[0042] 34b - Side pressure feeding cylinder 34b. Specific embodiments

[0043] The following further elaborates on the present utility model in detail in conjunction with the description drawings and specific embodiments.

[0044] Referring to the attached Figure 1 to the attached Figure 2 As shown, this embodiment provides a cutting and bending integrated machine 10, including a frame 100. The frame 100 includes opposite ends. According to the processing and conveying direction of the metal sheet or profile 200, one end of the frame 100 is defined as the input end, and the other end of the frame 100 is defined as the output end. The metal sheet or profile 200 is input from the input end and output from the output end.

[0045] Continuing to refer to the attached Figure 1 to the attached Figure 2As shown in the figure, a feeding device 30b, a starting point positioning device 60e, a pair of saw blade cutting devices 40c, an automatic feeding device 50d, and a double-axis automatic bending device 10a are arranged in sequence on the frame 100 along the direction from the input end to the output end. In this way, one end of the metal sheet or profile 200 is driven by the feeding device 30b to move forward for conveying. The starting point positioning device 60e is used to position the starting point of the metal sheet or profile 200. A pair of saw blade cutting devices 40c are used to perform fixed-length cutting on the metal sheet or profile 200. The automatic feeding device is used to continue to convey the metal sheet or profile 200 after the fixed-length cutting is completed, and the double-axis automatic bending device is used to perform bending and forming on it.

[0046] Referring to the appendix Figure 12 and the appendix Figure 14 As shown in the figure, in this embodiment, the feeding device 30b includes a feeding driven wheel 33b, a feeding driving wheel 31b, and a side pressure feeding cylinder 34b. The feeding driving wheel 31b and the feeding driven wheel 33b are installed relatively left and right at the input end of the frame 100. An input port for placing the metal sheet or profile 200 is reserved between the feeding driving wheel 31b and the feeding driven wheel 33b. The feeding driving wheel 31b is rotatably installed on the frame 100, and the feeding driving wheel 31b is driven by a feeding driving device 32b, that is, the feeding driving wheel 31b can rotate horizontally relative to the frame 100 to drive the metal sheet or profile 200 to move forward for conveying.

[0047] The side pressure feeding cylinder 34b is fixedly installed on the frame 100. The piston rod of the side pressure feeding cylinder 34b is connected to the feeding driven wheel 33b through a connecting plate. The side pressure feeding cylinder 34b can push the feeding driven wheel 33b to approach or move away from the other feeding driving wheel 31b.

[0048] In this embodiment, the feeding driving device 32b is arranged above the frame 100. The feeding driving device 32b drives the feeding rotating wheel to rotate through a feeding main transmission shaft 35b. In this embodiment, the feeding driving device 32b adopts a driving transmission structure formed by a synchronous pulley + synchronous belt. The reason for adopting the driving transmission structure of synchronous pulley + synchronous belt in this embodiment is that the automatic feeding device in this embodiment can also adopt the feeding driving device 32b as the power source. And for the feeding device and the automatic feeding device to adopt the same driving power source, the structure of the whole equipment can be made more compact, and the manufacturing cost can also be made lower. It can be understood that the feeding driving device 32b can also adopt other common power driving structures, which is not limited.

[0049] Continue to refer to the appendix Figure 12 and the appendix Figure 14As shown, the starting point positioning device 60e is installed on the inner side of the frame 100 near the feeding device, that is, when the metal sheet or profile 200 is driven forward by the feeding device, the entry end of the metal sheet or profile 200 will cooperate with the starting point positioning device 60e, and the starting point positioning device 60e will resist and contact the input end of the metal sheet or profile 200 so as to calculate the forward moving length of the metal sheet or profile 200.

[0050] In this embodiment, the starting point positioning device 60e includes a positioning pressure cylinder 61e and a positioning baffle 62e. The positioning pressure cylinder 61e is fixedly mounted on the frame 100. The piston rod of the positioning pressure cylinder 61e is fixedly connected to the positioning baffle 62e, and is used to drive the positioning baffle 62e to move telescopically. Before the metal sheet or profile 200 enters the input port of the feeding device, the positioning pressure cylinder 61e pushes the positioning baffle 62e to extend outward, and the positioning baffle moves to the input port of the feeding device, which can block the metal sheet or profile 200 entering the frame 100 from the input port. When the metal sheet or profile 200 enters from the input port of the feeding device, the entry end of the metal sheet or profile 200 will come into contact with the positioning baffle 62e, and the control system will detect that the metal sheet or profile 200 begins to be in the input state. Subsequently, the positioning pressure cylinder 61e drives the positioning baffle 62e to move in the reverse direction, leaving space for the metal sheet or profile 200 to move forward, and the control system can control the moving distance of the metal sheet or profile 200 by controlling the number of revolutions of the feeding driving wheel 31b in the feeding device, thereby laying a foundation for the subsequent fixed-length cutting of the metal sheet or profile 200. It is understandable that the control of the moving distance of the metal sheet or profile 200 can adopt other commonly used control transmission structures, without limitation.

[0051] Combined with reference to Figure 2 , Attachment Figure 12 And attached Figure 13 As shown, in this embodiment, the metal sheet or profile 200 is cut to length by the pair of saw blade cutting devices 40c. At the same time, in order to facilitate the cutting of the metal sheet or profile 200, a guide plate 80g is fixedly installed on one side of the conveying direction of the metal sheet or profile 200 inside the frame 100.

[0052] A pair of saw blade cutting devices 40c are arranged in sequence in the frame 100 along the conveying direction of the metal plate or profile 200. The pair of saw blade cutting devices 40c are arranged opposite to each other, and a conveying channel for the metal plate or profile 200 to pass through is formed between the guide plate 80g and the pair of saw blade cutting devices 40c.

[0053] To prevent shaking during the cutting of metal sheets or profiles 200, which may affect the cutting quality, multiple groups of upper pressing cylinder devices 92k are provided on the material guiding plate 80g. The multiple groups of upper pressing cylinder devices 92k are arranged at intervals along the conveying direction of the metal sheets or profiles 200. Each upper pressing cylinder device 92k includes an upper pressing cylinder fixing seat 923k, an upper pressing cylinder 922k, and a pressing plate 921k. The upper pressing cylinder fixing seat 923k is fixedly installed on the material guiding plate 80g. The upper pressing cylinder 922k is fixedly installed on the upper pressing cylinder fixing seat 923k. The pressing plate 921k is fixedly installed on the piston rod below the upper pressing cylinder 922k. The pressing plate 921k is horizontally arranged above the conveying channel and is used to press tightly against the top of the metal sheets or profiles 200 located in the conveying channel, achieving the effect of straightening the top of the metal sheets or profiles 200 during cutting.

[0054] Refer to the attached Figure 10 and the attached Figure 11 As shown, multiple groups of side pressing cylinder assemblies 70f are arranged at intervals along the conveying direction of the metal sheets or profiles 200 on the material guiding plate 80g, and are used to support the side of the metal sheets or profiles 200 located in the conveying channel that is away from the material guiding plate 80g.

[0055] Specifically, the side pressing cylinder assembly 70f includes a side pressing cylinder 71f, a side pressing cylinder fixing plate 72f, an "L"-shaped side pressing cylinder head 73f, and a side pressing rubber head 74f. The side pressing cylinder 71f is fixedly installed on the side of the material guiding plate 80g away from the conveying channel through the side pressing cylinder fixing plate 72f. The "L"-shaped side pressing cylinder head 73f horizontally passes through the bottom end of the material guiding plate 80g and extends to the other side of the material guiding plate 80g. The "L"-shaped side pressing cylinder head 73f forms a horizontal sliding connection with the material guiding plate 80g. One end of the "L"-shaped side pressing cylinder head 73f is fixedly connected to the side pressing cylinder 71f, and the side pressing rubber head 74f is horizontally installed at the other end of the "L"-shaped side pressing cylinder head 73f. By adopting the "L"-shaped side pressing cylinder head 73f and slidingly installing it at the bottom of the material guiding plate 80g, it is possible to ensure a simple pressing structure while not interfering with the moving path of the metal sheets or profiles 200.

[0056] When the cutting saw blade assembly cuts the metal sheets or profiles 200, the side pressing cylinder 71f pushes the side pressing rubber head 74f to move towards the side close to the material guiding plate 80g, so that the side pressing rubber head 74f fits tightly against the outer surface of the metal sheets or profiles 200, applying a pressing force to make the metal sheets or profiles 200 fit on the material guiding plate 80g. This can prevent the metal sheets or profiles 200 from shaking during the cutting process and ensure the cutting quality.

[0057] Refer to the attached Figure 13As shown, in this embodiment, the saw blade cutting device 40c includes a saw blade cutting assembly 41c. At the bottom end of the saw blade cutting assembly 41c, there is a rotating assembly 42c for driving its rotation. The rotating assembly 42c is vertically slidably mounted on a vertically lifting and fixing seat 43c provided. On the rotating assembly 42c, there is a vertical lifting assembly 46c for driving its vertical lifting movement. The vertical lifting assembly 46c is mounted on a vertically lifting seat connecting plate 45c provided. The vertically lifting seat connecting plate 45c forms a horizontal sliding connection with the frame 100, and the vertically lifting seat connecting plate 45c is connected to a horizontally driving assembly 44c provided.

[0058] By providing a rotating assembly 42c at the bottom end of the saw blade cutting assembly 41c, the saw blade cutting assembly 41c can be horizontally rotated to adjust the horizontal cutting angle. At the same time, since the rotating assembly 42c is mounted on the vertically lifting and fixing seat 43c, and a vertical lifting assembly 46c is mounted at the bottom end of the vertically lifting and fixing seat 43c, the vertical lifting assembly 46c is used to drive the rotating assembly 42c to perform lifting and sliding, so as to realize the lifting adjustment of the cutting position of the saw blade cutting assembly 41c. In addition, since the vertical lifting assembly 46c is mounted on the vertically lifting seat connecting plate 45c, and the vertically lifting seat connecting plate 45c is connected to the horizontally driving assembly 44c, the horizontal movement of the vertically lifting seat connecting plate 45c is driven by the horizontally driving assembly 44c to realize the adjustment of the cutting position of the saw blade cutting assembly 41c in the horizontal direction. With the above structure, through the movement of the saw blade cutting assembly 41c in the horizontal and vertical directions and its horizontal rotation, the saw blade cutting assembly 41c can perform grooving cutting at any angle.

[0059] Refer to the attached Figure 10 and the attached Figure 11 As shown, in order to be able to centrally collect the waste chips generated when the saw blade cutting assembly 41c cuts metal plates or profiles 200, a bottom waste receiving hopper 90h is installed at the bottom of the frame 100. The bottom waste receiving hopper 90h is arranged in a downward inclined manner. The lower end of the bottom waste receiving hopper 90h is provided at the bottom of one end of the frame 100 near the input end. In the saw blade cutting device 40c, there is a waste hopper 91j for receiving the waste generated during cutting. The outlet of the waste hopper 91j is arranged adjacent to the upper part of the bottom waste receiving hopper 90h.

[0060] In this way, when the cutting saw blade assembly cuts the metal plate or profile 200, the waste chips generated during cutting can slide down through the waste hopper 91j and fall into the bottom waste receiving hopper 90h for centralized collection.

[0061] See the attached Figure 3 to the attached Figure 6As shown, the dual-axis automatic bending device 10a in this embodiment includes a pair of bending shafts 100a, a pallet assembly 200a, and a rotary drive assembly 300a.

[0062] The output ends of the pair of bending shafts 100a vertically extend into the workbench 20a and extend outward. Two sets of arc-shaped clearance grooves 21a intersecting at 0-180 degrees are formed on the tabletop of the workbench 20a. The output ends of the pair of bending shafts 100a are respectively matched with the two sets of arc-shaped clearance grooves 21a, that is, the output ends of the bending shafts 100a can rotate relative to the arc-shaped clearance grooves 21a. The input ends of the pair of bending shafts 100a are installed in the pallet assembly 200a through a connecting plate 400a, and the input ends of the pair of bending shafts 100a are rotatably installed on the connecting plate 400a through bearings provided, and the connecting plate 400a is fixedly installed in the pallet assembly 200a.

[0063] Refer to the attached Figure 6 and the attached Figure 7 As shown, the pallet assembly 200a includes a lower pallet 201a, a dual-axis conversion block 202a, a pallet drive device 203a, and a top positioning device 204a. The top end surface of the lower pallet 201a is fixedly connected to the bottom end of the connecting plate 400a. A slide rail and a slide groove are formed between the bottom end of the lower pallet 201a and the top end surface of the dual-axis conversion block 202a, that is, the lower pallet 201a and the dual-axis conversion block 202a can move relative to each other.

[0064] The pallet drive device 203a is installed at one end of the lower pallet 201a and is used to drive the relative movement between the lower pallet 201a and the dual-axis conversion block 202a.

[0065] In this embodiment, the pallet drive device 203a includes a pallet servo motor 2031a. The pallet servo motor 2031a is fixedly installed on a provided motor connection seat 2032a. The motor connection seat 2032a is fixedly installed at one end of the lower pallet 201a. The output end of the pallet servo motor 2031a is fixedly connected to one end of a provided lead screw. The lead screw is arranged between the bottom end surface of the lower pallet 201a and the top end surface of the dual-axis conversion block 202a. A ball screw nut is installed on the lead screw, and the ball screw nut is fixedly connected to the bottom end surface of the lower pallet 201a. In this way, when the pallet servo motor 2031a drives the lead screw to rotate, the lead screw will drive the ball screw nut thereon to move. The moving ball screw nut will then synchronously drive the lower pallet 201a fixedly connected thereto to move, thereby realizing the relative movement between the lower pallet 201a and the dual-axis conversion block 202a. It should be noted here that the pallet drive device 203a can also adopt other common drive mechanisms, such as a cylinder drive mechanism, without limitation.

[0066] The top positioning device 204a is installed at the upper end surface of the connecting plate 400a. There can be a pair of top positioning devices 204a, and the pair of top positioning devices 204a are symmetrically arranged on the opposite sides of the connecting plate 400a. The top positioning device 204a is used to cooperate with the workbench 20a, and the connecting plate 400a can be locked with the workbench 20a through the top positioning device 204a, that is, there is no relative movement between the connecting plate 400a and the workbench 20a.

[0067] Refer to the attached Figure 7 and the attached Figure 10 As shown, in this embodiment, the top positioning device 204a includes a top lifting cylinder 2041a, a top table positioning pin 2043a, and a top guiding flange assembly. The top guiding flange assembly includes a top flange seat 2045a, a top guiding sleeve fixing seat 2042a, and a top guiding sleeve 2044a. The fixing seat 2042a of the top guiding sleeve 2044a is fixedly installed on the top end surface of the lower support plate 201a, the top flange seat 2045a is fixedly installed on the top end surface of the top guiding sleeve fixing seat 2042a. The bottom end of the top table positioning pin 2043a is fixedly connected to the top lifting cylinder 2041a. The top end of the top table positioning pin 2043a vertically passes through the top guiding sleeve fixing seat 2042a and the top flange seat 2045a and extends outwards. The top table positioning pin 2043a forms a sliding connection in the vertical direction with the top guiding sleeve fixing seat 2042a and the top flange seat 2045a. The top guiding sleeve 2044a is sleeved on the outer surface of the top table positioning pin 2043a in the region between the bottom end surface of the top guiding sleeve fixing seat 2042a and the top end surface of the lower support plate 201a. In some embodiments, the top guiding sleeve 2044a is sleeved on the outer surface of the top table positioning pin 2043a through a top copper sleeve provided to improve the wear resistance between the top guiding sleeve 2044a and the top table positioning pin 2043a.

[0068] Refer to the attached Figure 5 and the attached Figure 6 As shown, pin holes 22a are correspondingly arranged on the table surface of the workbench 20a. When it is necessary to adjust the position of the double-axis slider, it is necessary to drive the top table positioning pin 2043a to move upwards by means of the lifting cylinder in the top positioning device 204a, so that the top table positioning pin 2043a extends into the pin hole 22a on the workbench 20a. At this time, the lower support plate 201a is fixed to the workbench 20a as a whole, and there is no relative movement between the two. At this time, the servo motor operates. Since the lower support plate 201a is fixed to the workbench 20a at this time, the double-axis rotating slider can move relative to the lower support plate 201a. The moving double-axis conversion block 202a drives the rotating shaft 301a (described in detail later) connected to its lower part to move, so that the rotating shaft 301a is concentric with one of the bending shafts 100a in the pair of bending shafts 100a.

[0069] Referring to the attached Figure 6 and the attached Figure 8 As shown, in this embodiment, the rotation drive assembly 300a includes a rotating shaft 301a, a slide plate 302a, a slide rail fixing plate 303a, a rotating device 304a, and a bottom positioning device 305a. The top surface of the slide plate 302a is fixed to the bottom end of the double-axis conversion block 202a. The bottom end of the slide plate 302a forms a sliding connection with the top end of the slide rail fixing plate 303a. The sliding direction of the slide plate 302a is parallel to the sliding direction of the lower support plate 201a. The rotating shaft 301a vertically penetrates through the slide plate 302a and the slide rail fixing plate 303a, and the rotating shaft 301a forms a rotating connection with the slide plate 302a and the slide rail fixing plate 303a respectively. The top end of the rotating shaft 301a is fixedly connected to the bottom end of the double-axis conversion block 202a, and the bottom end of the rotating shaft 301a is fixedly connected to the rotating device 304a. The slide plate 302a and the slide rail fixing plate 303a can be locked and connected by the bottom positioning device 305a, and the rotating device 304a is fixedly installed at the bottom end of the slide plate 302a.

[0070] Referring to the attached Figure 8 and the attached Figure 9 As shown, an opening groove 307a is formed on the slide rail fixing plate 303a. The opening direction of the opening groove 307a is parallel to the moving direction of the slide plate 302a. In this way, when the slide plate 302a moves relative to the slide rail fixing plate 303a, the slide plate 302a will synchronously drive the rotating device 304a below it to move, and the setting of the opening groove 307a reserves a space for the movement of the rotating device 304a.

[0071] Continuing to refer to the attached Figure 8 and the attached Figure 9 As shown, in this embodiment, the bottom positioning device 305a can be a pair, and the pair of bottom positioning devices 305a are symmetrically arranged on the opposite sides of the slide rail fixing plate 303a. The bottom positioning device 305a is used to lock the slide plate 302a and the slide rail fixing plate 303a, that is, the slide plate 302a and the slide rail fixing plate 303a cannot move relative to each other.

[0072] In this embodiment, the bottom positioning device 305a includes a bottom lifting cylinder 3051a, a bottom table positioning pin 3053a, a slide flange 306a, and a bottom guide flange assembly. The bottom guide flange assembly includes a bottom flange seat 3055a, a bottom guide sleeve fixing seat 3052a, and a bottom guide sleeve 3054a. The bottom guide sleeve fixing seat 3052a is fixedly installed on the top surface of the slide rail fixing plate 303a. The bottom flange seat 3055a is fixedly installed on the top surface of the bottom guide sleeve fixing seat 3052a. The bottom end of the bottom table positioning pin 3053a is fixedly connected to the bottom lifting cylinder 3051a. The top end of the bottom table positioning pin 3053a vertically passes through the bottom guide sleeve fixing seat 3052a and the bottom flange seat 3055a and extends outward. The bottom table positioning pin 3053a forms a sliding connection in the vertical direction with the bottom guide sleeve fixing seat 3052a and the bottom flange seat 3055a. The bottom guide sleeve 3054a is sleeved on the outer surface of the bottom table positioning pin 3053a in the region between the bottom end surface of the bottom guide sleeve fixing seat 3052a and the top surface of the slide rail fixing plate 303a. The slide flange 306a is fixedly installed on the slide 302a. The slide flange 306a is provided with a slide pin hole that is tightly engaged with the bottom table positioning pin 3053a. A pair of slide flanges 306a is provided on each side of the slide 302a. In this way, by using the cooperation between the bottom table positioning pin 3053a and the slide flanges 306a at different positions, the rotating shaft 301a can be concentrically mated with a pair of bending shafts 100a respectively to meet different bending requirements.

[0073] In some embodiments, the bottom guide sleeve 3054a is sleeved on the outer surface of the bottom table positioning pin 3053a through a provided bottom copper sleeve to improve the wear resistance between the bottom guide sleeve 3054a and the bottom table positioning pin 3053a.

[0074] To better understand the double-axis automatic bending device 10a in this embodiment, the following describes its working principle:

[0075] When bending, the top lifting cylinder 2041a first drives the top table positioning pin 2043a to extend outwards, so that the top table positioning pin 2043a is inserted into the pin hole on the workbench 20a, realizing the fixation of the lower support plate 201a and the workbench 20a as a whole, and no relative movement can occur between the two; Subsequently, the servo motor operates. Since the lower support plate 201a is fixed on the workbench 20a at this time, the double-axis rotating slider can move relative to the lower support plate 201a. The moving double-axis conversion block 202a drives the rotating shaft 301a connected to it below to move, so that the rotating shaft 301a is concentric with one of the bending shafts 100a in the pair of bending shafts 100a; Then the bottom lifting cylinder 3051a drives the bottom table positioning pin 3053a to extend outwards, so that the bottom table positioning pin 3053a is inserted into the slide plate pin hole on the slide plate flange 306a, realizing the fixation between the slide plate 302a and the slide rail fixing plate 303a. At the same time, the top lifting cylinder 2041a drives the top table positioning pin 2043a to retract and reset. Finally, the rotating device 304a drives the rotating shaft 301a to drive the upper double-axis conversion block 202a to rotate, and uses the bending shaft 100a concentric with the rotating shaft 301a at this time to rotate relative to the other bending shaft 100a along the arc-shaped clearance groove 21a on the workbench surface of the workbench 20a, realizing the bending and forming work of the metal plate or profile 200.

[0076] During the above bending process, by using the cooperation between the top positioning device 204a and the support plate driving device 203a, the lower support plate 201a can move reciprocally, so that one of the bending shafts 100a in the double bending shafts 100a is concentric with the lower rotating shaft 301a, and the slide plate 302a and the slide rail fixing plate 303a are locked by the bottom positioning device 305a. In this way, when the rotating device 304a drives the bending shaft 100a to rotate, the slide plate 302a will not drive the lower support plate 201a to shake, improving the overall rigidity of the entire bending mechanism, thereby ensuring the bending accuracy when the metal plate or profile 200 is bent.

[0077] Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and its equivalent technologies, the present invention also intends to include these changes and modifications.
