Description

Technical Field

[0001] The present invention relates to the technical field of pipe or bar sawing, and in particular to a pipe or bar transferring device. Background Art

[0002] Currently, long steel pipes and bars need to be cut to the required length using a saw. The sawing process for these types of steel pipes is similar. For example, the process begins by unloading bundles of steel pipes from a truck using a crane. These bundles are then stacked in the workshop's raw material storage area, where support frames are typically installed. However, some operations do not utilize support frames and instead stack the pipes in a cross-shaped pattern. When sawing is required, the crane is used to suspend the top bundle of steel pipes onto the loading rack of the steel pipe sawing machine. After loosening the bundled steel pipes, the steel pipe loading rack is used to load the materials to complete the sawing. The specific structure of the loading rack is the patent number CN201820680372.7, and the patent name is a structure recorded as a loading rack for round tubes or round bars. The sawing host is located at the downstream end of the loading rack and is used to receive the steel pipes or steel bars fed in. The sawing host mainly uses a motor to drive the saw blade to rotate to saw the steel pipes or steel bars. There are relatively mature equipment available on the market for sawing hosts.

[0003] However, the current steel pipe sawing process has the following shortcomings: the current steel pipes are all hoisted in bundles onto the loading rack recorded in CN201820680372.7, and then the steel pipes are loaded one by one through the loading rack. However, this loading method is more complicated when changing the specifications of steel pipes or bars. All scattered pipes on the loading rack need to be sawed before the material change operation can be carried out, which takes a long time to wait. Of course, the stock steel pipes on the loading rack can be removed in the middle, and then steel pipes of other specifications can be replenished. This further increases the labor intensity of the workers and requires a long standby waiting time. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide a pipe or bar transfer device, which can conveniently and quickly transfer the pipes or bars in the material frame to the supporting conveying roller group of the loading station, and the operation is fast and reliable.

[0005] In order to solve the above technical problems, the technical solution of the present invention is: a pipe or rod transfer device, which is installed on a loading rack, and the transfer device includes a transfer rack, and a plurality of transfer slides are slidably installed on the transfer rack, and each transfer slide is installed with a connecting rod lifting mechanism, and the connecting rod lifting mechanism is driven to lift by a transfer lifting power device, and a magnetic block or a transfer clamp is installed at the bottom of the connecting rod lifting mechanism. The loading rack is provided with a loading station and a loading buffer station, and the loading station is provided with a supporting conveying roller group, and the loading rack is provided with a support platform for conveniently supporting the material frame at the loading buffer station, and each transfer slide is synchronously driven by a horizontal transfer power device to slide back and forth synchronously between the loading station and the loading temporary storage position.

[0006] As a preferred solution, the connecting rod lifting mechanism includes a first upper connecting rod and a second upper connecting rod, a first intermediate connecting rod and a second intermediate connecting rod, and a first lower connecting rod and a second lower connecting rod. The middle parts of the first intermediate connecting rod and the second intermediate connecting rod are hinged by an intermediate hinge shaft, and the upper ends of the first intermediate connecting rod and the second intermediate connecting rod are hinged to the lower ends of the first upper connecting rod and the second upper connecting rod respectively through the first upper hinge shaft and the second upper hinge shaft; the upper ends of the first upper connecting rod and the second upper connecting rod are hinged to each other on the transfer slide, and the lower ends of the first intermediate connecting rod and the second intermediate connecting rod are hinged to the upper ends of the first lower connecting rod and the second lower connecting rod respectively through the first lower hinge shaft and the second lower hinge shaft; the lower ends of the first lower connecting rod and the second lower connecting rod are hinged to each other and connected to the magnetic suction block or the transfer fixture, and the transfer lifting power device is a linear power device, which is installed between the first upper hinge shaft and the second upper hinge shaft.

[0007] As a preferred solution, the linear power device is a cylinder, which is fixed on a cylinder seat, and the cylinder seat is rotatably mounted on the first upper articulated shaft or the second upper articulated shaft, and the corresponding piston rod end of the cylinder is mounted on the second upper articulated shaft or the first upper articulated shaft through a connecting sleeve.

[0008] As a preferred solution, the horizontal transfer power device includes a transfer motor and a chain transmission mechanism, the chain transmission mechanism includes two mounting rods rotatably mounted on the transfer frame and extending longitudinally, multiple sets of sprocket groups are fixed on the two mounting rods, and a circulating chain is installed between each set of sprocket groups. One of the mounting rods is connected to the output shaft of the transfer motor, and each circulating chain is fixed to the corresponding transfer slide, and the transfer slide is driven to slide in both directions through the forward and reverse operation of the circulating chain.

[0009] As a preferred solution, the transfer frame includes several vertical poles and several horizontal beams, each vertical pole is fixed on one side of the loading rack and arranged in a row, each horizontal beam is arranged above the vertical pole and spans the loading station and the loading buffer station, each horizontal beam is provided with a horizontal guide rail, the transfer slide is slidably installed on the horizontal guide rail, and a diagonal support rod is provided between the horizontal beam and the vertical pole.

[0010] As a preferred solution, the loading rack is a frame structure, and the supporting platform is provided with a supporting roller group for facilitating the longitudinal movement of the material frame.

[0011] After adopting the above technical scheme, the effect of the present invention is as follows: due to a pipe or rod transfer device, the transfer device includes a transfer frame, a plurality of transfer slides are slidably installed on the transfer frame, each transfer slide is installed with a connecting rod lifting mechanism, the connecting rod lifting mechanism is driven to lift by a transfer lifting power device, a magnetic block or a transfer clamp is installed at the bottom of the connecting rod lifting mechanism, a loading station and a loading buffer station are provided on the loading station, a supporting conveying roller group is provided, and a support for conveniently supporting the material frame is provided on the loading buffer station of the loading rack.

Therefore, the pipe or bar transfer device uses multiple transfer slides to move synchronously to switch the horizontal station, and uses a connecting rod lifting mechanism to effectively drive the magnetic block or transfer fixture to rise and fall, and the connecting rod lifting mechanism occupies less height, so that it can meet the transfer needs in some narrow spaces. In addition, the transfer device can transfer the pipes or bars in the material frame to the supporting conveyor roller group, and the material frame is placed on the supporting platform, and the material frame can be replaced as a whole, which is convenient for switching specifications.

[0012] The cam is connected to the first and second links of the chain, and the cam is connected to the first and second links of the chain. It is installed between the first upper hinge shaft and the second upper hinge shaft. Therefore, after the above-mentioned connecting rod lifting mechanism is adopted, the lifting and lowering of the magnetic block or transfer fixture are driven by the first upper connecting rod and the second upper connecting rod, the first intermediate connecting rod and the second intermediate connecting rod, the first lower connecting rod and the second lower connecting rod. When the linear power device drives the first upper hinge shaft and the second upper hinge shaft to move closer to each other, the magnetic block or transfer fixture descends. When the linear power device drives the first upper hinge shaft and the second upper hinge shaft to separate from each other, the magnetic block or transfer fixture rises. The rising or falling of the magnetic block or transfer fixture does not occupy the space above. Therefore, the height of the loading station and the loading temporary storage position can be lower, which can be suitable for the transfer of materials in some low spaces and meet the transfer of some storage equipment such as vertical warehouses. The transfer device can be placed under the vertical warehouse and occupy a smaller height. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0019] The present invention is further described in detail below through specific examples.

[0020] like Figures 1 to 4 As shown, a pipe or rod transfer device 6 is installed on a loading rack 1, and the loading rack 1 is used to place pipes or rods and supply them to machining equipment. The transfer device 6 includes a transfer frame 61, and a plurality of transfer slides 62 are slidably installed on the transfer frame 61. Each transfer slide 62 is installed with a connecting rod lifting mechanism 64, and the connecting rod lifting mechanism 64 is driven to lift by a transfer lifting power device 647. A magnetic block 65 or a transfer clamp is installed at the bottom of the connecting rod lifting mechanism 64. A loading station and a loading buffer station are provided on the loading station. A supporting conveying roller group 4 is provided on the loading station. A support platform 7 for conveniently supporting the material frame 2 is provided on the loading buffer station of the loading rack 1. Each transfer slide 62 is synchronously driven by a horizontal transfer power device 63 to slide back and forth synchronously between the loading station and the loading temporary storage position.

[0021] The transfer device 6 in this embodiment can be used in conjunction with the pipe sawing machine 3. Of course, the sawing machine 3 can also be replaced with a machining machine for other pipes or bars.

[0022] In this embodiment, the transfer frame 61 preferably includes a plurality of vertical poles 611 and a plurality of horizontal beams 612. Each vertical pole 611 is fixed to one side of the loading rack 1 and arranged in a row. Each horizontal beam 612 is arranged above the vertical pole 611 and spans the loading station and the loading buffer station. Each horizontal beam 612 is provided with a horizontal guide rail 614. The transfer slide 62 is slidably mounted on the horizontal guide rail 614. A diagonal brace 613 is provided between the horizontal beam 612 and the vertical pole 611. In this embodiment, the loading rack 1 is a frame structure, and the support platform 7 is provided with a support roller group that facilitates the longitudinal movement of the material frame 2.

[0023] In this embodiment, a clamping mechanism 5 is provided downstream of the supporting conveying roller group 4 on the loading rack 1 to facilitate the longitudinal clamping of the pipe, wherein the clamping mechanism 5 includes a clamping slide longitudinally slidably installed on the loading rack 1, and the clamping slide is driven by a clamping power device to slide along the length direction of the pipe or rod, and a clamping fixture for clamping the pipe or rod is installed on the clamping slide. In this embodiment, the clamping fixture includes a fixed chuck and a sliding chuck, and the sliding chuck is driven by a clamping power device. The clamping power device can preferably be a cylinder, and the clamping power device can drive the clamping slide to slide through a motor and a screw nut mechanism. Of course, the clamping power device can also be driven by other transmission methods, such as a motor and a rack and pinion mechanism.

[0024] The link lifting mechanism 64 includes a first upper link 641 and a second upper link 642, a first intermediate link 643 and a second intermediate link 644, and a first lower link 645 and a second lower link 646. The middle portions of the first intermediate link 643 and the second intermediate link 644 are hinged via an intermediate hinge shaft 648. The upper ends of the first intermediate link 643 and the second intermediate link 644 are hinged to the lower ends of the first upper link 641 and the second upper link 642 respectively via a first upper hinge shaft and a second upper hinge shaft. The upper end of the second upper connecting rod 642 is hinged to the transfer slide 62. The lower ends of the first intermediate connecting rod 643 and the second intermediate connecting rod 644 are hinged to the upper ends of the first lower connecting rod 645 and the second lower connecting rod 646 via the first lower hinge shaft and the second lower hinge shaft, respectively. The lower ends of the first lower connecting rod 645 and the second lower connecting rod 646 are hinged to each other and connected to the magnetic block 65 or the transfer fixture. The transfer lifting power device 647 is a linear power device installed between the first upper hinge shaft and the second upper hinge shaft. The linear power device can also be driven by a cylinder. In this embodiment, the linear power device is a cylinder fixed to a cylinder seat, which is rotatably installed on the first upper hinge shaft or the second upper hinge shaft. The corresponding piston rod end of the cylinder is mounted on the second upper hinge shaft or the first upper hinge shaft through a connecting sleeve 619. In this way, both ends of the cylinder can be flexibly connected, thereby reducing errors and ensuring smooth opening and closing between the second upper hinge shaft and the first upper hinge shaft.

[0025] When the cylinder drives the first upper hinge shaft and the second upper hinge shaft to move closer together, the magnetic block 65 or the transfer fixture descends. When the cylinder drives the first upper hinge shaft and the second upper hinge shaft to move away from each other, the magnetic block 65 or the transfer fixture ascends. The entire lifting and lowering action does not exceed the height of the transfer slide 62. Therefore, the lifting, transfer, and lowering of pipes or bars can be completed within a limited height space. In this embodiment, the magnetic block 65 can be in the form of an electromagnet to complete the magnetic on and off, making it convenient to pick up or put down pipes (bars), and the transfer fixture can also be a pneumatic fixture currently on the market to clamp the pipe and transfer it to the support and conveying roller group 4.

[0026] And as Figure 3 As shown, the horizontal transfer power device 63 includes a transfer motor and a chain transmission mechanism. The chain transmission mechanism includes two mounting rods 631 that are rotatably mounted on the transfer frame 61 and extend longitudinally. The two mounting rods 631 are arranged in parallel. Multiple sets of sprocket groups are fixed on the two mounting rods 631. A circulating chain 632 is installed between each set of sprocket groups. One of the mounting rods 631 is connected to the output shaft of the transfer motor. Each circulating chain 632 is fixed to the corresponding transfer slide 62 and drives the transfer slide 62 to slide in both directions through the forward and reverse operation of the circulating chain 632.

[0027] The working principle of this embodiment is: the transfer device 6 together with the loading rack 1 can be placed under the vertical warehouse for storing the material frame 2. Since the height occupied by the magnetic block 65 or the pneumatic clamp of the transfer device 6 during lifting and lowering is relatively low, the height of the vertical warehouse is relatively small, and more space can be used to store the material frame 2. The transfer device 6 uses the horizontal sliding of the transfer slide 62 to switch the work station, which is convenient for the magnetic block 65 or the transfer clamp to absorb or clamp the pipe, and also convenient for releasing the pipe. The whole structure is smooth and reasonable, occupies little space, and has accurate movement, which can meet the requirements of automated transfer of pipes or bars.

[0028] The above-described embodiments are merely descriptions of preferred implementations of the present invention and are not intended to limit the scope of the present invention. Various modifications and alterations to the technical solutions of the present invention without departing from the spirit of the present invention shall fall within the scope of protection defined by the claims of the present invention.
