Technical Field
[0001] The present invention relates to the technical field of crawler track production technology, and more specifically, to a production method of an embedded anti-digging iron tooth crawler track. Background Art
[0002] Iron tooth rubber tracks are tracks made of rubber and skeleton materials. They are widely used in engineering machinery, agricultural machinery and military equipment. Compared with metal tracks, rubber tracks are cheaper and are widely used in small equipment. The rubber tracks move under the drive of gears, thereby driving the equipment to move. Generally, when processing iron tooth rubber tracks, injection vulcanization is generally used for production and processing, that is, by placing iron teeth into a vulcanized mold and then performing injection vulcanization, the bonding strength between the iron teeth and rubber is made higher.
[0003] At present, the iron tooth tracks on the market generally use the above-mentioned process to place the iron teeth into a vulcanization mold to form the iron tooth tracks. However, we found during use that relying solely on the combination between the iron teeth and the rubber cannot effectively solve the problem of the iron teeth detaching. That is, the iron teeth are dug out of the rubber under high pressure, resulting in the scrapping of the iron tooth track. So how to solve the above problem and optimize the production process is our current problem. Summary of the Invention
[0004] In view of the shortcomings of the existing technology, the purpose of the present invention is to provide a method for producing an embedded anti-digging iron tooth track by connecting each iron tooth with a metal wire and forming a vulcanized iron tooth track through injection vulcanization, thereby ensuring that the iron tooth track can form an integral whole between each iron tooth when under pressure, thereby dispersing the force when under pressure and forming an anti-digging effect.
[0005] To achieve the above object, the present invention provides the following technical solution: a method for producing an embedded anti-digging iron tooth track, specifically comprising the following steps: S1, a preparatory stage: track iron teeth, rubber, metal wire and a track forming mold;
[0006] S2. Pretreatment of the teeth: After the main body of the teeth is formed, it needs to be surface treated. First, the machined teeth are cleaned, then dried and the surface debris is cleaned.
[0007] S3. Position adjustment: Place the pre-treated iron toothed belt in step S2 vertically with the toothed surface facing downward on the installation station, waiting for the installation of the metal wire;
[0008] S4. Wire placement: Place the wire on one side of the flat surface at the bottom of the iron tooth and initially secure it with the locking structure.
[0009] S5, initial vulcanization treatment: The iron teeth and metal wire assembly, which have been initially fixed in step S4, are placed in a track forming mold, and the molten rubber is placed into the track manufacturing mold through injection vulcanization for initial vulcanization.
[0010] S6. Pressure maintenance: by setting the pressure value in the crawler forming mold, the pressure value is controlled between 10MPa and 20MPa, and then wait for it to cool down after completion;
[0011] S7, secondary vulcanization treatment: expand the vulcanization range to the target size of the crawler track, perform secondary vulcanization on the crawler track semi-finished product after the preliminary vulcanization operation in step S5, and obtain the finished crawler track after cooling.
[0012] The present invention is further configured such that: step S4 further includes a pre-treatment of the metal wire by impregnating the metal wire with a resin, specifically comprising the following steps: storing the molten resin in an impregnation tank, pulling the metal wire through the impregnation tank by a pulling device, and controlling the viscosity of the resin so that the resin can adhere to the metal wire;
[0013] As the wire is pulled by the traction equipment, it passes through the resin and leaves the dipping tank. The resin is adhered to the wire by drying or air drying. The temperature of water cooling or air cooling is controlled between 50℃ and 60℃.
[0014] After the rubber is attached and the metal wire cools down, the metal wires are tightened and brought closer together by a pulling device, and placed on one side of the plane at the bottom of the iron tooth, waiting for the locking structure to initially fix the metal wires.
[0015] The present invention is further configured as follows: the locking structure includes two side brackets arranged along the width direction of the iron tooth and a push rod connecting the two side brackets in sequence, and the push rod contacts each of the metal wires and fixes each metal wire to the bottom of the iron tooth.
[0016] The present invention is further configured as follows: the step S5 further includes a pressure vulcanization process, and the specific steps of the pressure vulcanization process are as follows:
[0017] S50, during the first time period, as the molten rubber enters the cavity, the cavity pressure will continue to increase until the cavity pressure stops increasing, at which point the cavity pressure is recorded as P1;
[0018] S51, after determining that the pressure in the cavity no longer increases, introducing pressurized gas into the cavity of the crawler forming mold, wherein the gas is an inert gas;
[0019] S52. During the second time period, pressurized gas is introduced into the mold cavity. The pressurized gas is introduced in a multi-section pressurization manner. The specific structure is as follows: the multi-section pressurization structure includes a first throttle chamber directly connected to the mold cavity and a second throttle chamber connected to the first throttle chamber. A pressurization piston is provided between the second throttle chamber and the first throttle chamber. The pressurization piston is movably and sealedly provided between the first and second throttle chambers. The pressurization piston pushes the first throttle chamber to apply pressure via a pressure pushing device. The initial air pressure in the second throttle chamber is recorded as P2, and a pressure is maintained. That is, when the air pressure in the second throttle chamber reaches P2, the pressure is no longer increased.
[0020] S53. In the third time period, after the third time period of the pressurization operation, monitor the air pressure changes in the second throttle chamber and record it as P3, and judge the size between P3 and P2. If the P3 value is less than the P2 value, it is judged that there is still an unfilled area in the cavity, then it is necessary to perform a second pressurization on the second throttle chamber and repeat this step.
[0021] The present invention is further configured as follows: the pressurized vulcanization treatment also includes step S54. In the fourth time period, after the pressurization operation of step S53, the air pressure changes in the two throttle chambers are monitored and recorded as P4. The size between P4 and P2 is judged. If the P4 value is still smaller than the P2 value, it is judged that there is still an unfilled area in the cavity, then it is necessary to perform alternating vacuuming and pressurizing operations on the first throttle chamber for a time of t1. After completion, the pressurization is continued for a time of t2 to complete the pressurized vulcanization operation.
[0022] By adopting the above technical solution, the beneficial effects are as follows: 1. In the technical solution of the present invention, by adding metal wire, after vulcanization, the metal wire forms high adhesion between the iron teeth and the rubber, so that the track still has good anti-digging performance for the iron teeth under high pressure. For this, the present application also uses two vulcanization treatments to form multiple coating effects on the iron tooth structure, and adopts multiple injection vulcanization, which greatly improves the vulcanization effect, and can also improve the bonding strength after vulcanization through two injection vulcanization treatments;
[0023] 2. Step S4 also includes the pre-treatment of the metal wire with impregnation resin coating. The resin coating treatment can make the metal wire and the rubber have good bonding strength. The resin is used as a medium to form a coating layer on the outside of the metal wire, which indirectly improves the bonding between the metal wire and the rubber. Specifically, it includes the following steps: the resin in a molten state is stored in the impregnation tank, the metal wire is pulled through the impregnation tank by a pulling device, and the viscosity of the resin is controlled so that it can adhere to the metal wire; as the pulling device pulls the metal wire through the resin and leaves the impregnation tank, the metal wire is pulled through the resin and leaves the impregnation tank. The resin is attached to the metal wire by drying or air-drying in the immersion pool. The water-cooling or air-cooling temperature is controlled between 50℃ and 60℃. After the rubber is attached and the metal wire cools down, the metal wires are tightened by the traction equipment and placed on the flat side of the bottom of the iron tooth. The metal wires are initially fixed by the locking structure. The above process can form a good coating effect on the metal wire in the immersion pool, thereby forming an intermediate medium on the metal wire, so that a good bonding effect is formed between the metal wire and the rubber, and the practicality is greatly improved.
[0024] 3. The present application also adds a pressure vulcanization treatment in step S5. The pressure vulcanization treatment is actually to perform a preliminary vulcanization treatment before the vulcanization treatment. The scope of this vulcanization treatment is small, but it is to enable the preliminary vulcanization to cover some small spaces with pressure vulcanization. For example, the gap between two adjacent metal wires can be covered by pressure, so that the metal wires can be better preliminarily vulcanized and a strong degree of integration is formed between the metal wires, so that when the secondary vulcanization is performed, the full coverage effect of the secondary vulcanization is ensured, which greatly improves the integrity and practicality.

[0030] Reference Figures 1 to 4 The following is a further description of an embodiment of a method for producing an embedded anti-digging iron tooth track according to the present invention.

[0032] Moreover, relational terms such as “first” and “second” are merely used to distinguish one component from another having the same name, but do not necessarily require or imply any actual relationship or order between these components.
[0033] A method for producing an embedded anti-digging iron tooth 2 crawler track, specifically comprising the following steps: S1, a preparatory stage: crawler iron teeth 2, rubber, metal wire 3 and a crawler forming mold;
[0034] S2. Pretreatment of the iron teeth 2: After the main body of the iron teeth 2 is formed, it needs to be surface treated. First, the machined iron teeth 2 are cleaned, then the cleaned iron teeth 2 are dried and the surface debris is cleaned;
[0035] S3, position adjustment: Place the iron tooth 2 pre-treated in step S2 vertically with the tooth surface facing downward on the installation station, waiting for the installation of the metal wire 3;
[0036] S4, placing the metal wire 3: placing the metal wire 3 on one side of the plane at the bottom of the iron tooth 2, and preliminarily fixing the metal wire 3 by means of a locking structure;
[0037] S5, initial vulcanization treatment: The iron teeth 2 and metal wire 3 assembly, which have been initially fixed in step S4, are placed in a track forming mold, and the molten rubber is placed into the track manufacturing mold by injection vulcanization for initial vulcanization.
[0038] S6. Pressure maintenance: by setting the pressure value in the crawler forming mold, the pressure value is controlled between 10MPa and 20MPa, and then wait for it to cool down after completion;
[0039] S7, secondary vulcanization treatment: expand the vulcanization range to the target size of the crawler track, perform secondary vulcanization on the crawler track semi-finished product after the preliminary vulcanization operation in step S5, and obtain the finished crawler track after cooling.
[0040] In the technical solution of the present invention, a metal wire 3 is added. After vulcanization, the metal wire 3 allows high adhesion between the iron teeth 2 and the rubber, so that the track still has good anti-digging performance on the iron teeth 2 under high pressure. For this reason, the present application also uses two vulcanization treatments to form multiple coating effects on the iron teeth 2 structure, and adopts divided injection vulcanization to greatly improve the vulcanization effect. It can also improve the bonding strength after vulcanization through two injection vulcanization operations. For the two vulcanization operations, the initially vulcanized part is vulcanized again by maintaining pressure, which achieves the stabilization of the primary vulcanized rubber coating, thereby improving the subsequent vulcanization effect and providing a guarantee.
[0041] Furthermore, step S4 also includes a pre-treatment of impregnating the metal wire 3 with a resin, specifically including the following steps: storing the molten resin in an impregnation tank, pulling the metal wire 3 through the impregnation tank by a pulling device, and controlling the viscosity of the resin so that it can adhere to the metal wire 3;
[0042] As the traction equipment pulls the metal wire 3 through the resin and leaves the dipping tank, it is dried or air-dried so that the resin can adhere to the metal wire 3. The water-cooling or air-cooling temperature is controlled between 50°C and 60°C.
[0043] After the metal wire 3 is cooled after being attached to the rubber, the metal wires 3 are tightened together by traction equipment and placed on the flat side of the bottom of the iron tooth 2, waiting for the metal wire 3 to be initially fixed by the locking structure. In the technical solution of the present invention, the metal wire 3 is added. After vulcanization, the metal wire 3 allows high adhesion between the iron tooth 2 and the rubber, so that the track still has good anti-digging performance for the iron tooth 2 under high pressure. For this purpose, the present application also uses two vulcanization treatments to form multiple coating effects on the iron tooth 2 structure, and adopts multiple injection vulcanization, which greatly improves the vulcanization effect, and can also improve the bonding strength after vulcanization through two injection vulcanization treatments.
[0044] Furthermore, the resin wrapping process can ensure good bonding strength between the metal wire 3 and the rubber. The resin is used as a medium to form a coating layer on the outside of the metal wire 3, which indirectly improves the bonding between the metal wire 3 and the rubber. The prepared molten resin is stored in an immersion tank, and the metal wire 3 is pulled through the immersion tank by a traction device. The viscosity of the resin is controlled so that it can adhere to the metal wire 3; as the traction device pulls the metal wire 3 through the resin and leaves the immersion tank, the resin is attached to the metal wire 3 by drying or air drying, and the temperature of water cooling or air cooling is controlled between 50°C and 60°C; after the rubber is attached and the metal wire 3 is cooled, the metal wires 3 are tightened by the traction device and placed on one side of the plane at the bottom of the iron tooth 2, waiting for the metal wire 3 to be initially fixed by the locking structure. The above process can form a good coating effect on the metal wire 3 in the immersion tank, thereby forming an intermediate medium on the metal wire 3, so that a good bonding effect is formed between the metal wire 3 and the rubber, and the practicality is greatly improved.
[0045] Furthermore, the locking structure includes two side brackets 4 arranged along the width direction of the iron tooth 2 and a push rod 5 connected to the two side brackets 4 in sequence. The push rod 5 interferes with each of the metal wires 3 and fixes each metal wire 3 to the bottom of the iron tooth 2. By setting the locking structure as the above structure, the cooperation between the two side brackets 4 and the push rod 5 can provide a fitting effect between the metal wire 3 and the bottom of the iron tooth 2, greatly improving the anti-digging effect provided by the metal wire 3 to the iron tooth 2, making the integration between the metal wire 3 and the iron tooth 2 stronger, and greatly improving the practicality.
[0046] Furthermore, step S5 also includes pressure vulcanization treatment, and the specific steps of the pressure vulcanization treatment are as follows:
[0047] S50, during the first time period, as the molten rubber enters the cavity, the cavity pressure will continue to increase until the cavity pressure stops increasing, at which point the cavity pressure is recorded as P1;
[0048] S51, after determining that the pressure in the cavity no longer increases, introducing pressurized gas into the cavity of the crawler forming mold, wherein the gas is an inert gas;
[0049] S52. During the second time period, pressurized gas is introduced into the mold cavity. The pressurized gas is introduced in a multi-section pressurization manner. The specific structure is as follows: the multi-section pressurization structure includes a first throttle chamber 6 directly connected to the mold cavity and a second throttle chamber 7 connected to the first throttle chamber 6. The first throttle chamber 6 is equipped with an air inlet for filling inert gas. A pressurization piston 8 is provided between the second throttle chamber 7 and the first throttle chamber 6. The pressurization piston 8 is movably and sealedly provided between the first throttle chamber 6 and the second throttle chamber 7. The pressurization piston 8 pushes the first throttle chamber 6 to apply pressure through the pressure pushing device 9. The initial air pressure in the second throttle chamber 7 is recorded as P2, and a pressure is maintained. That is, when the air pressure in the second throttle chamber 7 reaches P2, the pressure is no longer increased.
[0050] S53. In the third time period, after the third time period of the pressurization operation, monitor the air pressure changes in the second throttle chamber 7 and record it as P3. Judge the size between P3 and P2. If the P3 value is smaller than the P2 value, it is judged that there is still an unfilled area in the cavity, then it is necessary to perform a second pressurization on the second throttle chamber 7 and repeat this step.
[0051] The main principles of the multi-section pressurizing structure of the present application are described as follows: the first throttle chamber 6 is connected to the mold cavity, so the air pressure in the first throttle chamber 6 will change due to the flow conditions of vulcanization, especially in some narrow spaces, which will be filled with flow through injection. Then, when the air pressure in the mold cavity decreases, the air pressure in the first throttle chamber 6 will also decrease. In addition, because the air pressure in the second throttle chamber 7 remains constant, if the air pressure in the first throttle chamber 6 decreases, the pressurizing piston 8 provided between the first throttle chamber 6 and the second throttle chamber 7 will also move toward the side of the first throttle chamber 6, and the air pressure in the second throttle chamber 7 will decrease. Therefore, as long as the air pressure in the second throttle chamber 7 is detected, the vulcanization conditions in the chamber can be controlled.
[0052] The present application also adds a pressure vulcanization treatment in step S5. The pressure vulcanization treatment is actually to perform a preliminary vulcanization treatment before the vulcanization treatment. The scope of this vulcanization treatment is small, but it is to enable the preliminary vulcanization to cover some small spaces with pressure vulcanization. For example, the gap between two adjacent metal wires 3 can be covered by pressure, so that the metal wires 3 can be better preliminarily vulcanized and a strong degree of integration can be formed between the metal wires 3, so that when the secondary vulcanization is performed, the full coverage effect of the secondary vulcanization is ensured, the integrity is greatly improved, and the practicality is greatly improved.
[0053] Furthermore, the pressurized vulcanization treatment also includes step S54. In the fourth time period, after the pressurization operation of step S53, the air pressure change in the second throttle chamber 7 is monitored and recorded as P4. The size between P4 and P2 is judged. If the P4 value is still smaller than the P2 value, it is judged that there is still an unfilled area in the cavity, then it is necessary to perform alternating vacuuming and pressurizing operations on the first throttle chamber 6, and the time is t1. After completion, the pressurization is continued for a time of t2, thereby completing the pressurized vulcanization operation.
[0054] In order to make the pressure vulcanization more uniform and cover a larger area, repeated vacuuming and pressure application are performed to form alternating operations, thereby improving the pressure-applied preliminary vulcanization treatment to form all-round preliminary vulcanization, increasing the vulcanization range, and improving the bonding strength of the secondary vulcanization after vulcanization, so that the metal wire 3 can form a good molding effect with the rubber, and achieve a good injection vulcanization effect, so that the metal wire 3, the iron tooth 2 and the rubber have a strong bonding strength, which greatly improves the barrier formed by the metal wire 3 on the iron tooth 2 and the anti-digging effect, greatly improves the practicality, and is also easy to promote.
[0055] The anti-digging iron tooth 2 crawler obtained according to the above production method has the following main structures: Figure 2 、 3 As shown, the present invention comprises a vulcanized rubber layer 1 and iron teeth 2. A metal wire 3 is provided at the bottom of the iron teeth 2. The metal wire 3 is restrained by brackets 4 on both sides and a stopper 5. The metal wire 3 allows each iron tooth 2 to form a unified structure, thereby enhancing the overall anti-digging effect. The foregoing is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications and substitutions made by those skilled in the art within the scope of the present invention are intended to be within the scope of protection of the present invention.
