Description

Technical Field

[0001] The invention relates to the technical field of production of EPS moulds, and more specifically to a quick separation mechanism for cutting aluminium alloy plates of EPS moulds. Background Art

[0002] At present, the mainstream EPS mold materials in the market are mainly made of aluminum alloy plates. Aluminum alloy plates have good thermal conductivity and can effectively reduce the waste of heat energy. However, in actual application, the processed EPS molds often have heat energy leakage at the connection position of the aluminum alloy plate, resulting in heat energy waste. The reason is that during the cutting process of the aluminum alloy plate, the cutting knife is sometimes easily stuck in the cutting position of the aluminum alloy plate, causing the cutting knife to repeatedly cut inside the aluminum alloy plate, resulting in certain deformation at the cutting position of the aluminum alloy plate, which can easily damage the internal structure of the aluminum alloy plate.

[0003] Secondly, after each cutting of the aluminum alloy plates is completed, the two cut aluminum alloy plates will still be briefly pressed together. At this time, if the cut aluminum alloy plates are not separated, it is impossible to determine whether there is any lingering connection at the cutting position of the aluminum alloy plates. The existing practice is often to continue cutting with the cutting knife for a short period of time to ensure that the aluminum alloy plates can be completely cut. However, this practice will undoubtedly increase the friction of the cutting knife at the cutting position of the aluminum alloy plates, resulting in further damage to the cutting position of the aluminum alloy plates. Summary of the invention

[0006] Furthermore, the above-mentioned cutting and fixing position is provided with a fixing frame, a cutting groove is provided at the center position of the fixing frame, and avoidance grooves are provided at the center positions of both ends of the fixing frame.

This not only reduces the friction of the cutting knife on the inside of the aluminum alloy plate, but also realizes the automatic separation of the cut aluminum alloy plate.

[0017] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0018] like Figures 1 to 3It is a specific embodiment of the present invention, and its structure includes a workbench 1, and its structure also includes a cutting positioning plate 11 and two groups of protective clamps 12. A cutting station 13 is provided on the surface of the workbench 1. The cutting station 13 is sequentially arranged as a cutting fixed position 14 and a cutting separation position 15 from top to bottom. The cutting positioning plate 11 is arranged on the cutting station 13 so as to be elastically movable up and down. The initial position of the elastic movement of the cutting positioning plate 11 is flush with the cutting fixed position 14, and the terminal position of the elastic movement of the cutting positioning plate 11 is flush with the cutting separation position 15. Symmetrical separating pieces 2 are provided on both sides of the cutting positioning plate 11. The two protective clamps 12 are used to symmetrically clamp at both ends of the aluminum alloy plate. When the aluminum alloy plate is cut at the cutting fixed position 14, the cutting positioning plate 11 drives the aluminum alloy plate to elastically move from the cutting fixed position 14 to the cutting separation position 15, so that the two separating pieces 2 act on the two protective clamps 12 respectively to instantly separate the aluminum alloy plate after cutting.

[0019] In the present invention, the process of cutting the aluminum alloy plate is as follows: two sets of protective clips 12 are symmetrically clamped at both ends of the aluminum alloy plate, and then the aluminum alloy plate is placed on the cutting positioning plate 11, and the aluminum alloy plate is positioned on the cutting fixed position 14. At this time, the position of the aluminum alloy plate at the cutting fixed position 14 is in a fixed state, so that it is convenient for the cutting knife to accurately cut the cutting position on the aluminum alloy plate. The cutting of the aluminum alloy plate by the external cutting knife is specifically divided into two steps: The cutting knife performs pre-positioning cutting on the aluminum alloy plate: during this process, the cutting knife acts on the cutting position of the aluminum alloy plate, and the cutting knife can pre-cut into the interior of the aluminum alloy plate, ensuring the positioning cutting of the aluminum alloy plate by the cutting knife. At the same time, the cutting action of the cutting knife enables the cutting positioning plate 11 to drive the aluminum alloy plate to elastically move from the cutting fixed position 14 to the cutting separation position 15. This elastic movement can balance the chip force of the cutting knife inside the aluminum alloy plate, avoid the cutting knife from being stuck inside the aluminum alloy plate, and reduce the deformation of the aluminum alloy plate at the cutting position, thereby effectively protecting the internal structure of the aluminum alloy plate.

[0020] The cutting knife completely cuts the aluminum alloy plate: during this process, the cutting positioning plate 11 moves to the cutting separation position 15, and the cutting knife gradually completes the cutting of the aluminum alloy cutting position.

[0021] When the aluminum alloy plate is cut, the two separating pieces 2 act on the protective clamp 12 respectively. At the moment the aluminum alloy plate is cut, the two separating pieces 2 instantly separate the cut aluminum alloy plate. This not only reduces the friction of the cutting knife on the inside of the aluminum alloy plate, but also realizes the automatic separation of the cut aluminum alloy plate.

[0022] In the present invention, as a preferred solution, the above-mentioned cutting and fixing position 14 is provided with a fixed frame 3, a cutting groove 31 is provided at the center position of the fixed frame 3, and avoidance grooves 32 are provided at the center positions of both ends of the fixed frame 3. When the aluminum alloy plate is located inside the fixed frame 3, the two sets of protective clips 12 can move up and down and are located inside the avoidance grooves 32 respectively.

[0023] In the present invention, the principle of fixing the aluminum alloy plate at the cutting fixing position 14 is as follows: after the protective clip 12 is clamped at both ends of the aluminum alloy plate, the protective clip 12 is set inside the avoidance groove 32, and the avoidance groove 32 serves to limit the protective clip 12. At the same time, the entire aluminum alloy frame is restricted inside the fixed frame 3, thereby ensuring that the aluminum alloy plate is positioned and fixed at the cutting fixing position 14, and the protective clip 12 moves up and down inside the avoidance groove 32. On the one hand, the aluminum alloy plate can be placed downward on the cutting positioning plate 11, and on the other hand, it can ensure that the aluminum alloy plate can move downward from the cutting fixing position 14.

[0024] In the present invention, as a preferred solution, the above-mentioned protection clamp 12 is U-shaped, the end face of the aluminum alloy plate is clamped inside the opening of the protection clamp 12, the end face of the protection clamp 12 is provided with a strip plate 33, the strip plate 33 is provided with a vertical slide groove 34, the inside of the avoidance groove 32 is provided with a vertical slide rail 35, the vertical slide groove 34 is slidably arranged on the vertical slide rail 35, when the aluminum alloy plate elastically moves from the cutting fixed position 14 to the cutting separation position 15, the vertical slide rail 35 and the vertical slide groove 34 are separated; A guide rod 36 extends downward from the bottom of the strip plate 33 , and a guide groove 37 is provided on the separator 2 . The guide rod 36 is movably disposed in the guide groove 37 .

[0025] In the present invention, the end of the aluminum alloy plate is fixed inside the opening of the protective clip 12, and the setting process of the protective clip 12 inside the avoidance groove 32 is as follows: first align the guide rod 36 with the guide groove 37 so that the guide rod 36 is introduced into the inside of the guide groove 37, and then the vertical slide groove 34 is slid into the inside of the vertical slide rail 35 until the aluminum alloy plate is placed on the cutting positioning plate 11. When the aluminum alloy plate elastically moves from the cutting fixing position 14 to the cutting separation position 15, the vertical slide rail 35 and the vertical slide rail 35 are separated, that is, the aluminum alloy plate leaves the fixed frame 3.

[0026] In the present invention, as a preferred embodiment, the above-mentioned separation component 2 includes a separation cylinder 21 and a supporting plate 22 arranged on the workbench 1. A slidable bottom plate 4 is provided on the workbench 1, and the sliding direction of the bottom plate 4 is close to or away from the cutting positioning plate 11. The output end of the separation cylinder 21 is connected to the bottom plate 4, and the supporting plate 22 is elastically and movably arranged on the bottom plate 4. The elastic activity direction of the supporting plate 22 is consistent with the sliding direction of the bottom plate 4, and the guide groove 37 is arranged inside the supporting plate 22.

[0027] In the present invention, when the guide rod 36 is inserted into the guide groove 37 , the position of the bearing plate 22 can be adjusted to facilitate the insertion of the guide rod 36 into the guide groove 37 .

[0028] In the present invention, when the cutting position of the aluminum alloy plate is cut, the separation cylinder 21 is turned on, and the separation cylinder 21 first drives the bottom plate 4 away from the cutting positioning plate 11. According to the cutting condition of the aluminum alloy plate, the movement condition of the carrier plate 22 is specifically divided into the following two conditions: When the cutting position of the aluminum alloy plate is completely cut off by the cutting knife, the bottom plate 4 drives the carrying plate 22 to move synchronously, and the broken aluminum alloy plate is instantly cut off, thereby completing the separation of the aluminum alloy plate.

[0029] When there is still a connected position at the cutting position of the aluminum alloy plate, the cutting position of the aluminum alloy plate is still in a semi-connected state. This semi-connected state restricts the two supporting plates 22 from moving with the bottom plate 4, thereby avoiding forcibly pulling off the cutting position of the aluminum alloy plate and damaging the cutting position of the aluminum alloy plate. At this time, the two supporting plates 22 put the two ends of the aluminum alloy plate in a state of elastic outward pulling, and the cutting knife needs to continue cutting the cutting position of the aluminum alloy plate. When the connected position is disconnected, the two supporting plates 22 will instantly pull the disconnected aluminum alloy plates apart under the action of elasticity to complete the separation of the aluminum alloy plates.

[0030] In the present invention, as a preferred solution, the bottom plate 4 is provided with two mutually parallel transverse slide rails 41, and the bottom of the carrying plate 22 is provided with two mutually parallel sliders 42, and the sliders 42 are slidably arranged on the transverse slide rails 41; A strip groove 43 is provided between the two transverse slide rails 41. The strip groove 43 and the transverse slide rail 41 are parallel to each other. Buffer springs 44 are provided at both ends of the strip groove 43. A connecting rod 45 extending vertically downward is provided between the two sliders 42. The connecting rod 45 extends inside the strip groove 43. Two buffer springs 44 are connected to both sides of the bottom of the connecting rod 45.

[0031] In the present invention, the slider 42 slides on the transverse slide rail 41 to ensure the stability of the movement of the supporting plate 22 on the base plate 4. At the same time, the connecting rod 45 elastically moves inside the strip groove 43 through two buffer springs 44 to realize the elastic movement of the supporting plate 22 on the base plate 4.

[0032] In the present invention, as a preferred solution, a rotatable ball 46 is provided at the bottom of the connecting rod 45 , and the ball 46 is rotatably arranged inside the strip groove 43 .

[0033] In the present invention, the ball 46 rotates inside the strip groove 43 to ensure the stability of the elastic movement of the connecting rod 45 inside the strip groove 43 .

[0034] In the present invention, as a preferred solution, the above-mentioned cutting station 13 is provided with four support tubes 5 distributed in a rectangular shape, and the bottom of the cutting positioning plate 11 is provided with four support rods 51 distributed in a rectangular shape. The interior of the support tube 5 is provided with a pressure spring 52, and the support rod 51 is slidable up and down inside the support tube 5 and is connected to the pressure spring 52.

[0035] In the present invention, the support rod 51 performs elastic movement up and down inside the support tube 5 through the pressure spring 52 , thereby realizing the elastic movement of the cutting positioning plate 11 up and down.

[0036] Example 1: Cutting knife risk comparison test Test purpose: To verify the improvement effect of the quick separation mechanism of this application on the risk of cutting knife jam.

[0037] Test subjects: Experimental group: using the quick separation mechanism of the present application (including elastic motion cutting positioning plate, U-shaped protection clip and vertical slide rail design).

[0038] Control group: cutting device with traditional rigid pusher structure.

[0039] Test conditions: Material: EPS mold special aluminum alloy plate (model AL-6061-T6, thickness 3mm).

[0040] Cutting parameters: cutting blade speed 3000rpm, feed speed 0.5m / min, cutting depth 2.8mm.

[0041] Test times: Repeat cutting 100 times for each group, and count the number of knife jams and the deformation rate of the cutting surface.

[0042] Test results: in conclusion: This application significantly reduces the risk of knife jamming (improvement rate 90%) through elastic movement and linkage separation design, while reducing cutting surface deformation and improving separation efficiency by 75%, verifying the creativity of the technical solution.

[0043] Example 2: Analysis of the particularity of EPS mold cutting scenarios Material properties: EPS mold aluminum alloy plates need to meet the requirements of high thermal conductivity and lightweight, but their thin-walled structure (thickness ≤ 5mm) is prone to internal microcracks due to stress concentration during cutting.

[0044] Technical requirements: Precise positioning: The fixed frame 3 cooperates with the avoidance groove 32 to ensure that the cutting deviation is ≤0.1mm (0.5mm for the control group).

[0045] Instant separation: The separation mechanism of the vertical slide rail 35 and the slide groove 34 avoids micro cracks caused by pulling of cutting residues (the micro crack rate of the experimental group is less than 0.5%, and that of the control group is 5%).

[0046] Industry comparison: The general aluminum alloy cutting device is not optimized for the thin-wall characteristics of EPS molds. Its horizontal material shifting can easily cause plate misalignment and cannot meet the accuracy and structural integrity requirements of EPS molds.
