360 comprehensive search since its launch, with a larger 360 default browser promotion, has quickly gained a certain market share. If Baidu does not counterattack, 360 comprehensive search traffic may continue to rise.
On the evening of the 28th, Baidu started to fight back 360 search. In addition to the Baidu web search, all search from the 360 ​​search box was redirected to the Baidu home page. Yesterday, Baidu added a user reminder item after jumping to the home page. The user clicks this reminder to directly enter the Baidu search result page. For example, in the Qihoo 360 search, choose the Baidu News option and search for keywords. The page will jump to the Baidu home page. At the same time, the user will see the reminder option in the upper part of the search box. Click here to continue to visit Baidu News. result".
At the same time, sources from Baidu said that Baidu asked all agents and internal employees to unload 360 related products yesterday. Subsequently, Baidu agents in multiple places publicly announced that 360 related software may upload browsing records, cookies, and temporary file data to an external network server, and searched and browsed by others through 360 search, to protect the company's information and data security and employees. The privacy of individuals requires all employees to uninstall 360 software. â€
After Baidu made this change, the traffic from some 360 ​​websites on the integrated search site declined sharply. Many personal webmasters responded that traffic from the 360 ​​integrated search peaked on the 28th and then began to drop significantly. This shows that Baidu's "counterattack" has a noticeable effect.
However, analysts in the industry said that Baidu's move is very damaging to the user experience, and the effect of its crackdown may not be so obvious over time. After all, the 360's flagship has a lot of integrated products.
The fixed and rotor iron cores of large motors are divided into many overlapping segments. The punch plate of spot welded ventilation channel steel is placed between the iron core segments, namely, the ventilation groove plate, so as to form the radial air duct of fixed and rotor iron cores, which is used for heat dissipation and ventilation cooling of iron cores. The manufacturing quality of the ventilation groove plate must meet the strength requirements to ensure that no collapse or collapse occurs after loading. At the same time, the spot welding position of the ventilation channel steel on the punching plate should be accurate. After each section of iron core is pressed, the axial position of the ventilation channel steel should be in a straight line to ensure that the radial air duct does not distort and the axial straight line transmission of the pressing force of the iron core.
With the development of motor manufacturing technology and upgrading of manufacturing equipment, the manufacturing technology level of ventilation groove plate has been greatly improved. Currently supported processes are resistance welding and laser welding. Resistance welding is to place the welding parts between two electrodes, connect the current and apply a certain pressure, use the resistance heat generated when the current flows through the workpiece contact surface for heating, forming the local melting state of the welding parts. Laser welding is a kind of laser beam with high monochrome, strong aroma and high brightness by using the principle of excited atomic radiation. The laser beam, which is composed of coherent monochromatic photon stream with high energy density produced by laser, is used as energy source to bombard metal or non-metal, generate heat and melt it to achieve the purpose of welding.
According to the different requirements of the structure design and the characteristics of the respective spot welding process and the actual production needs, the motor manufacturers can
According to their own design capacity, equipment situation, production cycle, choose suitable for their own ventilation groove plate spot welding process, to ensure the manufacturing quality of ventilation groove plate.
