Description

Technical Field

[0001] This invention relates to the field of flange assembly technology, specifically to auxiliary tooling for large-diameter flange assembly machines. Background Technology

[0002] A flange, also called a flange plate or flange, is a part used to connect shafts, for connecting pipe ends; flanges are also used on equipment inlets and outlets for connecting two pieces of equipment, such as gearbox flanges. A flange connection or flange joint refers to a detachable connection consisting of a flange, gasket, and bolts forming a combined sealing structure. Pipe flanges refer to flanges used for piping in pipeline installations, while equipment flanges refer to the inlet and outlet flanges of the equipment. Flanges have holes, and bolts are used to tightly connect two flanges. A gasket is used for sealing between flanges. Flanges are classified as threaded flanges, welded flanges, and clamp flanges. Flanges are always used in pairs; threaded flanges can be used for low-pressure pipelines, while welded flanges are used for pressures above four kilograms. A gasket is placed between two flange plates, and then they are tightened with bolts. Flanges of different pressure ratings have different thicknesses, and the bolts used also differ. Pumps and valves, when connected to pipelines, are also made with corresponding flange shapes, also known as flange connections. Any connecting part that uses bolts to connect and seal two planes is generally called a "flange," such as the connection of ventilation ducts. These parts can be called "flange-type parts." However, if this connection is only a part of a device, such as the connection between a flange and a water pump, it's not appropriate to call the water pump a "flange-type part." Smaller items like valves can be called "flange-type parts." A flange connection involves fixing two pipes, fittings, or equipment to a flange plate, placing a gasket between the two flange plates, and then tightening them together with bolts. Some fittings and equipment already have built-in flanges, which also fall under the category of flange connections. Flange connections are an important connection method in pipeline construction. Flange connections are convenient to use and can withstand higher pressures. In industrial pipelines and in homes, where pipe diameters are small and pressure is low, flange connections are not commonly seen. However, in a boiler room or production site, flange-connected pipes and equipment are ubiquitous. The forging process generally consists of the following steps... The process involves selecting high-quality steel billets, heating, forming, and cooling after forging. Forging methods include free forging, die forging, and mold forging. During production, different forging methods are selected based on the size of the forging and the production batch. Free forging has low productivity and large machining allowance, but the tools are simple and versatile, making it widely used for forging simple single-piece or small-batch forgings. Free forging equipment includes air hammers, steam-air hammers, and hydraulic presses, suitable for small, medium, and large forgings, respectively. Die forging has high productivity, simple operation, and is easily mechanized and automated. Die forgings have high dimensional accuracy, small machining allowance, and a more rational fiber structure distribution, further improving the service life of parts.

[0003] Large-diameter flange assembly machines are crucial equipment on medium and large-diameter production lines, used for positioning and assembling flanges of DN200-DN500 pipes. During assembly, a flange gasket is placed inside the flange, close to the clamping jaws, to control the flange indentation and ensure assembly accuracy. However, due to an unreasonable clamping jaw design, flange gaskets cannot be placed when assembling DN200 and DN250 pipe flanges (see attached image). Figure 1 However, there are a large number of large-diameter pipe flanges (DN200 and DN250). In actual use, the flange indentation can only be controlled by measuring and adjusting each flange individually with a tape measure during assembly. This makes it difficult to guarantee assembly accuracy and greatly affects flange assembly efficiency. Therefore, we propose a new type of equipment to solve the above problems.

[0028] 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 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.

[0029] Please see Figure 1-6Auxiliary tooling for a large-diameter flange assembly machine, including a base plate 1, is characterized by: a transverse moving assembly 2 inserted into one side of the base plate 1; a vertical moving assembly 3 inserted inside the transverse moving assembly 2; a pusher assembly 4 inserted into one end of the vertical moving assembly; and an infrared sensor receiver 5 inserted inside the pusher assembly 4. The infrared sensor receiver 5 is an infrared receiver, a device capable of receiving infrared signals and independently completing the process from infrared reception to output, compatible with TTL electrical frequency signals. Its size is similar to a common plastic-encapsulated transistor, suitable for various infrared remote control and infrared data transmission applications. It has a built-in dedicated IC for wide-angle and long-distance connections, strong anti-interference capabilities, and can withstand environmental interference. It operates at low voltage. A fixing assembly 6 is inserted inside the base plate 1.

[0030] The lateral moving assembly 2 is connected to the equipment base plate 1 and is driven by the motor A202 to rotate the threaded column A203. The threaded column A203 is connected to the moving seat 204, which allows the moving seat 204 to move laterally. The lateral movement of the moving seat 204 enables automated alignment of the equipment, which is convenient to operate, saves time, and eliminates the need for manual handling, greatly reducing the consumption of human resources.

[0031] The vertical moving assembly 3 is connected to the moving base 204 and driven by the motor B303. The moving base plate 301 is connected to the moving base 204. The motor B303 is fixed to the moving base 204 by the bolt A302, which allows the gear 304 connected to the motor B303 to rotate. The gear 304 meshes with the gear rack 305, which allows the gear rack 305 to move up and down, facilitating the calibration of the equipment height.

[0032] The push tube assembly 4 is connected to the gear rack 305 and driven by the motor C404. The connecting base plate 401 is connected to the gear rack 305. The vertical movement assembly 3 allows the gear rack 305 to move the push tube assembly up and down, while the horizontal movement assembly 2 allows the push tube assembly 4 to move left and right. The motor C404 is connected to the push tube threaded column 403, causing it to rotate. The connecting base plate 401 is connected to the tube seat 402, which is made of alloy steel. Alloy steel, in addition to iron and carbon, contains other alloying elements. It is an iron-carbon alloy formed by adding appropriate amounts of one or more alloying elements to ordinary carbon steel. Depending on the added elements and appropriate processing techniques, special properties such as high strength, high toughness, wear resistance, corrosion resistance, low temperature resistance, high temperature resistance, and non-magnetic properties can be obtained. The connecting pipe is placed on the pipe seat 402, and the pusher thread column 403 rotates and pushes the connecting pipe on the pipe seat 402 forward. The motor C404 is limited by the fixed seat 405, and the connecting rod 406 moves along the moving track of the fixed seat 405.

[0033] The fixed assembly 6 is connected to the equipment base plate 1 and driven by motor D602. The threaded post B603 connected to D602 rotates, and the threaded post B603 connects to the mounting bracket 604. The contact point between the mounting bracket 604 and the flange 608 is made of nitrile rubber. Nitrile rubber is a copolymer of acrylonitrile and butadiene monomers, mainly produced by low-temperature emulsion polymerization. It has excellent oil resistance, high wear resistance, good heat resistance, and strong adhesion. Its disadvantages include poor low-temperature resistance, poor ozone resistance, poor insulation performance, and slightly lower elasticity. Nitrile rubber is mainly used to manufacture oil-resistant rubber products; the higher the acrylonitrile content, the better the oil resistance, but the cold resistance decreases accordingly. It can be used for extended periods in air at 120°C or in oil at 150°C. Furthermore, it has good water resistance, airtightness, and excellent adhesion. Widely used in the manufacture of various oil-resistant rubber products, including oil-resistant gaskets, washers, sleeves, flexible packaging, flexible tubing, printing and dyeing rollers, and cable adhesive materials, it has become an indispensable elastic material in the automotive, aerospace, petroleum, and photocopying industries. Its rubber sealing gasket 3 utilizes the excellent oil resistance of nitrile rubber polymers. In a typical NBR structure, the trans group accounts for approximately 78%. Due to the presence of cyano groups in the NBR molecular chain structure, its oil resistance (such as resistance to mineral oils, liquid fuels, animal and vegetable oils, and solvents) is superior to that of natural rubber, chloroprene rubber, and styrene-butadiene rubber. Compared to other rubbers, NBR has a wider operating temperature range, with a long-term operating temperature of 120℃. NBR also exhibits excellent low-temperature resistance, with a minimum glass transition temperature of -55℃, making it more suitable for fixed flange applications. Nitrile rubber polymers are particularly suitable for various working environments. The mounting bracket 604 can be moved up and down by rotating the threaded column B603. Notably, another mounting bracket 604 is located opposite to the mounting bracket 604 to secure the flange 608. An infrared positioner 605 is installed within the mounting bracket 604, corresponding to the infrared sensor receiver 5. This infrared positioner 605 is an infrared positioning device, widely used in various sheet metal cutting and forming machines, stone machinery, woodworking machinery, metal saws, and packaging machinery for tool setting and line laying. It produces a clear and bright red line, is compact, easy to adjust, easy to install, and stable and reliable, significantly improving work efficiency. We can also provide an integrated laser-assisted positioning light with a built-in power supply for added convenience. The equipment base 601 has a fixing bolt 606 inside, which can be used to fix the gasket 607 and the flange 608. A flange is also called a flange plate or flange. A flange is a part used to connect shafts, for connecting pipe ends; flanges are also used on equipment inlets and outlets for connecting two pieces of equipment, such as a reducer flange. A flange connection or flange joint refers to a detachable connection consisting of a flange, gasket, and bolts connected together as a combined sealing structure.Pipe flanges refer to flanges used for piping in pipeline systems, and on equipment, they refer to the inlet and outlet flanges. Flanges have holes, and bolts are used to tightly connect two flanges. A gasket is used for sealing between flanges. Flanges are classified as threaded flanges, welded flanges, and clamp flanges. Flanges are always used in pairs. Low-pressure pipelines can use threaded flanges, while welded flanges are used for pressures above four kilograms. A gasket is placed between the two flange plates, and then they are tightened with bolts. Flanges of different pressure ratings have different thicknesses, and the bolts used for them also differ. When pumps and valves are connected to pipelines, these parts of the equipment are also made into corresponding flange shapes, which is also called flange connection. Any connecting parts that use bolts to connect and seal the perimeter of two planes are generally called "flanges," such as the connection of ventilation ducts; these parts can be called "flange-type parts." However, if this connection is only a part of a device, such as the connection between a flange and a pump, it is not appropriate to call the pump a "flange-type part." Smaller components, such as valves, can be called "flange parts." Gasket 607, designed specifically for the characteristics of large-diameter assembly machine chucks and considering the dimensions of various flanges (DN200, DN250), was designed and manufactured using auxiliary tooling after measurement and analysis. The tooling consists of two 470mm*70mm*19mm auxiliary tooling plates, with the width matching the equipment mounting plate and the thickness equal to the distance from the flange face to the chuck. Two symmetrical oblong holes were machined into the plates to meet the dimensional requirements of various flanges. The length of each oblong hole represents the difference between the maximum and minimum center dimensions of the DN200 and DN250 flanges. Gasket 607 is made of high-carbon steel. High-carbon steel (often called tool steel) contains carbon from 0.60% to 1.70% and can be quenched and tempered. Hammers, crowbars, etc., are made of steel with a carbon content of 0.75%; cutting tools such as drills, taps, and reamers are made of steel with a carbon content of 0.90% to 1.00%. High-carbon steel, after appropriate heat treatment or cold drawing hardening, has high strength and hardness, high elastic limit and fatigue limit, and acceptable cutting performance, but poor weldability and cold plastic deformation ability. Due to its high carbon content, it is prone to water quenching. Because cracks can occur, double-liquid quenching is often used, while oil quenching is frequently employed for small cross-section parts. This type of steel is generally used after quenching followed by medium-temperature tempering or normalizing, or in a surface-hardened state. It is mainly used to manufacture springs and wear-resistant parts. Carbon tool steel is a high-carbon steel with virtually no alloying elements added. It is also one of the lowest-cost tool steels, with good hot and cold workability and a wide range of applications. Its carbon content ranges from 0.65% to 1.35%, and it is specifically designed for tool making. The density of high-carbon steel is 7.81 g / cm³. 3 It can be used in the production of fishing gear.

[0034] One side of the equipment base 601 is connected to the gasket box 7, which can hold gaskets 607 of different sizes. This allows for easy replacement of gaskets 607 with different sizes of flanges 608 for compatibility. The equipment base plate 1 houses the driver 10 and battery 11, which are placed under the dustproof plate 9 secured by bolts B8. The driver 10 used in this device is an EPS-B1 driver with a response frequency of 1kHz, 3x overload capability, 2-stage notch filter, and input / output pulse frequency of 4Mbps. It offers high precision and resolution, shortening positioning time. Features include: suppression of external interference, fast command tracking, low cogging torque, regenerative processing, built-in dynamic brake, friction torque compensation, gain switching, zero clamping, password setting, automatic motor identification, power supply high-order harmonic countermeasures, LED bit display, built-in operation keyboard, and a voltage and power range of 220V 0.1KW-5.5KW and 380V 1KW-22KW. The all-digital AC servo system uses the latest chips to improve processing speed and enhances servo response control functions through newly developed speed loop and current loop control algorithms. It features a 2-stage notch filter, external interference suppression, friction torque compensation, gain switching, and supports input / output pulse frequencies up to 4Mbps, supports encoders up to 20-bit, and has rich internal position, internal speed, and internal torque control functions. With superior performance and reliable quality, it is a leader among domestically produced servo systems.

[0035] All electrical components mentioned in this article are connected to an external EPS-B1 main controller and 220V AC mains power, and the main controller can be a conventional known device such as a computer for control.

[0036] When using,

[0037] In summary, the auxiliary tooling of this large-diameter flange assembly machine uses the lateral movement group 2 to move the pusher tube group 6 laterally, the vertical movement group 3 to adjust the height of the pusher tube group 6, the infrared positioner 605 and the infrared sensor receiver 5 to automatically adjust their positions, and the motor C404 to drive the pusher tube thread column 403 to rotate. The connecting base plate 401 is connected to the pipe seat 402, and the butt pipe is placed on the pipe seat 402. The rotation of the pusher tube thread column 403 pushes the butt pipe on the pipe seat 402 forward. The motor C404 is limited by the fixed seat 405 and moves along the moving track of the fixed seat 405 with the connecting rod 406, so that the butt pipe is docked with the flange 608, thus completing the operation of the equipment.
