Description

Technical Field

[0001] This utility model relates to the field of forging punches, and more specifically, to a forging punch. Background Technology

[0002] In the forging process, punches are the core components used for forging workpieces such as steel billets. Their conical ends are in direct contact with the workpiece and must withstand high-intensity impacts, friction and extrusion. After long-term use, they are prone to wear, deformation or even damage. Therefore, replacing the conical ends is a routine maintenance operation for punches. However, most existing punches adopt an integral structure design, that is, the cone end and the punch body are molded as one piece. When the cone end wears or deforms and needs to be replaced, the entire punch must be completely disassembled from the forging hammer and other equipment, which is wasteful of materials and cannot achieve partial separation of the cone end.

[0003] Announcement No. CN222957418U proposes a punch for punching forged steel billets. When the punch is in use, a heat absorption device is installed to avoid the impact of high temperature on the hardness of the punch, thereby improving the practicality, auxiliary function, and service life of the punch and reducing the occurrence of punch deformation. However, the tapered end is prone to wear and deformation during the forging and punching process. If the tapered end is damaged, the entire punch needs to be disassembled for replacement, which cannot achieve partial separation and results in significant waste of the extended end. Utility Model Content

[0004] The purpose of this invention is to solve the problems mentioned in the background art and to propose a forging punch.

[0005] The technical solution adopted by this utility model to solve its technical problem is: A forging punch includes an extended end and a tapered end, and also includes a mounting plate. The mounting plates are symmetrical and integrally molded on the extension end; The heat insulation board and the cone end are integrally formed, and the center of the heat insulation board and the center of the cone end are on the same straight line; Limiting components are respectively installed on the extension end and the heat insulation plate; The mounting plate and heat insulation plate are fastened with bolts, and the limiting component is equipped with a double elastic fastening component.

[0006] Furthermore, the limiting assembly includes a connecting plate, an insertion hole, and an insertion roller. Two sets of connecting plates are symmetrically welded on the extension end and located above the heat insulation plate. Each set includes two plates and each connecting plate has an insertion hole. Several rollers are welded to the heat insulation plate, and the rollers and the insertion holes correspond one-to-one with an interference fit.

[0007] Furthermore, the dual elastic fastening assembly includes a fixed plate, a pull roller, a limiting block, and a spring. The fixing plates are symmetrically welded onto the connecting plates; The pull roller slides in conjunction with the fixed plate, and a limit block is welded to one end of the pull roller; The spring is sleeved on the outside of the pull roller, with one end of the spring connected to the limit block and the other end of the spring connected to the fixed plate; The rollers are symmetrically provided with limiting grooves that are adapted to the limiting blocks.

[0008] Furthermore, the mounting plate and the heat insulation plate are provided with oppositely distributed connection holes, and fastening bolts are fitted into the connection holes.

[0010] Furthermore, the cone ends have different sizes, and each size of cone end corresponds to a heat insulation plate.

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model. The present utility model will be further described with reference to the accompanying drawings and embodiments: like Figures 1 to 3 As shown, the forging punch disclosed in this utility model includes two main components: an extended end 1 and a tapered end 2, as well as a mounting plate 11, a heat insulation plate 21, a limiting component, and a double elastic fastening component for connection and positioning. The specific structural design is as follows: Basic connection structure Mounting plate 11: It is integrally formed symmetrically on the outside of the extension end 1, serving as the core connecting carrier between the extension end 1 and the heat insulation plate 21; Insulation plate 21: integrally formed with the conical end 2, and strictly ensures that the center of the insulation plate 21 is collinear with the center of the conical end 2 (to ensure balanced force), and is fixedly connected to the mounting plate 11 by fastening bolts 13; Based on this, in order to further improve the heat insulation effect of the heat insulation board, the above-mentioned embodiment scheme is further optimized, such as... Figure 2 As shown, the interior of the heat insulation board 21 is filled with heat insulation material 201 (specifically, the heat insulation material 201 can be either aluminum silicate fiber cotton or silica aerogel felt).

[0015] (Connection details) Both the mounting plate 11 and the heat insulation plate 21 have connection holes that are aligned and matched in size (not shown in the figure). The fastening bolts 13 are inserted into the connection holes to achieve the initial fixation of the two. Limiting components (primary positioning) The limiting assembly is used to precisely define the assembly position of the extension end 1 and the heat insulation plate 21 to avoid assembly deviation. Specifically, it includes the connecting plate 12, the insertion hole, and the insertion roller 22. Two sets of connecting plates 12 are symmetrically welded to the surface of the extension end 1 and located above the heat insulation plate 21; each set of connecting plates 12 includes two parallel plates, and each plate has a hole. Several rollers 22 (the number of which corresponds to the number of insertion holes) are vertically welded to the side of the heat insulation plate 21 facing the extension end 1. During assembly, the rollers 22 and the insertion holes are interference-fitted to quickly complete the orientation calibration of the extension end 1 and the heat insulation plate 21. Double-elastic fastening assembly (secondary locking) To further enhance the connection's strength, a double elastic fastening assembly is added to the limiting assembly, including a fixed plate 31, a pull roller 32, a limiting block 33, and a spring 34. Fixed plate 31: Symmetrically welded to the outside of connecting plate 12, serving as the mounting base for the elastic component; The pull roller 32 is slidably engaged with the fixed plate 31. One end of the pull roller 32 is welded with a locking limit block 33, and the other end is welded with a pull handle for easy operation (shown in the figure, but not numbered). Spring 34: Sleeve on the outside of pull roller 32. One end of spring 34 is fixedly connected to limit block 33, and the other end is fixedly connected to fixed plate 31 (in the initial state, spring 34 is in a naturally extended state). (Locking Adaptation Structure) The side wall of the insertion roller 22 is symmetrically provided with a limiting groove 221 that is perfectly adapted to the size and shape of the limiting block 33. The limiting block 33 can be inserted into the limiting groove 221 to achieve vertical locking of the insertion roller 22. II. Optimized Design Scheme To further enhance the practicality and durability of the punch, the following optimizations were made to the basic design: Optimized heat dissipation performance Heat dissipation fins (not shown in the figure) are added above the heat insulation plate 21 to increase the heat dissipation area, accelerate the heat dissipation from the surface of the heat insulation plate 21, and avoid heat accumulation during the forging process from affecting the service life of the punch or the machining accuracy.

[0016] Adaptability optimization To meet the punching requirements of different workpieces, various sizes of tapered ends 2 are designed, and each size of tapered end 2 is equipped with a dedicated heat insulation plate 21 (the size of the heat insulation plate 21 is adapted to the tapered end 2), realizing modular replacement of one tapered end and one plate, and improving the adaptability of the punch to different processing scenarios. The working process of this utility model: 1. Conical end 2 selection Select the appropriate tapered end 2 according to the processing requirements (such as punching hole diameter and workpiece material): use the fine tapered end 2 for small hole diameter processing and the coarse tapered end 2 for large hole diameter processing; use the tungsten steel tapered end 2 for hard steel billet processing and the alloy steel tapered end 2 for ordinary steel billet processing. 2. Preliminary positioning and fixation Align the heat insulation plate 21 corresponding to the selected cone end 2 with the end face of the extension end 1, so that the insertion roller 22 on the heat insulation plate 21 is accurately inserted into the insertion hole of the connecting plate 12 of the extension end 1 (interference fit to achieve orientation limitation); at the same time, ensure that the connection surface between the heat insulation plate 21 and the extension end 1 avoids the placement port area of ​​the heat absorption device in the prior art, and avoids obstructing the water storage tank and the placement bottle (to ensure the normal function of the auxiliary device). After the roller 22 is inserted into place, the mounting plate 11 and the heat insulation plate 21 are connected by the fastening bolt 13 to complete the first position limitation. 3. Elastic locking (double fixation) Before the insertion roller 22 is inserted into the insertion hole, pull the handle to both sides to move the roller 32 and the limiting block 33 outwards synchronously. At this time, the spring 34 is compressed (away from the insertion path of the insertion roller 22). When the insertion roller 22 is fully inserted into the insertion hole and the limiting groove 221 on the insertion roller 22 is aligned with the position of the limiting block 33, release the handle. The spring 34 returns to its natural deformation and pushes the limiting block 33 into the limiting groove 221, completing the second position limitation. 4. Disassembly and Replacement Process When the cone end 2 shows wear or deformation and needs to be replaced, it is not necessary to disassemble the entire punch. The specific steps are as follows: First, remove the fastening bolts 13 connecting the mounting plate 11 and the heat insulation plate 21; Pull the handles to both sides to disengage the limiting block 33 from the limiting groove 221 on the insert roller 22; Simply separate the insert roller 22 from the insert hole to remove the old cone end 2 (including the matching heat insulation plate 21), replace the new cone end 2 assembly, and reinstall it according to the assembly process; This process does not require disconnecting the punch from the forging hammer, nor does it require disassembling the heat absorption device, protection device, or other peripheral auxiliary structures, significantly reducing downtime for maintenance and improving maintenance efficiency.
