Abstract
The utility model discloses a hand held corrugated pipe end making die, which consists of a die body and a mold core, wherein the die body is formed by hinging a left die body and a right die body, front and rear cylinder sections are arranged in the die body, a clamping ring is fixedly arranged at the rear end of the left die body or the right die body, and a bayonet is arranged between the front and rear cylinder sections; the mold core is a two-stage cylinder, a dummy club is arranged at the front end of the front-stage cylinder, and the rear-stage cylinder is inserted into the retaining ring. The utility model has the advantages of simple structure, easy operation, portability, and especially suitable site construction and maintenance, is mainly used for the end making of the connecting ends of stainless steel corrugated pipes, and can also be suitable for the end making of the connecting ends of other metal corrugated pipes.
Description
Technical field
The utility model relates to the mould class, and particularly a kind of hand held bellows is played a mouthful mould.
Background technology
Metal bellows is mainly used in water pipe or tap fixedlys connected, and at this moment, the bellows pipe end need be inserted in nipple, is threaded with connected water pipe or tap.Realize above-mentioned connected mode, then nipple one end will be provided with an interior bayonet socket, and the metal bellows link also will be provided with an outer bayonet socket that is complementary with it, so that card is kept a grip on nipple.The outer bayonet socket of existing metal bellows link is to beat jaws equipment by large-scale bellows to finish, this equipment is difficult to move to the job site operation, for the water supply line installing engineering, all be to determine the metal bellows length that connects at the construction field (site) mostly under the situation, thereby, need beat mouth at the scene.If can design a kind of small-sized hand held plays mouthful mould and just can satisfy its requirement.
Summary of the invention
The purpose of this utility model is to provide a kind of simple in structure, processing ease, hand held bellows easy to carry, that be particularly suitable for site operation and maintenance to play a mouthful mould.
The technical solution that the utility model proposed is such: a kind of hand held bellows is played a mouthful mould, comprise die body and core rod, described die body is by left die body and right die body is hinged forms, cylindrical section and back cylindrical section before being provided with in the die body, rearward end is fixed with snap ring in left side die body or the right die body, is provided with bayonet socket between preceding cylindrical section and back cylindrical section; Described core rod is the two-stage cylinder, and the cylindrical front end face of prime is provided with boss, and back level cylinder inserts in the described snap ring.
The back barrel bore is greater than preceding barrel bore in the described die body, and preceding barrel bore is greater than described bayonet socket internal diameter.The boss of core rod is a conical boss, mates with the bellows endoporus.
Compared with prior art, the utlity model has following beneficial effect:
The utility model is designed to the cylindrical ripple pipe of hand held and plays a mouthful mould, during operation, the metal bellows link is put into preceding cylindrical section of die body and cylindrical section front portion, back, promptly there is 2-4 joint ripple to place the back cylindrical section, bayonet socket blocks 2-4 joint groove, close then left and right die body and holding it hits the core rod exposed junction with hand hammer, promptly forms an outer bayonet socket that is formed by the compression of 2-4 joint ripple in the metal bellows connectivity port.As seen, this mould structure is simple, swift to operate, easy to carry, is specially adapted to site operation and maintenance engineering.
The utility model is mainly used in the mouth of beating of corrugated stainless steel tubing link, also is fit to the usefulness that other metal bellows links are beaten mouth.
Description of drawings
Fig. 1 is that the hand held bellows of an embodiment of the present utility model is played a mouthful mould structure schematic diagram.
The specific embodiment
By following embodiment the utility model is further elaborated.
Referring to shown in Figure 1, a kind of hand held bellows is played mouthful mould and is made up of die body 2 and core rod 1.Die body 2 is cylinder, is cut into two halves vertically, promptly forms right die body 2-1 and left die body 2-2, becomes the die body 2 of open-close type between left die body 2-2 and the right die body 2-1 by welding loose-leaf system hinge 4.Cylindrical section 2-3, back cylindrical section 2-5 are provided with bayonet socket 2-4 between these two sections before being provided with in the die body 2, and the rearward end of cylindrical section 2-5 is fixed with snap ring 5 behind right die body 2-1.Core rod 1 is the two-stage cylinder, and the front end face of prime cylinder 1-2 is provided with conical boss 1-3, and back level cylinder 1-1 passes prime cylinder 1-2 that snap ring 5 makes core rod 1 and inserts cylindrical section 2-5 and movable with it cooperation the behind the right die body.Barrel bore was greater than preceding barrel bore after this bellows was beaten in mouthful mould requirement die body 2, and preceding barrel bore is greater than bayonet socket 2-4 internal diameter.In the present embodiment, the internal diameter of corrugated stainless steel tubing 3 is Φ 13mm, and the internal diameter of cylinder 2-5 is Φ 19mm behind the die body, the internal diameter of cylinder 2-3 is Φ 16mm before the die body, bayonet socket 2-4 internal diameter is Φ 13.6mm, and core rod 1 prime cylinder 1-2 diameter is Φ 19mm, and back level cylinder 1-1 diameter is Φ 16.3mm.
During operation, rear portion the 3rd joint ripple of corrugated stainless steel tubing 3 links is placed behind the die body in the cylindrical section 2-5, the 3rd joint corrugation grooves is stuck on the bayonet socket 2-4, and all the other ripples of bellows 3 links are seated in before the die body in the cylindrical section 2-3.Closed left and right die body 2-2,2-1 and to hold, the another hand impacts core rod 1 exposed junction with hand hammer then, by guiding 1 moment of core rod is impacted forward, the last three joint ripples of corrugated stainless steel tubing 3 links are compressed into outer bayonet socket with the core rod conical boss 1-3 of corrugated stainless steel tubing 3 endoporus couplings.External diameter that should outer bayonet socket equals cylinder 2-5 internal diameter behind the die body.
Corrugated stainless steel tubing is mainly used the tube connector of used as water pipe, thereby at the construction field (site), has at first cut out one section bellows of Len req, at one end get an outer bayonet socket then, be inserted in two interior bayonet sockets and be positioned at inboard nipple, last, the bellows other end is got another outer bayonet socket.At this moment, two nipples on the pipe shaft are stopped by outer bayonet socket and can not break away from bellows, this corrugated stainless steel tubing promptly be at any time can be connected by water receiving pipe or tap thread seal.
