Description

Technical Field

[0001] The utility model relates to the technical field of shell sheet metal processing, and particularly relates to a punching auxiliary tool for shell sheet metal processing. Background Art

[0002] Sheet metal processing is a key technology that sheet metal technicians need to master and is also an important process for the forming of sheet metal products. Sheet metal processing includes traditional methods such as cutting and blanking, punching, and bending and pressing forming, as well as process parameters. Sheet metal processing is used to make boxes, shells, iron barrels, ventilation ducts, etc. using sheets.

[0003] In the prior art, when manually positioning the punching of shell sheet metal, the common operation is to measure the hole spacing of the material to be punched with a tape measure, mark the hole positions with a pen, and then place the material on the punching machine for punching. This tape measure distance measurement method is cumbersome to operate, and the position of the material needs to be accurately corrected on the punching machine multiple times for each punching, seriously affecting the punching speed.

[0004] In response to the above problems, a prior patent (Publication No.: CN210754635U), a punching auxiliary tool for shell sheet metal processing, is provided. It is arranged on a base through a sliding guide rail, and support platforms are arranged on both sides of the sliding guide rail. The punching spacing positioning mechanism includes a punch positioning plate and a steel material positioning mechanism. The punch positioning plate is detachably connected to the support platform on one side of the sliding guide rail through a fastening bolt. A U-shaped through hole for positioning the punch position is arranged on the part of the punch positioning plate that exceeds the support platform. A plurality of equally spaced adjustment holes are arranged on the support platform. The spacing between the fastening bolts on the punch positioning plate matches the spacing of the adjustment holes. The material positioning mechanism includes a positioning pin and a fixed seat. The two ends of the fixed seat are movably arranged on the support platforms on both sides of the sliding guide rail. The positioning pin is rotatably connected to the fixed seat through a bolt. Compared with the traditional square tube punching process, the punching machine hole auxiliary device does not require scribing before punching, greatly reducing the labor intensity of workers and improving the punching efficiency.

[0005] In response to the above problems, the prior patent provides a solution. However, during the punching operation, the human hand is relatively close to the punching end, which is prone to large safety hazards, and the problem of perforation inclination may occur due to ineffective clamping of the sheet material.

[0006] Therefore, a punching auxiliary tool for shell sheet metal processing is proposed. Utility Model Content

[0007] The purpose of the present utility model is to provide a punching auxiliary tool for shell sheet metal processing, which can solve the problems that in the prior art, the human hand is relatively close to the punching end, prone to large safety hazards, and the problem of perforation inclination may occur due to ineffective clamping of the sheet material.

[0008] To achieve the above object, the present utility model provides the following technical solutions: A punching auxiliary tool for shell sheet metal processing, including a workbench, the bottom of the workbench is fixedly connected with a base, the top of the workbench is movably connected with a linkage mechanism, the outside of the linkage mechanism is movably connected with a clamping mechanism, the rear side of the workbench is movably connected with an electronic telescopic column, the top of the electronic telescopic column is fixedly connected with a punching module, the bottom of the punching module is fixedly connected with a telescopic rod, and the bottom of the telescopic rod is fixedly connected with an elastic pressure plate;

[0009] The linkage mechanism includes a chute, a slider, a movable plate, a pull rod and a connecting rod. The chute is opened on the top of the workbench, the movable plate is movably connected to the top of the workbench, the slider is fixedly connected to the bottom of the movable plate, the slider is slidably connected to the inside of the chute, the pull rod is fixedly connected to the right side of the movable plate, and the connecting rod is fixedly connected to the right side of the pull rod.

[0010] Preferably, clamping support plates are fixedly connected to both the left and right sides of the movable plate. A sliding rod is slidably connected to the inside of the clamping support plate. Clamping blocks are fixedly connected to the left side of the right sliding rod and the right side of the left sliding rod, and the clamping blocks are arranged on the top of the movable plate.

[0011] Preferably, a clamping groove is opened on the inside of the sliding rod, a clamping block is opened on the inside of the clamping groove, and the clamping block is movably connected to the inside of the clamping support plate.

[0012] Preferably, a pulling block is fixedly connected to the top of the clamping block, and tension springs are fixedly connected to both the bottom of the pulling block and the top of the clamping support plate.

[0013] Preferably, discharge ports are opened on the inside of both the workbench and the movable plate.

[0014] Preferably, a material guiding groove is opened on the inside of the base, and the material guiding groove is arranged at the bottom of the discharge port.

[0015] Preferably, a resilient support rod is fixedly connected to the top of the clamping support plate, and a limiting groove is opened on the bottom of the pulling block.

[0016] Preferably, an anti-slip pad is fixedly connected to the inside of the clamping block.

[0017] Compared with the prior art, the beneficial effects of the present utility model are:

[0018] 1. By providing a chute on the workbench, a movable composite workbench, i.e., a movable plate, can be placed on the workbench. The material to be perforated is placed on the movable plate. By pulling the connecting rod to drive the movable plate to move left and right for perforation operations, it is possible to avoid the need for personnel to constantly be beside the perforation module. The position of the material can be adjusted by operating the movable plate, and then perforation can be carried out. In this way, to a certain extent, it can avoid the safety hazards that are prone to occur during multiple perforations in traditional perforation operations, where personnel need to be beside the perforation to adjust the position of the material.

[0019] 2. By providing clamping blocks, the material on the movable plate can be tightly clamped. By pulling the pulling block to disengage the clamping block from the card slot, and then inserting the resilient support rod into the limiting slot to support the pulling block, it is possible to pull the clamping block inward to make it fit the material. Then, the resilient support rod is lowered, and the clamping block is snapped back into the card slot by the pulling force of the tension spring for locking and limiting. In this way, the material on the movable plate can be limited left and right. Since the movable plate moves left and right, it will exert forces to the left and right, thus achieving effective clamping. Secondly, by providing an elastic pressure plate beside the perforation module, when the electronic telescopic column drives the perforation module to descend, it can be pressed tightly by the elastic pressure plate, further clamping the plate. In this way, manual pressing can be avoided, and the material can move with the movable plate without skewing, preventing perforation errors during the perforation operation.

Detailed implementation manners

[0027] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0028] Please refer to Figures 1-6 , the present invention provides a technical solution:

[0029] A punching auxiliary tool for shell sheet metal processing includes a workbench 1. A base 2 is fixedly connected to the bottom of the workbench 1. A linkage mechanism 3 is movably connected to the top of the workbench 1. A clamping mechanism 4 is movably connected to the outside of the linkage mechanism 3. An electronic telescopic column 13 is movably connected to the rear side of the workbench 1. A punching module 5 is fixedly connected to the top of the electronic telescopic column 13. A telescopic rod 6 is fixedly connected to the bottom of the punching module 5. An elastic pressure plate 7 is fixedly connected to the bottom of the telescopic rod 6;

[0030] The linkage mechanism 3 includes a chute 31, a slider 32, a movable plate 33, a pull rod 34 and a connecting rod 35. The chute 31 is opened on the top of the workbench 1. The movable plate 33 is movably connected to the top of the workbench 1. The slider 32 is fixedly connected to the bottom of the movable plate 33. The slider 32 is slidably connected to the inside of the chute 31. The pull rod 34 is fixedly connected to the right side of the movable plate 33. The connecting rod 35 is fixedly connected to the right side of the pull rod 34.

[0031] In this embodiment: By opening the chute 31 on the workbench 1, a movable composite workbench 1, that is, the movable plate 33, can be arranged on the workbench 1. The material to be perforated is fixed on the movable plate 33. By pulling the connecting rod 35 to drive the pull rod 34 to drive the slider 32 at the bottom of the movable plate 33 to move left and right in the chute 31, the punching operation can be carried out. It can make the human hand not need to be beside the punching module all the time. The position of the material can be adjusted by operating the movable plate 33, and then the punching can be carried out.

[0032] Specifically, as Figure 1 ,Figure 2 , Figure 4 As shown in Figure 4 , clamping support plates 41 are fixedly connected to both the left and right sides of the movable plate 33. A sliding rod 42 is slidably connected to the inner side of the clamping support plate 41. Clamping blocks 43 are fixedly connected to both the left side of the right sliding rod 42 and the right side of the left sliding rod 42. The clamping blocks 43 are arranged on the top of the movable plate 33.

[0033] Specifically, as Figure 1 , Figure 2 , Figure 4 shown in Figure 1 , Figure 2 , and Figure 4 , a card slot 44 is formed inside the sliding rod 42, and a clamping block 45 is formed inside the card slot 44. The clamping block 45 is movably connected to the inner side of the clamping support plate 41.

[0034] Specifically, as Figure 1 , Figure 2 , Figure 4 , Figure 6 shown in Figure 1 , Figure 2 , Figure 4 , Figure 6 , a pulling block 47 is fixedly connected to the top of the clamping block 45. Tensile springs 46 are fixedly connected to both the bottom of the pulling block 47 and the top of the clamping support plate 41.

[0035] In this embodiment: By pulling the pulling block 47 to make the clamping block 45 disengage from the card slot 44, then pulling the clamping block 43 inward to make it fit against the material, and then releasing the pulling block 47, the clamping block 45 springs back into the card slot 44 under the pulling force of the tensile spring 46 for clamping and limiting. In this way, the material on the movable plate 33 can be limited in the left and right directions. Since the movable plate 33 will exert leftward and rightward forces when moving left and right, effective clamping can be achieved.

[0036] Specifically, as Figure 1 , Figure 2 , Figure 5 shown in Figure 1 , Figure 2 , and Figure 5 , discharge ports 8 are formed inside both the workbench 1 and the movable plate 33.

[0037] Specifically, as Figure 1 , Figure 2 , Figure 5 shown in Figure 1 , Figure 2 , and Figure 5 , a material guiding groove 9 is formed inside the base 2. The material guiding groove 9 is arranged at the bottom of the discharge port 8.

[0038] In this embodiment: By providing the discharge ports 8 on the movable plate 33 and the workbench 1, on the one hand, during the perforation operation, the perforation module will not directly contact the movable plate 33 and the workbench 1, avoiding damage. On the other hand, the perforated wafers can be discharged into the material guiding groove 9 in a timely manner for discharge treatment to avoid affecting subsequent perforation operations.

[0039] Specifically, as Figure 2 , Figure 6 shown in Figure 2 and Figure 6 , a resilient support rod 10 is fixedly connected to the top of the clamping support plate 41, and a limiting groove 11 is formed at the bottom of the pulling block 47.

[0040] Specifically, as Figure 1 , Figure 2 , Figure 4 shown, an anti-slip pad 12 is fixedly connected to the inner side of the clamping block 43.

[0041] In this embodiment: By providing the resilient support rod 10, the lifted pull block 47 can be supported and limited, so that the position of the clamping block 43 can be adjusted without human hands. Secondly, the anti-slip pad 12 is provided so that the clamping block 43 can better clamp the material and prevent it from slipping sideways during movement.

[0042] Working principle: Before performing the perforation operation, by pulling the pull block 47, the clamping block 45 is disengaged from the card slot 44, and then the resilient support rod 10 is inserted into the limit slot 11 to support the pull block 47, so that the clamping block 43 can be pulled inwards to fit the material. Then the resilient support rod 10 is lowered, so that the clamping block 45 springs back into the card slot 44 under the tension of the tension spring 46 for clamping and limiting. In this way, the material on the movable plate 33 can be limited left and right. Because the movable plate 33 gives left and right forces when moving left and right, effective clamping can be achieved. By pulling the connecting rod 35 to drive the pull rod 34 to drive the slider 32 at the bottom of the movable plate 33 to move left and right in the chute 31, the perforation operation can be performed, so that the human hand does not need to be always beside the perforation module. The position of the material can be adjusted by operating the movable plate 33, and then the electronic telescopic column 13 drives the perforation module to descend, so that the perforation operation is performed. When the electronic telescopic column 13 descends, the elastic pressure plate 7 will descend accordingly to press the material on the movable plate 33. As the movable plate 33 is manually pulled, perforation is pressed when the electronic telescopic column 13 descends, and the position is adjusted manually when it rises. And during the perforation operation, by providing a discharge port 8 on the movable plate 33 and the workbench 1, on the one hand, during the perforation operation, the perforation module will not directly contact the movable plate 33 and the workbench 1 to avoid damage. On the other hand, the perforated discs can be discharged into the guide groove 9 in time to avoid affecting the subsequent perforation operation.

[0043] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
