Description

Technical Field

[0001] The utility model relates to the technical field of forging machine slider adjustment, in particular to a forging machine slider lifting and lowering adjustment device. Background Art

[0002] Forging press is a device used for cold processing of metal and machinery. It only changes the external shape of the metal. Forging press includes plate rolling machine, plate shearing machine, punching machine, press machine, hydraulic press, oil press, bending machine, etc. Mechanical pressure forging press converts the rotational motion of the motor into the linear reciprocating motion of the slider through the crank slider mechanism to perform forging processing on the blank.

[0003] When using a mechanical pressure forging machine, the slider is driven downward by the wedge block to drive the upper module and the lower module to close in order to perform forging operations on the workpiece. When the downward driving pressure of the mechanical pressure forging machine is fixed, the spacing between the upper module and the lower module controls the amount of work applied to the workpiece. If the work needs to be adjusted, the spacing between the upper module and the lower module is adjusted. However, in the prior art, since the upper module is connected to the slider, when the upper module is moved downward, the slider moves downward together, thereby separating the slider from the wedge block. At this time, the wedge block cannot drive the slider to perform forging operations. Utility Model Content

When adjusting the movable long block 5, the position of the movable long block 5 is only adjusted at the upper end of the guide slide groove 4 through the limit of the limit card plate 6, and the lower end of the guide slide groove 4 ensures that the movable long block 5 has enough downward movement distance;

[0028] A pressure slider 7 and an upper module 8 are also provided on the machine body 1. The pressure slider 7 and the upper module 8 are respectively arranged at the upper and lower ends of the movable long block 5. When the pressure slider 7 abuts against the wedge-shaped driving block 2, the wedge-shaped driving block 2 can drive the pressure slider 7 downward to close the lower module 3 and the upper module 8, and perform forging operation on the workpiece in the lower module 3; a driving mechanism, which is arranged in the movable long block 5 and is used to drive the pressure slider 7 and the upper module 8.

[0029] The upper end of the machine body 1 is fixedly connected to a driving motor, and a rotating rod 9 is fixedly sleeved at the output end of the driving motor. The end of the rotating rod 9 away from the driving motor is pin-connected to a connecting rod 10. A fixed bracket 11 is fixedly installed on the machine body 1, and an inclined slide groove is opened at the lower end of the fixed bracket 11. The wedge-shaped driving block 2 is slidably sleeved in the inclined slide groove, and the wedge-shaped driving block 2 is pin-connected to the connecting rod 10. Figure 1 and attached Figure 2 As shown, the driving motor can drive the rotating rod 9 to rotate, and the rotating rotating rod 9 drives the connecting rod 10 to move rightward, and at the same time, the connecting rod 10 drives the wedge-shaped driving block 2 to slide rightward in the inclined slide groove, and the wedge-shaped driving block 2 drives the pressed sliding block 7 to move downward;

[0030] And as attached Figure 3 As described, the lower end of the lower module 3 is provided with an opening, and the opening sliding sleeve is provided with a push plate 12, and the push plate 12 is installed with a cylinder. After the forging operation of the workpiece is completed, the push plate 12 is used to push the workpiece out of the lower module 3 by the cylinder, and the moving long block 5 is pushed to the middle end of the guide chute 4, so as to facilitate the position adjustment of the moving long block 5 next time;

[0031] The driving mechanism includes an adjustment chamber, an adjustment motor 13, a rotating gear 14 and a vertical slide 15. The adjustment chamber is opened in the moving long block 5.

At the same time, the first rack 16 and the second rack 17 are respectively fixedly connected to the pressure slide block 7 and the upper module 8.

[0033] The functional principle of the utility model can be explained through the following operation modes:

[0034] When the distance between the lower module 3 and the upper module 8 needs to be reduced, the moving long block 5 is first pushed downward to allow the moving long block 5 to move to the middle end of the guide slot 4, and at the same time, the moving long block 5 abuts against the limiting card plate 6 to limit the moving long block 5 at this position;

[0035] Then, the adjusting motor 13 is started, and the output end of the adjusting motor 13 drives the rotating gear 14 to rotate. Since the first rack 16 and the second rack 17 are meshed with the rotating gear 14 for transmission, the first rack 16 and the second rack 17 move in opposite directions. At this time, the first rack 16 moves upward, and the second rack 17 moves downward, so that the first rack 16 drives the pressure slider 7 to move upward, and the second rack 17 drives the upper module 8 to move downward, and the upper end of the pressure slider 7 is abutted against the lower end of the wedge-shaped driving block 2, and then the limit clamping plate 6 is pulled out to release the limit of the moving long block 5.
