Description

Technical Field

[0001] The utility model relates to the technical field of sliding fork manufacturing, in particular to a pre-forging die for processing a light sliding fork. Background Art

[0002] The structure of the light sliding fork is a product with a wide and slender fork rod. The fork of the sliding fork is relatively wide. In order to meet the molding requirements of the sliding fork fork, it is necessary to select raw materials with a relatively large diameter; a billet with a diameter of 55mm is required to meet the fork molding, and the rod diameter of the light sliding fork is 36mm. The traditional sliding fork forging usually uses hammer forging and die forging. The transmission shaft sliding fork forging process designed according to the traditional method uses the same forging equipment. The process includes drawing and billet making-pre-forging-final forging-hot trimming. The mold is used in industrial production to obtain various molds and tools for the desired products by injection molding, blow molding, extrusion, die casting or forging molding, smelting, stamping and other methods. In short, the mold is a tool used to make molded objects. This tool is composed of various parts, and different molds are composed of different parts. It mainly realizes the processing of the shape of the object by changing the physical state of the molded material.

[0003] According to patent publication number CN205851767U, a pre-forging die for processing a light sliding fork includes an upper die block and a lower die block, with a pre-forging cavity for the sliding fork forging between the upper die block and the lower die block, the pre-forging cavity is composed of a rod cavity and two fork ear cavities that are interconnected, and a rebound push rod assembly for correcting the horizontal position of the sliding fork forging is provided in the rod cavity of the lower die block. In the pre-forging die of the utility model, a positioning groove for correcting the front and rear positions of the sliding fork forging and a rebound push rod assembly for correcting the horizontal position of the sliding fork forging are provided in the pre-forging cavity. The above structure enables workers to place the blank accurately into the pre-forging cavity of the forging die on the high-energy screw press, and at the same time, the blank is placed in an ideal horizontal state, which reduces the labor intensity of workers and can greatly improve work efficiency. The following problems exist in the prior art:

[0004] The existing pre-forging die cannot dissipate heat well during use, resulting in slow heat dissipation when completed, thereby affecting the manufacturing efficiency of the sliding fork; at the same time, the upper die and the lower die are inconvenient to disassemble during use.

[0017] By adopting the above technical solution, the locking and loosening functions are facilitated by the mutual cooperation of the push rod, the moving block and the screw rod.

[0018] Due to the adoption of the above technical solution, the utility model has achieved the following technical progress compared with the prior art:

[0019] The utility model provides a pre-forging die for processing a light sliding fork, which adopts the mutual cooperation of a pre-forging inner cavity, a copper sheet, a connecting piece, a heat sink, a fixing seat and a through opening. When the sliding fork in the pre-forging inner cavity is formed, the copper sheet absorbs heat on its surface, and the heat is transferred to the heat sink through the action of the connecting piece, and the heat is dissipated in the through opening through the action of the heat sink, so that the heat is discharged, thereby solving the problem of slow heat dissipation effect of the pre-forging die during use, achieving the phenomenon of heat dissipation, and improving the manufacturing efficiency of the sliding fork.

[0020] The utility model provides a pre-forging die for processing a light sliding fork, which adopts the mutual cooperation of a slide groove, a limit rod, a spring, a push rod, a moving block, a screw rod and a fixing part.

[0028] In this embodiment, when the internal sliding fork of the pre-forging inner cavity 11 is formed, the copper sheet 12 absorbs heat on its surface, and the heat is transferred to the heat sink 14 through the action of the connecting piece 13, and the heat is dissipated in the through hole 16 through the action of the heat sink 14, and the heat is discharged through the action of the through hole 16, and the connecting piece 13 is a good conductor of heat and can quickly transfer heat, and the internal structure of the upper mold 1 is the same as that of the lower mold 2. Example 2

[0029] like Figure 1-4 As shown, on the basis of Example 1, the utility model provides a technical solution: preferably, a slot 151 is opened inside the fixing seat 15, a guide rod 153 is inserted into the inside of the slot 151, one end of the guide rod 153 is fixedly connected to one end of the heat sink 14, one end of the heat sink 14 overlaps the surface of the fixing seat 15, and a rubber protrusion 152 is clamped on the upper surface of the guide rod 153.

[0030] In this embodiment, the guide rod 153 is squeezed and fixed by the rubber protrusion 152, so that the heat sink 14 is installed and fixed. The rubber protrusion 152 has a certain elasticity, and the guide rod 153 cannot transfer heat, so as to prevent the rubber protrusion 152 from being damaged by excessive heat. Example 3

[0031] like Figure 1-4 As shown, on the basis of Example 1, the utility model provides a technical solution: preferably, the interior of the fixed block 4 is fixedly connected with a fixing piece 41, the upper end of the fixing piece 41 extends to the interior of the locking block 3, the upper end of the fixing piece 41 is plugged into the interior of the locking block 3, a slide groove 31 is provided inside the locking block 3, the interior of the slide groove 31 is slidably connected with a limiting rod 32, the lower end of the limiting rod 32 is clamped with the upper end of the fixing piece 41, one side of the limiting rod 32 is fixedly connected with a spring 33, the surface of the limiting rod 32 is fixedly connected with a push rod 34, one end of the push rod 34 is movably connected with a moving block 35, the interior of the moving block 35 is movably connected with a screw 36, the surface of the screw 36 is movably connected to the interior of the locking block 3, and one end of the screw 36 is movably connected to the interior of the locking block 3.

When the upper mold 1 and the lower mold 2 need to be disassembled, the screw 36 is rotated in the opposite direction, thereby driving the moving blocks 35 on both sides to move to both sides and driving the push rod 34. Due to the action of the push rod 34, the limit rod 32 is pushed to move toward the inner wall and separate from the upper end of the fixing piece 41, and the spring 33 is driven to stretch, thereby completing the disassembly by taking the upper mold 1.
