Description

Technical Field

[0001] This utility model relates to the field of bending device technology, and in particular to a bending device for the production of stainless steel hinges. Background Technology

[0002] Bending is a crucial step in the production of stainless steel hinges. However, traditional bending machines have several shortcomings when bending stainless steel hinges.

[0003] Firstly, existing bending machines often require multiple steps, such as a first bend, a second bend, and a third bend, to bend stainless steel sheets. However, these steps are not sequential. After each bend, complex adjustments to the equipment or the sheet are necessary, making the entire production process cumbersome and significantly reducing efficiency. For example, after the first bend, extra time and effort are needed to prepare for the second bend. The lack of smooth transitions between steps extends the production cycle.

[0004] Secondly, traditional bending machines heavily rely on manual adjustments by workers during the bending process. From feeding, positioning, and pushing the sheet material to the connection between each bending step, manual operation is required. This not only increases the labor intensity for workers but also, due to the instability of manual operation, is prone to errors, affecting product quality.

[0005] In addition, due to the large amount of manual labor and cumbersome operating procedures required, the production cost of traditional bending machines is relatively high, including both labor costs and indirect costs caused by low production efficiency. Utility Model Content

[0006] To address the shortcomings of existing technologies, this utility model provides a bending device for the production of stainless steel hinges, which has the advantages of automated production and continuous bending operations, thus solving some of the problems mentioned in the background technology.

[0007] This utility model provides the following technical solution: a bending device for producing stainless steel hinges, including a workbench, a bending table fixedly installed near the middle of the upper end of the workbench, a slit provided near the right side of the upper end of the bending table, a rounded corner plate provided at the front end of the upper end of the bending table corresponding to the slit, a turntable rotatably installed near the right side of the upper end of the workbench, a clamping member fixedly connected near the front side of the left end of the turntable, a clamping groove provided at the middle of the rear end of the clamping member, the internal gap of the clamping groove being larger than the internal gap of the slit, an adjusting plate slidably installed through and at the rear end of the bending table corresponding to the slit, and an electric push rod II fixedly installed near the rear side of the upper end of the workbench, the front output end of the electric push rod II being fixedly connected to the adjusting plate.

[0008] Furthermore, a feeding cylinder is fixedly installed on the upper end of the bending table near the left side. Both ends of the feeding cylinder have discharge ports on their lower sides. A pusher plate is slidably installed inside the discharge port. An electric push rod is fixedly installed on the upper end of the worktable near the left side. The right output end of the electric push rod is fixedly connected to the pusher plate. By loading stainless steel sheets into the feeding cylinder, automatic feeding and unloading operations can be realized through this device. The structure is simple and practical.

[0009] Furthermore, the right end of the feeding cylinder is fixedly connected to guide plates near the lower sides of both the front and rear ends. The spacing between the guide plates is equal to the width of the discharge port, which ensures the stability of the stainless steel sheet during feeding and prevents it from shifting.

[0010] Furthermore, a reduction motor is fixedly installed on the upper right side of the workbench. The left output end of the reduction motor is fixedly connected to the axis of the turntable. A through groove is provided at the upper end of the workbench at the corresponding turntable. The lower end of the turntable passes through the interior of the through groove. The design of the through groove can avoid affecting the normal rotation of the turntable.

[0011] Furthermore, a feeding chute is provided at the upper end of the workbench on the right side of the bending table. A collection box is placed inside the workbench on the lower side of the feeding chute. That is, the bent stainless steel sheet will be directly pushed out through the feeding chute and transferred into the collection box in the next group of pushes. The structure is simple and reasonable, which not only achieves a high degree of automation, but also reduces the cost of use.

[0012] Furthermore, the upper end of the bending table is provided with a groove at the corresponding gap. The groove is adapted to the clamping component, that is, the clamping component stops when it reaches the groove under the drive of the turntable, which ensures the rationality of the structural design, bends to a larger angle, and facilitates subsequent processing.

[0013] The advantages of this utility model are as follows:

[0014] 1. The bending device for stainless steel hinge production of this utility model realizes automated feeding operation and clamping function during bending process, eliminating the need for manual adjustment by workers, greatly improving processing efficiency, effectively freeing up labor, reducing labor costs, and making the entire production process smoother and more efficient.

[0015] 2. During the bending process, this device achieves continuous bending of stainless steel sheets through the coordinated action of the turntable and clamping components. This design not only simplifies the tedious process of manually adjusting the sheet position multiple times required by traditional bending machines, but also improves bending efficiency. By precisely controlling the angle and speed of the turntable rotation and adjusting the position of the stainless steel sheet, the deformation process can be better controlled, avoiding cracking or other defects caused by excessive deformation of the stainless steel sheet, ensuring product quality, and improving the product qualification rate. At the same time, the device has a simple structure and reasonable design, effectively reducing production costs. Attached Figure Description

Detailed Implementation

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figures 1-3A bending device for producing stainless steel hinges includes a workbench 1. A bending table 2 is fixedly installed on the upper end of the workbench 1 near the middle. A slit 3 is provided on the upper end of the bending table 2 near the right side. A rounded corner plate 4 is provided on the upper end of the bending table 2 at the front end corresponding to the slit 3. A turntable 10 is rotatably installed on the upper end of the workbench 1 near the right side. A clamping member 11 is fixedly connected to the left end of the turntable 10 near the front side. A clamping groove 12 is provided at the middle of the rear end of the clamping member 11. The internal gap of the clamping groove 12 is larger than the internal gap of the slit 3. An adjusting plate 15 is slidably installed through the rear end of the bending table 2 at the slit 3. An adjusting plate 15 is fixedly installed on the upper end of the workbench 1 near the rear side. There is an electric push rod 16, the front output end of which is fixedly connected to the adjusting plate 15. During the process of pushing the stainless steel sheet into the gap 3, the front end of the stainless steel sheet simultaneously engages with the clamping groove 12 within the clamping member 11. It is worth noting that the area of ​​the stainless steel sheet within the clamping groove 12 is larger than the area within the gap 3. Therefore, when the reduction motor 13 is turned on, causing its output end to drive the turntable 10 to rotate, the rotation of the turntable 10 can drive the clamping member 11 to rotate. Meanwhile, the rear end of the stainless steel sheet is restricted by the gap 3. Simultaneously, under the shaping effect of the rounded corner plate 4, the rotation of the clamping member 11 can drive the stainless steel sheet to be bent, i.e., the stainless steel... The first bending operation of the sheet metal involves further processing. When the turntable 10 rotates the clamping member 11 to the upper middle position, it stops. Since the internal clearance of the clamping groove 12 has a certain margin relative to the stainless steel sheet, opening the electric push rod 16 allows its output end to drive the adjusting plate 15 forward. This, in turn, pushes the stainless steel sheet forward a certain distance via the adjusting plate 15, and then, driven by the reduction motor 13, performs the second bending operation. By adjusting the angle, the deformation process can be better controlled, preventing the stainless steel sheet from cracking or developing other defects due to excessive deformation. Simultaneously, it allows the stainless steel sheet sufficient space to proceed... The final edge rounding process, the third step in the stainless steel sheet bending operation, is performed. Compared to general bending equipment, this device automates the feeding and clamping processes during bending, eliminating the need for manual adjustments and significantly improving processing efficiency. It also frees up labor, boasts a simple and rational design, and effectively reduces production costs while improving product quality. Finally, by opening the electric push rod 8 to push the pusher plate 7 into the gap 3, the bent stainless steel sheet is directly pushed out and falls into the collection box 18 through the discharge chute 17, ensuring the integrity of this technical solution and enhancing automation.

[0022] Please see Figures 1-2A feeding cylinder 5 is fixedly installed on the upper end of the bending table 2 near the left side. Both ends of the feeding cylinder 5 are provided with discharge ports 6 on the lower side. A pusher plate 7 is slidably installed inside the discharge port 6. An electric push rod 8 is fixedly installed on the upper end of the worktable 1 near the left side. The output end of the electric push rod 8 is fixedly connected to the pusher plate 7. Guide plates 9 are fixedly connected on the lower side of the right end of the feeding cylinder 5 near the front and rear ends. The distance between the guide plates 9 is equal to the width of the discharge port 6. First, the sheet material used to make stainless steel hinges is stacked and placed into the feeding cylinder 5. Opening the electric push rod 8 can push the pusher plate 7 to the right, so that the stainless steel sheet material at the lower end is pushed out through the discharge port 6 by the pusher plate 7 and moves to the middle position in the gap 3 under the limiting action of the guide plate 9.

[0023] Please see Figure 1 A geared motor 13 is fixedly installed on the upper right side of the workbench 1. The left output end of the geared motor 13 is fixedly connected to the shaft of the turntable 10. The geared motor 13 can provide sufficient torque to drive the turntable 10 to perform bending operations. A through groove 14 is provided on the upper end of the workbench 1 at the corresponding position of the turntable 10. The lower end of the turntable 10 passes through the interior of the through groove 14. A material feeding groove 17 is provided on the right side of the bending table 2 on the upper end of the workbench 1. A collection box 18 is placed inside the workbench 1 at the lower side of the material feeding groove 17. A groove 19 is provided on the upper end of the bending table 2 at the corresponding gap 3. The groove 19 is adapted to the clamping part 11 to ensure the rationality of the structural design.

[0024] Working principle: In use, the sheet material for making stainless steel hinges is first stacked into the feeding cylinder 5. Turning on the electric push rod 8 causes its output end to push the pusher plate 7 to the right, thus pushing the lower stainless steel sheet through the discharge port 6. Under the limiting action of the guide plate 9, the sheet material moves to the middle position within the gap 3 and stops. During this process, the front end of the stainless steel sheet simultaneously engages with the clamping groove 12 in the clamping member 11. When the reduction motor 13 is turned on, its output end drives the turntable 10 to rotate. The rotation of the turntable 10 drives the clamping member 11 to rotate, and the rotation of the clamping member 11... The stainless steel sheet is bent. Further, when the turntable 10 drives the clamping part 11 to rotate to the upper middle position, it stops. By opening the electric push rod 16, its output end can drive the adjusting plate 15 to push forward. Thus, the stainless steel sheet is moved forward a certain distance by the adjusting plate 15. Then, under the drive of the reduction motor 13, the second bending operation is performed. Finally, when the electric push rod 8 drives the pusher plate 7 to push the next stainless steel sheet into the gap 3, the bent stainless steel sheet can be pushed out directly and fall into the collection box 18 through the feeding chute 17.
