Description

Technical Field

[0001] The 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 part that is mainly used to connect pipes. It is provided with holes and fixed by bolts. In order to ensure the efficiency of fluid transportation, a protrusion is usually provided on the connection surface of the flange to cooperate with the seal for sealing.

[0003] When forging, it is necessary to heat first, and after heating, it is directly placed in the forming cavity and hot-formed by applying pressure. Due to the high heating temperature of the forging, after heating, the material is usually transferred manually, which is difficult and threatens the safety of the operator, and cannot guarantee the continuous forging quality.

[0004] In addition, the flange protrusion is generally arranged vertically or obliquely, and the right-angle sealing layer is not easy to form. However, since the workpiece is heated evenly during the heating process, the workpiece is subjected to the same force and deformation speed during hot pressing, which makes it easy for the workpiece to fill the right angle of the molding cavity, affecting the molding quality. Summary of the invention

[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 to 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;

[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 a transfer device, the heating component extends into the working chamber, and 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 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 adopts a multi-degree-of-freedom robotic arm with a gripper and a 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 taken out of the working chamber by the clamp to facilitate 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 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 pressed, it can completely fill the cavity of the bottom mold and ensure the molding quality.

[0017] Furthermore, the heating assembly also includes a plurality of expansion cylinders, a plurality of 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 coils, and another conductive sheet is slidingly connected to the middle section of the heating coils.

[0018] During the forging process of flanges of different specifications, the length of the heating coil connected to the heating circuit is controlled through the expansion cylinder in the expansion groove, thereby controlling the size of the heating range and adapting to the manufacturing of flanges of multiple specifications. During the process of controlling the access length, one end of the heating coil is fixed by the conductive sheet, and the other end is the active end, and it slides in contact with the conductive sheet at the end, so as to facilitate the access to the circuit, automatically control the local heating range, and improve 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 and tiltedly arranged, 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 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 groove, and the photosensitive layer and the parallel light source are 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 irradiates the bottom mold cavity and reflects. 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 irradiates 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 irradiating 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 controlling the heating coil.

[0024] The ejector cylinder is fixed on the machine tool, and the output end extends into the working chamber. When heating is performed, it is used to drive the carrier plate to move up. 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 is convenient for 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, and the workpiece is forged through the cooperation of the upper die and the bottom die. After forging is completed, the workpiece is ejected out of the working chamber by the ejector cylinder, so as to perform automatic 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 downward. Under the action of pressure, due to the local temperature difference of the workpiece, the high temperature area is 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 contacted and electrically connected with 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 compressed, it is convenient to completely fill the cavity of the bottom die. , to ensure 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 irradiated on 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 irradiates 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.
