Description

Technical Field

[0001] The utility model relates to the technical field of deep groove ball bearing stamping processing, in particular to a deep groove ball bearing stamping die. Background Art

[0002] Deep groove ball bearing (GB / T 276-2003) is the most widely used rolling bearing. It is characterized by low friction resistance and high speed. It can be used for parts that bear radial load or combined load of radial and axial loads at the same time, and can also be used for parts that bear axial loads, such as small power motors, automobile and tractor gearboxes, machine tool gearboxes, general machines, tools, etc.

[0003] When stamping deep groove ball bearings, the bearings and ball bearing cages are often stamped separately before being installed. As a result, the connection strength between the two is not as strong as that of an integrated stamping, which reduces the service life of the deep groove ball bearings. In addition, during the stamping process, the positioning stamping between the upper die and the lower die is also particularly important. Otherwise, the surface of the stamped parts will be uneven, affecting their use and resulting in a large number of defective products. Utility Model Content

[0004] The purpose of the utility model is to provide a deep groove ball bearing stamping die, which solves the technical problems raised in the above background technology.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a deep groove ball bearing stamping die, comprising an upper die and a lower die, the upper die is fixedly mounted on the stamping end, the lower die is fixedly mounted on the stamping table, the inner walls of the upper die and the lower die are respectively fixedly connected with a center column, an inner ring seat and an outer ring seat, a bearing inner ring stamping cavity is formed between the center column and the inner ring seat, a bearing outer ring stamping cavity is formed between the inner walls of the upper die and the lower die and the outer ring seat, a ball bearing retainer stamping cavity is formed between the inner ring seat and the outer ring seat, the inner wall surface of the lower die located between the inner ring seat and the outer ring seat is fixedly connected with a fixed ring seat, and a plurality of spheres replacing the ball positions in the deep groove ball bearing are equidistantly connected to the upper surface of the fixed ring seat;

[0006] The two side surfaces of the upper mold are provided with sliding grooves, and a limiting sliding rod is slidably connected in the sliding groove. The lower rod part of the limiting sliding rod is provided with a threaded surface, and the symmetrical two sides of the upper surface of the lower mold are provided with threaded notches that are adapted to be connected with the threaded surfaces.

[0007] Optionally, a connecting groove plate for firmly connecting to a stamping table is fixedly connected to the lower surface of the lower mold.

[0008] Optionally, a mounting frame for firmly connecting to the punching end is fixedly connected to the central upper surface of the upper mold.

[0009] Optionally, a connecting flange is fixedly connected to the upper surface of the limiting sliding rod.

[0010] Optionally, the central column, the inner ring seat and the outer ring seat are respectively stamped and abutted against each other.

[0011] Optionally, a buffer pad is embedded in the abutting surface of the center column.

[0012] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0013] 1. The utility model designs the center column, inner ring seat, outer ring seat, fixed ring seat and sphere in the lower mold and the upper mold, so that during the stamping process, the stamped parts will be restricted by the center column, inner ring seat, outer ring seat, fixed ring seat and sphere, and an integrated deep groove ball bearing and a bearing cage for fixing the balls are stamped in the stamping cavity of the bearing inner ring, the stamping cavity of the bearing outer ring and the stamping cavity of the ball bearing cage, thereby improving the overall connection strength of the deep groove ball bearing and extending the service life of the product.

[0014] 2. The utility model utilizes the limiting slide bar connected between the lower die and the upper die. When the punching end pushes the upper die close to the lower die for punching, the slide groove of the upper die will slide in the limiting slide bar until it accurately abuts against the surface of the lower die for punching. In this way, the punching range and shape of the stamped parts are limited, ensuring the qualified rate of the stamped finished parts. BRIEF DESCRIPTION OF THE DRAWINGS
