Description

Technical Field

[0001] The utility model relates to the technical field of numerical control hydraulic plate bending machines, and specifically relates to a numerical control hydraulic plate bending machine for producing high-precision vehicle-mounted pedals. Background Technique

[0002] A vehicle-mounted pedal is a footrest installed on a vehicle, mainly used to facilitate the driver and passengers to enter and leave the vehicle, as well as to support the feet and adjust the driving posture during driving. A plate bending machine is a machine that can bend thin plates. Under the pressure of the upper die or the lower die of the plate bending machine, the metal sheet first undergoes elastic deformation and then enters plastic deformation. In the initial stage of plastic bending, the sheet is freely bent. As the upper die or the lower die presses on the sheet, the sheet gradually presses against the inner surface of the V-shaped groove of the lower die. At the same time, the radius of curvature and the bending moment arm also gradually become smaller. Continue to apply pressure until the stroke ends, so that the upper and lower dies and the sheet are in full contact at three points. At this time, a V-shaped bend is completed, which is commonly known as bending. Existing bending equipment generally controls the action of the hydraulic system through a numerical control system, and drives the upper die to act through the hydraulic system to press and fold the metal sheet.

[0003] When feeding, generally, manual pushing is used to control the feeding amount of the sheet, which increases the workload of the staff. And there is no limit structure when pushing the sheet, so the sheet will tilt to a certain extent. In addition, when pressing and folding, in addition to bending at the pressing and folding position, the sheets in some other parts need to be manually assisted to push them to align with the bending angle, which also increases the workload of the staff.

[0004] Therefore, those skilled in the art provide a numerical control hydraulic plate bending machine for producing high-precision vehicle-mounted pedals to solve the problems raised in the above background technique. Content of the Utility Model

[0005] The purpose of the utility model is to provide a numerical control hydraulic plate bending machine for producing high-precision vehicle-mounted pedals to solve the problems raised in the above background technique.

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

[0007] A numerically controlled hydraulic plate folding machine for the production of high-precision vehicle pedals, comprising a box body, a sliding door, a support plate and a V-groove support table. The front end of the box body is fixedly connected with a support plate. A first chute is opened at the front end of the support plate. Two groups of first sliders are slidably connected in the first chute. Connecting blocks are fixedly connected to the front ends of the first sliders. Limiting plates are fixedly connected to one sides of the connecting blocks. A hydraulic press is fixedly installed on the inner wall of the top of the box body. A telescopic shaft is arranged at the lower end of the hydraulic press. The lower end of the telescopic shaft is fixedly connected with a mounting seat. An upper die is inserted into the mounting seat. A V-groove support table is arranged below the upper die. A rectangular groove is opened at the upper end of the V-groove support table. A trapezoidal groove is arranged in front of the rectangular groove. The trapezoidal groove is opened on the V-groove support table. A rotating plate is arranged above the rectangular groove and the trapezoidal groove. The front end of the rotating plate is an inclined side. Connecting shafts are fixedly connected to both left and right sides of the rotating plate. The connecting shafts are rotatably connected to the V-groove support table. A second chute is arranged in front of the V-groove support table. The second chute is opened on the support plate and the box body. A second servo motor is fixedly installed at the front end of the second chute. A second threaded rod is fixedly connected to the power output end of the second servo motor. The second threaded rod is rotatably connected in the second chute.

[0008] As a further scheme of the present invention: A second slider is threadedly connected to the second threaded rod. The second slider is clamped in the second chute. A push plate is fixedly connected to the upper end of the second slider. Two groups of fixing bolts are threadedly connected to the mounting seat. The mounting seat and the upper die can be fixed together through the fixing bolts.

[0009] As a further scheme of the present invention: Slide bars are fixedly connected to both the front and rear sides of the V-groove support table. A groove chamber is opened at the bottom of the box body. The V-groove support table is inserted into the groove chamber. Grooves are opened on both the front and rear sides of the groove chamber. The slide bars are clamped in the grooves.

[0010] As a further scheme of the present invention: A first servo motor is fixedly installed on the left side of the support plate. A bidirectional screw rod is fixedly connected to the power output end of the first servo motor. The bidirectional screw rod is rotatably connected in the first chute. The bidirectional screw rod is threadedly connected to the first slider.

[0011] As a further scheme of the present invention: The front end of the box body is electrically connected to a controller. A base is fixedly connected to the lower end of the box body. Locking universal wheels are bolted to the four corners of the lower end of the base.

[0012] As a further scheme of the present invention: A push-pull groove is opened on the upper surface of the left end of the base. A push-pull groove is also opened on the upper left side of the box body. A sliding door is slidably connected in the push-pull groove. A glass window is arranged on the sliding door.

[0013] Compared with the prior art, the beneficial effects of the present invention are:

[0014] 1. When feeding the material, place the sheet metal behind the push plate, and then start the second servo motor. The push plate can push the sheet metal to move onto the V-groove support table. In this way, manual pushing is not required, reducing the workload of the staff. In addition, the limit plate can adjust the left and right positions to limit the sheet metal and prevent it from tilting.

[0015] 2. When folding, start the hydraulic press. The upper die can press the sheet metal into the V-shaped groove to achieve folding. At the same time, one end of the rotating plate belt with an inclined side will rotate into the trapezoidal groove as the folding progresses. Then the rotating plate will fit against the surface of the sheet metal and push the sheet metal above the trapezoidal groove, assisting it to rotate and align with the inclined side at the rear of the V-shaped groove. In this way, manual assistance for the rotation of the remaining parts of the sheet metal is not required, reducing the workload of the staff.

[0016] 3. Pull the V-groove support table out of the groove chamber to replace V-groove support tables of different models. After removing the fixing bolts, the upper die can be pulled out of the mounting seat to replace upper dies of different models. In this way, mold replacement is relatively convenient and can adapt to the production of products of different models. Description of the Drawings

At the same time, the end with the hypotenuse of the rotating plate 10 will rotate into the trapezoidal groove 12 along with the pressing and folding. After that, the rotating plate 10 will fit with the surface of the sheet material and push the sheet material above the trapezoidal groove 12, thereby assisting it to rotate to align with the rear hypotenuse of the V-shaped groove.

[0027] Embodiment 2

[0028] Refer to Figures 1-6, this embodiment is based on the previous embodiment. The difference from the previous embodiment is that there are two groups of fixing bolts connected by threads on the mounting base 29.
