Description

Technical Field

[0001] This utility model relates to the field of punch press protection technology, and in particular to a protection mechanism for a punch press. Background Technology

[0002] A punch press is a stamping press. Stamping production is mainly for sheet metal. Using dies, it can produce blanking, punching, forming, deep drawing, trimming, fine blanking, shaping, riveting, and extruded parts, etc., and is widely used in various fields. When a punch press is running at high speed, small scrap materials and dust generated in the die area fly everywhere, which can easily cause personal injury to employees and damage the dies and products due to dust accumulation, causing unnecessary losses to the factory.

[0003] Chinese utility model patent CN208895064U discloses a safety protection device for a punch press, including an open rectangular frame. First baffle assemblies are respectively arranged on the upper and lower sides of the rectangular frame, and the baffle assemblies are detachably connected to the rectangular frame. Second and third baffle assemblies are respectively arranged on the upper and lower front of the rectangular frame. The second baffle assembly is fixed to the rectangular frame, and the two sides of the third baffle assembly are connected to the rectangular frame via slide rails. The third baffle assembly is connected to a lifting structure, allowing it to move up and down along the rectangular frame via the lifting structure. This application protects employee safety and meets the requirements of cleanroom production, satisfying the requirements of safe, intelligent, and high-precision products.

[0004] Regarding the aforementioned technologies, the inventors believe the following drawbacks exist: The device uses a rectangular frame to block dust and other impurities, and this frame is secured with multiple bolts. When workers need to clean or maintain the punch press, they must disassemble the rectangular frame. This requires simultaneously lifting the frame and removing multiple bolts, making the operation complex and resulting in a poor user experience. Utility Model Content

[0005] To solve the above problems, this utility model provides a protective mechanism for a punch press.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a protective mechanism on a punch press, including a rotating block installed on the side wall of the punch press body and a rectangular frame rotatably mounted on the rotating block, a connecting plate fixed on the side wall of the rectangular frame, a fixing rod installed on the side wall of the connecting plate, and a limiting component for connecting the fixing rod and the connecting plate to each other on the connecting plate.

[0007] By adopting the above technical solution, when workers need to protect employees using the rectangular frame, they must first fix the rotating block and the fixed rod to the two opposite side walls of the punch press, and rotatably connect one end of the rectangular frame to the rotating block to initially stabilize the rectangular frame. Then, workers simply rotate the rectangular frame to gradually bring the other end closer to the fixed rod, causing the limiting component to automatically open and limit the fixed rod, thus stabilizing both ends of the rectangular frame. Furthermore, when workers need to perform operations such as cleaning the punch press, they need to separate the rectangular frame from the fixed rod. At this time, workers only need to activate the drive device to separate the sliding plate from the fixed rod. Then, workers only need to pull the rectangular frame to separate it from the fixed rod.

[0008] Furthermore, a sliding groove is provided on the side wall of the connecting plate, and the limiting component includes a sliding plate slidably disposed in the sliding groove, a compression spring fixed at one end to the side wall of the sliding plate, and a driving device disposed on the connecting plate for driving the sliding plate. The other end of the compression spring is fixed to the inner wall of the sliding groove away from the fixed rod, and a limiting groove is provided on the side wall of the fixed rod near the sliding plate.

[0009] Furthermore, the sliding plate has a first inclined surface on the side wall away from the compression spring to reduce the difficulty for workers to connect the fixing rod and the connecting plate.

[0010] By adopting the above technical solution, when the worker needs to connect the rectangular frame and the fixed rod, the worker needs to rotate the rectangular frame, which moves the rectangular frame closer to the fixed rod. This causes the connecting plate to rotate with the rectangular frame and press against the first inclined surface. At this point, the worker only needs to continue rotating the rectangular frame to allow the sliding plate to move completely into the sliding groove under the action of the connecting plate. Subsequently, when the sliding groove and the limiting groove are aligned, the sliding plate connects with the limiting groove under the action of the compression spring, thereby blocking the rectangular frame and connecting the rectangular frame and the fixed rod.

[0011] Furthermore, a drive groove is provided on the side wall of the connecting plate, and the drive device includes a drive rod slidably disposed in the drive groove and a connecting rope with one end fixed to the side wall of the sliding plate near the compression spring. The other end of the connecting rope extends into the drive groove and is fixed to the side wall of the drive rod.

[0012] By adopting the above technical solution, when the operator needs to separate the rectangular frame from the fixed rod, the operator only needs to slide the drive rod, which will cause one end of the connecting rope to move with the drive rod. This, in turn, causes the sliding plate to move away from the limiting groove under the action of the drive rod and the connecting rope, thus separating the sliding plate from the limiting groove. Furthermore, the operator only needs to pull the rectangular frame to separate the sliding plate from the fixed rod, thereby reducing the difficulty of operation.

[0013] Furthermore, a stabilizing spring is fixed on the side wall of the drive rod away from the connecting rope, and the other end of the stabilizing spring is fixed on the inner wall of the drive groove away from the sliding groove.

[0014] By adopting the above technical solution, when the drive rod is not subjected to external force, it remains stable under the action of the stabilizing spring, thereby improving the user experience for staff.

[0015] Furthermore, baffles are fixed on the two opposite side walls of the drive rod, and the ends of the two baffles that are far apart from each other are slidably connected to the two inner walls of the drive groove.

[0016] By adopting the above technical solution, the baffle reduces the probability of impurities entering the drive tank, thereby improving the user experience for staff.

[0017] Furthermore, a threaded groove is formed on the inner top wall of the sliding groove, and a threaded rod is threadedly connected in the threaded groove. A mounting groove is formed on the upper surface of the sliding plate, and a second inclined surface is formed on the edge of the mounting groove where the inner wall of the mounting groove intersects with the upper surface of the sliding plate.

[0018] Furthermore, a handle is installed at the upper end of the threaded rod to reduce the difficulty for workers to turn the threaded rod.

[0019] By adopting the above technical solution, after the sliding plate and the limiting groove are connected to each other, the operator only needs to rotate the threaded rod to make the threaded rod move downward and press against the second inclined surface, so that the sliding plate continues to move closer to the fixed rod, thereby improving the tightness of the connection between the sliding plate and the fixed rod.

[0020] In summary, this utility model has the following beneficial effects:

[0021] 1. In this application, when workers need to protect employees using a rectangular frame, they must first fix the rotating block and the fixed rod to the two opposite side walls of the punch press, and rotatably connect one end of the rectangular frame to the rotating block to initially stabilize the rectangular frame. Then, workers simply rotate the rectangular frame to gradually bring the other end closer to the fixed rod, causing the limiting component to automatically open and limit the fixed rod, thus stabilizing both ends of the rectangular frame. Furthermore, when workers need to perform operations such as cleaning the punch press, they need to separate the rectangular frame from the fixed rod. At this time, workers only need to activate the drive device to separate the sliding plate from the fixed rod. Then, workers only need to pull the rectangular frame to separate it from the fixed rod.

[0022] 2. In this application, when the operator needs to connect the rectangular frame to the fixed rod, the operator needs to rotate the rectangular frame, which moves the rectangular frame closer to the fixed rod, causing the connecting plate to rotate with the rectangular frame and press against the first inclined surface. At this time, the operator only needs to continue rotating the rectangular frame to allow the sliding plate to move completely into the sliding groove under the action of the connecting plate. Subsequently, when the sliding groove and the limiting groove are aligned, the sliding plate connects with the limiting groove under the action of the compression spring, thereby blocking the rectangular frame and connecting the rectangular frame to the fixed rod.

[0023] 3. In this application, when the operator needs to separate the rectangular frame from the fixed rod, the operator only needs to slide the drive rod, which will cause one end of the connecting rope to move with the drive rod. This, in turn, causes the sliding plate to move away from the limiting groove under the action of the drive rod and the connecting rope, thereby separating the sliding plate from the limiting groove. Furthermore, the operator only needs to pull the rectangular frame to separate the sliding plate from the fixed rod, thus reducing the difficulty of operation for the operator.

[0029] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0030] like Figure 1-4 As shown in the illustration, this application discloses a protective mechanism for a punch press, including a rotating block 1, a rectangular frame 11, a connecting plate 2, a fixing rod 21, a limiting component 3, a stabilizing spring 51, a baffle 6, a threaded rod 7, and a handle 9. The rotating block 1 is mounted on the side wall of the punch press body, and the rectangular frame 11 is rotatably mounted on the rotating block 1. The connecting plate 2 is a rectangular plate structure and is fixed to the side wall of the rectangular frame 11. The fixing rod 21 is a rectangular plate structure and is mounted on the side wall of the connecting plate 2.

[0031] A sliding groove 22 is provided on the side wall of the connecting plate 2. A limiting component 3 is provided on the connecting plate 2 to connect the fixing rod 21 to the connecting plate 2. The limiting component 3 includes a sliding plate 31, a compression spring 32, and a driving device 4. The sliding plate 31 is a rectangular plate structure and is slidably disposed in the sliding groove 22. One end of the compression spring 32 is fixed to the side wall of the sliding plate 31, and the other end of the compression spring 32 is fixed to the inner wall of the sliding groove 22 away from the fixing rod 21. A limiting groove 33 is provided on the side wall of the fixing rod 21 near the sliding plate 31, and a first inclined surface 5 is provided on the side wall of the sliding plate 31 away from the compression spring 32 to reduce the difficulty for workers to connect the fixing rod 21 and the connecting plate 2.

[0032] When the operator needs to connect the rectangular frame 11 to the fixed rod 21, the operator rotates the rectangular frame 11, causing it to move closer to the fixed rod 21. This causes the connecting plate 2 to rotate with the rectangular frame 11 and press against the first inclined surface 5. At this point, the operator continues to rotate the rectangular frame 11, allowing the sliding plate 31 to move completely into the sliding groove 22 under the action of the connecting plate 2. Subsequently, when the sliding groove 22 aligns with the limiting groove 33, the sliding plate 31 connects with the limiting groove 33 under the action of the compression spring 32, thus blocking the rectangular frame 11 and connecting the rectangular frame 11 to the fixed rod 21.

[0033] A drive groove 34 is provided on the side wall of the connecting plate 2. A drive device 4 is disposed on the connecting plate 2 and is used to drive the sliding plate 31. The drive device 4 includes a drive rod 41 and a connecting rope 42. The drive rod 41 is a rectangular rod structure and is slidably disposed in the drive groove 34. One end of the connecting rope 42 is fixed to the side wall of the sliding plate 31 near the compression spring 32, and the other end of the connecting rope 42 extends into the drive groove 34 and is fixed to the side wall of the drive rod 41.

[0034] When the operator needs to separate the rectangular frame 11 from the fixed rod 21, the operator only needs to slide the drive rod 41, which will cause one end of the connecting rope 42 to move with the drive rod 41. This, in turn, causes the sliding plate 31 to move away from the limiting groove 33 under the action of the drive rod 41 and the connecting rope 42, thus separating the sliding plate 31 from the limiting groove 33. Furthermore, the operator only needs to pull the rectangular frame 11 to separate the sliding plate 31 from the fixed rod 21, thereby reducing the difficulty of operation.

[0035] One end of the stabilizing spring 51 is fixed to the side wall of the drive rod 41 away from the connecting rope 42, and the other end of the stabilizing spring 51 is fixed to the inner wall of the drive groove 34 away from the sliding groove 22. When the drive rod 41 is not subjected to external force, the drive rod 41 remains stable under the action of the stabilizing spring 51, thereby improving the user experience for the operator.

[0036] The baffle 6 is a rectangular plate structure, fixed to two opposite side walls of the drive rod 41, with the ends of the two baffles 6 slidably connected to the two inner walls of the drive groove 34 respectively. The baffle 6 reduces the probability of impurities entering the drive groove 34, thereby improving the user experience for operators.

[0037] A threaded groove 61 is formed on the inner top wall of the sliding groove 22. The threaded rod 7 is threaded into the threaded groove 61. A mounting groove 71 is formed on the upper surface of the sliding plate 31. A second inclined surface 8 is formed on the edge of the mounting groove 71 near the inner wall of the limiting groove 33 where it intersects with the upper surface of the sliding plate 31. A handle 9 is installed on the upper end of the threaded rod 7 to reduce the difficulty for the operator to rotate the threaded rod 7.

[0038] After the sliding plate 31 and the limiting groove 33 are connected to each other, the operator only needs to rotate the threaded rod 7 to make the threaded rod 7 move downward and press against the second inclined surface 8, so that the sliding plate 31 continues to move closer to the fixed rod 21, thereby improving the tightness of the connection between the sliding plate 31 and the fixed rod 21.

[0039] The operating principle of the protective mechanism on a punch press in this embodiment is as follows: When a worker needs to protect an employee using the rectangular frame 11, the worker must first fix the rotating block 1 and the fixed rod 21 to the two opposite side walls of the punch press, and rotatably connect one end of the rectangular frame 11 to the rotating block 1, thus initially stabilizing the rectangular frame 11. Subsequently, the worker only needs to rotate the rectangular frame 11, causing the other end of the rectangular frame 11 to gradually approach the fixed rod 21, thereby automatically opening the limiting component 3 and limiting the fixed rod 21, thus stabilizing both ends of the rectangular frame 11. Furthermore, when the worker needs to perform operations such as cleaning the punch press, the worker needs to separate the rectangular frame 11 from the fixed rod 21. At this time, the worker only needs to activate the drive device 4 to separate the sliding plate 31 from the fixed rod 21. Then, the worker only needs to pull the rectangular frame 11 to separate the rectangular frame 11 from the fixed rod 21.

[0040] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
