AI Technical Summary
After the double-size bar runs through the long-distance output roller, the head is uneven, resulting in an increase in cold shear loss, affecting the scale rate and material yield.
The baffle device is equipped with a cylinder-driven lifting and a buffer, which is used to smooth the head of the double bar before the cold shear to prevent it from spreading out during impact and cushion the impact force of the baffle.
Effectively reduce cold shear losses, improve scale rate and material formation rate, protect the bracket from dispersing the rod, and reduce baffle damage.

Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of bar production equipment, in particular to a device for leveling the head of threaded steel bars at the front end of a cold shearing machine. Background Art
[0002] There is a bar production line in which the output roller length between the cooling bed and the cold shear is about 50 meters. Due to the long length of the output roller, the friction and running speed of the groups of double-length bars are different when running on the output roller, which makes the heads of the double-length bars often uneven when they reach the cold shear. When the heads of the groups of double-length bars are uneven, they directly enter the cold shear for shearing, which can easily result in a large amount of head cutting or the tail section of the finished product is not enough to the fixed length, thereby generating excessive cold shearing loss. The cold shearing loss not only generates extra waste, but also lowers indicators such as the fixed length rate and the yield rate, affecting the company's economic and brand benefits. Utility Model Content
[0003] The purpose of the utility model is to provide a head leveling device for threaded steel bars at the front end of a cold shearing machine, which can solve the problem that the heads of double-length bars are not level when they arrive at the cold shearing machine after running a long distance on an output roller, thereby generating excessive cold shearing loss.
[0004] In order to solve the above problems, the technical solution adopted by the utility model is: the device for leveling the threaded steel head at the front end of the cold shearing machine includes a baffle driven to rise and fall by a cylinder, and each end of the baffle is provided with a group of protective components, each group of the protective components includes two protective brackets, and the two protective brackets are respectively arranged on both sides of the baffle, and a buffer is provided on the inner side of each protective bracket.
[0005] In the above technical solution, a more specific technical solution may also be: the buffer includes a spring steel block fixedly connected to the protection bracket, and the spring steel block is provided with a rubber buffer head at one end facing the baffle.
[0006] Furthermore, there are two cylinders, and the two cylinders are arranged relatively on the outside of the protective component.
[0007] Furthermore, a fork is provided at the outer end of the piston rod of the cylinder, and the lower parts of the two ends of the baffle are clamped in the fork and connected to the fork via a pin.
[0008] Furthermore, the top width of the protection bracket is smaller than the bottom width.
[0009] Furthermore, the cylinder body of the cylinder is fixed on the cylinder base.
[0010] Furthermore, the tops of both ends of the baffle are provided with lifting ears.
[0011] Due to the adoption of the above technical solution, the present invention has the following beneficial effects compared with the prior art:
[0012] This utility model can flatten the heads of grouped double-length bars before they enter the cold shear, effectively reducing shearing losses and improving both the cut-to-length ratio and the yield rate. The protective bracket prevents the double-length bars from scattering and falling off the output rollers due to excessive impact force when striking the baffle. The baffle also experiences significant impact force when struck by the double-length bars, and the buffer acts as a buffer and limiter. BRIEF DESCRIPTION OF THE DRAWINGS
[0013] Figure 1 This is a schematic diagram of the structure of the utility model
[0014] Figure 2 yes Figure 1 Left view of . DETAILED DESCRIPTION
[0015] The present invention will be further described below in conjunction with the accompanying drawings:
[0016] like Figure 1 and Figure 2 The threaded steel head leveling device at the front end of the cold shear shown includes a baffle 2 driven to rise and fall by a cylinder 1, and a group of protective components are respectively provided at the two ends of the baffle 2. Each group of protective components includes two protective brackets 3, and the two protective brackets 3 are respectively provided on both sides of the baffle 2. A buffer is provided on the inner side of each protective bracket 3, and the buffer includes a spring steel block 4 fixedly connected to the protective bracket 3, and the spring steel block 4 is provided with a rubber buffer head 5 at the end facing the baffle 2.
[0017] There are two cylinders 1, which are arranged opposite to each other on the outside of the protective component. A fork 6 is provided at the outer end of the piston rod of the cylinder 1. The lower parts of the two ends of the baffle 2 are clamped in the fork 6 and connected to the fork 6 through a pin shaft. The cylinder body of the cylinder 1 is fixed on the cylinder base 7.
[0018] In order to ensure the bearing capacity of the protection bracket 3 when subjected to impact, the top width L1 of the protection bracket 3 is smaller than the bottom width L2.
[0019] In order to facilitate the lifting of the baffle 2, lifting ears 8 are provided on the top of both ends of the baffle 2.
[0020] In actual use, the front and rear connecting covers of the output roller are removed at a position of 2 to 5 meters from the front end of the cold shear machine, and then the utility model is installed. Before the double-length bars pass through the output roller and reach the utility model, the cylinder 1 is started to drive the baffle 2 to rise. After the double-length bars arrive, they hit the baffle 2, so that the heads of the grouped double-length bars remain flush. Then the cylinder 1 drives the baffle 2 to descend, and the double-length bars continue to move forward and enter the cold shear machine for shearing.
[0021] The utility model can flatten the heads of grouped double-length bars before they enter the cold shearing machine, effectively reducing shearing losses and improving both the cut-to-length ratio and the yield rate. The protective bracket 3 prevents the double-length bars from scattering and falling off the output roller table due to excessive impact force when striking the baffle 2. The baffle 2 also experiences significant impact force when struck by the double-length bars, and the buffer acts as a buffer and limiter.
