[0015] The specific implementation of the utility model is further described below in conjunction with the accompanying drawings.

[0016] like Figure 1-3 As shown, a hexagonal flange screw forming device includes a mounting frame 3, a bottom plate 4 and a top plate 5 are arranged on the mounting frame 3, a guide rod 6 is arranged between the bottom plate 4 and the top plate 5, a hydraulic cylinder 7 is arranged on the lower surface of the top plate 5, a cross plate 8 is arranged at the output end of the hydraulic cylinder 7, the cross plate 8 is slidably connected to the guide rod 6, and an upper mold cavity 9 for processing a hexagonal head is arranged on the lower surface of the cross plate 8, and also includes a forming groove 10 arranged on the mounting frame 3, the forming groove 10 is located between the bottom plate 4 and the upper mold cavity 9, and a mounting groove is opened on the forming groove 10, and the mounting groove A lower mold cavity 11 for processing the flange is installed inside, and mutually interpenetrating slide grooves are provided at the bottom of the lower mold cavity 11 and the bottom of the mounting groove. It also includes a mounting plate 12, which is arranged between the bottom plate 4 and the molding groove 10. The mounting plate 12 is slidably connected to the guide rod 6, and the two ends of the mounting plate 12 are respectively connected to the two ends of the cross plate 8 by elastic members 13. A push rod 14 is arranged on the upper surface of the mounting plate 12, and the push rod 14 is slidably connected to the slide groove. A clamping block 15 is arranged on the upper end of the push rod 14, and the clamping block 15 is located inside the lower mold cavity 11.

[0017] During extrusion molding, firstly heat one end of the metal rod 2 at high temperature, and then place it vertically into the lower die cavity 11 through pliers, with the end heated at high temperature located at the top. After placing the metal rod 2, start the hydraulic cylinder 7, and the output end of the hydraulic cylinder 7 drives the cross plate 8 to move downward, and the cross plate 8 drives the upper die cavity 9 to move downward. The guide rod 6 is provided to improve the stability of the cross plate 8 during movement. During the downward movement of the upper die cavity 9, it will abut against the upper end of the metal rod 2, and then the lower end of the metal rod 2 abuts against the block 15, pushing the block 15 and the push rod 14 to move downward. When the metal rod 2 cannot continue to move in the lower die cavity 11, the upper die cavity 9 continues to move downward, and through the cooperation of the upper die cavity 9 and the lower die cavity 11, the heated part of the upper end of the metal rod 2 is extruded and deformed, the part located in the lower die cavity 11 forms a flange, and the part located in the upper die cavity 9 forms a hexagonal head. Since the upper die cavity 9 moves downward at a fast speed, the rough blank of the hexagonal flange screw 1 can be quickly formed. After extrusion forming, the upper die cavity 9 moves upward following the hydraulic cylinder 7, and the cross plate 8 also moves upward synchronously. The cross plate 8 drives the mounting plate 12 to move upward through the elastic member 13. In the process of the mounting plate 12 moving upward, it drives the push rod 14 and the clamping block 15 to move upward, and the rough blank of the hexagonal flange screw 1 located in the lower die cavity 11 is ejected upward from the lower die cavity 11, but the rough blank of the hexagonal flange screw 1 cannot be completely ejected from the lower die cavity 11. When the upper surface of the mounting plate 12 abuts against the lower surface of the forming groove 10, the elastic member 13 is deformed, thereby not affecting the continued upward movement of the cross plate 8. When the cross plate 8 rises to the initial height, the rough blank of the hexagonal flange screw 1 is taken out of the lower die cavity 11 by pliers, and the unprocessed metal rod 2 is placed into the lower die cavity 11 at the same time.

[0018] Furthermore, when the lower surface of the block 15 abuts against the inner bottom surface of the lower mold cavity 11, the lower surface of the mounting plate 12 does not contact the upper surface of the bottom plate 4. When the hydraulic cylinder 7 pushes the metal rod 2 to move downward quickly, it can avoid collision between the mounting plate 12 and the bottom plate 4, which may cause damage to the push rod 14 and the block 15.

[0019] Furthermore, a ring plate 16 is provided at the upper end of the lower mold cavity 11, and a placement groove for accommodating the ring plate 16 is provided on the upper surface of the molding groove 10. The ring plate 16 and the molding groove 10 are connected by bolts, and the lower mold cavity 11 is fixed to the molding groove 10 by the ring plate 16 and the bolts, which facilitates the disassembly and replacement of the lower mold cavity 11.

[0020] Furthermore, a recessed groove is formed on the upper surface of the ring plate 16 , and the head of the bolt is completely located inside the recessed groove, so as to avoid the cross plate 8 and the bolt from being squeezed and causing damage to the bolt and the cross plate 8 .

[0021] Furthermore, the elastic member 13 is a tension spring, and the elastic member 13 always keeps a stretched state. When the metal rod 2 is squeezed, the tension spring is prevented from being bent and compressed, so as to improve the movement stability of the mounting plate 12 on the guide rod 6.

[0022] When the device is in use, the upper die cavity 9 moves upward, and the rough blank of the hexagonal flange screw 1 in the lower die cavity 11 can be pushed upward by a certain length through the push rod 14 at the same time, so that more of the rough blank of the hexagonal flange screw 1 can be exposed outside the lower die cavity 11, so that the staff can clamp it out of the lower die cavity 11 with pliers, thereby improving the convenience of clamping and achieving good use effect.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.
