It is a spring buffer device for a medium plate turning machine in medium plate production, and is used to buffer the contact between a stainless steel plate and a stop block of the frame of the medium plate turning machine when the medium plate turning machine performs the turning operation. Background Art

[0002] When the medium plate turning machine performs the turning operation, as the lifting angle of the frame of the medium plate turning machine increases, the stainless steel plate slides on the frame of the medium plate turning machine under the action of gravity, and thus collides with the bottom stop block of the frame. Due to the large weight of the steel plate itself, the steel plate after collision will have problems such as deformation, scratching, notches, flanging, burrs, etc., which greatly affect the quality of the finished steel plate. At the same time, the collision also causes great damage to the service life of the stop block of the frame of the medium plate turning machine.

[0016] The following further details the present utility model in conjunction with the drawings and through embodiments. The following embodiments are explanations of the present utility model and the present utility model is not limited to the following embodiments.

[0017] Embodiment

[0018] Refer to Figures 1 to 3 , in this embodiment, the plate turning machine spring buffer device includes lead screw 1, nut 2, box body 5, spring 6, sleeve 7, round steel bar 8, perforated plate 9, and buffer block 10. The nut 2 is located on the lead screw 1, the lead screw 1 is connected to the buffer block 10, the spring 6 is located inside the box body 5, the sleeve 7 is located inside the spring 6 and is connected to the buffer block 10, the perforated plate 9 is fixed to the upper and lower sides of the box body 5, the holes in the middle position of the perforated plate 9 cooperate with the round steel bar 8, and the round steel bar 8 is connected to the buffer block 10.

[0019] The lead screw 1 in this embodiment is located at the bottom of the device and is directly welded to the buffer block 10, and can act together with the nut 2 to adjust the length of the buffer block 10 protruding from the device.

[0020] In this embodiment, there are two nuts 2. The two nuts 2 are located on the lead screw 1. One is an adjusting nut 2 for adjusting the protruding length of the buffer block 10, and the other is a locking nut 2 for locking the device after the length adjustment to prevent the protruding length of the buffer block 10 from changing during operation.

[0021] The stainless steel pad 3 in this embodiment is located at the bottom of the box body 5, and plays a role of buffering and decompressing between the box body 5 and the nut 2, and is used to protect the box body 5.

[0022] The box body reinforcement plate 4 in this embodiment is located at the bottom of the box body 5, bears the elastic force after the spring 6 is compressed, and protects the device from deformation.

[0023] The box body 5 in this embodiment is the main body of the buffer device housing.

[0024] The spring 6 in this embodiment is located inside the box body 5, and is used to absorb the impact kinetic energy of the steel plate, reduce the contact speed between the steel plate and the stopper of the middle plate turning machine frame, and play a buffering role.

[0025] The sleeve 7 in this embodiment is located inside the spring 6 and is welded to the buffer block 10. When the spring 6 is compressed by force, it regularizes the movement trajectory of the spring 6 and prevents the spring 6 from skewing, thereby stabilizing the movement direction of the buffer block 10.

[0026] In this embodiment, there are two upper and lower round steel bars 8. The two upper and lower round steel bars 8 are located in the central hole of the perforated plate 9 and are welded to the buffer block 10, and can move back and forth in the central hole of the perforated plate 9 to regularize the movement direction of the buffer block 10 and play a guiding role.

[0027] The perforated plate 9 in this embodiment is located on the upper and lower sides of the box body 5, with a hole in the middle. The round steel bar 8 moves back and forth in the middle hole to limit the movement direction of the round steel bar 8, thereby regularizing the movement trajectory of the buffer block 10.

[0028] The buffer block 10 in this embodiment is located at the front end of the buffer device and is in direct contact with the steel plate, and is used to achieve a transition between the steel plate and the spring 6; the inclined surface above the buffer block 10 plays a guiding role, and can guide the steel plate to the action position of the buffer block 10 to prevent the steel plate from falling above the buffer block 10 and being unable to be placed on the rack normally.

[0029] The lead screw 1 in this embodiment is an M30 lead screw 1, the nut 2 is an M30 nut 2, and the round steel bar 8 is an M10 round steel bar 8.

[0030] Before the buffer block 10 extends out in front of the rack stopper of the medium plate turning machine, when the medium plate turning machine is performing the turning operation, the steel plate sliding on the rack first contacts the buffer block 10. The impact kinetic energy is absorbed through the compression deformation of the spring 6 at the rear side of the buffer block 10, reducing the contact speed between the steel plate and the rack stopper of the medium plate turning machine, thereby achieving the buffering effect. During this buffering process, the sleeve 7 inside the spring 6 restricts the swing of the spring 6, enabling the spring 6 to only move back and forth in a straight line in the direction parallel to the sleeve 7, thereby preventing the movement direction of the buffer block 10 from deviating and making the movement trajectory of the buffer block 10 more stable. The perforated plates 9 welded to the upper and lower sides of the buffer device box body 5, the holes in the middle position thereof cooperate with the M10 round steel 8, jointly restricting the movement of the buffer block 10 in other directions except along the direction parallel to the rack, preventing the buffer block 10 from swinging after being stressed and resulting in an unsatisfactory buffering effect. When the buffer device is working, the compression deformation of the spring 6 causes the elastic force to increase. To prevent the elastic force of the spring 6 from causing deformation and other damages to the buffer device, the steel plate at the rear side of the device box body 5 is thickened, and the elastic force of the spring 6 is borne by the box body reinforcement plate 4 to protect the device. To meet the actual production needs, the M30 lead screw 1 at the rear side of the device can adjust the length of the buffer block 10 extending out of the device according to the actual situation. Through the M30 adjusting nut 2 on the M30 lead screw 1, the horizontal movement of the lead screw 1 inside the device is achieved, thereby adjusting the extending length of the buffer block 10. After the adjustment is completed, the M30 locking nut 2 is used to determine that the extending length of the buffer block 10 no longer changes.

[0031] This embodiment buffers the contact between the medium plate turning machine and the stainless steel plate during the turning of the medium plate in medium plate production, preventing the stainless steel plate from directly colliding with the rack stopper of the medium plate turning machine, thereby avoiding problems such as deformation, scratching, notching, flanging, and burrs on the stainless steel plate.
