Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of high-temperature copper pipe conveying, in particular to a high-temperature copper body material conveying device. BACKGROUND

[0002] The copper pipe obtained by hot extrusion process through a hot extrusion furnace needs to be sent to the destination in time to ensure that the next batch of copper pipe extrusion can be carried out smoothly. Usually, a transmission roller is arranged at the outlet position of the hot extrusion furnace, and the friction force between the high-temperature copper pipe and the transmission roller is used as power to realize friction driving to drive the high-temperature copper pipe to the destination.

[0003] However, the surface hardness of the just hot extrusion formed copper pipe is very small, and the transmission roller needs to produce friction force through line contact with certain contact stress, so as to drive the copper pipe to be conveyed. Larger contact stress is easy to cause damage to the surface of the copper pipe, and the transmission roller is easy to cause the extruded high-temperature copper pipe to be serpentine bent. At present, the main countermeasures are to reduce the speed of the transmission roller, reduce the surface roughness of the transmission roller, wait for the copper pipe to be lowered to a certain temperature at the furnace opening before conveying, or take surface treatment measures after the surface damage occurs.

[0004] The above information disclosed in the background section is only used to strengthen the understanding of the background of the present disclosure, so it can include information that does not constitute prior art known to those of ordinary skill in the art. SUMMARY

[0007] When the slider is driven by the non-standard chain from the inclined state to the state of being perpendicular to the two top dies, the slider is still in the semicircular groove, the clamping piece is parallel to the copper pipe and does not contact the copper pipe; when the slider is driven by the non-standard chain to move into the rectangular groove at the same horizontal speed as the copper pipe, the slider is in surface contact with the outer peripheral surface of the copper pipe.

[0010] Preferably, the slider further comprises a guide wheel rotationally installed at an end of the guide rod and rolling in the slide groove, and the slide rod has a rectangular cross section.

[0011] Preferably, a transmission shaft is fixedly installed in the sprocket, one end of the transmission shaft is rotationally connected with the top die, and the other end is rotationally connected with the bottom die, one of the transmission shafts on the top die penetrates the bottom die, a transmission wheel is fixedly installed at one end of the transmission shaft penetrating the bottom die, and the two transmission wheels have opposite rotation directions.

[0012] Preferably, the clamping piece comprises a long rod fixedly connected with an end of the slide rod, and a groove is formed in a side of the long rod away from the slide rod, and the groove cooperates with the outer peripheral surface of the copper pipe.

[0013] Preferably, when the clamping piece is in initial contact with the outer peripheral surface of the copper pipe, the two clamping pieces are symmetrically distributed on both sides of the copper pipe.

Detailed Implementation

[0029] To enable those skilled in the art to better understand the technical solutions in this application, the technical solutions in the embodiments of this application will be clearly and completely described below. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0030] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0031] This invention provides, for example Figures 1-6 The device shown is a high-temperature copper material conveying device used to convey a high-temperature copper tube 1. The copper tube 1, which is newly hot-extruded, has a low surface hardness. Existing roller drives, due to line contact, require high contact stress to meet the frictional force needed for conveying the copper tube 1, which can lead to surface damage and serpentine bending. Therefore, we designed a conveying system that makes surface contact with the copper tube 1, thus requiring less contact stress to meet the necessary frictional force for conveying the copper tube 1. Figure 3 As shown, the conveying system mainly includes a bottom mold 2, on which two top molds 3 are provided. A first positioning plate 11 is fixedly installed on both sides of the top mold 3. A second positioning plate 12 that cooperates with the first positioning plate 11 is fixedly installed on the bottom mold 2. A connecting seat 13 is fixedly installed on the side of the second positioning plate 12 close to the first positioning plate 11. A countersunk bolt 14 that is threadedly connected to the connecting seat 13 passes through the first positioning plate 11. By unscrewing and tightening the countersunk bolt 14, the top mold 3 and the bottom mold 2 can be detachably connected.

[0032] like Figure 3As shown, the two top dies 3 are each provided with a sliding groove 4 composed of a rectangular groove 4a and two semicircular grooves 4b, the bottom die 2 is also provided with two sliding grooves 4 cooperating with the sliding grooves 4 of the top dies 3, the two top dies 3 and the bottom die 2 are each rotatably provided with two transmission shafts 9, one of the transmission shafts 9 of the top die 3 penetrates the bottom die 2 and is fixedly provided with a transmission wheel 10 at the end, the transmission shaft 9 is fixedly provided with a sprocket wheel 7, the two sprocket wheels 7 are jointly meshed with a tensioned non-standard chain 6, the non-standard chain 6 includes an inner chain plate 6a, an outer chain plate 6b, a pin shaft 6c, a roller 6d, and a connecting plate 6e fixedly provided on the outer chain plate 6b, the inner chain plate 6a and the outer chain plate 6b are rotatably connected through the pin shaft 6c, the roller 6d is installed on the pin shaft 6c, the width of the connecting plate 6e is greater than the length of the pin shaft 6c, a mounting plate 5a is detachably installed on the connecting plate 6e through a threaded fastener 5e, the mounting plate 5a is fixedly provided with a hollow tube 5b away from the connecting plate 6e, the hollow tube 5b is penetrates and slidably connected with a sliding rod 5c away from the connecting plate 6e, the sliding rod 5c is fixedly provided with a vertical guide rod 5d, the end of the guide rod 5d is inserted into the sliding groove 4, and the end of the guide rod 5d is rotatably provided with a guide wheel 5f which is rollingly connected in the sliding groove 4, here, in order to ensure that the sliding rod 5c can only slide in the length direction, the cross section of the sliding rod 5c is rectangular, here, the mounting plate 5a, the hollow tube 5b, the sliding rod 5c, the guide rod 5d, the threaded fastener 5e and the guide wheel 5f constitute a sliding part 5, the end of the sliding rod 5c is fixedly provided with a clamping part 8 composed of a long rod 8a and a groove 8b, the groove 8b matches the outer circumferential surface of the copper pipe 1; in this way, when the two transmission wheels 10 rotate in opposite directions, they will drive the transmission shafts 9 to rotate, the transmission shafts 9 will drive the sprocket wheels 7 to rotate, the sprocket wheels 7 will drive the non-standard chain 6 to move through meshing, the non-standard chain 6 will drive the mounting plate 5a through the connecting plate 6e, the mounting plate 5a will drive the sliding rod 5c through the hollow tube 5b, here, the non-standard chain 6 is in a tensioned state, the sliding rod 5c is always perpendicular to the non-standard chain 6, and the sliding rod 5c will drive the clamping part 8 to move; although the clamping parts 8 on the two top dies 3 which are relatively and parallel distributed on both sides of the copper pipe 1 will indeed produce surface contact when they contact the surface of the copper pipe 1 to drive the copper pipe 1 to move and be conveyed, due to the length of the clamping part 8, in the process of the clamping part 8 moving on the chain from being inclined to the two top dies 3 to being perpendicular to the two top dies 3, one end of the clamping part 8 will first contact and press the surface of the copper pipe 1, and then gradually the whole clamping part 8 will produce surface contact, which will cause local contact stress to be relatively large, generate excessive friction force to damage the surface of the copper pipe 1, and only shorten the length of the clamping part 8 to change from surface contact to line contact, which cannot maintain a relatively large contact area;

[0033] To this end, the distance between the central axes of the two sprockets 7 is set to be greater than the distance between the centers of the two semicircular grooves 4b, so that when the hollow tube 5b is moved by the chain, the guide rod 5d on the slide rod 5c carried by the hollow tube 5b is still in the semicircular groove 4b when the hollow tube 5b is tilted from being inclined to being perpendicular to the two top dies 3. At this time, the clamping piece 8 has already been parallel to the copper pipe 1, but because the guide rod 5d is still in the semicircular groove 4b, the clamping piece 8 will have a certain distance from the copper pipe 1. Then the non-standard sprocket 7 moves the guide rod 5d from the semicircular groove 4b to the rectangular groove 4a, so that the clamping piece 8 contacts the copper pipe 1 at the same horizontal moving speed, thereby generating a contact surface friction to move the copper pipe 1 for conveying.

[0034] It is important to note that the construction and arrangement of the application shown in the various exemplary embodiments is illustrative only. Although only a few embodiments have been described in detail in this disclosure, those skilled in the art who review this disclosure will readily appreciate that many modifications are possible (e.g., variations in sizes, dimensions, structures, shapes and proportions of the various elements, values of parameters, mounting arrangements, use of materials, colors, orientations, etc.) without materially departing from the novel teachings and advantages of the subject matter described in the application.
