Abstract
The utility model relates to a metal part machining die, particularly to a bucket part necking machining die for machining bucket part workpieces. The bucket part necking machining die comprises an upper die and a lower die which are capable of moving up and down, wherein the lower die comprises a necking die which is located under the upper die; the necking die comprises a groove which is matched with outer contours of machined workpieces; a fixed block is arranged under the necking die; and an opening shaping block which is arranged inside the fixed block extends into the groove of the necking die from the bottom. According to the bucket part necking machining die, a cylindrical shell with a closed top and an opened bottom is pressed into the necking die to be deformed through the upper die and then deformation of an opening is limited through the opening shaping block, so that bucket part inverted cone workpieces with closed upper ends and opened lower ends are achieved.
Description
Technical field
The utility model relates to a kind of metalwork processing mold, especially a kind of bucket part reducing processing mold of processing barrel spare workpiece.
Background technology
In product processing, usually can meet the bucket part inverted cone surface workpiece of some upper end closeds, lower ending opening; as shown in Figure 1; the processing of this type of workpiece can not use conventional stamping die or other existing moulds to come moulding, and therefore being necessary to design a kind of new diel processes this type of workpiece.
Summary of the invention
The utility model provides a kind of bucket part reducing processing mold that can process the bucket part inverted cone surface workpiece of upper end closed, lower ending opening.
To achieve these goals, the utility model adopts following technical scheme:
It comprises a patrix movable up and down and a counterdie, described counterdie comprises the reducing mould that is positioned under the patrix, comprise a groove that adapts with the processing work outline in the reducing mould, described reducing mould below is provided with a fixed block, be provided with the opening dressing stick in the described fixed block, the opening dressing stick is stretched in the groove of reducing mould by the bottom.
Preferably, described fixed block below is provided with die shoe, connects strut on by elastic parts in the described die shoe, and last strut passes opening dressing stick and reducing mould, and last strut top is provided with a mounting plate.
Preferably, described patrix comprises a upper bolster, and the upper bolster below is provided with the briquetting that presses down workpiece.
Preferably, but described briquetting be located in the top board of an elastic telescopic, described top board is connected on the upper bolster by elastic parts.
Preferably, also be connected a guide post between described upper bolster and the top board.
Owing to adopted said structure, bucket part reducing processing mold of the present utility model is by the cylindrical shell of patrix with the top seal bottom opening, be pressed in the reducing mould and be out of shape, limit the deformation of opening part then by the opening dressing stick, thereby realize the bucket part inverted cone surface workpiece of upper end closed, lower ending opening.
Description of drawings
Fig. 1 is the cross section structure schematic diagram of barrel part workpiece;
Cross section structure schematic diagram when Fig. 2 is the die sinking of the utility model embodiment;
Cross section structure schematic diagram when Fig. 3 is the mold closing of the utility model embodiment.
Among the figure: reducing mould 1, groove 2, fixed block 3, opening dressing stick 4, die shoe 5, elastic parts 6, last strut 7, mounting plate 8, upper bolster 9, briquetting 10, top board 11, elastic parts 12, guide post 13.
The specific embodiment
Shown in Fig. 2-3, the bucket part reducing processing mold of present embodiment comprises a patrix movable up and down and a counterdie, described counterdie comprises the reducing mould 1 that is positioned under the patrix, comprise a groove 2 that adapts with the processing work outline in the reducing mould 1, described reducing mould 1 below is provided with fixed block 3, be provided with opening dressing stick 4 in the fixed block 3 under described, opening dressing stick 4 is stretched in the groove 2 of reducing mould 1 by the bottom.Add man-hour, patrix presses down, the cylindrical shell of top seal bottom opening is pressed in the groove 2 in the reducing mould 1, the lower openings of cylindrical shell is along with the process that presses down begins to shrink, because opening is when shrinking, sidewall is received extruding, after the sidewall extruding easily in opening part generation deformation, after the opening part generation deformation, can produce fold on the sidewall, so for fear of this type of situation, be provided with an opening dressing stick 4 in the fixed block 3 down thereupon, opening dressing stick and groove 2 interact, keep the cylindrical shell lower openings when being shaped as the less opening of bore, to keep circular, according to the characteristic of metal, smooth as long as opening part keeps, then sidewall also keeps level and smooth thereupon, thereby processes qualified bucket part workpiece.
Owing to receive in the process of extruding at sidewall, also the upper surface to the workpiece sealing applies certain pressure, may cause the flexural deformation of upper surface, in order to solve this type of problem, in the present embodiment, below described fixed block 3, be provided with die shoe 5, connect strut 7 on by elastic parts 6 in the described die shoe 5, last strut 7 passes opening dressing stick 4 and reducing mould 1, last strut 7 tops are provided with a mounting plate 8, and when patrix pressed down, patrix and mounting plate 8 withstood the upper surface of workpiece respectively from the above and below, make it not deform, also keep the carefully and neatly done level and smooth of sidewall thereupon.
In the concrete present embodiment, described patrix comprises a upper bolster 9, and upper bolster 9 belows are provided with the briquetting 10 that presses down workpiece; But described briquetting 10 is located in the top board 11 of an elastic telescopic, and described top board 11 is connected on the upper bolster 9 by elastic parts 12.The elementary step that patrix presses down, briquetting 10 shrinks in top board 11, along with patrix continue press down, it is out of service that top board 11 touches down fixed block 3 back, and briquetting 10 continues to press down under the promotion of upper bolster 9, this moment, elastic parts 12 was compressed.
In addition, in order to keep upper bolster and the top board accurate location in the process of pressing down, in the present embodiment, also be connected a guide post 13 between described upper bolster 9 and the top board 11.
The above only is preferred embodiment of the present utility model; be not so limit claim of the present utility model; every equivalent structure or equivalent flow process conversion that utilizes the utility model specification and accompanying drawing content to do; or directly or indirectly be used in other relevant technical fields, all in like manner be included in the scope of patent protection of the present utility model.
