Description

Technical Field

[0001] This application relates to the field of bar processing, and particularly to a bar cutting device. Background Art

[0002] Bars generally refer to a kind of material product with a cross-sectional shape of simple figures such as circular, square, hexagonal, octagonal, etc., a relatively large length compared to the cross-sectional dimensions, and usually provided in a straight bar shape. Before the bars are used, they usually need to be cut into multiple segments. Currently, the cutting of bars is usually completed by a cutting machine. However, for existing cutting machines, they cannot effectively limit the position of the bars during cutting, resulting in the bars being prone to deviation during cutting, which greatly reduces the cutting quality of the bars. Summary of the Utility Model

[0003] In order to overcome the deficiencies of the prior art, this application provides a bar cutting device that can effectively limit the position of the bars.

[0004] The bar cutting device provided by this application adopts the following technical solutions:

[0005] A bar cutting device includes a machine base, a cutting machine provided on the machine base, and a limiting component also provided on the machine base. The limiting component includes two limiting seats arranged at intervals, and there is a cutting gap between the two limiting seats. Both ends of the bar are respectively placed in the two limiting seats, and the part of the bar to be cut is exposed in the cutting gap.

[0006] By adopting the above technical solutions, the bar can be effectively limited through the cooperation of the two limiting seats, avoiding the deviation of the bar during cutting and improving the cutting quality of the bar; at the same time, the cutting machine can accurately cut the part of the bar to be cut through the cutting gap, greatly improving the cutting accuracy of the bar.

[0007] In a specific feasible implementation, each of the limiting seats is respectively provided with a limiting groove for accommodating the bar, and the extending directions of the two limiting grooves are the same.

[0008] By adopting the above technical solutions, the two limiting grooves can respectively accommodate the two ends of the bar to effectively limit the bar.

[0009] In a specific feasible implementation, the radial cross-section of the limiting groove is polygonal.

[0010] By adopting the above technical solutions, the relative rotation between the bar and the limiting groove can be effectively reduced.

[0011] In a specific feasible implementation, the groove wall of the limiting groove is provided with lines.

[0012] By adopting the above technical solution, the texture can increase the friction between the limiting groove and the rod, and further reduce the relative rotation between the rod and the limiting groove.

[0013] In a specific possible implementation scheme, the limiting seat includes two seat bodies arranged side by side, and the two seat bodies are respectively provided with groove bodies on one side close to each other, and the two groove bodies enclose the limiting groove.

[0014] By adopting the above technical solution, the difficulty of assembling the rod in the limiting groove is effectively reduced; at the same time, the processing difficulty of the split limiting seat is lower.

[0015] In a specific possible implementation manner, at least one of the two bases is movably arranged along a direction approaching or moving away from the other one, and the limiting assembly further includes a first driving module for driving the base to move.

[0016] By adopting the above technical solution, the limit groove can flexibly adjust its own groove diameter during the movement of the seat body to adapt to rods of various specifications, with a wider range of applications; at the same time, the movable seat body can press the rod against another seat body during its movement, further enhancing the limiting effect of the limit seat on the rod.

[0017] In a specific feasible implementation scheme, the two limit seats are respectively a first limit seat and a second limit seat, a first limit slot is provided in the first limit seat, a second limit slot is provided in the second limit seat, a stop rod is inserted into the end of the first limit slot away from the second limit seat, the stop rod is slidably arranged along the extension direction of the first limit slot, and the limit assembly also includes a second driving module for driving the stop rod to slide.

[0018] By adopting the above technical solution, the baffle rod can support one end of the rod to prevent the rod from axial movement during cutting, thereby further improving the cutting quality of the rod; at the same time, the baffle rod can also adjust the extension length of the rod in the first limiting groove to adjust the position of the rod, so that the part of the rod to be cut can be accurately exposed to the cutting gap, thereby further improving the cutting accuracy of the rod.

[0019] In a specific possible implementation manner, the limiting seat has a relief portion at one end close to the cutting gap, and the relief portion is tapered.

[0020] By adopting the above technical solution, not only can the interference of the limiting seat with the cutting of the cutting machine be avoided, but the conical clearance portion can also provide clearance space for the debris after cutting, thereby avoiding the accumulation of debris and affecting the use of the limiting seat.

[0021] In a specific possible implementation manner, a chip carrying tray is further provided in the cutting gap.

[0022] By adopting the above technical solution, the debris after cutting can be effectively prevented from scattering.

[0023] In summary, the present application includes at least one of the following beneficial technical effects:

[0024] 1. The bar can be effectively limited by the cooperation of two limit seats, avoiding the deviation of the bar during cutting and improving the cutting quality of the bar;

[0025] 2. The cutting machine can accurately cut the part of the bar to be cut through the cutting gap, which greatly improves the cutting accuracy of the bar. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0029] The present application is further described in detail below in conjunction with the accompanying drawings.

[0030] See also Figure 1 As shown, a rod cutting device is shown, including a machine base 1, on which a cutting machine 2 and a limiting assembly 3 are arranged. The limiting assembly 3 includes two limiting seats 31 spaced apart along the length direction of the machine base 1, and a cutting gap 32 is provided between the two limiting seats 31. The two ends of the rod are respectively accommodated in the two limiting seats 31 and the part of the rod to be cut is exposed in the cutting gap 32. The cutting machine 2 is arranged on one side of the cutting gap 32, and the cutting disk of the cutting machine 2 is located directly above the cutting gap 32 and can cut the part of the rod to be cut. Among them, the cutting machine 2 is a prior art, and its specific structure and cutting principle are not repeated.

[0031] During cutting, the rod can be effectively limited by the cooperation of the two limit seats 31, avoiding the displacement of the rod during cutting and improving the cutting quality of the rod; at the same time, the cutting machine 2 can accurately cut the part to be cut of the rod through the cutting gap 32, greatly improving the cutting accuracy of the rod.

[0032] In this embodiment, a limiting groove 33 for accommodating the bar is respectively formed in each limiting seat 31, and both limiting grooves 33 extend along the length direction of the machine base 1.

[0033] Among them, the radial cross-section of the limiting groove 33 is quadrilateral, and a texture 34 is further provided on the groove wall of the limiting groove 33, and the texture 34 extends along the length direction of the limiting groove 33. The limiting groove 33 with a quadrilateral radial cross-section can effectively reduce the relative rotation between the bar and the limiting groove 33; and the texture 34 can increase the friction between the limiting groove 33 and the bar, further reducing the relative rotation between the bar and the limiting groove 33.

[0034] In this embodiment, the limiting seat 31 includes two seat bodies 311 arranged side by side along the width direction of the machine base 1. Groove bodies 331 are respectively formed on one side of the two seat bodies 311 close to each other, and the two groove bodies 331 enclose the limiting groove 33. The split-type limiting seat 31 not only effectively reduces the assembly difficulty of the bar in the limiting groove 33, but also reduces the processing difficulty of the limiting seat 31 itself.

[0035] Furthermore, one of the two seat bodies 311 is movably arranged along the width direction of the machine base 1. The limiting component 3 further includes a first driving module 35 for driving the movement of the seat body 311. The first driving module 35 is a ball screw structure, and a handwheel is connected to the screw.

[0036] When facing bars of different specifications, the worker can rotate the handwheel to make the two seat bodies 311 approach or move away from each other, so as to reduce or expand the groove diameter of the limiting groove 33, so that the limiting groove 33 can adapt to bars of various specifications, and the application range is wider; at the same time, the movable seat body 311 can press the bar against the other seat body 311 during its movement, further improving the limiting effect of the limiting seat 31 on the bar.

[0037] In this embodiment, the two limiting seats 31 are respectively a first limiting seat 31a and a second limiting seat 31b. There are two limiting grooves 33, which include a first limiting groove 33a formed in the first limiting seat 31a and a second limiting groove 33b formed in the second limiting seat 31b. A stop bar 36 is inserted at one end of the first limiting groove 33a far from the second limiting seat 31b, and the stop bar 36 is slidably arranged along the extending direction of the first limiting groove 33a. The limiting component 3 further includes a second driving module 37 for driving the sliding of the stop bar 36.

[0038] During cutting, the bar is inserted into the second limiting groove 33b from the notch at the end far away from the first limiting seat 31a. The bar passes through the second limiting groove 33b and the first limiting groove 33a in sequence and then abuts against the stop bar 36. The stop bar 36 can resist one end of the bar, avoiding axial movement of the bar during cutting, and further improving the cutting quality of the bar. At the same time, by moving the stop bar 36, the insertion length of the bar in the first limiting groove 33a can be adjusted to adjust the position of the bar, so that the part to be cut of the bar can be accurately exposed in the cutting gap 32, further improving the cutting accuracy of the bar.

[0039] In this embodiment, one end of the limiting seat 31 close to the cutting gap 32 respectively has a relief portion 38, and the relief portion 38 is conical. The conical relief portion 38 can not only prevent the limiting seat 31 from interfering with the cutting of the cutting machine 2, but also provide a relief space for the cut debris, avoiding the accumulation of debris and affecting the use of the limiting seat 31.

[0040] A chip-loading tray 39 is also arranged in the cutting gap 32. The chip-loading tray 39 can effectively prevent the cut debris from scattering and falling.

[0041] The implementation principle of a bar cutting device according to an embodiment of the present application is as follows:

[0042] Insert the bar into the second limiting groove 33b from the notch at the end far away from the first limiting seat 31a. The bar passes through the second limiting groove 33b and the first limiting groove 33a in sequence and then abuts against the stop bar 36;

[0043] The second driving module 37 drives the stop bar 36 to slide. The stop bar 36 pushes the bar to move and adjusts the position of the bar, so that the part to be cut of the bar is accurately exposed in the cutting gap 32;

[0044] The first driving module 35 drives the seat body 311 to move and clamp the bar. Then, the cutting machine 2 cuts the bar. After cutting is completed, the bar can be taken out.

[0045] The above are all the preferred embodiments of the present application. The protection scope of the present application is not limited accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application should be covered within the protection scope of the present application.
