DETAILED DESCRIPTION

[0025] like Figure 1-2 As shown, a double-sided extrusion frame-type hydraulic press for processing automobile sleeves includes a frame 1, which is fixed to a frame. A lower clamp assembly 2 is provided at the lower end of the frame 1, and an upper clamp assembly 3 is provided at the upper end. The upper clamp assembly 3 is driven up and down by a first hydraulic cylinder 4. The upper clamp assembly 3 is driven downward by the first hydraulic cylinder 4 and cooperates with the lower clamp assembly 2 to complete the clamping of the automobile sleeve 7. The left end of the frame 1 is provided with a first die assembly 5, and the right end is provided with a second die assembly 6. The first die assembly 5 and the second die assembly 6 are directly opposite to the automobile sleeve 7 on the lower clamp assembly 2. Among them, the first die assembly 5 is driven to extend and retract horizontally by the second hydraulic cylinder 8, and the second die assembly 6 is driven to extend and retract horizontally by the third hydraulic cylinder 9. By extending the first die assembly 5 and the second die assembly 6 at the same time, the left and right end holes of the automobile sleeve 7 can be punched axially.

[0026] like Figure 3As shown, the lower clamp assembly 2 includes a lower clamp plate 2.1, which has an arc-shaped groove, and the arc-shaped groove matches the outer diameter of the automobile sleeve 7 to be processed. The lower end of the lower clamp plate 2.1 can be detachably mounted on the first adjustment mechanism; the upper clamp assembly 3 includes an upper clamp plate 3.1, which has an arc-shaped groove, and the arc-shaped groove matches the outer diameter of the automobile sleeve 7 to be processed. The upper end of the upper clamp plate 3.1 can be detachably mounted on the second adjustment mechanism. By setting the first adjustment mechanism and the second adjustment mechanism, the installation position of the automobile sleeve 7 can be precisely adjusted to ensure processing accuracy. By setting the arc-shaped grooves on the upper clamp plate 3.1 and the lower clamp plate 2.1, when the upper clamp plate 3.1 and the lower clamp plate 2.1 are closed, the upper clamp plate 3.1 and the lower clamp plate 2.1 firmly clamp the automobile sleeve 7.

[0027] like Figure 3-4 As shown, the first and second adjustment mechanisms have identical structures, each comprising a first mounting plate 2.2. The upper end of the first mounting plate 2.2 is provided with a first locating slot, the length and width of which match those of the lower clamping plate 2.1 or upper clamping plate 3.1. The lower clamping plate 2.1 or upper clamping plate 3.1 is placed in the first locating slot and secured with screws. This facilitates the replacement of different lower clamping plates 2.1 and upper clamping plates 3.1 according to the specifications of the vehicle sleeve 7. The lower end of the first mounting plate 2.2 is placed in the second locating slot of the second mounting plate 2.3 and secured with screws at both ends. The second mounting plate 2.3 is placed in a groove of the third mounting plate 2.4, which has a rectangular cross-section and is slightly larger in length and width than the second mounting plate 2.3. The third mounting plate 2.4 has first threaded holes 2.5 horizontally formed on the left and right sides, and second threaded holes 2.6 horizontally formed on the front and back sides. Screws are installed in the corresponding first and second threaded holes 2.5 and 2.6. After the screw is screwed in, the second mounting plate 2.3 can be adjusted for forward and backward movement and left and right movement. Furthermore, adjustment holes 2.7 are vertically provided on the second mounting plate 2.3. These holes 2.7 are aligned with third threaded holes 2.8 on the third mounting plate 2.4. The length and width of adjustment holes 2.7 are larger than the diameter of third threaded holes 2.8. After the second mounting plate 2.3 is adjusted to its proper position, the screw with the larger head is passed through adjustment holes 2.7 and screwed into third threaded holes 2.8 before being tightened, thereby restricting the vertical movement of the second mounting plate 2.3. This completes the fixation.

[0028] like Figure 5-7 As shown, the first die assembly 5 includes a first die 5.1, the end of which is a hexagonal prism that matches the end hole of one end of the automobile sleeve 7. The second die assembly 6 includes a second die 6.1, the end of which is a quadrangular prism that matches the end hole of the other end of the automobile sleeve 7. The first die 5.1 and the second die 6.1 punch the end holes along the axial direction at both ends of the automobile sleeve 7. The first die 5.1 and the second die 6.1 are each secured by a set of locking mechanisms 10.

[0029] like Figure 5 As shown, the locking mechanism 10 includes a limit seat 10.1. The limit seat 10.1 is a cap structure with an open side and a flange on the edge. The limit seat 10.1 is removably fixed to the mounting seat 10.2 via the flange and bolts. The mounting seat 10.2 is fixed to the output end of the corresponding second hydraulic cylinder 8 or third hydraulic cylinder 9. The other end surface of the limit seat 10.1 is provided with a through hole 10.3. The diameter of the through hole 10.3 is larger than the main body of the first die head 5.1 or the second die head 6.1, and the diameter of the through hole 10.3 is smaller than the diameter of the limit ring 10.4 (when the second gasket 10.6 is present, the diameter of the through hole 10.3 can be larger than the diameter of the limit ring 10.4). The limit ring 10.4 is placed in the limit seat 10.1 and is limited in its movement along the axial direction; the other end of the first die head 5.1 or the second die head 6.1 extends out of the through hole 10.3. One end of the limiting ring 10.4 can contact the end surface of the mounting seat 10.2 and the other end can contact the inner top surface of the limiting seat 10.1 away from the mounting seat 10.2. In this way, after the limiting seat 10.1 is installed, the first die head 5.1 or the second die head 6.1 is fixed.

[0030] Preferably, a first gasket 10.5 and a second gasket 10.6 are respectively disposed within the limiting seat 10.1, located to the left and right of the limiting ring 10.4. The first gasket 10.5 is located on one side of the mounting seat 10.2, while the second gasket 10.6 is located away from the mounting seat 10.2. A mounting hole 10.7 is defined in the center of the first gasket 10.5. A spring 10.8 is disposed within the mounting hole 10.7. The spring 10.8 is compressed, with one end of the spring 10.8 resting on the first die 5.1 or the second die 6.1 and the other end resting on the mounting seat 10.2. The spring 10.8 has a high elastic modulus. Even when the first gasket 10.5 or the second gasket 10.6 is squeezed and deformed, the spring 10.8 can still provide a sufficient thrust to maintain the first die 5.1 or the second die 6.1 in its outward direction.

[0031] Working principle and process:

[0032] 1) First, place the automobile sleeve 7 on the lower clamping plate 2.1, and the automobile sleeve 7 is in a horizontal state.

[0033] 2) Then, the first hydraulic cylinder 4 is started, and the first hydraulic cylinder 4 drives the upper clamp assembly 3 to move downward, and the lower clamping plate 2.1 and the upper clamping plate 3.1 act together on the side wall of the automobile sleeve 7 to clamp the automobile sleeve 7.

[0034] 3) Subsequently, the second hydraulic cylinder 8 and the third hydraulic cylinder 9 extend, and the first die head 5.1 and the second die head 6.1 punch holes at both ends of the automobile sleeve 7.

[0035] 4) Finally, the first hydraulic cylinder 4, the second hydraulic cylinder 8, and the third hydraulic cylinder 9 are reset, the punched automobile sleeves 7 are removed, and the punching operation of the next group of automobile sleeves 7 is carried out.
