Description

Technical Field

[0001] This utility model relates to the field of steel section sawing technology, and in particular to a steel section sawing positioning device. Background Technology

[0002] Section steel is a type of bar steel with specific cross-sectional shape and size. Based on the different cross-sectional shapes, section steel can be divided into two main categories: simple section steel and complex section steel. With its rich variety of shapes and sizes, section steel can fully meet the special material requirements of many fields such as engineering structures and machinery manufacturing. For example, common section steels such as I-beams, channel steel, and angle steel have extremely wide applications in building structure construction, bridge engineering construction, machinery and equipment manufacturing, and vehicle manufacturing, and have become an indispensable key material for modern industrial development and infrastructure construction.

[0003] In the production of structural steel, in order to improve the yield, structural steel is usually rolled into strips of multiple lengths. However, in actual applications, customers often require delivery of fixed dimensions of different lengths, or for the sake of subsequent processing, they need to use single-length structural steel. Therefore, it is necessary to cut the multiple-length structural steel strips to a fixed length to ensure that the delivered structural steel dimensions meet the customer's requirements. However, the existing fixed sawing structure has obvious limitations. It can only meet the sawing requirements of a single length dimension and cannot flexibly adjust the sawing length according to actual needs. This affects the overall efficiency of structural steel sawing to some extent.

[0004] Furthermore, in the steel section sawing operation, roller conveyors are needed to transport the steel sections. Due to the lack of effective constraint between the steel sections and the roller conveyors, the steel sections are prone to deviation during transportation. Once the steel sections deviate, they will be in an inclined state during sawing, which will undoubtedly have an adverse effect on the quality of the steel sections after sawing. Therefore, this application provides a steel section sawing positioning device to meet the requirements. Utility Model Content

[0005] The technical problem to be solved by this utility model is to provide a steel section sawing positioning device to solve the problem that the existing fixed sawing structure has obvious limitations, can only meet the sawing requirements of a single length dimension, and the steel section is prone to displacement during transportation, which affects the quality of the sawn steel section.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0007] A steel section cutting and positioning device includes a sawing machine, a feeding rack on one side of the sawing machine, a receiving rack on the side of the sawing machine away from the feeding rack, and a receiving rack on one side of the receiving rack; a guiding mechanism for assisting in guiding the steel section during transportation, the guiding mechanism being connected to the receiving rack; and a positioning mechanism for abutting the end of the steel section to control the length of the steel section being cut, the positioning mechanism being connected to the receiving rack.

[0008] Optionally, the guiding mechanism includes a base fixed between the two beams of the receiving frame. The base has multiple movable slots symmetrically arranged inside. A connecting shaft is slidably connected inside the movable slot, and a contact wheel is rotatably connected to the top of the connecting shaft.

[0009] Optionally, a turntable is rotatably connected to the bottom of the base. Two constraint grooves are symmetrically opened inside the turntable. A bearing is slidably connected inside each constraint groove. A connecting arm is fixedly connected to the shaft of the bearing. An adjusting arm is fixedly connected to one end of the connecting arm. The connecting shaft passes through the movable groove and is fixedly connected to the adjusting arm.

[0010] Optionally, the central axis of the turntable is fixedly connected to a swing arm through the base, and a handle is rotatably connected to the upper surface of the swing arm.

[0011] Optionally, a shaft is inserted into the swing arm, and multiple insertion holes are equally spaced inside the base, with the bottom end of the shaft inserted into the insertion hole.

[0012] Optionally, a retaining ring is fixedly sleeved on the outside of each of the multiple connecting shafts, the bottom of the retaining ring is in contact with the upper surface of the base, and two flat parts are symmetrically arranged on the retaining ring.

[0013] Optionally, the positioning mechanism includes a mounting base installed on the receiving rack, two side plates are symmetrically fixedly connected to both sides of the mounting base, a lead screw is threaded between the two side plates, and a stop plate is rotatably connected to one end of the lead screw.

[0014] Optionally, a handwheel is fixedly connected to the end of the lead screw away from the abutment plate, and two nuts are threadedly connected to the outer side of the lead screw, with the nuts abutting against the side plate.

[0015] Optionally, the bottom of the mounting base is fixedly connected to a plug plate, and multiple slots are symmetrically opened on the two side beams of the receiving frame, with the plug plate inserted into two corresponding slots.

[0016] Optionally, a sliding rod is slidably connected inside the two side plates, and one end of the sliding rod is fixedly connected to the abutment plate.

[0017] Compared with the prior art, this utility model has at least the following beneficial effects:

[0018] In the above solution, the steel section sawing positioning device not only has the function of flexibly adjusting the position of the positioning mechanism, which can accurately adapt to the sawing operation requirements of steel sections of different lengths, but also plays a key auxiliary guiding role in the steel section conveying process, effectively preventing conveying deviation and ensuring sawing quality.

[0019] Multiple slots and inserts symmetrically arranged on the receiving rack work together to form a stable positioning mechanism. This design is simple in structure and has excellent stability. Combined with a flexibly adjustable backing plate, it achieves secondary precise calibration. This design not only greatly expands the application range of steel section positioning, but also achieves a new level of positioning accuracy.

[0020] In addition, the multiple contact wheels are equipped with a conical structure design. This design not only provides reliable auxiliary guidance during the steel section conveying process, but also ensures the smooth pushing and unloading of the steel section after sawing. It is worth mentioning that the spacing between the contact wheels can be flexibly adjusted according to actual needs, thereby meeting the guidance requirements of steel sections of different specifications during the conveying process, significantly improving the versatility and adaptability of the equipment.

Additionally, the term "based on" can be understood not necessarily to convey an exclusive set of factors, but rather, alternatively, depending at least partly on the context, to allow for the presence of other factors that are not necessarily explicitly described.

[0034] It is understood that the meanings of “on”, “above”, and “above” in this utility model should be interpreted in the broadest manner, such that “on” not only means “directly on” something, but also includes the meaning of being “on” something with an intervening feature or layer, and that “above” or “above” not only means “on” something, but also includes the meaning of being “on” something without an intervening feature or layer.

[0035] Furthermore, spatially related terms such as “below,” “under,” “lower,” “above,” and “upper” are used herein for convenience to describe the relationship of one element or feature to one or more other elements or features, as illustrated in the accompanying drawings.

[0036] like Figures 1 to 6 As shown, an embodiment of this utility model provides a steel section sawing and positioning device, including a sawing machine 1, a feeding rack 2 on one side of the sawing machine 1, a receiving rack 3 on the side of the sawing machine 1 away from the feeding rack 2, and a receiving rack 4 installed on the side of the receiving rack 3. Both the feeding rack 2 and the receiving rack 3 are roller conveyors, which not only have strong load-bearing capacity but also can cooperate with the sawing machine 1 to saw the steel section. The receiving rack 4 facilitates the collection of the sawn steel section for subsequent transfer. A guiding mechanism is used to assist in guiding the steel section during transportation. The guiding mechanism is connected to the receiving rack 3 and can accurately adapt to the sawing requirements of steel sections of different lengths. A positioning mechanism is used to abut the end of the steel section to control the length of the steel section sawing. The positioning mechanism is connected to the receiving rack 3 and can assist in guiding the steel section during transportation to avoid deviation during transportation and ensure sawing quality.

[0037] like Figures 2 to 5As shown, the guiding mechanism includes a base 501 fixed between the two side beams of the receiving frame 3. Multiple movable slots 502 are symmetrically arranged inside the base 501. A connecting shaft 503 is slidably connected inside each movable slot 502. A contact wheel 504 is rotatably connected to the top of the connecting shaft 503. The movable slots 502 not only provide space for the connecting shaft 503 to move but also limit its movement, preventing the contact wheel 504 from shifting during adjustment. The contact wheel 504 is made of cast iron or steel to ensure structural strength and reduce wear. The upper half of the contact wheel 504 is inclined, a design that avoids complete contact with the steel section, allowing for the pushing and unloading of the steel section after sawing. Retaining rings 505 are fixedly sleeved on the outside of each of the multiple connecting shafts 503. The bottom of the retaining ring 505 is flush with the upper surface of the base 501. The contact wheel 504 is symmetrically arranged with two flat parts on the retaining ring 505. The bottom of the base 501 is rotatably connected to the turntable 506. This design not only limits the height of the contact wheel 504, but also allows the flat parts to be used with a wrench, making it convenient to install and remove the connecting shaft 503 and the contact wheel 504. The turntable 506 has two symmetrically arranged constraint grooves 507 inside. Each constraint groove 507 has a bearing 508 slidably connected inside. A connecting arm 509 is fixedly connected to the shaft of the bearing 508. One end of the connecting arm 509 is fixedly connected to an adjusting arm 510. By rotating the turntable 506, the bearing 508 and the connecting arm 509 can be moved in conjunction with the constraint grooves 507, thereby moving the adjusting arms 510 on both sides closer or further away, so as to adjust the distance between the four contact wheels 504.

[0038] Two connecting shafts 503 and contact wheels 504 form a group and are mounted on an adjusting arm 510. The connecting shafts 503 pass through the movable groove 502 and are fixedly connected to the adjusting arm 510. Sleeves connected to the connecting shafts 503 are provided at both ends of the adjusting arm 510, and the connecting shafts 503 and the sleeves are connected by threads, facilitating individual replacement of the connecting shafts 503 and contact wheels 504. The central shaft of the turntable 506 passes through the base 501 and is fixedly connected to a swing arm 511. The swing arm 511... A handle 512 is rotatably connected to the upper surface. A shaft 514 is inserted into the inside of the swing arm 511. Multiple holes 513 are equally spaced inside the base 501. The bottom end of the shaft 514 is inserted into the hole 513. The handle 512 can drive the swing arm 511 and the turntable 506 to rotate, thereby adjusting the distance between the contact wheels 504. The position of the swing arm 511 can be fixed by the shaft 514 and the hole 513 to ensure the stability of the position of the contact wheel 504 after adjustment.

[0039] like Figure 1 and Figure 2As shown, the positioning mechanism includes a mounting base 601 installed on the receiving rack 3. A plate 602 is fixedly connected to the bottom of the mounting base 601. Multiple slots 603 are symmetrically opened on the two side beams of the receiving rack 3, and the plate 602 is inserted into two corresponding slots 603. By inserting the plate 602 into the slot 603, the position of the mounting base 601 can be fixed. Both the plate 602 and the slot 603 are inclined, which can prevent the plate 602 from detaching from the slot 603 when the abutment plate 608 is pressed. Two side plates 604 are symmetrically fixedly connected to both sides of the mounting base 601. The bottom edges of the two side plates 604 extend to the bottom of the mounting base 601, and the two sides of the side plates 604 abut against the inner wall of the receiving rack 3. This design can prevent the mounting base 601 from moving longitudinally on the receiving rack 3 and ensure the stability of the mounting base 601 after installation.

[0040] Multiple reinforcing plates are provided between the side plate 604 and the mounting base 601 to improve the structural strength of the connection between the side plate 604 and the mounting base 601. A lead screw 605 is threadedly connected between the two side plates 604. One end of the lead screw 605 is rotatably connected to a stop plate 608, and the end of the lead screw 605 away from the stop plate 608 is fixedly connected to a handwheel 606. Two nuts 607 are threadedly connected to the outer side of the lead screw 605, and the nuts 607 abut against the side plate 604. The two side plates 604 are internally slidably connected. A sliding rod 609 is attached, one end of which is fixedly connected to the abutment plate 608. The handwheel 606 can easily drive the lead screw 605 to rotate, thereby improving the adjustment accuracy of the abutment plate 608. At the same time, with the assistance of the sliding rod 609, the abutment plate 608 can be prevented from deflecting, thus ensuring frontal contact with the steel profile. The nut 607 set on the lead screw 605 abuts against the side plate 604, which can withstand the impact force of the steel profile on the abutment plate 608 and reduce the possibility of the lead screw 605 stripping due to the impact force.

[0041] The workflow of the technical solution provided by this utility model is as follows:

[0042] like Figures 1 to 6 As shown, when operating the steel cutting positioning device, first place the steel to be processed stably on the feeding rack 2. Then, according to the specific specifications of the steel, adjust the spacing of the contact wheels 504. Specifically, first pull out the insert shaft 514 inside the swing arm 511, and then drive the swing arm 511 to rotate through the handle 512. During the rotation of the swing arm 511, the turntable 506 will rotate synchronously. When the turntable 506 rotates, the bearing 508 inside it will move in the constraint groove 507, thereby causing the connecting arm 509 and the adjusting arm 510 to be displaced. At this time, the adjusting arm 510 pushes the connecting shaft 503 to slide in the movable groove 502, and finally achieves precise adjustment of the position of the contact wheels 504, ensuring that the spacing of the two sets of contact wheels 504 is perfectly matched with the size of the steel. After the adjustment is completed, reinsert the insert shaft 514 into the swing arm 511 and the insertion hole 513 to fix the current position.

[0043] If the contact wheel 504 wears out after long-term use, a wrench can be used to apply force to the flat part of the retaining ring 505 to remove the connecting shaft 503 from the adjusting arm 510 for replacement of the new connecting shaft 503 and contact wheel 504. After adjusting or replacing the contact wheel 504, the position of the abutment plate 608 needs to be further adjusted according to the required cutting length of the profile steel. The insert plate 602 at the bottom of the mounting base 601 is accurately inserted into the slot 603 on the receiving rack 3. Then, the screw 605 is driven to rotate by the handwheel 606. When the screw 605 rotates, it will drive the abutment plate 608 at its front end to move horizontally. During this process, the abutment plate 608 will drive the slide rod 609 to slide inside the side plate 604 to abut. The horizontal movement of plate 608 provides auxiliary support. After plate 608 moves to the appropriate position, the nut 607 on the outside of screw 605 is rotated to make it closely contact the outer wall of side plate 604, thereby effectively bearing the impact force generated by the movement of the steel section. Then, the feeding rack 2 and receiving rack 3 work together to smoothly transport the steel section onto receiving rack 3. During the movement of the steel section, it is effectively clamped and limited by multiple contact wheels 504, which also play a guiding and auxiliary role. When the front end of the steel section contacts plate 608, the transport is stopped immediately. At this time, the sawing machine 1 is started to saw the steel section. After sawing is completed, the cut steel section is pushed off the receiving rack 3 and falls onto receiving rack 4 to complete the entire sawing process.

Furthermore, to avoid unnecessary confusion regarding the essence of this utility model, well-known methods, processes, procedures, components, and circuits are not described in detail.

[0045] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
