Abstract
The utility model relates to a tooling for mounting and dismounting a supporting roll of a diameter-expanding head. The tooling comprises a tooling plate, wherein the tooling plate adopts a circular arc-shaped structure; a weight block is mounted at the end part of the upper part of the tooling plate; a lifting lug is positioned and arranged at the top of the tooling plate; a connecting plate is mounted at the lower part of the tooling plate; positioning holes are formed in the two ends of the connecting plate; the connecting plate is fixed to the lower end of the supporting roll through fastening parts. The tooling is compact and reasonable in structure, and convenient to mount; through the action of the tooling plate, the supporting roll can be mounted and dismounted conveniently. Therefore, the tooling is good in using safety, low in cost, and high in working efficiency.
Description
Technical field
The utility model 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 are complicated, the fixedly assurance expanding head of hole enlargement frock is stressed evenly, expanding head is stressed is: by the direct radial motion of contact steel pipe modular walls of the axial motion conversion of pull bar, reach the welding stress producing while eliminating forming pressure that steel pipe produces in forming process and welding, and guarantee that steel pipe total length section diameter is basically identical.Expanding head, it comprises that a plurality of workpiece assemblies such as cone, voussoir, the T-shaped key of length, backing plate, module form, and after completing its assembling, directly packs 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.On-the-spot in steel pipe's production, 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 a plurality of 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-purpose equipment, be inconvenient to install, dismantle.
Utility model content
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 is used when handling and installation, dismounting, installs easily, dismantles backing roll.
The technical scheme that the utility model adopts 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.
The beneficial effects of the utility model are as follows:
The utility model compact conformation, 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.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
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.
The specific embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present utility model 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 to explanation of the present utility model, is not the restriction to utility model, and the utility model limited range, referring to claim, within protection domain of the present utility model, can be done any type of modification.
