Description

Technical Field

[0001] This utility model relates to the field of metal bar cutting technology, and in particular to a metal bar feeding and cutting device. Background Technology

[0002] Metal bar feeding and cutting device is an automated / semi-automated mechanical equipment. Its core function is to realize the integrated operation of "automatic feeding" and "precision cutting" of metal bars (such as round steel, square steel, copper tube, aluminum rod, etc.). It is widely used in machinery manufacturing, automotive parts, hardware processing, home appliance parts and other fields.

[0003] The attached diagram of the instruction manual Figure 1 The demonstration showed that in current metal bar shearing machines, the clamping mechanism drives the fixture to deflect around a fixed axis to hold the metal bar, and the hydraulic system moves the fixture and the metal bar to achieve precise cutting. However, when cutting metal bars with a large diameter, the fixture will contact the outer circumference of the metal bar before deflecting to a vertical position. This results in a vertically downward component of the clamping force on the metal bar, which is not conducive to stable clamping of the metal bar.

[0004] Therefore, it is necessary to provide a metal bar feeding and cutting device to solve the above-mentioned technical problems. Utility Model Content

[0005] The purpose of this utility model is to provide a metal bar feeding and cutting device to solve the problem mentioned in the background art that in the existing metal bar shearing machine, when cutting metal bars with a large diameter, the clamps on both sides of the metal bar will clamp the metal bar in an inclined state, so that the clamping force of the clamp on the metal bar has a vertical component, which is not conducive to the stable clamping of the metal bar.

[0006] Based on the above ideas, this utility model provides the following technical solution: a metal bar feeding and cutting device, including a clamping assembly for clamping the metal bar, a pushing unit for moving the clamping assembly, and a cutting assembly for cutting the metal bar. The clamping assembly includes a clamping plate housed in a housing and rotatably engaged with the housing. The portion of the clamping plate near the top is configured as an outwardly inclined guide portion. Rollers are attached to both the inner and outer surfaces of the guide portion. The movement of the rollers relative to the guide portion in the vertical direction can drive the clamping plate to deflect relative to the housing. A clamping member is provided on the inner side of the clamping plate, and the clamping member is elastically connected to the clamping plate. When the clamping plate is deflected to a vertical state relative to the housing, the clamping member can lock with the clamping plate.

[0007] As a further embodiment of this utility model: the clamping member is provided with a sliding rod, the sliding rod passes through the clamping plate, a sliding member is slidably assembled on the outer side of the clamping plate, the sliding rod passes through a pre-set slot on the sliding member, and a limiting member is provided at the top of the slot, and multiple sets of limiting holes that cooperate with the limiting member are evenly arranged on the outer circumference of the sliding rod along the axial direction of the sliding rod.

[0008] As a further embodiment of this utility model: a gear shaft is rotatably provided inside the housing along its width direction, the surface of the sliding member is provided with transmission teeth that mesh with the gear shaft, and an arc-shaped rack that meshes with the gear shaft is fixedly provided on the inner wall of the housing. During the process of the clamping plate deflecting relative to the housing, the gear shaft can mesh with the rack.

[0009] As a further embodiment of this utility model: a mounting bracket is slidably assembled in the strip groove opened at the guide part, the roller is mounted on the mounting bracket, and the two mounting brackets are connected by a crossbeam so as to drive the two clamping plates to deflect synchronously.

[0010] As a further embodiment of this utility model: a pin is fixedly provided on the side of the clamping plate, and the pin passes through the housing and is rotatably connected to the housing.

[0011] As a further embodiment of this utility model: one end of the slide rod passing through the slot extends outward along the diameter direction of the slide rod to form a flange to prevent the slide rod from separating from the clamping plate.

[0012] As a further embodiment of this utility model: the center of the rack is located on the axis of the pin.

[0013] As a further embodiment of this utility model, the rack is positioned between the clamping plate and the inner wall of the housing to avoid interference between the clamping plate and the rack when the clamping plate deflects.

[0014] Compared with the prior art, the beneficial effects of this utility model are: when the clamping plate is deflected to a vertical state relative to the housing, the clamping member can lock with the clamping plate, so that the clamping member can apply a stable clamping force to the metal bar in the horizontal direction. In this solution, the stability of the clamping member in clamping the metal bar is not affected by the size of the metal bar, thereby significantly improving the applicability of the clamping assembly.

[0018] like Figures 1-7 As shown, a metal bar feeding and cutting device includes a clamping assembly 100 for clamping the metal bar, a pushing unit 200 for moving the clamping assembly 100, and a cutting assembly 300 for cutting the metal bar.

[0019] Combination Figures 2-7 As shown, the clamping assembly 100 includes a clamping plate 106 housed within a housing 101. The housing 101 has a U-shaped structure, and the clamping plate 106 is rotatable relative to the housing 101. Figure 4 As can be seen, the part of the clamping plate 106 near the top is set as an outwardly inclined guide portion 1061, and the "I"-shaped mounting bracket passes through the strip groove at the guide portion 1061 and slides in cooperation with the guide portion 1061. The end of the mounting bracket is rotatably mounted with a roller 109 via a bearing. It should be noted that the roller 109 rolls and adheres to the surface of the guide portion 1061. With this structure, when the roller 109 moves upward relative to the housing 101, the pressure of the roller 109 on the guide portion 1061 can drive the clamping plate 106 to deflect outward relative to the housing 101 to loosen the clamped metal bar. Conversely, the clamping plate 106 can clamp the metal bar tightly.

[0020] Furthermore, a pin 108 is fixedly installed on the side of the clamping plate 106, and the pin 108 passes through the housing 101 and is rotatably connected to the housing 101. The two mounting brackets are fixedly connected by a crossbeam 1010. A drive unit is installed on the top of the housing 101 to drive the crossbeam 1010 to move vertically relative to the housing 101. In summary, when the drive unit drives the crossbeam 1010 and the mounting bracket at the end of the crossbeam 1010 to move downward, the pressure of the roller 109 on the guide part 1061 can drive the clamping plate 106 to deflect inward relative to the housing 101 around the pin 108 to clamp the metal bar. Then, the pushing unit 200 pushes the metal bar forward. After it moves into position, the cutting assembly 300 cuts the metal bar. It should be noted that in order to maintain the stability of the clamping plate 106 in clamping the metal bar, the clamping plate 106 should be kept vertical to ensure that the clamping plate 106 can form a stable clamping force relative to the metal bar in the horizontal direction. Based on this, a plate-shaped clamping member 107 is provided on the inner side of the clamping plate 106, and the clamping member 107 is elastically connected to the clamping plate 106. When the clamping plate 106 is deflected to a vertical state relative to the housing 101, the clamping member 107 can lock with the clamping plate 106, so that the clamping member 107 can apply a stable clamping force to the metal bar in the horizontal direction. In this solution, the stability of the clamping member 107 in clamping the metal bar is not affected by the size of the metal bar, thereby significantly improving the applicability of the clamping assembly 100.

[0021] Combination Figures 4-7 As shown, a slide rod 105 is fixedly mounted on the clamping member 107. The slide rod 105 passes through the clamping plate 106 and slides with it. A sliding member 104 is slidably mounted on the outer side of the clamping plate 106. The slide rod 105 passes through a pre-set slot 1042 on the sliding member 104. Figures 5-7 As can be seen, a rod-shaped limiting member 1043 is provided at the top of the slot 1042. It should be noted that the limiting member 1043 can elastically engage with the sliding member 104 via a spring or similar structure. Furthermore, multiple sets of limiting holes 1051 are evenly arranged along the axis of the sliding rod 105 on its outer circumference. When the sliding member 104 moves downwards, causing the limiting member 1043 to insert into the limiting hole 1051, the clamping member 107 locks itself in place with the clamping plate 106. Figures 4-5As can be seen, a gear shaft 103 is rotatably arranged inside the housing 101 along its width direction, and the surface of the sliding member 104 is provided with transmission teeth 1041 that mesh with the gear shaft 103. In addition, an arc-shaped rack 102 that meshes with the gear shaft 103 is fixedly arranged on the inner wall of the housing 101. It should be noted that the center of the rack 102 is located on the axis of the pin 108, and the rack 102 is located between the clamping plate 106 and the inner wall of the housing 101 to avoid interference between the clamping plate 106 and the rack 102 when it deflects. In summary, in this embodiment, when the drive unit moves the crossbeam 1010 and the mounting bracket downwards, the clamping plate 106 can deflect inwards. When the clamping member 107 contacts the metal bar and the clamping plate 106 has not deflected to a vertical position, as the clamping plate 106 continues to deflect, the clamping member 107 can be compressed and move closer to the clamping plate 106. During this process, the meshing of the rack 102 and the gear shaft 103 can drive the gear shaft 103 to rotate, and then the meshing of the gear shaft 103 and the transmission gear 1041 can drive... When the sliding member 104 moves downward, and the clamping plate 106 and the clamping member 107 are deflected to the vertical position, the limiting member 1043 at the top of the slot 1042 will move to the slide rod 105 and press against the outer circumferential surface of the slide rod 105. When the limiting member 1043 is inserted into the limiting hole 1051, the clamping member 107 is locked with the clamping plate 106. At this time, the clamping member 107 can be pressed against one side of the metal bar by the cooperation of the roller 109 and the guide part 1061, thereby stably driving the metal bar to move forward.

[0022] Combination Figure 2 As shown, the pushing unit is a hydraulic rod. The metal rod is placed on the platform 400, and brackets are fixed on both sides of the top of the platform 400. The guide rod fixed between the two brackets passes through the housing 101 and slides with it. The pushing unit 200 is fixedly installed on the bracket.

[0023] The cutting assembly 300 includes a cutting unit 303. It should be noted that, in the embodiment of shearing metal bars, the cutting unit 303 can be a shearing slider, which is driven to move by an external hydraulic system to shear the metal bars. In the embodiment of sawing metal bars, the cutting unit 303 can be a circular saw. All related structures in the cutting assembly 300 are mounted on the base 304. The cutting assembly 300 can be selected from the prior art, and will not be described in detail in this embodiment.

[0024] Combination Figure 3 As shown, the metal bar is provided with a top pressing member 302 and a blocking member 301 on both sides. Both the top pressing member 302 and the blocking member 301 can be connected to an external hydraulic rod or cylinder. During the cutting process, the blocking member 301 and the top pressing member 302 are attached to the outside of the metal bar to fix the metal bar.

[0025] The aforementioned drive unit can be a hydraulic rod, the output end of which is fixedly connected to the crossbeam 1010, in conjunction with... Figure 4 As shown, one end of the slide rod 105 that passes through the slot 1042 extends outward along the diameter direction of the slide rod 105 to form a flange to prevent the slide rod 105 from separating from the clamping plate 106, and a limit spring is provided between the clamping member 107 and the clamping plate 106 to achieve elastic cooperation between the clamping member 107 and the clamping plate 106.

[0026] Combination Figure 5 As shown, the clamping plate 106 is provided with a through groove 1062, and a slide bar can be fixedly installed on the sliding member 104 so that the slide bar slides in the through groove 1062 to improve the stability of the sliding member 104 sliding up and down relative to the clamping plate 106.

[0027] The above-disclosed examples are merely preferred embodiments of this application, intended to facilitate understanding and implementation by those skilled in the art. However, they cannot be used to limit the scope of this application. Therefore, equivalent variations made within the scope of this application are still within the scope of this application.
