Description

TECHNICAL FIELD

[0001] The utility model relates to building steel bar processing technical field especially relates to a building steel bar processing equipment. BACKGROUND

[0002] In the construction engineering, the steel bars are cut according to certain size according to the length and quantity of the steel bars in the design drawing. The steel bar cutting can adopt a steel bar cutting machine, and the steel bars with small diameter can also be cut by a manual cutting device or a grinding wheel cutting machine.

[0003] The existing processing equipment is integrally provided with a cutting assembly in the form of spring reverse pushing reset to save the trouble of manually sliding and resetting the cutting assembly after cutting processing is completed. When the cutting assembly is driven to cut by sliding the hand, the reset spring of the cutting assembly needs to be compressed. In order to make the above operation more convenient and labor-saving, the reset spring is mostly provided in the form of slightly greater elastic force than the gravity of the cutting assembly. However, the problem caused thereby is that the reset spring cannot stably push the cutting assembly to remain in the high position state after the cutting assembly is reverse pushed and reset, so that the cutting assembly will be unstable in the up-down sliding state due to the rotating vibration force or other stress acting on it when it is reset to the high position, which can cut the hand that feeds or adjusts the steel bar above the operation table, generating a safety hazard. The existing processing equipment cannot solve the above problems, and the safety and practicability of operation and use are poor. UTILITARIAN CONTENT

[0004] Therefore, the utility model provides a building steel bar processing equipment to solve the problem of poor safety and practicability of operation and use of the existing processing equipment.

[0005] The technical scheme provided by the utility model is as follows: a building steel bar processing equipment specifically comprises a table plate, two short side parts of the top end of the table plate are symmetrically welded with vertical support columns, and a sliding mounting frame that is reverse pushed and reset by a spring is slidably installed on the two vertical support columns.

[0006] The cutting motor is arranged on the sliding mounting frame, a cutting saw blade is fixedly sleeved on the first end portion of the rotating shaft of the cutting motor, two L-shaped positioning rods are symmetrically welded on the top ends of the two vertical supporting columns, two triangular stop blocks are symmetrically welded on the bottom side portions of the two L-shaped positioning rods, a N-shaped handle frame is welded on the sliding mounting frame, two square sliding sleeves are symmetrically slidably arranged on the two longitudinal side rods of the N-shaped handle frame, two protruding transmission rods are symmetrically welded on the two square sliding sleeves, and a N-shaped driving frame is welded on the two protruding transmission rods.

[0007] Further, the sliding mounting frame is composed of two symmetrically arranged transverse supporting rods and a ring-shaped bearing seat welded between the two transverse supporting rods, the cutting motor is fixedly connected with the back side of the ring-shaped bearing seat, and the tail ends of the two longitudinal side rods of the N-shaped handle frame are welded with the transverse supporting rods.

[0008] Two auxiliary mounting rods are symmetrically welded on the two transverse supporting rods near the N-shaped handle frame, and the two U-shaped sliding frames are slidably matched with the two auxiliary mounting rods.

[0009] Further, a bearing is embeddedly arranged in the ring-shaped bearing seat, and the rotating shaft of the cutting motor is assembled with the inner ring of the bearing.

[0010] Further, two N-shaped ground contact frames are symmetrically welded on the bottom two short side positions of the table plate.

[0011] Further, two symmetrically arranged threaded driving shafts are threadedly assembled on the two mounting ear blocks, and clamping plates are welded on the first ends of the two threaded driving shafts.

[0012] Further, the bottom side of the clamping plate is slidably attached to the top end of the table plate.

[0013] The building steel bar processing equipment provided by the utility model has the following beneficial effects:

[0014] I. When the two trapezoidal positioning blocks slide through the two triangular blocks, the two trapezoidal positioning blocks lose the pushing and retaining force from the two triangular blocks, are pushed back by the compressed spring, are reset to slide back, and are inserted into the top end of the two triangular blocks, so that the sliding mounting frame and the cutting assembly are stably positioned and retained at the high position after sliding back, which can avoid that the pushing and retaining force of the two springs on the two vertical support columns is too small to stably push and retain the sliding mounting frame and the cutting assembly at the high reset state, and the cutting assembly is likely to be cut by the hands that load or slide the steel bars above the operation table in the unstable sliding state, which generates a safety hazard, and helps to improve the operation safety and practicality of the steel bar processing equipment.

[0015] II. The U-shaped drive frame is arranged in the U-shaped handle frame, and the transversely arranged handle rods on the two are arranged close to each other, so that the hands can drive the U-shaped drive frame to release and unlock the cutting assembly without moving when the cutting assembly is driven to cut by sliding down the U-shaped handle frame, which helps to further simplify the operation steps of the steel bar processing equipment and further improve the convenience and efficiency of operation.

[0037] Preferably, the sliding mounting frame 2 is composed of two symmetrically arranged horizontal supporting rods 201 and a ring-shaped bearing seat 202 welded between the two horizontal supporting rods 201, the cutting motor 7 is fixedly connected with the back side of the ring-shaped bearing seat 202, and the tail ends of the two longitudinal side rods of the U-shaped handle frame 203 are fixedly welded with the horizontal supporting rods 201; the positions close to the U-shaped handle frame 203 on the two horizontal supporting rods 201 are symmetrically welded with two auxiliary mounting rods 2011, and the two U-shaped sliding frames 6 are slidably penetrated with the two auxiliary mounting rods 2011.

[0038] Preferably, a bearing is embedded and installed in the ring-shaped bearing seat 202, and the rotating shaft of the cutting motor 7 is penetratively assembled with the inner ring of the bearing.

[0039] In the second implementation, the following contents are added compared with the first implementation:

[0040] The bottom two short side positions of the table plate 1 are symmetrically welded with two U-shaped handle frames 203, the top ends of the table plate 1 are symmetrically welded with two mounting ear blocks 103, two symmetrically arranged threaded driving shafts 104 are penetratively installed on the two mounting ear blocks 103 in the form of threaded screwing, and the first ends of the two threaded driving shafts 104 are welded with clamping plates 105; the bottom side of the clamping plate 105 is slidably attached to the top end of the table plate 1.

[0041] Preferably, the two horizontal supporting rods 201 are fixedly installed with semicircular protective covers 3, and the semicircular protective covers 3 are sleeved on the upper half of the cutting saw blade 4.

[0042] The working principle, specific details, implementation steps, functions and mutual relationships of each feature, and the role played in the implementation of the present application are described and explained in detail as follows:

[0043] The base plate 1 and the two U-shaped grounding frames 101 together constitute an operating table; when the two threaded drive shafts 104 rotate in opposite directions, the two clamping plates 105 can be driven to slide relative to each other, so as to tighten or loosen the steel bars placed between the two clamping plates 105 for cutting processing; in use, first, the steel bars to be cut are placed between the two clamping plates 105, and the steel bars are clamped and fixed by the two clamping plates 105, then the cutting motor 7 is started, and the sliding mounting frame 2 is driven to slide downward by the U-shaped handle frame 203; when the sliding mounting frame 2 is driven to slide downward, the two springs sleeved on the two vertical support columns 102 are compressed; when the cutting operation is completed, the U-shaped handle frame 203 is loosened, and the two springs drive the sliding mounting frame 2, the cutting motor 7 and the cutting saw blade 4 to automatically slide upward and reset, which can save the trouble of manually sliding upward and resetting the cutting assembly composed of the cutting motor 7 and the cutting saw blade 4, and is convenient to operate and use, which is helpful to simplify the operation and use steps of the steel bar processing equipment and improve the cutting processing efficiency of the steel bar processing equipment to a certain extent.

[0044] In the process of driving the sliding mounting frame 2 to slide upward and reset, the two trapezoidal positioning blocks 601 slide upward synchronously with the sliding mounting frame 2; in this process, when the inclined surfaces of the two trapezoidal positioning blocks 601 abut against the inclined surfaces of the two triangular blocks 501, the two trapezoidal positioning blocks 601 and the U-shaped sliding frame 6 can be driven to slide towards each other by the guiding principle of the inclined surfaces; when the two trapezoidal positioning blocks 601 are driven to slide towards each other, a space for the upward sliding of the two trapezoidal positioning blocks 601 can be left between the two trapezoidal positioning blocks 601 and the two triangular blocks 501; at this time, the two trapezoidal positioning blocks 601 can slide upward through the two triangular blocks 501 by means of the space, so as to avoid the interference of the two triangular blocks 501 and affect the normal upward sliding reset of the sliding mounting frame 2 and the cutting assembly; when the two trapezoidal positioning blocks 601 slide towards each other, the springs sleeved on the two U-shaped sliding frames 6 are compressed; after the two trapezoidal positioning blocks 601 slide upward through the two triangular blocks 501, the two trapezoidal positioning blocks 601 lose the pushing and retaining force from the two triangular blocks 501, are driven to slide back to the original position by the compressed springs, and are inserted into the top ends of the two triangular blocks 501, so as to stably position and retain the sliding mounting frame 2 and the cutting assembly at a high position after upward sliding reset (see Figure 1 and Figure 6), which can avoid the situation that the counter-thrust of the two springs (the total weight of the sliding mounting frame 2 and the cutting assembly is slightly greater than the elastic force of the two springs, and the reason has been explained in the background) is too small to keep the sliding mounting frame 2 and the cutting assembly stably pushed to the high reset state, causing the cutting assembly to slide up and down unstably due to its own rotating vibration force or other stresses acting on it, which may cut the hands of the operator who is feeding or adjusting the steel bars above the operation table, generating a safety hazard, and helping to improve the safety and practicality of the steel bar processing equipment.

[0045] When the cutting assembly is positioned in the high reset state by the two trapezoidal positioning blocks 601 for re-cutting, the two trapezoidal positioning blocks 601 and the two triangular blocking blocks 501 need to be separated to release the cutting assembly; the U-shaped sliding frame 6, the two square sliding sleeves 205, the two connecting rods 2052 and the U-shaped driving frame 204 are connected together to form two sets of crank slider mechanisms, through which the U-shaped driving frame 204 can drive the two U-shaped sliding frames 6 to slide towards each other, and the two trapezoidal positioning blocks 601 and the two triangular blocking blocks 501 are separated, completing the release and unlocking of the cutting assembly; the U-shaped driving frame 204 is arranged inside the U-shaped handle frame 203, and the horizontal handle bars on the two are arranged close to each other, which enables the hands to drive the U-shaped driving frame 204 to release and unlock the cutting assembly without moving when the cutting assembly is driven to slide down through the U-shaped handle frame 203 for cutting operation, which helps to further simplify the operation steps of the steel bar processing equipment and further improve the convenience and efficiency of its operation.
