[0023] To make the structure and function of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0024] See the attached Figures 1-6 , a slope-pressing die for a conical bearing cage, comprising an upper die body and a lower die body. The upper die body includes a punch body 1 and a punch 2 detachably mounted on the punch body 1. The punch body 1 is connected to a press. The lower die body includes a base 4, a die body 5 and a die. Two die bodies 5 are oppositely arranged on the base 4, and the die is detachably mounted on the die body 5. The die includes a guide die 17 and a slope-pressing die 6. The guide die 17 and the slope-pressing die 6 are respectively assembled on the two die bodies 5. The surface of the guide die 17 cooperates with and guides the downward pressing action of the punch 2. A slope-pressing part 10 matching the cage window hole structure is formed on the upper part of the slope-pressing die 6. The slope-pressing part 10 cooperates with the punch 2 to punch the cage. First adjusting screw holes 7 for adjusting the angle of the die are provided on the two die bodies 5, and second adjusting screw holes 8 for adjusting the angle of the die body 5 are provided on the base 5. The die is arranged corresponding to the punch 2, and the die forms the window hole structure of the cage.

[0025] Based on the above technical solution, 3 second adjusting screw holes 8 are arranged horizontally on each side.

[0026] Further, an upper handle 3 is provided above the punch body 1, and the punch body 1 and the upper handle 3 are connected to the press by bolts.

[0027] Further, the punch body 1 is a wedge-shaped structure that is wider at the top and narrower at the bottom. Punch mounting grooves 9 are provided on both sides of the punch body 1, and two punches 2 are mounted in the punch mounting grooves 9 on both sides. The punch 2 is in interference fit with the punch body 1. The punch mounting groove 9 is a dovetail groove. The connection method of the dovetail groove has high precision, strong stability, accurate positioning, and the position of the punch 2 is easy to fix, which is beneficial to improving the stamping precision on the basis of being easy to disassemble.

[0028] Further, the die, the die body 5 and the base 4 are connected by bolts to form a lower die body.

[0029] Further, on one side opposite to the female die body 5, a female die installation groove is provided, and through first adjustment screw holes 7 are formed on both side surfaces of the female die installation groove.

[0030] Based on the above technical solution, the bottom of the female die installation groove expands laterally outward, making the groove diameter larger than the width of the female die, reserving a certain space for the adjustment of the first adjustment bolt in the first adjustment screw hole 7.

[0031] Further, the slope pressing part 10 includes a wedge-shaped groove 11 adapted to the cage window beam 14. Window hole fitting bodies 12 are symmetrically arranged on both sides of the wedge-shaped groove 11. Raised portions 13 are provided at the upper and lower ends of the window hole fitting body 12 close to the wedge-shaped groove 11, and the raised portions 13 form relief grooves at the corners of the cage window holes 15.

[0032] Based on the above technical solution, it should be noted that with the technological innovation of the conical cage, new relief grooves have begun to be widely used. When processing with the original slope pressing die, it will cause interference when the "extra material" at the root of the cage window hole contacts the roller, thus affecting the rotation of the bearing. For such products, it is necessary to change the design of the original slope pressing die from the design perspective to avoid interference between the cone cage and the vertex of the roller. The present invention adopts the raised portion 13 structure on the window hole fitting body 12 of the slope pressing part 10, making the new slope pressing female die better match the cage window hole. There will be no "extra material" phenomenon after slope pressing, and the new slope pressing female die will not interfere with the bottom of the cage window hole during processing.

[0033] Further, the upper surface and the lower surface of the window hole fitting body 12 are recessed relative to the upper surface and the lower surface of the slope pressing part 10 to form positioning grooves 16. The surfaces of the two raised portions 13 of the window hole fitting body are flush with the upper surface and the lower surface of the slope pressing part 10. The positioning grooves 16 facilitate positioning the relative position with the cage, avoiding the displacement of the cage, and can improve the stamping accuracy.

[0034] Further, a recessed stamping cavity is formed in the middle of the base 4. The two sides of the stamping cavity are respectively connected with female die bodies 5. The stamping female die 6 and the guiding female die 17 installed on the two female die bodies 5 are arranged oppositely; second adjustment screw holes 8 are respectively provided on both sides of the base 4, and the second adjustment screw holes 8 penetrate through to the surface of the female die body 5 far from the female die, and the angle formed by the two female dies 6 is adjusted through the second adjustment bolts in the second adjustment screw holes 8.

[0035] Based on the above technical solution, each component of the upper die body and the lower die body of the present invention is a detachable structure. The corresponding female die can be replaced according to different cage workpieces to be processed, making the stamping die adapt to conical cages of different specifications. At the same time, the angle of the female die can be adjusted through the first adjustment screw holes 7 and the second adjustment screw holes 8 to make it match the punch and the workpiece, improving the versatility of the die and the stamping accuracy of the die.

[0036] It should be noted that the parts not detailed in the present invention are prior art.

[0037] The above are only the best embodiments of the present invention. Obviously, the present invention is not limited to the above embodiments and there can be many variations. All variations that can be directly derived or associated by those of ordinary skill in the art from the content disclosed in the present invention should be considered within the protection scope of the present invention.
