Description

Technical Field

[0001] The present application relates to the technical field of stamping and welding equipment, and in particular to an all-in-one stamping and welding machine. Background Art

[0002] Stamping refers to a processing method in which a press and a die are used to apply external force to plates, strips, tubes and profiles to cause them to undergo plastic deformation or separation, thereby obtaining a workpiece (stamping part) of the desired shape and size. The stamping blanks are mainly hot-rolled and cold-rolled steel plates and strips.

[0003] Some pipe workpieces are made of sheet materials. A stamping machine is first used to stamp the sheet materials into cylindrical pipes with seams, and then welding equipment is used to weld the seams of the pipes to form seamless pipes. This requires that such workpieces be first stamped into pipes using stamping equipment, and then taken out of the die after stamping, and then welded using welding equipment. This requires that such workpieces be transferred back and forth between the stamping equipment and the welding equipment during the processing, which delays the processing time and affects the processing efficiency. Therefore, the present application proposes a self-powered stamping forming and welding all-in-one machine. Utility Model Content

[0029] In order to make the purpose, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application.

[0030] like Figure 1-Figure 8As shown, a self-powered stamping forming and welding integrated machine proposed in an embodiment of the present application includes: a base 1, a stamping seat 2 is provided at the top thereof, a first arc-shaped groove 3 is provided on the top of the stamping seat 2; the longitudinal section of the first arc-shaped groove 3 is semicircular, two vertical plates 4 are respectively arranged at the two ends of the top of the base 1, a cross bar 5 is slidably penetrated on the vertical plate 4, and movable plates 6 are provided at the opposite ends of the two cross bars 5. Preferably, the number of the cross bars 5 is two, and the opposite ends of the two movable plates 6 are provided with a second arc-shaped groove 7; when the two movable plates 6 are close to each other, a welding seam is provided between the two movable plates 6, and the two second arc-shaped grooves 7 are enclosed in a semicircular shape, a bracket 8 is arranged on the base 1, and a bracket 8 is provided on the top of the bracket 8 A hydraulic push rod 9 is provided, a rectangular frame plate 10 is provided at the piston end of the hydraulic push rod 9, a vertical rod 11 is provided on the opposite side of the inner wall of the rectangular frame plate 10, a slide plate 12 is slidably sleeved on the vertical rod 11, and the opposite sides of the slide plate 12 are respectively overlapped with the opposite sides of the inner wall of the rectangular frame plate 10, so as to limit the sliding of the slide plate 12, so that the slide plate 12 can only slide vertically but cannot rotate in a circle, and a resisting spring 13 sleeved on the vertical rod 11 is installed between the top of the slide plate 12 and the inner wall of the rectangular frame plate 10, and a cylinder 14 is provided on one side of the slide plate 12; a linkage member 15 is provided on the rectangular frame plate 10, and when the cylinder 14 is located in the first arc groove 3, the linkage member 15 drives the two movable plates 6 to approach each other;The welding mechanism 16 is arranged on the rectangular frame plate 10, and is used for welding the workpiece after stamping. When processing the metal workpiece, the metal sheet is first placed on the top of the two movable plates 6, and the sheet is aligned with the first arc groove 3. The hydraulic push rod 9 works, and its piston end drives the rectangular frame plate 10 to move downward, so that the cylinder 14 squeezes the sheet and drives the sheet to move downward into the first arc groove 3. The sheet is deformed by the manual cylinder 14, so that the sheet is completely fitted into the first arc groove 3 after deformation, so that the sheet is initially stamped to form a U shape, and its two ends remain upright. When the cylinder 14 is located in the first arc After the cylinder 14 is in the first arc groove 3, since the slide plate 12 is slidably arranged on the vertical rod 11, when the cylinder 14 is located in the first arc groove 3, the hydraulic push rod 9 continues to drive the rectangular frame plate 10 to move downward. When the rectangular frame plate 10 moves downward, the slide plate 12 slides upward along the vertical rod 11 and squeezes the spring 13, thereby compensating the downward movement space of the rectangular frame plate 10. When the rectangular frame plate 10 continues to move downward, the linkage 15 drives the two movable plates 6 to approach each other, and the movable plate 6 resists the vertical end of the plate, thereby forcing its vertical end to deform and fit the surface of the cylinder 14. As the two movable plates 6 approach each other, the vertical end of the plate is completely fitted into the cylinder 14. The surface of the column 14 is pressed twice, so that the plate is completely deformed to fit the cylinder 14, so that it forms a tubular workpiece with a seam, and then the seam is welded by the welding mechanism 16 to complete the processing. Preferably, the elastic stress of the resisting spring 13 is greater than the deformation stress of the plate. Only when the plate is deformed to fit the first arc groove 3 (the cylinder 14 is completely located in the first arc groove 3), the slide plate 12 can slide along the vertical rod 11, and the linkage member 15 starts to work. The overall structure of the device is that the plate is first preliminarily punched into a U shape through the first arc groove 3, and then punched twice through the two second arc grooves 7 to form it. The workpiece with seams is finally welded by the welding mechanism 16 to complete the processing. After the initial stamping and secondary stamping of the workpiece, the workpiece is always located on the cylinder 14, and can be directly welded without taking out the workpiece, reducing the delay time. At the same time, the workpiece is welded on the cylinder 14, so that it will not deform during the welding process, ensuring the processing quality of the workpiece. When the workpiece is welded, the hydraulic push rod 9 drives the rectangular frame plate 10 to move up and reset, and under the resistance force, the two movable plates 6 are pushed away in the opposite direction synchronously, and the cylinder 14 carries the workpiece out of the first arc groove 3 and the second arc groove 7, and the workpiece can be slid out. ;

[0031] like Figure 1 and Figure 2As shown, in some embodiments, the linkage member 15 includes two resistance rods 1501, and the two resistance rods 1501 are respectively arranged at two ends of one side of the rectangular frame plate 10, and the end of the resistance rod 1501 is constructed with a first inclined surface 1502. Preferably, the initial height of the first inclined surface 1502 is higher than the height of the cylinder 14, and the two movable plates 6 are constructed with a second inclined surface 1503, and the two second inclined surfaces 1503 are overlapped with the two first inclined surfaces 1502 respectively. When the cylinder 14 resists the plate to deform and fit into the first arc groove 3, the cylinder 14 is completely located in the first arc groove 3. Under the action of the counter-resistance force, the slide plate 12 moves up. At this time, the first inclined surface 1502 of the resistance rod 1501 overlaps with the second inclined surface 1503 on the movable plate 6. As the rectangular frame plate 10 continues to move downward, under the overlap of the first inclined surface 1502 and the second inclined surface 1503, the two movable plates 6 approach each other, thereby completing the secondary stamping forming.

[0032] like Figure 6 As shown, in some embodiments, a limit plate 17 is provided at one end of the cross bar 5 away from the movable plate 6, and a return spring 18 is installed between the limit plate 17 and the vertical plate 4 and is sleeved on the cross bar 5. When the two movable plates 6 approach each other, the limit plate 17 will squeeze the return spring 18. After the workpiece completes the initial stamping, the secondary stamping and the welding, the rectangular frame plate 10 can assist the two movable plates 6 to move away from each other during the upward movement process under the elastic force of the return spring 18, so that the cylinder 14 can drive the workpiece after processing to separate from the first arc groove 3 and the second arc groove 7 more smoothly.

[0033] like Figure 7 As shown, in some embodiments, the welding mechanism 16 includes a first electric push rod 1601 arranged on the rectangular frame plate 10, and the piston end of the first electric push rod 1601 is provided with a mounting plate 1602. When the first electric push rod 1601 works, its piston end can drive the mounting plate 1602 to move horizontally, and a second electric push rod 1603 is provided on the mounting plate 1602, and the piston end of the second electric push rod 1603 is provided with a welding gun 1604. When the second electric push rod 1603 works, its piston end can drive the welding gun 1604 to move longitudinally. Through the lateral movement and the longitudinal movement, not only the position of the welding gun 1604 can be adjusted, but also it makes it more convenient and effective when welding the workpiece, thereby ensuring the welding quality.

[0034] like Figure 2As shown, in some embodiments, a third electric push rod 19 is provided on the slide plate 12, and a ring plate 20 slidably mounted on the cylinder 14 is provided at the piston end of the third electric push rod 19. During the initial stamping, the third electric push rod 19 is in a retracted state, and the ring plate 20 fits the slide plate 12, so that the initial stamping, secondary stamping and welding of the workpiece are not affected. When the welding is completed, the third electric push rod 19 works, and its piston end extends to drive the ring plate 20 to move, thereby ejecting the welded workpiece out of the cylinder 14, making it more convenient and quick to take out the workpiece.

[0035] like Figure 8 As shown, in some embodiments, the punching seat 2 is provided with an insertion groove 21 on both sides opposite to each other, and an insertion rod 22 is movably inserted in the insertion groove 21. Preferably, the longitudinal sections of the insertion groove 21 and the insertion rod 22 are both constructed in a T shape, so that the insertion rod 22 can slide along the insertion groove 21, but cannot completely break away from the insertion groove 21. A buffer spring 23 is connected between the insertion rod 22 and the insertion groove 21. When the two movable plates 6 approach each other, the movable plate 6 will squeeze the insertion rod 22, forcing the insertion rod 22 to squeeze the buffer spring 23, thereby buffering the impact force of the two movable plates 6 on the cylinder 14, so as to improve the service life of the movable plate 6 and the cylinder 14. When welding is completed, the elastic force of the buffer spring 23 can also assist the two movable plates 6 to move away from each other, so that the cylinder 14 can drive the workpiece after processing to break away from the first arc groove 3 and the second arc groove 7 more smoothly.

[0036] like Figure 1 , Figure 2 and Figure 8 As shown, in some embodiments, positioning grooves 24 are provided on the tops of the two movable plates 6. When placing the plates, the plates can be placed in the two positioning grooves 24. The positioning grooves 24 are used to place and position the plates so that the seams of the plates are located directly above after the initial stamping and the secondary stamping, so that the welding mechanism 16 can weld the seams, thereby improving the welding quality.

[0037] like Figure 8 As shown, in some embodiments, rollers 25 are rotatably provided at the opposite ends of the two positioning grooves 24. When the plate is initially stamped, its two ends are deformed and rigidly overlapped with the relative degrees of the two movable plates 6. When the plate is secondary stamped, the two movable plates 6 are also rigidly overlapped with the two ends of the plate to produce deformation. The rollers 25 are provided to reduce the hard friction of the movable plates 6 on the surface of the plate during the initial stamping deformation and the secondary stamping deformation, thereby reducing the scratches caused by the resistance deformation, thereby improving the processing quality of the workpiece.

[0038] The above description of the disclosed embodiments enables those skilled in the art to implement or use the present application. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present application. Therefore, the present application will not be limited to the embodiments shown herein, but will conform to the widest scope consistent with the principles and novel features disclosed herein.
