Hydraulic guide-plate type heavy cutting-off machine
Technical field
The present invention relates to shearing machine, particularly a kind of hydraulic guide-plate type heavy cutting-off machine.
Background technology
Between the main operating cylinder of knife rest and outputting power, all there are attaching parts such as bearing pin or sphere in traditional all kinds of shearing machines.Attaching parts are under the situation of long-time continuous heavy service, and serious wear causes the damage of various key positions easily.Not only man-hours requirement is longer for maintenance or replacing attaching parts, and the expense costliness, can't adapt to the needs of long-term production.
Summary of the invention
The present invention is intended to solve the problems referred to above that prior art exists, and a kind of hydraulic guide-plate type heavy cutting-off machine that can reduce complete machine parts and idle power consumption to greatest extent is provided.
The technical scheme that the present invention solves its technical problem employing is: a kind of hydraulic guide-plate type heavy cutting-off machine, comprise base, be installed in the frame on the base and be arranged on upper and lower knife rest on the frame, described frame is the setting of " well " word shape, and this frame inboard is provided with corresponding positioning guide rail and the adjustable gib of arranging; Upper tool post is inserted between two guide rails, and middle part has plug-in opening on it, is connected with cutter on the upper tool post of this plug-in opening top edge; Its upper end of described lower slide is connected with bottom knife, and its bottom is connected with main operating cylinder, and this lower slide and main operating cylinder are plugged in the plug-in opening on the upper tool post in the lump, and lower slide and frame are affixed; On the frame of both sides, described upper tool post below the return oil cylinder is housed; The push rod and the upper tool post of described main operating cylinder and return oil cylinder touch; Described upper rack lifts an eccentric swage.
Compared with prior art, the present invention is simple in structure, owing to do not have any attaching parts between upper tool post and the oil cylinder, the operation of employing ralocatable mode, the various faults that cause by parts wear have been avoided, substantially realized that mechanical system is non-maintaining, the present invention has reduced complete machine parts and idle power consumption to greatest extent, has thoroughly realized the update of traditional shearing technique.

Fig. 2 is that the A-A of Fig. 1 is to cutaway view.
Fig. 3 is the vertical view of Fig. 1.
Among the figure: frame 1, upper tool post 2, cutter 3, bottom knife 4, lower slide 5, main operating cylinder 6, return oil cylinder 7, base 8, plug-in opening 9, eccentric swage 10, positioning guide rail 11, adjustable gib 12, adjustable bolt 13.
The specific embodiment
The invention will be further described below in conjunction with drawings and Examples.
Referring to accompanying drawing 1-3, in the present embodiment, this hydraulic guide-plate type heavy cutting-off machine, comprise base 8, be installed in the frame 1 on the base 8 and be arranged on last lower slide 2 on the frame 1,5 and oil cylinder, frame 1 is the setting of " well " word shape, about it is plugged on by the two blocks of mortise wallboards in front and back on the side plate of two opening square holes, and be welded into as a whole, this frame 1 inboard is provided with corresponding positioning guide rail 11 and the adjustable gib of arranging 12, the two only is the material of hardening, and constitutes swallow-tail form plug-in mounting track between positioning guide rail 11 and the adjustable gib 12, is convenient to pumping of upper tool post 2.Upper tool post 2 is the guide-plate type structure, and it is inserted in the plug-in mounting track between two guide rails, and the middle part of upper tool post 2 is provided with plug-in opening 9, the upper tool post 2 of these plug-in opening 9 top edges be connected with cutter 3 with bolt in the cutter groove.With the affixed bottom knife 4 of bolt, its bottom is connected with main operating cylinder 6 in the cutter groove of lower slide 5 its upper ends, and this lower slide 5 is plugged in the plug-in opening 9 in the lump with main operating cylinder 6, and the rear and front end of lower slide 5 is fixed together by high-strength bolt and frame 1.On the frame 1 of the both sides, below of upper tool post 2 return oil cylinder 7 is housed all.The top of frame 1 lifts an eccentric swage 10, and the lower surface of this eccentric swage 10 is as for the top of lower slide 5 upper surfaces.The middle part of frame 1 be provided with plug-in opening 9 to the hole that cooperates.
Lower slide 5 is a wedge structure, be convenient to be inserted in the plug-in opening 9, and the unnecessary frame plate that goes out in these lower slide 5 rear and front ends is fixedlyed connected with frame 1 with high-strength bolt.Lower slide 5 tops are trapezium structure, and bottom knife 4 is fixed on the inboard of this trapezium structure.
The push rod and the upper tool post 2 of main operating cylinder 6 and two return oil cylinders 7 touch, and promptly move for floating between oil cylinder and the upper tool post, do not have any mechanical connection.
Adjustable gib 12 is fixed on by adjustable bolt 13 on the leading flank of frame 1, by adjusting adjustable bolt 13, can realize the gap between upper tool post 2 and the positioning guide rail 11, is convenient to adjust according to the specification of the workpiece of being processed, and is widely applicable.
Main operating cylinder 6 is fixed in the bottom of lower slide 5, the active force and the reaction force of vertical shear and lower slide 5 are cancelled out each other, frame 1 is not born vertical shear, fundamentally eliminated the frame of traditional type, because the effect of long-term shearing force causes stand stretch. tear. damage to complete machine and scrap.
The course of work of the present invention is: after workpiece was put well, when main operating cylinder rodless cavity was oil-filled, push rod was that piston rod promotes upper tool post 2 downwards and moves downward along the plug-in mounting guide rail, and lower slide 5 maintains static, thereby realizes shearing; After shearing is finished, there is the push rod of the return oil cylinder 7 of the frame of being installed in bottom that upper tool post 2 is upwards promoted to reset.
