Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
The utility model is a kind of snubber assembly when coming out of the stove for thermal treatment furnace side discharging door system duct, especially a kind of for large gauge drill pipe body through quenching furnance heating rear side discharging time avoid body to occur scratching or the snubber assembly of pit.
Its concrete structure as shown in Figure 1, at least comprises the snubber of two groups of parallel uses, and described snubber comprises stationary bearing 7 and slew buffer frame, and the top of described slew buffer frame and stationary bearing 7 is rotatedly connected; Slew buffer frame is star structure, comprise damping stock 1, buffer bar 3 and weight linear meter 5, one end of described damping stock 1, buffer bar 3 and weight linear meter 5 is all welded on the rotary sleeve 9 that is rotatedly connected with stationary bearing 7, weight linear meter 5 straight down, damping stock 1 and buffer bar 3 are divided into the both sides of weight linear meter 5, and the angle between described weight linear meter 5 and damping stock 1 and between weight linear meter 5 and buffer bar 3 and between damping stock 1 and buffer bar 3 is obtuse angle.
Wherein, between described damping stock 1 and weight linear meter 5, be equipped with stirrup 4 between buffer bar 3 and weight linear meter 5, stirrup 4 plays the effect of reinforcing.
Because buffer bar 3 is changed cumbersome, for avoiding causing wearing and tearing to body 12, be also beneficial to replacing, on described buffer bar 3, cover has copper sheathing 2 simultaneously.
The lower end of described weight linear meter 5 is provided with balancing weight 6, ensures that weight linear meter 5 is in position straight down when free state.
Described stationary bearing 7 is triangular supports, can improve stability, and the top of triangular supports is fixed with the connection bearing pin 8 perpendicular with triangular supports, rotary sleeve 9 be connected bearing pin 8 and be rotatedly connected.
The technical solution of the utility model utilizes lever balance theory, installs two groups of snubbers between side discharging door 13 and rollgang 11 additional.When side discharging door 13 is without unlatching, snubber remains static, and utilizes the equilibrium principle of lever, and the damping stock 1 contacted with fire door and splicing buffer bar 3 are in the top of weight linear meter 5, and are distributed on the both sides of weight linear meter 5 medullary ray.Snubber when installing needs rotating shaft center to pass a bridge 10 a little less than the body between discharging door and rollgang 11, produces and wound when avoiding the red heat body 12 after heating to come out of the stove.Two groups of snubber installation sites require parallel laying, ensure the synchronism that snubber adapter buffering and body 12 fall.The fixed position of snubber will be positioned at fire door and rollgang 11 lower middle side, close to rollgang, reduce the distance between snubber and delivery track as far as possible, like this when fire door is closed, body 12 slow releasing that snubber will previously have been received, alleviate surging force during whereabouts, thus avoid producing between the red heat body 12 after heating and rollgang 11 colliding with or scratching.Also therefore, the length of damping stock 1 is greater than the length of buffer bar 3, just connect with side discharging door 13 when being depressed by body 12 with damping stock 1, and buffer bar 3 just connects with rollgang 11 when being depressed by body 12 and is advisable, in order to avoid oversize time and side discharging door 13 and rollgang 11 overlaps or between gap too large and body falls, be all that body 12 can smoothly smooth-goingly to be passed through.
Meet the prerequisite of service requirements at snubber under, we have carried out module optimization to the structure of snubber and material thereof, at the copper sheathing 2 of splicing by buffer bar 3 outside edge brass material, make when contacting with body 12, scuffing can not be caused to body 12, and be beneficial to quick-replaceable after copper sheathing 2 produces modification.The damping stock 1 contacted with side discharging door 13 is owing to being in stove gate, be subject to high bake and frequently collide with side discharging door 13, use through long-time, easily bend, damping stock 1 is chosen for the stainless steel seamless pipe of φ 27 × 6 by us for this reason, and utilize the stability of triangular form, welding stirrup 4.The conveniently quick-replaceable of snubber entirety, utilizes and connects bearing pin 8 and be connected with stationary bearing 7 by slew buffer frame, and ensure slew buffer frame to connect on bearing pin 8 can in vertical plane 360 degree freely rotate.
The utility model and thermal treatment furnace side discharging door 13 and body pass a bridge 10, and cooperation discharging process between rollgang 11 is as follows: the above-mentioned 2 groups of snubbers assembled are fixed between thermal treatment furnace side discharging door 13 and rollgang 11, ensure that these 2 groups of snubbers are on same reference line, and rotary sleeve 9 passes a bridge 10 lower than body.When heat-treating operation at stove, body 12 drops down onto in thermal treatment furnace side discharging door 13, prepares discharging (as Fig. 2, tubulose states such as snubbers); Side discharging door 13 is driven by cylinder and slowly opens, be opened to certain angle, thermal treatment furnace side discharging door 13 contacts with the damping stock 1 of snubber, snubber rotates by connecting bearing pin 8 under the effect of external force, when side discharging door 13 is opened completely, the buffer bar 3 of snubber is rotated into the band material state of 10 one-tenth certain slanted angles of passing a bridge with body, body 12 rolls out simultaneously in side discharging door 13, with buffer bar 3 joint of snubber, thus reduce the surging force (as Fig. 3 snubber adapter state) when body is come out of the stove; When thermal treatment furnace side discharging door 13 slowly closing, while the slow lifting of the damping stock 1 contacted with side discharging door 13, the buffer bar 3 of snubber also slow circumvolve discharges the body after coming out of the stove (shown in Figure 4) downwards, until tumbled on rollgang 11 by gap bridge 10, carry out next process.
Employing the utility model can effectively reduce the surging force that body is come out of the stove, avoid body directly to drop on roller-way causes colliding with, scratch and the defect such as pit, that causes due to the defect of outer surface of tube body in reduction production process scraps phenomenon, the quality of effective raising finished product body, reduces the production cost of company.
