[0002] Currently, the production of W-shaped, load-bearing, quick-install supports and hangers in the construction hardware industry typically relies on multiple independent machines to perform the extrusion, bending, and shearing processes, resulting in low production efficiency, large positioning errors, and poor mold adaptability. Traditional equipment often uses fixed-angle molds, making it difficult to meet the diverse needs of complex working conditions. Furthermore, existing equipment has a low level of automation, requiring manual handling of supports and hangers, and preventing parametric control and quality traceability. Therefore, a new type of processing equipment is urgently needed. Summary of the Invention

[0031] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present application.

[0032] As Figures 1 - 5 shown, the processing equipment according to the embodiment of the present application is used for processing the W-shaped load-bearing quick-install support hanger 30, and includes: a forming module, a bending module 10, a shearing module 20, and a control module.

[0033] Specifically, the forming module includes a first fixed mold, a first movable mold and a first drive assembly. When the first movable mold moves to cooperate with the first fixed mold, they jointly define a W-shaped extrusion groove; the bending module 10 includes a second fixed mold 11, a rotating mold 12 and a second drive assembly. The rotating mold 12 rotates between a first position and a second position. When the rotating mold 12 is in the first position, it jointly defines a straight groove with the second fixed mold 11. When the rotating mold 12 is in the second position, it jointly defines a curved groove with the second fixed mold 11. The second drive assembly is connected to the rotating mold 12 to drive the rotating mold 12 to rotate; the shearing module 20 includes a second fixed mold 11, a second movable mold 22 and a third drive assembly. When the second movable mold moves to cooperate with the second fixed mold 11, they jointly define a W-shaped shearing edge. The third drive assembly is connected to the second movable mold 22 to drive the second movable mold 22 to move; the first drive assembly, the second drive assembly and the third drive assembly are all electrically connected to the control module.

[0034] It can be understood that the forming module, the bending module 10 and the shearing module 20 are three workstations arranged in sequence, and the profile passes through the forming module, the bending module 10 and the shearing module 20 in sequence.

[0035] In a specific embodiment, the working surface of the first fixed mold is in an inverted W-shape, the first drive assembly is a hydraulic drive assembly, the profile is pushed into the W-shaped extrusion groove by the feed roller, and the first drive assembly drives the first movable mold to move downward. The working surface of the first movable mold is also in an inverted W-shape. The working surface of the first movable mold contacts the profile, so that the profile is plastically deformed into a W-shaped cross-section under pressure.

[0036] In a specific embodiment, a plurality of elastic support blocks are provided in the W-shaped extrusion groove. The elastic support blocks are provided on the first fixed mold or the first movable mold. The elastic support blocks should be distributed at the key contact points of the extrusion groove, such as the crests and troughs of the W-shape. The elastic support blocks need to have sufficient elasticity and wear resistance to withstand repeated extrusion and friction. Commonly used materials may include rubber, polyurethane or silicone. The elastic support blocks are used to buffer the punching force of the first movable mold, provide uniform support force, and prevent deformation of the profile.

[0037] In a specific embodiment, the second fixed mold 11 of the bending mold is vertically fixed and sideways in a W-shape. The second drive assembly includes a servo motor and a planetary gear reducer that are sequentially connected in a transmission manner. The output shaft of the planetary gear reducer is connected in a transmission manner to the rotating mold 12 to drive the rotating mold 12 to rotate. The first parting mold 13 and the second parting mold rotate synchronously. When the rotating mold 12 is in the first position, the rotating mold 12 rotates through 0° to form a linear groove with the second fixed mold 11 for the profile to enter the bending mold. After the profile is in place, the rotating mold 12 can be rotated to any desired angle (less than or equal to 180°), for example, 30°, 40°, 50°, 60°, 70°, 80°, 90°, 100°, 110°, 120°, 130°, and 140°. For example, when the rotating mold 12 is in the second position, it and the second fixed mold 11 jointly define an L-shaped groove.

[0038] like Figure 5 As shown, in one specific embodiment, the second fixed die 11 and the second movable die 22 of the shearing module 20 form a W-shaped cutting edge when closed. A third drive assembly, comprising a servo motor and a ball screw assembly connected in series, drives the second movable die 22 downward. During shearing, the wedge-shaped structure of the cutting edge cuts into the profile, and the front and rear angles are designed to evenly distribute the shearing force, resulting in a smooth, burr-free cut.

[0039] In one specific embodiment, the control module utilizes a PLC controller to control the timing of the first, second, and third drive assemblies. Pressure sensors monitor the pressure in each cylinder, while displacement sensors provide feedback on the positions of the first and second movable dies 22 and the rotary die 12. The control module dynamically adjusts drive speed and pressure based on preset parameters, achieving automated control of the entire process, from profile feeding, extrusion molding, angle bending, to precise shearing.

[0040] According to the processing equipment of the embodiment of the present application, the first movable mold moves toward or away from the first fixed mold, so that the material can be processed and demolded. The forming module cooperates with the first fixed mold and the first movable mold to form a W-shaped extrusion groove, so that the incoming plate material can be processed to plastically deform the material to form a stable cross-sectional structure, thereby improving the bending strength of the support bracket 30 and adapting to profiles of different thicknesses; the rotating mold 12 of the bending module 10 can control the rotation adjustment angle as needed to achieve straight on-demand multi-angle bending and adapt to various processing requirements; the W-shaped blade edge of the shearing module 20 matches the profile cross-section, and cooperates with the high-precision drive system to achieve a smooth incision; the control module links the forming module, the bending module 10 and the shearing module 20 to complete the full-process timing control, thereby improving the integration of the processing process, the high adaptability of the mold, and improving the production efficiency and the qualified rate of finished products.

[0041] like Figure 1 、Figures 3 - 5 As shown in the figure, for the processing equipment according to an embodiment of the present application, the W-shaped load-bearing quick-install support hanger 30 includes a first surface A and a second surface B that are oppositely arranged in the thickness direction. A convex platform 31 is provided on the first surface A, and concave portions 32 are symmetrically arranged on both sides of the convex platform 31. The rotary die 12 is arranged on the first base. The rotary die 12 includes a first split die 13 and a second split die that are arranged at intervals. The first split die 13 includes a chassis 14 and an arc-shaped end portion arranged on the chassis 14. The chassis 14 is rotatably connected to the first base. Two spaced first protrusions 131 are provided on the arc-shaped end portion. The lower first protrusion 131 is spaced from the chassis 14. The first protrusion 131 is used to be stuck on both sides of the convex platform 31. The first protrusion 131 extends along the outer surface of the arc-shaped end portion to form a U shape.

[0042] The W-shaped load-bearing quick-install support hanger 30 is divided into a first surface A and a second surface B in the thickness direction. The concave portions 32 symmetrically arranged on both sides of the convex platform 31 are trapezoidal grooves, which effectively reduce the weight while ensuring the structural strength, and form a stress relief area through the groove structure to avoid concentrated deformation of materials. The rotary die 12 is installed on the first base and is composed of a first split die 13 and a second split die arranged at intervals, and the two realize parallel movement. The arc-shaped end portion of the first split die 13 is convenient for bending the profile without causing stress concentration. Two first protrusions 131 provided thereon form a wedge-shaped fit with the vertical surfaces on both sides of the convex platform 31, and the two first protrusions 131 constitute a clamping structure for the convex platform 31. When the profile enters the die, the first protrusions 131 are stuck on both sides of the convex platform 31 to ensure that the profile maintains an accurate posture without slipping during the bending process. The curved surface design of the arc-shaped end portion makes the extrusion force distributed in a sine wave along the cross-section of the profile, reducing the stress concentration area compared with the traditional right-angle die. This structural design significantly improves the load-bearing capacity of the support hanger 30, eliminates the need for manual correction during the production process, evenly wears the die, and extends the service life. The chassis 14 serves as a basic support structure, providing rigid support for the arc-shaped end portion and the first protrusions 131. The integrated molding process of the chassis 14 and the arc-shaped end portion reduces the assembly error, improves the overall rigidity of the die, reduces the vibration conduction, and evenly distributes the bending force to the cross-section of the profile; the wear-resistant coating (such as TiN coating) provided on the bottom surface of the chassis 14 forms a low-friction pair with the contact surface of the first base, reducing the friction coefficient to less than 0.08, significantly reducing the rotational resistance and extending the service life of the die.

[0043] As Figures 2 - 4 shown in the figure, in some embodiments, a second protrusion 132 is arranged between the two first protrusions 131. Along the radial direction of the first split die 13, the protruding height of the second protrusion 132 is less than the protruding height of the first protrusion 131. The second protrusion 132 is used to abut against the convex platform 31.

[0044] In the above embodiments, two first protruding portions 131 are symmetrically distributed on both sides of the boss 31 to form a clamping structure. The height of the second protruding portion 132 provided therebetween is lower than that of the first protruding portion 131. The first protruding portion 131 clamps both sides of the boss 31, and the second protruding portion 132 presses against the top surface of the boss 31 to form a triangular stable support system, ensuring that there is no lateral displacement and rotational deviation of the profile during the bending process. By reducing the height of the second protruding portion 132, a gradient stress distribution is formed, avoiding depression or cracking of the top surface of the boss 31 due to local stress concentration, significantly improving the bending stability, reducing the material loss rate, and at the same time prolonging the die life through stress optimization.

[0045] In some embodiments, along the axial direction of the first split die 13, first guiding inclined surfaces 1311 are provided on both opposite sides of the first protruding portion 131. The distance between the ends of the two first guiding inclined surfaces 1311 away from the first split die 13 is smaller than the distance between the ends of the two first guiding inclined surfaces 1311 close to the first split die 13.

[0046] During the profile processing, the first guiding inclined surface 1311 can guide the boss 31 of the profile to be accurately aligned, reducing manual calibration and making it easy for the first protruding portion 131 to be inserted into the concave portion 32. The tapered structure enables the clamping force to be evenly distributed, avoiding material deformation caused by stress concentration and wear of the first split die 13. Moreover, due to the existence of the first guiding inclined surface 1311, a self-centering effect is generated during bending, ensuring the stable attitude of the profile and reducing the stress concentration area. At the same time, during the demolding stage, the first guiding inclined surface 1311 can play an auxiliary role, making the demolding process easier and avoiding difficult demolding or damage to the profile due to excessive friction or structural interference. It should be noted that the first split die 13 includes opposite ends, one end is close to the first base, and the other end is far from the first base. The direction between these two ends is the axial direction of the first split die 13, that is, the axial direction of the first split die 13 is perpendicular to the first base.

[0047] As Figure 3 and Figure 4 shown, in some embodiments, the cross-sectional shape of the second protruding portion 132 is semi-circular arc-shaped. The length of the second protruding portion 132 extending circumferentially along the arc-shaped end is L, and the length of the first protruding portion 131 extending circumferentially along the arc-shaped end is L1, where 1 / 3L1 ≤ L ≤ 3 / 4L1.

[0048] In the above-described embodiment, the semicircular arc's apex contacts the boss 31, allowing the second protrusion 132 to form line contact with the boss 31. This precisely transmits pressure to a specific location on the boss 31, avoiding the stress dispersion caused by large-area contact and concentrating pressure at key locations, effectively improving the control accuracy of the profile during the bending process. This line contact approach also reduces the friction area with the boss 31 surface, lowering the risk of scratches on the profile surface. It also allows the profile to more flexibly undergo plastic deformation during bending, reducing stress concentration within the material. The proportional relationship between its length and that of the first protrusion 131 ensures that the second protrusion 132 provides stable support on the top surface of the boss 31, assisting the first protrusion 131 in securing the profile and preventing it from shifting or shaking during the bending process, while also ensuring that its excessive length does not affect the grip of the first protrusion 131, thus ensuring the balance and stability of the overall structure. During the bending process, the line contact combined with the arc shape guides the material to flow more smoothly along the mold contour, avoiding material accumulation and the formation of flash. In addition, it can also assist the profile to maintain a precise posture, so that the boss 31 is evenly stressed, avoiding structural failure due to local overload, while reducing the contact friction between the mold and the profile, extending the service life of the mold, and improving the demolding smoothness, ultimately significantly improving the molding quality and production efficiency of the support bracket 30.

[0049] Among them, L can be 1 / 3L1, 5 / 12L1, 6 / 12L1, 7 / 12L1, 8 / 12L1 and 3 / 4L1, etc.

[0050] like Figure 1 and Figure 2 As shown, in some embodiments, the second parting mold includes a mating surface opposite to the first parting mold 13, and the mating surface has a third protrusion that is adapted to the contour of the inner recess 32 on the second surface B. The third protrusion is linear. When the first parting mold 13 and the second parting mold are mated, the third protrusion is located on the outside of the first protrusion 131.

[0051] In the above-described embodiment, the third protrusion matches the contour of the inner recess 32, precisely positioning the profile and ensuring it is correctly positioned between the first and second sub-molds 13, thereby ensuring processing accuracy. During the bending process, the third protrusion provides additional support for the profile, working in conjunction with the first and second protrusions 131, 132 of the first sub-mold 13 to ensure more uniform force distribution. Located outside the first protrusion 131, it strengthens the constraint on the profile edge, preventing deformation and wrinkling during bending, thereby improving bending quality. Furthermore, the linear third protrusion, when mated with the inner recess 32, more stably transmits pressure, ensuring effective force application and making the bending process more stable and reliable. It also reduces the profile's rebound during bending, as the outer third protrusion can, to a certain extent, offset the internal rebound stress of the material, ensuring that the resulting bend angle more closely meets design requirements. At the same time, this structural design makes the mold more adaptable to profiles of different sizes and specifications. As long as the contours of the inner recess 32 are similar, good fit and processing can be achieved, thereby improving the versatility of the mold and the processing range of the equipment.

[0052] In a specific embodiment, a second guiding slope is provided on a side of the third protrusion close to the first protrusion 131 , and the second guiding slope is provided toward the top surface of the second parting mold in a direction gradually approaching the first parting mold 13 .

[0053] In some embodiments, the processing equipment also includes a fourth drive component, which is arranged on the first base. The fourth drive component is connected to the second parting mold to drive the second parting mold to approach the first parting mold 13 or away from the first parting mold 13. The fourth drive component includes a power part, a screw rod and a nut sleeved on the screw rod, the nut is connected to the second parting mold, and limiting devices are provided at both ends of the screw rod. The limiting device is arranged on the first base. The limiting device includes a limiting block and a buffer pad. The buffer pad is arranged on the side of the limiting block close to the nut.

[0054] In the above-mentioned embodiment, the power unit converts the rotational motion into the linear motion of the second parting mold through the screw-nut pair, realizing precise displacement control of driving the second parting mold toward or away from the first parting mold 13, thereby adjusting the gap between the first parting mold 13 and the second parting mold to adapt to the thickness of different profiles. The limit devices at both ends of the screw provide double protection when the nut moves to the end point of the stroke through a combination of a limit block and a buffer pad. The limit block is made of wear-resistant metal material, and when it contacts the end face of the nut, it directly limits its range of movement to prevent overtravel and mold collision damage; the buffer pad is made of highly elastic rubber and is arranged between the limit block and the nut. It can absorb impact energy, reduce vibration and noise caused by rigid collision, and protect the screw thread from instantaneous overload damage. The power unit is driven by a servo motor, combined with the high-precision pitch design of the screw, so that the position control accuracy of the second parting mold reaches the micron level, meeting the processing requirements of different profile thicknesses and bending angles.

[0055] As shown Figure 5 in the figure, the processing equipment according to the embodiment of the present application, the third fixed die 21 includes a second base and a lower support member 211 disposed on the second base. The number of the lower support members 211 is two, and the two lower support members 211 are arranged side by side at intervals. The lower support member 211 includes a first jacking portion and first groove portions 2112 respectively disposed on both sides of the first jacking portion. The first jacking portion is adapted to the contour of the boss 31 on the second surface B, and the first groove portions 2112 are adapted to the contour of the concave portion 32 on the second surface B. The cutting edge of the second moving die 22 includes two second jacking portions 221 and a second groove portion 222 disposed between the two second jacking portions 221. The second jacking portion 221 is adapted to the contour of the first surface A of the concave portion 32.

[0056] In the above embodiment, the first jacking portion of each lower support member 211 is adapted to the contour of the boss 31 on the bottom surface of the profile, and the two first groove portions 2112 on both sides form a fit with the contour of the concave portion 32. When the profile enters the shearing station, the lower support member 211 forms a support on the bottom surface of the boss 31 through the combined structure of the first jacking portion and the first groove portions 2112. At the same time, the outside of the concave portion 32 is accurately positioned by the first groove portions 2112, ensuring that the profile has no displacement and warping during the shearing process. The two second jacking portions 221 are in contact with the top surface contour of the concave portion 32, and the middle second groove portion 222 corresponds to the position of the boss 31. During shearing, when the cutting edge moves downward, the second jacking portion 221 contacts the top surface of the concave portion 32, and the shearing force is evenly transmitted to the cross-section of the profile through the curved surface guidance. The middle second groove portion 222 forms a stress release area in the area of the boss 31, avoiding material tearing caused by stress concentration during the shearing process. At the same time, the coordinated action of the lower support member 211 and the cutting edge keeps the profile in a stable posture at the moment of shearing, significantly reducing the dimensional deviation caused by vibration. The structure with double lower support members 211 for support can also adapt to profiles of different widths, and the quick die change can be realized by adjusting the distance between the lower support members 211, improving the processing flexibility of the equipment.

[0057] For example, a threaded hole is provided on one of the lower support members 211, and a blind hole is provided on the other. A distance adjusting screw is simultaneously passed through the threaded hole and the blind hole. By rotating the distance adjusting screw, the distance between the two lower support members 211 can be adjusted to adapt to profiles of different thicknesses.

[0058] In some embodiments, the cutting edge of the cutting edge is a wedge-shaped structure with a specific angle. The front angle of the cutting edge is 5° - 15°, and the rear angle of the cutting edge is 8° - 20°.

[0059] In the above embodiments, the rake angle design enables the cutting edge to efficiently penetrate the material, reducing resistance and controlling the chip flow direction; the clearance angle ensures an appropriate gap between the cutting edge and the surface of the support hanger 30, reducing friction and heat generation. This combination of angles distributes the shear force evenly along the cutting edge, effectively avoiding material tearing or deformation caused by stress concentration and significantly improving the flatness of the cut. The wedge-shaped structure forms a sharp shear surface during penetration, reducing burr generation. At the same time, through angle optimization, the service life of the cutting edge is extended and the wear rate is reduced.

[0060] Among them, the rake angle of the cutting edge can be 5°, 6°, 7°, 8°, 9°, 10°, 11°, 12°, 13°, 14°, 15°, etc., and the clearance angle of the cutting edge can be 8°, 9°, 10°, 11°, 12°, 13°, 14°, 15°, 16°, 17°, 18°, 19°, 20°, etc.

[0061] As Figure 6 and Figure 7 shown, in some embodiments, the working surface of the second fixed mold 11 is provided with a third groove portion 111 and two fourth groove portions 112. The two fourth groove portions 112 are respectively arranged on both sides of the third groove portion 111. The third groove portion 111 is used to oppose the contour of the boss 31 on the second surface B, and the fourth groove portion 112 is adapted to the contour of the concave portion 32 on the second surface B. There is a pointed end portion 113 between the third groove portion 111 and the fourth groove portion 112, and the pointed end portion 113 is used to be clamped at the connection of the boss 31 portion and the concave portion 32.

[0062] In the above embodiments, the pointed end portion 113 is used to be clamped at the connection of the boss portion 31 and the concave portion 32 on the second surface B, and the third groove portion 111 is adapted to the contour of the concave portion 32 on the second surface B, so as to accurately position the profile, ensure that the profile is in the correct position between the first mold half 13 and the second mold half, and guarantee the accuracy of subsequent bending processing. During the bending process, the third groove portion 111 provides support for the boss portion 31, and cooperates with the first protruding portion 131 and the second protruding portion 132 on the first mold half 13, so that the boss portion 31 is more evenly stressed and prevented from shifting or deforming due to uneven stress; the fourth groove portion 112 supports and restricts the bottom of the concave portion 32, enhances the fixing effect on the overall profile, and cooperates with the first mold half 13 and the second mold half, so that each part of the profile is evenly stressed, avoiding problems such as edge wrinkling and local deformation, and improving the bending quality. The pointed end portion 113 is clamped at the connection of the boss portion 31 and the concave portion 32, which can further enhance the positioning and restraint of the profile, making the profile not prone to sliding and displacement during bending and ensuring the accuracy of the bending angle. At the same time, the existence of the pointed end portion 113 can disperse stress, avoid stress concentration at the connection of the boss portion 31 and the concave portion 32, reduce the risk of cracking or damage of the material at this part, and further improve the quality and stability of bending. The setting of the third groove portion 111 reduces the contact area with the boss portion 31, improves the positioning accuracy through local pressure concentration during the bending process, reduces the frictional resistance and die wear, and at the same time uses the adaptability of the groove contour and the boss portion 31 contour to guide the material flow, avoiding deformation or cracking caused by stress concentration during bending, and ensuring the stable connection between the boss portion 31 and the concave portion 32 after bending.

[0063] Wherein, the end of the pointed end portion 113 has a smooth transition.

[0064] In addition, when the rotary die 12 is in the first position, the second mold half of the rotary die 12 and the second fixed die 11 are arranged side by side and the adjacent end faces abut against each other.
