Description

A kind of structure of machine frame body of steel bar shearing machine

Technical field

What the present invention relates to is a kind of bar cutter, particularly be a kind of structure of machine frame body of steel bar shearing machine.

Background technology

At present, the bar cutting production line need dispose bar cutter.The Rack Body structure of the bar cutter of prior art is: the following tool rest that bottom knife is housed is fixed on the mainboard of Rack Body; The travel(l)ing rest lift and the upper cutter head of bar cutter conveying steel is the mechanism that belongs to different respectively, and when shear reinforcement, they are respectively by separately power drive; The subplate bottom is an enclosed construction.

There is following shortcoming in the Rack Body structure of above-mentioned prior art bar cutter:

1. bottom knife is contained in down on the tool rest, the blade exchange inconvenience;

2. will descend on the tool rest deposition dust and iron filings to bring sliding position into easily, cause the damage of body;

3. the travel(l)ing rest lift is the mechanism that belongs to different respectively with upper cutter head, mechanism's complexity, and the energy consumption height, the fault rate height influences shear efficiency and service life.

Summary of the invention

The objective of the invention is to overcome the deficiency of above-mentioned technology, provide a kind of employing that connection activity feeding lift on the upper cutter head of cutter is being housed, bottom knife directly is fixed on the mainboard of Rack Body, can realize less trouble, stable, reliable a kind of structure of machine frame body of steel bar shearing machine.

The technical scheme that solves the problems of the technologies described above is: a kind of structure of machine frame body of steel bar shearing machine, described structure of machine frame body of steel bar shearing machine comprises: the structure of machine frame body of steel bar shearing machine that carrier base and carrier base support, described structure of machine frame body of steel bar shearing machine comprises: the bar shaped side plate that is positioned at the left and right sides, the two sides of side plate are clamped by subplate and mainboard, and securing member is with the fastening one of subplate, side plate and mainboard; Be provided with the driver element of band driven plunger in the through hole on bar cutter Rack Body middle part subplate and mainboard, the driven plunger lower end connects upper cutter head; Upper cutter head is fixed with cutter; It below cutter the workbench that runs through the bar cutter Rack Body; Be fixed with the bottom knife that cooperates with cutter on the medial surface of the mainboard below workbench; Be fixed with the compressed oil cylinder of band clamping piston on the lateral surface of the mainboard above the workbench, pressure head is equipped with in the clamping piston end; Described symmetric position place in the upper cutter head side is hinged with an end of two activity feeding lifts, is hinged on the extension plate of the other end of two activity feeding lifts on two rollers, and two rollers are slidably supported on the guide rail of carrier base both sides.

The invention has the beneficial effects as follows: the present invention overcomes the defective of prior art, utilizes novel cutter Rack Body structure to substitute existing Rack Body structure, has removed time tool rest, and mainboard is not only as tool rest down but also as the agent structure of Rack Body.Be connected with activity feeding lift and substitute existing travel(l)ing rest lift on upper cutter head, when upper cutter head drive cutter was realized going up down cut, drive activity feeding lift moved up and down, and finished the cutter relieving action in the shear history.The through hole that form to connect in the subplate bottom promptly forms unenclosed construction, substitutes the subplate of prior art bottom enclosed construction, has simple in structurely, compact, is easy to processing, transportation, and easy to maintenance, reliable operation is saved energy consumption, the advantage that fault rate is low.

The specific embodiment

Below in conjunction with accompanying drawing embodiments of the invention are described in further detail.

Fig. 1 is a front view of the present invention; Fig. 2 is the A-A cutaway view among Fig. 1; Fig. 3 is the B-B cutaway view among Fig. 2; Fig. 4 is the C-C cutaway view among Fig. 2.

As shown in the figure, the invention provides a kind of structure of machine frame body of steel bar shearing machine, described structure of machine frame body of steel bar shearing machine comprises: the structure of machine frame body of steel bar shearing machine 20 that carrier base 12 and carrier base 12 support, described structure of machine frame body of steel bar shearing machine 20 comprises: the bar shaped side plate 10 that is positioned at the left and right sides, the two sides of side plate 10 are clamped by subplate 1 and mainboard 9, and securing member is with subplate 1, side plate 10 and mainboard 9 fastening one; Be provided with the driver element of band driven plunger 3 in the through hole on bar cutter Rack Body 20 middle part subplates 1 and mainboard 9, driven plunger 3 lower ends connect upper cutter head 4; Upper cutter head 4 is fixed with cutter 7; Below cutter 7 the workbench 8b that runs through bar cutter Rack Body 20; Be fixed with the bottom knife 6 that cooperates with cutter 7 on the medial surface of the mainboard 9 below workbench 8b; Be fixed with the compressed oil cylinder 8 of band clamping piston 13 on the lateral surface of the mainboard above the workbench 8b 9, pressure head 8a is equipped with in clamping piston 13 ends; Described symmetric position place in upper cutter head 4 sides is hinged with an end of two activity feeding lifts 5, be hinged on the extension plate of the other end of two activity feeding lifts 5 on two rollers 15, two rollers 15 are slidably supported on the guide rail 12a of carrier base 12 both sides.
