Description

Technical Field

[0001] The utility model relates to the technical field of threaded steel production, in particular to an extrusion device for threaded steel production. Background Art

[0002] Rebar is the common name for hot-rolled ribbed steel bars. The grade of ordinary hot-rolled steel bars is composed of HRB and the minimum yield point of the grade. H, R, and B are the first letters of the three words "hot rolled", "ribbed", and "bars" respectively.

[0003] In the related art, a Chinese patent document with application number CN202120818262.4 proposes an extrusion device for threaded steel production. When it is used, the extrusion sleeve is placed on the upper end of the limit base, and one end of the first threaded steel and the second threaded steel are respectively placed inside the extrusion sleeve, and the first threaded steel and the second threaded steel are placed on the upper end of the support base. The hydraulic pump drives the first hydraulic cylinder and the second hydraulic cylinder, and the first hydraulic cylinder and the second hydraulic cylinder work simultaneously. The upper extrusion connecting plate and the lower extrusion connecting plate are close to each other to extrude the extrusion sleeve. During the extrusion process, plastic deformation is generated and the surfaces of the first threaded steel and the second threaded steel are tightly pressed to form a joint, thereby realizing the fixation between the first threaded steel and the second threaded steel. The upper extrusion connecting plate and the lower extrusion connecting plate are both semicircular structures, which can fully extrude the extrusion sleeve. The extrusion sleeve is pressed in all directions to achieve connection, and the connection can be achieved by one extrusion action. The multiple convex strips on the inner side of the upper extrusion connecting plate and the lower extrusion connecting plate increase the extrusion area during extrusion, so that an indentation can be formed at the connection, thereby increasing the bite force at the connection. After the extrusion is completed, the integral threaded steel can be removed.

[0004] With respect to the above-mentioned related technologies, the inventors believe that there are the following defects: the device does not explain how to replace the upper extrusion connecting plate and the lower extrusion connecting plate, and when pressing and connecting threaded steel bars of different thicknesses, it is necessary to replace the upper extrusion connecting plate and the lower extrusion connecting plate so that both the upper extrusion connecting plate and the lower extrusion connecting plate are semicircular structures, which can fully extrude the extrusion sleeve, and the extrusion sleeve is subjected to all-round force pressing to achieve connection. In view of this, an extrusion device for threaded steel production is proposed to solve the above-mentioned problem. Utility Model Content

DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] See also Figure 1 and 3 In this embodiment, an extrusion device for producing threaded steel comprises a frame 1, support bases 2 are arranged on the front and rear sides of the frame 1, two limit bases 3 are arranged on the frame 1, hydraulic cylinders 8 are fixed to the upper and lower walls inside the frame 1, a disassembly mechanism 7 is arranged on the hydraulic cylinder 8, a mounting plate 4 is arranged on the disassembly mechanism 7, an extrusion connecting plate 5 is fixed on the mounting plate 4, and an adjustment mechanism 6 is arranged on the frame 1.

[0022] The disassembly mechanism 7 includes a mounting column 702, an insert rod 703, and a mounting groove 706 of a connecting rod 701. The mounting column 702 is fixed to the output end of the hydraulic cylinder 8. A mounting groove 706 is provided in the mounting column 702. Fixed grooves 708 are provided on both sides of the mounting column 702. First threaded rods 704 are provided on both sides of the mounting column 702. The first threaded rods 704 are located inside the fixed grooves 708 and are slidably connected to the fixed grooves 708. A connecting rod 701 is fixed to one side of the mounting plate 4. Threaded grooves are provided on both sides of the connecting rod 701. The relatively close side of the first threaded rod 704 is located inside the threaded groove and is threadedly connected to the threaded groove.

[0023] The device can disassemble the extruded connecting plate 5 by rotating the first threaded rod 704 to move it to the outside of the threaded groove, and then by moving the connecting rod 701 to the outside of the installation groove 706.

[0024] Among them, springs 707 are fixedly installed on both sides of the mounting column 702, a retaining ring is fixed at one end of the first threaded rod 704, and the other side of the spring 707 is rotatably connected to the retaining ring. Through the setting of the spring 707, the first threaded rod 704 is more tightly abutted against the threaded groove.

[0025] At the same time, the connecting rod 701 is located in the mounting groove 706 , which is convenient for preliminary fixing of the extruded connecting plate 5 .

[0026] In addition, slots 705 are provided on both sides of the bottom of the mounting column 702 , and a plug rod 703 is fixed on the mounting plate 4 , and the plug rod 703 is inserted into the inside of the slot 705 , thereby increasing the stability when the extruded connecting plate 5 is fixed.

[0027] See also Figure 1-2 The adjustment mechanism 6 in this embodiment includes a second threaded rod 601 and a sliding rod 607. Two second threaded rods 601 are vertically arranged in the frame 1. A rotating wheel 604 is fixed on the second threaded rod 601. A belt 603 is transmitted between the two rotating wheels 604. A liftable threaded block 605 is threadedly connected to the second threaded rod 601.

[0028] Two slide bars 607 are vertically arranged in the frame 1, and a moving block 606 is slidably mounted on the slide bars 607. Fixed rods 602 are fixed on opposite sides of the moving block 606 and the threaded block 605 to limit the rotation tendency of the threaded block 605 and make it move horizontally.

[0029] The device starts an external motor, which drives one of the second threaded rods 601 to rotate, and then drives the rotating wheel 604 to rotate through the second threaded rod 601, and then the belt 603 is set to make the two second threaded rods 601 rotate at the same time, and then the second threaded rod 601 drives the threaded block 605 to move up and down, and the fixed rod 602 moves with the movement of the threaded block 605, thereby driving the limit base 3 to move up and down. The extrusion sleeve placed on the limit base 3 can be flush with the support base 2, so that the center lines of the two threaded steel bars are always on the same plane, so the docking accuracy of the two threaded steel bars will not be affected.

[0030] One end of one of the second threaded rods 601 is driven to rotate by an external motor, and the opposite sides of the two fixing rods 602 are fixed to the two sides of the limiting base 3 to facilitate driving the second threaded rod 601 to rotate.

[0031] The working principle of the above embodiment is:

[0032] When the extruded connecting plate 5 needs to be replaced, the extruded connecting plate 5 can be disassembled by rotating the first threaded rod 704 to move it to the outside of the threaded groove, and then moving the connecting rod 701 to the outside of the installation groove 706. Conversely, when the extruded connecting plate 5 needs to be installed, the extruded connecting plate 5 can be fixed by rotating the first threaded rod 704 to move it to the inside of the threaded groove.

[0033] When different sizes of threaded steel bars are squeezed and pressed together, since the sizes of the extrusion sleeves are different, it is necessary to adjust the height of the limiting base 3 to ensure the accuracy of the two threaded steel bars to avoid multiple adjustments and docking.

[0034] The external motor drives one of the second threaded rods 601 to rotate, and then the second threaded rod 601 drives the rotating wheel 604 to rotate, and then the belt 603 is set so that the two second threaded rods 601 can rotate at the same time, and then the second threaded rod 601 drives the threaded block 605 to move up and down, and the fixed rod 602 moves with the movement of the threaded block 605, thereby driving the limit base 3 to move up and down.

[0035] The extrusion sleeve placed on the limiting base 3 can be slightly higher or lower than the supporting base 2, so that the extrusion sleeve placed on the limiting base 3 and the threaded steel on the supporting base 2 that supports the threaded steel can be accurately aligned with the extrusion sleeve and inserted into the interior, thereby extruding and pressing the threaded steel.
