Description

Technical Field

[0001] The utility model belongs to the technical field of steel wire straightening, and more specifically, particularly relates to a pneumatic steel wire straightening device. Background Technique

[0002] During the processes of rolling, drawing and other processing and transportation of steel wires, due to external forces or uneven cooling, bending and distortion phenomena with different curvatures may occur. These bends and distortions will affect the use of the steel wires, and operators often hold a hammer in one hand to strike and straighten the bent steel wires.

[0003] Based on the above, when performing the steel wire straightening operation, the operator needs to firmly hold the handle of the hammer with one hand, while the other hand needs to hold one end of the steel wire, not only to control its stability, but also to adjust the angle in a timely manner to meet the requirements of straightening. This process has high requirements for the precise control of the force and the smooth coordination of the actions. A slight mistake will cause risks and requires high physical strength from the operator. Content of the Utility Model

[0058] The operator stands in front of the operating table 1, holds the front end of the wire to be hammered straight, places the remaining part on the operating table 1, starts the driving cylinder 6, and the driving cylinder 6 drives the hammer 8 to move up and down through the up and down movement of the piston rod and the connection of the connecting member 7, so as to perform the hammering straightening operation on the wire to be hammered straight. During the upward movement of the hammer 8, the operator can continuously flip and adjust the angle of the wire until the wire is hammered straight. Example 2:

[0059] On the basis of Example 1, as shown in the attached Figure 1 to the attached Figure 5As shown in the figure, it further includes a reciprocating movement component, which is arranged behind the support frame 2 and inside the transmission box 3.

[0060] Among them, the reciprocating movement component includes:

[0061] A transmission lead screw 10, which is rotatably connected inside the fixed block 9;

[0062] An operation knob 1001, which is coaxially and fixedly connected to the front end of the transmission lead screw 10;

[0063] A limit slider 11, which is slidably connected inside the fixed block 9. The limit slider 11 is threadedly connected to the transmission lead screw 10. The function is that by rotating the operation knob 1001, the limit slider 11 can be driven to slide back and forth through the threaded transmission mechanism jointly constituted by the limit slider 11 and the transmission lead screw 10.

[0064] Among them, the reciprocating movement component further includes:

[0065] Two connecting springs 12, and the upper ends of the two connecting springs 12 are dispersedly and fixedly connected to the rear of the support frame 2;

[0066] A connecting plate 13, which is fixedly connected to the lower ends of the two connecting springs 12. The function is that after the limit slider 11 slides forward until it no longer contacts the connecting plate 13, under the action of the connecting spring 12, the connecting plate 13 moves downward to fit with the upper surface of the hammer 8, so that when the hammer 8 moves up and down, it will drive the connecting plate 13 to move synchronously.

[0067] Among them, the reciprocating movement component further includes:

[0068] Two connecting rods 14, and the two connecting rods 14 are dispersedly and fixedly connected to the upper surface of the connecting plate 13. The left connecting rod 14 is slidably connected to the fixed box 4;

[0069] A transmission rack 15, which is fixedly connected to the upper surface of the right connecting rod 14;

[0070] A transmission gear 16, which is rotatably connected inside the fixed box 4. The transmission gear 16 meshes with the transmission rack 15. The function is that under the guidance of the left connecting rod 14 and the fixed box 4, the up and down movement of the connecting plate 13 will drive the transmission gear 16 to rotate through the gear-rack transmission mechanism jointly constituted by the meshing of the transmission gear 16 and the transmission rack 15.

[0074] The driving pawl 1701 is coaxially and fixedly connected to the right end of the reciprocating lead screw 17. The driving pawl 1701 meshes with the driving ratchet wheel 1601. The function is that under the action of the ratchet and pawl transmission mechanism formed by the meshing of the driving pawl 1701 and the driving ratchet wheel 1601, only when the connecting plate 13 moves upward will the reciprocating lead screw 17 rotate. The rotation of the reciprocating lead screw 17 will drive the driving cylinder 6 and the hammer 8 to move left and right through the thread transmission mechanism formed with the connecting slider 5.

[0075] The specific usage method and function of this embodiment:

[0076] When some steel wires with longer lengths and more bending points need to be straightened, the operator first rotates the operation knob 1001, which can drive the limiting slider 11 to slide back and forth through the thread transmission mechanism formed by the limiting slider 11 and the transmission lead screw 10. After the limiting slider 11 slides forward until it no longer contacts the connecting plate 13, under the action of the connecting spring 12, the connecting plate 13 moves downward to fit the upper surface of the hammer 8, so that when the hammer 8 moves up and down later, it will drive the connecting plate 13 to move synchronously; then the operator stands on the left or right side of the operation table 1, holds the front end of the steel wire to be straightened, places the steel wire horizontally on the operation table 1, and then starts the driving cylinder 6. When the driving cylinder 6 drives the connecting plate 13 to move upward, under the guidance of the left connecting rod 14 and the fixed box 4, it will drive the transmission gear 16 to rotate through the gear-rack transmission mechanism formed by the meshing of the transmission gear 16 and the transmission rack 15. The transmission gear 16 drives the reciprocating lead screw 17 to rotate through the ratchet and pawl transmission mechanism formed by the meshing of the driving pawl 1701 and the driving ratchet wheel 1601. The rotation of the reciprocating lead screw 17 will drive the driving cylinder 6 and the hammer 8 to move left and right through the thread transmission mechanism formed with the connecting slider 5, so as to automatically adjust the left and right positions of the hammer 8. When the driving cylinder 6 drives the hammer 8 to fall, under the action of the ratchet and pawl transmission mechanism formed by the meshing of the driving pawl 1701 and the driving ratchet wheel 1601, the reciprocating lead screw 17 will not rotate, so that the hammer 8 can straighten the steel wire at the current position, thus completing a reciprocating movement of the hammer 8. As the hammer 8 moves left and right, the longer steel wire is straightened.
