Description

Technical Field

[0001] The utility model relates to the technical field of straightening hardware products, in particular to a straightening device for hardware products. Background Art

[0002] In modern Chinese, the term "hardware" generally refers to five metal materials: gold, silver, copper, iron, and tin. These metals are widely used in various industries and daily life due to their physical and chemical properties, hence the name "hardware". Specifically, "hardware" can be divided into two categories: large hardware and small hardware. Large hardware refers to relatively large metal materials, such as steel plates, rebar, flat iron and other steel materials. Small hardware includes construction hardware, household hardware, locks, nails, wire and other tools and accessories. Rebar refers to steel used for reinforced concrete and prestressed reinforced concrete. Its cross-section is round, and sometimes square with rounded corners. Rebar is widely used in various building structures, especially large, heavy, lightweight, thin-walled and high-rise building structures. Small diameter rebar is coiled and needs to be straightened before use.

[0003] In the production process of steel bars in the prior art, the finished steel bars need to be straightened before use to meet market requirements. At present, in the straightening work of steel bars, the steel bars are generally clamped by clamping rollers, and then the steel bars are pulled by a traction device to make the steel bars slide between the two clamping rollers, and the steel bars are straightened through the clamping range of the clamping rollers. However, the existing steel bar straightening device can only pull steel bars of the same diameter. For steel bars of different diameters, it is necessary to replace clamping rollers of different sizes to operate, which wastes time and materials. Utility Model Content

[0004] Based on this, the purpose of the present utility model is to provide a straightening device for hardware products to solve the technical problem that the existing steel bar straightening device can only pull steel bars of the same diameter. For steel bars of different diameters, it is necessary to replace clamping rollers of various sizes to operate, which wastes time and materials.

[0006] By adopting the above technical solution, the connecting rod is pushed to move by the output end of the electric telescopic rod, and the two sliders are driven to move synchronously by the connecting rod, so that the slider adjusts the position of the second rotating shaft, thereby adjusting the longitudinal distance between the two rollers. The rollers are controlled to drive the connecting plate to slide on the connecting rod, the lateral distance of the rollers is adjusted, and the screws are threaded in the nearest threaded holes to fix the distance between the two sets of half rollers. By adjusting the lateral and longitudinal distances of the two rollers, steel bars of different diameters can be straightened.

[0007] Furthermore, the two groups of sliders are fixedly connected by a connecting rod, the two ends of the second rotating shaft are respectively rotatably connected to the two sliders, an electric telescopic rod is fixedly provided at the bottom of the first support frame, the output end of the electric telescopic rod is fixedly connected to a clamping block, and the clamping block is fixedly connected to the top of the connecting rod.

[0008] By adopting the above technical solution, the electric telescopic rod plays a role in enabling the slider to slide up and down in the movable groove.

[0009] Furthermore, the roller is slidably connected to a connecting rod, and the connecting rod passes through the roller. The connecting rod is provided with a threaded hole, and the top end of the connecting rod is fixedly connected to a connecting plate, and the connecting plate and the connecting rod are fixedly connected by screws.

[0010] By adopting the above technical solution, the connecting rod plays a role in adjusting the lateral distance between the rollers.

[0011] Furthermore, a fixing block is fixedly connected to the top of the base, and a limiting ring is fixedly connected to the top of the fixing block.

[0012] By adopting the above technical solution, the limiting ring plays a role in limiting the position of the steel bars, thereby achieving the effect of preventing the steel bars from moving too violently.

[0013] Furthermore, a second support frame is fixedly connected to the top of the base, and rollers are movably connected to both sides of the second support frame.

[0014] By adopting the above technical solution, the two sets of rollers play a role in secondary straightening of the steel bars.

[0015] Furthermore, a motor is fixedly connected to the top of the second support frame, a second bevel gear is fixedly connected to the output end of the motor, and a first bevel gear is fixedly connected to one end of the roller shaft, and the first bevel gear is meshed with the second bevel gear.

[0016] By adopting the above technical solution, the motor drives the two sets of rollers through the bevel gears.

[0017] In summary, the utility model mainly has the following beneficial effects: the utility model pushes the connecting rod to move through the output end of the electric telescopic rod, and drives the two sliders to move synchronously through the connecting rod, so that the slider adjusts the position of the second rotating shaft, thereby adjusting the longitudinal distance between the two rollers, and drives the connecting plate to slide on the connecting rod by controlling the rollers to adjust the lateral distance of the rollers, and fixes the screws in the nearest threaded holes to fix the distance between the two groups of half rollers.
