The section bar has been widely used in our lives, for example, in the wardrobe field as a support beam, or in the ceiling field as a decorative section bar, etc., and the section bar applied to a specific field has a specific specification length. The length of the original profile manufactured by the processing machine is often as long as tens of meters or more, and in order to be applied to a specific application, the long profile needs to be cut into a fixed-length profile according to the application, and a cutting machine is needed for the fixed-length profile. Install the laser cutting head on the cutting machine and can drive the rotatory clamping device of section bar rotation, the in-process of cutting the section bar, if the afterbody of section bar keeps unsettled, swing by a wide margin can appear, influences cutting accuracy. For this purpose, a support frame is generally provided for supporting the tail of the profile. For example, a pipe receiving follow-up supporting device disclosed in patent 202023347349.2 includes a frame, a supporting table and a plurality of sets of lifting mechanisms. The rack is provided with a length direction, a plurality of groups of lifting mechanisms are arranged at intervals along the length direction of the rack, and the lifting mechanisms are arranged on the rack and connected with the supporting table. When cutting heterotypic tubular product, the laser pipe cutting machine drives heterotypic tubular product relatively the frame rotates to make heterotypic tubular product with the support plane of propping up a supporting bench changes, and elevating system can drive it is relative to prop up a supporting bench the frame lift sets up, in order to adjust in a flexible way the support height of propping up a supporting bench, so that the surface of propping up a supporting bench can be in real time with the tubular product butt, avoids heterotypic tubular product unsettled state to appear, in order to ensure the real-time support effect can be realized to heterotypic tubular product to the supporting bench, thereby promotes the tubular product connects the support reliability of follow-up strutting arrangement to tubular product. The pipe receiving follow-up supporting device further comprises an inclined discharging mechanism, wherein the inclined discharging mechanism is used for driving the supporting table to incline towards one side of the receiving groove, so that the processed pipe automatically falls into the receiving groove. Although the pipe receiving follow-up supporting device can support materials and can obliquely discharge materials, the supporting table is in a straight plate shape, so that the effect of limiting the swing amplitude of the section is very limited, and even the section can easily escape from the supporting table in the swing process.

Disclosure of Invention

In order to solve the technical problem, the invention provides a discharging frame for cutting a section bar, which extends along the axial direction; the device is characterized by comprising a base arm and a movable auxiliary arm, wherein the auxiliary arm has at least two configuration states when viewed from the axial direction, the first configuration state is that the auxiliary arm is moved to be combined with the base arm to form an accommodating cavity, and the wall surface of an inner cavity of the accommodating cavity surrounds a cut profile so as to prevent the cut profile from escaping from the accommodating cavity along the radial direction; in a second configuration state, the auxiliary arm is moved to open the accommodating cavity, and the cut section bar accommodated in the accommodating cavity slides downwards along the wall surface of the inner cavity of the accommodating cavity in an inclined manner.

Wherein the length of the cut profile is axially extended when the elongated cut profile is placed on the tap frame.

The auxiliary arm may have only the first configuration state and the second configuration state, or may have not only the first configuration state and the second configuration state, but also two or more configuration states, such as a third configuration state, a fourth configuration state, and the like, in one application.

In the first configuration, the auxiliary arm and the base arm may be spaced apart from each other with or without an overlapping region when viewed in a radial direction (i.e., when viewed in a direction perpendicular to the axial direction).

The inner cavity wall surface of the containing cavity surrounds the cut profile, and the inner cavity wall of the containing cavity can be in a closed shape or an open shape when viewed from the axial direction, but the width of the opening is smaller than the outer diameter of the cut profile, so that in the first configuration state, the cut profile is limited in the containing cavity, cannot easily escape from the containing cavity along the radial direction, and the radial jumping amplitude of the cut profile can be limited, which is beneficial to improving the cutting precision of the cut profile.

In order to switch the auxiliary arm between the first configuration state and the second configuration state, an operator may manually drive the auxiliary arm to move, or an automatic driving device such as an air cylinder or a servo motor may drive the auxiliary arm to move. In the second configuration state, the inner cavity wall surface of the accommodating cavity provides inclined sliding guide for the cut section bar, and the cut section bar can be guided to move towards the material receiving area instead of directly falling vertically.

According to the technical scheme, compared with the prior art, the invention has the beneficial technical effects that: due to the fact that the basic arm and the auxiliary arm have the two different configuration states, the discharging frame is very simple in structure, the cut section bars are prevented from escaping from the containing cavity along the radial direction, the radial jumping amplitude of the cut section bars is limited, and the cut section bars can be guided to slide downwards in an inclined mode.

In order to achieve the above technical effects, the present invention further proposes the following embodiments:

the first embodiment: when viewed from the axial direction, the inner side of the base arm is provided with a first wall surface extending in an inclined downward direction, and in a first configuration state, the auxiliary arm and the base arm are moved to be combined, so that the cut profile is blocked at the inner side of the first wall surface; in a second configuration, the auxiliary arm is moved away from the base arm, the containing cavity is opened and the cut profile slides along the first wall surface.

The first wall surface belongs to the inner side wall surface of the base arm and also belongs to a part of the inner cavity wall surface of the accommodating cavity. The first wall surface, whether in the first configuration or in the second configuration, always extends in an obliquely downward direction, and is able to guide the cut profile to slide obliquely downward in the second configuration. In the first configuration, the cut profile is blocked inside the first wall, but it is not excluded that the cut profile is blocked inside the auxiliary arm at the same time. In the second configuration, the profile to be cut slides obliquely downwards under the guidance of the first wall surface by means of its own weight. The first wall surface becomes a first-order inclined guide surface.

The second embodiment: seen from the axial direction, the inner side of the auxiliary arm is provided with a second wall surface, and in a first configuration state, the auxiliary arm and the base arm are moved to be combined, so that the cut profile is blocked on the inner side of the second wall surface; in a second configuration, the auxiliary arm is moved to open the accommodating cavity, so that the second wall surface is arranged to extend in an inclined downward direction, and the cut profile slides along the second wall surface.

The second wall surface belongs to the inner side wall surface of the auxiliary arm and also belongs to a part of the inner cavity wall surface of the accommodating cavity. In a first configuration, it is not excluded that the cut profile is blocked inside the second wall, but at the same time inside the base arm. In the process of switching from the first arrangement state to the second arrangement state, the posture of the second wall surface is changed from non-inclined downward extension to inclined downward extension. In the second arrangement, the cut profile slides obliquely downwards under its own weight guided by the second wall surface, which is the first-order inclined guide surface.

Third embodiment: the inner side of the auxiliary arm is provided with a second wall surface extending in an inclined downward direction when viewed from the axial direction, and in a first configuration state, the auxiliary arm and the base arm are moved to be combined, so that the cut profile is blocked at the inner side of the second wall surface; in a second configuration, the auxiliary arm is moved to open the containing cavity and let the cut profile slide along the second wall surface.

The second wall surface belongs to the inner side wall surface of the auxiliary arm and also belongs to a part of the inner cavity wall surface of the accommodating cavity. The second wall surface always extends in an obliquely downward direction regardless of the first arrangement state or the second arrangement state. In a first configuration, it is not excluded that the cut profile is blocked inside the second wall, but at the same time inside the base arm. In the second arrangement, the cut profile slides obliquely downward by its own weight under the guiding action of the second wall surface, which becomes a first-order inclined guide surface.

Fourth embodiment: when viewed from the axial direction, the inner side of the basic arm is provided with a first wall surface extending in an inclined downward direction, the inner side of the auxiliary arm is provided with a second wall surface, and in a first configuration state, the auxiliary arm and the basic arm are moved to be combined, so that the cut profile is blocked at the inner sides of the first wall surface and the second wall surface; in a second configuration state, the auxiliary arm is moved to open the accommodating cavity, the second wall face is arranged to extend in an inclined downward direction and approach the first wall face, and the cut section bars sequentially slide along the first wall face and the second wall face.

The first wall surface belongs to the inner side wall surface of the base arm and also belongs to a part of the inner cavity wall surface of the accommodating cavity. The first wall surface always maintains a posture extending in an obliquely downward direction regardless of the first arrangement state or the second arrangement state.

The second wall surface belongs to the inner side wall surface of the auxiliary arm and also belongs to a part of the inner cavity wall surface of the accommodating cavity. In the process of switching from the first arrangement state to the second arrangement state, the posture of the second wall surface is changed from extending in a non-inclined downward direction to extending in an inclined downward direction, and the extending direction may be the same as or different from that of the first wall surface. In the second configuration, the second wall is close to the first wall in various ways in a specific application, and it is possible that the upper end of the second wall abuts against the middle of the first wall; or the upper end of the second wall surface and the lower end of the first wall surface are arranged at intervals, but the interval is smaller than the outer diameter of the cut profile, so that the cut profile is not influenced to obliquely slide onto the second wall surface from the first wall surface; still alternatively, the middle portion of the second wall surface abuts against the lower portion of the first wall surface. In this way, the first wall surface is given slide guide, and the second wall surface receives the cut material slid from the first wall surface, and the stroke of the slide guide to the cut material is extended, and the first wall surface and the second wall surface become the first-order inclined guide surfaces.

In the fourth embodiment, a further technical solution may also be that the auxiliary arm is hinged with the base arm; when viewed from the axial direction, in a first configuration state, the auxiliary arm is turned upwards to be combined with the base arm, so that the cut profile is blocked between the first wall surface and the second wall surface; in a second configuration, the auxiliary arm is turned downwards to open the accommodating cavity, so that the second wall surface is arranged to extend in an inclined downward direction in the same inclined direction as the first wall surface, and the first wall surface and the second wall surface are spliced into an inclined surface extending in an inclined downward direction.

Wherein the manner in which the auxiliary arm is articulated with the base arm is varied, as exemplified by the case in which the auxiliary arm is in the second configuration, such as with the upper end of the auxiliary arm articulated with the lower end of the base arm; or the upper end of the auxiliary arm is hinged with the middle part of the base arm; or, the middle part of the auxiliary arm is hinged with the lower end of the base arm, so that the modes are various and are not listed. In the second arrangement, the second wall surface and the first wall surface both extend obliquely downward in the same direction, for example, both extend obliquely downward in a manner of being high and low or in a manner of being low and high, and the stroke of the slide guide of the cut profile in the same direction is extended.

In the fourth embodiment, a further aspect may be that the base arm further includes a third wall surface inside the base arm as viewed from the axial direction, the first wall surface, the second wall surface, and the third wall surface are each a flat surface, and a width of the first wall surface corresponds to a width of the second wall surface; in the first arrangement state, the accommodating chamber formed by the combination of the second wall surface of the movable auxiliary arm, the first wall surface of the base arm and the third wall surface of the base arm is substantially in the shape of an isosceles triangle. Such a construction considerably simplifies the manufacturing process of the base arm and the auxiliary arm and makes it possible to predict the position of the central axis of the receiving chamber relatively easily by eye, facilitating the adjustment of the relative position of the central axis of the receiving chamber and the centre axis of the clamping device for clamping the cut profile. The third wall surface belongs to the inner side wall surface of the base arm and also belongs to a part of the inner cavity wall surface of the accommodating cavity.

In a further aspect, when viewed in a radial direction, in the first configuration state, there is an overlapping area between the auxiliary arm and the base arm, and an axial length of the accommodating cavity in the overlapping area is not less than 0.5m. In this way, the auxiliary arm and the base arm can simultaneously limit the radial runout amplitude of the section bar section in the overlapping area on the cut section bar, and the degree of radial bending deformation of the section bar section in the rotating and swinging process is reduced.

The material receiving table top is used for receiving the cut section bar released from the accommodating cavity. Thus, the receiving platform surface becomes a secondary inclined guide surface.

The technical scheme includes that the robot arm further comprises a base frame, wherein a vertically extending guide rail, a sliding seat arranged on the guide rail in a sliding manner, a lifting driver used for driving the sliding seat to move up and down and a driving assembly for the arm are arranged on the base frame, the driving assembly for the arm comprises a cylinder mounting seat and a driving cylinder used for driving the auxiliary arm to move and switch between the first configuration state and the second configuration state, a main body of the driving cylinder is rotatably arranged on the cylinder mounting seat, and a cylinder movable rod is movably connected with the auxiliary arm; and the cylinder mounting seat and the base arm are respectively and fixedly connected to the sliding seat. Wherein, the lifting driver is a servo motor or a manual driver.

In a further aspect, when viewed in the axial direction, in the first arrangement state, the inner cavity wall surface of the receiving cavity surrounds the cut profile at least within a 270 ° spatial range. The inner cavity wall surface of the accommodating cavity can surround the cut section bar within the range of 270 degrees, 290 degrees, 360 degrees and the like.

The axial end part of the auxiliary arm is provided with a first flanging which extends obliquely and outwards; and in the first configuration state, the first outward turning edge and the second outward turning edge are combined to form a material guide bell mouth which is communicated with the accommodating cavity and gradually enlarged from inside to outside. Therefore, the cut section bar can be conveniently introduced into the accommodating cavity by utilizing the guide bell mouth. Wherein, the above-mentioned "extending outwards" means extending towards the outer space of the accommodating cavity.

In addition, the invention also provides a profile cutting machine which comprises the discharge frame for cutting the profile, wherein a clamping device for clamping and driving the cut profile to rotate and a laser cutting head for cutting the cut profile are arranged at the upstream of the discharge frame.

The invention has the characteristics and advantages, so the invention can be applied to the discharge frame for cutting the section and the section cutting machine.

Detailed Description

Various implementation details disclosed below may be selectively applied or combined in one embodiment even if not directly related or synergistic in functional terms, except where expressly specified to belong to equivalent or alternative embodiments.

As shown in fig. 1 to 7, a discharging frame for cutting sectional materials, which extends along an axial direction; the auxiliary arm has at least two configuration states when viewed from the axial direction, wherein the first configuration state is that the auxiliary arm is moved to be combined with the base arm to form an accommodating cavity, and the wall surface of an inner cavity of the accommodating cavity surrounds the cut section bar so as to prevent the cut section bar from escaping from the accommodating cavity along the radial direction; in a second configuration state, the auxiliary arm is moved to open the accommodating cavity, and the cut section bar accommodated in the accommodating cavity slides downwards along the wall surface of the inner cavity of the accommodating cavity in an inclined manner. Furthermore, when viewed in the axial direction, in the first arrangement state, the inner cavity wall surface of the accommodating cavity surrounds the cut profile at least within a 270 ° spatial range. The inner cavity wall surface of the accommodating cavity can surround the cut section bar within the range of 270 degrees, 290 degrees, 360 degrees and the like.

The structure of the discharging frame 100 to which the present invention is applied will be further described with reference to the accompanying drawings.

As shown in fig. 1 to 3, a configuration of a discharge frame 100 according to a first embodiment is schematically illustrated. When viewed from the axial direction, the inner side of the base arm 1 is provided with a first wall surface 11 extending in an inclined downward direction, the inner side of the auxiliary arm 2 is provided with a second wall surface 21, and in a first configuration state, the auxiliary arm 2 and the base arm 1 are moved to be combined, so that the cut section bar is blocked at the inner sides of the first wall surface 11 and the second wall surface 21; in the second configuration, the auxiliary arm 2 is moved to open the accommodating cavity 10, the second wall 21 is then arranged to extend in an obliquely downward direction and close to the first wall 11, and the cut profile is slid down along the first wall 11 and the second wall 21 in sequence.

The first wall surface 11 belongs to an inner side wall surface of the base arm 1 and also belongs to a part of an inner cavity wall surface of the accommodating cavity 10. The first wall surface 11 is always held in a posture extending obliquely downward regardless of the first arrangement state or the second arrangement state.

The second wall surface 21 belongs to an inner wall surface of the auxiliary arm 2 and also belongs to a part of an inner cavity wall surface of the accommodating cavity 10. In the process of switching from the first arrangement state to the second arrangement state, the posture of the second wall surface 21 is changed from extending in a non-inclined downward direction to extending in an inclined downward direction, and the extending direction thereof may be the same as or different from the extending direction of the first wall surface 11, for example, one may extend in an inclined downward direction in a manner of being high and low in front and low in back, the other may extend in an inclined downward direction in a manner of being low and high in front, or both may extend in an inclined downward direction in a manner of being high and low in front. In the second configuration, the second wall 21 is close to the first wall 11 in various ways, and it is possible that the upper end of the second wall 21 abuts against the middle of the first wall 11; or, the upper end of the second wall surface 21 and the lower end of the first wall surface 11 are arranged at intervals, but the interval is smaller than the outer diameter of the cut profile, so that the cut profile is not influenced to slide onto the second wall surface 21 from the first wall surface 11 in an inclined manner; alternatively, the middle portion of the second wall surface 21 abuts against the lower portion of the first wall surface 11. In this way, the second wall surface 21 can receive the cut material slid from the first wall surface 11, and the first wall surface 11 and the second wall surface 21 serve as first-order inclined guide surfaces by increasing the stroke of the slide guide of the cut material in addition to the slide guide given to the first wall surface 11. In order to further receive the cut profile, the solution shown in fig. 7 may also be adopted, and the discharging frame 100 further includes a receiving table 3 extending in an inclined downward direction, and the receiving table 3 is used for receiving the cut profile released from the accommodating cavity 10. Thus, the receiving table surface 3 becomes a secondary inclined guide surface.

Further, the auxiliary arm 2 is hinged with the base arm 1; in a first configuration, seen in the axial direction, the auxiliary arm 2 is turned upwards to combine with the base arm 1, so that the cut profile is trapped between the first wall 11 and the second wall 21; in the second configuration, the auxiliary arm 2 is turned downwards to open the accommodating cavity 10, and the second wall surface 21 is arranged to extend in an inclined downward direction in the same inclined direction as the first wall surface 11, and the first wall surface 11 and the second wall surface 21 are connected to form an inclined surface extending in an inclined downward direction. The manner of hinging the auxiliary arm 2 with the base arm 1 is various, and in the present embodiment, in the second configuration state, the upper end of the auxiliary arm 2 is hinged with the lower end of the base arm 1 (in other embodiments, the upper end of the auxiliary arm 2 is hinged with the middle of the base arm 1; or the middle of the auxiliary arm 2 is hinged with the lower end of the base arm 1). In the second arrangement, the second wall surface 21 and the first wall surface 11 both extend obliquely downward in the same direction, and the stroke of sliding guide in the same direction to the cut profile is extended.

Further, the base arm 1 further has a third wall surface 12 on the inner side thereof as viewed in the axial direction, the first wall surface 11, the second wall surface 21, and the third wall surface 12 are flat surfaces, and the width of the first wall surface 11 corresponds to the width of the second wall surface 21; in the first arrangement state, the housing chamber 10 formed by the combination of the second wall surface 21 of the auxiliary arm 2, the first wall surface 11 of the base arm 1, and the third wall surface 12 thereof is substantially in the shape of an isosceles triangle. Such a configuration greatly simplifies the manufacturing process of the base arm 1 and the auxiliary arm 2, and allows the position of the central axis of the housing chamber 10 to be relatively easily predicted by the naked eye, facilitating the adjustment of the relative position of the central axis of the housing chamber 10 to the centre axis of the clamping device for clamping the profile to be cut.

Further, in the first configuration, the auxiliary arm 2 and the base arm 1 have an overlapping area when viewed in the radial direction, and the axial length of the accommodating cavity 10 in the overlapping area is not less than 0.5m. In this way, the auxiliary arm 2 and the base arm 1 can simultaneously limit the radial runout amplitude of the section bar segment in the overlap area on the cut section bar, and reduce the degree of radial bending deformation of the section bar segment in the process of rotary swing.

Further, a first flanging 13 extending obliquely outwards is arranged at the axial end part of the base arm 1, and a second flanging 23 extending obliquely outwards is arranged at the axial end part of the auxiliary arm 2; in the first configuration state, the first outward turning edge 13 and the second outward turning edge 23 are combined to form a material guiding bell mouth 101 which is communicated with the accommodating cavity 10 and gradually expands from inside to outside. In this way, the guiding bellmouth 101 can be used to easily introduce the cut profile into the receiving cavity 10.

The discharging frame 100 further comprises an underframe 4, a guide rail 5 extending vertically, a sliding seat 51 slidably disposed on the guide rail 5, a lifting driver for driving the sliding seat 51 to move up and down, and an arm driving assembly 7 are disposed on the underframe 4, the arm driving assembly 7 includes a cylinder mounting seat 70 and a driving cylinder 71 for driving the auxiliary arm 2 to move and switch between the first configuration state and the second configuration state, a main body of the driving cylinder 71 is rotatably disposed on the cylinder mounting seat 70, and a cylinder movable rod 710 of the driving cylinder 71 is hinged to the auxiliary arm 2; the cylinder mounting seat 70 and the base arm 1 are respectively fixedly connected to the sliding seat 51. Wherein the lifting driver is a manual driver 6 (which may be a servo motor in other embodiments). The manual driver 6 includes a driving screw 61, a driving nut (not shown) screwed to the driving screw 61, and a handle 62 for driving the driving screw 61 to rotate, and the sliding base 51 is connected to a lower end of the driving screw 61. When the driving screw 61 is rotated, the driving screw 61 carries the slider 51 up and down. Further alternatively, the slide base 51 is connected to the drive nut, and the slide base 51 can be moved up and down by the drive nut when the drive screw 61 is rotated.

As shown in fig. 8, the present invention further provides a profile cutting machine, which includes the discharging rack 100 for cutting the profile, and a clamping device (not shown in the figure) for clamping and driving the cut profile to rotate and a laser cutting head 200 for cutting the cut profile are disposed at the upstream of the discharging rack 100. One end of the cut profile is clamped on the clamping device and arranged below the laser cutting head 200, and the other end is enclosed in the accommodating cavity 10.
