Abstract
The invention discloses a device for casting a compound hammerhead and a method for casting the same, wherein the device comprises a casting box consisting of an upper mould plate and a lower mould plate through compounding, two sides of the casting box are provided with box clamps, a die cavity of which the shape is fit close with that of the hammerhead is arranged in the casting box, the top end of the die cavity is provided with a riser head, the left side and the right side of the die cavity are provided with a pouring channel I and a pouring channel II respectively, and opening parts of the other ends of the pouring channel I and the pouring channel II are arranged on the top of the casting box. The method comprises the following steps: pouring molten metal I into the pouring channel I so that the molten metal I flows into the bottom of the die cavity under the action of gravity; and when the molten metal I begins to pre-harden, pouring molten metal II into the pouring channel II so that the molten metal II flows onto the molten metal I in the die cavity under the action of gravity, and then adding a heat-generating agent into the die cavity so that the molten metal I and the molten metal II are fused integrally to form the hammerhead. The method uses two metals to cast the hammerhead through thermal compound, so on the basis of keeping the original toughness, the wearing resistance of the hammerhead is increased, the crack resistance of a hammer handle is reliable, the production cost is greatly reduced, the service life of the hammerhead is prolonged, and the mechanical maintenance rate is low.
Description
Technical field
The present invention relates to a kind of composite hammer head casting device and composite hammer head casting method.
Background technology
The application of tup in various disintegrating machines is very extensive, is the main wearing piece of disintegrating machine, and the cost of tup and its wearability are directly connected to the production cost that disintegrating machine uses producer.The casting method of tradition tup all be that single metal liquid of planting is once cast and formed, and not only wears no resistance, and hammer handle cracking resistance poor reliability is produced the cost height of this kind tup, and this tup incompatibility uses on disintegrating machine.
Existing composite hammer head, so-called composite hammer head is promptly for being connected to tup by multiple metal material with machinery assembling, bonding assembling or metallurgical mode such as compound, the tup poor toughness of machinery assembling, and impact resistance is not high, the adhesive surface bad mechanical property of bonding assembling tup, fracture easily in the use.To need in the device that has tup now to increase extra die cavity in order producing, increased the cost of device, and the cast structure of device inside to be also unreasonable in conjunction with above-mentioned casting method.Chinese patent CN91218917.7 discloses a kind of hammer mill bimetallic composite hammer head, it is made up of two parts up and down, adopt the notch mode to connect, and reinforce with binding agent, but this kind tup essence still is the machinery assembling, and impact resistance is low, and the notch structure is under external impacts, very easily fracture causes accidents such as the tup fragment flies out.The frequency of utilization height of tup, the tup working portion is cracked just can not to be used, and frequent replacing tup causes the production cost of producer to improve, and production efficiency reduces.
Summary of the invention
Problem to be solved by this invention is exactly that shortcoming at prior art provides that a kind of casting technique is simple, the composite hammer head casting device and the composite hammer head casting method of wearability and strong shock resistance.
In order to solve the problems of the technologies described above, the present invention has at first proposed a kind of composite hammer head casting device, described device comprises the molding box that is composited by bolster, the molding box both sides are provided with clamp, it is characterized in that: be provided with the die cavity that coincide with the tup profile in the molding box, the die cavity top is provided with rising head, the die cavity left and right sides is provided with running channel I and running channel II respectively, described running channel I connects the bottom of die cavity one side, running channel II connects the top of die cavity opposite side, and the other end opening part of running channel I and running channel II is arranged on the molding box top.
Method by said apparatus casting composite hammer head, comprise the steps: molten metal I is poured in the running channel I, molten metal I flows into cavity bottom under the effect of gravity, when treating that molten metal I begins initial set, molten metal II is poured in the running channel II, molten metal II flows under the effect of gravity on the molten metal I in the die cavity, adds exothermic mixture again, cooling back molten metal I and molten metal II combine together, and form tup.
Further, the raw material of described molten metal I is the ZG35 steel, reduces production costs; The raw material of molten metal II is 2 wear-resistant white cast KMTBCr20MoNi, and it is anti-wear to increase tup.
The present invention has following advantage: adopt the hot composite casting tup of bimetallic, keeping on the original toughness of the tup basis, the wearability of tup increases, and the hammer handle crack resistance is reliable, and production cost reduces greatly, tup lengthening in service life, and the flight-line maintenance rate is low; Apparatus of the present invention are simple in structure, and cost is low; Casting method is simple.
Description of drawings
The invention will be further described below in conjunction with accompanying drawing:
Fig. 1 is the structural representation of composite hammer head casting device of the present invention.
The specific embodiment
The structural representation of composite hammer head casting device of the present invention as shown in Figure 1, comprise the molding box 3 that is composited by bolster, molding box 3 both sides are provided with clamp 32, be provided with the die cavity 31 that coincide with the tup profile in the molding box 3, die cavity 31 tops are provided with rising head 35, die cavity 31 left and right sides are provided with running channel I 33 and running channel II 34 respectively, running channel I 33 connects the bottom of die cavity 31 1 sides, running channel II 34 connects the top of die cavity 31 opposite sides, and the other end opening part of running channel I 33 and running channel II 34 is arranged on molding box 3 tops.
The casting method of above-mentioned composite hammer head is as follows: molten metal I is poured in the running channel I 33, molten metal I flows into die cavity 31 bottoms under the effect of gravity, when treating that molten metal I begins initial set, again molten metal II is poured in the running channel II 34, molten metal II flows under the effect of gravity on the molten metal I in the die cavity 31, add exothermic mixture, cooling back molten metal I and molten metal II combine together, and form tup.
Provide a preferred embodiment of the casting method of composite hammer head of the present invention below: the ZG35 steel molten steel that takes by weighing 103 kilograms with casting ladle is poured in the running channel I 33 as molten metal I, ZG35 steel molten steel flows under the influence of gravity into die cavity 31 bottoms, and begin to solidify, finish the casting of hammer handle part; The white cast-iron KMTBCr20MoNi iron liquid that takes by weighing 90 kilograms is simultaneously poured in the running channel II 34 as molten metal II, white cast-iron KMTBCr20MoNi iron liquid flows under the effect of gravity on the ZG35 steel molten steel of initial set in the die cavity 31, add exothermic mixture, treat foundry goods in die cavity 31, be incubated be cooled to 500 the degree below, open die cavity 31, treat that again foundry goods is cooled to room temperature after, knock-off waters road junction and rising head, removal face sand is finished the casting production of tup.
