Description
Technical Field
The utility model relates to the field of dies, in particular to novel tight mould of oil pipe tip shaping clamp.
Background
The mode that steps up that present tip forming die adopted is hard steps up, carries out interference fit through anchor clamps working surface and pipeline surface and realizes stepping up, and novel material PP manages surface one deck and is the PP material, and this material hardness is on the low side, can't adopt early hard mode that steps up to process: the current applicable laws include scheme one: increase the magnitude of interference to increase the packing force to the PP layer, prevent to press from both sides tight the slip, scheme two: thereby change the material of anchor clamps working face and adjust coefficient of friction, prevent to press from both sides tight the skidding, to scheme one: because the surface material of the PP pipe is polypropylene, the PP pipe has certain elasticity, the actual effect obtained by increasing the interference is not obvious, and the large interference can cause serious clamp marks on the surface of the pipe. Aiming at the scheme II: a plurality of materials are selected for testing, and the result shows that a proper material cannot be found in a short time, and even if a proper material is found, the service cycle of the material is short, so that the existing production requirement cannot be met.
Therefore, it is necessary to invent a novel clamping mold for forming the end of the oil pipe to solve the above problems.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a novel tight mould of oil pipe tip shaping clamp to solve the problem that proposes among the above-mentioned background art.
In order to achieve the above object, the utility model provides a following technical scheme: the utility model provides a novel tight mould of oil pipe tip shaping clamp, includes first tight piece of clamp, first tight piece one side of clamp is provided with the tight piece of activity clamp, the tight piece one side of activity clamp is provided with the spring gasket, spring gasket one side is provided with the tight piece of second clamp, the tight piece inside fixed pin that is provided with of second clamp, be provided with the joint between the tight piece of first clamp and the tight piece of second clamp, first tight piece one end of clamp is provided with the pier nose, first tight piece opposite side of clamp is provided with the PC pipe.
Preferably, a first groove is formed in one side surface of the first clamping block.
Preferably, a second groove is formed in one side of the movable clamping block.
The utility model discloses a technological effect and advantage:
the utility model discloses a be provided with the tight piece of first clamp, the tight piece of activity clamp, spring shim, the tight piece of second clamp, fixed pin, joint, pier nose, first recess, second recess, the effectual clamp force that improves the mould has solved the processing difficulty that arouses because of the PP external diameter tolerance is great, by a wide margin improvement the fashioned qualification rate of PP pipe end, avoid mechanical injury, realize safety in production.
Drawings
Fig. 1 is a schematic view of the overall structure of the present invention.
Fig. 2 is an exploded view of the present invention.
In the figure: 1 first clamp tight piece, 2 activity clamp tight piece, 3 spring gaskets, 4 second clamp tight pieces, 5 fixed pins, 6 joints, 7 pier nose, 8PC pipes, 9 first recesses, 10 second recesses.
Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
The utility model provides a novel tight mould of oil pipe tip shaping clamp as shown in fig. 1-2, including first tight piece 1 of clamp, its characterized in that: first tight piece 1 one side of clamp is provided with the activity and presss from both sides tight piece 2, the activity presss from both sides tight piece 2 one side and is provided with spring gasket 3, spring gasket 3 one side is provided with the tight piece 4 of second clamp, the tight piece 4 inside of second clamp is provided with fixed pin 5, be provided with between the tight piece 4 of first tight piece 1 of clamp and the tight piece 4 of second clamp and connect 6, 1 one end of first tight piece of clamp is provided with pier nose 7, 1 opposite side of first tight piece of clamp is provided with PC pipe 8.
Further, in the above technical solution, a first groove 9 is formed on a surface of one side of the first clamping block 1;
further, in the above technical solution, a second groove 10 is provided at one side of the movable clamping block 2.
This practical theory of operation:
referring to the description attached drawing 1-2, use the utility model discloses the time, PC pipe 8 wears to connect 6, puts into first clamp tight piece 1, activity and presss from both sides in tight piece 2 first recess 9, the second recess 10, puts into the front chamber to connect 6, opens the lathe switch, and 3 numbers of adjusting spring gasket, the removal activity presss from both sides tight piece 2 and first clamp tight piece 1 and presss from both sides tight PC pipe 8, and the second presss from both sides tight piece 4 fixed at last. The pier head 7 advances to extrude the PC pipe 8 forwards, and the end part is molded into a fixed shape. The outer layer of the PC pipe 8 is wrapped by polypropylene, the hardness of the surface layer is small, clamping marks are easy to generate, and the outer surface layer is formed by extrusion molding, so that the outer diameter tolerance zone is large. The tolerance zone of the outer diameter of the PC pipe 8 is large, so that the mold clamp is not tight or the outer diameter clamp mark of the PC pipe 8 is serious. The middle of the movable clamping block 2 and the second clamping block 4 is the spring gasket 3, in the clamping process, the spring gasket 3 elastically compensates the unqualified end part formed due to the large outer diameter tolerance zone of the PC pipe 8, the clamping force of the die is effectively improved, the processing difficulty caused by the large outer diameter tolerance of the PP pipe is solved, the qualified rate of the formed end part of the PP pipe is greatly improved, the mechanical injury is avoided, and the safety production is realized.
Finally, it should be noted that: although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that modifications and variations can be made in the embodiments or in part of the technical features of the embodiments without departing from the spirit and the scope of the invention.
