Description

Automatic dismounting tool for machine barrel flange fixed connecting bolt

Technical Field

The utility model belongs to the technical field of fastener dismounting devices, and particularly relates to an automatic dismounting tool for a machine barrel flange fixing connecting bolt.

Background

The above-mentioned barrel flange mainly refers to a barrel flange of a barrel of a plastic extruder for extrusion-molded pipes. Of course, since the connection of the head to the barrel is also by means of a head flange formed on the head to a barrel flange formed on the barrel, the aforementioned barrel flange securing bolts also include essentially the head flange and barrel flange securing bolts.

As is known in the art, plastic extruders are typically composed of an extrusion system, a drive train, a heating and cooling system, and the like. The extrusion system mainly comprises a screw, a machine barrel, a hopper, a machine head and a die, wherein plastic is plasticized into a melt through the system, and then is continuously extruded to the machine head by the screw. Screws are the main component of plastic extruders and are typically made of high strength corrosion resistant alloy steel. The barrels are typically made of metal such as stainless steel or composite steel tubing. The plastic is crushed, softened, melted, plasticized, exhausted and compacted through the double matching of the machine barrel and the screw. Since the common plastic pipe extruder is a well-known technique and can be found in the published chinese patent literature, such as CN211566886U (an extruder for producing plastic pipes), CN214926925U (a plastic pipe extruder), CN208576172U (a plastic pipe extruder) and CN207617067U (a plastic pipe extruder), etc., the applicant will not be described in detail.

As known in the art, it is generally necessary to clean the aforementioned barrels in two cases, not limited to the illustrative cases, firstly, after a period of time or a period of use, there is a residual scaling condition in the barrel and the scaling adheres more and more tenaciously to the inner wall of the barrel over time, which seriously damages the equipment and affects the quality of the product, so that it is necessary to clean the barrel with regular or irregular maintenance (the same example of the handpiece); secondly, when the raw materials are replaced, the machine barrel and the machine head need to be cleaned before the raw materials are replaced. When the machine barrel and/or the machine head are to be cleaned, the machine barrel connecting flange needs to be detached, namely the machine barrel flange connecting bolts fixedly connected to two adjacent machine barrel flanges are detached, then cleaning is carried out, and after the cleaning is finished, the machine barrel flange connecting bolts are returned to be installed, namely the machine barrel flange connecting bolts are screwed. Since the connection part of the machine barrel and the machine head is basically also in flange connection, when the machine head of the extruder is to be replaced, the flange connected between the machine head and the machine barrel is also required to be disassembled, namely, the flange connection bolt of the machine barrel of the machine head is required to be disassembled. Since the above-described mounting and dismounting modes are identical, only the barrel flange coupling bolts will be described below.

The prior art for the disassembly and assembly of the aforementioned barrel flange bolts is generally operated manually, in particular, by a worker who removes or installs the barrel flange bolts one by means of a tool such as a wrench, which is deficient in that: the operation efficiency is low; the bolt disassembly and assembly operation intensity of an operator is high; since the barrel flange connection bolts of the plastic extruder are generally provided with a group of barrel flange connection bolts which are distributed at intervals around the circumferential direction, especially the larger the specification such as the diameter of a plastic pipe is, the diameter of the barrel is correspondingly increased, the number of the barrel flange connection bolts is correspondingly increased, and due to manual installation, the consistency of the fastening degree of all the barrel flange connection bolts is difficult to ensure, the unbalance of the tightness or the tightness of the barrel is often generated, the installation quality of the barrel is affected, and the product quality is also affected to a certain extent.

Chinese patent publication No. CN207026924U discloses a "semi-automatic flange bolt synchronous fastening and dismounting device", which is effective for the synchronous fastening and dismounting of flange bolts between two flanges connected in a vertically corresponding relationship, but because of lack of a mechanism for reliably clamping a workpiece with flanges at the ends, such as a pipe body or a shaft body, the fastening and dismounting of the flange bolts in a lying part may be in the form of amour, thereby exposing the patent to the picking in practical use. More specifically, the patent does not satisfy the requirements for the disassembly and assembly of the barrel flange connection bolts of the plastic extruder in the horizontal position.

When the motor force spring 77 is no longer compressed, i.e., compressed to a limited extent, it indicates that the barrel flange bolt removal wrench 79 has completed removal (or disassembly) of the barrel flange attachment bolts 2011.

The applicant will not be reiterated since the disassembly and assembly of the head flange of the head and the barrel flange 20 of the barrel are as described above.

The nose flange is identical to barrel flange 20.

The applicant needs to say that: the flange connection bolt 2011 of the machine barrel can be disassembled and assembled only by the structure of the utility model shown in fig. 1, and the front and rear semicircular rings 2 and 3 are only required to be supported by an operator by hands so as to avoid tilting leftwards or rightwards.

Preferably, the barrel flange bolt removal wrench 79 is magnetically configured to capture the barrel flange attachment bolts 2011 removed from the barrel flange 201. Preferably, since the barrel flange bolt attaching/detaching wrench 79 exemplified in the present embodiment is a male wrench, it is completely replaced with a female wrench, and when replaced with a female wrench, a wrench inner hexagonal hole is formed thereon so as to be matched with the outer hexagonal head of the barrel flange connecting bolt 2011. Since the installation process of the barrel flange connection bolt 2011 is the same as that described above, only the wrench driving motor 78 is operated reversely, and thus the applicant will not be reiterated.

In summary, the technical scheme provided by the utility model overcomes the defects in the prior art, successfully completes the task of the utility model, and faithfully honors the technical effects carried by the applicant in the technical effect column above.
