Method for processing plumb bob

Abstract

The invention discloses a method for processing a plumb bob. The method includes 1) processing a blank into the thick end portion; 2) placing the thick end portion at a corresponding position in a plumb bob mold, then directly placing a material for manufacturing the apex portion of the plumb bob into the mold, forming the material for manufacturing the apex portion of the plumb bob into the apex portion by the aid of forming process of the mold, combining the apex portion with the thick end portion during forming, and inlaying a hinge pin on the end surface of a thin end of the thick end portion into the apex portion; and 3) processing an annular groove along a combined circumference of the apex portion and the thick end portion, tightly sleeving a rubber ring in the annular groove and completing processing of the plumb bob. By the aid of the method, stability of the structure of the plumb bob can be effectively guaranteed, components of the plumb bob cannot drop or be separated from each other, and safety is ensured. In addition, the integral plumb bob does not need to be completely made of materials which guarantee the hardness of an apex end, accordingly, high-quality material consumption is decreased, and cost is reduced.

Description

technical field [0001] The invention relates to a jackhammer for construction, in particular to a processing method of the jackhammer. Background technique [0002] The jackhammer is the most common auxiliary tool on the construction site. It can help the construction workers to keep the wall vertical to the horizontal plane. The shape of the hanging hammer is generally a standard spindle shape. Because most of the pendant hammers are of solid structure, there are many defects in the processing process: 1. If wrought iron and other blanks are used for processing, it is very difficult to process the blank into a spindle body with a tip at one end and a thicker end at the other end , especially the larger the diameter of the butt end, the more difficult it is to process, and it may even be unsuccessful at one time. At the same time, this processing method will also cause a lot of waste of materials, which will increase the cost; 2. If the integrated processing is carried out...

Because most of the pendant hammers are of solid structure, there are many defects in the processing process: 1. If wrought iron and other blanks are used for processing, it is very difficult to process the blank into a spindle body with a tip at one end and a thicker end at the other end , especially the larger the diameter of the butt end, the more difficult it is to process, and it may even be unsuccessful at one time

However, such a pendant hammer is easy to loosen at the connection during use, resulting in deviations during use, which affects the construction, and even the tip of the cone falls, which poses a serious safety hazard; at the same time, the existing split structure There is also the problem of poor commerciality at the junction of the cone tip and the butt end (the stitching line at the junction is easy to see with the naked eye), which affects sales
