Description

Technical Field:

[0001] The utility model relates to the technical field of rubber processing equipment, and more specifically, to a rubber sealing ring punching machine. Background Art:

[0002] Rubber sealing rings are widely used in various machinery, resistant to various petroleum-based oils and a variety of chemical media, as a sealing effect. At the same time, in order to meet different usage ranges, various modified materials are mixed in the rubber raw materials to achieve rubber sealing rings with different characteristics. For example, in a high-temperature and corrosion-resistant rubber sealing ring, fluororubber is used, which has excellent high-temperature resistance and corrosion resistance and can maintain stable performance under extreme conditions. It has good resistance to most oils, solvents, and chemicals, and is especially suitable for high-demand environments such as diesel engines, fuel systems, and chemical plants. However, fluororubber has poor cold resistance, and the general operating temperature range is -20°C to 250°C.

[0003] The processing technology of high-temperature and corrosion-resistant rubber sealing rings is generally to extrude the raw materials and place them above the lower die. Then, the upper die presses down and covers the lower die to form multiple sealing rings. Then, the upper die opens, and the formed rubber material is taken out. When taking out, the rubber sealing ring and the surrounding edge materials are adhered together to form a whole piece. Subsequently, it is necessary to manually cut the rubber ring from the edge materials, which has a large amount of manual labor and poor effect. Content of the Utility Model:

[0004] The purpose of the utility model is to overcome the deficiencies of the prior art and provide a rubber sealing ring punching machine, which can automatically punch a whole piece of formed material and separate the edge materials from the rubber sealing ring, with good effect and high efficiency.

[0020] In the embodiment, as shown in Figures 1 to 5 shown, a rubber sealing ring punching machine includes a bottom frame 10. In the middle of the top surface of the top plate of the bottom frame 10, a bottom support frame 20 is fixedly arranged. On the front and rear parts of the top surface of the top plate 25 of the bottom support frame 20, side plates 21 extending left and right are fixedly arranged. An upper horizontal support plate 22 is fixedly arranged on the top surfaces of the two side plates 21. A plurality of punching through holes 23 corresponding to the rubber sealing rings to be processed are formed on the upper horizontal support plate 22;

[0021] On the top surface of the top plate of the bottom frame 10, a main support frame 30 is fixedly arranged. The top plate of the main support frame 30 is directly above the upper horizontal support plate 22;

[0022] On the top surface of the top plate of the main support frame 30, a plurality of punching cylinders 31 are fixedly arranged. The bottom ends of the push rods of all the punching cylinders 31 extend out of the bottom ends of the corresponding through holes formed on the top plate of the main support frame 30 and are fixedly connected to the top ends of buffer springs 3. The bottom ends of the buffer springs 3 are pressed against the top surface of the lower lifting plate 32. On the outer side wall of the bottom end of the push rod of the punching cylinder 31, a radially extending edge is formed. The radially extending edge is fixedly connected to the lifting plate 32 through bolts. Among them, the distance between the radially extending edge and the lifting plate 32 is the height of the semi-compressed state of the buffer spring 3. By adopting this method, when the push rods of the plurality of punching cylinders 31 push, due to a certain time difference, it is impossible to ensure 100% synchronous pushing. At this time, through the telescopic adjustment of the corresponding buffer springs 3, the normal lifting of the lifting plate 32 can be ensured;

[0023] The bottom surface of the lifting plate 32 is fixedly connected to a punching fixing plate 33. The bottom surface of the punching fixing plate 33 is fixedly connected to an upper template 34. On the bottom surface of the upper template 34, a plurality of annular punching die protrusions 341 are fixedly arranged.

The outer side wall of the vertical guide rods 321 is closely attached to the inner side wall of the corresponding guide sleeve body 340.

[0026] Furthermore, the right side walls of the two side plates 21 are fixed with the same covering plate 24. The left side wall at the top of the covering plate 24 is fixed on the right side wall of the upper horizontal support plate 22, and the left side wall at the lower part of the covering plate 24 is fixed on the right side wall of the top plate 25 of the bottom support frame 20. The covering plate 24 covers the right end of the discharging cavity formed by the two side plates 21, the upper horizontal support plate 22 and the top plate 25. A plurality of air blowing through holes 241 arranged front and back are formed in the middle of the covering plate 24, and a plurality of air blowing connection heads 242 are fixed on the right side wall of the covering plate 24. The air blowing connection heads 242 communicate with the corresponding air blowing through holes 241. The outer ends of all the air blowing connection heads 242 are connected to the plurality of branched air outlet connection ports of the external pneumatic system through connecting pipes (the pneumatic system includes an air pump, the air pump is connected to the air inlet end of an air storage tank through a connecting pipe, the air outlet end of the air storage tank is connected to the air inlet end of a control valve through a connecting pipe, the air outlet end of the control valve is connected to the total air inlet of a collecting pipe, and the branched air outlet connection ports of the collecting pipe are connected to the corresponding air blowing connection heads 242 through connecting pipes).

[0027] Furthermore, a plurality of material pushing through holes 251 are formed in the top plate 25, and the material pushing through holes 251 are located directly below the corresponding punching through holes 23.

[0028] In the middle of the bottom surface of the top plate of the bottom frame 10, a pushing air cylinder 11 is fixed. The top end of the push rod of the pushing air cylinder 11 extends out of the top surface of the top plate of the bottom frame 10 and is fixed with a lower lifting plate 12. A lower horizontal pushing plate 13 is fixed on the top surface of the lower lifting plate 12. A plurality of vertical positioning rods 14 are fixed on the lower horizontal pushing plate 13. The vertical positioning rods 14 are inserted into the corresponding material pushing through holes 251, the top parts of the vertical positioning rods 14 are inserted into the middle parts of the corresponding punching through holes 23, and the top parts of the vertical positioning rods 14 face the middle through holes of the corresponding annular punching die convex parts 341.

[0029] Inner guide sleeves 1 are fixed on the inner side walls of the material pushing through holes 251, and the outer side walls of the vertical positioning rods 14 are closely attached to the inner side walls of the corresponding inner guide sleeves 1.

[0030] The bottom parts of the vertical positioning rods 14 are screwed into the corresponding screw-through holes on the lower horizontal pushing plate 13.

[0031] Guide plates 2 are fixed on the left side walls of the left side plates at the front and rear parts of the bottom frame 10, and the left end of the discharging cavity is located between the two guide plates 2.

[0032] During the use of this embodiment, a whole piece of molding material to be processed is placed on the top surface of the upper horizontal support plate 22. The lower part of the rubber sealing ring formed thereon is inserted into the corresponding punching-through hole 23. At the same time, the top of the vertical guide rod 321 is inserted into the lower middle part of the corresponding rubber sealing ring. After all the rubber sealing rings are installed in place, then, through the pushing of the push rods of all the stamping cylinders 31 (in this embodiment, there are two stamping cylinders 31, which are synchronously pushed. Of course, there may be a small deviation. However, since buffer springs 3 are provided between the bottom ends of the push rods of the other two stamping cylinders 31 and the lifting plate 32, this deviation can be automatically adjusted through the stretching deformation of the buffer springs 3 without affecting the lifting of the lifting plate 32), the push rods of the stamping cylinders 31 push, causing the upper template 34 to descend, so that the annular punching die protrusion 341 presses against the top surface of the corresponding rubber sealing ring and presses it down, separating it from the edge material connection, and pushing the rubber sealing ring into the middle part of the corresponding vertical guide rod 321. Then, the push rods of all the stamping cylinders 31 retract;

[0033] Then, the push rod of the pushing cylinder 11 retracts, causing the lower lifting plate 12 to descend, causing all the vertical positioning rods 14 to descend, making the top ends of the vertical positioning rods 14 lower than the top ends of the material pushing through holes 251, so that the rubber sealing rings on the vertical positioning rods 14 are on the top surface of the top plate 25. At this time, by opening the control valve of the pneumatic system, air blowing is realized, so that the air blowing through hole 241 blows out gas, blowing the rubber sealing rings on the top surface of the top plate 25 at the discharge cavity out from the left end and falling along the two guide plates 2. Generally, a receiving trough body can be placed at the lower part of the two guide plates 2 for receiving materials, which is very convenient, with high automation and good use effect.
