A longitudinal movement synchronization mechanism for rolling cutter head

Abstract

This utility model relates to the technical field of finned tube rolling equipment, and more particularly to a longitudinal movement synchronization mechanism for rolling cutters. It includes an adjusting groove within a mounting frame, a guide plate rotatably connected within the adjusting groove, and three equidistant, annular lifting grooves penetrating the adjusting groove on the mounting frame. Each lifting groove contains a longitudinal guide rod, and a guide slide rod is mounted on each longitudinal guide rod. The guide plate has a guide groove adapted to the guide slide rod. Upper and lower limiting grooves are provided on the side of the mounting frame, and adjusting rods slidably connected to the upper and lower limiting grooves are mounted on the side of the guide plate. Cutters are mounted at the bottom of each of the three longitudinal guide rods. This utility model allows the adjusting rods to be moved, causing the guide plate to rotate relative to the guide plate within the adjusting groove. The guide slide rods are guided by the guide grooves, pulling the longitudinal guide rods, thereby synchronously moving the three sets of cutters inward. This avoids the problem of inconsistent displacement distances caused by sequentially adjusting the cutters, effectively ensuring product forming consistency and improving product quality.

Description

Technical Field

[0001] This utility model relates to the technical field of finned tube rolling equipment, and in particular to a longitudinal movement synchronization mechanism for rolling cutter heads. Background Technology

[0002] As a core component in the heat exchange field, the rolling precision of finned tubes directly affects heat exchange efficiency and equipment reliability. During the rolling process of finned tubes, the synchronicity of the longitudinal movement of the cutter head is a key factor determining the uniformity of fin height and spacing.

[0003] Existing finned tube rolling equipment consists of a mounting frame, a cutter holder, a moving connection device, and a cutter holder position adjustment device. Because finned tubes with different forming angles are rolled, it is necessary to adjust the spatial position of the cutter holder relative to the mounting frame. The existing adjustment method involves turning the longitudinal adjusting bolt, as shown in the attached diagram. Figure 1 As shown, the tool holder moves relative to the mounting bracket under the drive of the thread. Due to the influence of thread clearance, bolt wear and differences in manual operation force, multiple tool holders (such as a three-tool holder structure) are difficult to move synchronously, resulting in deviations in the rolling angle and depth of each tool head on the finned tube. This directly affects the consistency of product forming and requires workers to repeatedly adjust and try and fail, resulting in high time and material costs. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a longitudinal movement synchronization mechanism for rolling cutter heads. This mechanism solves the technical problem that existing technologies rely on longitudinal adjustment bolts to adjust multiple cutter holders sequentially, which can lead to deviations in product forming due to variations in thread clearance, bolt wear, and manual operation force. The new mechanism achieves the goal of synchronously driving multiple cutter holders to move, ensuring consistent cutter holder movement.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a longitudinal movement synchronization mechanism for rolling cutter heads, including a mounting frame installed on a base, an adjustment groove is provided in the mounting frame, a guide plate is rotatably connected in the adjustment groove, three lifting grooves are provided in a ring at equal intervals through the adjustment groove on the mounting frame, a longitudinal guide rod is installed in each lifting groove, a guide slide rod is installed on the longitudinal guide rod, a guide groove adapted to the guide slide rod is provided on the guide plate, upper and lower limit grooves are provided on the side of the mounting frame, an adjustment rod is slidably connected in the upper and lower limit grooves on the side of the guide plate, and a cutter head is installed at the bottom of each of the three longitudinal guide rods.

[0006] A further improvement is that the adjustment groove is an annular structure groove, the guide plate is an annular structure adapted to the adjustment groove, and the adjustment groove is filled with lubricating grease.

[0007] A further improvement is that the longitudinal guide rod has a U-shaped groove that matches the guide plate, and the guide plate is engaged inside the U-shaped groove on the longitudinal guide rod.

[0008] A further improvement is that the guide groove is a strip-shaped groove whose end gradually approaches the inner ring of the guide plate, and the longitudinal guide rod is slidably connected inside the strip-shaped groove.

[0009] A further improvement is that the mounting frame includes a frame body mounted on a base, and an outer cover plate is bolted to the frame body.

[0010] A further improvement is that the cutter head includes a cutter holder connected to the inner end of the longitudinal guide rod, a cutter post is mounted on the cutter holder, and a cutter bar is mounted on the cutter post.

[0011] By employing the above technical solution, this utility model provides a longitudinal movement synchronization mechanism for rolling cutter heads, which has at least the following beneficial effects:

[0012] 1. This utility model, through the ingenious cooperation of components such as annular adjustment groove, guide plate, guide slide rod, and longitudinal guide rod, uses manual or external hydraulic power to drive the adjustment rod, which enables the guide plate to rotate relative to each other in the adjustment groove. With the help of the guide groove, the guide slide rod is guided to pull the longitudinal guide rod, thereby synchronously driving the three sets of cutter heads to move inward. This avoids the problem of different displacement distances caused by adjusting the cutter heads sequentially, effectively ensuring the consistency of product molding and improving product quality.

[0013] 2. The mounting frame of this utility model adopts a structure in which the frame body and the outer cover plate are connected by bolts. When the device needs maintenance, simply unscrew the bolts to separate the outer cover plate from the frame body, which allows for quick maintenance of the internal components of the mounting frame. The operation is simple and fast, reducing maintenance time and labor costs, and improving the convenience and efficiency of equipment maintenance. Attached Figure Description

[0024] 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.

[0025] The existing technology includes longitudinal adjusting rods b installed in equidistantly spaced lifting slots on a mounting frame a. Longitudinal adjusting bolts c are threaded onto the longitudinal adjusting rods b, and these bolts c are threaded into threaded holes within the lifting slots. A tool holder d is mounted at the bottom of the longitudinal adjusting rods b. By tightening the longitudinal adjusting bolts c, the longitudinal adjusting rods b are moved downwards sequentially to roll the finned tubes. However, the technology suffers from problems such as deviations in product forming due to variations in thread clearance, bolt wear, and manual operation force. Please refer to [reference needed]. Figures 1-4 This embodiment provides a longitudinal movement synchronization mechanism for rolling cutters, which can synchronously drive multiple cutter holders to move, ensuring consistent cutter holder movement. This longitudinal movement synchronization mechanism for rolling cutters includes a mounting frame 2 mounted on a base 1. The mounting frame 2 has an adjustment groove 3, and a guide plate 4 is rotatably connected within the adjustment groove 3. Three lifting grooves 5, arranged in a ring and equidistantly, penetrate the adjustment groove 3. A longitudinal guide rod 6 is installed in each lifting groove 5, and a guide slide rod 7 is installed on the longitudinal guide rod 6. The guide plate 4 has a guide groove 8 adapted to the guide slide rod 7. Upper and lower limit grooves 9 are provided on the side of the mounting frame 2, and an adjustment rod 10 slidably connected to the upper and lower limit grooves 9 is installed on the side of the guide plate 4. A cutter head 11 is installed at the bottom of each of the three longitudinal guide rods 6.

[0026] The adjusting groove 3 is an annular structure groove, and the guide plate 4 is an annular structure adapted to the adjusting groove 3, with grease filling the adjusting groove 3. A U-shaped structure groove adapted to the guide plate 4 is provided on the longitudinal guide rod 6, and the guide plate 4 is engaged inside the U-shaped structure groove on the longitudinal guide rod 6. The guide groove 8 is a strip-shaped structure groove whose end gradually approaches the inner ring of the guide plate 4. The longitudinal guide rod 6 is slidably connected inside the strip-shaped structure groove. When it is necessary to simultaneously adjust the positions of the three sets of cutter heads 11, the adjusting rod 10 is driven manually or by external hydraulic power to move downwards along the upper and lower limit grooves 9. At this time, the guide plate 4 rotates relative to the guide plate 4 within the adjusting groove 3, thereby causing the guide slide rod 7, guided by the guide groove 8, to pull the longitudinal guide rod 6 downwards along the lifting groove 5, thus simultaneously driving the three sets of cutter heads 11 to move inwards synchronously, achieving synchronous movement of the three sets of cutter heads 11. This avoids sequential adjustment of the cutter heads 11, which could lead to differences in the displacement distance of the cutter heads 11, thus affecting the consistency of product molding.

[0027] To facilitate maintenance of the device, the mounting frame 2 includes a frame body 21 mounted on the base 1. An outer cover plate 22 is bolted to the frame body 21. When maintenance is required, the outer cover plate 22 and the frame body 21 can be separated by unscrewing the bolts, thereby allowing for quick maintenance of the internal components of the mounting frame 2. The operation is simple and fast.

[0028] The cutter head 11 includes a cutter holder 111 connected to the inner end of the longitudinal guide rod 6, a cutter post 112 mounted on the cutter holder 111, and a cutter bar 113 mounted on the cutter post 112.
