Casting parts method and forging press for forging casting part with side opening or pleural furrow, and adjustable wrench

Abstract

The invention relates to a method for forging a casting with a side hole or a side groove and a forging press used in the method and provides a monkey wrench machined by the method. The invention overcomes the drawbacks that the prior method for forming parts with side holes or side grooves has a plurality of procedures, high cost and long period, and introduces forging into a process for forming parts with a side hole or a side groove. The method has less working procedures, reduces labor and materials, has low manufacture cost, and shortens the production period. Parts formed by the method have high density, high toughness and mechanical strength, small coefficient of deformation, high surface finish quality and accurate size. In addition, the money wrench machined by the method has a reasonable load bearing structure, eliminates a shake gap between a movable jaw and a fixed jaw to prevent the movable jaw shakes during the operation of the wrench, improves the accuracy of clamping, prevents reduction in clamping torque force and deformation of the fixed jaw, prolongs the service and achieves low manufacture cost.

Description

technical field [0001] The invention relates to a casting and forging method, in particular to a casting forging method with side holes or side grooves, a forging press used in the method and an adjustable wrench formed according to the method. Background technique [0002] At present, commonly used parts with side holes or side grooves, such as adjustable wrenches, pipe wrench, etc., are usually produced by machining methods, that is, complex production processes such as drilling, milling, and slots are required. It usually requires the simultaneous cooperation of multiple workers and multiple machines to process and form, which has high production costs and long production cycles. With the development of casting technology, casting processing is more and more used in the manufacture of such parts. As we all know, the inside of the casting is easy to produce pores, and the surface is prone to cracks. At the same time, the internal structure of the casting is loose. Therefo...

Problems solved by technology

[0005] The purpose of the present invention overcomes the defects of the existing parts forming method with side holes or side grooves, which have many procedures, high cost and long cycle, and introduces forging into the forming process of this type of parts. The method has fewer procedures and reduces The required manpower and material resources are reduced, the manufacturing cost is low, and the production cycle is shortened; the internal structure of the parts made by the process method of the present invention is dense, the density is high, the toughness and mechanical strength are good, the deformation coefficient is small, and the surface finish is smooth. High and accurate in size; when processing adjustable wrench by this method, the cross-sectional shape of the sliding groove of existing adjustable wrench can be improved, so that the force of the adjustable wrench is reasonable, and the shaking gap between the movable jaw and the fixed jaw can be eliminated , prevent the shaking of the movable jaw when the wrench is pulled, improve the clamping accuracy, will not cause the reduction of the clamping torque, and prevent the deformation of the fixed jaw, prolong the service life of the movable wrench, and the manufacturing cost is low
