Description

Technical Field

[0001] The utility model relates to the technical field of bolt processing, in particular to round steel shearing equipment used for producing bolts. Background Art

[0002] A bolt is a mechanical part that is usually used with a nut to connect two or more objects. It usually has a long cylindrical body with an external thread that can match the thread of the matching nut. When the bolt and nut are tightened, they can tightly connect two objects together. When processing bolts, a whole round steel needs to be cut into corresponding lengths before processing.

[0003] A Chinese patent with publication number CN219541834U discloses an automatic cutting device for bolt processing, which cuts round steel by driving a cutting device with a motor, and adjusts the length of the steel by a limit device, thereby realizing cutting of the steel. The front side of the base is shorter than the rear side, so that the steel can roll down after cutting for easy discharge.

[0004] However, the above patent lacks the fixation of the round steel when cutting, which may cause the round steel to shift unstably during the cutting process, thereby causing the cutting position to deviate from the expected one, affecting the cutting quality and accuracy. In addition, the above patent requires workers to manually load the material before each cutting, which not only increases the time and cost of manual operation, but also reduces the processing continuity, resulting in low processing efficiency. Utility Model Content

[0005] The utility model aims to provide a round steel shearing device for producing bolts, which can fix round steel, improve shearing quality and precision, reduce manual feeding, and improve processing continuity and efficiency.

[0006] To achieve the above-mentioned purpose, the technical solution of the utility model is as follows.

[0007] A round steel shearing device for producing bolts comprises an inclined plate, a plurality of sleeves are evenly installed on the upper surface of the inclined plate, two side plates are installed at the end located on the lower side thereof, a baffle is arranged between the two side plates, a U-shaped plate is installed on the upper surface of the inclined plate, a hydraulic cylinder is installed on the upper surface of the U-shaped plate, a lifting plate is installed at the end of the telescopic end of the hydraulic cylinder, and a cutting knife is installed on the lower surface of the lifting plate. Support legs are installed at the bottom of the inclined plate, and a plurality of fixing mechanisms are arranged on both sides of the lower surface of the lifting plate in the width direction of the cutting knife.

[0008] It can be seen that the round steel is placed in the casing, and its end is abutted against the baffle. Through the setting of the fixing mechanism, when the hydraulic cylinder drives the cutting knife to descend to shear the round steel, both sides of the shearing position of the round steel can be fixed, thereby ensuring that the round steel will not be unstably shifted during the shearing process, thereby improving the shearing quality and accuracy, and the sheared steel falls from between the two side plates, while the remaining round steel slides down due to gravity and re-abuts against the baffle, thereby reducing manual loading, reducing the time and cost of manual operation, and improving processing continuity and efficiency.

[0009] Furthermore, the fixing mechanism includes a telescopic rod installed at the bottom of the lifting plate, a clamping block is installed at the end of the telescopic rod, a spring is sleeved on the outer surface of the telescopic rod, and both ends of the spring are respectively in contact with the lifting plate and the clamping block.

[0010] When the hydraulic cylinder drives the cutting knife down to shear the round steel, the two clamping blocks on both sides are first in contact with the round steel, and as the cutting knife continues to descend, the spring is compressed. The compressed spring generates elastic force and drives the clamping blocks to press on the round steel, thereby fixing it. When the hydraulic cylinder drives the cutting knife up, the clamping blocks fall off from the round steel, and the fixation is immediately cancelled. The cut steel falls from between the two side plates, and the remaining round steel slides down due to gravity and re-connects with the baffle.

[0011] Furthermore, a sliding sleeve is provided on the outer surface of the side plate, and the sliding sleeve is connected to the baffle, a plurality of adjustment holes are evenly opened on the side surface of the side plate, and fixing bolts matching the adjustment holes are installed on the outer surface of the sliding sleeve.

[0012] The position of the baffle can be adjusted by setting the sliding sleeve and the adjusting hole, so that the round steel can be cut into steels of different lengths for bolt processing, and the application range is wide.

[0013] Furthermore, a clearance groove is provided on the surface of the inclined plate, and the clearance groove corresponds to the cutting knife.

[0014] The setting of the clearance groove can provide clearance space for the cutting knife, thereby preventing the cutting knife from contacting with the inclined plate and causing collision damage.

[0015] Furthermore, both sides of the upper surface of the lifting plate are connected to limit rods, and the upper ends of the limit rods penetrate to the outer side of the U-shaped plate.

[0016] By setting the limiting rods, both sides of the lifting plate can be limited to improve the stability of the lifting plate when it is lifted or lowered.

[0017] Furthermore, a rubber pad is provided on the inner wall of the clamping block, and an anti-slip pattern is provided on the outer surface of the rubber pad.

[0018] By providing the rubber pad and the anti-skid pattern, the friction force when the clamping block contacts the round steel can be increased, thereby further improving the fixing effect on the round steel. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0024] The utility model is described in detail below with reference to the accompanying drawings.

[0025] like Figure 1-4 As shown, a round steel shearing device for producing bolts includes an inclined plate 100, a plurality of sleeves 108 are evenly installed on the upper surface of the inclined plate 100, two side plates 102 are installed at the end located on the lower side thereof, a baffle 103 is arranged between the two side plates 102, a U-shaped plate 104 is installed on the upper surface of the inclined plate 100, a hydraulic cylinder 105 is installed on the upper surface of the U-shaped plate 104, a lifting plate 106 is installed at the end of the telescopic end of the hydraulic cylinder 105, and a cutting knife 107 is installed on the lower surface of the lifting plate 106. A supporting leg 101 is installed at the bottom of the inclined plate 100, and a plurality of fixing mechanisms 200 are arranged on both sides of the lower surface of the lifting plate 106 in the width direction of the cutting knife 107.

[0026] When in use, workers first put multiple round steels into multiple sleeves 108 respectively. Under the action of gravity, the round steels slide downward and their ends abut against the baffle 103. Then the hydraulic cylinder 105 is started to drive the lifting plate 106 to descend. The lifting plate 106 drives the cutting knife 107 to descend to shear the round steels. Through the setting of the fixing mechanism 200, both sides of the shearing point of the round steel can be fixed before shearing, so as to ensure that the round steel will not be unstable during the shearing process, thereby improving the shearing quality and accuracy, and the sheared steel falls from between the two side plates 102, and the remaining round steel in the sleeve 108 slides down due to gravity and abuts against the baffle 103 again, thereby reducing manual loading, reducing the time and cost of manual operation, and improving processing continuity and efficiency. Workers only need to add round steel to the sleeve 108 at regular intervals.

[0027] Specifically, the fixing mechanism 200 includes a telescopic rod 201 installed at the bottom of the lifting plate 106, and a clamping block 202 is installed at the end of the telescopic rod 201. The outer surface of the telescopic rod 201 is sleeved with a spring 203, and the two ends of the spring 203 are respectively in contact with the lifting plate 106 and the clamping block 202. When the hydraulic cylinder 105 drives the cutting knife 107 to descend to shear the round steel, the two clamping blocks 202 located on both sides are first in contact with the round steel, and as the cutting knife 107 continues to descend, the spring 203 is compressed. The compressed spring 203 generates elastic force and then drives the clamping block 202 to press on the round steel to achieve the purpose of fixing it. When the hydraulic cylinder 105 drives the cutting knife 107 to rise, the clamping block 202 falls off from the round steel, and the fixation is immediately cancelled. The cut steel falls from between the two side plates 102, and the remaining round steel slides down under the action of gravity and re-contacts the baffle 103.

[0028] Specifically, the outer surface of the side plate 102 is sleeved with a sliding sleeve 300, and the sliding sleeve 300 is connected to the baffle 103. A plurality of adjustment holes 301 are evenly opened on the side surface of the side plate 102. The outer surface of the sliding sleeve 300 is installed with fixing bolts 302 adapted to the adjustment holes 301. Through the setting of the sliding sleeve 300 and the adjustment holes 301, the position of the baffle 103 can be adjusted, so that the round steel can be cut into steels of different lengths for bolt processing, and the application range is wide.

[0029] Specifically, a clearance groove 400 is provided on the surface of the inclined plate 100, and the clearance groove 400 corresponds to the cutting knife 107. The setting of the clearance groove 400 can provide clearance space for the cutting knife 107 to avoid collision damage caused by contact between the cutting knife 107 and the inclined plate 100.
