Technical Field

[0001] The utility model relates to the technical field of forming molds, in particular to a U-shaped part forming mold. Background Art

[0002] U-shaped parts are U-shaped parts, which are usually made of metal materials. U-shaped parts can provide greater tensile strength and shear strength, and are suitable for structures that need to withstand large tensile and shear forces. Therefore, the scope of use of U-shaped parts is also relatively wide, and they are often used to fix tubular objects or sheet objects.

[0003] U-shaped parts usually need to be processed and formed. During the processing, in order to ensure that they are formed into U-shaped parts, a forming mold is needed to assist in completing this work. However, if the mold is not well adapted during the forming process, it will easily affect the forming effect of the U-shaped part. Moreover, if the bottom of the part is in contact with the outside for a long time during its movement, it will easily cause greater wear and tear, affecting its service life. Utility Model Content

[0004] The purpose of the present utility model is to provide a U-shaped part forming die to solve the problem raised in the above background technology that if the mold is not well adapted during forming, the forming effect of the U-shaped part will be easily affected, and if the bottom of the mold is in contact with the mold for a long time during movement, it will easily cause greater wear and tear, thereby affecting the service life.

[0007] Preferably, the first embedding grooves are symmetrically distributed about the central axis of the base, the second embedding grooves are symmetrically distributed about the central axis of the base, and the third embedding grooves are symmetrically distributed about the central axis of the base.

[0008] Preferably, the diameter of the third ball is larger than the diameter of the second ball, and the diameter of the second ball is larger than the diameter of the first ball.

[0009] Preferably, side baffles are fixed on both sides of the base, and the side baffles are symmetrically distributed about the central axis of the base.

[0010] Preferably, front baffles are installed at the front and rear ends of the left and right sides of the base, a mounting groove is opened near the top of the front baffle, a connecting shaft is installed in the mounting groove, and the outer sleeve of the connecting shaft is connected to a limiting roller.

[0011] Preferably, a cylinder is installed on the top of the work frame, the bottom end of the cylinder is connected to a hydraulic telescopic rod, the bottom end of the hydraulic telescopic rod is installed with a connecting plate, and the bottom end of the connecting plate is fixed with an upper pressure module.

[0012] Preferably, the bottom end of the first embedding groove is connected to an adhesive layer, and the bottom end of the adhesive layer is adhesively connected to a rubber protective strip.

[0013] Compared with the prior art, the beneficial effects of the present invention are: the U-shaped piece forming mold not only improves the forming effect, but also improves the limiting ability and protection ability of the U-shaped piece forming mold;

[0014] (1) The pressure forming operation is performed by cooperating with two molding die bodies, and the workpiece is placed above the molding die bodies. The upper pressure module contacts the workpiece after pressing down, and then the two molding die bodies rotate accordingly after being pressurized. During the rotation, the first embedded groove and the third ball, the second embedded groove and the second ball, and the third embedded groove and the first ball cooperate to form rolling protection. After the molding die bodies move, the two molding grooves in the molding die bodies gradually become flush to form a U-shaped design, and the workpiece gradually contacts the two molding grooves fully, thereby improving the overall molding effect during the working process;

[0015] (2) By installing the side baffles on both sides of the base, the side baffles form side limit protection, and at the same time, the front baffle is fixed at the front and rear positions of the base, and a mounting groove is opened near the top of the front baffle, and the sleeve connection between the front baffle and the limit roller is completed by the connecting shaft. Therefore, after the main body of the forming mold is pressurized and moved, a certain front and rear limit protection is formed, thereby better improving the overall limit capacity during the working process;

[0016] (3) The upper pressure module performs pressure forming by starting the cylinder to drive the hydraulic telescopic rod to extend and retract during operation. When the upper pressure module contacts the workpiece, the bottom of the upper pressure module is bonded to the rubber protective strip using an adhesive layer. Therefore, when pressure is applied to the workpiece, the rubber protective strip forms pressure protection, thereby reducing the hard wear on the workpiece during operation and improving the overall protection capability.
