Description

Technical Field

[0001] The utility model relates to a stamping die for processing a ball head screw blank of a press. Background Art

[0002] The ball screw for a press is a key component, connecting the connecting rod and the slider, transmitting kinetic energy. It is commonly processed from round steel or forgings. Due to its unique shape, with a larger-diameter ball at one end and a smaller-diameter screw at the other, round steel profiles must be selected based on the maximum outer diameter of the ball head. This results in significant overall machining allowances, long processing time, and high material consumption. Forgings, on the other hand, are more expensive, have larger local allowances, and result in an uneven shape. Utility Model Content

[0003] The purpose of the utility model is to solve the above deficiencies in the prior art and to provide a stamping die for processing ball head screw blanks for presses.

[0004] A stamping die for processing ball head screw blanks for a press includes a first die and a second die. The first die and the second die are installed on a press. The first die includes a first upper die and a lower die. The lower end face of the first upper die is provided with a first groove for the first stamping of the blank. The cross-sectional shape of the first groove is trapezoidal. The second die includes a second upper die and a lower die. The lower end face of the second die is provided with a second groove for the second stamping of the blank. The cross-sectional shape of the second groove is rectangular.

[0005] Preferably, the first mold and the second mold are made of steel alloy.

[0006] Preferably, the upper end surface of the lower mold is provided with a third groove for fixing the blank.

[0007] Preferably, the blank is a columnar structure.

[0008] Preferably, the press includes a slider and a base, the slider is slidably mounted on the body of the press, the first upper mold and the second upper mold are respectively fixed to the lower bottom surface of the slider by bolts, and the lower mold is fixed to the base by bolts.

[0009] Preferably, a plurality of guide columns are provided between the slider and the base.

[0010] Preferably, an ejection cylinder is provided at the bottom of the second mold.

[0011] Beneficial effects: Compared with the prior art, the utility model pre-processes the blank through the first mold, so that the end of the blank is first turned into the shape of the first groove, and then the blank is punched for the second time through the second mold, so that the end of the blank is turned into the shape of the second groove, completing the processing of the end. The overall processing principle is to press the end of a column to make it flat and thick, and the processing process is realized by a press, which saves material loss and reduces costs.

[0018] In order to deepen the understanding of the present invention, the present invention will be further described in detail below with reference to embodiments and drawings. The embodiments are only used to explain the present invention and do not constitute a limitation on the scope of protection of the present invention.

[0019] like Figure 1-5 As shown, the blank 1, the first mold 2, the second mold 3, the lower mold 4, and the ejection cylinder 5;

[0020] A stamping die for processing ball head screw blanks for a press includes a first die 2 and a second die 3. The first die 2 and the second die 3 are made of steel alloy. The first die 2 and the second die 3 are installed on a press. The press includes a slider and a base. The slider is slidably installed on the body of the press. A plurality of guide columns are provided between the slider and the base. The first die 2 and the second die 3 are used for stamping a blank 1, and the blank 1 is a columnar structure.

[0021] The first mold 2 includes a first upper mold and a lower mold 4. The lower end surface of the first upper mold is provided with a first groove for the first punching of the blank 1, and the cross-sectional shape of the first groove is trapezoidal. The second mold 3 includes a second upper mold and a lower mold 4. The lower end surface of the second mold 3 is provided with a second groove for the second punching of the blank 1, and the cross-sectional shape of the second groove is rectangular. The upper end surface of the lower mold 4 is provided with a third groove for fixing the blank 1. The first upper mold and the second upper mold are respectively fixed to the lower bottom surface of the slider by bolts, and the lower mold 4 is fixed to the base by bolts. An ejection cylinder 5 is provided at the bottom of the second mold 3.

[0022] Instructions for use: First, cut the blank into a cylindrical structure. Heat one end of the blank to 1150°C. Place the blank into the first die of a press and perform the first stamping, so that the shape of the heated end of the blank matches the shape of the upper die of the first die. The lower end surface of the upper die of the first die is provided with a first groove for the first stamping of the blank. The cross-section of the first groove is trapezoidal.

[0023] The blank part 1 that has been stamped for the first time is then placed in the second mold of the press and stamped for the second time, so that the shape of the heated end of the blank part adapts to the shape of the upper mold of the second mold, wherein the lower end face of the upper mold of the second mold is provided with a second groove for stamping the blank part for the second time, and the cross-section of the second groove is rectangular; the blank part 1 that has been stamped for the second time is subjected to normalizing heat treatment, and the normalizing temperature range is 727°C-912°C.

[0024] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
