Description

Technical Field

[0001] The utility model relates to the technical field of steel strip processing, in particular to a convenient tool changing rack. Background Art

[0002] In the process of processing steel strips, steel strips of different widths or thicknesses need to use matching annular cutters so that the steel strips can be cut smoothly. Therefore, when processing the next different type of steel strip, the annular cutter needs to be replaced on the equipment in advance.

[0003] Commonly used annular cutters are all installed manually, and the annular cutters need to be placed on a specific tool holder (to avoid damage to the annular cutters). During installation, the staff needs to remove the original cutter and then walk to the tool holder of the new cutter. If there are a large number of annular cutters, the staff's moving distance will be longer, which not only increases the labor intensity of the staff, but also consumes more time and reduces the installation efficiency of the annular cutters. Utility Model Content

[0004] In order to improve the installation efficiency of the annular tool, the present application provides a convenient tool changing holder.

[0005] This application provides a convenient tool changer using the following technical solutions:

[0006] A convenient tool changing rack comprises a fixed rack, a pushing rack is movably arranged on the fixed rack, a tool placing rack is installed on the pushing rack, a plurality of placing rods are connected to the tool placing rack, and when an annular tool is replaced, the annular tool is placed on the placing rods.

[0007] By adopting the above technical solution, when replacing the tool, the staff will place the annular tool to be replaced on the placement rod in advance, and then move the push frame to drive the tool holder to move, so that the placement rod moves to the top of the device. The staff will place the tool to be replaced on the placement rod and move the placement rod to the top of the device, thereby shortening the distance between the annular tool to be replaced and the device. At the same time, the original annular tool to be replaced can also be placed on other placement rods, thereby facilitating the staff's operation, reducing the staff's labor intensity, shortening the installation time of the annular tool, and improving the installation efficiency of the annular tool.

[0008] Optionally, the fixed frame is connected to a movable rail, the pushing frame is connected to a fixed block, the fixed block is rotatably connected to a plurality of rollers, and the rollers roll in the movable rail.

[0009] By adopting the above technical solution, the staff realized the movement of the pushing frame through the cooperation of the moving rails and the rollers, ensuring the smooth movement of the pushing frame.

[0010] Optionally, a plurality of fixed cylinders are connected to the pushing frame, a sliding rod is connected to a position on the tool holder corresponding to the fixed cylinder, and a sliding bearing is connected between the sliding rod and the fixed cylinder.

[0011] By adopting the above technical solution, the staff realizes the movement of the tool holder by using the cooperation of the sliding rod, the sliding bearing and the fixed cylinder. The staff can align the placement rod with the placement rod on other tool holders, and by moving the tool holder, the annular tool placed on the placement rod contacts the push rack, and all the annular tools can be removed to other placement rods synchronously, which facilitates the transfer operation of all the annular tools.

[0012] Optionally, a stabilizing component is connected to the pushing frame, and the stabilizing component includes a driving rod, a connecting screw, a limiting rod, a movable plate, a friction block and a clamping piece, the driving rod is rotatably connected to the pushing frame, the connecting screw is connected to the top end of the driving rod and is located between the movable rail and the pushing frame, the limiting rod is connected to the pushing frame and is parallel to the connecting screw, the movable plate is arranged on the connecting screw, the connecting screw and the limiting rod both pass through the movable plate, the connecting screw is threadedly engaged with the movable plate, the limiting rod is slidably engaged with the movable plate, the friction block is connected to the movable plate, and when stabilizing the pushing frame, the friction block presses against the movable rail, the clamping piece is installed on the pushing frame, and the clamping piece is used to stabilize the tool holder.

[0013] By adopting the above technical solution, when stabilizing the pushing frame and the tool holder, the staff moves the placement rod to the top of the equipment, rotates the driving rod, rotates the connecting screw, moves the movable plate, drives the friction block to move, and makes the friction block press against the movable rail to limit the freedom of the pushing frame, and then limits the freedom of the tool holder through the pressing piece, thereby achieving the effect of stabilizing the pushing frame and the tool holder.

[0014] Optionally, the fastening member is a fastening bolt, the fastening member passes through the pushing frame and fastens the tool holder, and the fastening member is threadedly matched with the pushing frame.

[0015] By adopting the above technical solution, when stabilizing the tool holder, the staff rotates the clamping member to move the clamping member until the clamping member is pressed against the tool holder, thereby limiting the freedom of the tool holder.

[0016] Optionally, a plurality of resistance rods are connected to the placement rod, and the resistance rods are parallel to the placement rod.

[0017] By adopting the above technical solution, the annular cutter is placed on the placement rod, and the annular cutter is prone to rubbing against the placement rod, causing impurities such as paint on the placement rod to adhere to the annular cutter, which will affect the installation accuracy of the annular cutter. The staff raised the annular cutter by using the friction rod to leave a gap between the annular cutter and the placement rod, reducing the possibility of the annular cutter touching the placement rod and ensuring the surface finish of the annular cutter.

[0018] Optionally, a wiping assembly is provided at a position on the pushing frame corresponding to the resistance rod, the wiping assembly includes a rotating arc plate and a wiping sponge, one end of the rotating arc plate is rotatably connected to the pushing frame, the wiping sponge is connected to the arc wall of the rotating arc plate, and a limiting assembly for limiting the rotation of the rotating arc plate is provided on the pushing frame. When wiping the resistance rod, the wiping sponge is deformed and fits the surface of the resistance rod.

[0019] By adopting the above technical solution, with long-term use, the surface of the resistance rod may be contaminated with dirt. In order not to affect the installation accuracy of the annular tool, it is necessary to clean the surface of the resistance rod. When cleaning the dirt, the staff flips the rotating arc plate to drive the wiping sponge to rotate, and the wiping sponge is deformed and fits the surface of the resistance rod. Then, the limiting component is used to limit the rotation of the rotating arc plate, and finally the tool holder is pulled to drive the resistance rod to move, so that the wiping sponge rubs against the resistance rod, and the effect of cleaning the dirt on the surface of the resistance rod with the wiping sponge is achieved.

[0020] Optionally, the limiting assembly includes a fixed rod, a moving rod, a connecting block and an ejection spring, the connecting block is connected to the other end of the rotating arc plate, the fixed rod is connected to the pushing frame, the pushing frame is connected to a door-type frame, the moving rod is slidably fitted between the pushing frame and the door-type frame, and is located above the fixed rod, one end of the moving rod is connected to a limiting block, the limiting block abuts against the door-type frame, the moving rod is connected to an ejection block, the ejection spring is sleeved on the moving rod and is located between the door-type frame and the ejection block, the ejection spring is in a compressed state, and when the rotating arc plate is limited from rotating, the connecting block is located between the fixed rod and the moving rod.

[0021] By adopting the above technical solution, when limiting the rotation of the arc plate, the staff presses the moving rod, and the ejection spring is compressed until the connecting block abuts against the fixed rod. The moving rod is released, and the moving rod moves under the action of the ejection spring until the limiting block abuts against the fixed frame. The connecting block is confined between the moving rod and the fixed rod, thereby limiting the freedom of the rotating arc plate and achieving the effect of limiting the rotation of the rotating arc plate.

[0022] In summary, the present application includes at least one of the following beneficial technical effects:

[0023] 1. When replacing a tool, the staff will place the annular tool to be replaced on the placement rod in advance, and then move the push frame to drive the tool holder to move, so that the placement rod moves to the top of the equipment. The staff will place the tool to be replaced on the placement rod and move the placement rod to the top of the equipment, thereby shortening the distance between the annular tool to be replaced and the equipment. At the same time, the original annular tool to be replaced can also be placed on other placement rods, which facilitates the staff's operation, reduces the staff's labor intensity, shortens the installation time of the annular tool, and improves the installation efficiency of the annular tool;

[0024] 2. When cleaning dirt, the staff turns the rotating arc plate to drive the wiping sponge to rotate, and the wiping sponge is deformed and fits the surface of the resistance rod. Then the limiting component is used to limit the rotation of the rotating arc plate, and finally the knife holder is pulled to drive the resistance rod to move, so that the wiping sponge rubs against the resistance rod, and the wiping sponge cleans the dirt on the surface of the resistance rod;

[0025] 3. When limiting the rotation of the arc plate, the staff presses the moving rod, and the ejector spring is compressed until the connecting block contacts the fixed rod. The moving rod is released, and the moving rod moves under the action of the ejector spring until the limiting block contacts the fixed frame. The connecting block is restricted between the moving rod and the fixed rod, thereby limiting the freedom of the rotating arc plate and achieving the effect of limiting the rotation of the rotating arc plate.
