The specific embodiment
Shown in Fig. 1~5, be combined into set of molds 3 by three molds, mould is upper and lower two halves opening-closing structure, every mold is provided with die cavity 3.1, set of molds is installed in half groove that front apron 1 and backboard 2 and base plate 9 constituted with sliding mode, be connected with set of molds cylinder displacement 7 in set of molds one side, be provided with upsetting squeeze oil cylinder 8 at the position of the corresponding die cavity in the front side of set of molds.Binding clasp 4 is a two halves opening-closing structure up and down, is divided into binding clasp upper plate 4.1 and binding clasp lower plate 4.2.On upper mold half and binding clasp upper plate, be connected with mould open/close oil cylinder 6 and binding clasp oil cylinder 5 respectively.Position at the corresponding die cavity in the front side of set of molds is provided with upsetting squeeze oil cylinder 8.
By oil compression rod sealing ring 7.2 oil compression rod 7.1 is installed in the set of molds cylinder displacement 7, its end is provided with oil compression rod connecting plate 7.3, is being provided with hydraulic fluid port 7.4 and following hydraulic fluid port 7.5 on the set of molds cylinder displacement.
Be connected with oil pump 10 by pipeline with following hydraulic fluid port at last hydraulic fluid port, between oil pump and last hydraulic fluid port, be connected with hydraulic oil quantitative controller 11.
The hydraulic oil quantitative controller is made of left oil circuit valve 11.1, left oil compression rod 11.11, the quantitative oil hydraulic cylinder 11.12 in a left side and right oil circuit valve 11.2, right oil compression rod 11.21 and right oil hydraulic cylinder 11.22.
The work of machine for processing and squeezing of the present invention and use
Pass between the upper and lower plates of binding clasp through three rod workpiece of high-frequency heating and the going up between second and outside die cavity, leave and reserve section of mould, start binding clasp oil cylinder and mould open/close oil cylinder, workpiece is clamped the also die cavity of closed die, operation set of molds cylinder displacement makes the pre-upsetting squeeze part of first station aim at the upsetting squeeze oil cylinder, starting the upsetting squeeze oil cylinder simultaneously pushes the section of reservation in die cavity, be filled in the die cavity, finish upsetting squeeze for the first time.After the first time, upsetting squeeze was finished, regain the oil compression rod of upsetting squeeze oil cylinder, drive clamping cylinder, mould is opened, drive clamping cylinder simultaneously binding clasp is opened, drive the set of molds cylinder displacement then and carry out set of molds and move, make former second station shift the first station position onto through the workpiece of pre-upsetting squeeze, drive the mould open/close oil cylinder and make mould closes, drive clamping cylinder binding clasp is clamped, restart the work of upsetting squeeze oil cylinder, workpiece is carried out the upsetting squeeze second time.After finishing upsetting squeeze for the second time, drive the mould open/close oil cylinder, open mould, drive clamping cylinder, binding clasp is unclamped, the hydraulic stem that drives the set of molds cylinder displacement again moves to the first station position with the workpiece of former the 3rd station, carries out upsetting squeeze for the third time.Through having finished the process of workpiece upsetting squeeze overstriking after three upsetting squeezes, drive mould open/close oil cylinder and binding clasp oil cylinder, open mould and binding clasp, take out workpiece, the upsetting squeeze of finishing a sucker rod adds roughing.
After the upsetting squeeze of finishing a sucker rod adds roughing, if proceed the jumping-up processing of sucker rod, then start the set of molds cylinder displacement, hydraulic stem is withdrawn in the oil cylinder, simultaneously first station of set of molds is aimed at the position of upsetting squeeze oil cylinder, continued the upsetting squeeze sucker rod.
The action of set of molds cylinder displacement realizes by the hydraulic oil quantitative controller.Before the use, at first open left oil circuit valve and right oil circuit valve, start the oil pump running, the oil of cylinder cavity front end is extracted and is drained into by following hydraulic fluid port out the rear end of oil compression rod sealing ring by last hydraulic fluid port, make oil compression rod return to initial position, close left oil circuit valve and right oil circuit valve.At this moment, oil compression rod connecting plate pulling set of molds makes first station aim at the upsetting squeeze oil cylinder, carries out the upsetting squeeze operation.After finishing the operation of upsetting squeeze for the first time, depress left oil compression rod, the hydraulic oil in the quantitative oil hydraulic cylinder in a left side is drained in the oil cylinder by last hydraulic fluid port, promote oil compression rod and move a station backward, the mould of second station that drives set of molds simultaneously carries out the upsetting squeeze second time to the first station position.Row is depressed right oil compression rod to the anterior oiling of oil cylinder again, promotes oil compression rod and moves backward, carries out upsetting squeeze for the third time.Through three upsetting squeezes, the upsetting squeeze of finishing a sucker rod adds roughing.
Because quantitatively oil hydraulic cylinder is realized quantitatively oiling in cylinder displacement, so can make the hydraulic stem fixed length promote the set of molds displacement, make the mould contraposition fast, accurately, improved the processing effect.
Because the mould installation position of The manufacturing approach of pump plunger of the present invention is provided with set of molds, a set of molds is provided with three die cavitys, so can realize continuous upsetting squeeze operation.
Because when the sucker rod of a station of upsetting squeeze, two stations carry out the pan feeding clamping preparatory stage in addition.When the sucker rod of a station is finished upsetting squeeze, start cylinder displacement promotion set of molds and move and form new processing stations to next station, the upsetting squeeze oil cylinder carries out upsetting squeeze to the oil pumping rod end once more.So constantly the conversion station carries out the upsetting squeeze operation of sucker rod.So the upsetting squeeze oil cylinder is in continuous duty, do not wait for the pan feeding time, and divide three progressively upsetting squeezes, improve 3~5 times of upsetting squeeze speed.Output and working ability have been increased, so reduced the consumption of the production cost and the energy.
