Abstract
The utility model puts forwards a mold for valve blank processing, wherein the mold is cylindrical, an inner cavity is stair-shaped, diameter of the left end of the inner cavity is bigger than the diameter of the right end, an opening is disposed on one side face of the mold, the opening section has an U-shaped structure, the rest section has a rectangular structure and the sections are mutually communicated. In comparison with an existing spring collet, the mold for the valve blank processing in the utility model is simple in structure, easy in processing and low in production cost; has the rational structure and is more durable than the spring collet; leaves out the procedure in which a blank shall be selected in advance, increases working efficiency and reduces production cost; and has reliable clamping effect and avoids position offset and breaking of the valve bland during processing in order to greatly increase processing pass percent of the valve blank.
Description
Technical field
The utility model relates to a kind of frock clamp, particularly relates to a kind of mold for valve body blank forming.
Background technology
At present, while using simple cnc lathe processing valve body blank, the collet clamping valve body blanks that adopt more, due to the restriction of collet structure, can make clamping insecure because of valve body blank surface irregularity, cause the phenomenon that adds the skew of valve body blank in man-hour position, fracture, thereby cause valve body blank forming scrappage higher; Due to valve body blank surface irregularity, be difficult for valve body blank quick-clamping to put in place, cause before clamping, conventionally must screen in advance the valve body blank of regular shape, carry out again manufacturing procedure, so just increased operative employee's non-cutting time, reduced operating efficiency, and the collet process-cycle is longer, cost is also higher.In sum, now use collet clamping valve blank, exist clamping not firm, length consuming time, inefficiency, scrappage is high, the large and high deficiency of processing cost of labour intensity.
Summary of the invention
The purpose of this utility model is to provide a kind of mold for valve body blank forming, not firm to solve the clamping blank that existing collet exists, length consuming time, and inefficiency, scrappage is high, the large and high deficiency of processing cost of labour intensity.
The purpose of this utility model can reach by following technical measures, it is this mold for valve body blank forming, it is characterized in that: described mold is cylindrical, inner chamber is stepped, inner chamber left end diameter is greater than right-hand member diameter, and mold side is provided with an opening, and one section of described opening is U-shaped structure, residue section is rectangle structure, and mutually connects.
Further, the utility model is for the mold of valve body blank forming, and the U-shaped extended distance of its mold side is that 18～20 millimeters, rectangle structure extended distance are 5～8 millimeters.
Further, the utility model is for the mold of valve body blank forming, large 0.5～1 millimeter than valve body blank outside diameter of the diameter of its inner chamber.
The utility model is used for the mold of valve body blank forming compared with existing collet, and due to simple in structure, handling ease and production cost are low; Due to rational in infrastructure, more durable than collet; Due to the diameter of mold inner chamber than valve body blank outside diameter large 0.5～1 millimeter, the setting of U-shaped opening in addition, even valve body profile rule not, also can be packed easily into mold inner chamber, save the program that need select in advance blank, improved operating efficiency, reduced production cost; Because positioner structure is reasonable, make its clamping reliable, avoid adding the phenomenon of the skew of valve body blank in man-hour position, fracture, thereby greatly improved valve body blank forming qualification rate.
Accompanying drawing explanation
Fig. 1 is the structural representation of existing collet;
Fig. 2 is the structural representation of the utility model for the mold of valve body blank forming.
Below in conjunction with the drawings and specific embodiments, the utility model is further described for the mold of valve body blank forming.
The specific embodiment
Fig. 1 is the structural representation of existing collet, wherein, 1 is existing collet, as shown in Figure 1, in the time using existing collet clamping valve body blank, due to the restriction of collet structural principle, because of valve body blank surface irregularity, clamping is insecure in meeting, causes to add the skew of valve body blank in man-hour position, cause valve body blank forming scrappage higher, and need to filter out surface comparatively regular valve body blank process, much time power, increase cost, lower efficiency.
Referring to Fig. 2,2 is mold; A kind of mold for valve body blank forming of the utility model, it is characterized in that: described mold 2 is cylindrical, inner chamber is stepped, inner chamber left end diameter is greater than right-hand member diameter, mold 2 sides are provided with an opening, one section of described opening is U-shaped structure, and residue section be rectangle structure, and perforation mutually.
The U-shaped extended distance of described mold 2 is that 18～20 millimeters, square structure extended distance are 5～8 millimeters, in the present embodiment, U-shaped structural openings distance is that 19 millimeters, rectangle structure extended distance are 6 millimeters, and the effect that opening is set is to increase the elasticity of mold and is valve body blank protrusion of surface part headspace; Large 0.5～1 millimeter than valve body blank outside diameter of the diameter of mold 2 cylindrical cavities, can be 0.5 millimeter, and its effect is to be convenient to valve body blank to put in mold.
In the time that reality is used, the just U-shaped opening to the mold for valve body blank forming of valve body blank rat part, make in the U-shaped opening of valve body blank rat part in mold, then use scroll chuck to clamp the mold 2 that valve body blank is housed, the claw of scroll chuck is directly clipped in mold 2 outer round surface, the stressed compression of mold 2 clamps valve body blank, thereby valve body blank clamping is put in place.Due to the utility model for the mold 2 of valve body blank forming for thering is flexible tube-in-tube structure, make clamping valve body blank easier and firm.
The utility model is used for the mold 2 of valve body blank forming compared with 1 of existing spring clip, and due to simple in structure, handling ease and production cost are low; Due to rational in infrastructure, more durable than collet 1; Due to the diameter of mold 2 inner chambers than valve body blank outside diameter large 0.5～1 millimeter, the setting of U-shaped opening in addition, even valve body profile rule not, also can be packed easily into mold 2 inner chambers, save the program that need select in advance blank, improved operating efficiency, reduced production cost; Because mold 2 is rational in infrastructure, make its clamping reliable, avoid adding the phenomenon of the skew of valve body blank in man-hour position, fracture, thereby greatly improved valve body blank forming qualification rate.
