[0026] A multi-station die-free round steel blanking die, such as Figure 1 and Figure 2 Shown, including:

[0027] The lower seat 10 and the upper seat 11, the upper seat 11 is arranged above the lower seat 10 and is elastically connected to the upper seat 11, the top surface of the lower seat 10 is fixedly installed with a cutting table 12, and the bottom of the blade 13 is fixedly installed with a blade 13. Specifically, the lower seat 10 needs to be fixedly mounted on the frame for use, and a cylinder should be installed on the frame. The upper seat 11 is fixedly connected to the output shaft of the cylinder, and the upper seat 11 is pushed down and close to the lower seat 10 by the cylinder, so that the blade 13 moves down to cooperate with the cutting table 12 to cut the round steel. I will not go into details here.

[0028] like Figure 2 、 Figure 3 、 Figure 4 and Figure 5As shown, the clamping structure is arranged at the bottom of the upper seat 11 for clamping the raw material. The clamping structure includes a clamping groove 20, a contact plate 21, a connecting plate 22 and a sliding channel 23. The connecting plate 22 is fixedly connected to the upper seat 11. The connecting plate 22 opens a sliding channel 23. The sliding block 24 is located in the sliding channel 23 and is elastically connected to the connecting plate 22. The contact plate 21 is fixedly connected to the sliding block 24. The contact plate 21 is located directly above the cutting table 12. The contact plate 21 and the cutting table 12 contact surface jointly open a number of clamping grooves 20 with different diameters. The clamping structure also includes a reset spring 25. The reset spring 25 The sliding channel 23 is provided, and the return spring 25 can push the sliding block 24 downward. The connecting plate 22 forms a rectangular block structure. The sliding channel 23 is provided at the bottom of the connecting plate 22. The sliding block 24 is a rectangular block. The sliding channel 23 and the sliding block 24 cooperate with each other. The two ends of the return spring 25 are fixedly connected to the sliding block 24 and the connecting plate 22 respectively. A notch is provided on the top of the cutting table 12, and the contact plate 21 can be inserted into the notch. A plurality of semicircular grooves are provided on the top surface of the cutting table 12 and the bottom of the contact plate 21. The two semicircular grooves symmetrically formed on the upper and lower sides form a clamping groove 20.

[0029] In this solution, in order to solve the problem that the closed clamping groove 20 is inconvenient for placing round steel, an upwardly movable contact plate 21 is provided. The contact plate 21 and the cutting table 12 jointly open the clamping groove 20. When the contact plate 21 moves upward, the clamping groove 20 is in an open state, so that the round steel can be conveniently placed in the half clamping groove 20 at the top of the cutting table 12. As the contact plate 21 descends, the clamping groove 20 closes and clamps the round steel to a limited position, which is convenient for loading and unloading.

[0030] By fixing the connecting plate 22 to the upper seat 11, when the upper seat 11 moves downward, the upper seat 11 pushes the connecting plate 22 to move downward, and the contact plate 21 gradually contacts the top of the cutting table 12. The cutting table 12 pushes the sliding block 24 to slide in the sliding channel 23 and squeezes the return spring 25 to deform, thereby realizing the elastic connection of the contact plate 21. The contact plate 21 can contact the cutting table 12 to close the clamping groove 20, and at the same time, it can prevent the contact plate 21 from squeezing the cutting table 12 too much to form grooves on the surface of the round steel. When the blade 13 descends to cut the round steel, the round steel is not easy to slip, and the cutting accuracy is guaranteed. On the basis of ensuring a good clamping effect on the round steel, the integrity of the round steel is guaranteed, and at the same time, the cutting table 12 and the contact plate 21 can be protected.

[0031] like Figure 1 and Figure 2 As shown, the reset structure is provided on the top of the lower seat 10 for supporting and limiting the upper seat 11;

[0032] The reset structure includes guide rods 14, guide cylinders 15, and springs 16. Two guide rods 14 are fixedly mounted on the top of the lower seat 10, and two guide cylinders 15 are fixedly mounted on the bottom of the upper seat 11. The guide rods 14 are slidably connected to the corresponding guide cylinders 15. The springs 16 are sleeved on the walls of the guide rods 14, and the ends of the springs 16 abut against the ends of the guide cylinders 15. A vertical slot is opened on the top of the cutting table 12, and the blade 13 slides in the vertical slot.

[0033] In this solution, the vertical reciprocating motion stability of the upper seat 11 is solved by cooperating with the cylindrical guide rod 14 and the tubular guide cylinder 15. The guide rod 14 is slidably set in the cavity of the guide cylinder 15, so that the upper seat 11 can maintain vertical displacement. The guide rod 14 can push the guide cylinder 15 to separate the upper seat 11 from the lower seat 10, thereby promoting the upward movement and reset of the upper seat 11.

[0034] The working principle of the present invention is as follows: when the contact plate 21 moves upward, the clamping groove 20 is in an open state, and the round steel can be easily placed in the half clamping groove 20 on the top of the cutting table 12. As the contact plate 21 descends, the clamping groove 20 closes to clamp the round steel and limit the position, fixing the connecting plate 22 to the upper seat 11. When the upper seat 11 moves downward, the upper seat 11 pushes the connecting plate 22 down, and the contact plate 21 gradually contacts the top of the cutting table 12. The cutting table 12 pushes the sliding block 24 in the sliding channel 23. The return spring 25 slides inward and squeezes the deformation, realizing the elastic connection of the contact plate 21. The contact plate 21 can contact the cutting table 12 to close the clamping groove 20. At the same time, it can prevent the contact plate 21 from squeezing the cutting table 12 too hard and causing grooves on the surface of the round steel. When the blade 13 descends to cut the round steel, the round steel is not easy to slip. The cylindrical guide rod 14 and the tubular guide cylinder 15 cooperate with each other. The guide rod 14 is slidably set in the cavity of the guide cylinder 15, so that the upper seat 11 can maintain vertical displacement.

[0035] Among them, in order to realize multi-station unloading, several groups of lower seats 10 and upper seats 11 are set on the frame, thereby achieving the purpose of multi-station simultaneous operation, which will not be described in detail here.
