Technical Field

[0001] The utility model relates to the technical field of metal salt bath nitriding treatment equipment, in particular to a cast iron pot nitriding treatment pot hanging device. Background Art

[0002] In recent years, fatigue resistance, wear resistance, high strength and good appearance have become the basic requirements for the metal surface of cast iron pot blanks. The existing surface treatment of metal parts is mainly salt bath nitriding treatment.

[0003] The general method of hanging cast iron pots in salt bath nitriding is to use a pin with a round hole. First, use the pin to put the untreated cast iron pot blank on the simple pot hanging bracket, and then use the steel wire to pass through the round hole of the pin. The pin needs to be inserted every time the cast iron pot blank is put on and off the rack, which is time-consuming and labor-intensive, and reduces production efficiency. When the steel wire fixing the pin breaks, the pot blank is easy to fall into the salt bath furnace and is not easy to fish out, affecting the production progress. The pin and steel wire need to be cleaned every time they are removed from the rack. If the cleaning is not thorough, the salt solution in the salt bath furnace will be contaminated when it is used again.

[0004] The simple hanging pot bracket cannot bear too much weight due to the unstable structure between the various parts, which limits the number of cast iron pot blanks processed during each salt bath nitriding, affecting the production progress. When the cast iron pot blank is overweight, it is easy to twist and deform, and cannot be used anymore, which increases the production cost. The cast iron pot has poor fixing effect and is easy to fall off during the process.

[0005] Therefore, improvements are made to address the above problems. Utility Model Content

A plurality of hanging rods 4-4 are fixedly connected around the top of the annular frame 1. A plurality of sleeve frames 4-5 are fixedly connected to the outside of the dispersion frame 4-3. The sleeve frames 4-5 are sleeved on the outside of the hanging rod 4-4. The outside of the center rod 4-2 is sleeved with a spring 4-6, and the spring 4-6 is located in the bottom cavity 4-1. Internally, the lower end of the center rod 4-2 is fixedly connected to the base plate 4-7, the bottom of the center frame 2 is fixedly connected to the wire wheel 4-8, the bottom of the center frame 2 is fixedly connected to the stabilizing frame 4-9, the movable set in the stabilizing frame 4-9 is connected to the pull rope 4-10, one end of the pull rope 4-10 passes around the wire wheel 4-8 and is connected to the top of the base plate 4-7, one end of the wire wheel 4-8 is fixedly connected to the handle 4-11, and a docking groove 4-12 is provided at the bottom of the base plate 4-7, the outer surface of the center frame 2 is rotatably connected to the bracket 4-13 through a pin shaft, and the lower end surface of the bracket 4-13 is fixedly connected to the pull rod 4-14.

[0035] In this embodiment, in order to achieve the effect of hanging the cast iron pot firmly and not falling off, a pot hanging clamping assembly 4 is designed. A center rod 4-2 connected to the top and bottom is opened inside the center frame 2. A spring 4-6 is sleeved on the outside of the center rod 4-2. The center rod 4-2 can move upward. A dispersion rack 4-3 is connected to the top of the center rod 4-2. Each end of the dispersion rack 4-3 is fixed with a sleeve rack 4-5, which is fitted and connected with the hanging rod 4-4 on the top of the center frame 2. The hanging rod 4-4 is used When hanging the cast iron pot, the sleeve frame 4-5 is pressed and fixed, and the pressing effect is maintained by the elastic force of the spring 4-6, so that it will not loosen and cause the cast iron pot to fall off. In order to facilitate the lifting of the dispersion frame 4-3, a pull rope 4-10 is connected to the bottom of the center frame 2 through a stabilizing frame 4-9 and a wire wheel 4-8. The other end of the pull rope 4-10 is fixed to the center rod 4-2 through the bottom plate 4-7. When the pull rope 4-10 is pulled, the center rod 4-2 can be pulled upward, and the downward pulling force is more convenient for operation and force application.

[0036] Furthermore, the supporting moving assembly 5 includes a base frame 5-1, which is fixed to the lower end of the supporting rod 3. The outer sleeve of the base frame 5-1 is connected to a supporting seat 5-2, and the bottom of the supporting seat 5-2 is fixedly connected to a plurality of moving wheels 5-3.

[0038] Furthermore, the bracket 4-13 is an L-shaped structure as a whole, and the width of the bracket 4-13 matches the inner width of the docking groove 4-12.

[0039] In this embodiment, in order to keep the sleeve frame 4-5 in the raised state for loading and unloading the cast iron pot, a bracket 4-13 is rotated on the outside of the center frame 2, and the bracket 4-13 can be inserted into the docking groove 4-12 at the bottom of the bottom plate 4-7 to fix the raised center rod 4-2.

[0040] Furthermore, a pair of lifting hooks 6 are fixedly connected to the top of the central frame 2 .

[0041] In this embodiment, the hook is used to lift the crane through a lifting device, which is convenient for connection, and the relative spacing is large, so it is not easy to shake when hanging.

[0042] Furthermore, the cross section of the bottom cavity 4-1 is a rectangular structure.

[0043] In this embodiment, the rectangular structure allows the center rod 4-2 to move up and down while maintaining a constant vertical angle and will not rotate laterally.

[0044] When it is needed, it is moved to the processing position through the moving wheel 5-3 at the bottom of the support seat 5-2, and then connected to the hook through the lifting equipment to lift the whole structure out of the stable frame 4-9. When hanging the pot, hold the handle 4-11 and pull the pull rope 4-10 downwards. The pull rope 4-10 pulls the bottom plate 4-7 upwards so that the center rod 4-2 props up the dispersion frame 4-3. At the same time, the bracket 4-13 is pushed by the pull rod 4-14 to be inserted into the docking groove 4-12 at the bottom of the bottom plate 4-7. After keeping the height fixed after lifting, the cast iron pot is hung on the hanging rod 4-4. After all are hung, the bracket 4-13 is pulled out from the docking groove 4-12 to make the dispersion frame 4-3 fall downward, and the sleeve frame 4-5 is sleeved on the hanging rod 4-4 and kept pressed by the elastic force of the spring 4-6. Finally, it is lifted by the lifting equipment and put into the salt bath furnace for processing.
