Abstract

The cold bending tester includes energizing unit and bearing unit. The energizing unit includes a main cylinder piston rod and a bending core installed on the top of the main cylinder piston rod. The bearing unit includes adjustable blocking set and interference loading unit. The adjustable blocking set includes leading screw, and support rollers installed on two ends of the leading screw. A handle is connected to one end of the leading screw so that rotating the handle drives the leading screw rotating and brings two support rollers advance and retreat synchronistically. The interference-loading unit includes side directional loading oil cylinder, 5 inches template and antiwear pressure plate. Horizontal type structural design is adopted in the tester. It is convenient to adjust space between two support rollers in order to suit any sample. Maximum angle for bending work is 180 degrees. The invention saves manpower, and raises work efficiency.

Description

Technical field [0001] The invention relates to a double-station cold bending test machine, which belongs to metal material bending test equipment. Background technique [0002] As shown in Figure 1A and Figure 1B, most of the current steel bar cold bending testing machines are upright, including a force applying device and a force bearing device. The force applying device includes a hydraulic cylinder piston rod 1'and a piston rod 1'. The upper elbow 2'which has a certain diameter relationship with the sample 11', the said load-bearing device is two supporting rollers 3', during the test, the hydraulic cylinder applies force in the middle, and the piston rod 1'moves downwards , The bending center 2'contacts the sample 11', and the two rollers 3'do not move, forcing the sample 11' to bend until the sample 11' is transformed into 180°; as shown in Figure 1C, the piston rod 1'continues to move downwards Push out the sample 11' and take out the sample 11' to observe whether there ar...
