Abstract
Description
Technical Field
[0001] This utility model relates to the field of stamping technology, and in particular to a high-temperature stamping die holder with multi-level precise positioning. Background Technology
[0002] High-temperature stamping, as an important branch of stamping technology, is mainly used for high-strength metal materials (such as hot-formed steel). By heating the billet to a specific temperature (usually 800-1000℃) to soften it, and then using a die to quickly stamp it into shape and follow-up cooling, the tensile strength and forming accuracy of the workpiece can be significantly improved. It is a core process for producing key components such as automotive safety structural parts and high-end mechanical brackets.
[0003] In the high-temperature stamping production of bracket-type workpieces, some traditional bracket stamping dies have obvious technical limitations: their die bases lack dedicated positioning mechanisms, requiring operators to hold a clamp and place the red-hot workpiece on the die base during production, and then rely on the upper die to press down to complete the stamping. Since workpiece positioning relies entirely on the operator's experience and judgment, firstly, human visual errors or operational vibrations can easily cause the workpiece to shift in position, resulting in precision problems such as out-of-tolerance dimensions and misaligned holes after stamping, thus reducing the product qualification rate; secondly, manual positioning requires repeated adjustments to the workpiece position, leading to a longer stamping cycle and low production efficiency. To solve the above problems, this utility model proposes a high-temperature stamping die base with multi-level precise positioning. Utility Model Content
[0004] The main purpose of this invention is to provide a high-temperature stamping die holder with multi-level precise positioning, which can effectively solve the problems in the background art.
[0005] To achieve the above objectives, the present invention adopts the following technical solution: A high-temperature stamping die base with multi-level precision positioning includes a die base body. Multiple positioning posts are mounted on the upper end of the die base body. A first driving mechanism for moving the workpiece is provided on the die base body. The first driving mechanism includes two first mounting members and two second mounting members disposed on the die base body. An electric push rod is provided on the inner wall of each of the second mounting members. A vertical plate is provided at the output end of each electric push rod. A clamping plate is provided at the upper end of the vertical plate. A rotating shaft is shared by the two first mounting members. A clamping member is fixedly connected to the side wall of the rotating shaft. A second driving mechanism for driving the rotating shaft to rotate is provided on the side wall of one of the first mounting members.
[0006] Preferably, the second drive mechanism includes a protective housing fixedly connected to the side wall of the first mounting component, a motor fixedly connected to the side wall of the protective housing, a rotating rod rotatably connected to the side wall of the first mounting component, and a first gear and a second gear fixedly connected to the side wall of the rotating shaft and the side wall of the rotating rod, respectively.
[0007] Preferably, the first mounting component has an L-shaped cross-section, and a first screw is provided at the bottom of the first mounting component.
[0008] Preferably, the second mounting component has an L-shaped cross-section, and a plurality of second screws are provided at the bottom of the second mounting component.
[0009] Preferably, the side wall of the vertical plate is provided with a connecting strip, the upper end of the connecting strip is fixedly connected to the lower end of the adjacent abutting plate, and the side wall of the connecting strip is provided with two third screws.
[0010] Preferably, the electric push rod has a first connecting plate and a second connecting plate fixedly connected to its two side walls, and both the first connecting plate and the second connecting plate have multiple fourth screws on their side walls.
[0011] Preferably, a shielding plate is fixedly connected to the side wall of the vertical plate, and the shielding plate is inclined.
[0012] Compared with the prior art, the present invention has the following beneficial effects: This device is equipped with a first driving mechanism, where the clamping part realizes the pre-positioning of the front end of the workpiece and the electric push rod realizes the centering of the workpiece, forming a multi-level precise positioning structure. This completely replaces the traditional manual experience positioning method, effectively avoiding the problems of workpiece size deviation and hole misalignment caused by positioning deviation. At the same time, it ensures the positioning consistency of the same batch of workpieces, significantly improving the product qualification rate and quality stability. This device is equipped with a second drive mechanism, which uses a motor to drive the flipping of the clamping parts instead of manually, reducing the chance of operators coming into contact with the high-temperature mold base and high-temperature workpieces, and reducing the risk of burns. This device is equipped with a vertical plate, and the shielding plate on the side wall of the vertical plate can prevent high-temperature slag from damaging the electric push rod, extend the service life of the core components of the equipment, and reduce maintenance costs.

Detailed Implementation
[0015] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.
[0016] like Figure 1-5 As shown, a high-temperature stamping die base with multi-level precision positioning includes a die base body 1, which is a bracket die base in the prior art. Its matching upper die is also in the prior art. Multiple positioning pins 9 are installed on the upper end of the die base body 1. The die base body 1 is provided with a first driving mechanism for driving the workpiece to move. The first driving mechanism includes two first mounting parts 2 and two second mounting parts 5 set on the die base body 1. The inner wall of the second mounting part 5 is provided with an electric push rod 6. The output end of the electric push rod 6 is provided with a vertical plate 7. The upper end of the vertical plate 7 is provided with a pressing plate 8. The two first mounting parts 2 are provided with a rotating shaft 3. The side wall of the rotating shaft 3 is fixedly connected with a pressing part 4.
[0017] One of the first mounting components 2 has a second drive mechanism on its side wall for driving the rotating shaft 3 to rotate. The second drive mechanism includes a protective housing 14 fixedly connected to the side wall of the first mounting component 2. A motor 13 (the output shaft of the motor 13 can rotate in both directions) is fixedly connected to the side wall of the protective housing 14. A rotating rod 12 is rotatably connected to the side wall of the first mounting component 2. A first gear 10 and a second gear 11 are fixedly connected to the side wall of the rotating shaft 3 and the side wall of the rotating rod 12, respectively. By adding the motor 13, the rotating shaft 3 does not need to be rotated manually.
[0018] In this utility model, the first mounting part 2 has an L-shaped cross section, and a first screw is provided at the bottom of the first mounting part 2. The first screw is used to connect the first mounting part 2 to the mold base body 1, so that the first mounting part 2 can be disassembled and the motor 13 can be easily maintained.
[0019] In this utility model, the second mounting part 5 has an L-shaped cross section, and multiple second screws are provided at the bottom of the second mounting part 5. The second screws are used to connect the second mounting part 5 to the mold base body 1, so that the second mounting part 5 can be disassembled for easy maintenance of the electric push rod 6.
[0020] In this utility model, the side wall of the vertical plate 7 is provided with a connecting strip 17. The upper end of the connecting strip 17 is fixedly connected to the lower end of the adjacent abutting plate 8. The side wall of the connecting strip 17 is provided with two third screws. The third screws are used to connect the vertical plate 7 and the abutting plate 8, so that the abutting plate 8 with severe wear can be replaced separately.
[0021] In this utility model, the electric push rod 6 has a first connecting plate 15 and a second connecting plate 18 fixedly connected to its two side walls respectively. The output end side wall of the electric push rod 6 and the base side wall are in contact with the vertical plate 7 and the inner wall of the second mounting part 5 respectively. The side walls of the first connecting plate 15 and the second connecting plate 18 are provided with multiple fourth screws, so that the electric push rod 6 can be disassembled individually.
[0022] In this utility model, a baffle plate 16 is fixedly connected to the side wall of the vertical plate 7. The baffle plate 16 is inclined to prevent slag on the hot workpiece from falling onto the electric push rod 6 during the hot pressing process.
[0023] In the initial state, a controller is set near the worktable of the stamping machine. This controller can control the motor 13 and the electric push rod 6. In the idle position of this device, all the above-mentioned driving components (referring to power elements and electrical components) and the appropriate power supply are connected by wires. The electrical components are electrically connected in the order of operation. The detailed connection method is a well-known technology in the field. The following mainly introduces the working principle and process, and will not explain the electrical control. In addition, the clamping part 4 is rotated clockwise to the right side of the mold base body 1, and the output ends of the two electric push rods 6 retract.
[0024] When in use, before placing the red-hot workpiece onto the mold on the mold base body 1 from left to right, first flip the clamping part 4 so that the clamping part 4 rotates counterclockwise and is placed on the mold. The operator uses clamps to place the red-hot workpiece onto the mold on the mold base body 1 from left to right, with the front end of the workpiece abutting against the side wall of the clamping part 4. Then, the two electric push rods 6 are activated. The output ends of the two electric push rods 6 extend to push the workpiece toward the middle of the mold, positioning it in the middle of the mold. Then, the clamping part 4 is flipped and the output ends of the electric push rods 6 retract, waiting for stamping. During the process, the position of the workpiece can be positioned during the placement process, and the lateral center of the workpiece can be positioned after placement. The rotation of the clamping part 4 does not require manual rotation; it can be driven by starting the motor 13.
[0025] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
