Description

Technical Field

[0001] This utility model relates to the field of metal bar processing technology, specifically a grooving mold for metal bar processing. Background Technology

[0002] In the grooving process of metal bars, most of the original grooving methods are done by wire cutting. Wire cutting mainly uses a moving metal wire as an electrode wire. The pulse electric spark discharge between the electrode wire and the workpiece generates high temperature to melt or vaporize the metal and form a kerf, thereby cutting out the part. However, wire cutting is a high-cost and low-efficiency method for grooving metal bars. In addition, some processing methods use a drawing machine and a grooving die to groove the metal bars.

[0003] Currently, most existing grooving dies are integral, so the number of grooving mechanisms on the grooving die is mostly fixed, and the grooving depth is also fixed. When facing the grooving requirements of different quantities and depths of metal bars, corresponding grooving dies need to be used. Since multiple different types of grooving dies need to be prepared when grooving metal bars, the cost of using metal bar grooving is relatively high. At the same time, after grooving, burrs will be generated on the groove edge of the metal bar. These burrs will affect the quality of the metal bar and need to be treated separately afterward, which affects the processing efficiency of the metal bar.

[0004] Therefore, this utility model provides a grooving die for processing metal bars to solve the above problems. Summary of the Invention

[0005] This invention provides a grooving die for processing metal bars, aiming to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a grooving mold for processing metal bars, comprising an installation mechanism, wherein the inner surface of the installation mechanism is provided with a grooving mechanism for grooving the metal bar, and the side wall of the installation mechanism is provided with a deburring mechanism for the groove edge of the metal bar; the installation mechanism includes an installation ring, wherein the inner surface of the installation ring is provided with a plurality of installation grooves, the installation grooves being of the same size and the installation grooves being convex in shape.

[0007] As a preferred technical solution of this application, a damping spring is fixedly installed on the inner wall of the mounting groove, and a damping plate is fixedly installed on one end of the damping spring. The outer surface of the damping plate is in contact with and slidably connected to the inner surface of the mounting groove.

[0008] As a preferred technical solution of this application, the grooving mechanism includes a grooving column, which is inserted into the installation groove, and the upper surface of the grooving column is provided with a placement groove.

[0009] As a preferred technical solution of this application, the lower surface of the slotted column is provided with a groove, the inner wall of the groove is provided with a through groove, a threaded rod is rotatably installed on the inner wall of the groove, one end of the threaded rod passes through the through groove and extends into the interior of the placement groove, and a limit rod is fixedly installed on the inner wall of the bottom surface of the placement groove.

[0010] As a preferred technical solution of this application, the grooving mechanism further includes a grooving cutter, the outer surface of which is slidably connected to the inner wall of the placement groove, the grooving cutter extending into the ring of the mounting ring, and the lower surface of the grooving cutter being provided with a threaded hole and a limiting hole.

[0011] As a preferred technical solution of this application, the outer surface of the threaded rod is threadedly connected to the inner wall of the threaded hole, and the outer surface of the limiting rod is slidably connected to the inner surface of the limiting hole.

[0012] As a preferred technical solution of this application, the deburring mechanism includes a fixing ring, the sidewall of the fixing ring is fixedly connected to the sidewall of the mounting ring by bolts, and a ring cutter is fixedly installed on the inner surface of the fixing ring, the diameter of the ring cutter being the same as the diameter of the mounting ring.

[0013] The beneficial effects of this utility model are as follows: In this utility model, the installation mechanism and the grooving mechanism can be disassembled, realizing the modular assembly of the grooving mold. Compared with the integral grooving mold, the modular grooving mold can increase or decrease the number of grooving mechanisms according to the number of grooves required for the metal bar. At the same time, the depth of the grooving blade in the grooving mechanism can be adjusted, thereby adjusting the grooving depth of the grooving mold, further improving the versatility and practicality of the grooving mold. During the grooving process, the grooving mold automatically removes the burrs generated when grooving the metal bar through the deburring mechanism, ensuring the grooving quality of the metal bar, while reducing the subsequent cleaning steps of the metal bar and improving the grooving efficiency of the metal bar.

[0017] 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.

[0018] This utility model provides a grooving die for processing metal bars, such as... Figures 1-5 As shown, a grooving mold for processing metal bars includes an installation mechanism 1. The inner surface of the installation mechanism 1 is provided with a grooving mechanism 2 for grooving the metal bar. The side wall of the installation mechanism 1 is provided with a deburring mechanism 3 for the groove edge of the metal bar. The installation mechanism 1 includes an installation ring 101. The inner surface of the installation ring 101 is provided with a plurality of installation grooves 102. The installation grooves 102 are of the same size and are convex in shape.

[0019] A damping spring 103 is fixedly installed on the inner wall of the mounting groove 102. A damping plate 104 is fixedly installed on one end of the damping spring 103. The outer surface of the damping plate 104 is in contact with and slidably connected to the inner surface of the mounting groove 102.

[0020] The grooving mechanism 2 includes a grooving column 201, which is inserted into the mounting groove 102. The upper surface of the grooving column 201 is provided with a placement groove 202.

[0021] The lower surface of the slotted column 201 is provided with a groove, the inner wall of the groove is provided with a through groove, and a threaded rod 204 is rotatably installed on the inner wall of the groove. One end of the threaded rod 204 passes through the through groove and extends into the interior of the placement groove 202. A limit rod 203 is fixedly installed on the inner wall of the bottom surface of the placement groove 202.

[0022] The grooving mechanism 2 also includes a grooving cutter 205. The outer surface of the grooving cutter 205 is slidably connected to the inner wall of the placement groove 202. The grooving cutter 205 extends into the ring of the mounting ring 101. The lower surface of the grooving cutter 205 is provided with a threaded hole and a limiting hole.

[0023] The outer surface of the threaded rod 204 is threaded to the inner wall of the threaded hole, and the outer surface of the limiting rod 203 is slidably connected to the inner surface of the limiting hole.

[0024] Through the cooperation of the above structures, according to the required grooving depth of the metal bar, the threaded rod 204 is rotated by a special tool. Under the action of the thread, the grooving cutter 205, in cooperation with the threaded hole, moves outward of the placement groove 202 under the limit of the limiting rod 203, thereby adjusting the height of the grooving cutter 205. Then, according to the number of grooves required for the metal bar, the grooving post 201 is inserted into the installation groove 102, so that the side wall of the grooving post 201 is in contact with the side wall of the shock absorber 104. The grooving cutter 205 is located inside the mounting ring 101. Then, the mounting ring 101 is placed in the mold mounting position of the drawing machine. One end of the metal bar is passed through the mounting ring 101 and fixedly connected to the drawing machine. During the process of the drawing machine pulling the metal bar, the grooving cutter 205 performs grooving on the metal bar. During the grooving process, the grooving mechanism 2 moves back and forth in the mounting groove 102 under the action of the damping spring 103 and the damping plate 104, so that the grooving mechanism 2 has a certain degree of mobility during the grooving process.

[0025] The deburring mechanism 3 includes a fixing ring 301. The side wall of the fixing ring 301 is fixedly connected to the side wall of the mounting ring 101 by bolts. A ring cutter 302 is fixedly installed on the inner surface of the fixing ring 301. The diameter of the ring cutter 302 is the same as the diameter of the mounting ring 101.

[0026] Through the cooperation of the above structures, after the metal bar is slotted by the grooving mechanism 2, the groove edge of the metal bar has certain burrs. After the metal bar passes through the hole of the ring cutter 302, the burrs on the groove edge of the metal bar are removed under the action of the ring cutter 302. As the ring cutter 302 is used for a longer period of time, the bolts are loosened, and the fixing ring 301 is separated from the mounting ring 101, so that the ring cutter 302 can be replaced to ensure the deburring effect of the metal bar.

[0027] Working principle: According to the number of slots required for the metal bar, the same number of slotting mechanisms 2 can be installed in the mounting slots 102 of the mounting mechanism 1. The deburring mechanism 3 is installed on the mounting mechanism 1 by bolts. Then, the mounting ring 101 is placed into the drawing machine. The slotting process of the metal bar is achieved through the cooperation of the drawing machine and the slotting mechanism 2.

[0028] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
