Description

Technical Field

[0001] This utility model relates to the field of precision electronic component manufacturing, and in particular to an external expansion and shaping mechanism. Background Technology

[0002] In industrial production, the shaping and processing of irregularly shaped products (such as T-shaped components) has always been a technical challenge. Traditional shaping mechanisms mostly use fixed positioning fixtures, but when dealing with T-shaped products, the joint area between the lateral extension and the vertical main body often has the problem of unstable positioning. Conventional groove or planar support structures cannot effectively fit the product contour, causing the product to easily shift or rotate during processing, affecting the shaping accuracy. Especially when performing double-sided extrusion operations, existing equipment mostly adopts a synchronous pressure method, with the two sides of the outward expansion mechanism acting on the product at the same time. This can easily cause product deformation or overload damage to the positioning structure due to uneven force, making it difficult to ensure the consistency of shaping quality.

[0003] Therefore, there is an urgent need for an external expansion and shaping mechanism to solve the above problems. Utility Model Content

[0004] In view of the above-mentioned defects in the prior art, this utility model provides an external expansion and shaping mechanism, which aims to solve the problems of unstable positioning of irregularly shaped products, uneven pressure application leading to deformation, and low processing efficiency in the prior art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: an outward expansion and shaping mechanism, including a machine base, a longitudinal displacement component is provided on the end face of the machine base, a transverse displacement component is mounted above the machine base, a product carrier component is configured on the output end of the longitudinal displacement component, a plurality of product positioning structures are arrayed on the product carrier component, the product positioning structures are provided with a strip-shaped support part and a U-shaped support part in sequence from front to back, a product positioning protrusion is provided at the upper middle part of the U-shaped support part, a shaping component is configured on the output end of the transverse displacement component, the shaping component includes a lifting component and an outward expansion component located at the output end of the lifting component, and two symmetrical outer tension rods are provided on both sides of the bottom end of the outward expansion component, the two symmetrical outer tension rods are sequentially slidably pressed and installed on the left and right sides of the product on the product positioning structure through the inner side.

[0006] Based on the above, the beneficial effects of an external expansion and shaping mechanism are that it solves the problems of unstable positioning of irregularly shaped products, uneven pressure application leading to deformation, and low processing efficiency in the prior art; mainly reflected in:

[0007] 1. This utility model solves the problem of unstable positioning of irregularly shaped products by the coordinated cooperation of the strip-shaped support part, the U-shaped support part and the product positioning protrusion of the product positioning structure: the strip-shaped support part fits into the vertical part of the T-shaped product, and the U-shaped support part is engaged with the horizontal part of the T-shaped product by the positioning protrusion, forming a three-point limiting structure, which effectively prevents the product from shifting or rotating during processing.

[0008] 2. This utility model solves the problem of deformation caused by uneven pressure during synchronous pressure by controlling the timing of the step-by-step sliding extrusion of the symmetrically arranged external tension rods: the external tension rods adopt a single-sided sequential extrusion method (right first then left) to avoid stress superposition from simultaneous pressure on both sides. By releasing the extrusion pressure step by step, the risk of product deformation is reduced, while ensuring uniform shaping on both sides.

[0009] 3. This utility model solves the problem of low processing efficiency by linking the longitudinal displacement component, the transverse displacement component and the product positioning structure set in an array: During the transverse displacement process, the shaping component can simultaneously squeeze the left and right sides of multiple products in the same row in steps (for example, when the right outer tension rod processes the right side of the first product, the left outer tension rod is idle; when the right outer tension rod processes the right side of the second product, the left outer tension rod processes the left side of the first product, and so on), realizing continuous synchronous processing at multiple workstations and greatly improving the efficiency of mass production.

[0010] Furthermore, the product carrier assembly also includes a drive slider, a carrier base, and a clamping cover. The drive slider is disposed on the output end of the longitudinal displacement component, the carrier base is disposed on the drive slider, and the clamping cover is hinged to a protruding hinge portion on the upper rear side of the carrier base. A plurality of product positioning structures arranged in an array are distributed on the upper surface of the carrier base, and the clamping cover is provided with a shaping opening for each U-shaped support portion of the product positioning structure.

[0011] Based on the above, the beneficial effect of the cooperation between the drive slider and the longitudinal displacement component is to achieve precise positioning and rapid movement of the product carrier component in the longitudinal direction; the beneficial effect of the array-type product positioning structure arrangement of the carrier base is to achieve synchronous positioning and batch processing of multiple products; the beneficial effect of the shaping opening is to provide working space for the extrusion operation of the external tension rod, ensuring that the processing is not interfered with by the tight pressure cover.

[0012] Furthermore, the protruding magnetic part at the upper front end of the carrier base fixes the pressure cover by magnetic attraction, so that the lower end of the pressure cover presses against the product part located on the strip support to complete the fixation.

[0013] Based on the above, the beneficial effect of the magnetic attraction of the protruding magnetic part on the pressure cap is to ensure the stable pressing of the product part on the strip support part and prevent displacement during the processing.

[0014] Furthermore, the expansion component also includes an expansion extension rod and a CCD camera disposed at the lower end of the expansion extension rod. Two symmetrical expansion rods are respectively located on both sides of the CCD camera, and the expansion extension rod is disposed at the output end of the lifting component.

[0015] Based on the above, the beneficial effect of the CCD camera is to enable real-time visual monitoring of the processing, ensuring the accuracy of the external tension rod positioning and extrusion.

[0016] Furthermore, the working surface of the external tension rod is provided with a wear-resistant ceramic coating.

[0017] Based on the above, the beneficial effect of the wear-resistant ceramic coating is to improve the wear resistance of the working surface of the tension rod.

[0018] To more clearly illustrate the above-mentioned features of this utility model and the objectives it aims to achieve, the present utility model will be further described below in conjunction with the accompanying drawings and specific embodiments. Attached Figure Description

Detailed Implementation

[0024] like Figures 1-4As shown, an outward expansion and shaping mechanism includes a machine base 1. A longitudinal displacement component 2 is provided on the end face of the machine base 1, and a transverse displacement component 3 is mounted above the machine base 1. A product carrier component 4 is disposed on the output end of the longitudinal displacement component 2. Several product positioning structures 5 are arrayed on the product carrier component 4. The product positioning structure 5 is provided with a strip-shaped support part 51 and a U-shaped support part 52 in sequence from front to back. A product positioning protrusion 521 is provided at the upper middle part of the U-shaped support part 52. A shaping component 6 is disposed on the output end of the transverse displacement component 3. The shaping component 6 includes a lifting component 61 and an outward expansion component 62 located at the output end of the lifting component 61. Outward tension rods 621 are symmetrically arranged on both sides of the bottom end of the outward expansion component 62. The two symmetrical outward tension rods 621 are sequentially slidably pressed and installed on the left and right sides of the product on the product positioning structure 5 through their inner sides.

[0025] The product carrier assembly 4 also includes a drive slider 41, a carrier base 42, and a clamping cover 43. The drive slider 41 is disposed on the output end of the longitudinal displacement assembly 2. The carrier base 42 is disposed on the drive slider 41. The clamping cover 43 is hinged to the protruding hinge portion 421 on the upper rear side of the carrier base 42. A plurality of product positioning structures 5 arranged in an array are distributed on the upper surface of the carrier base 42. The clamping cover 43 is provided with a shaping opening 431 corresponding to the U-shaped support portion 52 of each product positioning structure 5.

[0026] The protruding magnetic part 422 at the upper front end of the carrier base 42 fixes the pressure cover 43 by magnetic attraction, so that the lower end of the pressure cover 43 presses against the product part located on the strip support part 51 to complete the fixation.

[0027] The expansion component 62 also includes an expansion extension rod 622 and a CCD camera 623 disposed at the lower end of the expansion extension rod 622. Two symmetrical expansion rods 621 are respectively located on both sides of the CCD camera 623. The expansion extension rod 622 is disposed at the output end of the lifting component 61.

[0028] The working surface of the external tension rod 621 is provided with a wear-resistant ceramic coating 624.

[0029] In summary, the specific implementation of this utility model is as follows: First, the operator places the T-shaped product to be processed on the positioning structure 5 of the product carrier assembly 4, wherein the vertical part of the product is attached to the strip support part 51, and the horizontal part is precisely positioned by the product positioning protrusion 521 of the U-shaped support part 52. Then, the pressure cover 43 is pressed down by the protruding hinge part 421 and fixed by the protruding magnetic suction part 422 to ensure that the product remains stable and does not shift during the processing.

[0030] Next, the longitudinal displacement component 2 drives the product carrier component 4 to move to the processing start position, while the lateral displacement component 3 drives the shaping component 6 to be positioned at the first processing station. The lifting component 61 drives the outward expansion component 62 to descend. The CCD camera 623 first performs visual detection on the product position and feeds back the positioning data to ensure processing accuracy. At this time, the outward expansion component 62 descends, causing the right-side outward tension rod 621 to first perform reciprocating sliding extrusion shaping on the right side of the first product. After completion, it returns to the initial position.

[0031] As the lateral displacement component 3 moves, the left outer tension rod 621 descends to extrude and shape the left side of the first product, while the right outer tension rod 621 moves to the position of the second product to extrude the right side. This alternating processing method ensures uniform force on one side while realizing continuous operation of multiple stations. After the processing of a row of products is completed, the longitudinal displacement component 2 drives the product carrier component 4 to move to the next processing position and repeats the above extrusion and shaping process.

[0032] Throughout the entire processing, the wear-resistant ceramic coating 624 on the working surface of the external tension rod 621 effectively reduces friction loss and ensures the stability of the extrusion pressure. Through the coordinated operation of the longitudinal displacement component 2 and the transverse displacement component 3, as well as the real-time monitoring of the CCD camera 623, this utility model realizes continuous, efficient, and high-precision external expansion and shaping processing of array-arranged products.

[0033] The above description is only the optimal solution embodiment of this utility model and is not intended to limit this utility model. Various modifications or substitutions made by those skilled in the art to this utility model without departing from the essence and protection scope of this utility model should also be within the protection scope of this utility model.
