Abstract
The utility model provides a lifting device of a welding steel tube straightening mold, and relates to the production equipment field of welding steel tubes. The lifting device comprises an upper mold installation plate, wherein an upper mold fixing frame is installed on the lower end face of the upper mold installation plate, and an upper mold body is installed at the lower end of the upper mold fixing frame. The lifting device is characterized in that a lifting frame is fixed on the upper mold installation plate, the lifting frame comprises a cross rod with a roll sleeve sleeved on the outer side of the cross rod, two ends of the cross rod are fixed on the upper mold installation plate through a longitudinal rod, and external threads are arranged at the upper end of the longitudinal rod and are fixed on the upper mold installation plate through a nut. The lifting device is simple in structure and reasonable in design; in the process of straightening for a steel tube through a mold, when an upper mold of the mold rises, the steel tube can be lifted through the lifting frame, the roll sleeve is sleeved on the cross rod of the lifting frame, and accordingly the steel tube can move on the lifting frame; and in the process of straightening, the steel tube can be lifted through the motive power provided by a pressure machine, the steel tube can move up and down along with the upper mold, operation of workers is facilitated, and machining efficiency is high.
Description
Technical field:
The utility model relates to welded still pipe production equipment field, relates in particular to a kind of lifting device of welded still pipe straightening die set.
Background technology:
Welded still pipe also claims welded tube, is with steel plate or with welding the steel pipe of making behind the steel process cans.The welded still pipe production technology is simple, and production efficiency is high, and description is many, and equipment money is few, but common intensity is lower than seamless steel pipe.
Since the thirties in 20th century, along with developing rapidly and the progress of welding and inspection technology of quality strip steel rolling production, weldquality improves constantly, and the description of welded still pipe is increasing, and has replaced seamless steel pipe in increasing field.Welded still pipe is divided into ERW and spiral welded pipe by the form of weld seam.The intensity of spiral welded pipe is generally high than ERW, can produce the larger welded tube of caliber with narrower blank, can also produce the different welded tube of caliber with the blank of same width.But compare with the straight-seam pipes of equal length, fusion length increases by 30 ~ 100%, and speed of production is lower.The ERW production technology is simple, and production efficiency is high, and cost is low, and development is very fast.
The welded still pipe production process need to be carried out straightening processing to it with steel plate or with steel by mould through the steel pipe of cans.In the prior art, steel pipe mainly relies on suspender that steel pipe is sling when aligning by mould, material loading and blanking process not easy to operate and control, production efficiency is low.
The utility model content:
Technical problem to be solved in the utility model is to overcome the defective of prior art, and a kind of lifting device of welded still pipe straightening die set easy to use is provided.
Technical problem to be solved in the utility model realizes by the following technical solutions.
A kind of lifting device of welded still pipe straightening die set, comprise mold mounting plate, upper mold mounting plate is equipped with the patrix fixed mount on the lower surface, die body is installed in patrix fixed mount lower end, it is characterized in that: be fixed with hoisting frame on the described upper mold mounting plate, hoisting frame comprises that outer cover has the cross bar of roller shell, and the cross bar two ends are fixed on the upper mold mounting plate by vertical pole.
Described vertical pole upper end is shaped with external screw thread, and is fixed on the upper mold mounting plate by nut.
The utility model is simple in structure, reasonable in design, steel pipe is undertaken in the aligning process by mould, when the patrix of mould rises, can steel pipe be mentioned by hoisting frame, cover has roller shell on the cross bar of hoisting frame, be convenient to steel pipe mobile at hoisting frame, in the aligning process, the power that can utilize forcing press to provide is mentioned steel pipe, steel pipe with patrix together about, be convenient to workman's operation, working (machining) efficiency is high.
Description of drawings:
Fig. 1 is structural representation of the present utility model.
The specific embodiment:
For technological means, creation characteristic that the utility model is realized, reach purpose and effect is easy to understand, below in conjunction with concrete diagram, further set forth the utility model.
As shown in Figure 1, a kind of lifting device of welded still pipe straightening die set, comprise mold mounting plate 1, upper mold mounting plate is equipped with patrix fixed mount 2 on 1 lower surface, and die body 3 is installed in patrix fixed mount 2 lower ends, is fixed with hoisting frame 4 on the upper mold mounting plate 1, hoisting frame 4 comprises that outer cover has the cross bar 43 of roller shell 42, cross bar 43 two ends are fixed on the upper mold mounting plate 1 by vertical pole 41, and vertical pole 41 upper ends are shaped with external screw thread, and are fixed on the upper mold mounting plate 1 by nut.
Above demonstration and described basic principle of the present utility model, principal character and advantage of the present utility model.The technical staff of the industry should understand; the utility model is not restricted to the described embodiments; that describes in above-described embodiment and the specification just illustrates principle of the present utility model; under the prerequisite that does not break away from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall in claimed the utility model scope.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
