Description
Technical Field
[0001] The present invention relates to the technical field of automated forging equipment, and in particular to automated forging equipment and a forging method for flange production based on robot conveying. Background Art
[0002] A flange is a disc-shaped component used to connect pipes. It has holes for bolts to secure it. To ensure efficient fluid delivery, a protrusion is often added to the flange's connection surface to accommodate a seal.
[0003] During forging, the material must be heated first. Once heated, it is placed directly into the forming cavity and hot-formed by applying pressure. Due to the high heating temperature of the forging, the material is usually transferred manually after heating. However, manual loading is difficult, poses a threat to the operator's safety, and cannot guarantee continuous forging quality.
[0004] Furthermore, flange protrusions are typically arranged vertically or at an angle, making it difficult to form a right-angled sealing layer. However, since the workpiece is heated uniformly during hot pressing, the workpiece experiences uniform deformation during the press forming process, making it easier for the workpiece to fill the right angles of the forming cavity, affecting the forming quality. Summary of the Invention
[0005] The object of the present invention is to provide an automated forging device and a forging method for flange production based on robot conveying, so as to solve the problems raised in the prior art.
[0006] To achieve the above object, the present invention provides the following technical solutions:

[0008] Automated forging equipment is used to forge workpieces. The machine tool serves as the main installation basis and is used to fix various devices. The workpiece is heated by a heating furnace. After heating, the workpiece falls into the conveyor line. When the workpiece is conveyed to the end of the stroke, the workpiece is moved to the working chamber by the transfer device. The temperature control device is placed in the switching slot and can be moved into the working chamber. The workpiece is locally heated by the temperature control device to improve local plasticity and facilitate the improvement of forming quality.
[0009] Furthermore, the power device includes an upper die, a bottom die and a press, the press is connected to the machine tool, the output end of the press is transmission-connected to the upper die, and the bottom die is placed in the working chamber;
[0010] The temperature regulating device includes a heating component, which is used to heat the sealing layer of the workpiece;
[0011] When heating: the heating component is placed in the working chamber.
[0012] The surface of the flange used for connection is provided with a protrusion for installing a seal to improve the sealing efficiency. The protrusion is a sealing layer. When the workpiece is moved into the working chamber by the transfer device, the heating component is extended into the working chamber to locally heat the sealing layer of the workpiece by the heating component, so that the plasticity of the sealing layer of the workpiece is improved. During forging, the power output by the press drives the upper die to press down. Under the action of pressure, due to the local temperature difference of the workpiece, the temperature-high place is subjected to greater pressure deformation, and the sealing layer of the workpiece is filled into the cavity of the bottom die, thereby improving the forging quality.
[0013] Furthermore, the transfer device includes a transfer robot, a gripper and a clamp, and the movable end of the transfer robot is connected to the gripper and the clamp respectively. The gripper is used to clamp the unformed workpiece, and the clamp is used to clamp the formed workpiece.
[0014] The transfer robot uses a multi-degree-of-freedom robotic arm with a gripper and clamp installed at the end. The gripper is made of high-temperature resistant material and is used to deliver the workpiece from the conveyor line into the working chamber. After the forming is completed, the formed workpiece is removed from the working chamber by the clamp, which facilitates automated forging.
[0015] Furthermore, the heating assembly includes a carrier plate, a positioning cylinder, a heating coil and a conductive sheet. The positioning cylinder and the switching slot are fastened together, the output end of the positioning cylinder and the carrier plate are transmission-connected, a heating chamber is provided on the carrier plate, the heating coil is placed in the heating chamber, two conductive sheets are provided in the heating chamber, the two conductive sheets are respectively in contact with the heating coil, the two conductive sheets are respectively electrically connected to the two wiring terminals of the heating power supply, and the heating coil is arranged along the outer circle of the sealing layer of the workpiece.
[0016] The positioning cylinder is placed in the switching slot and is used to output linear displacement to drive the carrier plate to move. After the workpiece is moved into the working chamber by the gripper, the carrier plate is pushed into the working chamber by the positioning cylinder. A heating coil is provided in the heating chamber, which is electrically connected to the heating coil through two conductive sheets, so that the heating coil parts in the two conductive sheets enter the heating circuit and heat the outer circle of the sealing layer of the workpiece, thereby improving the local plasticity of the outer circle of the sealing layer, so that after being pressurized, it can completely fill the cavity of the bottom mold and ensure the molding quality.
[0017] Furthermore, the heating assembly also includes several expansion cylinders, and several expansion grooves are provided on the lower side of the heating chamber. The expansion cylinders are placed in the expansion grooves. The output ends of the expansion cylinders are transmission-connected to the heating coils. A conductive sheet is located at the end of the heating coil, and the other conductive sheet is slidingly connected to the middle section of the heating coil.
[0018] During the forging process for flanges of varying specifications, the expansion cylinder within the expansion slot controls the length of the heating coil connected to the heating circuit, thereby controlling the heating range and adapting to the manufacture of flanges of various specifications. During this process, one end of the heating coil is fixed by a conductive sheet, while the other end is a movable end that slides into contact with the conductive sheet at the end, facilitating circuit connection and automatically controlling the localized heating range, improving applicability.
[0019] Furthermore, the temperature control device also includes a positioning component, a photosensitive groove is provided on the carrier plate, the positioning component is placed in the photosensitive groove, the positioning component includes a parallel light source, a photosensitive layer and an electrode sheet, the parallel light source and the photosensitive layer are respectively fastened to the photosensitive groove, the parallel light source and the photosensitive layer are centrally arranged and tilted, the photosensitive layer is located on the reflected light path of the parallel light source, two electrode sheets are provided on the photosensitive layer, the two electrode sheets are respectively electrically connected to the two wiring terminals of the detection power supply to form a detection circuit, and the expansion cylinder is electrically connected to the detection circuit.
[0020] The positioning component is placed in the photosensitive tank, and the photosensitive layer and the parallel light source are both arranged at an angle. After the bottom mold is placed in the working cavity, the parallel light source emits light so that the emitted light is irradiated into the bottom mold cavity and reflected. Due to the existence of the workpiece sealing layer, the bottom mold cavity is arranged in a stepped shape. The reflected light path of the parallel light source irradiating the bottom part of the cavity will fall on the photosensitive layer and stimulate electron-hole pairs to participate in conduction, so that the detection circuit is turned on; when the parallel light is irradiated on the higher part of the cavity, under the condition that the incident angle remains unchanged, the reflection point is offset, so that the final reflected light path deviates from the original reflected light path, that is, the light intensity irradiated on the photosensitive layer is weakened, and the current of the detection circuit is reduced. The extension length of the expansion cylinder is controlled according to the circuit current, thereby automatically adjusting the heating range. The smaller the circuit current, the smaller the circle formed by the expansion cylinder to control the heating coil.
[0021] As an optimization, the photosensitive layer is arranged along the radial direction of the heating coil. This arrangement follows the radius of the circular heating area formed by the heating coil, resulting in different reflected light paths at different stepped sections. This facilitates detection of the size of the workpiece's sealing layer area to be forged, improving automated forging efficiency.

[0023] During heating: the ejector cylinder and the carrier plate are connected by transmission, and the output end of the positioning cylinder and the card slot are not in contact.
[0024] The ejector cylinder is fixed on the machine tool, and the output end extends into the working chamber. When heating, it is used to drive the carrier plate to move up, and the output end of the positioning cylinder is disengaged from the card slot. As the carrier plate moves up, the distance between the heating coil and the workpiece is reduced, which facilitates automatic heating. After the heating is completed, the ejector cylinder moves the carrier plate downward and inserts the positioning cylinder into the card slot, so that the positioning cylinder drives the carrier plate back to the switching slot, so that the workpiece falls to the bottom of the working chamber. The workpiece is forged by the cooperation of the upper die and the bottom die. After forging is completed, the workpiece is ejected from the working chamber by the ejector cylinder, thereby performing automated forging.
[0025] Compared with the prior art, the beneficial effects of the present invention are as follows: the sealing layer of the workpiece is locally heated by the heating component, so that the plasticity of the sealing layer of the workpiece is improved. During forging, the power output by the press drives the upper die to press down. Under the action of pressure, due to the local temperature difference of the workpiece, the places with high temperature are compressed and deformed more greatly, and the sealing layer of the workpiece is filled into the cavity of the bottom die, thereby improving the forging quality; the two conductive sheets are respectively electrically connected to the heating coils, so that the heating coil parts in the two conductive sheets enter the heating circuit and heat the outer circle of the sealing layer of the workpiece, thereby improving the local plasticity of the outer circle of the sealing layer, so that after being pressurized, it is convenient to completely fill the cavity of the bottom die. , ensuring the molding quality; due to the existence of the workpiece sealing layer, the bottom model cavity is arranged in a stepped shape, and the reflected light path of the parallel light source irradiating the bottom part of the cavity will fall on the photosensitive layer, and stimulate electron-hole pairs to participate in conduction, so that the detection circuit is turned on; when the parallel light is irradiated on the higher part of the cavity, under the condition of unchanged incident angle, the reflection point is offset, so that the final reflected light path deviates from the original reflected light path, that is, the light intensity irradiated on the photosensitive layer is weakened, and the current of the detection circuit is reduced. The elongation length of the expansion cylinder is controlled according to the circuit current, thereby automatically adjusting the heating range. The smaller the circuit current, the smaller the circle formed by the heating coil controlled by the expansion cylinder. BRIEF DESCRIPTION OF THE DRAWINGS

After the workpiece is moved into the working chamber 11 by the gripper 42, the carrier plate 311 is pushed into the working chamber 11 by the positioning cylinder 312. A heating coil 314 is provided in the heating chamber 3111, and two conductive sheets 315 are respectively in contact with and electrically connected to the heating coil 314, so that the heating coil 314 part in the two conductive sheets 315 enters the heating circuit and heats the outer circle of the sealing layer of the workpiece, thereby improving the local plasticity of the outer circle of the sealing layer, so that after being pressurized, it can completely fill the cavity of the bottom mold 22 to ensure the molding quality.

When heating, it is used to drive the carrier plate 311 to move upward, and the output end of the positioning cylinder 312 is disengaged from the card slot 3112. As the carrier plate 311 moves upward, the distance between the heating coil and the workpiece is reduced, which facilitates automatic heating. After the heating is completed, the ejector cylinder 24 mobilizes the carrier plate 311 to move downward and inserts the positioning cylinder 312 into the card slot 3112, so that the positioning cylinder 312 drives the carrier plate 311 back to the switching slot 12, so that the workpiece falls to the bottom of the working chamber 11, and is forged by the cooperation of the upper die 21 and the bottom die 22.
