Description

Technical Field

[0001] The invention relates to the technical field of precision forging machines, and in particular to a height-adjustable workpiece supporting device for a precision forging machine. Background Art

[0002] The precision forging machine is a fast and precise forging equipment. It is a short-stroke press that uses several symmetrical hammers to forge metal blanks at a high frequency. The hammer has two movements: ① The eccentric shaft driven by the motor drives the connecting rod to make the hammer reciprocate for forging; ② The adjustment mechanism adjusts the position of the connecting rod through the eccentric sleeve to change the opening size of the hammer to obtain different forging sizes. During forging, the blank is sent into the forging box by the chuck of the operating machine for reciprocating forging. Loading, unloading and conveying are all controlled manually or automatically in the control room. After continuous improvement, the precision forging machine has gradually become larger and serialized. The forging pressure of each hammer of the precision forging machine is 15 to 2500 tons, and the blows are 2000 to 125 times per minute. The diameter of the forged blank is 20 to 850 mm. The precision forging machine has developed from manual and semi-automatic to automatic control, and in the 1970s it developed to computer control.

[0003] When a precision forging machine is forging slender materials, in order to prevent the heated forging material from bending and deforming due to gravity and affecting the forging quality, a workpiece support device that plays an auxiliary supporting role is used to support the forging material near the forging head to reduce or eliminate the bending deformation of the forging material. However, most traditional workpiece support devices are fixedly installed, and it is inconvenient to adjust them after installation, resulting in that they can only be used for workpieces of fixed sizes. When changing to forge workpieces of different sizes, they often need to be re-calibrated and adjusted, which is inconvenient to use. Summary of the invention

[0015] Optionally, two tracks are symmetrically installed between the two horizontal plates, two sliding rods are symmetrically installed inside the two tracks, and both ends of the two metal strips are threadedly connected to the sliding rods close to them through screws.

[0039] As a technical optimization solution of the present invention, the electric telescopic rods 20 are rotatably installed inside the two rotating rods 18, and the telescopic ends of the two electric telescopic rods 20 are installed with arc-shaped clamping plates 17. The third driving devices are preset inside the two rotating rods 18, and the output ends of the two third driving devices are respectively connected to the two electric telescopic rods 20, so as to drive the two electric telescopic rods 20 and the arc-shaped clamping plates 17 to rotate and adjust; the telescopic ends of the two electric telescopic rods 20 are extended and retracted, which can drive the two arc-shaped clamping plates 17 to move towards or away from each other.

[0040] As a technical optimization solution of the present invention, the auxiliary shaping mechanism includes two transverse plates 8, which are respectively installed on the outer wall of one side of the two connecting plates 15, and the tops of the two transverse plates 8 are provided with second slide grooves 21, and the insides of the two second slide grooves 21 are provided with second sliders 28, and the tops of the two second sliders 28 are provided with moving plates 22. The insides of the two second slide grooves 21 are preset with first linear motors, and the two first linear motors can respectively drive the two second sliders 28 to move back and forth inside the second slide grooves 21, and drive the two moving plates 22 to move back and forth.

[0041] As a technical optimization solution of the present invention, the outer wall of the side where the two moving plates 22 are close to each other is provided with a groove, and the inside of the two grooves is slidably installed with a moving block 23, and a rotating block 24 is installed between the two moving blocks 23 for common rotation, and a shaping block 25 is installed on the top of the rotating block 24, and a cleaning brush 26 is installed on the bottom of the rotating block 24. Telescopic cylinders are preset inside the two grooves, and the telescopic ends of the two telescopic cylinders are connected to the bottom ends of the corresponding moving blocks 23. With the telescopic ends of the telescopic cylinders, the two moving blocks 23 can be driven to move up and down inside the corresponding grooves; a third driving device is preset inside one of the moving blocks 23, and the output end of the third driving device is connected to the rotating part of the rotating block 24, so that the rotating block 24 can be driven to rotate and adjust.

[0042] As a technical optimization solution of the present invention, the outer wall of the adjacent side of the two horizontal plates 8 is provided with a rectangular groove 31, and the inside of the two rectangular grooves 31 is installed with a telescopic curtain 29, and the ends of the two telescopic curtains 29 away from the rectangular grooves 31 are installed with a metal strip plate 30. By pushing the two metal strip plates 30 to move in the direction of approaching each other, the two telescopic curtains 29 can be driven to extend from the inside of the corresponding rectangular grooves 31, so that the two unfolded telescopic curtains 29 are located below the multiple support rollers 6, and can receive the debris falling from the surface of the workpiece; the telescopic curtains 29 are made of high temperature resistant cloth in the prior art.

[0043] As a technical optimization solution of the present invention, two tracks 27 are symmetrically installed between the two horizontal plates 8, two slide bars 33 are symmetrically installed inside the two tracks 27, and both ends of the two metal strips 30 are threadedly connected to the slide bars 33 close to them through screws 32. After the two slide bars 33 move toward the approaching direction and abut against each other inside the track 27, they can be manually connected and fixed by corresponding fixing buckles, so that the two telescopic curtains 29 can be limited and fixed in the unfolded state.

[0044] In the present invention, when the user uses the device, the base plate 1 is installed in the processing area of ​​the precision forging machine by passing multiple bolts through the mounting holes 2. According to the actual needs of supporting different workpieces, the drive motor 10 is controlled to rotate forward and reversely, and the two double-headed screws 4 are driven to rotate forward or reversely together with the help of two drive belts 11, so that the two corresponding moving seats 14 can move in a direction close to or away from each other, and the height of the two mounting plates 9 and multiple support rollers 6 can be adjusted with the help of the two connecting rods 5 above, so that the device can be flexibly adjusted according to the height requirements of different workpiece supports during the subsequent precision forging machine processing.

[0045] After the precision forging machine processes the workpiece into a slender strip, it needs to use multiple support rollers 6 of the support device to assist in supporting it, so as to prevent the slender strip from bending downward due to its own weight. By controlling the telescopic ends of the multiple electric telescopic rods 20 to extend together, the multiple arc-shaped clamping plates 17 are driven to move toward the middle part of the multiple support rollers 6, thereby assisting in limiting the workpiece on the top of the multiple support rollers 6, and preventing the workpiece from being offset when it is on the top of the multiple support rollers 6, which causes the workpiece itself to deform.

[0046] After the precision forging machine processes the workpiece into a slender strip state, the inner walls of the multiple arc-shaped clamps 17 can be abutted and matched with the outer wall of the workpiece, so that at this time, after the two matching arc-shaped clamps 17 contact the outer wall of the workpiece in the approaching direction, the diameter of the workpiece after processing can be detected in real time. After ensuring that the inner walls of the multiple arc-shaped clamps 17 can be tightly abutted against the outer wall of the workpiece, it can be concluded that the workpiece has been forged to a suitable state by the precision forging machine. There is no need for manual hand-held measuring tools to measure and detect the workpiece, which avoids close contact between the staff and the workpiece, and indirectly has a protective effect on the safety of the staff.

[0047] At the same time, before the device is used, the two sliding bars 33 can be manually pushed to move in the direction of approaching each other, thereby driving the two metal strips 30 to move in the direction of approaching each other, until the two metal strips 30 are abutted, and the two first sliders 19 inside the two first slide grooves 16 are controlled to drive the corresponding electric telescopic rods 20 and the arc clamping plate 17 to move in the direction of moving away from each other, so that the two first sliders 19 drive the electric telescopic rods 20 and multiple components to move to the corresponding positions of the sliding bars 33, and after controlling the multiple rotating rods 18 to rotate downward to an inclined state, the telescopic end of the electric telescopic rod 20 is controlled to drive the arc clamping plate 17 to move in the direction close to the sliding bar 33, so that the positions of the multiple sliding bars 33 at this time can be assisted by the multiple electric telescopic rods 20 and the arc clamping plate 17 to clamp and fix them, so that the staff can connect and fix the two groups of sliding bars 33 in turn with the two buckles, so that the two telescopic curtains 29 can be horizontally unfolded below the multiple support rollers 6, and the debris falling down during the process of supporting the workpiece above the multiple support rollers 6 can be received to avoid contamination of the device.

[0048] After the precision forging machine completes the processing of the workpiece, the first sliders 19 inside the two first slide grooves 16 can be controlled to move repeatedly in the direction of approaching and moving away from each other, thereby driving the two groups of arc-shaped clamping plates 17 to move back and forth on the outer wall of the workpiece to scrape off the debris remaining on the surface of the workpiece, and can continue to control the operation of the mechanism inside the precision forging machine that can drive the workpiece to rotate, driving the workpiece to rotate, so that the two groups of arc-shaped clamping plates 17 can more comprehensively clean and remove the debris remaining on the outer wall of the workpiece, and the cleaned debris can also fall downward on the top of the two unfolded telescopic curtains 29, avoiding the problem of debris on the outer wall of the workpiece constantly falling downward during the subsequent transfer of the workpiece to other equipment, thereby polluting the processing environment.

[0049] At the same time, while controlling the two groups of arc-shaped clamps 17 to move back and forth on the surface of the processed workpiece, if the two groups of arc-shaped clamps 17 are controlled to move back and forth and the movement is not smooth after they abut against the outer wall of the workpiece, it can be quickly determined that there is deformation at a certain position of the processed workpiece, which is convenient for quickly screening out unqualified workpieces and improving the forging accuracy of the workpiece.

[0050] Furthermore, if it is determined that a certain position of the workpiece has a deformation problem, the workpiece can be rotated and adjusted again with the help of a mechanism inside the precision forging machine that drives the workpiece to rotate continuously, so that the deformation position of the workpiece is directly above the rotating block 24, and the telescopic ends of the two sets of electric telescopic rods 20 are extended to drive the two sets of arc-shaped clamps 17 to clamp and fix the two ends of the workpiece, and then the two moving blocks 23 are controlled to drive the rotating block 24 to move upward together, so that the shaping block 25 on the top of the rotating block 24 contacts the deformation position of the workpiece, and as the rotating block 24 and the shaping block 25 continue to move upward, the deformation position of the workpiece can be squeezed, thereby assisting in extruding and shaping the deformation position of the workpiece, without the need to continue to use the precision forging machine for secondary processing of the workpiece, thereby improving the processing efficiency of the precision forging machine for the workpiece.

[0051] After the two sets of arc-shaped clamping plates 17 clean the debris on the surface of the workpiece, the workpiece can be grabbed and transported to other equipment with the help of a grabbing mechanism arranged near the precision forging machine for subsequent other processing. At this time, the rotating block 24 can be controlled to rotate 180 degrees, driving the cleaning brush 26 to rotate upward to the top of the rotating block 24, and then the two moving blocks 23 are controlled to drive the rotating block 24 to move downward to the lowest position, so that the cleaning brush 26 can now contact the multiple support rollers 6. As the two second sliding blocks 28 move back and forth inside the second slide trough 21, the cleaning brush 26 is driven to clean the outer walls of the multiple support rollers 6, and the debris attached to the outer walls of the multiple support rollers 6 is cleaned and removed, which is convenient for the subsequent use of the multiple support rollers 6.

[0052] If the grabbing mechanism near the precision forging machine fails, resulting in the inability to quickly transfer the processed workpiece to other equipment, at this time, one of the rotating plates 7 can be controlled to drive the two rotating rods 18 and other components to rotate 180 degrees in the direction away from the device, and the corresponding two electric telescopic rods 20 can be controlled to rotate 90 degrees by themselves, so that the two arc-shaped clamping plates 17 rotate to a horizontal state, and after the telescopic ends of the two electric telescopic rods 20 are controlled to extend to the maximum length together, the telescopic ends of the other two electric telescopic rods 20 are controlled to drive the two arc-shaped clamping plates 17 to extend above the device together, so that the processed workpiece can be pushed downward from the top of the multiple support rollers 6, and at this time, one of the rotating plates 7, the two rotating rods 18 and the two electric telescopic rods 20 with their telescopic ends in an extended state are used as a guiding unloading mechanism, which is convenient for guiding the workpiece falling downward, so that it can be quickly unloaded even after the grabbing mechanism fails, so as to avoid affecting the subsequent processing of other workpieces and reduce the impact on the processing of multiple workpieces by the precision forging machine.

[0053] After cleaning the multiple support rollers 6, the rotating block 24 can be controlled to rotate and reset, so that the cleaning brush 26 can now naturally abut against the tops of the two telescopic curtains 29. As the two second sliders 28 drive the rotating block 24 and the cleaning brush 26 to move, the debris collected on the tops of the two telescopic curtains 29 can be pushed down into a preset collection box for collection, thereby achieving the effect of automatically cleaning the collected debris without the need for subsequent manual cleaning.

[0054] If the subsequent device is not used for a long time, the screws 32 connecting the two ends of the two metal strips 30 with the sliding rods 33 can be removed, so that the metal strips 30 can be pulled downward at this time, driving the telescopic curtain 29 to pass through the bottom of the double-headed screw 4, and then the telescopic curtain 29 is pulled upward to cover the top of the two rotating plates 7, so that the two telescopic curtains 29 can have a shielding and protective effect on multiple components in the device when the device is not in use, avoiding dust and other debris from adhering to the surface of the components in the device, which will affect the subsequent use of the device.

The preferred embodiments do not describe all the details in detail, nor do they limit the invention to the specific implementation methods described. Obviously, many modifications and changes can be made according to the content of this specification.
