Description

Technical Field

[0001] This utility model relates to the field of sawing machine technology, and in particular to a positioning and conveying mechanism for a sawing machine. Background Technology

[0002] A sawing machine is a common metal processing equipment widely used for cutting steel pipes, stainless steel pipes, aluminum profiles, and other tubular materials to a fixed length. To improve processing efficiency, existing technologies typically employ multi-tube sawing machines, clamping multiple tubes at once and cutting them to a uniform length. When mass-producing products of the same specification, this type of equipment effectively reduces the need for sequential cutting of individual tubes, thus improving processing efficiency.

[0003] However, existing multi-pipe sawing machines generally have the following shortcomings: when the pipes to be processed are of inconsistent lengths, existing equipment can usually only meet the batch cutting of the same length, and cannot simultaneously cut pipes of different lengths. If users need pipes of different lengths, workers need to manually adjust the extension length of the pipes one by one or batch by batch and cut them in stages. This operation method not only increases the labor intensity of workers, but also reduces production efficiency, which is particularly evident in multi-variety, small-batch processing scenarios. Utility Model Content

[0004] The purpose of this utility model is to solve the shortcomings of low cutting efficiency and high labor intensity of pipes of different lengths in the existing technology, and to propose a positioning and conveying mechanism for a sawing machine.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A sawing machine positioning and conveying mechanism includes a conveyor, a first pressing mechanism above the end of the conveyor, a support platform behind the conveyor, at least two second pressing mechanisms above the support platform, the plurality of second pressing mechanisms being arranged along the width direction of the conveyor, and a sawing machine being arranged between the first pressing mechanism and the second pressing mechanisms.

[0007] The first pressing mechanism includes a second lifting actuator arranged vertically in the direction of movement, and a pressure roller is rotatably mounted on the lifting end of the second lifting actuator.

[0008] The second lifting actuator is either a cylinder or an electric telescopic rod.

[0009] The second pressing mechanism includes a first lifting actuator arranged vertically in the direction of movement, and a pressure plate is fixedly installed on the lifting end of the first lifting actuator.

[0010] The first lifting actuator is either a cylinder or an electric telescopic rod.

[0011] The conveyor is a roller conveyor.

[0012] The support platform is provided with at least two parallel scale lines.

[0013] The support platform is provided with at least two slide rails, which are arranged along the conveying direction of the rod. Each slide rail is slidably connected to a stop block, and the stop block is provided with a pointer pointing to the scale line.

[0014] The support platform is equipped with a reset mechanism for each stop, and the reset mechanism can generate a thrust that moves the stop toward the conveyor.

[0015] The reset mechanism includes a first fixed pulley and a second fixed pulley that are rotatably connected to the support platform. The second fixed pulley is located upstream of the support platform, and the first fixed pulley is located downstream of the support platform. The stop block is connected to a pull rope, and the other end of the pull rope passes around the second fixed pulley and the first fixed pulley in sequence and is connected to a counterweight. A guide rod is installed between the counterweight and the ground to guide the counterweight vertically.

[0016] The positioning and conveying mechanism for a sawing machine proposed in this utility model has the following advantages: Through the above-mentioned structural arrangement, by utilizing the unified drive of the conveyor and the sequential action of multiple second clamping mechanisms, multiple rods can be positioned to different cutting lengths during a single conveying process. After all rods reach the set position, they are uniformly locked by the first clamping mechanism, and then the sawing machine completes the cutting. This method avoids the tedious operation of manually adjusting the length of each rod individually, reducing labor intensity. At the same time, it can achieve synchronous cutting of pipes of different lengths, improving cutting efficiency and processing accuracy, and is suitable for processing needs of multiple varieties and small batches.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0021] Reference Figures 1-2 A sawing machine positioning and conveying mechanism includes a conveyor 1, a first pressing mechanism 16 is provided above the end of the conveyor 1, a support platform 10 is provided behind the conveyor 1, at least two second pressing mechanisms 17 are provided above the support platform 10, the multiple second pressing mechanisms 17 are arranged along the width direction of the conveyor 1, and a sawing machine 3 is provided between the first pressing mechanism 16 and the second pressing mechanism 17.

[0022] When multiple rods need to be cut, the rods are first placed on conveyor 1. After conveyor 1 starts, it simultaneously pushes the multiple rods backward along the conveying direction. As conveyor 1 runs, when the first rod moves to the predetermined length position, its corresponding second clamping mechanism 17 activates, clamping and fixing the first rod, thus preventing the rod from continuing to move with conveyor 1. That is, the rod clamped by the second clamping mechanism 17 slides relative to conveyor 1 and will not continue to be conveyed backward with conveyor 1. Conveyor 1 continues to run, and when the second rod reaches the set length position, another set of second clamping mechanisms 17 activates to clamp the second rod. This process continues, and when the third and subsequent rods reach the required length, they are individually clamped and positioned by the corresponding second clamping mechanism 17. After all the rods have been sequentially positioned by the second clamping mechanisms 17, the first clamping mechanism 16 activates as a whole, clamping and locking all the rods simultaneously. Conveyor 1 stops running, and sawing machine 3 begins to cut the multiple rods.

[0023] With the above structural setup, the unified drive of the conveyor 1, combined with the sequential action of multiple second clamping mechanisms 17, allows multiple rods to be positioned to different cutting lengths during a single conveying process. Once all rods reach their set positions, they are uniformly locked by the first clamping mechanism 16, and then the sawing machine 3 completes the cutting. This method avoids the tedious manual adjustment of rod lengths one by one, reducing labor intensity. Simultaneously, it enables simultaneous cutting of pipes of different lengths, improving cutting efficiency and processing accuracy, and is suitable for processing diverse products in small batches.

[0024] The first pressing mechanism 16 includes a second lifting actuator 13 arranged vertically in the direction of movement, and a pressure roller 2 is rotatably mounted on the lifting end of the second lifting actuator 13; the second lifting actuator 13 is one of a cylinder or an electric telescopic rod; the second pressing mechanism 17 includes a first lifting actuator 4 arranged vertically in the direction of movement, and a pressure plate 5 is fixedly mounted on the lifting end of the first lifting actuator 4; the first lifting actuator 4 is one of a cylinder or an electric telescopic rod; the conveyor 1 is a roller conveyor.

[0025] Conveyor 1 is a roller conveyor, which can simultaneously transport multiple rods backward during operation. When the first rod moves to the preset cutting length, the corresponding second pressing mechanism 17 is activated. The second pressing mechanism 17 includes a first lifting actuator 4 arranged vertically, and a pressure plate 5 is fixedly installed on the lifting end of the first lifting actuator 4. After the pressure plate 5 presses down, it presses and fixes the first rod, preventing it from continuing to move with the conveyor 1. As the conveyor 1 continues to operate, when the remaining rods reach the set length in sequence, the other second pressing mechanisms 17 are activated respectively, and their respective first lifting actuators 4 drive the pressure plates 5 to press and position the corresponding rods one by one. After all the rods have been positioned in sequence, the first pressing mechanism 16 is activated as a whole. The first pressing mechanism 16 includes a second lifting actuator 13 arranged vertically, and a pressure roller 2 is rotatably installed on the lifting end of the second lifting actuator 13. When the pressure roller 2 presses down, it can simultaneously press all the rods as a whole. At this point, conveyor 1 stops running, and sawing machine 3 begins to cut multiple rods simultaneously, thus completing sawing operations of different lengths.

[0026] The support platform 10 is provided with at least two parallel scale lines 14; the support platform 10 is provided with at least two slide rails 15, the slide rails 15 are arranged along the conveying direction of the rod, and each slide rail 15 is slidably connected to a stop block 6, the stop block 6 is provided with a pointer pointing to the scale line 14.

[0027] In this design, the support platform 10 has multiple parallel scale lines 14 to indicate different cutting lengths. The support platform 10 also has multiple slide rails 15 along the rod conveying direction, each slide rail 15 having a stop block 6 slidably connected to it. Workers determine the rod length by observing the position of the pointer on the stop block 6.

[0028] Each stop 6 on the support platform 10 is equipped with a reset mechanism. The reset mechanism can generate a thrust that moves the stop 6 toward the conveyor 1. The reset mechanism includes a first fixed pulley 9 and a second fixed pulley 11 that are rotatably connected to the support platform 10. The second fixed pulley 11 is located upstream of the support platform 10, and the first fixed pulley 9 is located downstream of the support platform 10. The stop 6 is connected to a pull rope 18. The other end of the pull rope 18 passes around the second fixed pulley 11 and the first fixed pulley 9 in sequence and is connected to a counterweight 8. A guide rod 7 is installed between the counterweight 8 and the ground to guide the counterweight 8 vertically.

[0029] The counterweight 8 moves continuously downwards under gravity, generating a pushing force on the stop block 6 towards the conveyor 1 via the pull rope 18. To ensure the stable vertical operation of the counterweight 8, a guide rod 7 is installed between the counterweight 8 and the ground. The guide rod 7 vertically guides the counterweight 8, ensuring a smooth descent. Thus, after the stop block 6 is pushed away from its original position and the cutting is completed, the reset mechanism automatically pulls the pull rope 18 under the action of the counterweight 8, thereby restoring the stop block 6 to its initial position close to the conveyor 1. This eliminates the need for manual reset and improves ease of use.

[0030] Of course, this device can also adopt other working methods. For example, a locking bolt can be set on the stop block 6. The worker first pulls the stop block to the required length and fixes the position of the stop block by locking the bolt. The conveyor conveys the rod over. When the rod comes into contact with the stop block, the position of the rod will be blocked. The blocked rod slides relative to the conveyor, and the remaining rods continue to be conveyed backward. In addition, a corresponding guide mechanism can be set as needed to make the rod move backward stably. Any improvement made based on this application is within the protection scope of this application.

[0031] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any technical solution, concept, or design obtained by those skilled in the art by making equivalent substitutions or changes based on the technical solution and utility model concept disclosed in the present utility model should be included within the protection scope of the present utility model.
