Description

Technical Field

[0001] The invention relates to the technical field of slotting machines, in particular to a gantry type metal sheet slotting machine. Background Art

[0002] Grooving is an auxiliary process for bending metal or non-metal materials. A V-shaped groove is cut out at the bending line of the metal or non-metal material using a special equipment tool, so that the material is easy to bend and the outer R of the bending angle can be minimized. Then the material is bent by a bending machine or manually. In this way, the processing is completed and the product appearance requirements are met. The depth, width and angle of the V-groove can be guaranteed by the feed amount and shape of the planer during planing. Grooving tools are used to groove materials.

[0003] The patent publication number CN220515535U discloses a side clamping structure of a gantry type metal sheet grooving machine. The drive assembly is set to facilitate the grooving cutter to process the metal sheet and clamp the metal sheet at the same time, thereby improving convenience. It is worth mentioning that when the grooving cutter processes the metal sheet, the pressure from the transmission rod on the clamping plate parallel to it is the greatest, which can further enhance the clamping effect. By providing a slide plate and a slider, the transmission plate can follow the longitudinal drive mechanism to move and perform the clamping work under the action of the longitudinal drive mechanism.

[0004] The existing patents have the following defects:

[0005] In the process of grooving a stainless steel workpiece, the existing device needs to fix the stainless steel workpiece first, and then use a V-shaped grooving cutter head to grooving the position where the stainless steel workpiece needs to be grooved. Grooving is to enable the workpiece to be bent better. The bending angle is determined by the sharpness of the grooving machine head. The sharper the grooving head, the sharper the V-groove, the larger the bending angle, and the higher the adaptability. However, the current grooving equipment can only use grooving cutter heads of the same specification, resulting in only grooving of the same taper. It cannot adapt to the requirements of different bending angles during the processing of metal sheets, which limits the flexibility of processing and production; and when replacing grooving cutter heads of different specifications, it is necessary to use tools such as wrenches or screwdrivers to disassemble the old cutter heads and then install the new cutter heads. Manually replacing the cutter heads requires a lot of time for assembly, disassembly, installation and debugging. The operation is cumbersome, and the installation and disassembly efficiency is low, which reduces the working efficiency of the machine tool. Summary of the invention

[0006] In view of the problem that the prior art slotting machine can only use a single cutter head for slotting during the slotting process and the cutter head is troublesome to replace, a gantry type metal sheet slotting machine is proposed.

[0020] Beneficial effects of the present invention:

[0021] 1. By rotating the push plate, the notch allows the clamping assembly to slide on the turntable.

[0022] 2. By pushing the component, the turntable and the connecting shaft are driven to rotate, and the groove cutter head is driven to rotate, so that the groove cutter head can be switched. When the turntable rotates, the clamping rod slides on the side of the turntable. When sliding to the clamping groove position, the clamping rod is re-clamped with the clamping groove under the action of the first spring reset, and the turntable is limited. When switching the groove cutter head, the turntable can rotate, which is convenient for switching the groove cutter head. After the groove cutter head is switched, the turntable is clamped and limited, making the groove cutter head more stable after switching.

[0023] 3. By rotating the push rod, under the action of the conical block, the insertion rod is disengaged from the inner side of the card slot, and the second spring is compressed to make the conical block slide on the side of the turntable. When the conical block slides to the card slot, under the action of the second spring, the insertion rod and the conical block are driven to move, so that the conical block moves into the card slot. At this time, the push rod is rotated to drive the insertion rod and the conical block to rotate, and the turntable and the connecting shaft are driven to rotate, so as to switch the grooving cutter head, thereby avoiding the situation that only one specification of cutter head can be used when grooving the metal sheet, resulting in only being able to groove the same taper slot, which cannot meet the requirements of different bending angles during the processing of the metal sheet.

DETAILED DESCRIPTION

[0037] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0038] Example 1, reference Figure 1-Figure 6 , which is the first embodiment of the present invention, provides a gantry type metal sheet slotting machine, including a slotting bed 1, a moving frame 13 movably mounted on the top of the slotting bed 1, a moving seat 14 movably mounted on the moving frame 13, a cutter head mounting seat 11 movably mounted at the bottom of the moving seat 14, and a plurality of slotting cutter heads 12 rotatably mounted in the cutter head mounting seat 11 and distributed in a linear array, and also includes a switching control unit and a cutter head mounting assembly 9 mounted on the cutter head mounting seat 11; the switching control unit includes a rotating component mounted on the cutter head mounting seat 11, and a pushing component mounted on one side of the rotating component, the rotating component includes a transmission assembly 2 mounted on the cutter head mounting seat 11, and a clamping assembly 3 mounted on one side of the transmission assembly 2; the transmission assembly 2 includes a movable groove 23 opened on the cutter head mounting seat 11, a connecting shaft 25 is rotatably connected in the movable groove 23, a pushing disk 21 is rotatably connected on the shaft wall of the connecting shaft 25, a rotating disk 22 is fixedly connected on the shaft wall of the connecting shaft 25 at the top of the pushing disk 21, and a notch 24 is opened on one side of the pushing disk 21.

[0039] Specifically, when in use, a metal sheet is placed on the groover bed 1, and the metal sheet is clamped by a plurality of clamping plates installed at one edge of the groover bed 1. The movable frame 13 moves on the groover bed 1, driving the movable seat 14 and the cutter head mounting seat 11 to move, thereby driving the groover head 12 to move on the metal sheet to groove the metal sheet, and the movable seat 14 slides on the movable frame 13, driving the cutter head mounting seat 11 to move, thereby driving the groover head 12 to move left and right, and the position of the groover head 12 can be adjusted to groove different positions of the metal sheet. By driving the rotating component to rotate through the pushing component, the groove cutter head 12 is driven to rotate in the cutter head mounting seat 11, and the groove cutter heads 12 with different sharpness can be switched for groove cutting. By rotating the pushing disk 21, the clamping component 3 slides on the turntable 22 under the action of the notch 24. When the pushing disk 21 rotates, the turntable 22 is driven to rotate, and then the connecting shaft 25 is driven to rotate, and the groove cutter head 12 is driven to rotate on the cutter head mounting seat 11. When the clamping component 3 is clamped with the turntable 22, the turntable 22 is limited, and then the connecting shaft 25 is limited, so that the groove cutter head 12 is switched. Not only the groove cutter head 12 is switched, but also the switching process is fast and efficient, which increases the flexibility of processing and production and improves the working efficiency of the machine tool.

[0040] Reference Figure 4-Figure 6 The clamping assembly 3 includes a first movable cavity 34 opened on the cutter head mounting seat 11, a first spring 33 is fixedly connected to the bottom wall of the first movable cavity 34, a clamping rod 32 is fixedly connected to one end of the first spring 33 close to the outer side of the first movable cavity 34, a moving rod 31 is fixedly connected to the rod wall of the clamping rod 32, the moving rod 31 is slidably connected to the notch 24, a clamping groove 35 is opened in an annular array on the turntable 22, and the end of the clamping rod 32 away from the first spring 33 is limitedly clamped in the clamping groove 35.

[0041] Specifically, before the pushing plate 21 is pushed, the engaging rod 32 is in an engaging state with the engaging groove 35, and the rotating plate 22 is limited and locked. The moving rod 31 is located on the inner side of the notch 24. When the pushing plate 21 rotates, the moving rod 31 slides in the notch 24. Under the action of the notch 24, the moving rod 31 is pushed, so that the moving rod 31 moves to the outside of the notch 24, is located on the side of the pushing plate 21, and slides on the side of the pushing plate 21, driving the engaging rod 32 to retract into the first movable cavity 34, and compressing the first spring 33, so that the engaging rod 32 disengages from the engaging groove 35, and the limiting of the rotating plate 22 is released. Under the action of the pushing component, the turntable 22 and the connecting shaft 25 are driven to rotate, and the groove cutter head 12 is driven to rotate, so that the groove cutter head 12 can be switched. When the turntable 22 rotates, the clamping rod 32 slides on the side of the turntable 22. When sliding to the position of the clamping groove 35, the clamping rod 32 is re-clamped with the clamping groove 35 under the reset action of the first spring 33, and the turntable 22 is limited. When switching the groove cutter head 12, the turntable 22 can rotate, which is convenient for switching the groove cutter head 12. After the groove cutter head 12 is switched, the turntable 22 is clamped and limited, so that the groove cutter head 12 is more stable after switching.

[0042] Reference Figure 3-Figure 8 The pushing component includes a pushing component 4 fixedly installed on one side of the pushing disk 21, and a guide component 5 installed in the pushing component 4; the pushing component 4 includes an L-shaped plate 41 fixedly connected to the pushing disk 21, a pushing rod 42 fixedly connected to the L-shaped plate 41, an insertion rod 44 slidably connected between the L-shaped plate 41 and the pushing rod 42, an insertion rod 44 is fixedly connected to one end away from the pushing rod 42 with a conical block 45, the conical block 45 is plugged into the clamping groove 35, a second active cavity 46 is opened on the pushing rod 42, an end of the insertion rod 44 away from the conical block 45 extends to the inner side of the second active cavity 46 and is fixedly connected with a second spring 47, an end of the second spring 47 away from the insertion rod 44 is fixedly connected to the bottom wall of the second active cavity 46, and a protective sleeve 43 is fixedly sleeved on the rod wall of the pushing rod 42.

[0043] Specifically, before switching the slotting cutter head 12, under the action of the second spring 47, the insertion rod 44 moves toward the outside of the second active cavity 46, so that the conical block 45 is engaged in one of the engaging grooves 35. When switching the slotting cutter head 12, the adjustment personnel holds the push rod 42 by hand and pulls the push rod 42 clockwise or counterclockwise, so that the inclined surface of the conical block 45 squeezes the groove edge of the engaging groove 35, so that the insertion rod 44 shrinks into the push rod 42 and gradually disengages from the engaging groove 35, compressing the second spring 47 so that the conical block 45 slides on the side of the turntable 22. When the conical block 45 slides to the engaging groove 35, , under the action of the second spring 47, the insertion rod 44 and the tapered block 45 are driven to move, so that the tapered block 45 moves into the clamping groove 35. At this time, the push rod 42 is rotated to drive the insertion rod 44 and the tapered block 45 to rotate, and the turntable 22 and the connecting shaft 25 are driven to rotate, and the grooving cutter head 12 is switched. The protective sleeve 43 is used to protect the hands of the adjuster to avoid wear between the hands of the adjuster and the push rod 42, avoiding the use of only one specification of cutter head when grooving the metal sheet, resulting in only being able to groove the same taper of the groove, which cannot meet the requirements of different bending angles during the processing of the metal sheet.

[0044] Reference Figure 7 and Figure 8 The guide assembly 5 includes two guide grooves 51 symmetrically distributed and opened in the second active cavity 46 , and guide blocks 52 are slidably connected in the two guide grooves 51 , and the two guide blocks 52 are fixedly connected to the insertion rod 44 .

[0045] Specifically, when the insertion rod 44 moves in the second movable cavity 46, the guide block 52 slides in the guide groove 51, so that the insertion rod 44 can only move in the horizontal direction, limiting the rotation of the insertion rod 44 in the vertical direction, making it easier to lock the insertion rod 44, and preventing the insertion rod 44 from moving in the second movable cavity 46 all the time, making it impossible for the grooving cutter head 12 to be switched.

[0046] Example 2, reference Fig. 9 and Fig.10, which is the second embodiment of the present invention. This embodiment is different from the first embodiment in that: the switching control unit also includes a locking component installed on the pushing component, the locking component includes a pressing component 6 installed on the pushing rod 42, a limiting component 7 installed in the middle of the pressing component 6, and a locking component 8 installed at the bottom of the pressing component 6; the pressing component 6 includes a sliding box body 61 fixedly connected to the pushing rod 42, a sliding block 62 is slidably connected in the sliding box body 61, a pressing rod 63 is slidably connected to the top of the sliding box body 61, the bottom of the pressing rod 63 is fixedly connected to the sliding block 62, the bottom of the sliding block 62 is fixedly connected to two symmetrically distributed return springs 66, the bottom of the sliding box body 61 is rotatably connected to the limiting rod 65, the top of the limiting rod 65 is fixedly connected to the sliding rod 64, and the sliding rod 64 is slidably connected to the sliding block 62.

[0047] Specifically, when locking the plug rod 44, pressing the pressing rod 63 drives the sliding block 62 to slide downward in the sliding box body 61, compressing the return spring 66, so that the limiting rod 65 rotates on the sliding box body 61, so that the sliding rod 64 slides on the sliding block 62, and under the action of the limiting assembly 7, the sliding rod 64 is limited so that the sliding block 62 stays in the middle of the sliding box body 61, thereby allowing the locking assembly 8 to lock the plug rod 44. When the lock of the plug rod 44 is released, the pressing rod 63 is pressed again, so that the limiting rod 65 is deflected on the sliding box body 61, so that the sliding rod 6 The sliding block 62 slides, and under the action of the limit assembly 7, the sliding rod 64 slides to the bottom of the sliding block 62. Under the reset action of the reset spring 66, the sliding block 62 slides toward the top of the sliding box body 61, and finally stops at the top of the sliding box body 61, so that the locking assembly 8 unlocks the insertion rod 44. Before switching the grooving cutter head 12, the pressing rod 63 is pressed to unlock the insertion rod 44. When switching the grooving cutter head 12, the pressing rod 63 is pressed again to lock the insertion rod 44, which facilitates the arbitrary switching of the grooving cutter head 12, is simple to operate, and improves the working efficiency of the machine tool.

[0048] Reference Fig. 9 and Fig.10 The limiting assembly 7 includes a reciprocating groove 71 provided on the sliding block 62, the sliding rod 64 is slidably connected in the reciprocating groove 71, a bottom arc portion 72 is provided at the bottom of the reciprocating groove 71, a lower oblique stop portion 73 is provided at the top of the bottom arc portion 72 of the reciprocating groove 71, an upper V-shaped portion 75 is provided at the top of the reciprocating groove 71, and an upper oblique stop portion 74 is provided at the upper end of the upper V-shaped portion 75 of the reciprocating groove 71.

[0049] When the locking cam 74 is in the unlocked state, the locking cam 63 is pressed again to lock the locking cam 64 in the unlocked state.

[0050] Reference Figure 8 and Fig. 9 The locking assembly 8 includes a locking rod 81 fixedly connected to the bottom of the sliding block 62, a locking groove 82 is opened on the rod wall of the insertion rod 44, and the locking rod 81 passes through the sliding box body 61 and is limitedly engaged with the locking groove 82.

[0051] Specifically, the sliding block 62 slides downward in the sliding box body 61, driving the locking rod 81 to slide downward, so that the locking rod 81 is engaged with the locking groove 82, locking the insertion rod 44, and preventing the insertion rod 44 from sliding freely in the second active cavity 46, affecting the switching of the planing cutter head 12. The sliding block 62 slides upward in the sliding box body 61, driving the locking rod 81 to slide upward, so that the locking rod 81 is disengaged from the locking groove 82, and the locking of the insertion rod 44 is released, so that the planing cutter head 12 can be conveniently switched. The rest of the structure is the same as that of the first embodiment.

[0052] Example 3, reference Figure 2-Figure 4 , which is the third embodiment of the present invention. This embodiment is different from the second embodiment in that: the cutter head mounting assembly 9 includes a fixed shaft 92 rotatably connected to the cutter head mounting seat 11, one end of the fixed shaft 92 is fixedly connected to the connecting shaft 25, a plurality of evenly distributed fixed disks 91 are fixedly connected to the shaft wall of the fixed shaft 92, and the grooving cutter head 12 is fixedly connected to the fixed disk 91.

[0053] Specifically, the grooving cutter heads 12 are distributed in a circular array on the fixed disk 91. When the connecting shaft 25 rotates, it drives the fixed shaft 92 to rotate, drives the fixed disk 91 to rotate, and then drives the grooving cutter heads 12 to rotate, so that grooving cutter heads 12 of different specifications can be switched. Compared with the traditional grooving cutter heads 12 fixedly mounted on the cutter head mounting seat 11 by bolts, this method of grooving cutter heads 12 is easier to switch. During the grooving process, cutter heads of different specifications can be switched arbitrarily for grooving, and the grooving efficiency is higher. The rest of the structure is the same as that of Example 2.

[0054] In summary, the working principle of the present invention is as follows: when in use, the adjuster holds the push rod 42 with his hand and presses the pressing rod 63. Under the action of the upper oblique stopper 74, the limit rod 65 is deflected to the right on the sliding box body 61. Under the action of the reset spring 66, the sliding rod 64 slides downward in the reciprocating groove 71 and stays in the bottom arc-shaped portion 72, so that the sliding block 62 stays at the top of the sliding box body 61, driving the locking rod 81 to slide upward, so that the locking rod 81 is disengaged from the locking groove 82, and the locking of the insertion rod 44 is released, and the clockwise rotation Or, the push rod 42 is rotated counterclockwise, and under the action of the inclined surface of the conical block 45, the insertion rod 44 is disengaged from the clamping groove 35, and the second spring 47 is compressed, so that the conical block 45 slides on the side of the rotating disk 22, and under the action of the notch 24, the moving rod 31 is pushed, so that the moving rod 31 moves to the outside of the notch 24, is located on the side of the pushing disk 21, and slides on the side of the pushing disk 21, driving the clamping rod 32 to move into the first movable cavity 34, compressing the first spring 33, so that the clamping rod 32 is disengaged from the clamping groove 35, and the limit of the rotating disk 22 is released. Under the action of the spring 47 returning to its original position, the insertion rod 44 drives the tapered block 45 to be inserted into one of the engaging grooves 35, and the pressing rod 63 is pressed again. Under the action of the lower oblique stop 73, the limiting rod 65 is deflected to the left on the sliding box body 61, so that the sliding rod 64 slides upward in the reciprocating groove 71 and enters the upper V-shaped portion 75, so that the sliding block 62 slides downward in the sliding box body 61, driving the locking rod 81 to slide downward, so that the locking rod 81 is engaged with the locking groove 82, and the insertion rod 44 is locked. At this time, the tapered block 45 will be inserted into the engaging groove 35 and cannot be locked. When the rotating disk 22 rotates, the clamping rod 32 slides on the side of the rotating disk 22. When the clamping groove 35 moves to the clamping rod 32, the first spring 33 resets the clamping rod 32 and the inner side of the clamping groove 35 to limit the position of the rotating disk 22, and the rotating disk 22 is limited to complete the switching of the clamping head 12. The operation is simple and convenient, which improves the working efficiency of the machine tool and increases the flexibility of processing and production.

[0055] It should be noted that the above embodiments are only used to illustrate the technical solution of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solution of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solution of the present invention.
