Abstract
The utility model relates to a frock for making press upper portion instrument, characterized in that: ellipse cylinder including integrated into one piece, the system had the recess that is used for with the protruding key of work piece dress card on ellipse cylinder corresponded both sides plane axial, recess and ellipse cylinder both sides plane, both ends face to in and the symmetry be 0.01, make the bulge as an organic whole rather than the company respectively at the both ends of ellipse cylinder, the system has the fabrication hole of the work piece assembly of being convenient for on the ellipse cylinder. The advantage is: the adoption can effectually solve work piece deformation in the processing, can't guarantee into the unanimous difficult problem of packet size through the frock cooperation lathe and the grinding machine use tonnage machine upper portion instrument of optimal design, has increased substantially the machining precision, has broken through the bottleneck of whole processing, this tooling design is converted products in pairs, and then has improved machining efficiency.
Description
Technical field
The utility model belongs to field of machining, particularly relates to a kind of frock for making forcing press upper tool.
Background technology
Forcing press is mainly used in metallurgic product manufacturing, wherein, upper tool is the parts of comparatively core on forcing press, is that forcing press directly contacts the important Parts (as shown in Figure 4) of work with workpiece, every 30 upper tools are one group, and the push type broach being assemblied in forcing press works simultaneously.Because upper tool material is high carbon and chromium cold work die steel, have high quenching degree and hardenability, this part requirement integral quenching, hardness is higher, and distortion is comparatively large, and mechanical performance is restive; And machining accuracy is high, easily produce machining deformation in the position stress release of locating slot.Therefore requiring often to organize upper tool critical size (110, R155,80 ± 0.05) must be consistent, ensures that it possesses interchangeability, otherwise directly affects the quality of converted products.At present, upper tool adopts the mode (especially R155 size) of single-piece work to be the interchangeability being difficult to ensure machining accuracy and workpiece.
Summary of the invention
The utility model provides a kind of and efficiently solves machining deformation, improve machining accuracy and working (machining) efficiency and can ensure the frock for making forcing press upper tool of workpiece consistent size in groups for solving in known technology the technical problem that exists.
The technical scheme that the utility model is taked for the technical problem existed in solution known technology is:
For making the frock of forcing press upper tool, it is characterized in that: comprise integrated oval column, described oval column corresponding both sides plane axis is upwards shaped with the groove for being installed with the convex key of workpiece, described groove and oval column two side plane, both ends of the surface in and symmetry be 0.01, be shaped with the protuberance be connected as a single entity with it at the both ends of oval column respectively, described oval column be shaped with the fabrication hole being convenient to workpiece assembling.
The utility model can also adopt following technical scheme:
The arc radius of described oval column and the ratio of Workpiece's Arc Radius are 1:1.25.
The unthreaded hole of fixation workpiece is shaped with in the groove of described oval column.
The advantage that the utility model has and good effect are: because the utility model adopts technique scheme, the frock through optimal design is adopted to coordinate lathe and grinding machine to use tonnage machine upper tool effectively can solve workpiece deformation in processing, a difficult problem for consistent size in groups cannot be ensured, increase substantially machining accuracy, breach the bottleneck of overall processing; This Fixture Design is paired converted products, and then improves working (machining) efficiency.

Detailed description of the invention
For summary of the invention of the present utility model, Characteristic can be understood further, hereby exemplify following examples, and coordinate accompanying drawing to be described in detail as follows:
Referring to Fig. 1-Fig. 3, for making the frock of forcing press upper tool, comprising integrated oval column 1, the groove 3 be axially shaped with for being installed with the convex key of workpiece of corresponding two side planes 2 of described oval column.Described groove and oval column two side plane, both ends of the surface in and symmetry be 0.01, be shaped with the protuberance 4 be connected as a single entity with it at the both ends of oval column respectively, described oval column be shaped with the fabrication hole 5 being convenient to workpiece assembling.
In the present embodiment, the arc radius of described oval column and the ratio of Workpiece's Arc Radius are 1:1.25, and the large cylindrical of described oval column is designed to be less than Φ 310 (i.e. workpiece 2 times of arc size R155), to ensure that R155 adds man-hour without interference; Little outer circles ensures 0.015, provides centering benchmark, ensures machining accuracy.
In the present embodiment, in the groove of described oval column, be shaped with the unthreaded hole 6 of multiple fixation workpiece 7.
Operation principle of the present utility model is:
Refer to Fig. 4 and Fig. 5, a workpiece is inserted the groove fit location of this frock one end face by the convex key of its upper surface, again the convex key of another workpiece upper surface is inserted the groove fit location of this frock other end, by 2 M12 screwed holes, two workpiece are assemblied in this frock simultaneously, the gap value of strict control faying face, paired processing work.
Rough mill workpiece configurations, R155 external arc, convex key upper and lower end face/left and right facade and 110 size both ends of the surface allowances, fine finishining after quenching, the thick fine finishining of all the other profiles survives.(0.01mm does not enter) is detected with clearance gauge; Double Tops clamping, little this frock of cylindrical centering, overall rough turn, quenching rear fine grinding excircle of workpiece arc R155.
The arc surface 7-1 of finishing workpiece again, refines convex key up/down end face, left/right facade survives, and ensures 80 ± 0.05 sizes.
The embodiment that the utility model accompanying drawing describes is exemplary, only for explaining the utility model, and can not be interpreted as restriction of the present utility model.
