Description

Technical Field

[0001] The utility model relates to the technical field of forging equipment, in particular to a device for punching and unloading flash of forgings. Background Art

[0002] Open die forging usually involves punching and trimming the flash after the die forging is completed. In a common punching die structure, after the punching is completed, the forging will fall onto the trimming die holder and then be removed by the operator. The punched-off flash will get stuck on the punch die and then rise with the equipment.

[0003] Small die forgings often use a stripper to remove flash stuck in the punch. The stripper is usually mounted on the die, and the operator uses pliers to pick up the forging and accurately place it into the trimming die.

[0004] Large die forgings are generally clamped and moved by manipulators due to their large size and weight. The conventional punching die stripper structure is limited by the space between the stripper plate and the trimming die, so the forging cannot be placed in the trimming die. Therefore, the stripper plate structure cannot be used to remove the flash stuck on the punch die. After the die forging flash is punched, the flash stuck on the punch die will affect the normal use of the punch die. Therefore, the operator needs to use a hand hammer to knock the flash off the punch die. The working environment of the forging is usually a high-temperature environment. Manual flash removal is labor-intensive and affects production efficiency. Utility Model Content

[0005] The technical problem to be solved by the utility model is to overcome the defects of the above-mentioned technology and provide a device for punching and unloading the flash of forgings.

[0006] In order to solve the above technical problems, the technical solution provided by the utility model is a device for punching and unloading the flash of forgings, including a trimming die, a connecting seat, a fixing bolt, a pin, a unloading claw, and a fixing plate. The trimming die is provided with at least one die cavity, and multiple connecting seats are respectively provided on the left and right sides of the trimming die. The top of each connecting seat is two integrally formed vertical rods, and the inner side of each vertical rod is provided with a connecting lug. The bottom of the unloading claw and the connecting lug are connected by a pin to form a structure.

[0007] Furthermore, the connecting seat and the side wall of the trimming die form a fixed connection structure through fixing bolts.

[0008] Furthermore, the connecting seat is arranged corresponding to the die cavity, and connecting seats are respectively provided on the left and right sides of the die cavity.

[0009] Furthermore, the vertical rod and the connecting lug are an integrally formed structure.

[0010] Furthermore, the bottom of the discharge claw is rotatably connected to the pin rod.

[0011] Furthermore, a fixing plate is provided between the inner side of the vertical rod and the outer side of the discharge claw, and two sides of the fixing plate are respectively in contact with the vertical rod and the discharge claw.

[0012] The advantages of the utility model compared with the prior art are that the device can adapt to various types of trimming equipment, and can automatically remove the flash after the flash of medium and large die forgings is punched, which can reduce the labor intensity of manual labor and improve production efficiency; at the same time, it reduces the chance of manual direct contact with high-temperature forgings and flash, reducing safety hazards.

[0016] The following is a detailed description of a device for blanking and unloading forging flash of the present invention in conjunction with the accompanying drawings.

[0017] In conjunction with the accompanying drawings, a device for punching and unloading flash of forgings includes a trimming die 1, a connecting seat 3, a fixing bolt 4, a pin 6, a unloading claw 7, and a fixing plate 8. The trimming die 1 is provided with at least one die cavity 2, and multiple connecting seats 3 are respectively provided on the left and right sides of the trimming die 1. The top of each connecting seat 3 is two integrally formed vertical rods, and the inner side of each vertical rod is provided with a connecting lug 5. The bottom of the unloading claw 7 and the connecting lug 5 are connected to each other through the pin 6.

[0018] As a preferred implementation scheme of this embodiment, the connecting seat 3 and the side wall of the trimming die 1 form a fixed connection structure through fixing bolts 4.

[0019] As a preferred implementation scheme of this embodiment, the connecting seat 3 is arranged corresponding to the die cavity 2, and the connecting seat 3 is provided on the left and right sides of the die cavity 2 respectively.

[0020] As a preferred implementation scheme of this embodiment, the vertical rod and the connecting lug 5 are an integrally formed structure.

[0021] As a preferred implementation scheme of this embodiment, the bottom of the discharge claw 7 is rotatably connected to the pin rod 6.

[0022] As a preferred implementation scheme of this embodiment, a fixing plate 8 is provided between the inner side of the vertical rod and the outer side of the discharge claw 7, and both sides of the fixing plate 8 are respectively in contact with the vertical rod and the discharge claw.

[0023] In the specific implementation of the present invention, the number of the die cavity 2 is usually one or two, and the connecting seats 3 are respectively provided on the left and right sides of the trimming die 1. The discharge claws 7 can rotate around the pin rod 6 within a certain angle. When the forging needs to be placed in the die cavity 2, the discharge claws 7 rotate outward to release the forging placement space, which is conducive to the smooth placement of the forging into the die.

[0024] After the forging is placed, the discharge claw 7 rotates inward, and the angle can be automatically adjusted according to the thickness and width of the burr, which can adapt to burrs of different shapes and sizes. In order to limit the rotation angle of the discharge claw 7, a fixing plate 8 is provided between the inner side of the vertical rod and the outer side of the discharge claw 7. The two sides of the fixing plate 8 are respectively in contact with the vertical rod and the discharge claw.

[0025] When the forging flash is cut, the punch of the forging punching equipment will rise with the flash, and the discharge claw 7 can hook the flash at the same time, pulling the flash down from the punch, so that the flash is separated from the die 2, and the flash is discharged;

[0026] After the flash is unloaded, the fixing plate 8 is removed, and then the unloading claw 7 is rotated outward. The operator uses pliers and a crowbar to remove the flash from the die 2 to complete the entire trimming operation.

[0027] The above description of the present invention and its embodiments is non-limiting. The drawings show only one embodiment of the present invention, and the actual structure is not limited thereto. In short, if a person skilled in the art is inspired by the above, and does not deviate from the purpose of the present invention, without inventive design, a structure and embodiment similar to the technical solution should fall within the scope of protection of the present invention.
