Embodiment 1

[0041] Such as Figure 6 , Figure 7 As shown, the double scissors include a base 1 , a lower scissors 2 fixed to the base 1 and an upper scissors shearingly matched with the lower scissors 2 .

[0042] The base 1 is provided with a fixing groove extending forward and backward, the lower scissors 2 are fixed in the fixing groove, and the lower scissors 2 is provided with a U-shaped groove 4 extending forward and backward. In this embodiment, the U-shaped groove 4 is a U-shaped through groove. The groove walls on the left and right sides of the U-shaped groove 4 are provided with placement grooves 5 extending left and right. The placement grooves 5 are semicircular grooves and the axes of the two placement grooves 5 are collinear. The U-shaped groove 4 is used for inserting the upper scissors from top to bottom. When the upper scissors are inserted into the U-shaped groove 4 from top to bottom, the upper scissors and the lower scissors 2 are sheared and matched to place the wo...

Abstract

The invention relates to a double-shear tool and a broken part taking-out tool for the double-shear tool. The double-shear tool comprises a base, a lower shear and an upper shear, the lower shear and the upper shear are fixed to the base, the lower shear is provided with a U-shaped groove, a containing groove for containing a workpiece is formed in the groove wall of the U-shaped groove, and the upper shear is inserted into the U-shaped groove from top to bottom, so that the upper shear and the lower shear are matched to shear off the workpiece. The double-shear tool further comprises an ejector block and a push rod, the top end of the ejector block is provided with a positioning groove used for making contact with the broken part clamped in the U-shaped groove, and the push rod is provided with a slope used for being matched with the ejector block in a pushing mode. And in the front-back moving process of the push rod, the slope surface of the push rod pushes the top block to vertically move upwards, so that the top block pushes the broken part clamped in the U-shaped groove upwards in the vertical direction. According to the double-shear tool, in the process that the broken part is jacked, the broken part moves upwards in the vertical direction, the rotating motion of the broken part is reduced, and then damage of the groove wall of the U-shaped groove to the fracture surface of the broken part is reduced.

Description

technical field [0001] The invention relates to a pair of scissors and a piece removal tool for the double scissors, belonging to the field of shear experiments. Background technique [0002] The double-shear test refers to the test method of using a double-scissor to cut the workpiece. The existing double-scissors such as figure 1 , figure 2 As shown, it includes a base 1, upper scissors 3 and lower scissors 2, the lower scissors 2 are fixed on the base 1, the lower scissors 2 is provided with a placement groove 5 for placing the workpiece 14, and the lower scissors 2 has a U-shaped groove 4 extending forward and backward , the U-shaped groove 4 is used for inserting the upper scissors 3. When the upper scissors 3 move downward, they cooperate with the lower scissors 2 to cut off the workpiece 14 by shearing force. The cut pieces are used for fracture analysis. The authorized announcement number is The Chinese invention patent of CN102998189B discloses the above-mentione...
