Description

Technical Field

[0001] This utility model relates to the field of channel steel processing technology, and in particular to a hot extrusion forming device for channel steel processing. Background Technology

[0002] In modern industrial production, channel steel, as a commonly used type of steel, is widely used in many fields such as construction, machinery manufacturing, and automotive industry. Hot extrusion forming process has become an important method for processing channel steel due to its high efficiency and precision. Channel steel hot extrusion forming is a processing technology in which metal billets are plastically deformed in a mold cavity under high temperature and strong pressure to obtain channel steel products with specific shapes, sizes and properties. During heating, the billet is heated to a suitable temperature range to achieve a good plastic state. The heating temperature needs to be determined according to the material of the billet.

[0003] Current hot extrusion molding equipment requires baffles on both sides of the mold groove, and the channel steel will remain in the mold groove after hot extrusion. When demolding, the side baffles need to be opened and then the demolding is done manually. The demolding process is cumbersome and labor-intensive, which affects the efficiency of hot extrusion molding of channel steel. Utility Model Content

[0004] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a hot extrusion forming device for channel steel processing that can overcome or at least partially solve the above problems.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A hot extrusion forming apparatus for processing channel steel includes: a worktable, and further includes: a lower die fixedly disposed on the worktable; a movable upper die disposed on the upper side of the lower die; a die groove disposed on the lower die; a stripper plate symmetrically disposed on both sides of the die groove; side baffles symmetrically disposed on both sides of the die groove, and the side baffles are fixedly connected to the stripper plate; and a drive assembly for driving the stripper plate to move.

[0007] Preferably, a gantry frame is fixedly connected to one side of the workbench, and a first hydraulic cylinder is symmetrically fixedly connected between the gantry frame and the upper mold.

[0008] To facilitate the rotation of the template, the drive assembly further includes a rotating shaft fixedly mounted on the side baffle, the rotating shaft being rotatably connected to the worktable, a mounting plate being fixedly connected to one side of the worktable, and a second hydraulic cylinder being rotatably mounted between the mounting plate and the side baffle.

[0009] To further improve the accuracy of channel steel positioning, an inclinometer is fixedly connected to the side baffle.

[0010] Preferably, the axis of the rotating shaft is located below the demolding template.

[0011] To facilitate the positioning of the channel steel raw material, a positioning groove is further provided on the upper side of the lower mold, and positioning chamfers are symmetrically provided on the upper side of the positioning groove. A feeding chamfer is provided on the upper edge of the mold groove.

[0012] Compared with the prior art, the present invention provides a hot extrusion forming device for channel steel processing, which has the following beneficial effects:

[0013] 1. This hot extrusion forming device for channel steel processing places channel steel raw material heated to a suitable temperature onto the lower mold. In the preparation state, the second hydraulic cylinder is in a retracted state. At this time, one end of the ejector plate is placed on the upper edge of the mold groove to support the placed channel steel raw material. Then, by controlling the two second hydraulic cylinders to extend simultaneously, the channel steel raw material is placed in the set position. At the same time, the two side baffles position the two ends of the channel steel raw material to make it centered. Then, the first hydraulic cylinder extends to push the upper mold downward, performing hot extrusion on the channel steel raw material between the upper and lower molds, so that the raw material is formed in the mold groove. After hot extrusion is completed, the second hydraulic cylinder is activated and retracted, driving the side baffles to rotate around the rotating shaft, which in turn drives the ejector plate to rotate, and ejects the formed channel steel from the mold groove. This realizes automated demolding, greatly improves demolding efficiency, reduces the labor intensity of workers, and facilitates automatic positioning of channel steel raw material, effectively improving the efficiency of hot extrusion forming of channel steel.

[0014] 2. The hot extrusion forming device for channel steel processing uses an inclinometer to detect the tilt angle of the side baffle. The inclinometer is connected to an external microcomputer, which acquires the tilt data in real time. This data information can then be used to control the second hydraulic cylinders on both sides, ensuring that the second hydraulic cylinders on both sides operate synchronously, thereby improving the accuracy of positioning the channel steel raw material.

[0015] 3. The hot extrusion forming device for channel steel processing first supports the channel steel raw material through the demolding template. During the slow rotation process, the channel steel raw material can be positioned front and back through the positioning chamfer, and then positioned left and right through the side baffle, thereby effectively improving the accuracy of hot extrusion forming of channel steel.

[0016] The parts not covered in this device are the same as or can be implemented using existing technologies. This utility model realizes automated demolding, which greatly improves demolding efficiency, reduces the labor intensity of workers, and facilitates automatic positioning of channel steel raw materials, effectively improving the efficiency of hot extrusion forming of channel steel, while also effectively improving the accuracy of positioning of channel steel raw materials.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] Example 1: Refer to Figures 1-3 A hot extrusion forming apparatus for processing channel steel includes: a worktable 1, characterized in that it further includes: a lower mold 2, fixedly disposed on the worktable 1; a movable upper mold 3, disposed on the upper side of the lower mold 2; a mold groove 201, disposed on the lower mold 2; a stripping template 4, symmetrically disposed on both sides of the mold groove 201; side baffles 401, symmetrically disposed on both sides of the mold groove 201, and the side baffles 401 are fixedly connected to the stripping template 4; and a driving assembly for driving the stripping template 4 to move.

[0023] A gantry frame 101 is fixedly connected to one side of the workbench 1, and a first hydraulic cylinder 301 is symmetrically fixedly connected between the gantry frame 101 and the upper mold 3.

[0024] The drive assembly includes a rotating shaft 402 fixedly mounted on a side baffle 401. The rotating shaft 402 is rotatably connected to the worktable 1. A mounting plate 403 is fixedly connected to one side of the worktable 1. A second hydraulic cylinder 404 is rotatably mounted between the mounting plate 403 and the side baffle 401.

[0025] The channel steel raw material, heated to a suitable temperature, is placed on the lower mold 2. In the preparation state, the second hydraulic cylinder 404 is in the retracted state. At this time, one end of the ejector plate 4 is placed on the upper edge of the mold groove 201 to support the placed channel steel raw material. Then, by controlling the two second hydraulic cylinders 404 to extend simultaneously, the channel steel raw material is placed in the set position. At the same time, the two side baffles 401 position the two ends of the channel steel raw material to center it. Then, the first hydraulic cylinder 301 extends to push the upper mold 3 downward, performing hot extrusion on the channel steel raw material between the upper mold 3 and the lower mold 2, so that the raw material is formed in the mold groove 201. After the hot extrusion is completed, the second hydraulic cylinder 404 is activated and retracts, driving the side baffles 401 to rotate around the rotating shaft 402, which in turn drives the ejector plate 4 to rotate, and the formed channel steel is ejected from the mold groove 201. This realizes automated demolding, greatly improves demolding efficiency, reduces the labor intensity of workers, and facilitates automatic positioning of the channel steel raw material, effectively improving the efficiency of hot extrusion forming of channel steel.

[0026] Example 2: Refer to Figures 1-3 A hot extrusion forming device for processing channel steel is basically the same as that in Example 1, except that an inclinometer 405 is fixedly connected to the side baffle 401.

[0027] In a specific implementation, the inclinometer 405 is used to detect the tilt angle of the side baffle 401. The inclinometer 405 is connected to an external microcomputer, which acquires its tilt data in real time. The microcomputer can then control the second hydraulic cylinders 404 on both sides through the data information, ensuring that the second hydraulic cylinders 404 on both sides operate synchronously, thereby improving the accuracy of positioning the channel steel raw material.

[0028] The axis of the rotating shaft 402 is located below the stripping template 4.

[0029] By placing the rotating shaft 402 downwards, it is possible to ensure that the end of the ejector plate 4 fits snugly against the mold groove 201 while avoiding interference.

[0030] The upper side of the lower mold 2 is provided with a positioning groove 203, and the upper side of the positioning groove 203 is symmetrically provided with positioning chamfers 204. The upper edge of the mold groove 201 is provided with a feeding chamfer 202.

[0031] In a specific implementation, the channel steel material is first supported by the template 4. During the slow rotation, the channel steel material can be positioned front and back by the positioning chamfer 204, and then positioned left and right by the side baffle 401, thereby effectively improving the accuracy of hot extrusion forming of the channel steel.

[0032] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
