Description

Technical Field

[0001] This invention belongs to the field of sheet metal coiling equipment, and particularly relates to a sheet metal coiling equipment for automotive parts production. Background Technology

[0002] A coiler is an auxiliary device in a steel rolling mill that coils hot-rolled or cold-rolled steel into coils. On hot strip mills, cold strip mills, and wire rod mills, it is located after the finishing mill stand; on single-stand reversible cold strip mills, it is installed before or after the mill. In addition, it is also installed in various finishing units such as continuous pickling units, slitting units, annealing units, and coating units.

[0003] Existing sheet metal coiling equipment has a relatively simple structure and can only perform simple sheet metal coiling. It cannot treat the dust on the sheet metal surface. When the sheet metal is to be used later, the dust on the sheet metal must be treated, which is inconvenient. At the same time, after the coiled sheet metal is exposed to the air for a long time, its surface is prone to rust, which reduces the quality of the sheet metal.

[0004] To avoid the aforementioned technical problems, it is indeed necessary to provide a sheet metal coiling device for automotive parts production to overcome the deficiencies in the prior art. Summary of the Invention

[0005] The purpose of this invention is to provide a sheet metal coiling device for automotive parts production, which aims to solve the problems of existing sheet metal coiling devices being unable to handle dust and being prone to rust.

[0006] This invention is implemented as follows: a sheet metal coiling device for automotive parts production includes a base, a power box mounted on the base, a drive motor housed within the power box, a coiling roller fixedly connected to the output end of the drive motor, the coiling roller having a slot, a rotating rod rotatably connected to the side of the base, a torsion spring disposed between the rotating rod and the base, and a mounting bracket fixedly connected to the rotating rod. The device also includes:

[0007] Two heating and soot blowing mechanisms are provided, both of which are mounted on a base. The heating and soot blowing mechanisms are used to heat and blow soot onto both sides of the sheet metal.

[0008] The pressure roller is rotatably connected to the mounting frame and abuts against the surface of the take-up roller. The pressure roller is used to compact the sheet metal wound on the take-up roller.

[0009] An oiling mechanism is mounted on a mounting frame. One end of the oiling mechanism is connected to the inside of a pressure roller. The pressure roller has several oil drip holes. The oiling mechanism is used to apply a protective oil to the sheet metal surface.

[0010] A further technical solution includes a heating and soot blowing mechanism comprising a mounting box, a heating roller rotatably connected to the side of the mounting box, multiple heating tubes fixedly connected inside the heating roller, the multiple heating tubes being evenly distributed around the axis of the heating roller, an electrode ring being provided at one end of the heating roller, an electric slip ring adapted to the electrode ring being provided inside the mounting box, the electrode ring and the electric slip ring being electrically connected, the electrode ring being electrically connected to all the heating tubes, a piston being slidably connected inside the heating roller, a reciprocating screw being fixedly connected to the side of the piston, a fixing nut being fixedly connected to the side wall of the mounting box, the fixing nut being threadedly connected to the reciprocating screw, a first sliding groove for the reciprocating screw to move being provided on the base, and a number of soot blowing holes being provided on the side of the heating roller, the number of soot blowing holes and the heating tubes being staggered.

[0011] A further technical solution also includes an adjustment mechanism, which is installed on the base. One of the heating and soot blowing mechanisms is slidably installed on the base. The base has a second sliding groove for the heating and soot blowing mechanism to move. One end of the adjustment mechanism is connected to the movable heating and soot blowing mechanism. The adjustment mechanism is used to drive the heating and soot blowing mechanism to move. The other heating and soot blowing mechanism is fixedly installed on the base.

[0012] In a further technical solution, the adjusting mechanism includes a screw, which is threadedly connected to the base. One end of the screw is rotatably connected to the mounting box on the movable heating and soot blowing mechanism, and a handwheel is fixedly connected to the top of the screw.

[0013] A further technical solution is that the oiling mechanism includes:

[0014] The oil dripping pipe has a cavity inside the pressure roller and is rotatably connected inside the cavity. The oil dripping pipe has several oil outlet holes.

[0015] A sponge body, the sponge body filling the cavity, and the oil drip tube disposed within the sponge body;

[0016] An oil storage tank is fixedly connected to a mounting frame and is used to store isolation oil.

[0017] Two oil pumps are fixedly installed on the oil storage tank. The two oil pumps are connected to both ends of the drip pipe through oil delivery pipes. The oil pumps are used to pump the isolated oil in the oil storage tank into the drip pipe.

[0018] A transmission mechanism is connected between the pressure roller and the oil pump. When the pressure roller rotates with the sheet metal, the transmission mechanism provides power to the oil pump.

[0019] A further technical solution includes a circular housing with an inlet pipe and an outlet pipe connected to both sides of the housing. The inlet pipe is connected to an oil storage tank, and the outlet pipe is connected to one end of an oil delivery pipe. A drive wheel is rotatably connected inside the circular housing. The drive wheel is positioned eccentrically on the circular housing and abuts against the inner bottom wall of the circular housing. Three mounting slots are provided on the drive wheel, and a sliding actuating block is slidably connected inside each of the three mounting slots. A compression spring is connected between the actuating block and the mounting slot, and one end of the actuating block abuts against the inner wall of the circular housing.

[0020] In a further technical solution, the transmission mechanism includes a first sprocket and a second sprocket. The first sprocket is fixedly connected to one end of the pressure roller. A transmission rod is fixedly connected to the side of one of the drive wheels. The second sprocket is fixedly connected to the end of the transmission rod that extends out of the circular housing. The second sprocket and the first sprocket are connected by a chain drive. The other end of the transmission rod is fixedly connected to the side of a drive wheel inside another oil pump.

[0021] A further technical solution also includes a limiting component, which includes a stud fixedly connected to one end of the take-up roller, a limiting element slidably connected to the stud, and a limiting nut threadedly connected to the stud, the limiting nut abutting against the limiting element.

[0022] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0023] 1. The moving sheet metal drives the heating roller to rotate, which in turn drives the piston to rotate. The piston then drives the reciprocating screw to rotate. Under the action of the fixed nut, the reciprocating screw moves back and forth relative to the fixed nut. The reciprocating screw drives the piston to move back and forth inside the heating roller. The piston compresses the space inside the heating roller, thereby squeezing out the air inside the heating roller. Under the constraint of the blowing hole, this air forms an airflow, which blows dust off the sheet metal surface. This device heats the sheet metal while blowing dust off its surface, preventing dust from sticking to the sheet metal when applying the release oil later and avoiding the need for further dust blowing treatment on the sheet metal later.

[0024] 2. The moving sheet metal also drives the pressure roller to rotate, which in turn drives the first sprocket to rotate. The first sprocket drives the second sprocket to rotate via a chain, which in turn drives the drive wheel to rotate via a rotating rod. The drive wheel drives the actuating block to rotate, which in turn drives the isolation oil inside the circular housing into the oil supply pipe. Then the isolation oil enters the dripping pipe, and the isolation oil flows into the sponge body from the oil outlet. Excess isolation oil in the sponge body drips from the dripping hole onto the sheet metal, protecting the sheet metal surface and preventing it from rusting.

[0025] 3. After the sheet metal is wound onto the take-up roller, rotate the limit nut. The limit nut will drive the limit component to move, thereby pressing the sheet metal onto the machine base, making the sheet metal winding more neat. Attached Figure Description

[0034] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0035] The specific implementation of the present invention will be described in detail below with reference to specific embodiments.

[0036] like Figure 1-7As shown, this invention provides a sheet metal winding device for automotive parts production, comprising a base 1, a power box on the base 1 containing a drive motor, a winding roller 2 fixedly connected to the output end of the drive motor, a slot on the winding roller 2, and the winding roller 2 winding the sheet metal by inserting one end of the sheet metal into the slot. A rotating rod 3 is rotatably connected to the side of the base 1, a torsion spring is provided between the rotating rod 3 and the base 1, and a mounting bracket 4 is fixedly connected to the rotating rod 3. The device also includes:

[0037] Two heating and blowing mechanisms 5 are installed on the machine base 1. The sheet metal is passed between the two heating and blowing mechanisms 5. The heating and blowing mechanisms 5 are used to heat and blow away dust on both sides of the sheet metal. Heating the sheet metal by the heating and blowing mechanisms 5 will soften the sheet metal, making it easier for the winding roller 2 to wind the sheet metal. Blowing away dust on both sides of the sheet metal by the heating and blowing mechanisms 5 will remove the dust from the sheet metal, preventing dust from sticking to the sheet metal when applying the release oil later, and also preventing the sheet metal from being blown away again later.

[0038] The pressure roller 6 is rotatably connected to the mounting frame 4. The pressure roller 6 abuts against the surface of the winding roller 2. The pressure roller 6 is used to compact the sheet metal wound on the winding roller 2, so that the sheet metal is wound more tightly, the volume of the wound sheet metal is reduced, and it is easier to store.

[0039] The oiling mechanism 7 is mounted on the mounting frame 4. One end of the oiling mechanism 7 is connected to the inside of the pressure roller 6. The pressure roller 6 has several oil drip holes 10. The oiling mechanism 7 is used to apply isolation oil to the sheet metal surface to protect the sheet metal and prevent it from rusting.

[0040] In embodiments of the present invention, such as Figure 3-4 As shown, in a preferred embodiment of the present invention, the heating and soot blowing mechanism 5 includes a mounting box 51. A heating roller 52 is rotatably connected to the side of the mounting box 51. Multiple heating tubes 53 are fixedly connected inside the heating roller 52, and the multiple heating tubes 53 are evenly distributed around the axis of the heating roller 52. An electrode ring 54 is provided at one end of the heating roller 52. An electric slip ring 55 adapted to the electrode ring 54 is provided inside the mounting box 51. The electrode ring 54 and the electric slip ring 55 are electrically connected. The electrode ring 54 and all the heating tubes 53 are electrically connected. A piston 56 is slidably connected inside the heating roller 52. A reciprocating screw 57 is fixedly connected to the side of the piston 56. A fixing nut 58 is fixedly connected to the side wall of the mounting box 51. The fixing nut 58 and the reciprocating screw 57 are threadedly connected. A first sliding groove is provided on the machine base 1 for the reciprocating screw 57 to move. Several soot blowing holes 59 are provided on the side of the heating roller 52. The several soot blowing holes 59 and the heating tubes 53 are arranged alternately.

[0041] The sheet metal is passed between the two heating rollers 52. The power supply to the electric slip ring 55 is turned on. The electric slip ring 55 is electrically connected to the heating tube 53 through the electrode ring 54, thereby causing the heating tube 53 to heat up. The heating tube 53 heats the sheet metal. As the sheet metal is wound, under the action of friction, the sheet metal drives the heating roller 52 to rotate. The heating roller 52 drives the piston 56 to rotate. The piston 56 drives the reciprocating screw 57 to rotate. Under the action of the fixing nut 58, the reciprocating screw 57 moves back and forth relative to the fixing nut 58. The reciprocating screw 57 drives the piston 56 to move back and forth inside the heating roller 52. The piston 56 will squeeze the space inside the heating roller 52, thereby squeezing the air inside the heating roller 52 out of the heating roller 52. Under the constraint of the blowing hole 59, this part of the air will form an airflow, which will blow the dust off the surface of the sheet metal.

[0042] In embodiments of the present invention, such as Figure 2 As shown, in a preferred embodiment of the present invention, an adjustment mechanism 8 is also included. The adjustment mechanism 8 is mounted on the base 1. One of the heating and soot blowing mechanisms 5 is slidably mounted on the base 1. The base 1 has a second sliding groove for the heating and soot blowing mechanism 5 to move. One end of the adjustment mechanism 8 is connected to the movable heating and soot blowing mechanism 5. The adjustment mechanism 8 is used to drive the heating and soot blowing mechanism 5 to move. The other heating and soot blowing mechanism 5 is fixedly mounted on the base 1. Thus, the distance between the two heating and soot blowing mechanisms 5 can be adjusted, so that the device can adapt to sheet metal of different thicknesses.

[0043] In embodiments of the present invention, such as Figure 2 As shown, in a preferred embodiment of the present invention, the adjusting mechanism 8 includes a screw 81, which is threadedly connected to the base 1. One end of the screw 81 is rotatably connected to the mounting box 51 on the movable heating and soot blowing mechanism 5, and a handwheel 82 is fixedly connected to the top of the screw 81.

[0044] Turning the handwheel 82 causes the screw 81 to rotate, which in turn causes the mounting box 51 to rise and fall. The mounting box 51 then causes the heating roller 52 to rise and fall, thereby adjusting the distance between the two heating rollers 52 on the two heating and blowing mechanisms 5.

[0045] In embodiments of the present invention, such as Figure 5-7 As shown, in a preferred embodiment of the present invention, the oiling mechanism 7 includes:

[0046] The oil dripping pipe 71 is rotatably connected inside the cavity of the pressure roller 6, and the oil dripping pipe 71 is provided with several oil outlet holes 72.

[0047] The sponge body 73 is filled in the cavity, and the oil dripping pipe 71 is set in the sponge body 73. The isolation oil discharged from the oil dripping pipe 71 will fall onto the sponge body 73, and the excess isolation oil on the sponge body 73 will fall onto the sheet metal surface through the oil dripping hole 10.

[0048] Oil storage tank 74, which is fixedly connected to the mounting frame 4, is used to store isolation oil;

[0049] Two oil pumps 75 are fixedly installed on the oil storage tank 74. The two oil pumps 75 are connected to both ends of the drip pipe 71 through the oil delivery pipe 76. The oil pumps 75 are used to pump the isolation oil in the oil storage tank 74 into the drip pipe 71.

[0050] The transmission mechanism 77 is connected between the pressure roller 6 and the oil pump 75. When the pressure roller 6 rotates with the sheet metal, the transmission mechanism 77 provides power to the oil pump 75. When the pressure roller 6 stops rotating, the oil pump 75 will no longer pump oil to the oil dripping pipe 71, thereby preventing the isolation oil on the pressure roller 6 from dripping and avoiding waste of isolation oil.

[0051] In embodiments of the present invention, such as Figure 7 As shown, in a preferred embodiment of the present invention, the oil pump 75 includes a circular housing 751. An oil inlet pipe 752 and an oil outlet pipe 753 are respectively connected to both sides of the circular housing 751. The oil inlet pipe 752 is connected to an oil storage tank 74, and the oil outlet pipe 753 is connected to one end of an oil delivery pipe 76. A drive wheel 754 is rotatably connected inside the circular housing 751. The drive wheel 754 is positioned at an eccentric position on the circular housing 751 and abuts against the bottom inner wall of the circular housing 751. Three mounting slots are provided on the drive wheel 754, and a moving block 755 is slidably connected inside each of the three mounting slots. A compression spring 756 is connected between the moving block 755 and the mounting slot. One end of the moving block 755 abuts against the inner wall of the circular housing 751, and under the action of the compression spring 756, the moving block 755 always abuts against the inner wall of the circular housing 751.

[0052] In use, the isolation oil in the oil storage tank 74 enters the circular housing 751 through the oil inlet pipe 752. The pressure roller 6 drives the drive wheel 754 to rotate through the transmission mechanism 77. The drive wheel 754 drives the actuating block 755 to rotate. The actuating block 755 will drive the isolation oil to rotate to the side of the oil outlet pipe 753. Since the drive wheel 754 is in contact with the bottom of the circular housing 751, the isolation oil cannot pass through the bottom of the circular housing 751. Therefore, the isolation oil in the circular housing 751 can only be pumped out from the oil outlet pipe 753.

[0053] In embodiments of the present invention, such as Figure 5As shown, in a preferred embodiment of the present invention, the transmission mechanism 77 includes a first sprocket 771 and a second sprocket 772. The first sprocket 771 is fixedly connected to one end of the pressure roller 6. A transmission rod 773 is fixedly connected to the side of one of the drive wheels 754. The second sprocket 772 is fixedly connected to the end of the transmission rod 773 that extends out of the circular housing 751. The second sprocket 772 and the first sprocket 771 are connected by a chain 774. The other end of the transmission rod 773 is fixedly connected to the side of the drive wheel 754 inside another oil pump 75.

[0054] When the take-up roller 2 winds the sheet metal, the sheet metal drives the pressure roller 6 to rotate. The pressure roller 6 drives the first sprocket 771 to rotate. The first sprocket 771 drives the second sprocket 772 to rotate through the chain 774. The second sprocket 772 drives the transmission rod 773 to rotate. The transmission rod 773 drives the two drive wheels 754 to rotate, which in turn allows the oil pump 75 to pump out the isolation oil in the oil storage tank 74.

[0055] In embodiments of the present invention, such as Figure 1 As shown, in a preferred embodiment of the present invention, a limiting component 9 is also included. The limiting component 9 includes a stud 91 fixedly connected to one end of the take-up roller 2. A limiting member 92 is slidably connected to the stud 91. A limiting nut 93 is also threadedly connected to the stud 91. The limiting nut 93 abuts against the limiting member 92. After the sheet metal is wound onto the take-up roller 2, the limiting nut 93 is rotated, and the limiting nut 93 drives the limiting member 92 to move, thereby causing the limiting member 92 to press the sheet metal onto the machine base 1, making the sheet metal winding more neat.

[0056] In use, the sheet metal is passed between the two heating rollers 52. The handwheel 82 is turned, causing the screw 81 to rotate. The screw 81 moves the mounting box 51, which in turn lowers the heating rollers 52, ensuring both rollers 52 are in contact with the sheet metal. Then, the mounting bracket 4 is lifted, and one end of the sheet metal is inserted into the slot on the take-up roller 2. The limit nut 93 is turned, causing the limit member 92 to move and clamp one side of the sheet metal. Finally, the power to the drive motor is turned on. The machine drives the take-up roller 2 to rotate, which winds the sheet metal. The power supply to the slip ring 55 is then turned on. The slip ring 55 is electrically connected to the heating tube 53 via the electrode ring 54, thus turning on the power supply to the heating tube 53. The heating tube 53 generates heat, which in turn heats the sheet metal passing through the heating roller 52. Simultaneously, the moving sheet metal also drives the heating roller 52 to rotate. The heating roller 52 drives the piston 56 to rotate, which in turn drives the reciprocating screw 57 to rotate. Under the action of the fixing nut 58, the reciprocating screw 57... The reciprocating screw 57 drives the piston 56 to reciprocate within the heating roller 52, causing the fixed nut 58 to move back and forth. The piston 56 compresses the space inside the heating roller 52, forcing air out. Under the constraint of the blowing hole 59, this air forms an airflow that blows dust off the sheet metal surface. Simultaneously, the moving sheet metal also drives the pressure roller 6 to rotate, which in turn drives the first sprocket 771 to rotate. The first sprocket 771 is connected to the chain 774... The second sprocket 772 rotates, and the second sprocket 772 drives the drive wheel 754 to rotate through the transmission rod 773. The drive wheel 754 drives the actuating block 755 to rotate, and the actuating block 755 drives the isolation oil inside the circular housing 751 into the oil supply pipe 76. Then the isolation oil enters the drip pipe 71. The isolation oil flows into the sponge body 73 from the oil outlet 72. The excess isolation oil in the sponge body 73 will drip from the drip hole 10 onto the sheet metal, protecting the sheet metal surface and preventing it from rusting.

[0057] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.

[0058] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
