Description

Technical Field

[0001] The present application relates to the field of sheet metal punching technology, and in particular to a punching device. Background Art

[0002] Rectangular plates are a common geometric shape that is used in many fields. For example, in building materials, rectangular plates can be used for decoration and support of ceilings, walls or other structures. Depending on the requirements, some rectangular plates are provided with through holes running through the length direction.

[0003] In the related art, the through-hole operation of a rectangular plate usually adopts a secondary single-hole punching method, in which the plate is fixed on a workbench and drilled with a drill bit. After the drilling is completed, the plate is rotated 180° and the second hole is punched, and the punching operation is completed by two punching operations.

[0004] The prior art has the following problems: when the above-mentioned punching method is used, the operator needs to wait for the sheet to rotate before punching a second time, which takes a lot of time and has low work efficiency, and there is still room for improvement. Utility Model Content

[0005] In order to improve the situation where a secondary single-hole punching method is used when some plates need to be provided with through holes penetrating along the length direction, and the operator needs to wait for the secondary punching, which consumes a lot of time and has low work efficiency, the present application provides a punching device.

[0006] The punching device provided in this application adopts the following technical solution:

[0007] A punching device, comprising:

[0008] Base;

[0009] A workbench, fixedly connected to the base, wherein the workbench is provided with a placement station for placing the sheet material; and

[0010] A punching assembly is fixedly connected to the base and disposed on two opposite sides of the workbench, and the punching assembly includes:

[0011] A drill bit is slidably connected to the base, and the drill bits on the two sets of punching assemblies are arranged on the same axis; and

[0012] A driving member is fixedly connected to the base, and the driving member is electrically connected to the drill bit to control the rotation of the drill bit.

[0013] By adopting the above technical solution, when the device is started, the drill bits on both sides work in sequence. When the drill bit on one side works, the drill bit on the other side works at the same time. After the drill bit on one side completes drilling, the drill bit on the other side penetrates the remaining part between the two holes, avoiding interference between the two drill bits, greatly reducing the time of the drilling operation, improving the work efficiency of the drilling operation, and enhancing the efficiency of the device.

[0014] Optionally, the punching assembly further includes a coaxial adjustment member for controlling the movement of the drill bit, and the coaxial adjustment member includes:

[0015] A first adjusting block, fixedly connected to the base;

[0016] A second adjusting block is slidably connected to a side of the first adjusting block away from the base, and the second adjusting block slides along the width direction of the sheet material on the placement station;

[0017] a third adjusting block, slidably connected to one side of the second adjusting block in a vertical direction; and

[0018] The connecting block is slidably connected to one side of the third adjusting block along the length direction of the sheet material on the placing station, and the drill bit is fixedly connected to one side of the connecting block close to the workbench.

[0019] By adopting the above technical solution, before the operator performs the operation, the coaxial adjustment part is controlled to set the drill bits on both sides on the same axis, thereby improving the coaxiality between the two drill bits and reducing the concentricity of the opened hole, thereby improving the accuracy of the opened hole, enhancing product quality, and improving the qualified rate.

[0020] Optionally, a first cylinder is fixedly connected to the workbench, a clamping block is provided on the workbench, the clamping block is fixedly connected to a piston rod of the first cylinder, and the piston rod of the first cylinder moves in a vertical direction.

[0021] By adopting the above technical solution, when the sheet is placed on the workbench, the first cylinder pushes the clamping block to fix the sheet, reducing the probability of the sheet being displaced by the impact force of the drill bit, improving the stability of the device, and improving the product qualification rate.

[0022] Optionally, a plurality of limit columns are fixedly connected to the workbench, and abutment surfaces for the sheet materials on the placement station to abut are provided on the plurality of limit columns.

[0023] By adopting the above technical solution, when the operator places the sheet, the limit column positions the sheet, reducing the probability of the through hole position being offset due to incorrect sheet placement, further limiting the movement of the sheet, and at the same time reducing the damage to the drill bit caused by irregular placement of the sheet, thereby reducing the failure rate of the device.

[0024] Optionally, a second cylinder is fixedly connected to the workbench, and a clamping block is slidably connected to the workbench to press the sheet on the placement station against the abutment surface. The clamping block is fixedly connected to the piston rod of the second cylinder, and the piston rod of the second cylinder moves toward or away from the placement station.

[0025] By adopting the above technical solution, when the second cylinder pushes the clamping block, the clamping block presses the sheet material against the clamping surface, and cooperates with the limiting column to further fix the sheet material, thereby reducing the difficulty of placement and positioning for the operator, improving the operator's work efficiency, and enhancing stability during punching operations.

[0026] Optionally, a limiting groove is provided on the workbench, and the second cylinder and the abutting block are integrally embedded in the limiting groove, and a side of the abutting block close to the limiting column abuts against a side wall of the limiting groove.

[0027] By adopting the above technical solution, when the second cylinder pushes the clamping block, the limit groove limits the movement of the clamping block, reducing the risk of excessive pushing of the second cylinder, causing the sheet material to be compressed and causing damage to the limit column, reducing the failure rate of the device, and increasing the service life of the limit column.

[0028] Optionally, the first adjusting block, the second adjusting block and the third adjusting block are provided with straight sliding modules for respectively allowing the second adjusting block, the third adjusting block and the connecting block to slide.

[0029] By adopting the above technical solution, when the operator adjusts the coaxial adjustment part, the one-way sliding module reduces the difficulty of the operator's debugging and improves the operator's work efficiency. At the same time, it is convenient for the operator to maintain and replace, and improves stability.

[0030] Optionally, a support column is fixedly connected to the side of the workbench away from the base, and the number of the support columns is two. A connecting plate is provided on the side of the two support columns away from the base, and the first cylinder is fixedly connected to the side of the connecting plate away from the workbench, and the piston rod of the first cylinder is passed through the connecting plate.

[0031] By adopting the above technical solution, when a support column is set on the workbench and the connecting plate is fixedly connected to the support column, a support frame is formed to provide an upward supporting force to the first cylinder, thereby improving the bearing capacity of the connecting plate, reducing the probability of the first cylinder falling due to the gravity of the clamping block, improving the stability of the first cylinder, and reducing the failure rate.

[0032] Optionally, a guide rod is fixedly connected to the connecting plate and is sequentially inserted into the connecting plate and the clamping block.

[0033] By adopting the above technical solution, when the first cylinder is started, the clamping block moves along the guide rod in the vertical direction and toward the side close to the placement station, reducing the situation where the clamping block is unevenly stressed during movement and is offset, thereby failing to complete the action of clamping the sheet material, thereby improving the stability of clamping and enhancing the precision and effectiveness of clamping.

[0034] Optionally, the base is provided with an inclined surface for guiding waste chips to slide down.

[0035] By adopting the above technical solution, when the device is running, waste chips formed by drill punching splash through the opening, and most of the waste chips slide down the inclined surface, which is convenient for the operator to perform subsequent cleaning operations, reduces the impact of waste chip accumulation on the clogging of device components, increases the service life of components, avoids frequent cleaning and maintenance by operators, and thus improves the work efficiency of operators.

[0036] In summary, the present application includes at least one of the following beneficial technical effects:

[0037] 1. The side drill bits work in sequence. When one side drill bit is working, the other side drill bit is working at the same time. After one side drill bit completes drilling, the other side drill bit will penetrate the remaining part between the two holes, thus avoiding interference between the two drill bits, greatly reducing the drilling operation time, improving the working efficiency of the drilling operation, and enhancing the efficiency of the device;

[0038] 2. The coaxial adjustment piece improves the coaxiality between the two drill bits, which reduces the concentricity of the opened hole, thereby improving the accuracy of the opened hole, enhancing product quality and improving the qualified rate;

[0039] 3. The limit column positions the sheet material, further restricting the movement of the sheet material, while reducing the damage to the drill bit caused by irregular placement of the sheet material and reducing the failure rate of the device. BRIEF DESCRIPTION OF THE DRAWINGS
