Description
Technical Field
The invention relates to the field of welding, in particular to a welding wheel assembly device for a strip steel online narrow lap joint seam welding machine.
Background
The welding wheel assembly device is an important component of the online narrow lap joint and seam welding machine for the strip steel, and has the function of transmitting current to the lap-jointed strip steel as completely as possible. Therefore, the quality and stability of the welding wheel assembly device are related to the normal operation of the whole equipment, and the effect of strip steel welding is almost related to the quality and stability.
In the prior art, a welding wheel assembly device of a narrow lap joint seam welding machine comprises an upper welding wheel assembly and a lower welding wheel assembly, wherein the lower welding wheel assembly is arranged at the bottom of a C-shaped frame, and the upper welding wheel assembly is arranged at the upper part of the C-shaped frame. The main structures of the upper welding wheel assembly and the lower welding wheel assembly are consistent, but the upper welding wheel assembly can realize the actions of pressing and lifting under the driving of the air cylinder or the oil cylinder. Before welding, the upper welding wheel is pressed down onto the lower welding wheel, so that the upper electrode wheel is in contact with the lower electrode wheel and has a certain pressure, the C-shaped frame moves towards the transmission side, the upper electrode wheel and the lower electrode wheel are rolled on the belt head and the belt tail which are overlapped together, and as the contact resistance exists between the belt head and the belt tail which are overlapped together, as shown in figure 4, the current on the upper electrode wheel and the lower electrode wheel generates heat when passing through the belt head and the belt tail, so that the strip steel is welded together in a melting way. Because the upper electrode wheel and the lower electrode wheel are disc-shaped and are arranged on the wheel shaft capable of freely rotating, continuous welding can be realized in the moving process of the C-shaped frame.
In the conventional welding wheel assembly, as shown in fig. 5, the main body of the welding wheel assembly is an electrode wheel support, a disc-shaped electrode wheel is mounted on a wheel shaft, the wheel shaft is mounted in a stepped circular hole of the electrode wheel support through a cylindrical bearing at the front end and a ball bearing at the tail end, two bearings are separated from the electrode wheel support by insulating sleeves, and the wheel shaft is locked by a nut. The middle of two bearing positions on the wheel shaft is a conical surface, a conical shaft sleeve is sleeved on the conical surface, the conical shaft sleeve is clamped on the electrode wheel support through a key groove, and the inner conical surface of the conical shaft sleeve is attached to the outer conical surface of the wheel shaft under the action of spring force. In the welding process, the electrode wheel and the wheel shaft rotate continuously, the outer conical surface of the wheel shaft and the inner conical surface of the cone shaft sleeve rotate and rub with each other, and the purpose that the current on the electrode wheel support is transmitted to the wheel shaft and the electrode wheel through the cone shaft sleeve is achieved.
Meanwhile, because heat can be generated in the process of transmitting current, the welding wheel assembly also comprises a cooling circulating water system, a blank cap communicated with a cooling water pipeline is arranged at the tail end of the welding wheel assembly, and a water pipe on the inner side of the blank cap guides cooling water into a deep hole in the center of the wheel shaft to achieve the purpose of cooling the welding wheel assembly. And lubricating oil is injected into an inner cavity between the wheel shaft and the stepped hole of the electrode wheel support and is used for lubricating the bearing and the inner conical surface and the outer conical surface which are mutually rubbed.
However, the above structure has several major problems:
1. the structure is too complex, in the internal structure, a conductive part (taper sleeve) of a core is arranged in an electrode wheel support, so that the processing and assembly of parts are very difficult, the use condition of the conductive part is difficult to observe in production, and the maintenance is difficult;
2. when the internal conical shaft sleeve is overhauled and replaced, the whole structure of the welding wheel assembly needs to be completely disassembled, the workload is huge, the specialty is too strong, a specially-experienced master can be used for completing the operation, a general master of a fitter cannot be competent for the operation, and the normal operation of a production line is seriously influenced by the fine and complicated maintenance work;
3. a lubricating system and a cooling system are integrated in the welding wheel assembly, the two systems are isolated by using a sealing ring inside the welding wheel assembly, but in the actual use process, the lubricating oil and the cooling water are often communicated with each other due to the quality or the service life of the sealing ring, so that unnecessary loss is caused;
4. the axle and the conical shaft sleeve are mutually milled and matched in the primary installation process, so that the conductive area is as large as possible, the problems that the conductive area is too small when current passes through and the conical shaft sleeve and the axle are seriously burnt due to heating caused by overlarge current passing in unit area are avoided, in the actual use process, conical surfaces which are mutually rubbed are abraded, and although a spring on the right side of the conical shaft sleeve can tightly push the conical shaft sleeve to eliminate a gap generated by abrasion, the effect is poor;
5. because must have good electric conductivity, the welding wheel assembly has adopted a large amount of copper materials, for example the electrode wheel support is the brass foundry goods, and the whole material of shaft is chromium zirconium copper, and the taper sleeve material is tin bronze, and not only whole cost is fairly high, is unfavorable for the cost control of equipment, more causes the user to purchase welding wheel assembly spare parts cost and is fairly high, increases user's burden.
Therefore, the traditional welding wheel assembly can not be applied to the existing welding equipment in aspects of structural reasonability, cost control and the like, and a set of brand-new welding wheel assembly is urgently needed to be developed, so that the structure is more reasonable, the maintenance is convenient, the cost is reduced as much as possible, and the whole equipment is more competitive.
