of adhesive components 51 can be one or more. Multiple adhesive components 51 can ensure that adjacent fasteners can be fully bonded to prevent adjacent fasteners from loosening.

[0053] In a specific embodiment, the molding device 100 may further include a first supporting bracket 6 , which includes a first platform 60 , a second platform 61 and a first supporting column 62 .

The two rollers 111 are disposed opposite to each other in the radial direction. The first drive device 112 is connected to one of the rollers 111 and drives the roller 111 to rotate, so that the workpiece to be processed with a circular radial cross section is extruded and deformed when passing between the two rollers 111. Of course, the radial cross section of the workpiece to be processed may also be other shapes. The two rollers 111 are circular as a whole, and the gap between the two rollers 111 is smaller than the radial size of the workpiece to be processed. When the workpiece to be processed passes between the two rollers 111, the workpiece to be processed is extruded and deformed. The degree of pressure deformation of the workpiece to be processed can be achieved by adjusting the gap between the two rollers 111.

[0055] The wire guide device 1 may further include a straightening assembly 12, which is disposed on the first platform 60 and is used to correct the straightness of the workpiece to be processed. The straightening assembly 12 is preferably disposed in front of the extrusion assembly 11, so that the workpiece to be processed is more easily corrected before being extruded, thereby improving the straightness of the workpiece to be processed.

[0056] The straightening assembly 12 may include a first straightening assembly 121 and a second straightening assembly 122, the first straightening assembly 121 includes a plurality of first straightening rollers 1211, the second straightening assembly 122 includes a plurality of second straightening rollers 1221, the first straightening rollers 1211 are used to correct the straightness of the workpiece to be processed in the up-down direction, and the second straightening rollers 1221 are used to correct the straightness of the workpiece to be processed in the left-right direction, or the first straightening rollers 1211 are used to correct the straightness of the workpiece to be processed in the left-right direction, and the second straightening rollers 1221 are used to correct the straightness of the workpiece to be processed in the up-down direction.

The straightening assembly 12 can correct the bent and deformed workpiece to be processed, thereby improving the quality and yield of the fastener.

[0057] The wire guide device 1 may also include a first guide bracket 13, a second guide bracket 14 and a third guide bracket 15 for guiding the movement of the workpiece to be processed. The first guide bracket 13 is arranged on the first platform 60, the second guide bracket 14 and the third guide bracket 15 are arranged on the second platform 61, and the second guide bracket 14 and the third guide bracket 15 are respectively arranged on both sides of the first cam assembly 10 along the moving direction of the workpiece to be processed. The first guide bracket 13 is used to support the workpiece to be processed to prevent the workpiece to be processed from being deformed or falling to the ground. A tensioning component (not shown) or other detection components (not shown) may be arranged on the first guide bracket 13, so that the first guide bracket 13 can control the length of the workpiece to be processed, which not only ensures that the workpiece to be processed can meet the subsequent production, but also controls the number of the workpiece to be processed entering the first guide bracket 13, and prevents deformation caused by too many workpieces to be processed. One or more perforations (not shown) may be arranged on the second guide bracket 14 and the third guide bracket 15 for the workpiece to be processed to pass through. The first guide bracket 13, the second guide bracket 14 and the third guide bracket 15 can control the direction of movement of the workpiece to be processed, and can also prevent the workpiece to be processed from being deformed during the movement.

[0058] The first cam assembly 10 may further include a cam bracket 102 and a spring 103. One of the two first cams 101 is movably disposed on the cam bracket 102 in a direction perpendicular to the movement of the workpiece to be processed. One end of the spring 103 is connected to the cam bracket 102, and the other end of the spring 103 is used to abut against the movably movable first cam 101 so that the first protrusions 1011 of the two first cams 101 clamp the workpiece to be processed. The spring 103 has a downward elastic force, which can push the first cam 101 located at the upper side toward the first cam 101 located at the lower side, so that the two first cams 101 have a certain clamping force on the workpiece to be processed, so as to ensure that the two first protrusions 1011 drive the workpiece to be processed to move.

[0059] When the first protrusions 1011 of the two first cams 101 approach and clamp the workpiece, the workpiece moves; when the first protrusions 1011 of the two first cams 101 move away from each other, the workpiece stops moving.
