Abstract
The invention discloses a local heating device of a shape memory alloy spring. The device comprises a radiating fin and a spring fixing table arranged on the radiating fin, wherein the spring fixing table is provided with a spring clamping trough; a heating device the height of which is equal to that of the spring clamping trough is arranged close to the spring fixing table; and the edge of the spring fixing table is provided with a heat insulation sheet. When the device is used, a part to be heated, of the shape memory alloy spring is exposed out of the edge of the spring fixing table and is clamped by using the heat insulation sheet, and the other part of the shape memory alloy spring is fastened in the spring clamping trough; the heating device is matched with the spring fixing table; in the process of locally heating the shape memory alloy spring, the local superelasticity of the shape memory alloy spring is removed according to the distance, temperature and heating time of heating and fixing the partial spring exposed out of the spring fixing table controlled by selecting different heating devices, thereby reaching the purpose of deformation processing at room temperature and simultaneously realizing the purposes of not enlarging heating range and avoiding the spring property influenced by over-high whole spring temperature.
Description
Technical field
The present invention relates to a kind of metal heat treatmet device, particularly a kind of area heating installation of shape memory alloy spring.
Background technology
In some course of processing to shape memory alloy spring, need carry out this complete processing of partial heat treatment to spring, for example need that shape memory alloy spring is carried out local deformation and handle.Because shape memory alloy has super-elasticity, we use shape memory alloy is exactly in order to utilize its super-elasticity under many circumstances, but in some cases, we need be for further processing to shape memory alloy spring, shape memory alloy can not produce the deformation that we want under the normal temperature, this just need heat-treat the part of shape memory alloy spring under specific temperature, makes it eliminate super-elasticity.In the prior art, owing to lack special area heating installation at shape memory alloy spring, when adopting naked light etc. that the spring part is heated, because can not accurately control heating location causes not needing to heat the position and also is subjected to high temperature " scald ", thereby the super-elasticity of losing has a strong impact on the overall performance of shape memory alloy spring.And because the heat conductance of shape memory alloy spring self in to local heating, can cause the shape memory alloy spring bulk temperature to promote, can influence the performance of shape memory alloy spring self when serious equally.
Summary of the invention
In view of this, the area heating installation that the purpose of this invention is to provide a kind of shape memory alloy spring, use this device can guarantee that the part that only need heat shape memory alloy spring carries out heat, avoid enlarging heated perimeter, guarantee the quick heat radiating of whole shape memory alloy spring in the partial heat treatment process simultaneously, avoid partial heat treatment that whole spring performance is impacted.
The objective of the invention is to be achieved through the following technical solutions: a kind of area heating installation of shape memory alloy spring, comprise radiator element and the spring stationary platen that is arranged on the radiator element, the spring stationary platen is provided with spring card slot, near the spring stationary platen heating unit contour with spring card slot is set, described spring stationary platen edge is provided with heat insulation thin slice.
Further, described heating unit comprises a plurality of well heater monomers, and each well heater monomer is arranged along spring stationary platen edge and is linear structure, and each well heater monomer is controlled separately;
Further, described radiator element and the seamless link removably of spring stationary platen;
Further, described heat insulation thin slice is fixedly installed on spring stationary platen edge removably.
Further, the described well heater monomer far-infrared ceramic electric heater that is Controllable Temperature.
Further, described radiator element has aluminum alloy materials to make.
Beneficial effect of the present invention: the area heating installation of shape memory alloy spring of the present invention, comprise radiator element and the spring stationary platen that is arranged on the radiator element, the spring stationary platen is provided with spring card slot, near the spring stationary platen heating unit contour with spring card slot is set, described spring stationary platen edge is provided with heat insulation thin slice.During use, the part of shape memory alloy spring processing to be heated is exposed spring stationary platen edge, adopt heat insulation thin slice stuck, rest part is fastened in the spring card slot, heating unit and spring stationary platen are used, shape memory alloy spring is being carried out in the process of partial heat treatment, according to selecting different heating device control heating and the distance that is fixed on the part of exposed portions serve spring on the spring stationary platen, the time of temperature and heating, remove the super-elasticity of shape memory alloy spring part, reach the purpose that to carry out deformation processing at normal temperatures, realize not enlarging heated perimeter simultaneously and avoid the spring bulk temperature too high and influence the purpose of its performance.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further described:
Fig. 1 is the structural representation of the area heating installation of shape memory alloy spring of the present invention;
Fig. 2 is the use state graph of the area heating installation of shape memory alloy spring of the present invention.
Embodiment
Fig. 1 is the structural representation of the area heating installation of shape memory alloy spring of the present invention; Fig. 2 is the use state graph of the area heating installation of shape memory alloy spring of the present invention.As shown in the figure: the area heating installation of the shape memory alloy spring of present embodiment, comprise radiator element 1 and the spring stationary platen 2 that is arranged on the radiator element, the spring stationary platen is provided with spring card slot 3, near the spring stationary platen heating unit contour with spring card slot is set, described spring stationary platen edge is provided with heat insulation thin slice 4.During use, the part of the processing to be heated of shape memory alloy spring 6 is exposed spring stationary platen edge, adopt heat insulation thin slice 4 that it is stuck, rest part is fastened in the spring card slot, heating unit and spring stationary platen are used, shape memory alloy spring is being carried out in the process of partial heat treatment, according to selecting different heating device control heating and the distance that is fixed on the part of exposed portions serve spring on the spring stationary platen, the time of temperature and heating, remove the super-elasticity of shape memory alloy spring part, reach the purpose that to carry out deformation processing at normal temperatures, realize not enlarging heated perimeter simultaneously and avoid the spring bulk temperature too high and influence the purpose of its performance.
As the further improvement to above-described embodiment, described heating unit comprises a plurality of well heater monomers 5, and each well heater monomer is arranged along spring stationary platen edge and is linear structure, and each well heater monomer is controlled separately.The well heater that monomer structure is set and controls separately can heat object point targetedly, makes to add thermal target according to accurately, prevents that large-area thermal radiation from causing the heat collapse to non-hot spots.
