Problems solved by technology

Due to the uneven thickness of the casting clamp, there are a large number of casting defects such as shrinkage cavity and shrinkage porosity in the product
And in the production process, due to the small welding part of the wax mold, it is easy to drop parts, resulting in a low yield rate, and the product must be mechanically processed before it can be finally formed

Embodiment Construction

[0010] A forged clamp, two semicircular fixed rings 1 are hinged at one end, and the other ends of the two semicircular fixed rings 1 are fixed by fastening bolts 2 . One end of the two semicircular fixed rings 1 has a hole respectively, and the pin 3 passes through the hole, and the two semicircular fixed rings 1 rotate with the pin 3 as a rotating shaft. The fastening bolt 2 includes a screw rod and a nut. The screw rod passes through the other ends of the two semicircular fixed rings 1 and is fixed by the nuts. The fixed two semicircular fixed rings 1 are hollow circular.

[0011] The forged clamp of the present invention adopts high-quality profiles, is roasted at high temperature, is forged into a blank by a large air hammer, and sent to a fixed steel mold in a large friction press, forged and formed, and then sent to another press to remove flash. After completing the above work, qualified products are quenched and tempered with high-tech heat treatment technology, and ...

Abstract

The invention discloses a forging hoop. One end of one of two semicircular fixed rings is hinged to one end of the other semicircular fixed ring, and the other ends of the two semicircular fixed rings are fixed by a fastening bolt; one end of one semicircular fixed ring and one end of the other semicircular fixed ring are respectively provided with a hole; a pin penetrates through the holes; the two semicircular fixed rings rotate by adopting the pin as a rotary shaft. The fastening bolt comprises a screw rod and a nut, the screw rod penetrates through the other ends of the two semicircular fixed rings and is fixed by the nut, and the two semicircular fixed rings form a hollow circle after being fixed. The forging hoop disclosed by the invention has the advantages that the high-quality steel is adopted, a high-tech heat treatment technology is utilized, and one-time forging and forming is achieved; a product is flexible in disassembly and assembly, high in sealing degree and long in service life.

Description

technical field [0001] The invention relates to a forged clamp. Background technique [0002] At present, the pump truck elbow clamps used in the market are all made of castings. Due to the uneven thickness of the casting clamp, there are a large number of casting defects such as shrinkage cavity and shrinkage porosity in the product. And in the production process, because the welding part of the wax mold is small, it is easy to drop parts, resulting in a low yield rate, and the final product needs to be mechanically processed before it can be finally formed. Contents of the invention [0003] In order to solve the above-mentioned technical problems, the present invention provides a forged clamp, which is formed by forging high-quality steel, and used in combination, with flexible disassembly and assembly, high sealing degree and long service life. [0004] The above object of the present invention is achieved through such a technical solution: a forged clamp, two semic...
