Abstract

The invention discloses a separated pouring truck of a centrifugal machine of which the key improvement is characterized by comprising two sets of pouring trucks which are arranged in parallel and have same structure, wherein one set of the pouring truck comprises an upper body, a lower body, a connection device of the upper body and the lower body, a running mechanism, a falling groove and a falling groove driving device, wherein the running mechanism is arranged on the bottom of the lower body, and the falling groove and the falling groove driving device are arranged on the top of the body. The separated pouring truck has the following advantages: two pouring trucks with same structure are arranged in parallel and are both provided with the independent driving devices, so that two pouring trucks can simultaneously operate and can independently operate; the upper body and the lower body are connected by a guide sleeve and a guide post; the relative positions of the guide sleeve and the guide post are changed to adjust the height of a launder to ensure the centre line of the launder is reasonable relatively to the horizontal line angle; a hydraulic motor drives the launder to rotate to prevent the phenomenon that the production process is easy to clamp, thus effectively improving the manufacturability of the pouring process of the water cooling metal nodular cast iron pipe and improving production efficiency.

Description

Separated pouring truck of centrifugal machine

Technical field

The present invention relates to a kind of water-cooled metal mould ductile iron pipe production equipment, particularly a kind of separated pouring truck of centrifugal machine.

Background technology

Existing water-cooled metal mould ductile iron pipe centrifuge pouring truck comprises that lower body, upper body, driving oil cylinder, left low water support, right low water supports, and left low water supports, right low water is supported and fixed on the upper body, drives the chute support through tooth bar, oil cylinder and floating bearing and carries out 180 ° of back and forth rotations; Upper body is installed on the lower body through rotating shaft; Lower body and cast are provided with the walking mechanism that the hydraulic cylinder that drives its operation and slide rail and pulley are formed between the framework, parallelly on the upper body are provided with left low water and support with right low water and support, and specifically can only adjust the angle between low water center line and the horizontal line through the angle of adjusting between upper body and the lower body in the production process; Can not directly adjust the low water height; Influencing production technology property, is exactly that left low water and right low water all are installed on the upper body more in addition, if there is a low water to break down; Overhaul with regard to shutting down; Directly influence production efficiency, also having a problem is the structure more complicated that low water supports, and environment for use is had relatively high expectations; The phenomenon that occurs clamping stagnation or male part easy abrasion easily, also efficient and casting quality are poured into a mould in influence to a certain extent.

Summary of the invention

The present invention provides a kind of can effectively improve water-cooled metal mould ductile iron pipe casting process manufacturability, improves the separated pouring truck of centrifugal machine of production and processing efficient.

For solving the problems of the technologies described above, the technical scheme that the present invention adopted is: separated pouring truck of centrifugal machine, and its key improvements is: comprise the identical pouring truck of structure that two covers are set up in parallel; Wherein a cover pouring truck comprises upper body, lower body, upper body and lower body jockey, is arranged on the running mechanism of lower body bottom and is arranged on the low water and the low water drive unit at upper body top; Said running mechanism comprises the pulley that is arranged on the lower body bottom, the hydraulic cylinder that is arranged on walking rails that cooperates with pulley and the slide rail on the cast framework and is located at the lower body bottom, and hydraulic cylinder is hinged on the cast framework, push rod and lower body bottom-hinged; Said jockey comprises the guide shaft guide pin bushing combination of being located between upper body and the lower body; Said low water drive unit is the hydraulic motor that is fixedly installed on the upper body top, and hydraulic motor output shaft is fixedly connected with connector on being fixed on the low water bottom surface.

Adopt the beneficial effect that technique scheme produced to be: to be set up in parallel two cast dollies that structure is identical; Two cast dollies are equipped with independent drive unit, so the operation simultaneously of two cast dollies also can the split operation, adopt guide pin bushing to be connected with guide pillar between upper body and the lower body; Chute is just adjusted through the relative position that changes guide pin bushing and guide pillar and is realized; Guarantee that the relative horizontal line angle of chute center line is more reasonable, the rotation of fluid motor-driven chute prevents the phenomenon of clamping stagnation generation easily in the production process; Effectively improve water-cooled metal mould ductile iron pipe casting process manufacturability, enhance productivity.

The specific embodiment

For making above-mentioned purpose of the present invention, characteristic and beneficial effect can be more obviously understandable, will combine the accompanying drawing and the specific embodiment in the embodiment of the invention below, and the technical scheme in the embodiment of the invention is carried out clear, intactly description.

Separated pouring truck of centrifugal machine as depicted in figs. 1 and 2, its key improvements is: comprise the identical pouring truck of structure that two covers are set up in parallel; Wherein a cover pouring truck comprises upper body 4, lower body 2, upper body 4 and lower body 2 jockeys, is arranged on the running mechanism of lower body 2 bottoms and is arranged on the low water 8 and the low water drive unit at upper body 4 tops; Said running mechanism comprises the pulley that is arranged on lower body 2 bottoms, is arranged on walking rails that cooperates with pulley 1 and slide rail 9 on the cast framework and the hydraulic cylinder 10 of being located at lower body 2 bottoms; Hydraulic cylinder 10 is hinged on the cast framework, push rod and lower body 2 bottom-hinged; Said jockey comprises the guide shaft guide pin bushing combination of being located between upper body 4 and the lower body 2; Said low water drive unit is the hydraulic motor 5 that is fixedly installed on upper body 4 tops, and hydraulic motor 5 output shafts 6 are fixedly connected with connector 12 on being fixed on low water 8 bottom surfaces.

Said guide shaft guide pin bushing combination comprises guide shaft 11 and guide pin bushing 3, and guide shaft 11 and guide pin bushing 3 tight fits are uniformly distributed with row's vertical spacing hole respectively on the outer wall of guide shaft 11 and guide pin bushing 3.

In concrete application process, two hydraulic cylinders that are installed in the lower body bottom of the cast dolly that is set up in parallel can link, also can transfer; Realization is installed in the interlock and the transfer of two low waters on the cast dolly, even one of them low water breaks down, the another one low water also can carry out operation separately; Need not shut down maintenance, enhance productivity, adopt the combination of guide shaft guide pin bushing to be provided with between upper body and the lower body; Can adjust the height of upper body according to the needs of cast; And low water is fixedly mounted on the upper body, so the height of low water changes with the variation of upper body height, realizes the adjustment of low water level height; And the rotation that is installed in the hydraulic motor at upper body top can drive the back and forth rotation of low water 180 degree, effectively improves separated pouring truck of centrifugal machine production technology property.
