Description

Technical Field

[0001] This invention relates to the field of milling machine technology, specifically a double-sided milling machine for steel plates. Background Technology

[0002] In welded pipe production, the thickness of the steel plate affects the welding quality. As the thickness of the steel plate increases, the penetration rate of the welding wire will gradually decrease, resulting in problems such as slag inclusion and incomplete penetration during the welding process. In order to ensure the welding quality, the edge of the steel plate needs to be milled to remove the waste edge and form the bevel required for welding, providing good conditions for forming and welding, and obtaining the precise working width required for the forming process.

[0003] Chinese invention patent authorization announcement number CN116160047B proposes a steel plate beveling and milling machine. The invention describes that "a conveyor belt and a milling mechanism are set on the frame. The steel plate moves on the conveyor belt and is beveled and milled when it passes through the milling mechanism. A changing edge mechanism is added to the frame, and a set of milling mechanisms is set on both the front and rear sides of the changing edge mechanism. After passing through the first set of milling mechanisms, the beveling of one side edge is completed. As it continues to be conveyed, it passes through the changing edge mechanism, and is flipped with the help of the changing edge mechanism. Then it continues to be conveyed to the second set of milling mechanisms to complete the beveling of the other side edge."

[0004] The steel plate beveling and milling machine first mills one side of the steel plate to mill the other side. In order to mill the other side of the steel plate, the plate needs to be flipped to a designated position, which is cumbersome, time-consuming and labor-intensive, and affects the processing efficiency. Therefore, a double-sided steel plate milling machine is proposed to solve the above problems. Summary of the Invention

The output end of the reducer passes through the horizontal plate and is detachably installed with a milling cutter. Through holes are opened in the inside of the horizontal plate and the side wall of the second chamber. A discharge hopper is fixedly installed at an incline inside the two through holes.

[0010] Furthermore, the first limiting mechanism includes a side plate, which is fixedly connected to the outer side wall of the second compartment.

Then, the flipping mechanism moves the milling mechanism to a designated position, ensuring both milling mechanisms are in contact with the sides of the steel plate. Next, the first, second, and third limiting mechanisms are moved to designated positions, ensuring the first limiting mechanism is in contact with the sides, the second limiting mechanism with the top, and the third limiting mechanism with the bottom. During horizontal movement, the first limiting mechanism limits the sides, the second limiting mechanism limits the top, and the third limiting mechanism limits the bottom. Finally, the milling mechanism mills both sides of the steel plate. This eliminates the need to flip the steel plate, simplifying operation, saving time and effort, and improving processing efficiency. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. 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.

[0020] Please see Figure 1-2 The steel plate double-sided milling machine in this embodiment includes two adjustment mechanisms 1, which are arranged opposite to each other. A flipping mechanism 2 is detachably installed on the top of each adjustment mechanism 1. A milling mechanism 3 is fixedly installed inside each of the two flipping mechanisms 2. A first limiting mechanism 4 is fixedly installed on the outer wall of each of the two flipping mechanisms 2. A second limiting mechanism 5 is fixedly installed on the top of each of the two flipping mechanisms 2. A third limiting mechanism 6 is fixedly installed inside each of the two flipping mechanisms 2. Two adjusting mechanisms 1 are used to adjust two flipping mechanisms 2 relative to each other or in opposite directions. Two flipping mechanisms 2 are used to rotate two milling mechanisms 3. Two milling mechanisms 3 are used to mill both sides of the steel plate simultaneously. Two first limiting mechanisms 4 are used to limit both sides of the steel plate. Two second limiting mechanisms 5 are used to limit the top of the steel plate. Two third limiting mechanisms 6 are used to limit the bottom of the steel plate.

[0021] Specifically, the operator first uses the two-sided adjustment mechanism 1 to move the two-sided flipping mechanism 2 to a designated position. Then, the two-sided flipping mechanism 2 is used to move the two-sided milling mechanism 3 to a designated position, so that both sides of the milling mechanism 3 are in contact with the two sides of the steel plate. Next, the two-sided first limiting mechanism 4, the two-sided second limiting mechanism 5, and the two-sided third limiting mechanism 6 are moved to designated positions, so that the two-sided first limiting mechanism 4 is in contact with the two sides of the steel plate, the two-sided second limiting mechanism 5 is in contact with the top of the steel plate, and the two-sided third limiting mechanism 6 is in contact with the bottom of the steel plate. During the horizontal movement of the steel plate, the two-sided first limiting mechanism 4 limits the two sides of the steel plate, the two-sided second limiting mechanism 5 limits the top of the steel plate, and the two-sided third limiting mechanism 6 limits the bottom of the steel plate. Finally, the two-sided milling mechanism 3 is used to mill the two sides of the steel plate. There is no need to flip the steel plate, the operation is relatively simple, time-saving and labor-saving, and the processing efficiency is improved.

[0022] Please see Figure 3 In this embodiment, the adjustment mechanism 1 includes a base 11, a pad 12 is fixedly installed inside the base 11, a first motor 13 is fixedly installed on the outer wall of the base 11, and a lead screw 14 is rotatably installed inside the base 11 and on the top of the pad 12 through a first bearing. The output end of the first motor 13 is fixedly connected to one end of the lead screw 14.

[0023] Specifically, by turning on the first motor 13, the first motor 13 drives the lead screw 14 to rotate.

[0024] Please see Figure 4-6 In this embodiment, the flipping mechanism 2 includes a first chamber 21. A nut 22 is fixedly installed at the bottom of the first chamber 21. The nut 22 is threaded to the outside of the lead screw 14. The threaded hole inside the nut 22 matches the lead screw 14. Fixing plates 23 are detachably installed on the side wall of the first chamber 21 and the outside of the base 11. They are disassembled and assembled by the first bolt. A rotating shaft 24 is hinged inside the first chamber 21. A second chamber 25 is fixedly installed outside the rotating shaft 24. A hydraulic cylinder 26 is hinged together on the top of the first chamber 21 and the outer side wall of the second chamber 25.

[0025] Specifically, the lead screw 14 rotates inside the nut 22, and the nut 22 drives the first chamber 21 to move linearly to the designated position on the top of the base 11 and fix it with the first bolt. By opening the hydraulic cylinder 26, the hydraulic cylinder 26 drives the second chamber 25 to rotate around the rotating shaft 24, so as to facilitate the second limit mechanism 5 to contact the top of the steel plate.

[0026] Please see Figure 7In this embodiment, the milling mechanism 3 includes a horizontal plate 31, which is fixedly connected to the inside of the second chamber 25. A second motor 32 is fixedly installed on the inner bottom wall of the second chamber 25. A reducer 33 is fixedly installed at the output end of the second motor 32. The output end of the reducer 33 passes through the horizontal plate 31 and is detachably installed with a milling cutter 34, which is disassembled and assembled by a second bolt. Through holes are opened in the inside of the horizontal plate 31 and the side wall of the second chamber 25. A discharge hopper 35 is fixedly installed at an incline inside the two through holes.

[0027] Specifically, by turning on the second motor 32, the second motor 32 drives the reducer 33 and the milling cutter 34 to rotate. The milling cutter 34 mills one side of the steel plate, and the waste material generated can be discharged along the discharge hopper 35 when it splashes.

[0028] Please see Figure 8 In this embodiment, the first limiting mechanism 4 includes a side plate 41, which is fixedly connected to the outer side wall of the second compartment 25. A threaded rod 42 is installed inside the side plate 41. One end of the threaded rod 42 is rotatably mounted to a first limiting box 43 via a second bearing. A first limiting strip is fixedly installed on the outer side wall of the second compartment 25. The first limiting strip matches the first limiting box 43. A first limiting roller 44 is rotatably mounted inside the first limiting box 43 via a third bearing.

[0029] Specifically, by rotating the threaded rod 42, the threaded rod 42 rotates and moves linearly inside the side plate 41. The threaded rod 42 drives the first limiting box 43 and the first limiting roller 44 to move to the designated position, so that the first limiting roller 44 contacts one side of the steel plate.

[0030] Please see Figure 9 In this embodiment, the second limiting mechanism 5 includes a crossbeam 51, which is fixedly connected to the inside of the second compartment 25. A first screw jack 52 is fixedly installed on the top of the crossbeam 51. The lifting end of the first screw jack 52 passes through the crossbeam 51 and is fixedly installed with a second limiting box 53. A second limiting strip is fixedly installed on the inner side wall of the second compartment 25. The second limiting strip matches the second limiting box 53. A plurality of second limiting rollers 54 are rotatably installed inside the second limiting box 53 through a fourth bearing. The plurality of second limiting rollers 54 are evenly and equidistantly distributed.

[0031] Specifically, the first screw jack 52 drives the second limit box 53 and the second limit roller 54 to move downward, so that the second limit roller 54 comes into contact with the top of the steel plate.

[0032] Please see Figure 10In this embodiment, the third limiting mechanism 6 includes a second screw jack 61, which is fixedly connected to the inner bottom wall of the first chamber 21. A third limiting box 62 is fixedly installed on the top of the second screw jack 61. A third limiting strip is fixedly installed on the inner side wall of the second chamber 25. The third limiting strip matches the third limiting box 62. Multiple third limiting rollers 63 are rotatably installed inside the third limiting box 62 through a fifth bearing. The multiple third limiting rollers 63 are evenly and equidistantly distributed.

[0033] Specifically, the second screw jack 61 drives the third limit box 62 and the third limit roller 63 to move upward, so that the third limit roller 63 comes into contact with the bottom of the steel plate.

[0034] The working principle of the above embodiments is as follows: First, the operator activates the two first motors 13. The first motors 13 drive the two lead screws 14 to rotate inside the two nuts 22. The nuts 22 move the two first chambers 21 linearly to the designated position on top of the two bases 11, where they are secured with the two first bolts. Then, the two hydraulic cylinders 26 are activated. The hydraulic cylinders 26 drive the two second chambers 25 to rotate around the two rotating shafts 24, moving the two milling cutters 34 to the designated position, ensuring the milling cutters 34 contact both sides of the steel plate. Next, the two threaded rods 42 are rotated, moving linearly inside the two side plates 41. The threaded rods 42 move the two first limit boxes 43 and the two first limit rollers 44 to the designated position, ensuring the first limit rollers 44 contact both sides of the steel plate. Finally, the two first screw jacks 52 drive the two second... The limiting box 53 and the two second limiting rollers 54 on both sides move downwards, so that the two second limiting rollers 54 on both sides contact the top of the steel plate. The two second screw jacks 61 on both sides drive the two third limiting boxes 62 and the two third limiting rollers 63 on both sides to move upwards, so that the two third limiting rollers 63 on both sides contact the bottom of the steel plate. During the horizontal movement of the steel plate, the two first limiting rollers 44 on both sides limit the two sides of the steel plate, the two second limiting rollers 54 on both sides limit the top of the steel plate, and the two third limiting rollers 63 on both sides limit the bottom of the steel plate. Finally, the two second motors 32 on both sides are turned on, which drive the two reducers 33 on both sides and the two milling cutters 34 on both sides to rotate. The two milling cutters 34 on both sides mill the two sides of the steel plate. When the waste material splashes out, it can be discharged along the two discharge hoppers 35 on both sides without the need to flip the steel plate. The operation is relatively simple, saving time and effort and improving processing efficiency.
