Description

Technical Field

[0001] This utility model relates to the field of radiator shaping fixture technology, and in particular to a radiator core shaping fixture. Background Technology

[0002] In the manufacturing of radiators, to ensure the core component—the radiator core—has good appearance and performance, it is usually necessary to shape the heat sink fins at its edges to ensure they are neatly arranged and of consistent height. For this purpose, existing technologies commonly employ a one-piece molded fixed shaping fixture. This type of fixture is simple in structure, robust and durable, and can reliably complete basic shaping tasks at a low cost on mass production lines for single-specification products. Its application value and contribution in the industry are undeniable. However, with the increasing market demand for product diversification and the rising requirements for processing precision, this fixed design is gradually showing room for optimization. Firstly, because the height of its shaping teeth is fixed, one fixture can only correspond to one specific product specification. When producing radiator cores of different thicknesses or models, multiple fixtures must be changed or stocked, which undoubtedly increases the production and management costs for enterprises, and its versatility needs to be improved. Secondly, the shaping effect of this type of tooling largely depends on the operator's experience and feel, lacking a quantifiable and precise adjustment mechanism. It is difficult to cope with the subtle height differences of products caused by tolerances or special processes, which to some extent limits its application potential in the field of high-end or customized products.

[0003] Therefore, this application provides a heat sink core shaping fixture to meet the requirements. Utility Model Content

[0004] The purpose of this application is to provide a heat sink core shaping fixture, which aims to solve the problems of poor applicability and inability to make precise adjustments in existing fixed shaping fixtures.

[0005] To achieve the above objectives, this application provides the following technical solution: a heat sink core shaping fixture, comprising, Tooling housing; A set of shaping tooth plate assembly that can be moved up and down inside the tooling housing, having multiple shaping teeth on it; A lifting and adjusting mechanism located inside the tooling housing for driving the shaping tooth plate assembly to move linearly; The lifting and adjusting mechanism includes: The worm and the worm wheel that meshes with the worm; A set of lifting screws connected to the shaping tooth plate assembly; the rotation of the worm gear is converted into the linear lifting motion of the lifting screws via the worm wheel. A set of anti-rotation guide mechanisms connected to the lifting screw is used to prevent the lifting screw from rotating during the lifting process, which solves the problem of poor applicability of traditional fixed tooling.

[0006] Preferably, the lifting adjustment mechanism further includes a set of lifting nut seats that are threadedly engaged with the lifting screw; and the anti-rotation guide mechanism includes a set of anti-rotation telescopic rods, one end of which is connected to the lifting nut seats and the other end is connected to the tooling housing. The reliable anti-rotation effect is achieved through the linkage constraint, ensuring the pure linear motion of the lifting process and further improving the stability and accuracy of the adjustment.

[0007] Preferably, the lifting nut seat is connected to the bottom of the shaping tooth plate assembly via a top rod to transmit lifting thrust. The thrust is transmitted through a dual-point support, which effectively avoids the tilting of the shaping tooth plate assembly that may be caused by single-point force and ensures the uniform distribution of shaping pressure.

[0008] Preferably, the tooling housing also includes a top cover plate and a base. The lifting screw is installed on the inner bottom surface of the base. The main body of the base is U-shaped. The worm gear is installed on the side wall of the base. The cover plate is installed on the top of the base and has multiple guide slots for the shaping teeth to pass through. The two sets of opposite side wall plates of the base are provided with guide grooves on their inner walls, which not only provide a precise installation reference for each component, but also enhance the durability and operational stability of the entire tooling.

[0009] Preferably, the shaping tooth plate assembly includes a connecting base plate and a shaping tooth plate fixed on the connecting base plate. Guide bosses that slide and engage with the guide grooves of the side wall plate are provided on both sides of the connecting base plate, ensuring that the shaping tooth plate assembly can still move smoothly and without shaking when subjected to force, which is the basis for obtaining high-quality and highly consistent shaping effect.

[0010] Preferably, the lifting and adjusting mechanism also includes a drive handle connected to the worm gear for inputting rotational motion from the outside. By setting the drive handle, precise fine-tuning operations become intuitive and effortless, greatly improving the convenience and work efficiency of the tool in actual use.

[0011] In summary, the technical effects and advantages of this utility model are as follows: In this invention, a lifting and adjusting mechanism driven by a worm gear allows for continuous height adjustment over a wide range. This enables the same tooling to flexibly adapt to various radiator core products of different specifications and thicknesses, significantly reducing the number of tooling replacements or reserves required due to product changes, thereby lowering the company's overall production costs.

[0012] This invention employs a worm gear transmission mechanism. This mechanism, with its high reduction ratio, allows operators to make very fine and effortless height adjustments via a drive handle to accommodate minute product tolerances. More importantly, its inherent mechanical self-locking characteristic ensures that the shaping tooth plate assembly is reliably locked after adjustment to any height, preventing any displacement even under the impact of shaping operations. This fundamentally guarantees the high consistency and reliability of the shaping effect for each batch of products, improving the overall product quality. Attached Figure Description

Detailed Implementation

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example

[0017] refer to Figure 1-5The radiator core shaping fixture shown is designed to provide a tool applicable to radiators of different specifications and ensuring the stability and consistency of the shaping operation. The overall structure of this fixture mainly consists of a robust fixture housing 1 and a set of shaping toothed plate assemblies 2 that can be smoothly raised and lowered inside. The fixture housing 1 is designed as an integrated unit, mainly consisting of a base 5 as a supporting body and a top cover plate 3 installed on top of it. To ensure that the shaping toothed plate assembly 2 does not shake or tilt when subjected to shaping pressure, guide grooves 41 are specially provided on the inner walls of the two sets of oppositely arranged side wall plates 4 of the base 5, which precisely cooperate with the guide bosses 14 on both sides of the shaping toothed plate assembly 2. This structure forms a stable linear guide rail, which greatly improves the stability during operation and the flatness of the radiator fins after shaping. At the same time, the guide grooves 31 on the top cover plate 3 not only provide an extension channel for the shaping teeth, but also act as a barrier to effectively prevent external metal chips or dust from entering the internal precision adjustment mechanism, thereby improving the durability and reliability of the tool.

[0018] As one implementation method in this embodiment, in order to ensure the long-term stability of the adjustment accuracy of the equipment, a lifting adjustment mechanism is provided, which is a worm gear transmission mechanism mounted on the base 5. The worm 8 is horizontally installed on one side wall of the base 5. The operator can drive the worm 8 to rotate by rotating the external drive handle 7 connected to it. The worm gear 9 driven by the worm 8 is fixedly connected to the lower part of a lifting screw 10, thereby converting the rotation of the worm 8 into the rotation of the lifting screw 10. Thanks to the inherent high reduction ratio of the worm gear mechanism, the operator only needs to apply a small force to drive the lifting screw 10 to generate a huge rotational torque.

[0019] As one implementation method in this embodiment, in order to accurately transmit the pure lifting motion of the lifting screw 10 to the shaping tooth plate assembly 2, the bottom of the lifting screw 10 is rotatably mounted on the inner bottom surface of the base 5 to ensure its vertical stability during rotation. A lifting nut seat 13 is threadedly engaged with the lifting screw 10 through its internal thread. When the lifting screw 10 rotates, the lifting nut seat 13 will move up and down along it. In order to completely eliminate the tendency of the lifting nut seat 13 to rotate with the lifting screw 10, a set of anti-rotation telescopic rods 11 is creatively set up. One end of the rod is hinged to the lifting nut seat 13, and the other end is hinged to the base 5. This mechanism allows the lifting nut seat 13 to move vertically while completely restricting its rotation in any direction. Finally, the lifting nut seat 13 transmits the lifting force evenly to the connecting base plate 15 at the bottom of the shaping tooth plate assembly 2 through the two top rods 12 above it, realizing stable and reliable lifting.

[0020] The working principle of this utility model is as follows: When the height of the shaping teeth needs to be adjusted, the operator rotates the drive handle 7, which drives the worm gear 8 mounted on the side wall of the base 5 to rotate. Since the worm gear 8 meshes with the worm wheel 9, the rotation of the worm gear 8 will drive the worm wheel 9 and the lifting screw 10 fixed to it to rotate together with a large reduction ratio. Since the lifting nut seat 13 is restricted from rotation by the anti-rotation telescopic rod 11, the rotation of the lifting screw 10 will force the lifting nut seat 13, which is threaded to it, to make a pure linear lifting and lowering motion along the screw. The lifting nut seat 13 then pushes the entire shaping tooth plate assembly 2 to rise or fall through the top rod 12. Finally, the shaping teeth on the shaping tooth plate 6 will extend or retract from the guide groove 31 of the top cover plate 3 to a predetermined height, thereby realizing the precision shaping operation of radiator cores of different specifications. The entire adjustment process does not require additional locking due to the self-locking characteristics of the worm gear mechanism, which is stable and reliable, and effectively solves the technical problems of poor applicability and uneven shaping effect of traditional fixed tooling.

Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
