DETAILED DESCRIPTION

[0032] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0033] Embodiment 1, as Figure 1 and Figure 2As shown, a construction engineering bar material cutting device comprises a shell 1, a discharging seat 2 is fixedly connected to the lower end of the shell 1, a discharging platform 21 is fixedly connected to the bottom wall of the discharging seat 2, and a cutting assembly 3 is fixedly installed on the rear side wall of the inner surface of the shell 1. By setting the cutting assembly 3, the bar materials placed inside can be uniformly cut during the cutting process, and after the cutting is completed, the materials can be dropped in an orderly manner, so that the dropped materials are more regular, which is convenient for subsequent unified collection, thereby improving the cutting efficiency;

[0034] The rear end of the housing 1 is fixedly connected with a baffle 4, and the rear end of the baffle 4 is fixedly installed with a pusher assembly 5. The pusher assembly 5 is provided to cooperate with the front end of the bar material to be uniformly aligned before cutting, so that the specifications of the bar materials cut subsequently are consistent, and the waste materials generated by the cutting can fall out of the pusher assembly 5, thereby achieving the effect of discharging finished materials and waste materials in different areas;

[0035] A driving assembly 6 is provided on the left side of the shell 1. Through the set driving assembly 6, it can cooperate with the cutting assembly 3 and the pushing assembly 5 for driving. When cutting, the pushing assembly 5 contracts and does not affect the normal cutting process of the cutting assembly 3. After the cutting is completed, when the next batch of rods are placed in the shell 1, the driving assembly 6 can assist the pushing assembly 5 to align the placed rods, thereby improving the subsequent cutting efficiency.

[0036] Embodiment 2: This embodiment is based on embodiment 1 and is for achieving the purpose of intermittent cutting of bar materials and uniform blanking.

[0037] For details, see Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 Five rod placement grooves 41 are opened in a linear array on the upper end of the baffle 4, a special-shaped hole 42 is opened at the lower left end of the baffle 4, a rectangular hole 43 is opened at the front edge of the lower left end of the shell 1, and a rectangular groove 44 is opened in the middle of the rear side wall of the inner surface of the shell 1, and the rectangular hole 43 is connected to the rectangular groove 44.

[0038] Furthermore, the cutting assembly 3 includes six blanking plates 31 fixedly connected to the rear side wall of the inner surface of the shell 1 in a linear array, a slide rod 32 is slidably connected to the inner surface of the rod placing groove 41, six support plates 33 are fixedly connected to the rear end of the slide rod 32 in a linear array, six guide plates 34 are fixedly connected to the lower part of the rear side wall of the inner surface of the shell 1 in a linear array, a carrying plate 35 is fixedly connected to the lower part of the rear ends of the six support plates 33, six mounting plates 36 are fixedly connected to the upper end of the carrying plate 35 in a linear array, and a number of cutting discs 37 are rotatably connected to the right side of the front end of the five mounting plates 36 from left to right, and a tilting table 38 is fixedly connected to the lower part of the ends of the six mounting plates 36 close to each other, a connecting plate 1 39 is fixedly connected to the lower part of the left end of the mounting plate 36 located on the far left, and a connecting plate 2 30 is fixedly connected to the left end of the slide rod 32.

[0039] Furthermore, the discharging platform 21 is arranged in an inclined shape, and the height of the left side of the discharging platform 21 is greater than the height of the right side.

[0040] The bar material to be processed is placed into the shell 1, and then the bar material will fall into the gap formed by the six blanking plates 31. Since the leftmost blanking plate 31 and the rightmost blanking plate 31 are respectively in contact with the left wall and the right wall of the inner surface of the shell 1, the bar material will not leak out from the leftmost and rightmost sides. After the bar material falls into the gap formed between the six blanking plates 31, the driving component 6 can be started to drive the cutting component 3 and the pushing component 5 to start operation, and the pushing component 5 can make the front end of the bar material fit with the front side wall of the inner surface of the shell 1. In the process of the front end of the bar material fitting with the front side wall of the inner surface of the shell 1, the sliding rod 32 slides in the rod placing groove 41, which will drive the six support plates 33 fixedly connected at the rear end thereof to move to the bottom of the gap formed between the six blanking plates 31, thereby achieving the effect of receiving the bar material.

[0041] When the driving assembly 6 is started in the reverse direction, the slide bar 32 drives the six supporting plates 33 fixedly connected to its rear end to leave the gap formed between the six blanking plates 31. At the same time, since the rear ends of the six supporting plates 33 are fixedly connected to the supporting plate 35, and the upper end of the supporting plate 35 is fixedly connected to six mounting plates 36 in a linear array, and the front ends of the five mounting plates 36 from left to right are all linearly connected to a number of cutting discs 37. Therefore, when the supporting plate 35 drives the six mounting plates 36 to move to the right with the slide bar 32, a number of cutting discs 37 can be started to cut the rods passing through their surfaces, and the remaining materials produced after cutting will slide out from the surface of the tilting table 38. After the cutting is completed, the driving assembly 6 is started again for forward transmission, and then the above-mentioned working steps of fitting the front end of the rods with the front side wall of the inner surface of the shell 1 are repeated, thereby achieving the effect of batch cutting.

[0042] The finished materials after cutting will fall into the gaps formed between the six guide plates 34 in sequence when the six support plates 33 leave the gaps formed by the six blanking plates 31. As can be seen from the above, the discharge table 21 fixedly connected to the bottom wall of the discharge seat 2 is arranged in an inclined shape, and the height of the left side of the discharge table 21 is greater than the height of the right side. Therefore, the rods in the gaps formed between the six guide plates 34 will roll out of the outer side of the shell 1 from the upper end of the discharge table 21 from left to right in sequence, and finally the cut rods can be collected uniformly.

[0043] The above-mentioned fixing of a plurality of cutting discs 37 is a conventional arrangement in the prior art, and its working principle is as follows:

[0044] 1. Rotational power: the cutting disc 37 is driven by an electric motor to rotate at a high speed. The cutting disc 37 usually rotates at a speed of several thousand to tens of thousands of revolutions per minute, which can generate sufficient cutting power;

[0045] 2. During the cutting process, when the cutting disc 37 comes into contact with the material to be cut, the sharp edge generated by the high-speed rotation of the cutting disc 37 exerts a huge shear force on the surface of the material, and the hard particles on the cutting disc 37, such as diamond, tungsten carbide, etc., rub, break and peel against the surface of the material, so that the material is gradually cut;

[0046] 3. Precision and effect. The sharpness, material and design of the cutting disc 37 have an important influence on the cutting precision and effect. A sharp cutting disc 37 can cut the material more smoothly.

[0047] Therefore, the several cutting discs 37 mentioned above are all conventional designs in the prior art, and their specific installation methods, circuit connection methods and control methods are all conventional designs, which will not be elaborated in detail in this solution.

[0048] Embodiment 3: Based on Embodiment 2, this embodiment is for achieving the purpose of simultaneously driving the cutting assembly 3 and the pushing assembly 5 to perform cutting processing.

[0049] For details, see Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 7 , Figure 8 , Fig. 9 and Fig.10The pushing assembly 5 includes a C-shaped plate 51 fixedly connected at the left edge and the right edge of the rear end of the baffle 4, five C-shaped grooves 52 are linearly arranged on the upper end of the C-shaped plate 51, and five circular holes 53 are linearly arranged on the upper and lower parts of the rear end of the C-shaped plate 51. The inner surfaces of the ten circular holes 53 are slidably connected with guide rods 54, and the front ends of the guide rods 54 located on the upper side and the lower side from left to right are fixedly connected with a pushing plate 55. The upper and lower parts of the ends of the rear ends of the five pushing plates 55 that are close to the front side wall of the inner surface of the C-shaped plate 51 are fixedly connected with ten springs 56, and the ten springs 56 are respectively located on the outsides of the ten guide rods 54, and the rear parts of the outer surfaces of the ten guide rods 54 are slidably connected with a top plate 57. The rear parts of the outer surfaces of the ten guide rods 54 are fixedly connected with top blocks 58, and the ten top blocks 58 are located on the rear side of the top plate 57.

[0050] Furthermore, the driving assembly 6 includes a rectangular rod 61 fixedly connected to the front end of the connecting plate 2 30 and the connecting plate 1 39, a heat dissipation shell 62 is fixedly connected to the lower left end of the C-shaped plate 51, and a motor 63 is fixedly connected to the top wall of the heat dissipation shell 62, and a support rod 64 is fixedly connected to the lower left end of the C-shaped plate 51. The support rod 64 is located on the lower side of the heat dissipation shell 62, and a gear 65 is rotatably connected to the left side of the lower end of the support rod 64. The output end of the motor 63 passes through the support rod 64 through a coupling and is fixedly connected to the upper end of the gear 65. The left ends of the C-shaped plate 51 and the baffle 4 are slidably connected to a rack 1 66, and the rear right end of the rack 1 66 is fixedly connected to the left end of the top plate 57, and the rear end of the connecting plate 1 39 is fixedly connected to a rack 2 67, and the rack 1 66 and the rack 2 67 are both meshed with the gear 65.

[0051] Furthermore, the second connecting plate 30 is slidably connected to the inner cavity of the rectangular hole 43 , and the first connecting plate 39 and the second rack 67 are both slidably connected to the inner cavity of the special-shaped hole 42 .

[0052] Furthermore, the five C-shaped grooves 52 and the five rod placing grooves 41 are aligned with each other.

[0053] Furthermore, outer surfaces of the five push plates 55 are fixedly connected with rubber pads, and the five push plates 55 cooperate with the five rod placing grooves 41 .

[0054] By starting the motor 63, the output end of the motor 63 drives the gear 65 fixedly connected thereto to rotate through the coupling, and the support rod 64 rotatably connected to the gear 65 plays a limiting role, and the support rod 64 is fixedly connected to the lower left end of the C-shaped plate 51, and at the same time provides sufficient supporting force. When the gear 65 rotates, it can be known from the above that the rack 1 66 and the rack 2 67 are meshed with the gear 65. Therefore, when the output end of the motor 63 drives the gear 65 to rotate forward, the rack 2 67 drives the connecting plate 1 39 fixedly connected thereto to move rightward in the corresponding special-shaped hole 42, and the rack 1 66 slides on the C-shaped plate 51 and the left end of the baffle 4, and drives the top plate 57 fixedly connected thereto to move backward. Since the rectangular rod 61 is fixedly connected to the connecting plate 2 30 and the connecting plate 1 39, the above-mentioned cutting steps can be realized.

[0055] When the top plate 57 moves backward, it can simultaneously push the ten top blocks 58 on the rear side thereof to move backward, and the ten top blocks 58 can drive the guide rods 54 fixedly connected thereto to move backward. At the same time, the two springs 56 fixedly connected to the rear end of the push plate 55 on the same side are squeezed and contracted, and the ten guide rods 54 pass through the corresponding circular holes 53. At this time, the five push plates 55 all move from the frontmost side of the five C-shaped grooves 52 opened at the upper end of the C-shaped plate 51 to the rearmost side thereof. As can be seen from the above, the five C-shaped grooves 52 and the five release The rod grooves 41 are aligned with each other, so the rods to be processed can be placed in the cavity formed by the C-shaped groove 52 and the rod placing groove 41 in sequence, and the gaps formed by the six blanking plates 31 are aligned with the cavity formed by the C-shaped groove 52 and the rod placing groove 41 in an up-down manner, so the rods can slide downward and be received by the six support plates 33, and then the received rods will be cut by a plurality of cutting discs 37, and the remaining material produced after cutting will tilt downward from the rod placing groove 41, and then fall from the opening on the lower side of the C-shaped plate 51;

[0056] When the motor 63 is then started to reverse, the gear 65 drives the rack 2 67 and the connecting plate 1 39 to move leftward, and the gear 65 drives the rack 1 66 to move forward. When the rack 1 66 moves forward, it will drive the top plate 57 fixed thereto to move forward. When the top plate 57 moves forward, the ten springs 56 will gradually no longer be squeezed, and then drive the push plate 55 fixed thereto to move forward, and the corresponding guide rod 54 plays a role of limiting guide. When the push plate 55 moves forward until it returns to its initial state, it can be seen from the above that the five push plates 55 cooperate with the five rod placing grooves 41, and because the lengths of the rods are inconsistent, the push plate 55 will be limited to follow the spring 56 to rebound to the extent of the inside of the rod placing groove 41, but the spring 56 will always release the squeezing force forward, prompting the push plate 55 to push the rod forward, so that the front end of the rod fits with the front side wall of the inner surface of the shell 1, thereby facilitating subsequent cutting work;

[0057] In order to prevent the push plate 55 from slipping or uneven force when it is attached to the rear end of the bar, the present invention has rubber pads fixedly connected to the outer surfaces of the five push plates 55. The rubber pads can provide sufficient buffer space and prevent slipping when squeezing the bar, thereby improving subsequent cutting efficiency.

[0058] The rubber pad mentioned above is a conventional setting in the prior art, and its characteristics are as follows:

[0059] 1. Good elasticity

[0060] One of the most notable properties of rubber pads is their excellent elasticity. Rubber materials can deform when subjected to external forces, but can quickly return to their original shape. This property enables rubber pads to effectively absorb shock and vibration, and they are often used in shock-absorbing pads and vibration isolation pads.

[0061] 2. Wear resistance

[0062] Rubber pads have good wear resistance and can withstand certain friction without being easily damaged. Therefore, they are often used in parts of industrial machinery and vehicles to reduce wear and damage caused by friction.

[0063] 3. Corrosion resistance

[0064] Rubber materials have strong chemical resistance and can resist corrosion from a variety of acids, alkalis, oils and solvents, which makes the sealing and protective role of rubber pads very important in the chemical, automotive and other industries;

[0065] 4. Good sealing performance

[0066] The elasticity of the rubber pad enables it to fit closely with the contact surface after installation, and has good sealing performance. It can prevent the leakage of liquid and gas, and is often used as a sealing gasket, sealing ring, etc.

[0067] 5. High and low temperature resistance

[0068] The temperature resistance of rubber pads varies depending on the type of material. Generally speaking, rubber pads can withstand certain high and low temperature environments, especially some special high or low temperature resistant rubbers, which can maintain good performance in extreme environments;

[0069] 7.Aging resistance

[0070] Over time, rubber pads may age and lose elasticity and strength due to factors such as ultraviolet rays, oxygen, and temperature changes. However, using the right rubber formula and additives can significantly improve their aging resistance.

[0071] 8. Electrical insulation

[0072] Some types of rubber pads have good electrical insulation properties and can therefore be used as electrical isolation and protection materials in electrical equipment;

[0073] 9. Tensile strength

[0074] Rubber pads have a certain tensile strength and can withstand a certain external force without easily breaking. Although their tensile strength is not as good as that of metal materials, it is sufficient to meet the needs of general working environments.

[0075] It should be noted that the specific installation method of the motor 63, the circuit connection method and the control method used in the present invention are all conventional designs and will not be elaborated in detail in the present invention.

[0076] The above shows and describes the basic principles and main features of the present invention and the advantages of the present invention. It should be understood by those skilled in the art that the present invention is not limited to the above embodiments. The above embodiments and descriptions are only for explaining the principles of the present invention. Without departing from the spirit and scope of the present invention, the present invention may have various changes and improvements, which fall within the scope of the present invention to be protected.
