Description

Technical Field

[0001] The utility model relates to the field of stainless steel processing auxiliary components, in particular to a turnover type bending device for stainless steel processing. Background Art

[0002] Stainless steel sheets have high strength and hardness, as well as good plasticity and toughness. They are divided into two types according to the manufacturing method: hot rolling and cold rolling. At present, products made of stainless steel sheets are widely used in life. In the processing of stainless steel sheets, they are often bent as needed to obtain steel parts of the required shape. For example, right-angle steel parts can be obtained by flip-bending, and such right-angle steel parts are usually used in the production process of stainless steel frames.

[0003] Specifically, in the process of bending the stainless steel sheet, the common operation is usually: placing the stainless steel sheet flat on the top surface of the V-bending die, and then bending the stainless steel sheet by pressing down the punch of the V-bending die and cooperating with the bending groove of the die. In the bending process, the two sides of the stainless steel sheet will flip toward the bending position in the middle. Since the upward flipping process of the two sides of the stainless steel sheet is only driven by the bending position descending toward the bottom of the bending groove, creases are easily generated at the edge of the stainless steel sheet and the top of the bending groove, which seriously affects the appearance quality of the product, and also affects the later surface coating or electroplating anti-corrosion layer of the product.

[0019] By using the above-mentioned flip-type bending equipment for stainless steel processing, specifically in the process of flipping the stainless steel sheet to make a right-angle steel part through bending, the stainless steel sheet is placed flat on the top surface of the die body, and the side support components on both sides of the operating table body can support the bottom surfaces of the stainless steel sheet on both sides, and in the bending process, the top support plate can be attached to and supported on the bottom surface of the stainless steel sheet in real time by rising and flipping, and a certain force can be applied to the upward flipping of the stainless steel sheet from the lateral position, so that the stainless steel sheet can be guided to smoothly realize the process of flipping upwards on both sides during the bending process, which is conducive to preventing the stainless steel sheet from being bent against the edge position of the top of the bending groove. The support plate is locked by the magnetic attraction of the end head at the bottom end of the support rod and the electromagnet body on the top surface of the storage plate, and the locking method of the support plate position height is simple and easy to implement, which makes it easy to smoothly place the stainless steel plate to be bent on the top surface of the die body. When the male die body descends to contact the stainless steel plate for bending, the locking of the support plate that cannot rise can be released by powering off the electromagnet body to end the magnetic attraction state. The unlocking method of the support plate position height is simple and easy to implement, which makes it easy for the support plate to smoothly rise and flip The stainless steel sheet is then supported from the side. Specifically, during the operation, the stainless steel sheet is placed flat on the top surface of the die body and the bending position is aligned with the bottom direction of the bending groove. Both sides of the bottom surface of the stainless steel sheet are then placed flat on the top surface of the support plate and supported by the top surface of the support plate, so that the hydraulic cylinder body works by connecting to the external oil supply pipeline. The hydraulic cylinder body drives the die base and the punch body to descend by extending the push rod. During the descending process, the punch body will first descend to the bending position on the top surface of the stainless steel sheet. At this time, the electromagnet body is powered off to release the suction of the end head. The spring can release its own stretched state at any time to drive the support plate to close The push rod of the hydraulic cylinder body continues to drive the punch body to descend and bends the stainless steel sheet with the bending position as the center line by adapting the lower part of the punch body to the bending groove. During the bending process, the two sides of the stainless steel sheet are located at the bending position as the axis and are both flipped upward. During the flipping process of the two sides of the stainless steel sheet, the spring will release its own tension state in real time and drive the support plate to push up the side of the stainless steel sheet. Moreover, during the process of the support plate pushing up the side of the stainless steel sheet, the support plate can be smoothly flipped to the top surface by rotating the hinge seat around the rotating shaft so as to be attached to and contact the side bottom of the stainless steel sheet in real time.The support plate can be attached to and supported on the bottom surface of the stainless steel plate in real time by rising and flipping at the same time, and a certain force can be applied to the upward flipping of the stainless steel plate from the lateral position, thereby guiding the stainless steel plate to smoothly realize the process of flipping upward at both sides during the bending process, thereby preventing creases from being generated at the edge positions of the stainless steel plate and the top of the bending groove. Specifically, in the process of the stainless steel plate being bent by the punch body as the push rod descends, the descending process of the punch body is accurately positioned and guided by the guide stud in the process of vertically sliding along the guide hole, and at the same time, the limiting nut on the periphery of the guide stud is released from the top surface of the U-shaped frame, so that the lowest position of the descent of the punch body can be safely limited, and then the punch body can be prevented from descending too low and damaging the bending position of the stainless steel plate by limiting the lowest descending position of the punch body, which is beneficial to further improve the product quality of the stainless steel plate after bending. The method can adjust the vertical position height of the limit nut, and then adjust the limit nut to a suitable safety limit position according to the thickness of the stainless steel plate to be bent, thereby improving the adaptability and flexibility during use. Specifically, in operation, when the position height of the limit nut is adaptively adjusted, when the top surface of the die body is not placed with a stainless steel plate, the hydraulic cylinder body drives the punch body to drop to the lower part through the push rod to fully adapt to the bending groove and then remain motionless, and then the limit nuts are screwed down to contact the top surface of the U-shaped frame, and then the limit nuts are screwed up to rise until the distance between the bottom surface of the limit nut and the top surface of the U-shaped frame is equal to the thickness of the stainless steel plate to be bent. The distance between the bottom surface of the limit nut and the top surface of the U-shaped frame can be compared and adjusted by horizontally padding the stainless steel plate to be bent. In this way, the adaptive adjustment of the position height of the limit nut is completed, and the limit nut is adjusted to a suitable safety limit position.

[0020] The beneficial effects are as follows: 1. After the stainless steel sheet is placed flat on the top surface of the die body, the side support components on both sides of the operating table body can support the bottom surfaces of the stainless steel sheet on both sides, and in the bending process, the top support plate can be attached to and supported on the bottom surface of the stainless steel sheet in real time by rising and flipping, and a certain force can be applied to the upward flipping of the stainless steel sheet from the lateral position, and then the stainless steel sheet can be guided to smoothly realize the process of flipping upward at both sides during the bending process, which is conducive to preventing the stainless steel sheet from generating creases at the edge position of the bending groove top and improving the product quality of the stainless steel sheet after bending;

[0021] 2. When the support plate is lowered to the top surface and is level with the top surface of the die body, the position height of the support plate can be locked by magnetic attraction between the end of the bottom end of the support rod and the electromagnet body on the top surface of the storage plate. The locking method of the support plate position height is simple and easy to implement, which makes it easy to smoothly place the stainless steel sheet to be bent on the top surface of the die body. When the punch body descends to contact the stainless steel sheet for bending, the lock on the support plate that cannot rise can be released by turning off the power of the electromagnet body to end the magnetic attraction state. The unlocking method of the support plate position height is simple and easy to implement, which makes it easy to smoothly allow the support plate to rise and flip while supporting the stainless steel sheet on the side.

[0022] 3. When the punch body is bent along with the push rod, the guide stud can accurately guide the descending process of the punch body by sliding vertically along the guide hole. At the same time, the limit nut on the periphery of the guide stud can be released from the top surface of the U-shaped frame to safely limit the lowest position of the punch body. Then, by limiting the lowest position of the punch body, the punch body can be prevented from descending too low and damaging the bending position of the stainless steel plate, which is conducive to further improving the product quality of the stainless steel plate after bending.

[0023] 4. The vertical position height of the limit nut can be adjusted by turning the limit nut, and then the limit nut can be adjusted to a suitable safety limit position according to the thickness of the stainless steel plate to be bent, thereby improving the adaptability and flexibility during use.

[0040] In order to make the purpose, technical solution and advantages of the utility model clearer, the technical solution of the utility model will be described in detail below. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other implementation methods obtained by ordinary technicians in this field without creative work belong to the scope of protection of the utility model.

[0041] See also Figure 1-Figure 13 As shown, the utility model provides a flip-type bending equipment for stainless steel processing, including an operating table body 2, a die body 5 and a punch body 4 for flip-bending the stainless steel plate, a bottom cabinet 201 for supporting the elevation is fixedly installed on the bottom surface of the operating table body 2, a die body 5 is fixedly installed in the middle of the top surface of the operating table body 2, and a bending groove 501 on the top of the die body 5 is arranged along the longitudinal direction. The operating table body 2 is provided with side support components 6 on both sides of the die body 5 for supporting the side bottom surface of the stainless steel plate during the bending process. Specifically, the side support components 6 include mounting holes 609, support poles 604 and electromagnet bodies 608. The operating table body 2 is provided with mounting holes 609 vertically between the side of the U-shaped frame 104 and the side of the die body 5. The mounting holes 609 are through holes, and the mounting holes 609 are vertically inserted with support poles 604 in a coaxial sliding manner. The top of the support poles 604 is longitudinally inserted with a rotating shaft 603, and the front and rear ends of the rotating shaft 603 are rotatably connected with an articulated seat 602, and the top surfaces of the articulated seats 602 at the same side are fixed to the bottom surface of the support plate 601 horizontally arranged on the same side, and the bottom ends of the support poles 604 extending into the bottom cabinet 201 are coaxially fixed with end heads 607. The portion of the vertical rod 604 located between the bottom surface of the operating table body 2 and the bottom surface of the end head 607 is coaxially gap-fitted with a spring 606, and both ends of the spring 606 are fixedly connected to the corresponding end head 607 and the bottom surface of the operating table body 2, and the electromagnet bodies 608 are fixedly installed on both sides of the top surface of the storage plate 203, and the top surfaces of the electromagnet bodies 608 are magnetically fixed to the bottom surfaces of the corresponding side ends 607. The purpose of this arrangement is that during the bending process, the side support components 6 on both sides of the operating table body 2 can support the bottom surfaces of the stainless steel plate on both sides, and at the same time, the top support plate 601 can be attached to and supported on the bottom surface of the stainless steel plate in real time by rising and flipping, and a certain force can be applied to the upward flipping of the stainless steel plate from the lateral position, thereby guiding the stainless steel plate to smoothly realize the process of flipping upward on both sides during the bending process.

[0042] At the same time, specifically in the process of setting the support plate 601 and the electromagnet body 608, when the support plate 601 descends to the top surface and is level with the top surface of the die body 5, the position height of the support plate 601 can be locked by magnetic attraction between the end 607 at the bottom of the support rod 604 and the electromagnet body 608 on the top surface of the storage plate 203, so that it is convenient to smoothly place the stainless steel sheet to be bent on the top surface of the die body 5. When the punch body 4 descends to contact the stainless steel sheet for bending, the electromagnetic body 608 is powered off to end the magnetic attraction state, so that the lock on the support plate 601 that cannot rise can be released, so that the support plate 601 can be smoothly raised and flipped to support the side of the stainless steel sheet.

[0043] See also Figure 1-Figure 2 As shown, a bending force-applying component 1 for applying force to the stainless steel plate during the bending process is installed above the top surface of the operating table body 2, and the bottoms of both sides of the bending force-applying component 1 are respectively fixed to the two sides of the top surface of the operating table body 2, and a punch body 4 is installed at the bottom end of the middle part of the bending force-applying component 1 along the longitudinal direction, and the lower part of the punch body 4 is directly opposite to the bending groove 501 up and down and can be adapted to each other. Preferably, the cross-sectional shape of the lower part of the punch body 4 and the bending groove 501 along the transverse vertical plane is V-shaped, so that a right-angled steel part can be obtained through a bending operation. Specifically, the bending force-applying component 1 includes a U-shaped frame 104 and a hydraulic cylinder body 101, the U-shaped frame 104 is inverted and the bottom ends of the vertical parts at both sides are respectively fixed to the two sides of the top surface of the operating table body 2 through connecting plates 105, and the horizontal part at the top of the U-shaped frame 104 A hydraulic cylinder body 101 is vertically fixed on a part of the top surface, and a push rod 106 at the bottom of the hydraulic cylinder body 101 passes through the top bottom surface of the U-shaped frame 104 in a vertical sliding fit manner, and the bottom end is fixed with a longitudinally arranged die base 103 through a mounting sleeve 102. Preferably, the mounting sleeve 102 is fixed to the bottom end of the push rod 106 by a coaxial interference fit, and the mounting sleeve 102 is welded to the top surface of the die base 103, so that the die base 103 and the push rod 106 can be quickly assembled and connected together through the mounting sleeve 102. A longitudinally arranged punch body 4 is fixedly installed on the lower part of the die base 103. Such a configuration makes it easy for the hydraulic cylinder body 101 to drive the push rod 106 to extend outward so that the push rod 106 drives the punch body 4 to descend to the lower part and adapt to the bending groove 501 of the die body 5, thereby realizing the bending process of the stainless steel plate.

[0044] See also Figure 1-Figure 7As shown, the front and rear positions of the bending force-applying component 1 are both installed with safety limit components 3 for safely limiting the lowest position of the descent of the punch body 4. Specifically, the safety limit components 3 include guide holes 305 and guide studs 302. The top of the U-shaped frame 104 is vertically provided with guide holes 305 at the front and rear positions of the hydraulic cylinder body 101. The guide holes 305 are all through holes and are vertically inserted with guide studs 302 in a coaxial sliding fit manner. The bottom ends of the guide studs 302 are fixed to the top surface of the die base 103 by connecting sleeves 304. Preferably, the connecting sleeves 304 are fixed to the bottom ends of the guide studs 302 by a coaxial interference fit. At the same time, the connecting sleeves 304 are welded to the top surface of the die base 103, so that the die base 103 and the guide studs 302 can be quickly assembled and connected together through the connecting sleeves 304, and the guide studs 302 can be quickly assembled and connected together through the connecting sleeves 304. The portion of the stud 302 that extends out of the top surface of the U-shaped frame 104 is coaxially engaged with the limiting nut 303. The advantage of such a configuration is that the descent process of the punch body 4 can be accurately positioned and guided by the guide stud 302 in the process of vertically sliding along the guide hole 305. At the same time, the limiting nut 303 on the periphery of the guide stud 302 is released from the top surface of the U-shaped frame 104, so that the lowest descent position of the punch body 4 can be safely limited. Then, by limiting the lowest descent position of the punch body 4, the punch body 4 can be prevented from descending too low and damaging the bending position of the stainless steel plate. Moreover, by turning the limiting nut 303, the vertical position height of the limiting nut 303 can be adjusted, and then the limiting nut 303 can be adjusted to a suitable safe limiting position according to the thickness of the stainless steel plate to be bent.

[0045] See also Figure 1-Figure 9 As shown, the operating table body 2, the bending force application component 1 and the safety limit component 3 are respectively optimized as follows. First, specifically in the operating table body 2, the front of the base cabinet 201 is open and cabinet doors 202 that can be opened and closed are installed on both sides by hinges, and a storage plate 203 is fixed and unfolded horizontally in the middle of the base cabinet 201. This arrangement makes it easy to perform regular inspection and maintenance of the electromagnet body 608 by opening the cabinet door 202, and at the same time, the electromagnet body 608 can be smoothly fixed and installed by setting the storage plate 203.

[0046] At the same time, specifically in the bending force assembly 1, the die base 103 is a U-shaped base and the punch body 4 is fixedly installed between the two sides of the bottom by means of transverse insertion of screws, so that the punch body 4 can be firmly and securely positioned between the two sides of the bottom of the die base 103, thereby ensuring that the punch body 4 can stably follow the die base 103 to descend for bending operations.

[0047] Specifically, in the safety limit assembly 3, the vertical length of the guide stud 302 is not less than the length of the hydraulic cylinder body 101, and the top of the guide stud 302 is coaxially fixed with an anti-dropping end plate 301. The purpose of this arrangement is to first ensure that the guide stud 302 has a sufficient length to guide and correct the descent process of the punch body 4, and at the same time ensure that the guide stud 302 has a sufficient length for the limit nut 303 to be screwed and adjusted, so that the lowest descending position of the punch body 4 can be safely limited smoothly. The limit nuts 303 are all hand-tightened knurled nuts. This arrangement makes it easy to screw the limit nuts 303 by hand to adjust the vertical lifting and lowering along the guide stud 302.

[0048] See also Figure 2-Figure 7 As shown, the side support assembly 6 is optimized as follows: when the electromagnet body 608 is energized and magnetically fixed with the corresponding end head 607, the spring 606 is in a stretched state, and the top surface of the support plate 601 is highly flush with the top surface of the die body 5; when the electromagnet is de-energized and separated from the corresponding end head 607, the spring 606 is restored to a free state, and the top surface of the support plate 601 is higher than the top surface of the die body 5. The effect of this arrangement is that when the electromagnet body 608 is magnetically connected with the end head 607, the top surface of the support plate 601 can be highly flush with the top surface of the die body 5, and the stainless steel plate can be smoothly placed flat. At the same time, when the electromagnet body 608 and the end head 607 are released from magnetic attraction, the spring 606 can be restored to a free state so that the support plate 601 can push up the side of the stainless steel plate.

[0049] At the same time, the rotating shaft 603 can be specifically selected to be longitudinally inserted through the top of the supporting upright 604 in a coaxial sliding manner, and the top of the supporting upright 604 is lower than the bottom surface of the corresponding support plate 601, the hinge seat 602 and the end of the corresponding rotating shaft 603 are movably riveted, and the outer end of the rotating shaft 603 passing through the hinge seat 602 is coaxially fixed with an anti-slip ring 605. This arrangement makes it easy for the support plate 601 to smoothly flip to the top surface and be in real time attached to and in contact with the bottom surface of the side of the stainless steel plate by rotating the hinge seat 602 around the rotating shaft 603 during the process of pushing the side of the stainless steel plate. It can be further selected that the support plates 601 are all rectangular plates and both sides do not contact the U-shaped frame 104 and the die body 5, and the end heads 607 are all iron round plates. The advantage of such a setting is that it can firstly prevent the support plates 601 from interfering with the U-shaped frame 104 and the punch body 4, while also ensuring that the end heads 607 can be smoothly magnetically attracted by the energized electromagnet body 608.

[0050] By adopting the above structure, specifically in the process of flipping and bending the stainless steel sheet to form a right-angle steel part, after the stainless steel sheet is placed flat on the top surface of the die body 5, the side support components 6 on both sides of the operating table body 2 can support the bottom surfaces of the stainless steel sheet on both sides, and in the bending process, the top support plate 601 can be attached and supported on the bottom surface of the stainless steel sheet in real time by rising and flipping, and a certain force can be applied to the upward flipping of the stainless steel sheet from the lateral position, and then the stainless steel sheet can be guided to smoothly realize the process of flipping upwards on both sides during the bending process, which is beneficial to prevent the stainless steel sheet from generating creases at the edge position of the top of the bending groove 501, thereby improving the product quality of the stainless steel sheet after bending. At the same time, when the support plate 601 drops to the point where the top surface is level with the top surface of the die body 5, the position height of the support plate 601 can be locked by magnetic attraction between the end 607 at the bottom of the support rod 604 and the electromagnet body 608 on the top surface of the storage plate 203. The locking method for the position height of the support plate 601 is simple and easy to implement, which makes it easy to smoothly place the stainless steel sheet to be bent on the top surface of the die body 5. When the punch body 4 drops to contact the stainless steel sheet for bending, the locking of the support plate 601 that cannot rise can be released by turning off the power of the electromagnet body 608 to end the magnetic attraction state. The unlocking method for the position height of the support plate 601 is simple and easy to implement, which makes it easy for the support plate 601 to smoothly rise and flip while bending the stainless steel sheet. Support, specifically in the operation, the stainless steel plate is placed flat on the top surface of the die body 5 and the bending position is aligned with the bottom direction of the bending groove 501. The bottom sides of the stainless steel plate are then placed flat on the top surface of the support plate 601 and supported by the top surface of the support plate 601, so that the hydraulic cylinder body 101 works by connecting with the external oil supply pipeline. The hydraulic cylinder body 101 drives the die base 103 and the punch body 4 to descend by extending the push rod 106. The process of the punch body 4 descending will first drop to the bending position of the top surface of the stainless steel plate. At this time, the electromagnet body 608 is powered off to release the suction of the end head 607. The spring 606 can release its own stretched state at any time to drive the support plate 601 to press tightly against the stainless steel plate. The push rod 106 of the hydraulic cylinder body 101 continues to drive the punch body 4 to descend and bends the stainless steel sheet with the bending position as the center line by adapting the lower part of the punch body 4 to the bending groove 501. During the bending process, the two sides of the stainless steel sheet are located at the bending position as the axis and are turned upward. During the upward turning process of the two sides of the stainless steel sheet, the spring 606 will release its own tension state in real time and drive the support plate 601 to push up the side of the stainless steel sheet. In addition, during the process of the support plate 601 pushing up the side of the stainless steel sheet, the support plate 601 can be smoothly turned to the top surface by rotating the hinge seat 602 around the rotating shaft 603, so that the support plate 601 is in real time attached to the bottom surface of the side of the stainless steel sheet.The support plate 601 can be attached to and supported on the bottom surface of the stainless steel plate in real time by rising and flipping at the same time, and a certain force can be applied to the upward flipping of the stainless steel plate from the lateral position, so that the stainless steel plate can be guided to smoothly realize the process of flipping upward at both sides during the bending process, thereby preventing the stainless steel plate and the edge position of the top of the bending groove 501 from generating creases. Specifically, in the process of bending the stainless steel plate by the convex mold body 4 as the push rod 106 descends, the descent of the convex mold body 4 is accurately positioned and guided by the guide stud 302 in the process of vertically sliding along the guide hole 305, and at the same time, the limiting nut 303 on the periphery of the guide stud 302 is released from the top surface of the U-shaped frame 104, so that the lowest position of the descent of the convex mold body 4 can be safely limited, and then the descent of the convex mold body 4 can be prevented from being too low and damaging the bending position of the stainless steel plate by limiting the descent of the convex mold body 4 to the lowest position, which is beneficial to further improve the product quality of the stainless steel plate after bending. At the same time, because the limiting nut 303 can be turned, The limit nut 303 is adjusted in the vertical position and height, and then the limit nut 303 can be adjusted to a suitable safety limit position according to the thickness of the stainless steel plate to be bent, thereby improving the adaptability and flexibility during use. Specifically, in operation, when the position and height of the limit nut 303 are adaptively adjusted, when the stainless steel plate is not placed on the top surface of the die body 5, the hydraulic cylinder body 101 drives the punch body 4 to descend to the lower part through the push rod 106 to fully adapt to the bending groove 501 and then remain motionless, and then Then screw the limiting nuts 303 down until they touch the top surface of the U-shaped frame 104, and then screw the limiting nuts 303 up until the distance between the bottom surface of the limiting nuts 303 and the top surface of the U-shaped frame 104 is equal to the thickness of the stainless steel sheet to be bent. The distance between the bottom surface of the limiting nuts 303 and the top surface of the U-shaped frame 104 can be compared and adjusted by placing the stainless steel sheet to be bent horizontally, thus completing the adaptive adjustment of the position height of the limiting nuts 303 and achieving the adjustment of the limiting nuts 303 to a suitable safety limit position.
