Abstract
The invention relates to a tooling for assembling and disassembling an expanding head support roller. The tooling comprises a tooling plate which has an arc-shaped structure, wherein a balancing weight is arranged at the end of the upper part of the tooling plate; a lifting lug is arranged on the top of the tooling plate; the lower part of the tooling plate is provided with a connecting plate; two locating holes are respectively formed in the two ends of the connecting plate; the connecting plate is fixed with the lower end of the support roller by a fastener. The tooling is compact and reasonable in structure and convenient to install; the support roller can be conveniently assembled and disassembled by the action of the tooling plate; the tooling is good in use safety, low in cost and high in working efficiency.
Description
Technical field
The present invention relates to hole enlargement equipment technical field, especially a kind of expanding head backing roll installing/dismounting frock.
Background technology
At present, in hole enlargement equipment, expanding head is critical component in hole enlargement equipment.Hole enlargement frock configuration expanding head, its shared limited space, shape and embedding structure complexity, the fixing guarantee expanding head of hole enlargement frock is stressed evenly, expanding head is stressed is: by the directly radial motion of contact steel pipe modular walls of the axial motion conversion of pull bar, reach the welding stress producing eliminate the forming pressure that produces of steel pipe and welding in forming process time, and ensure that steel pipe total length section diameter is basically identical.Expanding head, it comprises that multiple workpiece assemblies such as cone, voussoir, the T-shaped key of length, backing plate, module form, complete its assembling after directly pack on expanding machine.
In hole enlargement equipment, rod assembly is the critical component in hole enlargement equipment, and there is several places backing roll rod assembly inside, and the steel pipe of every kind of specification has corresponding backing roll.At steel pipe's production scene, the specification of steel pipe's production is not of uniform size, just need to frequently change, and backing roll also will often be changed thereupon.
Rod assembly of the prior art, comprise multiple workpiece such as pull bar, pull bar sleeve, front and back end nut, front and back end self-lubricating cover, centering flange, plane slide block, cambered surface slide block, backing roll and pivot shaft, backing roll in when assembling by suspender belt or the direct handling of steel rope and installation, dismounting, there is no special equipment, be inconvenient to install, dismantle.
Summary of the invention
The applicant, for the shortcoming in above-mentioned existing production technology, provides a kind of expanding head backing roll installing/dismounting frock rational in infrastructure, thereby actv. improves the safety that backing roll uses in the time of handling and installation, dismounting, installs easily, dismantles backing roll.
The technical solution adopted in the present invention is as follows:
A kind of expanding head backing roll installing/dismounting frock, comprise working plate, described working plate structure in the arc-shaped, described working plate upper end is provided with clump weight, and be positioned at working plate top and be provided with hanger, described working plate bottom is provided with connecting panel, and the two ends of described connecting panel have knock hole, and connecting panel is fixed by fastener and backing roll lower end.
Beneficial effect of the present invention is as follows:
Compact conformation of the present invention, reasonable, easy for installation, by the effect of working plate, can realize the installation and removal work of anvil roll easily, and safety in utilization is good, and cost is low, and work efficiency is high.
Brief description of the drawings
Fig. 1 is structural representation of the present invention.
Fig. 2 is the right elevation (omission backing roll) of Fig. 1.
Wherein: 1, clump weight; 2, hanger; 3, working plate; 4, backing roll; 5, connecting panel; 6, knock hole.
Detailed description of the invention
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described.
As depicted in figs. 1 and 2, the expanding head backing roll installing/dismounting frock of the present embodiment, comprise working plate 3, working plate 3 structure in the arc-shaped, working plate 3 upper end are provided with clump weight 1, and are positioned at working plate 3 tops and are provided with hanger 2, and working plate 3 bottoms are provided with connecting panel 5, the two ends of connecting panel 5 have knock hole 6, and connecting panel 5 is fixed by fastener and backing roll 4 lower ends.
In actual use procedure, because backing roll 4 is to be positioned at rod assembly below, frock need to be avoided the sleeve of pull bar.Connecting panel 5 is connected with backing roll 4, due to weight overbalance, asymmetric, in working plate 3 upper end, applicable clump weight 1 is installed, make it can not tilt, when assembling or dismounting backing roll 4, very simple, convenient, work efficiency is high.
More than describing is explanation of the invention, is not the restriction to invention, and limited range of the present invention, referring to claim, within protection scope of the present invention, can be done any type of amendment.
