Description

Technical Field

[0001] This utility model relates to the field of spiral steel pipe production technology, and more specifically, to a milling machine for a spiral steel pipe production line. Background Technology

[0002] Spiral steel pipe, also known as spiral welded pipe, is a pipe made by rolling steel strip (usually low carbon steel or low alloy structural steel) into a spiral shape at room temperature and then welding it by double-sided submerged arc welding technology. Before welding, the edges of the steel strip need to be processed by a milling machine to facilitate subsequent welding operations.

[0003] Traditional milling machines used in spiral welded steel pipe production lines have the following shortcomings: During operation, the steel strip is first placed above the milling machine. Then, the milling cutter head contacts the edge of the steel strip and moves in a straight line along it to achieve precise bevel processing. During milling, air jets are typically placed next to the milling cutter head to cool the milling area. However, during air cooling, the contact between the milling cutter head and the steel strip generates a large amount of debris. The high-speed airflow from the air jets disperses this debris, causing it to spread outwards from the milling area. Due to friction between the debris and the steel strip surface, some debris may adhere to the surface and move with the strip, affecting the milling quality and subsequent processes. Therefore, improvements are needed. Utility Model Content

[0004] In order to overcome the shortcomings of the existing technology, this utility model provides a milling machine for spiral steel pipe production line, which has the advantage of cleaning up debris.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a milling machine for a spiral steel pipe production line, comprising a base, side plates fixedly installed on both sides of the base, a milling mechanism provided on the front side of the base, a top plate fixedly installed above the side plates, blocks fixedly installed on the front sides of both ends of the top plate, a horizontal plate fixedly installed between the inner sides of the blocks, a through groove opened on the inner side of the horizontal plate, an air pump evenly fixedly installed above the horizontal plate, a fixing mechanism provided above the top plate, the fixing mechanism comprising a platform located below the top plate, two protrusions fixedly installed on the outer side of the platform, a round shaft fixedly installed on the inner side of the protrusions, a rectangular block fixedly installed on the outer side of the round shaft, a fixing ring fixedly installed on the outer side of the rectangular block, an air jet head fixedly installed on the outer front end of the rectangular block, and a rubber air pipe extending to the rear end of the air jet head fixedly installed below the air pump.

[0009] As a preferred embodiment of this utility model, an induction plate is fixedly installed on the inner side of the machine body, and infrared emitters are uniformly fixedly installed on the outer side of the base, with the infrared emitters corresponding to the air pump.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] like Figures 1 to 8As shown, this utility model provides a milling machine for a spiral steel pipe production line, including a base 1, side plates 2 fixedly installed on both sides of the base 1, a milling mechanism 3 provided on the front side of the base 1, a top plate 4 fixedly installed above the side plates 2, blocks 8 fixedly installed on the front sides of both ends of the top plate 4, a horizontal plate 9 fixedly installed between the inner sides of the blocks 8, a through groove 10 opened on the inner side of the horizontal plate 9, an air pump 11 evenly fixedly installed above the horizontal plate 9, a fixing mechanism 6 provided above the top plate 4, the fixing mechanism 6 including a platform 603 located below the top plate 4, two protrusions 606 fixedly installed on the outer side of the platform 603, a round shaft 607 fixedly installed on the inner side of the protrusions 606, a rectangular block 608 fixedly installed on the outer side of the round shaft 607, a fixing ring 609 fixedly installed on the outer side of the rectangular block 608, an air nozzle 610 fixedly installed on the outer front end of the rectangular block 608, and a rubber air pipe 611 extending to the rear end of the air nozzle 610 fixedly installed below the air pump 11.

[0026] In use, the steel strip is first placed above the placement plate 5. Then, the fixing mechanism 6 is activated by the controller 7, causing the fixing mechanism 6 to move downwards to fix the steel strip. Then, the machine body 302 moves above the linear module 301, and the cutter head 304 is brought into contact by the robotic arm 303. At this time, the infrared emitter 12 emits a light signal to the surface of the sensing plate 305. The sensing plate 305 receives the infrared signal and converts the light signal into an electrical signal using the built-in infrared receiving diode, filter, and amplifier. The electrical signal of the sensing plate 305 is processed by the PLC, and then the air pump 11 is controlled by the controller 7 to run. The air pump 11 sprays air into the milling area through the rubber air tube 611 and the air nozzle 610, spraying the debris from left to right into the interior of the groove 13. When the machine body 302 continues to move, the light signal emitted by the infrared emitter 12 cannot be released to the surface of the sensing plate 305, thereby controlling the air pump 11 to stop running.

[0027] By setting an air jet head 610 on the outside of the table body 603, the air jet head 610 cleans the milling area from left to right. Compared with the traditional milling machine for spiral steel pipe production line, this milling machine for spiral steel pipe production line uses the air jet head 610 to follow the cutter head 304 to spray air into the milling area, so that the generated debris can be sprayed from left to right into the interior of the groove 13. This can effectively prevent debris from accumulating on the surface of the steel strip and affecting subsequent processing. At the same time, the hydraulic cylinder 601 also cools down the cutter head 304, making it easier to use.

[0028] The base 1 has a placement plate 5 fixedly installed on its upper part. The front surface of the base 1 has a groove 13. A collection box 14 is evenly installed inside the groove 13. A round rod 16 is fixedly installed on the inner side of the collection box 14. Inclined grooves 15 are opened on the inner sides of both ends of the collection box 14.

[0029] The jet head 610 blows a large amount of debris from left to right into the interior of the groove 13, causing the debris to fall into the interior of the collection box 14. By setting the inclined groove 15 on the inner side of the collection box 14, the debris is prevented from falling onto the surface of the collection box 14 and making it difficult to clean. When it is necessary to clean the debris in the collection box 14, simply pull the round rod 16 to pull the collection box 14 out from the groove 13, and then directly pour out the debris, thus completing the cleaning of the debris.

[0030] The large amount of debris generated during milling is collected by the collection box 14. The debris can be cleaned by pulling the round rod 16 to remove the collection box 14. Compared with the traditional milling machine for spiral steel pipe production line, this milling machine for spiral steel pipe production line collects debris by installing multiple collection boxes 14 inside the groove 13, which facilitates the subsequent cleaning of debris and makes it easy to use.

[0031] The milling mechanism 3 includes a linear module 301 fixedly installed on the front side of the base 1, a body 302 is arranged above the linear module 301, a robotic arm 303 is movably installed above the body 302, and a cutter head 304 is rotatably installed at the front end of the robotic arm 303.

[0032] The machine body 302 moves above the linear module 301, and the tilt angle of the cutter head 304 is adjusted by the robotic arm 303 to perform milling operations on the steel strip.

[0033] The fixing mechanism 6 also includes a hydraulic cylinder 601 fixedly installed above the top plate 4, an air pump 11 corresponding to the hydraulic cylinder 601, a telescopic rod 602 fixedly installed below the hydraulic cylinder 601, a platform 603 fixedly connected below the telescopic rod 602, a vertical rod 604 fixedly installed below the platform 603, and a fixing seat 605 fixedly installed below the vertical rod 604.

[0034] Start the hydraulic cylinder 601, which drives the telescopic rod 602 to move downward, causing the fixed seat 605 to move downward with the platform 603 to fix the steel strip.

[0035] The inner side of the body 302 is fixedly installed with a sensor plate 305, and the outer side of the base 1 is uniformly fixed with infrared emitters 12, which correspond to the air pump 11.

[0036] The sensor board 305 receives infrared signals and has built-in infrared receiving diodes, filters and amplifiers to convert the light signals into electrical signals. The PLC processes the electrical signals of the sensor board 305 and then controls the air pump 11 to run through the controller 7, so that the air pump 11 sprays air onto the milled area through the rubber air tube 611 and the air nozzle 610.

[0037] The controller 7 is fixedly installed on the left side of the base 1. The controller 7 is electrically connected to the infrared transmitter 12 and the air pump 11.

[0038] The controller 7 controls the operation of the air pump 11, which sprays air through the rubber air tube 611 and the air nozzle 610 to the milled area, spraying the debris from left to right into the interior of the groove 13.

[0039] There are nine hydraulic cylinders 601, and three hydraulic cylinders 601 form a group.

[0040] By dividing the hydraulic cylinder 601 into three groups, it is convenient to fix materials of different lengths, making it easy to use.

[0041] Working principle and usage process of this utility model:

[0042] In use, the steel strip is first placed above the placement plate 5. Then, the fixing mechanism 6 is activated by the controller 7, causing the fixing mechanism 6 to move downwards to fix the steel strip. Then, the machine body 302 moves above the linear module 301, and the cutter head 304 is brought into contact by the robotic arm 303. At this time, the infrared emitter 12 emits a light signal to the surface of the sensing plate 305. The sensing plate 305 receives the infrared signal and converts the light signal into an electrical signal using the built-in infrared receiving diode, filter, and amplifier. The electrical signal of the sensing plate 305 is processed by the PLC, and then the air pump 11 is controlled by the controller 7 to run. The air pump 11 sprays air into the milling area through the rubber air tube 611 and the air nozzle 610, spraying the debris from left to right into the interior of the groove 13. When the machine body 302 continues to move, the light signal emitted by the infrared emitter 12 cannot be released to the surface of the sensing plate 305, thereby controlling the air pump 11 to stop running.

[0043] The jet head 610 blows a large amount of debris from left to right into the interior of the groove 13, causing the debris to fall into the interior of the collection box 14. By setting the inclined groove 15 on the inner side of the collection box 14, the debris is prevented from falling onto the surface of the collection box 14 and making it difficult to clean. When it is necessary to clean the debris in the collection box 14, simply pull the round rod 16 to pull the collection box 14 out from the groove 13, and then directly pour out the debris, thus completing the cleaning of the debris.
