[0002] As the core component of the extrusion machine, the barrel of the extrusion machine plays a very important role. One of the development trends of today's large-scale extrusion machines is: the capacity of a single machine is gradually increasing, and the specifications of the unit are getting larger and larger. Large, the original barrel structure is no longer suitable for the needs of large-capacity units in terms of shape, weight, heat transfer capacity and structure, and it is necessary to develop a barrel with a new structure

Embodiment Construction
[0017] Such as Figure 1-4 As shown, the present invention is a ferrule-type machine barrel, including a barrel body 1, which is an integral structure, ferrules 2 are installed on the flange end faces at both ends of the barrel body 1, and the machine barrel The outer periphery of the flange end surface of the barrel body 1 is placed in the groove 23 of the ferrule 2 .
[0018] Because the machine barrel is long, it can be connected as a whole by the multi-section machine barrel body 1 and then connected with the machine barrel connecting sleeve and the throttle opening valve on both sides of the machine barrel, so the connected parts connected with the machine barrel body 1 can be the machine barrel body 1 or barrel connecting sleeve or throttle opening valve.
[0019] When in use, the flange end face of the barrel body 1 and the outer circumference of the flange end face of the connected parts are placed in the groove 23 of the same ferrule 2, and the two facades of the gro...

The invention discloses a clamping sleeve type machine cylinder. The clamping sleeve type machine cylinder comprises a machine cylinder body, clamping sleeves are installed on flange end faces at thetwo ends of the machine cylinder body, and the outer periphery of the flange end surface of the barrel body is arranged in grooves of the clamping sleeve. The clamping sleeve type machine cylinder hasthe advantages that the structure is simple, the connecting mode is changed into a clamping sleeve form by the flange form, the distance between the inner 8-shaped hole and the outer surface is reduced, the size and the weight of the machine barrel are 20% smaller than that of the machine barrel with the same specification, the cost of raw materials can be greatly reduced, the forging difficultyis reduced, the machining amount is reduced, and meanwhile, machining and assembling of the machine barrel are facilitated; and the clamping sleeve and the machine barrel form a self-locking surface by inclined planes with certain angles, the clamping sleeve is tightly pressed against the inclined surface of the machine barrel through a stud, and compared with a flange type machine cylinder, the connecting strength and the reliability are greatly improved; the inner temperature control flow channel of the inner flow channel of the machine cylinder is a radial flow channel, the consistency of the temperature of the machine cylinder in the Y direction can be ensured, and the process temperature control during material processing can be facilitated.
Description
technical field [0001] The invention relates to an extruder barrel, in particular to a ferrule-type barrel. Background technique [0002] As the core component of the extrusion machine, the barrel of the extrusion machine plays a very important role. One of the development trends of today's large-scale extrusion machines is: the capacity of a single machine is gradually increasing, and the specifications of the unit are getting larger and larger. Large, the original barrel structure is no longer suitable for the needs of large-capacity units in terms of shape, weight, heat transfer capacity and structure, and it is necessary to develop a barrel with a new structure. Contents of the invention [0003] The purpose of the present invention is to overcome the above disadvantages and provide a ferrule-type barrel with relatively small shape and weight, strong heat exchange capacity, accurate positioning and convenient installation. [0004] The technical scheme adopted by the ...
