Description

Heater before the assembling of interference fit workpiece coordinates
Technical field
The utility model relates to a kind of heater, the heater before specifically a kind of interference fit workpiece assembling coordinates.
Background technology
At present in field of machining for to realize being fastenedly connected between machine components, the mode that conventionally adopts interference fit to connect replaces welding.Interference fit is the actual size that the actual size of spindle is greater than hole, has certain magnitude of interference after assembling, there is no the part fit form of relative motion between the two.The assembling mode of interference fit part generally have press-fit, hot charging and cold charge.Press-fit method and be divided into again hammering method and forcing press assembling, the magnitude of interference is hour use hammering method, and the magnitude of interference adopts forcing press assembling when slightly large.When the magnitude of interference is larger, hot-mounting process can be adopted, for the workpiece that is difficult for heating, cold charge can be carried out.
When workpiece is carried out to hot charging, first to boil by oil, baking box, flame or electromagnetic induction etc. carry out homogeneous heating (institute's heating-up temperature should lower than the temperature of heated object material) to workpiece, and diameter of work trace is swollen.Yet adopt that oil boils, baking box or flame is when heat, heating time is longer, inefficiency, and waste material and the energy; And adopt induction type heating to have certain restriction to the size of workpiece.
Utility model content
The purpose of this utility model is just to provide the heater before a kind of interference fit workpiece assembling coordinates, to solve existing mode of heating inefficiency and to have the problem of using limitation.
The utility model is achieved in that the heater before a kind of interference fit workpiece assembling coordinates, and comprises some for surrounding the heating unit that is heated workpiece; Described heating unit is, in the top and bottom of substrate surface, the end pillar that one row stands on described substrate surface is respectively set, the two described end of row pillars are relative up and down, between the space of the described end of a row pillar, be connected to respectively the some ends stationary pipes parallel with the plate face of described substrate, an affixed electric heating element in two described end stationary pipes opposing upper and lower.
At the plate face middle part of described substrate, be provided with at least one row stand on described substrate surface and with described end pillar middle bilge cod opposing upper and lower, between the space of described middle bilge cod, be connected to respectively the some middle parts stationary pipes parallel with the plate face of described substrate, described electric heating element passes from the stationary pipes of described middle part.
On one side of described substrate lateral surface, be provided with fixedly link, at its another side, be provided with butt hook, between adjacent heating unit by the butt hook on two substrates and fixedly link link together.
Described substrate is cambered plate or metallic plate that can bending.
Between the plate face between the plate face of described end stationary pipes and described substrate and at described middle part stationary pipes and described substrate, be provided with refractory filler.
Heating unit tool in the utility model has the dimensions, a plurality of heating units couple together and can surround being heated workpiece, electric heating element in heating unit is switched on power, the heat being distributed by electric heating element directly heats being heated workpiece, when the temperature that is heated workpiece reaches a certain particular value, its magnitude of interference has met interference matching requirements, now by making electric heating element deenergization, remove the heating unit that is heated workpiece periphery can stop heating.This kind of mode of heating not only can be increased work efficiency, and reduces waste of material and energy resource consumption, and broken through the restriction that is heated workpiece size and shape.The utility model is simple to operate, flexible, economical, save time, and is particularly useful for cylindrical work as the heating operation of axle sleeve etc.
Accompanying drawing explanation
Fig. 1 is the structural representation of heating unit in the utility model.
Fig. 2 is use view of the present utility model.
Embodiment
As depicted in figs. 1 and 2, the utility model is by some heating units by sequentially interconnecting regular or irregular exterior walls such as being assembled into annular or rectangle, and formed exterior wall will be heated workpiece 11 and tightly surround.
Each heating unit includes a substrate 6, and substrate 6 tools have the dimensions, for example, can be 200mm * 100mm.Substrate 6 can be nonmetallic cambered plate, can be also the metallic plate of being bent into arc face.
One row is respectively set in substrate 6 Ban Mian top and bottom and stands on substrate 6 Ban Mian end pillars 1, to be heated the end pillar 1 of workpiece 11, upper and lower relative up and down for supporting for end pillar 1.Between the space of end pillar 1, be connected to respectively the some ends stationary pipes 2 parallel with the plate face of substrate 6, in Liang Ge opposing upper and lower end stationary pipes 2, be connected with an electric heating element 5, electric heating element 5 can be resistance wire or electrical bar etc.
The present embodiment is provided with a row at the plate face middle part of substrate 6 and stands on substrate 6 Ban Mianbingyu end pillar 1 middle bilge cod 3 opposing upper and lower, between the space of middle bilge cod 3, be connected to the some middle parts stationary pipes 4 parallel with the plate face of substrate 6, electric heating element 5 passes from middle part stationary pipes 4.Bilge cod and many rows middle part stationary pipes in many rows can also be set in other embodiment.
Between end stationary pipes 2 and substrate 6 plate faces and between middle part stationary pipes 4 and substrate 6 plate faces, be provided with refractory filler 8.
In the edge of substrate 6, being provided with power interface 7(divides positive and negative electrode two interfaces), electric heating element 5 is connected with extraneous power supply by power interface 7.Electric heating element 5 on same heating unit is connected mutually, and the electric heating element 5 between different heating unit is connected in parallel to each other.Certainly, electric heating element can also be set in other embodiment and there is the connection in series-parallel relation that is different from this.
