Abstract

The utility model discloses a stripping chuck, and relates to auxiliary devices for machining, in particular to a stripper device used in molding process of a drilling bit. The stripping chuck comprises an inner expansion head (5), an outer expansion body (6), a tensioning nut (7), a tensioning screw (8) and a hanging ring (9). The outer surface of the lower portion of the outer expansion body (6) is a cylindrical body which is matched with a mold core inner hole. A cone-shaped hole which is communicated to the lower end face is formed in the outer expansion body (6). The inner expansion head (5) is arranged in the outer expansion body (6). The outer surface of the inner expansion head (5) is a cone-shaped surface which is matched with the cone-shaped hole of the outer expansion body (6). The tensioning screw (8) penetrates through the lower end of the outer expansion body (6) from the top of the outer expansion body (6) to be connected with the inner expansion head (5). The tensioning nut (7) is arranged above the outer expansion body (6) and is in spiral fit with the tensioning screw (8), and the hanging ring (9) is connected at the top end of the tensioning screw (8). The stripping chuck is used by being matched with a stripper machine, is used for clamping machined workpieces, and can improve labor intensity of workers, improve working efficiency and improve stripping accuracy in the molding process of the drilling bit for oil production.

Description

Demoulding chuck
Technical field
The utility model relates to the machining servicing unit, is specifically related to the stripper apparatus used in oily drilling bit pattern making procedure.
Background technology
Ingot stripper is while producing petroleum drilling bit, the special equipment in pattern making procedure, the excessive mould of mould and rubber separated.Specially for improving labor strength, increasing work efficiency, improve the custom-designed special equipment of demoulding precision.For coordinating ingot stripper, be necessary to arrange a kind of rational in infrastructure, easy to use, for clamping the demoulding chuck of processed workpiece.
Summary of the invention
The utility model provides demoulding chuck, and the utility model and ingot stripper support the use, and for clamping processed workpiece, improves labor strength in the pattern making procedure of producing petroleum drilling bit, increases work efficiency, improves demoulding precision.
For addressing the above problem, the utility model adopts following technical scheme: demoulding chuck comprises interior expansion-head 5, outer expander 6, tensioner nut 7, tensioner screw rod 8 and suspension ring 9; The outer surface of outer expander 6 bottoms is the cylindrical body that coordinate with core rod 3 endoporus, in outer expander 6, the bellmouth that penetrates into lower surface is arranged, and interior expansion-head 5 is arranged in outer expander 6, and interior expansion-head 5 outer surfaces are the taper surfaces that coordinate with outer expander 6 bellmouths; Tensioner screw rod 8 from expander 6 tops with interior expansion-head 5, be connected through lower end; Tensioner nut 7 is arranged at outer expander 6 tops, and tensioner nut 7 coordinates with tensioner screw rod 8 spirals, and tensioner screw rod 8 tops are connected with suspension ring 9.
Demoulding chuck of the present utility model is one of main executing agency on ingot stripper, and its advantage is: 1, demoulding chuck is comprised of interior expansion-head, outer expander, tensioner nut, tensioner screw rod, suspension ring, simple in structure.2, produce knockout press (frictional force) by changing conical surface angles different between interior expansion-head, outer expander; By changing tensioner screw spiral lift angle, make clamping force adjustable.3, simple to operate.4, adhesion is strong.5, good looking appearance, compact conformation.6, low, the high efficiency of labor strength, demoulding precision are high.
The accompanying drawing explanation
Fig. 1 is the utility model schematic diagram;
Fig. 2 is the utility model structural representation.
Symbol description in figure: external mold 1, workpiece 2, core rod 3, demoulding chuck 4, interior expansion-head 5, outer expander 6, tensioner nut 7, tensioner screw rod 8, suspension ring 9.
The specific embodiment
below with best embodiment, the utility model is described in detail .
As shown in Figure 1-2, demoulding chuck, comprise interior expansion-head 5, outer expander 6, tensioner nut 7, tensioner screw rod 8 and suspension ring 9; The outer surface of outer expander 6 bottoms is the cylindrical body that coordinate with core rod 3 endoporus, in outer expander 6, the bellmouth that penetrates into lower surface is arranged, and interior expansion-head 5 is arranged in outer expander 6, and interior expansion-head 5 outer surfaces are the taper surfaces that coordinate with outer expander 6 bellmouths; Tensioner screw rod 8 from expander 6 tops with interior expansion-head 5, be connected through lower end; Tensioner nut 7 is arranged at outer expander 6 tops, and tensioner nut 7 coordinates with tensioner screw rod 8 spirals, and tensioner screw rod 8 tops are connected with suspension ring 9.
The utility model operation principle: demoulding operation principle (see figure 1), workpiece after casting is completed (the excessive mould of rubber) is placed on the ingot stripper platform together with mould, demoulding oil jar stretches out, and demoulding chuck inserts the core rod endoporus, screws the tensioner nut with spanner core rod is tightened; Mould external mold clamp mechanism action simultaneously tightens mold shell; Demoulding oil jar is retracted, and the excessive mould of rubber is pulled out (mould separates with workpiece); Demoulding chuck has unclamped demoulding work.
The task of demoulding chuck is external mold, workpiece, the core rod chucking will be cast as one, and mould emptier is extracted core rod out by demoulding chuck.Core rod is steel material, and core rod and demoulding chuck junction are a face of cylinder, and correlation is shown in Fig. 1.After demoulding chuck is in place, operation principle is shown in Fig. 1.
Tensioner nut active force makes to produce displacement between interior expansion-head and outer expander by the tensioner screw rod, because making outer expander, the effect (between interior expansion-head and outer expander, being designed to cone match) of the conical surface produces radial displacement, make between outer expander and core rod and coordinate for gapless, and there is certain radial tightening power (normal pressure) to produce frictional force, demoulding oil jar is retracted and is pulled suspension ring to rely on frictional force to pull out core rod, and work completes.
Finally it should be noted that: obviously, above-described embodiment is only for the utility model example clearly is described, and is not the restriction to embodiment.For those of ordinary skill in the field, can also make other changes in different forms on the basis of the above description.Here exhaustive without also giving all embodiments.And the apparent variation of being amplified out thus or change are still among protection domain of the present utility model.
