Description

Technical Field

[0001] This utility model relates to the technical field of wooden molds, and in particular to a cutting mechanism for steel plates used in wooden molds. Background Technology

[0002] In casting production, the models used for molding and core making are called wooden patterns, also known as wooden molds. The outer frame of the wooden pattern requires steel, and the steel plate needs to be cut using a flame cutter. A flame cutter is a cutting device that uses fuel gas mixed with oxygen or gasoline mixed with oxygen to cut metal materials. The tracks of the flame cutting mechanism are mostly placed parallel to a flat plate. These tracks are prone to shifting. Part of the steel plate lies flat on the plate (this is the part to be cut), while the majority of the steel plate is outside the plate, requiring additional support blocks. The flame cutter moves along the tracks to cut the steel plate. Since the flat plate cannot fully support the steel plate, additional support blocks are needed each time. Summary of the Invention

[0003] In view of this, the purpose of this utility model is to overcome the shortcomings of the prior art and provide a cutting mechanism for wooden mold steel plates.

[0004] This utility model provides a cutting mechanism for a wooden formwork steel plate, including a support frame 1. A T-shaped guide bar 2 is longitudinally arranged on the support frame 1. A flame cutter 4 is rotatably arranged on the guide bar 2. A drive assembly for driving the flame cutter 4 is provided on the guide bar 2 and the flame cutter 4. A storage groove is symmetrically opened on the support frame 1. An extension plate 5 flush with the upper end surface of the support frame 1 is rotatably arranged at the storage groove via a rotating shaft.

[0005] Furthermore, the drive assembly includes a rack 3 arranged longitudinally on the guide bar 2, and the flame cutter 4 is provided with a gear driven by a motor and meshing with the rack 3.

[0006] Furthermore, the bottom of the extension plate 5 is provided with a notch, and a support leg 6 is hinged to the notch.

[0007] Furthermore, two circular holes are provided on the storage groove, and the circular holes are distributed circumferentially on the rear and left sides along the axis of the rotating shaft. A countersunk hole is provided on the extension plate 5, and a pin 7 is inserted into the countersunk hole and the circular hole.

[0008] Furthermore, limit blocks 8 are installed on both the front and rear sides of the guide strip 2.

[0009] Furthermore, the support frame 1 is rectangular.

[0010] The advantages of this invention are as follows: A support frame supports the steel plate, and a retractable and deployable extension plate supports excessively wide steel plates; rollers around the flame cutter roll along a T-shaped guide rail; a storage slot accommodates the extension plate, reducing floor space; if an excessively wide steel plate is placed on the support frame, it will tip over, but rotating the extension plate unfolds it, allowing it to be perpendicular to the support frame for support; a motor drives gears to rotate, and the gears meshing with the rack move the flame cutter back and forth along the guide rail, supporting the flame cutter against the support. The steel plates on the frame are cut in a straight line; the legs can be stored in the notch, and the legs fit snugly against the bottom of the storage slot. When the extension plate is unfolded, the legs can be unfolded and set perpendicular to the extension plate, with the top of the legs abutting against the extension plate; when the extension plate is stored in the storage slot, the pin is inserted into the countersunk hole and the round hole on the rear side to fix the extension plate. When the extension plate is unfolded and set perpendicular to the support frame, the pin is inserted into the countersunk hole and the round hole on the left side to fix the extension plate, thereby preventing the extension plate from shaking; the limit block can restrict the flame cutter to prevent the flame cutter from rolling out of the guide bar.

[0015] The present invention will now be described in detail with reference to the accompanying drawings.

[0016] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model.

[0017] See Figures 1 to 4This utility model provides a cutting mechanism for steel plates in wooden molds, which includes a support frame 1. The support frame 1 is rectangular, and the cutting point of the flame cutter is located in the hollow part of the support frame, so that the flame cutter will not cut the support frame. A T-shaped guide bar 2 is arranged longitudinally on the support frame 1, and a flame cutter 4 is rolled on the guide bar 2. Rollers around the flame cutter roll along the guide bar. A drive component is provided on the guide bar 2 and the flame cutter 4 to drive the flame cutter 4 to move. The drive component can drive the flame cutter to roll back and forth along the guide bar, thereby cutting the steel plate on the support frame in a straight line. The support frame 1 has symmetrically opened storage slots at the front and back. The storage slots can be used to store extension plates, thereby reducing the floor space. An extension plate 5 is rotatably arranged in the storage slots and is flush with the upper end face of the support frame 1. Since the width of the steel plate is too large, the steel plate will tip over when placed on the support frame. The extension plate is rotated to unfold the extension plate. The unfolded extension plate can be set perpendicular to the support frame to support the steel plate.

[0018] The drive assembly includes a rack 3 longitudinally mounted on the guide bar 2, and a gear on the flame cutter 4 that is driven by a motor and meshes with the rack 3. The motor drives the gear to rotate, and the gear meshing with the rack can move the flame cutter back and forth along the guide bar, allowing the flame cutter to perform a straight cut on the steel plate on the support frame.

[0019] The bottom of the extension plate 5 has a notch, and a support leg 6 is hinged to the notch. When the extension plate is stored in the storage slot, the support leg can be stored in the notch, and the support leg fits against the bottom of the storage slot. When the extension plate is unfolded, the support leg can be unfolded and set perpendicular to the extension plate, with the top of the support leg abutting against the extension plate, and the support leg supports the extension plate to support the steel plate.

[0020] See Figure 3 , Figure 4 Two round holes are provided on the storage slot, and the round holes are distributed circumferentially along the axis of the rotating shaft on the rear and left sides. The extension plate 5 has a countersunk hole, and a pin 7 is inserted into the countersunk hole and the round hole. When the extension plate is stored in the storage slot, the pin is inserted into the countersunk hole and the round hole on the rear side to fix the extension plate. When the extension plate is unfolded and set perpendicular to the support frame, the pin is inserted into the countersunk hole and the round hole on the left side to fix the extension plate, thereby preventing the extension plate from shaking.

[0021] Limit blocks 8 are installed on both the front and rear sides of the guide bar 2. The limit blocks can restrict the flame cutter to prevent it from rolling off the guide bar.

[0022] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
