Description

Technical Field

[0001] This utility model relates to the technical field of blank cutting devices, specifically to a graphite sawing limit device. Background Technology

[0002] Graphite electrodes are a common material used in electric furnaces. They are made primarily from petroleum coke and needle coke. Before processing, the graphite blank is placed on a saw. During the cutting process, the graphite blank is kept stationary while being cut by a cutting blade. After the blank is cut, the equipment pushes it forward a short distance to continue the cutting process.

[0003] This method of material preparation requires the graphite blank to remain stationary while being cut with a cutting blade, resulting in low cutting efficiency. Furthermore, in addition to using clamps to hold and position the graphite blank, a propulsion device is also needed to move the graphite blank forward, which increases the procurement cost of the cutting and material preparation equipment.

[0004] In view of this, the applicant proposes a new technical solution that integrates the clamp and the propulsion device, thereby reducing the equipment procurement cost. Utility Model Content

[0005] Therefore, this utility model provides a graphite sawing limit device to solve the problem of high procurement costs caused by the complexity of the material feeding equipment in the prior art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] This utility model discloses a sawing limiting device for a graphite sawing machine, including:

[0008] The base has an internal transmission device.

[0009] Two limiting brackets are symmetrically arranged on the top of the base, wherein the transmission device is adapted to drive the two limiting brackets to move towards each other;

[0010] A V-shaped block is disposed on the top of the limiting bracket and integrally formed with the limiting bracket;

[0011] Mecanum wheels, in pairs, are mounted on the V-block and are adapted to clamp the billet by means of the Mecanum wheels.

[0012] Furthermore, the transmission device includes:

[0013] A worm gear has a lead screw at its axis, and the two ends of the lead screw have threads with opposite directions of rotation.

[0014] A worm gear is rotatably mounted on the base, and the worm gear is meshed with the worm wheel for transmission.

[0015] A crank handle is installed at the end of the worm gear.

[0016] Furthermore, the Mecanum wheel includes:

[0017] Hub motors are mounted in pairs on the V-blocks;

[0018] The hub is coaxially connected to the hub motor at its axis, and several rollers are circumferentially mounted on the outer contour surface of the hub.

[0019] The roller axis is at a 45-degree angle to the end face of the hub.

[0020] Furthermore, the roller is provided with anti-slip texture.

[0021] Furthermore, the hub motor is a servo motor equipped with a frequency converter.

[0022] Furthermore, the limiting bracket includes:

[0023] The main support has an integrally formed top with the V-shaped block and a guide groove at the bottom, which is slidably mounted on the base.

[0024] A threaded hole is provided on the side of the main bracket, and the threaded hole is inserted into the lead screw and forms a helical pair with the thread.

[0025] Furthermore, the V-block includes:

[0026] The block body has a bottom connected to the limiting bracket, and a pair of through slots are symmetrically arranged on the inner side of the block body.

[0027] A slot is provided within the through groove for mounting the hub motor.

[0028] Furthermore, the roller is made of rubber.

[0029] This utility model has the following advantages:

[0030] The graphite sawing limiting device disclosed in this utility model drives the limiting bracket to move through the transmission device, and uses the Mecanum wheel installed on the limiting bracket to clamp and limit the graphite billet. When it is necessary to push the graphite billet, the Mecanum wheel clamping the graphite billet rotates to give the graphite billet a linear or rotational speed, thereby changing the position of the graphite billet without adding additional equipment, thus facilitating graphite unloading and solving the problem of high procurement costs caused by the complexity of unloading equipment in the prior art.

[0039] The following specific embodiments illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0040] Please refer to this as well. Figures 1-5The graphite sawing limiting device disclosed in this utility model includes a base 1, a transmission device 2, a limiting bracket 3, a V-block 4, and a Mecanum wheel 5. A pair of limiting brackets 3 are slidably arranged on the top of the base 1. The two limiting brackets 3 are symmetrically arranged and driven by the transmission device 2 to move towards each other on the top of the base 1, thereby effectively limiting the blank.

[0041] In this embodiment, a V-shaped block 4 is provided on the top of the limiting bracket 3, and Mecanum wheels 5 are installed in pairs on the V-shaped block 4. The V-shaped block 4 and the limiting bracket 3 are integrally formed to ensure the connection strength between the two and to be suitable for clamping the blank through the Mecanum wheels 5.

[0042] In some embodiments, such as Figure 2 The transmission device 2 includes a worm gear 21 and a worm 24. A lead screw 22 is provided at the axis of the worm gear 21. Furthermore, the two ends of the lead screw 22 are provided with threads 23 in opposite directions, and the two ends of the lead screw 22 are inserted into the threaded holes 33 of the limiting bracket 3. The threaded holes 33 and the threads 23 form a helical pair to achieve the transmission effect. On the other hand, the worm 24 is rotatably provided on the base 1. The worm 24 is meshed with the worm gear 21 for transmission. At the same time, the worm gear 21 drives the lead screw 22 to rotate. In this embodiment, the output power can be significantly improved by the transmission between the worm gear 21 and the worm 24 and the combination of the threaded transmission pair. A crank 25 is installed at the end of the worm 24, so that the two limiting brackets 3 can be moved by manually cranking the crank 25.

[0043] In some embodiments, such as Figure 5 The surface of the blank abuts against four Mecanum wheels 5 mounted on two limiting brackets 3. Each Mecanum wheel 5 includes a hub motor 51, a hub 52, and rollers 53. The rollers 53 are made of rubber and have anti-slip textures on their outer surfaces to increase the coefficient of friction between the rollers 53 and the blank surface. Several rollers 53 are circumferentially mounted on the outer contour surface of the hub 52, and the axes of the rollers 53 are at a 45-degree angle to the end face of the hub 52. When the hub 52 rotates, the linear velocity of the outer edge of the hub 52 is decomposed into tangential and radial components by the rollers 53.

[0044] In this embodiment, the hub motor 51 is coaxially connected to the axis of the hub motor 52. The hub motor 51 is a servo motor with a frequency converter installed. This allows the angular velocity of the rotation of the four hubs 52 to be controlled independently. By applying different linear velocities to the four hubs 52, a force is generated at the contact point between the roller and the surface of the blank to push the blank forward or rotate. Thus, the position of the blank can be freely adjusted when cutting the blank without the need for additional auxiliary equipment to move the blank.

[0045] In this embodiment, as Figure 4The limiting bracket 3 includes a main bracket 31 and a threaded hole 33. The top of the main bracket 31 is integrally formed with the V-block 4, and the bottom of the main bracket 31 is provided with a guide groove 32, which is slidably mounted on the base 1 to provide guidance. In addition, a threaded hole 33 is provided on the side of the main bracket 31. The threaded hole 33 is suitable for inserting a lead screw 22 and forming a helical pair with the thread 23. Since the thread 23 is provided at both ends of the lead screw 22 and has opposite directions of rotation, when the lead screw 22 rotates, the two main brackets 31 can move synchronously under the action of the threaded pair and the guide pair.

[0046] In this embodiment, the V-shaped block 4 includes a block body 41 and a slot 42. The portion of the block body 41 is connected to the limiting bracket 3, and a pair of through slots 43 are symmetrically arranged on the inner side of the block body 41. The slot 42 is disposed within the through slots 43 for mounting the hub motor 51. Although the present invention has been described in detail above with general descriptions and specific embodiments, modifications or improvements can be made to it, which are obvious to those skilled in the art. Therefore, all such modifications or improvements made without departing from the spirit of the present invention fall within the scope of protection claimed by the present invention.
