Description

Technical Field

[0001] This invention relates to the field of casting processing technology, and more particularly to a support assembly and a bending machine. Background Technology

[0002] After die casting, the workpiece often has slag pockets and slag stalks. Therefore, a bending machine is needed to remove these. When bending die castings, the bending machine first removes the workpiece from the previous casting process. The bending machine's clamping and flipping mechanism then flips the workpiece to a suitable processing angle and places it on the bending machine's support block to begin the bending process. The support block needs to have a lifting function to avoid the clamping and flipping motion of the workpiece, and it only supports the workpiece after it has been clamped and flipped.

[0003] The existing bending machine uses a hydraulic cylinder to drive the support block to swing and lift the support block. One hydraulic cylinder drives two symmetrically arranged support blocks. The shape of the support block is suitable for providing support for the machining of parts with shaft-like structures. However, since the hydraulic cylinder can only drive two symmetrically arranged support blocks on both sides, it can only support a maximum of one die-casting part with two parts, resulting in low processing efficiency and poor versatility. Summary of the Invention

[0004] The purpose of this invention is to provide a support component and a bending machine. The support block of the support component can achieve linear lifting and lowering, and can support workpieces of any shape, with strong processing versatility. The bending machine has a compact structure and can be equipped with multiple support blocks to bend workpieces produced in multiple batches during casting, with high bending efficiency.

[0016] A guide sleeve is fixedly connected to the fixed frame. The guide sleeve has a guide hole, and the guide rod is slidably connected in the guide hole.

[0017] As a preferred structure of the present invention, it further includes a baffle, which is fixedly connected to the fixed frame and disposed below the support mechanism. The baffle is provided with an inclined baffle platform, which is inclined downward in a direction away from the fixed frame, and the guide rod passes through the inclined baffle platform.

[0025] As a preferred embodiment of the present invention, the folding assembly further includes a buffer member for providing cushioning for the lifting plate.

[0026] The beneficial effects of this invention are as follows: The support assembly provided by this invention is equipped with a support mechanism, which includes at least two support blocks.

[0035] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, and not all of the structures.

They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the present invention. In addition, the terms "first" and "second" are used only for distinction in description and have no special meaning.

[0039] like Figures 1-4 As shown, this embodiment of the invention provides a support assembly for a bending machine, including a fixed frame 11, a support mechanism 12, and a lifting mechanism 13. The fixed frame 11 includes a platform 111 configured to support a workpiece 100. The support mechanism 12 is slidably connected to the fixed frame 11 and includes a support platform 122 and at least two support blocks 121, which are detachably connected to the support platform 122. The lifting mechanism 13 is configured to linearly lift the support mechanism 12 and cause the support blocks 121 to abut against the workpiece 100.

[0040] The processed part 100 is a casting, including a slag pot 101, a material handle 102, and a workpiece body 103. In this embodiment of the invention, the processed part 100 is cast in one step, including at least two workpiece bodies 103. In other embodiments, the processed part 100 may have more than two workpiece bodies 103, that is, the processed part 100 may also be a multi-cast part, not limited to this embodiment. After the processing part 100 is cast in the previous process, it is picked up and flipped into the support assembly of the bending machine and adjusted to an angle that facilitates bending operations.

[0041] When the workpiece 100 is flipped, the support mechanism 12 is located below the table 111 to avoid the flipping action; when the workpiece 100 completes the clamping and flipping action and is placed on the table 111, the lifting mechanism 13 lifts the support mechanism 12 in a straight line and makes the support block 121 abut against the workpiece 100 to provide support for the workpiece 100.

[0042] The support assembly of this embodiment includes a support mechanism 12 comprising at least two support blocks 121. The support blocks 121 move linearly, enabling the bending and processing of multi-cast workpieces 100 with high processing efficiency. The support blocks 121 used to provide support can be varied according to the shape of the workpiece 100. When changing machine types, only different support blocks 121 need to be replaced, resulting in strong processing versatility. The lifting mechanism 13 can linearly lift the support mechanism 12, avoiding interference with the flipping action. Moreover, during the linear lifting motion, the support blocks 121 abut against the workpiece 100 from below the platform 111. The shape of the support blocks 121 is not limited by the movement trajectory of the lifting mechanism 13, allowing support for workpieces 100 of any shape, resulting in strong equipment versatility.

[0043] Furthermore, the lifting mechanism 13 includes a power component 131, which comprises a cylinder and a piston rod 1311. The piston rod 1311 is capable of linear extension and retraction within the cylinder. One end of the cylinder is hinged to the fixed frame 11, and the end of the piston rod 1311 away from the cylinder is hinged to the support mechanism 12. In this embodiment, the power component 131 is hinged to the fixed frame 11 at an inclined angle. The inclined installation of the power component 131 occupies less space and can avoid other structural components of the bending machine. With the power output of the power component 131, the piston rod 1311 can drive the support mechanism 12 to move; through the guiding action of the guide rod 132, the support mechanism 12, driven by the piston rod 1311, only performs linear lifting motion. Preferably, the power component 131 is a hydraulic cylinder. Hydraulic cylinders have a simple and compact structure, smooth movement, no transmission backlash, and a working temperature range up to 200℃, which can adapt to the high-temperature working environment of the bending machine.

[0044] Furthermore, the lifting mechanism 13 also includes a transition rod 133 and a support rod 134. The transition rod 133 connects the support mechanism 12 and the power component 131, with one end hinged to the piston rod 1311 and the other end hinged to the support platform 122. One end of the support rod 134 is hinged to the piston rod 1311, and the other end is hinged to the fixed frame 11. By hinged to the transition rod 133, the piston rod 1311 can increase the lifting height of the support mechanism 12, resulting in a more compact structure that meets the lifting requirements of large-sized workpieces. Preferably, the piston rod 1311, the transition rod 133, and the support rod 134 are hinged to the same axis, and the support rod 134 provides fixed support for the piston rod 1311 and the transition rod 133, avoiding instability in the lifting action of the lifting mechanism 13.

[0045] Furthermore, the lifting mechanism 13 is also provided with a guide component, which includes a guide rod 132 and a guide sleeve 135. One end of the guide rod 132 is detachably connected to the support platform 122; the guide sleeve 135 is fixedly connected to the fixing frame 11, and the guide rod 132 is slidably connected inside the guide sleeve 135. Preferably, the guide sleeve 135 adopts a linear bearing, and the inner hole of the bearing of the guide sleeve 135 is perpendicular to the platform of the fixing frame 11, so that the sliding direction of the guide rod 132 is perpendicular to the platform of the fixing frame 11, ensuring vertical guidance of the support block 121. Preferably, the number of guide sleeves 135 is the same as the number of guide rods 132, which further improves the stability of the guide rods 132 and avoids jamming of the linear lifting action of the lifting mechanism 13. In this embodiment, a total of four guide sleeves 135 are provided on each side of the support block 121, which are located at the four corners of the lower end face of the support platform 122, making the support more stable; in other embodiments, other numbers of guide rods 132 and guide sleeves 135 can also be provided, and this embodiment does not impose any restrictions.

[0046] Furthermore, the support assembly also includes a baffle 14, which is fixedly connected to the fixed frame 11 and positioned below the support mechanism 12. The baffle 14 has an inclined baffle platform 141 through which the guide rod 132 passes. The inclined baffle platform 141 is inclined downwards away from the fixed frame 11, facilitating the falling of the slag bag 101 and the material handle 102 after folding onto the baffle 14 and sliding down the inclined baffle platform 141, where they are collected by the waste basket below the fixed frame 11. This prevents waste from falling into the lifting mechanism 13 and affecting the lifting action.

[0047] Furthermore, the support block 121 is provided with a support groove 1211, which engages with the workpiece body 103 of the workpiece 100. Preferably, the shape of the support groove 1211 conforms to the shape of the workpiece body 103, providing stable support for the workpiece body 103.

[0048] Furthermore, this embodiment of the invention also provides a bending machine, including the above-mentioned support assembly, and further provided with a bending assembly 2, which is fixedly connected to the frame of the bending machine. The bending assembly 2 is configured to bend the slag bag 101 and the material handle 102 of the workpiece 100.

[0049] Furthermore, the folding assembly 2 includes a plurality of first folding blocks 21, a plurality of second folding blocks 22, and a lifting plate 23. The first folding blocks 21 are configured to fold away the slag bag 101 of the workpiece 100; the second folding blocks 22 are configured to fold away the slag bag 101 and the material handle 102 of the workpiece 100; the plurality of first folding blocks 21 and the plurality of second folding blocks 22 are detachably connected to the lifting plate 23, and the lifting plate 23 can drive the first folding blocks 21 and the second folding blocks 22 to rise and fall, and the lifting plate 23 is located above the platform 111.

[0050] During the bending process, the lifting plate 23 drives the first bending block 21 and the second bending block 22 to descend for the first time. The first bending block 21 and the second bending block 22 are used to remove the slag bag 101 on the workpiece 100. Then, the lifting plate 23 drives the first bending block 21 and the second bending block 22 to descend for the second time. The second bending block 22 further cuts off the connection between the workpiece body 103 and the material handle 102, thereby removing the material handle 102. In this embodiment, the bending assembly 2 includes two first bending blocks 21 and two second bending blocks 22, wherein the two first bending blocks 21 are arranged opposite each other, and the two second bending blocks 22 are arranged opposite each other. It should be noted that the first bending blocks 21 and the second bending blocks 22 are modular structural components. Their quantity and shape are determined according to the shape of the workpiece 100. When processing workpieces 100 of different materials, the first bending blocks 21 and the second bending blocks 22 can be replaced to meet the needs of the workpiece 100, making the equipment more versatile.

[0051] Furthermore, the second folding block 22 is provided with a folding groove 221. The end face of the folding groove 221 can abut against the slag bag 101, and the folding groove 221 can engage the workpiece body 103. During the process of the lifting plate 23 driving the second folding block 22 to descend twice, during the first descent, the end face of the folding groove 221 first contacts the slag bag 101 and uses the impact force to fold away the slag bag 101; during the second descent, the folding groove 221 gradually contacts the workpiece body 103 and finally engages the workpiece body 103, thereby severing the connection between the workpiece body 103 and the material handle 102, and realizing the removal of the material handle 102. At this time, the workpiece body 103 is fixed to the support assembly by the second folding block 22 and the support block 121, and the slag bag 101 and the material handle 102 fall off the support assembly as waste. Preferably, the bottom width of the folding groove 221 is smaller than the opening width, which facilitates the secure clamping of the workpiece body 103 during the second descent and prevents the workpiece body 103 from falling off the support block 121 when the material handle 102 is folded off.

[0052] Furthermore, the material-folding assembly 2 also includes a buffer 24, which provides cushioning for the lifting plate 23. During the two descents of the lifting plate 23, the buffer 24 provides cushioning to prevent the lifting plate 23 from causing surface scratches or damage to the workpiece body 103 due to excessive speed or impact force during descent. The specific structure and cushioning principle of the buffer 24 are existing technologies in the art and will not be described in detail here.

[0053] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the implementation of the present invention. Those skilled in the art will be able to make various obvious changes, readjustments, and substitutions without departing from the scope of protection of the present invention. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the scope of protection of the claims of the present invention.
