Abstract
Description
Technical Field
[0001] This invention belongs to the field of heat-shrink tool holder technology and relates to a device for removing a broken tool from a heat-shrink tool holder. Background Technology
[0002] Currently, during machining processes, heat-shrink tool holders are prone to tool breakage, resulting in broken tools remaining inside the heat-shrink tool holder. After heating, the inner bore of the heat-shrink tool holder shrinks, causing the broken tool to adhere more tightly to the holder, making it difficult to hold with traditional tools. Existing removal devices rely on external striking or forceful pulling. Traditional methods for removing broken tools from heat-shrink tool holders primarily use mechanical pulling, which not only easily leads to tool holder deformation or secondary breakage of the broken tool but also damages the precision of the tool holder's inner bore. Furthermore, the lack of specialized tools for the characteristics of heat-shrink tool holders results in low operational efficiency. Therefore, we have designed a device for removing broken tools from heat-shrink tool holders to solve the aforementioned technical problems. Summary of the Invention
[0003] The purpose of this invention is to provide a device for removing broken blades from heat-shrink tool holders, so as to solve the problems mentioned in the background art.
[0004] To achieve the above objectives, the present invention provides the following technical solution:
[0005] A device for removing a broken knife from a heat-shrinkable knife handle includes a heat-shrinkable body and a heat-shrinkable knife handle. A column is fixedly provided on one side of the top of the heat-shrinkable body, and a liftable magnetic induction heating coil is provided on the side of the column. An ejector base is detachably fixed on the other side of the top of the heat-shrinkable body, and an ejector rod is fixedly provided at the top of the ejector base. An insertion hole is provided at the bottom of the heat-shrinkable knife handle, and the top of the ejector rod extends into the interior of the insertion hole.
[0006] In the above-mentioned device for removing a broken knife from a heat-shrink knife handle, the broken knife is fixedly provided at the top of the heat-shrink knife handle, and the bottom end of the broken knife is in contact with the top end of the ejector rod.
[0007] In the above-mentioned device for removing a broken knife from a heat-shrinkable knife holder, an electric slide rail is fixedly installed on the side of the column, and a slide block is slidably connected to the surface of the electric slide rail. The slide block is fixedly connected to the side of the magnetic induction heating coil.
[0008] In the above-mentioned device for removing a broken knife from a heat-shrinkable knife handle, a nesting hole is provided at the center of the magnetic induction heating coil, and the nesting hole is on the same straight line as the axis of the heat-shrinkable knife handle.
[0009] In the above-mentioned device for removing a broken knife from a heat-shrinkable knife handle, a lifting control handle is fixedly provided on the front side of the magnetic induction heating coil.
[0010] In the above-mentioned device for removing a broken knife from a heat-shrink knife holder, the size of the end face of the ejector rod is smaller than the inner diameter of the insertion hole.

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0017] Please see Figure 1-2 This invention provides a technical solution for a device for removing a broken knife from a heat-shrink knife holder:
[0018] according to Figure 1-2 As shown, a device for removing a broken knife from a heat-shrinkable knife handle includes a heat-shrinkable body 1 and a heat-shrinkable knife handle 4. A column 7 is fixedly provided on one side of the top of the heat-shrinkable body 1, and a liftable magnetic induction heating coil 5 is provided on the side of the column 7. An ejector base 2 is detachably fixed on the other side of the top of the heat-shrinkable body 1. An ejector rod 3 is fixedly provided at the top of the ejector base 2. An insertion hole is provided at the bottom of the heat-shrinkable knife handle 4, and the top of the ejector rod 3 extends into the interior of the insertion hole.
[0019] Specifically, the present invention provides a device for removing a broken knife from a heat-shrinkable knife holder. Through the cooperation of the heat-shrinkable body 1 and the ejector, the broken knife 9 can be removed from the heat-shrinkable knife holder 4 without damage, solving the problem of damage to the inner hole precision of the knife holder caused by the traditional mechanical pulling method.
[0020] according to Figure 1and Figure 2 As shown, the present invention provides a device for removing a broken knife from a heat-shrink knife handle. A broken knife 9 is fixedly provided on the top of the heat-shrink knife handle 4, and the bottom end of the broken knife 9 is in contact with the top end of the ejector rod 3.
[0021] Specifically, the heated and expanded broken knife 9 can be ejected by the ejector rod 3.
[0022] An electric slide rail 8 is fixedly installed on the side of the column 7. A slide block is slidably connected to the surface of the electric slide rail 8. The slide block is fixedly connected to the side of the magnetic induction heating coil 5.
[0023] Specifically, the magnetic induction heating coil 5 is raised and lowered by the electric slide rail 8.
[0024] A nesting hole is provided at the center of the magnetic induction heating coil 5, and the nesting hole and the axis of the heat shrink handle 4 are on the same straight line.
[0025] Specifically, the magnetic induction heating coil 5 is nested with the heat shrink handle 4.
[0026] A lifting control handle 6 is fixedly installed on the front of the magnetic induction heating coil 5.
[0027] The size of the end face of the ejector rod 3 is smaller than the inner diameter of the insertion hole. Specifically, the ejector rod 3 is nested with the bottom end of the heat shrink tool holder 4.
[0028] Working Principle: This invention discloses a device for removing broken knives from heat-shrink knife handles. When using this device, first connect the power supply, fix the ejector base 2 to the top of the heat-shrink machine body 1, then insert the bottom end of the heat-shrink knife handle 4 into the ejector rod 3, and then open the electric slide rail 8 through the lifting control handle 6. The electric slide rail 8 drives the magnetic induction heating coil 5 to move down, so that the magnetic induction heating coil 5 and the broken knife 9 of the heat-shrink knife handle 4 are aligned and nested, and the axis of the magnetic induction heating coil 5 and the heat-shrink knife handle 4 are on the same straight line. Then, the magnetic induction heating coil 5 is used for heating. After the heat-shrink knife handle 4 is heated, the broken knife 9 will be naturally ejected due to thermal expansion and contraction and the weight of the heat-shrink knife handle 4.
