In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention, however, the present invention may be practiced otherwise than as described herein, and therefore the present invention is not limited to the specific embodiments of the disclosure that follow.
In the embodiment 1, as shown in fig. 1 to 5, the present embodiment aims to provide a device capable of realizing mechanical shaping of a rim to solve the technical problems of low efficiency and easy damage of the existing manual shaping, and therefore, the rim shaping device for producing an automobile rim provided by the present embodiment comprises a frame 1 and a shaping component arranged on the frame 1, in the present embodiment, the whole shape of the frame 1 is in a toppling L-shaped configuration, and the shaping component is arranged at the position of the long side of the frame 1, so that the purpose of the configuration is mainly considered that a large number of hydraulic devices are applied in the shaping component, and a hydraulic pump station is conveniently arranged, so that the shape of the shaping component is in the toppling L-shaped configuration.
The plastic subassembly that this embodiment provided includes the plastic motor 2 that the power end set up and sets up at the fixing base 21 of plastic motor 2 power end, is provided with plastic hydro-cylinder 22 on the fixing base 21 level, like this, under the effect of plastic motor 2, plastic hydro-cylinder 22 can rotate, is connected with plastic piece 23 at the power end of plastic hydro-cylinder 22, like this, if will need the wheel hub suit of plastic outside plastic piece 23, because the rotation of plastic motor 2 and the slow extension of plastic hydro-cylinder 22, can warp wheel hub's shape gradually, until the finished product. In this embodiment, both ends of the hydraulic cylinder are extended from the fixing base 21, so that the purpose of this is to give the shaping block 23 a longer expansion and contraction amount, so as to ensure different inferior products. The number of degrees of the central angle of the shaping block 23 is preferably 5 to 10 degrees. This thickness ensures the quality of the shaping block 23 without being too great, which would affect the shaping effect.
For this reason, in order to better clamp the hub, in this embodiment, the shaping assembly further includes a clamping mechanism wrapped outside the fixing base 21, and the main purpose of the clamping mechanism is to fix the hub to be shaped. Considering the difficulty of shaping, in order to ensure the success rate of shaping, in this embodiment, a segment shaping method is used to shape the spoke, specifically, the spoke is divided into an upper segment and a lower segment, and half of the spoke is shaped. For this purpose, the clamping mechanism provided in this embodiment includes an upper clamping unit 3 and a lower clamping unit 4 that are disposed up and down, where the lower clamping unit 4 includes a fixed barrel 41 that is wrapped outside the shaping motor 2, and in this embodiment, the section of the fixed barrel is disposed in a convex shape, where the lower half of the fixed barrel has two purposes, one purpose is to form a base on which a hub is placed, and the other purpose is to protect the shaping motor 2. For this reason, the opening of the fixed barrel 41 is arranged downward, the power end of the shaping motor 2 is arranged through the top of the fixed barrel 41, an inner wall clamping block 42 is arranged on the side wall of the fixed barrel 41, the inner wall clamping block 42 is arranged on the upper half part of the fixed barrel, the diameter of the middle of the existing steel wheel hub can be known to be smaller than that of two sides through knowing the existing steel wheel hub, and the structure is symmetrical, therefore, one surface of the inner wall clamping block 42 far away from the fixed barrel 41 is attached to the lower end of the inner surface of the rim, and in order not to influence the rotation shaping of the shaping block 23, the height of the inner wall clamping block 42 is not more than one third of the rim height, in this embodiment, one third of the rim height. In this way, the rotation of the shaping block 23 does not touch the inner wall clamping block 42.
Because the inner wall of the lower half of the rim is supported by the inner wall clamping blocks 42, an outer wall clamping block 43 matched with the inner wall clamping block 42 is further arranged on the frame 1, one end, away from the inner wall clamping block 42, of the outer wall clamping block 43 is provided with a clamping oil cylinder 44, the clamping oil cylinder 44 is fixed on the frame 1, the outer wall clamping block 43 is uniformly distributed on the periphery of the rim in a ring shape, in the embodiment, 4 outer wall clamping blocks 43 are arranged in total, the arc length of the outer wall clamping block 43 is larger than the arc of the inner wall clamping block 42, wherein the central angle of the inner wall clamping block 42 is 5-10 degrees, and the arc length of the outer wall clamping block 43 is 10-20 degrees.
The setting of lower clamping unit 4 has realized waiting the fixed of plastic rim, and the main purpose of last clamping unit 3 is moulding, under the drive of plastic piece 23, realize the determination to the shape, and for this reason, go up clamping unit 3 including setting up the shaping arc piece 31 at the rim periphery, shaping arc piece 31 is the annular and distributes at the periphery of rim, in this embodiment, be provided with four shaping arc pieces 31, constitute the ring form setting between four shaping arc pieces 31, will wait the wheel hub of plastic and place in it, be provided with shaping hydro-cylinder 32 in the one end that shaping arc piece 31 kept away from shaping piece 23, shaping hydro-cylinder 32 is fixed in frame 1, shaping arc piece 31 keeps away from the one side laminating of shaping hydro-cylinder 32 and the upper half of rim surface and sets up, shaping hydro-cylinder 22 is kept away from to shaping piece 23 one side and the upper half laminating of rim internal surface. Thus, along with the continuous rotation and lamination of the shaping block 23, the part to be corrected of the rim is continuously laminated on the shaping arc block 31, and finally, a qualified finished product is obtained.
In order to ensure the stability of movement of the shaping arc block 31 and the outer wall clamping block 43, in this embodiment, a sliding groove 11 for sliding the shaping arc block 31 and the outer wall clamping block 43 is provided on the frame 1, and guide bars are provided on the side walls of the shaping arc block 31 and the outer wall clamping block 43.
For convenience sakeThe shaping block 23 is shaped, and an electric heating device 311 is provided on the shaping arc block 31. Specifically, a shaping electrode is disposed in the shaping arc block 31, and the shaping electrode is exposed on one surface of the shaping arc block 31, which is close to the rim. The shaping electrode is provided with an energizing core rod which stretches into the shaping electrode, and the part of the energizing core rod exposed outside is sleeved with an insulating sleeve which is made of Al for ensuring safety 2 O 3 A sleeve made of ceramic high-temperature resistant insulating material is used for protecting the energizing core rod, and an insulating plate is arranged around the shaping electrode for protecting the shaping electrode, wherein the insulating plate also adopts Al 2 O 3 The ceramic material realizes that the shaping electrode is isolated from the shaping arc block 31. Of course, other electric heating modes can be adopted, and the electric heating assembly belongs to the existing mature technology, so that the electric heating assembly is not described more herein, and therefore, better deformation is realized under the condition of heating, and the shaping speed and efficiency are increased.
