Embodiment 1

[0021] Such as figure 1 As shown, a combined special-shaped casting pipe in this embodiment is composed of an adhesive 1, an adhesive 3 and a straight pipe 5. The adhesive 1 is cast by sand casting, and its adhesive fit Surface 2 is processed by machining to meet the requirements of bonding accuracy and smoothness; straight pipe 5 is made by centrifugal casting, and its bonding surface 4 is processed by machining to meet the requirements of bonding accuracy and smoothness. The joint surface 4 and the adhesive mating surface 2 of the adhesive member 1 are bonded with an adhesive 3 so that the straight pipe 5 and the adhesive member 1 are integrated.

[0022] The outer diameter of the adhesive mating surface 2 of the adhesive member 1 is 0.5-1mm smaller than the inner diameter of the adhesive surface 4 of the straight pipe 5, and the taper of the adhesive mating surface 2 of the adhesive member 1 is 3°. The taper of the bonding surface 4 of the straight pipe 5 is the same as th...

Embodiment 2

[0032] Such as figure 1 As shown, a combined special-shaped casting pipe in this embodiment is composed of an adhesive 1, an adhesive 3 and a straight pipe 5. The adhesive 1 is cast by sand casting, and its adhesive fit Surface 2 is processed by machining to meet the requirements of bonding accuracy and smoothness; straight pipe 5 is made by centrifugal casting, and its bonding surface 4 is processed by machining to meet the requirements of bonding accuracy and smoothness. The joint surface 4 and the adhesive mating surface 2 of the adhesive member 1 are bonded with an adhesive 3 so that the straight pipe 5 and the adhesive member 1 are integrated.

[0033] The outer diameter of the adhesive mating surface 2 of the adhesive member 1 is 0.5-1mm smaller than the inner diameter of the adhesive surface 4 of the straight pipe 5, and the taper of the adhesive mating surface 2 of the adhesive member 1 is 3°. The taper of the bonding surface 4 of the straight pipe 5 is the same as th...

Embodiment 3

[0043] Such as figure 1 As shown, a combined special-shaped casting pipe in this embodiment is composed of an adhesive 1, an adhesive 3 and a straight pipe 5. The adhesive 1 is cast by sand casting, and its adhesive fit Surface 2 is processed by machining to meet the requirements of bonding accuracy and smoothness; straight pipe 5 is made by centrifugal casting, and its bonding surface 4 is processed by machining to meet the requirements of bonding accuracy and smoothness. The joint surface 4 and the adhesive mating surface 2 of the adhesive member 1 are bonded with an adhesive 3 so that the straight pipe 5 and the adhesive member 1 are integrated.

[0044] The outer diameter of the adhesive mating surface 2 of the adhesive member 1 is 0.5-1mm smaller than the inner diameter of the adhesive surface 4 of the straight pipe 5, and the taper of the adhesive mating surface 2 of the adhesive member 1 is 3°. The taper of the bonding surface 4 of the straight pipe 5 is the same as th...

Abstract

The invention relates to a combined special-shaped cast pipe and a production method thereof, and belongs to a special-shaped centrifugation cast iron pipe and a production method thereof. The technical problems of low precision, low efficiency, high comprehensive price and poor outer surface roughness degree of the existing special-shaped pipe can be mainly solved. The combined special-shaped cast pipe is characterized in that the combined special-shaped cast pipe consists of a bonding part, a bonding agent and a straight pipe, wherein the bonding part is cast and shaped by a sand casting method; the straight pipe is cast and made through centrifugation; the bonding surface of the straight pipe and the bonding matching surface of the bonding part are bonded by bonding agents so that the straight pipe and the bonding parts are connected into a whole. The production method comprises the following steps of a, performing machine processing on the bonding matched surface of the bonding part; b, performing machine processing on the bonding surface of the straight pipe; c, preparing the bonding agents; d, bonding the bonding part and the straight pipe; e, drying the cast pipe.

Description

technical field [0001] The invention relates to a combined special-shaped casting pipe and a production method thereof, belonging to a special-shaped centrifugal cast iron pipe and a production method thereof. Background technique [0002] Traditional centrifugal casting can only make centrifugal straight pipes or centrifugal single-socket pipes, and cannot make special-shaped centrifugal cast iron pipes. Existing special-shaped pipes can only be completed by traditional sand casting, but these products all have a common feature: they are all cast by sand casting, the precision is difficult to reach the precision of centrifugal casting, and the efficiency of artificial molding is low. Higher, poor surface roughness inside and outside, difficult post-processing, it is difficult to meet the requirements of European standards. Therefore, the existing special-shaped tubes have the disadvantages of low precision, low efficiency, high comprehensive price and poor surface roughnes...
