Description

Technical Field

[0001] This invention relates to the field of metal wire drawing technology, and more particularly to a metal wire forming device for manufacturing dish racks. Background Technology

[0002] Copper dish racks are kitchen storage tools made primarily of copper. They are commonly used for draining and storing dishes and tableware. Copper has natural antibacterial properties; copper ions can inhibit the growth of bacteria, fungi, and viruses, especially effective against common pathogens such as E. coli and Salmonella. As consumers become more sensitive to kitchen hygiene, copper tableware and storage tools are gradually becoming a standard feature of healthy living. Furthermore, copper dish racks have better resistance to pressure and deformation than plastic or ordinary metal materials, making them highly durable.

[0003] Announcement No. CN119303980A discloses an automatic wire drawing machine. By setting the drawing die inside the protective housing, the scraped lubricating powder will not be scattered into the air outside the device. The scraped lubricating powder can be reused through the conveying component and the vibration component. Preventing the lubricating powder from falling into the environment helps to reduce dust pollution in the air and workplace. The scraped lubricating powder is effectively and quickly recycled into the powder winding component, avoiding waste and frequent replenishment costs, thereby reducing production costs.

[0004] In related technologies, the manufacturing process of copper metal baskets requires the use of a coil drawing machine to draw wire into specified specifications. When drawing wire using this machine, the wire surface needs to be lubricated to reduce friction between the wire and the die. Most existing coil drawing machines use lubricating powder to lubricate the wire surface. However, lubricating powder is a solid particle with poor adhesion, easily detaching due to friction during high-speed drawing, leading to uneven lubrication, increasing the risk of localized wear, and providing almost no cooling capacity. Heat accumulation may cause grain coarsening on the wire surface, reducing mechanical properties.

[0005] Therefore, it is necessary to provide a metal wire forming device for manufacturing dish racks to solve the above-mentioned technical problems. Summary of the Invention

[0006] This invention provides a metal wire forming device for manufacturing dish racks, which solves the technical problem in the existing coil drawing machine that uses lubricating powder to lubricate the wire, resulting in poor wire drawing effect.

[0007] To solve the above-mentioned technical problems, the metal wire forming equipment for manufacturing dish racks provided by the present invention includes a frame, a guiding mechanism, a lubrication mechanism, a winding and drawing mechanism, wire, and a coating mechanism;

[0008] The guiding mechanism includes multiple fixed wheels mounted on one side of the top of the frame via a rotating rod and movable moving wheels located on the other side. The multiple fixed wheels and moving wheels are staggered to form a wire channel, through which the wire passes to the right and enters the lubrication mechanism.

[0009] The lubrication mechanism includes a lubrication box, a hose, a bracket, and a mounting plate. The mounting plate is fixedly mounted on the bottom of the frame via the bracket. A rotating shaft that rotates synchronously with a fixed wheel is rotatably connected to the center of the mounting plate.

The wire passes through the coating mechanism for lubrication and then enters the winding and drawing mechanism to the right. A rotating frame is fixed on the rotating shaft. Both ends of the rotating frame are rotatably connected to extrusion wheels that can squeeze the hose. The rotating shaft drives the rotating frame to rotate, causing the two extrusion wheels to repeatedly squeeze the hose and extract the oil.

[0012] A drawing die is fixedly mounted on the top of the frame, and a guide wheel is rotatably connected to the top of the frame and to the right of the drawing die.

[0013] The mounting plate is provided with a retaining ring, and the flexible hose is fixed to the inner wall of the retaining ring. The flexible hose enters from one side of the mounting plate and exits from the other side, forming a semi-circle inside the mounting plate.

[0014] Preferably, the drum drawing mechanism includes a rotating seat fixed to the right side of the top of the frame, a toothed disc rotatably connected to the inner side of the rotating seat, a drum fixed to the inner side of the toothed disc, a rotating rod rotatably connected to the inner side of the frame, a gear fixed to the top of the rotating rod, the gear meshing with the toothed disc, a protective frame fixed to the top of the frame, and a drive motor for driving the rotating rod to rotate at the bottom of the frame.

[0015] Preferably, the coating mechanism includes a swing frame fixed to the bottom end of the rotating shaft, a connecting rod rotatably connected to the top of the swing frame, a connecting frame rotatably connected to the right side of the connecting rod, a sliding frame fixed to the surface of the connecting frame by bolts, the top surface of the sliding frame slidingly connected to the inner side of the frame, a mounting plate fixed to the top of the sliding frame, a coating block provided on the inner side of the mounting plate, and the output end of the hose communicating with the mounting plate.

[0016] Preferably, the wire passes through the wiping block, and after the hose delivers the lubricating oil into the mounting plate, the wiping block absorbs the lubricating oil. An annular channel is provided on the inner side of the mounting plate for the circulation of lubricating oil.

[0017] Preferably, a heat dissipation mechanism is vertically rotatably connected to the inner side of the frame and the inner side of the drum. The heat dissipation mechanism includes a rotating shaft rotatably connected to the inner side of the frame, a cooling fan fixed at the top end of the rotating shaft, pulleys fixed on the surfaces of the rotating shaft and the rotating rod, and belts sleeved on the surfaces of the two pulleys.

[0018] Preferably, a conveying mechanism is fixedly provided on the left side of the top of the frame. The conveying mechanism includes a conveying frame fixedly provided on the left side of the top of the frame. A conveying cylinder is rotatably connected to the inner side of the conveying frame. A horizontal plate is fixedly provided on the inner side of the right side of the conveying frame. A guide wheel is provided on the top of the horizontal plate.

[0019] Preferably, a limiting mechanism is fixedly provided on the top of the conveyor frame. The limiting mechanism includes a mounting frame fixedly provided on the top of the conveyor frame. An adjusting bolt is threadedly connected to the inner side of the mounting frame. A limiting seat is rotatably connected to the bottom end of the adjusting bolt. A limiting wheel is rotatably connected to the inner side of the limiting seat.

[0020] Preferably, a support frame is fixedly provided at the bottom of the frame, and multiple support feet are threadedly connected to the bottom of the support frame. A flat plate is provided on the inner side of the support frame, and the bottom of the lubrication box is fixedly connected to the flat plate by bolts.

[0021] Compared with related technologies, the metal wire forming equipment for manufacturing dish racks provided by this invention has the following beneficial effects:

[0022] When drawing wire, lubricating oil is used to lubricate the wire and the inner wall of the drawing die. The lubricating oil is liquid and forms a continuous and stable lubricating film after covering the wire surface. This effectively isolates the wire from direct contact with the drawing die, reduces the coefficient of friction, and the lubricating oil can fill the micro gap between the drawing die and the material in real time as the wire deforms. This adapts to the high strain rate drawing process. The lubricating oil can absorb and carry away the frictional heat generated during the drawing process, preventing the material from softening or oxidizing and discoloring due to overheating of the drawing die and wire. This improves the quality of the wire after the drawing operation, and thus improves the aesthetics and quality of the finished dish rack.

[0023] When drawing wire, the wire moves to the right, and the fixed wheel drives the rotating shaft to rotate. The rotating shaft drives the rotating frame and the extrusion wheel to rotate, thereby actively pumping the lubricating oil to the output end of the hose. Furthermore, the output speed of the lubricating oil can be adaptively adjusted according to the wire drawing speed to ensure that the surface of the wire is always coated with lubricating oil and to avoid adding too much or too little lubricating oil.

[0024] When the shaft rotates, it drives the bottom swing frame to rotate. Under the action of the connecting rod and the connecting frame, the swing frame drives the sliding frame to move back and forth on the inside of the frame. This, in turn, drives the coating block to move back and forth on the surface of the wire through the mounting plate, so as to evenly apply the lubricating oil to the surface of the wire.

[0050] The realization of the objective, functional features and advantages of the present invention will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0051] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. 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.

[0052] This invention provides a metal wire forming device for manufacturing dish racks.

[0053] First embodiment:

[0054] Please see Figures 1 to 7 and Figure 10 A metal wire forming device for manufacturing dish racks includes a frame 1, a guiding mechanism 2, a lubrication mechanism 3, a drum drawing mechanism 4, a wire 5, and a coating mechanism 6.

[0055] The guiding mechanism 2 includes a plurality of fixed wheels 25 rotatably mounted on one side of the top of the frame 1 via a rotating rod and a movable wheel 23 located on the other side. The plurality of fixed wheels 25 and movable wheels 23 are arranged alternately to form a wire channel, through which the wire 5 passes to the right and enters the coating mechanism 6.

[0056] Two slide rails 21 are fixedly provided at the bottom of the frame 1. An adjustment seat 22 is slidably connected to the surface of the two slide rails 21. Multiple moving wheels 23 are rotatably connected to the adjustment seat 22 through a rotating rod. A threaded screw 24 is threadedly connected to the inner side of the frame 1. The front end of the threaded screw 24 is rotatably connected to the back of the adjustment seat 22.

[0057] Please combine Figure 3 and Figure 4 When the drum drawing mechanism 4 draws the wire 5, the wire 5 will move to the right. The moving wheel 23 and the fixed wheel 25 will clamp the wire 5. The movement of the wire 5 will drive the three moving wheels 23 to rotate counterclockwise and the three fixed wheels 25 to rotate clockwise.

[0058] Furthermore, when the diameter of the wire 5 changes, by rotating the threaded screw 24, the adjusting seat 22 can be moved forward or backward on the surface of the slide rail 21, thereby adjusting the working position of the three moving wheels 23 so that the moving wheels 23 and the fixed wheels 25 always form a clamping state on the wire 5.

[0059] The lubrication mechanism 3 includes a lubrication box 37, a hose 36, a bracket 31, and a mounting plate 32. The mounting plate 32 is fixedly mounted on the bottom of the frame 1 via the bracket 31. A rotating shaft 33, which rotates synchronously with a fixed wheel 25, is rotatably connected to the axis of the mounting plate 32. The hose 36 is connected to the lubrication box 37 and fixed on the surface of the mounting plate 32. After circling half a turn, it connects to the coating mechanism 6. The wire 5 passes through the coating mechanism 6 for lubrication and then enters the winding and drawing mechanism 4 to the right. A rotating frame 34 is fixed on the rotating shaft 33. Both ends of the rotating frame 34 are rotatably connected to extrusion wheels 35 that can squeeze the hose 36. The rotating shaft 33 drives the rotating frame 34 to rotate, causing the two extrusion wheels 35 to repeatedly squeeze the hose 36 to extract the oil.

[0060] The rotating shaft 33 can be fixedly connected to the axle of a fixed wheel 25, i.e., the rotating rod, to achieve synchronous rotation, or it can be rotatably connected to the bottom of the frame 1 and achieve synchronous rotation through a synchronous belt and a synchronous pulley. This allows the installation position of the rotating shaft 33 to be adjusted according to requirements.

[0061] A drawing die 13 is fixedly provided on the top of the frame 1, and a guide wheel 14 is rotatably connected to the top of the frame 1 and to the right of the drawing die 13.

[0062] Preferably, the drawing die 13 is internally threaded with a drawing die, which can be replaced according to the drawing requirements of the wire 5;

[0063] The mounting plate 32 is provided with a retaining ring, and the flexible hose 36 is fixed to the inner wall of the retaining ring. The flexible hose 36 enters from one side of the mounting plate 32 and exits from the other side, forming a semi-circle inside the mounting plate 32.

[0064] Please combine Figures 5 to 7 When the right fixed wheel 25 rotates clockwise, it will simultaneously drive the bottom rotating shaft 33 to rotate clockwise. The rotation of the rotating shaft 33 will drive the rotating frame 34 and the two extrusion wheels 35 to rotate clockwise. Through the continuous rotation of the two extrusion wheels 35, the hose 36 is squeezed and released, creating a negative pressure inside the hose 36, thereby drawing the lubricating oil in the lubrication box 37 to the output end of the hose 36.

[0065] Furthermore, when the drum 43 rotates at high speed to pull the wire 5, the wire 5 moves to the right at a faster speed, which in turn increases the rotation speed of the fixed wheel 25. The rapid rotation of the fixed wheel 25 drives the rotating frame 34 and the extrusion wheel 35 to rotate rapidly through the rotating shaft 33. The two extrusion wheels 35 rotate faster, thereby increasing the speed at which the hose 36 draws lubricating oil. The output speed of the lubricating oil can be adaptively adjusted according to the pulling speed of the wire 5 to ensure that the surface of the wire 5 is always coated with lubricating oil. In addition, the adaptive adjustment of the output speed of the lubricating oil according to the pulling speed of the wire 5 can avoid waste caused by adding too much lubricating oil or insufficient lubrication of the wire 5, which would increase the pulling friction.

[0066] Preferably, the hose 36 is elastic, and the hose 36 can automatically return to its original shape after the compression wheel 35 releases the compression on the hose 36;

[0067] The coating mechanism 6 includes a swing frame 61 fixed to the bottom end of the rotating shaft 33. A connecting rod 62 is rotatably connected to the top of the swing frame 61. A connecting frame 63 is rotatably connected to the right side of the connecting rod 62. A sliding frame 64 is fixed to the surface of the connecting frame 63 by bolts. The top surface of the sliding frame 64 is slidably connected to the inner side of the frame 1. A mounting plate 65 is fixed to the top of the sliding frame 64. A coating block 66 is provided on the inner side of the mounting plate 65. The output end of the hose 36 is connected to the mounting plate 65.

[0068] The mounting plate 65 has a through hole, and the hose 36 is connected to the through hole. Oil seeps into the coating block 66 through the through hole to lubricate the wire 5.

[0069] The coating block 66 can be a ring structure made of materials such as sponge to allow oil to penetrate, or it can be a ring made of other elastic and flexible materials with densely packed micropores so that the oil can flow through the micropores to the inside and contact the wire 5.

[0070] Please combine Figure 10 When the rotating shaft 33 rotates, it will drive the bottom swing frame 61 to rotate. Under the action of the connecting rod 62 and the connecting frame 63, the rotation of the swing frame 61 will drive the sliding frame 64 to move back and forth on the inside of the frame 1. The back and forth movement of the sliding frame 64 will drive the coating block 66 to move back and forth on the surface of the wire 5 through the mounting plate 65, thereby evenly applying the lubricating oil to the surface of the wire 5.

[0071] Furthermore, when the sliding frame 64 drives the wiping block 66 to move back and forth on the surface of the wire 5 through the mounting plate 65, the wiping block 66 can also clean the surface of the wire 5. After the wiping block 66 has been working for a certain period of time, mud-like substances containing lubricating oil will be formed on both sides. By cleaning the surface of the wire 5, the drawing die can be prevented from wearing out too quickly due to dust, and the drawing quality of the wire 5 can be improved.

[0072] The wire 5 passes through the wiping block 66. After the hose 36 delivers the lubricating oil into the mounting plate 65, the wiping block 66 will absorb the lubricating oil. The inner side of the mounting plate 65 is provided with an annular channel for the circulation of lubricating oil.

[0073] In this embodiment, unlike existing coil drawing machines, lubricating oil is used to lubricate the wire 5 and the inner wall of the drawing die during the drawing operation. The lubricating oil is liquid and forms a continuous and stable lubricating film after covering the surface of the wire 5, effectively isolating the wire 5 from direct contact with the drawing die, reducing the coefficient of friction. Furthermore, the lubricating oil can fill the micro gap between the drawing die and the material in real time as the wire 5 deforms, adapting to the high strain rate drawing process. The lubricating oil can absorb and carry away the frictional heat generated during the drawing process, avoiding material softening or oxidation discoloration caused by overheating of the drawing die and the wire 5, improving the quality of the wire 5 after the drawing operation, and thus improving the aesthetics and quality of the manufactured dish rack.

[0074] Unlike existing coil drawing machines that use lubricating oil for lubrication, this invention, when drawing wire 5, uses the rightward movement of wire 5 to drive the rotating shaft 33 to rotate under the action of the fixed wheel 25. The rotating shaft 33 drives the rotating frame 34 and the extrusion wheel 35 to rotate, thereby actively pumping lubricating oil to the output end of the hose 36. Furthermore, the output speed of the lubricating oil can be adaptively adjusted according to the drawing speed of wire 5 to ensure that the surface of wire 5 is always coated with lubricating oil, avoiding excessive or insufficient lubricating oil addition.

[0075] When the rotating shaft 33 rotates, it will drive the bottom swing frame 61 to rotate. Under the action of the connecting rod 62 and the connecting frame 63, the rotation of the swing frame 61 will drive the sliding frame 64 to move back and forth on the inside of the frame 1. This will drive the coating block 66 to move back and forth on the surface of the wire 5 through the mounting plate 65, so as to evenly apply the lubricating oil to the surface of the wire 5.

[0076] Second embodiment:

[0077] Please see Figure 8 , Figure 9 and Figure 11The roller drawing mechanism 4 is located on the top of the frame 1 and to the right of the coating mechanism 6, and is used to draw the wire 5. The roller drawing mechanism 4 includes a rotating seat 41 fixed to the right side of the top of the frame 1. A toothed disc 42 is rotatably connected to the inner side of the rotating seat 41. A roller 43 is fixed to the inner side of the toothed disc 42. A rotating rod 44 is rotatably connected to the inner side of the frame 1. A gear 45 is fixed to the top of the rotating rod 44. The gear 45 meshes with the toothed disc 42. A protective frame 46 is fixed to the top of the frame 1. A drive motor 47 for driving the rotating rod 44 to rotate is provided at the bottom of the frame 1.

[0078] Please combine Figure 8 and Figure 9 Start the drive motor 47, and the drive motor 47 rotates to drive the rotating rod 44 to rotate. The rotating rod 44 rotates to drive the gear 45 to rotate. The gear 45 rotates to drive the toothed disc 42 to rotate inside the rotating seat 41. The rotation of the toothed disc 42 drives the drum 43 to rotate. The rotation of the drum 43 then performs the drawing process on the wire 5.

[0079] A heat dissipation mechanism 7 is vertically rotatably connected to the inner side of the frame 1 and the inner side of the drum 43. The heat dissipation mechanism 7 includes a rotating shaft 71 rotatably connected to the inner side of the frame 1. A cooling fan 72 is fixedly provided at the top end of the rotating shaft 71. Pulleys 73 are fixedly provided on the surfaces of the rotating shaft 71 and the rotating rod 44. A belt 74 is sleeved on the surface of the two pulleys 73.

[0080] Please combine Figure 8 and Figure 11 When the rotating rod 44 rotates, it will drive the right pulley 73 to rotate. The rotation of the right pulley 73, under the action of the belt 74, will drive the left pulley 73 to rotate. The rotation of the left pulley 73 will drive the rotating shaft 71 and the cooling fan 72 to rotate, thereby cooling the drum 43.

[0081] Preferably, the surface of the roll 43 is coated with a tungsten carbide or ceramic coating to improve wear resistance.

[0082] In this embodiment, when the drive motor 47 drives the rotating rod 44 and gear 45 to rotate, and the toothed disc 42 drives the drum 43 to rotate to draw the wire 5, the rotation of the rotating rod 44 will drive the rotating shaft 71 and the cooling fan 72 to rotate through the pulley 73 and belt 74. The cooling fan 72 will dissipate heat from the drum 43, thus preventing the copper wire from generating heat due to friction between the copper wire and the drum 43 when the wire 5 is drawn at high speed, which would lead to accelerated wear on the surface of the drum 43 or even oxidation and discoloration of the copper wire after drawing, thereby improving the drawing effect of the wire 5.

[0083] Third embodiment:

[0084] Please see Figure 12 and Figure 3 A conveying mechanism 8 is fixedly provided on the left side of the top of the frame 1. The conveying mechanism 8 includes a conveying frame 81 fixedly provided on the left side of the top of the frame 1. A conveying cylinder 82 is rotatably connected to the inner side of the conveying frame 81. A horizontal plate 83 is fixedly provided on the inner side of the right side of the conveying frame 81. A guide wheel 84 is provided on the top of the horizontal plate 83.

[0085] Please combine Figure 12 When the wire 5 is drawn by the drum drawing mechanism 4, the wire 5 moves to the right and drives the conveyor drum 82 to rotate. The guide wheel 84 can provide stability when the wire 5 moves.

[0086] The top of the conveyor frame 81 is fixedly provided with a limiting mechanism 9. The limiting mechanism 9 includes a mounting frame 91 fixedly provided on the top of the conveyor frame 81. An adjusting bolt 92 is threadedly connected to the inner side of the mounting frame 91. The bottom end of the adjusting bolt 92 is rotatably connected to a limiting seat 93. The inner side of the limiting seat 93 is rotatably connected to a limiting wheel 94.

[0087] Please combine Figure 13 By turning the adjusting bolt 92 downwards, the adjusting bolt 92 will drive the limiting seat 93 and the limiting wheel 94 to move downwards. The downward movement of the limiting wheel 94 will squeeze the wire 5, preventing the wire 5 from driving the conveyor cylinder 82 to rotate rapidly during the drawing process.

[0088] The bottom of the frame 1 is fixedly provided with a support frame 10, and the bottom of the support frame 10 is threadedly connected with a plurality of support feet 11. A flat plate 12 is provided on the inner side of the support frame 10, and the bottom of the lubrication box 37 is fixedly connected to the flat plate 12 by bolts.

[0089] In this embodiment, before the wire 5 is drawn using the drum drawing mechanism 4, the adjusting bolt 92 is turned downwards. The adjusting bolt 92 drives the limiting seat 93 and the limiting wheel 94 to move downwards. The downward movement of the limiting wheel 94 squeezes the wire 5, thus preventing the wire 5 from driving the conveying drum 82 to rotate rapidly during the drawing process.

[0090] Please refer to the reference again. Figures 1 to 13 The working principle of the metal wire forming equipment for manufacturing dish racks provided by this invention is as follows:

[0091] Step S1: First, the wire 5 is passed through the drawing die 13 from the opposite side of the moving wheel 23 and the fixed wheel 25. Then, the right end of the wire 5 is wound around the surface of the drum 43 with the help of an external object. The drive motor 47 is started. The rotation of the drive motor 47 drives the rotating rod 44 to rotate. The rotation of the rotating rod 44 drives the gear 45 to rotate. The rotation of the gear 45 drives the toothed disc 42 to rotate inside the rotating seat 41. The rotation of the toothed disc 42 drives the drum 43 to rotate. The rotation of the drum 43 then draws the wire 5. After the wire 5 passes through the drawing die 13, it will become a copper wire of a specified thickness for manufacturing copper bowl and plate racks.

[0092] In step S2, when the wire 5 is pulled in step S1, the wire 5 will move to the right, and the moving wheel 23 and the fixed wheel 25 will clamp the wire 5. The movement of the wire 5 will drive the three moving wheels 23 to rotate counterclockwise and the three fixed wheels 25 to rotate clockwise.

[0093] In step S3, when the right fixed wheel 25 rotates clockwise, it will simultaneously drive the bottom rotating shaft 33 to rotate clockwise. The rotation of the rotating shaft 33 will drive the rotating frame 34 and the two extrusion wheels 35 to rotate clockwise. Through the continuous rotation of the two extrusion wheels 35, the hose 36 is squeezed and released, creating a negative pressure inside the hose 36, thereby drawing the lubricating oil in the lubrication box 37 to the output end of the hose 36.

[0094] In step S4, when the rotating shaft 33 rotates, it will drive the bottom swing frame 61 to rotate. Under the action of the connecting rod 62 and the connecting frame 63, the rotation of the swing frame 61 will drive the sliding frame 64 to move back and forth on the inner side of the frame 1. The left and right reciprocating movement of the sliding frame 64 will drive the coating block 66 to move back and forth on the surface of the wire 5 through the mounting plate 65, thereby evenly applying the lubricating oil to the surface of the wire 5.

[0095] In step S5, when the rotating rod 44 rotates, it will drive the right pulley 73 to rotate. The rotation of the right pulley 73, under the action of the belt 74, will drive the left pulley 73 to rotate.
