Description

Technical Field

[0001] This utility model relates to extrusion process equipment, specifically to an auxiliary installation fixture for the extrusion rod of an extruder. Background Technology

[0002] Extrusion presses, as key equipment in the metal processing field, play an irreplaceable role in the production of tubes, bars, and profiles from light alloys such as aluminum, copper, and magnesium. Their working principle is based on metal plastic pressure forming, enabling the processing of metal ingots into the required tubes, bars, and profiles in a very short time—a highly efficient process virtually unmatched by other technologies. Among the many components of an extrusion press, the extrusion bar is one of the core components. It directly contacts the metal billet and applies pressure, pushing the metal to flow within the die, thereby achieving the extrusion forming of the profile. The installation accuracy and stability of the extrusion bar have a crucial impact on the working performance of the extrusion press and the quality of the profiles. Improper installation of the extrusion bar can not only lead to dimensional deviations and reduced surface quality in the profiles but may also cause equipment failure, reduce production efficiency, and increase production costs. Utility Model Content

[0003] To address the aforementioned problems, the purpose of this utility model is to provide an auxiliary installation fixture for the extrusion rod of an extruder.

[0004] According to this utility model, an auxiliary installation fixture for an extrusion press extrusion rod is provided, comprising: an extrusion rod stacking platform with a dovetail groove and fixing holes, and a fixing fixture having a lifting ring, a curved surface, multiple mounting holes, and threaded parts. The dovetail groove extends longitudinally along the extrusion rod stacking platform to form a trapezoidal cavity with an upper opening width smaller than the bottom wall width. The upper opening width corresponds to the diameter of the extrusion rod, and the height of the trapezoidal cavity corresponds to the radius of the extrusion rod. Fixing holes are formed on the top walls of both sides of the upper opening. The curved surface is formed as a semi-circular arc with an inner circumferential surface consistent with the outer circumferential contour of the extrusion rod. The center of the semi-circle coincides with the midpoint of the upper opening of the dovetail groove. The lifting ring and multiple mounting holes are respectively formed on the flanges at both ends of the curved surface. The fixing holes and mounting holes are arranged correspondingly to each other.

[0005] Preferably, the extrusion bar stacking platform and the fixing fixture are respectively formed as left-right symmetrical structures along the axial direction.

[0006] Preferably, the extrusion bar stacking platform is made with a cuboid profile.

[0007] Preferably, as fixing holes, two holes I and II are opened on the left side of the extrusion rod stacking platform, and two holes III and IV, which are symmetrical to the left side, are opened on the right side of the extrusion rod stacking platform.

[0008] Preferably, two parallel upward-extending lifting rings, including a left lifting ring II and a right lifting ring I, are welded to the flanges on both sides of the fixed fixture, respectively, and are perpendicular to the upper surface of the flanges of the fixed fixture.

[0009] Preferably, as mounting holes, two holes V and VI are made on both sides of the left lifting ring II, and two holes VII and VIII, parallel to holes V and VI, are made on both sides of the right lifting ring I.

[0010] The tooling according to this utility model can play a fixing role during installation, preventing it from moving and ensuring the stability of heavy-duty installation operations. In addition, the tooling can reduce the direct handling and adjustment of the extrusion rod by manual labor, thereby reducing the labor intensity of workers.

[0016] <Overall Structure>

[0017] This utility model provides an auxiliary installation fixture for extrusion press extrusion rods, including an extrusion rod stacking platform 100 and a fixing fixture 200.

[0018] Among them, such as Figure 2 , 3 As shown, the extrusion bar stacking platform 100 includes: a dovetail groove 101 and multiple fixing holes, such as hole I 102, hole II 103, hole III 104, and hole IV 105.

[0019] Among them, such as Figure 1 As shown, the fixed fixture 200 includes: a lifting eye section, such as lifting eye I 209 and lifting eye II 211; a curved surface section 210; multiple mounting holes and threaded parts, such as hole V 205, hole VI 206, hole VII 207, hole VIII 208, bolt I 201, bolt II 202, bolt III 203, and bolt IV 204.

[0020] The extrusion bar stacking platform 100 is made into a suitable cuboid profile, and a downwardly recessed dovetail groove 101 is longitudinally cut through the extrusion bar stacking platform 100. Figure 2In the cross-sectional view shown, the dovetail groove 101 has a left-right symmetrical structure, forming a trapezoidal cavity with an upper opening width smaller than the bottom wall width, which is used to accommodate the body of the extrusion press extrusion rod (also referred to as the extrusion rod). Preferably, the upper opening width corresponds to the diameter of the extrusion rod, and the height of the trapezoidal cavity corresponds to the radius of the extrusion rod, that is, the extrusion rod can just fall into the dovetail groove 101 from above the opening. At this time, the axis or center of the extrusion rod coincides with the midpoint of the upper opening width.

[0021] In addition, multiple fixing holes are made on the top walls of both sides of the upper opening. For example, two symmetrical holes I102 and II103 are made on the left side of the extrusion rod stacking platform 100, and two symmetrical holes III104 and IV105 are made on the right side of the extrusion rod stacking platform 100. Holes I102, II103, III104, and IV105 are symmetrical and parallel to each other around the extrusion rod 300, and their axes are perpendicular to the plane of the extrusion rod stacking platform.

[0022] The fixture 200 is made to a suitable size and is generally composed of a curved surface 210 and flanges located symmetrically at both ends. The curved surface 210 is made into a semi-circular arc shape whose inner circumferential surface matches the outer circumferential contour of the extrusion rod 30. The center of the semi-circle coincides with the midpoint of the upper opening of the dovetail groove 101 and the center of the extrusion rod 300 when it is placed. This precise center alignment ensures stability and improves installation efficiency.

[0023] Two parallel, upwardly extending lifting rings are welded to the flanges on both sides of the fixed fixture 200. The lifting rings are perpendicular to the upper surface of the flanges of the fixed fixture 200. Two symmetrically arranged holes V205 and VI206 are made on both sides of the left lifting ring II211. Two holes VII207 and VIII208, parallel to the holes V205 and VI206 on both sides of the right lifting ring I209, are made on both sides of the right lifting ring I209.

[0024] Holes V205, VI206, VII207, and VIII208, drilled on the fixed fixture 200, are symmetrically parallel to each other at the four corners of the fixed fixture 200, and their axes are perpendicular to the bottom plane of the fixed fixture 200. Therefore, the axes of holes I102, II103, III104, and IV105 drilled on the extrusion rod stacking platform 100 correspond to and coincide with the axes of holes V205, VI206, VII207, and VIII208 drilled on the fixed fixture 200.

[0025] <Principles of Movement>

[0026] The extrusion rods 300 are placed in the dovetail grooves 101 of the extrusion rod stacking platform 100. The extrusion rods 300 are in contact with the two side walls of the upper opening of the dovetail groove 101 and with the bottom surface (i.e., the lower plane) of the dovetail groove 101. The fixing fixture 200 is placed on the upper end of the extrusion rod stacking platform 100. Holes V205, VI206, VII207, and VIII208 in the fixing fixture 200 are connected to hole I102 in the extrusion rod stacking platform 100. Holes II 103, III 104, and IV 105 are aligned. At this point, the top walls on both sides of the upper opening of the pressure bar stacking platform 100 are in planar contact with the flanges on both sides of the fixed fixture 200. Bolts corresponding to the holes are used to connect and fix the fixed fixture 200 and the pressure bar stacking platform 100 into a pressure bar auxiliary installation fixture. The overhead crane is used to operate the lifting ring to transfer the auxiliary installation fixture to the pressure bar installation location for installation, ensuring that the installation is carried out smoothly.

[0027] Thus, when the extrusion rod 300 needs to be replaced, the new extrusion rod 300 is placed in the dovetail groove 101 of the extrusion rod stacking platform 100, and the fixing fixture 200 and the extrusion rod stacking platform 100 are connected with bolts to form an auxiliary installation fixture for the extrusion rod. The auxiliary installation fixture is then moved to the installation location by an overhead crane to install the extrusion rod.
