Description

Technical Field

[0001] The present invention relates to the technical field of wire drawing, and particularly to a wire drawing treatment device for the production of automotive fastener wires. Background Art

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

[0003] To ensure the smooth progress of the wire drawing process, the wire needs to be lubricated before entering the die. Currently, in the industry, a cavity filled with wire drawing powder is generally used to lubricate the wire. As a solid lubricant, the wire drawing powder can significantly reduce the friction between the wire and the die, thereby reducing wear and extending the die life.

[0004] In the initial stage of the wire drawing process, the wire needs to pass through the cavity filled with wire drawing powder. However, there is a large amount of wire drawing powder in the cavity, and the cavity is relatively long. When the wire passes through the cavity, it will encounter a large resistance. Therefore, the staff will empty the wire drawing powder in the cavity to ensure that there are no obstacles inside the cavity, and then pass the wire through the cavity. However, the wire is not in a straight state, and the bent part of the wire may rub against the inner wall of the cavity, resulting in the obstruction of the wire threading process. During this process, the staff needs to continuously adjust the angle and position of the wire to ensure that the wire can pass through the cavity smoothly. After the wire successfully passes through the cavity, the wire drawing powder is poured into the cavity and ensured to be evenly filled. After completing the above operations, the wire can officially enter the die for wire drawing treatment. The operation complexity in the initial stage is relatively high and takes a long time, resulting in low production efficiency. Summary of the Invention

[0005] In view of this, the present invention provides a wire drawing treatment device for the production of automotive fastener wires, which can overcome the disadvantages that the staff needs to continuously adjust the angle and position of the wire to ensure that the wire can pass through the cavity smoothly, and after the wire successfully passes through the cavity, the wire drawing powder is poured into the cavity. The operation complexity in the initial stage is relatively high and takes a long time, resulting in low production efficiency.

At the inner bottom of the U-shaped plate 3, a placement plate 4 is bolted. A drawing die 5 is placed on the placement plate 4. At the top of the U-shaped plate 3, an arc-shaped plate 6 is bolted. The arc-shaped plate 6 and the drawing die 5 are bolted together, and the drawing die 5 can be disassembled and replaced. In the middle of the upper part of the support plates 2, rotating tubes 7 are rotatably connected. A powder box 8 is connected between the two rotating tubes 7. Covers 9 are provided on both the upper and lower sides of the powder box 8. In the rotating tubes 7, guiding tubes 10 are rotatably connected. The guiding tubes 10 communicate 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, and the guiding mechanism is used to guide the wire in the powder box 8.

[0032] Referring to Figures 4-6 , the rotating mechanism includes a mounting plate 111, a gear box 112, a driving cam 113, a driving shaft 114, an intermittent wheel 115 and a driving component. On the upper right side of the right support plate 2, a mounting plate 111 is bolted. At the bottom of the mounting plate 111, a gear box 112 is bolted. A driving cam 113 is connected to the output shaft of the gear box 112. On the upper right side of the driving cam 113, a driving shaft 114 is connected. An intermittent wheel 115 is connected to the right rotating tube 7. The driving shaft 114 is located inside the intermittent wheel 115, and the driving cam 113 contacts the intermittent wheel 115. The driving component is used to drive the intermittent wheel 115 to rotate, and the intermittent wheel 115 drives the powder box 8 to rotate.

[0033] Referring to Figures 4-6 , the driving component includes a guiding frame 116, a sliding plate 117, a screw motor 118, a straight rack 119 and a straight gear 1110. On the mutually distant sides of the two support plates 2, two guiding frames 116 are bolted. The two guiding frames 116 on the same support plate 2 are arranged front and back relatively. A sliding plate 117 is slidably connected to the two guiding frames 116 on the same support plate 2. Screw motors 118 are bolted to the guiding frames 116. The screws of the screw motors 118 are rotatably connected to the support plates 2, and the screws of the screw motors 118 are threadedly connected to the sliding plate 117. On the lower left side of the right sliding plate 117, a straight rack 119 is bolted. A straight gear 1110 is key-connected to the input shaft of the gear box 112, and the straight gear 1110 meshes with the straight rack 119.

[0034] Referring to Figure 7 and Figure 8, the guiding mechanism includes a sliding rod 121, a contact plate 122, a spring 123, a semi-circular plate 124 and a pushing component. On the front and rear sides of the lower part of the powder box 8, a group of sliding rods 121 are slidably connected. Each group has three sliding rods 121, and the three sliding rods 121 in each group are evenly spaced. A contact plate 122 is commonly connected to the three sliding rods 121 in the same group. The contact plate 122 is located outside the powder box 8. Springs 123 are sleeved on the sliding rods 121, and the two ends of the springs 123 are respectively connected to the powder box 8 and the contact plate 122. A semi-circular plate 124 is commonly connected to the three sliding rods 121 in the same group. The semi-circular plate 124 is located inside the powder box 8, and the semi-circular plate 124 and the guiding tube 10 are at the same height. The pushing component is used to push the contact plate 122 so that the semi-circular plate 124 moves, and the two semi-circular plates 124 are in contact with each other to form a guiding channel for guiding the wire in the powder box 8.

[0035] Refer to Figure 7 and Figure 8 , the pushing component includes a connecting plate 125 and an inclined plate 126. On the side of the sliding plate 117 facing the powder box 8, two connecting plates 125 are respectively connected. The two connecting plates 125 on the same sliding plate 117 are arranged front and back relatively. On the side of the connecting plate 125 facing the powder box 8, inclined plates 126 are respectively connected.

[0036] Refer to Figure 9 and Figure 10 , the conveying mechanism includes a guiding 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 with a guiding plate 131. Guiding openings 132 are opened on the left and right sides of the guiding plate 131. The upper and lower sides inside the guiding openings 132 are slidably connected with sliders 133. Electric conveying wheels 134 are respectively installed on the sliders 133. The left and right sides at the rear of the guiding plate 131 are respectively rotatably connected with bidirectional lead screws 135. The bidirectional lead screws 135 and the sliders 133 are threadedly connected. There is a knob at the upper end of the bidirectional lead screw 135, and the bidirectional lead screw 135 can be rotated through the knob. The thread directions of the two sliders 133 in the same guiding opening 132 are opposite, so the bidirectional lead screw 135 can drive the two sliders 133 to move in opposite directions. By rotating the bidirectional lead screw 135, the two sliders 133 can be driven to move. The sliders 133 can drive the two electric conveying wheels 134 to move. The distance between the two electric conveying wheels 134 can be adjusted according to the thickness of the wire to adapt to wires of different thicknesses.

[0037] The staff member opens the cover 9, then pours the wire drawing powder into the powder box 8, closes the cover 9, and then controls the lead screw motor 118 to drive the slide plate 117 to move towards the powder box 8. The slide plate 117 on the right drives the straight rack 119 to move leftward. The straight rack 119 drives the straight gear 1110 to rotate. The straight gear 1110 drives the driving cam 113 and the driving shaft 114 to rotate through the gear box 112. After the driving cam 113 and the intermittent wheel 115 are disengaged, the driving shaft 114 will rotate into the intermittent wheel 115 and drive the intermittent wheel 115 to rotate. When the driving shaft 114 rotates out of the intermittent wheel 115, the driving cam 113 contacts the intermittent wheel 115 again, and the intermittent wheel 115 stops rotating. At this time, the intermittent wheel 115 has just rotated 90 degrees, and the driving cam 113 can limit the intermittent wheel 115 to prevent it from rotating. The driving cam 113 and the driving shaft 114 continue to rotate. After the driving cam 113 and the intermittent wheel 115 are disengaged, the driving shaft 114 will rotate into the intermittent wheel 115 and drive the intermittent wheel 115 to rotate. When the driving shaft 114 rotates out of the intermittent wheel 115, the driving cam 113 contacts the intermittent wheel 115 again, and the intermittent wheel 115 stops rotating. At this time, the intermittent wheel 115 has just rotated 90 degrees, and the powder box 8 has rotated a total of 180 degrees, completing the turning of the powder box 8, so that the wire drawing powder in the powder box 8 falls below the guide pipe 10 without pouring out the wire drawing powder. Subsequently, the straight rack 119 and the straight gear 1110 are disengaged, the straight gear 1110 stops rotating, and the slide plate 117 continues to move, so that the inclined plate 126 continues to move towards 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 towards each other. The spring 123 is compressed. The contact plate 122 drives the two semi-circular plates 124 to move towards each other. The two semi-circular plates 124 contact each other to form a guiding channel. Then the staff member passes the wire through the upper and lower electric conveying wheels 134. The electric conveying wheels 134 convey the wire leftward. The wire passes through the guide pipe 10 on the right and extends into the powder box 8. The wire will enter the guiding channel. The guiding channel guides the wire to prevent the wire from sagging, ensuring that the wire can pass through the powder box 8 smoothly, and the staff member does not need to adjust the angle and position of the wire, reducing the complexity of the operation, thereby improving the production efficiency. Subsequently, the wire passes through the guide pipe 10 on the left and moves out of the powder box 8. Finally, the wire passes through the drawing die 5. The staff member then controls the lead screw motor 118 to drive the slide plate 117 to move away from the powder box 8. The slide plate 117 on the right drives the straight rack 119 to move rightward. The straight rack 119 drives the straight gear 1110 to rotate in the reverse direction. The straight gear 1110 drives the driving cam 113 and the driving shaft 114 to rotate in the reverse direction through the gear box 112. The driving shaft 114 drives the powder box 8 to rotate 180 degrees in the reverse direction to reset the powder box 8, making the wire drawing powder in the powder box 8 flush with the guide pipe 10. The slide plate 117 continues to move,Continuously move the inclined plate 126 away from the powder box 8. The inclined plate 126 will be separated 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 semi-circular plates 124 move away from each other accordingly. The two semi-circular plates 124 are separated from each other, and the wire drawing powder will come into contact with the wire. The wire drawing powder can lubricate the wire. At this time, the electric conveying wheel 134 continues to convey the wire to the left, and then a pulling device is arranged on the left side of the frame 1. The wire is pulled to the left through the pulling device, so that the drawing die 5 performs a drawing process on the wire.,

[0038] Refer to 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 part of the left support plate 2. There is an opening (not shown in the figure) on the right side of the bottom of the U-shaped plate 3. The magnet 142 is connected to the upper left part of the collection box 141. The bottom of the U-shaped plate 3 is made of iron, so the magnet 142 can be adsorbed on the bottom of the U-shaped plate 3.,

[0039] When the wire moves out of the powder box 8, the residual wire 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 to save resources. The magnet 142 is adsorbed on the bottom of the U-shaped plate 3 to prevent the collection box 141 from sliding down. After the collection box 141 is filled with wire drawing powder, the collection box 141 is pulled downward, and the magnet 142 is separated from the U-shaped plate 3, and then the wire drawing powder in the collection box 141 is processed.,

[0040] Refer to Figure 8 It also includes a telescopic tube 15. The telescopic tube 15 is sleeved on the sliding rod 121. The two ends of the telescopic tube 15 are respectively connected to the powder box 8 and the semi-circular plate 124.,

[0041] The telescopic tube 15 can block the wire drawing powder to prevent it from falling into the gap between the sliding rod 121 and the powder box 8, ensuring that the sliding rod 121 can slide normally. When the semi-circular plate 124 moves, the telescopic tube 15 will expand and contract adaptively to ensure that the semi-circular plate 124 can move normally.,

[0042] Obviously, the above-described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. It only expresses the preferred implementation modes of the present invention, and the description is relatively specific and detailed. However, it cannot be understood as a limitation to the scope of the patent of the present invention.,

[0043] It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several deformations, quantity increases or decreases, improvements and substitutions can be made. Therefore, based on the embodiments in the present invention, all other embodiments obtained by those of ordinary skill in the art without creative labor fall within the protection scope of the present invention.,
