Description

Technical Field

[0001] This invention relates to the field of automotive parts stamping technology, specifically to an automotive parts stamping die. Background Technology

[0002] In automotive parts manufacturing, non-metallic materials such as nylon and engineering plastics are often used in stamping processes to produce functional parts such as pulleys, brackets, and pads. To ensure dimensional accuracy and surface quality, special stamping dies are required to position and shape the workpieces. The dies typically include upper and lower dies, guide structures, and auxiliary mechanisms.

[0003] A search revealed a Chinese patent publication number CN222856483U, which discloses a stamping die for automotive parts. The die includes a base, a collecting component on one side of the lower die, and a support bracket and an electric slide rail. A spring is fixedly connected to the bottom of the support block, and a limit baffle is fixedly connected to the top of the base. The electric slide rail controls the left and right sliding of the inclined rail. A material frame is fixedly installed on the top of the base. An electromagnet is fixedly installed on the top of the upper die, and an electromagnet is fixedly installed on the bottom of the inclined rail. Through the collecting component, the upper die stamps the sheet metal. The top surface of the support block is flush with the bottom of the lower die's inner cavity. The spring lifts the sheet metal, and the electromagnet causes the upper die to attract the sheet metal. When the power to the electromagnet is turned off, the power to the electromagnet is turned on, attracting the sheet metal to the top of the inclined rail. Then, the power to the electromagnet is turned off, causing the sheet metal to fall into the material frame. This structure enables automatic collection of sheet metal, improving production efficiency and the flexibility of the device.

[0004] During the stamping process, the material is subjected to high pressure friction, which can easily generate fine dust or debris. Especially in the zero-waste net forming process, these particles are easy to adhere to the mold cavity, positioning surface or structural groove. If they are not removed in time, they will not only affect the positioning accuracy of subsequent workpieces, but may also press into the product surface, causing scratches or dimensional deviations. Summary of the Invention

[0005] The purpose of this invention is to provide a stamping die for automotive parts, in order to solve the problem mentioned in the background art that dust in the die cavity and groove is difficult to remove online during the stamping process, resulting in inaccurate positioning and surface defects of the workpiece.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a stamping die for automotive parts, comprising an operating table and a lower die fixedly installed on the upper surface of the operating table. A first moving track is fixedly provided on one side of the operating table at the loading end of the lower die, and a second moving track is fixedly provided on the other side. A pushing mechanism is slidably installed in the first moving track, and a dust blowing mechanism is slidably installed in the second moving track. The pushing mechanism and the dust blowing mechanism are connected by the same gear transmission part and driven synchronously.

[0007] Furthermore, the pushing mechanism includes a push plate slidably disposed within a moving track, a push ring fixedly connected to one side of the push plate, the push ring being located on one side of the lower mold feeding end, and a rubber pad being provided on the pushing side of the push ring facing the workpiece.

[0008] Furthermore, a slider is provided on one side of the push plate. The slider passes through a limiting groove opened on one side wall of the moving track and is fixedly connected to the rack. A roller is installed at the bottom of the push plate to reduce sliding resistance.

[0009] Furthermore, the gear transmission unit includes a rotating gear rotatably mounted on the outside of the moving track, which meshes with a rack. One end of the rotating gear's shaft is fixedly connected to a bevel gear, and a rotating rod is rotatably mounted on the upper surface of the operating table. Two bevel gears are fixedly connected to both ends of the rotating rod, with one end of the bevel gear meshing with the first bevel gear and the other end meshing with a bevel gear rotatably mounted on the side wall of the moving track. The first bevel gear is driven by a motor, and the shaft of the third bevel gear is coaxially fixedly connected to a lead screw. The lead screw is threaded into the bottom of the dust blowing mechanism to convert the rotational motion into linear motion.

[0010] Furthermore, the dust blowing mechanism includes a mounting frame that is slidably disposed within the moving track two. The mounting frame is equipped with blowing pipe one and blowing pipe two in sequence from top to bottom. The nozzle on blowing pipe one faces the interior of the corresponding lower mold, and the nozzle on blowing pipe two faces the planar area of ​​the corresponding lower mold. Both blowing pipe one and blowing pipe two are connected to external blowing equipment through air pipes.

[0011] Furthermore, a downwardly inclined guide plate is hinged to the operating table at the lower mold discharge end. The lower side of the guide plate is hinged to the end of the piston rod of the cylinder, and the bottom of the cylinder body is hinged to the bottom surface of the operating table. This is used to drive the guide plate to flip so as to achieve automatic discharge of the finished product.

[0012] Furthermore, a support frame is fixedly installed at the upper end of the operating table, and a hydraulic cylinder is installed on the support frame. The piston rod end of the hydraulic cylinder is fixedly connected to the upper mold, and the four corners of the upper mold are respectively fitted onto the guide rods fixed on the operating table and slide in cooperation with the guide rods.

[0013] The technical solution provided by this invention has the following advantages compared with the known prior art: This invention achieves automatic ejection of the workpiece after stamping and efficient cleaning of the mold surface and cavity by synchronously driving the pushing mechanism and dust blowing mechanism from the same source. The pushing mechanism uses a push ring with a rubber pad to avoid damaging the workpiece. The dust blowing mechanism is equipped with upper and lower double-layer blowing pipes, which blow air in a directional manner on the mold groove and surface respectively, effectively removing particles and adhering dust generated during the stamping of nylon or engineering plastics. At the same time, the guide plate automatically flips under the drive of the cylinder, facilitating the smooth sliding of the finished product. The upper mold closes precisely through the guide rod, ensuring forming accuracy. The overall structure is compact, highly automated, reduces manual intervention, and improves production efficiency, product consistency, and mold life. Attached Figure Description

[0017] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, 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, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0018] The present invention will be further described below with reference to embodiments.

[0019] Example: A stamping die for automotive parts, such as Figures 1-5 As shown, it includes an operating table 1, on the upper surface of which a lower mold 6 is fixedly installed to support and position the workpiece to be stamped.

[0020] On one side of the loading end of the lower mold 6, a moving track 7 is fixedly installed on the operating table 1, and on the other side, a moving track 9 is fixedly installed. A pushing mechanism is slidably installed in the moving track 7 to push the stamped workpiece out of the lower mold 6. A dust blowing mechanism is slidably installed in the moving track 9 to clean the surface and structural grooves of the lower mold 6. The pushing mechanism and the dust blowing mechanism are connected through the same gear transmission part and driven by a single power source to achieve coordinated action of the two in terms of time and stroke.

[0021] Specifically, the pushing mechanism includes a push plate 10 that is slidably disposed in the moving track 7. A push ring 12 is fixedly connected to the side of the push plate 10 near the lower mold 6. The push ring 12 is located on the outside of the feeding end of the lower mold 6, and a rubber pad 13 is attached to its pushing surface facing the workpiece to buffer the contact force and prevent scratching the surface of the workpiece.

[0022] A slider is provided on one side of the push plate 10. The slider passes through the limiting groove 8 opened on the side wall of the moving track 7 and is fixedly connected to the rack 11. A roller 14 is installed at the bottom of the push plate 10 so that it has less resistance and runs more smoothly when sliding in the moving track 7.

[0023] The gear transmission unit includes a rotating gear 15 rotatably mounted on the outside of the moving track 7. The rotating gear 15 meshes with the rack 11. A bevel gear 16 is fixedly connected to one end of the rotating shaft of the rotating gear 15.

[0024] A horizontal rotating rod is rotatably mounted on the upper surface of the operating table 1 via bearings. Two bevel gears 17 are fixedly connected to both ends of the rotating rod. One end of the bevel gear 17 meshes with a bevel gear 16, while the other end of the bevel gear 17 meshes with a bevel gear 19 rotatably mounted on the side wall of the moving track 9. The bevel gear 16 is driven by a servo motor or a stepper motor.

[0025] After the motor starts, the power is transmitted through bevel gear 16, bevel gear 2 17 and bevel gear 3 19 on the rotating rod to realize the synchronous drive of the two mechanisms. The rotating shaft of bevel gear 3 19 is coaxially and fixedly connected to lead screw 18. Lead screw 18 is threaded with the bottom of the dust blowing mechanism to convert the rotational motion into the linear reciprocating motion of the dust blowing mechanism along the moving track 2 9.

[0026] The dust blowing mechanism includes a mounting frame 20 that is slidably disposed within the moving track 2 9. The mounting frame 20 is fixedly mounted with a first blowing pipe 21 and a second blowing pipe 22 from top to bottom.

[0027] The nozzle of purge pipe 1 21 faces the internal grooves, holes or structural dead corners of the lower mold 6 to remove particles accumulated in the complex cavity. The nozzle of purge pipe 22 faces the planar positioning area of ​​the lower mold 6 to blow away dust adhering to the surface. Both purge pipe 1 21 and purge pipe 22 are connected to an external compressed air source or a central purging device through flexible air pipes. They are opened as needed during the stamping cycle to achieve directional and efficient cleaning.

[0028] In addition, at the discharge end of the lower mold 6, a downwardly inclined guide plate 23 is hinged on the operating table 1. The lower side of the guide plate 23 is hinged to the piston rod end of the cylinder 24, and the bottom of the cylinder body of the cylinder 24 is hinged to the bottom surface of the operating table 1. When the workpiece is pushed out, the cylinder 24 extends and pushes the guide plate 23 to flip to a horizontal or slightly downward inclined position, guiding the finished product to slide into the collection box.

[0029] A support frame 2 is provided above the operating table 1. The support frame 2 is fixed to the upper end of the operating table 1. A hydraulic cylinder 3 is installed on the top of the support frame 2. The piston rod end of the hydraulic cylinder 3 is fixedly connected to the upper mold 4. The four corners of the upper mold 4 are respectively fitted onto the guide rods 5 that are vertically fixed on the operating table 1 and slide with the guide rods 5 to ensure that the upper and lower molds are accurately aligned during the mold closing process, thus ensuring forming accuracy and mold life.

[0030] In summary, firstly, the workpiece to be stamped is placed on the lower die 6. The hydraulic cylinder 3 drives the upper die 4 to descend along the guide rod 5 to complete the stamping process. After stamping, the upper die 4 is reset. Subsequently, the motor is started, driving the bevel gear 16 to rotate, which synchronously drives the pushing mechanism and the dust blowing mechanism through the gear transmission unit. The push plate 10 moves along the first moving track 7 toward the center of the mold, and pushes the finished product out smoothly through the push ring 12 with rubber pad 13. At the same time, the dust blowing mechanism moves along the second moving track 9 toward the mold area. The first blowing pipe 21 and the second blowing pipe 22 blow air in a directional manner to the mold groove and surface to remove the fine dust generated by the stamping. After the blowing and pushing are completed, the cylinder 24 is activated and the guide plate 23 flips, so that the finished product slides down automatically.

[0031] The above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit it. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of the present invention.
