Description

Technical Field

[0001] The present invention relates to the technical field of pipe cutting, and in particular to a pipe cutting processing device and a processing method. Background Art

[0002] The condenser is an important component in refrigeration systems such as air conditioning, refrigeration, and cold storage, and is mainly used to transmit refrigerant. Its function is to transfer the heat absorbed during the evaporation process in the evaporator and the heat generated during the compression process in the compressor to the condenser through cooling, thereby completing the cooling of the air or water. Therefore, the condenser plays a very important role in the refrigeration system. Based on different usage scenarios, the arrangement and layout of the condenser are also different. In actual application, the turning elbow is an important component in the condensing pipe system. It allows the fluid to change the flow direction at a specific angle (such as 90 degrees, 180 degrees) in the pipe to meet the process requirements or spatial layout requirements; according to different angles, the turning elbow can be divided into multiple types, such as 90-degree turning elbows and 180-degree turning elbows (please refer to the attached figure in the instruction manual) Figure 1 ).

[0003] Moulds play a vital role in the manufacture of pipe fittings, especially steering tubes. The use of moulds can ensure that pipe fittings have high precision and consistency, while improving production efficiency; in the prior art, in order to reduce production costs, a mould is usually used to manufacture 180-degree steering tubes, and then a cutting device is used to cut a group of 180-degree steering tubes into two groups of 90-degree steering tubes. In the actual cutting process, since the 180-degree steering tube is semicircular, the operator needs to find the midpoint of the bend (i.e. the 90-degree position), which is the cutting position, and then mark the cutting line. At the midpoint of the bend, draw a cutting line perpendicular to the axis of the original pipe, ensuring that the cutting line divides the semicircle in half, so that the length of each arc segment is one-quarter of a circle (corresponding to 90 degrees), and then cut;

[0004] However, this cutting method has the following disadvantages: First, during the cutting process, due to the action of the cutting knife, the pipe is prone to deflection or movement, which makes it impossible to achieve the effect of bisecting the semicircle; secondly, this manual line drawing and positioning method is not suitable for mass production, has low efficiency, and requires operators to manually load the materials one by one. Due to the presence of the cutting knife, there are also certain safety hazards. Summary of the invention

[0028] The steering tube is cut by a cutting module arranged on a cutting table, so as to cut a group of 180-degree tubes into two groups of 90-degree tubes.

[0029] Beneficial effects of the present invention:

[0030] (1) The present invention first places a plurality of groups of steering tubes in a stacked manner on a positioning table, and positions each steering tube by a positioning module so that the projection positions of each steering tube on the positioning table remain consistent. Then, the steering tubes are loaded onto a cutting table one by one by a loading module arranged on the positioning table, and then the steering tubes are cut by a cutting module arranged on the cutting table so as to cut a group of 180-degree tubes into two groups of 90-degree tubes. The present invention can achieve the effects of automatic loading and cutting, and has higher efficiency. It is suitable for mass cutting production of 180-degree tubes, and does not require manual loading, and has higher safety.

[0031] (2) In the initial state of the present invention, the U-shaped push frame is located on the positioning table. When the steering tube is placed on the positioning table, the steering tube is supported by the U-shaped push frame. Due to the existence of the U-shaped push frame, the steering tube will not fall into the feeding gap. When feeding is required, the limiting rod and the clamping plates on both sides are driven by the adjustment mechanism to move synchronously toward the axial direction close to the positioning plate to clamp and position each steering tube. Secondly, the U-shaped push frame is driven by the translation mechanism to move in the direction away from the cutting table to pull the U-shaped push frame out of the feeding gap. At this time, the limiting rod and the clamping plates on both sides are driven by the adjustment mechanism to move synchronously toward the axial direction close to the positioning plate to clamp and position each steering tube. The plate moves synchronously in the direction away from the axis of the positioning plate, so that the steering tube at the bottom can fall into the feeding gap under the action of gravity, and then the adjustment mechanism drives the limit rod and the clamping plate again to clamp and position the other steering tubes except the feeding gap. Finally, the U-shaped push frame is driven toward the cutting table by the translation mechanism to push the U-shaped push frame in the feeding gap to the cutting position on the cutting table. This reciprocating movement can achieve the effect of loading one by one. During the loading process, the push column is stuck on both sides of the steering tube to avoid the steering tube from being deflected during the translation process, and the stability is higher.

[0032] (3) In the present invention, when the translation mechanism drives the U-shaped push frame to be pulled out from the feeding gap, the push rod drives the pull rod to move synchronously through the limit frame. When the pull rod contacts the stop rod, as the pull rod continues to move, the movable seat can be pushed to rotate on the guide shaft. Since the guide ring is clamped with the clamping groove through the clamping seat, the guide ring will not rotate synchronously. The torsion spring can generate elastic force. The movable seat drives the second protrusion to clamp and fix the first protrusion through the L-shaped clamping plate, so that the rack will not be reset under the action of the elastic force. When the pull rod continues to move, it can push the rack to separate from the arc-shaped teeth. The positioning frame pushes the guide seat to slide on the guide rod to compress the second spring. At this time, the steering tube is not clamped by the limit rod and the clamping plate and can fall freely. Correspondingly, when the translation mechanism pushes the U-shaped push frame to reset to the feeding gap, the torsion spring can drive the movable seat and the stop rod to automatically reset.

DETAILED DESCRIPTION

[0047] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0048] Example 1

[0049] See also Figure 2-Figure 3 As shown, the present invention is a pipe cutting and processing device, comprising a positioning platform 1, on which a positioning module for positioning a plurality of steering tubes 2 is provided; specifically, in this embodiment, a plurality of 180-degree steering tubes 2 to be cut can be stacked on the surface of the positioning platform 1 in a stacking manner, and then each steering tube 2 is positioned by the positioning module, so that the projection position of each steering tube 2 on the positioning platform 1 is kept consistent;

[0050] On one side of the positioning table 1, a cutting table 101 is also arranged. Among them, a feeding module is also arranged on the positioning table 1, and the feeding module is used to feed the positioned steering pipes 2 onto the cutting table 101 one by one;

[0051] A cutting module is arranged on the cutting table 101, and the cutting module is used to cut the steering pipe 2;

[0052] It can be explained that in this embodiment, several groups of steering pipes 2 are stacked on the positioning table 1, and each steering pipe 2 is positioned by the positioning module so that the projection positions of each steering pipe 2 on the positioning table 1 are kept consistent. Secondly, the steering pipes 2 are fed onto the cutting table 101 one by one through the feeding module arranged on the positioning table 1. Then, the steering pipes 2 are cut by the cutting module arranged on the cutting table 101 to cut a group of 180-degree pipes into two groups of 90-degree pipes. This embodiment can achieve the effects of automatic feeding and cutting, with higher efficiency, is suitable for batch cutting production of 180-degree pipes, and does not require manual feeding, so the safety is higher.

[0053] Embodiment 2

[0054] On the basis of Embodiment 1, please refer to Figure 2-Figure 5 , the positioning module includes a positioning disk 4 rotatably arranged on the positioning table 1. On both sides of the positioning disk 4, clamping plates 202 for clamping the outer sides of the pipe orifices of the steering pipe 2 are symmetrically arranged respectively. On one side of the two clamping plates 202 close to each other, a baffle 203 for abutting against the pipe orifice of the steering pipe 2 is vertically and fixedly arranged. Among them, the two clamping plates 202 are connected to an adjusting mechanism, and the adjusting mechanism is used to drive the two clamping plates 202 to approach or move away from the axis direction of the positioning disk 4; it can be explained that when several groups of stacked steering pipes 2 are placed on the positioning table 1 in this embodiment, the two pipe orifices of the steering pipe 2 are respectively abutted against the baffle 203. At the same time, the adjusting mechanism is used to drive the two clamping plates 202 to synchronously approach the axis direction of the positioning disk 4 to realize the positioning and clamping of the steering pipe 2. Correspondingly, the clamping plates 202 and the baffle 203 in this embodiment both have a certain height, so that multiple groups of stacked steering pipes 2 can be positioned and clamped. The specific height is not limited as long as the requirement for positioning and clamping multiple groups of stacked steering pipes 2 can be met.

[0055] In this embodiment, please refer to Figure 5A limiting rod 201 is also arranged between the positioning disk 4 and the positioning platform 1, and the limiting rod 201 is arranged on a side away from the cutting platform 101, wherein the limiting rod 201 is connected to an adjusting mechanism, and the adjusting mechanism is used to drive the limiting rod 201 and the clamping plates 202 on both sides to synchronously move toward or away from the axis of the positioning disk 4, and the spacing between the limiting rod 201 and the clamping plates 202 on both sides and the axis of the positioning disk 4 is kept consistent; it can be explained that before positioning the steering tube 2, the present embodiment first drives the limiting rod 201 and the clamping plates 202 on both sides to move synchronously toward the axis away from the positioning disk 4 through the adjusting mechanism, so as to facilitate After the steering tubes 2 are stacked, the operator places them in the space formed by the limit rod 201 and the clamping plates 202 on both sides. After the placement is completed, the present embodiment drives the limit rod 201 and the clamping plates 202 on both sides to move synchronously toward the axial direction close to the positioning plate 4 through the adjustment mechanism. During the movement, the limit rod 201 can push the pipe mouth of each steering tube 2 to abut against the baffle 203, and the pipe wall outside the pipe mouth abuts against the clamping plate 202. At the same time, based on the clamping effect of the clamping plates 202 on both sides, the limit rod 201 abuts against the pipe wall at the center point of the steering tube 2, thereby achieving the effect of three-point positioning and clamping of the steering tube 2.

[0056] As a further solution of this embodiment, please refer to Figure 2 and Figure 5 , the bottom of the clamping plates 202 on both sides slides and fits with the positioning table 1, and there is a feeding gap between the limit rod 201 and the baffle plate 203 and the positioning table 1, and the height of the feeding gap is only enough for one group of steering tubes 2 to pass through; it can be explained that in this embodiment, when the steering tube 2 is fed to the cutting table 101, the limit rod 201 and the clamping plates 202 on both sides are driven by the adjustment mechanism to move synchronously in the axial direction away from the positioning disk 4, so that the limit rod 201 and the clamping plates 202 lose their clamping effect on the steering tube 2, so that the steering tube 2 at the bottom can fall into the feeding gap under the action of gravity, and then the limit rod 201 and the clamping plates 202 on both sides are driven by the adjustment mechanism to move synchronously in the axial direction close to the positioning disk 4, so as to clamp and position the other steering tubes 2 except the feeding gap again, and finally the steering tube 2 in the feeding gap is pushed to the cutting position on the cutting table 101 by the feeding module, thereby realizing the effect of automatic feeding, and so on, the effect of feeding one by one can be realized.

[0057] In this embodiment, please refer to Figure 2-Figure 3 as well as Figure 7The feeding module includes a translation mechanism 3 fixedly arranged on the positioning platform 1, and a U-shaped push frame 103 is slidably arranged on one side of the positioning platform 1. The height of the U-shaped push frame 103 corresponds to the height of the steering tube 2, and a push column 104 is fixedly arranged on one end of the U-shaped push frame 103 close to the cutting platform 101, wherein the U-shaped push frame 103 is fixed to the driving end of the translation mechanism 3 through the push rod 102; it can be explained that in the initial state, the U-shaped push frame 103 is located on the positioning platform 1. When the steering tube is placed on the positioning platform 1, the steering tube 2 is supported by the U-shaped push frame 103. Due to the existence of the U-shaped push frame 103, the steering tube 2 will not fall into the feeding gap. When feeding is required, the limiting rod 201 and the clamping plates 202 on both sides are driven by the adjustment mechanism to move synchronously toward the axial direction close to the positioning disk 4 to clamp and position each steering tube 2, and then the translation mechanism is used. 3 drives the U-shaped push frame 103 to move in the direction away from the cutting table 101, so as to draw the U-shaped push frame 103 out of the feeding gap. At this time, the limiting rod 201 and the clamping plates 202 on both sides are driven by the adjustment mechanism to move synchronously in the axial direction away from the positioning plate 4, so that the steering tube 2 located at the bottom can fall into the feeding gap under the action of gravity, and then the adjustment mechanism drives the limiting rod 201 and the clamping plates 202 again to clamp and position the other steering tubes 2 except the feeding gap again, and finally the U-shaped push frame 103 is driven by the translation mechanism 3 to move toward the cutting table 101, so as to push the U-shaped push frame 103 in the feeding gap to the cutting position on the cutting table 101, and the effect of feeding one by one can be achieved by reciprocating in this way. During the feeding process, the push column 104 is stuck on both sides of the steering tube 2 to avoid the steering tube 2 from being deflected during the translation process, and the stability is higher.

[0058] It should be noted that the translation mechanism 3 of this embodiment can adopt a screw nut transmission mechanism or a synchronous belt transmission mechanism, which is not limited in this embodiment, so long as it can drive the U-shaped push frame 103 to reciprocate linearly in the feeding gap.

[0059] Further, in order to improve stability during the loading process, in this embodiment, please refer to Figure 3 A partition plate 205 is fixedly arranged on one side of the clamping plate 202 close to the cutting table 101, and a limit plate 206 is vertically fixedly arranged on the upper side where the two side partition plates 205 are close to each other; it can be explained that in the present embodiment, during the process of pushing the steering tube 2 out of the feeding gap, the movement of the steering tube 2 is further guided by the two side partition plates 205 to avoid the phenomenon of deflection. At the same time, by setting the limit plate 206, the upper part of the steering tube 2 can be limited to avoid the steering tube 2 from tilting during cutting.

[0060] In this embodiment, please refer to Figure 2-Figure 5The adjustment mechanism includes an adjustment plate 204 fixedly arranged on the clamping plate 202 and the limiting rod 201 respectively, a pin 402 is fixedly arranged at the bottom of the other end of the adjustment plate 204, and three groups of inclined grooves 401 for embedding the pin 402 are correspondingly opened on the positioning plate 4, and the inclined grooves 401 are inclined from the near axis end to the far axis end. The positioning plate 4 is rotatably arranged at the bottom of the limiting plate 404, and the limiting plate 404 is fixed to the translation mechanism 3 through the connecting rod 302 and the connecting frame 301. The limiting plate 404 is correspondingly fixed with three groups of adjusting plates 2 04, a guide plate 405 corresponding to the guide plate 405 is provided with a slide groove 406, and a guide shaft 403 fixed to the adjustment plate 204 is slidably embedded in the slide groove 406; it can be explained that when the limit rod 201 and the clamping plate 202 are driven to move synchronously, the pin shaft 402 can synchronously drive the adjustment plate 204 and the guide shaft 403 to move along the slide groove 406 under the limiting effect of the inclined groove 401 by rotating the positioning plate 4, and the adjustment plate 204 can drive the limit rod 201 and the clamping plate 202 to gather or spread synchronously.

[0061] Accordingly, in this embodiment, reference may be made to Figure 2 , Figure 5 as well as Figure 8 , the positioning plate 4 is fixedly provided with an arc-shaped tooth 407 on one side close to the limiting rod 201, and the arc-shaped tooth 407 is meshed with the rack 7, wherein a positioning frame 707 is provided on the positioning platform 1, and the positioning frame 707 is fixedly provided with a positioning rod 705 on one side close to the rack 7, and a sliding seat 704 fixed to the rack 7 is provided on the positioning rod 705, and a first spring 706 is provided on the positioning rod 705, and one end of the first spring 706 is fixed to the positioning frame 707, and the other end is fixed to the sliding seat 704; it can be explained that in the initial state of this embodiment, the limiting rod 201 and the clamping plate 202 are axially spaced from the positioning plate 4 The spacing between the centers is the smallest. When the steering tube 2 needs to be placed, the operator drives the positioning plate 4 to rotate by sliding the rack 7, and the rack 7 is meshed with the arc-shaped teeth 407 to drive the limiting rod 201 and the clamping plate 202 to spread. At this time, the first spring 706 is in a contracted state and generates elastic force. After the steering tube 2 is placed, based on the elastic force of the first spring 706, the rack 7 can be pushed to slide to the initial position until the limiting rod 201 and the clamping plate 202 clamp and position the steering tube 2. At this time, the first spring 706 has not been completely reset to ensure that a clamping force can always be given to the steering tube 2.

[0062] It should also be noted that, in this embodiment, by adjusting the rotation angle of the positioning plate 4, the steering tubes 2 of different sizes can be positioned and clamped, and the application range is wider.

[0063] See also Figure 2-Figure 3 , Figure 7-Figure 8 as well as Fig.12When the limit rod 201 and the clamping plate 202 need to be adjusted to diffuse with each other, as a further solution of this embodiment, a guide rod 709 is fixedly arranged on the positioning platform 1, and a guide seat 708 fixed to the positioning frame 707 is provided on the guide rod 709. A second spring 710 is provided on the guide rod 709, and one end of the second spring 710 is fixed to the guide seat 708, and the other end is fixed to the end of the guide rod 709.

The movable seat 702 is fixed A blocking rod 703 is arranged, and the blocking rods 703 on both sides are respectively located on both sides of the adjustment plate 204. A guide ring 715 slidably connected to the guide shaft 701 is arranged between the two groups of movable seats 702. A card slot 716 is provided on the guide shaft 701. A card seat 717 slidably engaged with the card slot 716 is fixedly arranged on the inner side of the guide ring 715. The two ends of the guide ring 715 are respectively connected to the movable seat 702 through a torsion spring 712. A plurality of groups of first protrusions 711 are evenly arranged on a side wall of the rack 7 close to the limit rod 201. The movable seat 702 closes to the limit rod 20 1 is fixedly arranged on one side of the U-shaped card plate 713, and a plurality of groups of second protrusions 714 that are engaged with the first protrusions 711 are evenly arranged on the side of the bottom of the L-shaped card plate 713 close to the rack 7, wherein a limit frame 105 is fixedly arranged on the push rod 102, and two sides of the end of the limit frame 105 are respectively and vertically fixedly arranged with pull rods 107; it can be explained that when the translation mechanism 3 drives the U-shaped push frame 103 to be pulled out of the feeding gap, the push rod 102 drives the pull rod 107 to move synchronously through the limit frame 105, and when the pull rod 107 and the stop rod When the pull rod 107 contacts the guide shaft 703, as the pull rod 107 continues to move, the movable seat 702 can be pushed to rotate on the guide shaft 701. Since the guide ring 715 is clamped with the clamping groove 716 through the clamping seat 717, the guide ring 715 will not rotate synchronously. The torsion spring 712 can generate elastic force, and the movable seat 702 drives the second protrusion 714 to clamp and fix the first protrusion 711 through the L-shaped clamping plate 713, so that the rack 7 will not be reset under the action of the elastic force. When the pull rod 107 continues to move, the rack 7 can be pushed to separate from the arc-shaped tooth 407 (see Fig. 9 ), the positioning frame 707 pushes the guide seat 708 to slide on the guide rod 709 to compress the second spring 710. At this time, the steering tube 2 is not clamped by the limiting rod 201 and the clamping plate 202 and can fall freely. Correspondingly, when the translation mechanism 3 pushes the U-shaped push frame 103 to return to the upper material gap, the torsion spring 712 can drive the movable seat 702 and the blocking rod 703 to automatically return to their original position.

[0064] In addition, a reserved slot 106 is provided on the limiting frame 105 to avoid interference with the connecting rod 302 .

[0065] See also Figure 3-Figure 6The cutting module includes a cutting bracket 5 fixed on the cutting table 101, and a lifting cylinder 501 is fixedly arranged on the cutting bracket 5. The driving end of the lifting cylinder 501 is fixed to the lifting plate 502, and a cutting device 503 is fixedly arranged on the lifting plate 502 close to the side of the positioning table 1, and the cutting knife of the cutting device 503 corresponds to the axial position of the limiting rod 201; specifically, when the feeding module feeds the steering tube 2 to the cutting position, the lifting cylinder 501 drives the cutting device 503 to descend so as to cut the steering tube 2 with the cutting knife. In the feeding process of this embodiment, the position of the center point of the steering tube 2 always corresponds to the position of the limiting rod 201 and the cutting knife, so that when cutting, the 180-degree steering tube 2 can be divided into two 90-degree steering tubes 2.

[0066] In addition, guide grooves 505 are provided on the positioning platform 1 and the cutting platform 101 at positions corresponding to the cutting device 503 to facilitate cutting by the cutting knife.

[0067] As a further solution of this embodiment, please refer to Figure 2 and Figure 6 , one end of the cutting table 101 close to the positioning table 1 is rotatably connected to the support frame 602 through a rotating shaft 601, a bearing rod 603 is provided at the bottom of the other side of the cutting table 101, and both ends of the bearing rod 603 are respectively fixed to the L-shaped support 604, and a support plate 606 is fixedly arranged at the end of the cutting bracket 5 away from the positioning table 1, and a guide column 6 fixed to the L-shaped support 604 is slidably arranged in the support plate 606, and a third spring 607 is provided on the guide column 6, one end of the third spring 607 is fixed to the bottom end of the guide column 6, and the other end is fixed to the support plate 606, and a lifting rod 605 is fixedly arranged on the L-shaped support 604, and a pressing plate 504 is fixedly arranged at the end of the lifting plate 502 away from the cutting device 503, The plate 504 extends to the lifting rod 605; it can be explained that in the initial state, based on the elastic force of the third spring 607, the bearing rod 603 can be supported by the guide column 6 and the L-shaped support 604, so that the cutting table 101 is in a horizontal state. When the cutting is completed, as the lifting cylinder 501 continues to drive the cutting device 503 to descend, the pressing plate 504 can press the lifting rod 605 to descend, so that the bearing rod 603 is synchronously lowered. When the U-shaped push frame 103 is withdrawn, based on the gravity of the steering tube 2 itself, the cutting table 101 can be pressed to deflect, thereby achieving the effect of automatic unloading, without the need for manual unloading, and higher safety (see Fig.10 ).
