Abstract
The utility model discloses the swollen mould of a kind of opening profile, it comprises base (1), wallboard (2), die (3), side internal mold (4), punch (5), fulcrum post (7), back-moving spring (8) and die adjustment screw (9), die (3) is arranged on base (1), wallboard (2) is arranged on base (1), wallboard (2) is positioned at die (3) both sides, side internal mold (4) is arranged on wallboard (2) by fulcrum post (7), side internal mold (4) can wraparound ship and resell on another market (7) rotate, back-moving spring (8) is provided with in wallboard (2), punch (5) is arranged at side internal mold (4) inner side, die (3) and side internal mold (4) coordinate formation die cavity.The beneficial effects of the utility model are: this device may be used for the swollen type process of opening profile, and without dead angle when making workpiece expand by the aggregate motion becoming circular motion to add translation stretching Trajectory Design, this device has the advantages such as structure is simple, reliable clamping.
Description
Technical field
The utility model relates to a kind of swollen mould of cold roll forming production line, particularly the swollen mould of a kind of opening profile.
Background technology
Cold rolling opening profile be with cold roll forming milling train, a kind of cross section of thin plate rolling is not closed and the banded section bar of length direction continuous print.According to requirements, by different length, opening profile will be cut off during production, and cross section expansion one end of opening profile being about the part of 100mm swells, be beneficial to opening profile and phase lap button is installed.Mould described in the utility model is the device that the opening profile cross section supporting with milling train expands swollen type.
The central angle that the position relationship of several due to opening profile accounts for its inscribed circle has been greater than 180o.Therefore, swollen type work can not be completed with single reciprocating manner.If allow internal mold do aggregate motion, then no matter internal mold is along what direction translational, and its core always changes from small to big (namely outer perimeter is elongated), cannot avoid appearance one section of vacancy between several pieces of internal molds.
On the other hand, in order to save material and easy to process during rolling opening profile, the section bar rolled out can not trimming again, flanging material required when that is not leaving the swollen type of mould.Result makes it in swollen type process, and the both sides do not closed can not meet should can fix again the requirement of section bar by swollen type.So the mode of the swollen type of flanging cannot be used to fulfil assignment.
As mentioned above, in order to meet the requirement of swollen type, the flanging way choice of the motion mode of internal mold and structure and section bar just seems most important, and this is the utility model key problems-solving just also.Traditional swollen mould is roughly divided into two classes.One is be that enclosed (as: cross section is rectangle by cross section, circular etc.) light-wall pipe local swells, because its closed section bar easily accomplishes to make its each stress balanced and equal when expanding outwardly, so, swollen type work can be completed with soft mode (as: silica gel, liquid etc.).And opening profile is the section bar of open type, due to jagged, the uniformity of tension cannot be ensured, add section bar and also cannot close in the longitudinal direction, therefore, soft mode cannot be used to meet swollen type requirement.Two are, in traditional method, by further expansion after plate stretch, this also belongs to enclosed construction, and also will leave the material needed for flanging when stretching, so, also can not meet needed for the swollen type of opening profile.
Utility model content
The purpose of this utility model is the shortcoming overcoming prior art, the swollen mould of opening profile that a kind of structure is simple, can effectively clamp is provided, the cooperation that is protruding by flanging and flanging groove of this device makes opening profile be compressed, and rotates by side internal mold the uniformity that force ensures tension.
The purpose of this utility model is achieved through the following technical solutions: a kind of opening profile is swollen mould, it comprises base, wallboard, die, side internal mold, punch, fulcrum post, back-moving spring and die adjustment screw, die is arranged on base, wallboard is arranged on base, wallboard is positioned at die both sides, and side internal mold is arranged on wallboard by fulcrum post, is provided with back-moving spring in wallboard, punch is arranged at inside the internal mold of side, and die and side internal mold coordinate formation die cavity.
Described wallboard is provided with die adjustment screw.
Described die is divided into left and right two pieces.
Described wallboard is provided with charging mould.
The utility model has the following advantages: the utility model may be used for opening profile swollen type process, this apparatus structure is simple, reliable clamping, and the tension that workpiece expand is even, this device can adapt to workpiece size excursion comparatively greatly, flexible operation.

Fig. 2 is the rearview of the swollen mould of a kind of opening profile.
In figure, 1-base, 2-wallboard, 3-die, 4-side internal mold, 5-punch, 6-workpiece, 7-fulcrum post, 8-back-moving spring, 9-die adjustment screw, 10-support column, 11-cover plate, 12-charging mould.
Detailed description of the invention
Be further described the utility model below in conjunction with accompanying drawing, protection domain of the present utility model is not limited to the following stated:
As shown in Figure 1, the swollen mould of a kind of opening profile, it comprises base 1, wallboard 2, die 3, side internal mold 4, punch 5, fulcrum post 7, back-moving spring 8 and die adjustment screw 9, die 3 is arranged on base 1, wallboard 2 is arranged on base 1, wallboard 2 is positioned at die 3 both sides, in the present embodiment, described die 3 is divided into a left side, right two pieces, wallboard 2 is provided with die adjustment screw 9, it is left that die adjustment screw 9 can adjust die 3, spacing between right two pieces, in the present embodiment, described wallboard 2 is provided with charging mould 12, side internal mold 4 is arranged on wallboard 2 by fulcrum post 7, side internal mold 4 can wraparound ship and resell on another market 7 rotations make workpiece 6 compacted and stretch, back-moving spring 8 is provided with in wallboard 2, punch 5 is arranged at inside side internal mold 4, die 3 and side internal mold 4 coordinate formation die cavity.
The course of work of the present utility model is as follows: base 1 and wallboard 2 are welded as a whole, die 3 is divided into left and right two pieces, when the varied in thickness of workpiece 6 and amount of tension change, screw 9 can be adjusted with die and different material thickness sizes and different amount of tension are adapted to its position adjustment.The effect of charging mould 12 mainly guides workpiece 6 to enter die 3 and the position of fixation workpiece 6 in die 3, and allows workpiece 6 to have certain slippage in charging mould, in order to avoid thinning or break during material extending.
Two pieces of side internal molds 4 are contained on the wallboard 2 of both sides by fulcrum post 7 respectively, when punch 5 moves down, punch 5 promotes two pieces of side internal molds 4 and rotates around the fulcrum post 7 of both sides and extrude to both sides respectively, therefore workpiece 6 can not be subjected to displacement when punch 5 stretches downwards, after swollen type completes, punch 5 moves upward, and side internal mold 4 resets under the effect of back-moving spring 8, and workpiece departs from impaction state.
