Abstract
The invention provides a diagonal rolling double-roller puncher having a cast-weld structure and relates to hot rolling seamless tube equipment. The puncher of the invention comprises a main frame, two roller devices arranged in the main frame, two guide boards arranged on the side wall of the main frame, a guide board locking unit and a guide board regulating unit, wherein the main frame is a closed frame casting and the guide board, the guide board locking unit and the guide board regulating unit are respectively welded pieces. The invention solves the problem that a full-casting puncher is heavy and the stress state of an all-welded puncher main frame is inferior. The closed frame is manufactured by using a uniformly stressing cast structure. The secondary force bodies are manufactured by using the advantages that the welding structure is light and beautiful. The frame has high rigidity and strength and the whole device is light and flexible to move.
Description
Technical field
The present invention relates to hot rolling seamless tube equipment, particularly a kind of diagonal rolling double-roller punch.
Background technology
Existing diagonal rolling double-roller punch also is connected with guide plate arrangement except that main stand, its structure can be divided into two kinds: a kind of is full cast type, and another kind is full welded type.Full cast type structure is all to be cast as all structures that can be fixedly connected with frame (comprising locking and the adjusting device of main stand, guide plate arrangement and guide plate etc.) as a whole; Not only cause equipment heaviness, non-main beaer--the redundant waste of material of guide plate arrangement; And because complex structure; Make casting manufacturability poor, influence equipment quality.Full welded structure is all to be welded into as a whole with the structure that frame is fixedly connected, though structure is light and handy, the external form neat appearance, it makes that main beaer--the stress state of main stand is bad.The cast type frame is because of steady quality, and the load of holding capacity is evenly distributed in the operation of rolling, can not produce stress and concentrate, so force-bearing situation is good; And the welded type frame can produce stress and concentrates in the commissure, so force-bearing situation is bad.How on the different parts of punch equipment, utilizing casting and welding procedure advantage separately, maximize favourable factors and minimize unfavourable ones, adopt casting, welding structure manufacturing diagonal rolling double-roller punch, is the technical issues that need to address of the present invention.
Summary of the invention
The object of the invention is intended to overcome the deficiency that prior art exists; A kind of diagonal rolling double-roller punch that adopts cast-weld construction is provided; Solve heavy, the complete bad problem of welded type punch main stand stress state of full cast type punch equipment; Adopted stressed uniform cast structure to make the closed frame open frame; Utilized the light and handy advantage attractive in appearance of Welding Structure to make non-main beaer again, not only made the good rigidly of main stressed frame, intensity high, and make that integral device is in light weight, motion flexibly.
The present invention realizes through following technical scheme:
A kind of diagonal rolling double-roller punch that adopts cast-weld construction; Comprise: main stand; Place two roll devices in the main stand, be arranged on two guide plate arrangements, guide plate locking device, the guide plate adjusting device of the main stand left and right sides, it is characterized in that: described main stand is a kind of closed framework body foundry goods; Said guide plate arrangement, guide plate locking device, guide plate adjusting device are respectively independently weldment, respectively with bolt and the key face in the left and right sides of main stand that is fixedly connected.
Said two guide plate arrangements are that the rotating guide frame is installed on two bases that adopt steel plate to make, and on the rotating guide frame guide plate are installed, and two bases are with bolt and the key face in the left and right sides of main stand that is fixedly connected.
Said two guide plate locking devices are parts that locking device is installed on two locking base plates that adopt steel plate to make, and two locking base plates are with bolt and the key face in the left and right sides of main stand that is fixedly connected.
Said two guide plate adjusting devices are parts of installation adjusting device on two adjustment base plates that adopt steel plate to make; Two adjustment base plates are with bolt and the key face in the left and right sides of main stand that is fixedly connected, and link with two universal-joint spindles and the interior screw jack of main stand.
Described two roll devices are installed in the main stand, are slidingly matched with main stand.
Described screwdown gear is installed in the top of main stand; Described pressuring upper device is installed in the bottom of main stand.
The present invention compared with prior art owing to adopted the cast main body frame, makes the frame integral rigidity strengthen, and the operation of rolling is very stable, and roll big bounce can not take place, and makes that producing large diameter steel pipe becomes possibility; Owing to adopted the welded type guide plate arrangement, alleviated weight of equipment, make guide plate shift out and rotate flexibly, thereby can make the guide plate accurate positioning, saved the time of changing guide plate; Owing to used welded type guide plate locking device and other welding assembly, make each parts of punch arrange in order, and enlarged the inner space, be convenient to maintenance and adjustment equipment; Each is partly stressed different with function and adopted corresponding structural material respectively because global design is according to punch, thereby whole structure is more rationalized.
Description of drawings
Fig. 1 is a structural representation of the present invention;
Fig. 2 is the left view of Fig. 1;
Fig. 3 is that guide plate arrangement is from connecting the sketch map that the end is seen;
Fig. 4 is the structural representation that the guide plate adjusting device shows the connection place;
The present invention is elaborated through preferred embodiment below in conjunction with accompanying drawing.
The specific embodiment:
Like Fig. 1,2,3, shown in 4; A kind of diagonal rolling double-roller punch that adopts cast-weld construction; Comprise: main stand 1; Place two roll devices 2 in the main stand, place two guide plate arrangements 3, guide plate locking device 4, the guide plate adjusting device 5 of main stand 1 left and right sides, and the screwdown gear 6 and pressuring upper device 7 of adjusting two roll device distances respectively.
Described main stand 1 is a foundry goods, and it has rejected irregular part, only stays a closed framework structure, has improved casting manufacturability; Because unnecessary material is not attached thereto around not having, so can be designed to eight pure beam four-post frame support bodys, is a comparatively ideal beaer, bears two roll 2-1 and 2-2 specially and transmit the draught pressure of coming.
Described two roll devices 2 are installed in the main stand 1, are slidingly matched with main stand.
Described two guide plate arrangements 3 are designed to two separate components, and two base 3-3 are weldments, and the parts of guide plate arrangement are installed on the base.Rotating guide frame 3-1 is arranged on the described guide plate arrangement 3, and rotating guide frame 3-1 can rotate, and is convenient for changing guide plate 3-2 mounted thereto.For the firm main stand that is incorporated into, the base 3-3 of said two guide plate arrangements 3 is separately fixed at main stand 1 left and right sides face with bolt 3-4 and key 3-5.
Described two guide plate locking devices 4 are designed to two separate components, and two locking base plate 4-1 are weldments, and the parts of locking device are installed on the base plate.Described guide plate locking device 4 is in order to firm rotating guide frame 3-1, to bear the draught pressure that is produced when punch is worked.For the firm main stand that is incorporated into, two locking base plate 4-1 of said two guide plate locking devices 4 are separately fixed at main stand 1 left and right sides face with bolt 4-2 and key 4-3.
