Abstract
The utility model relates to a steel-plastic solid joint device of a thread protector, and relates to a protection kit of a steel pipe head, which is used for protecting threads on the end part of a petroleum bushing and different pipe fittings. The steel-plastic solid joint device comprises an upper machine head and a fixed platform which is arranged on the position corresponding to the bottom of the upper machine head, wherein the upper machine head is provided with a pressure wheel, a stamping rod which is connected with the pressure wheel, and a graver which is connected with the stamping rod through a connecting arm, and the graver is provided with a rubber mat. The fixed platform is provided with a positioning plate. The steel-plastic solid joint device has the beneficial effects that after being graved, inner steel is tightly combined with outer plastic between the graving combination points, so that the protector is integrally compact, and the phenomenon that the steel is separated from the plastic can be avoided.
Description
Technical field
The utility model relates to a kind of protection suite of steel pipe tube head, for the protection of petroleum casing pipe and all kinds of pipe end screw threads.
Background technology
Steel pipe, in transportation, very easily causes damage to pipe end, for tube head is protected,, at pipe end suit pipe cap, is generally also protector.The structure that in protector adopts, steel is moulded outward, is the overcoat that installs plastic material in the outside of steel bushing additional, increases the flexibility of protector entirety.Because steel is moulded thermal coefficient of expansion difference, in use procedure, likely occur steel mould between break-off, affect the use of protector.
Summary of the invention
The utility model provides threading protectors steel to mould firm joint device, and the steel bushing of protector inside and the outside plastic wrapper being provided with are connected together quarter, prevents mutual disengaging.
In order to achieve the above object, the technical scheme that the utility model is taked is:
A kind of threading protectors steel is moulded firm joint device; comprise the fixed platform that head and its bottom relative position are provided with, it is characterized in that: described upper head is provided with pinch roller, the punch rod being connected with pinch roller; be connected icking tool with punch rod by link arm, icking tool is provided with Rubber washer.
Above-described fixed platform is provided with location-plate.
The beneficial effects of the utility model are, through after carving and connecing, interior steel is moulded outward between the binding site connecing quarter and combined closely, and make protector entirety more solid, there will not be steel to mould break-off.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
In figure: 1. pinch roller; 2. go up head; 3. link arm; 4. Rubber washer; 5. icking tool; 6. location-plate; 7. punch rod; 8. fixed platform.
The specific embodiment
From accompanying drawing 1, the utility model comprises the fixed platform 8 that head 2 and its bottom relative position are provided with, and described upper head 2 is provided with pinch roller 1, and the punch rod 7 being connected with pinch roller 1 is connected icking tool 5 with punch rod 7 by link arm 3, and icking tool 5 is provided with Rubber washer 4.In above-described fixed platform 8, be provided with location-plate 6.
When use; protector opening is placed in fixed platform 8; and locate by location-plate 6; by the limit portion of icking tool 5 end alignment protector inner openings; start pinch roller 1, drive icking tool 5 to move down, on steel bushing, inscribe shrinkage pool; make down the shrinkage pool end of turning over enter in plastic wrapper, make the outer plastic wrapper being provided with of steel bushing and its be connected together quarter at shrinkage pool place simultaneously.By carving and connect 3-5 shrinkage pools on protector, can make the interior steel of protector mould outward and obtain good combination.
It should be noted that embodiment described in the utility model is only its optimal way, is only apparent change to belonging to technical solutions of the utility model, within all should belonging to protection domain of the present utility model.
