corner cutting device

Abstract

This utility model discloses a corner-cutting device, including a base with two opposing corner-cutting mechanisms on the base. Each corner-cutting mechanism includes a lower punch and an upper punch, each positioned vertically. The lower punch has a punching hole, and the upper punch has a punching block. The two upper punches can move synchronously up and down relative to their corresponding lower punches, causing the two punching blocks to simultaneously insert into or withdraw from their corresponding punching holes. After withdrawing from the punching hole, the punching block cooperates with the corresponding lower punch to form a material passage gap. The two corner-cutting mechanisms can move synchronously relative to the base, causing the two punching holes to move closer or further apart. Because the two material passage gaps are interconnected for material passage, and the synchronous up and down movement of the two upper punches causes the two punching blocks to simultaneously insert into or withdraw from their corresponding punching holes, the corner-cutting device can simultaneously punch corners on opposite sides of the material. Furthermore, because the two corner-cutting mechanisms can move synchronously relative to the base, causing the two punching holes to move closer or further apart, the size of the corner can be adjusted by adjusting the distance between the two punching holes, resulting in excellent adaptability.

Description

Technical Field

[0001] This utility model relates to the field of stamping equipment technology, and in particular to a corner cutting device. Background Technology

[0002] Stamping equipment is an industrial machine that uses powerful, controllable force to process metal or non-metal materials such as sheet metal, strip, and tube through a die, causing plastic deformation or separation to obtain parts (or stamped parts) with the required shape, size, and performance. Existing corner-cutting stamping equipment includes a lower punch and an upper punch. The lower punch has a stamping hole, and the upper punch has a stamping block. The upper punch can move up and down relative to the lower punch to insert or retract the stamping block into the stamping hole. When corners need to be stamped on opposite sides of a sheet metal, one corner must first be stamped on one side of the sheet, then the sheet is flipped over to stamp the other side. This operation is cumbersome and lacks automatic adjustment of the corner size, significantly limiting its application. Summary of the Invention

[0003] The purpose of this invention is to provide a corner-cutting device to solve the problem that existing corner-cutting stamping equipment cannot simultaneously stamp corners on opposite sides of a sheet.

[0004] This utility model is achieved through the following technical solution: A corner-cutting device includes a base on which two opposing corner-cutting mechanisms are provided. Each corner-cutting mechanism includes a lower punch and an upper punch arranged vertically. The upper punch is positioned higher, and the lower punch is positioned lower. The lower punch has a punching hole, and the upper punch has a punching block. The two upper punches can move synchronously up and down relative to their corresponding lower punches, causing the two punching blocks to synchronously insert into or withdraw from their corresponding punching holes. After withdrawing from the punching hole, the punching block cooperates with the corresponding lower punch to form a material passage gap. The two material passage gaps are interconnected. The two corner-cutting mechanisms can move synchronously relative to the base, causing the two punching holes to move closer to each other or further apart.

[0005] Furthermore, the direction of movement of the punching mechanism is defined as the front-to-back direction. The base is provided with a lead screw extending front-to-back and a motor that drives the lead screw to rotate. The two lower punches are respectively provided with sliding seats that are slidably connected to the lead screw. When the motor drives the lead screw to rotate, the two sliding seats move synchronously along the lead screw, so that the two punching mechanisms move closer to each other or farther apart.

[0006] Furthermore, the punching mechanism also includes a mounting component slidably connected to the base, the lower punch being fixed to the mounting component, the upper punch being slidably connected to the mounting component and located above the lower punch, and the mounting component having two material passage holes that are opposite to each other and communicate with the material passage gap.

[0007] Furthermore, the base is provided with two slide rails, which are opposite each other and extend back and forth. The mounting component is provided with a number of sliders that slide in cooperation with the two slide rails respectively.

[0008] Furthermore, the mounting component has a mounting cavity, and the lower punch and the upper punch are arranged vertically opposite each other in the mounting cavity, with the lower punch positioned lower and the upper punch positioned higher.

[0009] Furthermore, the lower punch is detachably and fixedly connected to the mounting component, and the stamping block is detachably and fixedly connected to the upper punch.

[0010] Furthermore, the mounting component is equipped with a cylinder that drives the upper punch to move up and down.

[0011] Furthermore, the punching hole is a through hole extending vertically, and the base is provided with a guide member below each of the two punching holes. The guide member is inclined from top to bottom in a direction away from the other punching mechanism.

[0012] Furthermore, the punching hole is a triangular hole, and the punching block is a triangular block that matches the shape of the punching hole, with the vertices of the two punching holes facing each other.

[0013] Furthermore, the base is provided with a displacement sensor next to the corner-attacking mechanism.

[0014] The advantages of this technical solution are that by configuring two corner-cutting mechanisms on the base, each corner-cutting mechanism includes a lower punch and an upper punch arranged vertically. The lower punch has a punching hole, and the upper punch has a punching block. The two upper punches can move up and down synchronously relative to the corresponding lower punches, allowing the two punching blocks to insert or withdraw from the corresponding punching holes synchronously. Therefore, the corner-cutting device can simultaneously punch corners on opposite sides of the material, making operation simple and quick. At the same time, by configuring the two corner-cutting mechanisms to move synchronously relative to the base, allowing the two punching holes to move closer or further apart, the corner-cutting device can adjust the size of the corner by adjusting the distance between the two punching holes, making operation simple and flexible, and with excellent adaptability.

Detailed Implementation

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Example: Figure 1-8 As shown, the corner-cutting device includes a base 1, on which two opposing corner-cutting mechanisms 2 are provided. Each corner-cutting mechanism 2 includes a lower punch 201 and an upper punch 202 arranged vertically. The upper punch 202 is positioned higher, and the lower punch 201 is positioned lower. The lower punch 201 is provided with a punching hole 203, and the upper punch 202 is provided with a punching block 204. The two upper punches 202 can move up and down synchronously relative to the corresponding lower punches 201, causing the two punching blocks 204 to simultaneously insert into or withdraw from the corresponding punching holes 203. After the punching block 204 withdraws from the punching hole 203, it cooperates with the corresponding lower punch 201 to form a material passage gap 205. The two material passage gaps 205 are interconnected to allow material to pass through. The two corner-cutting mechanisms 2 can move synchronously relative to the base 1, causing the two punching holes 203 to move closer to each other or further apart. Among them, the punching hole 203 is a triangular hole, and the punching block 204 is a triangular block that matches the shape of the punching hole 203. The vertices of the two punching holes 203 are opposite each other. The closer the two punching holes 203 are, the larger the cut angle punched on the material. The farther the two punching holes 203 are, the smaller the cut angle punched on the material.

[0020] When using this chamfering device to stamp sheet metal, the steps are as follows: First, the two upper punches 202 move upwards simultaneously, causing the two punch blocks 204 to exit the corresponding punch holes 203 simultaneously. The two punch blocks 204 cooperate with the corresponding lower punches 201 to form a material passage gap 205. The material passes through the punching mechanism 2 through the two material passage gaps 205, and the opposite sides of the material face the punch holes 203. Next, the two upper punches 202 move down synchronously, causing the two stamping blocks 204 to be inserted into the corresponding stamping holes 203 at the same time. When the stamping blocks 204 are inserted into the stamping holes 203, they punch out chamfers on the opposite sides of the material.

[0021] In summary, this embodiment provides a corner-cutting device to solve the problem that existing corner-cutting stamping equipment cannot simultaneously stamp corners on opposite sides of a sheet metal. This is mainly achieved by configuring two corner-cutting mechanisms 2 on the base 1. Each corner-cutting mechanism 2 includes a lower punch 201 and an upper punch 202 arranged vertically. The lower punch 201 has a stamping hole 203, and the upper punch 202 has a stamping block 204. The two upper punches 202 can move synchronously up and down relative to their corresponding lower punches 201, allowing the two stamping blocks 204 to simultaneously insert into or withdraw from their corresponding stamping holes 203. Therefore, this corner-cutting device can simultaneously stamp corners on opposite sides of the material, making operation simple and quick. Furthermore, by configuring the two corner-cutting mechanisms 2 to move synchronously relative to the base 1, allowing the two stamping holes 203 to move closer or further apart, the corner-cutting device can adjust the size of the corner by adjusting the distance between the two stamping holes 203. This makes operation simple, flexible, and adaptable.

[0022] In this embodiment of the invention, the moving direction of the punching mechanism 2 is defined as the front-to-back direction. The base 1 is provided with a lead screw 3 extending front-to-back and a motor 4 driving the lead screw 3 to rotate. Each of the two lower punches 201 is provided with a sliding seat 5 slidably connected to the lead screw 3. When the motor 4 drives the lead screw 3 to rotate, the two sliding seats 5 move synchronously along the lead screw 3, causing the two punching mechanisms 2 to move closer to each other or further apart. Specifically, when the two punching mechanisms 2 move closer to each other, the two punching holes 203 move closer to each other; when the two punching mechanisms 2 move further apart, the two punching holes 203 move further apart. This arrangement, by configuring the lead screw 3 and motor 4 on the base 1 and providing sliding seats 5 slidably connected to the lead screw 3 on each of the two lower punches 201, allows the two punching mechanisms 2 to move synchronously relative to the base 1, causing the two punching holes 203 to move closer to each other or further apart. The synchronous drive structure is simple and easy to implement.

[0023] In this embodiment of the invention, the punching mechanism 2 further includes a mounting member 206 slidably connected to the base 1. A lower punch 201 is fixedly mounted on the mounting member 206, and an upper punch 202 is slidably connected to the mounting member 206 and located above the lower punch 201. The mounting member 206 has two opposing material passage holes 207 that communicate with the material passage gap 205. This configuration, by slidably connecting the mounting member 206 to the base 1, fixing the lower punch 201 to the mounting member 206, and slidably connecting the upper punch 202 to the mounting member 206, ensures stable assembly and smooth movement of the punching mechanism 2 and the base 1.

[0024] In this embodiment of the invention, the base 1 is provided with two slide rails 6, which are opposite each other and extend forward and backward. The mounting component 206 is provided with a plurality of sliders 7 that are respectively slidably engaged with the two slide rails 6. By configuring two slide rails 6 that are opposite each other and extend forward and backward on the base 1, and configuring a plurality of sliders 7 that are respectively slidably engaged with the two slide rails 6 on the mounting component 206, the mounting component 206 and the base 1 are stably assembled and move smoothly.

[0025] In this embodiment of the invention, the mounting member 206 has a mounting cavity 208, in which the lower punch 201 and the upper punch 202 are arranged vertically opposite each other, with the lower punch 201 positioned lower and the upper punch 202 positioned higher. This arrangement, by configuring the mounting cavity 208 on the mounting member 206 to accommodate the lower punch 201 and the upper punch 202, ensures stable assembly of the lower punch 201 and the upper punch 202 with the mounting member 206.

[0026] In this embodiment of the invention, the lower punch 201 is detachably and fixedly connected to the mounting member 206, and the stamping block 204 is detachably and fixedly connected to the upper punch 202. This configuration, by detachably and fixedly connecting the lower punch 201 to the mounting member 206 and the stamping block 204 to the upper punch 202, allows for changing the chamfer size by replacing the lower punch 201 and the stamping block 204, providing flexibility and good adaptability.

[0027] In this embodiment of the utility model, the mounting component 206 is provided with a cylinder 8 that drives the upper punch 202 to move up and down.

[0028] In this embodiment of the invention, the stamping hole 203 is a through hole extending vertically. The base 1 is provided with guide members 10 below each of the two stamping holes 203. The guide members 10 are inclined from top to bottom in a direction away from the other punching mechanism 2. This arrangement, by placing the guide members 10 below the stamping holes 203 and inclining them from top to bottom in a direction away from the other punching mechanism 2, facilitates the collection of waste materials.

[0029] In this embodiment of the invention, a displacement sensor 9 is provided on the base 1 next to a punching mechanism 2. By placing the displacement sensor 9 next to the punching mechanism 2, the above arrangement avoids the two punching mechanisms 2 from colliding due to excessive proximity or from being too far apart to punch out the cut corner.
