Description

Technical Field

[0001] This utility model relates to the technical field of steel strip processing equipment, and in particular to an automatic cutting device for hot-dip galvanized steel strip. Background Technology

[0002] Hot-dip galvanized steel strip is a material formed by galvanizing the surface of steel strip. This galvanized layer has self-healing properties, meaning that after the steel strip surface is scratched or worn, the zinc layer will re-precipitate and form a new zinc layer, thus protecting the steel strip. In the production process of hot-dip galvanized steel strip, continuous steel strips need to be cut to specific length requirements to meet the needs of subsequent processing or use. Existing automatic cutting devices for hot-dip galvanized steel strips experience bouncing problems at the cut points due to the rigidity of the hot-dip galvanized steel strip itself, which affects the connection and cutting operation of the hot-dip galvanized steel strip. Furthermore, the hot-dip galvanized steel strip may bend during transportation, affecting the smoothness of the transport. Utility Model Content

[0003] The purpose of this utility model is to provide an automatic cutting device for hot-dip galvanized steel strip, in order to solve the problems mentioned in the background art. When cutting hot-dip galvanized steel strip, due to the rigidity of the hot-dip galvanized steel strip itself, the cut point of the hot-dip galvanized steel strip will bounce, which will easily affect the connection and cutting operation of the hot-dip galvanized steel strip. In addition, the hot-dip galvanized steel strip will bend during transportation, which will affect the smoothness of transportation.

[0004] The purpose and effectiveness of this utility model's automatic hot-dip galvanized steel strip cutting device are achieved through the following specific technical means:

[0005] An automatic cutting device for hot-dip galvanized steel strip includes a cutting base; a double-headed hydraulic cylinder is fixedly installed in the middle of the left and right side walls of the cutting base; upper and lower parallel plates are fixedly connected to the upper and lower ends of the double-headed hydraulic cylinder; fixed clamping plates are slidably connected to the front and rear side walls of the upper and lower parallel plates; and a magnetic suction conveying roller is rotatably connected to the top end face of the cutting base.

[0006] Furthermore, a through groove is provided in the middle of the top end face of the cutting base. The bottom left and right outer walls of the through groove are concave upwards. Six magnetic conveying rollers are rotatably connected to the front and rear ends of the cutting base at the top of the through groove. Upper and lower connecting plates are slidably connected to the bottom of the through groove.

[0007] Furthermore, a top conveying roller is rotatably connected to the left and right inner walls of the cutting base above the magnetic conveying roller. A gap is formed between the bottom of the top conveying roller and the top of the magnetic conveying roller. An elongated observation groove is provided in the left and right side walls of the cutting base between the magnetic conveying roller and the top conveying roller.

[0008] Furthermore, two upper and lower combined plates are symmetrically provided, and a cutting blade is fixedly connected to the middle of the side wall of the two opposite upper and lower combined plates. A rectangular guide groove is opened in the middle of the front and rear side walls at the connection between the cutting blade and the upper and lower combined plates. Four guide holes are opened in a rectangular array in the upper and lower combined plates.

[0009] Furthermore, the fixed clamp is rectangular in shape, and two guide slide rods are symmetrically fixedly installed on the opposite side walls of the fixed clamp and the upper and lower combined plates. The guide slide rods are slidably connected in the guide slide holes of the upper and lower combined plates, and a return spring is sleeved on the guide slide rod between the opposite side walls of the fixed clamp and the upper and lower combined plates.

[0010] Furthermore, the fixing clamp is attached to the side wall of the cutting blade plate of the upper and lower combined plates and is provided with a guide slider. The guide slider is slidably connected in the guide grooves opened on the upper and lower combined plates on the front and rear sides of the cutting blade plate.

[0011] This utility model provides an automatic cutting device for hot-dip galvanized steel strip, which has the following advantages:

[0012] 1. By opening a through-slide groove in the middle of the top end face of the cutting base, and making the top of the left and right outer side walls of the bottom of the through-slide groove concave, the upper and lower merging plates at the bottom of the through-slide groove can slide under the control of the double-headed hydraulic cylinder, thus avoiding affecting the cutting operation of the upper and lower merging plates. In addition, the magnetic suction conveying rollers rotatably connected in the top end face of the cutting base on the front and rear sides of the top of the through-slide groove can better hold the hot-dip galvanized steel strip firmly to prevent the hot-dip galvanized steel strip from bouncing. The cooperation of the magnetic suction conveying roller and the top conveying pressure roller forms a conveying space to guide the hot-dip galvanized steel strip and prevent the hot-dip galvanized steel strip from being deviated during conveying. In addition, long strip-shaped observation grooves are opened in the left and right side walls of the cutting base to observe the hot-dip galvanized steel strip passing between the magnetic suction conveying roller and the top conveying pressure roller.

[0013] 2. During the process of controlling the two upper and lower parallel plates to approach each other through the double-headed hydraulic cylinder, the fixed clamps that are slidably connected on the front and rear side walls of the two upper and lower parallel plates will first contact the hot-dip galvanized steel strip. As the two upper and lower parallel plates continue to approach, the fixed clamps are firmly attached to the hot-dip galvanized steel strip under the action of the return spring. When the upper and lower parallel plates are cut, the fixed clamps stabilize the hot-dip galvanized steel strip and prevent the hot-dip galvanized steel strip from bouncing. This improves the cutting safety of the hot-dip galvanized steel strip. In addition, the guide slide rod and guide slider on the fixed clamp will protrude from the upper and lower parallel plates to release pressure. Attached Figure Description

[0023] Example 1:

[0024] As attached Figure 1 To be continued Figure 6 As shown:

[0025] This utility model provides an automatic cutting device for hot-dip galvanized steel strip, comprising: a cutting base 1; a double-headed hydraulic cylinder 4 fixedly installed in the middle of the left and right side walls of the cutting base 1, upper and lower connecting plates 5 fixedly connected to the upper and lower ends of the double-headed hydraulic cylinder 4, and fixed clamping plates 6 slidably connected to the front and rear side walls of the upper and lower connecting plates 5; a magnetic suction conveying roller 2 rotatably connected to the top end face of the cutting base 1; a through groove 101 opened in the middle of the top end face of the cutting base 1, the bottom left and right outer side walls of the through groove 101 being concave upwards; and six magnetic suction conveying rollers rotatably connected to the front and rear sides of the top of the through groove 101 on the end face of the cutting base 1. The roller 2 and the bottom of the through chute 101 are slidably connected to the upper and lower parallel plates 5. Specifically, by opening the through chute 101 in the middle of the top end face of the cutting base 1, and making the top of the left and right outer side walls of the bottom of the through chute 101 concave, the upper and lower parallel plates 5 at the bottom of the through chute 101 can slide under the control of the double-headed hydraulic cylinder 4, avoiding affecting the cutting operation of the upper and lower parallel plates 5. In addition, the magnetic suction conveying roller 2, which is rotatably connected to the top end face of the cutting base 1 on the front and rear sides of the top of the through chute 101, can better hold the hot-dip galvanized steel strip firmly to prevent the hot-dip galvanized steel strip from bouncing and ensure the stability of the hot-dip galvanized steel strip conveying.

[0026] Among them, the cutting base 1 above the magnetic conveying roller 2 is rotatably connected to the left and right inner walls of the cutting base 1. A gap is formed between the bottom of the top conveying roller 3 and the top of the magnetic conveying roller 2. The left and right side walls of the cutting base 1 between the magnetic conveying roller 2 and the top conveying roller 3 are provided with long strip-shaped observation grooves 102. Specifically, the magnetic conveying roller 2 and the top conveying roller 3 cooperate to form a conveying space to guide the hot-dip galvanized steel strip and prevent the hot-dip galvanized steel strip from being deviated during conveying. The long strip-shaped observation grooves 102 are provided in the left and right side walls of the cutting base 1 to observe the hot-dip galvanized steel strip passing between the magnetic conveying roller 2 and the top conveying roller 3.

[0027] Two upper and lower merging plates 5 are symmetrically arranged. A cutting blade 501 is fixedly connected to the middle of the side wall of the two opposite upper and lower merging plates 5. A rectangular guide groove 503 is opened in the middle of the front and rear side walls at the connection between the cutting blade 501 and the upper and lower merging plates 5. Four guide sliding holes 502 are opened in a rectangular array in the upper and lower merging plates 5. Specifically, by controlling the upper and lower ends of the double-headed hydraulic cylinder 4, the two upper and lower merging plates 5 can be brought closer to each other, so that the cutting blade 501 on the opposite side wall of the two upper and lower merging plates 5 can realize the automatic cutting operation of hot-dip galvanized steel strip.

[0028] The fixed clamping plate 6 is rectangular in shape. Two guide slide rods 601 are symmetrically fixed on the opposite side walls of the fixed clamping plate 6 and the upper and lower combined plates 5. The guide slide rods 601 are slidably connected in the guide slide holes 502 of the upper and lower combined plates 5. A return spring 7 is sleeved on the guide slide rods 601 between the opposite side walls of the fixed clamping plate 6 and the upper and lower combined plates 5. A guide slider 602 is provided on the side wall of the cutting blade plate 501 of the fixed clamping plate 6 and the upper and lower combined plates 5. The guide slider 602 is slidably connected in the guide slide grooves 503 opened on the front and rear sides of the cutting blade plate 5 and the upper and lower combined plates 5. Specifically, it is used by a double-headed hydraulic cylinder. 4. During the process of controlling the two upper and lower parallel plates 5 to approach each other, the fixed clamping plates 6 that are slidably connected on the front and rear side walls of the two upper and lower parallel plates 5 will first contact the hot-dip galvanized steel strip. As the two upper and lower parallel plates 5 continue to approach each other, the fixed clamping plates 6 are firmly attached to the hot-dip galvanized steel strip under the action of the return spring 7. When the upper and lower parallel plates 5 are cut, the fixed clamping plates 6 stabilize the hot-dip galvanized steel strip and prevent the hot-dip galvanized steel strip from bouncing. This improves the cutting safety of the hot-dip galvanized steel strip. In addition, the guide slide rod 601 and guide slider 602 on the fixed clamping plates 6 will protrude from the upper and lower parallel plates 5 to release pressure.

[0029] The specific usage and function of this embodiment are as follows:

[0030] When using this automatic cutting device for hot-dip galvanized steel strip, a through groove 101 is opened in the middle of the top end face of the cutting base 1, and the top of the left and right outer side walls of the bottom of the through groove 101 is concave. This facilitates the sliding of the upper and lower merging plates 5 at the bottom of the through groove 101 under the control of the double-headed hydraulic cylinder 4, avoiding any impact on the cutting operation of the upper and lower merging plates 5. Furthermore, the magnetically attached conveying rollers 2, which are rotatably connected in the top end face of the cutting base 1 on both the front and rear sides of the top of the through groove 101, can better hold the hot-dip galvanized steel strip firmly, preventing it from bouncing. The cooperation of the magnetically attached conveying rollers 2 and the top conveying pressure roller 3 forms a conveying space to guide the hot-dip galvanized steel strip and prevent conveying deviation. Long, narrow observation grooves 102 are opened in the left and right side walls of the cutting base 1 to observe the hot-dip galvanized steel strip passing between the magnetically attached conveying rollers 2 and the top conveying pressure roller 3. By controlling the two upper and lower parallel plates 5 through the upper and lower ends of the double-headed hydraulic cylinder 4, the two upper and lower parallel plates 5 can be brought closer together. Thus, the cutting blades 501 on the opposite side walls of the two upper and lower parallel plates 5 realize the automatic cutting operation of the hot-dip galvanized steel strip. During the process of the two upper and lower parallel plates 5 being brought closer together by the double-headed hydraulic cylinder 4, the fixed clamping plates 6 that are slidably connected on the front and rear side walls of the two upper and lower parallel plates 5 will first contact the hot-dip galvanized steel strip. As the two upper and lower parallel plates 5 continue to move closer, the fixed clamping plates 6 are firmly attached to the hot-dip galvanized steel strip under the action of the return spring 7. When the upper and lower parallel plates 5 are cutting, the fixed clamping plates 6 keep the hot-dip galvanized steel strip stable and prevent the hot-dip galvanized steel strip from bouncing. This improves the cutting safety of the hot-dip galvanized steel strip. In addition, the guide slide rod 601 and guide slider 602 on the fixed clamping plates 6 will protrude from the upper and lower parallel plates 5 to release pressure.

[0031] Example 2:

[0032] By installing two sets of top conveying rollers 3 on the front and rear sides of the top of the cutting base 1 in a frame, the distance between the top conveying rollers 3 and the magnetic conveying rollers 2 can be changed by adjusting the position of the frame on the top of the cutting base 1. This allows for better adjustment based on the thickness of the hot-dip galvanized steel strip and improves the conveying control of the hot-dip galvanized steel strip.
