Description
Technical field
The utility model relates to floor heating pipeline groove special molding assembling die field, more particularly, relates to a kind of floor heating pipeline Slot shaping assembling die.
Background technology
Floor heating has become the main flow of domestic heating system, but traditional floor heating mounting means is called wet type floor heating, its technique is the on-the-spot compound of multilayer, surface layer cast sandstone concrete is as load-bearing and heat transfer medium, construct very loaded down with trivial details, energy consumption is very high, fuel factor is chronic, account for building storey height about 10 centimeters, larger to building carrying.For many deficiencies of wet type floor heating technique, in recent years there is dry floor heating technical products, i.e. dry-type floor warming device, use for dry floor heating heating occasion, overcome the some shortcomings of wet type floor heating technique, existing dry-type floor warming device mainly comprises thermal insulation layer and is placed in the heat-conducting layer above thermal insulation layer, heat-conducting layer is provided with the groove holding floor heating pipeline, be called floor heating pipeline groove, floor heating pipeline groove generally is " U " shape groove, floor heating pipeline is embedded in floor heating pipeline groove during installation, tilt in use to prevent floor heating pipeline, glue overlay film must be used floor heating pipeline and the fixation of floor heating pipeline groove, or use pipe clamp to be fixed on by floor heating pipeline in floor heating pipeline groove, construct comparatively loaded down with trivial details, also have impact on the heat transfer property of dry floor heating layer, and existing dry-type floor warming device structure is generally the production of small size mold, cause on-site consolidation construction workload still larger, and packaging and transport comparatively bother.
In dry-type floor warming device, heat-conducting layer adopts aluminium sheet to make usually, because aluminium sheet ductility is not good, easily causes floor heating pipeline groove to occur fold when direct punching press floor heating pipeline groove, rough and uneven in surface, and floor heating pipeline easy tilting in diabatic process is even ejected; And for dull and stereotyped aluminium sheet, pleated portions branch causes heat radiation uneven, thus cause heating effect uneven in temperature, cause user uncomfortable, even bring the waste of the energy, therefore, how overcoming the fold that floor heating pipeline groove occurs in process, is the technical barrier needing solution in prior art badly.
On the other hand, as shown in Figure 1 and Figure 2, in order to prevent floor heating pipeline from tilting in use in prior art, heat-conducting layer 1 is provided with the floor heating pipeline groove 101 that cross section is " Ω " shape.At present, primarily of bending machine tool or press machine tool, bending force is applied to heat-conducting layer 1, realize the flexural deformation of heat-conducting layer 1, to obtain required floor heating pipeline groove 101.In existing bending techniques, single angle that numerical control bending lathe is applicable to be less than 100 degree of scopes is shaped, and has good versatility, but is difficult to be bent to form the floor heating pipeline groove 101 that cross section is " Ω " shape; When taking press machine tool stamping, the floor heating pipeline groove 101 of " Ω " shape of given size need could be formed through stamping machine Multi-step forming, and for improving the precision of shape angles, need after punching press, carry out manual school shape or compensate the shape angles of mould, meanwhile, under normal-temperature, formation of parts resilience is larger, be difficult to control angle precision, therefore, how disposable accurately process floor heating pipeline groove, be the technical barrier needing solution in prior art badly.Meanwhile, floor heating pipeline groove is offered along the length direction of heat-conducting layer, and the length of floor heating pipeline groove is longer, and how making the size of floor heating pipeline groove each position in the longitudinal direction be consistent, is also the technical problem needing emphasis to consider.
About how to carry out press shaping die to metalwork, in prior art, existing related art scheme is open, as Chinese Patent Application No.: 2013105283746, the applying date is on October 30th, 2013, invention and created name is: a kind of Ω shape metalwork bending mould and manufacturing process thereof, for solving existing bending, the weak point of press-bending and hot bending process, this application case provides a kind of Ω shape metalwork bending mould and manufacturing process thereof, mould is by punch, die, turning cylinder and base composition, die is connected to chassis interior by turning cylinder through left and right sides rotational axis hole, in punching course, around axis rotation, to punch realize surpass 180 degree coated, implement coated to 90 degree, Ω shape both sides bent angle simultaneously, complete bending.Thus, this application case drives die to rotate by punch travel, and be shaped 180 degree of angle of bend, having the advantage of the double school shape that is shaped, greatly reducing production cost, improve production efficiency.But this application case also has the following disadvantages: the bending die structure in this application case is more complicated, and process operation is more loaded down with trivial details; And offer due to the length direction of floor heating pipeline groove along heat-conducting layer, and the bending mould in this application case is only applicable to the metalwork bending machining of one fixed width, is difficult to the actual processing request meeting floor heating pipeline groove.
Chinese Patent Application No.: 2013106201813, the applying date is on November 29th, 2013, invention and created name is: pipe collar diel, this application case discloses a kind of pipe collar diel of mould applications, comprise cylindrical male and die shoe, cylindrical male radial direction is connected with die shank, and die shoe is hinged with symmetrically arranged a pair swinging cavity die, is connected with spring between the forming ends of swinging cavity die and die shoe; The die cavity that swinging cavity die is formed and cylindrical male match; Die shoe is also provided with the locating piece of location blank.But, this application case also has the following disadvantages: the diel in this application case for be the processing of pipe collar, because the width of pipe collar is less, and pipe collar is mainly used in locking pipe, as long as can be processed to form " Ω " shape, the requirement on machining accuracy for self is not high; On the other hand, floor heating pipeline groove is offered along the length direction of heat-conducting layer, the floor heating pipeline groove in the longitudinal direction size of each position needs to keep consistency, can embed smoothly in floor heating pipeline groove to make floor heating pipeline, therefore, the diel in this application case is difficult to the actual processing request meeting floor heating pipeline groove.
