Description
Technical field
The invention belongs to field of mechanical technique, relate to a kind of sealing device, particularly a kind of sealing device of flat pipe.
Background technology
As shown in Figure 1, the tube wall of this flat pipe comprises just to two planar sections arranged and two segmental arcs between two planar sections existing flat pipe.When the part of flat pipe as radiator, need the two-port of flat pipe to close.
The existing sealing device for closed flat pipe port is generally by the clamping device for clamping flat pipe with to be located at above clamping device and the closing component with drift forms.In use, flat pipe horizontally set is also clamped by clamping device, the drift of closing component is displaced downwardly to and contacts with the upper side wall of flat pipe, and when drift continues to move down, the upper side wall of flat pipe is bent downwardly and with the lower wall tight abutment of flat pipe to be closed by the mouth of pipe.But there is two problems in above-mentioned way: 1, due in capping processes, mainly the upper side wall bending of flat pipe is to close the mouth of pipe, this can cause the wall for the closed mouth of pipe can be thinner, cause the wall for sealing easily damaged under the effect of external force, there is the problem that seal quality is poor; 2, closure part shape matching is irregular, has a strong impact on the aesthetic property of flat pipe.
Summary of the invention
The object of the invention is to there are the problems referred to above for existing technology, propose a kind of while realizing the sealing of flat pipe, also there is the sealing device of the flat pipe of better seal quality.
Object of the present invention realizes by following technical proposal: a kind of sealing device of flat pipe, it is characterized in that, comprise workbench and be located at two just right wheel die clamps of on workbench and position, two sidewalls that on two wheel die clamps, position is just right all has breach, and in each breach all axial restraint have one tubularly to take turns mould, and the position of two wheel moulds faces, each lateral wall of taking turns mould all offers annular groove, and annular groove is coaxial with wheel mould, described annular groove comprises two relative sidewalls of position and the diapire between two sidewalls, sidewall described in two is the compressive plane one that is plane, the compressive plane two of described diapire to be a cross section be circular arc, and the center of this compressive plane two has the extrusion head protruded in the form of a ring, extrusion head is coaxial and the cross section of this extrusion head is circular arc with wheel mould, described workbench is also provided with the clamping device for clamping flat pipe and be fixed with can drive respectively two-wheeled die clamp close to each other or mutually away from two actuators one.
Flat pipe comprises just to two planar sections arranged and two segmental arcs between two planar sections; When equipment actual production, the groove width of annular groove is slightly less than the distance between two planar section outer surfaces, and the radius of compressive plane two is slightly less than the radius with segmental arc outer surface.Add man-hour, on the table and clamped by clamping device, and now, the end of flat pipe is between two-wheeled mould for flat pipe horizontally set; Then the actuator one be positioned on the left of flat pipe works and drives the wheel die clamp being positioned at left side to move to make the side of flat pipe be inserted into annular groove; Along with constantly stretching into of flat pipe, planar section bends under the acting in conjunction of compressive plane one and extrusion head in the middle part of the flat pipe mouth of pipe, segmental arc bends under the acting in conjunction of extrusion head and compressive plane two in the middle part of the flat pipe mouth of pipe, and above-mentioned two places bending engages to close on the left of flat pipe; Then actuator one drive being positioned at left side is positioned at the wheel mould reset in left side, and the actuator one being and then positioned at right side drives and repeats above-mentioned process, to seal on the right side of flat pipe with the wheel mould on right side; In the process of sealing, owing to there is larger frictional force between wheel mould and flat pipe, wheel mould ceaselessly can be rotated in the process of movement, and by the radian of compressive plane two, above-mentioned two places bending is rebuild, to make whole sealing form comparatively saturated circular arc, improve the quality of sealing.
In the sealing device of above-mentioned flat pipe, the lateral wall of described compressive plane one and wheel mould passes through chamfered transition.
Adopt above-mentioned structure, flat pipe is inserted in wheel mould and plays good guide effect, to make flat pipe can arrive assigned address accurately all the time, thus improve the quality of sealing.
