Description

Technical Field

[0001] This utility model relates to the technical field of tube bar feeding mechanisms, specifically to a fixed-length feeding tube bar feeding mechanism. Background Technology

[0002] In today's rapidly developing manufacturing industry, the requirements for precision and efficiency in processing long and thin materials such as pipes and rods are increasing. In the pipe and rod cutting process, it is necessary to cut the pipes and rods to a precise length to meet the requirements of use. Precise control of the cutting position and feed rate plays a key role in ensuring processing accuracy.

[0003] Currently, when feeding tubular and bar stock, workers need to move the stock from the storage rack to the feeding position of the cutting equipment. During feeding, one end of the stock is manually aligned with the central axis of the cutting equipment, and the tilt angle is adjusted to ensure that the stock and the cutting equipment's feed direction are consistent. During manual feeding, workers also need to observe the operating status of the processing equipment and the processing condition of the stock. If any abnormalities are found (such as tool wear or stock vibration), feeding must be stopped immediately and the issue addressed. After one section of the stock is processed, workers continue to manually advance the stock, repeating the above operations until the entire stock is processed. Due to the varying skill levels of manual operation, it is difficult to guarantee the uniformity of feeding speed and the accuracy of position each time. For processing tasks with high precision requirements, errors in manual feeding can easily lead to unstable product quality.

[0004] Therefore, it is of great importance to design a fixed-length feed tube bar feeding mechanism to solve the above-mentioned defects. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model designs a fixed-length feeding mechanism for tubular rods. This mechanism aims to solve the technical problem that manual feeding in existing technologies is affected by differences in skill levels, making it difficult to guarantee the uniformity of feeding speed and the accuracy of position, which leads to unstable product quality.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A fixed-length feed tube bar feeding mechanism includes a frame, a feeding rack fixedly installed at the top of the back of the frame, an interval feeding component fixedly installed on the inner side of the frame, a conveying frame fixedly installed on the front of the frame, an mounting frame fixedly installed at the left end of the conveying frame, and a limit component fixedly installed on the top of the mounting frame.

[0008] The limiting assembly includes a guide frame fixedly connected to the rear end of the mounting frame. A limiting frame is fixedly installed on the right side of the guide frame. A fixed seat is fixedly installed at the bottom inner side of the guide frame. An adjusting seat is slidably connected to the top inner side of the guide frame. Conveying guide wheels are rotatably connected to the front sides of both the fixed seat and the adjusting seat. A motor is fixedly installed at the top of the mounting frame and on the back side of the guide frame. The drive end of the motor is fixedly connected to the central shaft of one set of conveying guide wheels. An adjusting screw is threadedly connected to the top of the guide frame. The bottom end of the adjusting screw is rotatably connected to the top of the adjusting seat.

[0009] As a preferred embodiment of this utility model, a rotating wheel is fixedly installed at the top end of the adjusting screw.

[0010] As a preferred embodiment of this utility model, limit guide rollers are installed at both the front and rear ends of the right side of the limiting frame, and slide blocks are rotatably connected to the upper and lower ends of the two sets of limit guide rollers. Multiple sets of slide blocks are slidably connected to the limiting frame through slide grooves, and springs are fixedly connected between the multiple sets of slide blocks and slide grooves.

[0011] As a preferred embodiment of this utility model, a feeding plate is fixedly connected to the top of the feeding rack, and limiting edges are fixedly connected to both the left and right ends of the feeding plate.

[0012] As a preferred embodiment of this utility model, the interval feeding assembly includes an interval feeding frame fixedly installed at the top of the inner side of the frame, a fixing sleeve fixedly connected to the middle of the interval feeding frame, a hydraulic rod fixedly installed at the bottom of the fixing sleeve, and a top feeding frame fixedly installed at the top of the hydraulic rod.

[0013] As a preferred embodiment of this utility model, both the left and right ends of the spaced feeding rack are provided with material blocking grooves, and both the left and right ends of the spaced feeding rack and the top feeding rack are provided with rack grooves.

[0014] As a preferred embodiment of this utility model, a guide plate is fixedly connected to the rear end of the top of the conveyor frame.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] 1. In this utility model, through the design of the feeding rack and the interval feeding component, the frame is installed at the feeding position of the cutting equipment. The operator places a certain number of tubes and bars on the feeding plate. The limiting edge limits the tubes and bars in the left and right directions to prevent them from deviating during the conveying process. The interval feeding component realizes the automatic interval feeding of tubes and bars, so that a single tube or bar automatically rolls into the conveying frame for conveying, which improves the efficiency and accuracy of feeding.

[0017] 2. In this utility model, through the design of the limiting component, a single tube or rod rolls into the conveyor frame and is conveyed to the left. The single tube or rod passes through the limiting frame and enters between two sets of conveying guide wheels. The limiting frame adaptively conforms to tubes or rods of different diameters for constraint, achieving stable limiting and guiding functions. It is then supported by the conveying guide wheels on the fixed base. At this time, the motor drives the conveying guide wheels to rotate, driving the tube or rod to be stably conveyed to the inside of the cutting equipment to achieve automatic feeding. When it is necessary to fix the cutting position of the tube or rod, the conveyor frame and motor are stopped first, and then the operator drives the adjusting screw by rotating the rotating wheel. The guide frame rotates with threads. Because the bottom end of the adjusting screw is rotatably connected to the top of the adjusting seat, the rotation of the adjusting screw will drive the adjusting seat to move downward, so that the two sets of conveying guide wheels clamp and fix the tube and bar material, controlling the feed amount of the tube and bar material. At the same time, it ensures that the tube and bar material is automatically aligned with the axis of the cutting equipment. It can be adapted to the tube and bar cutting device to perform fixed-length cutting, thereby eliminating the problems of uneven speed and inaccurate position of manual pushing. In addition, mechanical clamping is more stable than manual holding, reducing processing vibration. Operators do not need to continuously contact the moving tube and bar material, thus improving operational safety. Attached Figure Description

Detailed Implementation

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0025] Example: Please refer to Figures 1-5 This utility model provides a technical solution:

[0026] A fixed-length feed tube bar feeding mechanism includes a frame 1, a feeding rack 2 fixedly installed at the top of the back of the frame 1, an interval feeding assembly 3 fixedly installed on the inner side of the frame 1, a conveying rack 4 fixedly installed on the front of the frame 1, an mounting rack 5 fixedly installed at the left end of the conveying rack 4, and a limit assembly 6 fixedly installed on the top of the mounting rack 5.

[0027] First, in this embodiment, the specific structure of the limiting component 6 is as follows:

[0028] The limiting component 6 includes a guide frame 601 fixedly connected to the rear end of the mounting frame 5. A limiting frame 602 is fixedly installed on the right side of the guide frame 601. A fixed seat 603 is fixedly installed at the bottom inner side of the guide frame 601. An adjusting seat 604 is slidably connected to the top inner side of the guide frame 601. Conveying guide wheels 605 are rotatably connected to the front sides of both the fixed seat 603 and the adjusting seat 604. A motor 606 is fixedly installed on the top of the mounting frame 5 and on the back of the guide frame 601. The drive end of the motor 606 is connected to one set of the conveying guide wheels 605. The central shaft of 05 is fixedly connected. The top end of the guide frame 601 is threadedly connected to an adjusting screw 607. The bottom end of the adjusting screw 607 is rotatably connected to the top of the adjusting seat 604. A rotating wheel 608 is fixedly installed on the top end of the adjusting screw 607. The frame 1 is installed at the feeding position of the cutting equipment. The operator places a certain number of tubes and bars on the feeding rack 2. The interval feeding component 3 feeds the tubes and bars at intervals. A single tube or bar rolls into the conveyor frame 4 and is conveyed to the left. A single tube or bar passes through the limit frame 602 and enters the two... Between the conveyor guide rollers 605, the guide rollers 605 on the fixed base 603 support the tube / bar material. At this time, the motor 606 drives the conveyor guide rollers 605 to rotate, stably conveying the tube / bar material to the inside of the cutting equipment for automatic feeding. When it is necessary to fix the cutting position of the tube / bar material, the conveyor frame 4 and the motor 606 are stopped first. Then, the operator rotates the rotating wheel 608 to drive the adjusting screw 607 to rotate threaded on the guide frame 601. Since the bottom end of the adjusting screw 607 is rotatably connected to the top of the adjusting base 604, Therefore, the rotation of the adjusting screw 607 will cause the adjusting seat 604 to move downward, so that the two sets of conveying guide wheels 605 clamp and fix the tube and bar material, control the feed amount of the tube and bar material, and at the same time ensure that the tube and bar material is automatically aligned with the axis of the cutting equipment. It can be adapted to the tube and bar cutting device to perform fixed-length cutting, thereby eliminating the problems of uneven speed and inaccurate position of manual pushing. At the same time, mechanical clamping is more stable than manual holding, reduces processing vibration, and the operator does not need to continuously contact the moving tube and bar material, thus improving the safety of operation.

[0029] Furthermore, limit guide rollers 609 are installed at both the front and rear ends of the right side of the limiting frame 602. The upper and lower ends of the two sets of limit guide rollers 609 are rotatably connected to slide blocks 610. Multiple sets of slide blocks 610 are slidably connected to the limiting frame 602 through slide grooves 611. Springs 612 are fixedly connected between multiple sets of slide blocks 610 and slide grooves 611. When the tube or bar is conveyed from the conveyor frame 4 to the limiting frame 602, it will be immediately constrained by the limit guide rollers 609 installed at both the front and rear ends of the right side of the limiting frame 602. The limit guide rollers 609 can adaptively fit tube or bar of different diameters through the sliding connection of slide blocks 610 in slide grooves 611 and the elastic support of springs 612, thus achieving stable limiting and guiding functions. The elasticity of springs 612 not only enhances the adaptability of limit guide rollers 609 to tube or bar of different sizes, but also plays a buffering and protective role, reducing the impact of tube or bar on the limiting component 6 during the conveying process, and further ensuring the stability and accuracy of the conveying process.

[0030] Then, a feeding plate 201 is fixedly connected to the top of the feeding rack 2. Limiting edges 202 are fixedly connected to both the left and right ends of the feeding plate 201. The operator places a certain number of pipes and rods on the feeding plate 201. The limiting edges 202 limit the pipes and rods in the left and right directions to prevent them from deviating during the conveying process.

[0031] Secondly, the interval feeding assembly 3 includes an interval feeding rack 301 fixedly installed on the inner top of the frame 1. A fixing sleeve 302 is fixedly connected to the middle of the interval feeding rack 301. A hydraulic rod 303 is fixedly installed at the bottom of the fixing sleeve 302. A top feeding rack 304 is fixedly installed at the top of the hydraulic rod 303. Both the left and right ends of the interval feeding rack 301 are provided with baffle grooves 305. Both the left and right ends of the interval feeding rack 301 and the top feeding rack 304 are provided with rack grooves 306. The baffle grooves 305 limit the tubes and rods at the lowest end of the feeding plate 201. When feeding is required, the hydraulic rod... 303 lifts the top material rack 304 upwards. At this time, the top material rack 304 lifts the blocked tubes and bars through the rack groove 306 opened on it, so that they roll into the rack groove 306 inside the interval feeding rack 301. The hydraulic rod 303 then lowers the top material rack 304, while other tubes and bars continue to be blocked by the blocking groove 305. Then the top material rack 304 is lifted upwards again, so that the front end of the top material rack 304 lifts the tubes and bars on the interval feeding rack 301, so that they roll into the conveyor rack 4 for conveying. This realizes automatic interval feeding of tubes and bars, and improves the efficiency and accuracy of feeding.

[0032] Finally, a guide plate 401 is fixedly connected to the rear end of the top of the conveyor frame 4. Under the guidance of the guide plate 401, the tube and bar can roll smoothly onto the conveyor frame 4 for stable conveying.

[0033] In this embodiment, the specific implementation scenario is as follows: the frame 1 is installed at the feeding position of the cutting equipment. A certain number of tubes and bars are placed on the feeding plate 201 by the operator. The limiting edge 202 limits the tubes and bars in the left and right directions to prevent them from shifting during transport. The intermittent feeding assembly 3 feeds the tubes and bars at intervals. A single tube or bar rolls into the conveyor frame 4 and is conveyed to the left. A single tube or bar passes through the limiting frame 602 and enters between the two sets of conveying guide wheels 605. After the tube or bar is conveyed from the conveyor frame 4 to the limiting frame 602, it will... Immediately constrained by the limiting guide rollers 609 installed at both ends of the right side of the limiting frame 602, the limiting guide rollers 609 are slidably connected in the slide groove 611 through the slide block 610 and elastically supported by the spring 612. This allows them to adaptively conform to tubes and bars of different diameters, achieving stable limiting and guiding functions. The elasticity of the spring 612 not only enhances the adaptability of the limiting guide rollers 609 to tubes and bars of different sizes but also provides buffer protection, reducing the impact of the tubes and bars on the limiting assembly 6 during transport. The limiting guide rollers 609 are then secured by the fixed base 603. The guide roller 605 supports the tube / bar, and the motor 606 drives the guide roller 605 to rotate, steadily conveying the tube / bar to the inside of the cutting equipment for automatic feeding. When it is necessary to fix the cutting position of the tube / bar, the conveyor frame 4 and the motor 606 are stopped first. Then, the operator rotates the rotating wheel 608 to drive the adjusting screw 607 to rotate on the guide frame 601. Since the bottom end of the adjusting screw 607 is rotatably connected to the top of the adjusting seat 604, the rotation of the adjusting screw 607 will cause the adjusting seat 604 to move downward. The two sets of conveyor guide wheels 605 clamp and fix the tubes and bars, controlling the feed rate of the tubes and bars. At the same time, it ensures that the tubes and bars are automatically aligned with the axis of the cutting equipment. It can be adapted to the tube and bar cutting device for fixed-length cutting. The whole operation process is simple and convenient. This utility model can be adapted to the tube and bar cutting device for fixed-length cutting, eliminating the problems of uneven speed and inaccurate position of manual pushing, reducing processing vibration and improving operational safety. At the same time, it realizes automatic interval feeding of tubes and bars, improving the efficiency and accuracy of feeding.
