Abstract
Description
Technical Field
[0001] The utility model relates to an auxiliary tooling for an aluminum profile extrusion die, in particular to an extrusion die repair workbench, which is used for adjusting the angle and direction of the die during the repair process. Background Art
[0002] Extrusion dies require high-precision processing and repair. During the repair process of the extrusion die, the angle and direction of the die need to be adjusted frequently in order to measure and correct the extrusion die.
[0003] Conventional extrusion dies are mostly cylindrical in shape. The larger the die size, the heavier the die, and the more inconvenient the operation. A medium-sized extrusion die can weigh 50-200 kg, and the die dimensions can reach 450 mm in diameter and 320 mm in thickness.
[0004] In the prior art, vise clamps and simple U-shaped frames are commonly used, which are unsafe and inconvenient, and affect the accuracy of mold repair. Summary of the Invention
[0005] The utility model aims to provide an extrusion die repair workbench so as to adjust and position the angle and direction of the die.
[0006] In order to achieve the above-mentioned purpose, the technical solution adopted by the utility model is: an extrusion die repair workbench, comprising:
[0007] a base;
[0008] A rotating table, which is rotatable around a vertical line and is arranged on the base;
[0009] A rotation positioning mechanism for positioning the rotation angle of the rotating table relative to the base;
[0010] Two rollers are supported horizontally on the rotating table in parallel.
[0011] A clamping mechanism is provided between the two rollers and comprises a fixed abutting surface, a translational clamping surface, and a driving mechanism for driving the translational clamping surface toward the fixed abutting surface; the direction of the line connecting the fixed abutting surface and the translational clamping surface is parallel to the axial direction of the rollers;
[0012] When in use, the axes of the two rollers are in contact with and supported on the bottom of the extrusion die. The clamping mechanism is used to clamp and position the extrusion die in the axial direction. The rotation positioning mechanism positions the rotating table relative to the base.
[0013] In the above scheme, a front baffle and a rear baffle are set on the rotating table, and two rollers are mounted between the front baffle and the rear baffle; the inner side surface of the front baffle or the rear baffle serves as the fixed abutment surface, and a fastening plate is connected to the fixed abutment surface for translational sliding on the rotating table, and the side of the fastening plate facing the fixed abutment surface serves as the translational clamping surface.
[0014] Furthermore, the front and rear baffles each extend upwardly, with the top surface of the extension higher than the highest point of the roller shaft, serving as a protective section. Furthermore, the front and rear baffles each have an arc-shaped avoidance groove recessed in the middle of their top surfaces. Furthermore, the rotating table also includes left and right baffles, which are positioned outside the two roller shafts and connected between the front and rear baffles. The top surfaces of the left and right baffles are higher than the highest point of the roller shaft, serving as a protective section.
[0015] In the above scheme, the driving mechanism is a screw-nut mechanism, in which the screw is rotatably mounted between the front baffle and the rear baffle and located between the two roller shafts, the end of the screw extends out and is connected to a hand-cranked operating part, and the nut in the screw-nut mechanism is fixedly connected to the fastening plate.
[0016] The effects of the utility model are:
[0017] This utility model cleverly features two rollers. During use, the user can place the outer cylindrical surface of the extrusion die on the two rollers. By manually rotating the extrusion die in the direction of its end face, the die can be easily rotated about its axis. Once fully rotated, the drive mechanism can be operated to clamp the die in place. Furthermore, because the two rollers of this utility model are located on a rotating table, the user can adjust the horizontal angle of the extrusion die by gently rotating the table. Once the die is in the desired position, the rotation positioning mechanism can be used to position the die in that position. This utility model easily achieves adjustment and positioning of the extrusion die in two degrees of freedom: axial rotation and end face rotation, making it convenient for trimming the extrusion die.

[0023] The present invention will be further described below with reference to the accompanying drawings and embodiments:
[0024] Example: See Figure 1-4 As shown,
[0025] A workbench for repairing an extrusion die comprises a base 1, a rotating table 2, a rotating positioning mechanism 3, two rollers 4 and a clamping mechanism 5.
[0026] The rotating table 2 is rotatable around a vertical direction and is arranged on the base 1 .
[0027] The rotation positioning mechanism 3 is used to determine the rotation angle of the rotating table 2 relative to the base 1. Specifically, the rotation positioning mechanism 3 can be a screw-holding mechanism. Specifically, a screw hole is provided in the base 1 along the radial direction of the rotating shaft of the rotating table 2. A screw is installed in the screw hole, and the tail end of the screw presses against the outer circumferential surface of the rotating shaft of the rotating table 2 to achieve the positioning effect. Of course, in practice, the rotation positioning mechanism 3 can also adopt other locking mechanisms as long as it can lock the rotating table 2.
[0028] The two rollers 4 are supported on the rotating table in parallel in the horizontal direction.
[0029] The clamping mechanism 5 is disposed between the two rollers 4 and comprises a fixed abutment surface 51, a translational clamping surface 52, and a driving mechanism for driving the translational clamping surface 52 toward the fixed abutment surface 51. The line connecting the fixed abutment surface 51 and the translational clamping surface 52 is parallel to the axial direction of the roller 4.
[0030] When in use, the two rollers 4 are supported in line contact at the bottom of the extrusion die 6 , the clamping mechanism 5 is used to clamp and position the extrusion die 6 in the axial direction, and the rotation positioning mechanism 3 positions the rotating table 2 relative to the base 1 .
[0031] A front baffle 21 and a rear baffle 22 are provided on the rotating table 2, and two rollers 4 are mounted between the front baffle (21) and the rear baffle 22. The inner side surface of the front baffle 21 or the rear baffle 22 serves as the fixed abutment surface 51, and a fastening plate 53 is connected to the fixed abutment surface 51 in translational sliding on the rotating table 2. The side surface of the fastening plate 53 facing the fixed abutment surface 51 serves as the translational clamping surface 52.
[0032] The front baffle 21 and the rear baffle 22 extend upwards to form an extension section, so that the top surface of the extension section is higher than the highest position of the roller shaft as a protection section. The top surfaces of the front baffle 21 and the rear baffle 22 are concavely provided with arc-shaped avoidance grooves 211 and 221 in the middle.
[0033] The rotating table 2 is also provided with a left baffle 23 and a right baffle 24, which are respectively arranged on the outside of the two roller shafts 4 and connected between the front baffle 21 and the rear baffle 22; the top surfaces of the left baffle 23 and the right baffle 24 are higher than the highest position of the roller shaft 4 to serve as a protective section.
[0034] The protective sections on the front baffle 21 and the rear baffle 22 and the protective sections on the left baffle 23 and the right baffle 24 are used to protect the extrusion die 6 to prevent the extrusion die 6 from falling from the workbench and causing safety problems.
[0035] The drive mechanism specifically employs a screw-nut mechanism 54. The screw in the screw-nut mechanism 54 is rotatably mounted between the front baffle 21 and the rear baffle 22 and located between the two roller shafts 4. The end of the screw extends and connects to a hand-cranked operating portion 55, while the nut in the screw-nut mechanism 54 is fixedly connected to the fastening plate 53. In practice, other drive mechanisms may also be employed, as long as they can drive the fastening plate 53 to translate, such as a gear rack.
[0036] During use, the user places the outer cylindrical surface of the extrusion die 6 on the two rollers 4. Manually rotating the extrusion die 6 in the direction of its end face allows the die 6 to be easily rotated about its axis. Once fully rotated, the clamping mechanism 5 can be operated by the drive mechanism to clamp and secure the die 6. Furthermore, because the two rollers 4 are mounted on a rotating table, the user can adjust the horizontal angle of the extrusion die 6 by gently rotating the rotating table 2. Once the die 6 reaches the desired position, the positioning mechanism 3 can be used to position the die at that position. This embodiment easily achieves adjustment and positioning of the extrusion die 6 in both axial and end face rotation, facilitating trimming of the die 6.
[0037] The above embodiments are intended only to illustrate the technical concepts and features of the present invention. Their purpose is to enable those familiar with the art to understand the contents of the present invention and implement them accordingly. They are not intended to limit the scope of protection of the present invention. Any equivalent changes or modifications based on the spirit of the present invention are intended to be included in the scope of protection of the present invention.
