Description
Technical field
The invention belongs to technical fields of mechanical processing, and in particular to a kind of device for thickening 5 cun of oil drill rocker pipe ends.
Background technique
When carrying out 5 cun of drill rocker end upsettings, the technique used is to heat to form three times three times, only two for company at present
In the case where covering two press machines of heating equipment, it cannot be continuously finished the thickening molding of three passages, need first to carry out to add for the first time
Heat thickeies, and then replaces the heating thickening that tooling carries out second and third passage.The disadvantage is that replacement tooling is frequent, low efficiency, the energy disappears
Consumption is big.
Summary of the invention
The purpose of the present invention is to provide a kind of devices for thickening 5 cun of oil drill rocker pipe ends.The present invention can effectively make stone
Oily drill rod pipe end jumping-up, solve existing 5 cun of drill rod pipe end jumping-ups when replacement tooling frequently, low efficiency, the big problem of energy consumption.
The technical solution adopted by the present invention: a kind of device thickening 5 cun of oil drill rocker pipe ends, it includes drill pipe body, adds
Thick die sleeve and formed punch, the thickening die sleeve inside is through-hole, thickeies the annular for being provided on the outer wall of die sleeve and clamping for thickening machine
The inner wall internal diameter of groove, the through-hole gradually narrows in the middle part of through-hole to from the aperture of side, and close to the side opening mouth in through-hole
It is provided with one section of small straightway on inner wall, is provided with one section of big straight line on the inner wall in through-hole other side aperture in through-hole
What the small diameter portion light splitting slip that section, small straightway and through-hole wall gradually narrow, big straightway and through-hole wall gradually narrowed
Large diameter portion is smoothly connected, and the outer diameter of the internal diameter of straightway and drill pipe body is interference fitted in through-hole；The formed punch is single order
The trapezoidal body of rod is formed from being successively integrally formed to the right side by the front end body of rod, middle part apical grafting flange, the rear portion body of rod and clamping part greatly,
Wherein, clamping part is mounted on the flange of press cross cylinder, and the front end body of rod passes through the inner hole of drill pipe body, and the front end body of rod
The internal diameter of diameter and drill pipe body interference fit, middle part apical grafting flange outside diameter is identical as the diameter of through-hole wall large diameter portion, and
Middle part apical grafting flange and drill pipe body, which protrude into, is thickening one end outer rim apical grafting in die sleeve through-hole, pushes drill pipe body to Forward
Dynamic, rear portion shank diameter is less than the diameter of middle part apical grafting flange.
Further, the overall length of the front end body of rod of the formed punch, middle part apical grafting flange and the rear portion body of rod is greater than thickening model
Cover the length of through-hole.
The present invention compared with prior art the beneficial effect is that: the present invention by setting one with drill pipe body thicken shape one
The thickening die sleeve of sample makes drill pipe body thicken hot compression deformation in die sleeve by hydraulic punching head.The configuration of the present invention is simple reduces
Cost of the drill pipe body in end upsetting.
Detailed description of the invention
Fig. 1 is the structural diagram of the present invention.
Specific embodiment
It should be noted that in the absence of conflict, the features in the embodiments and the embodiments of the present application can phase
Mutually combination.The present invention will be described in detail below with reference to the accompanying drawings and embodiments.
