Description
Technical field
The invention belongs to technical field of refrigeration equipment, especially has with a kind of small pressure container surface derusting manufacturing process
Close.
Background technology
In common refrigeration plant, such as oil-liquid separator, vapour liquid separator, muffler, reservoir small pressure container,
Cylinder and the end cap at cylinder both ends made of steel are generally included, input hole and delivery outlet are respectively arranged with two end cap,
Copper connecting tube is welded with input hole and delivery outlet, the manufacture method of existing small pressure container is divided into three steps：First, steel
Manufactured cylinder and end cap are by chlorohydric acid pickling, the cleaning of twice clear water, antirust solution immersion and dry；Then, end cap and copper are connected
Adapter welding forms copper steel engaging member, copper steel engaging member through superheated water oil removing, the rinsing of twice clear water, chlorohydric acid pickling,（Hcl+H2SO4
+H2NO3）Combine liquid pickling, clear water rinsing, chromic acid pickling, the cleaning of twice clear water, NaOH neutralizations, the cleaning of twice clear water, antirust solution
Immersion and drying；Finally, will be formed after the welding of cylinder and copper steel engaging member it is overall, at the step on end cap and cylinder lateral surface
Carbon-dioxide arc welding is carried out, it is overall to carry out phosphorating treatment, crystallization pit is formed on surface, is painted.Existing this manufacture
There is the various complexity of process in method, it is relatively low that chemical treatment has potential safety hazard, production efficiency, the defects of polluting environment.
The content of the invention
The purpose of the present invention is intended to overcome the manufacture method of existing small pressure container the various complexity of process to be present, at chemistry
It is relatively low potential safety hazard, production efficiency to be present in reason, the defects of polluting environment, there is provided one kind is using physical principle, processing technology is simple,
The small pressure container surface derusting manufacturing process of efficiency high.
Therefore, the present invention uses following technical scheme：Small pressure container surface derusting manufacturing process, passes through steel casting
Cylinder and the end cap at cylinder both ends are molded into, it is characterized in that, first, cylinder is surface-treated by shot-blast process, using throwing
Ball machine carries out ball blast, and cylinder is put into shot-blasting machine by a hanger overhanging support, and the dirt on ball blast rear cylinder body surface, rusty stain etc. are clear
Reason, and surface forms pit；Then, end cap is welded to form copper steel part with copper connecting tube, and copper steel part is pressed from both sides by a Workpiece clamping head
Hold fixed and rotated by Workpiece clamping head band with copper steel part, Workpiece clamping head is installed on the sandblasting chamber of sand-blasting machine by support plate support
Interior, support plate band is revolved round the sun with Workpiece clamping head with support plate, and sandblasting is carried out using sand-blasting machine.
As the supplement to above-mentioned technical proposal and perfect, present invention additionally comprises following technical characteristic.
The impeller diameter of the shot-blasting machine used is 250mm, a diameter of 0.5 ~ 0.8mm of bullet, and ball blast amount is 150kg/
min。
The present invention can reach following beneficial effect：By physical methods such as ball blast technique, blasting crafts to cylinder and copper
The surface of steel engaging member and weld carry out surface derusting processing, make surface and the welding of drum surface and copper steel engaging member
Place forms pit, improves spray painting adhesive force, improves production efficiency, avoids polluting environment.
Embodiment
The embodiment of the present invention is described in detail below.
The present invention is molded into cylinder and the end cap at cylinder both ends by steel casting, and first, cylinder is entered by shot-blast process
Row surface treatment, uses impeller diameter to carry out ball blast, a diameter of 0.5 ~ 0.8mm of bullet for 250mm shot-blasting machine, and ball blast amount is
150kg/min, cylinder are put into shot-blasting machine by a hanger overhanging support, and the dirt on ball blast rear cylinder body surface, rusty stain etc. are cleaned,
And surface forms pit；Then, end cap is welded to form copper steel part with copper connecting tube, and copper steel part is clamped solid by a Workpiece clamping head
Determine and rotated by Workpiece clamping head band with copper steel part, Workpiece clamping head is installed on the sandblasting intracavitary of sand-blasting machine, branch by support plate support
Support plate band is revolved round the sun with Workpiece clamping head with support plate, and sandblasting is carried out using sand-blasting machine.Pass through the physics sides such as ball blast technique, blasting craft
Method carries out surface derusting processing to cylinder and the surface of copper steel engaging member and weld, makes drum surface and copper steel engaging member
Surface and weld formed pit, improve spray painting adhesive force, improve production efficiency, avoid pollute environment.
