[0001] This utility model relates to the field of metal processing equipment, and in particular to a punching and bending integrated machine. Background Technology

[0002] A condenser is a component of a refrigeration system, a type of heat exchanger that converts gas or vapor into liquid, rapidly transferring heat from the tubes to the surrounding air. The condenser's operation is exothermic, hence its relatively high temperature.

[0003] Iron sheets are essential components in the condenser manufacturing process. Before being assembled into a condenser, the iron sheets need to be punched and bent. Existing punching and bending equipment operates independently, which not only occupies a large space, but also requires a transfer process after punching / bending, and the iron sheets need to be disassembled and reassembled again, wasting a lot of time and reducing production efficiency. Utility Model Content

[0006] The punching mechanism includes an upper die and a lower die. The upper die and the lower die are aligned and press together to punch the iron sheet. The lower die is fixedly installed on the worktable and has an arc-shaped edge at one of its corners.

[0007] The bending mechanism includes an inclined bending die with a bending groove at the bottom that matches the curved edge. The bending die presses down to make the bending groove match the curved edge to bend the sheet metal.

[0008] Preferably, the punching mechanism further includes a punching hydraulic cylinder, an assembly block, a spring, and a pre-bending block. The punching hydraulic cylinder is vertically assembled, the assembly block is connected to the piston end of the punching hydraulic cylinder, and the upper die is elastically mounted on the assembly block by a spring, so that the upper die and the lower die perform initial pressing and fixing of the sheet metal when they are in contact.

[0009] Preferably, the punching mechanism further includes a first guide component, wherein the first guide component is connected and assembled with the back of the assembly block to enable the assembly block to move up and down stably.

[0010] Preferably, the punching mechanism further includes two straightening components, which are respectively disposed on the back of the lower die and on one side of the arc edge, wherein the straightening components include a straightening cylinder and a push block installed on the piston end of the straightening cylinder.

[0011] Preferably, the upper mold has a straightening block at the front center, a slope at the bottom rear of the straightening block, and the lower mold has a groove at the front end that corresponds to the straightening block.

[0012] Preferably, the bending mechanism further includes a bending hydraulic cylinder and a second guide assembly, wherein the bending hydraulic cylinder is arranged at an angle so that the bending die mounted on its piston end corresponds to the arc plate of the lower die, and the second guide assembly is connected and assembled with the bending die to make the bending die move stably.

[0013] Preferably, the bottom of the material box has a hole that extends through the workbench. A lifting mechanism is provided below the hole, and a sensor that works with the lifting mechanism is provided on the top of the material box so that the lifting mechanism keeps the sheet metal in the material box at the same height so that the handling mechanism can grab it.

[0016] Preferably, the workbench has a discharge hole in front of the lower mold, and an inclined guide plate is provided at the bottom of the discharge hole.

[0017] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0018] 1. This utility model integrates the punching mechanism and the bending mechanism on the same workbench on the same frame. Compared with the traditional two separate devices, it reduces the space occupied by the equipment. During operation, the set-in conveying mechanism grabs the iron sheet stored in the material box and transports it to the punching mechanism. The punching mechanism punches holes in the iron sheet. At the same time, the bending mechanism operates with the punching mechanism as the clamping and fixing base and cooperates with the punching die to bend one end of the iron sheet. During the processing, there is no need to disassemble and move the iron sheet, thereby shortening the time and improving the production efficiency.

[0019] 2. In this utility model, a pre-bending block is provided on the upper die of the punching mechanism. When the upper die and the lower die work together to punch the iron sheet, the pre-bending block moves down with the upper die, so that it contacts the iron sheet and performs preliminary bending treatment on the iron sheet with the arc edge, providing favorable conditions for the subsequent bending mechanism to bend the iron sheet.

[0020] 3. This utility model has sensors and lifting mechanisms installed at the top and bottom of the material box, respectively. The sensors detect the height of the iron sheet. When the height is lower than the set height, the lifting mechanism lifts the iron sheet inside the material box upward, so that the iron sheet is always kept within the range that can be grabbed by the conveying mechanism. This realizes the automatic feeding of the iron sheet, improves the automation level of the equipment, and further improves the work efficiency.

[0021] 4. This utility model adds two straightening components to the punching mechanism and a straightening block to the upper mold. Before punching, the two straightening components and the straightening block push and straighten the iron sheet on the lower mold to avoid positional deviation of the iron sheet and keep the iron sheet in the original set position for punching, thereby improving the punching quality and reducing the generation of defective products.

[0029] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby providing a clearer and more definite definition of the scope of protection of the present invention.

[0030] This utility model provides a punching and bending integrated machine, such as Figure 1-6 As shown, it includes a frame 1, a workbench 2 is provided on the frame 1, a material box 3 and a conveying mechanism 4 are provided at the front end of the top surface of the workbench 2, and a punching mechanism 5 and a bending mechanism 6 are provided at the rear end of the top surface of the workbench 2.

[0031] In this embodiment, the punching mechanism 5 includes a punching hydraulic cylinder 51, an assembly block 52, a spring 53, an upper die 54, a lower die 55, and a pre-bending block 56. The punching hydraulic cylinder 51 is vertically assembled, and the assembly block 52 is connected to the piston end of the punching hydraulic cylinder 51. The upper die 54 is elastically mounted on the assembly block 52 by the spring 53, so that the upper die 54 and the lower die 55 perform initial pressing and fixing of the iron sheet when they are in contact. The upper die 54 continues to descend and cooperates with the lower die 55 to squeeze the iron sheet for punching.

[0032] During punching, the punching hydraulic cylinder 51 drives the assembly block 52 and the upper die 54 to move downward. Under the action of the spring 53, the upper die 54 first comes into elastic contact with the lower die 55, thereby slowly clamping and fixing the iron sheet on the lower die 55 for positioning the iron sheet. As the upper die 54 continues to descend, the spring 53 is compressed, and the top of the upper die 54 abuts against the spring 53, while the bottom abuts against the iron sheet and the upper die 54. Under strong pressure, the upper die 54 cooperates with the lower die 55 to punch the iron sheet.

[0033] Furthermore, the lower die 55 is fixedly installed on the worktable 2, and an arc-shaped edge 552 is provided at one of its corners. When the upper die 54 and the lower die 55 cooperate to punch holes in the iron sheet, the pre-bending block 56 moves down with the upper die 54, so that it contacts the iron sheet and cooperates with the arc-shaped edge 552 to perform preliminary bending treatment on the iron sheet, providing favorable conditions for the subsequent bending mechanism 6 to bend the iron sheet.

[0034] In this embodiment, the bending mechanism 6 includes a bending hydraulic cylinder 61 and a second guide assembly 62. The bending hydraulic cylinder 61 is inclined so that the bending die 63 assembled at its piston end is inclined, so that the bending die 63 corresponds to the arc plate of the lower die 55. The second guide assembly 62 is connected and assembled with the bending die 63 to make the bending die 63 move stably. The bottom of the bending die 63 is provided with a bending groove 631 that matches the arc edge 552. The bending die 63 presses the lower die 55 so that the bending groove 631 cooperates with the arc edge 552 to bend the iron sheet.

[0035] During bending, the upper die 54 and lower die 55 of the punching mechanism 5 remain in the punching state. At this time, the bending hydraulic cylinder 61 drives the bending die 63 to approach the lower die 55. During the movement, the bending die 63 maintains a linear movement by relying on the second guide component 62. When the bending groove 631 of the bending die 63 contacts and is squeezed by the arc plate of the lower die 55, one end of the sheet metal is bent into shape. Since this end has been pre-bent by the pre-bending block 56 during punching, the bending die 63, in conjunction with the lower die 55, can easily bend the sheet metal into shape and improve the bending effect. This prevents the sheet metal from being damaged by impact when it just contacts the bending die 63, thus reducing product quality.

[0036] It can be noted that the first guide component and the second guide component have the same structure, both including a linear guide rail and a slider. The number of sliders can be adaptively set according to the size of the connecting components. In this embodiment, the slider is used to connect with the assembly block 52 and the bending die 63 to keep them moving in a straight line.

[0037] This application integrates the punching mechanism 5 and the bending mechanism 6 onto the workbench 2 on the same frame 1, reducing the space occupied by the equipment compared to the traditional two separate devices. During operation, the conveying mechanism 4 picks up the iron sheet stored in the material box 3 and transports it to the punching mechanism 5, which punches holes in the iron sheet. At the same time, the bending mechanism 6 operates with the punching mechanism 5 as a clamping and fixing base and works with the punching die to bend one end of the iron sheet. During the processing, there is no need to disassemble and move the iron sheet, thereby shortening the time and improving production efficiency.

[0038] In this embodiment, the bottom of the material box 3 is provided with a hole that extends through the workbench 2. A lifting mechanism 7 is provided below the hole, and a sensor 31 that cooperates with the lifting mechanism 7 is provided on the top of the material box 3 so that the lifting mechanism 7 can lift the sheet metal in the material box 3 at the same height so that the handling mechanism 4 can grab it.

[0039] As products are continuously punched and bent, the height of the products inside the material box 3 gradually decreases. At this time, the height of the sheet metal is detected by the sensor 31. When it is lower than the set height (i.e., the height that the conveying mechanism 4 cannot grasp), the lifting mechanism 7 lifts the sheet metal inside the material box 3 upward, so that the sheet metal is always kept within the range that can be grasped by the conveying mechanism 4. This realizes the automatic feeding of the sheet metal, improves the automation level of the equipment, and further improves the work efficiency.

[0040] Furthermore, the punching mechanism 5 also includes a first guide component 57, wherein the first guide component 57 is connected and assembled with the back of the assembly block 52 to make the assembly block 52 move up and down stably.

[0041] Furthermore, the punching mechanism 5 also includes two straightening components 58, which are respectively located on the back of the lower mold 55 and on one side of the arc edge 552. Each straightening component 58 includes a straightening cylinder 581 and a push block 582 installed on the piston end of the straightening cylinder 581. Before punching, the two straightening components 58 push and straighten the iron sheet on the lower mold 55 to avoid positional deviation of the iron sheet and keep the iron sheet in the original set position for punching, thereby improving the quality of punching and reducing the generation of defective products.

[0042] Furthermore, a straightening block 541 is provided in the middle of the front of the upper mold 54, and an inclined surface is provided behind the bottom of the straightening block. The front end of the lower mold 55 is provided with a groove 551 that corresponds to the straightening block 541. Before punching, the upper mold 54 gradually descends, and the straightening block 541 first contacts the front of the iron sheet. Under the action of the inclined surface, the iron sheet is moved to the rear until the straightening block 541 is completely embedded in the groove 551. With the cooperation of the straightening block 541 and the groove 551, the position of the iron sheet is further accurately positioned to ensure the quality of punching.

[0043] In this embodiment, the lifting mechanism 7 includes a lifting cylinder 71 and a bracket 72. The lifting cylinder 71 is vertically mounted, and the bracket 72 is installed on the piston end of the lifting cylinder 71. The top of the bracket 72 passes through the hole in the material box 3 and abuts against the iron sheet, which is used to lift the iron sheet to move upward in the material box 3.

[0044] In this embodiment, the conveying mechanism 4 is arranged horizontally, with its two ends extending to the punching mechanism 5 and the material box 3 respectively. The conveying mechanism 4 includes a horizontal moving module 41, a telescopic cylinder 42 and a suction nozzle 43. The telescopic cylinder 42 is mounted on the free end of the horizontal moving module 41, and the suction nozzle 43 is mounted on the piston end of the telescopic cylinder 42 for sucking up sheet metal.

[0045] In this embodiment, the workbench 2 has a discharge hole 8 in front of the lower mold 55. An inclined guide plate 9 is provided at the bottom of the discharge hole 8. The punched and bent iron sheet is removed from the lower mold 55 by the conveying mechanism 4 and then transferred to the discharge hole 8, where it slides down the inclined angle of the guide plate 9 for discharge.

[0046] Several points should be noted: First, in the description of this application, it should be noted that, unless otherwise specified and limited, the terms "installation", "connection" and "linkage" should be interpreted broadly, and can be mechanical or electrical connection, or internal connection between two components, or direct connection.
