[0026] Embodiment 1

[0027] Referring to Figure 1 , this is the first embodiment of the present utility model, which provides a metal sheet bending device. This device includes a support assembly 100 and a bending assembly 200. Among them, the support assembly 100 includes a base 101 and a bracket 102 provided on the base 101; the bending assembly 200 is provided on the base 101 and includes a telescopic cylinder 201, a pressing block 202 connected to the telescopic cylinder 201, a first spring 203 and a slider 204 provided in the pressing block 202, a bending block 205 and a second spring 206 provided on the base 101.

[0028] Among them, a semi-cylindrical groove 101a is formed in the center of the base 101. The bracket 102 is fixedly arranged on the base 101, and the telescopic cylinder 201 is fixedly arranged on the bracket 102. The telescopic end of the telescopic cylinder 201 is fixedly provided with the extrusion block 202. A sliding cavity 202a is formed in the center of the extrusion block 202, and sliding grooves 202b are symmetrically formed on the side wall of the extrusion block 202. A sliding rod 204a is fixed on the slider 204. The slider 204 is slidably connected to the extrusion block 202. The sliding rod 204a is arranged in the sliding groove 202b. The first spring 203 is arranged in the sliding cavity 202a. One end of the first spring 203 is fixedly connected to the inner wall of the sliding cavity 202a, and the other end is fixedly connected to the slider 204. A round rod 204b is fixed to the bottom of the slider 204. The bending block 205 is slidably connected to the base 101. The bending blocks 205 are symmetrically arranged on both sides of the base 101, and a limiting rod 205a is further arranged on the bending block 205. There are two limiting rods 205a, and a limiting ring 205b is further arranged on the limiting rod 205a. The limiting rod 205a is slidably connected to the base 101. The second spring 206 is sleeved outside the limiting rod 205a. One end of the second spring 206 is fixedly connected to the limiting ring 205b, and the other end is fixedly connected to the outer wall of the base 101. A quarter-cylindrical groove is further formed in the bending block 205, a square groove is further formed in the bending block 205, an inclined surface 205c is further formed in the bending block 205, and pointed corners 202c are symmetrically arranged on both sides of the extrusion block 202. The pointed corners 202c can be attached to the inclined surface 205c.

[0029] During the use process, place the metal sheet in the square groove of the bending block 205 to prevent it from moving. Start the telescopic cylinder 201. The extrusion block 202 is pressed down by the telescopic cylinder 201, driving the internal slider 204 to press down. When the round rod 204b releases the metal sheet, the telescopic cylinder 201 continues to extend, causing the round rod 204b to bend the metal sheet until the round rod 204b contacts the inner wall of the semi-cylindrical groove 101a of the metal sheet. The telescopic cylinder 201 continues to press down, compressing the first spring 203. The slider 204 does not move due to the influence of the base 101. The extrusion block 202 and the slider 204 form relative movement, and the sliding rod 204a moves relatively in the sliding groove 202b until the pointed corners 202c on the extrusion block 202 contact the inclined surface 205c. When the extrusion block 202 continues to press down, it will tighten the two bending blocks 205 inward and compress the second spring 206 through the inclined surface 205c. Since the two bending blocks 205 slide and tighten towards each other, the two sides of the metal sheet can be bent. Through the quarter-cylindrical groove on the bending block 205, the two sides of the metal sheet are pushed to be attached to the round rod 204b, thereby bending the metal sheet into a cylindrical shape. Then the telescopic cylinder 201 retracts, and the device is reset to the initial state through the first spring 203 and the second spring 206. The subsequent movement process is the same as the above.

[0030] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit them. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the spirit and scope of the technical solutions of the present invention, and they should all be covered by the scope of the claims of the present invention.
