Description
Technical field
The utility model relates to a kind of expanding device, particularly relates to a kind of pipe fitting expanding device for carrying out enlarging to pipe port.
Background technology
When being connected different pipe fitting in industry with life, especially connection metal pipe fitting, needs interconnective pipe port bore to expand, and connects, meet design requirement to realize pipe fitting comparatively efficiently.Metal tube due to its intensity higher, cannot image height molecule pipe fitting expanding easy like that, special flaring tool is needed to realize, currently available technology often adopts professional equipment or easy structure mouth expander, but professional equipment cost is high and complex structure heavy, and easy structure mouth expander can only carry out enlarging to thin-wall part, for the workpiece that tube wall is thicker, workpiece as 1 ~ 2mm carries out enlarging, and then efficiency is lower, cannot meet batch production needs.
Summary of the invention
It is simple that the technical problems to be solved in the utility model is to provide a kind of structure, and the workpiece thicker to tube wall can realize high-effective and labour-saving, the device of the port enlarging of quick batch production.
The technical solution of the utility model is: a kind of pipe port expanding device, comprise two calipers and be arranged on support on caliper and addendum cone, caliper is provided with semi-circular recesses, and in caliper, the diameter of the first half semi-circular recesses is greater than the diameter of the latter half semi-circular recesses; The side of caliper is fixedly connected with support, and opposite side corresponding with support on caliper is provided with bolt hole, and two calipers are symmetrical about bracket mirror; Two calipers are connected by support, the support of a caliper is provided with groove, the support of another caliper is provided with the axle of protrusion, the axle protruded is arranged in a groove, bearing pin passes the axle of groove and protrusion from top to bottom successively, the lower end of bearing pin is provided with split pin, and support freely can rotate around bearing pin; Two calipers fasten to around holder pivots and form hinge body together, and bolt, through the bolt hole on two calipers, is locked with quick locknut; The semi-circular recesses composition pilot hole of two caliper the first half, the semi-circular recesses composition clamping hole of two caliper the latter halfs, clamping hole inwall is provided with screw thread, and the diameter of clamping hole is slightly less than the diameter of holding workpiece; Addendum cone is arranged in pilot hole, and pilot hole and addendum cone adopt matched in clearance; Taper hole mould is provided with between pilot hole and clamping hole.
The beneficial effects of the utility model: the utility model structure is simple, can be good at ensureing the concentricity between addendum cone and processing pipe fitting, produce momentum during hammering addendum cone large simultaneously, can effectively realize the pipe port enlarging of tube wall thickness at below 2mm, high-effective and labour-saving, and can fast produce in batches.

Detailed description of the invention
As depicted in figs. 1 and 2, a kind of pipe port expanding device, comprise two calipers 1, be arranged on support 3 on caliper 1 and addendum cone 2, caliper 1 is provided with semi-circular recesses, and in caliper 1, the diameter of the first half semi-circular recesses is greater than the diameter of the latter half semi-circular recesses; The side of caliper 1 is fixedly connected with support 3, and opposite side corresponding with support 3 on caliper 1 is provided with bolt hole 12, and two calipers 1 are symmetrical about support 3 mirror; Two calipers 1 are connected by support 3, the support 3 of one of them caliper 1 is provided with groove, the support 3 of another caliper 1 is provided with the axle of protrusion, the axle protruded is arranged in a groove, bearing pin 4 passes the axle of groove and protrusion from top to bottom successively, the lower end of bearing pin 4 is provided with split pin 5, and support 3 freely can rotate around bearing pin.Two calipers 1 are combined together composition hinge body 13 around support 3 rotary buckle, and bolt 6, through the bolt hole 12 on two calipers 1, is locked with quick locknut 7, produces chucking power to processing work; The semi-circular recesses composition pilot hole 8 of two caliper 1 the first half, the semi-circular recesses composition clamping hole 9 of two caliper 1 the latter halfs, clamping hole 9 inwall is provided with screw thread, the diameter of clamping hole 9 is slightly less than the diameter of holding workpiece 10, with increasing friction force, thus be conducive to clamping hole 9 better clamping holding workpiece 10; Addendum cone 2 is arranged in pilot hole 8, and addendum cone 2 axially can move freely in pilot hole 8, and pilot hole 8 and addendum cone 2 adopt matched in clearance, and when can prevent pipe fitting expanding, port pressure partially; Taper hole mould 11 is provided with between pilot hole 8 and clamping hole 9.
During use, the position of enlarging holding workpiece 10 is needed to be placed in the clamping hole 9 of one of them caliper 1, determine to need flared part height not higher than the upper edge of taper hole mould 11, then another caliper 1 is rotated around bearing pin 4, two calipers 1 are made to fasten to together, then clamp by bolt 6 and quick locknut 7 pairs of holding workpieces 10, again addendum cone 2 is put into the pilot hole 8 that two calipers 1 form, the tool impact addendum cone 2 of large momentum can be produced by iron hammer etc., namely the processing to holding workpiece 10 enlarging can be completed, after enlarging completes, addendum cone 2 is taken out, open quick locknut 7, launch two calipers 1, take out holding workpiece 10.
