Description

Technical Field

[0001] The invention relates to the field of machining, and in particular to a peeling device for round bars. Background Art

[0002] During the production process of cast rods, due to uneven cooling in various areas and the influence of changes in the external environment, there is usually a certain degree of segregation layer on the surface of the cast rods, and some oil and oxides are also mixed in. Usually, cast rods such as aluminum rods are used as raw materials for hot processing and need to be further processed, such as extrusion, rolling, etc. Taking extrusion as an example, due to the presence of segregation layers and surface dirt on cast rods, they will flow into the interior of the product during the extrusion process, causing a certain degree of product defects and reducing the yield of the product. Therefore, the peeling process is particularly important in production. The peeling machine equipment on the market is expensive, and the tool is easily damaged. Therefore, many small and medium-sized extrusion deep processing companies do not generally adopt the process method of peeling before extrusion. Therefore, it is particularly important to provide a simple, easy and low-cost peeling method.

[0003] At present, the commonly used method for stripping cast rods is:

[0004] The first is the lathe, which uses a lathe to remove the cold cast rod in sections, relying on the longitudinal feed of the tool and the high-speed rotation of the cast rod to achieve the effect of removing the skin;

[0005] The second is hot peeling, which uses a built-in heating rod furnace to heat the cast rod, and then uses a special peeling machine to peel the cast rod. This device uses a fixed tool and the thrust of the push rod to peel the cast rod. Summary of the invention

[0031] In order to make the purpose, technical scheme and advantages of the embodiments of the present invention clearer, the technical scheme in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention. It should be noted that the embodiments in this application and the features in the embodiments can be combined with each other arbitrarily without conflict.

[0032] The present invention peels the bar material by adopting a method of rotating and longitudinally feeding the peeling tool. The peeling tool is positioned by an auxiliary gear and driven to rotate by a transmission gear. A plurality of cutters are arranged inside the peeling tool, so the peeling effect is good and the power consumption is low.

[0033] The peeling device provided according to the present invention is described in detail below with reference to the accompanying drawings.

[0034] In order to make this description more clearly express the design intention of the present invention, the skinning tool involved in the present invention is defined as follows: in the working state, the side facing the rod is the front end, and the opposite side is the rear end; the side of the knife body that first contacts the rod is the front knife surface, and the other opposite side is the rear knife surface.

[0035] like Figure 1 As shown, the skinning device includes a skinning tool 7, which is an external gear structure, and p auxiliary gears 6 are arranged on the outside of the skinning tool 7 and meshed with the external gear of the skinning tool 7, p is a positive integer greater than or equal to 3, and the p auxiliary gears 6 are used to limit the position of the skinning tool 7 to ensure that the skinning tool 7 rotates along its own axis; the p auxiliary gears 6 are rotatably fixed on the fixed bracket 9 through the bearing 4 and the rotating shaft 5, and the fixed bracket 9 is fixed on the transmission device 2; p can be 3, 4, 5, etc. Preferably, the skinning device involved in the present invention uses 4 auxiliary gears, which are evenly distributed along the outer circle of the skinning tool 7 and meshed with the skinning tool 7 respectively. This arrangement can make the skinning tool rotate more smoothly, the force is balanced during skinning, and the installation is relatively simple;

[0036] The transmission gear 8 is connected to the motor 3 through a coupling and meshes with the peeling tool 7 to provide kinetic energy for the peeling device; the motor 3 is fixed on the transmission device and can move with the peeling tool 7;

[0037] The transmission device 2 is slidably arranged on the guide rail 1 to provide longitudinal feed for the peeling knife 7 to ensure the continuous peeling work.

[0038] like Figures 2 to 6 As shown, the skinning tool includes a gear tool holder 71 and n tool bodies 75, the gear tool holder 71 is an external gear, and the n tool bodies 75 are arranged on the inner circle of the gear tool holder 71, and n is a positive integer greater than or equal to 1; the tool body 75 is provided with a main edge 76 and a side edge 77, the main edge 76 is along the axial direction of the gear tool holder 71, and the side edge 77 is arranged on the side of the tool body 75 facing the rod material, and the angle α between the main edge 76 and the tool body 75 is α.

[0039] The front cutting surface 761 of the main cutting edge 76 is a concave arc shape.

At the same time, arc grooves 74 are provided on both sides of the cutter seat 72, so that the cutter body 75 can move along the arc grooves 74, and the peeling tool 7 is suitable for peeling work of bars of various different diameters.

[0042] The n tool seats 72 are evenly distributed along the inner circle of the gear tool holder 71 .

[0044] The external gear module m of the gear tool holder 71 is 2, and the number of teeth is z=30~80. Preferably, z=50 in the present invention; the number of tool seats 72 is n=2~8, and n can be 2, 3, 4, 5, 6, 7, 8 during use; preferably, n=3 in the present invention, and the three tool seats 72 are evenly distributed in the circumference, wherein the arc length of the root of the tool seat accounts for 1 / 16 of the circumference length. The tool seat itself has sufficient strength, and three tool bodies are installed in addition, which can ensure the stability and efficiency of the peeling process and facilitate the removal of waste chips.

[0045] The transmission device 2 is disposed on the guide rail 1 , and drives the fixed bracket 9 and the motor 3 to move along the guide rail 1 .

[0046] The fixed bracket 9 includes a front fixed plate 91 and a rear fixed plate 92, and the front fixed plate 91 and the rear fixed plate 92 are respectively provided with through holes, and the through holes are concentric with the inner circle of the skinning knife 7; the protective cover 10 is respectively fixedly connected to the front fixed plate 91 and the rear fixed plate 92; the fixed bracket 9 serves as a supporting structure of the gear system, and after the protective cover 10 is connected, it can provide good protection for the operator and effectively protect the gear system and the skinning knife 7.

[0047] The peeling method of the peeling device is as follows:

[0048] The rod is fixed with an adjustable support device, one end of the rod is aligned with the front fixing plate, and the outer circle of the rod is concentric with the inner circle of the peeling knife 7;

[0049] According to the outer diameter of the rod, adjust the screw 73 of the peeling knife 7 so that the inscribed circle of the main cutting edge 76 of the n blade bodies 75 is concentric with the rod and the diameter is 0.4 to 1 mm smaller than the outer diameter of the rod;

[0050] Adjust the control system parameters according to the material of the rod, including the motor speed and the linear moving speed of the transmission device 2;

[0051] The skinning device is started, and the motor drives the skinning knife 7 to rotate through the transmission gear. The rotating skinning knife 7 cuts off the outer skin of the bar material it contacts, and the transmission device 2 moves toward the bar material along the guide rail, so that the skinning knife 7 continues to cut off the outer skin of the bar material.
