Description

Technical Field

[0001] This utility model belongs to the field of graphite packing cutting technology, and is particularly related to a graphite packing cutting and fixing device. Background Technology

[0002] Graphite packing, in long strips, is a high-performance sealing material primarily used for dynamic seals in high-temperature, high-pressure, and corrosive environments. During use, the long graphite packing needs to be cut to the required size to match the sealing location on the equipment. Because graphite packing is relatively soft, and it needs to be cut at a 45-degree angle, manual cutting can lead to slow cutting speeds due to packing movement. This can result in deformed, scattered, and uneven cut surfaces, affecting the sealing effect and even causing leakage that could damage the equipment. Therefore, improvements are necessary. Utility Model Content

[0003] To address the aforementioned deficiencies in the prior art, this application provides a graphite packing cutting and fixing device that can fix the graphite packing and then cut it from the first notch and the second notch, thus preventing the graphite packing from shaking during the cutting process.

[0004] To achieve the above objectives, the present invention employs the following technology:

[0005] A graphite packing cutting and fixing device includes:

[0006] A rectangular support platform has a fixed clamp plate on its upper part along its length. The fixed clamp plate has a first notch that runs through both sides of it at an angle of 45 degrees.

[0007] A movable clamping plate is slidably mounted on the top of the rectangular support platform along the width direction of the rectangular support platform, and the movable clamping plate is parallel to the fixed clamping plate. The fixed clamping plate has a second notch that runs through both sides at an angle, and the second notch is parallel to the first notch. The top of the rectangular support platform has multiple fixing holes. Two sets of fixing nails that match the size of the fixing holes are vertically inserted through the movable clamping plate. The two sets of fixing nails are located on both sides of the second notch. When the movable clamping plate moves to a first preset distance from the fixed clamping plate, the two sets of fixing nails are aligned with the multiple fixing holes, and the second notch is located in the direction of extension of the first notch toward the movable clamping plate.

[0008] Furthermore, the top of the rectangular support platform has multiple T-shaped grooves along its width direction, and the bottom of the movable clamping plate has two sets of T-shaped sliders. The two sets of T-shaped sliders are slidably connected in the multiple T-shaped grooves, and the two sets of T-shaped sliders are respectively located on both sides of the second notch.

[0009] Furthermore, the top of the movable clamping plate has multiple through holes extending through the bottom of the T-shaped slider, and multiple fixing pins are respectively inserted into the multiple through holes, and multiple fixing holes are respectively opened below the multiple T-shaped sliding grooves.

[0010] Furthermore, when the T-shaped slider slides toward the fixed clamping plate until it abuts the end of the T-shaped groove, the multiple through holes are aligned with the multiple fixed holes respectively.

[0011] Furthermore, the fixing hole penetrates the bottom of the rectangular support platform, and the bottom of the rectangular support platform is connected to a lifting mechanism. A push plate is provided below the rectangular support platform, and multiple push columns are vertically provided above the push plate. The multiple push columns are aligned with multiple fixing holes, and the length of the push columns matches the length of the fixing holes. When the lifting mechanism drives the rectangular support platform to descend to abut the push plate, the push columns completely enter the fixing holes.

[0012] Furthermore, two pairs of vertical guide columns are installed on the rectangular support platform. The push plate is fixedly connected to the two pairs of guide columns. The push plate has a receiving hole. The telescopic end of the lifting mechanism passes through the receiving hole and is connected to the bottom of the rectangular support platform. The lifting mechanism is fixed on a base plate. The bottom of both pairs of guide columns is connected to the top of the base plate.

[0013] The beneficial effects of this utility model are as follows:

[0014] 1. The device can fix the graphite packing and then cut the graphite packing along the length direction of the first notch and the second notch. It can stably cut the graphite packing into two segments and avoid the graphite packing shaking during the cutting process, and form a 45-degree inclined cutting surface.

[0015] 2. When the lifting mechanism lowers the rectangular support platform to the push plate, the push column fully enters the fixing hole, which can simultaneously push the fixing nails in multiple fixing holes upwards to disengage from the fixing holes. This facilitates the quick release of the movable clamping plate from the graphite packing after the graphite packing is cut. Attached Figure Description

Detailed Implementation

[0022] To make the objectives, technical solutions and advantages of the present utility model clearer, the implementation methods of the present utility model will be described in detail below with reference to the accompanying drawings. However, the embodiments described in the present utility model are only some embodiments of the present utility model, and not all embodiments.

[0023] This application provides a graphite packing cutting and fixing device, such as... Figures 1-5 As shown, it includes a rectangular support platform 1, a fixed clamping plate 2, and a movable clamping plate 3.

[0024] Specifically, the fixed clamp 2 is positioned above the rectangular support platform 1 along its length. The fixed clamp 2 has a first notch 201 extending through both sides at an angle of 45 degrees to the fixed clamp 2. The movable clamp 3 slides along the width of the rectangular support platform 1 on top of the platform, parallel to the fixed clamp 2. The fixed clamp 2 has a second notch 301 extending through both sides at an angle, parallel to the first notch 201. Multiple fixing holes 101 are provided on the top of the rectangular support platform 1, and the movable clamp 3 is vertically inserted through... Two sets of fixing pins 4, matching the size of the fixing holes 101, are provided. The two sets of fixing pins 4 are located on either side of the second notch 301. When the movable clamping plate 3 moves to a first preset distance from the fixed clamping plate 2, the two sets of fixing pins 4 align with multiple fixing holes 101, and the second notch 301 is positioned in the extension direction of the first notch 201 towards the movable clamping plate 3. This allows the cutting edge for cutting the graphite packing to move from inside the first notch 201 along a straight line to inside the second notch 301. After the graphite packing clamped between the movable clamping plate 3 and the fixed clamping plate 2 is cut, a 45-degree cut surface is formed at the cut. Specifically, the first preset distance is less than the width of the graphite packing in its natural state.

[0025] In actual use, first push the movable clamp 3 away from the fixed clamp 2, place the graphite packing to be cut between the movable clamp 3 and the fixed clamp 2, and pull the graphite packing to the required cutting length. Then push the movable clamp 3 towards the fixed clamp 2 to clamp the graphite packing, and align the fixing pin 4 on the movable clamp 3 with the fixing hole 101. Then, insert the fixing pin 4 into the fixing hole 101 to fix the movable clamp 3. Next, use a blade to cut the graphite packing along the length of the first notch 201 and the second interface to cut the graphite packing, and make the cut surface form a 45-degree cut surface to avoid the graphite packing shaking during cutting, which would cause the graphite packing to deform, disperse, and have an uneven cut surface.

[0026] For details, please refer to Figure 2 , Figure 3 The top of the rectangular support platform 1 has multiple T-shaped grooves 102 along its width. The bottom of the movable clamping plate 3 has two sets of T-shaped sliders 5, which are slidably connected within the T-shaped grooves 102. The two sets of T-shaped sliders 5 are respectively located on both sides of the second notch 301, allowing the movable clamping plate 3 to move only along the width of the rectangular support platform 1. More specifically, the top of the movable clamping plate 3 has multiple through holes 302 penetrating the bottom of the T-shaped sliders 5. Multiple fixing pins 4 are respectively inserted into the through holes 302, and multiple fixing holes 101 are respectively located below the T-shaped grooves 102. When the T-shaped sliders 5 slide towards the fixed clamping plate 2 and abut against the end of the T-shaped grooves 102, the multiple through holes 302 align with the multiple fixing holes 101. This design allows the movable clamping plate 3 to be pushed towards the fixed clamping plate 2 until the T-shaped sliders 5 abut against the end of the T-shaped grooves 102 when clamping the graphite packing, achieving rapid alignment of the fixing pins 4 and the fixing holes 101.

[0027] Preferred options, please refer to Figure 4 , Figure 5 A fixing hole 101 penetrates the bottom of a rectangular support platform 1. The bottom of the rectangular support platform 1 is connected to a lifting mechanism 6. A push plate 7 is located below the rectangular support platform 1, and multiple pushing columns 701 are vertically arranged above the push plate 7. The multiple pushing columns 701 are respectively aligned with multiple fixing holes 101, and the length of the pushing column 701 matches the length of the fixing hole 101. Specifically, the fixing nail 4 can be selected as a pin. When the lifting mechanism 6 drives the rectangular support platform 1 to descend to abut the push plate 7, the pushing column 701 is fully inserted into the fixing hole 101, which can simultaneously push the fixing nail 4 in the multiple fixing holes 101 upwards until it is disengaged from the fixing hole 101. This facilitates the quick release of the clamping of the movable clamping plate 3 on the graphite packing after the graphite packing is cut.

[0028] For details, please refer to Figure 4 , Figure 5Two pairs of vertical guide columns 8 are installed on the rectangular support platform 1. A push plate 7 is fixedly connected to the two pairs of guide columns 8. The push plate 7 has a receiving hole. The telescopic end of the lifting mechanism 6 passes through the receiving hole and connects to the bottom of the rectangular support platform 1. The lifting mechanism 6 is fixed to a base plate 9. The bottoms of the two pairs of guide columns 8 are connected to the top of the base plate 9. When the lifting mechanism 6 moves the rectangular support platform 1 up and down, the rectangular support platform 1 can only move along the guide columns 8, which can improve the stability of the vertical movement of the rectangular support platform 1.
