Fig. 1 is a schematic diagram of a front end installation structure of a collapsible mandrel of an uncoiler.
Fig. 2 is a schematic diagram of a rear end mounting structure of a collapsible mandrel of an uncoiler.
The device comprises a 1 expansion mandrel, a 2 main shaft, a 3 moving sleeve, a 4 guide flat key, a 5 end cover, a 6 common flat key, a 7 shaft end copper sleeve, a 8 expansion cylinder, a 9 single-row tapered roller bearing, a 10 one-way thrust ball bearing, a 11 choke plug, a 12 stop ring and a 13 conical retainer ring.
Detailed Description
The uncoiler expansion mandrel mounting structure shown in fig. 1-2 is characterized in that a main shaft 2 and a movable sleeve 3 are sequentially sleeved outside the front end of the expansion mandrel 1. The movable sleeve 3 is connected with the arched plate for tensioning the steel coil through an upper inclined sliding block and a lower inclined sliding block which can slide relatively. The main shaft 2 and the movable sleeve 3 are connected through a guide flat key 4. The front end of the collapsible mandrel 1 is sleeved with an end cover 5, the collapsible mandrel 1 is connected with the end cover 5 through a common flat key 6, and the outer edge of the end cover 5 is connected with the end face of the movable sleeve 3 through a bolt. Therefore, when the expansion mandrel 1 moves axially relative to the main shaft 2, the movable sleeve 3 can be driven to slide, so that the steel coil is expanded by the arched plate. The inner surface of the front end of the main shaft 2 is provided with a first annular gap, a shaft end copper sleeve 7 is arranged in the first annular gap, the inner diameter of the shaft end copper sleeve 7 is adapted to the inner diameter of the collapsible mandrel 1, and sliding abrasion is reduced. The inner side of the shaft end copper sleeve 7 is provided with an oil groove, so that lubricating oil can be injected into the oil groove at regular intervals, and the whole collapsible mandrel 1 is lubricated in the rotating and sliding process.
The front end of the collapsible mandrel 1 is provided with a pressing device. The compressing device comprises a choke plug 11, a stop ring 12 and a conical retainer ring 13 which are sequentially in compression joint. The choke plug 11 is covered at the end part of the collapsible mandrel 1 and is connected through bolts, a ring groove is arranged at the installation position of the collapsible mandrel 1 corresponding to the stop ring 12, and the conical retainer ring 13 is pressed against the adjacent end cover 5, so that the connection reliability is ensured. Thereby when the main shaft 2 rotates, the collapsible mandrel 1 is driven to synchronously rotate.
