Description

Technical Field

[0001] This utility model belongs to the field of aluminum silicate cotton board cutting, specifically relating to a cutting fixture for a chromatograph column box insulation board. Background Technology

[0002] The aluminum silicate cotton boards used for insulation inside column boxes are purchased in large blocks, but need to be cut and punched according to the design dimensions to meet usage requirements. The current method involves manual marking with a ruler, manual cutting, and punching, which is inefficient. Furthermore, different sizes of column boxes require different sizes of aluminum silicate cotton blocks, leading to significant errors in manual work and making it unsuitable for large-scale standardized production. Currently, there is no specialized tool for cutting and punching aluminum silicate cotton blocks in one piece. In the field of cutting other types of materials, there are some cutting and punching structures. Patent CN115890801A discloses a blanking-type blister tray punching mold with a square cutting blade and a punch; however, the punch is a solid structure, requiring greater pressure for punching, and easily damaging soft materials; it cannot achieve integral blanking; and it cannot create holes of the required size and shape of aluminum silicate cotton blocks.

The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings and specific embodiments. Figure 1-11As shown, a cutting fixture for a chromatograph column oven insulation plate includes a frame. A die-cutting component 3, which is moved by a linear drive mechanism, is mounted on the frame. The die-cutting component 3 includes a die 32 fixedly connected to the linear drive mechanism. The die 32 includes a mounting plate 320 and a downwardly extending cutting blade 321 fixedly mounted on the mounting plate 320. A material discharge plate 31 is positioned below the mounting plate 320 of the die 32, within the cutting area of ​​the cutting blade 321. A push plate 35 is positioned above the mounting plate 320 of the die 32. The push plate 35 and the material discharge plate 31 are fixedly connected. The die 32 slides up and down in the area between the material discharge plate and the push plate 35. An upper limit part 2, restricting the uppermost position of the push plate 35, is positioned above the push plate 35 on the frame. Here, "upper" and "lower" positions are relative and not fixed. The direction of the reciprocating movement of the die 32 can be considered the up and down direction. The position and shape of the cutting blade 321 are determined as needed. In this invention, the number and position of the cutting blades 321 can be set according to the shape of the material to be cut, such as cotton board. The cutting blades 321 can form a directional cutting area, a triangular cutting area, or other shapes. When the linear drive mechanism drives the die 32 to press down, the die component 3 moves downward as a whole. After the cutting blades 321 contact the material to be cut, they move downward to cut the material. After cutting, the material may be embedded in the cutting area. When the linear drive mechanism drives the die 32 to move upward, the weight of the push plate 35 and the dropping plate 31 is insufficient to push the material out of the cutting area of ​​the die 32. The die component 3 and the material will rise together. When the push plate 35 at the top of the die component 3 contacts the upper limit part 2, the push plate 35 no longer moves upward with the die 32. The distance between the push plate 35 and the die 32 becomes smaller, and the dropping plate 31 moves downward relative to the mounting plate 320 to push the material out of the cutting space of the die 32, thereby realizing automatic material dropping. The shape of the blanking plate 31 can be slightly smaller than the cutting area enclosed by the cutting blade 321, or it can be only a part of the cutting area, as long as it is set within the cutting area to push the cut material away from the die 32. The shape of the push plate 35 can be a single plate or multiple plates, and its shape can be plate-shaped or other; as long as its lower end is fixed to the blanking plate 31, it can push the material in the blanking plate 31 to be discharged with the cooperation of the upper limit part 2. There are various ways to fix the push plate 35 and the blanking plate 31, such as connecting column 36, bolts, etc., and it is necessary to ensure that the space between the two allows the die 32 to move up and down. If the connection position of the push plate 35 and the blanking plate 31 passes through the die 32, a clearance space needs to be provided to avoid interference. The area on the push plate 35 corresponding to the connection position between the linear drive mechanism and the die 32 also needs to be avoided to prevent interference. This utility model can realize the cutting and blanking of the material to be cut.

[0028] At least one downwardly extending punch 322 is also provided on the mounting plate 320; the punch 322 is hollow and has an inner hole; the discharge plate 31 has a clearance hole corresponding to the position of the punch 322; a push rod 38 is fixedly provided on the push plate 35; the lower end of the push rod 38 passes through the mounting plate 320 of the die 32 and slides up and down relative to the inner hole of the punch 322 to push out the waste material inside the punch 322. The shape of the punch 322 can be set according to actual needs, such as circular or other shapes. The punch 322 has an inner hole instead of a structure, so the pressure required for punching is reduced. With the push plate 35 and push rod 38 of this utility model, the waste material can be easily and automatically pushed out from the inner hole to achieve material discharge. Specifically, when the die 32 drives the cutting blade 321 and the punch 322 to move downward to cut the material and punch holes at the same time, the punched waste material enters the inner hole of the punch 322. After punching, the die-cutting component 3 and the material rise together. When the push plate 35 contacts the upper limit part 2, the push plate 35 and the push rod 38 fixedly connected to the push plate 35 remain stationary. The die-cutting mold 32 rises, realizing the relative movement of the push rod 38 and the punch 322. The push rod 38 pushes the waste material in the punch 322 out of the punch 322. When the uppermost push plate 35 of the die-cutting component 3 contacts, the push plate 35 no longer moves upward with the die-cutting mold 32. The distance between the push plate 35 and the die-cutting mold 32 decreases, and the dropping plate 31 moves downward relative to the mounting plate 320, pushing the material out of the cutting space of the die-cutting mold 32, thereby realizing automatic material dropping. The die-cutting mold 32 of this utility model is not only equipped with a cutting blade 321, but also with a punch 322, which can cut the material to be cut, such as cotton board, according to the shape and punch holes according to requirements in one go, improving production efficiency. Meanwhile, the structure of the push plate 35, the discharge plate 31, and the push rod 38 of the die-cutting component 3 allows the cut cotton board to be simultaneously demolded from the die 32 and the waste material to be discharged from the punch 322, resulting in high work efficiency. Of course, the punch 322 can also be solid, as long as its shape corresponds to the hole to be punched. If the punch 322 is solid, a discharge channel needs to be provided below the material corresponding to the position of the punch 322, so that the waste material corresponding to the shape of the punch 322 can be discharged after punching; moreover, the pressure required for punching increases; these are also within the protection scope of this utility model. Handles 33 can also be provided on both sides of the die 32 for convenient manual handling of the die-cutting component 3.

[0029] A detachable connecting rod 37 is provided between the push plate 35 and the blanking plate 31 to achieve a fixed connection between them; the lower end of the connecting rod 37 does not extend beyond the lower surface of the blanking plate 31; the push plate 35 and the push rod 38 are detachably connected; the lowest position of the push rod 38 relative to the punch 322 is either above or level with the lower end of the punch 322; the punch 322 is mounted on the mounting plate 320 and located within the cutting area of ​​the cutting blade 321. Because a die 32 is also provided between the push plate 35 and the blanking plate 31, the two are fixed by a detachable connection, which facilitates manufacturing and installation. The lower end of the connecting rod 37 does not extend beyond the lower surface of the blanking plate 31, thus facilitating the entire blanking plate 31 to push the material cut inside the die 32 to fall. The lowest relative position of the push rod 38 extends beyond or is level with the lower end of the punch 322, facilitating the ejection of waste material inside the punch 322. Of course, other dimensions with slight differences are also acceptable, as long as the waste material can be smoothly discharged. Additionally, it is preferable that the lower end of the push rod 38 located within the punch 322 corresponds to the waste material, and is slightly smaller than the inner hole of the punch 322, to facilitate pushing the waste material. The detachable connection method can be determined as needed, such as common structures like screws, bolts, or pins.

[0030] The connecting rod 37 and the push rod 38 are high-head screws; the large end of the connecting rod 37 is located above the push plate 35, and its lower end is threaded to the blanking plate 31; the large end of the push rod 38 is located in the inner hole of the punch 322, and its upper part is threaded to the push plate 35.

[0031] It also includes a pressure plate 34 fixed to the upper end of the mounting plate 320 of the die 32. The pressure plate 34 is located below the push plate 35, and the linear drive mechanism is fixed to the pressure plate 34. The pressure plate 34 and the mounting plate 320 can be fixed by a detachable connection such as screws. Both the pressure plate 34 and the mounting plate 320 have clearance holes at the corresponding positions of the push rod 38 to allow the push rod 38 to pass through. Setting the pressure plate 34 to bear the pressure of the linear drive mechanism can improve the stress on the die 32 and increase the life of the die 32. Specifically, a drill bit can be fixedly installed at the lower end of the linear drive mechanism; the connecting column 36 is fixedly installed in the middle part of the pressure plate 34; the connecting column 36 passes through the push plate 35 and is fixed to the drill bit.

[0032] The system also includes a worktable 4 mounted on the frame and located below the die-cutting component 3. The worktable 4 includes a platform 41 fixedly mounted on the frame, on which a work plate 42 for placing the material to be cut is mounted. A limiting plate 43 is mounted on the platform 41, and a limiting surface is provided on one end of the limiting plate 43 facing the side of the material to be cut. The platform 41 and the work plate 42 can be a single piece of material, or two pieces of different materials fixed together, facilitating replacement of the work plate 42 if damaged, or replacement with a work plate 42 of a different size. The work plate 42 can be PP board or other materials. Specifically, the platform 41 can be bolted to the limiting plate 43, which extends onto the work plate 42, and the end of the limiting plate 43 on the work plate 42 is L-shaped, used to position the aluminum silicate cotton board to be cut. Preferably, the limiting plate 43 is positioned in two directions to limit the material to be cut from both directions.

[0033] The limiting plate 43 is provided with an elongated hole; the platform 41 and the limiting plate 43 are connected by bolts; thereby enabling the limiting plate 43 to move relative to the platform 41 and adjust its angle. In this utility model, by loosening the bolts, the limiting plate 43 can be moved and rotated to reach a suitable position and angle, thereby limiting cotton boards of different sizes, shapes and specifications.

[0034] The upper limit section 2 includes a limiting mounting member 21 mounted on the frame; a demolding pressure plate 3422 is provided at the lower end of the limiting mounting member 21; several demolding points are provided at the bottom of the demolding pressure plate 3422, and the height of the demolding points is consistent. In practice, the demolding pressure plate 34 can have various styles, and the contact point with the push plate 35 can be a point, a line, or a surface, depending on the specific needs. For example, in the embodiment shown in the attached drawings of this utility model, the limiting mounting member 21 is a rod with a U-shaped groove fixed on the frame, with a demolding pressure plate 3422 provided on each of its two sides. Each demolding pressure plate 34 has two downward-facing demolding points, ensuring that all four positions of the push plate 35 are simultaneously limited.

[0035] The linear drive mechanism is a manual press 1 with its outer casing fixedly mounted on the frame. A drill bit is installed at the lower end of the working end of the manual press 1. An upward-facing connecting column 36 is fixedly mounted on the die 32. The connecting column 36 passes through the push plate 35 and is fixed to the drill bit. The manual press 1 includes a handle; reciprocatingly pulling the handle achieves downward and upward movement of the working end. Of course, the linear drive mechanism can also be other common mechanisms, such as a lead screw and nut mechanism, a press, or a cylinder. In this invention, the overall frame can be the frame integrated with the manual press 1, and the platform 41 is fixedly mounted on the base plate of the manual press 1.

[0036] A return spring 6 is provided between the upper part of the working end of the manual press 1 and the frame above it. In this utility model, a return spring 6 is provided above the working end. After the handle is pulled to cut and punch the material, it is no longer necessary to pull the handle upward to return it. The return spring can drive the working end of the manual press 1 to return to its original position, thereby driving the die component 3 to move as a whole, demold, and eject the waste material.

[0037] In practice: the material to be cut, such as aluminum silicate cotton board A, is placed on the working plate 42. The limiting plate 43 is adjusted so that it abuts against the edge of the cotton board to be cut (such as two vertically set edges). Then, the handle of the manual press 1 is pressed down. At this time, the working end of the manual press 1 drives the die-cutting component 3 to press down. The cutting blade 321 and the punch 322 at the bottom of the die-cutting die 32 perform external cutting and punching on the material to be cut. After completion, the handle of the manual press 1 drives the drill chuck 5 and the die-cutting component 3 to move upward under the action of the return spring 6. After the upper limit part 2 contacts the push plate 35, the material discharge plate 31 and the push rod 38 push out the cut aluminum silicate cotton and waste material.

[0038] The die-cutting component 3 of this utility model not only has a cutting blade 321, but also a punch 322, which can cut the cotton board to be cut according to the shape and punch holes as required in one step, improving production efficiency. The die-cutting component 3 also has a blanking plate 31 and a pusher rod 38, which allows the cut cotton board to be demolded and waste material to be discharged simultaneously, resulting in high operating efficiency. The die-cutting component 3 is connected to the hand press by a drill chuck 5, and different models of die-cutting 32 can be quickly changed according to production needs to meet the needs of different users. The limiting plate 43 of the worktable 4 can be adjusted to accommodate materials of different specifications to be cut.

[0039] The technical features of the embodiments described above can be combined in any way, and as long as there is no contradiction in the combination of these technical features, they should all be considered within the scope of this specification. Without departing from the overall concept of this utility model, any equivalent substitutions or modifications made to the technical solution of this utility model, as well as any changes and improvements, should also be considered within the protection scope of this utility model.
