Java box transition roller table analysis and treatment of deformation

Important structure. 2. Put forward a few years ago, the company's transition of certain production line equipment roller roller support part, the often heard \Last year, the second occurrence of this phenomenon float, leading to death of roller card, affecting production. February of this year, second-line cold repair, to identify both sides of the transition roller table slag me there was a serious side wall has been deformed inward tilt of the 15mm sidewall around the top of the head roll axis sets have been completely crushed, and worn a roller shaft, direct economic losses of several hundred thousand dollars. Box itself irrational structure of Java 2.1 (1) Java is a piece of the bottom plate, is not conducive to the free state in the thermal swell. (2) All welded steel plate inside layers, there is no room for expansion. Java 2.2 with the size box on the defective parts (1) cooling water jacket inside the gap with the shaft 4mm, too, according to the amount of thermal expansion of the shaft with appropriate margin calculation should be 10mm. (2) sets of cooling water hole and asked the gap between the shaft is 4mm, too. 2.3 residue inside the outer seal is poor,ugg sale, with a cooling water through two (tin bath bottom along the mouth end of the cooling-water channel and the lower part of the guide rollers are cooling water tank), and thus the space inside the box in the slag temperature room temperature than the glass top is much lower. 3. Design Modification of the review above three reasons, is caused by deformation of slag tank, causing the death of roller card, the main reason for the problems, the design of the new comprehensive and taken appropriate measures. Java 3.1 Java container bottom plate and side of the internal partitions designed as fixed, while activities in order to free expansion plate. 3.2 Java related components inside a proper combination of (1) Java box body and shaft kit, Sheung Shui, the gap was originally 4mm, is designed for 10mm, an axial elongation to meet the needs. - 2000.4 �� CHINABUILDINGMATERIALEQulPMENT - (2) comprising a cooling water hole and shaft diameter of the gap was originally 4mm, is designed to 8mm (each side),uggs kopen, while the water jacket in the design process, increase the water hole kit the geometric tolerance, to ensure the accuracy of the water processing units, comprising the water hole to facilitate reasonable match with the shaft. 3.3 to take measures to improve the slag inside the space temperature (1) tin bath along the lower part of the cooling-water port, the previous water as cooling medium, is designed for 1 / 3 with recycled water, which leads to 2 / 3 of nitrogen, water temperature of 20 degrees, the outlet temperature of 35 degrees. This will ensure the process along the tin bath on the mouth of the cooling requirements, and improve the local temperature. (2) Change the lower roller seal structure: the lower part of the original roller seal is supported by the bridge of graphite, graphite blocks to achieve spring roll to withstand the lower seal. The temperature of 600 degrees in the spring also has the effect of deflection. I used the production line produced by the central deflection of the bridge is generally about 15-20mm (on the one hand is the deformation of the deflection of the bridge itself, the other is the deflection produced by roller pressure on the bridge), this middle of the bridge have the deflection of the bridge on the graphite by the overall regulation to seal the lower roller is Mifengbuyan false. The transition of the domestic use of the lower roller table rollers are basically seal the form, in theory, can be sealed to live, in fact, due to thermal deformation effect, this structure can not achieve a good seal. For this particular case, the design of the new design uses the following structure: the bridge structure of graphite and the guide slot into sub-regulation by the overall adjustment in the bridge,uggs kopen, through the slag box outside the rotation of the nut, to promote the ramp iron from the top box installed in the graphite roll graphite contacts until the seal. In this way, which places much of graphite from the roll to which a regulation to solve the deformation of the bridge and roll is not to make contact with graphite seal not achieve the major problem of cooling water guide slot guide slot is used to prevent deformation. Into sub-regulation by the overall adjustment, guided this part of the cooling water tank and is not required. In this way, to strengthen both the lower part of the sealing rollers, but also increase the internal temperature of slag box. In addition, the design of new blizzard gate structure. Strengthened the blizzard closed the door. 4. Summarized by the above measures, an increase of slag Chamber of transition (glass bottom) of the seal, to improve the temperature of the glass bottom, so that board is basically under the temperature tends to balance. Basic balance of temperature,Discount Tory Burch, greatly reducing the slag box deformation and deformation of roller. After the second cold repair, nearly a year of operation, the drive part of the roller produces strange sounds, roll the phenomenon to be stuck there. Sealed by the lower roller structure transformation, greatly improving the seal within the slag box, so that the pressure from the tin bath at the end of a dozen up to more than thirty Pa Pa, for the production of high quality float glass to provide better conditions . ��
