Description

Technical Field

[0001] The utility model relates to the technical field of forging machines, in particular to a slider adjustment mechanism for a forging machine. Background Art

[0002] The forging machine drives the crank slider mechanism through a gear pair and a clutch, so that the slider and the punch move downward in a straight line. After the forging work is completed, the slider returns upward, the clutch automatically disengages, and at the same time, the automatic device on the crank shaft is turned on, so that the slider stops near the top dead center.

[0003] When a forging press is forging a workpiece, in order to ensure the stability of the slider, a bracket and a guide rod are set on the forging press to guide the slider. After the forging press is started, the slider will slide on the guide rod and drive the punch to move up and down. However, this processing method has the following shortcomings when used: the slider will produce friction with the outer wall of the guide rod when it slides up and down on the guide rod, and the frequent driving of the forging press causes excessive wear on the inside of the slider, which causes a small deviation when the slider slides on the guide rod, and this small deviation will cause the processing position of the punch and the workpiece to change; and because the guide rod is mostly fixedly installed on the forging press, and the input end of the slider is fixedly connected to the drive device, it is inconvenient for the operator to maintain the slider, which in turn affects the efficiency of the forging process of the workpiece. Utility Model Content

[0004] The utility model aims to solve the problem that the slider on the forging machine is easy to wear against the guide rod in the prior art, and proposes a slider adjustment mechanism for the forging machine.

The base is provided with two hydraulic cylinders connected to the bracket, the guide rod is provided with a guide sleeve on the sliding sleeve, and the guide sleeve is integrally connected to a sliding sleeve that matches the guide rod, the sliding sleeve is integrally connected to a support, the slider body is arranged in the support, and a limit component for limiting the slider body is installed in the support.

[0007] Preferably, the bracket is a loop-shaped structure with one side open, and the guide rod is vertically arranged.

[0008] Preferably, the sliding sleeve is an annular structure matched with the guide rod, and the support is a concave structure.

[0009] Preferably, the limiting assembly comprises a positioning rod fixedly mounted on a support, and a pressure plate is placed on the positioning rod, and a reinforcement rod symmetrically arranged and in contact with the slider body is integrally connected to the pressure plate.

[0011] Preferably, a locking bolt detachably connected to the support is threadedly connected to the pressure plate, and a positioning bolt connected to the slider body is threadedly connected to the reinforcement rod.

[0012] Compared with the prior art, the utility model has the following advantages:

[0013] 1. The utility model can reduce the wear of the guide rod on the slider body by arranging matching guide sleeves and sliding sleeves on the guide rod, so that the slider body will not generate friction with the guide rod when moving, which not only improves the service life of the slider body, but also improves the efficiency of forging and pressing of the workpiece.

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0021] Reference Figure 1-Figure 4 A forging machine slider adjustment mechanism includes a forging machine body, and the forging machine body is composed of a base 1, a processing table 2, a bracket 3, a guide rod 4, a driver 5, a slider body 6, and a punch 7. It is supplemented that the forging machine body can perform forging processing on a workpiece, which is a prior art, the processing table 2 can place the workpiece, and the driver 5 can move the slider body 6 and the punch 7 downward, so that the punch 7 can perform forging processing on the workpiece below;

[0022] Two hydraulic cylinders 8 connected to the bracket 3 are provided on the base 1. The bracket 3 is a circular structure with one side open, and the guide rod 4 is vertically arranged. It is supplemented that the upper end of the guide rod 4 is integrally connected to the bracket 3, and the bracket 3 drives the guide rod 4 to move up and disconnect from the base 1 through the extension and retraction of the output end of the hydraulic cylinder 8, so that the operator can disassemble and assemble the guide sleeve 9 from the bottom of the guide rod 4;

[0023] The guide sleeve 9 is provided on the guide rod 4, and the guide sleeve 9 is integrally connected with a slide sleeve 10 that matches the guide rod 4, and the slide sleeve 10 is integrally connected with a support 11, and the slider body 6 is arranged in the support 11, the slide sleeve 10 is an annular structure that matches the guide rod 4, and the support 11 is a concave structure. Figure 2 As shown, when the support 11 rises, the upper end of the support 11 will not deflect from the slider body 6, and the lower end of the support 11 can support the slider body 6;

[0024] By arranging the guide sleeve 9 on the guide rod 4, the sliding sleeve 10 in the guide sleeve 9 can contact the guide rod 4, so that the slider body 6 will not contact the guide rod 4 when it is lifted, and the slider body 6 will not be excessively worn when it is lifted, which not only improves the service life of the slider body 6, but also improves the efficiency of forging the workpiece;

[0025] A limiting assembly for limiting the position of the slider body 6 is installed in the support 11;

[0026] The limiting assembly includes a positioning rod 12 fixedly mounted on the support 11, and a pressure plate 13 is placed on the positioning rod 12, and a positioning hole corresponding to the positioning rod 12 is opened on the slider body 6;

[0027] The pressure plate 13 is threadedly connected with a fixing bolt detachably connected to the positioning rod 12, and the pressure plate 13 is integrally connected with a reinforcement rod 14 symmetrically arranged and in contact with the slider body 6, and the pressure plate 13 is threadedly connected with a locking bolt detachably connected to the support 11, and the reinforcement rod 14 is threadedly connected with a positioning bolt connected to the slider body 6;

[0029] The functional principle of the utility model can be explained through the following operation modes:

[0030] When the forging machine body is processing the workpiece;

[0031] The workpiece is placed on the processing table 2, and the driver 5 drives the slider body 6 to move downward. When the slider body 6 moves, it drives the support 11 and the punch 7 to move downward synchronously. When the support 11 moves downward, it drives the guide sleeve 9 and the sliding sleeve 10 to slide on the guide rod 4. When the punch 7 moves downward, it can process the workpiece on the processing table 2 for forging.

[0032] After the workpiece is forged, the slider body 6 moves up to the initial position;

[0033] When the sleeve 10 is damaged, the output end of the hydraulic cylinder 8 drives the bracket 3 to move upward, so that the bracket 3 is disconnected from the base 1;

[0034] Remove the positioning bolt to disconnect the reinforcing rod 14 from the slider body 6, remove the fixing bolt and the locking bolt to disconnect the pressure plate 13 from the positioning rod 12 and the support 11;

[0035] Apply pressure to the support 11 and the guide sleeve 9, so that the support 11 and the guide sleeve 9 slide downward for a certain distance and are disconnected from the guide rod 4;

[0036] The operator sets the unused guide sleeve 9 on the guide rod 4 and lifts the guide sleeve 9 so that the guide sleeve 9 drives the support 11 to contact the slider body 6. When the support 11 moves upward, it drives the positioning rod 12 to extend into the positioning hole in the slider body 6. The pressure plate 13 is placed on the positioning rod 12, and the pressure plate 13 is connected to the positioning rod 12 with a fixing bolt, and the pressure plate 13 is connected to the support 11 with a locking bolt, and the reinforcement rod 14 is connected to the slider body 6 with a positioning bolt.
