[0002] When producing stainless steel composite pipes, a straightening machine is required to straighten the bent parts of the stainless steel composite pipes. During the straightening process, the stainless steel composite pipes are placed on the machine base of the straightening machine, and the bent parts of the stainless steel composite pipes are corrected by pressing down the pressing head above.

[0003] When the existing straightening machine processes stainless steel composite pipes, the loading and unloading of the stainless steel composite pipes need to be carried out manually or by hoisting. The manual handling method not only increases the labor cost but also is time-consuming and laborious. The hoisting method by crane is blocked by the pressing head above the stainless steel composite pipes, which brings inconvenience to the loading and unloading of the stainless steel composite pipes.

[0004] Therefore, it is necessary to improve the straightening machine in the prior art. Content of the Utility Model

[0005] The purpose of the utility model is to overcome the defects existing in the prior art, and provide a straightening machine for stainless steel composite pipes to improve the convenience of loading and unloading of the straightening machine.

[0006] To achieve the above purpose, the specific technical solution of the straightening machine for stainless steel composite pipes of the utility model is as follows:

The supporting and placing mechanism comprises two supporting blocks arranged to slide relatively along a direction perpendicular to the first direction above the roller frame. The horizontal height of the supporting blocks is greater than the horizontal height of the power rollers, and the supporting blocks are configured to support the composite pipes on the power rollers.

[0010] Preferably, the outer diameter of the power roller gradually decreases from both ends to the middle along the radial direction.

[0025] The following combines the accompanying drawings and embodiments to further describe the specific implementation manners of the present utility model. The following embodiments are only used to more clearly illustrate the technical solutions of the present utility model and cannot be used to limit the protection scope of the present utility model.

[0026] "Top surface", "bottom", and "bottom surface" are referenced based on the normal use state of the straightening machine, and are only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or component referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation to the present utility model.

[0027] As Figure 2-4 shown, a straightening machine for stainless steel composite pipes includes a machine base 1 and a press head 2 that is vertically arranged above the machine base 1. It also includes a main roller path 4 that is horizontally arranged on the top surface of the machine base 1 along a first direction. The main roller path 4 includes a roller frame 402 fixedly connected to the machine base 1 and a plurality of power rollers 401 arranged at equal intervals along the first direction on the top surface of the roller frame 402; a supporting and placing mechanism 3, with at least two arranged on the top surface of the machine base 1. The supporting and placing mechanism 3 includes two supporting blocks 305 that are relatively slidably arranged above the roller frame 402 along a direction perpendicular to the first direction. The horizontal height of the supporting block 305 is greater than the horizontal height of the power roller 401, and the supporting block 305 is configured to support the composite pipe on the power roller 401.

[0028] The above straightening machine is applicable to the straightening operation of stainless steel composite pipes. The power rollers 401 installed on the roller rack 402 are equipped with independent drive motors, enabling each power roller 401 to independently control its rotation. Thus, through the cooperation of multiple power rollers 401, the stainless steel composite pipe can be driven to move on the main roller path 4, realizing the transportation of the stainless steel composite pipe. At the position of the pressing head 2, a sensor is also provided to detect the position of the stainless steel pipe and the bent part of the stainless steel pipe. When the stainless steel composite pipe moves on the main roller path 4 and the sensor detects the bent part of the stainless steel composite pipe, the main roller path 4 stops transporting. The two supporting blocks 305 move closer to each other to the lower part of the stainless steel composite pipe, thereby lifting the stainless steel composite pipe from the main roller path 4. At the same time, the ends of the stainless steel composite pipe are supported by the supporting blocks 305, and pressure is applied to the bent part of the stainless steel composite pipe by pressing down the pressing head 2, realizing the straightening operation of the stainless steel composite pipe. After straightening, the two supporting blocks 305 move away from each other and move away from the lower part of the stainless steel composite pipe, then the stainless steel composite pipe drops onto the main roller path 4. The straightened stainless steel composite pipe is moved away from directly below the pressing head 2 through the main roller path 4, and then the stainless steel composite pipe is lifted away by hoisting, avoiding the interference of the pressing head during the loading and unloading of the stainless steel composite pipe, and improving the convenience of the loading and unloading of the straightening machine.

[0029] In this straightening machine, multiple stainless steel composite pipes can also be placed on the main roller path 4 at the same time, so that a loading area, a straightening area, and an unloading area can be divided on the main roller path 4, enabling the loading and unloading and straightening operations of the stainless steel composite pipes to be carried out simultaneously, thereby improving the production efficiency of the straightening machine.

[0030] A further improvement is that, as Figure 3 shown, the outer diameter of the power roller 401 gradually decreases from both ends to the middle along the radial direction. The structure of the power roller 401 in the above straightening machine can play a role in limiting the stainless steel composite pipe, preventing the stainless steel composite pipe from rolling off the main roller path 4.

[0031] A further improvement is that, as Figure 3-5 shown, the horizontal height of the top surfaces of the two supporting blocks 305 gradually increases from the closer end to the farther end along the first direction, and the minimum horizontal height of the supporting blocks 305 is greater than or equal to the maximum horizontal height of the power roller 401. In the above straightening machine, the top surfaces of the two supporting blocks 305 are both inclined planes and can be combined into a V-shaped structure. The stainless steel composite pipe is located inside the V-shaped structure, which can play a role in limiting the stainless steel composite pipe, improving the stability of the placement of the stainless steel composite pipe during the straightening process, and further improving the straightening accuracy.

[0032] A further improvement is that, as Figure 5As shown, a plurality of guide wheels 306 are evenly distributed along the top surface of the supporting block 305 perpendicular to the first direction. The arrangement of the guide wheels 306 can reduce the friction between the supporting block 305 and the stainless steel composite pipe, thereby reducing the wear on the stainless steel composite pipe. The guide wheels 306 can be provided with motors for driving their rotation, so that the stainless steel composite pipe can be driven to rotate around its own axis by the guide wheels 306, realizing the turning over of the stainless steel composite pipe, and thus the stainless steel composite pipe can be straightened from different sides, improving the straightening effect of the stainless steel composite pipe.

[0033] A further improvement is that the two supporting blocks 305 on the same supporting mechanism 3 are arranged in a staggered manner. When the two staggered supporting blocks 305 move, they can have an overlapping part. When the two supporting blocks 305 move towards each other, the range of the overlapping part becomes larger, and the bottom of the V-shaped structure formed by the top surfaces of the two supporting blocks 305 rises, then the lifting height of the stainless steel composite pipe can be increased; conversely, the lifting stiffness of the stainless steel composite pipe can be reduced. By adjusting the lifting height of the stainless steel composite pipe, it is convenient to straighten the stainless steel composite pipe and improve the convenience of using the straightening machine.

[0034] A further improvement is that, as Figure 3 and 4 shown, a chute 101 is opened on the top surface of the machine base 1 along the first direction. A slide rail 301 extending perpendicular to the first direction is slidably fitted in the chute 101. The supporting block 305 is fixedly connected with a sliding seat 304 slidably fitted with the slide rail 301. An electric push rod 302 for driving the sliding seat 304 to move is arranged on the slide rail 301, and a driving member 102 for driving the slide rail 301 to move is arranged on the machine base 1.

[0035] The two sliding seats 304 are respectively pushed by an electric push rod 302 to move along the slide rail 301. In this way, the two supporting blocks 305 can be controlled to move closer to or away from each other, realizing the lifting and lowering of the stainless steel composite pipe. The driving member 102 includes a lead screw and a motor arranged inside the chute 101. The lead screw is in threaded cooperation with the slide rail, and the motor drives the lead screw to rotate, thereby driving the slide rail 301 to slide along the first direction through the lead screw, so that the interval between the two supporting mechanisms 3 can be adjusted, realizing the support of stainless steel composite pipes of different lengths and improving the practicability of the straightening machine. When the two supporting mechanisms 3 move synchronously, fine adjustment of the stainless steel composite pipe along the axis can also be realized, improving the convenience of using the straightening machine.

[0036] A further improvement is that, as Figure 4 and 5As shown in the figure, limiting through grooves 307 are formed on both sides of the slide rail 301 along its extending direction. The sliding seat 304 has a U-shaped structure, and limiting blocks 303 that are slidably engaged with the limiting through grooves 307 are provided on the inner side walls of both sides of the sliding seat 304. The cooperation between the limiting blocks 303 and the limiting through grooves 307 can improve the connection stability between the slide rail 301 and the supporting block 305, and further improve the operating stability of the straightening machine.

[0037] A further improvement is that, as Figure 1 and 6 shown in the figure, extension roller paths 5 are butted at both ends of the main roller path 4. A guide sleeve 603 is fixedly connected to the extension roller path 5. A vertically arranged guide post 602 is slidably engaged with the guide sleeve 603. The bottom end of the guide post 602 is fixedly connected to a bottom plate 601, and a power member 604 for driving the extension roller path 5 to move up and down is arranged on the bottom plate 601. The extension roller path 5 is butted with the main roller path 4. The extension roller path 5 is also provided with roller frames 402 and power rollers 401 that are the same as those of the main roller path 4. The extension roller path 5 can be connected to the equipment of the previous process or the next process in the production of stainless steel composite pipes to form an assembly line for production, so as to directly convey the stainless steel composite pipes to the straightening machine without manual handling for loading and unloading, improving the production efficiency; when not combined into an assembly line, the power member 604 can be a combination of a lead screw and a motor. The motor drives the lead screw to rotate, so as to drive the extension roller path 5 to move up and down along the guide post 602 through the lead screw. The loading and unloading of the stainless steel composite pipes can be carried out through the up and down movement of the extension roller path 5 without manual handling or hoisting, improving the convenience and production efficiency of using the straightening machine.
