Description

Technical Field

[0001] The utility model relates to the technical field of steel bar processing, in particular to a clamping and unloading device of a vertical steel bar bending machine. Background Art

[0002] With the rapid development of high-speed railway and expressway construction, due to the complex and diverse geographical environment, many elevated bridges must be erected during road construction. The basic work of elevated bridges is to make corresponding pile foundation cages. Therefore, low-cost, simple and efficient production of road and bridge pile foundation cages is the common goal pursued by the construction party and the supervision party, and beam tie bar forming welding technology is the key link in the production of pile foundation cages. Beam tie bars are one of the commonly used connecting steel bars in engineering. They are used to connect beams and columns, beams and walls and other structures, and play a role in enhancing structural rigidity and stability. In the current beam tie bar production process, the bending process of the hooks at both ends of the beam tie bars is usually carried out by a horizontal steel bar bending machine.

[0003] A Chinese patent with authorization announcement number CN212310688U discloses a steel bar bending machine, which mainly arranges a steel bar side bending device and a steel bar pushing device at both ends of the length direction of the steel bar processing section of the machine base, and is provided with two steel bar bending devices arranged in sequence along the length direction of the steel bar processing section, so that a steel bar bending device is used to first perform a bending process on one end of a steel bar placed in the steel bar processing section of the machine base, and then the steel bar pushing device pushes the first bent end of the steel bar to the steel bar side bending device to perform side bending process to form a laterally deflected hook portion, and then another steel bar bending device performs bending process on the other end of the steel bar, so that the tie steel bar with a laterally deflected hook portion can be manufactured in an automated manner.

[0004] The above-mentioned existing technical solutions have the following defects: when the above-mentioned steel bar bending machine processes beam reinforcement, two steel bar bending devices are used to clamp and synchronously bend the two ends of the steel bar at the same time. Since the clamping method of the steel bar bending machine is relatively simple, it is often difficult to achieve stable clamping of the steel bar. Since the middle part of the steel bar is suspended in the air, it is easy to cause the steel bar to deviate or slide during the bending process, thereby affecting the processing accuracy and efficiency, and needs to be improved. Utility Model Content

[0005] The problem to be solved by the utility model is to provide a clamping and unloading device for a vertical steel bar bending machine in view of the above-mentioned deficiencies existing in the prior art. The device is arranged between two machining centers of the vertical steel bar bending machine to complete the clamping of the middle section of the steel bar and the unloading after the bending is completed, which is beneficial to the machining accuracy and efficiency while avoiding the deviation or sliding phenomenon in the steel bar bending process.

[0006] The above utility model object of the utility model is achieved through the following technical solutions:

[0007] A clamping and unloading device for a vertical steel bar bending machine includes a Z-axis linear module, a Y-axis linear module and a lower mounting seat arranged at the movable end of the Z-axis linear module, a lower clamping plate arranged at the movable end of the Y-axis linear module, an upper mounting seat slidably engaged and locked on the lower mounting seat through an intermediate connecting piece, and an upper clamping plate arranged above the lower clamping plate and arranged on the upper mounting seat, wherein a clamping gap is formed between the lower clamping plate and the upper clamping plate for the steel bars to pass through.

During processing, the two ends of the steel bar will be pre-lapped on the workbenches of the two processing centers, and the clamping and unloading device first adjusts the position of the upper mounting seat through the intermediate connecting piece according to the diameter of the steel bar, so that the plate surface of the lower clamping plate and the upper side surface of the steel bar are approximately at the same height; then the Z-axis linear module is used to drive the lower clamping plate and the upper clamping plate to move close to the upper and lower sides of the steel bar, and the Y-axis linear module is used to drive the lower clamping plate to move close to the upper clamping plate, so as to complete the clamping and limiting of the steel bar by the lower clamping plate and the upper clamping plate; when the bending of the steel bar is completed, the Z-axis linear module and the Y-axis linear module are activated again, first driving the steel bar away The vertical rebar bending machine is separated from the vertical rebar bending machine to facilitate the subsequent loading of rebars, and then the lower clamping plate is moved away from the upper clamping plate to release the clamping limit of the rebar, so that the rebar can be smoothly disengaged from the clamping gap, and rapid unloading is achieved, further improving the processing efficiency; in this process, the clamping gap formed between the lower clamping plate and the upper clamping plate provides a stable clamping environment for the rebar, and the combination of the Z-axis linear module and the Y-axis linear module, as well as the sliding engagement design between the lower mounting seat and the upper mounting seat, achieves precise clamping of the rebar in three-dimensional space, and also makes it possible to easily unlock and quickly adjust when the clamping gap needs to be adjusted or other operations need to be performed, which also provides convenience for the clamping and unloading of the rebar, while avoiding offset or sliding during the rebar bending process, which is beneficial to processing accuracy and efficiency.

One end of the fastening bolt is threadedly connected to the lower mounting seat, and the other end tightly abuts against the outer surface of the upper mounting seat.

[0014] By adopting the above technical solution, after the upper mounting seat and the lower mounting seat are buckled, they are approximately in a U shape. After tightening the fastening bolts, the rack and the tooth groove are tightly meshed, thereby completing the fixed installation between the upper mounting seat and the lower mounting seat; when the diameter of the steel bar changes, the fastening bolts can be loosened, and the upper mounting seat can be moved to a predetermined height.

[0030] During the bending process of the beam reinforcement, the control of its clamping stability and precision is the key to ensuring the processing quality; the clamping and unloading device of the utility model is used to be installed between the two processing centers of the vertical steel bar bending machine. During processing, the two ends of the steel bar will be pre-lapped on the workbench of the two processing centers. The clamping and unloading device first adjusts the position of the upper mounting seat 6 through the intermediate connecting piece 5 according to the diameter of the steel bar, so that the plate surface of the lower clamping plate 4 and the upper side surface of the steel bar are approximately at the same height; then the Z-axis linear module 1 drives the lower clamping plate 4 and the upper clamping plate 7 moves close to the upper and lower sides of the steel bar, and drives the lower clamping plate 4 to move close to the upper clamping plate 7 through the Y-axis linear module 2 to complete the clamping and limiting of the steel bar by the lower clamping plate 4 and the upper clamping plate 7; when the steel bar is bent, the Z-axis linear module 1 and the Y-axis linear module 2 act again, first driving the steel bar away from the vertical steel bar bending machine to facilitate the subsequent loading of the steel bar, and then moving the lower clamping plate 4 away from the upper clamping plate 7 to release the clamping and limiting of the steel bar, so that the steel bar can be smoothly separated from the clamping gap, realizing rapid unloading, and further improving the processing efficiency. During this process, a stable clamping environment is provided for the steel bars through the clamping gap formed between the lower clamping plate 4 and the upper clamping plate 7, and the combination of the Z-axis linear module 1 and the Y-axis linear module 2, and the sliding engagement design between the lower mounting seat 3 and the upper mounting seat 6, to achieve precise clamping of the steel bars in three-dimensional space.

The Y-axis cylinder 21 drives the lower clamping plate 4 to move closer to or away from the upper clamping plate 7 by extending and retracting the piston rod, and the cylinder driving method can enable the lower clamping plate 4 and the upper clamping plate 7 to maintain an appropriate pre-pressure on the steel bar, so as to complete the clamping and limiting of the steel bar.

At the same time, the first guiding surface 511 can also prevent the tooth part from being damaged due to improper operation to a certain extent during the adjustment process, enhancing the service life and stability of the device. After tightening the fastening bolt 54, the rack 51 and the tooth groove 52 are tightly meshed, thus completing the fixed installation between the upper mounting seat 6 and the lower mounting seat 3; when the diameter of the steel bar changes, the fastening bolt 54 can be loosened, and the upper mounting seat 6 can be moved to a predetermined height.
