Description

Technical Field

[0001] The utility model relates to the technical field of steel bar cutting machines, and particularly refers to a material retaining mechanism of a steel bar cutting machine. Background Art

[0002] A steel bar cutting machine is a common processing device. Through the cooperation of a material retaining mechanism and a cutting tool, steel bars with required lengths can be quickly and accurately cut. By moving the position of the material retaining mechanism, it is convenient to determine the length of the cut steel bars. The material retaining mechanisms of current steel bar cutting machines generally have several designed gears fixed. When the material retaining mechanism is in different gears, it can cooperate with the steel bar cutting machine to produce steel bars with different lengths. However, the steel bar cutting machine with fixed gears is not flexible enough in use and cannot meet the needs of various products.

[0003] For some current solutions that use a lead screw to adjust the position of the material retaining mechanism, during the actual working process, since the material retaining mechanism needs to constantly abut against one end of the steel bar to be cut and also apply a sufficient large force to fix the steel bar, the generated reaction force will be applied to the thread of the lead screw. After long-term work, the thread will be deformed and the lead screw cannot be rotated. That is, the purpose of adjusting the position of the material retaining mechanism cannot be achieved, and it is also difficult to take out the damaged lead screw, affecting subsequent use. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a material retaining mechanism of a steel bar cutting machine to improve the problem that the current material retaining mechanism is prone to deformation of the adjusting component under the long-term abutment of the steel bar.

[0005] The purpose of the utility model is achieved as follows:

[0007] A mounting seat, which is used to be mounted on a frame and has a mounting hole opened inside;

[0008] A material retaining member, whose rear end is an insertion end and the front end is a material retaining end. The insertion end is inserted into the mounting hole, and the material retaining end is placed outside;

[0009] A fixing component, which is mounted on the mounting seat and is used to fix the material retaining member in the mounting hole;

[0010] An adjusting component, which is mounted at the rear end of the fixing component and is used to adjust the length of the material retaining end extending out of the mounting hole;

[0011] Among them, the adjusting component includes:

[0012] An adjusting rod, whose front end is a connecting end. The connecting end is connected to the insertion end, and the adjusting rod is threadedly connected to the rear end part of the mounting hole.

[0013] Preferably, a ring groove is formed on the connecting end, so that the edge of the connecting end is a convex ring portion;

[0014] A T-shaped groove is formed on the insertion end, and the convex ring portion can slide into the T-shaped groove.

[0015] Preferably, a hook is arranged on the connecting end of the adjusting rod, and a hanging ring is rotatably arranged on the insertion end of the material blocking member;

[0016] When the hook is engaged with the hanging ring, the material blocking member and the adjusting rod are connected into one body.

[0017] Preferably, a tightening hole is further formed in the mounting seat, the tightening hole is perpendicular to the mounting hole and partially communicated;

[0018] A tightening groove is formed on the side wall of the tightening member of the fixing assembly, and the material blocking member is inserted through the cooperation of the tightening groove and the tightening hole;

[0019] By moving the tightening member, the side wall of the tightening groove presses against the material blocking member to realize the tightening and fixing of the material blocking member.

[0020] Preferably, a threaded portion is further formed on the tightening member;

[0021] When the tightening member is screwed into the tightening hole, by rotating the tightening member, the tightening groove can be abutted against the side wall of the material blocking member and the movement of the material blocking member in the mounting hole can be restricted;

[0022] Or the threaded portion is placed outside the tightening hole and a nut is screwed, and by rotating the nut to pull the tightening member, the side wall of the tightening groove presses against the material blocking member to realize the tightening and fixing of the material blocking member.

[0023] Preferably, a material blocking surface is formed on the material blocking end, the upper end of the material blocking surface is a vertical plane, and the lower end of the material blocking surface is formed as a blanking inclined surface.

[0024] Preferably, a rotation limiting groove is formed on the side wall of the material blocking member, a rotation limiting hole is formed in the fixing assembly, and the rotation limiting hole is communicated with the mounting hole;

[0025] A rotation limiting pin is used to pass through the rotation limiting hole;

[0026] When the material blocking member is inserted into the mounting hole, one end of the rotation limiting pin can pass through the rotation limiting hole and be placed in the rotation limiting groove.

[0027] Preferably, a connecting base is formed at the lower end of the fixing assembly, a support rod is vertically screwed on the connecting base, and the lower end of the support rod abuts against the frame to support the mounting seat.

[0030] 1. The adjusting rod and the material blocking member in the present technical solution are not integrally formed, and an additional clamping force is applied to the material blocking member alone to limit the movement of the material blocking member. Therefore, when the steel bar abuts against the material blocking surface of the material blocking member, the pressure generated by part of the steel bar will be dispersed, so as to reduce the axial pressure directly applied to the adjusting rod, and thus reduce the deformation of the thread of the adjusting rod.

[0031] 2. In the present technical solution, a clamping member is provided, and the clamping member can generate an additional frictional force on the material blocking member by abutting against the circumferential side of the material blocking member, further reducing the movement of the material blocking member, thereby reducing the material blocking member from pushing the adjusting rod, and achieving the purpose of reducing the excessive axial pressure on the adjusting rod.

[0032] 3. A blanking inclined surface is formed on the lower end surface of the material blocking surface of the material blocking member in the present technical solution, which can facilitate the falling off of the steel bar when the steel bar is cut, and reduce the pressure applied by the steel bar on the material blocking member, so as to reduce the axial pressure on the adjusting rod.

[0033] 4. The material blocking assembly in the present technical solution can be assembled independently, thereby reducing the cost of transformation and upgrading of existing equipment. Description of the Drawings

[0048] The following are specific embodiments of the present utility model, and the technical solutions of the present utility model will be further described in conjunction with the drawings, but the present utility model is not limited to these embodiments.

[0049]

Embodiment 1

[0050] As Figures 1 - 3 shown, a material blocking mechanism of a steel bar cutting machine includes:

[0051] A mounting base 11, which is used to be mounted on a frame and has a mounting hole 13 opened inside.

[0052] A material blocking part 2, the rear end of which is an insertion end 21 and the front end is a material blocking end 22. The insertion end 21 is inserted into the mounting hole 13, and the material blocking end 22 is placed outside. The material blocking end 22 is used to abut against one end of the steel bar, so as to fix the position of the steel bar.

[0053] A fixed component 1, which is mounted on the mounting base 11 and is used to fix the material blocking part 2 in the mounting hole 13, so as to limit the continuous movement of the steel bar 6, and achieve the purpose of fixing the cutting length of the steel bar 6.

[0054] An adjusting component 28, which is mounted at the rear end of the fixed component 1 and is used to adjust the length of the material blocking end 22 extending out of the mounting hole 13.

[0055] Through the adjusting component 28, the material blocking part 2 can be driven to move, and the position of the material blocking part 2 can be adjusted, so that the cutting length of the steel bar 6 can be adjusted.

[0056] Among them, the adjusting component 28 includes:

[0057] The adjusting rod 3 has a connecting end 31 at its front end. The connecting end 31 is connected to the insertion end 21, and an external thread 32 is formed on the circumferential side of the adjusting rod 3. A threaded hole 14 is also formed at the rear end of the mounting seat 11. The threaded hole 14 communicates with the mounting hole 13 and the threaded hole 14 and the mounting hole 13 are located on the same axis. The adjusting rod 3 is threadedly connected into the threaded hole 14.

[0058] During the actual use process, when the steel bar 6 abuts against the material baffle 2, the steel bar 6 will also exert a large amount of force on the material baffle 2, thereby preventing the steel bar 6 from falling off. And this part of the force will often be transmitted to the adjusting rod 3 of the adjusting assembly 28. Since the adjusting rod 3 is threadedly connected to the mounting seat 11, when the force on the adjusting rod 3 is too large, it is very easy to cause the external thread 32 to bend, resulting in difficulty for the adjusting rod 3 to rotate normally, and further making it very difficult to move the position of the adjusting rod 3 and remove the adjusting rod 3. This also makes the service life of the material baffle mechanism on many steel bar cutters relatively short.

[0059] In this technical solution, by separately manufacturing the material baffle 2 and the adjusting rod 3, and then connecting the material baffle 2 and the adjusting rod 3 together and passing them through the mounting seat 11, when the material baffle 2 is subjected to the pressure of the steel bar 6, the force received will not be preferentially transmitted to the adjusting rod 3, thereby reducing the external force on the external thread 32 of the adjusting rod 3, avoiding bending deformation of the external thread 32, and achieving the purpose of extending the service life of the adjusting rod 3.

[0060] Specifically as Figure 2 shown, in this embodiment, a ring groove 33 is formed on the connecting end 31, so that the edge of the connecting end 31 is a convex ring portion 36.

[0061] A T-shaped groove 23 is formed on the insertion end 21. The convex ring portion 36 can slide into the T-shaped groove 23 along the length direction of the T-shaped groove 23, and the convex ring portion 36 cannot be axially separated from the T-shaped groove 23. Thus, the convex ring portion 36 can be embedded into the T-shaped groove 23, connecting the connecting end 31 of the adjusting rod 3 and the insertion end 21 of the material baffle 2 together.

[0062] Rotating the adjusting rod 3 can drive the adjusting rod 3 to move within the mounting seat 11. Since the convex ring portion 36 cannot be axially separated from the T-shaped groove 23, when the convex ring portion 36 abuts against the inner side of the T-shaped groove 23, it can drive the material baffle 2 to move along the axial direction of the adjusting rod 3.

[0063] As Figures 1 - 5 shown, a clamping hole 41 is also formed on the mounting seat 11. The clamping hole 41 is perpendicular to the mounting hole 13 and is partially connected.

[0064] A clamping groove 43 is formed on the side wall of the clamping member 4 of the fixing assembly 1. The clamping groove 43 and the clamping hole 41 cooperate to realize the insertion of the material baffle 2.

[0065] By moving the clamping member 4, the side wall of the clamping groove 43 is pressed against the side wall of the material retaining member 2. As the clamping member 4 is further tightened, the pressure between the clamping groove 43 and the material retaining member 2 can be further increased, thereby increasing the frictional force generated between the clamping groove 43 and the material retaining member 2. When the steel bar 6 abuts against the material retaining member 2, the frictional force generated between the clamping groove 43 and the material retaining member 2 will first offset the pressure exerted by the steel bar 6 on the material retaining member 2. While restricting the movement of the material retaining member 2, it can also correspondingly reduce the pressure transmitted from the material retaining member 2 to the adjusting rod 3, thereby reducing the pressure on the external thread 32 of the adjusting rod 3 and avoiding deformation of the external thread 32.

[0066] Furthermore, a threaded portion 42 is formed on the clamping member 4.

[0067] When the clamping member 4 is screwed into the clamping hole 41, by rotating the clamping member 4, the clamping groove 43 can be made to abut against the side wall of the material retaining member 2 and restrict the movement of the material retaining member 2 within the mounting hole 13.

[0068] Or the threaded portion 42 is placed outside the clamping hole 41 and a nut is screwed thereon. By rotating the nut to pull the clamping member 4, the side wall of the clamping groove 43 is pressed against the material retaining member 2, realizing the clamping and fixing of the material retaining member 2.

[0069] As Figure 3 shown, a material retaining end 22 is formed with a material retaining surface. The upper end of the material retaining surface is a vertical plane 26, and the lower end of the material retaining surface is formed as a blanking inclined surface 27.

[0070] When the steel bar cutting machine cuts the steel bar 6, the steel bar 6 will protrude from the claw disc, and after the end of the steel bar 6 abuts against the material retaining member 2, the steel bar 6 is cut, so as to limit the length of the steel bar 6 protruding from the claw disc and obtain the steel bar 6 of the required length.

[0071] When cutting the steel bar 6, since the end of the steel bar 6 abuts against the material retaining end 22 of the material retaining member 2, and when cutting the steel bar 6, the cutter applies a force to the cutting part of the steel bar 6, resulting in the inclined state of the cut steel bar 6. The flat material retaining surface will prevent the steel bar 6 from falling.

[0072] Specifically as Figure 6 shown, therefore, the upper side of the material retaining surface is formed as a vertical plane 26 for abutting against the end of the steel bar, and the lower side of the material retaining surface is formed as an inclined blanking inclined surface 27. When the steel bar 6 is cut and inclined, the blanking inclined surface 27 can provide enough space for the steel bar 6 to fall.

[0073] As Figures 2 - 4 shown, a rotation limiting groove 25 is formed on the side wall of the material retaining member 2, and a rotation limiting hole 51 is formed on the fixing assembly 1. The rotation limiting hole 51 is communicated with the mounting hole 13.

[0074] The limited rotation hole 51 is for passing through the limited rotation pin 5.

[0075] When the material blocking member 2 is passed through the mounting hole 13, one end of the limited rotation pin 5 can pass through the limited rotation hole 51 and be placed into the limited rotation groove 25.

[0076] Since the material blocking member 2 is only passed through the mounting hole 13, the material blocking member 2 is likely to rotate, thus affecting the positions of the vertical plane 26 and the blanking inclined plane 27. By providing the limited rotation pin 5, the orientation of the material blocking member 2 can be fixed to prevent the material blocking member 2 from rotating.

[0077] As Figure 1 、 Figure 3 and Figure 7 As shown, a connecting base 15 is formed at the lower end of the fixing assembly 1, and a support rod is vertically screwed onto the connecting base 15. The lower end of the support rod is used to abut against the machine frame. The support rod is used to support the mounting seat 11, thereby mounting the mounting seat 11 onto the machine frame.

[0078] As Figures 1 - 3 shown, the adjusting assembly 28 further includes a threaded compression sleeve 12. The threaded compression sleeve 12 is fixed at the rear end of the mounting seat 11, and the adjusting rod 3 is screwed into the threaded compression sleeve 12. When the adjusting rod 3 is rotated, the adjusting rod 3 can be moved within the threaded compression sleeve 12, thereby achieving the purpose of moving the adjusting rod 3.

[0079] An adjusting nut 35 is also sleeved on the adjusting rod 3. The adjusting nut 35 can further assist in confirming the length of the adjusting rod 3 extending into the threaded compression sleeve 12, so as to facilitate the operator's adjustment. At the same time, when the adjusting nut 35 can abut against the threaded compression sleeve 12, the position of the adjusting rod 3 can be further fixed to prevent the adjusting rod 3 from moving.

[0080]

[0083] When the hook 34 cooperates with the hanging ring 24, the material blocking member 2 and the adjusting rod 3 are connected into one body.
