Description
Technical Field
[0001] This utility model belongs to the field of refrigerator handle tube processing technology, specifically a refrigerator handle tube straight-line pattern drawing device. Background Technology
[0002] The refrigerator handle tube is a component of the refrigerator handle, usually in the shape of a tube. Common types include round tubes and square tubes. Round tubes have a comfortable feel, no sharp edges, and a smooth appearance; square tubes appear more rigid with sharp edges and are more commonly seen on refrigerators with modern minimalist or industrial designs, giving a simple and elegant feel. The refrigerator handle tube provides users with a convenient point of force, making it easy to open and close the refrigerator door, especially for some larger and heavier refrigerator doors, where the presence of the handle tube allows users to operate it with less effort.
[0003] Straight-line textured finish on refrigerator handles is a surface treatment process that typically uses mechanical processing or chemical etching to create a straight-line pattern on the handle surface. This adds a unique texture and decorative effect to the refrigerator handle, making the refrigerator look more refined and upscale, and easier to match with modern home décor styles, thus enhancing the overall aesthetics of the refrigerator. Compared to a smooth handle surface, the straight-line textured finish increases the friction between the hand and the handle, making it easier to apply force when opening and closing the refrigerator door and reducing the risk of slipping. This anti-slip performance is especially important for large or heavy refrigerator doors.
[0004] In existing technology, making straight-line patterned refrigerator handle tubes requires flattening one end of a long tube (over 2.5m in length) with a special machine, inserting it into a tube drawing machine, clamping the flattened part, and then drawing the pattern. This requires large-scale drawing equipment and space. Many handle factories are unwilling to invest in production due to space and production capacity reasons. Secondly, the straight-line patterned refrigerator handle tubes processed in this way need to be cut off at both ends, which wastes raw materials.
[0005] Therefore, a straight-line patterned device for refrigerator handle tubes is proposed to address the above problems. Utility Model Content
[0006] To address the problems mentioned in the background art, this utility model provides a refrigerator handle tube straight-line drawing device, which has the advantages of straight-line drawing on short tubes without the need for large equipment and space, and without the need for cutting off the head or tail, thus avoiding some waste of raw materials.
[0007] To achieve the above objectives, this utility model provides the following technical solution: a refrigerator handle tube straight-line drawing device, including a worktable, a hydraulic cylinder installed on the top of the worktable, a movable seat connected to the piston rod of the hydraulic cylinder, a push rod installed on the side of the movable seat away from the hydraulic cylinder, a fixed seat fixed on the top of the worktable, the fixed seat being positioned corresponding to the movable seat, a straight-line drawing mold installed on the fixed seat, the position of the straight-line drawing mold being corresponding to the position of the push rod.
[0008] Preferably, support legs are fixedly connected to the four corners of the bottom of the workbench, and cross braces are fixedly connected between adjacent support legs.
[0009] Preferably, a slide rail is installed on the worktable at a position corresponding to the movable seat, and the slide rail is slidably connected to the movable seat.
[0010] Preferably, the movable seat has symmetrically arranged guide holes, and a guide rod is disposed in the guide hole, with the end of the guide rod fixedly connected to the fixed seat.
[0011] Preferably, a threaded groove is provided on the movable seat at a position corresponding to the push rod, and a threaded post is threadedly connected to the threaded groove, and the threaded post is fixedly connected to the push rod.
[0012] Preferably, the push rod includes a pushing section and an extending section, the pushing section is fixedly connected to the extending section, and a threaded post is fixedly connected to the end of the pushing section away from the extending section. The diameter of the pushing section is the same as the outer diameter of the handle tube, and the diameter of the extending section is slightly smaller than the inner diameter of the handle tube.
[0013] Preferably, a traction release assembly is installed on the side of the fixed seat away from the movable seat, and the position and structure of the traction release assembly correspond to the position of the straight-line drawing mold.
[0014] The traction release assembly includes two sets of driving wheels and driven wheels, with the two driving wheels connected by a linkage rod. One of the driving wheels is connected to a drive motor via a motor shaft.
[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0027] 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.
[0028] like Figures 1 to 5 As shown, this utility model provides a straight-line drawing device for refrigerator handle tubes, including a workbench 1, a hydraulic cylinder 2 installed on the top of the workbench 1, a movable seat 3 connected to the piston rod of the hydraulic cylinder 2, a push rod 4 installed on the side of the movable seat 3 away from the hydraulic cylinder 2, a fixed seat 5 fixed on the top of the workbench 1, the position of the fixed seat 5 corresponding to the position of the movable seat 3, a straight-line drawing mold 6 installed on the fixed seat 5, the position of the straight-line drawing mold 6 corresponding to the position of the push rod 4. By using the hydraulic cylinder 2 to push the short tube through the straight-line drawing mold 6, the short tube can be drawn with straight lines. No large equipment or space is required, and there is no need to cut off the head or tail, thus avoiding waste of raw materials.
[0029] Specifically, support legs 7 are fixedly connected to the four corners of the bottom of the workbench 1, and cross braces 8 are fixedly connected between adjacent support legs 7.
[0030] Furthermore, a slide rail 9 is installed on the workbench 1 at the position corresponding to the movable seat 3. The slide rail 9 is slidably connected to the movable seat 3 and is used to support the movable seat 3 to move on the workbench 1.
[0031] Furthermore, the movable seat 3 is provided with symmetrically arranged guide holes 10, and a guide rod 11 is provided in the guide hole 10. The end of the guide rod 11 is fixedly connected to the fixed seat 5 to ensure the stability of the movable seat 3 when it moves.
[0032] It is worth noting that a threaded groove 12 is provided on the movable seat 3 at the position corresponding to the push rod 4. The threaded groove 12 is threadedly connected to a threaded post 13, which is fixedly connected to the push rod 4, so that the push rod 4 is movably connected to the movable seat 3, making it easy to disassemble and assemble the push rod 4.
[0033] It is worth noting that the push rod 4 includes a pushing section 401 and an extending section 402. The pushing section 401 is fixedly connected to the extending section 402. The end of the pushing section 401 away from the extending section 402 is fixedly connected to the threaded post 13. The diameter of the pushing section 401 is the same as the outer diameter of the handle tube, and the diameter of the extending section 402 is slightly smaller than the inner diameter of the handle tube, so that the extending section 402 extends into the short tube to support the short tube and prevent deformation during pushing.
[0034] It is worth mentioning that a traction release component 14 is installed on the side of the fixed seat 5 away from the movable seat 3, and the position and structure of the traction release component 14 correspond to the position of the straight-line drawing mold 6.
[0035] The traction release assembly 14 includes two sets of driving wheels 1401 and driven wheels 1402. The two driving wheels 1401 are connected by a connecting rod 1403. One of the driving wheels 1401 is connected to a drive motor 1404 through a motor shaft. After the short tube passes through the straight-line drawing mold 6, the traction release assembly 14 is used to release the short tube from the top rod 4. There is no need for manual unloading of the short tube, which improves the efficiency of the straight-line drawing work.
[0036] Hydraulic cylinder 2 and drive motor 1404 are existing technologies and will not be described in detail. In addition, this utility model also includes power supply, controller and switch, which are not the main technical points of this patent and will not be described in detail.
[0037] Working principle and process: One end of the handle tube is sleeved onto the push rod 4. The extension section 402 of the push rod 4 extends into the handle tube, and the end face of the pushing section 401 abuts against the tube wall of the handle tube to position it. The hydraulic cylinder 2 is activated, extending and causing the movable seat 3 to move, thus pushing the handle tube towards the straight-line drawing mold 6. When the handle tube passes through the straight-line drawing mold 6, straight-line drawing can be performed. The drive motor 1404 of the traction release component 14 is activated, causing the drive wheel 1401 to rotate. The driven wheel 1402 clamps and rotates the handle tube. When the handle tube enters the straight-line drawing mold 6 at one end of the push rod 4, the hydraulic cylinder 2 retracts. At this time, the traction release component 14 drives the handle tube to continue forward, while the push rod 4 will disengage from the handle tube to reset. The handle tube continues to move forward until it disengages from the straight-line drawing mold 6, thus completing the straight-line drawing of the handle tube. Using small equipment to perform straight-line drawing on short tubes eliminates the need for large equipment and space, and also eliminates the need for cutting off the head and tail, thus avoiding waste of raw materials.
