Description

Large-scale digit-controlled hydraulic pressure straightener main frame

Technical field

The present invention relates to a kind of hydraulic press that is used for metallurgy industry, especially a kind of large-scale digit-controlled hydraulic pressure straightener main frame.

Background technology

Plug is to produce tandem rolling pipe important process equipment, and plug need carry out alignment before processing, so that reduce processing capacity.High more its machining amount of linearity is just few more, and stock utilization is just high more, and manufacturing cost is just low more.Cold school can be at room temperature carried out in the alignment of plug, also can carry out hot school under 350 ℃ of states.Domestic alignment process to plug mainly adopts common four-column hydraulic press at present, its structure is: two V-type seats that can support plug are installed on the workbench of common four-column hydraulic press, each V-type seat has simple manually spacing adjusting screw(rod), and anvil on the V-type is being installed on the slide block.Though common four-column hydraulic press can solve the alignment work of plug, but its workbench width is little, limited the bigger plug alignment processing of compacting diameter, and in whole operation, need to operate by manual measurement, location, automaticity is low, and alignment process efficient is low, the problem of low precision thereby cause; Traditional in addition straightener is not having under the workpiece situation, and the easily last pressure excess of stroke of master cylinder causes the destruction to fuselage.

Summary of the invention

The present invention for solve the technical problem that exists in the known technology provide a kind of automaticity high, that be applicable to thick school and smart school, have a large-scale digit-controlled hydraulic pressure straightener main frame that prevents master cylinder excess of stroke function.

The technical scheme that the present invention takes for the technical problem that exists in the solution known technology is:

A kind of large-scale digit-controlled hydraulic pressure straightener main frame, by sill, be installed in four columns on the sill, be installed in four columns upper ends entablature, be installed in the slide block that moves up and down on the column, the master cylinder that is installed in the driving slide block movement on the entablature and both sides piston type kicker cylinder, be installed in the V-type seat of two holding workpieces of sill upper surface, the electric operation platform that is installed in anvil on the V-type that presses down workpiece of slide block lower end and main control system operation is formed, described sill is a rectangle; It is guide upright post that two corner posts are arranged in described four columns; Described slide block is to be movably arranged on two slide blocks on the diagonal angle guide upright post; Each V-type seat of described holding workpieces, both sides are separately installed with fixed support, are horizontally installed with the leading screw that is threaded with the V-type seat on the fixed support and drive the reductor that leading screw rotates; The protective device that prevents to press on the master cylinder excess of stroke also is installed on the described slide block; The laser aligning checkout gear also is installed in the described sill.

The present invention can also adopt following technical measures:

Described protective device is also to be shaped on centre bore on the alignment azimuth axis of slide block; be vertically installed with guide rod in the centre bore; the lower end of guide rod is equipped with detection head and return spring, and the guide rod upper end is equipped with conical collision block, is being horizontally installed with the roller reversal valve that contacts on collision block on the slide block.

Described laser aligning checkout gear is that the support that has the horizontally-guided hole is installed on the lower surface of sill, the cylinder that moves horizontally is installed on the support, and the front end of cylinder is equipped with the straight trans secondary laser sensor that detects the workpiece linearity and along the guide post that moves in the pilot hole.

Advantage and good effect that the present invention has are: owing to widened sill, the V-type distance between seats that supports plug is strengthened, can suppress the bigger plug of diameter, give full play to the compacting ability of this machine; Because the straight trans secondary laser sensor that detects the workpiece linearity is installed on the sill lower surface, can on the instrument of operating desk, show detecting numerical value, detect numerical value not only accurately but also quick, improved operating efficiency greatly; The guide rod of regulating the roller reversal valve is installed on slide block in addition, makes master cylinder not have to keep the low pressure low cruise under the situation of workpiece, avoided pressing on the master cylinder excess of stroke situation to take place; Four guide pillars with slide block are kept to two at diagonal angle in addition, and the processing and manufacturing of this machine is more prone to, and have reduced manufacturing cost, and the present invention also has automaticity height, easy to operate advantage.
