Abstract
The invention aims to provide a copper bush installation process. According to the thermal expansion and cold extraction principle, the size of a copper bush is reduced, then the copper bush is installed on a component and the problem that the copper bush is difficult to install is solved. The size of the copper bush is reduced after the copper bush is cooled, the copper bush can be conveniently installed, installation efficiency of the copper bush is improved, damage to the copper bush and the component caused by the fact that the copper bush is knocked violently is reduced, quality of components of an injection molding machine and a die-casting machine is improved and the service life is prolonged.
Description
Technical field
The present invention relates to injection machine and die casting machine manufacture field, particularly relate to a kind of mounting process of the convenient copper sheathing installed on injection machine and die casting machine accessory.
Background technology
When manufacturing injection machine and die casting machine, the parts in injection machine and die casting machine need to install copper sheathing, and to improve the quality of parts, guard block is not damaged.And screw or rivet cannot be used to install because copper sheathing is installed, therefore need to be connected with the tensile force between parts by copper sheathing itself, and due to the size of copper sheathing can not be too much less than parts, therefore when mounted can be very difficult, carrying out installation copper sheathing by knocking, damage can be caused to copper sheathing and parts.Therefore, the problem solving copper sheathing installation difficulty just seems particularly important.
Summary of the invention
The object of this invention is to provide a kind of mounting process of the convenient copper sheathing installed on injection machine and die casting machine accessory, by the principle of expanding with heat and contract with cold, first the size of copper sheathing is reduced, then be arranged on parts, solve the problem that copper sheathing installs difficulty.
The invention provides a kind of copper sheathing mounting process, described installation steps are following steps compositions:
Step one: put into refrigerator by needing the copper sheathing installed and carry out freezing 3 ~ 6 hours;
Step 2: the copper sheathing after cooled is installed to the position needing to install by the mode of knocking;
Step 3: can use after rising again under the parts installing copper sheathing are placed on normal temperature condition 3 ~ 4 hours.
Further improvement is: temperature freezing in described step one is-80 DEG C ~-95 DEG C, and freezing complete after need to install at once.
Further improvement is: use the hammer with sheath to knock when knocking copper sheathing in described step 2, prevents from damaging copper sheathing.
Further improvement is: auxiliary blower or device of rising again can carry out acceleration and rise again when rising again under normal temperature condition in described step 3, reduce and rise again the time.
Beneficial effect of the present invention: by cooling copper sheathing, the size of copper sheathing is reduced, conveniently copper sheathing is installed, improve the efficiency that copper sheathing is installed, and the damage decreased owing to knocking copper sheathing that copper sheathing causes and parts energetically, improve the quality of injection machine and die casting machine parts, increase the service life.
Detailed description of the invention
In order to deepen the understanding of the present invention, below in conjunction with embodiment, the invention will be further described, and this embodiment only for explaining the present invention, does not form limiting the scope of the present invention.
Embodiment one:
The present embodiment provides a kind of copper sheathing mounting process, and described installation steps are following steps compositions:
Step one: put into refrigerator by needing the copper sheathing installed and carry out freezing 5 hours;
Step 2: the copper sheathing after cooled is installed to the position needing to install by the mode of knocking;
Step 3: can use after rising again under the parts installing copper sheathing are placed on normal temperature condition 3 hours.
Temperature freezing in described step one is-90 DEG C, and freezing complete after need to install at once.Use the hammer with sheath to knock when knocking copper sheathing in described step 2, prevent from damaging copper sheathing.Auxiliary blower or device of rising again can carry out acceleration and rise again when rising again under normal temperature condition in described step 3, reduce and rise again the time.
Embodiment two:
The present embodiment provides a kind of copper sheathing mounting process, and described installation steps are following steps compositions:
Step one: put into refrigerator by needing the copper sheathing installed and carry out freezing 6 hours;
Step 2: the copper sheathing after cooled is installed to the position needing to install by the mode of knocking;
Step 3: can use after rising again under the parts installing copper sheathing are placed on normal temperature condition 4 hours.
Temperature freezing in described step one is-95 DEG C, and freezing complete after need to install at once.Use the hammer with sheath to knock when knocking copper sheathing in described step 2, prevent from damaging copper sheathing.Auxiliary blower or device of rising again can carry out acceleration and rise again when rising again under normal temperature condition in described step 3, reduce and rise again the time.
By cooling copper sheathing, the size of copper sheathing is reduced, conveniently copper sheathing is installed, improve the efficiency that copper sheathing is installed, and the damage decreased owing to knocking copper sheathing that copper sheathing causes and parts energetically, improves the quality of injection machine and die casting machine parts, increases the service life.
