Description

Bilateral scissors upper tool post speedy erection system

Technical field

The present invention relates to bilateral scissors, particularly relate to the knife rest assembly method of bilateral scissors.

Background technology

When current smelter Wide and Thick Slab bilateral scissors upper tool post assembles, conventional method adopts removes bilateral scissors panel and upper tool post connecting rod two ends gland, then 2 10T screw jack (also needing 1 for subsequent use to adjust position at any time) are set up at two connecting rod places, above in knife rest and 2 draw rod positions set up the hydraulic jack (also needing 1 use adjusting and change top for subsequent use) of 1 50T respectively, then jacking disengaging is carried out to upper tool post simultaneously.And when installing, by the bilateral scissors of opposite side as support, upper tool post carries out heading into recovery by erection hydraulic top.Mainly there is four problems: 1, working space is narrow and small, the erection of the jack of rest position is very difficult, and only enough a people leans to one side frame top; 2, in knife rest detach procedure, because the stroke of top is limited, needs to set up cushion block frequently, construct very inconvenient; 3, construction needs institute's jack quantity more, and required manpower is also more; When 4, installing, because by the bilateral scissors of opposite side as support, easily cause damage to equipment.

Summary of the invention

The present invention is intended to address the aforementioned drawbacks, and provides a kind of bilateral scissors upper tool post speedy erection system.The present invention shortens construction period, and save manpower, guarantee construction quality, security also improves greatly.

For solving the problem, a kind of bilateral scissors upper tool post of the present invention speedy erection system, it comprises:

Step one, exit cutting edge;

Step 2, tripartite confirm, have a power failure, stop pressure, list;

Step 3, dismounting bilateral scissors panel connecting bolt and relevant oil pipe thereof;

Step 4, dismounting balancing cylinder and base, note carrying out dust prevention to each oil pipe;

Step 5, hang panel, utilize the big nut of F shape to revolve to get bar and remove upper tool post big nut;

Step 6, dismounting connecting rod both sides gland, note carrying out mark, to return dress;

Step 7, with bearing rib, two connecting rods are positioned welding, to go back to the correct location that dress imports;

Step 8, to hold with two 3T cucurbits and hang connecting rod, driving hangs 2 5T cucurbits, connect knife rest and bear its weight, the good connecting rod working plate of frame, be screwed into bolt, load onto top at knife rest lead to the hole site and get device, directly over carriage saddle, set up a 50T hydraulic jack, start simultaneously operating, knife rest and connecting rod are spun off in the lump and hang; It is that a upper side edge band is fluted that device is got on described top, and center is provided with the screw being screwed into nut;

Step 9, upper tool post to be overhauled;

The dress that returns of step 10, upper tool post recovers, when connecting rod and the correct contraposition of carriage saddle and after importing 10mm, at the added good special tooling plate of connecting rod, carriage saddle pull bar is screwed into the sleeve lead screw device of one end with screwed hole of centre plate, then utilize screw mandrel by its synchronous evenly press-in, note keeping measuring in the work progress moment, prevent uneven stuck of process; Described sleeve lead screw device is the sleeve pipe of one end cover closure, and cover plate central has screwed hole;

Step 11, time load bar side pressure lid, oil pipe, panel and big nut, time dress of end cap must coat flat sealant, and each oil connection must be cleaned out and check whether sealing is intact, adopts the tight method in diagonal angle to carry out during tight screw;

Step 12, restore balance oil cylinder fasten panels bolt, returns dress cutting edge;

Step 13, tripartite confirm, delisted, power transmission, send pressure, test run.

General thought of the present invention is design connecting rod special tooling plate, the screw on connecting rod and main eccentric shaft is utilized to pull, replace the use of screw jack, make top at knife rest lead to the hole site and get device, to replace 2 hydraulic jack near draw rod positions, during the dismounting of upper tool post, only need to utilize long jackscrew to carry out pushing up just can completing from operation simultaneously; And when returning dress, then design and produce a sleeve jackscrew, utilize the tension screw mandrel screw of knife rest to load onto sleeve screw mandrel and carry out frock operation.The dismounting operation of traditional handicraft only upper tool post at least needs 32 hours, and adopts the method only to need to complete for 16 hours; Traditional handicraft needs frequent adjustment jacking stroke, and set up cushion block, the labour intensity of workmen is larger; In the assembling process of traditional handicraft upper tool post, easily cause that to pull top dress speed irregular and produce inclination screens and to do over again event, and after adopting the method, the process of pulling can control more intuitively.Construction period shortens greatly compared with conventional method, and save a large amount of manpowers, ensure that construction quality, security also improves greatly.
