AI Technical Summary

Technical Problem

In the existing technology, the pusher pin is subject to axial and radial forces for a long time, which causes it to wear quickly and move easily, often falling off and affecting production. Directly welding bolts to stop it is not effective.

Method used

A bidirectional anti-slip pusher pin device is designed, which adopts a stepped stop, a clamping plate groove and a positioning screw hole structure. Through the cooperation of the clamping plate and the positioning bolt, the two ends of the positioning pin position the workpiece. The positioning screw hole and the clamping plate groove are at a preset distance in the direction of the central axis of the pin body to increase the positioning stability.

Benefits of technology

It effectively prevents the pins from shifting and falling off, improves the stability and reliability of the pins, reduces equipment failures, and ensures production continuity.

Description

Technical Field

[0001] This utility model relates to the field of pusher pin technology, and in particular to a bidirectional anti-slip pusher pin device. Background Technology

[0002] Currently, due to the continuous clamping and rolling of steel on the roughing mill pusher, the pusher is subjected to enormous forces, resulting in severe equipment vibration. Consequently, the pin connecting the pusher and the push rod wears rapidly and frequently detaches due to long-term axial and radial forces, causing downtime and affecting production output. To address this issue, most methods involve directly welding bolts to both ends of the pin. This method not only increases workload but is also unreliable and ineffective, often resulting in unplanned steel plate production and disrupting normal production rhythm. Therefore, this utility model proposes a bidirectional anti-lateral pusher pin device. Utility Model Content

[0003] To solve the above technical problems, this utility model provides a bidirectional anti-slip pusher pin device, which can position the workpiece at both ends of the pin to prevent the pusher pin from falling off when it moves too far.

[0004] The bidirectional anti-slip pusher pin device in this solution includes a pin body and a clamping plate groove on its side wall. A clamping plate is adapted to be inserted into the clamping plate groove. A stepped stop is provided at the end of the pin body away from the clamping plate groove. A positioning screw hole is also provided on the side wall of the pin body, wherein the positioning screw hole is perpendicular to the central axis of the pin body.

[0005] The further defined technical solution of this utility model is:

[0006] Furthermore, it also includes positioning bolts that are adapted to the positioning screw holes.

[0007] Furthermore, the positioning screw hole and the retaining plate groove are spaced at a predetermined distance along the central axis of the pin body.

[0008] Furthermore, the thickness of the step stop is 20mm.

[0009] Furthermore, the main body of the pin is 475mm long and the end face diameter is 120mm.

[0010] The beneficial effects of this utility model are: This utility model provides a bidirectional anti-slip pusher pin device. Through the cooperation of the stepped stop and the clamping plate, the workpiece can be positioned at both ends of the pin to prevent it from falling off when the pusher pin moves too far. At the same time, the positioning screw hole can be used to install bolts to reposition the workpiece on the pin, thereby improving the stability of the pin. Attached Figure Description

[0015] like Figure 1 As shown, the traditional pin body 3 has a retaining plate groove 5 on the outer side wall, into which a retaining plate 4 can be inserted for positioning at one end. To prevent axial movement, bolts are usually welded directly to both ends of the pin to stop it. Therefore, this has been improved.

[0016] like Figure 2 and Figure 3 As shown, this embodiment provides a bidirectional anti-slip pusher pin device, including a pin body 3 and a retaining plate groove 5 opened on its side wall. A retaining plate 4 is adapted to be inserted into the retaining plate groove 5. A stepped stop 7 is provided at the end of the pin body 3 away from the retaining plate groove 5. A positioning screw hole 6 is also opened on the side wall of the pin body 3. The positioning screw hole 6 is perpendicular to the central axis of the pin body 3. A positioning bolt adapted to the positioning screw hole 6 is threadedly connected to the positioning screw hole 6. There is a preset distance between the positioning screw hole 6 and the retaining plate groove 5 in the direction of the central axis of the pin body 3.

[0017] Specifically, the stepped stop 7 at the end of the pin body 3 can position the left end of the workpiece on the pin. After the clamping plate 4 is inserted into the clamping plate groove 5, the right end of the pin body 3 has a second positioning line 9, which positions the right end of the pin. At the same time, the positioning bolt is threaded into the positioning screw hole 6, so that the pin body 3 also has a first positioning line 8. The clamping plate 4 and the positioning bolt can be used simultaneously to position the workpiece at different positions at the end of the pin body 3 away from the stepped stop 7 (i.e., the right end), resulting in a better fastening effect.

[0018] Specifically, in this embodiment, the step stop 7 is 20mm thick, the main body of the pin 3 is 475mm long, and the end face diameter is 120mm.

[0019] In addition to the above embodiments, this utility model may have other implementation methods; all technical solutions formed by equivalent substitution or equivalent transformation fall within the protection scope claimed by this utility model.
