An angle steel opening and closing machine

Abstract

This utility model relates to the technical field of angle steel opening and closing machines. It provides an angle steel opening and closing machine, including a machine tool with an angle-closing station. The angle-closing station has a first plate and a second plate forming a channel for guiding the angle steel. The side of the second plate away from the first plate is a pressing groove for accommodating the pressed portion of the angle steel's b-side. A first rotating wheel is rotatably mounted on the machine tool to guide the b-side of the angle steel to the top of the pressing groove. A pressing component is lifted and lowered on the machine tool to press the portion of the angle steel's b-side above the pressing groove into the groove. When pushing the angle steel, the first rotating wheel uses rolling friction instead of sliding friction, reducing pushing resistance and making the angle steel move more smoothly. The first rotating wheel guides the angle steel upwards towards the pressing groove, ensuring that it effectively supports the side of the angle steel, guaranteeing support stability, extending the service life of the first rotating wheel, and reducing equipment maintenance costs.

Description

Technical Field

[0001] The embodiments of this utility model relate to the technical field of angle steel opening and closing machines, specifically, to an angle steel opening and closing machine. Background Technology

[0002] In traditional angle steel cutting technology, the movement of angle steel mainly relies on manual pushing or simple sliding rails. During the movement towards the cutting part, significant sliding friction is generated. Especially for large and heavy angle steel, workers need to expend considerable physical strength to push it, which is not only inefficient but also makes it difficult to ensure the stability of the angle steel during the pushing process, easily leading to deviation, inaccurate positioning, and consequently affecting the cutting accuracy. Furthermore, prolonged sliding friction leaves obvious scratches on the angle steel surface, damaging the workpiece surface quality and increasing the scrap rate; it also accelerates the wear of the workstation support surface, shortens the equipment's lifespan, and increases maintenance costs.

A pressing component is provided on the machine tool and has a first pressing part located above the pressing groove. The pressing component is used to press the portion of the angle steel with side b located above the pressing groove into the pressing groove.

[0005] For example, in at least one embodiment of the present invention, an angle steel opening and closing machine further includes: a second rotating wheel, which is rotatably disposed on the machine tool and located at both ends of the pressing groove along the x direction, respectively, and the second rotating wheel is used to roll and abut against the b side of the angle steel after the angle is closed.

[0006] For example, in at least one embodiment of the present invention, an angle steel opening and closing machine is provided, wherein the lifting assembly is located on the side of the first rotating wheel away from the pressing groove, and includes: A lifting component, which is lifted and lowered on the machine tool; The top wheel is rotatably mounted on the lifting component. The b-side of the angle steel is used for rolling contact, which can raise and lift the b-side of the angle steel. A first linear drive unit is disposed on the machine tool and is used to drive the lifting unit to move up and down.

[0007] For example, in an angle steel opening and closing machine provided in at least one embodiment of the present invention, the lifting assembly has two sets, and the other set of the lifting assembly is located on the side of the second rotating wheel away from the pressing groove.

[0008] For example, in an angle steel opening and closing machine provided in at least one embodiment of the present invention, the second plate has a support portion located in the pressing groove, the support portion has an inclined surface extending downward in a direction away from the second plate.

[0009] For example, in at least one embodiment of the present invention, an angle steel opening and closing machine is provided, wherein the machine tool further has an opening angle station, the opening angle station being located on one side of the closing angle station, and further includes: An angle bracket, wherein the angle bracket has two arc-shaped portions, the two arc-shaped portions being used to support side a and side b of the angle steel, respectively. The pressing component also has a second pressing part, which is located above the arc-shaped part and is used to push the angle steel from top to bottom to open the angle.

[0010] For example, in at least one embodiment of the present invention, an angle steel opening and closing machine further includes: a first support wheel, which is rotatably disposed in the opening station and is used to roll against the a side and b side of the angle steel to guide the angle steel onto the opening member.

[0011] For example, in at least one embodiment of the present invention, an angle steel opening and closing machine further includes: a second support wheel, which is rotatably disposed in the opening station and is used to roll against the a side and b side of the angle steel.

[0024] like Figures 1-4As shown, this invention relates to an angle steel 1 opening and closing machine. The machine tool 2 has an angle closing station 201 and an angle opening station 202, which are integrated into one unit. The angle closing station 201 is provided with a first plate 3 and a second plate 4, which are arranged at intervals to form a channel 5 parallel to the x-direction. Here, the x-direction is defined as the length direction of the first plate 3, which is also the direction of movement of the angle steel 1 in the angle closing station 201. For ease of understanding, the angle steel 1 is defined as side a and side b. During processing, side a of the angle steel 1 is first placed into the channel 5, making side a vertical and side b horizontal. Preferably, the distance between the first plate 3 and the second plate 4 is designed to be slightly larger than the width of side a of the angle steel 1, which facilitates the placement of side a into the channel 5 and also forms a constraint through the gap to prevent side a from shaking. The side of the second plate 4 away from the first plate 3 is provided with a pressing groove 6 to accommodate the deformed part of side b after pressing.

[0025] The first rotating wheel 7 is rotatably mounted on the machine tool 2. When side a of the angle steel 1 is placed into the channel 5, side b naturally rests on the first rotating wheel 7. When pushing the angle steel 1, the first rotating wheel 7 uses rolling friction instead of sliding friction to reduce the pushing resistance and make the angle steel 1 move more smoothly. At the same time, the rotation direction of the first rotating wheel 7 guides side b to move upward towards the pressing groove 6, so that side b moves to the bottom of the pressing part 8.

[0026] The height of the second plate 4 is flush with or slightly lower than the upper end of the first roller 7, ensuring that the first roller 7 can effectively support side b. Preferably, the height of the second plate 4 is flush with the upper end of the first roller 7, allowing the second plate 4 to share some of the pressure and preventing the first roller 7 from deforming under long-term stress. This ensures support stability, extends the service life of the first roller 7, and reduces equipment maintenance costs.

[0027] like Figures 2-3 As shown, the pressing component 8 is mounted on the machine tool 2 via a lifting mechanism, with its first pressing part 801 facing directly above the pressing groove 6. When side b moves above the pressing groove 6, the pressing component 8 moves downward, and the first pressing part 801 presses side b into the pressing groove 6, completing the angle engagement operation. Even if the angle between side a and side b decreases, the lifting action of the pressing component 8 can be achieved by hydraulic, pneumatic, or electric drive, ensuring uniform and controllable pressure. In this scheme, the first pressing part 801, as shown in the figure, has an inclined pressing part, which is used to push side b of the angle steel 1, ensuring that side b is subjected to uniform force and accurate forming angle during downward pressing.

[0028] In some examples, the second roller 9 and the first roller 7 are respectively arranged at both ends of the pressing groove 6 along the x-direction (i.e., the direction of movement of the angle steel 1), forming a supporting rolling guide for both ends of the b side of the angle steel 1. When the angle steel 1 moves along the channel 5, the b side first contacts the first roller 7 and is guided to the top of the pressing groove 6 through rolling friction. After being pressed down by the pressure member 8, the angle is closed. At this time, the angle between the a side and the b side becomes smaller, and the angle steel 1 continues to move to the other end. In order to support the b side whose position changes after the angle is closed, the height of the second roller 9 can be set to be lower than the height of the first roller 7, that is, the upper end of the second roller 9 is lower than the upper end of the first roller 7. The rotation axis of the second roller 9 can be set to have a certain slope to adapt to the b side after the angle is closed, or it can be kept horizontal, which is not limited here. The b side then contacts the lower-height second roller 9, which receives and continuously guides the b side, ensuring that the b side maintains a stable rolling state throughout the movement and avoiding deviation or jamming due to lack of support.

[0029] like Figures 2-4 As shown, in some examples, the lifting assembly 10 mainly solves the problem of the angle steel 1 easily getting stuck on the second plate 4 after pressing. One set of lifting assemblies 10 is located on the side of the first rotating wheel 7 away from the pressing groove 6, and the other set of lifting assemblies 10 is located on the side of the second rotating wheel 9 away from the pressing groove 6. After the b-side of the angle steel 1 is pressed into the pressing groove 6 by the pressing member 8 to complete the angle engagement, the first linear drive member 1003 drives the lifting member 1001 to rise, driving the top wheel 1002 to rise synchronously. The top wheel 1002 rolls and abuts against the b-side of the angle steel 1, lifting the angle steel 1 as a whole upward, so that it is disengaged from the second plate 4, eliminating the jamming force generated by pressing. At this time, the angle steel 1 is lifted to a certain height, and the worker can easily push the angle steel 1 to continue moving or remove the workpiece. Since the height of the two sets of lifting components 10 top wheels 1002 is matched with the corresponding rotating wheels (the top wheel 1002 closer to the first rotating wheel 7 is at the same height as the first rotating wheel 7, and the top wheel 1002 closer to the second rotating wheel 9 is at the same height as the second rotating wheel 9), it ensures that the angle steel 1 remains stable during the lifting process and will not tilt due to the height difference.

[0030] The top wheel 1002 can be made of wear-resistant materials, such as hard alloy or high-strength rubber-coated metal wheel body, with anti-slip textured surface to enhance friction with the angle steel 1b and prevent slippage during lifting. The top wheel 1002 is mounted on the lifting component 1001 via bearings to ensure flexible rotation. The first linear drive component 1003 can be driven by a hydraulic cylinder, pneumatic cylinder, or electric actuator.

[0031] The lifting assembly 10 effectively eliminates the jamming phenomenon of angle steel 1 after pressing, preventing workpiece deformation or equipment damage caused by workers forcibly pulling angle steel 1, thus reducing scrap rate and equipment maintenance costs. After the top roller 1002 lifts angle steel 1, the workpiece separates from the second plate 4, allowing workers to easily push angle steel 1 to continue processing or remove the finished product, significantly reducing labor intensity and improving processing efficiency. The two sets of lifting assemblies 10 are height-matched with the rotating rollers, ensuring that angle steel 1 remains horizontal and stable during lifting and movement, preventing angle deviation caused by tilting, and ensuring the accuracy and consistency of subsequent pressing processes.

[0032] In some examples, when the pressing member 8 presses edge b into the pressing groove 6, edge b deforms under pressure and approaches the inclined surface 402 of the support part 401. The inclined surface 402 extends outward and downward from the second plate 4, providing support for the bent edge b and preventing edge b from twisting or springing due to uneven force. The guiding characteristics of the inclined surface 402 ensure that edge b remains stable after pressing, while also assisting it in forming along a preset angle, improving the accuracy and quality of the joint angle. The inclination angle of the inclined surface 402 can be determined according to the actual situation; it is only shown in this figure and is not limited here.

[0033] In some examples, the angle opening station 202 and the angle closing station 201 are arranged in conjunction. During operation, the a-side and b-side of the angle steel 1 are placed on the two arc-shaped portions 1101 of the angle opening component 11, respectively. The arc-shaped portions 1101 conform to the two sides of the angle steel 1 through their curved surfaces, forming a stable support. Subsequently, the second pressing portion 802 of the pressing component 8 presses down vertically from above, forcing the a-side and b-side of the angle steel 1 to deform under the constraint of the arc-shaped portions 1101, causing the included angle to gradually increase, thus completing the angle opening operation. The arc-shaped portions 1101, through the guiding effect of their curved surfaces, prevent the angle steel 1 from shifting or twisting under pressure, ensuring the accuracy of the angle opening angle. The two arc-shaped portions 1101 adopt a split or integrated structure, with the curvature of the curved surface matching the cross-sectional contour of the angle steel 1, ensuring that the a-side and b-side are tightly fitted and preventing slippage. The second pressing portion 802 is connected to the pressing component 8 by bolts or integrally formed, and its bottom surface can be flat. The opening and closing angle stations 201 are integrated into the same machine tool 2, allowing both processes to be completed without changing equipment, reducing workpiece transfer time and manual operation steps, and improving production efficiency. The dual-function design of the pressing part 8 (the first pressing part 801 is used for closing angles, and the second pressing part 802 is used for opening angles) simplifies the structure of the machine tool 2 and reduces equipment costs; at the same time, the shared drive system further enhances the integration and automation level of the equipment.

[0034] The first support wheel 12 is arranged on one side of the corner piece 11 and rolls against the a and b sides of the angle steel 1 through two inclined parts 14 to form a guide slope. When the angle steel 1 enters the corner opening station 202, the a and b sides move along the inclined parts 14 to the two arc-shaped parts 1101 of the corner piece 11, and the rolling friction reduces the pushing resistance. At the same time, the angle design of the inclined parts 14 ensures that the angle steel 1 is positioned in the corner piece 11.

[0035] The second support wheel 13 is located on the other side of the corner opening piece 11. It also rolls against both sides of the angle steel 1 through the inclined part 14. After the corner is opened, the angle steel 1 is led out through the second support wheel 13. Preferably, the inclined part 14 matches the included angle of the a and b sides of the angle steel 1 (e.g., 45° inclination). The first support wheel 12 is close to the feeding end, and the second support wheel 13 is close to the unloading end. Both of them maintain an appropriate distance from the corner opening piece 11 (e.g., 5-10cm) to ensure that the angle steel 1 has a smooth path when it is introduced and exported.

[0036] In some examples, the pressing component 8 spans the opening angle station 202 and the closing angle station 201. The pressing component 8 is moved by the second linear drive component 15, which can synchronously drive the first pressing part 801 and the second pressing part 802 to rise and fall. Preferably, there are two second linear drive components 15, which drive the two ends of the pressing component 8 respectively. Hydraulic drive components can be selected. The closing angle station 201 and the opening angle station 202 can both be used to place the angle steel 1 for synchronous processing, or they can be used separately, which improves the convenience of processing.
