Description

[Technical Field]

[0001] This invention relates to the field of automation equipment technology, specifically an automatic punching head structure. [Background Technology]

[0002] When producing laptop casings, fan-shaped injection molding is used to meet the product appearance requirements. After the product is formed, the fan-shaped glue channels (i.e., the sprue) need to be removed in post-processing. Since the glue area of ​​the sprue is wide and numerous, it is difficult to break or cut it manually. Therefore, mechanical processing is usually used.

[0003] In the past, milling was mostly used to remove the sprue. However, due to the different properties of plastics compared to metals, plastics have poor thermal conductivity, low coefficient of thermal expansion, and low modulus of elasticity. When the clamp or tool applies too much pressure, it is easy to deform. They are also prone to melting when heated during cutting and tend to stick to the tool. When machining plastics, the tools and corresponding cutting speeds used must be adapted to the characteristics of plastics. Therefore, milling the sprue is time-consuming. At the same time, a large amount of waste is generated when milling the sprue, requiring frequent cleaning of the machine, which affects machine operation and production.

[0004] In view of this, it is necessary to invent an automatic punching head structure to directly cut off the material head, so that the material head can be recycled and reused, reducing the generation of waste, saving the time of cleaning the machine, improving the efficiency of machine use, shortening the processing time, and greatly increasing production capacity. [Summary of the Invention]

[0005] Therefore, the purpose of this invention is to provide an automatic punching head structure. Compared with the previous operation mode, this equipment can directly cut off the material head, reduce the generation of waste, save a lot of time cleaning the machine, improve the efficiency of machine use, shorten the processing time, and greatly increase the production capacity.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] An automatic punching head structure, characterized in that it comprises:

[0008] Base;

[0009] The positioning fixture is fixed on the base and has a support platform with a positioning boss. The product is placed on the support platform and positioned by the positioning boss.

[0010] The product fixing device is fixed on the support platform of the positioning fixture and located on one side of the positioning fixture. It is equipped with a driver and a pressure plate. The driver drives the pressure plate to move and fix the product.

[0011] The punching device is fixed on the base and located on one side of the positioning fixture. It is equipped with a driver and a punch. A stop block is provided below the punch. The driver drives the punch and the stop block to move. The stop block hits the material head, causing a crease to be made in the material head, while the punch cuts off the material head.

[0012] The material feeding chute is fixed on the base and located below the positioning fixture, serving to convey the material head.

[0013] Furthermore, the base includes a support frame and a U-shaped support plate, the support frame being fixedly connected to the U-shaped support plate, and the support platform of the positioning fixture being fixed to the U-shaped support plate by two foot pads.

[0014] Furthermore, the positioning boss is designed to be adjustable, and the holes used for fixing and connecting are designed to be keyway-shaped. By adjusting the position of the positioning boss, similar products can share a common positioning fixture.

[0015] Furthermore, the product fixing device is fixed to the support platform of the positioning fixture by a "Z"-shaped mounting block. The driver is fixed to the bottom of the "Z"-shaped mounting block. The pressure plate has connecting arms at both ends. One end of the connecting arm is fixedly connected to the pressure plate, and the other end is movably connected to the end of the driver. Connecting blocks are provided on both sides of the middle of the connecting arm. One end of the connecting block is movably connected to the middle of the connecting arm by a positioning pin, and the other end is movably connected to a boss by a positioning pin. The boss is located on the top of the "Z"-shaped mounting block. The driver drives the pressure plate to rotate around the boss as a fulcrum and press down to fix the product.

[0016] Furthermore, the punching device is equipped with a slide block, and the punch and the stop block are fixed on the slide block by a mounting block. The holes on the mounting block for fixing and connecting are designed as keyways to adjust the position of the punch and the stop block. The bottom of the slide block is provided with sliding grooves at both ends, which are respectively fitted into two slide rails. The two slide rails are respectively fixed to the "U"-shaped support plate of the base. The driver of the punching device is fixed to the "U"-shaped support plate by a mounting base. The end of the driver is fixedly connected to the slide block. The driver drives the stop block and the punch to move, thereby achieving the function of bending and cutting the material head.

[0017] Furthermore, at the opposite end of the product fixing device, there are two pressure blocks. One end of each pressure block is equipped with an adjusting screw, and the other end is fixedly connected to the end of a driver. The driver is fixed on the support platform. The driver drives the pressure blocks and adjusting screw to move, so that the adjusting screw abuts against the product, thereby assisting in fixing the product.

[0018] Furthermore, the actuator may be a cylinder.

[0019] Compared with existing technologies, the present invention provides an automatic punching head structure that directly cuts off the material head through punching. The material head automatically falls into the material chute, allowing it to be recycled. Compared with milling, punching reduces the generation of waste chips, saves a lot of time cleaning the machine, and improves the efficiency of machine use. At the same time, punching shortens the processing time compared with milling, greatly increasing production capacity. [Attached Image Description]

By adjusting the position of the positioning boss (210), similar products (10) can share the positioning fixture (2).

[0030] The product fixing device (3) is fixed on the support platform (200) of the positioning fixture (2) by a "Z"-shaped mounting block (300) and is located on one side of the positioning fixture (2). It is equipped with a driver (600) and a pressure plate (310). The driver (600) is fixed at the bottom of the "Z"-shaped mounting block (300). The driver (600) can be a cylinder. The driver (600) drives the pressure plate (310) to move and fix the product (10).

[0031] The punching device (4) is fixed on the base (1) and located on one side of the positioning fixture (2). It is equipped with a driver (600) and a punch (400). A stop block (401) is provided below the punch (400). The driver (600) drives the punch (400) and the stop block (401) to move. The stop block (401) abuts against the material head (11) to make a crease in the material head (11), while the punch (400) cuts off the material head (11).

[0032] The punching device (4) is provided with a slide (410). The punch (400) and the stop (401) are fixed on the slide (410) by a mounting block (402). The mounting block (402) has a keyway-shaped hole (403) for fixed connection, which allows for adjustment of the position of the punch (400) and the stop (401). The slide (410) has two grooves (411) at its bottom ends, which are respectively fitted into two slide rails (412). The two slide rails (412) are respectively fixed on the "U"-shaped support plate (110).

[0033] The driver (600) of the punching device (4) can be a cylinder, which is fixed on the "U" shaped support plate (110) by a mounting base (420). The end of the driver (600) is fixedly connected to the slide (410). The driver (600) drives the abutment (401) and the punch (400) to move, thereby achieving the functions of bending the material head (11) and cutting the material head (11).

[0034] The material drop chute (5) is fixed on the base (1) and located below the positioning fixture (2), serving to convey the material head (11).

[0035] In this embodiment, the pressure plate (310) is provided with connecting arms (320) at both ends. One end of the connecting arm (320) is fixedly connected to the pressure plate (310), and the other end is movably connected to the end of the driver (600). Connecting blocks (321) are provided on both sides of the middle part of the connecting arm (320). One end of the connecting block (321) is movably connected to the middle part of the connecting arm (320) through a positioning pin (322), and the other end is movably connected to a boss (301) through a positioning pin (322). The boss (301) is located on the top of the "Z"-shaped mounting block (300). The driver (600) drives the pressure plate (310) to rotate around the boss (301) and press down to fix the product (10).

[0036] In this embodiment, two pressure blocks (330) are provided opposite to the product fixing device (3). One end of the pressure block (330) is provided with an adjusting screw (331), and the other end is fixedly connected to the end of a driver (600). The driver (600) can be a cylinder, which is fixed on the support platform (200). The driver (600) drives the pressure block (330) and the adjusting screw (331) to move, so that the adjusting screw (331) abuts against the product (10), thereby fixing the product (10).

[0037] In summary, its workflow is as follows:

[0038] The product (10) with the material head (11) is placed on the support platform (200) and positioned by the positioning boss (210);

[0039] The driver (600) of the product fixing device (3) drives the pressure plate (310) to rotate around the boss (301) and press down to fix the product (10). At the same time, the pressure block (330) at the opposite position of the product fixing device (3) moves under the drive of the driver (600) and the adjusting screw (331). The adjusting screw (331) abuts against the product (10) to fix the product (10).

[0040] The driver (600) of the punching device (4) drives the punch (400) and the stop block (401) to move. The stop block (401) abuts against the material head (11), causing a crease to be formed on the material head (11), and the punch (400) cuts off the material head (11). The material head (11) automatically falls into the material drop trough (5).

[0041] The driver (600) of the punching device (4) drives the punch (400) and the stop block (401) to move back to their original positions. The driver (600) of the product fixing device (3) drives the pressure plate (310) to rotate and move back to its original position with the boss (301) as the fulcrum. At the same time, the pressure block (330) at the opposite position of the product fixing device (3) moves back to its original position with the adjusting screw (331) under the driving force of the driver (600). The above actions are repeated.

[0042] The above implementation method is quite reasonable. In actual work, this automatic punching structure directly cuts off the material head (11) through punching. The material head (11) automatically falls into the material drop trough (5), allowing the material head (11) to be recycled. Compared with milling, punching reduces the generation of waste chips, saves a lot of time cleaning the machine, and improves the efficiency of machine use. At the same time, compared with milling, taking the removal of the material head (11) of a product (10) as an example, punching takes 5 seconds plus 5 seconds of finishing, totaling 10 seconds; milling takes 24 seconds to mill the material head (11). Therefore, the processing time is shortened, and the production capacity is greatly improved.

[0043] The technical principles of the present invention have been described above with reference to specific embodiments. These descriptions are merely for explaining the principles of the invention and should not be construed as limiting the scope of protection of the invention in any way. Based on this explanation, those skilled in the art can conceive of other specific embodiments of the invention without creative effort, and these embodiments will all fall within the scope of protection of the present invention.
