DETAILED DESCRIPTION

[0017] The following is combined with Figure 1-5 This application is described in further detail.

[0018] The embodiment of the present application discloses a straight rod hydraulic automatic feeding machine.

[0019] Reference Figure 1The straight rod hydraulic automatic unloading machine comprises a working platform 1 and a cutting unloading part and a feeding clamping part arranged on the working platform 1. The cutting unloading part comprises a support frame 2 fixedly arranged at one end of the working platform 1 and a cutting head 3 fixed on the support frame 2 and moved up and down by a cutting drive cylinder. The feeding clamping part comprises a feeding mechanism and a clamping mechanism. The feeding mechanism comprises two feeding cylinders 4. The axes of the two feeding cylinders 4 form a certain angle and are fixedly installed on the working platform 1 in a V-shaped symmetrical manner. A moving seat 5 is fixedly installed on the telescopic end of the feeding cylinder 4. A radial slide rail 6 is provided on the moving seat 5. A slider 7 is slidably installed on the radial slide rail 6. As shown in the attached Figure 2 As shown, a return spring 8 is provided between the movable seat 5 and the slider 7, a wheel axle 9 is provided on the slider 7, a one-way bearing 10 is fixedly installed on the wheel axle 9, a feed pressure wheel 11 is fixedly installed on the one-way bearing 10, and the clamping mechanism includes two groups of symmetrically arranged racks 12, gears 13, elastic rods 14 and clamping blocks 15, the racks 12 are fixedly installed on the slider 7, the racks 12 are meshed and connected with the gears 13, the gears 13 are rotatably installed on the working platform 1, one end of the elastic rod 14 is fixedly connected to the gears 13, and the other end of the elastic rod 14 is fixedly connected to the clamping block 15.

[0020] Working principle: The straight bar hydraulic automatic unloading machine realizes automatic unloading of bars through the cooperation of the cutting unloading part and the feeding clamping part on the working platform 1. The cutting unloading part is fixed by the support frame 2, and the cutting head 3 is moved up and down by the cutting drive cylinder to perform the cutting operation. The feeding mechanism is composed of a feeding cylinder 4 with two axes at a certain angle, which is installed in a V-shaped symmetrical manner, also known as an eight-shaped installation, to achieve stable feeding of bars. The moving seat 5 is installed at the telescopic end of the feeding cylinder 4, and cooperates with the slider 7 through the radial slide rail 6 to achieve smooth movement of the slider 7. The wheel shaft 9 and the one-way bearing 10 on the slider 7 support the feeding pressure wheel 11, and work together with the reset spring 8 to achieve stability and automatic reset during the feeding process. The clamping mechanism adopts a combination of a rack 12, a gear 13, an elastic rod 14 and a clamping block 15, and the clamping action of the clamping block is realized by the rotation of the gear.

[0021] As attached Figure 3 As shown in the figure, when the feeding cylinder 4 is extended, the two moving seats 5 move to the right and the distance between them becomes smaller. The two feeding pressure wheels 11 clamp the rod 18 under the left and right sides of the return spring 8 and drive the rod 18 to move to the right for a distance. The one-way bearing 10 ensures that the feeding pressure wheels 11 do not rotate when the feeding cylinder 4 is pushed forward. When the feeding cylinder 4 is extended, the gear drives the elastic rod 14 to open, so that the pressing block 15 is separated from the surface of the rod 18. As shown in the attached figure Figure 1As shown, when the feeding cylinder 4 is shortened, the two moving seats 5 move to the left and the distance between them increases. When the feeding pressing wheel 11 moves to the left, the feeding pressing wheel 11 rotates and slips, avoiding driving the rod 18 to move to the left. Repeating the telescopic movement of the feeding cylinder 4 can drive the rod 18 to move to the right. When the feeding cylinder 4 is shortened, the gear drives the elastic rod 14 to close, so that the pressing block 15 presses the rod 18 to improve its stability during cutting.

[0022] This application simplifies the hydraulic control system by reducing the number of hydraulic cylinders, reduces system complexity and failure rate, and solves the problems of the traditional straight rod hydraulic automatic unloading machine's complex hydraulic control system, high cost of use, and easy failure. The optimized V-shaped symmetrical feeding cylinder 4 layout improves the stability and accuracy of feeding, while reducing the number of hydraulic cylinders used. The coordination of the moving seat 5 and the slider 7, as well as the setting of the reset spring 8, improve the response speed and automatic reset ability of the feeding mechanism. The design of the clamping mechanism utilizes the meshing of the gear 13 and the rack 12, as well as the elasticity of the elastic rod 14, to achieve automatic clamping and release of the rod, and improve the clamping efficiency. The simplification of the overall structure not only reduces the cost of use, but also improves the reliability of the equipment and the convenience of maintenance.

[0023] The working platform 1 is provided with two slideways 16, which are parallel to the installation directions of the two feeding cylinders 4, respectively, and the slideways 16 are slidably connected to the moving seat 5. The moving seat moves freely along the slideways, ensuring that the movement direction of the moving seat 5 on the slideways is consistent with the pushing direction of the feeding cylinders. Guided by the slideways 16, the feeding pressure wheel 11 on the moving seat 5 can stably push the rods forward along the slideways, realizing a smooth feeding process. The setting of the slideways 16 enhances the structural stability of the entire feeding mechanism, ensuring stability under high speed or heavy load conditions.

[0024] In addition, the number of the feeding pressure wheels 11 on each slider 7 can be set to multiple. Multiple feeding pressure wheels 11 provide more contact points, which helps to more evenly distribute the pressure on the bar. Reduce the force on a single pressure wheel, reduce the wear of the pressure wheel and the bar, and improve the stability of the overall feeding process. Multiple pressure wheels arranged in a colinear manner can provide a stronger clamping force to ensure that the bar will not slide or deviate during the feeding process.

[0025] The clamping block 15 is slidably connected to the elastic rod 14. A limit rod is provided on the clamping block 15. The limit rod is slidably connected to the flange plate at one end of the elastic rod 14 and fixedly installed by a nut. A clamping spring 17 is fixedly connected between the clamping block 15 and the elastic rod 14. The clamping spring 17 provides continuous pressure to ensure that the clamping block can tightly clamp the rod. The clamping spring 17 can be fixedly installed on the limit rod.

[0026] The elasticity of the elastic rod 14 and the preload of the clamping spring 17 work together to improve the clamping efficiency and reduce the clamping time. The sliding connection between the clamping block 15 and the elastic rod 14 allows the clamping block to move in the radial direction of the rod, which helps to adapt to rods of different lengths. Due to the action of the clamping spring 17, the clamping block 15 can adapt to rods of different diameters to achieve a stable clamping effect.

[0027] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
