Description

Technical Field

[0001] This application relates to the field of machining technology, specifically to a device for adjusting the tilt angle of a rebar bending machine head. Background Technology

[0002] A rebar bending machine is a piece of equipment specifically designed for efficient rebar processing, featuring a compact structure and powerful functionality. Structurally, it includes a frame, an automatic feeding drum or dial, and multiple independent bending heads (i.e., machine heads). Each bending head is responsible for a different bending task, thus achieving flexible and efficient rebar processing. However, in existing technologies, the bending heads of rebar bending machines are fixed vertically mounted on the frame, making it impossible to adjust the tilt angle during rebar bending. Furthermore, multiple bending heads on the same plane are prone to collisions, leading to deformation and damage to the bending structure. Utility Model Content

[0003] In view of the above problems, this application provides a rebar bending machine head tilt angle adjustment device to solve the technical problem that the bending head of the rebar bending machine cannot be adjusted at the angle and is prone to collision. To achieve the above objective, this application provides a rebar bending machine head tilt angle adjustment device, including: a base plate, a hinge plate, an angle adjustment plate, an inclined sliding groove, and an adjusting screw assembly;

[0004] The base plate is horizontally mounted on the frame of the rebar bending machine. The bending head of the rebar bending machine is mounted on the angle adjusting plate. One end of the angle adjusting plate is hinged to the hinge plate via a first hinge shaft, and the hinge plate is hinged to the base plate via a second hinge shaft. The other end of the angle adjusting plate is connected to the inclined sliding groove via the adjusting screw assembly. The inclined sliding groove is provided along the length direction of the base plate and is inclined along the thickness direction of the base plate.

[0005] The adjusting screw assembly includes an adjusting screw, a screw nut, and a screw sleeve. The screw nut is threadedly connected to the adjusting screw, and the screw nut is provided with a cross pin, which forms a T-shape with the screw nut. The cross pin is slidably disposed in the inclined sliding groove and hinged to the angle adjusting plate. The screw sleeve is rotatably sleeved on the outer circumference of the adjusting screw, and the adjusting screw is hinged to the base plate through the screw sleeve. When the adjusting screw rotates circumferentially, it drives the screw nut to move axially relative to the adjusting screw, causing the cross pin to drive the end of the angle adjusting plate to move along the inclined sliding groove, thereby adjusting the installation angle and spacing of the angle adjusting plate.

[0006] Furthermore, a first protrusion is provided at one end of the base plate, and a second protrusion is provided at the other end of the base plate. The first protrusion and the second protrusion protrude in the same direction along the thickness of the base plate; the angle adjustment plate is disposed between the first protrusion and the second protrusion.

[0007] The other end of the hinge plate is hinged to the first boss; the inclined sliding groove is provided on the side of the second boss near the angle adjustment plate.

[0008] Furthermore, a pin hole is provided on the side of the second boss away from the angle adjustment plate; a hinge block adapted to the pin hole is provided on the outside of the lead screw bushing, and is hinged to the second boss through the hinge block; the inclined sliding groove is provided on the side of the second boss near the angle adjustment plate.

[0009] Furthermore, the second boss is provided with two mutually symmetrical inclined sliding grooves along the width direction, and the two ends of the transverse pin are located in the corresponding inclined sliding grooves.

[0010] Furthermore, the end of the adjusting screw away from the cross pin is provided with an adjusting groove to accommodate an adjusting wrench; the surface of the angle adjusting plate is provided with a plurality of mounting holes for connecting with the bending head.

[0011] Furthermore, the length ratio of the angle adjustment plate to the hinge plate is 3:1 to 4:1.

[0012] Furthermore, the adjusting lead screw and the lead screw bushing are rotatably connected by a rotary bearing.

[0013] Furthermore, the angle adjustment plate is provided with clearance holes corresponding to the cross pin.

[0014] Unlike existing technologies, the above-mentioned head tilt angle adjustment device includes a base plate, a hinge plate, an angle adjustment plate, and a screw adjustment assembly. The two ends of the angle adjustment plate are respectively hinged to different positions of the base plate through the hinge plate and the screw adjustment assembly. The two ends of the angle adjustment plate are adjusted simultaneously, thereby allowing for more precise adjustment of the installation angle of the bending head. During angle adjustment, one end of the angle adjustment plate can slide along the inclined sliding groove, while the other end is driven to swing by the hinge plate, thus enabling precise adjustment of the installation angle of the bending head.

[0033] Please see Figures 1 to 4 This embodiment provides a head tilt angle adjustment device for a rebar bending machine. The head tilt angle adjustment device is installed on the frame of the rebar bending machine and is connected to the bending head of the rebar bending machine, used to adjust the installation angle of the bending head. The bending head is a key component of the rebar bending machine, used to apply a certain bending force to the rebar to bend it into a predetermined shape, such as an L-shape, rectangle, etc.

[0034] like Figure 1 As shown, in this embodiment, the head tilt angle adjustment device of the rebar bending machine includes: a base plate 1, an angle adjustment plate 2, a hinge plate 3, and a screw adjustment assembly 4.

[0035] The base plate 1 is used to fix the machine head tilt angle adjustment device on the frame.

[0036] Angle adjustment plate 2 is used to adjust the installation angle of the bending head. One end of angle adjustment plate 2 is hinged to one end of hinge plate 3, and the other end of hinge plate 3 is hinged to base plate 1. The other end of angle adjustment plate 2 is hinged to base plate 1 via screw adjustment assembly 4. Figure 2 and Figure 3 As shown, the end of the hinge plate 3 closest to the angle adjustment plate 2 is hinged to the angle adjustment plate 2 via a first hinge shaft 31; the end of the hinge plate 3 furthest from the angle adjustment plate 2 is hinged to the base plate 1 via a second hinge shaft 32. Therefore, the hinge plate 3 can swing around the second hinge shaft 32, and the angle adjustment plate 2 can swing around the first hinge shaft 31.

[0037] The lead screw adjustment assembly 4 includes a lead screw nut 40, an adjusting lead screw 43, and a lead screw bushing 42.

[0038] One end of the lead screw nut 40 is provided with a transverse pin 41, forming a T-shaped structure with the lead screw nut 40. The lead screw nut 40 is hinged to the other end of the angle adjusting plate 2 via the transverse pin 41, and both ends of the transverse pin 41 are disposed within the inclined sliding groove 13; the inclined sliding groove 13 is disposed on the base plate 1, and the inclined sliding groove 13 is inclined along the thickness direction of the base plate 1. Figure 2 and Figure 3 As shown, arrow X points in the length direction of base plate 1, arrow Y points in the width direction of base plate 1, and arrow Z points in the thickness direction of base plate 1. In this embodiment, the inclined sliding groove 13 is provided along the length direction of base plate 1 and is inclined along the thickness direction of base plate 1. The inclined sliding groove is provided on the side of the second boss near the angle adjustment plate. Furthermore, the second boss has two mutually symmetrical inclined sliding grooves along its width direction, and the two ends of the cross pin are located within the corresponding inclined sliding grooves.

[0039] The lead screw nut 40 is threadedly connected to the adjusting lead screw 43. The lead screw sleeve 42 is rotatably fitted around the outer circumference of the adjusting lead screw 43, and the adjusting lead screw 43 is hinged to the base plate 1 via the lead screw sleeve 42. For example, the lead screw sleeve 42 can be rotatably mounted on the outer circumference of the adjusting lead screw 43 via a rotary bearing. When the adjusting lead screw 43 rotates, the axial positions of the adjusting lead screw 43 and the lead screw sleeve 42 remain relatively fixed, while the axial positions of the adjusting lead screw 43 and the lead screw nut 40 change with rotation. Therefore, when the adjusting lead screw 43 rotates relative to the lead screw nut 40, the cross pin 41 and the other end of the angle adjusting plate 2 slide along the inclined sliding groove 13, thereby causing the hinge plate 3 to swing to adjust the angle of the angle adjusting plate 2. The length ratio of the angle adjustment plate 2 to the hinge plate 3 is 3:1 to 4:1, and the angle between the inclined sliding groove 13 and the base plate 1 is 25 degrees to 35 degrees.

[0040] In some embodiments, clearance holes 21 corresponding to the horizontal pin 41 are provided on both sides of the angle adjustment plate 2.

[0041] like Figure 2 and Figure 3 As shown, a first boss 11 is provided at one end of the base plate 1, and a second boss 12 is provided at the other end of the base plate 1. The first boss 11 and the second boss 12 protrude in the same direction along the thickness of the base plate 1. The angle adjustment plate 2 is disposed between the first boss 11 and the second boss 12. The first boss 11, the second boss 12 and the base plate 1 can be an integral structure.

[0042] like Figure 2 and Figure 3As shown, the other end of the hinge plate 3 is hinged to the first boss 11; the inclined sliding groove 13 is provided on the side of the second boss 12 near the angle adjusting plate 2. Furthermore, a pin hole 121 is provided on the side of the second boss 12 away from the angle adjusting plate 2; a hinge block adapted to the pin hole 121 is provided on the outside of the lead screw bushing 42, and it is hinged to the second boss 12 through the hinge block.

[0043] In the above embodiment, the base plate 1 is placed horizontally and fixed on the frame of the rebar bending machine. For ease of installation, multiple mounting holes for connecting to the bending head are provided on the surface of the angle adjusting plate 2. The right end of the base plate 1 is hinged to the hinge plate 3 via a second hinge shaft 32, and the hinge plate 3 is hinged to the angle adjusting plate 2 via a first hinge shaft 31. A lead screw nut 40 is installed at the front end of the angle adjusting plate 2. The adjusting lead screw 43 is threadedly connected to the lead screw nut 40, and the other end of the adjusting lead screw 43 passes through a cross pin 41. The outer side of the adjusting lead screw 43 is axially fixed to the base plate 1 by a lead screw bushing 42. To facilitate rotation of the adjusting lead screw 43, an adjusting groove is provided at the end of the adjusting lead screw 43 to accommodate an adjusting wrench. The adjusting groove can be an internal hexagonal groove, a slotted groove, or a cross groove, etc. The base plate 1 is provided with a sloping sliding groove 13, and both ends of the lead screw nut 40 can slide along the sliding groove.

[0044] When adjusting the bending head angle, use an Allen wrench or similar tool to rotate the adjusting screw 43 in the preset direction (e.g., clockwise). Through the threaded connection between the adjusting screw 43 and the screw shaft nut 40, both ends of the screw shaft nut 40 slide down along the inclined sliding groove 13 of the machine head adjusting base plate 1. Therefore, under the action of the hinge plate 3, the upper surface of the angle adjusting plate 2 tilts forward, and the machine head angle installed on the angle adjusting plate 2 tilts forward. Conversely, it tilts backward, thereby realizing the adjustment of the machine head tilt angle.

[0045] In this embodiment, the overall tilt angle of the bending head (i.e., the machine head) is adjustable, so that the bending heads of the steel bars are not on the same plane after bending, thus preventing the last two bending heads of the steel bars from colliding and causing the stirrups to deform.

[0046] In this embodiment, the bending head's tilt angle adjustment is highly efficient, the adjustment process is smooth, and the angle adjustment is convenient. Specifically, in this embodiment, both ends of the angle adjustment plate 2 are adjusted simultaneously, allowing for more precise adjustment of the bending head's installation angle. Furthermore, the distance between the angle adjustment plate 2 and the base plate 1 is adjusted accordingly during adjustment. Therefore, this technical solution not only allows for precise adjustment of the bending head's installation angle but also adjusts its installation distance on the frame, enabling multi-dimensional spatial adjustment of the bending head.

[0047] like Figure 3As shown, in one embodiment, the height of the first boss 11 is less than the height of the second boss 12, and the surface of the angle adjusting plate 2 away from the base plate 1 is an inclined surface, such that the thickness of the end of the angle adjusting plate 2 near the first boss 11 is less than the thickness of the other end near the second boss 12. In another embodiment, a rebar bending machine is disclosed. The rebar bending machine includes a frame and a plurality of bending heads; the bending heads are used to bend rebars;

[0048] Each of the bending heads is mounted on the frame via an angle adjustment device, which is the head tilt angle adjustment device of the rebar bending machine described in any of the above embodiments.

[0049] like Figure 4 The diagram shows the closed state of the head tilt angle adjustment device of the rebar bending machine. It can be seen that in this embodiment, the angle adjustment plate 2 can be completely fitted onto the base plate 1, and the angle adjustment plate 2 has a large angle adjustment range, fast adjustment speed, and stable structure.

[0050] Finally, it should be noted that although the above embodiments have been described in the text and drawings of this application, this should not limit the scope of patent protection of this application. Any technical solutions that are based on the essential concept of this application and utilize the content described in the text and drawings of this application, resulting in equivalent structural or procedural substitutions or modifications, as well as the direct or indirect application of the technical solutions of the above embodiments to other related technical fields, are all included within the scope of patent protection of this application.
