Abstract
Disclosed is a spring type pull rod adjustor for the lever type simultaneous closing device of a multiplaten press. The spring type pull rod adjustor is mainly composed of two springs which are connected with each other in series, wherein, one spring has prepressing deformation, and the other spring is compressed to maximum deformation when used to install a pull rod. The adjustor makes a press have excellent simultaneous closing performance, makes the pull rod which needs regulating shortly in compressing still can bear the weight of pressing plates, and balances the surface pressure force of the upper and the lower pressing plates. The utility model has compact structure and reliable working performance, and is arranged above a rocker with convenient installation and adjustment.
Description
The utility model relates to the spring pull bar adjuster of multidaylight press lever simultaneous opening and closing device.
The lever simultaneous opening and closing device of multidaylight press is each pull bar of upwards swing drive by fork in press while closing course, and each laminate that will link to each other with each pull bar is mentioned and made each laminate energy while closed.The suffered pulling force of each pull bar changes within the specific limits in the closing course at the same time, but the active length of pull bar should remain unchanged.In the pressing process after press closes, because the error of slab size etc., distance between each pressing plate is not waited, and this unequal-interval is at random, in order to prevent to cause pull bar to destroy because of each pull bar active length is constant in the pressing process, the active length of having used the pull bar adjuster to come automatic adjusting yoke.Spring pull bar adjuster than hydraulic regulator etc. have simple in structure, cost is low, easy to maintenance, advantage such as polluted product not.But existing spring pull bar adjuster all has different shortcoming and defect, and this has influenced applying of spring pull bar adjuster.
Existing spring pull bar adjuster all only has a working spring.At the same time in the closing course, the active length of pull bar changes with the variation of the suffered pulling force of pull bar working spring, closure when therefore can not guarantee pressing plate without the spring adjuster of precompressed.And working spring is designed to two sections through the pull bar of the spring adjuster of precompressed, and with can only tension can not pressurized the sky cover connect; The elongation of pull bar is regulated by making pre-compressed spring produce bigger compression and is reached, and shortens to regulate then and is finished by one section pull bar moving in the sky cover.Closure when though this adjuster can guarantee pressing plate and since empty cover be installed in fork below, make the installation of adjuster, debugging all inconvenient; In addition, the weight that pull bar does not bear pressing plate when shorten regulating makes to have the pressure uneven phenomenon between the upper and lower plates, and this makes the density, thickness etc. of levels goods inconsistent.
The purpose of this utility model is to design closing motion when can guarantee pressing plate, can make again and in pressing process, must make to shorten the weight that the pull bar of regulating still can be born pressing plate, Installation and Debugging simultaneously are spring pull bar adjuster very easily all, to overcome the shortcoming and defect of existing spring pull bar adjuster.
Below given technical scheme reached above-mentioned purpose.
The utility model has three accompanying drawings.
Fig. 1 is a principle sketch of the present utility model.
Spring (5) is through precompressed, and the size of its pre-compressive strain is determined by positioner (16) and adjusted.Positioner (16) does not hinder spring (5) and produces the compressive strain bigger than its pre-compressive strain.Spring (10) is connected with spring (5).Positioner (17) is used for determining and adjusting the maximum compressive strain amount of spring (10), and this device does not hinder spring (10) and produces the compression littler than its maximum compressive strain.Adjuster connects with nut (8) with pull bar (1), the length of nut (8) compensation linkage (1).During debugging, should make the precompressed deflection of spring (5) be a bit larger tham pull bar (1) the compressive strain amount that suffered maximum pull produces spring (5) in the closing course at the same time, the maximum compressive strain amount of spring (10) then should be slightly smaller than pull bar (1) the compressive strain amount that suffered lowest pull produces spring (10) in the closing course at the same time.Like this, press is at the same time in the closing course, because between the pressure and the precompression of spring (5) of the size of the tensile force f of pull bar (1) when the maximum compressive strain of spring (10), thereby make spring (5) be in the precompressed deformation state always, spring (10) then remains on maximum compressive strain state, therefore the active length of pull bar (1) can not change closure when this has just guaranteed press.In pressing process, if the size of the tensile force f of pull bar (1) is greater than the precompression of spring (5), then spring (5) will further be compressed, and this makes active length of pull bar (1) regulate from the action elongation; And when pressure during less than the maximum compressive strain of spring (10) of the size of the tensile force f of pull bar (1), spring (10) will be upspring, make the active length of pull bar (1) shorten adjusting from action, at this moment the pulling force in the pull bar (1) equals the pressure of spring (10), so pull bar (1) is shortening the weight that still can bear pressing plate when regulating, this just makes the pressure between lower platen consistent.In addition, the utility model can be installed in the top of fork (14), and because the position of nut (8) can be arranged in the top, therefore makes the installation of whole simultaneous opening and closing device and debugging all very convenient.Obviously, adjuster also can be installed in the below of fork, also can to allow spring (5) that prestretching distortion or spring (10) are arranged be that the maximum tension limit deformation is arranged and do to change slightly, and spring (5) and (or) all available several spring serial or parallel connections of spring (10) form.
Fig. 2 is an embodiment of the present utility model.
The outer step of the interior step of the end of outer sleeve (7) and inner sleeve (6) end makes inner and outer sleeves form a two-section cover positioner that can only shorten to extend.Be loaded on spring (5) that this two-section puts and be pre-stressed to desired height by the outer step of the other end of the precompressed adjusting nut (4) of the other end of inner sleeve (6) and outer sleeve (7); protective nut (3) is twisted in the end of thread of inner sleeve (6); with the protection end thread, and prevent that with screw (12) it from becoming flexible.The outer face of protective nut (3) is a sphere, has cross recess on it, and an end skewer of alignment pin (13) is gone in the groove.The other end of alignment pin (13) is fixed on the flange face of flange shaft (2), in order to stop the rotation of protective nut (3) and inner sleeve (5), is convenient to the adjustment of precompressed adjusting nut (4).Place packing ring (11) on the interior step at outer sleeve (7) middle part, go up at packing ring (11) and place spring (10), gland (9) is pressed on the other end of spring (10).The thickness of changing packing ring (11) can change the maximum compressive strain amount of spring (10).
Accompanying drawing 3 is position and use situations that the foregoing description is installed on the lever simultaneous opening and closing device.
The flange shaft of adjuster (2) is contained on the fork (14), and an end of pull bar (1) is connected with pressing plate (15), and the other end penetrates adjuster and connects with nut (8), and the active length L that turns nut (8) and be compensation linkage (1) is to Len req.Because two adjusting nuts (4) and (8) all are positioned at the top of fork (14), add screw (12) and the alignment pin stop measures such as (13) adopted, make that the installation and the debugging of adjuster are all very convenient, the present embodiment compact conformation, reliable operation, both have the advantage of fluid pressure type pull bar adjuster and existing spring pull bar adjuster concurrently, overcome their shortcoming and defect again.
