Description

Impact type manual hole puncher

Technical Field

The utility model relates to the technical field of punching tools, in particular to an impact type manual puncher.

Background

Punching is a technology commonly used in production and life, when objects such as plastics, thin-wall metal and the like are punched, the efficiency of punching by using a drilling mode is low, the punching quality is low when a hammer and a punching nail/cone are used for punching, a pipe is easy to damage when a tubular material is processed, and parts below a punched workpiece are easy to damage when the installed thin-wall metal is punched.

SUMMERY OF THE UTILITY MODEL

The utility model provides an impact type manual puncher which has the advantages that punching of thin-wall workpieces can be achieved quickly and conveniently, and punching quality is high.

The utility model aims to realize the technical scheme that the impact type manual hole puncher comprises a sleeve, wherein a spring, a striking hammer and a hole punching cutter are arranged in the sleeve, the hole punching cutter comprises a base positioned in the sleeve and a hole punching column extending out of the sleeve, the striking hammer is arranged between the spring and the hole punching cutter, a sliding groove extending along the axial direction of the sleeve is arranged on the side surface of the sleeve, and a wrench extending out of the sliding groove is arranged on the striking hammer.

Through the technical scheme, during the use, the post that will punch aligns the position that needs punch, through spanner pulling striking hammer compression spring, after the release spanner, the thrust of spring promotes the striking hammer to the sword quick travel that punches and final striking punching knife, the post that punches contacts and produces the impact with the work piece of waiting to punch, thereby realize punching, pass through the spring work of doing work at the in-process of punching, the difficult emergence offset of the in-process of punching, the high quality of punching, be applicable to the operation of punching of working of plastics or thin wall metalwork.

The utility model is further provided that the top of the chute is provided with a positioning clamping groove.

Through above-mentioned technical scheme, can fix through the draw-in groove when the spanner is pulled up to the topmost, can be used for waiting for the operation before the operation of punching is ready.

The utility model is further provided that the end part of the punching column is provided with a blanking groove.

Through above-mentioned technical scheme, set up the feed chute and make the bottom edge of perforating the post be sharp thin wall form, easily cut the work piece.

The punching device is further provided with a centering needle at the center of the punching column, and the centering needle is arranged in the blanking groove and extends out of the blanking groove.

Through above-mentioned technical scheme, be used for when punching to the heart needle with punch the post and aim at with the position of punching to improve the positioning accuracy that punches.

The utility model is further provided that the perforating column is in threaded connection with a positioning nut.

Through above-mentioned technical scheme, through rotating set nut, can adjust the distance that the sword removed in the sleeve punches to the adjustment is punched the degree of depth when punching, and is more convenient to use.

In conclusion, the utility model has the advantages of replacing the traditional pressing type or hammering type punching operation and improving the punching quality and the punching precision.

fig. 2 is a schematic cross-sectional view of an embodiment of the present invention.

In the figure, 1, a sleeve; 2. a spring; 3. striking a hammer; 4. a punching knife; 41. a base; 42. punching a hole column; 43. a centering needle; 44. a discharging groove; 5. a chute; 6. a wrench; 7. positioning a nut; 8. and a positioning clamping groove.

Detailed Description

The following detailed description of embodiments of the utility model refers to the accompanying drawings.

Example (b): referring to fig. 1-2, an impact type manual hole puncher comprises a sleeve 1, wherein a spring 2, a striking hammer 3 and a punching knife 4 are arranged in the sleeve 1, the punching knife 4 comprises a base 41 positioned inside the sleeve 1 and a punching column 42 extending out of the sleeve 1, the striking hammer 3 is arranged between the spring 2 and the punching knife 4, a sliding groove 5 extending along the axial direction of the sleeve 1 is formed in the side surface of the sleeve 1, and a wrench 6 extending out of the sliding groove 5 is arranged on the striking hammer 3. During the use, aim at the position that needs punch with the post 42 of punching, through 6 pulling hammering 3 compression springs 2 of spanner, release spanner 6 backs, spring 2's thrust promotes hammering 3 and final striking punching knife 4 to 4 quick travel of punching knife, post 42 of punching with wait to punch the work piece contact and produce the impact, thereby realize punching, do work through spring 2 at the in-process of punching, the difficult position skew that takes place of punching in-process, the high quality of punching, be applicable to the operation of punching of working of plastics or thin wall metalwork.

And a positioning clamping groove 8 is formed in the top of the sliding groove 5. The wrench 6 can be fixed by a slot when being pulled up to the topmost end, and can be used for waiting operation before the punching operation is ready.

The tip of perforating post 42 is equipped with blanking groove 44, sets up blanking groove 44 and makes the bottom edge of perforating post 42 be sharp thin-walled form, easily cuts the work piece.

The center position of 42 positions of the punching column is provided with a centering needle 43, the centering needle 43 is arranged in the blanking groove 44 and extends out of the blanking groove 44, and the centering needle 43 is used for aligning the punching column 42 with the punching position when punching is carried out, so that the punching positioning precision is improved.
