Description

A high-precision hydraulic press for processing automotive hardware parts

Technical Field

The invention relates to the technical field of automobile manufacturing, in particular to a high-precision hydraulic press for processing automobile hardware accessories.

Background technique

A hydraulic press is a machine that uses liquid as the working medium and is made according to Pascal's principle to transfer energy to achieve various processes. A hydraulic press generally consists of three parts: the machine (host), the power system, and the hydraulic control system. Hydraulic presses are classified into valve hydraulic presses, liquid hydraulic presses, and engineering hydraulic presses.

Hydraulic press (also known as oil press) is a machine that uses liquid static pressure to process metal, plastic, rubber, wood, powder and other products. It is often used in pressing and forming processes, such as forging, stamping, cold extrusion, straightening, bending, flanging, sheet metal drawing, powder metallurgy, press fitting, etc.

At present, the processing of traditional automobile hardware accessories requires the workpiece to be stamped. When the hydraulic press completes the stamping work, it will cause a large impact on the frame and the workpiece. The hydraulic press will generate strong vibration and noise, which will damage the hydraulic press and reduce its service life.

Summary of the invention

To achieve the above objectives, the present invention is implemented through the following technical solutions: A high-precision hydraulic press for processing automobile hardware parts, comprising: a frame having a frame body supporting a hydraulic component, and a connecting fastener arranged at the top of the upper surface of the frame and a fixing block at the middle of the bottom;

A liquid filling box, and a clamping member fixedly connected to the outer surface of the liquid filling box;

A hydraulic assembly, which is used for punching and driving hardware accessories and stabilizing and protecting the guide plate, and a shaft rod at the top and a collar at the bottom of the hydraulic assembly;

A pressing platform, which is used for positioning and replacing stamping dies and placing hardware accessories, and a positioning plate arranged in the middle of the bottom of the pressing platform;

A voltage stabilizing component, the voltage stabilizing component having a stamping part for reducing impact force, and a connecting ring arranged in the middle of the upper surface of the voltage stabilizing component;

The liquid filling box is fixedly connected to the top of the frame, and the liquid filling box is fixedly connected to the connecting fastener on the top of the frame by a clamping piece. The hydraulic component is arranged inside the frame, and the hydraulic component is slidably connected to the outer surface of the frame by a shaft rod, and the shaft rod penetrates the frame and extends to its top, and the hydraulic component is fixedly connected to the clamping piece on the outer surface of the liquid filling box by the shaft rod. The pressure stabilizing component is arranged on the lower surface of the hydraulic component, and the pressure stabilizing component is fixedly connected to the collar at the bottom of the hydraulic component by a connecting ring. The pressing platform is arranged at the bottom of the frame, and the pressing platform is fixedly connected to the fixed block at the bottom of the frame by a positioning plate; the automotive hardware accessories are placed above the pressing platform, and the hydraulic component is started so that the piston in the hydraulic component moves downward to contact the workpiece and presses down to stamp the workpiece. During stamping, the pressure stabilizing component first contacts the workpiece and squeezes the workpiece to produce deformation, thereby reducing the impact force during downward movement.

The pressure stabilizing component includes a connecting circular plate, and the hydraulic component is connected to the connecting circular plate when stamping the workpiece. The connecting circular plate is fixedly connected to the ring at the bottom of the hydraulic component through a connecting ring. The lower surface edge of the connecting circular plate is fixedly connected with an arc-shaped pressing frame, which drives the arc-shaped pressing frame connected to the connecting circular plate and the stamping plate to stamp the workpiece. The stamping plate and the workpiece first contact and squeeze, so that the arc-shaped pressing frame is compressed and contracted. There are six arc-shaped pressing frames, which are distributed in a circular shape on the surface of the connecting circular plate, and the lower surface of the arc-shaped pressing frames is fixedly connected with a stamping plate.

Preferably, an inner support member is fixedly connected to the side of the outer surface of the stamping plate, and three inner support members are provided. The three inner support members are distributed in a circular shape on the surface of the stamping plate, and the inner support members are arranged between the gaps of the two arc-shaped pressing frames.

Preferably, the hydraulic assembly includes a main oil cylinder. Under the action of atmospheric pressure, the one-way valve of the filling tank opens so that the upper chamber of the main oil cylinder is filled with oil. The main oil cylinder serves as a main driving force. The main oil cylinder is slidably connected to the surface of the frame through an axle rod. The bottom of the main oil cylinder is fixedly connected to a movable crossbeam. The top circumference of the movable crossbeam is fixedly connected to a column. When the piston in the main oil cylinder moves downward and contacts the workpiece, the oil in the upper chamber pressurizes the main oil cylinder. The main oil cylinder drives the movable crossbeam to slide on the surface of the column. Four columns are provided. The four columns are slidably connected to the surface of the frame. Stabilizing sliding components are fixedly connected to both sides of the outer surface of the movable crossbeam, and the stabilizing sliding components on both sides are rotated and contracted, so that the pressure stabilizing component punches the workpiece placed in the pressing platform.

Preferably, the stabilizing assembly includes side clamps. Since the hydraulic press will vibrate when used for a long time, when the main oil cylinder drives the movable crossbeam to slide, the side clamps on both sides move downward with the movable crossbeam. The side clamps are fixedly connected to the sides of the outer surface of the movable crossbeam. The outer surface of the side clamps is fixedly connected to an extension rod. Since the compression turning rod position is arranged in sections, and one end is connected to the extension rod and the other end is connected to the frame plate, the end connected to the extension rod rotates on the surface of the end connected to the frame plate as the movable crossbeam moves downward. The surface of the extension rod is rotatably connected to the compression turning rod, so that the movable crossbeam is restricted by the stabilizing assemblies on both sides during the downward process, so that the movable crossbeam is more stable when descending, thereby improving the service life of the hydraulic press.

Preferably, the surface of the compression turning rod away from one end of the extension rod is fixedly connected with a frame plate, and a center block is fixedly connected between the opposite surfaces of the compression turning rod, and the center block is arranged between the compression turning rods. The surface of the center block is rotatably connected with a limiting turning rod. Since the center block is fixedly connected to the compression turning rod close to one end of the extension rod, the center block is displaced and rotated as the compression turning rod moves downward, and the limiting turning rod extending from the center block contacts the frame plate. The limiting turning rod is adapted to the frame plate, and the limiting turning rod is limited by the frame plate, and the compression turning rod stops rotating, so that the vibrating movable crossbeam is limited by the compression turning rods on both sides, and the vibration frequency is reduced when it moves downward, so as to improve the stability of the movable hydraulic press.

Preferably, the pressing platform comprises a bottom plate, which is fixedly connected to a fixed block at the bottom of the frame via a positioning plate, a clamping block is fixedly connected to the upper surface of the bottom plate, and outer groove plates are fixedly connected to both sides of the outer surface of the clamping block.

Preferably, the surface of the outer groove plate is rotatably connected with a clamping plate and a rotating clamp through sliding rods. The staff pushes the clamping plate to slide in the outer groove plate and rotates the rotating clamp to change its opening and closing angle. A pressing plate is fixedly connected between the clamping plate and the rotating clamp, thereby clamping and fixing the pressing plate to facilitate replacement of stamping dies used for different workpieces. Then the staff places the workpiece in the positioning groove and drives the pressure stabilizing assembly to stamp the workpiece through the hydraulic assembly. A positioning groove begins to be provided in the middle of the outer surface of the pressing plate.

Preferably, a surface of the clamping block away from one end of the pressing plate is fixedly connected with a connecting rod, an outer surface of the connecting rod is fixedly connected with a connecting plate, and the connecting plate is fixedly connected to the lower surface of the frame plate.

Preferably, the inner support member includes a fitting cross plate. When the stamping plate contacts the workpiece, the arc-shaped press frame is compressed and contracted, and the fitting cross plate arranged on the outside of the stamping plate drives the bent plate and the external plate to rise upward as the arc-shaped press frame contracts. The fitting cross plate is fixedly connected to the outer surface of the stamping plate, and the outer surface of the fitting cross plate is fixedly connected with bent plates on both sides, and the surface of the bent plate is fixedly connected with an external plate, thereby reducing the impact force when the hydraulic press presses downward, reducing the vibration and noise generated by the hydraulic press stamping, reducing the damage to the hydraulic press, and avoiding excessive deformation of the workpiece caused by stamping, which affects the stamping accuracy.

Preferably, an arc plate is fixedly connected to the inner surface of the external connecting plate, a U-shaped connecting plate is fixedly connected to the middle of the arc plate, and a docking rod is fixedly connected to the surface of the U-shaped connecting plate. After the arc pressure frame contracts, the upper connecting circular plate is driven downward by the hydraulic assembly, recessed downward, and stuck between the three docking rods. The docking rod is pushed by the connecting circular plate so that the U-shaped connecting plate drives the arc plate to move outward, thereby supporting the outside of the pressure stabilizing assembly to avoid excessive force on the connecting circular plate and the stamping plate, which makes it impossible to maintain balance during stamping.

The present invention provides a high-precision hydraulic press for processing automobile hardware parts. It has the following beneficial effects:

1. The high-precision hydraulic press for processing automobile hardware accessories, when the stamping plate contacts the workpiece, the arc-shaped press frame is compressed and contracted, and the fitting horizontal plate arranged on the outside of the stamping plate drives the bent plate and the external plate to rise upward as the arc-shaped press frame contracts, thereby reducing the impact force when the hydraulic press presses down, reducing the vibration and noise generated by the hydraulic press stamping, reducing the damage to the hydraulic press, and avoiding deformation of the workpiece caused by excessive stamping, which affects the stamping accuracy.

2. This high-precision hydraulic press for processing automobile hardware accessories, after the arc-shaped pressing frame shrinks, the upper connecting circular plate is driven downward by the hydraulic component, concave downward, and stuck between the three docking rods. The docking rods are pushed by the connecting circular plate so that the U-shaped connecting plate drives the arc plate to move outward, thereby supporting the outside of the pressure-stabilizing assembly to prevent the connecting circular plate and the stamping plate from being overstressed and unable to maintain balance during stamping.

3. This high-precision hydraulic press for processing automotive hardware accessories, through the staff pushing the clamping plate to slide in the outer groove plate, rotating the clamp to change its opening and closing angle, so as to clamp and fix the pressing plate, so as to facilitate the replacement of the stamping dies used for different workpieces, and then the staff places the workpiece in the positioning groove, and uses the hydraulic component to drive the pressure stabilizing component to stamp the workpiece.

4. The high-precision hydraulic press for processing automobile hardware accessories will generate vibrations when used for a long time. When the main oil cylinder drives the movable crossbeam to slide, the side blocks on both sides move downward with the movable crossbeam. Since the compression turning rod position is set in sections, and one end is connected to the extension rod and the other end is connected to the frame plate, the end connected to the extension rod rotates on the surface of the end connected to the frame plate as the movable crossbeam moves downward. As a result, the movable crossbeam is restricted by the stabilizing components on both sides during the downward process, making the movable crossbeam more stable when descending, thereby increasing the service life of the hydraulic press.

5. The high-precision hydraulic press for processing automobile hardware accessories is arranged between the compression and turning rods through the center block. Since the center block is fixedly connected to the compression and turning rod near one end of the extension rod, the center block is displaced and rotated as the compression and turning rod moves downward, and the limiting rotating rod extending from the center block contacts the frame plate. The limiting rotating rod is restricted by the frame plate, and the compression and turning rod stops rotating, so that the vibrating movable crossbeam is limited by the compression and turning rods on both sides, and the vibration frequency is reduced when it moves downward, so as to improve the stability of the movable hydraulic press.

The second embodiment, on the basis of the first embodiment, please refer to Figures 3 to 6, the hydraulic component 3 includes a main oil cylinder 31, the filling tank 1 opens the one-way valve under the action of atmospheric pressure to fill the upper chamber of the main oil cylinder 31 with oil, the main oil cylinder 31 serves as the main driving force, the main oil cylinder 31 is slidably connected to the surface of the frame 2 through the shaft, the bottom of the main oil cylinder 31 is fixedly connected to a movable crossbeam 32, the top circumference of the movable crossbeam 32 is fixedly connected to a column 33, the piston in the main oil cylinder 31 moves downward and contacts the workpiece to pressurize the oil in the upper chamber of the main oil cylinder 31, the main oil cylinder 31 drives the movable crossbeam 32 to slide on the surface of the column 33, four columns 33 are provided, and the four columns 33 are slidably connected to the surface of the frame 2, the outer surface of the movable crossbeam 32 is fixedly connected to the stabilizing sliding components 34 on both sides, and the stabilizing sliding components 34 on both sides are rotated and contracted, so that the pressure stabilizing component 5 punches the workpiece placed in the pressing platform 4.

The stabilizing and sliding component 34 includes side clamping blocks 341. Since the hydraulic press will vibrate when used for a long time, when the main oil cylinder 31 drives the movable beam 32 to slide, the side clamping blocks 341 on both sides move downward with the movable beam 32. The side clamping blocks 341 are fixedly connected to the sides of the outer surface of the movable beam 32. The outer surface of the side clamping blocks 341 is fixedly connected to an extension rod 346. Since the compression and turning rod 343 is arranged in sections, and one end is connected to the extension rod 346 and the other end is connected to the frame plate 342, the end connected to the extension rod 346 rotates on the surface of the end connected to the frame plate 342 as the movable beam 32 moves downward, and the surface of the extension rod 346 is rotatably connected to the compression and turning rod 343, so that the movable beam 32 is restricted by the stabilizing and sliding components 34 on both sides during the downward process, so that the movable beam 32 is more stable when it moves downward, thereby improving the service life of the hydraulic press.

The surface of the compression and turning rod 343 away from the extension rod 346 is fixedly connected to the frame plate 342, and the opposite surfaces of the compression and turning rod 343 are fixedly connected with a center block 344, and the center block 344 is arranged between the compression and turning rods 343. The surface of the center block 344 is rotatably connected to the limiting rotating rod 345. Since the center block 344 is fixedly connected to the compression and turning rod 343 near one end of the extension rod 346, the center block 344 is displaced and rotated as the compression and turning rod 343 moves downward, and the limiting rotating rod 345 extending from the center block 344 contacts the frame plate 342, and the limiting rotating rod 345 is adapted to the frame plate 342.

The valve fills the upper chamber of the main oil cylinder 31 with oil. The main oil cylinder 31 serves as the main driving force. The main oil cylinder 31 is slidably connected to the surface of the frame 2 through an axle rod. The bottom of the main oil cylinder 31 is fixedly connected to a movable crossbeam 32. The top circumference of the movable crossbeam 32 is fixedly connected to a column 33. The piston in the main oil cylinder 31 moves downward and contacts the workpiece to pressurize the main oil cylinder 31 with the oil in the upper chamber. The main oil cylinder 31 drives the movable crossbeam 32 to slide on the surface of the column 33. Four columns 33 are provided. The four columns 33 are slidably connected to the surface of the frame 2. The outer surface of the movable crossbeam 32 is fixedly connected to stabilizing sliding components 34 on both sides, and the stabilizing sliding components 34 on both sides are rotated and contracted, so that the pressure stabilizing component 5 punches the workpiece placed in the pressing platform 4.

The third embodiment, based on the first and second embodiments, please refer to Figures 7 to 9, the pressure stabilizing component 5 includes a connecting circular plate 54, the hydraulic component 3 is connected to the connecting circular plate 54 when stamping the workpiece, the connecting circular plate 54 is fixedly connected to the collar at the bottom of the hydraulic component 3 through a connecting ring, and an arc-shaped pressing frame 52 is fixedly connected to the edge of the lower surface of the connecting circular plate 54, driving the arc-shaped pressing frame 52 connected to the connecting circular plate 54 and the stamping plate 51 to stamp the workpiece, and the stamping plate 51 first contacts and squeezes the workpiece, so that the arc-shaped pressing frame 52 is compressed and contracted. There are six arc-shaped pressing frames 52, which are distributed in a circular shape on the surface of the connecting circular plate 54, and the lower surface of the arc-shaped pressing frames 52 is fixedly connected to the stamping plate 51.

An inner support member 53 is fixedly connected to the side of the outer surface of the stamping plate 51 . There are three inner support members 53 . The three inner support members 53 are distributed in a circular shape on the surface of the stamping plate 51 , and the inner support members 53 are arranged between the gaps of the two arc-shaped pressing frames 52 .

The inner support member 53 includes a fitting transverse plate 536. When the stamping plate 51 contacts the workpiece, the arc-shaped press frame 52 is compressed and contracted, and the fitting transverse plate 536 arranged on the outside of the stamping plate 51 drives the bent plate 535 and the external plate 534 to rise upward as the arc-shaped press frame 52 contracts. The fitting transverse plate 536 is fixedly connected to the outer surface of the stamping plate 51, and the bent plates 535 are fixedly connected on both sides of the outer surface of the fitting transverse plate 536. The surface of the bent plate 535 is fixedly connected to the external plate 534, thereby reducing the impact force when the hydraulic press is pressed down, reducing the vibration and noise generated by the hydraulic press, reducing the damage to the hydraulic press, and avoiding excessive deformation of the workpiece due to stamping, which affects the stamping accuracy.

The inner surface of the external connecting plate 534 is fixedly connected with an arc plate 533, and the middle of the arc plate 533 is fixedly connected with a U-shaped connecting plate 532, and the surface of the U-shaped connecting plate 532 is fixedly connected with a docking rod 531. After the arc pressure frame 52 shrinks, the upper connecting circular plate 54 is driven downward by the hydraulic component 3, recessed downward, and stuck between the three docking rods 531. The docking rod 531 is pushed by the connecting circular plate 54 so that the U-shaped connecting plate 532 drives the arc plate 533 to move outward, thereby supporting the outer side of the voltage stabilizing component 5 to prevent the connecting circular plate 54 and the stamping plate 51 from being overstressed and unable to maintain balance during stamping.

When in use, the staff pushes the clamping plate 47 to slide in the outer groove plate 42, and rotates the rotating clamp 48 to change its opening and closing angle, thereby clamping and fixing the pressing plate 43, so as to facilitate the replacement of the stamping dies used for different workpieces. Then the staff places the workpiece in the positioning groove 44, and drives the pressure stabilizing component 5 to stamp the workpiece through the hydraulic component 3. The automobile hardware accessories are placed on the pressing platform 4, and the hydraulic component 3 is started so that the piston in the hydraulic component 3 moves downward to contact the workpiece and presses down to stamp the workpiece. During stamping, the pressure stabilizing component 5 first contacts the workpiece and squeezes the workpiece to produce deformation, thereby reducing the impact force when moving downward.

When the hydraulic assembly 3 is punching the workpiece, it is connected to the connecting circular plate 54, driving the arc-shaped pressing frame 52 and the punching plate 51 connected to the connecting circular plate 54 to punch the workpiece. The punching plate 51 first contacts and squeezes the workpiece, causing the arc-shaped pressing frame 52 to contract under pressure.

Under the action of atmospheric pressure, the liquid filling tank 1 opens the one-way valve so that the upper chamber of the main oil cylinder 31 is filled with oil. The main oil cylinder 31 serves as the main driving force. The piston in the main oil cylinder 31 moves downward to contact the workpiece to pressurize the oil in the upper chamber of the main oil cylinder 31. The main oil cylinder 31 drives the movable crossbeam 32 to slide on the surface of the column 33, and makes the stabilizing sliding components 34 on both sides rotate and contract, so that the pressure stabilizing component 5 punches the workpiece placed in the pressing platform 4.

Because the hydraulic press will vibrate when used for a long time, when the main oil cylinder 31 drives the movable beam 32 to slide, the side blocks 341 on both sides move downward with the movable beam 32. Since the compression turning rod 343 is arranged in sections, and one end is connected to the extension rod 346, and the other end is connected to the frame plate 342, the end connected to the extension rod 346 can rotate on the surface of the end connected to the frame plate 342 as the movable beam 32 moves downward. In this way, the movable beam 32 is restricted by the stabilizing sliding components 34 on both sides during the downward process, thereby reducing the vibration frequency, making the movable beam 32 more stable when descending, and improving the service life of the hydraulic press.

The center block 344 is arranged between the compression and turning rods 343. Since the center block 344 is fixedly connected to the compression and turning rod 343 near one end of the extension rod 346, the center block 344 is displaced and rotated as the compression and turning rod 343 moves downward, and the limiting turning rod 345 extending from the center block 344 contacts the frame plate 342. The limiting turning rod 345 is restricted by the frame plate 342, and the compression and turning rod 343 stops rotating, so that the vibrating movable crossbeam 32 is limited by the compression and turning rods 343 on both sides, and the vibration frequency is reduced when moving downward, so as to improve the stability of the movable hydraulic press.

When the stamping plate 51 contacts the workpiece, the arc-shaped pressing frame 52 is compressed and contracted, and the fitting horizontal plate 536 arranged on the outside of the stamping plate 51 drives the bent plate 535 and the external plate 534 to rise upward as the arc-shaped pressing frame 52 contracts, thereby reducing the impact force when the hydraulic press presses downward, avoiding excessive deformation of the workpiece due to excessive stamping, and affecting the stamping accuracy.

After the arc-shaped pressing frame 52 contracts, the upper connecting circular plate 54 is driven downward by the hydraulic assembly 3, concave downward, and stuck between the three docking rods 531. The docking rods 531 are pushed by the connecting circular plate 54 so that the U-shaped connecting plate 532 drives the arc plate 533 to move outward, thereby supporting the outside of the pressure stabilizing assembly 5 to prevent the connecting circular plate 54 and the stamping plate 51 from being overstressed and unable to maintain balance during stamping.

Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field and related fields without creative work should fall within the scope of protection of the present invention. The structures, devices and operating methods not specifically described and explained in the present invention are implemented according to the conventional means in the field unless otherwise specified and limited.
