Embodiment Construction

[0029] Such as figure 1 As shown, the present invention mainly includes: pressing shaft 2, guide sleeve 3, fixed base 4, etc., this extrusion test device is connected on the press machine 1, and press machine 1 is the use platform of extrusion test device, and this platform provides A pressure machine interface 1-1 driven by the press machine 1 to move up and down at an adjustable speed, which realizes fixing the pressing shaft 2 on the interface 1-1 of the press machine 1 through a round nut 2-3 and a stop pin 2-2, Such as figure 2 shown. Then the stop pin 2-2 is screwed and fixed on the press interface 1-1 through the nut 2-1. Its working principle is: put the pressing shaft 2 into the interface 1-1, and then put it into the stop pin 2-2. The stop pin 2-2 does not provide any matching size, and its function is to prevent the pressing shaft 2-4 from falling. Finally, the locking of the pressing shaft 2 is realized by tightening the nut 2-1.

Abstract

The invention discloses an extrusion test device. The device comprises a pressing shaft, a guiding sleeve and a fixing pedestal. The upper end of the pressing shaft is fixedly connected to a press machine interface which is driven by a press machine so that a speed can be adjusted and can move up and down. The guiding sleeve is a hollow barrel which can accommodate the pressing shaft to carry outvertical up-and-down movement. The lower end of the guiding sleeve possesses an edge which is protruded from the barrel. The fixing pedestal comprises an annular sleeve installation seat and a supportrod. The sleeve installation seat is supported by the support rod. The middle portion of the sleeve installation seat forms one installation hole possessing a shoulder. The lower portion of the installation hole is used for accommodating a template. The upper portion of the installation hole correspondingly accommodates the edge of the guiding sleeve. The structure is simple, cost is low, the operation efficiency of a test is increased and the cost of an extrusion test is reduced.

Description

technical field [0001] The invention relates to an extrusion test device, in particular to a simulated extrusion device for granulation equipment in the field of feed processing. Background technique [0002] The particle forming experiment of the existing granulator is generally carried out with a small granulator, such as Figure 8 As shown, by changing the hole diameter of the ring die and the compression ratio to carry out the extrusion experiment on the material, the parameters of the ring die that meet the particle quality requirements are optimized. Although the convenience of the small test machine has been improved, the traditional ring die, The structure of the pressure roller 100, long-term use will cause the problem of wear of the pressure roller; the structure of the door opening 200 is not convenient for external observation, the bolts are tightened to close the door, and the operation is cumbersome. On the whole, there are still problems such as long experiment...
