Description

Technical Field

[0001] The utility model relates to the technical field of steel cage processing equipment, in particular to a positioning and feeding device for a steel cage forming machine. Background Art

[0002] The main function of the steel cage is the same as the stress of the longitudinal steel bars of the column. It mainly plays a tensile role. The compressive strength of concrete is high but the tensile strength is very low. It plays a restraining role on the pile concrete so that it can withstand a certain axial tension.

[0003] At present, in the process of building construction, it is often necessary to tie a steel cage on site. In the prior art, the steel cage is generally composed of four main bars forming a rectangular structure and a number of secondary bars fixed to the outside of the four main bars by tying wires. When the steel cage is tied on site, the main bar frame of the rectangular structure usually needs to bend the ends of the straight steel bars by a bending machine or weld two semi-bent steel bars into a rectangle. In the process of arranging the steel bars, all the transverse bars and longitudinal bars need to be manually lifted and placed on the reinforcement platform. This process is heavy physical repetitive labor, low efficiency, and high labor intensity, which greatly affects the production efficiency of the steel cage and cannot meet the needs of mass production of the steel cage.

[0004] Therefore, developing a new automatic feeding device for steel cages and changing the traditional structural form not only has urgent research value, but also has good economic benefits and industrial application potential. Utility Model Content

[0005] The utility model aims to provide a positioning feeding device for a steel cage forming machine, which adopts automatic feeding to replace manual feeding, reduces the labor intensity of workers and improves the production efficiency of the steel cage.

[0006] The utility model is realized by the following technical solutions:

[0007] A positioning and feeding device for a steel cage forming machine, comprising:

[0008] A longitudinal reinforcement conveying mechanism, the longitudinal reinforcement conveying mechanism comprises an adjusting mechanism and a front longitudinal reinforcement conveying mechanism; the adjusting mechanism is connected to the top of the front longitudinal reinforcement conveying mechanism and drives the front longitudinal reinforcement conveying mechanism to reciprocate in the longitudinal direction;

[0009] A discharge device, which automatically conveys the longitudinal reinforcement to the front longitudinal reinforcement conveying mechanism. When the adjusting mechanism drives the front longitudinal reinforcement conveying mechanism to move forward in the longitudinal direction, the front longitudinal reinforcement conveying mechanism clamps the longitudinal reinforcement and conveys the longitudinal reinforcement to the welding conductive mechanism. When the adjusting mechanism drives the front longitudinal reinforcement conveying mechanism to move backward in the longitudinal direction, the front longitudinal reinforcement conveying mechanism releases the longitudinal reinforcement and resets.

[0010] In this solution, the discharging device is an automatic discharging mechanical arm. The discharging device automatically inserts all the longitudinal reinforcements into the front longitudinal reinforcement conveying mechanism. At this time, the front longitudinal reinforcement conveying mechanism will move toward the welding conductive mechanism according to the set conveying length under the drive of the adjusting mechanism. When the longitudinal reinforcement welding is completed, the adjusting mechanism will continue to drive the front longitudinal reinforcement conveying mechanism to move toward the welding conductive mechanism until the welding of the steel cage is completed. The whole process completely replaces manual feeding, thereby achieving the purpose of reducing the labor intensity of workers and improving the production efficiency of the steel cage.

[0011] As a further technical solution to the positioning and feeding device, the front-section longitudinal rib conveying mechanism includes a first conveying unit for conveying the longitudinal ribs and a first adjustment plate for fixing the first conveying unit, the first adjustment plates are arranged in multiple groups along a transverse array, the first conveying units are arranged in pairs along the longitudinal direction of the first adjustment plates, and a first conveying cavity for clamping the longitudinal ribs is arranged inside the first conveying unit.

[0012] As a further technical solution of the positioning and feeding device, the feed port and the discharge port of the first conveying cavity are respectively provided with a first positioning column and a second positioning column, and the outer ends of the first positioning column and the second positioning column both extend in the direction of the longitudinal ribs.

[0013] As a further technical solution of the positioning and feeding device, the axial cross-section of the inner cavity of the first positioning column and the second positioning column is trumpet-shaped, which prevents the longitudinal reinforcement from being deformed during transportation and not being accurately delivered to the next workstation.

[0014] As a further technical solution of the positioning and feeding device, the longitudinal reinforcement conveying mechanism also includes a rear-stage longitudinal reinforcement conveying mechanism, which is located between the front-stage longitudinal reinforcement conveying mechanism and the welding conductive mechanism. The rear-stage longitudinal reinforcement conveying mechanism includes a second conveying unit for conveying the longitudinal reinforcement and a second adjustment plate for fixing the second conveying unit. The second adjustment plate is arranged in a transverse array and corresponds to the first adjustment plate one by one. The second conveying unit is arranged in pairs along the longitudinal direction of the second adjustment plate. A second conveying cavity for clamping the longitudinal reinforcement is arranged inside the second conveying unit, and the clamping action of the second conveying cavity is opposite to that of the first conveying cavity. When the longitudinal reinforcement is inserted into the front-stage longitudinal reinforcement conveying mechanism, the first conveying cavity is in an open state and the second conveying cavity is in a closed state. At this time, when the end of the inserted longitudinal reinforcement is against the second conveying cavity, the ends of all the longitudinal reinforcements will be aligned. When the ends of all the longitudinal reinforcements are aligned, the first conveying cavity clamps the longitudinal reinforcement and the second conveying cavity is in an open state. In this way, the longitudinal reinforcement can be transported to the upper longitudinal reinforcement welding mechanism for welding in a flush manner, thereby improving the production quality of the steel cage.

[0015] As a further technical solution to the positioning and feeding device, the feed port and the discharge port of the second conveying cavity are respectively provided with a fifth positioning column and a fourth positioning column, and the outer ends of the fifth positioning column and the fourth positioning column both extend in the direction of the longitudinal reinforcement, thereby preventing the longitudinal reinforcement from being accurately conveyed to the next workstation due to deformation during transportation.

[0016] As a further technical solution of the positioning and feeding device, a third positioning column is provided at the discharge end of the second positioning column, a sixth positioning column is provided at the feed end of the fifth positioning column, and the outer diameter of the third positioning column is smaller than the inner cavity diameter of the sixth positioning column.

[0017] As a further technical solution to the positioning and feeding device, the adjustment mechanism includes a third driving device, a support frame and a sliding rail. The upper and lower ends of the support frame are respectively connected to the frame and the sliding rail. The top of the front longitudinal rib conveying mechanism is matched and connected to the T-shaped protrusion of the sliding rail. The output end of the third driving device is connected to the top of the front longitudinal rib conveying mechanism, and drives the front longitudinal rib conveying mechanism to reciprocate along the sliding rail.

[0018] As a further technical solution of the positioning and feeding device, adjustment rails capable of slidingly adjusting the spacing are provided between the first adjustment plate and the second adjustment plate and the frame (13), so that the device can produce steel cages with various specifications.

[0019] As a further technical solution of the positioning and feeding device, the axial cross-section of the inner cavity of the fifth positioning column and the fourth positioning column is trumpet-shaped, which prevents the longitudinal reinforcement from being unable to be accurately delivered to the next workstation due to deformation during transportation.

[0020] It can be seen from the above technical scheme that the present application provides a positioning feeding device for a steel cage forming machine, including a longitudinal reinforcement conveying mechanism and a discharge device. The discharge device automatically conveys the longitudinal reinforcement to the front longitudinal reinforcement conveying mechanism. When the adjustment mechanism drives the front longitudinal reinforcement conveying mechanism to move forward in the longitudinal direction, the front longitudinal reinforcement conveying mechanism clamps the longitudinal reinforcement and conveys the longitudinal reinforcement to the welding conductive mechanism. When the longitudinal reinforcement welding is completed, the adjustment mechanism will continue to drive the front longitudinal reinforcement conveying mechanism to move toward the welding conductive mechanism until the steel cage welding is completed. The entire process completely replaces manual feeding, achieving the purpose of reducing the labor intensity of workers and improving the production efficiency of the steel cage; at the same time, the rear longitudinal reinforcement conveying mechanism located between the front longitudinal reinforcement conveying mechanism and the welding conductive mechanism can align the ends of all the longitudinal reinforcements, so that the longitudinal reinforcements can be conveyed to the upper longitudinal reinforcement welding mechanism for welding in a flush manner, thereby improving the production quality of the steel cage.
