Abstract
The invention relates to a clearance adjusting mechanism for a hydraulic gate typed plate shearing machine, comprising an upper tool holder body and a lower tool holder body. The back of the upper tool holder body is provided with an upper roller and a lower roller, the front of the upper tool holder body is provided with a front roller with a spring, the front lower end of the upper tool holder body is fixedly provided with an upper blade and the upper end of the lower tool holder body is fixedly provided with a lower blade. The clearance adjusting mechanism is characterized in that the upper roller is fixed, the lower roller is connected with a fore-and-aft moving device and the center of the lower roller and the cutting edge of the lower blade are on the same horizontal plane. The upper roller of the invention is fixed, the lower roller is assembled on an eccentric shaft, and the center of the lower roller and the cutting edge of the lower blade are on the same horizontal plane, therefore, when shearing a plate, additional shearing moment is not generated, and the upper tool holder body does not rotate and the blade clearance keeps invariant when shearing, thus ensuring shearing quality.
Description
Technical field
The present invention relates to hydraulic gate type guillotine shear, relate in particular to the clearance adjustment mechanism of hydraulic gate type guillotine shear.
Background technology
In order to obtain plate shearing area quality preferably, during the plate shearing machine shear, guarantee the gap blade Δ and be satisfied formula Δ=0.08 δ, so when shearing the sheet material of different thicknesss of slab, the gap blade of plate shearing machine needs often to adjust by shear material thickness δ.
The clearance adjustment mechanism of hydraulic gate type guillotine shear is the most commonly used with three fulcrum types, and promptly tool-post structure rotates it by three roller adjustment, thereby adjusts the gap of cutter and bottom knife.Be provided with upper roller and bottom roller in the tool-post structure back, the tool-post structure front is provided with the front wheel of band spring, and the spring of front wheel can make tool-post structure be close on the upper and lower roller after the precompressed.Bottom roller is fixed, and upper roller is assembled on the eccentric shaft.During the adjusting play, drive eccentric shaft by rotating shaft and rotate, making tool-post structure is that rotate in the center of circle with the bottom roller, thereby adjusts the gap of upper and lower blade.Because gap blade is regulated by upper roller, is referred to as mode.But also there is drawback in this mode gap blade guiding mechanism of going up, because the center of bottom roller is higher than the bottom knife edge of a knife, is that fulcrum can produce shearing moment with the bottom roller when shearing, the moment of shearing, this moment rotates tool-post structure, and it is big that gap blade becomes, thereby influence shearing quality.
Summary of the invention
The last mode gap blade guiding mechanism that the present invention is directed to existing hydraulic gate type guillotine shear can't guarantee the problem of gap blade when shearing, having carried out research improves, a kind of down-regulation type gap blade guiding mechanism is provided, uses this guiding mechanism can guarantee gap blade.
In order to solve the problems of the technologies described above, the present invention adopts following technical scheme:
The clearance adjustment mechanism of hydraulic gate type guillotine shear, comprise upper slitter support body and lower slide body, the back of upper slitter support body is provided with upper roller and bottom roller, upper slitter support body front is provided with the front wheel of band spring, the preceding lower end of upper slitter support body is fixed with cutter, and the upper end of lower slide body is fixed with bottom knife, and described upper roller is fixed, described bottom roller with move forward and backward device and link to each other, the center of described bottom roller and the described bottom knife edge of a knife are on the same horizontal plane.
Further, the described device that moves forward and backward comprises connecting axle, upper connecting rod, last pin, middle connecting rod, following pin, lower connecting rod and the eccentric shaft that is linked in sequence, and described eccentric shaft is connected with described bottom roller.The adjustable length of connecting rod in described.
Effect of the present invention is: the upper roller among the present invention is fixed, bottom roller is assembled on the eccentric shaft, and the center of bottom roller and the bottom knife edge of a knife are on the same horizontal plane, when shearing sheet material, can not produce additional shearing moment, during shearing, the upper slitter support body can not rotate, gap blade remains unchanged, and can guarantee shearing quality.
Description of drawings
Fig. 1 is a structural representation of the present invention.
The specific embodiment
Below in conjunction with accompanying drawing the specific embodiment of the present invention is further described.
See Fig. 1, the present invention includes upper slitter support body 1 and lower slide body 14, the back of upper slitter support body 1 is provided with upper roller 2 and bottom roller 4, upper slitter support body 1 front is provided with the front wheel 3 of band spring, the preceding lower end of upper slitter support body 1 is fixed with cutter 12, and the upper end of lower slide body 14 is fixed with bottom knife 13, and upper roller 2 is fixed, bottom roller 4 with move forward and backward device and link to each other, the center of bottom roller 4 and bottom knife 13 edges of a knife are on the same horizontal plane.
The above-mentioned device that moves forward and backward comprises connecting axle 11, upper connecting rod 10, last pin 9, middle connecting rod 8, following pin 7, lower connecting rod 6 and the eccentric shaft 5 that is linked in sequence, and eccentric shaft 5 is connected with bottom roller 4.The adjustable length of middle connecting rod 8.
The course of work of the present invention is as follows:
When plate shearing machine need be adjusted gap blade, axle 11 is rotationally connected earlier, the method of rotating can be electronic, also can be manual, the rotation of connecting axle 11 drives upper connecting rod 10 and rotates around the axle center of connecting axle 11, the rotation of upper connecting rod 10 drives the middle connecting rod 8 of going up pin 9 and adjustable-length and moves up and down, pin 7 and lower connecting rod 6 rotated around eccentric shaft 5 under the motion of middle connecting rod 8 drove, the rotation of eccentric shaft 5 drives bottom roller 4 and moves forward and backward, because front wheel 3 band springs, can float, upper roller 2 is fixed, drive upper slitter support body 1 like this and swing, can adjust the position of upper tool post body 1 like this, thereby reach the purpose of adjusting gap between cutter 12 and the bottom knife 13 around upper roller 2.
