Abstract
The utility model discloses a hydraulic pressure head shrinking machine, comprising a machine frame and a main frame which is installed on the machine frame, wherein the main frame is two pairs of opposite pressure hydraulic cylinders which are installed on the upper, lower, left and right part of the machine frame; the extended end of the piston rod of each hydraulic cylinder is connected with a work bench; each work bench is arranged with an opposite pressure mould; the front end of the left and right pair of moulds is 'W'-shaped. The head shrinking machine has the characters that the structure is assorted with the relative apparatus of the through-pipe production line, suitable for the pipeline operation of the steel tube production; the head shrinking machine is provided with fast head shrinking and good synchronism of the opposite pressure oil cylinder, adapted to the speed of the through-pipe and other requirements; the head shrinking machine constitutes one production line along with the through-pipe machine and the conveying appliance, which is provided with high production efficiency and high level of automation, improves the labor intensity and labor conditions of the workers and effectively advances the head shrinking quality of the pipe, which makes the mission success rate of the head shrinking enhanced; the utility model is provided with stable and reliable capability and convenient to be operated and maintained.
Description
Technical field:
The utility model relates to a kind of lathe, relates in particular to a kind of hydraulic pressure drop-head machine that the solid drawn tube technological process of production is finished the preceding drop-head operation of seamless steel pipe drawing that is used for.
Background technology:
At present, it is general just relatively backward to finish the steel pipe drop-head technology of using in the preceding drop-head technology of seamless steel pipe drawing in the solid drawn tube technological process of production, be mainly the unidirectional compacting of forcing press and combine with manually-operated, working strength is big, inefficiency, environment temperature height, condition of work very severe.The discontinuous operation in strange land of poling operation and drop-head operation in addition, temperature has reduced or has had little time drop-head and almost reduced to room temperature when making the high temperature pipe that gets off from poling machine to drop-head, pressure increases when causing drop-head, and easily producing stress concentrates, tube head very easily ruptures during drawing, must carry out the secondary drop-head of doing over again, thereby cause the waste of manpower and material.
Summary of the invention:
For addressing the above problem, it is fast that the purpose of this utility model provides a kind of drop-head speed, drop-head quality height, mechanization degree height, is suitable for the hydraulic pressure drop-head machine of seamless steel tube production pipelining.
The technical solution of the utility model realizes in the following manner:
A kind of hydraulic pressure drop-head machine, form by frame and rack-mounted main frame, wherein main frame be two pairs to the hydraulic fluid cylinder pressure, two pairs the hydraulic fluid cylinder pressure divided about, about be installed on the frame, the piston rod external part of each hydraulic cylinder connects a workbench, is equipped with the pressing mold tool on each workbench.
Fixing T-shape groove to the pressing mold tool is arranged on each workbench.
Each workbench both sides all is equipped with anti-rotation device, prevents the rotation of workbench in the compression process, guarantee relative hydraulic cylinder the worker advance and compression process in accurate matched moulds.
Two pairs coincide to the center line of hydraulic fluid cylinder pressure and the cross axis of frame.
Pair of right and left is " W " type to pressing mold tool front end.
The good effect of the technical solution of the utility model is:
The related facility of the design feature of this drop-head machine and poling production line is complementary, and is suitable for the pipelining of steel pipe's production; Drop-head speed is fast, synchronism to compressing cylinder is good, be adapted to speed and other requirement of poling fully, form a production line with poling machine, conveying device, production efficiency height, automaticity height, and can carry out far distance controlled, the workman only need controlling electric device cashier's office in a shop button get final product, improved working strength of workers and working condition fully.Because poling and drop-head operation are worked continuously, and steel pipe high temperature reduces drop-head power greatly, also eliminated the generation of stress simultaneously substantially in addition, improved the drop-head quality of pipe effectively, the success rate of drop-head is improved.Its performance highly stable reliable and handled easily and maintenance.
Description of drawings:
Fig. 1 is a structural representation of the present utility model.
The specific embodiment:
Below in conjunction with accompanying drawing the technical solution of the utility model is further described:
As shown in Figure 1, this hydraulic pressure drop-head machine is made up of frame 2 and the main frame that is installed on the frame 2, wherein, main frame be two pairs to hydraulic fluid cylinder pressure 1, two pairs to hydraulic fluid cylinder pressure 1 be separately fixed at frame 2 about, left and right directions, and the cross axis of the center line of hydraulic cylinder 1 and frame 2 coincides, four hydraulic cylinders 1 are the major impetus execution unit of this equipment, the piston rod external part of each hydraulic cylinder is connected with workbench 3, be processed with fixing T-shape groove to the pressing mold tool on each workbench 3, two pairs are separately fixed on the workbench 3 pressing mold tool (4,5); Be it can also be seen that by Fig. 1: pair of right and left mould front end is " W " type; For preventing the rotation of workbench 3 in the compression process, the anti-rotation device that prevents that workbench from rotating is all designed in every workbench 3 both sides, with guarantee relative hydraulic cylinder 1 the worker advance and compression process in accurate matched moulds.
Operation principle of the present utility model is: the work centre of drop-head machine is consistent with the center of transmitting device, the pipe that gets off from punch enters the drop-head machine through transmitting device, the operator only need operate control button, at first left and right sides hydraulic cylinder compresses relatively, " W " type that tube head is pressed into is return, and hydraulic cylinder flattens the drop-head operation of promptly finishing a steel pipe to pressing with it up and down then.
