Description
Technical field
The invention belongs to metallurgy industry cast steel plate mold casting technical field, be specifically related to a kind of high request machinery size adjustment mechanism in the die casting production of cast steel slab.
Background technology
Machinery is produced the most frequently used following two kinds of methods that have with cast steel plate at present:
The one, traditional sand mold Molding Casting production technology, this casting method is produced the cast steel slab, exist production efficiency low, workman's working condition is abominable, the high pollution of cost high energy consumption is heavy, the allowance that sand mold casts out is big, and lumber recovery is low, and the cast steel slab of producing is prone to defectives such as center porosity, shrinkage cavity, pore, burning into sand.
The 2nd, casting blank of continuous casting machine, it is strand method commonly used at present, the conticaster corollary equipment is many, mechanism's complexity, investment is big, surpasses the above cast steel plate of 320mm and realizes having only the conticaster of German western mark/De Make company to realize in the world at present than difficult with continuous casting, domestic new steel 420mm special heavy plate continuous casting line also is that plan prepare to be introduced external drawing improved project at present in the middle of project verification is prepared, and does not also have successful case.And there is a lot of internal soundness problems in strand, and defectives such as the shrinkage cavity of the thick more appearance of slab, serious loose, bulging crackle are heavy more.
99113068.5,03211226.2,201010105759.8,200710010868X etc. recent years, the water-cooled die casting production technology develops to some extent, as Chinese patent:, its advantage is that feeding is abundant, does not have shrinkage cavity, loose, forms fine and close, the production efficiency height, investment is little.Shortcoming is the die cavity relative fixed, and size be difficult for to be adjusted, and it is uncontrollable to solidify cooling procedure.Also do not produce the application precedent of big machinery simultaneously with cast steel plate.
Summary of the invention
The objective of the invention is in order to overcome above shortcoming, and during a kind of cast steel cut deal blank die casting that proposes produces, the device that the steel billet cavity dimension is adjustable.
The present invention is achieved by the following technical solutions:
The die casting size adjustable device of cast steel slab mainly comprises by left and right limit mould and main mould, leads the cast steel slab die cavity that attached mould is formed, and its improvement is that left and right limit mould and main attached mould are connected with hydraulic telescopic device respectively; Main mould is fixed on the body girder, and main attached mould is fixed on the girder by main mould propulsion cylinder; Be provided with a cocainine post adjustment mechanism between the girder; Cast steel slab die cavity top is provided with adjustable for height built-in heat-insulating shield.
Hydraulic telescopic device usually of the present invention comprises left and right limit mould propulsion cylinder and main attached mould adjusting cylinder and the main mould propulsion cylinder that is connected with hydraulic system.
Hydraulic telescopic device is regulated the width that cylinder is regulated the cast steel slab by the left and right limit mould propulsion cylinder and the main attached mould that are connected with hydraulic system; Utilize a cocainine bar to regulate the thickness of cast steel slab; Utilize the built-in heat-insulating shield of steel billet die cavity upper suspension to carry out the adjusting of cast steel slab height in the position of die cavity.
The attached mould of the master of apparatus of the present invention is fixed on the girder by main mould propulsion cylinder, and is provided with bearing pin and the pin-and-hole that is used to locate.
The present invention also is connected with the discharge control system, realizes that by control discharge slab solidifies cooling control; Can also adopt argon shield and covering slag protection placing realization inside and surface quality good.
Apparatus of the present invention, the steel billet cavity dimension is regulated within the specific limits, and it is controlled that slab solidifies cooling; Main attached mould is fixed on the girder by main mould propulsion cylinder, can realize gently depressing technology with the solidification shrinkage follow-up, is convenient to the cast and the demoulding of cast steel slab, shortened the production cycle, reduce production cost, realized cleaner production, reduced pollution simultaneously, meet country and subtract the demand that can reduce discharging, the cast steel slab feeding of producing is abundant, does not have shrinkage cavity, loose, dense structure, surface quality is good, and combination property is excellent.
Description of drawings:
Accompanying drawing 1 is the plan structure schematic diagram of embodiment of the invention water-cooled die casting size adjustment mechanism.
Among the figure, 1-left side mould; The attached mould of 2-master; 3-the right mould; 4-master's mould; 5-cast steel slab die cavity; 6-body girder; 7-left side mould propulsion cylinder; 8-the right mould propulsion cylinder; The attached mould of 9-master is regulated cylinder; 10-regulates screw mandrel for one group; 11-master's mould propulsion cylinder connecting pin pin hole; 12-master's mould propulsion cylinder; The built-in heat-insulating shield of 13-.
The specific embodiment
The present invention is further illustrated below in conjunction with embodiment and accompanying drawing.
Embodiment: present embodiment as shown in Figure 1, mainly comprise the cast steel slab die cavity of forming by left side mould, the right mould 3 and main mould 4, main attached mould 25, be connected with hydraulic telescopic device respectively on the left side mould 1, the right mould 4 and the main attached mould 2, the left side mould propulsion cylinder 7 that promptly is connected with hydraulic system, the right mould propulsion cylinder 8 and main attached mould are regulated cylinder 9; Main mould 4 is fixed on the body girder 6, and main attached mould 2 is fixed on the girder 6 by main mould propulsion cylinder 12, is provided with one group between the girder 6 and regulates screw mandrel 10; Cast steel slab die cavity 5 tops also are provided with adjustable for height built-in heat-insulating shield 13; Connect main mould propulsion cylinder 12 on the main attached mould 2 and be provided with the bearing pin pin-and-hole 11 that is used to locate.
Apparatus of the present invention broaden if need to regulate slab when producing the cast steel slab, then earlier the bearing pin that connects main mould propulsion cylinder 12 on the main attached mould 2 are withdrawed from from pin-and-hole, and main attached mould is regulated cylinder 9 elongations, 7 withdrawals of left side mould propulsion cylinder.
