Abstract
The utility model discloses a fixed type steel cylinder trimmer, comprising a rack, a hydraulic means, an upper die, a lower die, a slide block and a slideway. The lower die is fixedly disposed at the bottom of the rack, and the hydraulic means is fixedly disposed at the top of the rack. The upper die is connected to an output end of the hydraulic means through the slide block, and the slide block is in a sliding fit with the slideway of the rack. The upper die and the lower die is buckled together, forming a circular hollow cavity. The inner concave surface of the lower die is provided with a telescopic support ball. The fixed type steel cylinder trimmer is advantageous in that the steel cylinder disposed on the lower die will not move at the time of extruding, and thereby shaping of the steel cylinder can be completed by one shot; manpower and material resources are reduced, and production cost is saved.
Description
Technical field
The utility model relates to a kind of steel trimmer, relates in particular to a kind of fixed steel cylinder trimmer.
Background technology
Steel cylinder is used comparatively extensive in broadcasting television tower, communications tower, electric power steel pipe iron tower and petroleum pipeline, to the requirement of its shape and accuracy than higher.Existing finely finishing method generally adopts simple tools such as jack, gas welding to carry out artificial finishing.There is that production efficiency is low, production cost is high, assembly precision is low, working strength of workers is high and the shortcoming of shaping effect difference.
In order to address the above problem, following patented technology has been proposed in the prior art:
China Patent No. " 201120129695.5 " discloses a kind of multi-functional steel cylinder trimmer, and its open day is on October 26th, 2011.Its technical scheme comprises frame, hydraulic means, mold, bed die, slide block, slideway, bed die is fixedly installed on the frame bottom, hydraulic means is fixedly installed on frame top, mold is connected with the output of hydraulic means by slide block, the slideway of slide block and frame is slidingly matched, hydraulic means is the double-cylinder hydraulic device, and described mold, bed die all are dies, and the cavity shape after mold, bed die fasten is circle, ellipse or polygon.
But be the prior art of representative with above-mentioned patent document, in actual use, because steel cylinder is columniform, and there is not bracing or strutting arrangement on the bed die, needing many people to control steel cylinder during extruding could be to its shaping, not only the wasting manpower and material resources also can cause the shaping of steel cylinder not thorough, needs repeatedly shaping just can reach the shaping standard.
Summary of the invention
The purpose of this utility model is to solve the problems referred to above that the steel cylinder trimmer exists in the prior art, a kind of fixed steel cylinder trimmer is provided, after adopting the utility model, the steel cylinder that is placed on during extruding on the bed die can not be subjected to displacement, the disposable shaping that can finish steel cylinder, reduce manpower and materials, saved production cost.
For achieving the above object, the technical solution adopted in the utility model is as follows:
A kind of fixed steel cylinder trimmer, comprise frame, hydraulic means, mold, bed die, slide block and slideway, bed die is fixedly installed on the frame bottom, hydraulic means is fixedly installed on frame top, mold is connected with the output of hydraulic means by slide block, the slideway of slide block and frame is slidingly matched, and the cavity after mold and bed die fasten is circular, and it is characterized in that: the inner concave of described bed die is provided with the retractable supports ball.
The quantity of described retractable supports ball is a plurality of, is symmetricly set on two ends and the middle part of bed die upper edge.
Described bed die inner concave is provided with spacing hole, and described retractable supports ball is movably set in the spacing hole, and the diameter of retractable supports ball is greater than the spacing hole aperture.
Adopt advantage of the present utility model to be:
One, compares for the prior art of representative with China Patent No. " 201120129695.5 ", the inner concave of the described bed die of the utility model is provided with the retractable supports ball, after steel cylinder is placed on the bed die, the retractable supports ball plays a supportive role to the outer surface of steel cylinder, steel cylinder can not be shifted during extruding, also no longer need manually to control steel cylinder, disposablely just can finish the steel cylinder shaping, significantly improved shaping efficient.
Two, in the utility model, the quantity of described retractable supports ball is a plurality of, is symmetricly set on two ends and the middle part of bed die upper edge, and this arranges further spacing to steel cylinder, prevents that steel cylinder is shifted, and makes the support of steel cylinder more firm.
Three, in the utility model, described bed die inner concave is provided with spacing hole, and described retractable supports ball is movably set in the spacing hole, and the diameter of retractable supports ball is greater than the spacing hole aperture, before extruding, the retractable supports ball supports steel cylinder, prevents that steel cylinder is shifted, during extruding, increase along with pressure, in the retractable supports ball withdrawal spacing hole, contact with the inner concave of bed die until the surface of steel cylinder, simple and practical.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is left TV structure schematic diagram of the present utility model.
Be labeled as among the figure: 1, mold, 2, bed die, 3, slide block, 4, slideway, 5, frame, 6, hydraulic means, 7, the retractable supports ball.
The specific embodiment
A kind of fixed steel cylinder trimmer, comprise frame 5, hydraulic means 6, mold 1, bed die 2, slide block 3 and slideway 4, bed die 2 is fixedly installed on frame 5 bottoms, hydraulic means 6 is fixedly installed on frame 5 tops, mold 1 is connected with the output of hydraulic means 6 by slide block 3, slide block 3 is slidingly matched with the slideway 4 of frame 5, and the cavity after mold 1 fastens with bed die 2 is circular, and the inner concave of described bed die 2 is provided with retractable supports ball 7.
Further, the cavity after mold 1 fastens with bed die 2 also can ellipse or polygon etc.
Preferred embodiment of the present utility model is, the quantity of described retractable supports ball 7 is a plurality of, be symmetricly set on two ends and the middle part of bed die 2 upper edges, but be not limited to above-mentioned set-up mode, retractable supports ball 7 can be arranged on the arbitrary position of bed die 2 inner surfaces.
Another preferred embodiment of the present utility model is, described bed die 2 inner concaves are provided with spacing hole, described retractable supports ball 7 is movably set in the spacing hole, the diameter of retractable supports ball 7 is greater than the spacing hole aperture, but be not limited to above-mentioned set-up mode, retractable supports ball 7 also can adopt stretch mode commonly known in the art, and fulcrum ball also can be by replacements such as support columns.
Another preferred embodiment of the present utility model is, described mold 1 is fixedlyed connected with the output of hydraulic means 6 by bolt, and described bed die 2 is fixedlyed connected with frame 5 bottoms by bolt.
Operation principle of the present utility model is: at first use row to hang and will treat that the shaping steel cylinder transfers in the bed die 2, the retractable supports ball 7 that the middle part is gone at two ends, bed die 2 inner concave upper edge supports steel cylinder, prevent that it is shifted, hydraulic means 6 drives mold 1, mold 1 moves to bed die 2 under the cooperation of slideway 4 and slide block 3, when mold 1 contacts with bed die 2 when coincideing, retractable supports ball 7 is also withdrawn under the effect of pressure in the spacing hole, treat steel cylinder be extruded smooth after, mold 1 resets under the drive of hydraulic means 6, takes out the steel cylinder after smooth.
