[0027] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0028] Reference Figures 1 to 4 The aluminum rod feeding machine of this utility model is illustrated in the following embodiments:

[0029] An aluminum rod feeding machine includes: a base frame, a feeding slide, and a feeding gripper 300.

[0030] The rod feeding slide is slidably connected to the base frame in the front-back direction. The base frame is provided with a rod feeding drive component 100 and a base frame 110. The rod feeding drive component 100 and the base frame 110 are used to drive the rod feeding slide to move back and forth relative to the base frame.

[0031] The bar-feeding gripper 300 is located at the front end of the bar-feeding slide. The bar-feeding gripper 300 includes an upper clamping member 310, a lower clamping member 320, and a clamping drive mechanism 330. The upper clamping member 310 has an upper clamping portion 311, and the lower clamping member 320 has a lower supporting portion 321. The upper clamping member 310 and the lower clamping member 320 are arranged vertically. Both the upper clamping member 310 and the lower clamping member 320 are rotatably connected to the bar-feeding slide. The clamping drive mechanism 330 is used to drive the upper clamping member 310 and the lower clamping member 320 to rotate relative to the bar-feeding slide, so that the upper clamping portion 311 and the lower supporting portion 321 move closer together or further apart.

[0032] In practical use, the clamping drive mechanism 330 can drive the bar-feeding gripper 300 to clamp the aluminum bar through the upper clamping part 311 and the lower supporting part 321. After the bar-feeding gripper 300 clamps the aluminum bar, the bar-feeding drive component 100 and the base frame 110 can drive the bar-feeding slide to move forward, realizing the extrusion and feeding action of the aluminum bar. After the bar feeding is completed, the clamping drive mechanism 330 can drive the upper clamping part 310 and the lower clamping part 320 to flip, so that the upper clamping part 311 and the lower supporting part 321 are separated, thereby avoiding the aluminum bar when the bar-feeding slide returns to its original position.

[0033] In this embodiment, the rod-feeding slide includes a base and a rod-feeding bracket 220. The base is slidably disposed on the upper side of the base frame in a front-back direction, and the rod-feeding bracket 220 is disposed on the upper side of the base. The lower end of the rod-feeding bracket 220 is fixedly connected to the base, and the upper front end of the rod-feeding bracket 220 is provided with an upper cantilever 221 extending forward in a cantilever structure. The rod-feeding gripper 300 is provided with the front end of the upper cantilever 221.

[0034] The upper cantilever 221 at the upper end of the bar feeding bracket 220 allows the bar feeding gripper 300 to be positioned in front of the bar feeding slide, thereby facilitating the bar feeding gripper 300 to extend from one side of the extruder into the space between the extrusion cylinder and the extrusion rod of the extruder to achieve extrusion feeding and avoid collisions or interference between the bar feeding slide and the upper and lower crossbeams or other components of the extruder.

[0035] The pre-extrusion tail material of the aluminum rod can be pieced together in the length-fixing equipment to avoid aluminum waste. To achieve extrusion feeding of multiple pieced aluminum rods, multiple feeding grippers 300 are used, and the number of feeding brackets 220 matches the number of feeding grippers 300. Each feeding gripper 300 is correspondingly positioned at the front end of each feeding bracket 220. In actual use, multiple feeding grippers 300 can clamp multiple aluminum rod segments at different positions, thus preventing unstable clamping of multiple aluminum rod segments.

[0036] In this embodiment, there are two of each of the bar-feeding grippers 300 and the bar-feeding brackets 220. Generally, two sections of aluminum bar tail material are used to assemble the bar for feeding; in a few cases, three sections are used. Stable clamping can be achieved using two of the aforementioned bar-feeding grippers 300.

[0037] The two rod feeding brackets 220 are arranged side by side, and both rod feeding brackets 220 are mounted on the upper side of the base. The base is provided with a variable pitch drive component 230 for driving the two rod feeding brackets 220 to move closer together or further apart.

[0038] To ensure that the end of the aluminum rod is close to the extrusion cylinder each time it is fed, one of the rod feeding brackets 220 is fixedly connected to the base, and the variable pitch drive component 230 is drivenly connected to the other rod feeding bracket 220, allowing it to move left and right relative to the base. In this embodiment, the two rod feeding brackets 220 are designated as a left bracket and a right bracket. The left bracket is fixedly mounted on the upper left side of the base, and the right bracket is slidably connected to the base in the left-right direction. The variable pitch drive component 230 is used to drive the right bracket to move left and right.

[0039] In this embodiment, the rod feeding drive component 100, the base frame 110, and the variable pitch drive component 230 all adopt a gear and rack drive structure.

[0040] Specifically: the bar feeding drive component 100 and the base frame 110 include: a bar feeding drive unit 111, a bar feeding drive rack 112, and a bar feeding drive gear 113. The bar feeding drive rack 112 extends in the front-rear direction and is fixedly connected to the base frame. The bar feeding drive gear is rotatably mounted on the base and meshes with the bar feeding drive rack 112 for transmission. The bar feeding drive unit 111 is drivenly connected to the bar feeding drive gear 113.

[0041] The variable pitch drive component 230 includes: a variable pitch drive unit 231, a variable pitch drive rack 232, and a variable pitch drive gear 233. The variable pitch drive rack 232 extends in the left-right direction and is fixedly connected to the base. The variable pitch drive gear 233 is rotatably mounted on the right bracket and meshes with the variable pitch drive rack 232 for transmission. The variable pitch drive unit 231 is drivenly connected to the variable pitch drive gear 233.

[0042] To facilitate control of the conveying speed and accuracy, both the rod feeding drive unit 111 and the pitch-changing drive unit 231 in this embodiment are servo motors. In other embodiments, the rod feeding drive unit 111 and the pitch-changing drive unit 231 can be rotary drive components such as stepper motors or pneumatic motors. In other embodiments, the rod feeding drive component 100, the base frame 110, and the pitch-changing drive component 230 can also be linear drive components such as cylinders, electric push rods, hydraulic push rods, or lead screw and nut drive assemblies.

[0043] To facilitate the feeding of aluminum bars into the bar feed gripper 300, the lower support section 321 is equipped with a roller assembly 322. The roller assembly 322 has multiple heat-resistant rollers arranged rotatably in a left-right direction. These heat-resistant rollers form a left-right extending support surface, providing support for the high-temperature aluminum bar. The heat-resistant rollers roll and abut against the high-temperature aluminum bar, greatly reducing the frictional resistance experienced by the high-temperature aluminum bar. In actual use, the high-temperature aluminum bar can be pushed into the upper side of the lower support section 321 in a left-right direction. Furthermore, after the aluminum bar is fed into the extrusion press, it can be pushed into the extrusion cylinder by the extrusion rod when clamped by the bar feed gripper 300.

[0044] The outer periphery of the heat-resistant roller is provided with a heat-resistant layer. The material of the heat-resistant layer can be cast iron, stainless steel, polyurethane, phenolic resin, etc., which can maintain good physical properties and wear resistance at high temperatures.

[0045] To provide effective support for the aluminum rod, the roller assembly 322 is larger in the lateral direction, thus supporting a wider area of ​​the aluminum rod. In this embodiment, the lateral dimension of the roller assembly 322 is larger than that of the lower clamp 320, the upper clamp 310, and the rod feeding bracket 220. To avoid obstruction during rod feeding, one end of the roller assembly 322 is positioned close to the outer side of the rod feeding gripper 300, while the other end extends inward.

[0046] Specifically: In the bar-feeding gripper 300 located on the left side, the distance between the left end of the roller assembly 322 and the lower clamp 320 is less than the distance between its right end and the lower clamp 320; in the bar-feeding gripper 300 located on the right side, the distance between the right end of the roller assembly 322 and the lower clamp 320 is less than the distance between its left end and the lower clamp 320. The roller assembly 322 is offset at the front end of the lower clamp 320, which enables it to support the aluminum bar while avoiding the extrusion cylinder and extrusion rod of the extrusion press as much as possible, thus avoiding obstruction to the bar-feeding process.

[0047] In this embodiment, in order to provide stable support for the aluminum rod, there are multiple lower support parts 321, and the multiple lower support parts 321 are arranged at the front end of the lower clamp 320.

[0048] For cylindrical aluminum bars, the lower clamp 320 has a clamping axis extending laterally at its front end, and multiple lower support portions 321 are circumferentially distributed around the clamping axis. These circumferentially distributed lower support portions 321 support multiple positions on the underside of the aluminum bar. Generally, to accommodate cylindrical aluminum bars of different diameters, each lower clamp 320 has two lower support portions 321. It should be noted that the clamping axis described above is a virtual feature, set up to facilitate accurate description of the positional relationship of the multiple lower support portions 321.

[0049] The lower support portion 321 supports the aluminum rod by providing a support surface extending in the left-right direction. In order for two adjacent rod feeding brackets 220 to be close to each other, the lower support portions 321 of two adjacent rod feeding grippers 300 are staggered in the left-right projection.

[0050] The two feed grippers 300 on the left and right sides have their respective lower material support portions 321 as the left material support portion 341 and the right material support portion 342. Referring to the projection in the left-right direction... Figure 3 The left and right material support parts 341 and 342 are arranged alternately. When the two feeding grippers 300 approach each other, the left and right material support parts 341 and 342 can avoid each other, thereby adapting to feeding aluminum bars with shorter axial dimensions.

[0051] Both the upper clamp 310 and the lower clamp 320 have a hinged end, a driving end, and a working end. The upper clamping part 311 and the lower material supporting part 321 are both located at the working end. The hinged end is rotatably hinged to the feeding rod slide, and the clamping driving mechanism 330 is drively connected to the driving end.

[0052] Reference Figure 3In this embodiment, the hinge end of the upper clamping member 310 is located at the upper front end of the upper cantilever 221, and the hinge end of the lower clamping member 320 is located at the lower front end of the upper cantilever 221. The clamping drive mechanism 330 includes an upper clamping cylinder 331 and a lower clamping cylinder 332. The cylinder bodies of both the upper clamping cylinder 331 and the lower clamping cylinder 332 are rotatably hinged to the upper cantilever 221. The piston rod end of the upper clamping cylinder 331 is drive-hinged to the driving end of the upper clamping member 310, and the piston rod end of the lower clamping cylinder 332 is drive-hinged to the driving end of the lower clamping member 320.

[0053] In this embodiment, both the upper clamping cylinder 331 and the lower clamping cylinder 332 are hydraulic cylinders. In other embodiments, the upper clamping cylinder 331 and the lower clamping cylinder 332 may also be linear drive components such as pneumatic cylinders, electric push rods, or lead screw and nut drive assemblies.

[0054] Because aluminum bars are relatively heavy, the front end of the lower clamp 320 experiences a large load during actual use. In a further embodiment, the hinge end of the lower clamp 320 is located in its middle, while the working end and driving end are located at its front and rear ends, respectively. In the lower clamp 320, the distance between the driving end and the hinge end is greater than the distance between the working end and the hinge end, thereby increasing the torque of the lower clamping cylinder 332 and reducing the output force required for the lower clamping cylinder 332.

[0055] When using the aluminum rod feeder of this utility model to feed rods into the extruder:

[0056] First, the lower clamping cylinder 332 of the bar-feeding gripper 300 presses down against the drive end of the lower clamping body, causing the working end to swing upward to its limit position. At this time, the aluminum bar can be conveyed to the lower support portion 321 of the two bar-feeding grippers 300 in the left-right direction. Next, the upper clamping cylinder 331 drives the upper clamping member 310 to rotate, clamping the aluminum bar through the upper clamping portion.

[0057] During the above process, the variable pitch drive component 230 can drive the right support to move left and right, so that the distance between the two bar feeding grippers 300 can adapt to the length of the aluminum bar.

[0058] Then, the rod feeding drive component 100 and the base frame 110 drive the rod feeding slide forward to feed the aluminum rod into the extruder. After the extruder clamps or pushes the aluminum rod into the extrusion cylinder, the upper clamping cylinder 331 and the lower clamping cylinder 332 are activated, causing the upper clamping part 311 and the lower supporting part 321 to flip up and down respectively, thereby releasing the aluminum rod.

[0059] Finally, the rod feeding drive component 100 and the base frame 110 drive the rod feeding slide to reset backward, waiting for the next rod feeding.
