Description

Technical Field

[0001] This utility model relates to the field of profile processing equipment technology, and in particular to a profile processing center. Background Technology

[0002] In existing profile processing, profiles (such as aluminum alloy, PVC, and thermally broken aluminum profiles) are sawn to the required length for door and window frames, sashes, mullions, and other components. This results in cut surfaces at both ends, which are typically rough, possibly with burrs or unevenness, and their shape is the original cross-sectional shape of the profile. In practical applications, during door and window assembly, the profiles (especially at corner joints and mullion connections) need to fit tightly or form specific connection structures (such as mortise and tenon joints, interlocking joints, and grooves for mounting brackets). Therefore, the cut profiles need to undergo end milling. End milling involves milling specific contours, grooves, steps, bevels, holes, etc., onto the end faces of the profiles according to design requirements.

[0003] In existing profile processing, the cutting and milling processes need to be carried out by two separate machines, which takes up a lot of time in the profile transfer process, resulting in low processing efficiency. Utility Model Content

[0022] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention 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 invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0023] The terms "first," "second," etc., in the specification, claims, and accompanying drawings of this utility model are used to distinguish different objects, not to describe a specific order. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion. For example, a process, method, apparatus, product, or server that includes a series of steps or units is not limited to the listed steps or units, but may optionally include steps or units not listed, or may optionally include other steps or units inherent to these processes, methods, products, or servers.

[0024] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of the present invention. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0025] This utility model discloses a specific implementation of a profile processing center. Please see [link to implementation details]. Figs. 1 to 4 The system includes a frame 1, which has guide rails 11 spaced apart in the longitudinal direction and arranged in the transverse direction. Each guide rail 11 has a first milling slide 21 and a second milling slide 31 that can slide along the guide rails 11. A first end-face milling mechanism 2 is mounted on the first milling slide 21, and a second end-face milling mechanism 3 is mounted on the second milling slide 31. The first end-face milling mechanism 2 includes at least two rotatable first milling cutters 201, and the second end-face milling mechanism 3 includes at least two rotatable second milling cutters 301. The two first milling cutters 201 and the two second milling cutters 301 have different tooth sizes.

[0026] The machining center in this embodiment is equipped with two independent end-face milling mechanisms (first end-face milling mechanism 2 and second end-face milling mechanism 3), each mounted on an independently sliding milling slide. This allows end-face milling at both ends of the profile to be performed simultaneously (if space and process permit), or rapidly and continuously (the milling slide moves to both ends of the profile). Compared to single-end milling equipment or equipment that requires moving the profile to mill the other end, efficiency is increased several times over. Furthermore, each end-face milling mechanism includes at least two milling cutters with different tooth sizes (e.g., a roughing cutter for quickly removing most of the allowance, and a finishing cutter for obtaining precise dimensions and a smooth surface). This design allows the entire process from roughing to finishing of the end face to be completed in one station or one setup, without changing tools or performing multiple milling operations, further improving the efficiency of single-end milling.

[0027] As an improvement, a cutting mechanism 4 is fixedly mounted on the frame 1, located between the first end milling mechanism 2 and the second end milling mechanism 3. The cutting mechanism 4 includes a movable saw blade. In this embodiment, the machining center integrates the cutting mechanism 4 and the two end milling mechanisms onto the same device (frame 1). After the profile is cut, there is no need to unload it from the cutting device, transport it, and then clamp it onto another milling device. This directly eliminates the time, manpower, and equipment downtime required for transferring the profile between the cutting and milling processes, significantly shortening the overall processing cycle and solving the problem of low production efficiency in the past. The profile only needs to be clamped and positioned once on the machining center. At the same station, the cutting and blanking and the end milling of both ends can be completed sequentially (or even partially simultaneously), achieving multiple processes completed with a single clamping. In addition, the cutting mechanism 4 is fixed between the two end milling mechanisms, and the milling slide moves laterally (usually perpendicular to the length direction of the profile) along the guide rail 11. This layout concentrates the spatial positions of each functional module (cutting, left-end milling, right-end milling) and optimizes the motion path. The equipment can smoothly execute the automated process of cutting, milling slide movement and positioning, one-end milling and the other-end milling. The processes are closely connected, the equipment utilization rate is high, the idle stroke is small, and the risk of cumulative positioning error caused by multiple clamping is avoided. It also fundamentally solves the efficiency bottleneck caused by process separation.

[0028] In this embodiment, a rack 12 is fixedly mounted on the side of the guide rail 11 and mounted on the frame 1. A translation motor 13 is fixedly mounted on both the first milling slide 21 and the second milling slide 31. The output shaft of the translation motor 13 extends towards the rack 12, and a translation gear 14 meshing with the rack 12 is fixedly connected to the end of the output shaft of the translation motor 13. During operation, the translation motor 13 starts and drives the translation gear 14 to rotate, causing the first milling slide 21 or the second milling slide 31 to slide along the guide rail 11, thereby moving to the appropriate position.

[0029] In this embodiment, a first longitudinal slide rail 22 is fixedly installed on the first milling slide plate 21, and the first longitudinal slide rail 22 is provided with a first longitudinal slide plate 23 that slides with it; a first longitudinal motor 24 is also fixedly installed on the first milling slide plate 21, and a first longitudinal lead screw 25 is fixedly connected to the output shaft of the first longitudinal motor 24.

A first vertical slide rail 26 is fixedly installed on the first longitudinal slide plate 23. The first vertical slide rail 26 is provided with a first vertical slide plate 27 that slides with it. A first rotary motor 28 is fixedly installed on the first vertical slide plate 27. A first milling motor 29 is fixedly connected to the rotating disk of the first rotary motor 28.

A first lifting screw 203 is fixedly connected to the output shaft of the first lifting motor 202. A first lifting screw nut 204 is provided with it that slides with it. The first lifting screw nut 204 is fixedly connected to the first vertical slide plate 27.

[0030] The working process of the first end milling mechanism 2 in this embodiment is as follows: First, coarse positioning: the entire first end milling mechanism 2 moves laterally (X-axis) along the guide rail 11 via the first milling slide 21, approaching the end area of ​​the profile. Second, fine positioning: the first longitudinal motor 24 drives the first longitudinal slide 23 and all its components to make longitudinal (Y-axis) fine adjustments along the first longitudinal slide rail 22 via the first longitudinal lead screw 25 and the first longitudinal lead screw nut, so that the first milling cutter 201 is precisely aligned with the specific processing position in the width direction of the profile. Third, angle setting: the first rotary motor 28 drives its rotary disk to rotate as needed, adjusting the first milling motor 29 and the first milling cutter 201 to the set processing angle. Fourth, height setting: the first lifting motor 202 drives the first vertical slide 27 and its components (including the milling cutter with the set angle) to rise and fall along the first vertical slide rail 26 via the first lifting lead screw 203 and the first lifting lead screw nut, setting the first milling cutter 201 to the correct cutting depth (Z-axis). Fifth step, milling: The first milling motor 29 starts, driving the first milling cutter 201 to rotate at high speed. Sixth step, feed motion: While the first milling cutter 201 is rotating, it usually needs to cooperate with the first milling slide plate 21 to feed along the transverse (X-axis) direction of the guide rail 11 of the frame 1 (or other auxiliary feed) so that the rotating first milling cutter 201 moves relative to the end face of the profile according to the set path to complete the milling of specific contours, grooves, etc.

[0031] In this embodiment, a second longitudinal slide rail 32 is fixedly installed on the second milling slide plate 31, and the second longitudinal slide rail 32 is provided with a second longitudinal slide plate 33 that slides with it; a second longitudinal motor 34 is also fixedly installed on the second milling slide plate 31, and a second longitudinal lead screw 35 is fixedly connected to the output shaft of the second longitudinal motor 34. The second longitudinal lead screw 35 is provided with a second longitudinal lead screw nut that slides with it, and the second longitudinal lead screw nut is fixedly connected to the second longitudinal slide plate 33. A second vertical slide rail 36 is fixedly installed on the second longitudinal slide plate 33. The second vertical slide rail 36 is provided with a second vertical slide plate 37 that slides with it. A second rotary motor 38 is fixedly installed on the second vertical slide plate 37. The rotary disk of the second rotary motor 38 is fixedly connected to a second milling motor 39. The second milling motor 39 is connected to the second milling cutter 301 for transmission. A second lifting motor 302 is fixedly installed at the top of the second vertical slide plate 37. The output shaft of the second lifting motor 302 is fixedly connected to a second lifting screw 303. The second lifting screw 303 is provided with a second lifting screw nut 304 that slides with it. The second lifting screw nut 304 is fixedly connected to the second vertical slide plate 37.

[0032] It should be noted that the working process of the first end milling mechanism 2 is similar to that of the second end milling mechanism 3.

[0033] In this embodiment, the cutting mechanism 4 includes a gantry frame 41 fixedly mounted on a frame 1. A first slide rail 42 arranged laterally is fixedly mounted on the top surface of the gantry frame 41. The first slide rail 42 has a first slide plate 43 that slides with it. The gantry frame 41 also has a lateral moving component 44 that drives the first slide plate 43 to slide along the first slide rail 42. A second slide rail 45 arranged vertically is fixedly mounted on the top surface of the first slide plate 43. The second slide rail 45 has a second slide plate 46 that slides with it. The first slide plate 43 also has a lifting moving component 47 that drives the second slide plate 46 to slide along the second slide rail 45. A third slide rail 48 arranged longitudinally is fixedly mounted on the side of the second slide plate 46. The third slide rail 48 has a third slide plate 49 that slides with it. The second slide plate 46 also has a longitudinal moving component 50 that drives the third slide plate 49 to slide along the third slide rail 48. A third rotary motor 51 is fixedly connected to the third slide plate 49. A cutting motor 52 is fixedly connected to the rotating disk of the third rotary motor 51. The output shaft of the cutting motor 52 is fixedly connected to the saw blade.

[0034] It should be noted that the lifting and moving assembly 47, the longitudinal moving assembly 50, and the lateral moving assembly 44 are all composed of components such as motors, lead screws, and lead screw nuts, and are all conventional linear transmission mechanisms.

[0035] The working process of the cutting structure in this embodiment is as follows: First, initial positioning: the lateral moving component 44 drives the first slide plate 43 to move laterally along the first slide rail 42, positioning the saw blade assembly as a whole at the target cutting position (length direction) of the profile. Second, height setting: the lifting moving component 47 drives the second slide plate 46 to move up and down along the second slide rail 45, setting the cutting height of the saw blade (matching the profile thickness or cutting depth requirements). Third, angle setting: the third rotary motor 51 drives the rotary table to rotate, adjusting the cutting motor 52 and the saw blade to the required cutting angle (e.g., 45°). Fourth, saw blade start: the cutting motor 52 starts, driving the saw blade to rotate at high speed. Fifth, cutting (Y-axis feed): the longitudinal moving component 50 drives the third slide plate 49 to move longitudinally in a straight line along the third slide rail 48 (feed motion). The rotating saw blade smoothly cuts into the profile until the entire cross-section is cut. Sixth, reset: after cutting is completed, the saw blade stops rotating, and each moving component returns to a safe position according to the program control, ready for the next cut.

[0036] Compared with existing technologies, the profile machining center of this embodiment, by highly integrating cutting and double-end milling functions into a single device and employing independently movable dual milling heads (each equipped with a roughing and finishing combination milling cutter), completely solves the inefficiency problems caused by process separation and multiple profile transfers in the prior art. Its main advantages are the high degree of process centralization and automation, significantly shortening the overall time from profile blanking to end-face finishing, greatly improving processing efficiency, and also helping to reduce manual intervention, lower handling costs, and minimize potential clamping errors.
