Abstract
The utility model relates to the field of machinery and provides a fixed part comprising a hollow cylinder, wherein the inner wall of the hollow cylinder is provided with at least two circles of horizontally-arranged boss stations, the boss stations are respectively provided with two uniformly-distributed bosses protruding towards the center of the cylinder, and the hollow cylinder is formed through cold stamping; the fixed part is made of a cold-rolled iron plate and is low in production cost, not easy to deform and long in service life; and the fixed part is machined by using a cold-stamping method, few in machining programs, high in stamping speed up to 2-3/s, not easy to scrap, high in machining efficiency and incapable of causing material waste.
Description
Technical field
The utility model relates to mechanical field, relates in particular to a kind of fixed block.
Background technique
Fixed block is a kind of mechanical parts that are used for fixing a base part, plays axially locating, the effect of anti-attrition damping; Fixed block commonly used is to become the hollow cylinder shown in accompanying drawing 3 with solid copper pin with machined into, and the inwall of cylinder has all boss, and the parts that will fix during use stick into from the two ends of hollow cylinder fixed block, with said fixed block chucking; Such copper fixed block cost of production is high, and copper product hardness is less, and is yielding; And work flow is many, and technology is more loaded down with trivial details, and it is low to make efficient, also gets worse the copper post easily, and scrappage is high, waste material.
The model utility content
The purpose of the utility model be to provide a kind of processing technology easier, make higher, the lower-cost fixed block of efficient, comprise a hollow cylinder;
The inwall of said hollow cylinder has the boss position of at least two all horizontal arrangement, has at least two on each boss position respectively and evenly distributes and protruding boss to cylindrical center;
Said hollow cylinder is cold stamping shaped hollow cylinder;
Said hollow cylinder is the hollow cylinder of processing with cold-reduced sheet;
The utility model beneficial effect compared with prior art is:
(1) said fixed block adopts cold rolling iron plate to make, and cost of production is low, and is not yielding, long service life;
(2) processing technology of said fixed block is selected the cold-stamped method for use, and procedure is few, and processing is fast, and one second can punching press 2-3, and be difficult for scrapping, and work efficiency is high, can not cause the waste of material.
Description of drawings
Accompanying drawing 1 is the plan view of the said a kind of fixed block of expression the utility model;
Accompanying drawing 2 is that the said a kind of fixed block A-A of expression the utility model is to sectional structure chart;
Accompanying drawing 3 is structural drawing of existing technology copper post fixed block.
Embodiment
Shown in accompanying drawing, Fig. 1 is the plan view of the said a kind of fixed block of the utility model;
Fig. 2 be the A-A of fixed block shown in Figure 1 to sectional structure chart, wherein, the 21st, protruding boss to cylindrical center;
Fig. 3 is a structural drawing of representing copper post fixed block commonly used in the existing technology, and the inwall of hollow cylinder has all boss;
The described fixed block of the utility model; Comprise a hollow cylinder; The inwall of said hollow cylinder has at least two all boss positions, has at least two on each boss position respectively and evenly distributes and protruding boss to cylindrical center, and said hollow cylinder is cold stamping shaped hollow cylinder;
The specific operation step is: stamping press is opened in (1), and the square cold rolling iron plate that a thickness is even, two ends length exceeds 2-4 centimetre of said hollow cylinder circumferential length is respectively sent into said stamping press through the material feeding mouth of stamping press; (2) said stamping press stamps out said boss on the surface of said sheet metal; (3) said stamping press strikes out a plurality of biscuit metal plates with the sheet metal of step (2) gained; And the both ends of the surface of said biscuit metal plate are gone out can intermeshing breach; Said biscuit metal plate two side portions still is connected on the block of metal plate, does not break away from the block of metal plate fully; (4) said stamping press strikes out the quadrant post earlier with the sheet metal of step (3) gained, strikes out semicolumn again, strikes out whole cylinder at last, and the cylinder seam portion is that said sheet metal two ends are meshing with each other and form; (5) said stamping press is washed the cylinder of step (4) gained open with the part that the block of metal plate is connected, and sees stamping press off, obtains fixed block according to the invention.
Drawn by above embodiment, the utility model beneficial effect compared with prior art is:
(1) said fixed block adopts cold rolling iron plate to make, and cost of production is low, and is not yielding, long service life;
(2) processing technology of said fixed block is selected the cold-stamped method for use, and procedure is few, and processing is fast, and one second can punching press 2-3, and be difficult for scrapping, and work efficiency is high, can not cause the waste of material.
More than technological scheme that the utility model embodiment is provided carried out detailed introduction; Used concrete example among this paper the utility model embodiment's principle and mode of execution are set forth, above embodiment's explanation only is applicable to the principle that helps to understand the utility model embodiment; Simultaneously, for one of ordinary skill in the art, according to the utility model embodiment, the part that on embodiment and application area, all can change, in sum, this description should not be construed as the restriction to the utility model.
Claims (3)
