A fixed-length cutting device for aluminum-embedded steel rod machining

Abstract

This utility model relates to the field of aluminum-embedded steel bar processing technology, and provides a fixed-length cutting device for processing aluminum-embedded steel bars. It includes a mounting plate installed on the surface of the cutting device, with bolts fastened to both sides of the mounting plate surface. A support plate is fixed to the surface of the mounting plate, and a first sliding groove block is formed on the surface of the support plate. When using the cutting device to cut aluminum-embedded steel bars, the operator can flexibly use an internal adjustment mechanism depending on whether the core is steel-aluminum coated or aluminum-steel coated. Under the action of the internal adjustment mechanism, the inner top block can extend and the outer top block can retract, or vice versa, thus prioritizing contact between the positioning surface and the steel bar. This avoids deformation of the aluminum under the cutting impact force, preventing deviation between the actual position of the workpiece and the theoretical positioning reference. Furthermore, the connecting mechanism can improve the stability of the positions of the inner and outer top blocks.

Description

Technical Field

[0001] This utility model relates to the field of aluminum-embedded steel bar processing technology, specifically a fixed-length cutting device for processing aluminum-embedded steel bars. Background Technology

[0002] Aluminum-embedded steel bars are a type of composite profile, typically composed of an inner steel bar and an outer aluminum cladding. They combine the high strength and rigidity of steel with the corrosion resistance and ease of processing (such as surface treatment) of aluminum. They are widely used in building structures, machinery manufacturing, rail transportation, and other fields. Fixed-length cutting is the process of cutting the composite bar to a specific length according to actual needs, and it is a key step in the manufacturing process.

[0003] When cutting aluminum-embedded steel bars to a fixed length, an adjustable mechanical baffle needs to be set on the cutting table. The position of the baffle is set by a ruler or CNC system. The workpiece is fixed after one end is pressed against the baffle to achieve a fixed length. However, the elastic modulus of steel (about 200 GPa) is more than 3 times that of aluminum (about 70 GPa). This means that under the same external force (such as clamping force or cutting impact force), the deformation of steel is only about 1 / 3 of that of aluminum. If the positioning surface contacts the aluminum layer, the low rigidity of aluminum will cause local depression, yielding or elastic deformation, causing the actual position of the workpiece to deviate from the theoretical positioning reference. Utility Model Content

[0004] The purpose of this invention is to provide a fixed-length cutting device for processing aluminum-embedded steel bars, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a fixed-length cutting device for processing aluminum-embedded steel bars, comprising a mounting plate installed on the surface of the cutting device, bolts fastened to both sides of the surface of the mounting plate, a support plate fixed to the surface of the mounting plate, a first sliding groove formed on the surface of the support plate, a second sliding groove formed on the other side of the surface of the support plate, an inner top block slidably disposed on the surface of the first sliding groove, and an outer top block slidably disposed on the surface of the second sliding groove, further comprising: An inner adjustment mechanism is provided on one side of the support plate surface for adjusting the position of the inner top block. The surface of the inner adjustment mechanism is provided with an outer adjustment mechanism for adjusting the position of the outer top block. The surface of the support plate is provided with a connecting mechanism for positioning the inner top block and the outer top block.

[0006] Preferably, the inner adjustment mechanism includes an inner adjustment ring that rotates on one side of the support plate surface, a rotating block fixed to the other end of the inner adjustment ring, a first adjustment groove formed on the surface of the inner adjustment ring, a first driving block slidably disposed on the surface of the first adjustment groove, a top rod fixed to the other end of the first driving block, and one end of the top rod fixed to the inner top block.

[0007] Preferably, the external adjustment mechanism includes an external adjustment ring fixed to the surface of the rotating block, a second adjustment groove is provided on the surface of the external adjustment ring, a second driving block is slidably disposed on the surface of the second adjustment groove, a driving ring is fixed to the other end of the second driving block, a plurality of driving rods are fixed on the surface of the driving ring, and the other end of the driving rods is fixed to the outer top block.

[0008] Preferably, the connecting mechanism includes a through hole on the surface of the support plate, a first insertion hole on both sides of the surface of the outer top block, and a second insertion hole on both sides of the surface of the inner top block. A pin is slidably disposed on the surface of the through hole, and a pull head is fixed at one end of the pin.

[0009] Preferably, both sides of the surface of the second slide groove are provided with outer limiting grooves, and both sides of the surface of the outer top block are fixed with outer limiting blocks. The outer limiting groove slides on the surface of the outer limiting block. Both sides of the surface of the first slide groove are provided with inner limiting grooves, and both sides of the surface of the inner adjusting mechanism are fixed with inner limiting blocks. The inner limiting blocks slide on the surface of the inner limiting grooves.

[0010] Preferably, the surface of the pull head is fixed with an anti-slip ring, and the surface of the rotating block is fixed with an anti-slip ridge.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: When using the cutting device to cut aluminum-embedded steel bars, the operator can flexibly use the internal adjustment mechanism according to the steel core aluminum coating or aluminum core steel coating. Under the action of the internal adjustment mechanism, the inner top block can extend and the outer top block can retract, or the outer top block can retract and the outer top block can extend. This prioritizes the positioning surface to contact the steel bar, avoiding deformation of the aluminum under the action of cutting impact force, which would cause the actual position of the workpiece to deviate from the theoretical positioning benchmark. In addition, the stability of the positions of the inner and outer top blocks can be improved by the action of the connecting mechanism. Attached Figure Description

Detailed Implementation

[0014] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.

[0015] Please see Figures 1-4 As shown, a fixed-length cutting device for processing aluminum-embedded steel bars includes a mounting plate 1 installed on the surface of the cutting device. Both sides of the surface of the mounting plate 1 are bolted with fasteners 3. The mounting plate 1 is connected to the cutting device through the fasteners 3. A support plate 2 is fixed on the surface of the mounting plate 1. The support plate 2 can position one end of the aluminum-embedded steel bar. A first groove 4 is opened on the surface of the support plate 2, and a second groove 6 is opened on the other side of the surface of the support plate 2. An inner top block 5 is slidably disposed on the surface of the first groove 4, and an outer top block 7 is slidably disposed on the surface of the second groove 6.

[0016] An inner adjustment mechanism 8 is provided on one side of the surface of the support plate 2 for adjusting the position of the inner top block 5. The inner adjustment mechanism 8 includes an inner adjustment ring 82 that rotates on one side of the surface of the support plate 2. A rotating block 81 is fixed to the other end of the inner adjustment ring 82. A first adjustment groove 83 is provided on the surface of the inner adjustment ring 82. A first driving block 84 is slidably provided on the surface of the first adjustment groove 83. A top rod 85 is fixed to the other end of the first driving block 84. One end of the top rod 85 is fixed to the inner top block 5. When the rotating block 81 rotates, the inner adjustment ring 82 fixed to the surface of the rotating block 81 can rotate. Then, the first driving block 84, which is in contact with the surface of the first adjustment groove 83, can drive the top rod 85 to move. Thus, under the action of the top rod 85, the inner top block 5 moves.

[0017] The surface of the inner adjustment mechanism 8 is provided with an outer adjustment mechanism 9 for adjusting the position of the outer top block 7. The outer adjustment mechanism 9 includes an outer adjustment ring 91 fixed to the surface of the rotating block 81. A second adjustment groove 92 is opened on the surface of the outer adjustment ring 91. A second driving block 94 is slidably disposed on the surface of the second adjustment groove 92. A driving ring 93 is fixed to the other end of the second driving block 94. A plurality of driving rods 95 are fixed on the surface of the driving ring 93. The other end of the driving rods 95 is fixed to the outer top block 7. When the rotating block 81 rotates, the outer adjustment ring 91 fixed to the surface of the rotating block 81 can cause the second adjustment groove 92 to rotate. Then, the second driving block 94, which is in contact with the surface of the second adjustment groove 92, can cause the driving ring 93 and the driving rods 95 to move. Thus, under the action of the driving rods 95, the outer top block 7 moves.

[0018] Since the first adjusting slide 83 and the second adjusting slide 92 are in opposite directions, when the rotating block 81 rotates in one direction, the outer top block 7 and the inner top block 5 can be displaced in opposite directions.

[0019] The surface of the support plate 2 is provided with a connecting mechanism 11 for positioning the inner top block 5 and the outer top block 7. The connecting mechanism 11 includes a through hole 115 on the surface of the support plate 2, a first insertion hole 113 on both sides of the surface of the outer top block 7, and a second insertion hole 114 on both sides of the surface of the inner top block 5. A pin 112 is slidably provided on the surface of the through hole 115. A pull head 111 is fixed to one end of the pin 112. Under the action of the pull head 111, the pin 112 can be displaced, thereby limiting the corresponding first insertion hole 113 and second insertion hole 114 under the restriction of the through hole 115.

[0020] Since there are two of each of the first socket 113 and the second socket 114, it provides assistance for the alternating operation of the inner top block 5 and the outer top block 7.

[0021] The surface of the pull head 111 is fixed with an anti-slip ring 16, and the surface of the rotating block 81 is fixed with an anti-slip ridge 10. Under the action of the anti-slip ring 16, a force point is provided for the use of the pull head 111, and under the action of the anti-slip ridge 10, a force point is provided for the use of the rotating block 81, thereby improving the practicality of the device.

[0022] Both sides of the surface of the second slide groove 6 are provided with outer limiting grooves 12, and both sides of the surface of the outer top block 7 are fixed with outer limiting blocks 15. The outer limiting grooves 12 slide on the surface of the outer limiting blocks 15. Both sides of the surface of the first slide groove 4 are provided with inner limiting grooves 13, and both sides of the surface of the inner adjusting mechanism 8 are fixed with inner limiting blocks 14. The inner limiting blocks 14 slide on the surface of the inner limiting grooves 13. Under the action of the outer limiting grooves 12 and the outer limiting blocks 15, the sliding of the outer top block 7 is limited. Under the action of the inner limiting grooves 13 and the inner limiting blocks 14, the sliding of the inner top block 5 is limited.

[0023] Working principle: When cutting aluminum-embedded steel bars, the operator can flexibly use the internal adjustment mechanism 8 according to the way the aluminum is embedded in the steel bar. If the aluminum is embedded in the inner cavity of the steel bar, the internal adjustment mechanism 8 can be used. Under the action of the internal adjustment mechanism 8, the outer top block 7 extends and the inner top block 5 retracts, so that the outer top block 7 contacts the outer ring of the steel bar. The connecting mechanism 11 is used to stabilize the position of the outer top block 7 and the inner top block 5, forming a positioning block suitable for this situation.

[0024] If the surface of the aluminum-embedded steel rod is such that the steel core is covered with aluminum, the operator can use the internal adjustment mechanism 8 to retract the outer top block 7 and extend the inner top block 5, thereby making the inner top block 5 contact the steel core, and use the connecting mechanism 11 to stabilize the position of the outer top block 7 and the inner top block 5, forming a positioning stop suitable for this situation.

[0025] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model. Any indirect modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the scope of the present utility model shall still fall within the scope of the present utility model.
