[0001] The invention relates to the technical field of steel grating plate processing, and more specifically, to a press for processing steel grating plates. Background Art

[0002] Steel grating plate forming machine (also called steel grating welding machine, steel grating automatic welding machine, etc.) is an automated equipment specially used for the production of steel grating plates. It is mainly used to weld flat steel (load-bearing flat steel) and twisted round steel (cross bar) together according to a certain spacing and arrangement to form a grid-like steel structure with certain strength and ventilation performance.

[0003] When punching flat steel, traditional presses can only leave holes on the flat steel for placing twisted round steel. However, the holes formed in this way cannot fix the twisted round steel in the holes. During welding, the contact between the welding gun head and the twisted round steel can easily cause it to be misaligned, which brings inconvenience to subsequent welding work and poor use effect. Summary of the invention

A first punching block for punching a metal sheet is fixedly mounted on one end of the mounting plate away from the hydraulic cylinder. An end of the support block close to the first punching block is in an arc-shaped structure. A second punching block for punching a metal sheet is fixedly mounted on one side of the mounting plate. A bending assembly is installed on one side of the second punching block, and the bending assembly extrude the punched metal sheet. The upper end of the second punching block is higher than the upper end of the metal sheet. A magnet is embedded in one end of the mounting plate, and the magnet attracts the punched metal sheet.

[0007] Furthermore, the two groups of the profiling assemblies are centrally symmetrically arranged, the two second punching blocks are in sliding contact on the side close to each other, and the two first punching blocks are in sliding contact on the side close to each other, and the support block and the extrusion block in the same profiling assembly are arranged opposite to each other.

[0008] Furthermore, a contraction groove is formed at one end of the second punching block, and the bending assembly includes an extrusion block slidably installed inside the contraction groove, and the extrusion block is elastically connected to the inside of the contraction groove through a connecting spring.

[0009] Furthermore, one end of the extrusion block is in an inclined structure, and the end of the extrusion block close to the mounting plate is parallel to the mounting plate, the end of the extrusion block close to the mounting plate is in extrusion contact with the stamped metal sheet, and the inclined part of the extrusion block is in extrusion contact with the metal sheet during the stamping process.

[0010] Furthermore, the inclined part of the extrusion block is provided with a plurality of movable grooves, and a plurality of baffles are slidably installed inside the movable grooves. The baffles are elastically connected to the movable grooves through return springs, and one end of the baffles away from the return spring is in extrusion contact with the surface of the metal sheet.

[0021] See also Figures 1 to 7A press machine for processing steel grating plates, comprising a plurality of hydraulic cylinders 101 mounted on a fixed frame 1, the number of the hydraulic cylinders 101 can be four, and two press assemblies 2 for press forming are arranged in the middle of the fixed frame 1; The profiling component 2 includes a mounting plate 201, which is fixedly connected to the moving end of one of the hydraulic cylinders 101. The profiling component 2 also includes a support block 203, which is fixedly connected to the other hydraulic cylinder 101. A first punching block 204 for punching a metal sheet is fixedly installed at one end of the mounting plate 201 away from the hydraulic cylinder 101. The end of the support block 203 close to the first punching block 204 is in an arc-shaped structure. A second punching block 3 for punching a metal sheet is fixedly installed on one side of the mounting plate 201. A contraction groove 301 is provided at one end of the second punching block 3. The bending component 4 includes an extrusion block 401 slidably installed inside the contraction groove 301. The extrusion block 401 is elastically connected to the inside of the contraction groove 301 through a connecting spring 402. A bending assembly 4 is installed on one side of the second punching block 3, and the bending assembly 4 extrude the punched metal sheet. The upper end of the second punching block 3 is higher than the upper end of the metal sheet. A magnet 205 is embedded at one end of the mounting plate 201, and the magnet 205 attracts the punched metal sheet. The two groups of profiling components 2 are arranged in a central symmetrical manner, the two second punching blocks 3 are in sliding contact on the side close to each other, and the two first punching blocks 204 are also in sliding contact on the side close to each other, and the support block 203 and the extrusion block 401 in the same profiling component 2 are arranged opposite to each other.

[0022] By adopting the above technical solution, the mounting plate 201 and the support block 203 are moved by controlling the hydraulic cylinder 101, wherein the support block 203 contacts the metal sheet first, and the hydraulic cylinder 101 controlling the movement of the support block 203 is no longer extended after being extended to the maximum. When the mounting plate 201 moves, the mounting plate 201 can drive the first punching block 204 and the second punching block 3 to move. When the support block 203 contacts the metal sheet, the mounting plate 201 can impact the metal sheet through the first punching block 204 and the second punching block 3, thereby cooperating with the arc-shaped part on the support block 203 to cut off part of the metal sheet to form a hole, wherein the two second punching blocks 3 can break the upper connection of the punched hole when punching. After the punching is completed, the hydraulic cylinder 101 is used to drive the support block 203 and the mounting plate 201 to move to the initial position. In this process, The mounting plate 201 is controlled to move, and when the mounting plate 201 moves to the initial position, the support block 203 is controlled to move. During the movement of the mounting plate 201, the mounting plate 201 can attract the fracture on the upper side of the metal sheet through the magnet 205, that is, near the stamping position of the two second stamping blocks 3. When the magnet 205 moves with the mounting plate 201, the fracture on the upper side of the metal sheet will be deformed, thereby forming a gap with the support block 203. With the movement of the mounting plate 201 and the second stamping block 3, the extrusion block 401 can extend from the shrinkage groove 301 under the action of the connecting spring 402, and extend into the gap between the metal sheet and the support block 203. With the movement of the second stamping block 3, the extrusion block 401 can extrude the vicinity of the fracture of the metal sheet, causing the metal sheet to deform. The simultaneous extrusion of the two extrusion blocks 401 can cause the two sides of the fracture of the metal sheet to deform in different directions.

[0023] One end of the extrusion block 401 is in an inclined structure, and the end of the extrusion block 401 close to the mounting plate 201 is parallel to the mounting plate 201, and the end of the extrusion block 401 close to the mounting plate 201 is in extrusion contact with the stamped metal sheet, and the inclined portion of the extrusion block 401 is in extrusion contact with the metal sheet during the stamping process; The inclined part of the extrusion block 401 is provided with a plurality of movable grooves 403, and a plurality of baffle rods 404 are slidably installed inside the movable grooves 403. The baffle rods 404 are elastically connected to the inside of the movable grooves 403 through return springs 405, and one end of the baffle rods 404 away from the return springs 405 is in extrusion contact with the surface of the metal plate.

[0024] By adopting the above technical solution, when the second punching block 3 punches the metal plate, the metal plate will contact the end of the blocking rod 404, thereby squeezing the blocking rod 404, causing it to squeeze the return spring 405 and shrink into the movable groove 403. After that, the metal plate can squeeze the inclined part on the extrusion block 401, so that the extrusion block 401 shrinks into the shrinkage groove 301 under the action of the decomposition force of the extrusion force, so that the second punching block 3 can drive the extrusion block 401 to move to the other side of the metal plate. After the extrusion block 401 passes over the metal plate to the other side, the extrusion block 401 will retract from the shrinkage groove 301 again under the action of the connecting spring 402. The second punching block 304 is provided with a plurality of movable grooves 403 and a plurality of movable grooves 403 for supporting the metal sheet. The movable grooves 403 are provided with a plurality of movable grooves 403 for supporting the metal sheet. The movable grooves 403 are provided with a plurality of movable grooves 403 for supporting the metal sheet. The movable grooves 403 are provided with a plurality of movable grooves 403 for supporting the metal sheet.

[0025] A third punching block 206 is fixedly mounted on one side of the mounting plate 201 away from the second punching block 3. The upper end of the third punching block 206 is higher than the upper end of the metal plate. The first punching block 204 is located between the second punching block 3 and the third punching block 206. There is a gap between the end of the first punching block 204 away from the mounting plate 201 and the extrusion block 401. A notch 207 is formed at a position corresponding to the support block 203 and the third punching block 206 , and the size of the third punching block 206 matches the size of the notch 207 .

[0026] By adopting the above technical solution, when the mounting plate 201 moves to drive the first punching block 204 to punch the metal sheet, the third punching block 206 will move with the movement of the mounting plate 201. After the third punching block 206 moves, it can punch the metal sheet and cooperate with the notch 207 to cut a fracture in the metal sheet, so that the upper side of the hole in the metal sheet can be bent more easily, and the impact on other positions during deformation can be reduced to avoid deformation of other parts.

[0027] A flame head 208 is fixedly installed on the mounting plate 201 at a position relative to the lower side of the third stamping block 206. The flame head 208 is connected to a fuel supply device through a pipe 209, wherein the fuel supply device may be an oxygen tank or other device containing combustible gas. When the mounting plate 201 is about to move to drive the first stamping block 204, the second stamping block 3, and the third stamping block 206 to move, the flame head 208 burns to heat the metal sheet, and the heating position is the position on the lower side of the third stamping block 206, so that this part of the metal sheet is softened. When the extrusion block 401 extrude the metal sheet to deform it, the metal sheet will deform preferentially from the heating position, reducing the impact on other positions, thereby avoiding deformation of other positions due to the extrusion of the extrusion block 401.
