Abstract

The utility model discloses a universal puncher. The universal puncher has the functions of the linear shearing and the rotary shearing of boards and the punching shearing of section steels, which realizes that one machine has a plurality of functions. The utility model has the advantages of simple structure, small size, light weight, and large energy. The thicknesses of the boards which are sheared are not greater than 4 mm. When punching shearing, the diameters of round steels are not greater than 28 mm, the sides of square steels are below 22 mm, and the sides of angle steels are below 50 mm. The body of the universal puncher is designed into convex shape, so the universal puncher can shear the boards of random widths and lengths. The universal puncher can be suitable for middle and small business and the worksites of constructions. One universal puncher can replace a sheet shearer, vibrating shears, and a punching machine.

Description

Universal puncher

The utility model is the improvement of punching lathe, and it has, and sheet linear is sheared, oscillating curve is sheared and three kinds of major functions of section bar punching.

Sheet shearing and various section bar punching are that all kinds of enterprises use one of maximum method for metal working.But present most unit all is to use plate shearing machine, oscillating curve to cut and three kinds of equipment of punch press, finishes the machining of this respect.Though current have a combined punching and shearing lathe, can realize that the straight line of sheet material is sheared and the section bar punching, do not see three function lathes as yet with nibbling shear.Therefore, the utility model has been done improvement to complete machine structure, has increased new function to punching (shearing) machine.

The purpose of this utility model, it is many to provide a kind of function, simple in structure, in light weight, easy to operate, the multi-purpose punching and shearing machine bed that work efficiency is high, this lathe is specially adapted to medium-sized and small enterprises and use in the construction and installation building site, and it can realize that thickness is not more than the straight line and the rotary shearing of 6 millimeters sheet material, and diameter is less than 30 millimeters garden steel, 65 * 65 * 6 millimeters angle steel, the punching of 20 * 20 millimeters square steel, shear width and length are not limited by fuselage.

The utility model is realized by following proposal: motor 11 drives axle 17 by V-belt 13 and belt pulley 12 and 14, and flying wheel 16 and gear 24 are housed on this axle.Gear 24 and gear 23 engagements drive axle 18.Gear 19 on this and gear 20 engagements drive main crankshaft 10, and this drive master slider 7 is done and moved both vertically.The cutter 1 that straight line is cut is installed in master slider 7 bottoms, with the bottom knife 1 that is installed on the convex shape fuselage 15, realizes sheet shearing, and the middle part studs with: the geometric form cutter 5 of garden, angle, square steel and the geometric form cutter 5 that is set on the clamping plate 25, realize the punching of section bar.The motion of clutch 2 control master sliders 7.

Its fuselage 15 is convex, and there is a horizontal component 26 its underpart, as mounting seat, the vertical part 27 that links to each other with horizontal component 26 is not straight, and having 90 ° to turn round 28, this right side bottom line that turns round is not a level, but by behind the forward direction, have a down dip, its effect is gone ahead a sheet material left side that has cut off, walks under dextrad is oblique, thereby realizes shearing width and the unrestricted purpose of length, the through hole 29 of fuselage is that clamping plate 25, clamping plate space mounting master slider 7 are installed.

Gear 20 and gear 21 engagements are realized revving up, and drive nibbling shear bent axle 8.This bent axle drives nibbling shear slide block 6, does rectilinear motion.This slide block 6 is installed blade 4, realizes rotary shearing.Nibbling shear slide block 6 is cut clutch 9 controls by shaking.The shear blade 4 that shakes is fixing with trip bolt 3, can conveniently pull down and load onto.

This machine uses 3KW, 4 grades of motor, and it is 574 rev/mins that 45 rev/mins of main crankshaft rotating speeds, oscillating curve are cut speed of crankshaft, and complete machine weight is about 400Kg, and all gears all adopt cylindrical gear of straight tooth, m=4.Master slider and nibbling shear ram travel are respectively 30mm and 4mm, can adopt eccentric shaft or bent axle form.

The utility model is compared with existing puncher, has following advantage: (1) has the function that nibbling shear is realized the sheet material rotary shearing; (2) this machine is in light weight, low cost of manufacture, its weight be about same specification multi-purpose punching and shearing machine about 3/4; (3) this machine has designed the convex shape base and has made the width of straight line shear and the restriction that length is not subjected to fuselage; (4) this machine adopt tramp with one's feet solenoidoperated cluthes than manual control be more convenient for the operation.

Fig. 1 is the side structure schematic diagram of this machine.Fig. 2 is the Facad structure schematic diagram.

Fig. 3 is a kinematic scheme.Fig. 4 is the front view of fuselage 15.

Fig. 5 is the right view of fuselage 15.

Realizing scheme of the present utility model, is to manufacture in middle-size and small-size machinery plant, all enterprises with founding, forging and pressing, manufacturing and metal-cutting capacity, but all creation of this machine of complete independently. Do not possess the enterprise of founding and manufacturing capacity for those, can solve by horizontal combination. This machine does not have the part of high accuracy and special processing process.

Claims

1, the utility model is a kind of omnipotent punching lathe, it is characterized in that: do power with a motor, by a cover reducing gear, drive main crankshaft 10 and nibbling shear bent axle 8; Main crankshaft 10 drives master slider 7 Straight line shearses 1 and geometric type cutter 5; Nibbling shear bent axle 8 drives nibbling shear slide block 6 and blade 4.
