Abstract

The utility model discloses a pin of pin-type cold feed extruder. The pin comprises a pin cap and a pin split-type structure. The utility model has the advantages of convenient installation and disassembly, simple processing technology and low cost, the productivity and the yield of the pin cold feed extruder are greatly increased.

Description

A kind of pin of pin cold feed extruder

Technical field:

The utility model relates to a kind of pin, especially relates to a kind of pin of pin cold feed extruder.

Background technology:

The pin of traditional pin cold feed extruder is a monolithic construction, in the time of in it is installed on machine barrel, in need it being rotated into by the helicitic texture of itself, pass barrel wall and insert in the screw slot until pin, require on the pin helicitic texture must concentric with the location structure of pin and machine barrel (being form and position tolerance accuracy height) like this, cause machining accuracy higher; On the other hand, when pin after use after a while, the pin head that inserts in the screw slot can bend even rupture, so must make regular check on the bending status of pin.As long as find the pin dismounting at need, its head is crooked, brings very big difficulty for like this pin dismantlement work.Therefore, for no other reason than that the pin bending and deformation of head, just need running check and change pin at any time, and whole pin all must change, this has had a strong impact on its serviceability for highly efficient and productive pin cold feed extruder.

The utility model content:

The purpose of this utility model is to provide a kind of pin of novel pin cold feed extruder.

The purpose of this utility model is implemented by following technical scheme: the pin of pin cold feed extruder, described pin main body includes lug cap and the pin body divides body structure.

The utility model has the advantages that: installation, convenient disassembly, the processing technology of pin is simple, and cost reduces, and has improved the production efficiency of pin cold feed extruder greatly, has improved output.

Description of drawings:

Fig. 1 is an overall structure schematic diagram of the present utility model.

Fig. 2 is the structural representation of the utility model pin body.

Fig. 3 is the structural representation of the utility model lug cap.

Fig. 4 inserts the structural representation of pin cold feed extruder for the utility model pin.

Embodiment:

As Fig. 1, Fig. 2, Fig. 3, shown in Figure 4, the pin of pin cold feed extruder, the pin main body includes lug cap 1 and 2 fens body structures of pin body.

During installation, only need the pin body is gone into along the pin hole straight cutting on the barrel wall, insert in the screw slot, then lug cap 1 is screwed on the machine barrel in the pin hole, make its location until contact pin body until the head of pin body.The location structure of pin body is bigger, so qualitative energy is fine, and processing is got up conveniently; In making regular check on, when finding pin body 2 head generation micro-deformations, also can disassemble very easily, and by checking the degree of crook of pin body head: when slightly distortion being arranged, can not influence its normal use yet, can be with its Rotate 180 degree, make its back-flexing, continue to use.Prolong the life cycle of pin like this, reduced the replacing number of times again, improved production efficiency simultaneously; When needs were changed pin, the lug cap of only need outwarding winding can be extracted the pin body, even pin working portion stress deformation is extracted also very convenient; When reusing, lug cap can continue to use, and greatly reduces cost like this.

Claims (1)

1. the pin of a pin cold feed extruder is characterized in that, described pin main body includes lug cap and the pin body divides body structure.
