Description

TECHNICAL FIELD

[0001] The utility model relates to aluminum alloy processing equipment technical field, concretely relates to a hot extruding machine bolt anti -disengagement structure. BACKGROUND

[0002] The aluminum alloy hot extruding machine is a kind of mechanical equipment specially used to heat aluminum alloy material by pressure, to form the required cross-sectional shape in die.The aluminum alloy hot extruding machine is mainly composed of hydraulic system, workbench, storage cylinder, heating system, die and other parts, and the above-mentioned parts work cooperatively to ensure that the aluminum alloy material can be smoothly extruded into the required shape.During the extrusion process, due to the high temperature and high pressure effect on the billet in the die, the internal crystal structure changes, so that the shape of the aluminum alloy at the discharge port matches the shape of the die inner wall.

[0003] Usually, in order to improve the connection reliability of the die and the workbench, a plurality of bolts are arranged between the die and the workbench for fixation.It is found that the bolts at the mutual connection of the die and the workbench will loosen or even disengage during frequent extrusion and shaking, so workers need to tighten the bolts, and the working site is in a high temperature environment, which is labor-intensive and easy to be scalded. CONTENT OF THE UTILITY MODEL

[0004] The utility model intends to provide a hot extruding machine bolt anti-disengagement structure to solve the problem of bolt loosening and disengaging during frequent extrusion and shaking in the prior art.

[0005] In order to solve the above problems, the utility model provides the following technical scheme:

[0006] A hot extruding machine bolt anti-disengagement structure, comprising a workbench and a die, the workbench and the die are fixed by a plurality of bolts;The end surface of the workbench is fixedly provided with a connecting frame, the connecting frame and each bolt are respectively fixedly connected with a first connecting beam, and the adjacent bolts are fixedly connected with a second connecting beam.

[0007] The working principle and beneficial effects of the utility model are as follows:

[0008] In the present application, the workbench is fixed to the ground, a connecting frame is fixedly arranged on the end surface of the workbench, a first connecting beam is fixedly connected between the connecting frame and each bolt, and a second connecting beam is fixedly connected between adjacent bolts, the plurality of bolts and the workbench are connected by the first connecting beam and the second connecting beam, and the plurality of bolts are limited and fixed during the frequent extrusion and shaking of the extruder, so as to prevent the loosening of the bolts.

[0009] The plurality of first connecting beams and second connecting beams limit and fix the bolts, so as to prevent the loosening of the bolts.

[0010] Optimally, the first connecting beams bolted on the left and right sides are obliquely arranged, and the first connecting beams bolted in the middle are vertically arranged. The bolts are fixed at multiple angles by the oblique first connecting beams and the vertical first connecting beams, thereby achieving better anti-loosening effect.

[0011] Optimally, the first connecting beams and the second connecting beams are separated from the workbench. When the equipment needs to be overhauled, the first connecting beams and the second connecting beams are not fixed together with the workbench, thereby facilitating disassembly.

[0012] Optimally, the first connecting beams and the second connecting beams are connected by welding. The welding is more secure.

[0013] Optimally, the connecting frame is a circular frame. The circular frame fixes the bolts at multiple angles to prevent loosening of the bolts.

[0014] Optimally, the heights of the plurality of bolts are different. By fixing at different heights, the fixing effect is better. BRIEF DESCRIPTION OF DRAWINGS
