Abstract
The utility model discloses a cooling and sealing device in a welding wheel, which comprises the welding wheel and a rotary joint, wherein the welding wheel is connected with the rotary joint in a threaded way along the axial direction, and at least one sealing washer is installed at the joint part of the welding wheel and the rotary joint. With the adoption of the cooling sealing device, in the working process of the welding wheel, a sealing ring can not be worn, cooling water is efficiently prevented from leaking; and when the welding wheel rotates, the occlusion degree of the welding wheel and the rotary joint can be increased at any time, so that the sealing performance is further improved.
Description
Technical field
The utility model relates to the steel plate welding technology field, is specifically related to coolant seal device in a kind of weld wheel.
Background technology
As shown in Figure 1, during the steel plate welding, with two steel band ends overlap joint, weld wheel is crimped on the outer surface of two steel band clinch earlier, the conductive plate of weld wheel itself is connected in the secondary tap of welding resistance transformer, formed the secondary loop with transformer, electric current brings out from transformer one, takes turns to the afterbody of steel band in advance by welding, contact by steel band again, to the head of back row steel band, last current reflux makes and passes to bigger electric current between steel band to the other end of transformer; Electric current impels the heating of two steel band contact-making surfaces, and temperature raises fast and reaches the steel band fusing point, makes the contact-making surface local melting; This moment, steel band itself just was subjected to having the precompression of the weld wheel of cylinder, and under pressure, two steel band clinch combine together; After condensing, soldering opening cooling can reach or a little more than the intensity of steel band base material.
During work, because the rotation that weld wheel does not stop under axle drives, need to bear very large pressure and rotatory force again, if will obtain good welding effect, just must be to its cooling that continues, yet, present stage, generally the type of cooling of Cai Yonging is that the outside adds water cooling, and this kind water-cooling structure causes whole welder complex structure, and not easy to operate, influence working environment.
The inner colded mode of part process using is also arranged, be to use sealing ring to prevent what cooling water from leaking outside between cooling stand briquetting and the weldering wheel shaft by crush seal; But because of the weldering wheel shaft rotates, and the cooling stand briquetting is a fixed static, during weld wheel work, sealing ring is received the friction of cooling support and welding wheel shaft, very easily wearing and tearing, sealing ring causes and leaks just because of wearing and tearing lose the crush seal function behind the work certain hour, influences the normal operation of weld wheel.
The utility model content
At the deficiencies in the prior art, the purpose of this utility model is intended to provide coolant seal device in a kind of weld wheel, and it is not fragile, the normal operation of assurance weld wheel that can be over a long time.
For achieving the above object, the utility model adopts following technical scheme:
Coolant seal device in the weld wheel comprises weld wheel and swivel joint, and described weld wheel and swivel joint are spirally connected vertically, at its two seam crossing at least one seal washer are installed.
One end of described weld wheel is provided with an installation cavity, and the inwall of described installation cavity offers internal thread, and an end outside of described swivel joint offers the external screw thread that matches.
The direction of rotation of described internal thread and externally threaded direction of rotation and described weld wheel.
The seam crossing of described weld wheel and swivel joint is equipped with two seal washers.
The cross section of described seal washer is O shape.
Described swivel joint is provided with cooling water inlet and cooling water outlet.
Coolant seal device in the weld wheel that the utility model is set forth, its beneficial effect is:
1, in the weld wheel course of work, can not cause wearing and tearing, effectively prevent the cooling water seepage sealing ring;
When 2, weld wheel rotates, can increase the degree of engagement with swivel joint at any time, further increase sealing.
Description of drawings
Fig. 1 is prior art steel band welding schematic diagram;
Fig. 2 is the structural representation of coolant seal device in a kind of weld wheel of the utility model.
The specific embodiment
Below, in conjunction with the accompanying drawings and the specific embodiment, coolant seal device in the weld wheel of the present utility model is described further, so that clearerly understand the utility model technological thought required for protection.
As shown in Figure 2, be coolant seal device in a kind of weld wheel of the present utility model, it comprises weld wheel 1 and swivel joint 2, weld wheel 1 an axial end is provided with installation cavity 11, its inwall is provided with internal thread 12, mate at an end of swivel joint 2 and the size of installation cavity 11, and offer external screw thread 21 with internal thread 12 couplings in its this periphery, end, weld wheel 1 links together by internal thread 12 and external screw thread 21 with swivel joint 2, and is provided with the sealing ring 22 that is socketed with two O shapes side by side at the seam crossing of weld wheel 1 and swivel joint 2; Swivel joint 22 is provided with cooling water inlet 3 and coolant outlet 4.
Because swivel joint 2 connects with 1 of weld wheel, just can avoid the relative motion of sealing ring with the weldering wheel shaft, reduced wearing and tearing to sealing ring 22, improved sealing property; The hand of spiral of above-mentioned internal thread 12, external screw thread 21 is opposite with the hand of spiral of standard, also is and the direction of rotation of weld wheel 1 that in weld wheel 1 course of work, the interlock meeting is more and more tighter, can prevent effectively that cooling water from leaking outside simultaneously.
For a person skilled in the art, can make other various corresponding changes and distortion, and these all changes and distortion should belong within the protection domain of the utility model claim all according to technical scheme described above and design.
