Abstract
Description
Technical Field
[0001] This utility model relates to a cold bending machine for forming angle steel, and belongs to the technical field of cold bending machines. Background Technology
[0002] Angle steel, also known as angle iron, is a long strip of steel with two sides perpendicular to each other, forming an angle. It can be divided into two categories: equal-sided angle steel and unequal-sided angle steel. Equal-sided angle steel has two sides of equal width, while unequal-sided angle steel has two sides of unequal width. Cold bending machines are used in the processing of angle steel.
[0003] Chinese Patent Publication No. CN 211277357 U discloses a cold bending machine for forming angle steel. The cold bending machine includes a frame, a cold bending assembly, a cutting assembly, and a guiding assembly. Both the cutting assembly and the guiding assembly are mounted on the frame. The cold bending assembly bends the workpiece to be bent, and the guiding assembly guides the bent workpiece to the cutting assembly, which cuts the bent workpiece. The cold bending assembly includes a cold bending group mounted on the frame, comprising an upper roller, a lower roller, and a cold bending roller. The outer circumference of the upper roller has upper embossing, and the outer circumference of the lower roller has lower embossing. The cold bending roller bends the workpiece, and the upper and lower embossing work together to imprint embossing on the surface of the workpiece, thereby improving its strength. This invention provides a cold bending machine for forming angle steel, where the upper and lower embossing work together to ensure that the embossing on the workpiece is identical, guaranteeing the processing accuracy and quality of the workpiece.
[0004] The above-mentioned device mainly relies on upper and lower rollers to transport angle steel. However, there are many different sizes of angle steel. When the size of the angle steel changes, the upper and lower rollers may not be able to transport and cold bend the angle steel, which will affect the final forming of the angle steel. This makes the equipment less flexible to use and inconvenient for operators.
[0005] Therefore, a cold bending machine for forming angle steel is proposed. Utility Model Content

[0027] In the following description, only certain exemplary embodiments are briefly described.

Therefore, the drawings and description are considered exemplary in nature and not restrictive.
[0028] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.
[0029] Example 1
[0030] like Figure 1-5As shown, this utility model embodiment provides a cold bending machine for forming angle steel, including a base plate 1. An electric roller conveyor 4 is fixedly installed on the top of the base plate 1. A cold bending device 5 is fixedly installed on the left side of the top of the base plate 1. A hydraulic cylinder 6 is fixedly installed on the top of the cold bending device 5. A punch head 7 is fixedly installed at the bottom of the hydraulic cylinder 6. A mounting frame 3 is fixedly installed on the top of the base plate 1. An adjustment mechanism 2 is provided on the surface of the mounting frame 3. The adjustment mechanism 2 includes a bidirectional motor 201, a driven bevel gear 204, and a second connecting rod 207. The bidirectional motor 201 is located on the left side of the top of the mounting frame 3. Both driven bevel gears 204 are located on the left side of the top of the mounting frame 3. Six second connecting rods 207 are located on the front and rear sides of the top of the mounting frame 3. The bottom ends of the six second connecting rods 207 are movably connected to a moving plate 208. A slider 209 is fixedly installed at the bottom of each of the six moving plates 208. Each of the six sliders 209 has a movable rod 210 movably connected to its bottom. Each of the six movable rods 210 has a frame 211 movably connected to its bottom. Each of the frames 211 has a lower pressure roller 212 movably connected to its inner side. A bidirectional motor 201 is fixedly installed on the left side of the top of the mounting frame 3. Each of the output ends of the bidirectional motor 201 on both the front and rear sides has a connecting rod 202 fixedly installed. Each of the two connecting rods 202 has a driving bevel gear 203 fixedly installed on its outer side. The surface of the driving bevel gear 203 meshes with the surface of the driven bevel gear 204. Each of the two driven bevel gears 204 is movably connected to the left side of the top of the mounting frame 3. Each of the two driven bevel gears 204 has a mounting rod 205 fixedly installed on its right side. Each of the two mounting rods 205 has a first connecting rod 206 fixedly installed on its surface. Each of the six first connecting rods 206 is movably connected to the other end of each of the six second connecting rods 207.
[0031] By setting the adjustment mechanism 2, the output of the bidirectional motor 201 causes the first connecting rod 206 to drive the slider 209 to move inward. At this time, the frame 211 drives the lower pressure roller 212 to press down on the angle steel. By adjusting the height of the lower pressure roller 212, it can cooperate with the electric roller conveyor 4 to press down and limit angle steel of different thicknesses, while also preventing the angle steel from shifting during transmission. This saves the operator the steps of transporting materials by themselves, improves the convenience and efficiency of equipment use, and makes it easier for operators to use.
[0032] Example 2
[0033] like Figure 4-6As shown, in one embodiment, the top of the mounting frame 3 is provided with a moving groove 215, and six moving plates 208 pass through the inner cavity of the three moving grooves 215 and extend to the bottom of the mounting frame 3. The bottom of the mounting frame 3 is fixedly installed with a sliding rod 214, and six sliders 209 are slidably connected to the front and rear sides of the three sliding rods 214. The left and right sides of the bottom of the mounting frame 3 are fixedly installed with guide rods 213, and the frame 211 is slidably connected to the surface of the four guide rods 213. The surface of the two connecting rods 202 is movably connected with a support block 216 through a bearing. The bottom of the two support blocks 216 is fixedly installed on the left side of the top of the mounting frame 3. The left and right sides of the surface of the base plate 1 are threaded with anchor bolts 8, and the bottom of the four anchor bolts 8 is threaded to the ground.
[0034] By setting the moving groove 215, the movement of the moving plate 208 can be limited to prevent it from deviating during movement. By setting the sliding rod 214, the movement of the slider 209 can be limited to prevent it from changing direction during movement. By setting the guide rod 213, the movement of the frame 211 can be limited to improve the guiding performance of the frame 211 during movement. By setting the support block 216, the connecting rod 202 can be supported to improve its load-bearing capacity. By setting the anchor bolts 8, the overall equipment can be stabilized to prevent accidental collisions from affecting the cold bending of the angle steel.
[0035] In operation, the angle steel is placed on top of the electric roller conveyor 4 according to its thickness. Then, through the output of the bidirectional motor 201, the connecting rod 202 drives the active bevel gear 203 to rotate. At this time, the active bevel gear 203 and the driven bevel gear 204 cooperate to install the mounting rod 205, which drives the first connecting rod 206 to swing. At this time, the second connecting rod 207, through the cooperation of the first connecting rod 206, drives the moving plate 208 and the slider 209 to move outward. Due to the change in the position of the slider 209, the movable rod 210 swings and drives the frame 211 and the lower pressure roller 212 to move downward. The lower pressure roller 212 presses down and limits the angle steel on the electric roller conveyor 4. The angle steel is transported to the inside of the cold bending device 5 through the electric roller conveyor 4, and the pressing head 7 is pressed down by the oil cylinder 6 to complete the cold bending of the angle steel.
[0036] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any person skilled in the art can easily conceive of various variations or substitutions within the technical scope disclosed in this utility model, and these should all be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
