Description

Technical Field

[0001] This utility model relates to the technical field of steel pipe cutting equipment, and in particular to an auxiliary feeding mechanism for a square tube cutting machine. Background Technology

[0002] Traditional pipe cutting equipment typically uses a single dropping ramp to automatically unload the pipes using their own weight. For example, some simple pipe cutting machines rely solely on an inclined ramp to allow the cut pipes to slide into a storage area. However, this design is clearly inadequate for square pipes. Square pipes have a rectangular cross-section, and their shape results in a larger contact area with the dropping ramp as they slide down, increasing friction and making automatic unloading difficult or impossible.

[0003] Taking a square tube cutting auxiliary device and cutting mechanism disclosed in Chinese Patent Publication No. CN214023756U as an example, this patent mainly focuses on the fixing problem during the square tube cutting process. By setting up structures such as a fixing seat, a sliding device, a first limiting seat, and a second limiting seat, it achieves effective fixing of the square tube and improves the cutting quality. However, this patent does not address the issue of unloading the square tube after cutting. In actual production, the cut square tube may still affect the production process due to difficulties in unloading.

[0004] In actual production scenarios, when square tubes cannot be cut automatically, manual assistance is usually required. Workers need to manually move the square tubes from the cutting position to the storage area, which not only increases the labor intensity of workers but also poses certain safety hazards. During the handling process, workers may be injured due to improper operation. At the same time, manual handling is inefficient and cannot meet the needs of large-scale production, resulting in extended production cycles and increased production costs. Utility Model Content

[0005] In view of the shortcomings of the prior art, the purpose of this utility model is to provide an auxiliary feeding mechanism for a square tube cutting machine, so as to solve the problem that manual assistance is usually required when the square tube cannot be fed by itself.

[0006] An auxiliary feeding mechanism for a square tube cutting machine, the auxiliary feeding mechanism being installed below the cutting station, includes a fixed frame, a receiving tray, and a swinging assembly; The fixed frame is equipped with a receiving station and a unloading station. The receiving station is located below the cutting station, and the unloading station is located in front of the receiving station. The receiving tray is a long, trough-shaped structure that extends in the front-to-back direction. The swinging component is installed on the fixed frame and connected to the receiving tray. The swinging component drives the receiving tray to swing back and forth between the receiving station and the unloading station. The swinging assembly includes a swing arm and a telescopic rod. The bottom end of the swing arm is hinged to a fixed frame, and the top end is hinged to the bottom of the front end of the receiving tray. One end of the telescopic rod is hinged to the fixed frame, and the other end is hinged to the middle of the swing arm and to the side near the unloading station.

[0007] In this invention, the swinging assembly further includes a sliding bracket, which is disposed on the top of the fixed frame, and the middle part of the receiving tray slides against the sliding bracket.

[0008] Furthermore, the fixed frame is also provided with positioning brackets. There are two sets of positioning brackets symmetrically arranged on both sides of the sliding bracket. Limiting edges are provided on both sides of the receiving tray. When the receiving tray slides against the sliding bracket, the two sides of the receiving tray are limited by the positioning brackets pressing against the limiting edges.

[0009] Furthermore, a roller is rotatably provided on the top of the positioning bracket, and the positioning bracket is limited by pressing against the limiting edge through the roller.

[0010] In this utility model, the swinging assembly also includes a stroke hole for limiting the swing angle of the swing arm. An inclined baffle is provided on the side of the fixed frame near the unloading station. The stroke hole is provided on the inclined baffle. The swing arm passes through the stroke hole from bottom to top and is connected to the receiving tray. Buffer blocks are also provided at the front and rear ends of the stroke hole.

[0011] This utility model also includes a dust collection component, which includes a receiving hopper and a receiving trough. The receiving hopper is fixed on a fixed frame and located directly below the receiving station. The receiving trough is located at the bottom of the receiving hopper for collecting metal particles and dust. A dust suction port is also provided on the inner side of the receiving hopper.

[0012] In this invention, a protective cover is also provided on the fixing frame, and the protective cover is slidably fitted onto the top of the fixing frame by pulleys.

[0013] The beneficial effects of this utility model are: This utility model discloses an auxiliary feeding mechanism for a square tube cutting machine. By incorporating a swinging component, the receiving tray swings back and forth between the receiving and feeding stations, achieving stable feeding of square tubes. This solves the problem of difficult self-feeding caused by the large contact area and high friction between the square tube and the feeding channel in traditional feeding devices. It eliminates the need for manual handling, reduces worker labor intensity, eliminates safety hazards, and improves production efficiency. Simultaneously, the inclusion of positioning brackets and limiting edges prevents the receiving tray from detaching from the sliding bracket, improving the smoothness of the receiving tray's swing. The use of stroke holes and buffer blocks limits the swing angle of the swing arm and prevents violent impacts. The dust collection component effectively collects metal particles and dust generated during cutting, while the protective cover enhances safety and prevents dust from escaping.

[0015] This utility model provides an auxiliary feeding mechanism for a square tube cutting machine. To make the purpose, technical solution, and effects of this utility model clearer and more explicit, the following describes this utility model in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model.

[0016] In the description of this utility model, it should be understood that the directional descriptions, such as up, down, front, back, left, right, etc., indicate the directional or positional relationship based on the directional or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0017] Please see Figures 1 to 5 : This embodiment discloses an auxiliary feeding mechanism for a square tube cutting machine. The cutting machine includes a frame 1, a cutting device 2 installed at the front end of the frame 1 for cutting tubes, a pushing device 3 installed at the rear end of the frame 1 for pushing the tubes forward, and a guiding device 4 installed above the frame 1 for supporting the tubes. The auxiliary feeding mechanism 5 is installed below the cutting station 21 of the cutting device 2. The auxiliary feeding mechanism 5 includes a fixed frame 51, a receiving tray 52, and a swinging assembly 53. The fixed frame 51 is provided with a receiving station 511 and a feeding station 512. The receiving station 511 is located below the cutting station 21, and the feeding station 512 is located in front of the receiving station 511. The receiving tray 52 is a long, narrow, groove-shaped structure that extends in the front-to-back direction. The swinging assembly 53 is installed on the fixed frame 51 and... Connected to the receiving tray 52, the swinging component 53 drives the receiving tray 52 to swing back and forth between the receiving station 511 and the unloading station 512. Specifically, during cutting, the receiving tray 52 stays in the receiving station 511. Subsequently, the cut square tube falls into the receiving tray 52. ​​Then, the swinging component 53 drives the receiving tray 52 to swing forward. During the swinging process, the square tubes located in the receiving tray 52 are also thrown forward along the receiving tray 52. ​​This achieves stable unloading, and the thrown square tubes can be collected through the collection trough or enter the next processing step, eliminating the need for manual handling and improving production efficiency. It should also be noted that the cutting device 2, the pushing device 3, and the guiding device 4 in this embodiment are all existing technologies, and their specific structures and working principles will not be described in detail.

[0018] like Figure 2 As shown, the swing assembly 53 includes a swing arm 531 and a telescopic rod 532. The bottom end of the swing arm 531 is hinged to the fixed frame 51, and the top end is hinged to the bottom of the front end of the receiving tray 52, that is, one end near the unloading station 512. One end of the telescopic rod 532 is hinged to the fixed frame 51, and the other end is hinged to the middle of the swing arm 531 and one side near the unloading station 512. In addition, the swing assembly 53 also includes a sliding bracket 533, which is located at the center of the top of the fixed frame 51. The middle of the receiving tray 52 slides. When the telescopic rod 532 extends and retracts, it drives the swing rod 531 to swing back and forth around the hinge point at the bottom end. The top of the swing rod 531 drives the receiving tray 52 to swing back and forth. In addition, when the receiving tray 52 is located at the receiving station 511, the front end of the receiving tray 52 is lower than the middle of the receiving tray 52, that is, it is set at an angle. Under this structure, when the receiving tray 52 swings forward, the front end of the receiving tray 52 will continue to descend, while the rear end of the receiving tray 52 will tilt upward, forming a forward throwing action, thereby enabling the square tube to be thrown forward.

[0019] like Figure 4As shown, since the receiving tray 52 needs to perform a forward throwing motion, it is easy for the receiving tray 52 to detach from the sliding bracket 533. To avoid this, a positioning bracket 534 is also provided on the fixed frame 51. The positioning bracket 534 is provided in two sets and symmetrically arranged on both sides of the sliding bracket 533. In addition, a limiting edge 521 is provided on both sides of the receiving tray 52. ​​When the receiving tray 52 slides against the sliding bracket 533, the two sides of the receiving tray 52 are limited by the positioning bracket 534 pressing against the limiting edge 521, thereby preventing the receiving tray 52 from detaching from the sliding bracket 533. Preferably, in order to improve the smoothness of the receiving plate when it is thrown, a roller 535 is rotatably provided on the top of the positioning bracket 534. The positioning bracket 534 is limited by the roller 535 pressing against the limiting edge 521.

[0020] like Figure 5 As shown, the swing assembly 53 also includes a stroke hole 536 for limiting the swing angle of the swing rod 531. Specifically, an inclined baffle 513 is provided on the side of the fixed frame 51 near the unloading station 512. The stroke hole 536 is provided on the inclined baffle 513. The swing rod 531 passes through the stroke hole 536 from bottom to top and is connected to the receiving tray 52. ​​When the swing rod 531 swings to the front end of the stroke hole 536, the receiving tray 52 is located in the unloading station 512. When the swing rod 531 swings to the rear end of the stroke hole 536, the receiving tray 52 is located in the receiving station 511. In addition, rubber buffer blocks 514 are respectively provided at the front and rear ends of the stroke hole 536. When the swing rod 531 swings to the front and rear ends, it plays a buffering role, effectively absorbing the impact and preventing violent collisions.

[0021] In this embodiment, as Figure 3 As shown, metal particles and dust are generated when cutting square tubes. Therefore, a dust collection component 54 is also provided in the auxiliary feeding mechanism 5. The dust collection component 54 includes a receiving hopper 541 and a receiving groove 542. The receiving hopper 541 has a funnel-shaped structure and is fixed on the fixed frame 51 and located directly below the receiving station 511. The receiving groove 542 is located at the bottom of the receiving hopper 541 to collect metal particles and dust. In addition, a dust suction port 543 is provided on the inner side of the receiving hopper 541. Part of the metal particles and dust generated during cutting falls into the receiving groove 542 along the receiving hopper 541, and the other part is sucked away from the dust suction port 543. In order to prevent dust from floating outward and to improve safety, a protective cover 515 is also provided on the fixed frame 51. The protective cover 515 is slidably fitted to the top of the fixed frame 51 by pulleys.

[0022] The preferred embodiments of the present invention have been described in detail above. However, the present invention is not limited to the embodiments described. Those skilled in the art can make various equivalent modifications or substitutions without departing from the spirit of the present invention. All such equivalent modifications or substitutions are included within the scope defined by the claims of the present invention.
