Description

Technical Field

[0001] The utility model relates to the technical field of rod processing equipment, in particular to a processing device for a centering bracket. Background Art

[0002] With the increase of social urbanization, during the construction of industrial and civil buildings, there are more and more projects such as slopes, tunnels, and dams. The centering bracket is commonly used in building construction. Most centering brackets are in a U-shaped structure and are made by bending steel bars. At present, the conventional processing method of the centering bracket is that construction workers use a steel bar bending tool to bend the steel bars.

[0003] Chinese Utility Model Patent CN217749094U discloses a combined steel bar bending processing tool, including a connecting sleeve and a support rod. The front end of the support rod has a first cross bar and a second cross bar, and there is a gap for accommodating the steel bar between the first cross bar and the second cross bar; the steel bar can be inserted into the connecting sleeve. There is a gap for accommodating the steel bar between the first cross bar and the second cross bar. The steel bar is placed between the first cross bar and the second cross bar, and the steel bar is supported by the first cross bar and the second cross bar. The connecting sleeve is inserted into the steel bar, and then the connecting sleeve is pressed down to bend the end of the steel bar.

[0004] Although the steel bar can be easily bent by using this processing tool, it needs to be bent twice to form the centering bracket, and the positions between the two bends need to be measured, so the processing efficiency is relatively low. Therefore, it is necessary to provide a processing device for the centering bracket, which can solve the problem of relatively low processing efficiency of the existing steel bar processing tool when processing the centering bracket. Summary of the Invention

[0005] The purpose of the utility model is to provide a processing device for a centering bracket, which can solve the problem of relatively low processing efficiency of the existing steel bar processing tool when processing the centering bracket.

[0006] The utility model is realized as follows:

[0007] A processing device for a centering bracket includes a support frame, a pressing plate, a downward pressing assembly, and a limiting block; the support frame is a frame structure with a hollow top, the support frame is fixedly arranged on the working plane, a pair of limiting blocks are respectively arranged on both sides of the top of the support frame, and both ends of the steel bar are respectively inserted into the pair of limiting blocks, so that the steel bar is erected above the hollow part at the top of the support frame; one end of the downward pressing assembly is rotatably connected to one end of the top of the support frame, the pressing plate is arranged on the downward pressing assembly, and the width of the pressing plate is the same as the width of the centering bracket, so that when the downward pressing assembly rotates downward, the pressing plate can press against the steel bar and bend the steel bar at two places to form the centering bracket.

[0008] The described support frame includes support crossbars and support vertical bars. The support crossbars are U-shaped structures with one end open, and several support vertical bars are vertically connected to the bottom of the support crossbars. One end of the downward pressing assembly is rotatably connected to the closed end of the support crossbar, and a pair of limit blocks are respectively detachably installed on the side bars on both sides of the open end of the support crossbar.

[0009] The described downward pressing assembly includes a pressing rod, a connecting rotating shaft, and a connecting sleeve. A pair of connecting sleeves are respectively installed on both sides of the closed end of the support crossbar. Both ends of the connecting rotating shaft are rotatably inserted into the pair of connecting sleeves, and one end of the pressing rod is connected to the connecting rotating shaft. A pressing plate is arranged on the pressing rod.

[0010] The pressing rod includes a fixed rod and a hand-held rod. Several fixed rods are arranged at intervals along the length direction of the connecting rotating shaft and are perpendicularly fixed to the connecting rotating shaft. One end of the pressing plate is fixedly connected to the several fixed rods, and the other end of the pressing plate is fixedly connected to the hand-held rod.

[0011] A non-slip sleeve is sleeved on the hand-held rod.

[0012] The limit block is in a C-shaped structure, so that the end of the steel bar is installed in the hollow chamber of the limit block.

[0013] A limit rod is arranged between the side bars on both sides of the open end of the support crossbar. The two limit rods are arranged parallel to the steel bar and are arranged on the front and back sides of a pair of limit blocks.

[0014] A counterweight block is detachably connected to the support vertical bar.

[0015] Compared with the prior art, the present utility model has the following beneficial effects:

[0016] 1. Since the present utility model is provided with a pressing plate and a downward pressing assembly, the downward pressing assembly rotates to drive the pressing plate to press down on the steel bar. Since the width of the pressing plate is the same as the width of the centering bracket, the steel bar can be bent at both side ends of the pressing plate to form a U-shaped centering bracket. It can be formed in one bending without secondary bending and measurement. The processing efficiency and processing accuracy of the centering bracket are high. One or more centering brackets can be processed each time, and the centering bracket can be processed in a standardized manner.

[0017] 2. Since the present utility model is provided with a support frame, limit blocks, and counterweight blocks, a pair of limit blocks are used to pass through and limit the two ends of the steel bar, and the steel bar is erected on the support frame, which is convenient for the pressing plate to rotate downward to perform bending operations on two specified positions of the steel bar at the same time. At the same time, through the setting of the counterweight block, the setting stability and safety of the support frame during use are ensured, and tipping is avoided.

[0018] 3. Since the centering bracket of the present utility model is provided with a limiting block and a limiting rod, by using different installation positions of the limiting block and the limiting rod on the supporting cross bar, the pressing plate can exert different degrees of downward pressing effects on the steel bars between a pair of limiting blocks, so as to meet the processing requirements of centering brackets with different bending angles. The structure is simple, easy to operate, low in cost, and has a large scope of popularization and use. BRIEF DESCRIPTION OF THE DRAWINGS
