Description

Technical Field

[0001] This utility model relates to the field of anti-jamming technology for wedges, and particularly to a device for preventing wedges from jamming. Background Technology

[0002] The wedge is an important component installed in the dovetail groove of the die holder in forging equipment. Its function is to prevent the forging die from coming out, loosening, and moving laterally. Conventional wedges and dovetail grooves have slopes in both the axial and radial directions. During assembly, the smaller end of the wedge enters the dovetail groove first, and then impacts the larger end, using the slope of the wedge itself to wed the die and die holder tightly.

[0003] During the production process, the wedge often fails to retract due to factors such as mold extrusion pressure, metal expansion caused by temperature, and increased friction. Utility Model Content

[0004] The purpose of this invention is to provide a device to prevent wedges from jamming, thereby solving the above-mentioned problems.

[0005] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a wedge anti-jamming device, including a dovetail groove of a mold base, a mold and a wedge body. A mold is provided on one side of the bottom of the dovetail groove of the mold base, and a wedge body is provided at the bottom of the dovetail groove of the mold base. An installation groove is provided inside the wedge body, and an anti-jamming component is provided inside the installation groove.

[0006] Preferably, the bottom of the anti-jamming component is fixed with a fixing block, and the fixing block has insertion holes on both sides inside, with fixing holes provided at the corresponding positions of the insertion holes, and the fixing holes are opened on the inner wall of the mounting groove.

[0007] Preferably, the mold is positioned and fixed by a dovetail groove in the mold base, which provides the installation position for the mold.

[0008] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0009] 1. The anti-jamming device for wedges provided by this utility model addresses the issue of wedges being difficult to remove due to strong static friction between the wedge body and the dovetail groove of the die base caused by die extrusion pressure, metal expansion, etc. After disassembling the anti-jamming component, external force is used to push the wedge body upwards, breaking the static friction balance and loosening the wedge body. Combined with the inclined structural characteristics of the wedge body and the dovetail groove of the die base in the axial and radial directions, the axial movement resistance is significantly reduced after the wedge body is radially loosened, allowing for easy axial removal. This design effectively solves the problem of wedges being difficult to remove in forging production, reduces damage to dies and equipment caused by wedge issues, and improves equipment lifespan and production efficiency.

[0010] 2. The anti-jamming device for wedges provided by this utility model involves installing anti-jamming components at appropriate positions on the large and small ends of the wedge body, with the components extending approximately 5mm above the top surface of the wedge body after installation. During assembly, the anti-jamming components enter the dovetail groove of the mold base along with the wedge body. After tightening, a gap is created between the top surface of the wedge body and the bottom surface of the dovetail groove of the mold base, effectively preventing increased friction due to excessive tightness. This fundamentally prevents the wedge from being unable to retract due to excessive friction, ensuring the normal use of the wedge during forging production, improving production stability and continuity, and reducing equipment failures and production stoppages caused by wedge jamming.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] To further understand the content of this utility model, a detailed description of this utility model will be provided in conjunction with the accompanying drawings.

[0017] Combination Figures 1 to 3 As shown, the anti-jamming device for the inclined iron of this utility model includes a dovetail groove 1 of the mold base, a mold 2 and an inclined iron body 3. The mold 2 is provided on one side of the bottom of the dovetail groove 1 of the mold base, and the inclined iron body 3 is provided at the bottom of the dovetail groove 1 of the mold base. An installation groove 4 is provided inside the inclined iron body 3, and an anti-jamming component 41 is provided inside the installation groove 4.

[0018] The bottom of the anti-jamming component 41 is fixed with a fixing block 42. The fixing block 42 has two holes 43 on both sides inside. The corresponding position of the holes 43 is provided with fixing holes 44, which are opened on the inner wall of the mounting groove 4.

[0019] The mold 2 is positioned and fixed by the dovetail groove 1 of the mold base, which provides the installation position for the mold 2.

[0020] Working principle:

[0021] Precisely insert the anti-jamming component 41 and its bottom fixing block 42 into the mounting slot 4, ensuring that the insertion hole 43 and the fixing hole 44 are perfectly aligned. Then, insert the fixing pin into the insertion hole 43 and the fixing hole 44. At this point, the anti-jamming component 41 will be securely installed inside the wedge body 3. Conversely, to disassemble, simply pull the fixing pin out of the insertion hole 43 and the fixing hole 44 to easily remove the anti-jamming component 41 from the mounting slot 4. By repeating this operation, the installation and removal of the anti-jamming component 41 can be conveniently achieved.

[0022] Install anti-jamming components 41 at appropriate positions on the large and small ends of the wedge body 3. After installation, the anti-jamming components 41 should protrude approximately 5mm above the top end face of the wedge body 3. During the assembly of the wedge body 3, the anti-jamming components 41 will enter the dovetail groove 1 of the mold base along with it. After the assembly is tightened in place, the anti-jamming components 41 will create a certain gap between the top end face of the wedge body 3 and the bottom surface of the dovetail groove 1 of the mold base, effectively preventing the friction from increasing due to excessive tightness, thereby preventing the wedge from being unable to retract due to excessive friction and achieving the function of isolation and friction reduction.

[0023] During the forging process, the wedge body 3 is affected by factors such as the extrusion pressure of the die 2 and metal expansion, resulting in strong static friction between it and the dovetail groove 1 of the die base, making it difficult for the wedge body 3 to retract. When this happens, first disassemble the anti-jamming component 41, and then use external force to push the wedge body 3 upward. The purpose of this operation is to break the balance of static friction between the wedge body 3 and the dovetail groove 1 of the die base. When the applied external force is greater than the static friction, the wedge body 3 will begin to loosen, changing from a static state to a state with a tendency to move relative to the die base.

[0024] Because both the wedge body 3 and the dovetail groove 1 of the mold base have slopes in both the axial and radial directions, when the wedge body 3 loosens in the radial direction, the constraint on the wedge body 3 in the axial direction will also decrease accordingly based on its own slope and the structural characteristics of the dovetail groove 1 of the mold base. Originally, the wedge body 3 was tightly constrained in both the radial and axial directions and difficult to move. After the radial direction loosens, the movement resistance in the axial direction is greatly reduced. At this time, applying force along the axial direction can easily remove the wedge body 3, making full use of the motion characteristics formed by the slope structure of the wedge body 3 and the dovetail groove 1 of the mold base, thus solving the problem of the wedge being difficult to remove.
