The above-mentioned forging method requires a cylindrical raw material whose diameter is greater than the height of the outer cylinder of the fitting and whose length is consistent with the total length of the fitting in the middle of the fuse for forging, and one raw material only forges one workpiece, while the fitting The diameter of the connecting cylinder 2 and the width of the flat fitting 3 are much smaller than the height of the outer cylinder of the fitting, which leads to material waste; Only by secondary forging can the metal fittings connect the cylinder 2 and the flat fittings 3, which is prone to breakage, especially for the flat fittings 3, whose size is much smaller than that far away. Correspondingly, the forged The number of times is the most, and correspondingly, it is more likely to break, which leads to the scrapping of the product and increases the production cost

Embodiment Construction
[0046] The following examples can enable those skilled in the art to understand the present invention more comprehensively, but the present invention is not limited to the scope of the described examples.
[0047] Such as figure 1 The middle part of the fuse shown in the fittings includes successively connected fittings outer cylinder 1, fittings connecting cylinder 2, and fittings flat body 3, wherein the centerline of the fittings outer cylinder 1 and the centerline of fittings connecting cylinder 2 are perpendicular to each other, and the fittings The flat body 3 is arranged obliquely, and the inclination direction of the flat body 3 of the fittings is gradually inclined from the side where the flat body 3 of the fittings 3 is connected with the connecting cylinder 2 of the fittings to the direction away from the center line of the connecting cylinder 2 of the fittings.
[0048] In the middle fitting of the fuse, the height of the outer cylinder 1 of the fitting is h 1 , t...

The invention relates to a material-saving forging process for middle fittings of a fuse, which comprises the following steps of: firstly, taking a short and thick raw material, forming a slender material capable of forming two middle fittings in a blank rolling manner, flattening and bending the slender material, and forging the slender material into a blank; the method comprises the following steps of: forming a slender material into a hardware fitting connecting cylinder, a hardware fitting flat body and a hardware fitting outer cylinder semi-finished product, forging and forming to form two middle hardware fittings connected together, and finally cutting off to form the two required middle hardware fittings. The method has the advantages that two fuse middle fitting finished products can be processed from one metal raw material through cooperation of the procedures of blank rolling, flattening, bending, forging forming, cutting and the like, the utilization rate of the raw material is increased, material waste is reduced, and materials are relatively saved.
Description
technical field [0001] The invention relates to the field of processing metal fittings for fuses, in particular to a material-saving forging process for metal fittings in the middle of a fuse. Background technique [0002] Fuse refers to an electrical appliance that fuses the fuse with the heat generated by itself and disconnects the circuit when the current exceeds the specified value. The fuse is based on the fact that after the current exceeds the specified value for a period of time, the heat generated by itself melts the melt, thereby disconnecting the circuit; a current protector made by using this principle. Fuses are widely used in high and low voltage power distribution systems and control systems, as well as electrical equipment. As short circuit and overcurrent protectors, fuses are one of the most commonly used protection devices. [0003] When the fuse is installed, the middle part of the fuse is usually used to cooperate with the middle part of the fuse, such ...
