Description

Technical Field

[0001] The utility model relates to the technical field of upsetting machines, and more particularly to a steel bar upsetting machine. Background Art

[0002] In concrete building structures, mechanical connection of steel bars has the advantages of easy installation, fast connection and high joint performance. Steel bar upsetting straight thread connection is one of the important methods. It is achieved by axially cold upsetting the steel bar segment to expand the steel bar connection end, and then using a thread processing machine to process straight threads or tapered threads on the upsetting section. Finally, the two steel bars are connected together using a connecting sleeve with corresponding internal threads.

[0003] Existing steel bar upsetting machines generally use manual picking and placing of steel bars to complete the loading and unloading of the upsetting machine. During the manual picking and placing of steel bars, the upsetting machine is in a shutdown state, and the picking and placing takes a long time. When performing continuous upsetting processing on batches of steel bar segments, the processing efficiency of the upsetting machine will be reduced.

[0004] In view of this, the utility model proposes a steel bar upsetting machine capable of pre-loading and unloading steel bar segments to solve this problem. Utility Model Content

[0010] Furthermore, the surface of the upsetting plate is provided with concentric anti-skid grooves. By providing the concentric anti-skid grooves on the surface of the upsetting plate, side slippage between the steel bar segment and the upsetting plate can be prevented during upsetting.

[0029] It is worth noting that when using the steel bar upsetting machine, the steel bar segment is fitted into the upsetting cavity and placed inside the clamping groove 7 on the surface of the lower clamping jaw 6. The first hydraulic rod 3 is used to drive the upper clamping jaw 5 to move downward to clamp the steel bar segment, and then the second hydraulic rod 8 is extended to drive the upsetting plate 9 to move, thereby achieving the purpose of upsetting the steel bar segment.

[0030] The upper clamping jaw 5 and the lower clamping jaw 6 are both inserted into the surface of the connecting seat 4 , and the surface of the connecting seat 4 is threadedly connected with a positioning screw 19 for locking the upper clamping jaw 5 and the lower clamping jaw 6 .

[0031] By plugging the upper clamping jaw 5 and the lower clamping jaw 6 into the connecting seat 4 and disassembling the positioning screw 19, the upper clamping jaw 5 and the lower clamping jaw 6 can be replaced to meet the demand for stable clamping of steel bars of different sizes.
