Description
The reference of cross reference correlation
This application claims submit on 01 29th, 2019 application No. is a kind of 2019100851942, entitled " non-oxidations
The priority of the Chinese patent application of the drop stamping production line of heating ", above-mentioned application reference are incorporated herein.
Technical field
The present invention relates to drop stamping technical field, a kind of particularly drop stamping production line of scale-free heating.
Background technique
Currently, high-strength steel material mainly has the naked steel plate of 22MnB5 (surface does not have coated steel in automobile drop stamping industry
Plate) and its clad plate (surface have plating/coating steel plate) both.Although clad plate can produce to avoid its surface when heated
Raw oxide skin, still, due to its valence height, and when being heated to certain temperature, coating easily melts, and coating is caused to stick in
On furnace roller, material frame and mold, equipment life is influenced, therefore, comparatively, the lower naked steel plate of price is using very extensive.
Existing drop stamping production line mostly uses the long line heating furnace of roller-bottom type to heat steel plate, and still, this will lead to
In air, after naked steel plate heats in air, surface can generate oxide skin for exposure when steel plate heats.Oxide skin is mainly by oxygen
Change ferrous iron, ferroso-ferric oxide, di-iron trioxide composition, matter is crisp, without extensibility, acts under mechanical action with hot-working
Under, it is easy to it generates cracking and falls off.Since the hardness of oxide skin is higher than mold, naked steel plate on mold when forming, thereon
Oxide skin will increase the friction between steel plate and mold, increase the abrasion of mold, reduce the service life of mold, simultaneous oxidation skin
Generation can reduce the processability of naked steel plate, pull product generation, furthermore, the thermal conductivity of oxide skin is very low, seriously affects
Heat transfer between naked steel plate and mold.
To solve the above problems, currently, thermoforming production line on the market uses the naked steel plate oxygen of box type heater inhibition
The production method of change, this method are that inert gas is passed through in box type heater to reduce oxygen content.Existing box type heater
Burner hearth protrude into height space needed for burner hearth picks and places tablet as needing to reserve tablet fetching device, and held inside burner hearth by gas
Amount and the biggish heat-preservation cotton of thermal capacity are constituted, and therefore, existing box type heater furnace height is larger, space is very big, causes lazy
It is very long that property atmosphere establishes the period；And online opening and closing fire door is needed, the oxygen content drop in burner hearth is low less than unlimited, and low-oxygen environment is only
The oxidation rate of naked steel plate at high temperature can be slowed down, the generation of oxide skin can not be prevented, especially when furnace gas mixing is uneven
When, naked steel plate oxidation can aggravate, and can not accomplish scale-free heating.
On the basis of existing box type heater (mode for protruding into burner hearth pick-and-place tablet), to meet productive temp demand,
The layout type for needing three six layers of heating furnace in one line or two eight layers of heating furnace opposites to place in opposite directions, when six layers of arrangement
Or when eight layers of heating furnace, heating furnace short transverse is excessively high, and feeding, reclaimer system are unable to complete feeding and feeding action；And it is such
Arrangement will lead to that the distance between heating furnace and press are excessive, it is heated after high temperature tablet come out of the stove after be sent to press institute
The overlong time needed, tablet temperature sharp fall in this course, influences subsequent forming temperature.
Patent (CN108202226A) discloses a kind of almag plate warm forming production line and its production technology, if
It sets corresponding charging, the basic production line arrangement that feeding, heat treatment, press are handled, and discloses a kind of multiple hearth and add
Hot stove furnace body rotation technique, i.e. " closing that multilayer Split rotary heating furnace is made of multiple furnace bodies, circular row cloth knot
Structure, the number of the furnace body are 3-10, wherein each furnace body can carry out 360 degree of circulation fortune along the sliding rail around rotation center
It is dynamic ", it is arranged by above-mentioned rotatable multicell heater, Lai Tigao production efficiency.But the production line is for magnesium-aluminum alloy plate
Warm working technique and be arranged, heating temperature be 450-600 DEG C, soaking time 20-60 minute, and automobile high-strength steel add
Hot temperature is at 900-930 DEG C, and the heating of part and soaking time were no more than 10 minutes, and otherwise part can be scrapped, therefore the life
Producing line and its production technology are not used to the production of the high-strength steel part of automobile, less can solve problem of oxidation when bare board heating；
In addition, each heating furnace, which does annular 360 degree of circulation rotatings of translation, can be such that cable, pipeline etc. winds mutually, is tired easily broken.
In view of the short slab of current technology, it is badly in need of developing a kind of drop stamping production line of scale-free heating, this production line can
Meet the needs of the high beat scale-free heating of naked steel plate, while the aerial range ability of hot blank and temperature drop can be reduced, mentions
The quality and added value of high product.

The blank after blank positioning system 70 positions is stated to be put into the press 80.
Preferably, the press 80, the truss, the loading bay 40 and the conveyer 100 long axis direction
Central axes are overlapped, and the first scale-free heating system 60 and the second scale-free heating system 61 are located at the truss
Long axis direction two sides, be conducive to shorten producing line length.The turntable 602 reciprocally rotates 180 °, so that described
The fire door 6013 of one scale-free heating system 60 and two multiple hearth scale-free heating furnaces 601 in the second heating system 61 can be handed over
For towards truss to carry out out pan feeding.When any multiple hearth scale-free heating furnace 601 towards truss to carry out out pan feeding when, furnace
Door 6013 is parallel with truss.
Specifically, the truss includes the first column piece 501, the second column piece 504 and divides in conjunction with shown in Fig. 2 and Fig. 3
The first crossbeam 505 and second cross beam 506 of the first column piece 501 and the second column piece 504 Yong Yu not connected.It is described
First feeding device is set on the first crossbeam 505, and second feeding device is set on the second cross beam 506.
The first column piece 501 and the second column piece 504 are respectively equipped with for first feeding device and second feeding
The window that device passes through, first feeding device pass through the window and carry out to the multiple hearth scale-free heating furnace 601
Material, second feeding device pass through the window and take the blank for completing heating in the multiple hearth scale-free heating furnace 601
It walks, and blank is put into press 80.Further, first feeding device and second feeding device respectively include setting
The elevating lever 503 that is placed on the first crossbeam 505 and/or the second cross beam 506 and it is connected to the outstanding of the elevating lever 503
