Abstract
The invention discloses a cold-shearing machine which can decrease the deformation of a shearing part and a shear plane, and the invention comprises a machine base, a shearing base is arranged on the machine base, a shearing arm is arranged at the upper part of the shearing base, the middle part of the shearing arm is movably articulated on the shearing base, the end of the shearing arm is articulated with a push rod of a drive unit arranged on the machine base, and a hemicycle cutter blade port is arranged at the front part of the shearing arm and mutually matched with the hemicycle cutter blade port arranged on the shearing base. The invention is mainly used for shearing a variety of rods.
Description
Technical field
The present invention relates to the cold shears that is used to shear bar.
Background technology
Week known to the crowd is used to cut off the cold shears of bar, and its structure generally includes: support, and support is provided with Cut Block, and the top of Cut Block is provided with the shear arm that is driven by drive unit, and shear arm and Cut Block are provided with the shearing edge that cooperatively interacts.During actual the use, drive unit drives shear arm and makes rectilinear motion up and down, and the bar that is placed in the shearing edge is cut off.The shortcoming of this cold shears is: bar cut off the place and the shear plane deformation ratio more serious, will have influence on normally carrying out that the road processes behind the bar.
Summary of the invention
Technical problem to be solved by this invention is: a kind of cold shears that reduces to cut off place and shear plane deformation is provided.
For solving the problems of the technologies described above, the technical solution used in the present invention is: cold shears, comprise: support, support is provided with Cut Block, the top of Cut Block is provided with shear arm, the middle part of described shear arm is movably articulated on the Cut Block, and its end is hinged with the push rod that is arranged on the drive unit on the support, is respectively arranged with the semicircle shearing edge that cooperatively interacts on the front portion of shear arm and the Cut Block.
Above-mentioned drive unit is an oil cylinder.
The invention has the beneficial effects as follows: the present invention matches with the push rod that is hinged on the shear arm end with shearing edge between the Cut Block by shear arm, make shearing edge when shearing bar, at first bar is embraced, incision then, and in the incision process, shearing edge on the shear arm has a turn with respect to the bar surface, makes shearing become and is more prone to.Like this, the deformation of the place of cutting off of bar and shear plane reduces greatly, thereby has guaranteed normally carrying out of road processing behind the bar.
Description of drawings
Fig. 1 is a structural representation of the present invention;
Among the figure: 1, support, 2, cut off seat, 3, shear arm, 4, bearing pin, 5, drive unit, 6, push rod, 7, the push rod bearing pin, 8, bar.
The specific embodiment
Below in conjunction with accompanying drawing, describe specific embodiments of the present invention in detail.
As shown in Figure 1, cold shears of the present invention, comprise: support 1, support 1 is provided with Cut Block 2, the top of Cut Block 2 is provided with shear arm 3, the middle part of described shear arm 3 is movably articulated on the Cut Block 2 by bearing pin 4, and the end of shear arm 3 is hinged by push rod bearing pin 7 and the push rod 6 that is arranged on the drive unit 5 on the support 1, is respectively arranged with the semicircle shearing edge that cooperatively interacts on the front portion of shear arm 3 and the Cut Block 2.In the present embodiment, described drive unit 5 is an oil cylinder.
During use, bar 8 is shelved on the semicircle shearing edge of Cut Block 2, then, starting drive unit 5 is oil cylinder work, making that push rod is 6 extrapolated, drive shear arm 3 moves downward, moving downward in the process of shear arm 3, a pair of semicircle shearing edge between shear arm 3 and the Cut Block 2 is at first embraced bar 8, begin incision then, in the incision process of shear arm 3, shearing edge on the shear arm 3 has a turn with respect to the surface of bar 8, makes shearing become and is more prone to.Like this, the place of cutting off of bar 8 and the deformation of shear plane reduce greatly, thereby have guaranteed normally carrying out of bar 8 back road processing.
Claims (2)
1. cold shears, comprise: support, support is provided with Cut Block, the top of Cut Block is provided with shear arm, it is characterized in that: the middle part of described shear arm is movably articulated on the Cut Block, its end is hinged with the push rod that is arranged on the drive unit on the support, is respectively arranged with the semicircle shearing edge that cooperatively interacts on the front portion of shear arm and the Cut Block.
2. cold shears as claimed in claim 1 is characterized in that: described drive unit is an oil cylinder.
