Abstract
The invention belongs to the field of mechanical equipment, and discloses a tube drawing machine. The structure of the tube drawing machine is that: a main cylinder is connected with a drawing rod; a tension meter is arranged on the drawing rod; a tube drawing connection chuck is arranged on the bottom of the drawing rod. The upper end of a column used for adjusting height and fixing a workpiece is connected to a top fixed plane, and the lower end of the column is connected on an upper workbench. Machine body columns are connected with the top fixed plane through verticality adjusting apparatuses. A lower workbench and bottom trays are fixed on the machine body columns. Bottom adjusting bolts are arranged at the lower parts of the bottom trays. The tube drawing machine is advantaged in that: a digital-control hydraulic pump system is adopted, and the digital-display tension meter is adopted. Peak tensile forces can be accurately recorded. The tube drawing machine has a data storing function, such that a plurality of data can be stored in memory and can be printed and outputted. Therefore, recording is convenient, labor intensity is greatly reduced, and work accuracy is greatly improved.
Description
Technical field
The present invention relates to a kind of drawbench, belong to the plant equipment field.
Background technology
In the heat exchange equipment manufacture process, can often run into the situation of the expanded joint quality being carried out the pulling-out force test; Generally speaking, can select to adopt more indirect way, for example adopt the testing equipment of the tensile test of doing the physicochemical property test; Or adopt more original way such as press; More time-consuming accuracy is not high yet, and is relatively stricter for expanded joint power being required like: the heat exchanger of nuclear power of having relatively high expectations, adopts that old way is just more limited can not to reflect truly, accurately that pulling-out force is big or small; The reliability of workmanship can not be confirmed, can bring hidden danger to the nuclear power product.In addition, existing test is fixed with the tautness meter upper grip, cannot regulate, and need can not guarantee that whole pipes and chuck are concentric when a plurality of pipes carry out tensile test on the test specimen again, can accurately not measure pulling force.
Summary of the invention
In view of the defective that prior art exists, the purpose of this invention is to provide a kind of accurately, convenient, drawbench efficiently.
For realizing above-mentioned purpose; The technical solution that the present invention adopted mainly is: a kind of drawbench, and its structure comprises: master cylinder is connected with pull bar, and pull bar is provided with tautness meter; The bottom of pull bar is provided with tube drawing and connects dop; Regulate height and fixation workpiece and be connected on the stationary plane of top with the column upper end, the lower end is connected on the upper table, and the fuselage column is connected with the top stationary plane through the verticality regulating device; Lower table, bottom tray all are fixed on the fuselage column, are provided with the bottom below the bottom tray and regulate bolt.
Said tautness meter inside is equipped with sensor.
Said upper table, adjusting height and fixation workpiece can move with column.
A kind of drawbench; Its beneficial effect is: adopt the hydraulic pump system of Digital Control, the tautness meter that numeral shows can write down the peak value pulling force accurately; And has data storage function; Can numerous data storage can be derived and print output in internal memory, make things convenient for record, reduce labour intensity greatly and improve the work accuracy; Adopt moving bolster and transportable fixation workpiece to use column, can make the heat exchanger tube on the test specimen all keep concentric, avoided the inaccurate problem of bringing because of decentraction of test pulling force with the tautness meter dop.
Description of drawings
Fig. 1 is a kind of structure diagram of drawbench.
Fig. 1 Reference numeral is following: 1, master cylinder, 2, tautness meter, 3, tube drawing connects dop, 4, regulate height and fixation workpiece is used column; 5, fuselage column, 6, upper table, 7, lower table; 8, verticality regulating device, 9, the bottom regulates bolt, 10, bottom tray; 11, top stationary plane, 12, pull bar, 13, sensor.
Embodiment
According to Fig. 1 a kind of drawbench is further specified below:
Master cylinder 1 is connected with pull bar 12, connects hydraulic pump system and control system behind the master cylinder 1; Pull bar 12 is provided with tautness meter 2, and its inside is equipped with sensor 13, through sensor 13 data transmission is arrived controller, and at the controller video data, controller has memory function, can these data be derived through data line and print; The bottom of pull bar 12 is provided with tube drawing and connects dop 3; Regulating height and fixation workpiece is connected on the stationary plane of top with column 4 upper ends; The lower end is connected on the upper table 6, and said upper table 6 bottoms have roller, regulates the relative position that is drawn workpiece; Make each drawn workpiece coaxial, guarantee that the pulling force that records is accurate with master cylinder motion stops center; Fuselage column 5 is connected with top stationary plane 11 through verticality regulating device 8, can regulate the verticality of master cylinder piston and work top; Lower table 7, bottom tray 10 are fixed on the fuselage column 5, are provided with the bottom below the bottom tray 10 and regulate bolt 9, regulate the levelness of bolt 9 scalable bottom tray through regulating the bottom.
