Problems solved by technology

[0005] The present invention aims at the existing ordinary solid tires which are designed to be circular in order to pursue driving speed and stability, so the contact area with the ground is small, and the functions of special vehicles cannot be fully utilized, and the needs of these special terrains cannot be adapted, resulting in some Due to defects such as special driving and operation safety that cannot be effectively guaranteed, a new manufacturing method for polygonal solid tires is provided.

Embodiment 1

[0044] A method for manufacturing a polygonal solid tire, comprising the following steps:

[0045] (1) Take a rubber material A, extrude the rubber material A through an extruder and cut it to form a straight rubber strip;

[0046] (2) Take a rubber material B, extrude the rubber material B through an extruder into a rubber strip with a buffer cooling hole 21 and a triangular cross-section, and cut it to form a convex rubber strip 2;

[0047] (3) Take the pins 6 with the same diameter as the buffer cooling holes 21 and insert each pin 6 into the corresponding buffer cooling holes 21 of the flange strip 2;

[0048] (4) Take at least three chime strips 2 with pins 6 and transfer them to the positioning grooves 41 on the chime strip positioning device 4 ;

[0049] (5) Take the straight rubber strip prepared in step (1) and coil the straight rubber strip along the outer surface of the green tire positioning device 5 to form the main body part 3 of the green tire;

[0050](6) The...

Embodiment 2

[0067] As a preference, the rubber material A in the step (1) and the rubber material B in the step (2) include the following composition by weight:

[0068] rubber 35,

[0069] carbon black 30,

[0070] operating oil 8,

[0071] staple fiber 5,

[0072] Adhesive 3,

[0073] Additive 2;

[0074] The preparation steps are as follows:

[0075] The materials of the above weight components were weighed, and then mixed and put into an internal mixer for mixing, wherein the pressure of the upper ram was 6kgf / cm2, the mixing time was 6 minutes, and the mixing temperature was 120°C. All the other implementation steps are the same as in Example 1.

Embodiment 3

[0077] As a preference, the rubber material A in the step (1) and the rubber material B in the step (2) include the following composition by weight:

Abstract

The invention discloses a method for manufacturing a polygonal solid tire, which comprises the following steps: taking a rubber material A, extruding and cutting to form a straight rubber strip; taking a rubber material B and extruding a rubber strip with buffer cooling holes and a triangular section , cut to form a chisel strip; insert the pin into the buffer cooling hole; take the chisel strip and transfer them to the positioning grooves on the chisel strip positioning device; take the straight strip and place it along the tire The outer surface of the positioning device is coiled to form the main body of the green tire; the positioning drive device is used to push the positioning devices of each rib to move inward so that the rib rubber is bonded to the side surface of the main body of the green tire to form a polygonal tire green; The polygonal tire blank is vulcanized to form a polygonal solid tire with patterns on the surface. The invention increases the contact area between the tire and the ground to improve the grip force of the tire on soft and rugged ground such as deserts, swamps and mountains, so that the safety of special driving and operation is effectively guaranteed.

Description

technical field [0001] The invention relates to the technical field of tire manufacturing, in particular to a method for manufacturing a polygonal solid tire. Background technique [0002] With the progress of society and the need for safety guarantees in production operations, many special vehicles such as engineering vehicles and rescue vehicles used in extremely harsh environments and complex road conditions do not pursue the advantage of driving speed, but pay more attention to the desert. , Swamp, mountain and other soft, rough ground grip and driving safety. At present, although ordinary pneumatic tires have the advantages of shock absorption and comfort, they cannot well adapt to the operation requirements of special terrain. In harsh environments, pneumatic tires are prone to air leakage, tire burst, etc., which limits the safety production in special environments. needs. [0003] As a tire suitable for running vehicles under low-speed, high-load harsh conditions, ...
