Description

Technical Field

[0001] The utility model relates to a flange forging surface processing mechanism, belonging to the flange processing field. Background Art

[0002] Flange pickling and passivation is a metal surface treatment process, which is mainly used to improve the corrosion resistance of stainless steel flanges. The flange forging is placed in a storage tank containing pickling and passivation liquid, so that the flange forging and the pickling and passivation liquid react chemically. Since a large number of flange forgings are added to the storage tank at a time, there is a situation where the supported part of the flange forging is not in sufficient contact with the pickling and passivation liquid. In addition, due to the large number of flange forgings in the storage tank, it is difficult to adjust the position of the flange forging. The flange forging needs to be taken out and adjusted before being lowered into the storage tank. This method makes the flange forging processing efficiency low, so it is necessary to design a flange forging surface processing mechanism that improves the pickling and passivation efficiency of flange forgings. Utility Model Content

[0003] In view of the shortcomings of the prior art, the purpose of the utility model is to provide a flange forging surface processing mechanism to solve the problems raised in the above-mentioned background technology. The utility model realizes the movement of the flange forging during the pickling and passivation process so that the supported part of the flange forging is in full contact with the pickling and passivation liquid.

[0004] In order to achieve the above-mentioned purpose, the utility model is realized by the following technical scheme: a flange forging surface processing mechanism, comprising a liquid storage tank, a bracket is slidably installed in the liquid storage tank, the upper surface of the bracket is recessed downward to form a plurality of equally spaced arc grooves for storing flange forgings, a top plate is provided directly above the liquid storage tank, two vertically arranged first electric push rods are installed on the lower surface of the top plate, a corrosion-resistant connecting rod is installed on the movable end of the first electric push rod, the lower end of the connecting rod is connected and fixed with the bracket, an adjustment plate arranged parallel to the top plate is provided on one side of the top plate, two guide holes are provided on the side of the adjustment plate facing the top plate, a guide rod is inserted in the guide hole, one end of the guide rod is connected and fixed with the top plate, two clamping screws for limiting the relative position of the guide rod and the adjustment plate are threadedly connected to the upper surface of the adjustment plate, two vertically arranged second electric push rods are installed on the upper surface of the adjustment plate, a cross plate is installed on the movable end of the second electric push rod, a plurality of toggle rods are evenly installed on the lower surface of the cross plate, and a soft head in contact with the annular side surface of the flange forging is installed on the lower end of the toggle rod.

[0005] Furthermore, two straight cylinders are installed on the upper surface of the adjustment plate, the straight cylinders are communicated with the guide holes, a positioning plate is installed in the middle position of the straight cylinder, a threaded hole is opened in the middle position of the upper surface of the positioning plate, the clamping screw is threadedly connected in the threaded hole, and slip rings are provided on the upper side and the lower side of the positioning plate, the slip rings are sleeved on the clamping screws and fixedly connected to the clamping screws, the slip rings are slidably installed in the straight cylinder, and the distance between the two slip rings is half the height of the straight cylinder.

[0006] Furthermore, a plurality of transverse holes are provided on both side walls of the arc-shaped groove, and a plurality of vertical holes communicating with the arc-shaped groove are evenly provided on the bottom of the bracket.

[0007] Furthermore, two mounting holes are provided on the upper surface of the adjustment plate, and the cylinder end of the second electric push rod is installed in the mounting holes.

[0008] Furthermore, two arm plates are installed on a side of the top plate away from the adjustment plate, and two fixing holes are provided on a side of the upper surface of the arm plate away from the top plate.

[0009] Furthermore, the length of the bracket is smaller than the length of the inner space of the liquid storage tank, and the width of the bracket is smaller than the width of the inner space of the liquid storage tank.

[0010] Beneficial effects of the utility model:

[0011] 1. Limit the position of the top plate, then insert the flange forging into the arc groove on the bracket to realize the vertical arrangement of the flange forging, control the extension of the first electric push rod to lower the bracket into the liquid storage tank, so that the flange forging is immersed in the pickling passivation liquid in the liquid storage tank, which is convenient for taking and placing the flange forging.

[0012] 2. A corrosion-resistant connecting rod is used to connect the first electric push rod and the bracket, so that when the bracket is lowered into the liquid storage tank, the first electric push rod does not come into contact with the pickling passivation liquid, thereby protecting the first electric push rod.

[0013] 3. A plurality of vertical holes connected to the arc groove are opened at the bottom of the bracket, and transverse holes are opened on the inner wall of the arc groove. When the bracket is lifted to the upper side of the liquid storage tank, the pickling and passivation liquid remaining in the arc groove and the pickling and passivation liquid on the surface of the flange forging flow back into the liquid storage tank.

[0014] 4. Adjust the position of the adjustment plate along the guide rod, so that the position of the cross plate changes, that is, the relative position of the toggle rod and the flange forging inserted in the arc groove changes, so that the soft head at the lower end of the toggle rod can contact different parts of the flange forging as needed.

[0015] 5. Control the extension of the second electric push rod, and the horizontal plate drives the toggle rod to move downward. After the soft head contacts the annular side of the flange forging, it squeezes the flange forging downward, so that the flange forging rotates in the arc groove, so that the part of the flange forging supported by the arc groove is transferred to the area away from the inner wall of the arc groove, so that the flange forging is toggled during the pickling and passivation process, so that the supported part of the flange forging is fully in contact with the pickling and passivation liquid, thereby improving the pickling and passivation efficiency.

[0016] 6. Install the positioning plate in the middle of the straight tube. When the clamping screw is turned, the clamping screw drives the two slip rings to slide in the straight tube. At this time, the threaded connection between the clamping screw and the threaded hole is always in a hidden state to prevent small debris from entering the threaded hole at will and affecting the turning of the clamping screw.
