[0001] The invention relates to metal sheet processing equipment, in particular to a thin-wall metal sheet edge forming machine. Background Art

[0002] At present, the bending equipment in the prior art can only perform one bend on the side of the metal plate in each working cycle, and cannot complete the secondary bending of the side of the metal plate at the same time. When the metal plate needs a secondary bend, due to the limitation of the bending equipment, it can only be manually adjusted for the secondary operation. The types of cutting and bending are very limited due to the limitation of the mold, the manual correction accuracy is poor, and the operation is dangerous and the work efficiency is low. Therefore, the technicians in this field provide a thin-walled metal plate bend machine to solve the above technical problems. Summary of the invention

A fixed plate is arranged above the base, and a cold pressing space is formed between the two. A primary die edge template is arranged on the base, that is, inside the cold pressing space. A discharge template is arranged on one side of the primary die edge template, and the discharge template is installed on the base through a telescopic spring, and is arranged closely with the primary die edge template to form a structure that can move up and down closely with the primary die edge template. A secondary die edge template is slidably arranged on the primary die edge template, and the two die edge templates form a step on the side close to the discharge template, that is, one side of the secondary die edge template is arranged backward and forms a die edge space with one side of the primary die edge template. A horizontal hydraulic cylinder is arranged on the other side of the secondary die edge template, and the horizontal hydraulic cylinder is fixed on the base, and its piston rod is connected with the secondary die edge template to push the secondary die edge template to move forward and backward. A cold pressing part is movably arranged below the fixed plate, that is, in the upper part of the cold pressing space. A vertical hydraulic cylinder is arranged on the fixed plate. The piston rod of the vertical hydraulic cylinder passes through the fixed plate and is connected to the cold pressing part to push the cold pressing part to move up and down. The lower part of the cold pressing part is a pressing head. The outer surface of the front side of the pressing head and the front side of the discharge template, that is, the outer surface of the side of the primary socket template are in the same vertical plane, and a socket groove body is provided at the lower part of the front side of the pressing head. When the pressing head compacts the discharge template, the upper surface of the lower groove side of the socket groove body is not higher than the upper surface of the primary socket template, and the height of the socket groove body is greater than the thickness of the secondary socket template.

DETAILED DESCRIPTION

[0011] Now, with reference to the accompanying drawings of the specification, combined with specific embodiments, the following description is given: A thin-walled metal plate edge machine according to the present invention comprises a base 1, a fixing plate 2, a primary edge template 3, a discharge template 4, a secondary edge template 6 and a cold pressing part 8. Figure 1On the base 1, support columns are respectively arranged at its four diagonal points, and a fixing plate 2 is connected through the above support columns. The fixing plate 2 is located above the base 1, and a cold pressing space is formed between the two. On the base 1, that is, inside the cold pressing space, a primary nest edge template 3 is arranged. A discharge template 4 is arranged on one side of the primary nest edge template 3, and the discharge template 4 is installed on the base 1 through a telescopic spring 5, one end of the telescopic spring 5 is connected to the discharge template 4, and the other end is connected to the base 1. The discharge template 4 is arranged closely to the primary nest edge template 3 to form a structure that can move up and down closely to the primary nest edge template 3. A secondary nest edge template 6 is slidably arranged on the primary nest edge template 3, and the two nest edge templates form a step on the side close to the discharge template 4, that is, one side of the secondary nest edge template 6 is arranged backward and forms a nest edge space with one side of the primary nest edge template 3. A horizontal hydraulic cylinder 7 is provided on the other side of the secondary socket template 6. The horizontal hydraulic cylinder 7 is fixed on the base 1, and its piston rod is connected to the secondary socket template 6 through a connecting piece to push the secondary socket template 6 to move forward and backward. A cold pressing part 8 is movably provided below the fixed plate 2, that is, in the upper part of the cold pressing space. A vertical hydraulic cylinder 9 is provided on the fixed plate 2. The piston rod of the vertical hydraulic cylinder 9 passes through the fixed plate 2 and is connected to the cold pressing part 8 to push the cold pressing part 8 to move up and down. The lower part of the cold pressing part 8 is a pressing head 10. The outer surface of the front side of the pressing head 10 is in the same vertical plane as the front side of the discharge template 4, that is, the outer surface of the side of the primary socket template 3, and a socket groove 11 is provided at the lower part of the front side of the pressing head 10. When the pressing head 10 compacts the discharge template 4, the upper surface of the lower groove edge of the socket groove 11 is not higher than the upper surface of the primary socket plate 3, and the height of the socket groove 11 is greater than the thickness of the secondary socket template 6.

[0012] The working principle of the present invention is as follows: the worker places the metal plate on the discharge template 4, and places one side of the metal plate, that is, the side that needs to be edged, on the step formed by the primary edged template 3 and the secondary edged template 6, that is, in the edged space. Before the operation, the worker can adjust the distance between the front side of the secondary edged template 6 and the front side of the primary edged template 3 by adjusting the telescopic length of the piston rod of the horizontal hydraulic cylinder 7, so that the edged space corresponds to the edged size of the metal plate. After the metal plate is fixed, the vertical hydraulic cylinder 9 will push the cold pressing part 8 downward during the extension process. The cold pressing part 8 keeps moving downward, and when its pressing head 10 contacts the metal plate, the pressing head 10 cooperates with the primary edged template 3 to start the first edged. The pressing head 10 continues to move downward, and when the pressing head 10 compacts the discharge template 4, it touches the limit switch and stops moving downward, that is, the vertical hydraulic cylinder 9 stops working. At this time, the metal plate has completed the first folding edge, i.e., the primary hemming. The upper surface of the lower groove edge of the hemming groove body 11 of the pressing head 10 is just flush with the upper surface of the primary hemming template 3, that is, the height of the lower groove edge of the hemming groove body 11, the height of the material discharge template 4, and the thickness of the material plate are equal to the height of the primary hemming template 3. After the primary hemming is completed, the horizontal hydraulic cylinder 7 is automatically started. During the extension process of the horizontal hydraulic cylinder 7, the secondary hemming template 6 is pushed forward. The secondary hemming template 6 moves forward all the time. When its front side contacts the primary hemming of the metal plate, it cooperates with the hemming groove body 11 of the pressing head 10 to start the second hemming. The secondary hemming template 6 extends into the hemming groove body 11 and touches the limit, i.e., the horizontal hydraulic cylinder 7 stops working, and the secondary hemming is completed. At this time, the primary hemming of the metal plate has completed an angle of hemming, and the second angle of hemming is completed. The above process is a complete process of the primary and secondary hemming of one side of the metal plate.

[0013] Further, see Figure 3 The lower surface of the discharge template 4 is provided with a plurality of upper blind holes, the upper surface of the base 1 is provided with lower blind holes corresponding to the upper blind holes, the top end of the telescopic spring 5 is provided in the upper blind hole, and the bottom end thereof is provided in the lower blind hole.

[0014] Further, see Figure 4 The upper surface of the material discharging template 4 is also provided with guide plates 12 on both sides thereof. The spacing between the two guide plates 12 can be adjusted to correspond to the width of the metal plate. The guide plates 12 are provided with a transparent adjustment slot 17. The adjustment slot 17 is provided with a fixing bolt, which is screwed to the material discharging template 4. In actual operation, workers can loosen the fixing bolts to adjust the spacing between the two guide plates 12 through the adjustment slot 17 to correspond to the width of the metal plate. After the adjustment is completed, tighten the fixing bolts to fix the positions of the two guide plates 12.

[0015] Furthermore, a limiting block 13 is provided on the other side of the discharge template 4 and is closely attached to the discharge template 4 , and the limiting block 13 is fixed on the base 1 .

[0016] Furthermore, guide rods 14 are respectively provided on both sides of the cold pressing part 8, the bottom ends of which are connected to the base 1. The cold pressing part 8 is penetrated and slidably arranged on the guide rods 14 to ensure the direction of the cold pressing part when it moves up and down.

[0017] For further information, see Figure 2 The two sides of the secondary nest edge template 6 are respectively provided with slideways 15, and the slideways 15 are slidably fitted with the primary nest edge template 3. A limiting plate 16 is provided inside the slideway 15, that is, above the secondary nest edge template 6. The upper side of the slideway 15 is screwed with a limiting bolt, and the limiting bolt can make the limiting plate 16 close to the secondary nest edge template 6. By providing the limiting plate 16 and the limiting bolt, the slideway 15 can adapt to the secondary nest edge templates 6 of different thicknesses.
