Description

Technical Field

[0001] This utility model relates to the field of metal processing technology, and more specifically to a shearing device for producing U-shaped buckles. Background Technology

[0002] U-shaped clips, as a multifunctional mechanical connection device, are widely used in various fields for fixing, connecting, and protecting devices due to their structural characteristics and material compatibility. After bending, U-shaped clips require excess material to be cut off. However, existing U-shaped clip cutting methods involve cutting directly from one side of the clip. Because the upper end of the U-shaped clip is suspended, it shifts with the cutter during the cutting process due to the lack of support, affecting the cutting effect and precision. Utility Model Content

[0004] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows.

[0005] A shearing device for producing U-shaped buckles includes a cutting table with a lower cutting die for placing and cutting the U-shaped buckles. The lower cutting die has a positioning groove along the running direction of the U-shaped buckles for positioning them. A cutting groove perpendicular to the positioning groove is laterally formed in the middle of the lower cutting die. Support plates are vertically arranged on the cutting tables on the left and right sides of the lower cutting die. A crossbeam is provided at the top of the support plate, and a lifting plate is provided at the lower end of the crossbeam via a lifting cylinder. A cutter corresponding to the cutting groove on the lower cutting die is laterally arranged in the middle of the lifting plate. Pressure blocks for pressing and fixing the U-shaped buckles in the positioning groove are provided on the lifting plates on both sides of the cutter. A cutting cylinder for driving the cutter to move up and down is provided at the bottom of the lifting plate.

[0006] To further optimize the technical solution, two guide rods are installed between the cutting table and the lifting plate to guide the movement of the lifting plate.

[0007] To further optimize the technical solution, limit blocks are respectively provided on the guide rods on the upper and lower sides of the lifting plate to limit the movement position of the lifting plate.

[0008] To further optimize the technical solution, the cutter is mounted on the telescopic rod of the cutting cylinder via a cutter holder.

[0009] To further optimize the technical solution, a slag collection trough is provided in the cutting table below the cutting groove for collecting cutting residue. A handle is provided on the side of the slag collection trough to facilitate pulling the slag collection trough out of the cutting table.

[0010] To further optimize the technical solution, a spring-loaded mechanism is provided on the bottom surface of the positioning groove along the running direction of the U-shaped buckle to support the cut U-shaped buckle for easy rearward transmission.

[0011] To further optimize the technical solution, the pop-up mechanism includes a groove formed on the bottom end face of the positioning groove, and spring extension grooves are respectively formed on both sides of the bottom end of the groove.

[0019] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0020] A shearing device for producing U-shaped buckles, combined with Figures 1 to 4As shown, it includes a cutting table 1, on which a lower cutting mold 2 is provided for placing U-shaped buckles for cutting. The lower cutting mold 2 has a positioning groove 3 along the running direction of the U-shaped buckle for positioning the U-shaped buckle. A cutting groove 16 is provided laterally in the middle of the lower cutting mold 2, and the cutting groove 16 is perpendicular to the positioning groove 3.

[0021] Support plates 4 are respectively installed on the cutting tables 1 on the left and right sides of the lower cutting mold 2. A crossbeam 5 is installed at the top of the support plate 4. A lifting plate 7 is installed at the lower end of the crossbeam 5 via a lifting cylinder 6. A cutter 8 is horizontally installed in the middle of the lifting plate 7. The cutter corresponds to the cutting groove on the lower cutting mold and is used to cut the U-shaped buckles on the lower cutting mold. Pressure blocks 9 are respectively installed on the lifting plates 7 on the front and rear sides of the cutter 8. The pressure blocks 9 are used to press and fix the U-shaped buckles placed in the positioning groove. A cutting cylinder 14 is installed on the lifting plate 7 to drive the cutter to move up and down to cut the U-shaped buckles. The cutter 8 is mounted on the telescopic rod of the cutting cylinder via a cutter seat 15, which allows the cutter to be replaced during use to ensure the cutting effect.

[0022] Two guide rods 10 are provided between the cutting table 1 and the lifting plate 7. The guide rods pass through the lifting plate 7 and are used to guide the vertical movement of the lifting plate 7. Limit blocks 11 are provided on the guide rods 10 on the upper and lower sides of the lifting plate 7 to limit the movement of the lifting plate.

[0023] A slag collection trough 12 is provided in the cutting table 1 below the cutting groove 16 to collect cutting residue. A handle 13 is provided on the side of the slag collection trough to pull the slag collection trough out of the cutting table.

[0024] A pop-up mechanism is provided on the bottom surface of the positioning groove 3. The pop-up mechanism is set along the running direction of the U-shaped buckle and is used to support the cut U-shaped buckle so that it can be transported to the rear.

[0025] The spring-lifting mechanism includes a groove 17 formed on the bottom end face of the positioning groove 3. The bottom end of the groove 17 is provided with spring sheet telescopic grooves 18 on both sides. A spring sheet 19 is provided in the groove 17 and extends into the spring sheet telescopic groove. A spring 20 is provided in the spring sheet telescopic groove to support the spring sheet. After the U-shaped buckle is cut, the spring sheet supports the U-shaped buckle to lift upward at the moment the pressure block is raised, so as to prevent the U-shaped buckle from being stuck in the positioning groove and facilitate the rearward conveying.

[0026] In this invention, when cutting a U-shaped buckle, the U-shaped buckle is conveyed into the positioning groove of the cutting lower mold. The lifting cylinder drives the lifting plate to move downward, and the lifting plate drives the pressure block to move downward to press and support the U-shaped buckle. After the U-shaped buckle is pressed, the cutting cylinder pushes the cutter downward to cut the U-shaped buckle. After the cutting is completed, the cutting cylinder resets, and the lifting cylinder drives the pressure block to move upward. After the pressure block disengages from the U-shaped buckle, the pressure on the U-shaped buckle decreases, and the spring sheet bounces upward under the action of the bottom spring, lifting the U-shaped buckle for easy transport to the rear.

[0027] The residue generated during the cutting process is collected through the slag collection trough at the bottom, which avoids contaminating the workshop and facilitates cleaning.
