Description

Technical Field

[0001] This utility model relates to the field of mechanical manufacturing technology, and in particular to a progressive die for producing guide rings for automobiles. Background Technology

[0002] Progressive dies used to produce guide rings for automobiles are dies used in the manufacture of automotive parts for the efficient and precise production of guide rings. They are typically composed of guide pillars and guide sleeves. Their function is to ensure that the upper and lower die bases can be accurately aligned and guided during the opening and closing of the die, to ensure the accuracy of the stamping process, to prevent the die from skewing, and thus to ensure the dimensional accuracy and geometric tolerances of the produced guide rings.

[0003] In the prior art, such as patent CN206046810U, a progressive die for producing guide rings for automobiles is proposed, including an upper die and a lower die. The upper die and the lower die cooperate with each other to form a die cavity. The upper die includes, from bottom to top, an upper die base, an upper pad, an upper clamping plate, an upper stripper back plate, and an upper stripper plate. This utility model has a reasonable design and high efficiency. The die cavity formed by the upper die and the lower die can realize the processes of punching guide holes, cutting waste, first stretching, second stretching, flanging pre-punching, flanging, side grooving, and waste cutting in one go. At the same time, the guiding accuracy is high and the stamping is stable, which can ensure the dimensional and appearance quality of the product.

[0004] However, uneven distribution of raw materials in some parts of the device can cause differences in density and microstructure across different sections of the guide ring. Areas with accumulated raw materials have higher density, while areas with gaps have lower density. This leads to inconsistencies in the mechanical properties of the guide ring, such as strength, hardness, and toughness. During vehicle operation, different parts of the guide ring experience varying pressures and frictional forces. Utility Model Content

[0005] The purpose of this invention is to overcome the shortcomings of existing technologies and provide a progressive die for producing guide rings for automobiles. This die ensures that the raw material evenly fills all cavities and corners, preventing uneven material accumulation or localized gaps. This helps ensure the dimensional accuracy and performance consistency of all parts of the guide ring, facilitates the rapid identification of suitable stamping positions and pressure points, and reduces debugging time and costs. Technicians can flexibly adjust the height according to actual conditions.

[0006] To achieve the above objectives, a progressive die for producing guide rings for automobiles is provided, comprising a lower die, a plurality of support columns fixedly connected to the top of the lower die, an upper die slidably connected to the top of the support columns, a gantry fixedly connected to the top of the upper die, a toothed chain rotatably connected to the top of the gantry, a third gear meshing with the inside of the toothed chain, a drive rod fixedly connected inside the third gear, and a motor fixedly connected to the output end of the drive rod.

[0007] According to the progressive die for producing guide rings for automobiles, the toothed chain has two fourth gears internally meshing, and the fourth gears have a threaded rod internally threadedly connected to the bottom of the threaded rod, with a pressure ring fixedly connected to the bottom.

[0008] According to the progressive die for producing guide rings for automobiles, the top of the upper die is fixedly connected to a feed port, and the support column is rotatably connected to a bearing.

[0009] According to the progressive die for producing guide rings for automobiles, a plurality of first racks are fixedly connected to the bottom of the lower die, and a first gear is externally meshed with the first racks.

[0010] According to the progressive die for producing guide rings for automobiles, a rotating rod is fixedly connected inside the first gear, and a second gear is fixedly connected outside the rotating rod.

[0011] According to the progressive die for producing guide rings for automobiles, the top of the second gear is meshed with a second rack, and a connecting rod is fixedly connected to the outside of the second rack.

[0012] According to the progressive die for producing guide rings for automobiles, a sliding plate is fixedly connected inside the connecting rod, and an electric push rod is fixedly connected outside the sliding plate.

[0013] According to the progressive die for producing guide rings for automobiles, a first protective shell is slidably connected to the outside of the first rack, a base is fixedly connected to the bottom of the first protective shell, a plurality of second protective shells are fixedly connected to the top of the base, the inside of the second protective shell is slidably connected to the outside of the second rack, the top of the base is fixedly connected to the bottom of the electric push rod, and a limit groove is formed inside the base.

[0014] Beneficial effects:

[0015] 1. Driven by a motor at the top of the gantry frame, the drive rod rotates the external third gear, which in turn rotates the external gear chain. This gear chain then rotates the fourth gears on both sides, which in turn rotate the internal threaded rod. The threaded rod then moves the bottom pressure ring, compacting it against the mold filled with raw material. This ensures that the raw material evenly fills all cavities and corners of the mold, preventing uneven material accumulation or localized gaps. This helps ensure the dimensional accuracy and performance consistency of all parts of the guide ring.

[0016] 2. Driven by an electric push rod, the sliding plate at one end of the lower mold moves. The sliding plate moves the internal connecting rod, which in turn moves the second racks on both sides. The second racks drive the second gear at the bottom to rotate, which in turn drives the internal rotating rod to rotate. The rotating rod then drives the external first gear to rotate, causing the first gear to move the external first rack, thus adjusting the height of the top mold. This helps to quickly find the appropriate stamping position and pressure point, reducing debugging time and costs. Technicians can flexibly adjust the height according to the actual situation.
