Description

Technical Field

[0001] This utility model relates to the field of automotive parts processing technology, specifically to a stamping die for automotive body panels. Background Technology

[0002] Automotive parts manufacturing is a crucial foundation of the automotive industry, and its processing efficiency and precision directly impact the quality and cost of automotive products. With the development of new-generation information technologies such as artificial intelligence and big data, intelligent machining systems are being increasingly widely applied in the automotive mold manufacturing field. Intelligent CNC machining systems, by introducing advanced technologies such as intelligent programming and adaptive control, improve mold processing accuracy and efficiency. Automotive body panels refer to surface or internal parts made of thin metal sheets that cover the engine, chassis, and form the cab and body. They can be categorized into three types based on function and location: external body panels, internal body panels, and frame body panels. They differ from general stamped parts in terms of process design, mold processing, equipment selection, and quality control (dimensional tolerances, shape accuracy, part rigidity, surface quality).

[0003] When stamping automotive body panels, hydraulic devices are generally used to control the upper die to stamp the raw material in the lower die. Since automotive body panels are generally large in volume, the lower die is also generally large in volume. If the lower die is not fixed during the stamping process, it may shift during the stamping process, which may further affect the accuracy and efficiency of product production.

[0004] Therefore, we propose a stamping die for automotive body panels. Utility Model Content

[0005] The purpose of this invention is to provide a stamping die for automotive body panels to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a stamping die for automotive body panels, including a base plate, a processing cavity placed on top of the base plate, a fixing component installed on top of the base plate, the fixing component being used to fix the position of the processing cavity in the middle of the upper surface of the base plate, the fixing component being able to prevent the automotive parts from shifting during stamping production, thus affecting product quality, and an auxiliary component, the auxiliary component also installed on top of the base plate, the auxiliary component being used to initially stabilize the position of the processing cavity, the auxiliary component being able to assist the fixing component in fixing the position of the processing cavity.

[0007] Preferably, the fixing component includes guide grooves, and there are two sets of guide grooves. Both sets of guide grooves are opened on the upper surface of the base plate. Each guide groove has a moving block engaged inside. The bottom surface of each set of moving blocks is fixedly connected to a connecting plate. A forward and reverse motor is fixedly connected to the left side of the bottom surface of the base plate. The output shaft of the forward and reverse motor is fixedly connected to a forward and reverse threaded rod. The forward and reverse threaded rod is threadedly connected to the two connecting plates.

[0008] Preferably, the threads on the surfaces of the positive and negative threaded rods are symmetrical about the center line of their surfaces.

[0009] Preferably, the bottom surface of the base plate is fixedly connected to several fixing plates, each of which is rotatably connected to a positive and negative threaded rod.

[0010] Preferably, the auxiliary component includes four locking rods, each locking rod engaging with a moving block. A set of slots is provided on the left and right sides of the processing cavity, the size and position of each slot being adapted to the size of the locking rod. A circular plate is fixedly connected to the end of each locking rod away from the processing cavity, and a spring is fixedly connected between each circular plate and the surface of the moving block.

[0011] Preferably, mounting plates are fixedly connected to both the front and rear sides of the upper surface of the base plate. A pressing rod is placed between the adjacent sides of two mounting plates, and an elastic steel plate is fixedly connected between the side of each pressing rod and the side of the elastic steel plate adjacent to it. Preferably, a set of guide posts is fixedly connected to the opposite sides of the two pressing rods, and each guide post is slidably connected to its corresponding mounting plate.

[0012] Preferably, the bottom surface of the base plate is fixedly connected to four support legs, and the four support legs are distributed in a rectangular shape about the bottom surface of the base plate.

[0013] This utility model has at least the following beneficial effects:

[0014] 1. When stamping automotive body panels, first place the appropriate processing cavity above the base plate. Then, turn on the power switch connected to the forward and reverse motors to make the output shaft of the motors rotate in the forward direction. This will cause the forward and reverse threaded rods fixedly connected to the motors to rotate synchronously. This will cause the two connecting plates threaded to the forward and reverse threaded rods to move towards each other. Then, under the guidance of the guide groove, the two moving blocks can move towards each other, thus firmly fixing the position of the processing cavity.

[0015] By setting up a fixing component, the entire device can be easily fixed in position for use in processing cavities of different sizes. This effectively prevents the automotive body panels from shaking during stamping, which could affect product quality.

[0016] 2. When the processing cavity is placed on the surface of the base plate, the extrusion rod allows the processing cavity to be positioned approximately in the middle of the upper surface of the base plate. The elastic steel plate allows the extrusion rod to move back and forth, thus accommodating processing cavities of different sizes. Next, the clamping rod should be inserted into its corresponding slot to limit the position of the processing cavity and prevent it from shifting when the position of the processing cavity is firmly fixed. When the two moving blocks move towards each other, the clamping rod, under the influence of the spring force, will remain inside the slot, thus firmly fixing the position of the processing cavity in the middle of the upper surface of the base plate.

[0017] By setting auxiliary components, the position of the machining cavity can be fixed in the middle of the surface of the base plate, which can prevent the cover material inside the machining cavity from being deflected during subsequent processing. Attached Figure Description

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] See also Figures 1-4 This utility model provides a technical solution:

[0025] Example 1: A stamping die for automotive body panels includes a base plate 3, a processing cavity 15 placed on top of the base plate 3, a fixing component 1 installed on top of the base plate 3, the fixing component 1 being used to fix the position of the processing cavity 15 in the middle of the upper surface of the base plate 3, the fixing component 1 being used to prevent the automotive parts from shifting during stamping production, thus affecting the product quality, and an auxiliary component 2 installed on top of the base plate 3, the auxiliary component 2 being used to initially stabilize the position of the processing cavity 15, and the auxiliary component 2 being used to assist the fixing component 1 in fixing the position of the processing cavity 15.

[0026] The fixing component 1 includes guide grooves 4, which have two sets. Both sets of guide grooves 4 are opened on the upper surface of the base plate 3. Each guide groove 4 has a moving block 5 locked inside. The bottom surface of each set of moving blocks 5 is fixedly connected to a connecting plate 6. A forward and reverse motor 7 is fixedly connected to the left side of the bottom surface of the base plate 3. The output shaft of the forward and reverse motor 7 is fixedly connected to a forward and reverse threaded rod 8. The forward and reverse threaded rod 8 is threadedly connected to the two connecting plates 6.

[0027] The threads on the surface of the positive and negative threaded rod 8 are symmetrical about the center line of its surface. Several fixing plates 9 are fixedly connected to the bottom surface of the base plate 3. Each fixing plate 9 is rotatably connected to the positive and negative threaded rod 8 to make the positive and negative threaded rod 8 more stable when rotating.

[0028] When stamping automotive body panels is required, first place the appropriate processing cavity 15 above the base plate 3. Then, turn on the power switch that is electrically connected to the forward and reverse motor 7, so that the output shaft of the forward and reverse motor 7 rotates in the forward direction. At this time, the forward and reverse threaded rods 8 that are fixedly connected to the forward and reverse motor 7 can rotate synchronously. Then, the two connecting plates 6 that are threadedly connected to the forward and reverse threaded rods 8 can move towards each other. Then, under the guidance of the guide groove 4, the two moving blocks 5 can move towards each other. At this time, the position of the processing cavity 15 can be firmly fixed.

[0029] By setting the fixing component 1, the device can be easily fixed in position for processing cavity 15, and can be used to fix processing cavities 15 of different sizes. This can effectively prevent the automotive body panels from shaking during stamping, which would affect the product quality.

[0030] In embodiment 2, auxiliary component 2 includes four locking rods 17, each locking rod 17 engaging with the moving block 5. A set of slots 16 are provided on the left and right sides of the processing cavity 15, and the size and position of each slot 16 are adapted to the size of the locking rod 17. A circular plate 18 is fixedly connected to the end of each locking rod 17 away from the processing cavity 15, and a spring 19 is fixedly connected between each circular plate 18 and the surface of the moving block 5.

[0031] Mounting plates 11 are fixedly connected to both the front and rear sides of the upper surface of the base plate 3. An extrusion rod 12 is placed between the sides of the two mounting plates 11 that are close to each other. An elastic steel plate 13 is fixedly connected between each extrusion rod 12 and the side of the elastic steel plate 13 that is close to each other.

[0032] Each of the two extrusion rods 12 has a set of guide posts 14 fixedly connected to the side of each rod that is far apart from each other. Each guide post 14 is slidably connected to its corresponding mounting plate 11 to guide the back and forth movement of the extrusion rods 12 and prevent the extrusion rods 12 from tilting up during use.

[0033] Four support legs 10 are fixedly connected to the bottom surface of the base plate 3. The four support legs 10 are arranged in a rectangle about the bottom surface of the base plate 3 and are used to support the entire device.

[0034] When the processing cavity 15 is placed on the surface of the base plate 3, the extrusion rod 12 allows the processing cavity 15 to be positioned approximately in the middle of the upper surface of the base plate 3. The elastic steel plate 13 allows the extrusion rod 12 to move back and forth, thus accommodating processing cavities 15 of different sizes. Next, the clamping rod 17 should be inserted into its corresponding slot 16 to limit the front and back position of the processing cavity 15 and prevent displacement when the position of the processing cavity 15 is firmly fixed. When the two moving blocks 5 move towards each other, the clamping rod 17 can remain inside the slot 16 under the influence of the spring force 19, thus firmly fixing the position of the processing cavity 15 in the middle of the upper surface of the base plate 3.

[0035] By setting the auxiliary component 2, the position of the processing cavity 15 can be fixed in the middle of the upper surface of the base plate 3, which can prevent the cover material in the processing cavity 15 from being deflected during subsequent processing.
