Description

Technical Field

[0001] This utility model relates to the field of stamping device technology, and in particular to a sheet metal stamping device with auxiliary loading and unloading functions. Background Technology

[0002] In the processing of metal parts, bending the metal parts by punching is a common method of forming them. The metal part is positioned on the lower die fixture of the punching machine's worktable, the upper die is driven to move downward, and the die applies pressure to the sheet metal to deform it, thus completing the bending action.

[0003] For smaller sheet metal parts, the bending action can be smoothly completed by positioning them on the lower die fixture through automated or manual feeding. However, for longer metal sheets, such as those 1 meter or more in length, bending a certain point at one end of the sheet presents several challenges. First, due to the length of the sheet, it is necessary to ensure its stable placement; that is, the end of the sheet away from the fixture also needs support to facilitate the downward pressing action of the punch. Second, because the sheet is long, the other side of the bent sheet will be raised significantly. If there is no support when the punch returns to its original position, the sheet will tip over, preventing stable unloading.

[0004] Therefore, there is a need for equipment suitable for stamping and bending of longer sheet materials. Utility Model Content

[0005] The purpose of this utility model is to provide a sheet metal stamping equipment with auxiliary loading and unloading functions. When the support component is in a low position and in a horizontal state, it is convenient to feed long sheet metal. When it is in an inclined state, it can support one side of the long sheet metal after stamping and bending. The inclined mechanism and the lifting mechanism drive the support component to make the sheet metal on the support component stably in a horizontal state, which facilitates the loading and unloading of sheet metal and ensures the stability of the loading and unloading of sheet metal.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is: a sheet metal stamping equipment with auxiliary loading and unloading functions, comprising:

[0007] A punch press, equipped with fixtures for stamping sheet metal.

[0008] A feeding device includes a frame, a lifting mechanism, a tilting mechanism, and a support assembly. The lifting mechanism includes a drive cylinder and a scissor lift bracket, both mounted on the frame. The scissor lift bracket is connected to the output end of the drive cylinder and is driven to move its upper end vertically. The support assembly is located at the upper end of the scissor lift bracket. The tilting mechanism includes a frame and a push cylinder. The frame is mounted on the scissor lift bracket, and the push cylinder is hinged to the frame. The support assembly is hinged to the output end of the push cylinder and is driven to rotate around its connection point with the scissor lift bracket.

[0009] The support component is driven to be flush with the bearing surface of the fixture for feeding sheet metal, or the support component is driven to be inclined to support one end of the sheet metal after it has been bent and raised by the punch press.

[0010] As a further optimization, the support assembly includes a support member and a spinning cylinder. The support member is disposed on the scissor lift bracket and hinged to the output end of the push cylinder. At least one of the spinning cylinders is disposed on the support member.

[0011] As a further optimization, at least one side of the support member is provided with a baffle plate.

[0012] As a further optimization, the support is a roller feeder, which facilitates the movement of the sheet material on it.

[0013] As a further optimization, the scissor lift bracket includes support arms and an intermediate shaft. A pair of support arms are connected by the intermediate shaft located in the middle of the two. The same end of the pair of support arms is respectively hinged to the frame and the support assembly. The other end of the pair of support arms is respectively movably connected to the frame and the support assembly. The output end of the drive cylinder is hinged to the intermediate shaft.

[0014] As a further optimization, the other end of the support arm, which is hinged to the support assembly, is slidably connected to the frame.

[0015] As a further optimization, each of the pair of support arms is provided with a roller away from its respective hinge end.

[0016] As a further optimization, the frame and / or the support assembly are provided with C-shaped plates for guiding and limiting the movement of the rollers, and the movement of the rollers can be limited by the structure of the C-shaped plates.

[0017] As a further optimization, the frame is equipped with supporting rollers to facilitate movement and docking with the punch press.

[0018] As a further optimization, the positioning element on the fixture can position the sheet metal that needs to be stamped and bent.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] 1. When the support component is driven to a low position and is in a horizontal state to connect with the fixture, it facilitates the feeding of long plates. When the support component is driven to an inclined state, it can support one side of the long plate after stamping and bending. The inclined mechanism and the lifting mechanism drive the support component to make the plate on the support component stable in a horizontal state, which facilitates the loading and unloading of the plate and ensures the stability of the loading and unloading of the plate.

[0027] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0028] like Figures 1 to 4As shown, a sheet metal stamping equipment with auxiliary loading and unloading functions includes a punch press 10 and a feeding device 20. The punch press 10 is equipped with a jig 11 for stamping sheet metal 30. The feeding device 20 includes a frame 21, a lifting mechanism 22, a tilting mechanism 23, and a support assembly 24. The lifting mechanism 22 includes a drive cylinder 221 and a scissor bracket 222. The drive cylinder 221 and the scissor bracket 222 are mounted on the frame 21, and the scissor bracket 222 is connected to the output end of the drive cylinder 221 and is driven to move its upper end up and down. The support assembly 24 Component 24 is disposed on the upper end of scissor lift bracket 222. The tilting mechanism 23 includes a frame 230 and a push cylinder 231. The frame 230 is disposed on the scissor lift bracket 222. The push cylinder 231 is hinged to the frame 230. The support component 24 is hinged to the output end of the push cylinder 231 and is driven to rotate around the connection between it and the scissor lift bracket 222. The support component 24 is driven to be flush with the bearing surface of the fixture 11 for feeding the plate 30, or the support component 24 is driven to be tilted to support one end of the plate 30 after it has been bent and raised by the punch press.

[0029] In this invention, the sheet metal 30 that needs to be stamped and bent by the punch press 10 has a relatively long length. When stamping and bending the sheet metal 30 at a corresponding position (such as the end position near one end), the sheet metal 30 can be placed on the support assembly 24. Preferably, the frame 21 is provided with support rollers 200, which can move the feeding device 20 to a position close to the punch press 10. Since the upper end surface of the support assembly 24 can be flush with the upper end surface of the fixture 11, the sheet metal 30 can be translated, so that the position on the sheet metal 30 that needs to be stamped and bent can be easily translated onto the fixture 11; combined with Figure 5 As shown, after the punch press 10 completes the punching and bending of the sheet metal 30, before the punch of the punch press 10 releases the sheet metal 30, the drive cylinder 221 drives the scissor bracket 222 to rise, causing the support assembly 24 to rise accordingly. The push cylinder 231 actuates, pushing one side of the support assembly 24 to rise. That is, only the connection position between the support assembly 24 and the scissor bracket 222 rotates, while the other side of the support assembly 24 disengages from the scissor bracket 222 and moves upward, causing the entire support assembly 24 to tilt. After the above actions, it tilts. The support component 24 can abut against one side of the bent sheet 30 and support the sheet 30. When the punch of the punch press 10 is reset, it can prevent the sheet 30 from tipping over due to lack of external pressure or support, thus ensuring the stability of the sheet 30 when the punch press 10 is reset. With one side of the bent sheet 30 supported by the support component 24, the sheet 30 can fall smoothly onto the feeding device 20 during the reset process of the tilting mechanism 23 and the lifting mechanism 22, until it is in a low position and horizontal with the support component 24.

[0030] In this utility model, when the support component 24 is driven to a low position and is in a horizontal state relative to the fixture 11, it is convenient to feed the longer plate 30 onto the fixture. When the support component 24 is driven to an inclined state, it can support one side of the longer plate 30 after it has been punched and bent by the punch press 10, which can prevent the longer plate 30 from tipping over after being punched and bent. The inclined mechanism 23 and the lifting mechanism 22 drive the support component 24 so that the plate 30 on the support component 24 is in a low position and in a horizontal state, which is convenient for unloading.

[0031] Preferably, the support assembly 24 includes a support member 241 and a spinning cylinder 242. The support member 241 is mounted on the scissor lift bracket 222 and hinged to the output end of the push cylinder 231. That is, one side of the support member 241 is hinged to one side of the scissor lift bracket 222, and its middle part or the other side is hinged to the output end of the push cylinder 231. When the push cylinder 231 moves to push the support member 241, the other side of the support member 241 can rotate around one end of the scissor lift bracket 222, thereby achieving an inclined state for the support member 241 (support assembly 24); at least one A spinning cylinder 242 is disposed on the support member 241. For example, since the plate 30 is relatively long, two spinning cylinders 242 can be disposed. When one side of the stamped and bent plate 30 abuts against the inclined support member 241, the action of the pair of spinning cylinders 242 can firmly press one side of the plate 30 onto the support member 241. During the process of the support member 241 being driven back to the low position and in a horizontal state, the pressed plate 30 will not slide relative to the support member 241, which can ensure the stability of the movement of the plate 30 driven by the support member 241. Preferably, the support member 241 is a roller feeder, which can be a non-powered feeder. The plate 30 is placed on it, and the operator pushes the plate 30 to move it on it, which can facilitate the movement of the plate 30 on it when the support member 241 is in a low position and in a horizontal state.

[0032] In addition, at least one side of the support member 241 is provided with a baffle plate 243, which can ensure the accuracy of the movement of the plate 30 on the support member 241. The plate 30 can be fed horizontally by contacting one side of the baffle plate 243. Preferably, baffle plates 243 are provided on both opposite sides of the support member 241. On the one hand, this can ensure the accuracy of the horizontal feeding of the plate 30. On the other hand, if the support member 241 is a roller feeder, it can prevent the plate 30 from shifting to one side and sliding out of the support member 241 during the movement.

[0033] The specific structure of the scissor lift bracket 222 includes a support arm and an intermediate shaft 2220. A pair of support arms (such as the first support arm 2221 and the second support arm 2222) are connected by the intermediate shaft 2220 located in the middle of the two. The same end of the first support arm 2221 and the second support arm 2222 are respectively hinged to the frame 21 and the support assembly 24. The other ends of the two are respectively movably connected to the frame 21 and the support assembly 24. That is, one end of the first support arm 2221 is hinged to the upper end of the frame 21, the same end of the second support arm 2222 is hinged to the lower end of the support assembly 24, the other end of the first support arm 2221 is movably connected to the lower end of the support assembly 24, and the same end of the second support arm 2222 is movably connected to the upper end of the frame 21. The frame 230 is set on the first support arm 2221, and the output end of the drive cylinder 221 is hinged to the intermediate shaft 2220. When the drive cylinder 221 is activated, it drives the intermediate shaft 2220 to move upward. The movement of the intermediate shaft 2220 causes the movable ends of the first support arm 2221 and the second support arm 2222 to move closer to the intermediate shaft 2220. This reduces the horizontal extension distance of the first support arm 2221 and the second support arm 2222, while increasing the vertical extension distance. Therefore, it can push the support assembly 24 to move upward. Conversely, the drive cylinder 221 drives the intermediate shaft 2220 to move downward, thereby driving the support assembly 24 to move downward.

[0034] Preferably, the other end of the support arm hinged to the support assembly 24 is slidably connected to the frame 21, that is, the movable end of the second support arm 2222 is slidably connected to the frame 21. The two can translate relative to each other but cannot be separated in the vertical direction, which can ensure the stability of the scissor bracket 222. In addition, the other end of the support arm hinged to the frame 21 is slidably connected to the support assembly 24 and can be separated from each other, that is, the movable end of the first support arm 2221 is slidably connected to the support assembly 24 and can be separated from each other. This can achieve that the lower end of the support assembly 24 is slidably connected to one end of the first support arm 2221 only when the drive cylinder 221 is activated, but when the push cylinder 231 is activated, it can push the end of the support assembly 24 away from its hinge end to be separated from the first support arm 2221, thereby realizing the tilting state of the support assembly 24.

[0035] Preferably, the first support arm 2221 and the second support arm 2222 are respectively provided with rollers away from their respective hinge ends. That is, the first support arm 2221 is provided with a first roller 2231 away from its hinge end, and the second support arm 2222 is provided with a second roller 2232 away from its hinge end. Through the rolling abutment action of the first roller 2231 and the second roller 2232, the first support arm 2221 and the second support arm 2222 can be slidably connected relative to the support assembly 24 and the frame 21, respectively.

[0036] The frame 21 and / or support assembly 24 are provided with C-shaped plates 240 for guiding and limiting the movement of the rollers. Preferably, the C-shaped plate on the frame 21 that cooperates with the second roller 2232 on the second support arm 2222 limits the vertical movement of the second roller 2232, so that the second roller 2232 cannot be disengaged vertically. The C-shaped plate on the support assembly 24 that cooperates with the first roller 2231 on the first support arm 2221 limits the vertical movement of the first roller 2231 horizontally, so that the first roller 2231 cannot be misaligned with the support assembly 24, but can be disengaged vertically.

[0037] In addition, the positioning element 111 on the fixture 11 can limit the feeding of the sheet metal 30 to ensure the accuracy of the stamping and bending position.

[0038] The specific embodiments described herein are merely illustrative examples illustrating the spirit of this utility model. Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to substitute them, without departing from the spirit of this utility model or exceeding the scope defined by the appended claims.
