Description
Technical Field
[0001] This invention relates to the field of flange forging technology, specifically to a flange forging hydraulic press that facilitates control of workpiece temperature. Background Technology
[0002] A flange, also known as a flange plate, is a component used to connect pipes, valves, and equipment. It typically consists of a circular metal ring with holes and bolt holes, allowing various components to be connected by bolts. Flanges are commonly used in industrial applications, such as piping systems, to connect different components to ensure sealing and safety. They can be designed and manufactured according to different needs and standards. Die forging is a key step in flange production, involving placing a heated blank into a die fixed on forging equipment to form the flange. However, existing flange forging hydraulic presses suffer from temperature drops due to prolonged contact with outside air during the forging process. This temperature drop not only increases the forging difficulty but also requires the operator to hold the forging and reheat it in a furnace to reach the required forging temperature. Furthermore, existing flange forging hydraulic presses often produce oxide scale during forging, which, due to its heat, can burn the operator. Summary of the Invention
[0003] The purpose of this invention is to address the shortcomings of existing technologies by providing a flange forging hydraulic press that facilitates temperature control of the workpiece. This addresses the issues raised in the background section regarding existing flange forging hydraulic presses, where the forging workpiece's temperature decreases due to prolonged contact with external air during the forging process. This decrease not only increases the forging difficulty but also requires the operator to hold the forging and place it back into the furnace for reheating to meet the forging temperature. Furthermore, existing flange forging hydraulic presses generate oxide scale that scatters during forging, and since the oxide scale also has a certain temperature, it can burn the operator.

[0010] Preferably, the temperature-controlled forging structure includes a through-hole plate fixed to the boss, and a matching frame with a blanking hole is welded and fixedly installed on the through-hole plate. At the same time, a synchronous cylinder is fixedly installed on the rear side of the matching frame. An isolation cover with a notch is fixedly installed above the matching frame, and an electromagnetic induction coil is fixedly installed inside the isolation cover by a fixing rod. The electromagnetic induction coil is electrically connected to the electromagnetic heating controller.
[0011] By adopting the above technical solution, heating can be controlled through the installation of electromagnetic induction coils.
[0012] Preferably, a cavity ring is fixedly installed above the isolation cover, and an air jet pipe is embedded and installed inside the cavity ring. At the same time, connecting frames with a hollow internal structure are fixedly installed on both sides of the outer wall of the cavity ring. A connecting pipe runs through the connecting frame and is embedded and connected to the outer wall of the cavity ring. The connecting frame is fixedly installed above the boss.
[0013] By adopting the above technical solution, the gas is arranged in a ring around the cavity.
[0014] Preferably, the matching frame has a connecting frame with the same material dropping hole sliding inside, and a mold base is fixedly installed on the top of the connecting frame. At the same time, the rear side of the connecting frame is fixed to the bottom of the electromagnet through the output end of the synchronous cylinder, and the electromagnet is fixedly connected to the output end of the synchronous cylinder.
[0015] By adopting the above technical solution, electromagnetic adsorption and fixation are achieved through the use of electromagnets.
[0016] Preferably, the airbag is provided in one set, and the airbag is provided with a heat-insulating coating on its surface.

[0020] Preferably, the jet pipes are inclined inside the cavity ring, and the jet pipes are arranged in a ring array.
[0021] By adopting the above technical solution, the jet pipe is installed to achieve embedded and continuous connection.
[0022] Compared with the prior art, the beneficial effects of the present invention are: this flange forging hydraulic press facilitates control of workpiece temperature. (1) This case solves the problem of existing flange forging hydraulic presses reducing their temperature when the forging workpiece is in contact with the outside air for a long time during the flange forging process. When the temperature of the forging workpiece decreases, it not only increases the difficulty of forging, but also requires the operator to clamp the forging workpiece and place it in the combustion furnace again to heat it to the appropriate forging temperature. When the forging temperature of the forging workpiece is not high enough, the operator uses the electromagnetic heating controller to control the operation of the electromagnetic induction coil. When the electromagnetic induction coil is running, it heats the placed forging workpiece. During the heating process of the forging workpiece, the temperature sensing module always monitors the heating temperature in real time, which makes it convenient for the operator to control different heating temperatures of the forging workpiece. When the forging workpiece is heated to the appropriate forging temperature, the operator controls the electromagnetic induction coil to stop running, thus forging the forging workpiece that has been heated by both. (2) By using the following components in the forging blowing structure and temperature-controlled forging structure: air bag, connecting pipe, guide rod, boss, material drop hole, collection box, air jet pipe and cavity ring, the problem of oxide scale being scattered during the forging process of the existing flange forging hydraulic press is solved. At the same time, since the oxide scale also has a certain temperature, it may burn the operator. When the guide rod moves downward, it squeezes the air bag. When the air bag is squeezed, the gas inside the air bag is transported to the cavity ring through the connecting pipe. The gas entering the cavity ring is ejected through the air jet pipe. The ejected gas blows the oxide scale off the surface of the forging. At the same time, the blown oxide scale falls into the collection box for collection. (3) By setting an isolation cover in the temperature-controlled forging structure, the heat generated during the operation of the electromagnetic induction coil during the continuous heating of the forging is diffused, which prevents the operator from approaching the boss. When the electromagnetic induction coil is working, the heat is concentrated inside the isolation cover. When the heat is concentrated, it not only shortens the heating time of the forging but also avoids the situation where the heat diffuses and prevents the operator from approaching. (4) By using the connecting frame, die base, electromagnet, synchronous cylinder and matching frame set in the temperature-controlled forging structure, the problem of existing die bases being fixed by bolts is solved. As a result, when the die base needs to be replaced, it is not only troublesome to replace, but also requires frequent disassembly of bolts. When the die base needs to be replaced, the synchronous cylinder is controlled to push the connecting frame out of the matching frame by the electromagnet. After the electromagnet stops working, the connecting frame and the die base are disassembled and separated together, so that the connecting frame of the same model and the die base of a different model can be replaced.

[0025] 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.
[0026] Please see Figure 1-9 This invention provides a technical solution: a flange forging hydraulic press that facilitates workpiece temperature control, such as... Figure 1 , Figure 2 and Figure 3 As shown, the structure includes a forging and blowing structure 1. The forging and blowing structure 1 includes a base platform 101 on both sides, with a controller 102 and an electromagnetic heating controller 103 fixedly installed on each side. A base body 104 is fixedly installed on the base platform 101, and a boss 105 is welded and fixedly installed on the base body 104. A connecting groove 106 is provided in front of the boss 105, and a collection box 107 slides inside the connecting groove 106. A material discharge hole 108 is provided above the boss 105 and extends into the connecting groove 106. The above components constitute a pull-out sliding structure, which facilitates the pull-out separation of the collection box 107 to dump the collected oxide scale.
[0027] Furthermore, in the above scheme, an airbag 109 is fixedly installed above the base platform 101. One set of airbags 109 is provided, and the airbags 109 are coated with a heat-insulating coating. The arrangement of one set of two airbags not only demonstrates the practicality of the installation but also the synchronous force-bearing and compression capabilities of the components. Furthermore, the simultaneous compression and gas discharge of the components is also demonstrated by the arrangement of one set of two airbags. Simultaneously, the heat-insulating coating on the surface of the airbags 109 prevents damage to the airbags under high temperatures. When airbag 109 melts due to heat, it cannot be used normally. One side of airbag 109 is embedded and connected to one end of connecting tube 1010. At the same time, the other end of connecting tube 1010 passes through base body 104 and boss 105 and extends above boss 105. Meanwhile, guide rod 1011 and mounting bracket 1012 are fixedly installed on the top and rear sides of base platform 101, respectively. Connecting platform 1013 is fixedly installed on guide rod 1011 and mounting bracket 1012, and through hole plate 1014 is slidably installed on guide rod 1011.
[0028] Furthermore, in the above scheme, a pressing rod 1015 is fixedly installed at the bottom of the through-hole plate 1014, and a stamping forging head 1017 is fixedly installed at the bottom of the through-hole plate 1014 via a connecting seat 1016. At the same time, a fixed plate 1018 with a temperature sensing module 1019 is fixedly installed on the surface of the stamping forging head 1017. The upper part of the through-hole plate 1014 is fixedly connected to the output end of the hydraulic cylinder 1020, and the hydraulic cylinder 1020 is fixedly installed above the connecting platform 1013. The above components constitute a lifting and adjusting structure. When using the lifting and adjusting structure constituted by the above components, not only is the synchronous drive adjustment of the above components reflected, but also the stamping and forging performance of the above components on the forgings is reflected.
[0029] like Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 and Figure 9As shown, a temperature-controlled forging structure 2 is fixedly installed above the forging and blowing structure 1. The temperature-controlled forging structure 2 includes a through-hole plate 201 fixed on the boss 105, and a matching frame 202 with a blanking hole 108 is welded and fixedly installed on the through-hole plate 201. At the same time, a synchronous cylinder 203 is fixedly installed on the rear side of the matching frame 202. An isolation cover 204 with a notch is fixedly installed above the matching frame 202. The isolation cover 204 has an overall "corrugated pipe" structure and is made of flame-retardant and heat-insulating material. When the above-mentioned components have an overall "corrugated pipe" structure, This not only demonstrates the encapsulation of the aforementioned components but also their internal fixed installation. Furthermore, the "corrugated pipe" structure of the overall shape of the components effectively showcases the practicality and protective enclosure of the installation. Additionally, the use of flame-retardant and heat-insulating materials in the isolation cover 204 prevents heat diffusion, ensuring that the operator cannot approach and control the device if the temperature becomes too high. Moreover, an electromagnetic induction coil 205 is fixedly installed inside the isolation cover 204 via a fixing rod, and the electromagnetic induction coil 205 is electrically connected to the electromagnetic heating controller 103.
[0030] Furthermore, a cavity ring 206 is fixedly installed above the isolation cover 204, and a jet pipe 207 is embedded and installed inside the cavity ring 206. The jet pipe 207 is inclined inside the cavity ring 206 and arranged in a ring array. When the above-mentioned components are inclined inside the cavity ring 206, the blown air is blown out at a certain angle. When the blown air has a certain angle, it forms a rotation mode, effectively blowing the carnival oxide scale off the surface of the boss 105 for material collection. At the same time, the arrangement of the jet pipe 207 in a ring array demonstrates the practicality of the equidistant distribution of the above-mentioned components and also demonstrates the synchronous air blowing performance of the above-mentioned components. Meanwhile, connecting frames 208 with hollow internal structures are fixedly installed on both sides of the outer wall of the cavity ring 206. Connecting pipes 1010 pass through the connecting frames 208 and are embedded and connected to the outer wall of the cavity ring 206. The connecting frames 208 are fixedly installed above the boss 105.
[0031] Furthermore, the above scheme includes a connecting frame 209 with a material drop hole 108 sliding inside the matching frame 202, and a mold base 2010 is fixedly installed on the top of the connecting frame 209. At the same time, the rear side of the connecting frame 209 is fixed to the bottom of the electromagnet 2011 through the output end of the synchronous cylinder 203. The electromagnet 2011 is fixedly connected to the output end of the synchronous cylinder 203. The above components constitute a driving sliding structure. The driving sliding structure constituted by the above components can effectively push out and pull back the mold base 2010. Moreover, when the connecting frame 209 of the same specification can be equipped with mold bases 2010 of different diameters, it is convenient to replace the mold bases 2010 of different diameters.
[0032] In the above scheme, when the forging needs to be forged, the operator controls the synchronous cylinder 203 to operate, driving the connecting frame 209 and the mold base 2010 to extend outside the matching frame 202. The operator then places the forging inside the mold base 2010. The operator then controls the synchronous cylinder 203 again to operate, retracting the mold base 2010 inside the matching frame 202. Next, the operator controls the hydraulic cylinder 1020 to operate, driving the through-hole plate 1014, extrusion rod 1015, connecting seat 1016, stamping forging head 1017, fixed plate 1018, and temperature sensing module 1019 to move downwards synchronously. This allows the stamping forging head 1017 to stamp and forge the forging. When the extrusion rod 1015 compresses the airbag 109, the gas inside is transported through the connecting pipe 1010 to the cavity ring 206 and the jet pipe 207, where it is ejected. When the gas blows onto the surfaces of the connecting frame 209 and the mold base 2010, it blows the residual oxide scale into the collection box 107 for collection. When the temperature sensing module 1019 detects that the forging temperature is not high, the controller 102 will display an alarm. Then, the operator uses the electromagnetic heating controller 103 to control the electromagnetic induction coil 205 to heat the forging. When the forging temperature reaches the forging temperature, the operator controls the hydraulic cylinder 1020 to repeat the forging process. After the forging is formed, the operator controls the hydraulic cylinder 1020 to stop working and then controls the synchronous cylinder 203 to work again, driving the connecting frame 209 and the mold base 2010 to extend outside the matching frame 202. The operator can then remove the forging. The oxide scale that has fallen into the collection box 107 can be pulled out of the collection box 107 and the collected oxide scale can be poured out.
