Description

Technical Field

[0002] Short Distance Upset Flange (SDUF) is a specific type of flange connection, commonly used in piping systems, pressure vessels and other industrial applications. The characteristic of this flange is that the material is compressed into the required shape and size in a short distance through a forging process to enhance its strength and durability.

[0003] In actual manufacturing, the blank is first heated to an appropriate temperature to reduce the yield strength of the material to facilitate subsequent roughing operations, and then a forging press or other special equipment is used to compress the blank within a short distance to expand it radially to form a flange. During this period, high-temperature toxic fumes will be generated above the blank, and oxide scale will also form on the surface of the blank. The toxic fumes will cause harm to the physical and mental health of the workers, and the oxide scale will fall off and fall into the forming cavity, requiring workers to hold an air gun to blow and clean it.

[0034] 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.

[0035] like Figures 1 to 9 As shown, a short-distance pier rough flange forming device includes a mounting table 10, a forming mechanism 20, a purification mechanism 30 and a cleaning mechanism 40, wherein:

[0036] The molding mechanism 20 is disposed above the mounting platform 10 and includes a lower mold 208 and an upper mold 213;

[0037] The purification mechanism 30 is arranged below the forming mechanism 20 and includes a piston cylinder 306, a piston block 308 and a filter 312. The piston block 308 is slidably connected to the inside of the piston cylinder 306, and the negative pressure behind the movement of the piston block 308 is used to absorb the harmful smoke during the roughening, and then the filter 312 is used to filter the harmful smoke;

[0038] The cleaning mechanism 40 is arranged in front of the molding mechanism 20 and includes an impeller shell 407, an impeller shaft 408, an impeller 409 and a cleaning strip 410. The impeller 409 is rotatably connected to the inside of the impeller shell 407 through the impeller shaft 408. The cleaning strip 410 is coaxially connected to the outer end of the impeller shaft 408. The impeller 409 and the cleaning strip 410 are driven to rotate by the filtered gas, and the rotating cleaning strip 410 is used to clean the molding cavity of the lower mold 208.

[0039] In this embodiment, the forming mechanism 20 also includes a hydraulic cylinder 201, which is provided with a pair of hydraulic cylinders 201 and symmetrically distributed on the left and right. The hydraulic cylinder 201 is installed on the mounting table 10 through a fixed plate 202, and is connected to a hinge seat 203 at the end of its piston rod. An L-shaped hinge bar 204 is hinged on the hinge seat 203, and a hinge seat 205 is installed at the lower part of the fixed plate 202, and an I-shaped hinge bar 206 is hinged on the hinge seat 205, and the hinge bar 206 and the hinge bar 204 are hinged to each other. The lower mold 208 is installed on the left and right hinge bars 204 through a mounting plate 207, and the upper mold 213 is coaxially installed on the lower end of the hydraulic press 214. The piston rod of the hydraulic cylinder 1 201 contracts and drives the lower mold 208 to move backward and upward around the front end of the hinge bar 206, so that the lower mold 208 is coaxially located directly below the upper mold 213, and then the hydraulic press 214 drives the upper mold 213 to move downward and squeeze the heated steel billet in the lower mold 208, thereby roughening the steel billet into a flange 50. After the roughening process is completed, the piston rod of the hydraulic cylinder 1 201 extends and drives the lower mold 208 to move forward and downward around the front end of the hinge bar 206, so as to automatically remove the roughened flange 50 and automatically clean the molding cavity of the lower mold 208.

[0040] In this embodiment, the purification mechanism 30 also includes a hydraulic cylinder 2 301, which is installed on the mounting platform 10 through a fixed plate 2 302, and a moving piece 303 is connected to the end of its piston rod, and a moving ring 304 is welded to the lower side of the moving piece 303, and the moving ring 304 is slidably connected to the outside of the piston cylinder 1 306, and the piston cylinder 1 306 is installed on the mounting platform 10 through a pair of mounting pieces 1 307, and the interior of the moving ring 304 is inlaid with a plurality of magnet strips. 305, and the magnet bar 305 and the piston block 308 are connected by magnetic force, the center of the piston block 308 is provided with a vent hole 308a, and a one-way valve 309 is threadedly connected at the vent hole 308a, and the front and rear ends of the piston cylinder 306 are respectively connected with an exhaust pipe 311 and an air intake pipe 310, the other end of the air intake pipe 310 is distributed around the lower mold 208 at intervals, and the other end of the exhaust pipe 311 is connected to the air inlet end of the filter 312. During the roughing process, the piston rod of the hydraulic cylinder 2 301 is extended and drives the moving ring 304 to move forward. Since the one-way valve 309 is in a blocked state, the gas in front of the piston block 308 can be transported to the filter 312 through the exhaust pipe 31, and the gas is filtered by the filter 312, and the negative pressure behind the piston block 308 is used to absorb the harmful smoke during roughing. Afterwards, the piston rod of the hydraulic cylinder 301 contracts and drives the movable ring 304 to move backward. Since the one-way valve 309 is in a conducting state, the gas behind the piston block 308 can pass through the vent hole 308a and be transferred to the front of the one-way valve 309.

[0041] In this embodiment, the cleaning mechanism 40 also includes a piston cylinder 401 and a piston block 403. The piston cylinder 401 is installed on the mounting platform 10 through a mounting plate 402. The piston block 403 is slidably connected to the interior of the piston cylinder 401, and a T-shaped air vent 403a is provided at the center of the piston block 403. A return spring 404 is connected between the front end of the piston block 403 and the front end of the piston cylinder 401. The front and rear ends of the piston cylinder 401 are respectively connected to an intake pipe 405 and an exhaust pipe 406. The other end of the intake pipe 405 is connected to the air outlet end of the filter 312, and the other end of the exhaust pipe 406 is connected to the side air inlet of the impeller shell 407. The rear end of the piston block 403 is coaxially connected to a connecting rod 411, and the rear end of the connecting rod 411 is coaxially fixed to the end face of the impeller shell 407. The filtered gas is transferred to the interior of the piston cylinder 401 through the suction pipe 405, and pushes the piston block 403 to move backward so that the cleaning strip 410 extends into the molding cavity of the lower mold 208. When the gas can pass through the vent hole 403a and be transferred to the interior of the impeller shell 407 through the exhaust pipe 406, the cleaning strip 410 can be pushed to rotate in the molding cavity of the lower mold 208.

[0042] In this embodiment, a spiral cooling pipe 209 is embedded inside the lower mold 208. When cold water flows inside the cooling pipe 209, the lower mold 208 can be cooled to prevent the lower mold 208 from being overheated and causing the hardness to decrease.

[0043] In this embodiment, a circular adsorption tube 210 is coaxially mounted on the upper side of the lower mold 208 through a plurality of fixing plates 211, a plurality of adsorption grooves 210a are evenly distributed on the inner side of the adsorption tube 210, a plurality of exhaust pipes 212 are evenly connected to the outer side of the adsorption tube 210, and the exhaust pipes 212 and the suction pipes 212 on the same side are interconnected. The adsorption grooves 210a on the adsorption tube 210 can absorb the toxic fumes during the roughing process, and transfer the toxic fumes to the piston cylinder 306 through the exhaust pipes 212 and the suction pipes 212.

[0044] In this embodiment, an inverted U-shaped support plate 215 is centrally mounted on the upper side of the mounting platform 10, and the support plate 215 is supported below the horizontal mounting plate 207. During the roughening process, the support plate 215 can effectively support the mounting plate 207 and the lower mold 213.

[0045] In this embodiment, the cleaning strip 410 is a C-shaped structure and has a row of cleaning holes 410a on both sides thereof, and two rows of cleaning hairs 410b are symmetrically distributed on both sides of the cleaning holes 410a. The impeller shaft 408 adopts a hollow pipe structure. The gas in the impeller shell 407 enters the cleaning strip 410 through the hollow impeller shaft 408, and is then ejected at high speed into the molding cavity of the lower mold 208 through the cleaning holes 410a. At the same time, the cleaning hairs on the cleaning strip 410 scrape the inner wall of the molding cavity, and the two work together to clean the oxide scale in the molding cavity.

[0046] The working principle of this short-distance pier flange forming equipment:

[0047] The piston rod of the hydraulic cylinder 1 201 contracts and drives the lower mold 208 to move backward and upward around the front end of the hinge bar 206, so that the lower mold 208 is coaxially located directly below the upper mold 213, and then the hydraulic press 214 drives the upper mold 213 to move downward and squeeze the heated steel billet in the lower mold 208, thereby roughening the steel billet into a flange 50. After the roughening process is completed, the piston rod of the hydraulic cylinder 1 201 extends and drives the lower mold 208 to move forward and downward around the front end of the hinge bar 206, so as to automatically remove the roughened flange 50 and automatically clean the molding cavity of the lower mold 208.

[0048] During the roughing process, the piston rod of the hydraulic cylinder 2 301 is extended and drives the moving ring 304 to move forward. Since the one-way valve 309 is in a blocked state, the gas in front of the piston block 1 308 can be transported to the filter 312 through the exhaust pipe 1 31, and the gas is filtered by the filter 312. At the same time, the negative pressure behind the piston block 1 308 is used to absorb the harmful smoke during roughing. Afterwards, the piston rod of the hydraulic cylinder 2 301 is contracted and drives the moving ring 304 to move backward. Since the one-way valve 309 is in a conducting state, the gas behind the piston block 1 308 can pass through the vent hole 1 308a and be transferred to the front of the one-way valve 309.

[0049] The filtered gas is transferred to the interior of the piston cylinder 401 through the suction pipe 405, and pushes the piston block 403 to move backward so that the cleaning strip 410 extends into the molding cavity of the lower mold 208. When the gas can pass through the vent hole 403a and be transferred to the interior of the impeller shell 407 through the exhaust pipe 406, the cleaning strip 410 can be pushed to rotate in the molding cavity of the lower mold 208.

[0050] Therefore, the embodiments disclosed above are only illustrative in all aspects and are not exclusive. All changes within the scope of the present invention or within the scope equivalent to the present invention are included in the present invention.
