Abstract
The present invention relates to a kind of weldable wearproof composite hammer head disappearance mould production method. Comprise the following steps: 1., first to manufacture carbon steel part, make the EPS block of carbon steel part by the production method of disappearance mould, utilize disappearance mould production method cast carbon steel part; 2. the bonding surface Shot Blasting, by the carbon steel part poured into a mould and rich chromium cast iron part, polishing, remove scale, the greasy dirt dirt on surface; Low-temperature heat, brush coating on bonding surface, moisture forms layer protecting film after evaporating, it is possible to prevent bonding surface to be oxidized; 3., cast, the EPS block of carbon steel part and rich chromium cast iron part and reinforcement process hole place that brushes coating are glued, the rising head EPS on bonding top simultaneously, brush diatomite coating, after dry, at bonding surface place, sticky ingate EPS block and cross gate EPS block, utilize disappearance mould production method to pour into a mould. Its technique is simple, and the wear-resistant hammer head of production has weldability.
Description
Technical field
The present invention relates to a kind of disappearance mould production method, the particularly production method of a kind of weldable wearproof composite hammer head disappearance mould.
Background technology
Wear-resistant hammer head is used for the operating mode with impelling strength and wear resistance requirement, and the past often uses high mangaenese steel, and some occasion adopts ultra-high manganese steel now, to improve wear resistance and the work-ing life of tup. But composite wear-resistant hammerhead has the trend substituting high mangaenese steel gradually, composite hammer head mainly refers to high mangaenese steel and the compound of rich chromium cast iron two kinds of materials, mainly utilizing the impelling strength of high mangaenese steel and the wear resistance of rich chromium cast iron, composite hammer head has that impelling strength height, wear resistance are good, the feature of long service life. But complex process, and not there is weldability.
Summary of the invention
In order to overcome the shortcoming of prior art, the present invention provides a kind of weldable wearproof composite hammer head disappearance mould production method. Its technique is simple, has weldability.
The present invention solves the technical scheme that its technical problem takes: comprises the following steps: 1., first manufacture carbon steel part, makes the EPS block of carbon steel part by the production method of disappearance mould, utilizes disappearance mould production method cast carbon steel part; 2. the bonding surface Shot Blasting, by the carbon steel part poured into a mould and rich chromium cast iron part, polishing, remove scale, the greasy dirt dirt on surface; Low-temperature heat, brush coating on bonding surface, moisture forms layer protecting film after evaporating, it is possible to prevent bonding surface to be oxidized; 3., cast, the EPS block of carbon steel part and rich chromium cast iron part and reinforced hole place that brushes coating are glued, the rising head EPS on bonding top simultaneously, brush diatomite coating, after dry, at bonding surface place, sticky ingate EPS block and the cross gate EPS block having brushed coating, utilizes disappearance mould production method to pour into a mould.
Recombining process of the present invention is simple, and wear-resistant hammer head has weldability.

Embodiment
As shown in Figure 1-Figure 3, weldable wearproof composite hammer head is made up of carbon steel part 3 bi-material of the rich chromium cast iron part 1 on top and bottom, is bonding surface 2 between rich chromium cast iron part 1 and carbon steel part 3.
1. the present invention comprises the following steps:, first manufactures carbon steel part 3, makes the EPS block 4 of carbon steel part 3 by the production method of disappearance mould, as shown in Figure 4, Figure 5; Utilize disappearance mould production method cast carbon steel part 3; 2., by bonding surface 2 Shot Blasting of the carbon steel part 3 poured into a mould and rich chromium cast iron part 1, polishing, the dirts such as the scale on surface, greasy dirt are removed; Low-temperature heat, brush coating on bonding surface 2, moisture forms layer protecting film after evaporating, it is possible to prevent bonding surface to be oxidized; 3., cast, the EPS block 6,8 at carbon steel part 3 and rich chromium cast iron part 1 and reinforced hole 5 place that brushes coating are glued, the rising head EPS block 11 on bonding top simultaneously, as shown in Figure 6, Figure 7, brush diatomite coating, after oven dry, at bonding surface 2 place, sticky ingate EPS block 10 and cross gate EPS block 9, as shown in Figure 8, utilize disappearance mould production method to pour into a mould.
The EPS block 4 of described step carbon steel part 3 1. there is reinforcement process hole 5.
Described reinforcement process hole 5 has four.
Described step coating 2. is boric acid coating. Prevent the oxidation of bonding surface, simultaneously owing to fusing point is lower, it is possible to fusing in time rises in rising head 11.
Cavity 7 is had in the EPS block 6 of described step rich chromium cast iron part 1 3.. Decrease the consumption of EPS, it is possible to reduce the gas forming amount of EPS, it is to increase production capacity quality.
Described step ingate EPS block 10 3. is 1-8 degree with the angle of the bonding surface 2 of level, cross gate EPS block 9 position height. It is made with two benefits like this, one is that the molten iron that can pour into a mould at a high speed washes away the dirt on the bonding surface 2 of carbon steel part 3, be conducive to pure bonding surface, these dirts rise in rising head and remove, two is to heat carbon steel part 3, the temperature of bonding surface 2 is improved, increases the mixed binding power of bi-material.
Described step ingate EPS block 10 3. is flat shape ingate, it is possible to when preventing molten steel solidification, tup molten iron is aspirated feeding by cross gate 9, is conducive to increasing the density of tup.
