Abstract
The invention discloses a welding method of pipes of an air conditioning heat exchanger with different pipe diameters and a clamp device and relates to the welding process of the pipes of the air conditioning heat exchanger with different pipe diameters. The welding method includes that a round heat exchange copper pipe interface with the large pipe diameter is punched to be matched with a pipe with the small pipe diameter in shape through a clamp; the pipe with the small pipe diameter is inserted into the interface to be welded. The clamp device comprises a clamp base (1), a chuck (2) pivoted to the clamp base (1) and a fixed core (3) placed in the pipe interface. The chuck (2) comprises an upper clamp block (21) and a lower clamp block (22) which are pivoted to the clamp base (1), a half slot is arranged on one of the adjacent side surfaces where the free ends of the two clamp blocks are combined respectively, and the two half slots form a circular slot when the two clamp blocks are combined. According to the welding method and the clamp device, reducing used during welding is omitted, cost is greatly reduced, welding of one point of each capillary tube is reduced during welding, production operations are greatly simplified, and production efficiency is improved.
Description
Technical field
The present invention relates to the welding procedure of air-conditioner difference caliber pipeline, particularly the welding procedure of the difference caliber pipeline of air conditioner heat exchanger.
Background technology
At present, the heat exchange copper tube of heat exchanger of air condition and capillary are two calibers when differing larger copper pipe, and welding between the two needs to use reducing just can weld.Existing welding heat-exchanger mainly exists following problem: 1, the intercapillary welding of heat exchanger and distribution, because caliber differs too large, therefore must use a reducing to connect when welding, like this with regard to so that whole production technology complicated, loaded down with trivial details, and production cost has also increased; 2, two of reducing spot pitch cause the welding difficulty from little, affect production efficiency.
Summary of the invention
One of purpose of the present invention is to provide that a kind of intensity is high, cost is low, the welding method of the heat exchanger of air condition difference caliber pipeline of convenient welding.
Another object of the present invention is to provide a kind of grip device for the pipeline welding of heat exchanger of air condition difference caliber.
One of purpose of the present invention can realize like this, designs a kind of welding method of heat exchanger of air condition difference caliber pipeline, comprising:
Utilize grip device, the heat exchanging copper pipe interface that circular caliber is large strikes out the shape that cooperates with the little pipeline of caliber;
The pipeline that caliber is little inserts this interface and welds.
Further, the circular port interior diameter in the middle of the Interface Shape after the described punching press is slightly larger than the caliber of the small-caliber pipeline that will mate.
Further, described grip device directly operates the loop port of heat exchanger, and after the heat-exchanger brass pipe compression, the pipeline that caliber is little inserts and welds.
Another object of the present invention can realize like this, designs a kind of grip device for the pipeline welding of heat exchanger of air condition difference caliber, comprises clamping fixture seat, is arranged on chuck on the clamping fixture seat, is placed in the core of deciding in the pipe joint;
Described chuck comprises upper fixture block and the lower fixture block that is articulated on the clamping fixture seat, and two fixture block free ends merge adjacent side one half slot is set respectively, and when two fixture blocks merged, two half slots formed a circular groove.
Further, upper fixture block and lower fixture block are articulated on the same drive-connecting shaft.
Further, half slot is provided with groove in free end end face side.
The reducing that the present invention has used when having saved welding greatly reduces cost, welds less a some when thing followed is every capillary welding.For example, one has the common air-conditioning heat exchanger in ten loops just can save ten solder joints.Greatly simplified production operation, enhanced productivity.

The specific embodiment
The invention will be further described below in conjunction with embodiment.
A kind of welding method of heat exchanger of air condition difference caliber pipeline comprises:
Utilize anchor clamps, the heat exchanging copper pipe interface that circular caliber is large strikes out the shape that cooperates with the little pipeline of caliber; Such as Fig. 1, Fig. 5, Fig. 3, shown in Figure 4;
The pipeline that caliber is little inserts this interface and welds, as shown in Figure 6.
Circular port interior diameter in the middle of the Interface Shape after the described punching press is slightly larger than the caliber of the small-caliber pipeline that will mate.As shown in Figure 4, the circular port in the middle of this shape is in order to cooperate capillary to insert welding, and the circular configuration diameter in the middle of therefore is to come surely according to the caliber capillaceous that will mate, and requires to compress postcapillary and can directly insert and weld.
As shown in Figure 1 and Figure 2, a kind of grip device for the pipeline welding of heat exchanger of air condition difference caliber comprises clamping fixture seat 1, is arranged on chuck 2 on the clamping fixture seat 1, is placed in and decides core 3 in the pipe joint;
Described chuck 2 comprises that two half slots 23 formed a circular groove when the upper fixture block 21 that is articulated on the clamping fixture seat 1 and lower fixture block 22, two fixture block free ends merged adjacent side and one half slot, 23, two fixture blocks are set respectively merge.
Half slot 23 is provided with groove in free end end face side.The setting of groove has the gradient excessive when making copper pipe compressed.
During use, first iron core is injected in the copper pipe, utilize iron core to locate to compress, chuck 2 is clamped heat-exchanger brass pipe 4, External Force Acting merges fixture block 21 and lower fixture block 22 at chuck 2.Hydraulic pressure, the power that provides such as electronic can be provided external force.Fig. 3 is the heat-exchanger brass pipe 4 after compressing, and Fig. 4 is the heat exchanger copper pipe interface 5 after the anchor clamps compression.Owing to distributing capillary to have different pipe diameter sizes, therefore can different decide core and control mouth of pipe size after the compression and reach purpose with the welding of different tube diameters capillary by changing, strengthened versatility of the present invention.Fig. 5 is the operation chart of clamp, and grip device 7 directly operates the loop ports of heat exchanger 6, after the heat-exchanger brass pipe compression, capillary 8 inserted to weld gets final product.Fig. 6 is the welding schematic diagram, and heat friendship capillary 8 is inserted in the interface 5 of the heat-exchanger brass pipe 4 after the compression, directly welds.Whole operating process saves time, laborsaving, efficient is high.
