Description

Technical Field

[0001] The invention belongs to the technical field, and in particular relates to a quick connection and disassembly method and a quick connection device. Background Art

[0002] At present, in the metal forging industry, it is often necessary to use a multi-station die to forge a product, and each station is basically designed to be arranged side by side. In order to make the pressure center of the multi-station die at the pressure center of the press when it is working, to avoid the press from being overloaded and reducing the service life of the equipment. (such as Figure 1 , Figure 2 As shown in the figure, a driving cylinder 3 is usually installed between two columns 2 on the side of the press machine 1. The piston rod 4 of the driving cylinder 3 is connected to the lower mold plate 7 of the multi-station mold through a joint plate 5 and a screw 6. The mold change between multiple stations is realized by controlling the driving cylinder 3. Due to the large variety of products and frequent replacement of multi-station molds, when replacing the multi-station mold, the driving cylinder piston rod 4 and the lower mold plate 7 must be disassembled first, and then the driving cylinder piston rod 4 and the lower mold plate 7 are connected after the mold is replaced.

[0003] Under the existing technology, a joint plate 5 is fixed on the piston rod, connecting holes are set at the four corners of the joint plate 5, and screw holes are set at the corresponding positions of the connection of the lower template of the multi-station mold. When replacing the mold, the operator needs to drill between the two columns 2 on the side of the press, remove the screws 6 at the four corners of the joint plate 5, retract the piston rod 4, move the workbench of the press 1 longitudinally, and use the crane to complete the mold change. After the mold change is completed, the workbench of the press 1 moves back to the working position, and the oil cylinder 3 is driven to extend the piston rod 4 to make the joint plate 5 contact with the lower template 7. The operator drills between the two columns on the side of the press again to tighten the four bolts.

[0004] The disadvantage is that the distance between the two columns 2 on the side of the press is about 900mm. Because the driving cylinder 3 is installed between the two columns 2 on the side of the press, on the one hand, the operating space for the operator to disassemble and assemble the joint plate 5 and the screws 6 is less than 400mm, and the disassembly and assembly conditions are very poor. On the other hand, the joint plate 5 is fixed to the driving cylinder piston rod, and the screws 6 at the four corners are very close to the piston rod 4. When tightening or loosening, the wrench can only rotate 1 / 3 of a circle, and the screws 6 are arranged horizontally, which makes the operator time-consuming and laborious during construction. It takes about 10-15 minutes to tighten or loosen the screws after changing the mold, which is very inefficient. In order to solve the above problems, it is necessary to design a set of connection devices that can be quickly connected and easy to operate, so that the driving cylinder piston rod 4 and the lower template 7 can be disassembled and assembled conveniently and efficiently, reducing the construction difficulty of the operator and improving the clamping efficiency.

After the cover plate 7 is installed in the connection base 6, the upper end surface of the cover plate 7 is flush with the upper end surface of the connection base 6, and an annular groove is formed between the outer circumference of the cover plate 7 and the inner circumference of the connection base 6; the rotating disk 8 is installed in the annular groove.

[0078] (like Figure 7 ) The diameter of the rotating disk countersunk hole 803 is equal to the diameter of the locking hole 601 and the release hole 602 and is inserted and adapted with the rotating handle 10. So that the rotating handle 10 can be inserted into the locking hole 601 or the release hole 602 to lock the rotation limit position of the rotating disk 8, thereby hard locking the locking state or the release state of the locking assembly 2.

[0079] (like Fig.11 In the above embodiment, further: the locking head 9 includes a horizontal rod 901 and a vertical rod 902 which are vertically fixedly connected as one.

[0080] The front end of the horizontal rod 901 is a hemispherical cylindrical structure 903 with an increased diameter. The hemispherical cylindrical structure 903 is used to fit into the locking groove 5 of the connector or to exit the locking groove 5.

[0081] The rear end of the horizontal rod 901 is vertically fixedly connected to the bottom of the vertical rod 902; a compression spring 11 is installed between the bottom of the vertical rod 902 and the locking end of the hemispherical cylindrical structure 903; the problem of the hemispherical cylindrical structure 903 of the locking head 9 quickly and elastically snapping into the locking groove 5 is solved, and the problem of quickly finding the locking position is solved. The user can know whether the locking position has been reached by listening to the sound and feeling the touch, thereby achieving quick locking.

[0082] The top end of the vertical rod 902 is vertically inserted into the arc guide groove 801 of the rotating disk 8; when the rotating disk 8 rotates, the limit positions of the arc guide groove 801 are used to drive the locking head 9 to telescopically move, and the top end of the vertical rod 902 of the locking head 9 slides along the starting point and end point of the arc guide groove 801; the horizontal rod 901 of the locking head 9 telescopically moves along the cylindrical through groove 607, so that the locking head 9 is engaged with or exits the locking groove 5.

[0083] (like Fig.12 As shown in the above embodiment, further: the rotating handle 10 is a cylindrical rod structure, and a large-diameter cap body 1001 is formed on the outer top end; the outer diameter of the rotating handle 10 is gap-matched with the rotating disk countersunk hole 803 formed on the rotating disk 8 and is used to insert the rotating disk 8 and then drive the rotating disk 8 to rotate; the rotating handle 10 is gap-matched with the locking hole 601 and the releasing hole 602 formed on the connecting base 6; the rotating handle 10 is used to insert the locking hole 601 or the releasing hole 602 to lock the rotation limit position of the rotating disk 8 by hard blocking.

[0085] During installation: the spring 11 is installed on the horizontal rod 901 of the locking head 9 and is pre-buried in the cylindrical through groove 607 formed by the cover plate 7 and the connecting base 6.

The connector 1 moves along the inner diameter of the cover plate 7 and the connecting base 6 to the locking position (such as Figure 6 ).

[0086] When locking: turn the rotating handle 10, the rotating handle 10 drives the rotating disk 8 to rotate along the outer diameter of the cover plate 7, the arc-shaped guide groove 801 on the rotating disk 8 acts a radial force on the vertical rod 902 of the locking head 9, and the vertical rod 902 drives the locking head 9 as a whole to extend and move along the cylindrical through groove 607 formed by the cover plate 7 and the connecting base 6; when the rotating handle 10 is rotated to the locking position, the vertical rod 902 moves to the extreme end locking position of the arc-shaped guide groove 801, and the hemispherical cylindrical structure 903 at the front end of the locking head 9 completely extends out of the cylindrical through groove 607 of the cover plate 7 and the connecting base 6, reaches the locking position and is stuck in 5; at the same time, the rotating handle 10 is axially inserted into the locking hole 601 on the connecting base 6 to complete the locking of the quick connection device.

[0087] (like Figure 5When disassembling as shown in the figure: pull the rotating handle 10 out of the locking hole 601 on the connecting base 6 along the axial direction, rotate the rotating disk 8 in the reverse direction, the arc-shaped guide groove 801 on the rotating disk 8 acts a radial force on the vertical rod 902 of the locking head 9, and the vertical rod 902 drives the locking head 9 as a whole to move back along the radial cylindrical through groove 607; when the rotating handle 10 is rotated to the release position, the vertical rod 902 just moves to the outermost release position of the arc-shaped guide groove 801, and the hemispherical cylindrical structure 903 at the front end of the locking head 9 is completely retracted into the cover plate 7 and the cylindrical through groove 607 of the connecting base 6. At this time, the rotating handle 10 is further inserted into the release hole 602 at the release position on the connecting base 6 along the axial downward direction, so that the connecting device is in a release state, and the connecting head 1 is removed at this time to complete the disassembly work.
