Description

Technical Field

[0001] This utility model relates to the field of cold heading machine technology, specifically to a quick-assembly die head mechanism for a cold heading machine. Background Technology

[0002] A cold heading machine is a device that cuts and cold-extrudes various processed metal wires (cold heading wires), so that the metal wires are cold-headed in a cold heading mold. It is used to process various standard and non-standard fasteners and automotive and motorcycle parts. Since a cold heading machine needs to process different types and sizes of workpieces, different fixed die heads need to be changed. For example, the utility model patent with publication number CN220992719U discloses a die head component for a cold heading machine, including a die body. The bottom of the die body is provided with a mounting plate, and the mounting plate has a cavity. The bottom of the mounting plate has multiple circular grooves, and a limiting post is fixedly connected to the inner wall of the top of the circular groove. The limiting post is in movable contact with the die head body. This utility model uses a circular block to move a pull rod, which in turn moves a moving block. The moving block then moves a moving rod that slides on a fixed rod. During the movement, the moving rod compresses a spring, and the moving block moves a locking rod, inserting a mounting block on the die head body into the cavity through a rectangular hole. Releasing the tension of the circular block causes the compressed spring to return to its original position. The spring, through the moving rod and the moving block, causes the locking rod to engage with the locking slot, thus fixing the die head body. No special tools are needed for assembly and disassembly, and the four locking rods ensure stability. However, replacing the die head body requires pulling the circular blocks on both sides, necessitating manual simultaneous pulling of the blocks on both sides, ultimately reducing the efficiency of die head assembly and disassembly. Therefore, we propose a quick-assembly die head mechanism for cold heading machines. Utility Model Content

[0015] 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.

[0016] Please see Figures 1-4 This utility model provides a technical solution: a quick-assembly die head mechanism for a cold heading machine, including a die body 1. The upper end of the die body 1 has an opening groove 3, which is connected to a placement cavity 2 opened on the die body 1. The placement cavity 2 is located below the opening groove 3. The upper end of the die body 1 is provided with a cover plate assembly 10. The lower end of the die body 1 has multiple evenly distributed through holes 7, each of which is connected to two symmetrically arranged limiting grooves 8 opened on the die body 1. The front end of the die body 1 has multiple evenly distributed first guide holes 5, and the rear end of the die body 1 has multiple evenly distributed second guide holes 6. A horizontal plate 4 is fixedly installed between the inner walls of the placement cavity 2. Each through hole 7 is slidably connected to a die head synchronous disassembly mechanism 9. The die head synchronous disassembly mechanism 9 is used to perform a double-sided synchronous insertion and tightening action on the die head body 91. The cover plate assembly 10 is used to close the placement cavity 2.

[0017] In this embodiment, the mold head synchronous disassembly mechanism 9 includes a mold head body 91. Fixing plates 93 are fixedly installed on both sides of the upper end of the mold head body 91. Each fixing plate 93 has an insertion hole 94 on its surface. An insertion post 95 is slidably connected to the inner wall of each insertion hole 94. A contact plate 96 is fixedly installed at one end of each two insertion posts 95 away from each other. A rack 97 is fixedly installed at the inner end of each contact plate 96. A rotating gear 911 meshes between the two racks 97. A guide post 98 is fixedly installed at the outer end of each rack 97. A limit plate 99 is fixedly installed at the outer end of the guide post 98. A spring 910 is fixedly installed at the rear end of the limit plate 99. The mold body 1 is fixedly installed at the rear end of the spring 910.

[0018] Specifically, when disassembling the mold head body 91, the limiting plate 99 can be pulled outward. At this time, the limiting plate 99 drives the front guide post 98 to slide within the first guide hole 5. The first limiting plate 99 drives the spring 910 to stretch. The front guide post 98 drives the front rack 97 to move outward. At this time, the front rack 97 drives the rotating gear 911 to rotate counterclockwise. At this time, the rotating gear 911 drives the rear rack 97 to move backward. Both racks 97 drive the contact plate 96 and the insertion post 95 to move outward. At this time, the insertion post 95 disengages from the insertion hole 94, and the mold head body 91 is released from its limiting position.

[0019] In this embodiment, the outer end of the front guide post 98 is slidably connected to the first guide hole 5, and the outer end of the rear guide post 98 is slidably connected to the second guide hole 6.

[0020] Specifically, it ensures that the guide post 98 can slide stably within the first guide hole 5 and the second guide hole 6.

[0021] In this embodiment, the cover plate assembly 10 includes a cover plate body 101, and each corner of the upper end of the cover plate body 101 is threaded with a locking bolt 102, and each locking bolt 102 is threaded with a mold body 1.

[0022] Specifically, when maintenance of the rotating gear 911 is required, the locking bolt 102 can be removed through the cover plate assembly 10, and then the cover plate body 101 can be removed from the mold body 1.

[0023] In this embodiment, limit strips 92 are fixedly installed on both sides of the mold head body 91, and each limit strip 92 is slidably connected to a limit groove 8 at its outer end.

[0024] Specifically, ensure that the mold head body 91 can initially align the vertical position of the insertion post 95 with the insertion hole 94 during installation.

[0025] In this embodiment, a follower shaft 912 is fixedly installed on the upper end of the rotating gear 911, and the upper end of the follower shaft 912 is rotatably connected to the horizontal plate 4 through a bearing.

[0026] Specifically, the rotating gear 911 can drive the follower shaft 912 to rotate when it rotates.

[0027] In this embodiment, the outer end of the mold head body 91 is slidably connected to the through hole 7.

[0028] Specifically, ensure that the mold head body 91 slides within the through hole 7 without interference.

[0029] Working principle: When disassembling the mold head body 91, the limiting plate 99 can be pulled outward. At this time, the limiting plate 99 drives the front guide post 98 to slide in the first guide hole 5. The first limiting plate 99 drives the spring 910 to stretch. The front guide post 98 drives the front rack 97 to move outward. At this time, the front rack 97 drives the rotating gear 911 to rotate counterclockwise. At this time, the rotating gear 911 drives the rear rack 97 to move backward. Both racks 97 drive the contact plate 96 and the insertion post 95 to move outward. At this time, the insertion post 95 disengages from the insertion hole 94, and the mold head body 91 is released from the limiting position.
