Description

Technical Field

[0001] This utility model relates to the field of hardware technology, and in particular to a punching and burr removal device for hardware processing. Background Technology

[0002] With the transformation and upgrading of the manufacturing industry and the acceleration of urbanization, the market demand for hardware products continues to grow, and the hardware industry has broad development prospects. Hardware refers to tools made of metals such as gold, silver, copper, iron, and tin through processing and casting, used for fixing, processing, decoration, etc., and has a wide range of applications. There are many types of hardware, including but not limited to building hardware, automotive repair hardware, daily hardware, and industrial repair hardware.

[0003] After punching some hardware parts, the hardware parts are subjected to the shearing force of the punch, and some burrs appear at the edge of the punch, which will have a certain impact on subsequent use and packaging. Based on this, a punching burr treatment device for hardware parts processing is proposed to grind the burrs around the punching of hardware parts. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the prior art and provide a punching burr removal device for hardware processing, which effectively solves the deficiencies of the prior art.

[0005] To achieve the above objectives, one embodiment of this utility model provides a punching and deburring device for metal parts processing, including a base. Pneumatic cylinders are symmetrically mounted on both sides of the top surface of the base, and a horizontal frame is mounted on the output ends of both cylinders. Support rods are mounted on both sides of the top surface of the horizontal frame, and a mold base is mounted between the tops of the four cylinders. Both sides of the mold base are bent upwards in opposite directions. One side of the top surface of the base is raised upwards, and a vertically placed drive motor is mounted on its top. A grinding wheel and flange bolts are mounted on the output end of the drive motor. A through hole for the grinding wheel and flange bolts to pass through is provided in the middle of the top surface of the mold base.

[0006] Preferably, in any of the above solutions, a vertically placed guide tube is installed in the middle of the top surface of the base, and through grooves are symmetrically opened on its outer wall. A guide column that cooperates with the guide tube is installed in the middle of the bottom surface of the transverse frame. By using this solution, it is convenient to guide the vertical movement of the transverse frame, avoid the transverse force from acting directly on the two pneumatic cylinders, and achieve protection of the pneumatic cylinders. At the same time, the grooved treatment on the outer wall of the guide tube allows air to freely enter and exit when the guide column moves up and down inside the guide tube, ensuring the smooth operation of the guide column.

[0007] Preferably, in any of the above solutions, two limiting holes are provided in the middle of the top surface of the transverse frame, and a waste collection trough is provided on the top surface of the transverse frame. The bottom surface of the waste collection trough is equipped with limiting posts that cooperate with the limiting holes. By using this solution, the waste collection trough can be stably placed on the top surface of the transverse frame. The limiting posts cooperate with the limiting holes to prevent the waste collection trough from sliding accidentally. At the same time, the two sides of the transverse frame are respectively attached to the sides of the support rod, and the other two sides protrude from the transverse frame, thereby realizing the collection and holding of burr metal chips.

[0008] Preferably, the top of each of the four support rods on adjacent sides is provided with a protrusion, and the sides of the four support rods that are far apart are fixedly connected to the two sides of the mold base by bolts. This solution facilitates the support of the mold base. During the installation of the mold base, it is convenient to place the mold base directly on the top surface of the protrusion, and then it is convenient to use bolts to fix the mold base to the top of the support rod.

[0009] Preferably, one end of the mold base is equipped with two blocking blocks with a gap between their adjacent sides. Guide blocks are installed at the two corners of the mold base away from the top surface of the blocking blocks. The blocking blocks in this scheme facilitate the placement and blocking of the hardware parts, and make it easy to align the punching position of the hardware parts with the position of the grinding wheel. Then, with the synchronous extension of the two pneumatic cylinders, the grinding wheel enters the punching position, which facilitates the grinding of the punching burrs. At the same time, the stepped structure of the grinding wheel makes it easy to punch the inside of the hole at the bottom of the grinding wheel, ensuring the stability of the grinding process.

[0010] Preferably, in any of the above solutions, a limiting ring is installed at the output end of the drive motor. The bottom of the output end of the drive motor is hexagonal prism in shape, and the outer diameter of the limiting ring is smaller than that of the grinding wheel and the flange bolt. In this solution, the limiting ring can block the installation position of the grinding wheel. At the same time, the hexagonal prism structure of the output end of the drive motor is used for power transmission to prevent the grinding wheel from slipping. The flange bolt is threadedly connected to the output end of the drive motor, thereby achieving the locking of the grinding wheel.

[0011] Preferably, as described in any of the above solutions, a transparent protective plate is installed on the side of the base near the top of the drive motor. This solution allows the bottom of the transparent protective plate to be close to the hardware during the synchronous lifting of the horizontal frame and the hardware, thus providing some protection for the operator. At the same time, the use of transparent material makes it convenient for the operator to observe the entire grinding process.

[0012] This utility model has the following advantages: 1. This punching and deburring device for metal parts processing consists of a base, two pneumatic cylinders, a horizontal frame, a mold base, a drive motor, and a grinding wheel. The two sides of the horizontal frame are connected to the output ends of the pneumatic cylinders. The drive motor is placed vertically, and the grinding wheel is installed at the output end of the drive motor. When the metal part is placed inside the mold base, the two pneumatic cylinders extend synchronously, pushing the metal part vertically upward and allowing the grinding wheel to enter the punching hole of the metal part. As the drive motor rotates, it facilitates the grinding of burrs around the punching hole. The overall structure is simple and reasonable, making it easy to promote and use.

[0013] 2. This punching and deburring device for hardware processing, by setting a base, guide pillars and guide tubes, with the guide pillars and guide tubes slidably connected, facilitates the vertical movement of the horizontal frame. By setting two blocking blocks, the placement position of the hardware parts is limited, and a gap is left between the two to allow burrs to be discharged in time. By setting two guide blocks, the hardware parts are guided into the mold base, improving the convenience of operation and making it easier for operators to use. Attached Figure Description
