Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of steel bar cutting, in particular to a steel bar cutting device. Background Art
[0002] At present, steel bars refer to steel used for reinforced concrete and prestressed reinforced concrete. Their cross-section is circular, sometimes square with rounded corners, including plain round steel bars, ribbed steel bars, and twisted steel bars. Steel bars for reinforced concrete refer to straight bars or coiled steel used for reinforced concrete reinforcement. Their appearance is divided into plain round steel bars and deformed steel bars, and the delivery status is straight bars and coiled steel bars.
[0003] During the production process, due to their long length, steel bars need to be cut into fixed lengths using cutting equipment to facilitate their transportation and packaging.
[0004] When cutting steel bars in the market, most of them are directly transmitted to the cutting machine for fixed-length cutting. However, the cutting machine presses down on the middle of the steel bar, causing the two ends of the steel bar to curl up, thereby accidentally injuring the operator. Therefore, a new technical solution needs to be designed to solve this problem. Utility Model Content
[0005] The purpose of the utility model is to provide a steel bar cutting device to solve the problems raised in the background technology.
[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a steel bar cutting device, comprising a conveying seat, on which a plurality of groups of equally spaced transmission rollers are installed for transmission, a cutting seat is fixedly installed in the middle of the top of the conveying seat, a hydraulic push rod is fixedly installed on the top of the cutting seat, a cutting knife is fixedly installed on the other end of the hydraulic push rod, and support mechanisms are installed on both sides of the cutting seat;
[0007] The supporting mechanism includes an electric push rod fixedly installed in the middle of the bottom of the conveying seat, a support seat fixedly installed at the bottom of the electric push rod, and support rollers rotatably installed on the top of the support seat, and multiple groups of the support rollers correspond to each other with the support platform.
[0008] As an optional solution of the technical solution of the present application, a support platform is fixedly installed at the bottom of the cutting knife, and the support platform corresponds to the cutting knife and can support the steel bar.
[0009] As an optional solution to the technical solution of the present application, limit holes are provided on both sides of the stop seat, and limit rods are movably installed in the two groups of limit holes. The tops of the two groups of limit rods are fixedly installed on the bottom of the conveying seat, so as to limit the stop seat.
[0010] As an optional solution of the technical solution of the present application, limit slide grooves are provided on both sides of the top of the stop seat, and a limit slider is slidably installed in each group of the limit slide grooves. A stop roller is rotatably installed between the two groups of limit sliders corresponding to each other, and the stop roller can be adjusted.
[0011] As an optional solution of the technical solution of the present application, a spring is fixedly installed on the top of each group of the limit sliding blocks, and the top of each group of the springs is fixedly installed on the top of the corresponding limit sliding groove, so as to support the limit sliding block.
[0012] Compared with the prior art, the beneficial effects of the utility model are as follows:
[0013] 1. The technical solution of the present application can transport long steel bars to the cutting seat through multiple sets of rotating transmission rollers on the conveying seat, and manually measure the length of the steel bars to be cut, stop the rotation of the multiple sets of transmission rollers, and drive the hydraulic push rod to push the cutting knife to cut the steel bars. At the same time, the electric push rod in the supporting mechanism is driven to push the stop seat to slowly move upward, so that the stop rollers on the top of the stop seat lift the steel bars, and support both sides of the steel bars to be cut, so as to avoid the two ends of the steel bars being lifted up due to the downward pressure in the middle when the cutting knife cuts the steel bars, thereby accidentally injuring the operator.
[0014] 2. The technical solution of the present application is that a limit slider is slidably installed in the limit slide groove of the group, and a spring is fixedly installed on the top of each group of the limit sliders. When the hydraulic push rod is driven to push the cutting knife to cut the steel bar, the limit slider in the limit slide groove cooperates to buffer the roller rotatably installed between the two groups of limit sliders, so that the roller has space to move downward, avoiding the adjustment of the stop seat too high, which will still cause the two sides of the steel bar to curl up when cutting the steel bar.

DETAILED DESCRIPTION
[0019] See also Figure 1-2 The utility model provides a technical solution: a steel bar cutting device, including a conveying seat 1, on which a plurality of equally spaced transmission rollers 11 are installed, a cutting seat 12 is fixedly installed in the middle of the top of the conveying seat 1, a hydraulic push rod 13 is fixedly installed on the top of the cutting seat 12, a cutting knife 14 is fixedly installed on the other end of the hydraulic push rod 13, and support mechanisms are installed on both sides of the cutting seat 12;
[0020] The supporting mechanism includes an electric push rod 2 fixedly installed in the middle of the bottom of the conveying seat 1, a support seat 21 fixedly installed at the bottom of the electric push rod 2, and a support roller 22 rotatably installed on the top of the support seat 21. Multiple groups of support rollers 22 correspond to the support platform 15. The bottom of the cutting knife 14 is fixedly installed with a support platform 15. The support platform 15 corresponds to the cutting knife 14 and can lift the steel bars.
[0021] In this technical solution, a long steel bar can be transported to the cutting seat 12 through multiple sets of rotating transmission rollers 11 on the conveying seat 1. The length of the steel bar to be cut is manually measured, the rotation of the multiple sets of transmission rollers 11 is stopped, and the hydraulic push rod 13 is driven to push the cutting knife 14 to cut the steel bar. At the same time, the electric push rod 2 in the supporting mechanism is driven to push the support seat 21 to move slowly upward, so that the roller 22 on the top of the support seat 21 lifts the steel bar, and both sides of the steel bar to be cut can be supported, so as to avoid the cutting knife 14 from pressing down on the middle when cutting the steel bar, causing the two ends of the steel bar to tilt up, thereby accidentally injuring the operator.
[0022] In some technical solutions, limiting grooves 3 are provided on both sides of the top of the stopper 21, and a limiting slider 31 is slidably installed in each group of limiting grooves 3. A stop roller 22 is rotatably installed between the two corresponding groups of limiting sliders 31, and the stop roller 22 can be adjusted. A spring 33 is fixedly installed on the top of each group of limiting sliders 31, and the top of each group of springs 33 is fixedly installed on the top of the corresponding limiting groove 3, so as to support the limit slider 31.
[0023] In this technical solution, when the hydraulic push rod 13 is driven to push the cutting knife 14 to cut the steel bar, the limiting slider 31 in the limiting slide groove 3 can be used to buffer the rollers 22 rotatably installed between the two sets of limiting sliders 31, so that the rollers 22 have space to move downward, thereby preventing the seat 21 from being adjusted too high, which will still cause the two sides of the steel bar to curl up when cutting the steel bar.
[0024] In some technical solutions, limiting holes 23 are provided on both sides of the stopper 21, and limiting rods 24 are movably installed in the two groups of limiting holes 23. The tops of the two groups of limiting rods 24 are fixedly installed on the bottom of the conveying seat 1, so as to limit the stopper 21.
[0025] In this technical solution, when the stopper 21 is pushed to move up and down, the stopper 21 can be supported and limited by the stopper 24 in the stopper hole 23 to ensure that the stopper 21 moves up and down in the vertical direction.
[0026] When a steel bar cutting device is used, it should be noted that the utility model is a steel bar cutting device, and each component is a universal standard part or a component known to technical personnel in this field, and its structure and principle can be known to technical personnel through technical manuals or through conventional experimental methods.
[0027] When in use, firstly, the long steel bars can be transported to the cutting seat 12 through the multiple sets of rotating transmission rollers 11 on the conveying seat 1, and the length of the steel bars to be cut is measured manually, and the rotation of the multiple sets of transmission rollers 11 is stopped, and the hydraulic push rods 13 are driven to push the cutting knife 14 to cut the steel bars, and at the same time, the electric push rods 2 in the supporting mechanism are driven to push the stop seat 21 to move up slowly, so that the stop rollers 22 on the top of the stop seat 21 can lift the steel bars, and both sides of the steel bars to be cut can be supported, so as to avoid the cutting knife 14 from cutting the steel bars. The middle part is pressed down, causing the two ends of the steel bar to tilt up, thereby accidentally injuring the operator. At the same time, the limit sliders 31 are slidably installed in the limit slide grooves 3, and the top of each group of limit sliders 31 is fixedly installed with a spring 33. When the hydraulic push rod 13 is driven to push the cutting knife 14 to cut the steel bar, the limit slider 31 in the limit slide groove 3 can cooperate with the limit slider 31 in the limit slide groove 3 to buffer the rollers 22 rotatably installed between the two groups of limit sliders 31, so that the rollers 22 have space to move downward, avoiding the adjustment of the stop seat 21 too high, which will still cause the two sides of the steel bar to tilt up when cutting the steel bar.
