Description

Technical Field

[0001] This invention relates to the field of EPS mold production technology, and more specifically, to a rapid separation mechanism for cutting aluminum alloy plates for EPS molds. Background Technology

[0002] Currently, the mainstream EPS mold material is mainly made of aluminum alloy plate. Aluminum alloy plate has good thermal conductivity, which can effectively reduce the waste of heat energy. However, in actual application, the processed EPS mold often has 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 aluminum alloy plate, sometimes the cutting blade is easy to get stuck at the cutting position of the aluminum alloy plate, causing the cutting blade to repeatedly cut inside the aluminum alloy plate, resulting in a 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 aluminum alloy sheet is cut, the two cut aluminum alloy sheets will still be briefly pressed together. If the cut aluminum alloy sheets are not separated at this time, it is impossible to determine whether there are any loose threads at the cut position. The current practice is often to continue cutting for a short time to ensure that the aluminum alloy sheet can be completely cut. However, this practice will undoubtedly increase the friction of the cutting blade at the cut position of the aluminum alloy sheet, leading to further damage to the cut position of the aluminum alloy sheet. Summary of the Invention

[0004] To overcome the above-mentioned defects of the prior art, embodiments of the present invention provide a rapid separation mechanism for cutting aluminum alloy plates for EPS molds.

[0005] To achieve the above objectives, this invention provides a rapid separation mechanism for cutting aluminum alloy plates in EPS molds. The mechanism includes a worktable, and its innovation lies in the fact that it also includes a cutting positioning plate and two sets of protective clamps. The surface of the worktable is provided with cutting stations, which are sequentially arranged from top to bottom as a cutting fixing position and a cutting separation position. The cutting positioning plate is elastically positioned on the cutting station, with its initial elastic movement aligned with the cutting fixing position and its final elastic movement aligned with the cutting separation position. Symmetrical separation components are provided on both sides of the cutting positioning plate. Two protective clamps are used to symmetrically clamp the two ends of the aluminum alloy plate. When the aluminum alloy plate is cut at the cutting fixing position, the cutting positioning plate drives the aluminum alloy plate to elastically move from the cutting fixing position to the cutting separation position, causing the two separation components to act on the two protective clamps respectively, instantly separating the cut aluminum alloy plate.

[0006] Furthermore, the aforementioned cutting fixing position is provided with a fixing frame, a cutting groove is provided at the center of the fixing frame, and clearance grooves are provided at the center of both ends of the fixing frame. When the aluminum alloy plate is located inside the fixing frame, the two sets of protective clamps are located inside the clearance grooves and can move up and down respectively.

[0007] Furthermore, the aforementioned protective clamp is U-shaped, with the end face of the aluminum alloy plate clamped inside the opening of the protective clamp. The end face of the protective clamp is provided with a strip plate, and the strip plate is provided with a vertical sliding groove. The interior of the clearance groove is provided with a vertical sliding rail. The vertical sliding groove is slidably set on the vertical sliding rail. When the aluminum alloy plate moves elastically from the cutting fixed position to the cutting separation position, the vertical sliding rail and the vertical sliding groove separate.

[0008] The bottom of the strip plate extends downward with a guide rod, and the separator is provided with a guide groove. The guide rod is set inside the guide groove and can move up and down.

[0009] Furthermore, the aforementioned separating component includes a separating cylinder and a support plate mounted on a worktable. The worktable is provided with a sliding base plate, the sliding direction of which is close to or away from the cutting positioning plate. The output end of the separating cylinder is connected to the base plate. The support plate is elastically mounted on the base plate, the elastic movement direction of which is consistent with the sliding direction of the base plate. A guide groove is provided inside the support plate.

[0010] Furthermore, the base plate is provided with two parallel transverse slide rails, and the bottom of the support plate is provided with two parallel sliders, which are slidably mounted on the transverse slide rails.

[0011] A strip groove is provided between the two transverse slide rails. The strip groove and the transverse slide rails are parallel to each other. Both ends of the strip groove are equipped with buffer springs. A connecting rod extending vertically downward is provided between the two sliders. The connecting rod extends inside the strip groove. Both buffer springs are connected to the two sides of the bottom of the connecting rod.

[0012] Furthermore, the bottom of the connecting rod is provided with a rotatable ball bearing, which is rotatably disposed inside the strip groove.

[0013] Furthermore, the aforementioned cutting station is equipped with four rectangularly distributed support tubes, and the bottom of the cutting positioning plate is equipped with four rectangularly distributed support rods. The support tubes are equipped with pressure springs inside, and the support rods are slidably installed inside the support tubes and connected to the pressure springs.

[0014] The technical effects and advantages of this invention are as follows:

[0015] This invention uses a cutting blade to pre-position aluminum alloy plates for cutting. During this process, the cutting blade acts on the cutting position of the aluminum alloy plate and can pre-cut into the interior of the aluminum alloy plate, ensuring the positioning and cutting of the aluminum alloy plate. At the same time, the cutting action of the cutting blade causes the cutting positioning plate to elastically move the aluminum alloy plate from the cutting fixed position to the cutting separation position. This elastic movement can balance the cutting force of the cutting blade inside the aluminum alloy plate, preventing the cutting blade from getting stuck inside the aluminum alloy plate and reducing deformation at the cutting position of the aluminum alloy plate, thereby effectively protecting the internal structure of the aluminum alloy plate.

[0016] This invention uses two separating components that act on the protective clamp. At the instant the aluminum alloy plate is cut, the two separating components instantly separate the cut aluminum alloy plate. This not only reduces the friction between the cutting blade and the inside of the aluminum alloy plate, but also achieves automatic separation of the cut aluminum alloy plate.

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] like Figures 1 to 3In one specific embodiment of the present invention, the structure includes a workbench 1, a cutting positioning plate 11, and two sets of protective clamps 12. The surface of the workbench 1 is provided with a cutting station 13, which is arranged from top to bottom as a cutting fixing position 14 and a cutting separation position 15. The cutting positioning plate 11 is elastically mounted on the cutting station 13. The initial position of the elastic movement of the cutting positioning plate 11 is flush with the cutting fixing position 14, and the final position of the elastic movement of the cutting positioning plate 11 is flush with the cutting separation position 15. Symmetrical separation members 2 are provided on both sides of the cutting positioning plate 11. The two protective clamps 12 are used to symmetrically clamp the two ends of the aluminum alloy plate. When the aluminum alloy plate is cut at the cutting fixing position 14, the cutting positioning plate 11 drives the aluminum alloy plate to move elastically from the cutting fixing position 14 to the cutting separation position 15, so that the two separation members 2 act on the two protective clamps 12 respectively, and the cut aluminum alloy plate is separated instantly.

[0022] In this invention, the aluminum alloy plate cutting process is as follows: Two sets of protective clamps 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. The aluminum alloy plate is positioned at the cutting fixing position 14. At this time, the aluminum alloy plate is fixed at the cutting fixing position 14, which facilitates the cutting blade to accurately cut the cutting position on the aluminum alloy plate. The cutting of the aluminum alloy plate by the external cutting blade is specifically divided into two steps:

[0023] The cutting blade performs pre-positioned cutting on the aluminum alloy plate: During this process, the cutting blade acts on the cutting position of the aluminum alloy plate. The cutting blade can pre-cut into the interior of the aluminum alloy plate, ensuring the positioning and cutting of the aluminum alloy plate. At the same time, the cutting action of the cutting blade causes the cutting positioning plate 11 to move the aluminum alloy plate elastically from the cutting fixed position 14 to the cutting separation position 15. This elastic movement can balance the cutting force of the cutting blade inside the aluminum alloy plate, prevent the cutting blade from getting stuck inside the aluminum alloy plate, reduce the deformation of the aluminum alloy plate at the cutting position, and thus effectively protect the internal structure of the aluminum alloy plate.

[0024] The cutting blade performs a complete cut on the aluminum alloy plate: During this process, the cutting positioning plate 11 moves to the cutting separation position 15, and the cutting blade gradually completes the cutting of the aluminum alloy at the cutting position.

[0025] When the aluminum alloy plate is cut, the two separating parts 2 act on the protective clamp 12 respectively. At the instant the aluminum alloy plate is cut, the two separating parts 2 instantly separate the cut aluminum alloy plate. This not only reduces the friction between the cutting blade and the inside of the aluminum alloy plate, but also realizes the automatic separation of the cut aluminum alloy plate.

[0026] In this invention, as a preferred embodiment, the above-mentioned cutting fixing position 14 is provided with a fixing frame 3, the center position of the fixing frame 3 is provided with a cutting groove 31, and the center positions of both ends of the fixing frame 3 are provided with clearance grooves 32. When the aluminum alloy plate is located inside the fixing frame 3, the two sets of protective clips 12 are respectively located inside the clearance grooves 32 and can move up and down.

[0027] In this 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 placed inside the relief groove 32. The relief groove 32 plays a limiting role for the protective clip 12. At the same time, the entire aluminum alloy frame is restricted inside the fixing frame 3, thereby ensuring that the aluminum alloy plate is positioned and fixed at the cutting fixing position 14. The protective clip 12 moves up and down inside the relief groove 32. On the one hand, it can place the aluminum alloy plate 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.

[0028] In this invention, as a preferred embodiment, the protective clip 12 is U-shaped, and the end face of the aluminum alloy plate is clamped inside the opening of the protective clip 12. The end face of the protective clip 12 is provided with a strip plate 33, and the strip plate 33 is provided with a vertical sliding groove 34. The interior of the clearance groove 32 is provided with a vertical sliding rail 35. The vertical sliding groove 34 is slidably arranged on the vertical sliding rail 35. When the aluminum alloy plate moves elastically from the cutting fixed position 14 to the cutting separation position 15, the vertical sliding rail 35 and the vertical sliding groove 34 separate.

[0029] 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 inside the guide groove 37.

[0030] In this invention, the end of the aluminum alloy plate is fixed inside the opening of the protective clip 12. The process of setting the protective clip 12 inside the clearance groove 32 is as follows: First, the guide rod 36 is aligned with the guide groove 37 so that the guide rod 36 is guided into the interior of the guide groove 37. Then, the vertical slide 34 is slid into the interior of the vertical slide rail 35 until the aluminum alloy plate is placed on the cutting positioning plate 11. When the aluminum alloy plate moves elastically from the cutting fixing position 14 to the cutting separation position 15, the vertical slide rail 35 and the vertical slide rail 35 separate, that is, the aluminum alloy plate leaves the fixing frame 3.

[0031] In this invention, as a preferred embodiment, the separation component 2 includes a separation cylinder 21 and a support plate 22 disposed on the worktable 1. The worktable 1 is provided with a slidable base plate 4. The sliding direction of the base 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 base plate 4. The support plate 22 is elastically and movably disposed on the base plate 4. The elastic movement direction of the support plate 22 is consistent with the sliding direction of the base plate 4. The guide groove 37 is disposed inside the support plate 22.

[0032] In this invention, when the guide rod 36 is inserted into the guide groove 37, the position of the support plate 22 can be adjusted to facilitate the insertion of the guide rod 36 into the guide groove 37.

[0033] In this invention, after the aluminum alloy plate is cut at the cutting position, the separation cylinder 21 is opened. The separation cylinder 21 first moves the base plate 4 away from the cutting positioning plate 11. Depending on the cutting situation of the aluminum alloy plate, the movement of the bearing plate 22 is specifically divided into the following two situations:

[0034] When the cutting position of the aluminum alloy plate is completely cut off by the cutting blade, the base plate 4 drives the bearing plate 22 to move synchronously, instantly breaking the disconnected aluminum alloy plate and completing the separation of the aluminum alloy plate.

[0035] When there are still some tangled threads at the cut position of the aluminum alloy plate, the cut position is still in a semi-connected state. This semi-connected state restricts the movement of the two support plates 22 with the base plate 4, thereby preventing the cut position of the aluminum alloy plate from being forcibly pulled off and damaged. At this time, the two support plates 22 hold the two ends of the aluminum alloy plate in an elastic outward pulling state. The cutting blade needs to continue cutting the cut position of the aluminum alloy plate. When the tangled threads break, the two support plates 22 will instantly pull the broken aluminum alloy plate apart under the action of elasticity, completing the separation of the aluminum alloy plate.

[0036] In this invention, as a preferred embodiment, the base plate 4 is provided with two parallel transverse slide rails 41, and the bottom of the bearing plate 22 is provided with two parallel sliders 42, which are slidably disposed on the transverse slide rails 41.

[0037] A strip groove 43 is provided between the two transverse slide rails 41. The strip groove 43 and the transverse slide rails 41 are parallel to each other. Both ends of the strip groove 43 are provided with buffer springs 44. A vertically downward extending connecting rod 45 is provided between the two sliders 42. The connecting rod 45 extends inside the strip groove 43. Both buffer springs 44 are connected to the two sides of the bottom of the connecting rod 45.

[0038] In this invention, the slider 42 slides on the transverse slide rail 41, ensuring the stability of the support plate 22's movement on the base plate 4. At the same time, the connecting rod 45 moves elastically inside the strip groove 43 through two buffer springs 44, realizing the elastic movement of the support plate 22 on the base plate 4.

[0039] In this invention, as a preferred embodiment, the bottom of the connecting rod 45 is provided with a rotatable ball bearing 46, which is rotatably disposed inside the strip groove 43.

[0040] In this invention, the ball bearing 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.

[0041] In this invention, as a preferred embodiment, the cutting station 13 is provided with four rectangularly distributed support tubes 5, and the bottom of the cutting positioning plate 11 is provided with four rectangularly distributed support rods 51. The support tubes 5 are provided with pressure springs 52 inside, and the support rods 51 are slidably arranged inside the support tubes 5 and connected to the pressure springs 52.

[0042] In this invention, the support rod 51 moves up and down elastically inside the support tube 5 via the pressure spring 52, thereby realizing the up and down elastic movement of the cutting positioning plate 11.

[0055] Example 2: Special Analysis of EPS Mold Cutting Scenarios

[0056] Material properties:

[0057] The aluminum alloy plate for EPS molds needs to meet the requirements of high thermal conductivity and lightweight, but its thin-walled structure (thickness ≤ 5mm) is prone to internal micro-cracks due to stress concentration during cutting.

[0058] Technical requirements:

[0059] Precise positioning: The fixed frame 3 and the clearance groove 32 cooperate to ensure that the cutting deviation is ≤0.1mm (0.5mm for the control group).

[0060] Instant separation: The separation mechanism between the vertical slide rail 35 and the slide groove 34 avoids microcracks caused by residual pulling during cutting (microcrack rate in the experimental group <0.5%, and in the control group it is 5%).

[0061] Industry comparison:

[0062] The general-purpose aluminum alloy cutting device is not optimized for the thin-walled characteristics of EPS molds. Its horizontal material transfer is prone to causing misalignment of the sheet metal, which cannot meet the precision and structural integrity requirements of EPS molds.
