Description

Technical Field

[0001] This utility model belongs to the field of angle steel material production, and in particular relates to a clamping structure for conveying angle steel through punching. Background Technology

[0002] Angle steel, commonly known as angle iron, is a long strip of steel with two sides perpendicular to each other, forming an angle. It is divided into equal-sided angle steel and unequal-sided angle steel. Angle steel can be used to form various load-bearing components according to different structural needs, and can also be used as connecting parts between components, widely used in various building structures and engineering structures. In the processing of angle steel, angle steel punching machines are often used to drill holes to support standard production parts. However, during the drilling operation, the angle steel to be drilled needs to be manually fed into the punching machine, which is labor-intensive. If a hydraulic cylinder or lead screw module is used to push the angle steel end for feeding, the trajectory of the angle steel is difficult to control during the pushing process, and the pushing end is in a slack state, which can easily lead to angular deviation. Utility Model Content

[0003] In view of this, the present invention aims to propose a clamping structure for conveying angle steel during drilling, so as to solve the problems of high manual feeding intensity and low efficiency, unstable feeding angle due to the use of linear module for feeding, and easy deviation of the pushing end when feeding angle steel during drilling.

[0004] To achieve the above objectives, the technical solution of this utility model is implemented as follows:

[0005] A clamping structure for conveying perforated angle steel includes a pushing assembly and a linear module. The linear module can slide axially along a third frame. The pushing assembly is installed at the movable end of the linear module. The pushing assembly includes a cantilever and a clamp. The cantilever is installed at the movable end of the linear module. One end of the cantilever is provided with a clamping groove, and the clamp is provided opposite to the clamping groove. One end of the clamp is fixedly connected to the movable end of a third push rod cylinder. An alignment plate is installed on the cantilever. The third push rod cylinder is installed at one end of the alignment plate, and a fourth push rod cylinder is installed at the other end of the alignment plate. A limit plate is installed at the movable end of the fourth push rod cylinder. A buffer plate is elastically provided on one side of the limit plate. A position trigger switch is provided on the limit plate. One end of the angle steel to be clamped can abut against one end of the buffer plate, and the other end of the buffer plate can touch the execution end of the position trigger switch.

[0006] Furthermore, the alignment plate has an L-shaped structure.

[0007] Furthermore, the lower ends of the limiting plate and the buffer plate are slidably connected to the clamping groove, respectively.

[0008] Furthermore, the limiting plate is provided with multiple guide holes, and multiple guide rails are installed on one end of the buffer plate. The periphery of each guide rail is slidably connected to a guide hole, and a buffer spring is provided on the periphery of the guide rail. The two ends of the buffer spring are respectively fixedly connected to one end of the limiting plate and one end of the buffer plate.

[0009] Furthermore, the clamping structure for conveying the angle steel during punching also includes a rotating plate and a first push rod cylinder. The third frame is fixedly installed on the foundation. A linear module is set on one side of the third frame, and multiple material supports are set along the axial direction on the other side of the third support. The rotating plate is rotatably mounted on the moving end of the linear module. One end of the first push rod cylinder is rotatably connected to one side of the rotating plate, and the other end of the first push rod cylinder is rotatably connected to the moving end of the linear module. A pushing assembly is set on the rotating plate, and the actuating end of the pushing assembly can push the angle steel material to slide on the material supports.

[0010] Furthermore, the limiting plate is provided with a limiting sliding hole, and a limiting sliding rod is slidably arranged in the limiting sliding hole. One end of the limiting sliding rod is provided with a positioning touch switch, and a first spring is provided on the periphery of the limiting sliding rod. The two ends of the first spring are respectively fixedly connected to the inner side of the limiting plate and the periphery of the limiting sliding rod.

[0011] Furthermore, two adjusting plates are provided on the lower side of the rotating plate, and the two adjusting plates are arranged parallel to each other. The periphery of the cantilever is located between the two adjusting plates. Adjusting bolts are threaded to both sides of one end of the cantilever. Each adjusting plate is provided with an elongated hole, and the periphery of the adjusting bolt can slide within the elongated hole. The adjusting bolt is used to fix the relative position between the cantilever and the rotating plate.

[0012] Furthermore, the punching device is located between the material conveying device and the unloading conveying device, and a baffle plate is installed on the material support away from the punching device. The baffle plate does not interfere with the movement of the cantilever, and one end of the angle steel material can abut against one side of the baffle plate.

[0013] Compared with the prior art, the clamping structure for conveying perforated angle steel described in this utility model has the following advantages: the buffer plate can limit the position of the end of the angle steel material relative to the clamping groove. When the end of the angle steel material is pressed against the buffer plate, it means that the end of the angle steel material is in the fixed position. It can be detected by the position trigger switch so that the clamping block can clamp the angle steel. It is controlled by a mechanical switch, which has high reliability and simple operation.

[0023] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0024] like Figs. 1-3 As shown, the clamping structure for conveying perforated angle steel includes a third frame, a linear module 1, a rotating plate 2, a first pusher cylinder 3, and a pushing assembly 4. The third frame is fixedly installed on the foundation. The linear module 1 is installed on one side of the third frame, and multiple material supports 5 are installed axially on the other side of the third frame. The rotating plate 2 is rotatably mounted on the moving end of the linear module 1. One end of the first pusher cylinder 3 is rotatably connected to one side of the rotating plate 2, and the other end of the first pusher cylinder 3 is rotatably connected to the moving end of the linear module 1. The pushing assembly 4 is installed on the rotating plate 2. The actuator can push the angle steel material to slide on the material support 5. The linear module 1 is a lead screw module of the prior art. The linear module 1 can drive the rotating plate 2 to slide along the axial direction of the angle steel material. The rotating plate 2 is equipped with a first push rod cylinder 3. The two ends of the first push rod cylinder 3 are rotatably connected to the rotating plate 2 and the linear module 1, respectively. The first push rod cylinder 3 is used to change the relative angle between the moving ends of the rotating plate 2 and the linear module 1. A pushing component 4 is provided on the rotating plate 2. By changing the relative angle of the rotating plate 2, the pushing component 4 can be moved closer to or away from the material support 5.

[0025] The material pushing assembly 4 includes a cantilever 41 and a clamp 42. The cantilever 41 is fixedly mounted on the rotating plate 2. One end of the cantilever 41 is provided with a clamping groove 43, and the clamp 42 is arranged opposite to the clamping groove 43. One end of the clamp 42 is fixedly connected to the movable end of the third push rod cylinder 44, and the third push rod cylinder 44 is fixedly mounted on the cantilever 41. The third push rod cylinder 44 is existing technology. The third push rod cylinder 44 can push the clamp 42 to clamp with the clamping groove 43, thereby achieving the purpose of fixing the end of the angle steel material. Furthermore, an alignment plate 45 is installed on the cantilever 41. The alignment plate 45 has an L-shaped structure. A third push rod cylinder 44 is installed at one end of the alignment plate 45, and a fourth push rod cylinder 46 is installed at the other end. A limiting plate 47 is installed on the movable end of the fourth push rod cylinder 46, and the lower end of the limiting plate 47 is slidably connected to the clamping groove 43. A buffer plate 6 is elastically provided on one side of the limiting plate 47, and a positioning touch switch 49 is provided on the limiting plate 47. One end of the angle steel to be clamped can abut against the buffer plate 6. One end of the buffer plate 6 can touch the execution end of the position-activated switch 49. The buffer plate 6 is used to limit the relative position of the end of the angle steel material on the clamping groove 43. When the end of the angle steel material is pressed against the buffer plate 6, it means that the end of the angle steel material is fixed in place. A limiting sliding hole is provided on the limiting plate 47, and a limiting sliding rod is slidably arranged in the limiting sliding hole. The position-activated switch 49 is provided at one end of the limiting sliding rod, and a first spring 48 is provided on the periphery of the limiting sliding rod. The two ends of the first spring 48 are respectively fixedly connected to the inner side of the limiting plate 47 and the periphery of the limiting sliding rod. The position-activated switch 49 is a micro switch of the prior art. When the end of the angle steel material touches the buffer plate 6, the buffer plate 6 elastically retracts until it abuts the position-activated switch 49. The position-activated switch 49 detects the position information of the angle steel material, and the position-activated switch 49 can slide with the limiting sliding rod to prevent hard impact from damaging the parts. The spring can reset and rebound the relative position of the position-activated switch 49.

[0026] like Fig. 3 As shown, the limiting plate 47 is provided with multiple guide holes, and multiple guide rails 61 are installed on one end of the buffer plate 6. The periphery of each guide rail 61 is slidably connected to a guide hole, and a buffer spring 62 is provided on the periphery of the guide rail 61. The two ends of the buffer spring 62 are respectively fixedly connected to one end of the limiting plate 47 and one end of the buffer plate 6. Through the cooperation of the guide rail 61 and the guide hole, the sliding trajectory of the buffer plate 6 is limited, and the buffer spring 62 can elastically reset the relative position of the buffer plate 6 with respect to the limiting plate 47.

[0027] Two adjusting plates 7 are provided on the lower side of the rotating plate 2, and the two adjusting plates 7 are arranged parallel to each other. The periphery of the cantilever 41 is located between the two adjusting plates 7. Adjusting bolts 72 are threaded to both sides of one end of the cantilever 41. Each adjusting plate 7 is provided with an elongated hole 71. The periphery of the adjusting bolt 72 can slide in the elongated hole 71. The adjusting bolt 72 is used to fix the relative position between the cantilever 41 and the rotating plate 2. The height of the cantilever 41 relative to the angle steel material can be adjusted by adjusting the adjusting bolt 72 on the adjusting plate 7 so as to adapt to angle steel materials of different specifications.

[0028] The punching equipment is located between the material conveying device and the unloading conveying device. The unloading conveying device is existing technology. A baffle plate 8 is installed on the material support 5 away from the punching equipment. The baffle plate 8 does not interfere with the movement of the cantilever 41, and one end of the angle steel material can abut against one side of the baffle plate 8. When the angle steel material moves relative to the material support 5, the end of the angle steel material will abut against one side of the baffle plate 8. At this time, the angle steel material moves into place so that the clamp 42 and the clamping groove 43 on the cantilever 41 can clamp the end of the angle steel material.

[0029] The material support 5 has an L-shaped structure, and multiple sets of guide wheels are installed axially inside the L-shaped structure. Each set of guide wheels includes two guide rollers, which are arranged opposite to each other. The two guide rollers are rotatably connected to the inner walls of both sides of the L-shaped structure, and the outer periphery of the angle steel material is rolled to the outer periphery of each guide roller.
