Abstract

The utility model discloses a sizing mechanism in a hydraulic follow-up shearing machine. The mechanism is used for sizing and cutting steel bars, and plays a vital role in the sizing precision and surface cutting quality of steel bars. In order to overcome the inaccurate sizing accuracy, material clamping and large error existing in the existing sizing mechanism, a high-precision sizing mechanism is proposed. The utility model adopts the sizing plate 3 to be connected on the positioning block 6 through the bearing pin 4. The spring 13 connects the scale plate 3 and the slide block 8 through the set screws 9 and 14. The set screw 9 fixes the spring 13 on the slider 8 . The position of the slide block 8 is adjusted by the right adjustment screw 10 and the left adjustment screw 12, so that the return speed of the scale plate 3 can be adjusted. The cut-to-length plate 3 is installed at the bottom of the angle steel 2, which increases the contact area between the steel bar 1 and the cut-to-length plate 3, avoids the blocking phenomenon between the steel bar 1 and the cut-to-length plate 3, improves the surface quality of the steel bar, and increases the cut-to-length accuracy.

Description

Hydraulic Follow-up Shearing Mechanism

technical field

The utility model relates to a high-precision hydraulic follow-up shearing machine sizing mechanism, which can be used for sizing and cutting threaded steel bars, high-strength steel wires and PC steel bars of different diameters and materials. the

Background technique

With the rapid development of the construction and sleeper industry, threaded steel bars have been widely used, but the shearing effect, speed and accuracy of the domestically produced hydraulic follow-up shears for threaded steel bars are not very satisfactory, mainly because the hydraulic follow-up shears The shearing machine's sizing board has low sizing accuracy, insensitive reflection and large errors. If no measures are taken, there will be a large number of elbows, high non-straightness, and even secondary processing of steel bars. the

Contents of the invention

In order to overcome the above-mentioned deficiencies in the existing hydraulic servo shearing machine sizing mechanism, the utility model provides a high-precision sizing mechanism. The utility model realizes the sizing and cutting of the steel bar through the contact between the sizing plate and the steel bar, and the sizing The plate is installed at the bottom of the angle steel, which increases the contact area between the steel bar and the fixed-length plate, avoids the blocking phenomenon between the steel bar and the fixed-length plate, improves the surface quality of the steel bar, and increases the precision of the fixed-length plate. the

The technical solution adopted by the utility model to solve the technical problem is: a high-precision hydraulic follow-up shearing machine sizing mechanism, including angle steel 2, sizing plate 3, positioning block 6, slide block 8, pin shaft 4; The scale plate 3 and the positioning block 6 are fixed on the bottom of the angle steel 2; the scale plate 3 is connected to the positioning block 6 through the pin shaft 4, and the positioning block 6 is fixed on the angle steel 2 through the screw 5; the proximity switch 7 is fixed on the angle steel 2 through the thin nut 11 On the positioning block 6; the spring 13 connects the scale plate 3 and the slider 8 through the set screws 9 and 14; the set screw 9 fixes the spring 13 on the slider 8; adjusts the slide through the right adjustment screw 10 and the left adjustment screw 12 The position of block 8 connects scale plate 3 and slide block 8 through set screw 9,14, can regulate spring 13 tensioning forces. The positioning device structure of this mechanism is made up of slide block 8 and positioning block 6. the

Detailed ways

Fig. 1 is an embodiment (seeing Fig. 1) disclosed by the utility model, and the fixed length plate 3 is connected on the positioning block 6 through pin shaft 4, and the fixed length plate 3 can rotate around it. The proximity switch 7 is fixed on the positioning block 6 through the lock nut 11, and the distance between the proximity switch 7 and the scale plate 3 can be adjusted by the lock nut 11, and the corresponding action time can be adjusted. By adjusting the set screw 1 and the set screw 2, the position of the slider 8 is moved, and the deformation of the spring 13 is changed to adjust the response time of the sizing plate 3 . The spring 13 is respectively fixed on the scale plate 3 and the slide block 8 by the right adjusting screw and the left adjusting screw. the

The sizing mechanism is fixed under the angle steel 2, the steel bar 1 hits the sizing plate 3 under the action of traction, the sizing plate 3 rotates around the pin shaft 4, the spring 13 is stretched, the sizing plate 3 is separated from the proximity switch 7, and the proximity switch 7 Response, send out electrical signal, hydraulic pressure follower shear action, cut steel bar. Because the sizing device is fixed to the lower side of the angle steel 2, the sizing plate 3 has no phenomena such as material clamping to the steel bars, which greatly improves the sizing accuracy of the hydraulic follow-up shearing machine. the
