Description
Technical field:
The present invention relates to steel pipe manufacturing industry field of mechanical technique, specifically a kind of pipe electric spark centring machine with outside centering clamping device.
Background technology:
Existing pipe electric spark centring machine is made up of charging gear, support roller device, main machine base, main frame elevating mechanism, large walking mechanism, little walking mechanism, eccentric rotation mechanism, electrode assembly, drag chain, Arc Welding Power; Pipe is transplanted on centering station support roller device by charging gear; Electric spark centring machine main frame is installed on main machine base; Main frame elevating mechanism realizes the centering of carbon-point and pipe; Large walking mechanism drives carbon-point to arrive Working position fast, and fast fallback, to initial position, improves the service efficiency of equipment; Little walking mechanism drives carbon-point to advance and retreats, and realizes the striking of carbon-point, feeding processing and detect carbon-point whether loss is complete; Electrode assembly clamping carbon-point, introduces carbon-point by positive source; The corresponding source of welding current of Arc Welding Power supply centering apparatus realizes striking and pipe punching; Eccentric rotation mechanism drives electrode assembly to carry out circular motion, coordinates little walking mechanism to drive carbon-point to carry out screwfeed campaign, thus realizes the effect increasing processing aperture; Drag chain protection cable and pneumatic line; The subject matter that prior art exists:
1, subsidiary engine part does not have hydraulic floating clamping device, and support roller device can not be elevated, and main frame is provided with elevating mechanism; According to the steel billet of centering different size, regulated the position in vertical direction, carbon-point center of centring machine by main frame elevating mechanism, thus carbon-point center line is overlapped with pipe center line, realize centering object;
2, because height of main frame adjustment relies on elevating mechanism both sides guide pillar to keep main frame balance, walking mechanism is advanced, backward movement can cause the stability of main frame slightly poor, causing the centering effect of carbon-point and pipe not ideal enough, there is error in the axiality of pipe end face internal point;
3, owing to lacking hydraulic floating clamping device, when pipe axial bending degree is comparatively large or end face ovality is larger, the centering effect of carbon-point and pipe can be badly influenced, cause the coaxiality error of pipe end face internal point larger, the inclined wall of pierced shell pipe end, has influence on product lumber recovery.
summary of the invention:
The object of the invention is the deficiency overcoming above-mentioned prior art, and a kind of pipe electric spark centring machine with outside centering clamping device is provided, mainly solve the centering problem of pipe electric spark centring machine carbon-point center line and pipe center line.
Technical scheme of the present invention is: a kind of pipe electric spark centring machine with outside centering clamping device, be made up of main and auxiliaries two parts, its special character is, described main frame is by main machine base, large walking mechanism, little walking mechanism, eccentric rotation mechanism, electrode assembly, Arc Welding Power forms, main machine base is established large walking mechanism, large walking mechanism establishes little walking mechanism, drag chain is provided with between little walking mechanism and main machine base, eccentric rotation mechanism is established in little walking mechanism front end, eccentric rotation mechanism establishes electrode assembly, carbon-point installed by electrode assembly, Arc Welding Power cable is connected with electrode assembly by drag chain, described subsidiary engine is made up of charging gear, lifting carrier roller device, hydraulic floating clamping device, establishes lifting carrier roller device between charging gear and hydraulic floating clamping device, and hydraulic floating clamping device is corresponding with the electrode assembly of main frame.
Compared with the prior art a kind of pipe electric spark centring machine with outside centering clamping device of the present invention has outstanding substantive distinguishing features and marked improvement, 1, host machine part eliminates main frame elevating mechanism, subsidiary engine support roller device adopts lifting carrier roller device, carbon-point position of center line is constant, by adjustment support roller device height, pipe center line is overlapped with carbon-point center line, both improve the stability of main frame, in turn ensure that the centering effect of carbon-point and pipe; 2, subsidiary engine part adds hydraulic floating clamping device, when pipe axial bending degree is comparatively large or end face ovality is larger, effectively can be ensured the centering effect of pipe and carbon-point by hydraulic floating clamping device clamping blank end, guarantee that the axiality of pipe end face internal point is in error allowed band; 3, improve pierced shell quality tips, improve product lumber recovery.
Accompanying drawing illustrates:
Fig. 1 is structural representation of the present invention.
Wherein, 1 centring tube base 2, charging gear 3, lifting carrier roller device 4, hydraulic floating clamping device 5, carbon-point 6, electrode assembly 7, eccentric rotation mechanism 8, little walking mechanism 9, large walking mechanism 10, main machine base 11, drag chain 12, Arc Welding Power, is treated.
Detailed description of the invention:
In order to Comprehension and Implementation better, provide specific embodiment below in conjunction with accompanying drawing and describe the present invention in detail; Illustrated embodiment, only for explaining the present invention, is not for limiting the scope of the invention.
Embodiment 1, see Fig. 1, need to be processed into main machine base 10 according to design, main machine base 10 is installed large walking mechanism 9, large walking mechanism 9 installs little walking mechanism 8, between little walking mechanism 8 and main machine base 10, drag chain 11 is installed, at little walking mechanism 8 front end setting-up eccentricity rotation mechanism 7, installing electrodes device 6 on eccentric rotation mechanism 7, electrode assembly 6 is installed carbon-point 5, Arc Welding Power 12 cable is connected with electrode assembly 6 by drag chain 11, forms host machine part of the present invention; Subsidiary engine part, lifting carrier roller device 3, hydraulic floating clamping device 4 are installed below at charging gear 2, hydraulic floating clamping device 4 is corresponding with the electrode assembly 6 of main frame, treats that centring tube base 1 is realized and carbon-point 5 centering by lifting carrier roller device 3, hydraulic floating clamping device 4.
A kind of pipe electric spark centring machine with outside centering clamping device of the present invention, during work, charging gear will treat that centring tube base is transplanted on centering station lifting carrier roller device, by adjustment lifting carrier roller device height, pipe center line is overlapped with carbon-point center line, the centering effect of blank end and carbon-point is guaranteed in hydraulic floating clamping device clamping.After steel billet centering, large walking mechanism drives carbon-point to be fast-forward to steel billet end face to increase work efficiency, and the advance of little walking mechanism drive carbon-point is flipped steel billet and carried out striking; Electrode assembly clamping carbon-point, introduces carbon-point by positive source; The corresponding source of welding current of Arc Welding Power supply centering apparatus realizes striking and pipe punching; Eccentric rotation mechanism drives electrode assembly to carry out circular motion, coordinates little walking mechanism to drive carbon-point to carry out screwfeed campaign, thus realizes the effect increasing processing aperture; After reaching working depth, large walking mechanism and little walking mechanism rewind, machine.Effectively be ensure that the centering effect of pipe and carbon-point by lifting carrier roller device and hydraulic floating clamping device, ensure that the axiality of pipe end face internal point, improve pierced shell quality tips, improve product lumber recovery.
