Abstract
The utility model discloses a steel cylinder jacket semi-finished product for an internal combustion engine, comprising a pipe body, a baffle ring and a closing hole. The steel cylinder jacket semi-finished product has the structure that one end of the pipe body is processed to be the closing hole, through which the pipe body can be conveniently molded by stretching on a special film tool, and the baffle ring which is convenient for stretching a steel pipe to be thin is welded closely to the closing hole inside the pipe body. The baffle ring can bear high drawing force of the special film tool so as to lead the shorter thick wall pipe to be stretched into the thin wall pipe needed by the semi-finished product; and furthermore, a plurality of reprocessed steel cylinder jackets can be obtained by cutting off for once, so that the defect that most material can be wasted by molding a steel plate and turning molding the thick wall pipe can be overcome, processing with chip can be changed to be clean processing without chip, the effective utilization rate of the material and the quality of the finished production can be improved, the production cost is reduced, higher economic benefit is obtained by enterprises, and simultaneously a great deal of resource and energy can be saved for the country.
Description
One, technical field
The utility model relates to a kind of internal-combustion engine steel cylinder liner semi-finished product.
Two, background technique
Before the utility model proposes, the internal-combustion engine that people produce steel cylinder liner semi-finished product, structure is cylindric.Its half-finished acquisition of structures shape is a kind of to be that to adopt steel plate be raw material through blanking, stretching, cut-out moulding, once can only stretched semi-finished product, and the material effective rate of utilization only is 25%, 20 yuan/part of cost; The another kind of method that obtains is directly repeatedly car, the boring machine shaping of adopting more than 3.5 millimeters of seamless steel pipe, and the material effective rate of utilization only is 28.5%, and cost can only drop to 15 yuan/part.
Three, summary of the invention
In order to solve the deficiencies in the prior art, the purpose of this utility model provides a kind of internal-combustion engine steel cylinder liner semi-finished product, and can make the material effective rate of utilization only is 73.6%, and cost drops to 7 yuan/part.
Realize that the technological scheme that the purpose of this utility model adopts is: these steel cylinder liner semi-finished product are made of body, baffle ring and closing in; One end of body is processed into the closing in of being convenient to drawing and forming on special-purpose film tool, and closing in place of body inner close fitting is welded with the baffle ring of being convenient to the steel pipe tension-thining, and the baffle ring bearing thrust stretches steel pipe on special-purpose film tool becomes internal-combustion engine with steel cylinder liner semi-finished product.
The beneficial effects of the utility model are: close up and baffle ring because the end of body is provided with, baffle ring can sustain very big tensile force makes short thick walled tube be drawn into the long required thickness of thin-walled semi-finished product, once can obtain a plurality of reprocessed steel cylinder liner through cutting off, overcome the most of material that slatterns with steel plate forming and thick walled tube turning moulding, make bits processing become the chipless machining of cleaning, improved the quality of material effective rate of utilization and finished product, reduced cost of production, saved a large amount of resources and the energy for country when obtaining high economic benefit for enterprise.
Four, description of drawings
Fig. 1 is the utility model internal-combustion engine steel cylinder liner semi-finished product sectional structure chart.
Five, embodiment
In the accompanying drawings, the utility model internal-combustion engine is made of body, baffle ring and closing in steel cylinder liner semi-finished product; One end of body 3 has the closing in 1 of being processed into, and the effect one of closing in 1 is to be convenient to put in the special-purpose film tool, and the 2nd, make baffle ring 2 can bear bigger power; Body 3 inner close fittings 1 place that closes up is welded with the baffle ring 2 of being convenient to the steel pipe tension-thining, can bear bigger power by baffle ring 2 when the stretching steel pipe, can obtain steel cylinder liner semi-finished product the steel pipe drawing and forming on special-purpose film tool.Use structure of the present utility model and can make short thick walled tube be drawn into long thin walled tube, cut this thin walled tube and can obtain a plurality of required semi-finished product.
Embodiment one: selecting diameter is 108 millimeters, and length is 6000 millimeters.1 of the steel pipe that wall thickness is 3.5 millimeters, after the closing in of one end, at the 1 inboard welding baffle ring 2 that closes up, through after the intermediate treatment, be drawn into the body 3 of 1.35 millimeters wall thickness, both can obtain steel cylinder liner semi-finished product described in the utility model, cut off the steel cylinder liner that thin walled tube can be made into 77 needs reprocessing.3 borings of 1.35 millimeters bodys, mill are processed into the cylinder sleeve of 1.00 millimeters wall thickness.Through its material effective rate of utilization of COMPREHENSIVE CALCULATING is 73.6%, and cost drops to 7 yuan/part.
