[0002] With the development of modern industry, slide rail profiles, as an important structural material, have been widely used in various mechanical equipment, transportation vehicles, and architectural decoration. To meet the needs of different application scenarios, slide rail profiles often need to be bent to achieve specific shapes and dimensions.

[0003] Slide profiles are structural components used for guidance, such as... Figure 1 As shown, the straight section 42 is usually much larger than the curved section 43, therefore, a mandrel 2 is often needed during the bending process to reduce the cross-sectional deformation of the slide profile 4. Figure 2 As shown, the configuration of the mandrel 2 requires the current bending equipment to not only have a long space to hold and place the slide profile 4 material, but also to have a pusher structure 8 at one end of the mandrel 2 to move and support the mandrel 2. This results in the bending equipment having a large axial dimension of the mandrel 2 and an insufficiently compact layout, which to some extent increases the manufacturing cost and transportation difficulty of the equipment.

The mandrel is mounted on the frame via the support base. The support base is movably mounted on the frame between the two ends of the mandrel, and the support base is connected to the exposed surface of the mandrel. The exposed surface is the surface of the part of the mandrel that protrudes from the slide opening of the slide profile after the mandrel is inserted into the inner cavity of the slide profile.

[0024] It should be noted that the modification of "one" or "multiple" mentioned in the utility model is illustrative and not limiting, and those skilled in the art should understand that unless otherwise explicitly stated in the context, it should be understood as "one or more".

[0025] As shown in Figure 3 and Figure 4 The utility model discloses a slide channel section bending equipment, including frame 1, core rod 2 and support seat 3, core rod 2 is set up on frame 1 through support seat 3;Support seat 3 is movably arranged between the both ends of core rod 2 on frame 1, and the exposed surface of support seat 3 is connected with core rod 2, wherein the exposed surface is the surface of the part exposed from the slide channel mouth 41 of slide channel section 4 after core rod 2 is inserted into the inner chamber of slide channel section 4.

[0026] In the above-mentioned slide channel section bending equipment, the support seat 3 is arranged on the frame 1 between the both ends of the core rod 2 by fully utilizing the structural feature that the slide channel section 4 has the slide channel mouth 41 which is different from other closed sections, and the exposed surface exposed from the slide channel mouth 41 after the core rod 2 is inserted into the slide channel section 4 is connected and supported to the core rod 2, without the need to set the support structure at one end of the extension direction of the core rod 2, thereby shortening the size of the slide channel section bending equipment in the axial direction of the core rod 2, making the space layout of the equipment more compact and reasonable, and saving the equipment space.

[0027] Optionally, the support base 3 includes a connecting rod 31, one end of which is fixed to the exposed surface, and the end of the rod extends from the exposed surface in a direction away from the main body of the core rod 2. That is, the end of the connecting rod 31 fixed to the exposed surface extends from the exposed surface in a direction away from the main body of the core rod 2.

[0028] The support base 3 supports and fixes the mandrel 2 through the connecting rod 31. The end of the connecting rod 31 extends from the exposed surface away from the main body of the mandrel 2. This is to avoid interference between the connecting rod 31 and the slide profile 4 when the mandrel 2 moves relative to the slide profile 4, thus ensuring the normal operation of the slide profile 4 bending device.

[0029] Optionally, the support base 3 also includes a base plate 32 and a first drive mechanism 33. A connecting rod 31 is provided on the base plate 32. The base plate 32 is movably mounted on the frame 1. The first drive mechanism 33 is used to drive the base plate 32 to move along the axial direction of the mandrel 2.

[0030] The mobility of the base plate 32 and the driving action of the first driving mechanism 33 enable the support seat 3 to move along the axial direction of the mandrel 2, thereby driving the connecting rod 31 and the mandrel 2 to move. Thus, during the bending process of the slide profile 4, the mandrel 2 can be stably supported and moved and adjusted, ensuring that the mandrel 2 can be smoothly inserted into the predetermined position in the inner cavity of the slide profile 4.

[0031] Specifically, the base plate 32 can be movably connected to the frame 1 in various ways, such as via slide rails, rollers, or other guiding mechanisms. Optionally, the frame 1 is provided with a first guide rail 11, which is arranged along the axial direction of the mandrel 2, and the base plate 32 is slidably mounted on the first guide rail 11. Figure 3 As shown, the first guide rail 11 is mounted on the frame 1, and the base plate 32 is slidably connected to the first guide rail 11 via a slider, thereby enabling movement along the axial direction of the mandrel 2.

[0032] Alternatively, the first drive mechanism 33 can use an electric motor, hydraulic cylinder, or other drive device to drive the base plate 32. For example, Figure 3 As shown, the first drive mechanism 33 uses an electric push rod, which drives the base plate 32 to move axially along the mandrel 2 through the extension and retraction of the electric push rod. Of course, the first drive mechanism 33 can also use a servo motor with a lead screw, a servo motor with a synchronous belt, or a servo motor with a gear and rack to drive the base plate 32.

[0033] Optionally, the connecting rod 31 is located on one side of the core rod 2.

[0034] The connecting rod 31 is arranged on one side of the mandrel 2 to support the mandrel 2 from the side, and the exposed surface of the corresponding mandrel 2 faces the side where the connecting rod 31 is located, and the sliding channel profile 4 also faces the side where the connecting rod 31 is located after being clamped on the equipment; this design can ensure that the relative movement between the mandrel 2 and the sliding channel profile 4 during the bending process of the sliding channel profile 4 is not disturbed, ensuring the smooth progress of the bending process.

[0035] Specifically, the connecting rod 31 can be fixed on one side of the mandrel 2 by welding, bolting or other methods to ensure that it does not loosen or fall off during use. The material of the connecting rod 31 can be high-strength alloy steel or other materials with good mechanical properties to improve its durability and load capacity. The shape and size of the connecting rod 31 can be adjusted according to actual needs to adapt to different mandrel 2 arrangement postures. As a preferred embodiment, the connecting rod 31 can be L-shaped, with one end fixed on the exposed surface and the other end fixed on the bottom plate 32, which is simple in structure and stable and reliable in connection.

[0036] Optionally, the connecting rod 31 is spaced apart along the axial direction of the mandrel 2.

[0037] By spacing multiple connecting rods 31, support can be provided at different positions of the mandrel 2, so that the rod body of the mandrel 2 remains flat and straight, avoiding deformation and warping of the mandrel 2 during use. Specifically, the number and spacing of the connecting rods 31 can be adjusted according to the length of the mandrel 2 and the size of the sliding channel profile 4 to achieve the best support and connection effect.

[0038] Further, the connecting part of the support seat 3 and the exposed surface is located in the middle of the mandrel 2.

[0039] The mandrel 2 moving mechanism of the existing bending equipment is usually designed at one end of the mandrel 2. Since a long mandrel 2 is required during the bending process of the sliding channel profile 4, this single-end support design is prone to cause deformation and warping of the mandrel 2 during long-term use, which not only affects the machining precision, but also shortens the service life of the equipment and increases the maintenance cost.

[0040] The connecting part of the support seat 3 and the exposed surface of the present application is located in the middle of the mandrel 2, i.e. the connecting end of the connecting rod 31 and the mandrel 2 is located in the middle of the mandrel 2. Middle support can ensure that the mandrel 2 maintains the correct position and posture during the machining process, optimizes the stress distribution of the mandrel 2, improves the load capacity and service life of the mandrel 2, and also helps to improve the machining precision and product quality.

[0041] Further, the cross section of the mandrel 2 is the same as the inner cavity cross section of the slide rail profile 4, the mandrel 2 is designed according to the inner cavity cross section of the slide rail profile 4, and can be filled in the inner cavity of the slide rail profile 4. During bending, the end of the mandrel 2 extends to the bending start point of the slide rail profile 4, reducing cross section deformation. The exposed surface is located on one side of the axis of the mandrel 2 to achieve horizontal bending, and can be arranged on any side. In addition, compared with arranging the exposed surface at the bottom or top of the axis, arranging the exposed surface on the side facilitates the arrangement of the connecting structure on the support seat 3, that is, the arrangement of the connecting rod 31, reduces motion interference, and facilitates manual placement of the slide rail profile 4 during feeding.

[0042] Further, as shown in Figure 3 The slide rail bending equipment also includes a pushing assembly 5, a die guiding assembly 6 and a bending assembly 7 arranged on the rack 1. The pushing assembly 5 and the die guiding assembly 6 are used to clamp and move the slide rail profile 4. The bending assembly 7 is used to bend the slide rail profile 4. Clamping and bending the slide rail profile 4 are basic structural functions of the slide rail bending equipment, and the clamping and bending structure principle is the same as that of the existing bending equipment.

[0043] In this embodiment, the cross section of the slide rail profile 4 is in the shape of a U. The pushing assembly 5 and the die guiding assembly 6 clamp the slide rail profile 4 at the two ends of the straight section 42, respectively. The clamping positions are both the two side plates of the U-shaped slide rail profile 4. After clamping, the axis of the slide rail profile 4 is horizontal, and the cross section in the vertical direction is as shown in Figure 4 The pushing assembly 5 clamps one end of the slide rail profile 4 through the chuck 51, and moves and adjusts the position of the chuck 51 through the driving motor 52, the gear, the sliding plate 53 and the rack 54. Therefore, it can be applied to slide rail profiles 4 of different specifications and sizes, and can also move and adjust the slide rail profile 4 during bending. The die guiding assembly 6 is arranged near the bending assembly 7. During bending, the end connecting the straight section 42 and the bending section 43 is fixed to realize the fixation of the entire straight section 42. The bending assembly 7 drives the slide rail profile 4 to bend along the contour of the bending die through the swing arm mechanism.

[0044] In addition, the sliding plate 53 is slidably arranged on the rack 1, and the rack 54 is fixed on the rack 1. Specifically, the sliding plate 53 can be slidably arranged on the rack 1 through the first guide rail 11. Since the size of the straight section 42 of the slide rail profile 4 is generally long, the sliding plate 53 does not interfere with the bottom plate 32.

[0045] In use, first, feeding: the slide profile 4 material is sleeved on the mandrel 2, and is clamped, specifically, the chuck 51 of the feeding assembly 5 clamps the non-bent end of the mandrel 2, and the die assembly 6 is clamped on the linear section 42 at the position where the bent section 43 meets; then, the end of the slide profile 4 is bent, specifically, the bending assembly 7 is started, and the bent section 43 is rotated by a set angle in the horizontal direction, namely, the bending processing is completed; finally, discharging. It should be noted that when the same kind of slide profile 4 is produced, the position of the mandrel 2 of the slide profile bending equipment is the same, and is set when the machine is adjusted, and remains unchanged in the production process, namely, only when the specification of the slide profile 4 to be processed changes, the mandrel 2 is adjusted and moved.

[0046] Although the utility model discloses as above, the protection scope of the utility model is not limited to this only.The person skilled in the art can make various changes and modifications without departing from the spirit and scope of the utility model, and these changes and modifications will all fall into the protection scope of the utility model.
