Abstract
Description
Technical Field
[0001] This utility model belongs to the field of tooling technology, specifically relating to an extrusion tooling. Background Technology
[0002] In fields such as machining and parts assembly, it is often necessary to perform extrusion operations on workpieces. By applying pressure, the workpiece is deformed in a predetermined manner to achieve a tight fit or meet specific dimensional accuracy requirements. Extrusion fixtures are the core equipment for completing such operations, and their structural rationality directly affects the workpiece processing quality, processing efficiency, and ease of operation.
[0003] Currently, most existing extrusion fixtures use a single extrusion surface or a simple clamping structure to extrude workpieces, which has many shortcomings. On the one hand, the extrusion part of traditional fixtures is mostly an integral structure, which is difficult to adapt to the need for simultaneous extrusion processing of multiple workpieces. It can only operate on a single workpiece at a time, resulting in low processing efficiency and failing to meet the requirements of mass production. On the other hand, for workpieces that require multi-directional positioning and extrusion, existing fixtures often can only achieve extrusion in a single direction, making it difficult to ensure uniform force on different parts of the workpiece. This can easily lead to inconsistent extrusion deformation, excessive dimensional deviations, and even workpiece damage, affecting the processing qualification rate.
[0004] Meanwhile, existing extrusion tooling suffers from poor positioning accuracy and stability. During the extrusion process, the extrusion components are prone to misalignment, which not only reduces the extrusion effect but may also accelerate tooling wear and shorten its service life due to component misalignment. Furthermore, some extrusion tooling has an unreasonable drive structure design, resulting in insufficient stability during drive and difficulty in accurately controlling the extrusion stroke and force. This makes it unsuitable for workpieces of different specifications and with varying extrusion requirements, leading to poor versatility and the need for customized tooling for different workpieces, thus increasing production costs and time.
[0005] To address the aforementioned technical issues, there is an urgent need for an extrusion fixture that can simultaneously extrude multiple workpieces, ensure uniform stress on the workpieces, provide precise positioning, and has strong versatility. This would solve the shortcomings of existing technologies, such as low processing efficiency, unstable processing quality, and poor adaptability, and meet the actual needs of mass production and high-precision processing.

[0013] In one of the extrusion fixtures described above, a limiting structure is provided between the first extrusion block and the second extrusion block. The limiting structure is used to keep the first extrusion block and the second extrusion block fixed along an arrangement direction perpendicular to the clamping block.
[0014] In the aforementioned extrusion fixture, the operating space includes a first sidewall and a second sidewall that are perpendicular to each other. The first extrusion block or the second extrusion block is movably abutted against the first sidewall along one sidewall of the arrangement direction of the pressing blocks.

[0017] Each of the second extrusion blocks is located between two of the first extrusion blocks in the arrangement direction, and multiple pressing blocks are arranged on the sidewalls of the second extrusion blocks facing the two adjacent first extrusion blocks.

[0022] The aforementioned extrusion fixture also includes a plurality of guide posts connected to the drive block. The plurality of guide posts are movably inserted into the fixture body to provide guidance for the movement of the drive block.
[0023] Compared with the prior art, the present invention has the following beneficial effects:
[0024] (1) By setting multiple corresponding clamping blocks on the opposite sides of the first extrusion block and the second extrusion block, multiple independent workpiece accommodating spaces are formed, which can extrude multiple workpieces at the same time, significantly improving batch processing efficiency and adapting to batch production conditions; by driving the first extrusion block and / or the second extrusion block to move synchronously through the drive block, multiple clamping blocks act synchronously on their respective workpieces, ensuring that the force on each part of the workpiece is uniform, effectively reducing problems such as inconsistent deformation, excessive dimensional deviation or even workpiece damage caused by uneven force, thereby improving the processing qualification rate.
[0025] (2) By having one of the extrusion blocks (such as the first extrusion block) move into contact with the side wall of the operating space, and the other extrusion block (such as the second extrusion block) contact with the drive block, a "single-sided positioning and single-sided driving" structure is formed. This structure can ensure that the thrust of the drive block is accurately transmitted to the driven extrusion block in a predetermined direction, effectively preventing the extrusion block from shifting laterally during the extrusion process, thereby improving the positioning accuracy.
[0026] (3) By setting a limiting structure, the first extrusion block and the second extrusion block are effectively constrained in the degree of freedom perpendicular to the arrangement direction of the pressing blocks, ensuring that the two move synchronously only along the arrangement direction of the pressing blocks (i.e. the extrusion direction).

Detailed Implementation
[0034] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.
[0035] It should be noted that all directional indicators (such as up, down, left, right, front, back, etc.) in this utility model embodiment are only used to explain the relative positional relationship and movement of each component in a specific posture. If the specific posture changes, the directional indicator will also change accordingly.
[0036] like Figures 1 to 6 As shown, this utility model provides an extrusion fixture for extruding workpieces. The extrusion fixture includes a fixture body 100, a first extrusion block 200, a second extrusion block 300, and a drive block 400.
[0037] Specifically, the tooling body 100 constitutes the main body and support structure of the entire extrusion tooling.
[0038] In one embodiment, the tooling body 100 has a cubic structure with an internal operating space 110. The operating space 110 has an opening structure (as shown in the figure) for picking up and placing workpieces. In another embodiment, a hinged flap can also be provided on the tooling body 100 to close the operating space 110 during workpiece pressing, so as to meet the different workpiece requirements for the operating environment (such as dust prevention, sealing, etc.).
[0039] The first extrusion block 200 and the second extrusion block 300 are arranged adjacent to each other within the operating space 110. Multiple clamping blocks 310 are provided on opposite sides of both the first extrusion block 200 and the second extrusion block 300, with each clamping block 310 on the first extrusion block 200 corresponding one-to-one with the clamping block 310 on the second extrusion block 300. A workpiece receiving space is formed between each pair of opposing clamping blocks 310. This allows for the formation of multiple independent workpiece receiving spaces, enabling the simultaneous clamping and extrusion of multiple workpieces.
[0040] The drive block 400 is movably disposed within the operating space 110 and abuts against the first pressing block 200 and / or the second pressing block 300. The drive block 400 is configured to apply a driving force to the first pressing block 200 and / or the second pressing block 300, pushing them closer to each other, thereby reducing the space for each workpiece and placing the workpieces therein under pressure.
[0041] To address the problems of existing extrusion fixtures, such as difficulty in simultaneously extruding multiple workpieces, low processing efficiency, and uneven stress and poor processing quality caused by a single extrusion structure, this solution sets multiple corresponding clamping blocks 310 on opposite sides of the first extrusion block 200 and the second extrusion block 300, forming multiple independent workpiece accommodating spaces. This allows for simultaneous extrusion of multiple workpieces, significantly improving batch processing efficiency and adapting to mass production conditions. By driving the first extrusion block 200 and / or the second extrusion block 300 synchronously through the drive block 400, the multiple clamping blocks 310 act synchronously on their respective workpieces, ensuring uniform stress on all parts of the workpiece. This effectively reduces problems such as inconsistent deformation, excessive dimensional deviations, and even workpiece damage caused by uneven stress, thereby improving the processing qualification rate.
[0042] In addition, the overall structure is simple, and different specifications of workpieces can be adapted by replacing or adjusting the clamping block 310, which reduces the customization cost of special tooling and solves the problems of poor versatility and high production cost of existing tooling.
[0043] In one embodiment, the first pressing block 200 is movably pressed against one side wall of the operating space 110 along the arrangement direction of the pressing blocks 310, and the driving block 400 is movably pressed against the second pressing block 300 along the other side wall of the pressing blocks 310; or, the second pressing block 300 is movably pressed against one side wall of the operating space 110 along the arrangement direction of the pressing blocks 310, and the driving block 400 is movably pressed against the first pressing block 200 along the other side wall of the pressing blocks 310.
[0044] Reference Figure 3 In this embodiment, the left side wall of the first pressing block 200 abuts against the inner wall of the operating space 110, and a plurality of pressing blocks 310 are provided on its right side wall; the right side wall of the second pressing block 300 abuts against the driving block 400, and a plurality of pressing blocks 310 are provided on its left side wall. When the driving block 400 moves towards... Figure 2 When the left side moves as shown, it pushes the second extrusion block 300 toward the first extrusion block 200, so that the first extrusion block 200 and the second extrusion block 300 together apply extrusion force to the workpiece in the workpiece receiving space.
[0045] By having one extrusion block (such as the first extrusion block 200) movably abut against the side wall of the operating space 110, and another extrusion block (such as the second extrusion block 300) abut against the drive block 400, a "single-sided positioning, single-sided driving" structure is formed. This structure ensures that the thrust of the drive block 400 is accurately transmitted to the driven extrusion block in a predetermined direction, effectively preventing the extrusion block from shifting laterally during the extrusion process, thereby improving positioning accuracy.
[0046] Meanwhile, because an extrusion block is constrained by the sidewall, the unexpected relative sliding and misalignment friction between the extrusion components are reduced, tooling wear is reduced, service life is extended, and the technical defects of poor stability and short service life of existing tooling are solved.
[0047] Furthermore, a limiting structure is provided between the first extrusion block 200 and the second extrusion block 300. This limiting structure is used to limit the relative displacement of the two in the direction perpendicular to the arrangement of the pressing blocks 310, so that they remain in a fixed position in that direction.
[0048] By setting the above-mentioned limiting structure, the degrees of freedom of the first extrusion block 200 and the second extrusion block 300 in the direction perpendicular to the arrangement of the clamping blocks 310 are effectively constrained (i.e., Figure 3 (In the vertical direction), ensure that the two move synchronously only along the arrangement direction of the pressing block 310 (i.e., the extrusion direction).
[0049] This not only further improves the positioning accuracy and structural stability during the extrusion process, but also avoids problems such as uneven workpiece stress and dimensional deviation caused by lateral displacement of the extrusion block. At the same time, it reduces abnormal friction and misalignment wear between components, extends the service life of the tooling while ensuring processing quality, and makes up for the shortcomings of the existing tooling in the positioning structure design.
[0050] Reference Figure 1 and Figure 4 In another embodiment, the operating space 110 includes a first sidewall 111 and a second sidewall 112 that are perpendicular to each other. The first pressing block 200 or the second pressing block 300 is movably abutted against the first sidewall 111 along one sidewall of the arrangement direction of the pressing blocks 310. The first pressing block 200 and the second pressing block 300 are both movably abutted against the second sidewall 112 along one side perpendicular to the arrangement direction of the pressing blocks 310. A driving block 400 is movably arranged in the operating space 110 along the normal direction of the first sidewall 111 and the second sidewall 112. One of the driving blocks 400 is movably abutted against the second pressing block 300 or the first pressing block 200 along the other sidewall of the arrangement direction of the pressing blocks 310, and the other driving block 400 is movably abutted against the first pressing block 200 and the second pressing block 300 along the other side perpendicular to the arrangement direction of the pressing blocks 310.
[0051] By setting two mutually perpendicular drive blocks 400, in conjunction with the first sidewall 111 and the second sidewall 112 of the operating space 110, the first extrusion block 200 and the second extrusion block 300 are positioned and extruded in two perpendicular directions, forming a bidirectional positioning and bidirectional driving structure. This ensures that the first extrusion block 200 and the second extrusion block 300 do not shift during the extrusion process, and also applies multidirectional extrusion force to the workpiece, making the workpiece more uniformly stressed and more firmly positioned, greatly improving the processing accuracy. This is suitable for workpiece processing scenarios with high positioning accuracy requirements and solves the defects of existing tooling with a single extrusion direction and poor positioning effect.
[0052] Reference Figure 2 and Figure 5 In another embodiment, a plurality of first extrusion blocks 200 and a plurality of second extrusion blocks 300 are movably disposed within the operating space 110; wherein the first extrusion blocks 200 and the second extrusion blocks 300 are alternately arranged within the operating space 110, and the number of the first extrusion blocks 200 and the number of the second extrusion blocks 300 are equal.
[0053] By setting up multiple alternating and equal-numbered first extrusion blocks 200 and second extrusion blocks 300, a larger number of workpiece accommodating spaces can be formed, enabling the simultaneous extrusion of more workpieces and further improving batch processing efficiency. At the same time, the alternating arrangement structure makes the force on each extrusion block more balanced, avoiding tooling wear or workpiece processing defects caused by excessive local force, taking into account both processing efficiency and processing quality, adapting to the needs of large-scale batch production, and solving the problem of insufficient batch processing capacity of existing tooling.
[0054] Reference Figure 6 Multiple first extrusion blocks 200 and multiple second extrusion blocks 300 are movably arranged within the operating space 110. The first extrusion blocks 200 and the second extrusion blocks 300 are arranged alternately within the operating space 110. Each second extrusion block 300 is located between two first extrusion blocks 200 in the arrangement direction, and multiple pressing blocks 310 are arranged on the sidewalls of the second extrusion block 300 facing the two adjacent first extrusion blocks 200.
[0055] By setting each second extrusion block 300 between two first extrusion blocks 200, and setting clamping blocks 310 on both sides of the second extrusion block 300, a single second extrusion block 300 can cooperate with two adjacent first extrusion blocks 200 to form two sets of workpiece accommodating spaces, which greatly improves the utilization rate of the tooling structure. At the same time, multiple extrusion structures work synchronously, further increasing the number of workpieces extruded in a single operation, improving batch processing efficiency, and the symmetrical arrangement makes the force on each part more uniform, ensuring processing consistency, and solving the defects of low utilization rate and insufficient batch processing capacity of the existing tooling structure.
[0056] In another embodiment (not shown in the figure), two first pressing blocks 200 and a plurality of second pressing blocks 300 are movably disposed within the operating space 110; wherein, the two first pressing blocks 200 are located on opposite outer sides of the operating space 110, the plurality of second pressing blocks 300 are located between the two first pressing blocks 200, and each second pressing block 300 has a plurality of clamping blocks 310 arranged on its side facing the two first pressing blocks 200.
[0057] By setting two outer first extrusion blocks 200 and multiple middle second extrusion blocks 300, with clamping blocks 310 on both sides of the second extrusion blocks 300, the number of second extrusion blocks 300 can be adjusted according to the processing batch requirements, flexibly increasing or decreasing the number of workpiece accommodating spaces to adapt to batch processing needs of different scales; at the same time, the outer first extrusion blocks 200 provide a stable positioning reference, and the middle second extrusion blocks 300 simultaneously extrude multiple workpieces, taking into account both processing flexibility and processing stability, which not only improves batch processing efficiency, but also reduces the cost of tooling adapting to different batches, solving the problem of poor batch adaptability of existing tooling.
[0058] It is worth mentioning that the workpiece accommodating space has a regular geometric shape, which can be a rectangle, square, rhombus, circle, regular pentagon or other regular shape suitable for accommodating the workpiece.
[0059] In order to drive the drive block 400, in this solution, a screw 500 is threadedly connected to the tooling body 100. One end of the screw 500 passes through one side wall of the tooling body 100 and is rotatably connected to the drive block 400 to push the drive block 400 to move.
[0060] The screw 500 is threadedly connected to the tooling body 100, and the screw 500 is rotatably connected to the drive block 400. The precision of the threaded transmission enables the smooth movement of the drive block 400, which can accurately control the extrusion stroke and extrusion force, avoiding workpiece processing deviations caused by unstable drive. At the same time, the threaded transmission has a self-locking function, which can maintain a stable extrusion force during the extrusion process, prevent the drive block 400 from retracting, improve the stability of the extrusion process, and thus ensure the consistency of processing quality, solving the problems of low accuracy and poor stability of existing tooling drives.
[0061] It should be noted that the rotatable connection between the screw 500 and the drive block 400 can be achieved by setting a bearing on the screw 500 and then fixing the outer ring of the bearing to the drive block 400.
[0062] This solution also includes a number of guide posts 600 connected to the drive block 400. The guide posts 600 are movably inserted into the tooling body 100 to provide guidance for the movement of the drive block 400.
[0063] By setting guide posts 600 on the drive block 400 and movably inserting them into the tooling body 100, precise guidance is provided for the movement of the drive block 400, preventing the drive block 400 from deviating or tilting during movement, ensuring that the thrust of the drive block 400 is accurately transmitted to the extrusion block, and improving the extrusion positioning accuracy. At the same time, the guide structure can reduce the friction between the drive block 400 and the tooling body 100, reduce component wear, extend the service life of the tooling, further improve the stability of the extrusion process and the consistency of processing quality, and make up for the shortcomings of the existing drive structure in terms of guidance.
[0064] The extrusion fixture described in this solution addresses the core pain points of existing technologies, such as low processing efficiency, uneven workpiece stress, poor positioning accuracy, insufficient stability, weak versatility, and rapid tooling wear. Through the coordinated design of multiple sets of extrusion blocks and clamping blocks 310, it enables simultaneous extrusion of multiple workpieces, significantly improving batch processing efficiency.
[0065] With the help of optimized design such as single-sided positioning, bidirectional drive and limiting structure, the extrusion component is effectively prevented from shifting, the positioning accuracy and structural stability are improved, the workpiece processing deviation and tooling wear are reduced, and the tooling service life is extended. Through the workpiece accommodating space with regular geometric shape, the flexible arrangement of extrusion blocks and the precise and stable drive guide structure, the tooling adaptability range is broadened, the cost of special tooling customization is reduced, and it can adapt to the processing needs of workpieces of different specifications and batches.
[0066] The overall structure is reasonably designed, taking into account processing efficiency, processing quality and economic efficiency, effectively solving many defects of existing extrusion tooling, and meeting the actual application needs of mass production and high-precision extrusion in the field of machining.
