Description

Winding bow and composite hose making machine

Technical Field

The utility model relates to the technical field of composite hose manufacturing equipment, in particular to a winding bow.

Background

The composite hose is a pipe material with a typical structure different from a rubber pipe and a metal pipe, and the pipe body structure of the composite hose comprises an inner spiral steel wire, an inner liner layer, a reinforcing layer, an anti-aging layer and an outer spiral steel wire from inside to outside. Wherein, the inner spiral steel wire and the outer spiral steel wire (collectively referred to as steel wire components in the application) are used as supporting components and are formed by winding stainless steel wires; the inner liner layer selects a corresponding functional film according to the characteristics of conveyed materials; the reinforcing layer is typically a fibrous layer which, in cooperation with the aforementioned support members, provides the hose with compressive strength; the anti-aging layer is made of anti-wear anti-aging colorful PVC.

Due to the structural characteristics of the composite hose, the composite hose still has better fracture resistance and leakage resistance in the worst environment, can not burst, can easily process the transmission work of gasoline, diesel oil, crude oil and various chemical liquids, and can still keep higher flexibility even in cold weather. Compared with rubber pipes and metal pipes, the high-strength static electricity dissipation pipe has the advantages of light weight, strong toughness, easiness in carrying, flexibility in use, high temperature resistance, low temperature resistance, ageing resistance, no deformation, corrosion resistance and the like, and meanwhile, the inner spiral steel wire part of the high-strength static electricity dissipation pipe is connected into the pipe joint, so that the high-strength static electricity dissipation pipe also has reliable static electricity dissipation performance, and is widely applied.

When the composite hose is wound, one of the core difficulties is the winding of the steel wire parts, and if the pitch of the wound steel wire is not accurately controlled, the pitch change and the like are generated, and the sealing property, the pressure resistance and the like of the hose are directly influenced. At present, the winding of the steel wire part is realized through a winding bow, the bow body of the winding bow is in a semi-circular arc shape, and two ends of the bow body are respectively provided with a rolling grooved wheel so as to press the steel wire. The tail end of one end of the bow body forms a handle end which is connected with the winding machine so that the relative position of the bow body and the machine mandrel can be kept, and during winding operation, the machine mandrel rotates, the bow body moves along with the winding machine, and the required steel wire part is wound and formed.

The drawback of current wire winding bow has:

1. because only two rolling line grooved pulleys are provided, the freedom degrees of the inner side and the outer side of the machine table core rod are only limited, and the machine table core rod is a single-end driven long core rod in the winding process, the tail part of the machine table core rod is easy to throw, and a winding bow is easy to jump up and down, so that operators are required to have extremely rich experience;

2. because only two rolling line grooved pulleys are provided, the two rolling line grooved pulleys are greatly stressed, the bearings of the two rolling line grooved pulleys are easy to damage, once one rolling line grooved pulley is damaged, a wire jumping phenomenon is easy to occur, namely, a steel wire is jumped off from the rolling line grooved pulley, at the moment, the steel wire is extruded and deformed, an operator needs to suddenly stop a machine, and a deformed area needs to be uncoiled and straightened and then is rewound; if the jumper wire occurs when the outer steel wire is wound, the anti-aging layer can be damaged;

3. due to the defects of the previous 1 and 2, the existing winding bow can only be operated manually, and is not suitable for automatic operation.

Example 1

Referring to fig. 1 to 5, the present invention discloses a wire winding bow for winding a wire member of a composite hose 400 on a mandrel, which includes three wire winding grooved pulley sets 100, three connecting frames 200, and a handle end 300.

Referring to fig. 3, along the cross-sectional direction of the mandrel, the three rolling groove wheel sets 100 are distributed in an equilateral triangle, a winding area for winding the steel wire component is formed between the three rolling groove wheel sets 100, and the rolling grooves 110 of each rolling groove wheel set 100 are distributed according to the pitch of the steel wire component (i.e., if the pitch of the steel wire is 10mm, each rolling groove wheel 110 is distributed according to the pitch of 10 mm).

Each connecting frame 200 is connected to the seat body of the adjacent rolling raceway pulley set 100 (i.e. each connecting frame 200 is also distributed in a triangular shape to connect each seat body); a certain link frame 200 is provided with a hinge member 210 so that the winding area can be opened or closed; one of the connection frames 200 is provided with a locking member 220 to lock it when closing the winding area and to release it when opening the winding area. The hinge member 210 and the locking member 220 may be located on the same connecting frame 200 or different connecting frames 200, and in this embodiment, for the sake of simple structure and easy operation, the two connecting frames are located on different connecting frames 200.

The shank 300 is connected to the remaining one of the connection frames 200, and the shank 300 is connected to the winding machine to prevent the wire winding bow from rotating following the core rod.

For convenience of description, the present invention defines the front end of the core rod 500 (i.e., the position where the headstock is located) as the front and the end of the core rod 500 as the rear.

Therefore, during operation, the locking piece 220 is opened, the winding area can be opened under the action of the hinge piece 210, the locking piece is sleeved on the machine table mandrel after being opened and the winding area is closed, and at the moment, the locking piece 220 is locked; one end of the steel wire sequentially passes through the wheel groove of each thread rolling grooved wheel 110 from back to front and is locked on the machine table core rod after being wound; starting the machine table core rod, rotating the machine table core rod, dragging the wire feeding disc to rotate for wire feeding, and then, enabling the wire winding bow to walk along the length direction of the machine table core rod until the steel wire component 410 is wound; after completion, the end of the wire member 410 is wound with an adhesive tape to prevent the release, and the end wire is cut. If the other types of wire winding bows need to be replaced, the locking member 220 is opened, and the wire winding bow is taken down or removed, so that the operation is finished.

Referring to fig. 1, in the present embodiment, the locking member 220 includes a fixing portion 221 and a locking portion 222. The fixing portion 221 includes a fixing base 2211 and an inverted L-shaped plate 2212 connected to two sides of the base, the locking portion 222 forms a pulling plate 2221, and the inverted L-shaped plate 2212 is overlapped with the pulling plate 2221 and then locked by bolts. The structure is simple and reliable, and accidental loosening can not occur in the process of winding the steel wire.

To facilitate the pre-overlapping of the fixing portion 221 and the locking portion 222, an open pull rod groove 22211 is formed at the center of the pull plate 2221; the fixing portion 221 further includes a pull rod 2213, one end of the pull rod 2213 is a hinged end and hinged in the fixing seat 2211, and the other end is a clamping end and clamped in the pull rod groove 22211.

In this embodiment, the hinged end of the pull rod 2213 is a ball end. The connecting end of the rod 2213 is conveniently matched with the rod groove 22211 for adjustment, and comprises a screw 22131 and a mushroom head nut 22132 screwed on the screw 22131, and a ball head end convenient for self-positioning is actually formed by the mushroom head nut 22132 screwed on the screw 22131, and the effective length of the rod 2213 can be conveniently adjusted by screwing so as to be matched with the rod groove 22211.

In this embodiment, the number of the rolling line sheaves 110 on each rolling line sheave group 100 is 3, that is, a total of 9 rolling line sheaves 110. The arrangement of the multiple thread rolling sheaves 110 reduces the load force of each thread rolling sheave 110 and is durable, and the resilience of the steel wire is effectively inhibited, so that the steel wire parts 410 are uniform in size (the size comprises the thread pitch and the diameter), and the performance of the pipe fitting is improved.
