Description

Technical Field

[0001] The utility model relates to the technical field of forging devices, in particular to a forging anvil. Background Art

[0002] Die forging is a forming method in which a metal blank in a red-hot softened state is placed into the die cavity of a die, and then the metal blank is forged with an air hammer or a hydraulic hammer to make it fit the inner wall of the die. Figure 3 It is a common die forging die, the upper side of which is open, and the lower side of which is provided with a demoulding hole. During forging, the metal blank is placed in the die, and an air hammer or a hydraulic hammer is used to forge it downward. After forging, the die is turned over so that the opening of the die is facing downward, and pads are placed on both sides of the lower part of the die to make the die suspended. Then, the ejector pin is inserted into the demoulding hole and the ejector pin is knocked downward with an air hammer or a hydraulic hammer to make the formed forging fall from the die. In actual operation, the two pads are manually clamped with pliers and placed on the anvil. Then The mold is then placed on the pad, which often results in the pad being placed inaccurately (for example, if the distance between the two is too small, the pad will be under the forging and cannot be demolded; if the distance between the two is too large, both sides of the mold cannot be supported at the same time). After the mold is placed, the mold needs to be raised and the position of the pad adjusted, which wastes time. In addition, when the pad is manually clamped with pliers and placed on the anvil, the pad sometimes falls off the clamp, and the pad that has fallen on the ground needs to be re-clamped and placed again, which also wastes time. Utility Model Content

[0003] The technical problem to be solved by the utility model is to provide a forging anvil in view of the above-mentioned technical deficiencies.

[0004] In order to solve the above technical problems, the technical solution adopted by the utility model is: a forging anvil, including a base, an upper anvil is arranged on the top of the base, guide plates are arranged on both sides of the upper anvil, guide holes are arranged on the guide plates, push-pull rods pass through the guide holes, and threaded portions are arranged on the push-pull rods. A nut located on the outside of the guide plate is threadedly connected to the threaded portion, and a pad is connected to one end of the push-pull rod located on the inside of the guide plate.

[0005] To further optimize the technical solution, an insertion portion is provided at one end of the threaded portion located on the inner side of the guide plate, a concave cavity is provided in the cushion block, and the bottom surface of the concave cavity is an opening; a hollow portion is provided at the lower part of the cushion block on the side close to the guide plate, the hollow portion is connected to the concave cavity and its bottom surface is an opening, the insertion portion is located in the concave cavity, the top surface of the concave cavity is higher than the top surface of the insertion portion, and the top surface of the hollow portion is lower than the top surface of the insertion portion.

[0006] To further optimize the technical solution, a handle is provided at one end of the push-pull rod away from the insertion portion.

[0007] To further optimize the technical solution, through holes are provided on both sides of the lower part of the guide plate, and threaded holes corresponding to the through holes are provided on the upper anvil. Bolts pass through the through holes and are connected with the threaded holes to fix the guide plate on the upper anvil.

[0008] Compared with the prior art, the utility model has the following advantages: 1. Guide plates are provided on both sides of the upper anvil, and the push-pull rods pass through the guide holes on the guide plates. The threaded portion on the push-pull rods is connected to the nut located on the outside of the guide plates, and the pad is connected to one end of the push-pull rod located on the inside of the guide plates, so that the pad can be quickly pushed to the correct position, which saves time; 2. The pad and the push-pull rod are detachably connected, so that pads of different specifications can be replaced according to different molds. In addition, since the top surface of the cavity is higher than the top surface of the insertion part, the insertion part will not be subjected to the downward force from the air hammer during demolding.

[0013] In order to make the purpose, technical solution and advantages of the utility model clearer, the utility model is further described in detail below in combination with specific implementation methods and with reference to the accompanying drawings. It should be understood that these descriptions are only exemplary and are not intended to limit the scope of the utility model. In addition, in the following description, the description of well-known structures and technologies is omitted to avoid unnecessary confusion of the concept of the utility model.

[0014] Specific implementation method: Combination Figure 1-3As shown, a forging anvil includes a base 1, an upper anvil 2 is arranged on the top of the base 1, guide plates 5 are arranged on both sides of the upper anvil 2, a guide hole is arranged on the guide plate 5, and the guide hole is a through hole, and a push-pull rod 3 passes through the guide hole, and a threaded portion 31 is arranged on the push-pull rod 3, and the diameter of the threaded portion 31 is slightly smaller than the diameter of the guide hole, and a nut 33 located on the outside of the guide plate 5 is threadedly connected with the threaded portion 31, and a cushion block 4 is connected with one end of the push-pull rod 3 located on the inside of the guide plate 5. By adjusting the position of the nut 33 on the threaded portion 31, when the nut 33 contacts the guide plate 5, the cushion block 4 is located in the correct position, that is, the distance between the two cushion blocks 4 is greater than the diameter of the forging and smaller than the outer diameter of the die 6, and when the die 6 of different specifications is replaced, the position of the nut 33 on the threaded portion 31 can be readjusted. When demoulding, the push-pull rod 3 is pushed inwards so that the nut 33 contacts the guide plate 5 to put the cushion block 4 in the correct position. After demoulding is completed, the push-pull rod 3 is pulled outwards so that the cushion block 4 contacts the guide plate 5, which saves time.

[0015] Furthermore, the threaded portion 31 is provided with an insertion portion 32 at one end located inside the guide plate 5, a cavity 42 is provided inside the cushion block 4, the bottom surface of the cavity 42 is an opening, a hollow portion 41 is provided at the lower part of the cushion block 4 close to the guide plate 5, the hollow portion 41 is connected to the cavity 42 and its bottom surface is an opening, the insertion portion 32 is located inside the cavity 42, the top surface of the cavity 42 is higher than the top surface of the insertion portion 32, the top surface of the hollow portion 41 is lower than the top surface of the insertion portion 32, and when the push-pull rod 3 is in a horizontal state, the top surface of the hollow portion 41 is higher than the top of the threaded portion 31, so that the bottom surface of the cushion block 4 can contact the upper anvil 2, and the insertion portion 32 will not be subjected to the downward force from the air hammer or hydraulic hammer during demoulding. In this way, the cushion block 4 and the push-pull rod 3 are detachably connected, and cushion blocks 4 of different specifications can be replaced according to the different molds 6.
