Description

Technical Field

[0001] The utility model relates to the technical field of molds, in particular to a forging and stamping combined mold for metal forgings. Background Art

[0002] A mold is a tool used to make shaped objects. This tool is composed of various parts, and different molds are composed of different parts. Forging molds are widely used when processing some metal workpieces. Forging molds are molds used in the forging process. The raw material undergoes plastic deformation in the forging mold under the action of external force, thereby obtaining parts of the required shape and size.

[0003] In this regard, China has applied for patent number CN202322536022.7, which discloses a metal forging stamping die assembly, comprising a base, a die body disposed at the top of the base, a punching hole disposed inside the die body, and limit springs fixedly connected to both sides of the die body. The metal forging stamping die assembly is provided with a mounting sleeve, a fixing bolt, a limit splint, a limit spring, and a second damper. When the punch and the punch need to be replaced, the fixing bolt is unscrewed from the inside of the fixing slot, thereby causing the mounting rod to lose its fixation. When the punch needs to be disassembled, the limit splint is pushed so that the limit splint squeezes the limit spring, thereby causing the punch to lose its fixation. When the punch and the punch lose their fixation, the punch and the punch can be disassembled, thereby facilitating the replacement of the punch and the punch into the desired shape. The structure is simple and flexible, and solves the problem of the inconvenience of disassembling and replacing the punch and the punch, which is relatively limited.

[0004] This combination mold can process raw materials through the cooperation of the punch and the punching hole, and is easy to assemble and disassemble. However, the punch and the punching hole are installed separately on the device, which is cumbersome. In addition, the punch and the punching hole are split structures, which are easy to mix up during storage, resulting in mold mismatch and affecting the user experience of the device.

[0005] Therefore, in order to solve the above problems, a metal forging forging stamping combined die is proposed. Utility Model Content

[0006] The purpose of the present utility model is to provide a metal forging forging and stamping combination die to solve the problem that the combination die in the prior art mentioned in the above background technology can process raw materials through the cooperation of the punch and the punch hole, and is convenient to assemble and disassemble, but the punch and the punch hole are installed separately on the device, which is more cumbersome, and the punch and the punch hole are split structures, which are easy to mix up when stored, resulting in mismatch of the die, which affects the user experience of the device.

[0007] To achieve the above-mentioned object, the present invention provides the following technical solutions: A metal forging forging and stamping combined die, comprising: a processing table, a cylinder assembly being installed on the top surface of the processing table;

A lower mold is clamped on the inner side of the fixed plate, and a punch is provided on the top surface of the lower mold. An empty slot is provided on the bottom surface of the lower mold. Guide rods are fixedly connected to the four corners of the top surface of the lower mold, and a movable plate is sleeved on the outer side of the upper end of the guide rod. The top surface of the movable plate is fixedly connected to a limiting sleeve, a punch is provided on the bottom surface of the movable plate, and a spring is fixedly connected to the top surface of the movable plate.

[0010] Preferably, the inner wall of the fixing plate is matched with the outer wall of the lower mold, and the positioning bolt passes through the fixing plate and is inserted into the inner side wall of the lower mold.

[0011] Preferably, the punched hole communicates with the interior of the empty slot, and the empty slot is aligned with the inclined slot in vertical alignment.

[0012] Preferably, the limiting sleeve is provided on the outside of the protruding end of the cylinder assembly, and the limiting sleeve is adapted to the cylinder assembly.

[0013] Preferably, the punch and the punch hole are aligned vertically and matched with each other.

[0014] Preferably, one end of the spring is fixedly connected to the upper end of the guide rod.

[0015] Compared with the existing technology, the beneficial effects of the present invention are: the present invention can connect the lower die and the movable plate together through the guide rod. When disassembling and assembling, it is only necessary to rotate the positioning bolt to realize the convenient disassembly and assembly of the lower die and the movable plate on the processing table. The operation is convenient, and the punch can punch holes to ensure matching, without the need for multiple trial fittings, thereby improving the user experience of the device.

[0016] The utility model is provided with a mold structure, and the movable plate is pressed downward, and the movable plate slides downward on the guide rod, so that the distance between the movable plate and the lower mold becomes smaller, and the movable plate stretches the spring when it moves, so that the lower mold and the movable plate can be placed on the inner side of the processing table, and the lower mold is installed on the inner side of the fixed plate. The fixed plate can clamp the lower mold on the outside, and the movable plate is released. The movable plate slides upward on the surface of the guide rod under the action of the spring, so that the guide rod moves upward away from the lower mold. When the movable plate moves, it drives the limit sleeve to be sleeved on the outer side of the protruding end of the cylinder assembly, so that the cylinder assembly and the movable plate can be released, and the positioning bolt is rotated, and the positioning bolt is threadedly connected to the fixed plate. When the bolt rotates, its end will be inserted into the side wall of the lower die, and the lower die can be further fixed to the inner side of the fixed plate, so that the lower die and the movable plate are stably installed on the device. The punch can punch holes to ensure matching, and there is no need for multiple trial matching, which improves the use experience of the device. The raw material is placed on the top surface of the punch hole, and the cylinder assembly is started. The cylinder assembly can push the limit sleeve to make the movable plate move downward on the guide rod. The movable plate is the tension spring, and the movable plate drives the punch downward to approach the punch hole. The punch cooperates with the punch hole to stamp the raw material, and the debris generated by the stamping can enter the empty slot through the punch hole and fall into the inclined slot through the empty slot, which is convenient for unified processing of the debris.

The inner side of the fixed plate 21 is clamped with a lower mold 23, and the top surface of the lower mold 23 is provided with a punching hole 24, and the bottom surface of the lower mold 23 is provided with an empty slot 25. The four corners of the top surface of the lower mold 23 are fixedly connected to a guide rod 26, and the outer side of the upper end of the guide rod 26 is provided with a movable plate 27. The top surface of the movable plate 27 is fixedly connected to a limiting sleeve 28, and a punch 29 is provided on the bottom surface of the movable plate 27. The top surface of the movable plate 27 is fixedly connected to a spring 210. The lower mold 23 and the movable plate 27 can be connected together through the guide rod 26. When disassembling, it is only necessary to rotate the positioning bolt 22 to realize the convenient disassembly and assembly of the lower mold 23 and the movable plate 27 on the processing table 1, which is convenient to operate, and the punch 29 can punch the holes 24 to ensure matching, without multiple trial matching, thereby improving the use experience of the device.

[0028] Furthermore, the inner wall of the fixed plate 21 is adapted to the outer wall of the lower mold 23, and the positioning bolts 22 pass through the fixed plate 21 and are inserted into the side wall of the lower mold 23. When the lower mold 23 is installed on the inner side of the fixed plate 21, it can remain stable. The positioning bolts 22 provide a connection for further fixing the lower mold 23 on the inner side of the fixed plate 21.
