Description of the Invention: [Technical Field] The present invention relates to a riveting die, and more particularly to a riveting die for pressing a 'rivet nut' on a sheet metal part. [Prior Art] In industrial production processes, it is often necessary to firmly press some fasteners (such as rivet nuts) onto a sheet metal part by a punching machine or a rivet machine, that is, a staking process. The traditional method is to fix the riveting die on the punching machine. On the sheet metal part, a hole is required to be pressed into the rivet nut, and the sheet metal piece is placed on the punching hole of the pressing riveting die, and the hole of the sheet metal part is The inner holes of the punching die are opposite and have the same aperture. Then, the nut to be crimped is manually placed on the hole of the sheet metal member, and the nut is crimped onto the sheet metal member by a punching process. After the riveting is completed, the sheet metal part is also required to be removed to complete the demolding. ^The above traditional riveting process requires manual placement of the nut to be pressed into the hole of the sheet metal part. The operator is required to accurately fix the nut to be pressed and riveted, and the operator is skilled in the hole of the gold piece. Operation, low production efficiency, if the operator mistakes the position where the nut to be pressed and riveted is slightly deviated from the hole of the sheet metal part, the sheet metal part after the riveting is deformed or scrapped. SUMMARY OF THE INVENTION There is a present invention in which a kneading die for automatically introducing a rivet nut to be pressed is provided to improve production efficiency. The nut is riveted to a sheet metal piece, and the 'first elastic element and the first limit' are screwed to the bottom end of the first type of riveting die for pressing the riveting die including the body, and the guiding rod position Device. The 5H body includes a receiving hole rod; the guiding rod includes a top portion, and the guiding rod is received in the body screw 2, the first elastic element is disposed between the guiding rod and the first adjusting day a - when the elastic element is in a free state, the top of the guiding rod protrudes from the body for positioning the sheet metal part, and the limiting device is disposed on the guiding rod 嗲 too M ° 弟 弟 盯, 4 body To limit the axial displacement of the guide rod. [Embodiment] Gardmin refers to the bucking mold 2G of the present invention, and the (4) nut 50 is placed on the sheet metal member 40. The distal gold piece 4 () requires a hole 42 at the rivet nut, and the rivet nut 50 is a blind hole nut. Referring to Fig. 2 and Fig. 3', the press squeezing die 2 includes a body 22 having a receiving hole (2). In the present embodiment, φ·, ^ - η 裳 ^ 2 is a cylindrical shape having a first limit step ' The receiving hole 222 is a through hole, and the bottom of the body 22 is screwed to the first adjusting screw 25 .

The central hole 242 of the guide rod 24 is provided with a first elastic force 24G between the through guide rod 24 and the first adjusting screw 25, and the guiding rod 24 is elastically movable in the body 22. The first elastic member of the present body is a spring * 24 〇 ', the two ends of which are respectively abutted against the top, the adjusting screw 25 and the bottom surface of the guiding rod 24. The elastic properties of the first elastic member 24 can be adjusted by the first adjustment, i.e., the screw 25. The periphery of the positive rod 24 is cylindrical, and includes a first limiting flange opening U 246 ′ by the first limiting flange 244 and the first limiting step of the inner wall forming a first limiting device to define The guide 7 UJ9138 is removed from the top end of the body 22. The top 246 is used to position the meal. In the event that the guide bar 24 is unstressed, the resilient member 240 is in a state where the tapered top of the guide bar 24 extends out of the body 22. The outer diameter of the positive rod 24 is larger than the diameter of the aperture on the sheet metal member 4, and the front portion of the guide member 24 is placed on the top of the guide rod 24, and the tapered top portion 246 passes through and exceeds The hole 42 of the rice gold piece 40 is used to position the sheet metal piece. The bottom end of the #JHai guide rod 24 is screwed to the second adjusting screw 27. The take-up tray is now received: in the $-hole 242 of the guide rod 24, the second elastic member is provided between the pick-up needle 26 and the second adjusting screw 27, and the take-up can be used for guiding The rod 24 moves elastically. In the embodiment, the two ribs are topped on the bottom surface of the second adjusting screw to receive the elastic property of the second elastic member 260. The flange 26 includes The second limiting flange 2 6 2 ′ is formed by the second limiting step of the second limiting position of the inner wall of the rod 24 to form a second limiting device to limit the take-up needle 26 from the guiding, unstressed In the case of the second elastic element, the guide rod 24 is extended from the part of the ===, and the length of the retraction member is greater than the length of the rivet nut 5, and the rivet nut 50 can be sleeved. At the top of the take-up needle 26. Further, the member first places the rice gold piece 4 于 on the top of the hole Γ 246 of the wishing rivet die 20 and passes over the sheet metal member 40 and then the nut to be riveted 5〇 is set on the top of the take-up needle. 1339138. During the riveting process, the rivet nut 50 is transported downward under the pressure of the rivet machine: the movement is transmitted to the take-up needle 26, and the take-up needle is taken. 26 and the rivet nut 刈. jointly downward movement, and compress the second elastic element #26 〇. Since the top 246 of the guide rod .24 is tapered, when the rivet nut % moves to the fish When the tapered step top 246 is in contact, the rivet nut 5 is automatically centered on the guiding rod 24 by the tapered top portion (10), so that the rivet nut % is concentric with the hole 42 of the rice gold member 40, thereby Ensure the quality of the sheet metal part after pressing and riveting, and improve the production efficiency. The rivet nut 5〇 continues to move under the pressure of the rivet machine to transmit the pressure to the guide rod 24, and the guide rod 24 is pressed by the willow nut = movement The first elastic member 24 is compressed until the rivet nut (four) k 钣 ^ 40 and enters the receiving hole of the body 22, such that when the pressure of the rivet press is eliminated, the guiding rod 24 is at the first elastic member 24 At the same time, the take-up needle 2 "second elastic element _: automatically returns under the action" (four) rivet nut 5 〇 is then ejected in the receiving hole 222 to complete the automatic demoulding. Referring to FIG. 4, another embodiment of the present invention is different in that the guiding rod 24 is a solid structure, and the guiding member is gold 4: Γ2; 46, passing through and extending the sheet metal member. 40. Before staking, the shackle is first placed on the top 246 of the (10) positive rod 24, the top 246 is passed through the hole 42 of the gold piece 42, and the (four) rivet nut 50 is placed on the top at the top H of the continuation H. Conical, the rivet nut 50 can be centered by the π rod 24, so that the dust rivet nut 5 〇 and the hole 42 of the sheet metal member 40 are concentrically certified to improve the quality of the 钣 钣 gold piece 4 〇. , not to be fascinated, the invention meets the requirements of the invention patent, and the special 1339138 is proposed according to law.
