Description

A heat insulation strip processing equidistant cutting equipment Technical Field

[0001] This utility model relates to the field of cutting device technology, specifically a heat insulation strip processing equidistant cutting device. Background Technology

[0002] Thermal break strips are functional components installed in thermally broken aluminum alloy doors and windows. Their core function is to block the heat conduction path between aluminum profiles through low thermal conductivity materials, thereby significantly improving the thermal insulation performance of doors and windows. During production and processing, they need to be cut according to the size of the window.

[0003] An investigation revealed that a Chinese utility model patent (Publication No.: CN221364952U) discloses an adjustable heat insulation strip processing equidistant cutting device, comprising a base plate with multiple cutting grooves on its top; multiple hydraulic cylinders, all fixedly mounted on the top of the base plate, with a common top plate fixedly mounted on the output rods of the cylinders; a fan fixedly mounted on the base plate; a diversion pipe fixedly mounted on the exhaust end of the fan, with multiple air blowing pipes provided on the diversion pipe; and a fixing mechanism disposed on the base plate for fixing the heat insulation strip. The adjustable heat insulation strip processing equidistant cutting device provided by this utility model has the advantages of convenient and quick adjustment of the cutting spacing, good working efficiency, time and labor saving, and good performance.

[0004] Although the aforementioned patent can achieve adjustable equidistant cutting, the length of the heat insulation strip is much greater than its width. This means that even when the two ends of the heat insulation strip are clamped and positioned, the large span makes the contact surface between the cutter and the heat insulation strip prone to vibration. Especially when the cutter is not sharp, this can easily cause the heat insulation strip to shift, thereby reducing the cutting accuracy of the heat insulation strip.

[0005] Therefore, this utility model provides an equidistant cutting device for processing heat insulation strips to solve the above problems. Summary of the Invention

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] As shown in Figures 1-6, this utility model provides an equidistant cutting device for processing heat insulation strips, including a support assembly 1. The support assembly 1 includes a worktable 11, with a hydraulic cylinder 2 fixedly connected to the corner of the upper surface of the worktable 11. The hydraulic cylinder 2 is fixedly connected to a top plate 3 for lifting. A drive assembly 4 and a cutting tool 5 are also included. The drive assembly 4 is located below the top plate 3 and is used for adjusting and rotating the cutting tool 5. The drive assembly 4 includes bearing seats 41, with a bidirectional lead screw 42 and a transmission shaft 43 rotatably connected between the bearing seats 41. Two nut pairs 45 are symmetrically distributed on the outer wall of the bidirectional lead screw 42. Three transmission sleeves 47 are connected to the outer wall of the transmission shaft 43. The two transmission sleeves 47 are connected to the nut pairs 45 via guide frames 46. A servo motor 44 is fixedly connected to one end of both the 42 and the drive shaft 43. The rotation of the bidirectional lead screw 42 and the drive shaft 43 is achieved through the drive component 4. When the bidirectional lead screw 42 rotates, it can drive the two-sided cutter 5 to move synchronously, thereby achieving fixed-length cutting. When the drive shaft 43 rotates, it can drive the cutter 5 to rotate at high speed through the transmission sleeve 47. In conjunction with the hydraulic cylinder 2, it drives the top plate 3 to descend, thereby achieving synchronous descent of the drive component 4 and the cutter 5, which can cut the heat insulation strip above the worktable 11. When the servo motor 44 starts and drives the bidirectional lead screw 42 to rotate, it can drive the nut pair 45 to move synchronously. At the same time, through the connection of the guide frame 46, it drives the transmission sleeve 47 to move horizontally, thereby driving the cutter 5 to adjust the spacing.

[0032] The clamping assembly 6 is symmetrically distributed on both sides of each cutter 5 and is used to assist in clamping the heat insulation strip. The clamping assembly 6 includes a support plate 61, a positioning sleeve 62 is fixedly connected to the upper surface of the support plate 61, and guide rods 63 are provided at both ends of the support plate 61. The guide rods 63 are slidably connected to the bottom of the top plate 3. A guide shaft 64 passes through the inside of the support plate 61, and a pressure plate 65 is fixedly connected to the bottom of the guide shaft 64. A spring 66 is sleeved on the outside of the guide shaft 64. With this structure, before the cutter 5 contacts the heat insulation strip, the pressure plate 65 contacts the heat insulation strip. The spring 66 allows the cutter 5 to descend continuously. When the cutter 5 contacts the heat insulation strip, the pressure plate 65 is pressed to clamp the heat insulation strip, preventing the heat insulation strip from jumping during cutting and improving its cutting accuracy.

[0033] Furthermore, the support assembly 1 includes a worktable 11, on which knife grooves 12 are evenly provided. A limiting plate 13 is fixedly connected to the upper surface of the worktable 11. A threaded rod 14 passes through the inside of the limiting plate 13. A partition 15 is fixedly connected to one end of the threaded rod 14. By setting the partition 15, the front and rear sides of the heat insulation strip can be auxiliaryly limited, which further improves the stability of the heat insulation strip placement and avoids the heat insulation strip tilting, which would cause deviation in its cutting.

[0034] Furthermore, the spacing between adjacent cutter grooves 12 is five centimeters to allow the cutter 5 to descend and ensure complete cutting of the heat insulation strip. The width of the cutter groove 12 is greater than the thickness of the cutter 5. Two sets of limiting plates 13, threaded rods 14 and partitions 15 are provided, and the two sets of limiting plates 13, threaded rods 14 and partitions 15 are symmetrically distributed on the front and rear sides of the worktable 11. The partitions 15 are used to limit the heat insulation strip on both sides.

[0035] Furthermore, a rectangular groove is provided on the limiting plate 13, and the width of the rectangular groove is equal to the diameter of the threaded rod 14. Two hand-tightened nuts are threaded to the outside of each threaded rod 14, and the two hand-tightened nuts abut against the two sides of the limiting plate 13 respectively. Two threaded rods 14 are fixedly connected to the outer wall of each partition 15. By loosening the hand-tightened nuts, the threaded rods 14 can be adjusted laterally. After the partition 15 is adjusted to a suitable position, the hand-tightened nuts are tightened to abut against the two sides of the limiting plate 13. The partition 15 can then complete the auxiliary limiting of the heat insulation strip.

[0036] Furthermore, a guide frame 46 is fixedly connected to the outer wall of the nut assembly 45, and the outer wall of the transmission sleeve 47 is rotatably connected to the guide frame 46 through a ball bearing. The intermediate transmission sleeve 47 is fixedly connected to the center of the transmission shaft 43. A tool 5 is fixedly connected to the center of the outer wall of each of the three transmission sleeves 47. A key is provided on the inner wall of the transmission sleeve 47. The key allows the transmission sleeve 47 and the transmission shaft 43 to slide in a circumferentially limited manner. This satisfies the horizontal sliding displacement of the transmission sleeve 47, and when the servo motor 44 drives the transmission shaft 43 to rotate, the key can be inserted to drive the transmission sleeve 47 to rotate, thereby driving the tool 5 to rotate.

[0037] Furthermore, the interior of the positioning sleeve 62 is rotatably connected to the transmission sleeve 47 via ball bearings. The top of the guide rod 63 has a T-shaped structure, and the lower surface of the top plate 3 is provided with a limiting groove adapted to the horizontal sliding of the guide rod 63. Through the sliding connection of the guide rod 63, the flexibility and stability of the displacement of the clamping components 6 at both ends are improved. The spring 66 abuts between the pressure plate 65 and the support plate 61, and the guide shaft 64 extends through to the top of the support plate 61. There are three sets of cutter 5 and clamping components 6, and the cutter 5 and clamping components 6 located in the middle position are fixedly connected to the outer wall of the transmission shaft 43, and at the same time, they are located at the center line of the transmission shaft 43.

[0038] Working principle: First, the positions of the two end cutters 5 are adjusted according to the cutting length of the heat insulation strip. The servo motor 44 is started, driving the bidirectional lead screw 42 to rotate. The horizontal displacement of the nut pair 45 drives the guide frame 46 to move. Furthermore, the transmission sleeve 47 drives the two side cutters 5 to move, thus achieving equidistant adjustment and cutting. After the adjustment is completed, the servo motor 44 is started, driving the transmission shaft 43 to rotate. Under the synchronous transmission of the transmission sleeve 47, the cutter 5 is driven to rotate. Furthermore, the hydraulic cylinder 2 controls the top plate 3 to descend, thus lowering the cutter 5. When the cutter 5 descends, it first contacts the heat insulation strip through the pressure plates 65 on both sides. As the top plate 3 continues to descend, the spring 66 contracts, and the cutter 5 continues to descend. At this time, the pressure plates 65 are continuously pressed, improving the pressing effect on the heat insulation strip. When the cutter 5 contacts the heat insulation strip, it can prevent the heat insulation strip from jumping, thereby improving its cutting accuracy.

[0039] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
