Abstract
The invention discloses a large-plane point feeding process for a saddle casting. A sand core saddle panel is adopted in the large-plane point feeding process. A sunken bolt machining surface is arranged on the saddle panel. Exothermic risers are formed in the bolt machining surface. The exothermic risers are adopted, so that the feeding efficiency is high, and the process yield of products is effectively increased. The process yield of saddles can reach up to 80%-90% and is increased by 10% compared with that of an existing level, and the production cost is effectively reduced.
Description
Technical field
The present invention relates to auto parts and components and accessory casting technology field, more particularly, relate to the large planar point feeding technology of saddle foundry goods.
Background technology
The internal stress of ironcasting is less than the internal stress of weldment, through the remnants of the ironcasting of Wetted constructures
Stress is then less, and the distortion produced in use procedure is thereafter also just little, and ironcasting inside is made up of ferrite and a large amount of graphite, loose due to graphite tip, causes residual stress very little.And the stress that weldment produces in welding process is very large, if carry out the process eliminating internal stress not in time, component will produce the consequence of cracking or distortion.Therefore, structurally, cast-in-block saddle has the advantage in performance than weldment saddle.But saddle foundry goods is comparatively large due to panel area, easily occurs shrinkage porosite phenomenon.
Summary of the invention
The present invention, for solving the deficiencies in the prior art, provides a kind of saddle foundry goods rational in infrastructure, that castability is excellent large planar point feeding technology, to solve saddle Shrinkage Porosity problem.
The technical solution adopted for the present invention to solve the technical problems is: the large planar point feeding technology of a kind of saddle foundry goods, comprises core saddle panel, and saddle panel has the bolt machined surface of sinking, and described bolt machined surface is provided with exothermic riser.
Described exothermic riser is four, lays respectively on the bolt mounting holes center line on bolt machined surface.
Described saddle adopts 400-18LT monoblock cast to obtain.
Compared with prior art, the invention has the beneficial effects as follows:
The present invention adopts exothermic riser, and feeding efficiency is high, effectively provides the product yield of product.Saddle product yield up to 80-90%, can improve 10% than existing level, effectively reduces production cost.
Accompanying drawing explanation
Fig. 1 is the dead head structure top view of the large planar point feeding technology of saddle foundry goods of the present invention.
Fig. 2 is the dead head structure side view of the large planar point feeding technology of saddle foundry goods of the present invention.
Detailed description of the invention
Be described below in detail embodiments of the invention, the example of described embodiment is shown in the drawings, and wherein same or similar label represents same or similar element or has element that is identical or similar functions from start to finish.Being exemplary below by the embodiment be described with reference to the drawings, only for explaining the present invention, and can not limitation of the present invention being interpreted as.
See Fig. 1-2, the invention provides the large planar point feeding technology of a kind of saddle foundry goods, comprise core saddle panel 1, saddle panel has the bolt machined surface 2 of sinking, described bolt machined surface is provided with exothermic riser 3.Exothermic riser 3 is four, lays respectively on the bolt mounting holes center line on bolt machined surface.Saddle adopts 400-18LT monoblock cast to obtain.
The present invention adopts a feeding exothermic riser, and neck is less, can directly be knocked out by rising head, because this position is bolt mounting holes center line, is the position of processing boring, namely eliminates rising head vestige, can exempt polishing operation after boring.
Do not need to arrange other rising heads again in the upper plane of saddle panel, upper surface quality can be improved.
Below openly specific embodiments of the invention are only; do not form limiting the scope of the invention; for general technical staff of the technical field of the invention; do not departing under general idea prerequisite of the present invention; according to technical solution of the present invention do without the need to through the change of creative work and replacement, all should drop within protection scope of the present invention.
