[0020] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0021] Please refer to Figures 1-5 , a front and rear hydraulic cylinder structure of a multi-directional die forging hydraulic press with adjustable eccentricity, including a die backing plate 1. A placing groove 14 is opened at the top of the die backing plate 1. A male and female key 3 is provided on the inner wall of the placing groove 14. The top of the male and female key 3 is fixedly connected to a frame column 2. A first movable groove 7 and a first installation groove 9 are respectively opened in the middle of the die backing plate 1. A movable block 6 is slidably connected to the inner wall of the first movable groove 7. A connecting rod 5 is fixedly assembled on the side of the movable block 6 away from the first installation groove 9. The end of the connecting rod 5 is fixedly assembled with an extrusion rod 4. A first retaining ring 10 is sleeved on the inner wall of the first installation groove 9. A first retaining pin 11 abuts against the outer wall of the first retaining ring 10. A circular groove 8 is opened on the outer wall of the male and female key 3. A second installation groove 16 is opened in the middle of the male and female key 3. A second retaining ring 15 is sleeved on the inner wall of the second installation groove 16. A second retaining pin 12 abuts against the outer wall of the second retaining ring 15. One end of the second retaining pin 12 away from the second retaining ring 15 abuts against a push rod 13. A round rod 17 is fixedly assembled at one end of the second retaining pin 12 close to the second retaining ring 15.

[0022] In the above structure, through the structure of the die backing plate 1, the frame column 2, and the male and female key 3, the hydraulic press can adjust the eccentricity distance of the front and rear cylinders by adjusting the size and dimensions of the male and female key 3 during the operation process, so that the hydraulic press can forge and form parts with complex structures, improve the material utilization rate, reduce the mechanical processing time, and lower the production cost.

[0023] In a preferred embodiment: One end of the push rod 13 close to the movable block 6 is fixedly assembled with the outer wall of the movable block 6. The inner wall of the circular groove 8 is slidably connected to the outer wall of the push rod 13, and the outer wall of the round rod 17 is also slidably connected to the inner wall of the circular groove 8.

[0024] In the above structure, through the circular groove 8 and the circular rod 17 structures provided, when the user installs the male-female key 3, the male-female key 3 can be docked with the placement groove 14 by means of the second pin 12. Therefore, after the male-female key 3 is installed, the second pin 12 can make the male-female key 3 fixedly connected to the placement groove 14 through the elasticity of the second retaining spring 15, thereby achieving the effect of quickly installing the male-female key 3, and further improving the adjustment efficiency of the user for the mold.

[0025] In a preferred embodiment: The male-female key 3 is fixedly connected to the mold backing plate 1 through the second pin 12 and the circular rod 17, and the outer wall of the connecting rod 5 is slidably connected to the inner wall of the circular groove 8.

[0026] In the above structure, through the circular groove 8 structure provided, when the user presses the extrusion rod 4, the second pin 12 is extruded by the push rod 13 to disengage from the through hole, so that the second pin 12 moves. Subsequently, the movement of the second pin 12 presses the first pin 11 to disengage from the circular groove 8 through the circular rod 17. At this time, the male-female key 3 is movably connected to the mold backing plate 1, thus facilitating the user to disassemble the male-female key 3, and further achieving the effect of quickly disassembling and assembling the male-female key 3, which is convenient for the user to adjust the mold.

[0027] In a preferred embodiment: The number of the placement grooves 14 is two, and the two placement grooves 14 are symmetrically distributed along the top of the mold backing plate 1.

[0028] In the above structure, through the two placement groove 14 structures provided, the user can fix the body column 2 through the two male-female keys 3, so that both hydraulic cylinders can be fixed, which is convenient for the user to process parts from both sides, and further ensures the normal use of the hydraulic cylinder.

[0029] In a preferred embodiment: One end of the circular rod 17 away from the second pin 12 abuts against the outer wall of the first pin 11. A through hole is formed in the inner wall of the first movable groove 7, and the length of one end of the second pin 12 located on the inner wall of the through hole is adapted to the length of one end of the first pin 11 located on the inner wall of the circular groove 8.

[0030] In the above structure, through the through hole, the first movable groove 7 and the first pin 11 structures provided, both sides of the male-female key 3 are fixed respectively due to the connection between the second pin 12 and the through hole and the insertion of the first pin 11 into the circular groove 8, thereby ensuring that the male-female key 3 will not shake or even shift in position after installation, and further improving the stability of the hydraulic press during operation.

[0031] In a preferred embodiment: The length of the second installation groove 16 is adapted to the length of one end of the second pin 12 displaced on the inner wall of the through hole. The connecting rod 5, the push rod 13, the second pin 12, the circular rod 17 and the first pin 11 are all made of galvanized iron metal.

[0032] In the above structure, the galvanized iron metal has the characteristics of hardness and wear resistance, which can effectively reduce the wear of the five components during movement, thus ensuring the fixing effect on the male-female key 3, while prolonging the service life of the five components, further reducing the maintenance frequency of the hydraulic press, and also reducing the maintenance cost of the hydraulic press.

[0033] Working principle: First, the user picks up the male-female key 3, and then presses the second pin 12 and the first pin 11, so that the second pin 12 and the first pin 11 both contract, allowing the male-female key 3 to be docked with the placement groove 14. The male-female key 3 is fixedly connected to the die backing plate 1 under the connection action of the second pin 12 and the first pin 11. During the operation of the hydraulic cylinder, the male-female key 3 cannot be displaced. After processing a single specification of parts, the user can press the extrusion rod 4 to move the second pin 12, driving the round rod 17 to move, thereby squeezing the first pin 11 out of the round groove 8. At the same time, the second pin 12 will disengage from the through hole, so that the male-female key 3 is movably connected to the die backing plate 1. Then the user can take out the male-female key 3 and reinstall the second male-female key 3 to achieve the effect of quickly replacing male-female keys 3 of different specifications to process different parts, thereby improving the usage range of the hydraulic cylinder and the working efficiency of the user.

[0034] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
