Abstract
The utility model relates to a pre-finishing welded arc striking and extinguishing plate making device, which comprises a hydraulic press and a die, wherein the die comprises an upper die, an adjusting screw and two symmetrical bases; the bottom of the upper die is arc-shaped, and the upper die is arranged at the bottom of an upper pressure head workbench of the hydraulic press; inverse T-shaped guide grooves are formed in the surface of a lower workbench of the hydraulic press; the two bases are arranged on the lower workbench of the hydraulic press through T-shaped bolts; the T-shaped bolts are arranged in the inverse T-shaped guide grooves; the two bases are connected through the adjusting screw; and a positioning nut is arranged at each of two ends of the adjusting screw. The pre-finishing welded arc striking and extinguishing plate making device is suitable for making an arc striking and extinguishing plate in a pre-finishing welded spiral submerged arc welded pipe production technology, the device is reasonable in structure, and the radian nearby by the arc vertex of the arc striking and extinguishing plate made by using the device can be kept in accordance with the radian of a steel pipe; the die is adjustable, and arc striking and extinguishing plates with different sizes can be made by adjusting the die to adapt to steel pipes with different sizes; and the device is wide in application range and suitable for large-scale popularization and use.
Description
Technical field
The utility model relates to a kind of astute and able blow-out plate producing device that draws in advance, is applicable to that the blow-out plate that draws in the preparatory astute and able spiral submerged welded pipe production technology is made.
Background technology
Preparatory astute and able spiral submerged welded pipe traditional production process is to adopt two-step method production, and promptly moulding prewelding and astute and able substep carry out, and like this, before astute and able, must draw the blow-out plate in the welding of steel pipe two ends.In order to reach the higher blow-out plate welding quality of drawing, the radian of radian and steel pipe that draws the blow-out plate is preferably in full accord.But because the influence of moulding residual stress, the arc that cuts down from enemy's pipe has strain, therefore; This arc can not directly be welded on the steel pipe; Must adopt method for processing to eliminate the residual stress of arc, the arc requirement that arc can be reached draw the blow-out plate, but present processing method more complicated; And the radian that draws the blow-out plate that processes is difficult to reach consistent with the radian of steel pipe, and effect is bad.
The utility model content
According to above deficiency of the prior art, the technical problem that the utility model will solve is: a kind of rational in infrastructure, preparatory astute and able blow-out plate producing device that draws that near draw the blow-out plate circular arc summit radian and steel pipe radian are consistent is provided.
The utility model solves the technical scheme that its technical problem adopted: the described astute and able blow-out plate producing device that draws in advance; It is characterized in that: comprise hydraulic press and mould, mould comprises patrix, adjusting screw(rod) and two symmetrically arranged bases, and the bottom of patrix is a circular arc; Patrix is installed in the bottom of hydraulic press seaming chuck workbench; The table top of hydraulic press lower table is provided with the inverted T shape guide groove, and two bases are installed on the lower table of hydraulic press through T type bolt, and T type bolt is arranged in the inverted T shape guide groove; Connect the two ends installing and locating nut of adjusting screw(rod) between two bases through adjusting screw(rod).
Because producing the required blow-out plate that draws of steel pipe (caliber or wall thickness are different) of different size varies in size; Therefore, before the blow-out plate is drawn in making, confirm to draw the blank size of blow-out plate blank according to producing cast earlier; Fix according to the distance between these size adjusting two bases (can realize adjusting) and with base then position base through regulating the position of T type bolt in the inverted T shape guide groove; Simultaneously adjusting screw(rod) is adjusted to the appropriate location,, will draw afterwards on two bases that blow-out plate blank is placed on mould then with setscrew nut location; Start hydraulic press; Adjustment patrix volume under pressure begins to press down, and the radian and the radian of steel pipe that draw near the blow-out plate circular arc summit that make are consistent.
Press down when drawing blow-out plate blank through patrix, blank can rub with the inboard of two bases, the long-time use; Base is easy to wear and tear; In order to prevent the base wearing and tearing, adopt following preferred version: in two base inside top the circular arc seat is set, places rotating shaft in the circular arc seat.
The beneficial effect that the utility model had is:
This is in advance astute and able, and to draw blow-out plate producing device rational in infrastructure, and near the radian that draws the blow-out plate circular arc summit that makes through this device can be consistent with the steel pipe radian; Mould has adjustability, draws the blow-out plate through what regulate that mould can make different size, and to adapt to the steel pipe of different size, applied range is fit to large-scale promotion and uses.
Description of drawings
Fig. 1 is the structural representation of the utility model;
Fig. 2 is the left view of Fig. 1.
Among the figure: 1, hydraulic press; 2, seaming chuck workbench; 3, patrix; 4, draw blow-out plate blank; 5, rotating shaft; 6, setscrew nut; 7, adjusting screw(rod); 8, base; 9, lower table; 10, hold-down nut; 11, T type bolt.
The specific embodiment
Below in conjunction with accompanying drawing the embodiment of the utility model is done and to further describe:
Like Fig. 1, shown in 2, the astute and able blow-out plate producing device that draws comprises hydraulic press 1 and mould in advance; Mould comprises patrix 3, adjusting screw(rod) 7 and two symmetrically arranged bases 8, and the bottom of patrix 3 is a circular arc, and patrix 3 is installed in the bottom of hydraulic press seaming chuck workbench 2; The table top of hydraulic press lower table 9 is provided with the inverted T shape guide groove, and two bases 8 are installed in through T type bolt 11 on the lower table 9 of hydraulic press, and T type bolt 11 is arranged in the inverted T shape guide groove; Connect through adjusting screw(rod) 7 between two bases 8; The two ends installing and locating nut 6 of adjusting screw(rod) 7 is provided with the circular arc seat in two bases, 8 inside top, places rotating shaft 5 in the circular arc seat.
When the blow-out plate is drawn in making, confirm to draw the blank size of blow-out plate blank according to producing cast earlier, then according to the distance between these size adjusting two bases 8; During adjusting, earlier the hold-down nut 10 of firm banking 8 is unscrewed, then movable base 8 and fixing with hold-down nut 10; When regulating two bases, 8 spacings, adjusting screw(rod) 7 is adjusted to appropriate location and screwed in place nut 6, will draw afterwards on two bases 8 that blow-out plate blank is placed on mould; Start hydraulic press; Adjustment patrix 3 volumes under pressure begin to press down, and the radian that draws near radian in blow-out plate circular arc summit and steel pipe that makes is consistent gets final product.
