[0002] Hardware fittings refer to machine parts or components made of hardware, as well as some small hardware products. They can be used alone or as assisting tools, such as hardware tools, hardware components, daily hardware, building hardware, and security products, etc. Hardware parts need to be made into different shapes to meet the market demand. Bending is an important process in the processing of hardware pipes and plates, and a numerical control bending machine bends metal plates in a cold state into workpieces with various geometric cross-sectional shapes by using the equipped molds;

[0003] For example, a numerical control bending machine for processing hardware parts with the patent publication number CN202321541082.1, which relates to the technical field of hardware part processing, includes a processing table. A fixing structure is fixedly installed on the top of the processing table, and a bending device is fixedly installed on the top of the processing table. The bending device is located above the fixing structure;

[0004] Since the clamping and restraining effect of the above numerical control bending machine on hardware parts is limited, and it is inconvenient to freely adjust the clamping operation of the intermediate hardware parts. During the bending process of hardware parts, situations such as paint peeling may occur, and it is necessary to regularly clean the dropped debris and impurities, which brings certain adverse effects to the actual use. Therefore, improvements are needed. Content of the Utility Model

The utility model can clamp and bend hardware parts inside the bending machine, and perform multi-point and multi-direction clamping and positioning on the main rod of the hardware parts, reducing the situation of loosening and slipping during the clamping of hardware parts, and increasing the collection work of the dropped debris of hardware parts at the collection place, so as to solve the problems raised in the above background technique.

[0006] To achieve the above purpose, the utility model provides the following technical solutions:

A bending machine case is fixedly installed on the top of the numerical control base platform. A pushing groove is opened on the left side of the bending machine case. An electric cylinder is fixedly installed on the left side near the inner wall of the bending machine case. The output end of the electric cylinder is fixedly connected with a clamping plate.

The output end of the hydraulic cylinder is fixedly connected with a moving plate. The upper surface of the moving plate is slidably connected with the upper surface of the inner wall of the bending machine case. A driving motor is fixedly installed at the bottom of the moving plate. The output end of the driving motor is fixedly connected with a rotating abutting plate. A locking component is connected to the surface of the rotating abutting plate. A wear-resistant bending abutting plate is connected to the surface of the locking component. An electric push rod is fixedly installed inside the numerical control base platform near its left side. The output end of the electric push rod is clamped with a lower supporting groove plate. A groove is opened inside the numerical control base platform near its right side. A shock absorber is fixedly connected to the bottom of the inner wall of the groove. The top of the shock absorber is fixedly connected with a debris receiving frame with a front door. The debris receiving frame is located directly below the rotating abutting plate.

[0008] Further, a spring telescopic rod is fixedly installed on the surface of the inner wall of the pushing groove, and a guide wheel is fixedly installed at one end of the spring telescopic rod.

[0009] Further, a wear-resistant pad is fixedly connected to the outer surface of the guide wheel, and an anti-corrosion coating is applied to the surface of the wear-resistant pad.

[0010] Further, an anti-slanting sliding plate is fixedly connected to the left side of the clamping plate. An anti-slanting sliding groove is opened on the top of the inner wall of the bending machine case. The inner wall of the anti-slanting sliding groove is slidably connected with the surface of the anti-slanting sliding plate.

[0011] Further, the number of both the electric cylinders and the clamping plates is four, and the four electric cylinders and clamping plates are evenly distributed at the front, back, left, and right of the left half of the bending machine case.

[0012] Further, the locking component includes a locking card plate and a locking card slot. The locking card plate is fixedly connected to the side surface of the wear-resistant bending abutting plate. The locking card slot is opened on the surface of the rotating abutting plate, and the inner wall of the locking card slot is clamped and adapted to the surface of the locking card plate.

[0013] Further, a guide plate is fixedly connected to the side surface of the debris receiving frame. A guide groove is opened on the side surface of the inner wall of the groove. The inner wall of the guide groove is slidably connected with the surface of the guide plate.

[0014] The beneficial effects of the present utility model are:

[0015] In the present utility model, the hardware parts are pushed into the interior through the left pushing groove of the bent chassis. When the hardware parts are slowly pushed into the clamping and bending position of the rotating abutment plate, the operation of the electric cylinder can drive the clamping plate to move. Anti-slant sliding plates and anti-slant sliding grooves are added for the clamping plate, which can ensure the stable movement of the clamping plate in the bent chassis. The front and rear clamping plates approach each other to clamp and hold the hardware parts. The electromagnetic suction plate generates magnetic suction after being energized to perform secondary adsorption and clamping of the hardware parts. Moreover, the left and right groups of clamping plates can simultaneously restrict the front and rear ends of the hardware parts to assist in enhancing the auxiliary positioning effect on the hardware parts. Then, the operation of the electric push rod drives the lower supporting groove plate to abut against the lower part of the hardware parts to provide a supporting effect, ensuring the main anti-loosening clamping effect of the hardware parts during the bending process, and achieving a multi-directional stable clamping and positioning effect of the hardware parts during the bending process;

[0016] In the present utility model, two wear-resistant bending abutment plates on the rotating abutment plate can be used to clamp, abut against, and restrict the hardware parts. Then, by controlling the operation of the hydraulic cylinder, the moving plate is driven to move. The movement of the moving plate can drive the rotating abutment plate to move. The rotating abutment plate can be moved and adjusted to the bending position. The operation of the driving motor can drive the rotating abutment plate to rotate. The wear-resistant bending abutment plate can be used to perform the bending operation on the hardware parts. And during the bending process of the hardware parts, the position of the rotating abutment plate can be adjusted according to the program for rotational bending. The debris falling during the bending process will fall into the debris receiving frame. As the debris in the debris receiving frame accumulates and increases in weight, causing downward pressure, the shock absorber can perform compression and shock absorption. Under the action of the guide plate and the guide groove, the situation of the debris receiving frame being skewed during the movement process is reduced, and the numerical control adjustment bending of the hardware parts and the collection of the falling debris can be realized.

A locking assembly is connected to the surface of the rotating abutting plate 9. A wear-resistant bending abutting plate 10 is connected to the surface of the locking assembly. An electric push rod 11 is fixedly installed inside the numerical control base 1 near its left side. The output end of the electric push rod 11 is clamped with a lower support groove plate 12. A groove is formed inside the numerical control base 1 near its right side. A shock absorber 13 is fixedly connected to the bottom of the inner wall of the groove. The top of the shock absorber 13 is fixedly connected to a debris receiving frame 14 with a front door. The debris receiving frame 14 is located directly below the rotating abutting plate 9.

[0028] Specifically, as Figures 1 - 6 shown, a spring telescopic rod 15 is fixedly installed on the surface of the inner wall of the pushing groove. One end of the spring telescopic rod 15 is fixedly installed with a guide wheel 16. A wear-resistant pad 17 is fixedly connected to the outer surface of the guide wheel 16. An anti-corrosion coating is filled on the surface of the wear-resistant pad 17. The guide wheel 16 at the spring telescopic rod 15 can abut against the moving hardware part, achieving the effect of automatically adapting to abut and guiding the moving hardware part.

[0029] Specifically, as Figures 1 - 6 shown, the number of the electric cylinders 3 and the clamping plates 4 is four each. The four electric cylinders 3 and the clamping plates 4 are evenly distributed at the front, back, left, and right of the left half of the bending machine case 2. The front and rear two clamping plates 4 can be close to each other to clamp and maintain the hardware part, and the left and right two groups of clamping plates 4 can simultaneously restrict the front and rear ends of the hardware part to assist in enhancing the auxiliary positioning effect of the hardware part.

[0030] Furthermore, the locking assembly includes a locking card plate 20 and a locking card slot 21.

[0031] Example 2 Please refer to Figures 1 - 6, the difference between this embodiment and Embodiment 1 lies in that: an anti-slant slide plate 18 is fixedly connected to the left side of the clamping plate 4, and an anti-slant slide groove 19 is formed at the top of the inner wall of the bending machine case 2. The inner wall of the anti-slant slide groove 19 is slidably connected to the surface of the anti-slant slide plate 18.

Under the action of the guiding plate 22 and the guiding groove 23, the situation of skew during the movement of the debris receiving frame 14 is reduced.

[0032] The working principle of the present utility model: When in use, the staff can push the hardware part into the inside thereof through the pushing groove on the left side of the bending machine case 2. According to the bending situation of this batch of hardware parts, the wear-resistant bending abutting plate 10 and the lower supporting groove plate 12 of appropriate specifications can be installed and clamped tightly. When slowly pushing the hardware part into the clamping and bending position of the rotating abutting plate 9, the electric cylinder 3 operates to drive the clamping plate 4 to move. The anti-slant slide plate 18 and the anti-slant slide groove 19 are added for the clamping plate 4, which can ensure the stable movement of the clamping plate 4 in the bending machine case 2. The front and rear two clamping plates 4 approach each other to clamp and maintain the hardware part. The electromagnetic suction plate 5 generates a magnetic suction force after being powered on to perform secondary adsorption and clamping of the hardware part, and the left and right two groups of clamping plates 4 can constrain the front and rear ends of the hardware part simultaneously to assist in enhancing the auxiliary positioning effect on the hardware part. Then the electric push rod 11 operates to drive the lower supporting groove plate 12 to abut against the lower part of the hardware part for supporting effect, ensuring the main anti-loosening clamping effect of the hardware part during the bending process. Under the clamping of the two wear-resistant bending abutting plates 10 on the rotating abutting plate 9, the anti-slip abutting of the bending part of the hardware part can be carried out. Then control the hydraulic cylinder 6 to operate to drive the moving plate 7 to move. The movement of the moving plate 7 can drive the rotating abutting plate 9 to move. The rotating abutting plate 9 can be moved and adjusted to the bending position. The driving motor 8 operates to drive the rotating abutting plate 9 to rotate. The wear-resistant bending abutting plate 10 can be used to perform the bending operation of the hardware part, and during the bending process of the hardware part, the position of the rotating abutting plate 9 can be adjusted according to the program for rotational bending. The debris falling during the bending process will fall into the debris receiving frame 14. As the debris in the debris receiving frame 14 accumulates and increases in weight, causing downward pressure, the shock absorber 13 can perform compressive shock absorption. Under the action of the guiding plate 22 and the guiding groove 23, the situation of skew during the movement of the debris receiving frame 14 is reduced, and the multi-directional stable clamping and positioning effect of the hardware part during the bending process can be realized.
