Description

Technical Field

[0001] This utility model relates to the field of hardware bending technology, specifically a hardware product bending device. Background Technology

[0002] A bending device for hardware products is a mechanical device used for processing metal sheets or hardware products. It mainly applies pressure to the material through molds, power systems and transmission mechanisms, causing it to undergo plastic deformation to form a specific angle or shape. It is widely used in sheet metal processing, automotive parts, electronic device housings and other fields.

[0003] Chinese patent CN222740009U discloses a bending device for hardware products, including a worktable. A rotating cylinder is rotatably connected through the middle of the worktable. A driven gear is fixedly connected to the outer side of the rotating cylinder at the bottom of the worktable. A transmission shaft is rotatably connected to the bottom of the worktable. A pair of first brackets symmetrically arranged around the transmission shaft are fixedly connected to the bottom of the worktable. A first servo motor coaxial with the transmission shaft is fixedly connected to the bottom of the first brackets. A transmission gear meshing with the driven gear is fixedly connected to the outer side of the transmission shaft. This invention provides a bending device for hardware products to solve the problem that most existing hardware bending devices have fixed bending angles. If bending to different angles, it is necessary to replace the device or disassemble and replace it with a bending block of the corresponding angle. This process is not only time-consuming and labor-intensive, affecting work efficiency, but also increases production costs.

[0004] The above-mentioned device has the effect of quickly bending different angles, but the bending radius of the hardware products cannot be controlled during the use of the existing device, and it cannot be used when bending special hardware products. At the same time, the torque of the hardware products is large during the bending process, so it is necessary to fix one end of the hardware products. Therefore, a hardware product bending device is needed. Utility Model Content

[0024] Combination Figures 1-4A bending device for hardware products includes a base 1, on which a bending mechanism 2 is provided. The bending mechanism 2 includes a mounting plate 201, which is fixedly mounted on the upper part of the base 1. A fixed seat 202 is fixedly mounted through the middle of the mounting plate 201. Several positioning grooves 203 are fixedly mounted side by side on the fixed seat 202 and the mounting plate 201. An arc plate 204 is slidably mounted in each of the positioning grooves 203. A first bolt 205 is rotatably mounted on the lower part of the arc plate 204. A sliding groove 206 is provided on the mounting plate 201. A rotating seat 207 is fixedly mounted on the fixed seat 202. A bending arm 208 is rotatably mounted on the rotating seat 207. A bending plate 209 is fixedly mounted on the lower side of the bending arm 208. A limit frame 210 is fixedly mounted on one side of the fixed seat 202. A baffle 211 is slidably mounted inside the limit frame 210. A second bolt 212 is rotatably mounted on one side of the baffle 211.

[0025] Several positioning grooves 203 are each composed of several 1 / 4 annular grooves with progressively increasing inner diameters, and several arc plates 204 are adapted to different annular grooves. A rotating base 207 is located at the center of the positioning grooves 203 and the sliding groove 206. A bending plate 209 is embedded and slidably installed in the sliding groove 206. Several first bolts 205 are threaded onto the fixed base 202, and second bolts 212 are threaded onto the limiting frame 210. In use, the appropriate arc plate 204 is selected according to the bending radius required for hardware processing. By controlling the first bolts 205 on the lower side of the arc plate 204 to rotate it, the arc plate 204... The plate is lifted upwards and fully embedded into the positioning groove 203. The first bolt 205 on the lower side of the other arc plate 204 is controlled to make the arc plate 204 lower than the mounting plate 201. The bending plate 209 is rotated to the side of the limit frame 210 through the bending arm 208 to complete the initialization of the bending arm 208. The hardware product can then be passed through the limit frame 210 and the fixing seat 202. The second bolt 212 is further controlled to make the baffle 211 flush with the edge of the arc plate 204. At this time, the bending arm 208 is rotated to make the bending plate 209 press on the hardware product, so that the hardware product can be bent and the bending radius is consistent with the radius of the selected arc plate 204.

[0026] Example 2

[0027] See Figure 5 A fixing mechanism 3 is provided on the upper side of the mounting plate 201. The fixing mechanism 3 includes a support base 301, which is fixedly installed on the upper side of the mounting plate 201. A pressure plate 302 is slidably installed inside the support base 301. A third bolt 303 is rotatably installed on the upper side of the pressure plate 302. Several transverse grooves 304 are provided in parallel on the lower side of the support base 301, and several longitudinal grooves 305 are provided in parallel on the lower side of the pressure plate 302.

[0028] The support base 301 is flush with the limit frame 210. The third bolt 303 is threaded onto the support base 301. One end of the third bolt 303 is rotatably mounted on the middle of the pressure plate 302. The transverse groove 304 is perpendicular to the longitudinal groove 305. By inserting the hardware product between the support base 301 and the pressure plate 302, the third bolt 303 is further controlled to make the pressure plate 302 move downward. Benefiting from the fact that the lower side of the support base 301 has several transverse grooves 304 and the lower side of the pressure plate 302 has several longitudinal grooves 305, the hardware product is clamped by the support base 301 and the pressure plate 302 and cannot be detached.

[0029] In actual operation, the appropriate arc plate 204 is selected according to the bending radius required for the processing of the hardware products. By controlling the first bolt 205 on the lower side of the arc plate 204 to rotate, the arc plate 204 is lifted upward and fully embedded into the positioning groove 203. The first bolt 205 on the lower side of other arc plates 204 is controlled to make the arc plate 204 lower than the mounting plate 201. The bending plate 209 is rotated to the side of the limit frame 210 through the bending arm 208 to complete the initialization of the bending arm 208. The hardware products can then pass through the limit frame 210 and the fixing seat 202. The second bolt 212 is further controlled to make the baffle 211 flush with the edge of the arc plate 204. At this time, the bending arm 208 is rotated to make the bending plate 209 press on the hardware products, so that the hardware products can be bent and the bending radius is consistent with the radius of the selected arc plate 204.

[0030] By inserting the hardware product between the support base 301 and the pressure plate 302, and further controlling the third bolt 303 to move the pressure plate 302 downward, the hardware product is clamped by the support base 301 and the pressure plate 302 and cannot be detached because the support base 301 has several horizontal grooves 304 arranged in parallel on its lower side and the pressure plate 302 has several vertical grooves 305 arranged in parallel on its lower side.
