The top of the lower pressing block 20 is inserted into the mounting groove 471 of the lower pressing rod 47, the mounting groove 471 penetrates through the lower pressing rod 47 from front to back, the second rotating shaft 472 penetrates through the mounting groove 471 of the lower pressing rod 47 from left to right, and the lower pressing block 20 is fixed in the mounting groove 471, so that the lower pressing block 20 can rotate back and forth along the axis of the second rotating shaft 472. As shown in fig. 5, the top of the lower pressing block 20 is further provided with a locking hole 28 extending to a connecting hole through which the second rotating shaft 472 can pass, and the locking member can be inserted into the locking hole 28 to abut against the second rotating shaft 472, so as to limit the forward and backward rotation of the lower pressing block 20 relative to the second rotating shaft 472, and the lower pressing block 20 is limited in the mounting groove 471, so that the lower pressing block 20 and the lower pressing rod 47 can be fixedly connected through the locking hole 28.

The working process of the extrusion device 100 provided by the invention comprises the following steps:

firstly, the product 90 is placed on the two second tungsten steel sleeves 14 of the supporting assembly 10, the second driving assembly 13 is turned on, and the two supporting shafts 12 drive the second tungsten steel sleeves 14 to synchronously rotate, so as to drive the product 90 to rotate on the supporting assembly 10 along the axis of the product 90.

Then, the first driving assembly 30 is started to drive the lower pressing block 20 and the lower pressing assembly 40 on the first sliding block 33 to synchronously move downwards until the first tungsten steel sleeve 23 at the bottom of the lower pressing block 20 abuts against the rotating product 90, and the first driving assembly 30 continuously drives the first sliding block 33 to move downwards, so that the lower pressing block 20 and the second sliding block 43 move upwards along the linear guide rail 42 to press the lower pressing spring 44 in the lower pressing assembly 40.

Then, the position sensor 48 in the pressing assembly 40 detects that the sensing piece 49 moves upward along with the second slider 43, and at this time, the first tungsten steel sleeve 23 of the pressing block 20 contacts the product 90, and the first driving motor 31 stops driving downward, and at the same time, the driving cylinder 46 is turned on. The driving rod 461 of the driving cylinder 46 moves the upper end 451 of the lever 45 away from the first slider 33, and the lower end 452 of the lever 25 moves toward the first slider 33, pushing the lower pressing rod 47 to abut against the horizontal supporting plate 41, i.e. the lower pressing block 20 fixed to the lower pressing rod 47 and the second slider 43 are fixed to the first slider 33, so that the lower pressing block 20 and the first slider 33 are fixed together.

Finally, when the lower pressing block 20 and the first sliding block 33 are fixed into a whole, the first driving motor 31 drives the first sliding block 33 to move downwards again, and drives the lower pressing block 20 to extrude the product 90 downwards, so that the downward movement amount of the first driving motor 31 is the pushing amount of the lower pressing block 20 to extrude the product 90.

The extrusion device 100 provided by the invention drives the lower pressing block 20 to move towards the product 90 on the supporting component 10 through the first driving component 30, so as to realize extrusion on the product 90; the supporting assembly 10 is used for driving the product 90 to rotate along the axis of the product 90, the rolling extrusion on the product 90 is realized by matching with the lower pressing block 20, and the force born by the lower pressing block 20 when the product 90 is extruded by the lower pressing block 20 is transmitted to the bearing 24; briquetting 20 and first drive assembly 30 are between through pushing down subassembly 40 elastic connection, earlier through this pushing down subassembly 40 will push down briquetting 20 butt to product 90 on, make this pushing down briquetting 20 and bearing assembly 10 between the relative position can be applicable to not unidimensional product 90 extrusion and use, briquetting 20 downshifting is driven to rethread first drive assembly 30, carry out the accurate extrusion to product 90, thereby guarantee to the extruded size precision of product 90, realize the accurate extrusion to product 90.
