Abstract

The utility model relates to a table folding shearing machine, belonging to a manual folding shearing device for metal plates. The table folding shearing machine is provided with a machine base, and the machine base is provided with an eccentric pressing device and a folding arm with a bearing axle. One end of the axle of the folding arm is provided with a limiter, and the right back part of the machine base is provided with a pair shears. Therefore, miniature thin metal plates can be pressed, bent and sheared, and folding angles between 120 DEG and 60 DEG can be selected optionally. The machine having compact structure, small size, no pulling damage and no trace on the surface of the metal plate is suitable for folding and shearing miniature thin plates in small lot production.

Description

Table folding shearing machine

The utility model relates to a kind of metallic plate manual bending machine.

Existing manual squeezer generally than relatively large, has a support, and eccentric jam devices and the folding arm that flap is housed are housed on the support, and folding arm is by the pin bearing that is fixed on the support, and rotates around it.Folding arm one end is equipped with the stopping means that is made of dial, screw etc.Behind the Work-sheet pressing, pull the folding arm bending workpieces, for laborsaving, folding arm is done longlyer, and its other end is furnished with counterweight block.This squeezer relatively large metallic plate of bending that suits.For small-sized thin plate angle Support, the bending trouble that then seems, hard.If on vice or make simple and easy anchor clamps and carry out these thin plates of bending, could moulding and knuckle during when need bending several times less than 90 °, be difficult to guarantee the bending quality.

The purpose of this utility model is made improvement to above-mentioned squeezer exactly, provides a kind of small-sized, portable, can bending can shear the desk-top bending and shearing of small-sized sheet member again.

Technical solution of the present utility model is, respectively there is a bolster at two ends, folding arm top, diaxon is integral with one heart and with folding arm, flap is installed in the folding arm top, has U type groove on the support, and the folding arm bolster is inserted in the support U type groove, by the splicing sleeve supporting that is fastened on the support, and rotate around it, stopping means has a limited block to link to each other with the folding arm bolster, and rotates with the folding arm axle.

Scissors is equipped with in the support right back, and scissors is made of upper slitter and following cutter, and following cutter is fixed on the support, and upper slitter is hinged with following cutter.

Support also has the installation bottom outlet, and foundation mass can adopt stamping parts.

Above-mentioned bending and shearing operation principle is as follows: workpiece is placed on chock liner and the folding arm flap, depression of handle, eccentric jam devices drives downward workpiece pressing of pressing plate and self-locking, and at this moment the opposite side of compacted workpiece rotates together in company with folding arm, realize bending, the bending angle is limited by stopping means.Lift on the handle, unclamp workpiece, can be put on the scissors and shear, also can not cut.

The utility model makes compact integral structure because folding arm bolster and folding arm are integral, miniature portable.Scissors is housed on the machine, and bending, shearing are conveniently.Adjust stopping means, can select 120 °～60 ° bending angles.During bending, surface of the work does not have to be pulled and vestige.

Description of drawings

The desk-top bending and shearing general construction schematic diagram that Fig. 1, the utility model provide;

Fig. 2, the B-B of Fig. 1 analyses and observe;

Fig. 3, the K of Fig. 2 is to view;

Fig. 4, the support schematic diagram;

Fig. 1,2,3,4,5 has described the total structure of table folding shearing machine provided by the utility model and main modular construction schematic diagram. Scissors is made of upper cutter (1) and lower cutter (2), and upper cutter (1) is hinged by rivet and lower cutter (2), and take it as fulcrum, lower cutter (2) is fixed on the right back side of support (11) top, and upper cutter (1) presses down just can shear workpiece.

(4) be backing plate, be fixed on the support (11) of pressing plate (3) below, turn to plate (10) one ends and link to each other with pressing plate (3) that the other end and support (11) are hinged and take hinge as fulcrum. Fork (9) upper end is with to turn to plate (10) hinged, and lower end is enclosed within on the eccentric cover (8), and eccentric cover (8) is bearing on the support (11). Pulling handle (7), eccentric cover (8) make fork (9), turn to plate (10) moves up and down. More than each part consist of the eccentric device that compresses.

(5) be flap, be installed in folding arm (6) top, respectively there are a supporting axle (13), (14) in two ends, the left and right sides, folding arm (6) top, and diaxon with one heart and be integral. Have U-shaped groove (23) on the support (11), bottom outlet (22) is installed, be inserted in the U-shaped groove of support folding arm supporting axle (13), (14), and by splicing sleeve (12) supporting that is fastened on the support (11), folding arm (6) rotates around splicing sleeve (12) axis. (15) be dial, be carved with graduation mark (20) on it, a spacing block set (21) is arranged, have adjustment tank (18). Dial (15) is enclosed within on the folding arm supporting axle (14), and by screw (17) locking, spacing (16) interior square hole and folding arm axle (14) square toes (24) are tightly joined, and fix with screw, and spacing (16) are rotated with folding arm axle (14). (19) be the graduation indication line.

When needing to adjust the bending angle, unclamp screw (17), rotate dial (15) to required scale (angle), tighten screw (17), folding arm (6) rotates, and spacing (16) are along with rotation, when reaching graduation indication, spacing (16) are subjected to dial spacing block set (21) and stop, and folding arm (6) stops at the indicating graduation place, realize between 120 °～60 ° at bending angle optional.

The utility model provides an example.Referring to Fig. 1, the long 105mm of folding shearing machine, wide 90mm, high 130mm, but the bending width is below the 50mm, the metal sheet of thickness≤1.5mm, and it is long and high constant, and when width is 120mm, but the bending width is below the 80mm, the metal sheet of thickness≤1.5mm.
