Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of profile cutting auxiliary equipment, specifically to a profile sawing and clamping device. Background Technology
[0002] In the production process of channel steel, channel steel is formed by rolling square billets. However, the rolled channel steel is generally eighty to ninety meters long and needs to be cut into finished channel steel of the required length by a sawing machine, such as cutting it into six-meter-long channel steel.
[0003] Existing equipment directly installs a sawing machine at the end of the conveyor rollers to saw channel steel. During sawing, a clamping device first clamps the channel steel to prevent it from shifting due to the sawing force, which could damage the saw or cause injury from flying channel steel. The existing clamping device is typically located between two conveyor rollers, pressing down on the channel steel to achieve clamping. During clamping, the channel steel below the clamping device is suspended in the air, meaning it's suspended between the two conveyor rollers. Often, after clamping, the channel steel is bent and undergoes plastic deformation. After the clamping device is released, the channel steel cannot fully return to a straight state, resulting in an uneven finished channel steel. The same problem exists in the cutting of other types of steel.
[0004] In summary, there is an urgent need for a profile sawing and clamping device to solve or at least partially solve the problems existing in the prior art. Utility Model Content
[0005] The purpose of this utility model is to provide a profile sawing and clamping device, which aims to solve the problem that existing clamping devices easily bend the profiles. The specific technical solution is as follows:
[0006] A profile sawing and clamping device includes a frame, a linear drive mechanism, a pressure plate, and a limiting mechanism. The fixed end of the linear drive mechanism is mounted on the frame along the height direction, and the driving end of the linear drive mechanism extends downward along the height direction. The pressure plate is fixedly connected to the driving end of the linear drive mechanism. The limiting mechanism includes a guide rod and an adjusting component. The first end of the guide rod is fixedly connected to the pressure plate, and the second end of the guide rod extends upward along the height direction through the frame. The adjusting component is movable and positioned at the upper end of the guide rod on the frame.
[0007] Furthermore, the adjusting component includes a sliding sleeve and a pin. The guide rod is provided with a first insertion hole arranged radially along the guide rod. The sliding sleeve is slidably sleeved on the guide rod in the height direction. The sliding sleeve is provided with a second insertion hole arranged radially along the sliding sleeve. The pin is simultaneously inserted into the first insertion hole and the second insertion hole for positioning.
[0008] Furthermore, multiple first sockets are arranged at intervals along the height direction of the guide rod, and a pin is inserted into one of the first sockets.
[0009] Furthermore, the adjusting component includes a first nut and a second nut, the upper end of the guide rod is provided with threads, the first nut and the second nut are both threadedly connected to the guide rod, and the first nut and the second nut are arranged close together.
[0010] Furthermore, two sets of guide rods and adjusting components are arranged, with the two sets of guide rods and adjusting components respectively arranged on both sides of the linear drive mechanism.
[0011] Furthermore, the linear drive mechanism is one of a hydraulic cylinder, a pneumatic cylinder, or an electric actuator.
[0012] Furthermore, the limiting mechanism also includes two limiting blocks, which are respectively arranged below both ends of the pressure plate.
[0013] Furthermore, the frame is provided with a limit groove, and a limit block is embedded in the limit groove.
[0014] On the other hand, this application also provides a profile sawing and pressing device, including a frame, a linear drive mechanism, a pressure plate and a limiting mechanism; the fixed end of the linear drive mechanism is installed on the frame along the height direction, and the pressure plate is fixedly connected to the drive end of the linear drive mechanism; the limiting mechanism includes a limiting block, which is installed on the frame and arranged below the pressure plate.
[0015] Furthermore, two limit blocks are arranged, one at each end of the pressure plate and the other below.
[0016] The application of the technical solution of this utility model has the following beneficial effects:
[0017] The linear drive mechanism drives the pressure plate and guide rod to move downwards and press them onto the steel profile. The linear drive mechanism continues to drive the pressure plate downwards, causing the steel profile to undergo elastic deformation until the adjusting component on the guide rod abuts against the frame. At this point, the guide rod and the linear drive mechanism are limited and cannot drive the pressure plate downwards, and the steel profile is compressed. After the steel profile is cut, the linear drive mechanism drives the pressure plate upwards, the steel profile is released, and it fully recovers its elastic deformation. Because of the setting of the adjusting component, when the linear drive mechanism drives the pressure plate to press the steel profile, it causes the steel profile to undergo a fixed and controllable deformation, thereby ensuring compression while preventing the steel profile from undergoing irreversible plastic deformation during compression.

[0028] To facilitate understanding of this invention, a more comprehensive description is provided below, along with preferred embodiments. However, this invention can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to provide a more thorough and complete understanding of the disclosure of this invention.
[0029] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.
[0030] Example 1:
[0031] See Figures 1-4 This embodiment provides a profile sawing and clamping device, including a frame 1, a linear drive mechanism 2, a pressure plate 3, and a limiting mechanism 4. The fixed end of the linear drive mechanism 2 is mounted on the frame 1 along the height direction, and the driving end of the linear drive mechanism 2 extends downward along the height direction. The pressure plate 3 is fixedly connected to the driving end of the linear drive mechanism 2. The limiting mechanism 4 includes a guide rod 41 and an adjusting member 42. The first end of the guide rod 41 is fixedly connected to the pressure plate 3, and the second end of the guide rod 41 extends upward through the frame 1 along the height direction. The adjusting member 42 is movable and positioned at the upper end of the guide rod 41 located on the frame 1.
[0032] Specifically, the frame 1 includes a base and a gantry frame. The gantry frame is fixedly connected to the base, and a multi-roller conveyor mechanism is also installed on the base. The gantry frame is arranged across the middle of the two conveyor rollers. A linear drive mechanism 2 is installed on the gantry frame. The drive end of the linear drive mechanism 2 passes through the gantry frame along the height direction and extends downward. The guide rod 41 passes through the gantry frame upward and is slidably guided to the gantry frame.
[0033] It should be noted that the sawing machine is mounted on the base and is located on the upstream side of the gantry frame, and the steel is conveyed by conveyor rollers.
[0034] It is known that the linear drive mechanism 2 drives the pressure plate 3 and guide rod 41 to move downwards and press them onto the steel profile. The linear drive mechanism 2 continues to drive the pressure plate 3 to move downwards, causing the steel profile to undergo elastic deformation until the adjusting part 42 on the guide rod 41 abuts against the frame 1. At this time, the guide rod 41 and the linear drive mechanism 2 are limited and cannot drive the pressure plate 3 to move downwards. The steel profile is pressed tightly. After the steel profile is cut, the linear drive mechanism 2 drives the pressure plate 3 to move upwards, the steel profile is released, and the elastic deformation is fully restored. Because of the setting of the adjusting part 42, when the linear drive mechanism 2 drives the pressure plate 3 to press the steel profile, the steel profile undergoes a fixed and controllable deformation, thereby ensuring that while pressing, the steel profile does not undergo irreversible plastic deformation during pressing.
[0035] Furthermore, the adjusting member 42 includes a sliding sleeve 421 and a pin 422. The guide rod 41 is provided with a first insertion hole 411 arranged radially along the guide rod 41. The sliding sleeve 421 is slidably sleeved on the guide rod 41 along the height direction. The sliding sleeve 421 is provided with a second insertion hole 4211 arranged radially along the sliding sleeve 421. The pin 422 is simultaneously inserted into the first insertion hole 411 and the second insertion hole 4211 for positioning.
[0036] It is known that when the pin 422 is inserted into the first insertion hole 411 and the second insertion hole 4211 at the same time, the sliding sleeve 421 is fixedly connected to the guide rod 41. When the linear drive mechanism 2 drives the pressure plate 3 to move downward, it will drive the guide rod 41 and the sliding sleeve 421 to move downward together until the sliding sleeve 421 abuts against the frame 1. At this time, the guide rod 41 and the pressure plate 3 are limited, thereby preventing the pressure plate 3 from moving downward too far and causing irreversible bending of the steel section.
[0037] Furthermore, multiple first insertion holes 411 are arranged at intervals along the height direction of the guide rod 41, and a pin 422 is inserted into one of the first insertion holes 411.
[0038] It is known that channel steel comes in different specifications. By arranging multiple first insertion holes 411 at intervals along the height direction of the guide rod 41, each first insertion hole 411 corresponds to a different limiting position of the pressure plate 3, thus making it suitable for clamping different types of steel profiles. At the same time, for the same type of steel profile, the clamping amount can be adjusted by aligning the sliding sleeve 421 and the pin 422 with different first insertion holes 411, so as to better clamp the steel profile while ensuring that it does not undergo plastic deformation.
[0039] Furthermore, two sets of guide rods 41 and adjusting members 42 are arranged, with the two sets of guide rods 41 and adjusting members 42 respectively arranged on both sides of the linear drive mechanism 2.
[0040] It can be seen that by arranging two sets of guide rods 41 and adjusting parts 42, the two ends of the pressure plate 3 are simultaneously limited, making the limiting of the pressure plate 3 more stable.
[0041] Furthermore, in this embodiment, the linear drive mechanism 2 is a hydraulic cylinder. The cylinder body is fixedly connected to the gantry frame of the machine frame 1, and the end of the piston rod away from the cylinder body is fixed to the pressure plate 3. The piston rod moves up and down relative to the cylinder body, thereby driving the pressure plate 3 to move up and down. In some other embodiments of this application, the linear drive mechanism 2 can also be a pneumatic cylinder or an electric push rod.
[0042] Furthermore, the limiting mechanism 4 also includes two limiting blocks 43, which are respectively arranged below both ends of the pressure plate 3.
[0043] It is known that both limit blocks 43 are arranged on the frame 1, and the two limit blocks 43 are located on both sides of the roller conveyor. When the pressure plate 3 presses down on the steel section, the steel section undergoes elastic deformation and is pressed tightly by the pressure plate 3 until the pressure plate 3 abuts against the limit blocks 43. At this time, the steel section has not yet undergone plastic deformation. Therefore, after the steel section is cut by the sawing machine, the pressure plate 3 is released, and the elastic deformation of the steel section is restored, so the steel section will not bend. The double limit by the adjusting part 42 on the guide rod 41 and the limit blocks 43 improves the stability of the limit and further ensures the normal operation of the pressing device.
[0044] It should be noted that limit blocks 43 of different thicknesses are arranged for different types of steel, such as steel with a thickness of 5 cm, 6 cm, 8 cm, etc.
[0045] Furthermore, a limit groove 11 is provided on the frame 1, and a limit block 43 is embedded in the limit groove 11.
[0046] It can be seen that by setting the limiting groove 11 on the frame 1, the limiting block 43 can be easily limited, preventing the limiting block 43 from moving during use and thus failing to perform its limiting function. In addition, the arrangement of the limiting groove 11 facilitates the operator in placing and positioning the limiting block 43. It should be noted that a fine-tuning shim is also provided in the limiting groove 11, which can be used to adjust the thickness of the limiting block 43.
[0047] The working principle and operation process of this utility model are as follows:
[0048] When the profile needs to be cut, the corresponding limit block 43 is selected according to the required profile specifications, and the position of the sliding sleeve 421 on the guide rod 41 is adjusted so that the position of the sliding sleeve 421 corresponds to the first insertion hole 411 at the corresponding profile pressing position. The pin 422 is simultaneously inserted into the first insertion hole 411 and the second insertion hole 4211 for positioning. The linear drive mechanism 2 drives the pressure plate 3 to move downward, and the pressure plate 3 drives the guide rod 41 and the sliding sleeve 421 to move downward together. The pressure plate 3 abuts against the profile, and the linear drive mechanism 2 continues to drive the pressure plate 3 to move downward, causing the profile to undergo elastic deformation until the sliding sleeve 421 abuts against the frame 1. At this time, the profile is pressed and has not yet undergone plastic deformation. After the profile is cut, the linear drive mechanism 2 drives the pressure plate 3 to move upward, and the profile is released. Because the profile only undergoes elastic deformation during the whole process, the elastic deformation of the profile is completely restored when the pressure plate 3 is released. During the pressing process, the limiting block 43 plays a redundant limiting role, and together with the guide rod 41 and the sliding sleeve 421, it achieves the limiting of the pressure plate 3, thereby improving the stability of the limiting.
[0049] Example 2:
[0050] See Figures 5-6 The difference between this embodiment and Embodiment 1 is that the adjusting component 42 in this embodiment is different from that in Embodiment 1. In this embodiment, the adjusting component 42 includes a first nut 423 and a second nut 424. The upper end of the guide rod 41 is provided with threads. The first nut 423 and the second nut 424 are both threadedly connected to the guide rod 41, and the first nut 423 and the second nut 424 are arranged close together. Specifically, the first nut 423 is arranged below the second nut 424.
[0051] It can be seen that when installing the first nut 423 and the second nut 424, the first nut 423 is first installed on the guide rod 41. The relative position of the first nut 423 and the guide rod 41 is adjusted to regulate the amount of compression of the steel section. The closer the first nut 423 is to the upper end of the guide rod 41, the greater the amount of compression of the steel section by the pressure plate 3; the farther the first nut 423 is from the upper end of the guide rod 41, the smaller the amount of compression of the steel section by the pressure plate 3. After the first nut 423 is adjusted to a suitable position, the second nut 424 is screwed in, so that the lower end face of the second nut 424 abuts against the upper end face of the first nut 423, thereby fixing the position of the first nut 423.
[0052] The remaining aspects are basically the same as in Example 1, and will not be repeated here.
[0053] Example 3:
[0054] See Figure 7 A profile sawing and pressing device includes a frame 1, a linear drive mechanism 2, a pressure plate 3, and a limiting mechanism 4. The fixed end of the linear drive mechanism 2 is mounted on the frame 1 along the height direction, and the pressure plate 3 is fixedly connected to the drive end of the linear drive mechanism 2. The limiting mechanism 4 includes a limiting block 43, which is mounted on the frame 1 and arranged below the pressure plate 3.
[0055] It is known that the linear drive mechanism 2 drives the pressure plate 3 to move downward to press the profile that needs to be sawed. By arranging a limit block 43 below the pressure plate 3, the pressure plate 3 is prevented from being over-pressed, which would cause irreversible plastic deformation of the profile.
[0056] Furthermore, two limit blocks 43 are arranged, with the two limit blocks 43 respectively arranged below both ends of the pressure plate 3.
[0057] By arranging two stops, the two ends of the pressure plate 3 are limited, thereby improving the stability of the pressure plate 3.
[0058] The remaining aspects are basically the same as in Example 1, and will not be repeated here.
[0059] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
