Description

Technical Field

[0001] The invention belongs to the technical field of forging equipment, and in particular relates to a forging manipulator hanging system. Background Art

[0002] The forging manipulator can realize the functions of clamping, advancing, retreating, lifting, rotating and translating the forging material, and is one of the indispensable and important equipment in the automated forging operation. The hanging system is located in the middle of the forging manipulator, and adopts multiple parallel hinge four-bar mechanisms and rotating levers and multiple hydraulic cylinders for linkage. The power source is provided by high-pressure hydraulic oil. Under the control of the computer, the parallel lifting, up and down tilting, left and right lateral movement, left and right lateral swing, buffer balance and other main actions of the clamp rod are fully realized to meet the forging process requirements.

[0003] The hanging system is mainly subjected to the tensile, compressive and rotating forces during the forging process of the steel billet, as well as the gravity of the jaws, spindle and forging material. It is the most frequently moved and most easily damaged part of the forging manipulator. The two ends of the spindle in the hanging system are respectively connected to the driving rods of the leveling cylinder. The spindle is connected to the clamp body through the grate bar. The connection point between the grate bar and the spindle is the hanging point of the clamp body and the forging material. The function of the spindle is to transmit the action of the leveling cylinder to the clamp body. The hanging system also includes a connecting rod assembly, which is a U-shaped part, which is formed by two L-shaped parts with the same structure connected by flanges.

[0004] When the forging manipulator clamps the forging material for forging, the jaws need to rotate (forging round materials or adjusting the surface). Due to the free forging form, in order to improve production efficiency, the hammer head on the forging machine is usually pressed on the forging material before the forging material stops rotating, causing the forging material to stop rotating suddenly. The reaction force of the forging material acts on the jaws, and then is transmitted to the spindle through the grate bars, causing the axial movement of the spindle. The axial movement of the spindle causes the radial vibration of the driving rod of the lifting cylinder. First, the radial vibration of the driving rod of the lifting cylinder will cause: eccentricity of the driving rod of the lifting cylinder, impact of the cylinder barrel, failure of the sealing of the lifting cylinder, and oil leakage. Secondly, the radial vibration of the driving rod of the lifting cylinder will cause the driving rod of the lifting cylinder to bend and deform. The above two factors will shorten the service life of the lifting cylinders on both sides, and the lifting and lowering will be out of sync, which will cause the flange and flange bolts of the connecting rod assembly to be severely damaged. In severe cases, the hollow boom of the spindle and the spindle outer casing will tilt, which will cause the jaws to tilt, affecting the forging quality.

[0005] Therefore, it is necessary to provide an improved technical solution to address the above-mentioned deficiencies in the prior art. Summary of the invention

In this embodiment, the rod end joint bearing 2 includes a rolling ball 201, a bearing sleeve 202, an outer ring 203 and a rod end 204. Specifically: the rolling ball 201 is sleeved and fixed on the main shaft 8; the bearing sleeve 202 is sleeved on the rolling ball 201 and rolls with the rolling ball 201. The outer ring 203 is sleeved and fixed on the bearing sleeve 202. The outer ring 203 and the rod end 204 are integrally formed, and the rod end 204 is threadedly connected to the output rod of the leveling cylinder 9 so that the rod end 204 is fixed on the output rod of the leveling cylinder 9. In other embodiments, the outer ring 203 and the rod end 204 can also be fixedly connected, such as welding. The rod end joint bearing 2 is provided to compensate for the axial deviation of the driving rod of the leveling cylinder 9, so that the force of the leveling cylinder 9 does not occur unbalanced load, ensure that the driving rod of the leveling cylinder 9 does not bend, and ensure the service life of the cylinder shaft seal.

[0063] The fixed connection form between the rod end joint bearing 2 and the driving rod of the lifting cylinder 9 is as follows: the rod end 204 is provided with an internal threaded hole, and the front end portion of the driving rod of the lifting cylinder 9 is an external threaded portion, and the external threaded portion is threadedly matched with the internal threaded hole to realize the fixed connection between the rod end joint bearing 2 and the output rod of the lifting cylinder 9.

The cover 1 cooperates with the ball joint baffle 4 to prevent the rod end joint bearing 2 from axial movement.

[0065] like Figure 7 As shown, the connecting rod assembly 3 is a U-shaped member, which includes a bottom arm 3011 and two side arms 3012 arranged opposite to each other. The two side arms 3012 are provided with shaft holes for the main shaft 8 to pass through, so as to realize the fixed connection between the main shaft 8 and the connecting rod assembly 3. A bearing seat 302 is provided on the outer side of the bottom arm 3011, and the connecting rod assembly 3 is hinged to the frame of the forging operating machine through the hinge shaft in the bearing seat 302, and the frame of the forging operating machine blocks the connecting rod assembly 3 in the left and right directions, so as to realize the limit of the connecting rod assembly 3 in the left and right directions.

[0066] like Figure 8As shown, the connecting rod assembly 3 is formed by two L-shaped members 301 connected together, each L-shaped member 301 includes a side arm 3012 and a partial bottom arm 3011, and a flange is provided at one end of the partial bottom arm 3011 away from the side wall 3012. The two L-shaped members 301 are flange-connected, and the outer diameter of the flange 303 is φ400mm. The flange 303 also includes a flange sleeve 3033, which is arranged between the hole wall of the flange hole 3032 and the flange bolt 3031 to prevent the flange bolt 3031 from being cut off, resulting in failure of the flange connection. In addition, when the shear force is too large to cause the flange sleeve 3033 to be damaged, it is easier to remove the damaged flange sleeve 3033 from the flange hole 3032 than the flange bolt 3031 is damaged, which reduces the difficulty and time of maintenance and ensures maintenance efficiency.

[0067] like Figure 2 As shown, the hollow boom 7 is a hollow structure, which is sleeved on the main shaft 8 and fixedly connected: a through hole is provided on the hollow boom 7, and a mounting hole is provided on the main shaft 8 corresponding to the through hole. The diameter of the locating pin ranges from 40 to 60 mm. Optionally, the diameter of the locating pin 6 is 50 mm, and the hollow boom 7 is inserted into the mounting hole and the through hole to achieve a fixed connection between the hollow boom 7 and the main shaft 8. In this embodiment, an annular protrusion 701 is provided on the hollow boom 7, and the through hole is provided on the annular protrusion 701, and the annular protrusion 701 forms a locating pin mounting seat.

[0068] like Figure 4 and Figure 6 As shown, the positioning pin 6 has a radially enlarged head 601, and the diameter of the head 601 is φ98mm. The above-mentioned through hole on the hollow boom 7 is a countersunk hole 7011 to accommodate the head 601 of the positioning pin 6. The head 601 is provided with a light hole 6011, and the number of the light holes 6011 is 4, and adjacent light holes 6011 are arranged at 90° intervals. The axis of the light hole 6011 is parallel to the axis of the positioning pin 6, and a fixing threaded hole 7012 is provided on the main shaft 8 at the edge of the hole of the mounting hole, and the fixing threaded hole 7012 corresponds to the light hole 6011. The fixing bolt passes through the light hole 6011 and is connected to the fixing threaded hole 7012 to achieve the fixation of the positioning pin 6 and the hollow boom 7.

[0069] The head 601 is also provided with two top-mounted threaded holes 6012, which are symmetrically arranged. The axis of the top-mounted threaded hole 6012 is parallel to the axis of the positioning pin 6, and a top-mounted bolt is installed in the top-mounted threaded hole 6012. When the top-mounted bolt is fed, it pushes against the hollow boom 7 to push the head 601 out of the countersunk hole 7011, so as to facilitate the removal of the positioning pin 6.

[0070] The end of the hollow boom 7 is a stress concentration site, and the stress concentration site is designed as a wall thickening portion 702 to increase the structural strength of the end and prevent the end of the hollow boom 7 from being damaged.

[0071] There are two grate bars 5, the upper ends of which are sleeved on the main shaft 8, and the lower ends are connected to the clamp rod of the forging manipulator. The purpose is to transmit the movement of the leveling cylinder 9 to the clamp rod through the main shaft 8, the rod end joint bearing 2 and the grate bars 5.

[0072] As shown in FIG. 1 , the hollow suspension arm 7 and the grate bars 5 are both arranged between the two side arms 3012 , and the two grate bars 5 are respectively arranged at the two ends of the hollow suspension arm 7 , and the hollow suspension arm 7 cooperates with the two side arms 3012 to clamp the two grate bars 5 in the left and right directions.

[0073] Because the connecting rod assembly 3 is positioned by the frame of the forging manipulator in the left-right direction, the connecting rod assembly 3 and the hollow boom 7 are arranged between the two side arms 3012 of the connecting rod assembly 3 and clamped by the two side arms 3012 of the connecting rod assembly 3, the positions of the connecting rod assembly 3 and the hollow boom 7 can be positioned in the left-right direction to prevent the connecting rod assembly 3 and the hollow boom 7 from moving on the main shaft 8. The hollow boom 7 and the main shaft 8 are fixed by the positioning pin 6 to form an integrated structure. Because the hollow boom 7 is positioned in the left-right direction, the main shaft 8 is also positioned in the left-right direction.

[0074] When the reaction force of the forging acts on the jaws and is then transmitted to the spindle 8 through the grate bars 5, the grate bars 5 and the spindle 8 are both positioned in the left-right direction, and the spindle 8 will not move axially, thereby solving the subsequent problems caused by the movement of the spindle 8.

[0075] The present invention is mainly used for a 20MN fast forging manipulator, and can certainly be used for other types of forging manipulators according to actual needs.
