Description

Technical Field

[0001] The invention belongs to the technical field of heating tube processing, in particular to an explosion-proof electric heating tube processing device. Background Art

[0002] ‌Explosion-proof electric heating tube is a heating device specially used in dangerous places. Its main function is to provide safe and reliable heating function in special environments such as flammable, explosive, corrosive, etc.‌

[0003] The design and manufacture of explosion-proof electric heating tubes use explosion-proof materials to ensure safe use in flammable and explosive environments. Its working principle is to convert thermal energy into heat through electrical energy. The heating element is usually made of nickel-chromium alloy, stainless steel and other materials. These materials have good heat resistance, thermal conductivity and insulation, which can ensure the efficiency and safety of the heating process.

[0004] When making the electric heating tube, first of all, the selected stainless steel empty tube needs to be cut. After the empty tube is cut, the empty tube that needs to be straightened is put into the straightening machine for straightening, and then the empty tube is cleaned, and then the resistance wire is made into a spiral shape by using a wire winding machine, and then the resistance wire and the lead rod are welded by an electric welding machine, and then magnesium oxide powder is added to the empty tube, and then the electric heating tube is reduced by a tube reduction machine, and then the two ends of the electric heating tube are cut, and the lead rod is exposed, and then annealing is performed. After the annealing is completed, the electric heating tube is bent into the required shape, and then glue is applied to seal it, and a final inspection is performed;

[0005] However, since the pipes used to make the electric heating tubes are stainless steel empty tubes, some of the stainless steel empty tubes are in a bent state and therefore need to be straightened. When straightening the empty tubes, the empty tubes need to be squeezed. When the empty tubes are squeezed, they will become deformed and dented, thus affecting the quality of the electric heating tubes. Summary of the invention

DETAILED DESCRIPTION

[0053] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0057] A rotating shaft 22 is fixedly mounted on the end of the two straightening rollers 2 away from the feed pipe 11, and the rotating shaft 22 extends to the side away from the feed pipe 11 and is rotatably mounted on the chassis 1; a first motor 12 is mounted on the side wall of the chassis 1, and the first motor 12 is connected to the rotating shaft 22 below through a coupling;

[0058] The two rotating shafts 22 are fixedly connected to a gear 13 on one side close to the first motor 12, and the two gears 13 are meshed with each other;

[0059] The two straightening rollers 2 are both equipped with straightening components, and the straightening components are used to straighten the empty tube 15 of the processed electric heating tube;

[0060] A group of first mounting grooves is provided on the outer ring surfaces of the two straightening rollers 2, and the group of first mounting grooves includes two long grooves 23; the two long grooves 23 are provided on the straightening roller 2, and the two long grooves 23 are mirror-imaged with the center of the straightening roller 2 as the dividing line;

[0061] A discharge trough 14 is provided on the chassis 1 below the feed pipe 11 ; a push assembly is installed at the bottom of the inner cavity of the chassis 1 at the position of the discharge trough 14 , and the push assembly is used to push out the straightened empty tube 15 .

[0062] In this embodiment, the straightening assembly includes a straightening wheel 3;

[0063] The two long grooves 23 are rotatably connected with evenly arranged straightening wheels 3 through a rotating rod; an annular straightening groove 31 is formed on the outer ring surface of each straightening wheel 3, and the cross section of the annular straightening groove 31 is semicircular;

[0064] In the initial state, one of the long grooves 23 on the two straightening rollers 2 corresponds to each other, and the straightening wheels 3 in the long grooves 23 also correspond to each other. The annular straightening grooves 31 on the two corresponding straightening wheels 3 will form a complete circular groove, and the circular groove corresponds to the feed pipe 11. At the same time, the diameter of the formed circular groove is the same as the diameter of the empty pipe 15, and is used to straighten the empty pipe 15;

[0065] On the outer ring surface of each straightening wheel 3, there are tooth grooves 32 evenly arranged at both sides of the annular straightening groove 31; a cylindrical groove 24 is opened in the middle of the two straightening rollers 2, and the cylindrical groove 24 is connected to the long groove 23; a worm 25 is rotatably connected in the two cylindrical grooves 24, and the worm 25 is meshed with the tooth grooves 32 on the plurality of straightening wheels 3;

[0066] The side of the worm 25 close to the drum 21 extends out from the drum 21; the second motor 26 is fixedly installed on the side where the two worms 25 extend out of the drum 21, and the second motor 26 is fixedly installed on the side wall of the chassis 1;

[0067] A driven disc 4 is fixedly mounted on the rotating shaft 22 close to the pusher assembly, and the driven disc 4 corresponds to the straightening roller 2 on the left side;

[0068] A set of first straightening parts is welded on the circumference of the driven disc 4, and the set of first straightening parts includes two straightening rods 41, which are mirror-imaged with the center of the driven disc 4 as the dividing line;

[0069] In the initial state, the two straightening rods 41 extend to one side of the rotating drum 21 and are located on the opposite side of the two long grooves 23. At the same time, the straightening rods 41 pass through the annular straightening groove 31 on the straightening wheel 3 in the long groove 23. The diameter of the two straightening rods 41 is the same as the inner diameter of the empty tube 15 to be straightened.

[0070] Specifically, when the empty pipe 15 is to be straightened, the second motor 26 is started first, and then the empty pipe 15 to be straightened is put into the feed pipe 11, and then the empty pipe 15 is pushed to move into the inside of the chassis 1. Since the straightening wheels 3 close to each other on the two straightening rollers 2 in the initial state correspond to each other, and since the circular groove formed by the annular straightening grooves 31 on the two straightening wheels 3 corresponds to the feed pipe 11, the empty pipe 15 entering the chassis 1 will gradually extend into the circular groove formed by the two opposite straightening wheels 3 on the two straightening rollers 2. Since the worm 25 is meshed with the tooth grooves 32 provided on the straightening wheel 3, when the two second motors 26 rotate, the two worms 25 will be driven to rotate, and the two The worm 25 will drive the meshing straightening wheel 3 to rotate. At this time, the straightening wheel 3 located above the empty tube 15 rotates counterclockwise, and the straightening wheel 3 located below the empty tube 15 rotates clockwise. When the empty tube 15 contacts the straightening wheels 3 rotating on the upper and lower sides, the empty tube 15 will be squeezed into the annular straightening grooves 31 on the two straightening wheels 3. At the same time, the straightening wheels 3 rotating on the upper and lower sides will push the empty tube 15 to move toward the side of the driven disk 4. The moving empty tube 15 will pass through multiple pairs of straightening wheels 3 corresponding to each other. When the empty tube 15 passes through the annular straightening grooves 31 opened by multiple pairs of straightening wheels 3, the empty tube 15 can be straightened under the limitation of multiple pairs of straightening wheels 3 and the annular straightening grooves 31.

[0071] More specifically, since the two straightening rods 41 extend to one side of the rotating drum 21 and are located on the opposite side of the two long grooves 23, and the straightening rods 41 pass through the annular straightening grooves 31 on the straightening wheels 3 in the long grooves 23, when the empty tube 15 moves to the position of the straightening wheels 3, the straightening rods 41 will be inserted into the empty tube 15, and when the relative straightening wheels 3 drive the empty tube 15 to move toward one side of the driven disk 4, the empty tube 15 will move along the straightening rods 41, and the straightening rods 41 will gradually be inserted into the empty tube 15. In the process of the straightening rods 41 being inserted into the empty tube 15, the straightening rods 41 can first straighten the empty tube 15 to make the empty tube 15 in a straightened state, and then the empty tube 15 moving along the straightening rods 41 will move to the two relative straightening wheels 3. Between the straightening wheels 3, the rotating straightening wheels 3 will push the empty tube 15 to move along the straightening rods 41, and at the same time, multiple pairs of straightening wheels 3 will squeeze and straighten the outer ring of the empty tube 15. Since the straightening rods 41 are inserted into the empty tube 15 at this time, the straightening rods 41 inserted into the empty tube 15 will fill the inner cavity of the empty tube 15. Therefore, when the straightening wheels 3 squeeze and straighten the empty tube 15, deformation and depression of the empty tube 15 can be avoided. At the same time, when the empty tube 15 is gradually inserted into the straightening rods 41, if the empty tube 15 itself is depressed, the straightening rods 41 gradually inserted into the empty tube 15 can lift up the depressed position of the empty tube 15. The existing straightening machine can only straighten the surface of the empty tube 15, and cannot straighten the depressed part inside the empty tube 15.

[0072] Furthermore, when the empty tube 15 moves to the position of the driven disk 4, the empty tube 15 will contact the driven disk 4, and then the first motor 12 will be controlled to rotate, and the first motor 12 will drive the lower rotating shaft 22 to rotate. Since the two rotating shafts 22 are fixedly connected with mutually meshing gears 13, when the lower rotating shaft 22 rotates, the gear 13 will drive the upper rotating shaft 22 to rotate in the opposite direction, and the rotation angle is the same. In the process of the two rotating shafts 22 rotating, the two straightening rollers 2 will also be driven to rotate. In the process of the two straightening rollers 2 rotating, the straightening wheels 3 on the straightening rollers 2 will be driven to rotate. In the process of the straightening wheel 3 following the rotation of the straightening roller 2, the straightening wheels 3 originally relative to each other will gradually separate, and at the same time, in the process of the rotation of the rotating shaft 22, the driven disk 4 will be driven to rotate, and the rotating driven disk 4 will drive the straightening rod 41 to rotate, so the straightening rod 41 will drive the empty tube 15 to rotate with the rotating straightening wheel 3. After the straightening roller 2 rotates 180 degrees, the straightening wheels 3 originally relative to each other will rotate to the opposite side of the two straightening rollers 2, and at the same time, the straightening wheels 3 in the other long grooves 23 on the two straightening rollers 2 will correspond to each other, and then the empty tube 15 can continue to be put into the feeding pipe 11 for straightening;

[0073] Furthermore, after the straightening rod 41 rotates one hundred and eighty degrees following the straightening roller 2, the straightening rod 41 and the empty tube 15 are located at the bottom. Then, the pushing assembly is controlled to start, and the empty tube 15 on the straightening rod 41 can be pushed down. Then, the above operation is repeated to continuously straighten the empty tube 15.

[0074] Embodiment 2: The outer ring surface of the rotating shaft 22 close to the pusher assembly is provided with evenly arranged slide grooves 221; the driven disc 4 is sleeved on the rotating shaft 22 and is slidably connected with the slide grooves 221;

[0075] The outer ring surface of the driven plate 4 is provided with evenly arranged thread grooves 401, and the thread grooves 401 extend into the slide groove 221; each of the thread grooves 401 is threadedly engaged with a hexagon socket bolt, and the hexagon socket bolt is used to lock and fix the driven plate 4;

[0076] Each of the straightening rods 41 includes a threaded rod 42 and a threaded barrel 43 ; the threaded rods 42 are welded on the circumference of the driven disc 4 ; each of the threaded rods 42 is inserted into the threaded barrel 43 and threadedly engaged with the threaded barrel 43 .

[0077] In this embodiment, multiple groups of second mounting grooves are provided on the outer ring surfaces of the two straightening rollers 2, and the multiple groups of second mounting grooves and one group of first mounting grooves are evenly arranged on the outer ring surfaces of the straightening rollers 2;

[0078] Each group of the second installation grooves also includes two long grooves 23, and the two long grooves 23 of each group of the second installation grooves are mirror-imaged with the center of the straightening roller 2 as the dividing line;

[0079] Each group of the second installation grooves is also rotatably installed with evenly arranged straightening wheels 3; each group of the straightening wheels 3 in the second installation grooves is also provided with an annular straightening groove 31;

[0080] The diameter of the annular straightening groove 31 on the straightening wheel 3 in each group of the second installation grooves is different, and the diameter of the annular straightening groove 31 on the straightening wheel 3 in each group of the first installation grooves is also different, and the annular straightening grooves 31 with different diameters correspond to the empty pipes 15 with different diameters;

[0081] The driven disk 4 is welded with multiple sets of second straightening members, and the multiple sets of second straightening members and one set of first straightening members are evenly arranged on the driven disk 4, and each set of second straightening members also includes two straightening rods 41, and are mirror-imaged with the center of the driven disk 4 as the dividing line;

[0082] The diameter of each group of the second straightening members is different, and is also different from the diameter of the first straightening members of the group, and the straightening rods 41 all pass through the annular straightening grooves 31 on the straightening wheel 3 in the corresponding long grooves 23, and the diameter of the straightening rods 41 passing through the annular straightening grooves 31 of different diameters is the same as the inner cavity diameter of the empty tube 15 corresponding to the annular straightening grooves 31;

[0083] Specifically, when it is necessary to straighten the empty tubes 15 of different lengths, the hexagon socket bolt in the threaded groove 401 is loosened with an hexagon socket wrench. When the hexagon socket bolt no longer abuts against the slide groove 221, the length of the empty tube 15 can be straightened as needed, the driven disk 4 is pushed to slide on the rotating shaft 22, and the position of the driven disk 4 is determined, and then the hexagon socket bolt is tightened, so that the driven disk 4 can be locked on the rotating shaft 22. Since the straightening rod 41 is composed of the threaded rod 42 and the threaded cylinder 43, the threaded cylinder 43 can be rotated as needed to straighten the length of the empty tube 15, so that the overall length of the straightening rod 41 can be adjusted, so that the adjusted length of the straightening rod 41 is adapted to the empty tube 15 that needs to be straightened.

[0084] When it is necessary to straighten empty pipes 15 of different diameters, firstly, according to the diameter of the empty pipe 15 to be straightened, straightening wheels 3 of the same diameter are selected, and the first motor 12 is controlled to drive the rotating shaft 22 to rotate, and the rotating shaft 22 will drive the straightening roller 2 to rotate, and the straightening roller 2 will drive the straightening wheels 3 in the plurality of second mounting grooves to rotate. When the straightening wheels 3 corresponding to the diameter of the empty pipe 15 on the two straightening rollers 2 rotate to the opposite side, the straightening rollers 2 are controlled to stop rotating, and then the empty pipes 15 of different diameters can be straightened;

[0085] By setting up straightening wheels 3 installed in multiple groups of second mounting grooves, and the straightening wheels 3 in each group of second mounting grooves correspond to one type of empty pipe 15, when it is necessary to straighten empty pipes 15 of different diameters, the corresponding straightening wheels 3 can be selected according to the diameter of the empty pipe 15, so that there is no need to adjust the position of the straightening wheel 3, and there is no need to remove the straightening wheel 3 and replace it with a new one, so that empty pipes 15 of different diameters can be straightened, and at the same time, by adjusting the position of the driven disk 4, empty pipes 15 of different lengths can be straightened. Therefore, empty pipes 15 of different lengths can be straightened, and empty pipes 15 of different diameters can also be straightened, thereby improving the practicality of the straightening machine.

[0086] Embodiment 3: The pusher assembly includes a conveyor belt 5; the conveyor belt 5 is located below the driven disk 4 and is driven by a third motor 54, and the third motor 54 is installed on the chassis 1;

[0087] A push block 51 is fixedly connected to the top of the conveyor belt 5, and the push block 51 is made of rubber material; the push block 51 is initially located on the right side of the driven disk 4; the push block 51 is located below the straightening rod 41, and when the conveyor belt 5 drives the push block 51 to move, the push block 51 will push the empty tube 15 sleeved on the straightening rod 41 to move;

[0088] In this embodiment, the right side of the push block 51 is fixedly connected to a uniformly arranged first brush 52 on the conveyor belt 5;

[0089] In this embodiment, a top plate is provided on the top of the straightening roller 2 away from the conveyor belt 5, and the top plate is fixedly connected to the chassis 1; the bottom of the top plate is fixedly connected to uniformly arranged second brushes 53;

[0090] Specifically, when the straightening rod 41 drives the empty tube 15 to rotate to the bottom, the third motor 54 drives the conveyor belt 5 to rotate one circle. During the rotation of the conveyor belt 5, the push block 51 will be driven to pass under the driven plate 4. Finally, the push block 51 will push the empty tube 15 sleeved on the straightening rod 41 to move, and at the same time control the straightening wheel 3 to rotate. The rotating straightening wheel 3 can push the empty tube 15 to gradually detach from the straightening rod 41, and finally move out of the discharge chute 14.

[0091] More specifically, the conveyor belt 5 will drive the first brush 52 to move at the same time. The moving first brush 52 can clean the lowest straightening wheel 3, thereby avoiding the presence of impurities on the straightening wheel 3, which will affect the straightening process of the empty tube 15; at the same time, during the rotation of the uppermost straightening wheel 3, it will contact the second brush 53. The second brush 53 can also rotate to the uppermost straightening wheel 3 for cleaning, thereby avoiding the straightening wheel 3 from being attached with impurities, which will cause marks on the empty tube 15 when the empty tube 15 is straightened.

[0092] Embodiment 4: The end of the threaded barrel 43 away from the driven disc 4 is spherical; a rubber block 44 is fixedly connected to the spherical surface of the threaded barrel 43, and the rubber block 44 is made of elastic rubber material; a cleaning layer 45 is fixedly connected to the outer circumferential surface of the threaded barrel 43 on the right side of the rubber block 44, and the cleaning layer 45 is a cloth layer;

[0093] Specifically, since the rubber block 44 is fixedly connected to the threaded tube 43, when the straightening rod 41 is inserted into the empty tube 15, the rubber block 44 will first squeeze into the empty tube 15. As the empty tube 15 gradually moves along the straightening rod 41, the rubber block 44 will move inside the empty tube 15. The moving rubber block 44 can gradually push out impurities in the empty tube 15. At the same time, the cleaning layer 45 fixedly connected to the straightening rod 41 can wipe and clean the inner cavity of the empty tube 15, thereby pre-cleaning the inner cavity of the empty tube 15.
