Abstract
The invention relates to a handrail end circular arc punching and forming device. The handrail end circular arc punching and forming device comprises an upper die seat, a lower die seat and a circular arc punching mechanism installed between the upper die seat and the lower die seat, wherein the circular arc punching mechanism consists of a male die, a supporting female die, a male die fixing plate and a supporting die core, the male die fixing plate provided with the male die is arranged on the upper die seat, the supporting die core is installed on the lower die seat, the male die is vertically arranged above the supporting die core, the supporting female die is fixedly arranged under the supporting die core, and the supporting female die and the male die are located on the same vertical line. A die is convenient to manufacture and maintain and compact in structure, the design work can be greatly simplified, a design period is shortened, and the cutter design and manufacture cost is reduced.
Description
Technical field
The present invention relates to a kind of thin-wall steel tube blanking units, is a kind of railing termination circular arc punching and shaping device specifically.
Background technology
In light industry product, extensively adopt tubing as part, support, the junction surface of tube and tube needs pipe end is processed into to the arc opening curved surface before welding, make the tube and tube welding that can coincide, adopted milling, grinder buffing, gas cutting pipe end to complete the pipe nock in the past, this processing method work efficiency is low, and quality stability is poor.Cutting and lubricating oil also can pollute tube wall, before welding, need to clean, and the oxygen-acetylene gas cutting is shaped bad, and grinder buffing splashes, and has potential safety hazard, also can affect the workman healthy.
Summary of the invention
Technical problem to be solved by this invention is, overcomes the shortcoming of prior art, and a kind of railing termination circular arc punching and shaping device is provided, and utilizes mould to carry out the blanking of circular pipe termination, solves the problem of tubing termination distortion.
In order to solve above technical problem, the invention provides a kind of railing termination circular arc punching and shaping device, comprise upper bolster, die shoe and be arranged on the circular arc punching mechanism between described upper bolster and die shoe, described circular arc punching mechanism is by punch, the retainer die, punch retainer and carrying mold cores form, the described punch retainer that punch is installed is arranged on described upper bolster, described carrying mold cores is arranged on die shoe, described punch is arranged vertically above described carrying mold cores, the below of described carrying mold cores is fixedly installed described retainer die, and described retainer die and punch are on same vertical line.
The technical scheme that the present invention further limits is: aforesaid railing termination circular arc punching and shaping device, on described carrying mold cores, also be provided with a grade part plate, and the position in order to die-cut mouthful of control group rod tube spare, guarantee die-cut accuracy.
Further, aforesaid railing termination circular arc punching and shaping device, the front end of described carrying mold cores is provided with circular chamfering, and being convenient to pipe fitting can insert in carrying mold cores smoothly.
The invention has the beneficial effects as follows: the present invention has following characteristics: (1) pipe end nock utilizes the mould clicking technique to replace Milling Process, for wall thickness, is that the section face nock clicking technique of the thin-walled hollow steel pipe of 1～3.5mm is all feasible; (2) the mould manufacture is easy to maintenance, the mould features compact structure.Simplified design work greatly, shorten the design cycle, reduces Tool Design and manufacturing expense; (3) mould, when guaranteeing the pipe nock degree of depth, only needs to adjust a mould nock depth localization piece and carry out controlling dimension, has guaranteed the tube and tube welding quality of coincideing.
The accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Fig. 2 is carrying mold cores structural representation of the present invention.
Fig. 3 is the A-A cutaway view of Fig. 2.
Fig. 4 is the B-B cutaway view of Fig. 2.
The specific embodiment
The present embodiment provides a kind of railing termination circular arc punching and shaping device, as shown in Figures 1 to 4, comprise upper bolster 1, die shoe 2 and be arranged on upper bolster and die shoe between the circular arc punching mechanism, the circular arc punching mechanism is comprised of punch 3, retainer die 4, punch retainer 5 and carrying mold cores 6, the punch retainer 5 that punch is installed is arranged on upper bolster 1, carrying mold cores 6 is arranged on die shoe, punch 3 is arranged vertically above carrying mold cores, the below of carrying mold cores is fixedly installed retainer die 4, and retainer die 4 is on same vertical line with punch 3; On carrying mold cores, also be provided with a grade part plate 7, the position in order to die-cut mouthful of control group rod tube spare, guarantee die-cut accuracy.
The pipe end nock adopts carrying mold cores and the cutting knife cutting edge of holding concurrently carries out Punching Technology, the end face nock clicking technique that to wall thickness is the thin-walled hollow steel pipe of 1 ~ 3.5mm is feasible, after pipe retainer die trip bolt is tightened, carrying mold cores abuts on pipe retainer die, tubing just is stuck in pipe retainer concave template, pipe retainer concave template is to its fixation of tubing, and also just there is constraint in the change in shape trend under the flush shear force effect to the tubing cross section.
In addition to the implementation, the present invention can also have other embodiments.All employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop on the protection domain of requirement of the present invention.
