This type of top hammer usually has six faces, which can press and hammer the workpiece at different angles and directions, thereby achieving multi-faceted processing and forming.

[0003] After a certain period of use, the top hammer of the six-sided top press needs to be dismantled and repaired or maintained regularly due to severe wear. The existing top hammer of the top press is generally fixedly connected to the hydraulic cylinder connector with multiple high-strength metal bolts and nuts. When disassembling, it is necessary to use professional tools to remove them one by one to release the fixing effect of the top hammer, which makes the disassembly process of the top hammer cumbersome and inconvenient, and also affects the work efficiency of the staff. In order to solve the above problems, another top hammer of the six-sided top press is provided. Utility Model Content

DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] See also Figure 1-Figure 4 , the utility model provides a technical solution:

[0021] A six-sided top hammer of a top press comprises a T-shaped connector 1 and a top hammer body 2. The lower surface of the T-shaped connector 1 is provided with an installation cavity 11. The top hammer body 2 is installed in the installation cavity 11. The lower surface of the T-shaped connector 1 is symmetrically provided with two slots A111 connected to the installation cavity 11. The slots A111 are circumferentially provided with slideways 112 connected to the installation cavity 11. The outer surface of the top hammer body 2 is symmetrically fixed with sliders 21. The sliders 21 are inserted into the slots A111 and then slidably arranged on the corresponding slideways. The lower surface of the slider 21 is penetrated with a locking hole 211, the lower end of the T-shaped connector 1 is slidably mounted with an annular support shell 3, the lower surface of the annular support shell 3 is symmetrically penetrated with a slot B31, the slot B31 is located directly below the slot A111, and a locking rod 32 is symmetrically fixedly installed in the annular support shell 3, the locking rod 32 penetrates the lower surface of the T-shaped connector 1 and is plugged into the locking hole 211, and a plurality of tightening springs 141 are fixedly installed between the annular support shell 3 and the T-shaped connector 1;

[0022] The T-shaped connector 1 is used to connect with the telescopic cylinder that drives the top hammer to move on the six-sided top press;

[0023] The tightening spring 141 is used to pull the annular support shell 3, keep the locking rod 32 in the locking hole 211, and move the slider 21 to be fixed in the slideway 112;

[0024] When the top hammer body 2 and the T-shaped connecting piece 1 are separated for repair or maintenance, the annular support shell 3 is pulled downward by external force to drive the locking rod 32 to disengage the locking hole 211 of the slider 21, and the fixation of the slider 21 can be released. After that, the top hammer body 2 is rotated, and the slider 21 is rotated to the corresponding slot A111, and the top hammer body 2 is moved downward to be separated from the T-shaped connecting piece 1. During the whole operation process, there is no need to separate multiple bolts and nuts. It is only necessary to move the annular support shell 3 downward, rotate the top hammer body 2, and then move it downward to separate it. Compared with the prior art, the disassembly operation is simple and convenient, which can improve the disassembly efficiency of the staff;

[0025] When the top hammer body 2 and the T-shaped connector 1 are installed together, the operation is performed in the reverse direction, and the slider 21 of the top hammer body 2 passes through the slot B31 and the slot A111 and enters the slideway 112. Then, the annular support shell 3 is pulled down by an external traction device to make the locking rod 32 disengage from the slideway 112, and then the top hammer body 2 is rotated to make the slider 21 slide to the end of the corresponding slideway 112. At this time, the downward pulling force on the annular support shell 3 is released. Under the action of the tightening spring 141, the annular support shell 3 drives the locking rod 32 to move up and reset. The locking rod 32 is inserted into the locking hole 211 of the slider 21, thereby fixing the top hammer body 2 in the installation cavity 11 of the T-shaped connector 1. The upper end outer surface of the top hammer body 2 after installation is in contact with the inner side wall of the installation cavity 11, and the lower end outer surface is in contact with the inner side wall of the annular support shell 3.

[0026] It should be noted that if Figure 5 As shown, the lower surface of the T-shaped connector 1 is provided with a plurality of recessed holes 14 equidistantly in the circumferential direction, the top end of the tightening spring 141 is fixedly installed in the corresponding recessed hole 14, and the bottom end of the tightening spring 141 is fixedly connected to the annular support shell 3. The tightening spring 141 can be "hidden" in the T-shaped connector 1 by being installed in the recessed hole 14. It is shielded by the annular support shell 3 and is not easy to come into contact with foreign objects during use, thereby ensuring the use effect.

[0027] It is worth noting that when the top hammer body 2 is subjected to external force and wants to rotate, the slider 21 is used to pull the locking rod 32 to apply force. In order to prevent the locking rod 32 from bending under force and affecting the disassembly of the top hammer body 2, Figure 2 As shown, an arc-shaped positioning rod 12 with a through hole 121 is fixedly installed at one end of the slideway 112 away from the slot A111. Figure 4 As shown, an arc-shaped hole 212 is formed on one side of the slider 21 opposite to the arc-shaped positioning rod 12. When the slider 21 slides to the end of the slideway 112, the arc-shaped positioning rod 12 is inserted into the corresponding arc-shaped hole 212. The locking rod 32 is inserted into the through hole 121 of the arc-shaped positioning rod 12. The arc-shaped positioning rod 12 can be used to share the traction force on the locking rod 32, thereby preventing the locking rod 32 from bending under force and affecting the disassembly of the top hammer body 2. The locking rod 32 and the arc-shaped positioning rod 12 are both made of alloy steel.

[0028] In addition, when installing the top hammer body 2, in order to ensure that the locking rod 32 can move up and down, the T-shaped connector 1 is accurately inserted into the locking hole 211 of the slider 21, such as Figure 3 As shown, the inner side wall of the annular support shell 3 is symmetrically provided with sliding grooves 33. Figure 2 As shown, the outer surface of the T-shaped connector 1 is symmetrically fixed with positioning ribs 13. After the positioning ribs 13 are slidably connected with the slide groove 33, the annular support shell 3 can drive the locking rod 32 to move vertically up and down, so that the locking rod 32 can be accurately inserted into the locking hole 211 of the slider 21.

[0029] Finally, in order to facilitate the use of external equipment to pull the annular support shell 3, such as Figure 3 As shown, an L-shaped ear block 34 is symmetrically fixedly installed on the outer surface of the annular support shell 3. An external hook can be used to hang on the L-shaped ear block 34, and then an external traction device is used to cooperate with an external wire rope to pull the external hook to pull the annular support shell 3, so as to pull the locking rod 32 away from the locking hole 211 of the slider 21 to contact and fix the top hammer body 2.
