Description

Technical Field

[0001] This utility model belongs to the field of forging die technology, specifically relating to a sliding insert forging die for a hydraulic press. Background Technology

[0002] Currently, hydraulic presses are one of the important pieces of equipment for producing large and medium-sized light alloy forgings. During the molding process, deformation occurs under static load, and integral forging dies are typically used. When developing a wide variety of forging products with small batch sizes or frequent changes, the extensive use of integral forging dies significantly increases production costs. Traditional insert forging dies, secured in a closed fixture using wedges or heat-shrink fittings, severely limit the projected area of ​​the die cavity to the size of the insert fixture, and are also time-consuming and labor-intensive to install and disassemble. Utility Model Content

[0003] The purpose of this invention is to provide a sliding insert forging die for a hydraulic press, so as to solve the shortcomings in the above-mentioned background technology.

[0004] To achieve the above objectives, this utility model provides the following technical solution:

[0005] A sliding insert forging die for a hydraulic press includes an upper insert, an upper insert pressure plate, an upper adjusting pad, a lower insert, a lower insert pressure plate, and a lower adjusting pad assembly. The upper insert has slide rails on its left and right sides and an upper guide post hole on its lower surface. A keyway is provided on the upper surface of the upper insert. A slider is provided on the inner side of the upper insert pressure plate. A keyway is provided on the lower surface of the upper adjusting pad. The upper insert, upper insert pressure plate, and upper adjusting pad are connected together to form an upper die. Similarly, the lower insert has slide rails on its left and right sides and a lower guide post hole on its upper surface. A keyway is provided on the lower surface of the lower insert. A slider is provided on the inner side of the lower insert pressure plate. A keyway is provided on the upper side of the lower adjusting pad. The lower insert, lower insert pressure plate, and lower adjusting pad are connected together to form a lower die.

[0006] As a further embodiment of this utility model, the upper adjusting pad and the lower adjusting pad are provided with the same keyway specifications.

[0007] As a further embodiment of this utility model, the upper adjusting pad is connected to the movable crossbeam of the hydraulic press.

[0008] As a further embodiment of this utility model, the lower adjusting pad is connected to the base of the hydraulic press.

[0009] As a further embodiment of this utility model, the upper insert, upper insert pressure plate, upper adjustment pad, lower insert, lower insert pressure plate, and lower adjustment pad are all made of H13 alloy mold steel.

[0010] As a further embodiment of this utility model, the upper insert and the upper insert pressure plate are fitted with a clearance fit.

[0011] As a further embodiment of this utility model, the lower insert and the lower insert pressure plate are fitted with a clearance fit.

[0012] Compared with the prior art, the advantages and beneficial effects of this utility model are:

[0013] 1. In this utility model, by using a sliding installation method, the area around the insert no longer needs more constraints. The size of the insert can be freely set according to the size of the forging product. The projected area of ​​the mold cavity is no longer restricted by the insert fixture. Many products that originally had to be forged using an integral forging die can be forged using an insert forging die, which can effectively reduce the manufacturing cost of the mold.

[0014] 2. In this utility model, by using a sliding installation method, it is no longer necessary to install and disassemble the insert mold fastened by wedges or heat sleeves, which can effectively improve labor productivity. Attached Figure Description
