Abstract
The utility model discloses a percussion drilling sheet which comprises a drilling sheet body. The drilling sheet body is provided with a cutting top end for cutting and a connecting bottom end, connection between a percussion drilling bit and the connecting bottom end is kept, the cutting top end of the drilling sheet body is formed by a cutting tip, a left connecting blade part and a right connecting blade part, the left connecting blade part and the right connecting blade part are in transition connection with the cutting tip through arc-shaped concave faces, the cutting tip is formed by a front left cutting edge, a back left cutting edge, a front right cutting edge and a back right cutting edge in a connected mode, and a connecting edge between the front left cutting edge and the back left cutting edge and a connecting edge between the front right cutting edge and the back right cutting edge are respectively provided with at least one scrap separating groove. By means of the structure, the percussion drilling sheet is small in machining resistance and high in machining efficiency.
Description
Technical field
The utility model relates to a kind of percussion drilling plate.
Background technology
Percussion drilling plate is installed in the end of drill hammer conventionally for machining, percussion drilling plate have cutting top for cutting with for keeping with drill hammer the connection bottom being connected, but the cutting top of existing percussion drilling plate is directly intersected and is formed by left and right blade as shown in Figure 1, neither one is outstanding tip obviously, therefore to add the contact area of man-hour and work piece large for the percussion drilling plate of this structure, processing resistance is larger, and working (machining) efficiency is low.
Summary of the invention
For the deficiencies in the prior art, the utility model provides a kind of percussion drilling plate that resistance is less, working (machining) efficiency is higher of processing.
For achieving the above object, the utility model provides a kind of percussion drilling plate, comprise and bore sheet body, described brill sheet body have cutting top for cutting with for keeping with drill hammer the connection bottom being connected, the cutting top of described brill sheet body is by cutting tip and a left side, right connection blade forms, an and described left side, right connection blade is all connected by arc-shaped concave transition between tip with cutting, described cutting tip is by left front blade, left back blade, right front blade, right back blade connects and composes, and on the connection seamed edge between described left front blade and left back blade, and all offer at least one chip dividing groove on the connection seamed edge between described right front blade and right back blade.
The utility model can further be set to described left front blade and right back blade and be symmetrical set, and described left back blade and right front blade are symmetrical set.
The connection bottom that the utility model also can further be set to described brill sheet body is step-like.
The beneficial effects of the utility model are: adopt said structure, because the cutting top boring sheet body described in the utility model is to consist of cutting tip and left and right connection blade, therefore impact and add man-hour, mainly by cutting tip, contacted with work piece, greatly reduced contact area, make to process resistance force diminishes, working (machining) efficiency is improved, simultaneously, cutting tip connected by arc-shaped concave transition with left and right connection between blade, can effectively improve the integral hardness on percussion drilling plate cutting top, be conducive to extend the service life of percussion drilling plate.Separately, on the connection seamed edge between described left front blade and left back blade and on the connection seamed edge between described right front blade and right back blade, all offer chip dividing groove, the scrap that described chip dividing groove can make processing produce is divided into many segments, thereby be more discharged from more in time soon, further reduce to process resistance and improve working (machining) efficiency.
Accompanying drawing explanation
Fig. 1 is the front view of prior art;
Fig. 2 is front view of the present utility model;
Fig. 3 is top view of the present utility model.
The specific embodiment
Provided as shown in Figure 2,3 a kind of percussion drilling plate, comprise and bore sheet body, described brill sheet body have cutting top 1 for cutting with for keeping with drill hammer the connection bottom 2 being connected, the connection bottom 2 of described brill sheet body is step-like, can keep being connected with drill hammer better like this.The cutting top 1 of described brill sheet body is by cutting tip 11 and left connection blade 12, right connection blade 13 forms, and described left connection blade 12, right connection blade 13 is all connected by arc-shaped concave 14 transition between tip 11 with cutting, therefore impact and add man-hour, mainly by cutting tip 11, contacted with work piece, greatly reduced contact area, make to process resistance force diminishes, working (machining) efficiency is improved, simultaneously, cutting tip 11 and the left blade 12 that is connected, between right connection blade 13, by arc-shaped concave 14 transition, connect, can effectively improve the integral hardness on percussion drilling plate cutting top 1, be conducive to extend the service life of percussion drilling plate.Described cutting tip 11 is by left front blade 111, left back blade 112, right front blade 113, right back blade 114 connects and composes, described left front blade 111 and right back blade 114 are symmetrical set, described left back blade 112 and right front blade 113 are symmetrical set, on connection seamed edge between described left front blade 111 and left back blade 112, and on the connection seamed edge between described right front blade 113 and right back blade 114, all offer at least one chip dividing groove 115, the scrap that described chip dividing groove 115 can make processing produce is divided into many segments, thereby be more discharged from more in time soon, further reduce to process resistance and improve working (machining) efficiency.
