Wherein the contour of the spike 131 of each first staple blank 11 conforms to the contour of the cap 14 of the adjacent second staple blank 12, and the contour of the spike 131 of each second staple blank 12 conforms to the contour of the cap 14 of the adjacent first staple blank 11. Optionally, the staple blanks have a length of 30mm-60mm, and/or the angle of the staple tip 131 of each of the first staple blank 11 and the second staple blank 12 is 30 ° -40 °.
According to the production method of the composite wood gun nail provided by the embodiment of the invention, in the production process, because the outline of the nail tip 131 of the first nail blank 11 is attached to the outline of the nail cap 14 of the adjacent second nail blank 12, the composite board 1 can be completely cut into the first nail blank 11 and the second nail blank 12 through the processing technology at one time, and because the outline of the nail tip 131 of the first nail blank 11 is attached to the outline of the nail cap 14 of the adjacent second nail blank 12, the utilization rate of the composite board 1 is increased in the processing engineering, the production rate of the composite wood gun nail is further increased, and the resource utilization rate and the waste rate are reduced.
Wherein the length of each of the first and second nail blanks 11, 12 is 30mm-60mm, or the angle of the nail tip 131 of each of the first and second nail blanks 11, 12 is 30 ° -40 °.
Each of the first and second nail blanks 11, 12 has a length of 30mm-60mm, and the angle of the nail tip 131 of each of the first and second nail blanks 11, 12 is 30 ° -40 °.
When the lengths of the first nail blank 11 and the second nail blank 12 are less than 30mm, the phenomenon of loose connection is easily generated during use, and when the lengths of the first nail blank 11 and the second nail blank 12 are more than 60mm, the phenomenon of fracture is easily generated in the first nail blank 11 and the second nail blank 12. Preferably, the first staple blank 11 and the second staple blank 12 are 45mm in length.
When the angle of the nail tip 131 of the first nail blank 11 and the nail tip 131 of the second nail blank 12 is less than 30 °, the smaller the angle of the nail tip 131 is, the longer the length of the nail tip 131 portion is, and the longer the length of the nail tip 131 is, the lower the strength of the nail tip 131 is, with the diameters of the first nail blank 11 and the second nail blank 12 unchanged. Similarly, when the angle between the nail tip 131 of the first nail blank 11 and the nail tip 131 of the second nail blank 12 is greater than 40 °, it can be seen that the greater the angle of the nail tip 131, the smaller the penetration force of the nail tip 131 with the diameter of the first nail blank 11 and the diameter of the second nail blank 12 unchanged, and therefore, when the angle between the nail tip 131 of the first nail blank 11 and the nail tip 131 of the second nail blank 12 is 30 ° to 40 °, the first nail blank 11 and the second nail blank 12 have the advantages of high strength and strong penetration force. Wherein, the angle of the nail tip 131 refers to: the cross-section through the axis of the spike 131 is angled away from the apex of the post 132.
