A forging press punch

Abstract

This utility model discloses a forging punch for a forging press, relating to the field of forging punch technology. It includes: a mounting base; a forging device, which is inserted and snapped into the interior of the mounting base; and an unlocking device, symmetrically and movably mounted on both sides of the mounting base, used to unlock the forging device by compression. This utility model utilizes the cooperation between the forging device and the unlocking device, employing an elastic support mechanism to provide bidirectional elastic support for the ejector mechanism and the bidirectional snap-fit ​​mechanism. When the punch presses down to process the workpiece, the workpiece overcomes the elastic force of the elastic support mechanism, causing the front end of the ejector rod of the ejector mechanism to retract into the punching rod, without affecting normal punching operations. After punching is completed, the elastic force of the elastic support mechanism pushes the front end of the ejector rod out of the punching rod, thereby pushing the waste workpiece generated during punching out of the through hole of the lower punching die, eliminating the need for manual cleaning by the operator.

Description

Technical Field

[0001] This utility model relates to the field of forging punch technology, and in particular to a forging punch for a forging press. Background Technology

[0002] In the fields of machinery manufacturing and metal processing, forging presses, as core processing equipment, are widely used in forming operations such as stamping and forging of workpieces. Among them, the forging punch is the key actuator for the forging press to realize the punching process of the workpiece. Its working principle is that the power of the forging press drives the forging punch to press down, which, together with the punching die, extrudes the metal workpiece, thereby forming a through hole that meets the design requirements on the workpiece.

[0003] Currently, the forging punches commonly used in the industry have a relatively simple structure, usually consisting of an integrated punching rod and a mounting base. The front end of the punching rod directly acts on the workpiece, and the punching operation is completed with the cooperation of the punching die.

[0004] However, discarded workpieces can easily clog the punching die, causing work interruptions. After the punch completes the punching of the workpiece, a columnar discarded workpiece (i.e., punching scrap) matching the size of the through hole is generated. This discarded workpiece is usually temporarily retained in the through hole of the punching die. Because traditional punches lack a dedicated scrap removal structure, the discarded workpiece is very likely to get stuck in the through hole of the punching die under its own weight and the squeezing action of metal debris during subsequent punching processes, forming a blockage. Once a blockage occurs, the operator must stop the forging press operation and manually clean the discarded workpiece from the through hole using tools. This not only interrupts the continuous processing flow and extends the production cycle, but may also damage the accuracy of the through hole of the punching die due to improper cleaning operations, thereby affecting the punching quality of subsequent workpieces and increasing equipment maintenance costs and processing error risks.

[0030] The technical effects and advantages of this utility model are as follows:

[0031] This invention utilizes the cooperation between the forging device and the unlocking device, and uses an elastic support mechanism to provide bidirectional elastic support for the ejector mechanism and the bidirectional locking mechanism. When the punch presses down to process the workpiece with the forging press, the workpiece overcomes the elastic force of the elastic support mechanism, causing the front end of the ejector rod of the ejector mechanism to retract into the stamping rod, without affecting the normal punching operation. After punching is completed, the elastic force of the elastic support mechanism pushes the front end of the ejector rod out of the stamping rod, thereby pushing the waste workpiece generated by punching out of the through hole of the punching die. This design effectively solves the problem of waste workpiece clogging the punching die due to the lack of a dedicated waste discharge structure in traditional punches. It eliminates the need for operators to stop work for manual cleaning, ensuring the continuity of forging and punching operations and avoiding production delays caused by work interruptions. The automatic ejection and waste discharge design eliminates the manual cleaning step, reduces manual intervention, and fundamentally avoids damage to the accuracy of the through hole of the lower die caused by cleaning operations.

[0039] 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.

[0040] This utility model provides, for example Figures 1-5 The forging punch of a forging press shown includes: a mounting base 100; a forging device 200, which is inserted and snapped into the interior of the mounting base 100; and an unlocking device 300, which is symmetrically and movably installed on both sides of the mounting base 100 and is used to unlock the forging device 200 by compression.

[0041] The forging device 200 includes: a punch rod 201, with a through slot inside the mounting base 100, the punch rod 201 engaging with the cavity of the through slot; an ejector mechanism 202, with a cavity inside the punch rod 201, the ejector mechanism 202 movably disposed inside the cavity; an elastic support mechanism 203, the ejector mechanism 202 movably engaging with one end of the elastic support mechanism 203; and a bidirectional locking mechanism 204, connected to one end of the elastic support mechanism 203, the bidirectional locking mechanism 204 being movably locked with the mounting base 100. The elastic support mechanism 203 provides bidirectional elastic support for the ejector mechanism 202 and the bidirectional locking mechanism 204. When the punch presses down to process the workpiece with the punch of the forging press, the workpiece will... The elastic force of the elastic support mechanism 203 causes the front end of the ejector rod 222 of the ejector mechanism 202 to retract into the stamping rod 201, without affecting the normal punching operation. After punching is completed, the elastic force of the elastic support mechanism 203 will push the front end of the ejector rod 222 out of the stamping rod 201, thereby pushing the waste workpiece generated by punching out from the through hole of the punching die. This design effectively solves the problem of waste workpiece clogging the punching die due to the lack of a special waste discharge structure in traditional punches. It eliminates the need for operators to stop work and manually clean, ensuring the continuity of forging and punching operations and avoiding production delays caused by work interruptions. The automatic ejection and waste discharge design eliminates the manual cleaning process, reduces manual intervention, and fundamentally avoids damage to the accuracy of the through hole of the die caused by cleaning operations.

[0042] Specifically, the ejector mechanism 202 includes: an inserting cylinder 221, which is movably disposed inside the cavity of the stamping rod 201 and is movably engaged with the elastic support mechanism 203; and an ejector rod 222, one end of which is fixedly connected to the inserting cylinder 221 and is slidably engaged with the stamping rod 201. The cylindrical design of the inserting cylinder 221 facilitates the insertion of the inserting rod 231, allowing for the movable engagement between the inserting rod 231 and the inserting cylinder 221. The ejector rod 222 facilitates the ejection of waste material. The elastic support mechanism 203 includes: an insertion rod 231, which is movably engaged with the insertion cylinder 221; and a spring 232, which is movably sleeved on the outside of the insertion rod 231. Through the movable engagement between the insertion rod 231 and the insertion cylinder 221, the linear movement of the insertion cylinder 221 and the slide block 241 is made more stable. The spring 232 facilitates the simultaneous elastic support of the insertion cylinder 221 and the slide block 241, while also achieving elastic locking and ejection of waste materials, making it more flexible to use. The bidirectional locking mechanism 204 includes: a slide block 241, which is slidably disposed inside the cavity of the stamping rod 201 and is fixedly connected to the insert rod 231; a bidirectional extrusion block 242, which is fixedly installed on the top of the slide block 241, and has first inclined surfaces on both sides; a locking block 243, which is slidably disposed on both sides of the stamping rod 201, and has a second inclined surface at the bottom of the locking block 243, the second inclined surface cooperating with the first inclined surface; and a slider 244, which is connected to the top of the locking block 243, and has a locking surface at the top of the cavity of the stamping rod 201. The slide groove and the sliding block 244 slide in the inner cavity of the slide groove. The first inclined surfaces on both sides of the bidirectional extrusion block 242 facilitate the simultaneous extrusion of the two clamping blocks 243, so that the clamping blocks 243 can be engaged into the inner cavity of the through hole of the mounting base 100, so as to realize the engagement between the clamping blocks 243 and the mounting base 100. The cooperation between the first inclined surface and the second inclined surface facilitates the adjustment of the direction of the force. Through the force component, the vertical movement of the bidirectional extrusion block 242 can promote the horizontal movement of the clamping blocks 243. Through the mutual cooperation between the sliding block 244 and the slide groove, the linear movement of the clamping blocks 243 is more stable.

[0043] The unlocking device 300 includes: a fixing ring 301, with through holes on both sides of the mounting base 100, and the fixing ring 301 fixedly installed inside the through holes; a pressing head 302, which is slidably inserted into the fixing ring 301; and a pressing head 303, which is fixedly connected to the end of the pressing head 302. The top of the pressing head 303 has a third inclined surface. The sliding insertion between the pressing head 302 and the fixing ring 301 facilitates the limiting of the sliding of the pressing head 302, preventing excessive sliding of the pressing head 303. The pressing head 303 facilitates the pressing of the locking block 243, causing the locking block 243 to be pressed into the interior of the stamping rod 201 for storage, so as to facilitate the disassembly of the forging device 200. The third inclined surface helps to prevent the protrusion of the pressing head 303 from affecting the disassembly of the forging device 200.

[0044] Finally, it should be noted that the above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
