Abstract
An extrusion die heating device for an extruding machine relates to an extrusion die of the extruding machine. The extrusion die heating device is capable of resolving the problem that temperature change of the extrusion die of the extruding machine can affect service life of the extrusion die and quality of profiles. The extrusion die heating device comprises a movable die seat and a fixing frame of the extrusion die and is characterized in that a heating device is composed of a temperature thermocouple installed on the movable die seat, an insertion type resistor heater, a quick inserted-type connector assembly arranged between the movable die seat and the fixing frame and a control circuit. The extrusion die heating device is applied to the extrusion die of the extruding machine and has the advantages of being simple in structure, reliable in control, good in quality of extruded products and long in service life of the extrusion die.
Description
Technical field
The utility model relates to extruder, particularly the extrusion die on the mobile die holder of extruder.
Background technology
Guaranteeing aspect the quality of extrudate, as long as traditional experience is thought the precision that has guaranteed extruder and extrusion die, just can produce qualified section bar.Therefore, present extruder is not considered the variations in temperature of extrusion die basically.And actual conditions are in the process of extruding beginning and extruding, and the Temperature Distribution of extrusion die can change, and must influence the life-span of extrusion die and the quality of section bar.The extrusion die variation in temperature distribution is helpless for the control system of extruder.
Summary of the invention
The purpose of the utility model is to overcome the shortcoming of prior art, and a kind of extrusion die heater of extruder is provided, and solves the variations in temperature of extruder extrusion die, influences the life-span of extrusion die and the problem of section quality.
The task of the utility model is to adopt following measure to realize:
A kind of extrusion die heater of extruder; Comprise: the mobile die holder and the fixed mount of extrusion die is characterized in that: said heater is made up of the rapid plug-in adapter assembly and the control circuit that are installed in temperature thermocouple on the said mobile die holder, plug-in type resistance heater, be arranged between said mobile die holder and the said fixed mount.
Said adapter assembly is made up of movable contact, stationary contact, control line outlet, power line outlet, control contact, earthing contact, zero line contact and firewire contact, and said movable contact is installed on the said mobile die holder, and said stationary contact is installed on the said fixed mount.
Said control circuit comprises control contactor and the automatic switch that is loaded in the electrical control cabinet.
The utility model compared with prior art becomes possibility because said heater for the extrusion die accuracy control over temperature provides condition, makes the simulation isothermal of extruder push.The utlity model has simple in structurely, control is reliable, and the quality of extruded product is good, the advantage of extrusion die high life.

Fig. 1 is the extrusion die heater and the location drawing of rapid plug-in adapter assembly on extruder;
Fig. 2 is an extrusion die heater installation diagram;
Fig. 3 is the sketch map of rapid plug-in adapter assembly;
Fig. 4 is the fixedly sketch map of rapid plug-in adapter assembly sound contact;
Fig. 5 is an extrusion die heater electrical schematic diagram.
The utility model is further described through embodiment below in conjunction with accompanying drawing.
The specific embodiment
Like Fig. 1,2,3,4, shown in 5; A kind of extrusion die heater of extruder; Comprise: mobile die holder of extrusion die 1 and fixed mount 6, said heater is made up of the rapid plug-in adapter assembly 2 and the control circuit that are installed in temperature thermocouple 4 on the said mobile die holder 1, plug-in type resistance heater 5, be arranged between said mobile die holder 1 and the said fixed mount 6.
Said adapter assembly 2 is made up of movable contact 2-1, stationary contact 2-2, control line outlet 2-3, power line outlet 2-4, control contact 2-5, earthing contact 2-6, zero line contact 2-7 and firewire contact 2-8; Said movable contact 2-1 is installed on the said mobile die holder 1, and said stationary contact 2-2 is installed on the said fixed mount 6.
Said control circuit comprises the control contactor 7 and automatic switch 8 that is loaded in the electrical control cabinet.
The utility model is to utilize the temperature of 5 pairs of compression tools 3 of plug-in type electromagnetic heater to add thermal control, makes the extrusion die can be owing to the acute variation of the temperature difference, and produces big thermal (temperature difference) stress.The temperature of extrusion die remains on to fixed temperature before the extruding beginning, and the Temperature Distribution of extrusion die is reached unanimity.The power connection of heater is a rapid plug-in adapter assembly 2, does not influence the quick replacing of extrusion die.Owing to move the motion of die holder 1 power line and control line can't be drawn; And rapid plug-in adapter assembly 2 is mobile jacks of a power supply and control line; Power line and control line broke off when mobile die holder 1 was shifted out, and power line and control line are connected during immigration.
The installation and the use of the utility model are following:
1, at first extruder is moved the movable contact 2-1 of temperature thermocouple 4 on the die holder 1, plug-in type resistance heater 5, rapid plug-in adapter assembly 2, the stationary contact 2-2 of the rapid plug-in adapter assembly 2 on the fixed mount 6 and control line and power line install.
2, die holder 1 is moved in first preheating before extruding, and when being preheated to design temperature, the compression tool 3 that will in preheating furnace, heat is lifted on and moves in the die holder 1, prepares extruding.
3, when recipient leans on extrusion die fully, because the temperature difference of recipient and mobile die holder, under heat conducting effect; Temperature reaches unanimity very soon, and the recipient liner difference of temperature up and down also must be transmitted on the extrusion die, causes the temperature up and down of extrusion die also different; Temperature of lower is low, and upper temp is high, certainly will influence the quality of extrudate; For this reason, need add thermal control to the bottom of extrusion die, to reduce the extrusion die temperature difference up and down through the utility model; So that the metallographic structure of extrudate reaches unanimity, be beneficial to the subsequent heat treatment of extrudate.
