Detailed Description
The present invention will be described in further detail with reference to the following embodiments and the accompanying drawings so that those skilled in the art can implement the invention with reference to the description.
Example 1
As shown in fig. 1 to 9, the present embodiment provides a hydraulic breaking hammer, which includes an upper cylinder and a lower cylinder, a drill rod cavity is provided in the lower cylinder, chamfers of visible portions of the upper cylinder and the lower cylinder on the surface of the hydraulic breaking hammer are both set to be an R angle, and a radius of the R angle is 1 to 15 mm. The chamfer angle of the visible part of the upper cylinder body and the lower cylinder body of the hydraulic breaking hammer is set to be a chamfer angle with the radius of 1-15mm, so that the stress at the position can be reduced, and the cracking phenomenon can be reduced.
The radius of the outer edge R angle 1 of the bottom of the lower cylinder body and the radius of the lateral edge R angle 4 of the lower cylinder body are 5-15 mm. The smaller the R angle, the more concentrated the stress, the higher the probability of stress damage, considering the structural integrity, the processing difficulty and the larger radial force the cylinder of the breaking hammer can bear, the R angle is not too large, the impact on the bottom and the outer edge of the lower cylinder is relatively large, so the radius of the R angle is properly increased.
The radius of the lower edge R angle 3 of the drill rod cavity at the bottom of the lower cylinder body and the radius of the opening edge R angle 2 of each functional hole on the side surface of the lower cylinder body are 1-10 mm. The side of the cylinder body, which is in contact with the internal parts, properly reduces the radius of the R corner at the inner side in order to reduce the entering of foreign matters considering that more foreign matters are splashed in the working environment.
The radius of the upper cylinder side edge R corner 6 is 3-10mm according to the degree of the external impact force on the position of the R corner. The radius of the outer edge R corner 5 at the top of the upper cylinder body is 1-10 mm.
Example 2
The embodiment provides a hydraulic breaking hammer, which comprises an upper cylinder body and a lower cylinder body, wherein a drill rod cavity is arranged in the lower cylinder body, chamfers of visible parts, located on the surface of the hydraulic breaking hammer, of the upper cylinder body and the lower cylinder body are respectively arranged to be R angles, and the radius of each R angle is 1-15 mm.
The visible parts of the upper cylinder body and the lower cylinder body, which are positioned on the surface of the hydraulic breaking hammer, are also coated with protective layers, and the protective layers can effectively reduce the impact of external force on the cylinder body.
While the embodiments of the invention have been described above, it is not intended to be limited to the details shown, or described, but rather to cover all modifications, which would come within the scope of the appended claims, and all changes which come within the meaning and range of equivalency of the art are therefore intended to be embraced therein.
