Description

Technical Field

[0001] This utility model relates to the technical field of pipe bending forming, and in particular to a cold-pressed pipe bending forming equipment. Background Technology

[0002] The preparation of bent pipes is divided into cold pressing and hot pressing. Cold-pressed bent pipes are generally produced by pipe bending machines disclosed in utility model patents such as CN204724656U and CN203459483U.

[0003] However, during use, it was found that the existing cold bending machine is not convenient for efficiently bending large-diameter, thick-walled pipes, resulting in poor practicality. Therefore, there is an urgent need for a cold-pressed pipe bending forming equipment to improve the above problems. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a cold-pressed pipe bending forming equipment that places the pipe in a forming mechanism, applies pressure to the forming mechanism through a pressure applying mechanism, and causes the forming mechanism to squeeze the pipe, thereby forming a bent pipe, thus improving the practicality of the equipment.

[0005] This utility model discloses a cold-pressed pipe bending forming equipment, which includes a pressure applying mechanism and a forming mechanism, which is installed on the pressure applying mechanism.

[0006] The pressure-applying mechanism provides pressure to the forming mechanism, which then bends the pipe.

[0007] The pipe is placed in the forming mechanism, and pressure is applied to the forming mechanism by the pressure applying mechanism, which squeezes the pipe and then bends it, thereby improving the practicality of the equipment.

[0008] Preferably, the forming mechanism includes a bottom mold, multiple sets of bases, a top mold, multiple sets of mounting plates, and a guide mechanism. The multiple sets of bases are all installed on the bottom of the bottom mold, the guide mechanism is installed on the bottom mold, and the multiple sets of mounting plates are all installed on the top mold. The pipe is placed on the guide mechanism, and the top mold is driven to descend by the pressure application mechanism to squeeze the pipe and extend into the bottom mold until the pipe is pressed into a bend with the required curvature, thereby improving the practicality of the equipment.

[0009] Preferably, the guiding mechanism includes two sets of support wheels and multiple sets of support shafts, and the top of the bottom mold is provided with multiple sets of limiting grooves; the multiple sets of support shafts are respectively inserted into the multiple sets of limiting grooves, and then the pipe is placed on the top of the two sets of support wheels. During the pressing process of the top mold on the pipe, the two sets of support wheels rotate and cooperate with the top mold to bend the pipe, thereby improving the practicality of the equipment.

[0010] Preferably, the length of each set of support shafts is greater than the wall thickness of the bottom mold; this facilitates the movement of the support wheels using a forklift.

[0011] Preferably, the bottom mold is provided with support plates at both the front and rear ends to facilitate the movement of the bottom mold by forklift.

[0012] Preferably, the pressure applying mechanism includes a base, a gantry frame, a hydraulic cylinder, and a lifting platform. The gantry frame is installed on the base, the hydraulic cylinder is installed on the top of the gantry frame, and the lifting platform is installed on the bottom of the hydraulic cylinder. The bottom mold is placed on the base, the top mold is installed on the bottom of the lifting platform, and the pipe is placed on two sets of support wheels. By extending the hydraulic cylinder, the top mold, in conjunction with the two sets of support wheels, bends the pipe, thereby improving the practicality of the equipment.

[0013] Preferably, the gantry frame is equipped with guide rails, and the side end of the lifting platform is slidably connected to the guide rails; the guide rails guide the lifting platform, thereby improving the stability of the lifting platform.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: the pipe is placed in the forming mechanism, and the forming mechanism is pressured by the pressure applying mechanism, so that the forming mechanism squeezes the pipe and then bends it, thereby improving the practicality of the equipment.
