Description

Technical Field

[0001] This invention relates to the field of stamping die technology, specifically to a stamping die for an automobile engine hood. Background Technology

[0002] Patent CN211564221U discloses a stamping die for an automobile hood, relating to the field of molds. This stamping die includes a bottom die, with an upper die placed above it. The upper surface of the upper die has two sets of symmetrical limiting holes. The upper die is mounted to a driving stamping device. The driving device pushes the upper die downwards, placing the material on a central die assembly. The material is then stamped by pressing down on the material.

[0003] In the prior art, the top die is installed with the driving stamping device so that it can generate downward stamping force. The driving device then pushes the top die downward to place the material on the central die. The material is then stamped by pressing down on the top die. When the stamping material is transported to the die, the workpiece is usually moved to the stamping area on the die by a robotic arm. However, the opening range of the stamping area of ​​the die is small, and it is not easy for the robotic arm to transport and move the workpiece to the stamping area.

[0004] Therefore, a stamping die for an automobile engine hood is proposed to solve the problems mentioned above. Summary of the Invention

[0005] To achieve the above objectives, the present invention provides the following technical solution: A base is included, with an inwardly recessed mounting groove formed at the bottom of the base; a driver is bolted to the top of the base, the moving end of the driver is fixedly connected to the top of the upper die, the bottom of the upper die is fixedly connected to the moving end of a guide rod, and the lower fixed end of the guide rod is fixedly connected to the base; a lower die is fixedly connected below the upper die and is mounted on the base; the left and right ends of the top of the lower die are inwardly recessed to form embedding grooves; a conveying assembly is provided within the mounting groove; the conveying assembly includes a connecting seat, a linear driver is bolted to the mounting groove, the moving end of the linear driver is connected to the connecting seat and drives the connecting seat to move up and down along the Y-axis; a pulley is rotatably connected to the connecting seat, and two sets of pulleys are connected via belt drive; a servo motor for driving one set of pulleys to rotate is bolted to the connecting seat; multiple sets of limiting components are connected to the belt, and these multiple sets of limiting components are used for contact with the four corners of the stamped workpiece plate.

[0006] Preferably, an annular permanent magnet is embedded in the side wall of the pulley.

[0007] Preferably, the mounting slot is provided with auxiliary components, and a first electric push rod is bolted to the mounting slot; the first electric push rod is connected to the force-bearing frame, and a placement plate is fixedly connected to the mounting slot; a supplementary light and a shooting component are provided on the placement plate.

[0008] Preferably, the limiting component includes a contact frame, the bottom of which is fixedly connected to the belt; a guide frame is fixedly connected inside the contact frame, a spring is fixedly connected to the bottom of the guide frame, and the other end of the spring is fixedly connected to the repulsion plate.

[0009] Preferably, a connecting rod is rotatably connected to the side wall of the repulsion plate, and the other end of the connecting rod is rotatably connected to the slide rod; the lower end of the slide rod is slidably connected to the outer end of the embedded rod, and the embedded rod is fixedly set on the outer side wall of the guide frame.

[0010] Preferably, a sloping plate is fixedly connected to the top of the contact frame, and a contact plate is slidably connected to the upper end of the slide rod; the upper end of the contact plate is fixedly connected to the corner frame; an auxiliary spring is fixedly connected to the upper side wall of the slide rod, the other end of the auxiliary spring is fixedly connected to the contact plate, and the end of the contact plate contacts the side wall of the sloping plate.

[0011] Preferably, when the contact frame moves to the pulley near the feeding area, the permanent magnet on the pulley repels the repulsion plate. The repulsion plate drives the corner frame to move outward through the connecting rod, increasing the distance between the two sets of corner frames. This makes it easier for the external robotic arm to place the four corners of the stamped sheet on the four sets of corner frames. Then, the contact frame moves away from the pulley, the corner frames reset and move to squeeze the four corners of the stamped sheet, improving the stability of the stamped sheet during conveying.

[0012] Preferably, the belt is provided in two sets, and the two sets of belts are respectively arranged at the left and right ends of the mounting groove, and two sets of limiting components are symmetrically arranged on the belt.

[0013] Preferably, two sets of limiting components form a limiting unit, and multiple sets of limiting units are on the belt.

[0014] Preferably, the pulleys at the left and right ends of the mounting slot are connected by an output shaft.

[0015] Compared with the prior art, the present invention provides a stamping die for an automobile engine hood, which has the following beneficial effects: 1. By setting the conveying component in the mounting groove of the base, the belt can drive the workpiece to move horizontally during conveying without the need for an external robotic arm to extend into the narrow space between the upper and lower molds. This avoids the risk of the robotic arm colliding with the mold due to space limitations and improves the safety of loading and unloading.

[0016] 2. This invention utilizes the permanent magnets on the side wall of the pulley and the embedded groove to generate magnetic repulsion with the repulsion plate in the limiting component, which facilitates the automatic expansion and resetting clamping of the corner frame during material conveying and stamping. When the permanent magnet on the pulley engages with the repulsion plate in the limiting assembly, the corner frame automatically expands outward, making it convenient to place the stamped part in the four sets of corner frames. The belt moves and then the corner frames reset to clamp the four corners of the stamped part. When the permanent magnet on the embedded slot generates magnetic repulsion with the repulsion plate in the limiting component, the corner frame expands outward and loses its clamping force on the stamping part, making it easier to stamp. After stamping, the corner frame clamps and restricts the four corners of the stamped workpiece, making it easier to clamp and move the stamped workpiece.

[0017] 3. The linear actuator in this invention can drive the entire belt to move downward, so that the area above the belt sinks into the embedded groove. During the stamping process, the belt avoids the downward pressing path of the upper die, and the magnetic force in the embedded groove can trigger the corner frame to expand outward again, automatically releasing the workpiece and allowing it to fall smoothly into the stamping area of ​​the lower die.

[0018] 4. By setting auxiliary components below the belt, the present invention forms a layered conveyor system. After stamping, the finished workpiece falls through the hollow area of ​​the force frame to the lower auxiliary component for external delivery, while the scrap remains on the upper belt and continues to the recycling area. The online automatic separation of stamped parts and scrap greatly improves the efficiency of the production line. Attached Figure Description

[0021] 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 embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0022] Please see Figures 1-4 In this embodiment, a car engine hood stamping die includes a base 1, with an inwardly recessed mounting groove 2 at the bottom of the base 1. Please see Figures 1-4 The top of the base 1 is bolted with a driver 3. The moving end of the driver 3 is fixedly connected to the top of the upper mold 4. The driver 3 is used to drive the upper mold 4 to move up and down. The upper mold 4 moves up and down with the assistance of the guide rod 5, which improves the stability of the upper mold 4 when it moves. The bottom of the upper mold 4 is fixedly connected to the moving end of the guide rod 5, and the fixed end of the guide rod 5 is fixedly connected to the base 1. More specifically, the guide rod 5 consists of a telescopic rod, in which the outer rod and the inner rod slide together.

[0023] Please see Figures 1-4 The lower mold 6 is fixedly connected to the lower mold 4. The lower mold 6 is bolted to the base 1. The lower mold 6 and the upper mold 4 cooperate with each other. When the upper mold 4 moves down to contact the lower mold 6, the lower mold 6 and the upper mold 4 together stamp the workpiece to form the workpiece. The lower mold 6 has indented grooves 61 at its top left and right ends, which facilitates the downward movement of the area above the belt 73 into the grooves 61. The upper and lower ends of the belt 73 are located at the upper and lower ends of the grooves 61, respectively.

[0024] Please see Figures 1-4 The mounting slot 2 is equipped with a conveying component 7, which is used to convey the stamped workpiece, preventing the workpiece from being moved above the lower die 6 by the external robotic arm, and preventing it from colliding with the mold due to the size of the space between the lower die 6 and the upper die 4, thus facilitating the sequential conveying of the workpiece. Please see Figures 3-7The conveying assembly 7 includes a connecting seat 71, and a linear driver is bolted to the mounting groove 2. The moving end of the linear driver is connected to the connecting seat 71 and drives the connecting seat 71 to move up and down along the Y-axis, and is used to adjust the height of the belt 73. Please see Figures 1-4 A pulley 72 is rotatably connected to the connecting seat 71, and the two sets of pulleys 72 are connected by a belt 73. Please see Figures 1-4 A servo motor 75 for driving a set of pulleys 72 to rotate is bolted to the connecting seat 71. The output shaft of the servo motor 75 is fixedly connected to the shaft of the set of pulleys 72, which drives the set of pulleys 72 to rotate, thus providing power for the operation of the belt 73. The belt 73 is connected to multiple sets of limiting components 74, which are used to make contact with the four corners of the stamped workpiece plate. Please see Figures 1-4 A ring-shaped permanent magnet is embedded in the side wall of the pulley 72. The permanent magnet is arranged in a ring and surrounds the outer peripheral wall of the pulley 72. The permanent magnet is used to generate repulsion with the repulsion plate 743 and push the repulsion plate 743 to move. A magnet is provided at the bottom of the repulsion plate 743, and the magnet is used to generate repulsion force with the permanent magnet.

[0025] Please see Figure 7 The mounting slot 2 is equipped with an auxiliary component 76, which is a belt conveyor to facilitate the conveying of the formed workpiece. The auxiliary component 76 is located below the upper area of ​​the belt 73 and forms an upper and lower layered conveying, which can complete the separation and conveying of the stamped workpiece and the waste material. Please see Figure 2 The mounting slot 2 is bolted with a first electric push rod 77, which is connected to the force-bearing frame 78. The middle area of ​​the force-bearing frame 78 is hollow, and the shape of the force-bearing frame 78 matches the shape of the edge scrap after the workpiece is stamped. Among them, a placement plate 79 is fixedly connected to the mounting slot 2, and a fill light and shooting components are provided on the placement plate 79; Please see Figure 6 and Figure 7 The limiting component 74 includes a contact frame 741, the bottom of which is fixedly connected to a belt 73, and the belt 73 is used to drive the contact frame 741 to move. Please see Figure 7 A guide frame 742 is fixedly connected inside the contact frame 741. A spring 7431 is fixedly connected to the bottom of the guide frame 742. The spring 7431 provides power for the movement and reset of the repulsion plate 743. The other end of the spring 7431 is fixedly connected to the repulsion plate 743. The lower end of the repulsion plate 743 is slidably connected inside the guide frame 742 to provide a limiting effect for the repulsion plate 743. Please see Figure 7A connecting rod 744 is rotatably connected to the side wall of the repulsion plate 743. The other end of the connecting rod 744 is rotatably connected to the slide rod 746. The lower end of the slide rod 746 is slidably connected to the outer end of the embedded rod 745. The embedded rod 745 is fixedly installed on the outer side wall of the guide frame 742. Please see Figure 6 The top of the contact frame 741 is fixedly connected to the inclined plate 747, and the upper end of the slide rod 746 is slidably connected to the contact plate 748. The upper end of the contact plate 748 is fixedly connected to the corner frame 749. Please see Figure 6 An auxiliary spring is fixedly connected to the upper side wall of the slide rod 746. The other end of the auxiliary spring is fixedly connected to the contact plate 748. The end of the contact plate 748 contacts the side wall of the inclined plate 747. A ball bearing is movably provided in the contact area between the contact plate 748 and the inclined plate 747. The ball bearing improves the sliding effect of the contact plate 748. When the contact plate 748 slides on the inclined plate 747, the contact plate 748 is moved by the inclined surface on the inclined plate 747. For example, when the contact frame 741 moves to the pulley 72 near the feeding area, the permanent magnet on the pulley 72 repels the repulsion plate 743. The repulsion plate 743 drives the corner frame 749 to move outward through the connecting rod 744, increasing the distance between the two sets of corner frames 749. This makes it easier for the external robotic arm to place the four corners of the stamped sheet on the four sets of corner frames 749. Then the contact frame 741 moves away from the pulley 72, and the corner frames 749 reset and move to squeeze the four corners of the stamped sheet, improving the stability of the stamped sheet during conveying. Please see Figures 1 to 4 The belt 73 is provided in two sets, and the two sets of belts 73 are respectively set at the left and right ends of the mounting groove 2. Two sets of limiting components 74 are symmetrically provided on the belt 73, and the two sets of limiting components 74 form a limiting unit. There are multiple sets of limiting units on the belt 73. The workpieces are conveyed sequentially using multiple sets of limiting units. The pulleys 72 at both ends of the mounting slot 2 are connected by an output shaft.

[0026] For example, during use, when the external robot clamps the workpiece and moves it above the limiting component 74 on the belt 73, the two sets of limiting components 74 are located above the pulley 72. The permanent magnet on the pulley 72 repels the repulsion plate 743, pushing the repulsion plate 743 to move upward. The repulsion plate 743 drives the connecting rod 744 to move, the connecting rod 744 drives the sliding rod 746 to move, and the sliding rod 746 drives the corner frame 749 to move outward. When the corner frame 749 moves, the contact plate 748 slides on the inclined plate 747. The contact plate 748 pushes the corner frame 749 to move in direction B through the cooperation of the auxiliary spring, so that the corner frame 749 moves outward obliquely. At this time, the distance between the two corner frames 749 increases, and then the robot contacts the four corners of the workpiece with the four sets of corner frames 749. The pulley 72 drives the belt 73 to rotate, and the belt 73 drives the corner frames 749 to move away from the pulley 72. The spring 7431 drives the repulsion plate 743 to reset and move. The repulsion plate 743 drives the corner frames 749 to reset through the connecting rod 744. The two sets of corner frames 749 clamp and restrict the two ends of the workpiece, so that the workpiece can be stably restricted on the belt 73 and the four sets of corner frames 749. The belt 73 moves the workpiece above the lower die 6. Then the linear drive moves the connecting seat 71 downward. The connecting seat 71 moves the belt 73 downward. The belt 73 moves downward into the embedding groove 61. At the same time, the permanent magnet in the embedding groove 61 repels the repulsion plate 743. The multiple sets of repulsion plates 743 can also move the four sets of corner frames 749 outward, so that the clamping of the four sets of corner frames 749 on the workpiece disappears, and the workpiece is located in the stamping area of ​​the lower die 6. Then, the driver 3 drives the upper die 4 to move downward. The upper die 4 moves downward and contacts the workpiece. Through the cooperation of the lower die 6, the workpiece is stamped. After the workpiece is stamped, the residual waste at its edges is squeezed into the top area of ​​the lower die 6. After the upper mold 4 moves upward, the linear driver drives the connecting seat 71 to move upward, the connecting seat 71 drives the belt 73 to move upward, the corner frame 749 on the belt 73 resets and moves and can restrict the four corners of the workpiece, the belt 73 continues to move and drives the limiting component 74, the limiting component 74 drives the workpiece away from the area of ​​the lower mold 6. When the workpiece moves above the placement plate 79, the workpiece is photographed and recorded by the supplementary light and the imaging component set on the placement plate 79. When the workpiece moves above the force-bearing frame 78, the first electric push rod 77 drives the force-bearing frame 78 to move upward, and the force-bearing frame 78 contacts the waste edge of the workpiece. Then, the cutter set above the force-bearing frame 78 is controlled to move downward, and the cutter squeezes and cuts the waste of the workpiece. After the workpiece is cut, it falls downward through the gap in the middle of the force-bearing frame 78 to the auxiliary component 76. The auxiliary component 76 moves and conveys the workpiece to the outer end. Then the cutter and the force-bearing frame 78 move and reset, and the belt 73 drives the waste material stuck on the four sets of corner frames 749 to continue moving. When the corner frame 749 moves to the area of ​​the pulley 72, the corner frame 749 loses its restriction on the waste material, making it easier for the subsequent waste material to be removed from the belt 73 and transported to the recycling area.
