[0024] To make the above-mentioned objects, features, and advantages of the present invention more clearly understood, the following detailed description of specific embodiments of the present invention is provided in conjunction with the accompanying drawings. The following description sets forth many specific details to facilitate a full understanding of the present invention. However, the present invention can be implemented in many other ways than those described herein, and those skilled in the art may make similar modifications without departing from the scope of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0025] It should be noted that when an element is referred to as being "fixed to" another element, it may be directly on the other element or there may be an intermediate element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be an intermediate element at the same time. In contrast, when an element is referred to as being "directly on" another element, there is no intermediate element. The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only."

[0026] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the art to which this invention pertains. The terms used herein in the specification of this invention are intended only to describe specific embodiments and are not intended to limit this invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0027] like Figures 1 to 4 As shown, an automatic shaping device for bent workpieces is characterized in that it includes a base plate 1, a first positioning block 2 and a second positioning block 3 are provided on the upper side of the base plate 1, a clamping structure 4 is provided between the first positioning block 2 and the second positioning block 3, an inner shaping structure 5 is provided on the inner side of the first positioning block 2, and an outer shaping structure 6 is provided on the outer side of the second positioning block 3.

[0028] When the workpiece to be detected is placed at a specific position, under the action of the pressing structure 4, the workpiece can be fixed. Under the action of the inner shaping structure 5 and the outer shaping structure 6, the shaping of the inner and outer sides of the workpiece can be completed. At this time, through the inner shaping structure 5 and the outer shaping structure 6, an automatic shaping process can be realized, thereby improving the work efficiency and the shaping accuracy.

[0029] At this time, the overall shape of the workpiece is "U-shaped", with a main side, and side sides are provided on both sides of the main side. It is necessary to ensure the perpendicularity between the main side and the side sides. During the production process of the workpiece, the side sides generally tend to tilt inward or outward. Therefore, it is necessary to shape the side sides so that the main side and the side sides maintain perpendicularity.

[0030] At this time, the pressing structure 4 is used to press the workpiece to be shaped and at the same time provide a positioning for the workpiece to prevent the workpiece from moving during the shaping process, thereby affecting the accuracy during the shaping process. Therefore, in this embodiment, the pressing structure 4 includes a moving block 41. The bottom plate 1 is provided with a through hole for the moving block 41 to move up and down. A pressing cylinder 42 for driving the moving block 41 to move up and down is provided on the lower side of the bottom plate 1. The side surface of the moving block 41 is provided with a first inclined groove 43 and a second inclined groove 44. A first sliding rod and a second sliding rod are provided in the first inclined groove 43 and the second inclined groove 44. The first sliding rod and the second sliding rod are respectively connected with a first pressing block 45 and a second pressing block 46. When the pressing cylinder 42 controls the moving block 41 to move up or down, the first pressing block 45 and the second pressing block 46 move toward or away from the first positioning block 2 and the second positioning block 3 respectively. Under the action of the pressing cylinder 42, the moving block 41 moves up and down. Since the side surface of the moving block 41 is provided with the first inclined groove 43 and the second inclined groove 44, therefore, through the first sliding rod and the second sliding rod, the first pressing block 45 and the second pressing block 46 can move horizontally on the upper side of the bottom plate 1, and then press the workpiece to be shaped at the side positions corresponding to the first pressing block 45 and the second pressing block 46.

[0031] At this time, in the initial state, there is a certain distance between the first pressing block 45 and the first positioning block 2 to facilitate the placement of the workpiece to be shaped. At this time, the piston rod of the pressing cylinder 42 is in the lowest position, and the upper side of the first inclined groove 43 inclines toward the middle position of the moving block 41, that is, the upper side of the first inclined groove 43 gradually inclines away from the first positioning hole direction. In this way, when the moving block 41 moves upward, the first sliding rod gradually moves toward the first positioning block 2 in the first inclined groove 43, so that the first pressing block 45 also moves toward the first positioning block 2, thereby completing the pressing of the corresponding workpiece.

[0032] Similarly, the second pressing block 46 also completes the pressing of the corresponding workpiece under the action of the pressing cylinder 42.

[0033] After the workpiece is pressed, the shaping process needs to be completed. At this time, the internal shaping structure 5 includes two internal shaping blocks 51 arranged side by side on the inner side of the first positioning block 2. The inner shaping blocks 51 are provided with an internal driving structure on the lower side to control the outward movement of the inner shaping blocks 51. The internal shaping structure 5 acts on the inner side of the workpiece. At this time, the length of the first positioning block 2 is adapted to the length of the inner side of the workpiece to be shaped. The internal shaping blocks 51 are located on the inner side of the workpiece to be shaped. Under the action of the internal driving structure, the internal shaping blocks 51 move, thereby pressing the two side edges of the workpiece outward from the inner side of the workpiece, so that the workpiece is shaped at the side positions, causing the side edges of the workpiece to deform outward.

[0034] Specifically, the internal drive structure includes an internal cylinder 52, the piston rod of which is connected to an internal push rod 53. The side of the internal push rod 53 is provided with an inner inclined groove 54. The side of the internal shaping block 51 is provided with an inner slide rod, which is located in the inner inclined groove 54. Furthermore, the internal shaping block 51 is provided with an inner shaping surface 511. When the internal shaping block 51 moves outward under the action of the internal cylinder 52, the inner shaping surface 511 abuts the inner side of the product to be shaped. Under the action of the internal cylinder 52, the internal push rod 53 moves up and down, thereby causing the internal shaping block 51 to move horizontally. During this movement, the shaped block abuts against the inner side of the workpiece, thereby deforming the side of the workpiece outward. In this case, it is suitable for shaping when the side of the workpiece is tilted inward.

[0035] The external shaping structure 6 is used to shape the side of the workpiece when it is tilted outward. Specifically, the external shaping structure 6 includes two external shaping blocks 61 arranged side by side on the outside of the second positioning block 3. The external shaping blocks 61 are provided with an external driving structure on the bottom side to control the inward movement of the external shaping blocks 61. In this way, the external shaping blocks 61 press against the side of the workpiece from the outside, causing the side to tilt inward, thereby deforming the side of the workpiece inward.

[0036] Specifically, the external drive structure includes an external cylinder 62, the piston rod of which is connected to an external push rod 63. The external push rod 63 has an external inclined groove 64 on its side. The external shaping block 61 has an external slide bar on its side, which is located in the external inclined groove 64. Furthermore, the external shaping block 61 has an external shaping surface 65 on the side near the second positioning block 3. The external shaping surface 65 is a protruding pressure portion. When the external shaping block 61 moves inward under the action of the external cylinder 62, the pressure portion abuts the outer side of the workpiece to be shaped. Under the action of the external cylinder 62, the external push rod 63 moves upward, causing the external shaping block 61 to move inward, and the external shaping surface 65 abuts against the side of the workpiece, thereby deforming the side of the workpiece. At this time, to prevent excessive deformation of the side, the external shaping portion mainly acts on the side near the main edge. At the same time, the inner side of the workpiece abuts against the second positioning block 3, so that the second positioning block 3 can also serve as a limiter, thereby completing the shaping of the side of the workpiece.

[0037] During the movement of the first pressing block 45, the second pressing block 46, the inner shaping block 51 and the outer shaping block 61 on the upper side of the base plate 1, in order to keep in contact with the upper side of the base plate 1 and maintain a straight line during the movement, in this embodiment, a plurality of limiting grooves are provided on the upper side of the base plate 1, and corresponding T-shaped sliders 7 are provided in the limiting grooves. The T-shaped sliders 7 are fixed to the corresponding first pressing block 45, the second pressing block 46, the inner shaping block 51 and the outer shaping block 61. The horizontal portion of the T-shaped slider 7 is located at the lower side of the base plate 1, and the width of the horizontal portion is greater than the width of the limiting groove. At this time, the T-block includes a vertical portion located in the limiting groove and a horizontal portion on the lower side of the base plate 1. The width of the vertical portion is slightly smaller than the width of the limiting groove. In this way, during the movement of the first pressure block 45, the second pressure block 46, the inner shaping block 51, and the outer shaping block 61, the stability of the movement can be maintained, that is, linear movement. At the same time, the width of the horizontal portion located at the lower side of the base plate 1 is greater than the width of the limiting groove. In this way, after the T-shaped slider 7 is fixed to the first pressure block 45, the second pressure block 46, the inner shaping block 51, and the outer shaping block 61, the first pressure block 45, the second pressure block 46, the inner shaping block 51, and the outer shaping block 61 are fitted on the upper side of the base plate 1 and slide, thereby ensuring the stability of the first pressure block 45, the second pressure block 46, the inner shaping block 51, and the outer shaping block 61 during the movement.

[0038] During the shaping process, in order to avoid excessive deformation, corresponding inner and outer limit structures are provided. The inner limit structure corresponds to the inner shaping structure 5, including an inner limit pin arranged on the outside of the workpiece, and the outer limit structure corresponds to the outer shaping structure 6, including an outer limit pin arranged on the inside of the workpiece. In this way, during the shaping process, the inner limit pin prevents the side of the workpiece from deforming too much outward, and the outer limit pin prevents the side of the workpiece from deforming too much inward. At this time, the inner and outer limit pins can be controlled separately by two cylinders, and they will only move upward to the upper side of the protruding bottom plate 1 when needed. When not in use, the inner and outer limit pins are located in the corresponding through holes provided in the bottom plate 1, which will not affect the use of other functions.

[0039] After shaping, the workpiece needs to be inspected. An L-shaped inspection jig 8 is provided on the upper side of the base plate 1. The L-shaped jig has two perpendicular horizontal and vertical edges. After shaping, the workpiece can be placed inside or outside the L-shaped jig to determine whether the main and side edges of the workpiece are perpendicular.

[0040] The technical features of the above-mentioned embodiments can be combined arbitrarily. In order to make the description concise, not all possible combinations of the technical features in the above-mentioned 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.

[0041] The above-described embodiments merely represent several implementations of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that a person skilled in the art would be able to make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements fall within the scope of protection of the present invention. Therefore, the scope of protection of the present utility model patent shall be determined by the appended claims.
