Description

Technical Field

[0001] This utility model belongs to the field of crankshaft signal disc manufacturing technology, and in particular relates to a high-precision guide device for crankshaft signal disc stamping. Background Technology

[0002] The crankshaft signal disc, as one of the core components of the automotive engine control system, is precisely mounted on the engine crankshaft and bears the crucial responsibility of providing crankshaft speed and position information. This information is essential for formulating control strategies such as fuel injection and ignition timing. In the manufacturing process of the crankshaft signal disc, the stamping stage is particularly critical. It not only shapes the final form of the signal disc but also directly affects its dimensional accuracy, shape stability, and surface quality, thus profoundly influencing the overall performance and reliability of the engine.

[0003] In the stamping process of crankshaft signal discs, the guiding device plays a crucial role in ensuring the accuracy and stability of the mold closing. Traditional guiding devices mainly consist of guide posts and guide sleeves. The guide posts are firmly fixed to the lower mold, while the guide sleeves are installed in the upper mold. These two parts, through precise sliding contact, jointly guide the rising and falling movements of the mold, ensuring a smooth and accurate stamping process.

[0004] However, in practical applications, traditional crankshaft signal disc stamping guide devices have gradually revealed a series of defects that cannot be ignored:

[0005] First, in traditional designs, the upper part of the guide post is often suspended in the air, lacking effective support and protection. This design makes the guide post prone to bending or deformation when faced with impacts or wear after long-term use, which in turn seriously affects the mold's closing accuracy and stability, reducing the quality of the stamped parts.

[0006] Secondly, traditional guiding devices mainly rely on guide pillars to guide the edges of the mold, but they are inadequate for guiding the center of the mold. This limited guiding method makes it difficult to ensure the overall stability of the mold during the stamping process, especially when dealing with large or complex-shaped crankshaft signal discs, which may lead to problems such as mold misalignment and deformation.

[0007] Therefore, it is essential to invent a high-precision guide device for crankshaft signal disc stamping. Utility Model Content

[0008] The purpose of this invention is to provide a high-precision guide device for crankshaft signal disc stamping, thereby solving the problems mentioned in the background art.

[0009] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0010] This utility model relates to a high-precision guiding device for crankshaft signal disc stamping, comprising a base, guide columns, a top plate, a lifting frame, positioning columns, and positioning grooves. The base is fixed to the outer side of the lower die of the crankshaft signal disc stamping mold by bolts. Several guide columns are fixed to the upper end of the base by bolts, and the top plate is fixed to the upper end of the guide columns by bolts. A lifting frame is provided between the base and the top plate, wherein the lifting frame is slidably connected to the guide columns, and the lifting frame is fixed to the outer side of the upper die of the crankshaft signal disc stamping mold by bolts. Several positioning columns are fixed to the lower side of the lifting frame by bolts. Positioning grooves corresponding to the positioning columns are formed on the upper side of the base.

[0011] Furthermore, damping plates are slidably installed inside the positioning grooves, and springs are fixed between the lower side of the damping plates and the bottom of the positioning grooves. This arrangement can prevent violent collisions between the upper and lower molds when the crankshaft signal disc stamping mold is closed.

[0012] Furthermore, the lower end of the positioning post and the opening of the positioning groove are both provided with corresponding chamfers, which allows the positioning post to be smoothly inserted into the corresponding positioning groove.

[0013] Furthermore, the top plate includes a frame, a cross, a sliding column, and a mounting plate. The frame is fixed to the upper end of the guide column by bolts, and the cross is fixed inside the frame by welding. The sliding column slides through the center of the cross, and the mounting plate is fixed to the lower end of the sliding column by bolts. The mounting plate is fixed to the upper side of the upper mold of the crankshaft signal disc stamping die by bolts. This arrangement can prevent the guide column from bending and improve the mold closing accuracy of the crankshaft signal disc stamping die.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. The top plate of this utility model has the following advantages: when in use, the frame can connect the upper ends of the guide columns together, thereby preventing the guide columns from bending. Secondly, the cross can strengthen the structural strength of the frame. In addition, when the upper mold of the crankshaft signal disk stamping die is raised or lowered, it can drive the sliding column to slide on the cross accordingly, thereby improving the mold closing accuracy of the crankshaft signal disk stamping die.

[0016] 2. This utility model, through the cooperation of the positioning pin and the positioning groove, can prevent misalignment between the upper and lower molds when the crankshaft signal disc stamping mold is closed. Secondly, through the cooperation of the damping plate and the spring, the movement of the positioning pin inside the positioning groove can be buffered, thereby avoiding violent collisions between the upper and lower molds.

[0027] Specifically, damping plates 8 are slidably installed inside the positioning groove 6. A spring 7 is fixed between the lower side of the damping plate 8 and the bottom of the positioning groove 6. When the positioning post 5 can be slidably inserted into the corresponding positioning groove 6, the movement of the positioning post 5 can be buffered by the cooperation of the damping plate 8 and the spring 7, thereby avoiding violent collision between the upper and lower molds when the crankshaft signal disk stamping mold is closed.

[0028] Specifically, the lower end of the positioning post 5 and the opening of the positioning groove 6 are both provided with corresponding chamfers. With this setting, the positioning post 5 can be smoothly inserted into the corresponding positioning groove 6.

[0029] Specifically, the top plate 3 includes a frame 31, a cross 32, a sliding column 33, and a mounting plate 34. The frame 31 is fixed to the upper end of the guide column 2 by bolts, and the cross 32 is fixed inside the frame 31 by welding. The sliding column 33 slides through the center of the cross 32, and the mounting plate 34 is fixed to the lower end of the sliding column 33 by bolts. The mounting plate 34 is fixed to the upper side of the upper mold of the crankshaft signal disk stamping die by bolts. In use, the frame 31 can connect the upper ends of the guide column 2 together, thereby preventing the guide column 2 from bending. Secondly, the cross 32 can strengthen the structural strength of the frame 31. In addition, when the upper mold of the crankshaft signal disk stamping die is raised or lowered, it can drive the sliding column 33 to slide on the cross 32 accordingly, thereby improving the mold closing accuracy of the crankshaft signal disk stamping die.
