Referring to fig. 2 and 3, the worktable 100 includes two bumps 110, a groove 120 is formed between the two bumps 110, and an upper surface of each bump 110 is an inwardly concave curved surface.
When the sample 300 to be cut is placed on the worktable 100, two ends of the sample 300 to be cut are respectively placed on the two bumps 110, and end faces of the two ends of the sample 300 to be cut are respectively located in the middle of each bump 110.
Since the upper surface of the bump 110 is a curved surface that is depressed inward. As shown in fig. 1, the left end of the sample 300 to be cut is in contact with the upper end portion of the right side of the left bump 110, and the right end of the sample 300 to be cut is in contact with the upper end portion of the left side of the right bump 110.
When the sample 300 to be cut is in surface contact with the workbench 100, the workbench 100 can cause the sample 300 to be cut to be unstably placed due to the fact that the sample 300 to be cut is uneven such as chippings and residues, stress deviation is caused when the sample is cut, and the cutting effect can be seriously influenced. In the embodiment of the present application, the bump 110 is in line contact with the sample 300 to be cut, so that the sample 300 to be cut is more stably placed on the bump 110.
Meanwhile, after the sample 300 to be cut is cut into two pieces, the bottom end of the sample can be in quick contact with the bottom of the upper surface of the bump 110, so that the cut sample is bounced to both sides of the two bumps 110.
Optionally, the support portion of the bump 110 for supporting the sample 300 to be cut has a chamfer.
The tool bit 220 acts on the sample 300 to be cut and then applies huge impact force to the sample 300 to be cut instantly, the impact force is transmitted to the lug 110 supporting the sample, the supporting part of the lug 110 can generate reaction force with the same size and opposite direction, the reaction force acts on the lower end face of the sample 300 to be cut, and the too sharp supporting part can cut the lower end face of the sample 300 to be cut so that the sample 300 to be cut is cracked from the lower part.
The radian of the upper surface of the bump 110 is 5 pi/18 to 7 pi/18.
Optionally, the radian of the upper surface of the bump 110 is pi/3.
When the radian of the upper surface of the bump 110 is pi/3, the truncated sample still has enough kinetic energy to be ejected to both sides of the two bumps 110 after colliding with the blade of the cutting mechanism 200.
It should be noted that the working table 100 of the present application may have only two bosses, that is, two bosses are directly fixed on a certain plane, and the two bosses and the plane between the two bosses are formed as the groove 120. The platform 100 of the present application may also be a whole U-shaped structure, with two bosses being the only structure at the upper end, and two bosses and the structure at the lower end forming the groove 120.
Referring to fig. 4, the cutting mechanism 200 includes a cutting member and a first supporting frame 210. Wherein the cutting member is slidably connected to the first support frame 210 such that the cutting edge of the cutting member faces the groove 120.
The two ends of the sample 300 to be cut are respectively placed on the two bumps 110, and when the cutting piece cuts the sample 300 to be cut downwards, the blade can directly fall into the groove 120, so that the blade is prevented from directly impacting the workbench 100 and unnecessary abrasion is avoided.
The cutting member includes a cutter head 220 and a transmission rod 230, the cutter head 220 is connected to the lower end of the transmission rod 230, and the upper end of the transmission rod 230 is slidably connected to the first support frame 210.
In the embodiment shown in fig. 1 and 4, the cutter head 220 is bolted to the lower end of the drive link 230 for easy removal.
The cutter head 220 has a cutting edge, the cutter head 220 is a cylindrical structure arranged transversely, the cutter head 220 includes a top surface, two end surfaces and two side surfaces, the lower end of the transmission rod 230 is connected to the top surface of the cutter head 220, the two side surfaces of the cutter head 220 form a cutting edge, and the two side surfaces are both curved surfaces recessed inwards.
That is, the contact surface between the tool bit 220 and the sample 300 to be cut is a curved surface, and when the tool bit 220 with the curved surface on the side surface is used for cutting the sample 300 to be cut, the whole tool bit 220 cuts the sample from point to line, that is, the tool bit 220 and the sample 300 to be cut are in line contact at each moment, so that the whole cutting process is more labor-saving.
The radian of two side surfaces of the cutter head 220 is 5 pi/18-7 pi/18;
optionally, the two sides of tool tip 220 have a radius of π/3.
When the radian of the two side surfaces of the tool bit 220 is pi/3, the radian cutting edge surface of the tool bit 220 can provide a force which is completely mirrored to the cutting edge surface by the bounced cut-off sample, and finally, the cut-off sample can be respectively arranged at the two sides of the two convex blocks 110.
The transmission rod 230 is a circular truncated cone or a truncated pyramid structure, and the area of the upper end surface of the transmission rod 230 is larger than that of the lower end surface.
The pressure P (pressure) is F (stress)/S (area), and the upper end surface of the transmission rod 230 is under the action of external force, and the deformation generated by the transmission rod is smaller due to the larger area, so that the upper half structure of the transmission rod 230 is more stable and firmer, and can bear larger impact force, so that a larger cutting force can be applied to the sample 300 to be cut, the sample 300 to be cut can be quickly cut, and the phenomenon that the sample 300 to be cut cannot be cut once is reduced.
The first support bracket 210 serves to support and guide the cutting direction of the cutting member.
The first support frame 210 is not limited to be fixed, and may be fixed to the table 100, may be fixed to a plane on which the table 100 is placed, or may be fixed by an external support structure.
The first support frame 210 includes a first bracket 211, a first support plate 212, and a second support plate 213.
In the embodiment shown in fig. 1, the first support 211 has four support rods, and the bottom ends of the four support rods are respectively connected to four corners of the worktable 100. Meanwhile, the structure can be connected with the workbench 100 to form a triangle-like structure, so that the connection stability and reliability of the first support frame 210 and the workbench 100 are improved, and the phenomenon that the first support frame 211 is unstable in support to cause the knocking piece to impact the sample 300 to be cut in a non-working state and be damaged is avoided.
The first support plate 212 is connected to an upper end portion of the first bracket 211, and a first through hole is formed in a middle portion of the first support plate 212.

The second support plate 213 and the first support 211 of the mortise and tenon structure are combined to improve the stability and impact resistance of the whole first support frame 210, so that the whole first support frame can bear larger impact force.
The driving rod 230 is slidably fitted to the first and second through holes such that the driving rod 230 can move up and down in a direction defined by the first and second through holes, and after a striking force is applied to the upper end of the driving rod 230, the driving rod 230 moves down in the direction defined by the first and second through holes, and the cutter head 220 connected to the lower end of the driving rod 230 cuts the sample 300 to be cut down.
Alternatively, the upper end of the driving rod 230 is provided with a boss having a cross-sectional area larger than the first through-hole so that the upper end of the driving rod 230 is not separated from the first through-hole during the downward movement of the driving rod 230. That is, after the driving rod 230 moves downward and the cutting head 220 at the end thereof completes the cutting, the driving rod 230 can support the projection through the first through hole so as not to be separated from the first support frame 210.
Moreover, the length of the transmission rod 230 is less than the distance from the first through hole to the bottom surface of the groove 120 of the worktable 100, so that the blade of the cutter head 220 cannot directly contact the bottom surface of the groove 120 due to insufficient distance in the process of knocking, and the abrasion of the blade is avoided.
The transmission rod 230 is sleeved with the elastic member 214 between the first through hole and the second through hole, the upper end of the elastic member 214 is connected to the transmission rod 230, and the lower end of the elastic member 214 abuts against the second support plate 213.
The elastic member 214 can support the driving rod 230 such that the tool tip 220 is positioned on the upper side of the sample 300 to be cut, when the driving rod 230 and the tool tip 220 are both positioned at the initial position. When a sample needs to be cut off, a knocking force is applied to the upper end of the transmission rod 230, the transmission rod 230 moves downwards along the first through hole and the second through hole, the elastic member 214 deforms and is compressed, the cutter head 220 connected to the lower end of the transmission rod 230 cuts the sample 300 to be cut off downwards, after the knocking force is removed, the elastic member 214 restores to deform, the transmission rod 230 moves upwards along the first through hole and the second through hole, and the transmission rod 230 and the cutter head 220 return to the initial positions.

The sample 300 to be cut can be ejected into the sample receiving boxes 500 on both sides of the weight base 400 after being cut.
The counterweight base 400 is provided with a guide rail near the side wall of the sample receiving box 500, the side wall of the sample receiving box 500 is provided with a guide part, and the sample receiving box 500 is connected to the counterweight base 400 through the guide part and the guide rail part in a matching manner.
Optionally, a sample receiving pad 600 is disposed under the weight base 400.
When the cutting member cuts the sample 300 to be cut downwards, the cutter head 220 acts on the sample 300 to be cut and then applies a huge impact force to the sample 300 to be cut instantly, the impact force is transmitted to the lug 110 supporting the sample, at the contact position of the sample and the lug 110 (the contact position of the lug 110 and the sample 300 to be cut is a line contact position, and the concave bottom of the lug 110 collided when the sample is cut off), the lug 110 generates a reaction force to the sample, so that the cut sample bounces upwards, the bounced sample acts on the blade concave part, the concave part generates a mirror image force to the cut sample, and the cut sample is bounced to the sample receiving box 500. According to the sample receiving box 500, the cut samples are guided to directionally bounce into the sample receiving box by the combined action of the convex blocks 110, the concave parts of the cutting edges and the like, and safety accidents caused by disordered popping of the cut samples are avoided.
Referring to fig. 5, the present embodiment further provides a cutting apparatus 20, which includes a knocking hammer device 700 and the cutting device 10, wherein the knocking hammer device 700 is disposed on the upper side of the cutting mechanism 200. The rapping hammer device 700 can provide a large rapping force to the upper end of the transmission rod 230, and the cutter head 220 connected to the lower end of the transmission rod 230 cuts the sample 300 to be cut such that the cut sample is bounced up to both sides of the two bumps 110.
The cutting device 20 further includes a second supporting frame 800, the second supporting frame 800 includes a third supporting plate 802 and a second bracket 801, a third through hole is provided in the middle of the third supporting plate 802, the hammer device 700 is disposed on the third supporting plate 802 in a manner that the hammer corresponds to the third through hole, and the hammer can be driven to pass through the third through hole to strike the upper end portion of the transmission rod 230.
Note that the fixing method of rapping hammer device 700 is not limited in this application, and it may be fixed by second supporting frame 800 or by an external supporting structure.
The method of cutting the sample using the above cutting apparatus 20 is as follows:
placing the sample 300 to be cut on the worktable 100, and respectively placing two ends of the sample 300 to be cut on the two bumps 110;
pressing the start button of the rapping hammer device 700, the rapping hammer is driven through the third through hole and raps the upper end of the transmission rod 230;
the transmission rod 230 drives the cutter head 220 to move downwards, and the cutter head 220 cuts off the sample 300 to be cut off at a higher speed;
after the sample is cut off, the cut sample interacts with the bump 110, when the cut sample is cut off, an oblique downward acting force is applied to the bump 110, the bump 110 also applies an oblique upward reacting force to the cut sample, under the action of the reacting force, the cut sample bounces to collide with the radian blade face of the tool bit 220, the blade face of pi/3 applies a force which is completely mirror-imaged with the blade face of the cut sample to the cut sample, and finally the cut sample falls into the sample receiving boxes 500 on two sides respectively;
after the striking force is removed, the elastic member 214 is deformed again, the driving rod 230 moves upward along the first and second through holes, and the driving rod 230 and the cutter head 220 return to the initial positions.
In summary, the cut-off device 10 and the equipment in the embodiment of the application can replace manual sample knocking, solve the problem of potential safety hazard in the manual sample knocking process, shorten the sample knocking time and improve the working efficiency.
