Cable clamp production technology

Abstract

The invention relates to a cable clamp production technology which comprises the following steps: S1, preparing molten metal: smelting 20-30 parts by mass of steel blocks, 80-90 parts by mass of aluminium block and 5-10 parts by mass of titanium block in a smelting furnace to prepare the molten metal; S2, carrying out die casting: carrying out press-shoot on the molten metal prepared in S1 into adedicated vacuum die-casting die to manufacture a clamp casting, wherein the temperature of the die-casting die is 350-400 DEG C, the die-casting pressure is 80-90 MPa, and the vacuum degree in the vacuum die-casting die is 50-60 KPa; S3, removing a riser and runner; and S4, shot blasting: placing the manufactured clamp casting in a shot blasting machine for shot blasting, so that the tensile strength of the manufactured clamp casting is 210-230 MPa, and the elongation is 7.56-7.95%. The cable clamp production technology has the following advantages: the tensile strength and the elongation ofthe manufactured cable clamp is ensured to be 210-230 MPa and 7.56-7.95% separately, the cable clamp is ensured to generate better thermal impact damage resistance and have higher thermal conductivity.

Description

Technical field: [0001] The invention relates to the field of cable clamp processing, in particular to a production process of the cable clamp. Background technique: [0002] The cable clamp is a special fixture used to fix the cable after laying and installing the cable, so that the cable occupies the correct position, and prevents the cable from moving due to external force or self-weight. A new, beautiful and practical cable fixing product. [0003] Most of the cable clamps are made of aluminum, which has poor stability against high temperature. During the process of clamping the cable, a magnetic field will be generated when the current flows through the cable, resulting in the formation of a magnetic field closed loop between the clamps, which will increase the temperature of the cable, especially when the cable passes through the cable. When the current is high, the temperature rises rapidly, and the high temperature causes impact damage inside the cable clamp, causin...

Problems solved by technology

[0005] However, during vacuum die-casting of existing vacuum die-casting molds, the molten metal flows to the cavity through the pressure head, and the vacuum tube located on the other side of the cavity is evacuated by a vacuum pump, thereby quickly removing part of the gas in the cavity. However, when the molten metal When the liquid metal flows into the cavity, the vacuum pump needs to be stopped, otherwise the molten metal will block the vacuum pump with the gas flowing to the vacuum tube and vacuum pump, but the vacuum pump will be turned off when the molten metal starts to flow into the cavity, then the gas in the cavity cannot be completely removed, and the vacuum pump cannot be reached. Therefore, the current vacuum die-casting technology is still unable to ensure the high vacuum of the cavity and avoid the blockage of the vacuum pump by the molten metal, and it is impossible to ensure that the cable clamp can produce better thermal shock damage resistance. , but also have a high thermal conductivity
