Description of the Invention: [Technical Field] The present invention relates to a forging machine, and more particularly to a forging machine having a synchronous returning function. [Prior Art] The general forging part forming machine generally includes a machine table, a plurality of mold mechanisms disposed on the machine table, and a plurality of punching and forging mechanisms respectively disposed on the machine table and used for punching the blanks in the mold mechanism, and a majority A return mechanism that is placed on the machine and used to drive the parts of the mold mechanism out. When the forging part molding machine is actuated, the blanking materials are respectively forged into a predetermined shape by the punching and forging mechanism, and then the material returning mechanism drives the semi-finished products in the mold mechanism out of the mold mechanism, respectively. So that the semi-finished products are displaced to other mold mechanisms for punching and forging. However, in general, the material returning mechanism is composed of gas and oil red, which can be driven by the knife (4). After the punching rod of the punching and forging mechanism is separated from the mold mechanism, the semi-finished product is pushed out of the mold mechanism by the feeding rod. f. The material return mechanism consisting of oil red will not only increase the cost of the forging part molding machine, but also the energy consumption of the pressure cylinder will be improved.

As shown in Figures 3 to 5, the forging machine with synchronous unloading function of the present invention will be used in conjunction with the loading and unloading of the machine assembly 3, and the aging and discharging device 1 has Horizontally fixed in the machine table 3 and straddle the feeding guide u of the top surface of the mounting f 61, respectively disposed at the opposite ends of the feeding guide u - the feeding cylinder 12 and the discharging guide 13 , and - are arranged The feed guide u is a feeder 14 at the end of the feed cylinder 12, and the feed cylinder 12 is stacked with a plurality of block blanks (10) to be punched, and the feed guide u is available for feeding The blanks 100 of the same material 12 are sequentially transferred into the mold 62, and the feed state 14 can be driven to protrude the feed rod 141' toward the feed rail U every predetermined time. The blank 1GG in the material guide rail 11 is pushed into the mold and pushed forward by the thrust of the displacement of the blank of 100, and the parts of the 8 1314483:: mold 62 are moved to the discharge guide & The shape of the molded part is second, and the user can change the shape of the punch rod 52 according to the desired punching and pressing. In the upper Han Dynasty, the corresponding mold 62 is used to drive the binary action. The impact of the movement (4) will be rotated, and at the same time, the eccentricity will be driven, and the bottom end of the impact seat 51 will be the fulcrum mechanism. The upper and lower displacements are further linked to the swaging and forging between the punching position and the returning position. When the swaging mechanism 5 is in the punching position, the punch 52 is lowered into the mold 62 and the embryo in the mold 62 has been driven by the transmission mechanism 4 from the punching position. At the material position, the impact link 45 is eccentrically and rotated, and gradually shifts forward and upward, and gradually pulls up the impact seat. And the punching rod 52 in the π-moving mold 62 is gradually detached from the mold 62. At the same time, by pushing the rod 71 of the machine table 3, the pushing mechanism 7 fixed to the impact seat 51 is also synchronized upward. Pulling and moving to the upper position of the punching rod ^ After releasing the mold * 62, the pushing rod 73 will start to abut against the bottom end surface of the return rod 63, and push the return rod 63 upward to force the return rod The Μ is inserted into the mold 62 and the part that is punched and forged is ejected from the mold (4). / As shown in Figures 5, 6, and 8, when the punching and forging mechanism 5 is displaced to the returning position j and is again displaced toward the punching position, the feeder 14 simultaneously feeds the next blank. Pushing toward the mold 62, and removing the part ι〇ι mold 62 from the outside of the mold 62, the blank is removed from the machine table 3, and the blank 1〇〇 is pushed into the mold 9.1314483 62' and is returned to the return material The top of the rod 63. After the point, the connecting rod 45 is moved by the eccentric rotating shaft 42 to move up and pivoted over the highest 51 synchronous main rod 45, and the impacting seat 51 is pushed down, and the top of the impacting seat is pushed down 7 to push the pushing mechanism 7' The bottom end of the return rod 63 moves downward from the S i to be separated from the return rod 63. After the distance of the return rod 63, the position of the return rod 63 is restricted by _64, so that it is moved in and positioned by the top surface (four) U). In the bottom of the mold 62, the punching rod 52 in the man mold 62 starts to punch the forging embryo _ the billet 100 is forged into the part 101 of the predetermined shape. Then, the rotating shaft 42 will again drive the impact link 45 to repeat the above. The upward swinging motion of the squatting movement is repeated between the punching position and the returning position. In this embodiment, the top end of the pushing rod 73 and the returning rod are at the bottom end. It is necessary to make the punching rod 52 be displaced by the impacting seat 51 and disengaged from the material, and at the same time, the pushing rod 51 is synchronously moved up and the top pushing rod is pushed up and pushed back, so that the part (9) can be smoothly passed. The top mold is externally pressed and pushed away from the mold 62 by the lower-boiler (10). Therefore, the user can push out the parts outside the mold 62 as desired. 1 〇 1 height, relative to the joint Μ Turn the ejector rod 73 to change the distance between the ejector rod 73 and the return rod 3. In summary, through the punching mechanism 5 at the punching position and the returning position: When the displacement changes, the pull rod 71' extending through the mold mechanism 6 and the warp machine table 3 can synchronously interlock the structure of the pushing mechanism 7 to be displaced, so that the pushing mechanism 7 can be displaced to the retreating mechanism 5 In the process, the stripping rod 63 of the mold mechanism 6 is driven to move, and after the punching and forging 10 1314483 mechanism 5 is separated from the mold 62, the parts 101 which are to be swaged and finished are simultaneously pushed out of the mold 62, thereby simplifying the forging machine. The material returning structure design makes the detachment of the parts in the mold 62 more simple and convenient. In addition, the impacting seat 51 can synchronously interlock the pushing mechanism 7 to move up and down, and the punching rod 52 is swaged and withdrawn. Simultaneously, the mold 62 is forced to press the forging rod 63 out of the sheet out of the mold 62, and the stripping rod 63 can move the embryo to be swept to the mold 62t, so that the billet is just entering The detachment of the material forging and forging can be coherent for I Λ, and it is more convenient. The purpose of the present invention is indeed to the present invention. The above description is only for the preferred embodiment of the present invention, and ♦ = this defines the scope of the practice of the present invention, that is, according to the present invention, Shen Xin = Wai And the simple equivalent changes and modifications made by the description of the invention are still within the scope of the present invention.
