Description

Technical Field

[0001] The invention relates to the technical field of rack processing equipment, in particular to a rack metal pipe bending equipment. Background Art

[0002] The metal pipes of the racks are the main supporting structure of the racks. With the multifunctionalization of the racks, the steel pipes required for the production of the racks are also diverse. Therefore, in the production process of the racks, it is necessary to use a bending machine to bend the steel pipes. However, the existing bending machines have fewer restrictions on metal pipes during operation, which causes the metal pipes to fall off during the bending process and easily injure the staff, thus affecting the safety of the steel pipe bending. Unbent metal pipes are usually set up in large quantities. Affected by the storage environment, metal pipes with lubricating oil on the surface are more likely to be stained with stones and dust. If the metal pipes with stones and dust pass through the clamping wheel, after the bending process, the metal pipes are prone to local dents, or the clamping effect of the clamping wheel is reduced. If they are not cleaned in time, the bending effect or the metal pipe will be affected. Traditional bending equipment is either complex in structure or single in function, and only realizes the bending function. In order to improve the use effect of the bending equipment, the inventor studied and proposed this case. Summary of the invention

[0003] The invention provides a metal pipe bending device for a storage rack, which overcomes the shortcomings described in the background technology.

[0004] The technical solution adopted by the present invention to solve its technical problem is:

[0005] A metal pipe bending device for a storage rack includes a machine platform, a holding frame, a functional component, a bending assembly, a clamping assembly, and a mounting frame. The machine platform is equipped with a plurality of holding frames for mounting metal pipes. The clamping assembly includes a first clamping wheel, a second clamping wheel, a cylinder, and a toothed plate. The first clamping wheel and the second clamping wheel are rotatably mounted on the wheel frame, and the wheel frame is mounted on the mounting frame. A gear is coaxially mounted below the first clamping wheel, and the first clamping wheel rotates synchronously with the gear. The movable end of the cylinder is connected to the toothed plate, and the toothed plate is meshed with the gear. The bending assembly includes a plurality of clamping wheels, a plurality of clamping wheels, and a plurality of clamping wheels. It includes a servo motor, a bending part, and a limiter. The output end of the servo motor controls the rotation of the bending part. The top of the bending part is threadedly connected to the limiter. The functional component and the holding frame are located in the forward direction when the metal pipe is placed in the clamping assembly. The functional component includes an outer frame, a clamping wheel, a nozzle, a bottom hydraulic part, a rack rod, and a storage bin. A channel is set in the outer frame. Elastic rings are set at both ends of the channel. A number of clamping wheels are installed above the channel. A nozzle is set between adjacent clamping wheels. A bottom hydraulic part is slidably installed in the rack rod, and a storage bin is installed at the side end of the rack rod. The limiter is specifically threadedly connected to the bending part through a threaded rod at the bottom end of the limiter. Based on this structure, the relative height and direction of the limiter can be adjusted. The structural opening on the holding frame for fixing the metal pipe can be oriented to limit the metal pipe laterally. Some holding frames can be lateral opening structures.

[0006] The storage rack metal pipe bending equipment in the present invention controls the rotation of the bending part through a servo motor, and the main part of the metal pipe is restricted by the handle, the outer frame, the first clamping wheel, and the second clamping wheel, thereby realizing the bending action; a toothed plate frame can be provided to ensure the stability of the toothed plate when it is controlled by the cylinder to move telescopically, and then the toothed plate precisely engages with the gear under the first clamping wheel to rotate; the first clamping wheel and the second clamping wheel hold the metal pipe, and when the first clamping wheel rotates, it realizes the action of passing the metal pipe forward. The outer frame part cooperates with the displacement bottom hydraulic part and the clamping wheel to efficiently clamp the metal pipe, which can cooperate with the clamping assembly to efficiently clamp the metal pipe at the front and rear ends when bending, effectively avoiding the problem of inaccurate bending position caused by displacement of the bending part when the metal pipe is too long. The functional component can not only clamp the metal pipe, but also cooperate to clean impurities on the surface of the metal pipe.

[0007] A better technical solution: the elastic ring is symmetrically provided with a pointed structure, the metal pipe is a cylinder, and the hole on the elastic ring is circular, and the elastic ring is nested and fixed on the outer frame; the circular hole on the elastic ring is slightly smaller than the metal pipe, and when the metal pipe extends through the elastic ring, the elastic ring structure will perform a scraping action on the metal pipe, thereby removing large-volume debris, such as stones, from the metal pipe to a certain extent.

[0008] A better technical solution: The clamping wheel is installed on the auxiliary frame through the rotation of the shaft, and the auxiliary frame is locked and installed on the outer frame. The top of the shaft is fitted with an arc seat, and the auxiliary frame is prefabricated with a notch for the arc seat to move. The top of the arc seat and the inner top surface of the outer frame are provided with a clamping spring. The clamping wheel is made of rubber and has a certain elasticity, which is convenient for holding the metal pipe; multiple clamping wheels cooperate with the nozzle to effectively ensure that the cleaning liquid is coated on the surface of the metal pipe, and the cleaning liquid removes the oil on the surface of the metal pipe; cooperate with the elastic ring to improve the effect of removing the oil on the surface of the metal pipe.

[0009] A preferred technical solution: the nozzles are double-headed and face the lower left and lower right directions respectively; a hollow cavity is prefabricated in the outer frame, and the hollow cavity is connected to the nozzles.

[0010] A better technical solution: an oil path cavity is set in the frame rod, the bottom hydraulic part is I-shaped, and the bottom hydraulic part includes an upper sealing plate and a lower sealing plate. A rectangular block is set in the frame rod, the rectangular block is located above the lower sealing plate, and a reset spring is set between the rectangular block and the lower sealing plate. The reset spring effectively improves the reset effect of the bottom hydraulic part after displacement, and can cooperate with the input and output of the oil of the lower sealing plate to efficiently restore the bottom hydraulic part to the initial position. The displacement of the bottom hydraulic part is controlled by the oil pump to control the input or output of the oil under the lower sealing plate; in specific applications, the input of the oil is through the input pipe, and the output is through the output pipe, and the input pipe and the output pipe are provided with a one-way valve of the corresponding conveying direction.

[0011] A better technical solution: a rubber plate is attached to the top of the upper sealing plate and is set in a corresponding shape. The elasticity of the rubber plate cooperates with the clamping wheel to achieve efficient clamping of the metal pipe.

[0012] A better technical solution: The inner bottom surface of the outer frame is provided with a retaining plate and an inclined plate, a flow port is provided between the retaining plate and the inclined plate, a filter plate is provided at the flow port, and the flow port is connected with the space above the lower sealing plate. The retaining plate is used to assist the upper sealing plate in precise displacement, and the inclined plate is used to improve the flow efficiency of the cleaning liquid; when the bottom hydraulic part is in the initial position, the bottom end of the upper sealing plate will not block the flow port, so that a temporary storage space is formed between the upper sealing plate and the lower sealing plate for temporary storage of the cleaning liquid.

[0013] A better technical solution: storage bins are provided on both sides of the rack.

[0014] A better technical solution: a transparent window is nested on the outer surface of the storage bin, and a transmission pipe is connected to the top of the storage bin, which can cooperate with the pump body to transfer the cleaning liquid in the storage bin. One end of the transmission pipe can be connected to the hollow cavity at the nozzle to realize the recycling of the cleaning liquid.

[0015] A better technical solution: the top of the storage bin is nested and installed in the upper outer frame, and a magnetic block is set at the bottom of the storage bin. The magnetic block at the bottom can absorb the magnetic impurities of the precipitated cleaning liquid, and the transmission pipe is set at the storage bin near the top outlet, so that the foam floating on the top of the storage bin can be transferred along with the cleaning liquid.

[0016] By adopting the above technical solution, the beneficial effects of the present invention are:

[0017] The rack metal pipe bending device of the present invention improves the fixation of the metal pipe by using multiple holding frames and clamping components, and efficiently cooperates with the bending components for bending. The overall structure is simple and the use effect is good. The present invention realizes multi-purpose use of one machine by setting functional components, and can be used to clean impurities sticking to the surface of the metal pipe and improve the bending effect of the metal pipe.
