Description
Technical field
The utility model relates to a kind of door gasket angle-welding machine that is used to weld the seal strip for refrigerator door bight, specifically to the improvement of existing corner welding machine structure.
Background technology
In manufacturing refrigerator, freezer door strip of paper used for sealing process, need gasket four bights are welded.Corner welding machine has two kinds of diplopore welding machine and single hole welding machines.In order to guarantee welding quality, need to adopt vacuum plant to carry out vacuum suction.And existing vacuum plant adopts vavuum pump generation vacuum to adsorb the gasket that is placed in the mould.The advantage of employing vavuum pump absorption is to guarantee the welding precision of gasket product, guarantees that solder side is smooth, and weld is not easy to crack, and product can use in refrigerator, refrigerator-freezer for a long time.
Also brought some problems owing to adopt vavuum pump to produce vacuum, its deficiency is: 1. energy consumption height, improved production cost of products.2. in case vavuum pump damages, the necessary shutdown maintenance of equipment is changed accessory, and the maintenance cost height, and maintenance technique requires high, needs professional vacuum maintenance personal just can finish.3. owing to the vavuum pump continuous firing, vavuum pump work a period of time, the moving component of vavuum pump is easy to wear, is difficult for being found, and vacuum does not reach the regulation requirement, can directly influence the welding quality of gasket.
How solving above-mentioned deficiency, then is the design problem that the utility model faced.
The utility model content
The utility model provides a kind of door gasket angle-welding machine, and it can solve energy consumption height, maintenance cost height and moving component that prior art the exists problem such as due vacuum that do not reach easy to wear.
In order to reach the purpose that solves the problems of the technologies described above, the technical solution of the utility model is:
A kind of door gasket angle-welding machine, it comprises vacuum plant, described device comprises the vacuum generator valve body, be provided with the high pressure valve on valve body, described high pressure valve communicates with compressed air, in high pressure valve exit one air cavity is arranged, on the valve body of high pressure valve vertical direction, be provided with the vacuum valve, one end of vacuum valve communicates with described air cavity, and the other end communicates with vacuum way in the gasket weld mold, also is provided with the outlet passageway that communicates with air cavity on valve body.
For making velocity of compressed air further improve, learn principle according to air fluid, under the situation of same flow, sectional area is more little, and flow velocity is high more, and is so the compressed air channel of high pressure valve is from large to small from air inlet to gas outlet, stepped.
Because high-voltage high-speed airflow directly communicates with atmosphere, can produce very big noise, as further improvement of the utility model, is provided with muffler in described outlet passageway exit, reach the purpose that reduces noise.
Compared with prior art, advantage of the present utility model and good effect are: 1. the utility model makes vacuum valve place produce the high vacuum negative pressure by swiftly flowing compressed air, adsorb the gasket that is placed in the mould with this, substituted original vavuum pump, make the production cost of door gasket angle-welding machine reduce greatly, fault rate is extremely low, has saved maintenance cost, and reliability strengthens.2. owing to be to produce vacuum by compressed air, vacuum effectiveness has consistently overcome the vacuum phenomenon not up to standard that the wearing and tearing of vavuum pump moving component may cause, and has guaranteed welding quality.
Description of drawings
Fig. 1 is the vacuum plant structural representation of described the utility model door gasket angle-welding machine;
Among Fig. 1: 1 vacuum generator valve body; 2 high pressure valves; 3 vacuum valves; 4 mufflers; 5 gasket weld molds; 6 air cavitys; 7 outlet passageways; 8 compressed air; 9 compressed air channels.
The specific embodiment
The utility model adsorbs the gasket that is placed in the mould by the vacuum that adopts vacuum plant to produce, and can substitute vavuum pump fully, and fault rate is extremely low, reduces the production cost of door gasket angle-welding machine greatly, and is energy-conservation, reliable.
Embodiment one, the vacuum plant of described door gasket angle-welding machine comprises vacuum generator valve body 1, on valve body, be provided with high pressure valve 2, described high pressure valve 2 communicates with compressed air 8, in high pressure valve exit one air cavity 6 is arranged, be provided with vacuum valve 3 on the valve body of high pressure valve vertical direction, an end of vacuum valve 3 communicates with described air cavity 6, the other end communicates with vacuum way in the gasket weld mold, also is provided with the outlet passageway 7 that communicates with air cavity on valve body.
The compressed air channel 9 of high pressure valve is from large to small from air inlet to gas outlet, and is stepped.Learn principle according to air fluid, under the situation of same flow, sectional area is more little, and flow velocity is high more, so adopt the such structure of compressed air channel that reduces step by step, flow velocity progressively improves, and better meets the high velocity air that produces negative pressure of vacuum.
Because high-voltage high-speed airflow directly communicates with atmosphere, can produce very big noise, is provided with muffler 4 in described outlet passageway exit, reach the purpose that reduces noise.
Concrete application principle of the present utility model is such:
When the gasket for the treatment of leg inserts weld mold by the operator, when resetting after the heater rising is heated gasket, when magnetic switch is lighted in the heating cylinder, vacuum solenoid is opened, at this moment high pressure gas flow at high speed in the direction of arrows, at this moment, just produced the high vacuum negative pressure according to the fluidics principle at vacuum valve place, because the vacuum way in vacuum valve and the gasket weld mold communicates, so in weld mold, just produced high vacuum, gasket to be welded is adsorbed on tightly on the chamber wall of weld mold, weld mold high speed matched moulds under the drive of cylinder has at this moment been finished the leg process of whole gasket.
Adopt this welding manner of the present utility model and produce high vacuum with vavuum pump; its objective is duplicate; because vavuum pump need not shut down work; in case vavuum pump breaks down; the door gasket angle-welding machine shutdown maintenance of will having to; had a strong impact on production, and the maintenance cost of vavuum pump is also very high.Substitute vavuum pump with vacuum generator; its benefit vacuum generating device is extremely difficult to be damaged, and needs repairing hardly, as long as the high pressure valve has high pressure gas to insert; will produce the moment vacuum; and can be by the PLC control of corner welding machine, vacuum solenoid is the moment switching as required, can save a large amount of energy like this; do not need to shut down and safeguard; improve production efficiency relatively, also saved a large amount of maintenance costs simultaneously, guaranteed the normal operation of complete machine.
Certainly; above-mentioned explanation is not to be to restriction of the present utility model; the utility model also is not limited in above-mentioned giving an example, and variation, remodeling, interpolation or replacement that those skilled in the art are made in essential scope of the present utility model also should belong to protection domain of the present utility model.
