Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention will be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
The forming die shown in fig. 1 and 2 comprises a punch 1 and a lower template 2, wherein a profiling surface is arranged on the lower template 2, an elastic part 3 is arranged at the end of the punch 1, which points to the profiling surface, and when the punch 1 punches towards the lower template 2, the elastic part 3 deforms along the profiling surface, and the material is gradually extruded and formed by gradual deformation of the elastic material, so that the problems that the material is easy to accumulate and wrinkle in the forming process are effectively solved, the elastic material is not in contact with the aluminum material and cannot generate impression, the surface quality of the formed aluminum air deflector is improved, wherein the profiling surface has different depths, and after the elastic part 3 contacts the material, the punch 1 drives the elastic part 3 to continuously approach the profiling surface, and at the moment, the elastic part 3 gradually deforms along with the extrusion of the punch 1, the material is gradually deformed along with the depth of the profiling surface, so that the problems of material accumulation and wrinkling caused by hard extrusion of the steel die on the material in the prior art are solved, the contact between the elastic piece 3 and the material is in flexible contact, the problem that the rigid die can cause imprinting on the surface of a product is avoided, the subsequent processing steps for imprinting are saved, and the production efficiency is improved.
The end face of the elastic part 3 facing the profiling surface is a plane, when the punch 1 gradually approaches the lower die plate 2, the elastic part 3 deforms from the plane to the profiling surface, that is, the elastic part 3 is of a cuboid structure, and one side face of the cuboid structure is parallel to the surface of the lower die plate 2, when the elastic body approaches the profiling surface, the material moves downwards along with the elastic body, in the moving process, the material gradually contacts with the profiling surface, the material contacting with the profiling surface is supported by the profiling surface and cannot move continuously along with the elastic body, the material at the moment finishes deformation under the action of the profiling surface, the elastic body corresponding to the material starts to deform after receiving a supporting force, meanwhile, the material not connected with the profiling surface continuously moves towards the profiling surface, and the elastic body corresponding to the material cannot deform, and along with the removal of drift 1, the material with the profile surface contact increases gradually, and the material is the shaping gradually, and the elastomer also produces deformation along with receiving to support with not receiving to produce different deformations according to the size of holding power, finally, the elastic component 3 after the deformation has constituted the die cavity with the profile surface on the lower bolster 2, is used for the shaping of material.
The lower template 2 is provided with a first plane facing the punch 1, and part of the first plane is profiled to form the profiled surface, wherein the profiled surface is formed by sinking part of the first plane, and the distance from the lowest point of the profiled surface to the first plane is the maximum depth of the profiled surface, namely the maximum depth of the profiled surface is the maximum height of a formed product.
The thickness of the elastic part 3 is larger than the distance from the lowest point of the profiling surface to the first plane, namely the thickness of the elastic part 3 is larger than the maximum depth of the profiling surface, so that the elastic part 3 still does not reach the maximum deformation state after the product is molded, and the product can be reliably molded.
The projection area of the elastic part 3 on the first plane is larger than that of the profiling surface on the first plane, so that the elastic part 3 can fully cover the profiling surface, and each position of a product can be reliably molded.
The die further comprises a material pressing plate 4, the material pressing plate 4 is arranged on one side of the punch 1, the material pressing plate 4 is tightly pressed on the material by the first plane matched with the first plane, and therefore the punch 1 can punch the material conveniently.
The material of elastic component 3 includes that the dominant force is glued, rubber or silica gel, and specific material selects according to the material of material, makes elastic component 3 under the condition that has elastic deformation, and hardness is greater than the hardness of material to can extrude the material to the profile face and accomplish the shaping.
The die is applied to the air deflector, the air deflector is made of aluminum, in order to meet the appearance requirement of an air conditioner, two ends of the air deflector made of aluminum are required to be processed into curved surfaces, and the profiling surface is subjected to profiling machining according to the curved surfaces.
The above-mentioned embodiments only express several embodiments of the present invention, and the description thereof is more specific and detailed, but not construed as limiting the scope of the present invention. It should be noted that, for a person skilled in the art, several variations and modifications can be made without departing from the inventive concept, which falls within the scope of the present invention. Therefore, the protection scope of the present patent shall be subject to the appended claims.
