[0001] The invention relates to the technical field of stamping and forming, and in particular to a rib angle forming machine. Background Art

[0002] In many industrial manufacturing fields, ribs are widely used in various workpieces as key components to improve structural strength and stability. The angle forming quality of the ribs directly affects the overall mechanical properties and reliability of the workpiece.

[0003] At present, the existing rib angle forming is mainly done by direct forming with a punching machine. However, during operation, when the punching machine applies pressure to the workpiece to form the rib, the workpiece will undergo plastic deformation under the huge extrusion force, which will cause the thickness of the rib to become thinner. Since the main force-bearing part of the rib in actual use is usually the top bevel, the reduction in thickness directly leads to a reduction in the bearing capacity of this part, which will affect the service life of the workpiece and is not conducive to the long-term use of the workpiece. Summary of the invention

DETAILED DESCRIPTION

[0033] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0034] An embodiment of a rib angle forming machine of the present invention is as follows Figures 1 to 15 shown.

[0035] A reinforcing rib angle forming machine is used to form a reinforcing rib 101 on a workpiece 100, and includes a machine body 200, an upper mold 300, and a lower mold 400. The upper mold 300 and the lower mold 400 are sequentially arranged on the machine body 200 along a first direction, the first direction is a vertical direction, and the upper mold 300 is located above the lower mold 400, and the upper mold 300 can move downward to close the mold with the lower mold 400. Specifically, a hydraulic system is provided on the machine body 200, and the hydraulic system can drive the upper mold 300 to move up and down. The hydraulic system is a prior art and will not be described in detail.

[0036] The upper mold 300 includes a plurality of upper extrusion blocks 310 arranged in sequence along a second direction, the second direction is perpendicular to the first direction, the second direction is a horizontal direction, and a molding groove is defined between two upper extrusion blocks 310 adjacently arranged in the second direction. The lower mold 400 includes a plurality of lower extrusion blocks 410 and a plurality of molding mechanisms 420 arranged in sequence along the second direction, and the lower extrusion blocks 410 and the molding mechanisms 420 are alternately distributed in sequence in the second direction.

[0037] Multiple upper extrusion blocks 310 and multiple lower extrusion blocks 410 are arranged one-to-one in the first direction, multiple molding grooves and multiple molding mechanisms 420 are arranged one-to-one in the first direction, and the molding mechanism 420 includes a base 421 and a molding block 422. The base 421 is square and fixedly arranged on the body 200, and the molding block 422 can move up and down on the base 421.

[0038] The downward movement of the upper mold 300 has a first stroke and a second stroke. In the first stroke, the upper end of the forming block 422 and the upper end of the base 421 are on the same plane. In the second stroke, the forming block 422 moves upward relative to the base 421 to extrude the workpiece 100.

[0039] Specifically, the upper extrusion block 310 is a conical block with a larger upper end and a smaller lower end, and the lower extrusion block 410 is provided with an extrusion groove for cooperating with the upper extrusion block 310 .

[0040] Specifically, a groove is formed on the base 421, and the forming block 422 is installed in the groove.

[0041] In this embodiment, an upper mold 300 and a lower mold 400 are provided. When in use, the upper mold 300 is driven to move downward to close the mold with the lower mold 400. In the first stroke of the upper mold 300 moving downward, the upper extrusion block 310 presses downward to bend the workpiece 100, and contacts and extrude the lower extrusion block 410 corresponding to it. Since the upper end of the forming block 422 and the upper end of the base 421 are on the same plane at this time, the base 421 cooperates with the forming groove to deform the workpiece 100, and the surface of the workpiece 100 is not squeezed by the forming block 422. Therefore, the workpiece 100 in this area will be flat under the restriction of the square end face of the base 421. Fig.10 To Attachment Fig.12 shown.

[0042] As the upper mold 300 continues to move, in the second stroke of the upper mold 300 moving downward, the forming block 422 moves upward relative to the base 421 and contacts the lower surface of the workpiece 100. After the upper extrusion block 310 and the lower extrusion block 410 are molded together, the workpiece 100 is also processed by the forming block 422 to complete the reinforcing rib 101. Fig.13 To Attachment Fig.15 shown.

[0043] That is, in the first stroke, the base 421 is used as the main molding part to perform plane extrusion on the workpiece 100. This setting can weaken the stretching degree of the main stress-bearing part (the beveled part) during the molding process of the reinforcing rib 101, thereby ensuring the strength of the reinforcing rib 101 after molding. After the plane extrusion is completed, in the second stroke, the molding block 422 is used as the main molding part to complete the final molding of the reinforcing rib 101, increase the area of ​​the main stress-bearing part of the reinforcing rib 101, and by dividing the movement of the upper mold 300 into two strokes, the overall bearing capacity of the reinforcing rib 101 is improved, thereby improving the service life of the workpiece 100.

[0044] In this embodiment, the molding mechanism 420 also includes a push assembly, which includes two push rods 423 and two push blocks 424. The two push rods 423 are arranged in a one-to-one correspondence with the two push blocks 424. The two push rods 423 are arranged in parallel in the third direction. The push rods 423 can slide up and down on the molding blocks 422. The two push blocks 424 are arranged in parallel in the third direction and can slide on the machine body 200 along the third direction. The third direction is perpendicular to the first direction and the second direction respectively. In the first stroke of movement of the upper mold 300, the distance from the upper end of the push rod 423 to the upper extrusion block 310 along the first direction is smaller than the distance from the base 421 to the upper extrusion block 310 along the first direction, and the push rod 423 remains stationary; in the second stroke of movement of the upper mold 300, the push rod 423 can move downward, and when the two push rods 423 slide downward, the two push blocks 424 can approach each other in the third direction and prompt the molding block 422 to move upward relative to the base 421 to extrude the workpiece 100.

[0045] Specifically, two slideways are provided on the machine body 200, and both slideways are arranged along the third direction. The two slideways are arranged in one-to-one correspondence with the two pushing blocks 424, and each pushing block 424 is slidably installed in the corresponding slideway.

[0046] In this embodiment, each push rod 423 is provided with a first wedge surface at the lower end, each push block 424 is provided with a second wedge surface and a third wedge surface, and the molding block 422 has two fourth wedge surfaces at the lower end. The second wedge surfaces on the two push blocks 424 are away from each other in the third direction, and the third wedge surfaces on the two push blocks 424 are close to each other in the third direction. The two first wedge surfaces are arranged in a one-to-one correspondence with the two second wedge surfaces, and the first wedge surfaces are connected to the second wedge surfaces corresponding to them, so that when the two push rods 423 slide downward, the two push blocks 424 can approach each other in the third direction. The third wedge surfaces on the two push blocks 424 are arranged in a one-to-one correspondence with the two fourth wedge surfaces at the lower end of the molding block 422, and the third wedge surfaces are connected to the fourth wedge surfaces corresponding to them, so that when the two push blocks 424 are close to each other in the third direction, the molding block 422 can move upward relative to the base 421 to press the workpiece 100.

[0047] Specifically, the molding block 422 includes a first molding segment 4221, a second molding segment 4222, a third molding segment 4223 and a fourth molding segment 4224. The first molding segment 4221, the second molding segment 4222, the third molding segment 4223 and the fourth molding segment 4224 are arranged in sequence in the first direction and fixedly connected. The first molding segment 4221 is located above the second molding segment 4222. The first molding segment 4221 is a conical structure with a small upper end and a large lower end. The second molding segment 4222 is a rectangular structure. The third molding segment 4223 is a rectangular structure, and the size of the third molding segment 4223 is smaller than that of the second molding segment 4222. The cross-section of the fourth molding segment 4224 perpendicular to the second direction is a trapezoid. The two fourth wedge-shaped surfaces are both located on the fourth molding segment 4224.

[0048] Furthermore, the forming block 422 is mounted on the machine body 200 through a first elastic member 425, which is arranged along the first direction and is a spring. A plurality of first elastic members 425 are provided, and four are provided in particular. By providing the first elastic member 425, after the workpiece 100 is processed, when the upper mold 300 moves upward relative to the lower mold 400 to reset, the forming block 422 can automatically reset under the urging of the first elastic member 425.

[0049] In this embodiment, by providing a push rod 423 and a push block 424, in the first stroke of the upper mold 300, when the stamping starts, the upper extrusion block 310 stamps downward to bend the workpiece 100, and the surface of the workpiece 100 is stamped into a V-shaped structure. Since the lower end of the V-shaped structure is relatively low, the lower end of the V-shaped structure will first contact the middle of the forming block 422, that is, when the upper extrusion block 310 just contacts the workpiece 100 and stamps the workpiece 100, the workpiece 100 is uniformly stamped into a V-shape and is in contact with the forming block 422. The workpiece 100 contacts the middle of the forming block 422, and because the upper end of the forming block 422 and the upper end of the base 421 are on the same plane at this time, the lower end of the workpiece 100 will also contact the base 421 synchronously. Therefore, even if the distance from the upper end of the push rod 423 to the upper extrusion block 310 along the first direction is smaller than the distance from the base 421 to the upper extrusion block 310 along the first direction, that is, the size of the push rod 423 in the first direction is larger than the size of the base 421 in the first direction, the workpiece 100 does not contact the push rod 423. As the upper extrusion block 310 continues to move downward, the base 421 will cooperate with the forming groove to deform the workpiece 100, so that the workpiece 100 is flat under the restriction of the square end surface of the base 421.

[0050] In the second stroke of the upper mold 300, the upper extrusion block 310 continues to move downward to stamp the workpiece 100, which will cause the workpiece 100 to squeeze the push rod 423, allowing the push rod 423 to move downward. The movement of the push rod 423 will cause the first wedge surface to move downward along the second wedge surface, thereby causing the two push blocks 424 to approach each other in the third direction. At this time, the third wedge surface and the fourth wedge surface cooperate to prompt the forming block 422 to move upward, deform the first elastic member 425, and extrude the workpiece 100 to complete the forming of the reinforcing rib 101.

[0051] In this embodiment, two pushing assemblies are provided, and the two pushing assemblies are arranged side by side in the second direction.

[0052] Alternatively, the two pushing blocks 424 arranged side by side in the second direction are fixedly connected to form an integrally formed structure.

[0053] Specifically, the forming block 422 is provided with a plurality of push grooves, which are arranged along the first direction, and the plurality of push grooves are arranged in one-to-one correspondence with the plurality of push rods 423 , and each push rod 423 is slidably installed in the corresponding push groove.

[0054] In another possible embodiment, the two end surfaces of the base 421 along the second direction are called molding surfaces 426 . The molding surfaces 426 are arc surfaces, and the convex side of the molding surfaces 426 is arranged along the second direction toward the molding block 422 .

[0055] By setting the molding surface 426 on the base 421 as an arc surface, when the upper extrusion block 310 and the lower extrusion block 410 are molded, the lower end of the upper extrusion block 310 contacts the workpiece 100 to bend the workpiece 100. When the workpiece 100 is extruded onto the two molding surfaces 426, the molding surfaces 426 can make the deformation area of ​​the workpiece 100 larger, so that the inclined surface area of ​​the workpiece 100 reinforcement 101 after molding can be expanded, thereby increasing the force-bearing area of ​​the reinforcement 101 and further improving the overall strength of the reinforcement 101.

[0056] In combination with the above embodiments, the specific working process is as follows:

[0057] When in use, the upper mold 300 is driven to move downward to close the mold with the lower mold 400. In the first stroke of the upper mold 300, when the stamping starts, the upper extrusion block 310 stamps downward to bend the workpiece 100, and the surface of the workpiece 100 is stamped into a V-shaped structure. Since the lower end of the V-shaped structure is relatively low, the lower end of the V-shaped structure will first contact the middle of the forming block 422, that is, when the upper extrusion block 310 just contacts the workpiece 100 and stamps the workpiece 100, the workpiece 100 is uniformly stamped into a V-shape, and The workpiece 100 contacts the middle of the forming block 422. Since the upper end of the forming block 422 and the upper end of the base 421 are in the same plane at this time, the lower end of the workpiece 100 will also contact the base 421 synchronously. Therefore, even if the distance from the upper end of the push rod 423 to the upper extrusion block 310 along the first direction is smaller than the distance from the base 421 to the upper extrusion block 310 along the first direction, that is, the size of the push rod 423 in the first direction is larger than the size of the base 421 in the first direction, the workpiece 100 does not contact the push rod 423. As the upper extrusion block 310 continues to move downward, the base 421 will cooperate with the forming groove to deform the workpiece 100, so that the workpiece 100 is flat under the restriction of the square end surface of the base 421. See the attached Fig.10 To Attachment Fig.12 shown.

[0058] As the upper mold 300 continues to move, in the second stroke of the upper mold 300, the upper extrusion block 310 continues to move downward to stamp the workpiece 100, which will cause the workpiece 100 to squeeze the push rod 423, so that the push rod 423 can move downward. The movement of the push rod 423 will cause the first wedge surface to move downward along the second wedge surface, thereby causing the two push blocks 424 to approach each other in the third direction. At this time, the third wedge surface and the fourth wedge surface cooperate to cause the forming block 422 to move upward, deform the first elastic member 425, and extrude the workpiece 100. After the upper extrusion block 310 and the lower extrusion block 410 are molded together, the reinforcing rib 101 is formed. Refer to the attached Fig.13 To Attachment Fig.15 shown.

[0059] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
