Description

Technical Field

[0001] This utility model relates to a ring punching machine, specifically a ring punching machine that facilitates die replacement. Background Technology

[0002] A ring punching machine (also known as a rubber ring punching machine or a punching and binding machine) punches holes in documents to be bound before binding. However, since paper comes in different sizes and the binding requirements and needs of different sizes are not the same, different punching machines are needed to punch and bind to meet production needs. This results in a large variety of punching machines required, higher costs, and larger space requirements.

[0003] Furthermore, if the die in an existing ring punching machine is damaged during use and needs replacement, the entire machine must be disassembled, which is cumbersome and can easily lead to damage if the user is unfamiliar with the equipment. Therefore, this paper proposes a ring punching machine that facilitates die replacement. Utility Model Content

[0004] The purpose of this invention is to provide a punching machine for pressure rings that facilitates die replacement in order to solve the above problems.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a pressure ring punching machine that facilitates die replacement, comprising a machine base; characterized in that it further comprises a detachable die mechanism mounted on the machine base and a guide limiting frame disposed on the machine base to guide and limit the die mechanism's mounting on the machine base; the die mechanism comprises a die holder, a fixed rod mounted on the die holder, a die holder elastically mounted on the fixed rod, a plurality of punches mounted on the die holder and slidably connected to the die holder, and a detachable die-pressing component mounted on the die holder for pressing the plurality of punches onto the die holder.

[0006] A further preferred embodiment includes a spring fitted onto the fixing rod and positioned between the tool holder and the tool post.

[0007] Further preferably, it also includes a limiting nut installed on the upper end of the fixing rod and an 8-shaped hole provided on the pressure knife member. The 8-shaped hole includes a fixing hole with a diameter smaller than that of the limiting nut and a disassembly hole that communicates with the fixing hole and has a diameter not smaller than that of the limiting nut.

[0008] A further preferred embodiment includes a boss at one end of the pressing member to facilitate pulling the pressing member, and a limiting platform at the other end of the pressing member to limit the position of the pressing member on the tool holder.

[0009] A further preferred embodiment includes a pressing end located at one end of the tool holder, which facilitates pressing the tool holder to move downwards, causing the limiting platform to be misaligned with one end of the tool holder.

[0010] More preferably, the guide limiting frame includes a guide base frame installed on the machine base to guide and limit the tool holder, and a guide top frame to limit and guide the tool holder.

[0011] A further preferred embodiment includes a limiting seat mounted on the machine base, a limiting member movably mounted within the limiting seat and partially protruding from the limiting seat, a second spring disposed within the limiting seat, and a limiting hole disposed on the tool holder corresponding to the limiting member.

[0012] More preferably, the limiting member is a spherical member or a limiting post with a spherical top.

[0013] The beneficial effects of this utility model are as follows: By setting a detachable die-cutting mechanism, different die-cutting mechanisms can be selected and replaced according to actual needs. The base of a ring punching machine can achieve different functions by directly replacing the die-cutting mechanism. There is no need to configure a corresponding ring punching machine for each type.

[0027] The following description, in conjunction with the accompanying drawings, further illustrates the present invention of a pressure ring punching machine that facilitates die replacement.

[0028] It should be noted that all directional indicators such as up, down, left, right, front, back, etc. in the embodiments of this utility model are only used to explain the relative positional relationship and movement of the components in a specific posture as shown in the attached figure. If the specific posture changes, the directional indicator will also change accordingly.

[0029] In this utility model, unless otherwise explicitly specified and limited, the terms "connection," "fixing," etc., should be interpreted broadly; for example, "fixing" can mean a fixed connection, a detachable connection, or an integral part; it can mean a mechanical connection; it can mean a direct connection or an indirect connection through an intermediate medium, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0030] See Figures 1-11 As shown, a pressure ring punching machine that facilitates die replacement includes a machine base 1; it is characterized by further including a detachable die mechanism 2 mounted on the machine base 1 and a guide and limiting frame 3 disposed on the machine base 1 to guide and limit the installation of the die mechanism 2 on the machine base 1; the die mechanism 2 includes a die holder 21, a fixing rod 22 mounted on the die holder 21, a die holder 23 elastically mounted on the fixing rod 22, a plurality of punches 24 mounted on the die holder 23 and slidably connected to the die holder 21, and a detachable die-pressing member 25 mounted on the die holder 23 for pressing the plurality of punches 24 onto the die holder 23;

[0031] With the detachable die-cutting mechanism 2, different die-cutting mechanisms 2 with different punches 24 can be selected and replaced according to actual needs. The base 1 of a ring punching machine can achieve different functions by directly replacing the die-cutting mechanism 2. There is no need to configure a corresponding ring punching machine for each type. The disassembly and assembly operation is simple and quick, and the cost is low.

[0032] With the setting of the die-cutting mechanism 2, during use, several punches 24 can be installed or removed according to the required interval and quantity of punching. When a punch 24 is damaged, it only needs to be replaced, without replacing the entire die-cutting mechanism 2. Furthermore, when performing disassembly, assembly, and maintenance on the die-cutting mechanism 2, it is not necessary to disassemble the entire ring punching machine.

[0033] In one embodiment, a spring 26 is also included, which is fitted onto the fixed rod 22 and located between the tool holder 21 and the tool post 23. The spring 26 allows the tool post 23 to be elastically and movably mounted on the fixed rod 22, providing spring support and buffering for the movement of the tool post 23.

[0034] In one embodiment, the device further includes a limiting nut 4 installed on the upper end of the fixing rod 22 and a figure-eight hole 41 provided on the pressing member 25. The figure-eight hole 41 includes a fixing hole 42 with a diameter smaller than that of the limiting nut 4 and a disassembly hole 43 communicating with the fixing hole 42 and having a diameter not smaller than that of the limiting nut 4. With the setting of the limiting nut 4 and the fixing hole 42 and the cooperation of the spring 26, the spring 26 pushes the tool holder 23 upward. The tool holder 23 exerts an upward thrust on the pressing member 25. The pressing member 25 is limited and pressed on the tool holder 23 by the limiting nut 4, thereby pressing several punches 24 onto the tool holder 23.

[0035] With the installation and removal hole 43, when the pressure knife 25 is removed from the tool holder 23, the pressure knife 25 is pushed so that the installation and removal hole 43 on the pressure knife 25 moves to the limit nut 4. The diameter of the installation and removal hole 43 is not less than the diameter of the limit nut 4. At this time, the pressure knife 25 can be removed from the tool holder 23. After the pressure knife 25 is removed, the punch 24 can be replaced.

[0036] In one embodiment, it further includes a boss 5 provided at one end of the pressing member 25 to facilitate the pulling of the pressing member 25 and a limiting platform 51 provided at the other end of the pressing member 25 to limit the position of the pressing member 25 on the tool holder 23.

[0037] By setting the limiting platform 51, when disassembling the pressure knife 25, the boss 5 facilitates the pulling of the pressure knife 25 to move it, so that the disassembly hole 43 on the pressure knife 25 can be moved to the limiting nut 4 for disassembly.

[0038] The limiting platform 51 limits the position of the pressing tool 25 on the tool holder 23.

[0039] In one embodiment, a pressing end 52 is provided at one end of the tool holder 23 to facilitate pressing the tool holder 23 downward to cause the limiting platform 51 to be misaligned with one end of the tool holder 23. By providing the pressing end 52, it is convenient to press the pressing end 52 downward to drive one end of the tool holder 23 to compress the spring downward, thereby causing the limiting platform 51 on the pressing member 25 to be misaligned with the end of the tool holder 23. At this time, the pressing member 25 can be moved by pushing or pulling the boss 5 to complete the disassembly.

[0040] In one embodiment, the guide limiting frame 3 includes a guide base frame 31 mounted on the machine base 1 to guide and limit the tool holder 21, and a guide top frame 32 to limit and guide the tool holder 23.

[0041] The guide base 31 guides and limits the position of the tool holder 21 on the machine base 1. The guide top frame 32 guides and limits the position of the tool holder 23. The cooperation of the guide base 31 and the guide top frame 32 guides and limits the position of the die-cutting mechanism 2 on the machine base 1.

[0042] In one embodiment, the device further includes a limiting seat 6 mounted on the base 1, a limiting member 61 movably mounted within the limiting seat 6 and partially protruding from the limiting seat 6, a second spring 62 disposed within the limiting seat 6, and a limiting hole 63 disposed on the cutter holder 21 corresponding to the limiting member 61. With the limiting member 61 and the limiting hole 63, when the die-cutting mechanism 2 is mounted on the base 1, the limiting member 61 engages with the limiting hole 63 to limit the die-cutting mechanism 2 to be mounted on the base 1. With the second spring 62, the limiting member 61 compresses the spring downwards after being compressed, and after releasing the compression, the restoring force of the second spring 62 pushes the limiting member 61 upwards to engage the limiting hole 63.

[0043] In one embodiment, the limiting member 61 is a spherical member or a limiting post with a spherical top. By using a spherical member or a limiting post with a spherical top as the limiting member 61, the tool holder 21 can move along the spherical arc surface of the top when it contacts the top of the limiting member 61 during movement, thus avoiding interference during movement and affecting the installation and disassembly of the tool holder 21.

[0044] In this utility model, when disassembling and assembling the die-cutting mechanism 2:

[0045] During disassembly, by pulling the die-cutting mechanism 2 outward, the die holder 21 exerts downward pressure on the limiting member 61 during the pulling process. After being compressed, the limiting member 61 squeezes the second spring 62 and retracts downward. After the limiting member 61 retracts downward, it disengages from the limiting hole 63. At this time, the die holder 21 moves outward along the guide base 31 until the entire die-cutting mechanism 2 is removed from the base 1.

[0046] When replacing the entire die-cutting mechanism 2, the replacement die-cutting mechanism 2 is moved directly along the guide limit frame 3 on the machine base 1. During the movement, the front end of the die holder 21 contacts the limit member 61 and forms a downward pressing force on it until the limit hole 63 on the die holder 21 corresponds to the position of the limit member 61. Then, the limit member 61 is pushed upward by the reset force of the spring 62 and inserted into the limit hole 63 to complete the fixing of the die-cutting mechanism 2.

[0047] When it is necessary to replace the punch 24 on the die-cutting mechanism 2 or adjust the number and spacing of the punch 24: First, press the pressing end 52 to compress the spring 26 at one end of the die holder 23 downward, causing one end to tilt downward. At this time, the limiting platform 51 on the pressing member 25 is displaced from the end of the die holder 23. Then, by pulling the boss 5 at the other end of the pressing member 25 backward, the pressing member 25 is moved on the die holder 23, so that the disassembly and assembly hole 43 on the pressing member 25 moves to the limiting nut 4. At this time, the pressing member 25 can be removed from the die holder 23. After the pressing member 25 is removed, the punch 24 can be replaced or the punch 24 can be adjusted.

[0048] After the punch 24 is replaced or adjusted, the pressing part 25 is installed on the tool holder 23 after corresponding with the limit nut 4 through the disassembly hole 43. Then, the boss 5 is pushed forward to move the fixing hole 42 on the pressing part 25 to the limit nut 4. At this time, the fixing installation of the pressing part 25 is completed, and the assembly of the die-cutting mechanism 2 is completed. Then, the entire die-cutting mechanism 2 is installed on the machine base 1.

[0049] The scope of protection of this utility model is not limited to the above embodiments and their variations. Conventional modifications and substitutions made by those skilled in the art based on the content of these embodiments are all within the scope of protection of this utility model.
