[0028] See also Figures 1 to 3 The present invention provides a device for shaping a rectangular frame according to an embodiment of the present invention, comprising: a base 100, wherein the base 100 has a support surface for supporting the bottom outer wall of the rectangular frame 10, a first limiting surface for contacting the left outer wall of the rectangular frame 10, and a second limiting surface for contacting the right outer wall of the rectangular frame 10; a lower pressing plate 200, arranged along the front-to-back direction and capable of extending into the interior of the rectangular frame 10, wherein the lower pressing plate 200 is connected to a first lifting driver 210 that drives it to move up and down so as to press the bottom inner wall of the rectangular frame 10; a first side pressing plate 310 and a second side pressing plate 311. The pressing plate 320 is relatively movably arranged on the lower pressing plate 200, and the first side pressing plate 310 and the second side pressing plate 320 are connected to a driving mechanism 400 that drives the two to move back to back so as to respectively abut against the left inner wall and the right inner wall of the rectangular frame 10; the top shaping plate 500 is movably arranged on the base 100 and arranged along the front-to-back direction, and the top shaping plate 500 is connected to a second lifting driver 600 that drives it to move up and down, and the top shaping plate 500 abuts against the top wall of the rectangular frame 10 to drive the top wall of the rectangular frame 10 to be shaped to a horizontal state.
[0029] During shaping, the rectangular frame 10 is selected to be placed with its deformed surface facing upward, and the bottom outer wall of the rectangular frame 10 is pressed against the supporting surface by the lower pressing plate 200. The left outer wall and the right outer wall of the rectangular frame 10 are contacted by the first limiting surface and the second limiting surface respectively, thereby limiting the bottom, left and right sides of the rectangular frame 10, and then the top wall of the rectangular frame 10 is shaped to a horizontal state by the top shaping plate 500. The shaping device has high efficiency and precision in shaping the rectangular frame 10, so that the rectangular frame 10 has good flatness, uniform thickness and dimensional accuracy.
[0030] See also Figure 1 and Figure 3In some embodiments of the utility model, the driving mechanism 400 includes a linear driver 410 whose output end reciprocates along the front-to-back direction, and the output end of the linear driver 410 is connected to a driving block 420, and the driving block 420 has two driving inclined surfaces 421 symmetrically arranged along the front-to-back direction, and the first side pressure plate 310 and the second side pressure plate 320 are respectively provided with a first mating inclined surface 311 and a second mating inclined surface 321 abutting against the corresponding driving inclined surface 421. In this embodiment, the two driving inclined surfaces 421 gradually approach from the back to the front, and the linear driver 410 is a cylinder. When the cylinder drives the driving block 420 to move forward, the first matching inclined surface 311 moves along the driving inclined surface 421 to make the first side pressure plate 310 move to the left, and the second matching inclined surface 321 moves along the driving inclined surface 421 to make the second side pressure plate 320 move to the right, that is, the first side pressure plate 310 and the second side pressure plate 320 move back to back to tighten the left and right walls of the rectangular frame 10; when the cylinder drives the driving block 420 to move backward, the first matching inclined surface 311 moves along the driving inclined surface 421, and the second matching inclined surface 321 moves along the driving inclined surface 421, and the first side pressure plate 310 and the second side pressure plate 320 approach each other to release the rectangular frame 10, and the rectangular frame 10 can be drawn out. The driving mechanism 400 realizes the synchronous movement of the first side pressure plate 310 and the second side pressure plate 320 with a simple and compact structure, which is low in cost and convenient to use.
[0031] See also Figure 1 and Figure 3 In some embodiments of the utility model, in order to prevent the first side pressure plate 310 and the second side pressure plate 320 from moving up and down and ensure that the first side pressure plate 310 and the second side pressure plate 320 can move in the direction of tightening and releasing the rectangular frame 10, the first mating inclined surface 311 is provided with a first dovetail groove 312 arranged along its extension direction, and one driving inclined surface 421 is provided with a first dovetail protrusion matching the first dovetail groove 312; the second mating inclined surface 321 is provided with a second dovetail groove 322 arranged along its extension direction, and the other driving inclined surface 421 is provided with a second dovetail protrusion matching the second dovetail groove 322; the first side pressure plate 310 and the second side pressure plate 320 are slidably arranged on the upper surface of the lower pressure plate 200.
[0032] See also Figure 1 and Figure 2In some embodiments of the utility model, the second lifting drive 600 includes a motor 610 fixed on the base 100, a lead screw 620 connected to the output shaft of the motor 610 and extending longitudinally, and a lifting plate 630 threadedly connected to the lead screw 620, and the lifting plate 630 has two top shaping plates 500 arranged in parallel and spaced apart in the vertical direction, and a gap is defined between the two top shaping plates 500 for the top wall of the rectangular frame 10 to extend into. It can be understood that when the top wall of the rectangular frame 10 is concave, the driving motor 610 rotates in the first clockwise direction to drive the top shaping plate 500 to move upward, and the top shaping plate 500 located below can lift the top wall of the rectangular frame 10 to flatten it; when the top wall of the rectangular frame 10 is convex, the driving motor 610 rotates in the second clockwise direction to drive the top shaping plate 500 to move downward, and the top shaping plate 500 located above can press down the top wall of the rectangular frame 10 to flatten it. Among them, the first clockwise direction is one of clockwise and counterclockwise, and the second clockwise direction is the other of clockwise and counterclockwise. Moreover, the motor 610 drives the lead screw 620 to rotate to drive the lifting plate 630 to move up and down with high feeding accuracy, which is conducive to accurately adjusting the deformation distance of the top wall of the rectangular frame 10.
[0033] See also Figure 1 In some embodiments of the present invention, the base 100 is provided with a plurality of guide rods 700 penetrating the lifting plate 630, and at least two guide rods 700 are penetrating the lower pressing plate 200 to guide the lifting and lowering movement of the lower pressing plate 200. It can be understood that the guide rods 700 have a lifting and lowering guiding effect on the movement of the lifting plate 630, and at the same time, the guide rods 700 are also used for the lifting and lowering guiding of the lower pressing plate 200, achieving the effect of one object serving two purposes.
[0034] See also Figure 1 and Figure 3 In some embodiments of the utility model, in order to avoid scratching the surface of the rectangular frame 10, the base 100 is provided with two oppositely arranged first soft rubber layers 910, and the inner surfaces of the two first soft rubber layers 910 respectively constitute the first limiting surface and the second limiting surface, and the top shaping plate 500 is provided with a second soft rubber layer 920 on the surface of the top wall facing the rectangular frame 10.
[0035] See also Figure 1 and Figure 2In some embodiments of the utility model, the base 100 is provided with a detection unit 800 for detecting the deformation direction of the top wall of the rectangular frame 10, the detection unit 800 is electrically connected to a control module, and the motor 610 is connected to the control module to drive the top shaping plate 500 to move upward or downward. It should be noted that after the rectangular frame 10 is limited, the detection unit 800 can detect the deformation direction and deformation amount of the top wall of the rectangular frame 10, so that the control module controls the rotation direction and number of rotations of the motor 610 to drive the top shaping plate 500 to move upward or downward, thereby flattening the top wall of the rectangular frame 10.
[0036] See also Figure 2 In some embodiments of the utility model, the detection unit 800 includes a first distance measuring sensor 810, the transmitting end and the receiving end of the first distance measuring sensor 810 are vertically downward, and the top shaping plate 500 located above is penetrated with a first through hole 510, and the first through hole 510 is aligned with the transmitting end and the receiving end of the first distance measuring sensor 810. It should be noted that the first distance measuring sensor 810 generally adopts a laser distance measuring sensor or an ultrasonic distance measuring sensor. Taking the laser distance measuring sensor as an example, the laser distance measuring sensor emits a laser pulse toward the top wall of the rectangular frame 10, and part of the laser is reflected back to the receiving end of the laser distance measuring sensor. The time from the emission of the laser pulse to the return is recorded and processed, and the distance between the transmitting end of the laser distance measuring sensor and the top wall of the rectangular frame 10 can be measured, thereby providing information for the required movement of the top shaping plate 500.
[0037] See also Figure 2 In some embodiments of the utility model, the detection unit 800 also includes a second ranging sensor 820, and the second ranging sensor 820 and the first ranging sensor 810 are arranged at intervals in the front-to-back direction, and the transmitting end and the receiving end of the second ranging sensor 820 are vertically downward, and the top shaping plate 500 located above is penetrated by a second through hole 520, and the second through hole 520 is aligned with the transmitting end and the receiving end of the second ranging sensor 820, and the distance between the second ranging sensor 820 and the first ranging sensor 810 is adapted to the length dimension of the rectangular frame 10. It should be noted that, although the cross-section of the rectangular frame 10 is rectangular, the length direction of the rectangular frame 10 extends along the front-to-back direction. In the length direction of the rectangular frame 10, the top wall of the rectangular frame 10 may be convex at one position and concave at another position. By using the second ranging sensor 820 and the first ranging sensor 810 to cooperate with each other, the upper top shaping plate 500 can be lowered a certain distance and the lower top shaping plate 500 can be raised a certain distance, and finally the top wall of the rectangular frame 10 can be trimmed to a horizontal position along the length direction of the rectangular frame 10.
[0038] See also Figure 1 In some embodiments of the utility model, the base 100 includes a bottom plate 110, a left plate 120, a right plate 130 and a top plate 140, the bottom plate 110, the left plate 120, the right plate 130 and the top plate 140 together form a square frame for accommodating the rectangular frame member 10, the lower pressing plate 200 is located above the bottom plate 110 and within the square frame, the first limiting surface is provided on the inner wall of the left plate 120, the second limiting surface is provided on the inner wall of the right plate 130, and the top shaping plate 500 moves up and down within the square frame. The shaping device with the above structure is conducive to high compactness, reducing volume and cost.
[0039] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
[0040] Although the embodiments of the present invention have been shown and described, those skilled in the art will appreciate that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the claims and their equivalents.
