Problems solved by technology

[0002] For example, threaded holes on the suspension surface of engine parts, oil drain holes, and threaded holes on other products that are subject to greater stress and are frequently assembled and disassembled. Threaded holes must withstand frequent installation and disassembly in maintenance and other links. Because the threaded holes processed directly on non-ferrous alloy products, their thread strength cannot withstand the high pulling force and frequent installation and disassembly as mentioned above, which can easily cause threaded threads. The entire product is scrapped due to strain and wear

Embodiment Construction

[0009] One end of the screw body 5 is provided with an external thread that cooperates with the internal thread of the self-tapping threaded bush, the middle section of the rod body is provided with a table that cooperates with the limit block 3, and the other end is provided with a square hole that cooperates with a standard pneumatic or electric tool wrench. The limit block 3 is fixed on the table top of the rod body in the middle section of the screw body 5 through the pin shaft 4 . The front end 7 of the self-tapping threaded bush 2 is designed in the form of a taper, which is convenient for playing a guiding role when the self-tapping threaded bush enters the product. The front end 7 of the self-tapping threaded bush 2 is designed in the form of two symmetrical openings 6. The design of the openings 6 is mainly to cooperate with the base of the aluminum alloy product 1. The self-tapping thread bushing 2 is tapped into the interior of the aluminum alloy product 1 . Accord...

Abstract

The invention discloses a self-tapping thread bushing tool, and belongs to the technical field of control equipment in the casting production process. The self-tapping thread bushing tool mainly solves the problems that according to a traditional cooling method, different cooling speeds required by parts of a casting in a die cavity cannot be accurately met, and hole shrinkage, shrinkage porosity, cracks and other casting defects are extremely prone to happening to key parts of the casting due to too high or too low cooling speed. Different cooling speeds for multiple positions of the same metal die can be achieved at will through a set of device, and the self-tapping thread bushing tool has the beneficial effects of being fast in installation, capable of saving labor, flexible and reliable in work and is mainly used for cooling of various metal dies.

Description

technical field [0001] The invention relates to the technical field of quick-installation self-tapping thread bushings. Background technique [0002] For example, threaded holes on the suspension surface of engine parts, oil drain holes, and threaded holes on other products that are subject to greater stress and are frequently assembled and disassembled. Threaded holes must withstand frequent installation and disassembly in maintenance and other links. Because the threaded holes processed directly on non-ferrous alloy products, their thread strength cannot withstand the high pulling force and frequent installation and disassembly as mentioned above, which can easily cause threaded threads. Strain, wear and tear will cause the entire product to be scrapped. Contents of the invention [0003] The object of the present invention is to provide a self-tapping thread bushing tool for the above-mentioned disadvantages. [0004] The technical solution of the present invention is...
