Description
Technical field
The present invention relates to the HTFX field, specifically is a kind of blackout stove.
Background technology
The blackout stove is the powder metallurgy workpiece to be heat-treated make the workpiece surface blackout form the body of heater of resist; It comprises bell, furnace wall and base; Bell, furnace wall and base are enclosed the furnace chamber that is used for ccontaining workpiece to be heated, and bell is hinged on the top of furnace wall, and bell is provided with the hole that a plurality of confession screws pass; The furnace wall top be provided with bell on hole threaded hole one to one, the bell lower surface is fixed with sealing-ring.In the time of need closing the bell heat treated part, bell is covered in the opening of furnace chamber after, with passing the hole of bell and being tightened on the screw of threaded hole of furnace wall that bell is locked; In the time of need opening bell and take, put workpiece, then unclamp screw and raise bell again.
Because the bell of the blackout stove of prior art is that manual folding relies on screw lock again, so there is following defective: perform fighting or close bell, all need manually screw or unclamp screw at every turn; Process bothers, wastes time and energy, and more crucial is; Bell is to rely on screw lock, and its sealing effectiveness is very poor, and this has just caused the pressure in the furnace chamber to improve; Generally can only reach about 0.3bar; Than heat treated workpiece under the subatmospheric, the blackout layer thickness is less and in uneven thickness, and the blackout thermal effectiveness is undesirable.
And in order to strengthen the gaseous exchange in the furnace chamber; This blackout stove also comprises wind wheel and is fixed on the vertical phonomoter of bell; Be penetrated with through hole on the bell; The motor output shaft via through holes passes bell and output shaft lower end and wind wheel and fixes, and the wind wheel that motor output shaft drives in the furnace chamber rotates, thereby strengthens the steam convection current.Though be provided with wear ring between motor output shaft and the bell through hole; But relatively rotate owing to exist between the output shaft of phonomoter and the wear ring, promptly sealing is the rotating ring sealing, so sealing effectiveness is undesirable; Make the furnace chamber internal pressure to improve equally, workpiece blackout thermal effectiveness is poor.
Summary of the invention
The technical problem that the present invention will solve is, provides a kind of and open, lock process convenient quick and can improve the blackout stove of furnace chamber internal gas pressure.
Technical solution of the present invention is, a kind of blackout stove is provided, and it comprises bell, furnace wall and base; Bell, furnace wall and base are enclosed furnace chamber; It also comprises a lift cylinder and a rocking arm, and the piston rod of lift cylinder is connected with the outer end of rocking arm, and the inner and the bell of rocking arm are fixed; The cylinder wall and the furnace wall of lift cylinder are fixed; The inwall of furnace wall be provided with a level to annular recesses, be provided with a self-locking ring that can circumferentially rotate along annular recesses in the annular recesses, self-locking ring is provided with second cylinder that is used to rotate self-locking ring; The outer circumference surface of bell is provided with the radially projection of evagination, and the inner peripheral surface of self-locking ring is provided with the lock dog with the projection rotational lock that is used for of convex radially; The lower end of the shell of phonomoter is a flanged end, and the top of bell is fixed with ring flange, the flanged end of phonomoter and the ring flange of bell is fixed and be provided with wear ring between the two.
The process of the bell of this blackout stove locking does, the piston rod of decline lift cylinder drives bell through rocking arm and descends, treat bell descend put in place after, drive second cylinder, the forward rotation self-locking ring makes the lock dog of self-locking ring and the projection of bell lock; The process that the bell of this blackout stove is opened does; Reverse drive second cylinder makes self-locking ring rotate and resets, and then makes the lock dog of self-locking ring and the projection of bell break away from; Rotation along with self-locking ring; After the lock dog of self-locking ring was not positioned at the top of projection of bell fully, the piston rod of rising lift cylinder drove bell and rises.
The blackout stove that adopts above structure compared with prior art has the following advantages:
Because this blackout stove is to rely on the lift cylinder and second cylinder to lock or open bell fully, comparing manually screws unscrews screw, and the bell of blackout stove of the present invention is locked, opening procedure is more convenient; Time saving and energy saving; More crucial is that this blackout stove is to adopt the air cylinder driven self-locking ring, utilizes the lock dog of self-locking ring and the projection rotational lock of bell; So sealing effectiveness in the furnace chamber is better more firmly closely; And because the present invention is provided with wear ring between the ring flange of the flanged end of phonomoter and bell, flanged end and ring flange can not relatively rotate, i.e. the mode that the present invention seals with stationary ring has replaced the rotating ring sealing means of prior art, so stopping property is better; Reason owing to above two aspects; The present invention's stove better tightness of turning black; Thereby can bear bigger furnace chamber internal pressure, the force value in the furnace chamber of this blackout stove generally can reach about 1.5bar workpiece thermal treatment under higher gas pressure; The blackout layer thickness is big and thickness is even, and the blackout thermal effectiveness is desirable.
As improvement, the cylinder wall and the furnace wall of second cylinder are hinged, and the piston rod and the self-locking ring of second cylinder are fixed, and this mode of connection is simple in structure, and good reliability elongates or shortens the piston rod of second cylinder, the self-locking ring of rotation forward or backwards that just can be convenient and reliable.
As a further improvement, the multi-block projection along the outer circumferential surface of the lid bumps evenly distributed; locking blocks for multiple locking ring along the inner circumferential surface of the locking blocks evenly distributed; upper end of each of the bumps first slope, the lower end of each locking block with the first bevel with a lock for a second bevel, so bumping and lock blocks evenly distributed and correspondence, when the lid is locked force uniform, lock tight results are satisfactory, and, as driven by self-locking ring lock blocks along the circumferential direction of rotation of the self-locking ring, the first and second bevel bevel-by-step against each other uplifted, and gradually tighten the locking effect is solid and reliable.
As also improving, it also comprises the 3rd cylinder, and the piston rod top of lift cylinder is fixed with connecting rod, and the top of connecting rod and the outer end of rocking arm are hinged; Also be fixed with the ring plate that is positioned at the rocking arm below on the connecting rod, the cylinder wall and the ring plate of the 3rd cylinder are hinged, and the piston rod and the rocking arm of the 3rd cylinder are fixed; Like this, drive the 3rd cylinder, rocking arm can be along with the elongation of piston rod level to swing; Drive bell and make bell no longer be positioned at the top of furnace chamber to rotation around the connecting rod level, reverse drive the 3rd cylinder, rocking arm can be along with the retracted for clearance of piston rod; Again be positioned at the furnace chamber top, this structure ability automatic horizontal is convenient to people and is picked and placeed workpiece to bung.
