Abstract

The utility model discloses a manual bending device for spiral copper pipes. The manual bending device comprises a cylindrical winding column (1). An arc-shaped spiral groove (11) is formed in the outer wall of the winding column (1), a spiral fastener (12) is formed above and below the spiral groove (11) on the winding column (1), the pitch of the fastener (12) is equal to that of the spiral groove (11), a spiral retainer (2) is screwed with the fastener (12) and welded with a handle (21), and cylindrical plugs (13) are formed at two ends of the winding column (1) and plugged in bases (3) respectively. The manual bending device for the spiral copper pipes is simple in structure and convenient to use. By the manual bending device, except acting force applied to winding, other acting force applied to capillary copper pipes during winding is eliminated, lengthening and flattening of the capillary copper pipes during winding are reduced.

Description

A kind of manual bending device of spiral copper pipe

Technical field:

The utility model relates to the technical field of bending device, more specifically to a kind of manual bending device of spiral copper pipe.

Background technology:

Cryogenic pump is the vavuum pump that utilizes low-temperature surface condensed gas, claims again condenser pump.And in cryogenic pump, usually use spiral helicine copper capillary tube, the method of existing cryogenic pump copper capillary tube curl is the manual moulding that rotates on a cylinder, but the method is had relatively high expectations to staff's, stressed wanting evenly in the process of rotating, not so easy-to-draw copper long capillary or flattening copper capillary tube, thereby cause copper capillary tube logical, what wind up is spiral-shaped also each identical simultaneously.

Utility model content:

The purpose of this utility model is exactly the deficiency for prior art, and a kind of manual bending device of spiral copper pipe is provided, and it is simple in structure, for copper capillary tube coiling work band facility.

Technology solution of the present utility model is as follows:

A kind of manual bending device of spiral copper pipe, comprise columniform around post, form the helicla flute of circular arc around the outer wall of post, helicla flute upper and lower sides on post, form spiral helicine deck, the pitch of deck equates with spiral fluted pitch, is bolted with spiral helicine block on described deck, is welded with handle on block, the described two ends around post form columniform plug, and plug is plugged on base.

Described deck is made up of the contiguous block of two groups of L-type shapes, and contiguous block lays respectively at the two ends up and down of helicla flute notch, and described block cross section is C type, and the two ends sleeve of block is on the contiguous block of deck; Described spiral fluted notch is semicircle, and block medial surface and the spacing between column outer wall equal the radius of helicla flute notch.

The diameter of the described plug around post two ends is less than the diameter around post, forms the open slot that runs through plug two opposite side walls on plug, forms the slot of plug same shape on the base of attachment plug.

The beneficial effects of the utility model are:

1, it provides a kind of easy manual copper pipe bending device, it is simple in structure, easy to use, avoid hand active force other to the copper capillary tube in winding process except rotating, thereby reduced copper long capillary in winding process and elongate, flatten the generation of phenomenon.

2, the spiral helicine copper capillary tube of its coiling has reduced because of the workload that copper long capillary is elongated, flattening is reprocessed, thereby has improved production efficiency, has saved production cost.

3, it adopts mechanical coiling, has unified the pitch of the copper capillary tube of its coiling, thereby makes the shape of finished product have uniformity.

Detailed description of the invention:

Embodiment: see shown in Fig. 1 to 4, a kind of manual bending device of spiral copper pipe, comprise columniform around post 1, form the helicla flute 11 of circular arc around the outer wall of post 1, helicla flute 11 upper and lower sides on post 1, form spiral helicine deck 12, the pitch of deck 12 equates with the pitch of helicla flute 11, on described deck 12, be bolted with spiral helicine block 2, on block 2, be welded with handle 21, the described two ends around post 1 form columniform plug 13, and plug 13 is plugged on base 3.

Described deck 12 is made up of the contiguous block of two groups of L-type shapes, and contiguous block lays respectively at the two ends up and down of helicla flute 11 notches, and described block 2 cross sections are C type, and the two ends sleeve of block 2 is on the contiguous block of deck 12; The notch of described helicla flute 11 is semicircle, and block 2 medial surfaces and the spacing between post 1 outer wall equal the radius of helicla flute 11 notches.

The diameter of the described plug 13 around post 1 two ends is less than the diameter around post 1, forms the open slot 14 that runs through plug 13 two opposite side walls on plug 13, forms the slot 31 of plug 13 same shapes on the base 3 of attachment plug 13.

Operation principle: the winding method of copper capillary tube, now by the slightly bending of linear capillary head, its open slot 14 that is placed in plug 13 part are placed in helicla flute 11, the upper block 2 that is spirally connected again, hand-held handle 21 rotary blocks 2 carry out coiling, and after coiling, derotation goes out block 2, extract again around post 1, the copper capillary tube of hand-held coiling rear screw shape, rotation is around post 1, and back-out turns around.Thereby because this simple and easy bending device simple in structure is provided, avoid hand active force other to the copper capillary tube in winding process except rotating, thereby reduced copper long capillary in winding process and elongate, flatten the generation of phenomenon.
