Abstract
Description
Technical Field
[0001] This utility model relates to the field of automotive parts processing technology, specifically to a stamping die for an automotive cover with a guiding structure. Background Technology
[0002] The car roof, also known as the car cover, is a covering on the top of the car body, located between the windshield and the rear windshield, covering the top area of the driver's cabin and passenger compartment. The car roof is a large, thin sheet covering, mostly made of cold-rolled steel or aluminum alloy, which has good stamping ductility. Therefore, the car roof is formed by stamping with a stamping die.
[0003] Currently, during the stamping process, car roof covers are placed between the fixed mold and the moving mold using a suction cup robotic arm. After being placed, there is a certain degree of misalignment between the sheet and the fixed mold, which affects the forming effect of the car roof cover. Moreover, after stamping, the sheet will be embedded in the groove of the fixed mold, making it difficult to remove and resulting in poor practicality. Utility Model Content
[0004] The purpose of this utility model is to provide a stamping die for an automobile cover with a guiding structure in order to solve the above problems, as detailed below.
[0005] To achieve the above objectives, the present invention provides the following technical solution:
[0006] The present invention provides a car cover stamping die with a guide structure, including a fixed die and a moving die. The fixed die is rotatably connected to all four sides, and the opposite ends of the four guide rods are located outside the fixed die and tilted upward. The fixed die is provided with elastic support members around its perimeter to support the upward movement of the ends of the guide rods. The moving die is provided with telescopic rods at its four corners, and the movable ends of the telescopic rods are detachably connected to the moving die.
[0007] Preferably, the upper surface of the fixed mold is a concave arc surface, and the bottom surface of the moving mold is provided with an extrusion convex surface that matches the concave arc surface.
[0008] Preferably, the fixed mold has grooves on all four sides, and the ends of the four guide rods are rotatably connected to the four grooves respectively. The upper side of the four guide rods is an arc surface design that matches the concave arc surface.
[0009] Preferably, a rubber block that abuts against the guide rod is fixedly connected to the outer side of the inner bottom of each groove.
[0010] Preferably, the elastic support includes a hollow tube rotatably connected to the fixed mold, a movable rod slidably connected in the hollow tube, and the end of the movable rod rotatably connected to the guide rod. A spring is connected between the movable rod and the inner bottom of the hollow tube.
[0011] Preferably, a resistance pad is fixedly connected to the inner wall end of the hollow tube, and friction patterns adapted to the resistance pad are provided on the side wall of the movable rod.
[0012] Preferably, the telescopic rod includes a hollow tube II fixedly connected to the side wall of the fixed mold, and a movable rod II is slidably connected in the hollow tube II. The side wall of the moving mold is provided with a bolted connector that is connected to the end of the movable rod II.
[0013] Preferably, the bolted connector includes a sleeve fixedly connected to the side wall of the moving mold, and the second movable rod is adapted to the inner diameter of the sleeve. The end of the second movable rod is provided with a bolt hole, in which a bolt is threadedly connected, and the closed end of the sleeve is provided with a through hole adapted to the bolt.
[0014] Preferably, the hollow tube is perpendicular to the bottom surface of the fixed mold.
[0015] Preferably, the upper surface of the moving mold is fixedly connected to two mating mounting columns, and the four corners of the fixed mold are provided with mounting holes.
[0016] The beneficial effects are:
[0017] The robotic arm feeds the top cover plate into the gap between the fixed mold and the moving mold. After the plate is lowered, it is appropriately corrected for deviation under the guidance of the tilting guide rods under the action of gravity. Then, the moving mold presses down, causing the four guide rods to move down into the groove, and at the same time, the elastic support members elastically contract. With the cooperation of the fixed mold, the plate is stamped and formed. After the moving mold is raised, the four guide rods bounce upward under the elastic force of the elastic support members, causing the roof cover plate on the fixed mold to bounce up and detach. This allows for appropriate correction of the lowered plate and also enables assisted demolding after stamping the top cover plate, improving practicality. Attached Figure Description

[0026] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be described in detail below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.
[0027] See Figures 1-5 As shown, this utility model provides a stamping die for an automobile cover with a guiding structure, including a fixed die 1 and a moving die 2. Guide rods 6 are rotatably connected to all four sides of the fixed die 1, and the opposite ends of the four guide rods 6 are located outside the fixed die 1 and tilted upward. Elastic support members 3 are provided around the fixed die 1 to support the upward movement of the ends of the guide rods 6. Telescopic rods 4 are provided at the four corners of the moving die 2, and the movable ends of the telescopic rods 4 are detachably connected to the moving die 2.
[0028] As an optional implementation, the upper surface of the fixed mold 1 is a concave arc surface 11, and the bottom surface of the moving mold 2 is provided with an extrusion convex surface 12 that is adapted to the concave arc surface 11, so that the plate can be stamped and formed when the moving mold 2 and the fixed mold 1 are closed.
[0029] Specifically, grooves 7 are provided around the four sides of the fixed mold 1, and the ends of the four guide rods 6 are rotatably connected to the four grooves 7 respectively. The upper side of the four guide rods 6 is an arc surface design that matches the concave arc surface 11. A rubber block 8 that abuts against the guide rod 6 is fixedly connected to the outer side of the inner bottom of each groove 7. When the guide rod 6 retracts into the groove 7, it can perform preliminary elastic compression on the rubber block 8. The guide rod 6 rises by its own elasticity. The arc surface design of the guide rod 6 can make the surface flatter when stamping the cover plate. It is worth mentioning that the surface of the guide rod 6 is a smooth mirror design, which reduces the friction when the plate contacts it, and enables the plate to be finely adjusted on the four guide rods 6 under the action of gravity.
[0030] Reference Figure 3 As shown, the elastic support member 3 includes a hollow tube 301 rotatably connected to the fixed mold 1. A movable rod 302 is slidably connected in the hollow tube 301, and the end of the movable rod 302 is rotatably connected to the guide rod 6. A spring 303 is connected between the movable rod 302 and the inner bottom of the hollow tube 301. A resistance pad 304 is fixedly connected to the inner wall end of the hollow tube 301, and friction patterns 305 adapted to the resistance pad 304 are provided on the side wall of the movable rod 302. When the guide rod 6... After being subjected to downward force, the extrusion rod 302 moves downward in the hollow tube 301, simultaneously causing the spring 303 to contract. When the moving mold 2 rises, the spring 303 elastically unfolds, pushing the extrusion rod 302 and the guide rod 6 upward, causing the upper cover plate to separate from the fixed mold 1. Through the cooperation between the resistance pad 304 and the friction texture 305, the movement resistance of the extrusion rod 302 can be increased, allowing the extrusion rod 302 to slowly lift the guide rod 6, avoiding damage to the upper cover plate caused by the elasticity of the guide rod 6.
[0031] Reference Figure 5 As shown, the telescopic rod 4 includes a hollow tube 401 fixedly connected to the side wall of the fixed mold 1. A movable rod 402 is slidably connected in the hollow tube 401. The side wall of the moving mold 2 is provided with a bolted connector 5 connected to the end of the movable rod 402. The movable rod 402 moves up and down with the moving mold 2. By restricting the movement of the moving mold 2 through the hollow tube 401, the movement of the moving mold 2 can be vertically guided, thereby making the mold closing between the moving mold 2 and the fixed mold 1 more stable.
[0032] As an optional implementation, the bolted connector 5 includes a sleeve 501 fixedly connected to the side wall of the moving mold 2, and the inner diameter of the movable rod 402 is adapted to the sleeve 501. The end of the movable rod 402 is provided with a bolt hole 502, and a bolt 504 is threaded into the bolt hole 502. The closed end of the sleeve 501 is provided with a through hole 503 adapted to the bolt 504. During installation, the movable rod 402 is pulled up so that its end is inserted into the sleeve 501, and then the bolt 504 is inserted into the through hole 503 and the bolt hole 502 at the same time and rotated to complete the connection and fixation between the movable rod 402 and the moving mold 2.
[0033] Specifically, the hollow tube 401 is perpendicular to the bottom surface of the fixed mold 1, which makes the moving mold 2 more stable when it moves vertically up and down.
[0034] Specifically, the upper surface of the moving mold 2 is fixedly connected with two mating mounting posts 9, and the four corners of the fixed mold 1 are provided with mounting holes 10. The moving mold 2 can be installed to the drive end of the machine tool through the mating mounting posts 9, and the fixed mold 1 can be installed on the base through the mounting holes 10.
[0035] The working principle of this utility model:
[0036] In use, the moving mold 2 is installed to the drive end of the machine tool through the mounting column 9, and the fixed mold 1 is installed on the base through the mounting hole 10. The movable rod 402 of the telescopic rod 4 is inserted into the sleeve 501 and fixed by bolt 504. At this time, the moving mold 2 is lifted by the drive end of the machine tool. The robot sends the top cover plate into the gap between the fixed mold 1 and the moving mold 2. After the plate is lowered, the offset is appropriately corrected by the tilting guide rod 6 under the action of gravity. Then the moving mold 2 presses down and drives the four guide rods 6 to move down into the groove 7, and at the same time drives the elastic support 3 to elastically contract. With the cooperation of the fixed mold 1, the plate is stamped and formed. After the moving mold 2 is raised, the four guide rods 6 bounce upward under the elastic force of the elastic support 3, and drive the roof cover plate on the fixed mold 1 to bounce up and detach.
[0037] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
