Description
Technical Field
The utility model mainly relates to the technical field of granulator device components, in particular to a screw spring piece of a die cover.
Background
A ring die granulator is a machine capable of extruding powdery materials into granules, and is very common in feed production. The die cover and granulator ring die are assembled in full face contact.
The spring plate of the original die pressing cover screw is large in height, and the spring plate needs to be pushed to a clamp spring position with large force. Leading to failure of the spring type variables and damage to the die cover screws.
SUMMERY OF THE UTILITY MODEL
Aiming at the defects in the prior art, the utility model provides a die cover screw spring piece, aiming at ensuring the spring type variable and improving the qualification rate of the die cover screw when the die cover screw is assembled.
The utility model provides a screw spring piece of a pressing die cover, which comprises a backstop gasket 1, a shoulder screw 2, a spring piece 3 and a clamp spring 4;
the spring piece 3 and the backstop gasket 1 are horizontally sleeved on the shoulder screw 2 at one time; the clamp spring 4 is clamped on the shoulder screw 2; the clamp spring 4 is arranged in the retaining gasket 1.
Preferably, the diameter of the spring plate 3 is larger than that of the end of the shoulder screw 2.
Preferably, the diameter of the spring plate 3 is smaller than that of the retaining washer 1.
Preferably, the end of the shoulder screw 2 away from the spring plate 3 is provided with a groove.
Preferably, the end portion of the shoulder screw 2 is chamfered.
Preferably, the groove lead angle is arranged.
The utility model has the beneficial effects that: the assembly difficulty of the die cover screw is reduced, scrappage is reduced, and cost is saved. Meanwhile, the deformation of the spring is ensured, and the service life is prolonged.
