The connecting structure for the continuous flat press to operate continuously and smoothly includes pressing hydraulic cylinder, piston rod, L-shaped board, trapezoidal heat insulating board, baffle, heat insulating pad, etc. and has less heat transfer and loss and effective protection on the inside structure. The present invention has the positive effects of simple reliable structure, obvious heat insulation, and capacity of ensuring the continuous smooth running of the continuous flat press.
Description
Technical field
The present invention relates to the technology of concora crush continuous press heating platen in a kind of Wood-based Panel Production equipment, particularly relate to the connection technique that overlength heating platen in the continuous press and pressurization promote hydraulic cylinder.
Technical background
The present invention is mainly used in the flat-crushing type continuous press that China designs and develops first, and continuous press heating platen length is longer, and heating back elongation is bigger.Coupling method and device that general pressurization promotes hydraulic cylinder and heating platen adopt two ends to be the method for stiff end: or fix at piston rod one end employing flange and its parts; Or the fixing other end self-aligning spherical support (promptly hinged) of an end, such connecting mode can conduct the heat of heating platen to pressurization and promote hydraulic cylinder, or, heating platen produces the problem that connects interference that promotes hydraulic cylinder with pressurization because adding thermal stretching, occur on the overlength heating platen and more can give prominence to, thereby directly cause the not up to standard of artifical plate product's precision.
Summary of the invention
For overcoming above-mentioned the deficiencies in the prior art, must change the connecting mode that continuous press heating platen and pressurization promote hydraulic cylinder, make normally even running continuously of continuous press, and can produce the high-quality goods and become possibility.For this reason, design a kind of novel reliable pressurization lifting hydraulic cylinder coupling method and device and become purpose of the present invention.The technical scheme that continuous press heating platen of the present invention and pressurization promote hydraulic cylinder coupling method and device is to want under the prerequisite that guarantees continuous press goods precision, design a kind of device, make continuous press heating platen and pressurization promote hydraulic cylinder has a simple and reliable practicality in actual installation adjustment, running steadily device.Technical scheme of the present invention is specifically to implement by following technical measures: a kind of heating platen of wood-based plate continuous press and pressurization promote the coupling method of hydraulic cylinder, it is characterized in that adopting a left side, right two block length bar L shaped plates 3 embed in the double hook groove on piston rod 2 tops, and be fixed on the heating platen S by bolt 8, mat insulation 6 places between piston rod 2 tops and the heating platen S, the L shaped plate 3 and piston rod 2 connection places that join with heating platen S have trapezoidal mat insulation 4 to separate, so hydraulic cylinder 1 and piston rod 2 can not be subjected to the heat conduction of elevated temperature heat pressing plate S, the L shaped plate 3 that one is installed with heating platen S embeds in the double hook groove on piston rod top, so heating platen adds the connection generation interference problem that thermal stretching also can not promote hydraulic cylinder to pressurization, realize that step of the present invention is: the installation site of at first determining good hydraulic cylinder, after press cylinder cylinder body 1 is in place with piston rod 2, hydraulic cylinder 1 is in the middle of crane is located in L shaped plate 3, just the double hook groove on the piston rod 2 appropriate with a left side, right L shaped plate 3 matches, after piston rod 2 put in place, press cylinder cylinder body 1 was connected the location by hanging tight the D of mechanism with frame G.Because of heating platen S can produce up to 220 ℃ or above high temperature when working, but piston rod 2 tops have mat insulation 4 and heating platen S to separate, stop the heat conduction, be assigned to piston rod 2 and can transmit heat thus with the contacted L shaped plate 3 of heating platen S, damage the seal in the hydraulic cylinder, at this moment, leave dovetail groove between L shaped plate 3 and the double hook groove, after embedding trapezoidal mat insulation 4 in this dovetail groove, stoped the transmission of heat effectively and scattered and disappeared.A kind of device of realizing above-mentioned heating platen and pressurization lifting hydraulic cylinder coupling method; it is characterized in that it is by press cylinder cylinder body 1; piston rod 2; L shaped plate 3; trapezoidal mat insulation 4; baffle plate 5; mat insulation 6; screw 7; bolt 8 is formed; wherein: can bear the hydraulic cylinder rated pressure; the mat insulation 6 of heatproof more than 250 ℃ is located in earlier on the heating platen S below the piston rod 2; a left side; right two cross sections are symmetrically placed in mat insulation 6 both sides for the rectangular iron block L shaped plate 3 of being inverted L shaped shape; its upper end embeds the left side of piston rod 2 respectively; in the right groove; link to each other with heating platen S by 8 hexagon socket head cap screws 8; L shaped plate 3 adopts 45 steel; because of it directly contacts with heating platen; and when hydraulic cylinder promotes; L shaped plate 3 need be born certain shock loading; adopt modifier treatment HB220-250; make it improve toughness and intensity; connected hexagon socket head cap screw 8 materials are carbon steel; mechanical performance grade 10.9; the trapezoidal mat insulation 4 that has identical character and requirement with mat insulation 6 is installed in a left side of being convenient to mount and dismount; the inboard of right L shaped plate 3; each is separately fixed at the rear and front end of piston rod 2 of the front and back of mat insulation 6 baffle plate 5 with two screws 7; piston rod 2 adopts the 45# forged steel; and whole modifier treatment HB220-250; make it have good comprehensive mechanical performance; can bear heavy load and impact; head is processed into the double hook flute profile; a good installation environment is provided for trapezoidal mat insulation 4; increase its contact-making surface; when operating temperature is too high, protected the internal structure of piston rod 2 effectively.Leave the gap of 1.5mm-5.5mm between trapezoidal mat insulation 4 and mat insulation 6 and the L shaped plate 3, not only guarantee its swell increment but also effectively utilize air and isolate, stop the transmission of its heat.The installation steps of draw bail of the present invention are: the installation site of at first determining good hydraulic cylinder, after press cylinder cylinder body 1 is in place with piston rod 2, hydraulic cylinder 1 is located in L shaped plate 3 through crane, appropriate the matching of double hook groove on the piston rod 2 at this moment with L shaped plate 3, after piston rod 2 put in place, press cylinder cylinder body 1 was connected the location by hanging tight the D of mechanism with frame G.Because of heating platen S can produce up to 220 ℃ or above high temperature when working, but piston rod 2 tops have mat insulation 4 and heating platen S to separate, stop the heat conduction, be assigned to piston rod 2 and can transmit heat thus with the contacted L shaped plate 3 of heating platen S, damage the seal in the hydraulic cylinder, at this moment, leave dovetail groove between L shaped plate 3 and the double hook groove, after embedding trapezoidal mat insulation 4 in this dovetail groove, stoped the transmission of heat effectively and scattered and disappeared.Baffle plate 5 is connected with piston rod 2 usefulness screws 7, plays the effect of blocking trapezoidal mat insulation 4.
Good effect of the present invention is that this is simple and reliable for structure, easy for installation, effect of heat insulation is obvious, add at heating platen and still make pressurization promote hydraulic cylinder under the situation of thermal stretching to be connected with heating platen reliably, lifting puts in place, avoided unnecessary hinged structure, thereby guaranteed that pressurization promotes hydraulic cylinder and heating platen operate as normal, continuous press can be become a reality in normally continuous even running.
