Abstract

The utility model discloses magnetic steel straight hole type punching tongs, which belong to the field of a tool and can more conveniently perform manual tapping operation to a thin plate material at any time. The technical scheme of the magnetic steel straight hole type punching tongs is realized by comprising a handle, a tong shaft and a pressure spring; the other end corresponding to one end of the handle is provided with a left tong arm and a right tong arm; the left tong arm is of a Y shape from facing squarely, wherein the right side part is a compression bar arm provided with a round straight hole; the round straight hole is a compression bar hole and is formed by machining; the left side part is a press port arm which is provided with a press port by machining; the press port and the compression bar hole have the same diameter and are concentric; a sharp blade tip is machined at the left end of a round bar of which the diameter is appreciably smaller than that of the compression bar hole; more than a half of a spherical cavity is machined at the end face of the other end of the round bar and is used for internally placing an appreciably small steel ball, so that a compression bar is formed; the blade tip of the compression bar is penetrated into the compression bar hole leftwards and from right to left; and magnetic steel is machined on the right tong arm.

Description

Magnet steel straight hole formula punching nippers

Technical field:

The utility model belongs to instrument apparatus field, specifically is finger pressure hole pincers.

Background technology:

In many processing operations place, by the not so good operation of electric drill punching, also take electric power at thin plate (thick about about 0.1) thin soft as pattern more, could utilize the principle of work and power of pliers to come manual simply and easily punching, need to develop.

Summary of the invention:

The purpose of this utility model is the new technical scheme that a kind of pliers is provided, and it can satisfy above-mentioned needs preferably.

The technical solution of the utility model is to realize like this, it comprises handle, pincers axle, stage clip, the other end corresponding with handle one end is left clamp arm, right clamp arm, left clamp arm is faced and is fork-shaped, wherein the right side is divided into and is processed with the depression bar arm that circular straight hole is a strut kong, left part is to be processed with the pressure mouth arm of pressing mouth, presses mouth and strut kong concentric with the footpath; One compares smaller round bar processes at its left end and is processed with more than half spherical hollow space and cavity on sharp-pointed blade tip, the other end end face and is built-in with a smaller steel ball and becomes depression bar with aforesaid strut kong diameter, and depression bar blade tip end is left in right-to-left penetrates strut kong; Be processed with magnet steel on the right clamp arm.

The beneficial effects of the utility model be can be whenever and wherever possible to the thin plate attended operation of punching, very simple and convenient.

Description of drawings:

Fig. 1 is the whole half sectional view of punching nippers.

Among the figure, 1 is left clamp arm, and 2 is to press a mouthful arm, and 3 is to press mouth, and 4 are the material mouth, and 5 is the depression bar arm, and 6 is strut kong, and 7 is depression bar, and 8 is steel ball, and 9 is right clamp arm, and 10 for clamping axle, and 11 is stage clip, and 12 is magnet steel, and 13 is handle.

The specific embodiment:

The handle 13 of punching nippers, pincers axle 10 are same as handle, the pincers axle of steel wire pliers, and handled easily during for operation has installed between two handles and can make a handle open stage clip 11 automatically, as shown in Figure 1; The other end corresponding with handle one end is right clamp arm 9, left clamp arm 1, left clamp arm 1 is faced and is fork-shaped, wherein the right side is divided into and is processed with the depression bar arm 5 that the transverse circular straight hole is a strut kong 6, and left part is to be processed with to press mouthfuls 3 pressure mouth arm 2, press mouthful and strut kong concentric with the footpath; One compares smaller round bar processes at its left end and is processed with more than half spherical hollow space and cavity on sharp-pointed blade tip, the right-hand member end face and is built-in with smaller 8 one-tenth depression bars of steel ball 7 with the strut kong diameter, and depression bar blade tip end is left in right-to-left penetrates strut kong 6; On right clamp arm 9, be processed with the magnet steel 12 of sheet shape.Holding fixed handle 13 relies on middle, right clamp arm 9 by steel ball 8 to depression bar 7 exert pressure make press to left in its strut kong 6 on depression bar arm 5 over against pressure mouth arm 2 on pressure mouth 3, the thin plate material in the material mouthfuls 4 are just portalled by the blade tip end of depression bar 7 and the acting in conjunction die cut of pressing mouthfuls 3; The transmission operating pressure that steel ball up and down reciprocatingly rolls and coordinates at its inner face of the pressure lower edge of right clamp arm; The elastic force of finishing a punching press rear compression spring 11 unclamps the rear distraction handle in the power of holding and separates left and right sides tong arm, and depression bar 7 meetings this moment synchronous return under the powerful magnetic suction-operated of the magnet steel on the right clamp arm 9 12 is prepared against punching press next time.

Claims
