[0002] Cold heading has the advantages of high productivity, high material utilization rate, good surface quality and internal comprehensive performance of parts, and reasonable and continuous metal streamline. Compared with machined parts, the mechanical properties of cold-heading parts can generally be improved by about 10%, and in some cases even up to 20%. The processing efficiency can be more than 50 times, and the material utilization rate can be increased by nearly 100%. Almost more than 80% of the production of fasteners such as bolts, screws, and rivets uses the cold-heading method, which is the preferred process for fastener processing.

[0003] However, the demand for these parts is large. In order to improve the production efficiency of bolts, a tooling die for upsetting bolts is needed to solve this problem. Content of the Utility Model

[0004] To achieve the above object, the utility model provides a tooling die for upsetting bolts, including a vertically arranged die blank. The die blank is cylindrical. A cylindrical first slot is vertically opened in the middle of the upper end of the die blank, and a cylindrical second slot is vertically opened in the middle of the lower end of the die blank. The first slot communicates with the second slot. The aperture of the first slot is 33.5 - 34.5 mm, and the aperture of the second slot is 21 - 22 mm.

[0005] Further, the height of the die blank is 120 - 121 mm, the depth of the first slot is 20 - 21 mm, and the depth of the second slot is 100 mm.

[0006] Further, the diameter of the die blank is 100 - 102 mm.

[0007] Further, the aperture of the first slot is 33.5 mm.

[0008] Further, the aperture of the second slot is 21 mm.

[0009] The advantages of the utility model are as follows: The utility model is not only convenient for staff to operate, but also can quickly change the shape of the processed steel, making it more convenient for the processed steel to be changed into the required bolt shape during the processing, thereby improving the processing efficiency of bolts.

[0010] The following will describe the utility model in detail with reference to the drawings and embodiments. Description of the Drawings

[0018] Embodiment 1

[0019] This embodiment provides as Figure 1 And Figure 2A tooling die for upsetting bolts, as shown, includes a die blank 1 arranged vertically. The die blank 1 is cylindrical, with a height of 120 - 121 mm and a diameter of 100 - 102 mm. The material of the die blank 1 is 45 steel. A cylindrical first slot 2 is vertically opened in the middle of the upper end of the die blank 1, and a cylindrical second slot 3 is vertically opened in the middle of the lower end of the die blank 1. The first slot 2 communicates with the second slot 3. A chamfered frustum with a radius of 2 mm is provided at the connection of the first slot 2 and the second slot 3. The aperture of the first slot 2 is 33.5 - 34.5 mm, and the depth of the first slot 2 is 20 - 21 mm. The aperture of the second slot 3 is 21 - 22 mm, and the depth of the second slot 3 is 100 mm.

[0020] When upsetting bolts, first heat the steel to make it red-hot and softened, then put the steel into the die blank 1 from the first slot 2, and then use a stamping machine to stamp the steel from top to bottom. The bolt blank can be upset, which not only facilitates the operation of the staff but also quickly changes the shape of the processed steel, making it more convenient to change the processed steel into the shape of the required bolt during the processing, thereby improving the processing efficiency of the bolts. Among them, when the aperture of the first slot 2 is 33.5 mm and the aperture of the second slot 3 is 21 mm, the upset bolt blank is the best and most accurate.

[0021] The above content is a further detailed description of the present invention in combination with specific preferred embodiments, and it cannot be determined that the specific implementation of the present invention is only limited to these descriptions. For those of ordinary skill in the technical field to which the present invention belongs, without departing from the concept of the present invention, several simple deductions or substitutions can be made, which should all be regarded as belonging to the protection scope of the present invention.
