Description

Technical Field

[0001] The present invention relates to the technical field of seals, in particular to the technical field of a feeding method for seals. Background Art

[0002] A seal refers to a part that prevents fluid or solid particles from leaking between adjacent mating surfaces of components and prevents foreign substances such as dust or moisture from entering the interior of a machine. Existing composite seals usually include a rubber ring and a metal skeleton ring that are connected in a composite manner, one on top of the other. During their preparation, workers usually need to manually place each group of metal skeleton rings and rubber rings into the respective cavities of the mold of a vulcanization device one by one, and then jointly send them into the furnace of the vulcanization device for vulcanization and compounding. Manually placing metal skeleton rings and rubber rings into the respective cavities of the mold one by one is very time-consuming, with low efficiency and high labor costs, and urgently needs to be solved. Summary of the Invention

[0003] The purpose of the present invention is to solve the problems in the prior art, and propose a feeding method for seals, which can effectively improve the production efficiency of composite seals, thereby greatly reducing the manufacturing cost of composite seals and enhancing the market competitiveness of products.

[0004] To achieve the above purpose, the present invention proposes a feeding method for seals, which uses a feeding device for seals to perform the feeding work. The feeding device for seals includes a carrying component and a transfer component. The carrying component includes a number of vertically arranged loading columns that can be simultaneously sleeved with the metal skeleton rings of a number of composite seals. The transfer component includes a first plate body and a second plate body that are arranged parallel to each other, one above the other, and can move relatively closer or farther away. The first plate body and the second plate body are respectively provided with a number of first plate holes and second plate holes through which the loading columns can pass. When the loading columns pass through the first plate holes and the second plate holes, a first annular gap and a second annular gap that can allow the rubber rings of the composite seals to freely pass through are respectively formed between the first plate holes, the second plate holes and the loading columns. The first plate body has magnetism and can just magnetically attract the topmost metal skeleton ring when it is in contact with the second plate body and is inserted downward with the loading column. The carrying component further includes a bottom plate and a spring. A number of the loading columns are respectively vertically installed on the top surface of the bottom plate. The spring is sleeved outside the loading column and its bottom end is connected to the top surface of the bottom plate while its top end supports a number of metal skeleton rings. The loading column includes a thick column section and a thin column section that are arranged one above the other. The metal skeleton ring and the spring are respectively sleeved outside the thick column section and the thin column section.

[0005] Specifically, it includes the following steps:

[0006] a) Sleeve a stack of metal skeleton rings of composite seals outside each of the loading columns;

[0007] b) Keep the first plate body and the second plate body in a fitting state, move the transfer assembly to directly above the bearing assembly first and then gradually move it downward, so that each material-carrying column passes through the second plate hole and the first plate hole successively until the bottom surface of the second plate body contacts the metal skeleton ring at the topmost layer;

[0008] c) Put a rubber ring of a composite seal on the outside of each material-carrying column respectively, so that each rubber ring passes through the first annular gap and the second annular gap successively and drops onto the adsorbed metal skeleton ring;

[0009] d) Keep the first plate body and the second plate body in a fitting state, move the transfer assembly onto the mold of the vulcanizing device, and make each group of metal skeleton rings and rubber rings correspond to the mold cavities of the mold one by one;

[0010] e) Separate the first plate body and the second plate body vertically, and then gradually move the first plate body away from the metal skeleton ring until each group of metal skeleton rings and rubber rings drop into the respective mold cavities of the mold.

[0011] Preferably, a guiding head with an outer diameter gradually increasing from top to bottom is provided at the top end of the thick column section.

[0012] Preferably, a transition section with a gradually decreasing outer diameter is further provided between the thick column section and the thin column section.

[0013] Preferably, several guiding columns are vertically provided on the top surface of the bottom plate, and several third plate holes and fourth plate holes for the guiding columns to pass through are respectively provided on the first plate body and the second plate body.

[0014] Preferably, the top end of the guiding column is higher than the top end of the material-carrying column.

[0015] Preferably, several first handles and second handles are respectively provided on the top surfaces of the first plate body and the second plate body, and the top end of the second handle passes through the first plate body upward.

[0016] Preferably, the transfer assembly further includes a limiting structure for limiting the maximum distance when the first plate body and the second plate body move relatively away from each other.

[0017] Preferably, the limiting structure includes a limiting rod and a limiting ring. Several limiting rods are respectively vertically fixed on the top surface of the second plate body and are connected to the limiting ring after their top ends pass through the first plate body upward.

[0018] Advantages of the present invention:

[0019] The present invention preloads a stack of metal skeleton rings through a bearing assembly provided with a plurality of material-carrying columns, and cooperates with a transfer assembly consisting of a first plate body and a second plate body which are arranged parallel to each other up and down and can move relatively closer or farther away. When the first plate body and the second plate body are attached to each other and pass through the material-carrying columns, the metal skeleton ring located on the uppermost layer can be magnetically attracted, and the metal skeleton ring is used to support the rubber ring sleeved outside the material-carrying columns later. When the first plate body and the second plate body are separated from each other, the magnetic attraction between the first plate body and the second plate body and the metal skeleton ring can be gradually disconnected, so that the stacked rubber rings and metal skeleton rings in each group automatically fall into the mold cavity under the action of gravity. Finally, the production efficiency of the composite seal is increased from about 3,500 per person per hour to about 6,000 per person per hour, thereby greatly reducing the manufacturing cost of the composite seal and improving the market competitiveness of the product. By arranging a spring outside the guide post, a certain buffer is provided for the downward pressure of the transfer assembly, which can not only improve the success rate of the transfer assembly in adsorbing the metal skeleton ring, but also reduce the damage suffered by the transfer assembly when passing through the material-carrying columns and extend the service life of the device. By arranging a thick column section and a thin column section on the material-carrying column, it not only does not affect the support of the spring on the metal skeleton ring, but also can effectively prevent the spring from coming out of the material-carrying column. By arranging a limiting structure composed of a limiting rod and a limiting ring between the first plate body and the second plate body, the first plate body and the second plate body can always be kept parallel to each other, and the maximum distance between the two can be limited, ensuring the normal use of the transfer assembly.

The loading column 12 includes a thick column section 121 and a thin column section 122 that are arranged up and down. The metal skeleton ring and the spring 13 are respectively sleeved outside the thick column section 121 and the thin column section 122.

[0028] A guiding head 1211 with an outer diameter gradually increasing from top to bottom is provided at the top end of the thick column section 121.

[0029] A transition section 123 with a gradually decreasing outer diameter is further provided between the thick column section 121 and the thin column section 122.

[0030] A plurality of guiding columns 14 are further vertically provided above the top surface of the bottom plate 11.

[0031] The top end of the guiding column 14 is higher than the top end of the loading column 12.

[0032] A plurality of first handles 23 and second handles 24 are respectively provided above the top surfaces of the first plate body 21 and the second plate body 22. The top end of the second handle 24 passes upward through the first plate body 21.

[0035] Working process of the feeder for the seal:

[0036] First, a stack of metal skeleton rings of the composite seal is sleeved outside each loading column 12. Then, hold the first handle 23 and the second handle 24, keep the first plate body 21 and the second plate body 22 in a fitting state, move the transfer assembly 2 directly above the loading assembly 1, and then gradually move it downward so that each loading column 12 passes through the second plate hole of the second plate body 22 and the first plate hole of the first plate body 21 in sequence until the bottom surface of the second plate body 22 contacts the metal skeleton ring at the uppermost layer. At this time, the metal skeleton ring is attracted by the magnetic force of the first plate body 21 and adsorbed on the bottom surface of the second plate body 22. Subsequently, a rubber ring of the composite seal is sleeved outside each loading column 12. These rubber rings will pass through the first annular gap and the second annular gap between the first plate body 21 and the second plate body 22 and the respective loading columns 12 in sequence and fall on the adsorbed metal skeleton rings. Next, continue to hold the first handle 23 and the second handle 24, keep the first plate body 21 and the second plate body 22 in a fitting state, move the transfer assembly 2 above the mold of the vulcanizing device, and make each group of metal skeleton rings and rubber rings correspond to the mold cavities of the mold one by one. Then, separate the first plate body 21 and the second plate body 22 up and down through the first handle 23 and the second handle 24, make the first plate body 21 gradually move away from the metal skeleton ring, reduce the magnetic attraction force therebetween until the magnetic attraction force is less than the gravity, so that each group of metal skeleton rings and rubber rings respectively fall into the respective mold cavities of the mold. Finally, send the mold filled with the metal skeleton rings and rubber rings into the furnace of the vulcanizing device for vulcanization.

[0037] In the present invention, a loading component with several loading columns is provided to pre-load a stack of metal skeleton rings. In cooperation with a transfer component composed of a first plate body and a second plate body which are arranged parallel to each other up and down and can move relatively closer or farther away, when the first plate body and the second plate body are attached to each other and pass through the loading columns, the metal skeleton ring at the topmost layer can be magnetically attracted, and the metal skeleton ring is used to support the rubber ring sleeved outside the loading columns later. Also, when the first plate body and the second plate body are separated from each other, the magnetic attraction with the metal skeleton ring can be gradually disconnected, so that each stack of rubber rings and metal skeleton rings stacked up and down will automatically fall into the mold cavity under the action of gravity. Finally, the production efficiency of the composite seal is increased from about 3,500 per person per hour to about 6,000 per person per hour, thereby greatly reducing the manufacturing cost of the composite seal and improving the market competitiveness of the product; by arranging a spring outside the guiding column, a certain buffer is provided for the downward pressure of the transfer component, which can not only improve the success rate of the transfer component in adsorbing the metal skeleton ring, but also reduce the damage suffered by the transfer component when inserting through the loading columns, and extend the service life of the device; by arranging a thick column section and a thin column section on the loading column, it not only does not affect the support of the spring for the metal skeleton ring, but also can effectively prevent the spring from coming out of the loading column; by arranging a limiting structure composed of a limiting rod and a limiting ring between the first plate body and the second plate body, the first plate body and the second plate body can always be kept in a parallel state, and the maximum distance between the two can be limited, ensuring the normal use of the transfer component.
