Description

Technical Field

[0001] This invention relates to the field of wire drawing technology, and more particularly to a wire drawing processing device for the production of automotive fastener wires. Background Technology

[0002] In the automotive fastener manufacturing industry, wire drawing is one of the key processes. By gradually drawing the metal wire to the required thickness, the material strength, toughness, and surface quality can be optimized to meet the performance requirements of high-strength bolts, nuts, and other fasteners.

[0003] To ensure a smooth drawing process, the wire needs to be lubricated before entering the die. Currently, the industry commonly uses cavities filled with drawing powder to lubricate the wire. As a solid lubricant, drawing powder can significantly reduce the friction between the wire and the die, thereby reducing wear and extending the die's life.

[0004] In the initial stage of the wire drawing process, the wire needs to be passed through the drawing powder cavity. However, the cavity contains a large amount of drawing powder and is quite long, causing significant resistance to the wire as it passes through. Therefore, the workers empty the drawing powder from the cavity to ensure there are no obstructions before passing the wire through. However, the wire is not straight, and the bent portion may rub against the inner wall of the cavity, hindering the threading process. During this process, the workers need to continuously adjust the angle and position of the wire to ensure it can pass through the cavity smoothly. After the wire successfully passes through the cavity, the drawing powder is poured back in and evenly distributed. Only after these operations are completed can the wire officially enter the mold for drawing. The initial stage is highly complex and time-consuming, resulting in low production efficiency. Summary of the Invention

[0005] In view of this, the present invention provides a drawing processing device for automotive fastener wire production, which can overcome the disadvantages of the high complexity and long time required in the initial stage of operation, which is due to the need for workers to constantly adjust the angle and position of the wire to ensure that the wire can pass smoothly through the cavity, and then pour drawing powder into the cavity after the wire has successfully passed through the cavity, resulting in low production efficiency.

[0006] The technical solution of this invention is as follows: a drawing processing device for automotive fastener wire production, comprising a frame, support plates, U-shaped plates, placement plates, drawing dies, arc plates, rotating tubes, powder boxes, caps, guide tubes, a rotating mechanism, a guiding mechanism, and a conveying mechanism. Support plates are connected to the left and right sides of the top of the frame. A U-shaped plate is connected to the left support plate, and a placement plate is connected inside the U-shaped plate. A drawing die is placed on the placement plate. An arc plate is connected to the top of the U-shaped plate and is connected to the drawing die. Rotating tubes are rotatably connected to the support plates. A powder box for holding drawing powder is connected between two rotating tubes. Caps are provided on both the upper and lower sides of the powder box. Guide tubes are rotatably connected inside the rotating tubes and communicate with the inside of the powder box. The rotating mechanism is used to control the rotation of the powder box to complete the turning of the powder box, so that the drawing powder in the powder box falls below the guide tube without the need to pour out the drawing powder. The conveying mechanism is used to convey the wire into the powder box, and the guiding mechanism is used to guide the wire in the powder box.

[0007] Furthermore, the rotating mechanism includes a mounting plate, a gearbox, a drive cam, a drive shaft, an intermittent wheel, and a drive assembly. The mounting plate is connected to the support plate on the right side, and the gearbox is mounted on the bottom of the mounting plate. The output shaft of the gearbox is connected to the drive cam, and the drive shaft is connected to the drive cam. The intermittent wheel is connected to the rotating tube on the right side, and the drive shaft is located inside the intermittent wheel. The drive cam and the intermittent wheel are in contact. The drive assembly is used to drive the intermittent wheel to rotate, and the intermittent wheel drives the powder box to rotate.

[0008] Furthermore, the drive assembly includes a guide frame, a slide plate, a lead screw motor, a spur rack, and a spur gear. Two guide frames are connected to each support plate, and a slide plate is slidably connected to both guide frames on the same support plate. A lead screw motor is mounted on each guide frame, and the lead screw of the lead screw motor is rotatably connected to the support plate. The lead screw of the lead screw motor and the slide plate are connected by threads. A spur rack is connected to the slide plate on the right side, and a spur gear is connected to the input shaft of the gearbox. The spur gear and the spur rack mesh.

[0009] Furthermore, the guiding mechanism includes a slide rod, a contact plate, a spring, a semi-circular plate, and a pushing assembly. Slide rods are slidably connected to both the front and rear sides of the toner box, and contact plates and semi-circular plates are connected to the slide rods. The contact plates are located outside the toner box, and the semi-circular plates are located inside the toner box. A spring connects the toner box and the contact plates. The pushing assembly is used to push the contact plates, causing the semi-circular plates to move. The two semi-circular plates contact each other to form a guiding channel for guiding the wires inside the toner box.

[0010] Furthermore, the pushing component includes a connecting plate and an inclined plate. Two connecting plates are connected to each slide plate, and inclined plates are connected to each connecting plate. The inclined plates are used to push the contact plate, causing the semicircular plate to move. The two semicircular plates come into contact with each other to form a guide channel for guiding the wire in the powder box.

[0011] Furthermore, the conveying mechanism includes a guide plate, a slider, an electric conveying wheel, and a bidirectional lead screw. The top of the mounting plate is connected to the guide plate, which has a guide opening. Sliders are slidably connected to the upper and lower sides inside the guide opening. Each slider is equipped with an electric conveying wheel for conveying the wire to the powder box. A bidirectional lead screw is rotatably connected to the guide plate, and the bidirectional lead screw and the slider are connected by threads.

[0012] Furthermore, it also includes a collection box and a magnet. The collection box is slidably connected to the support plate on the left side. There is an opening at the bottom of the U-shaped plate. The residual wire drawing powder on the wire falls into the collection box through the opening on the U-shaped plate. The collection box is connected to a magnet, which is attracted to the bottom of the U-shaped plate.

[0013] Furthermore, it also includes telescopic tubes, with telescopic tubes fitted onto the slide rods, and the two ends of the telescopic tubes being connected to the powder box and the semi-circular plate, respectively.

[0014] Compared with the prior art, the present invention has the following advantages:

[0015] 1. This invention uses a lead screw motor to drive the powder box to rotate, turning the powder box so that the drawing powder inside the powder box falls below the guide tube. There is no need to pour out the drawing powder. The guide channel formed by the semi-circular plate can guide the wire, preventing the wire from sagging and ensuring that the wire can pass smoothly through the powder box. Moreover, there is no need for the operator to adjust the angle and position of the wire, reducing the complexity of operation and thus improving production efficiency.

[0016] 2. The collection box can collect the residual wire drawing powder, which can be recycled and reused, saving resources. Attached Figure Description

A powder box 8 is connected between the two rotating tubes 7. The powder box 8 is equipped with a cover 9 on both the upper and lower sides. A guide tube 10 is rotatably connected inside the rotating tube 7. The guide tube 10 communicates with the inside of the powder box 8. The rotating mechanism is used to control the rotation of the powder box 8. The conveying mechanism is used to convey the wire into the powder box 8. The guiding mechanism is used to guide the wire in the powder box 8.

[0033] Reference Figures 4-6 The rotating mechanism includes a mounting plate 111, a gearbox 112, a drive cam 113, a drive shaft 114, an intermittent wheel 115, and a drive assembly. The upper right side of the support plate 2 is bolted to the mounting plate 111. The gearbox 112 is bolted to the bottom of the mounting plate 111. The output shaft of the gearbox 112 is connected to the drive cam 113. The upper right side of the drive cam 113 is connected to the drive shaft 114. The intermittent wheel 115 is connected to the rotating tube 7 on the right side. The drive shaft 114 is located inside the intermittent wheel 115. The drive cam 113 and the intermittent wheel 115 are in contact. The drive assembly is used to drive the intermittent wheel 115 to rotate. The intermittent wheel 115 drives the powder box 8 to rotate.

[0034] Reference Figures 4-6 The drive assembly includes a guide frame 116, a slide plate 117, a lead screw motor 118, a rack and pinion 119, and a spur gear 1110. Two guide frames 116 are bolted to the opposite sides of the two support plates 2. The two guide frames 116 on the same support plate 2 are arranged in a front-to-back configuration. The slide plate 117 is slidably connected to both guide frames 116 on the same support plate 2. The lead screw motor 118 is bolted to each guide frame 116. The lead screw of the lead screw motor 118 is rotatably connected to the support plate 2. The lead screw of the lead screw motor 118 is threaded to the slide plate 117. The lower left side of the right slide plate 117 is bolted to the rack and pinion 119. The input shaft of the gearbox 112 is keyed to the spur gear 1110, which meshes with the rack and pinion 119.

[0035] Reference Figure 7 and Figure 8The guiding mechanism includes a slide rod 121, a contact plate 122, a spring 123, a semi-circular plate 124, and a pushing assembly. A set of slide rods 121 is slidably connected to both the front and rear sides of the lower part of the toner box 8. Each set has three slide rods 121, which are evenly spaced. The three slide rods 121 in the same set are connected to a contact plate 122, which is located outside the toner box 8. A spring 123 is fitted on each slide rod 121, and the two ends of the spring 123 are connected to the toner box 8 and the contact plate 122, respectively. The three slide rods 121 in the same set are connected to a semi-circular plate 124, which is located inside the toner box 8. The semi-circular plate 124 is at the same height as the guide tube 10. The pushing assembly is used to push the contact plate 122, causing the semi-circular plate 124 to move. The two semi-circular plates 124 come into contact with each other, forming a guiding channel for guiding the wires inside the toner box 8.

[0036] Reference Figure 7 and Figure 8 The pushing component includes a connecting plate 125 and an inclined plate 126. Two connecting plates 125 are connected to the side of the slide plate 117 facing the powder box 8. The two connecting plates 125 on the same slide plate 117 are arranged opposite each other. An inclined plate 126 is connected to the side of the connecting plate 125 facing the powder box 8.

[0037] Reference Figure 9 and Figure 10 The conveying mechanism includes a guide plate 131, a slider 133, an electric conveying wheel 134, and a bidirectional lead screw 135. The top of the mounting plate 111 is bolted to the guide plate 131. Guide openings 132 are formed on both the left and right sides of the guide plate 131. Sliders 133 are slidably connected to the upper and lower sides of the guide openings 132. Electric conveying wheels 134 are mounted on the sliders 133. Bidirectional lead screws 135 are rotatably connected to the left and right sides of the rear side of the guide plate 131. The bidirectional lead screw 135 and the sliders 133 are connected by threads. The upper end of the bidirectional lead screw 135 has… The knob can be used to rotate the bidirectional lead screw 135. The threads on the two sliders 133 inside the same guide opening 132 are in opposite directions, so the bidirectional lead screw 135 can drive the two sliders 133 to move in opposite directions. Rotating the bidirectional lead screw 135 can drive the two sliders 133 to move, and the sliders 133 can drive the two electric conveyor wheels 134 to move. Adjusting the distance between the two electric conveyor wheels 134 can be adjusted according to the thickness of the wire to accommodate wires of different thicknesses.

[0038] The operator opens the cover 9, pours the drawing powder into the powder box 8, closes the cover 9, and then controls the lead screw motor 118 to move the slide plate 117 closer to the powder box 8. The right slide plate 117 drives the rack 119 to move to the left, and the rack 119 drives the spur gear 1110 to rotate. The spur gear 1110 drives the drive cam 113 and drive shaft 114 to rotate through the gearbox 112. After the drive cam 113 disengages from the intermittent wheel 115, the drive shaft 114 rotates into the intermittent wheel 115 and drives the intermittent wheel 115 to rotate. When the drive shaft 114 rotates out of the intermittent wheel 115, the drive cam 113 re-engages with the intermittent wheel 115, and the intermittent wheel 115 stops rotating. At this time, the intermittent wheel 115 is just turning. The drive cam 113 moves 90 degrees and can limit the intermittent wheel 115, preventing it from rotating. The drive cam 113 and drive shaft 114 continue to rotate. After the drive cam 113 disengages from the intermittent wheel 115, the drive shaft 114 rotates into the intermittent wheel 115 and drives it to rotate. When the drive shaft 114 rotates out of the intermittent wheel 115, the drive cam 113 re-engages with the intermittent wheel 115, and the intermittent wheel 115 stops rotating. At this point, the intermittent wheel 115 has rotated exactly 90 degrees, and the powder box 8 has rotated a total of 180 degrees, completing the rotation of the powder box 8. This allows the drawing powder inside the powder box 8 to fall below the guide tube 10, eliminating the need to empty the powder. Then, the spur rack 119 and spur gear 1110 disengage. When disengaged, the spur gear 1110 stops rotating, and the slide plate 117 continues to move, causing the inclined plate 126 to continue moving closer to the powder box 8. The inclined plate 126 will contact the contact plate 122 and push the contact plate 122, causing the two contact plates 122 to move closer to each other. The spring 123 is compressed, and the contact plate 122 drives the two semicircular plates 124 to move closer to each other. The two semicircular plates 124 contact each other, forming a guide channel. Then, the worker passes the wire through the upper and lower electric conveyor wheels 134. The electric conveyor wheels 134 convey the wire to the left. The wire passes through the guide tube 10 on the right and extends into the powder box 8. The wire will enter the guide channel, which guides the wire to prevent it from sagging and ensures that the wire can pass smoothly. The wire passes through powder box 8 without requiring operator adjustment of its angle and position, reducing operational complexity and improving production efficiency. It then passes through left guide tube 10 and exits powder box 8. Finally, the wire passes through drawing die 5. The operator then controls screw motor 118 to move slide plate 117 away from powder box 8. Slide plate 117 on the right moves rack 119 to the right, which in turn drives spur gear 1110 to rotate in the opposite direction. Spur gear 1110, through gearbox 112, drives drive cam 113 and drive shaft 114 to rotate in the opposite direction. Drive shaft 114 rotates powder box 8 180 degrees in the opposite direction, resetting powder box 8 so that the drawing powder inside is aligned with guide tube 10. Slide plate 117 then continues moving.As the inclined plate 126 continues to move away from the powder box 8, it will disengage from the contact plate 122. Under the action of the spring 123, the two contact plates 122 move away from each other, and the two semicircular plates 124 move away from each other accordingly, disengaging from each other. The drawing powder will then come into contact with the wire, lubricating it. At this point, the electric conveyor wheel 134 continues to convey the wire to the left. Then, a pulling device is installed on the left side of the frame 1 to pull the wire to the left, allowing the drawing die 5 to draw the wire.

[0039] Reference Figure 11 and Figure 12 It also includes a collection box 141 and a magnet 142. The collection box 141 is slidably connected to the upper left side of the support plate 2 on the left side. The bottom right side of the U-shaped plate 3 has an opening (not shown in the figure). The magnet 142 is connected to the upper left side of the collection box 141. The bottom of the U-shaped plate 3 is made of iron, so the magnet 142 can be attracted to the bottom of the U-shaped plate 3.

[0040] When the wire is removed from the powder box 8, the residual drawing powder on the wire falls into the collection box 141 through the opening on the U-shaped plate 3 for collection. It can be recycled later, saving resources. The magnet 142 is attracted to the bottom of the U-shaped plate 3 to prevent the collection box 141 from sliding down. After the collection box 141 is full of drawing powder, the collection box 141 is pulled down, and the magnet 142 and the U-shaped plate 3 are separated. Then the drawing powder in the collection box 141 is processed.

[0041] Reference Figure 8 It also includes a telescopic tube 15. The telescopic tube 15 is sleeved on the slide rod 121. The two ends of the telescopic tube 15 are connected to the powder box 8 and the semi-circular plate 124 respectively.

[0042] The telescopic tube 15 can block the drawing powder, preventing it from falling into the gap between the slide rod 121 and the powder box 8, ensuring that the slide rod 121 can slide normally. When the semicircular plate 124 moves, the telescopic tube 15 will extend and retract accordingly to ensure that the semicircular plate 124 can move normally.

[0043] Obviously, the embodiments described above are only some embodiments of the present invention, and not all embodiments. They only express the preferred implementation of the present invention and are described in a relatively specific and detailed manner, but should not be construed as limiting the scope of the present invention.

[0044] It should be noted that, for those skilled in the art, various modifications, additions or subtractions, improvements and substitutions can be made without departing from the concept of the present invention. Therefore, 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.
