Description

Technical Field

[0001] The utility model relates to a tool for vulcanization shaping, in particular to a tool for vulcanization pre-shaping of a tapered sleeve of a vehicle. Background Art

[0002] The automobile sleeve products are the simplest to be formed by vulcanization in a straight tube type. With the popularity of new energy vehicles, the tapered sleeve products of passenger cars are more and more widely used. The vulcanization process of the tapered sleeve is different from that of the traditional straight sleeve. The tapered sleeve needs to be pre-shaped in advance before it can be loaded into the capsule for vulcanization. There is no relevant solution in the traditional process, so a pre-shaped tooling is needed. Utility Model Content

[0003] In view of the above background, the utility model provides a vulcanization pre-forming tool for a tapered sleeve of a vehicle, which prepares for the vulcanization process of the tapered sleeve.

[0004] The technical solution of the utility model is: a vehicle tapered sleeve vulcanization pre-forming tooling, comprising a lower fixing frame and an upper fixing frame;

[0005] The central axis is fixedly mounted on the lower fixing frame, and the other end of the central axis is fixedly mounted on the upper fixing frame;

[0006] A lower cone is movably sleeved on the central axis, and the lower cone is driven and supported by a cylinder;

[0007] An upper cylindrical block body is composed of 4 to 8 blocks, one end of each block is hinged on the upper fixed frame, and the other end is slidably arranged in a guide groove provided on the surface of the lower cone.

[0008] Furthermore, each block of the upper cylindrical block is a cylinder when closed, and a cone when opened.

[0009] Furthermore, each block of the upper cylindrical block body is hinged to the upper fixing frame via a ball head / pin shaft; the upper fixing frame is an equilateral polygon with the same number of sides as the blocks of the upper cylindrical block body.

[0010] Furthermore, the protruding end of the cylinder rod of the air cylinder is connected to a support plate, and two symmetrical push rods are installed on the support plate, and the two push rods are symmetrically installed on the bottom surface of the lower cone.

[0011] Furthermore, the guide grooves are arranged along the generatrix of the lower cone, and the number of the guide grooves is consistent with the number of the blocks of the upper cylindrical block body.

[0012] The technical advantages and positive effects of the utility model are:

[0013] 1. The utility model solves the problem that the traditional process does not involve the pre-forming tooling gap during the vulcanization of the tapered sleeve.

[0014] 2. Improved production efficiency. The pre-forming tooling can pre-support the tire blank suitable for the bladder according to the taper of the vulcanization bladder. It can be loaded into the bladder and vulcanized without multiple adjustments, which greatly reduces the auxiliary time increased due to unsuitable tire blanks.

[0015] 3. Improved product quality. The biggest instability of tapered sleeves is the uneven thickness of the large and small ends. Generally, the large end is thicker. The pre-forming tooling can achieve uniform pre-support during the working process, which well ensures the uniformity of product thickness.

[0016] 4. The pre-molding tooling has a simple structure and low production cost, which greatly reduces the company's investment and cycle in new product development. BRIEF DESCRIPTION OF THE DRAWINGS

[0017] Figure 1 It is an axial section view of the tooling of the utility model. DETAILED DESCRIPTION

[0018] The utility model is described in detail below in conjunction with the accompanying drawings and embodiments. However, those skilled in the art should know that the following embodiments are not the only limitations on the technical solutions of the utility model, and any equivalent changes or modifications made within the spirit of the technical solutions of the utility model should be deemed to fall within the protection scope of the utility model.

[0019] like Figure 1 As shown, the utility model is a vehicle tapered sleeve vulcanization pre-forming tooling, which is connected by a main body central axis, including a lower fixing frame 1 and an upper fixing frame 2. A central axis 3, a cylinder 4, a lower cone 5, and an upper cylindrical block 6 are arranged between the upper and lower fixing frames.

[0020] The central axis 3 is fixedly installed on the platform of the lower fixed frame 1, and the other end of the central axis 3 is fixedly installed on the upper fixed frame 2. The lower cone 5 is movably sleeved on the central axis 3, and the bottom end of the lower cone 5 is supported by the cylinder 4, which can push the lower cone 5 to slide along the central axis 3. The upper cylindrical block body 6 is composed of 4 to 8 blocks, each of which is hinged on the upper fixed frame 2 at one end, and the other end is slidably set in the guide groove 51 opened on the surface of the lower cone 5, and each block can slide along the guide groove 51; the guide groove 51 is set along the generatrix of the lower cone, and the number of the guide grooves 51 is consistent with the number of blocks of the upper cylindrical block body 6. The blocks of the upper cylindrical block body 6 slide along the guide groove 51 opened on the surface of the lower cone 5, and when the blocks are closed, a cylinder is formed, and when the blocks are opened synchronously, a cone is formed.

[0021] When the tooling is in the initial position, the upper cylindrical block 6 is closed into a cylinder, which just matches the inner diameter of the tire blank of the tapered sleeve. After the tire blank is placed in the tooling, the lower cone 5 is pushed upward along the central axis 3 by the cylinder 4; when the lower cone 5 slides upward along the central axis 3, the blocks of the upper cylindrical block 6 slide downward relative to the guide groove on the surface of the lower cone 5, and the lower ends of the blocks of the upper cylindrical block 6 are stretched open, and the upper cylindrical block 6 evolves into a cone, and then the tire blank is stretched into a cone. The stroke of the cylinder 4 determines the opening angle of each block of the upper cylindrical block 6, thereby realizing whether the size of the tire blank head is suitable for loading into the capsule.

[0022] In the above technical solution, further, the protruding end of the cylinder rod of the cylinder 4 can be connected to a support plate 7, on which two symmetrical push rods 8 are installed. The two push rods 8 are symmetrically installed on the bottom surface of the lower cone 5, and jointly push the lower cone 5 to move along the central axis 3 to ensure the balance and stability of the lower cone.

[0023] In the above technical solution, further, each block of the upper cylindrical block body 6 is hinged to the upper fixing frame 2 through a ball head / pin shaft 9; the ball head / pin shaft 9 is installed on the upper fixing frame 2, and the ball head / pin shaft 9 well enables each block of the upper cylindrical block body 6 to rotate without interference. Further, the upper fixing frame 2 is made into an equilateral polygon with the same number of sides as the number of blocks, depending on the number of blocks of the upper cylindrical block body 6.

[0024] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still make equivalent modifications or replacements to the technical solutions described in the aforementioned embodiments. Any modifications, equivalent replacements or improvements made within the spirit and principles of the present invention shall be included in the protection scope of the present invention.
