Description

Technical Field

[0001] The utility model relates to an auxiliary mechanism for casting cutting equipment, in particular to a cutting execution mechanism for casting cutting equipment. Background Art

[0002] Existing container corner fittings are typically manufactured using sand casting, with the finished casting typically containing four corner fittings. Currently, the primary method for separating the cast corner fittings is to use cutting equipment to separate the corner fittings after the sand shell cools naturally and the sand falls out.

[0003] Existing equipment for cutting container corner castings generally uses thermal cutting methods such as flame, plasma, and laser, or cold cutting methods such as band saws, circular saws, and milling cutters. This results in low cutting efficiency and high costs. To address this issue, some manufacturers have begun to gradually experiment with setting pointed grooves in the casting and guide areas of the container corner workpieces to form cutting edges. A hydraulically driven expansion mechanism is then used to directly apply force to the poured container corner workpieces, causing a direct fracture at the cutting edge, thereby quickly separating and cutting the container corner castings. While this effectively improves cutting efficiency and reduces cutting costs, it can easily cause significant mechanical damage to the workpiece surface, leading to significant deformation of the workpiece surface, which can cause problems in subsequent end face milling.

[0004] Therefore, the research purpose of this utility model is to design a cutting actuator for casting cutting equipment that can not only complete the separation and cutting of the cast container corner parts at a lower cost, but also ensure that no excessive mechanical damage is caused to the workpiece surface during the separation and cutting process. Summary of the Invention

[0005] In view of the technical problems existing in the above-mentioned prior art, the present invention provides a cutting actuator for a casting cutting device, which can effectively solve the technical problems existing in the above-mentioned prior art.

[0006] The technical solution of the utility model is:

[0007] A cutting actuator for a casting cutting device, comprising:

[0008] a set of jacking teeth, laterally movably mounted on the front side of the corresponding housing, wherein the front end of the jacking teeth extends to the outside of the housing;

[0009] a cutting rod, longitudinally movably mounted in the housing, wherein the front end of the cutting rod is pointed and located between the inner ends of a group of the tightening teeth;

[0010] The telescopic drive mechanism is installed on the rear side of the casing and is used to drive the cutting rod to extend and retract. The cutting rod extends forward to between a group of the clamping teeth. A group of the clamping teeth are pushed outward and clamped at the connection of the workpiece under the pushing drive of the cutting rod. After the cutting rod extends forward to the outside of the group of the clamping teeth, the connection of the workpiece is cut.

[0011] The telescopic driving mechanism adopts a driving oil cylinder, and the rear end of the cutting rod is fixedly connected to the piston rod end of the driving oil cylinder through a corresponding coil spring.

[0012] An ultrasonic transducer sleeved in the coil spring is fixedly mounted on the rear end portion of the cutting rod, and the ultrasonic transducer is connected to an external ultrasonic generator.

[0013] When the compression amount of the coil spring reaches L1, the cutting rod pushes away the tightening tooth; when the compression amount of the coil spring reaches L2, the ultrasonic transducer is triggered, and under ultrasonic vibration, the pointed end of the cutting rod ultrasonically cuts the joint of the workpiece.

[0014] A group of corresponding tightening balls with ends located on the outside of the tightening teeth are respectively and rollingly mounted on the inner end surfaces of the tightening teeth. The tightening balls on different tightening teeth are arranged alternately. The tightening teeth are respectively provided with embedding grooves corresponding to the tightening balls. After the cutting rod pushes open the tightening teeth, it forms a rolling contact with the tightening balls.

[0015] Guide shafts that pass through the jacking gear piece laterally are fixedly connected to both sides of the front end of the housing. Compression springs that are extruded and installed between the housing and the jacking gear piece are fixedly sleeved on the guide shafts.

[0016] The inner ends of the tightening teeth are respectively fixed with corresponding clamping plates, and guide grooves adapted to the clamping plates are provided on both sides of the housing, and the clamping plates can be movably installed in the guide grooves.

[0017] The outer ends of the tightening teeth are respectively arranged in an inclined shape, and the outer ends of the tightening teeth are respectively provided with corresponding anti-slip grooves.

[0018] Advantages of this utility model:

[0019] 1) This utility model uses a telescopic drive mechanism to directly drive the cutting rod forward. During this process, a set of clamping teeth are first pushed outward laterally to clamp onto the workpiece, thereby securing it laterally. The cutting rod then extends further, directly applying force to sever the workpiece joint. This method not only achieves the separation and severing of cast container corner parts at a low cost, but also ensures that the separation and severing process does not cause excessive mechanical damage to the workpiece surface.

[0020] 2) To improve the cutting effect and efficiency, the present invention further connects the cutting rod to the piston rod end of the driving cylinder through a coil spring, and an ultrasonic transducer is fixedly installed at the rear end of the cutting rod. When the compression of the coil spring reaches L1, the thrust of the coil spring on the cutting rod is sufficient to drive the clamping teeth to move laterally outward, so as to drive a group of clamping teeth to press against the side wall of the workpiece. At this time, lateral fixation can be formed to fix the clamping teeth between the intervals of the workpiece, and the clamping teeth only play a limiting role. Before the cutting rod moves forward to press against the joint of the workpiece, the piston rod of the driving cylinder continues to extend, and the coil spring is further compressed. When the compression of the coil spring reaches L2, that is, when the cutting rod abuts against the joint of the workpiece and exerts sufficient pressure on the joint of the workpiece, the ultrasonic transducer is triggered, so that under the action of high-frequency vibration and sufficient pressure, the pointed end of the cutting rod can smoothly cut the joint of the workpiece. This can greatly improve the cutting effect and efficiency, so as to further complete the separation and cutting of the cast container corner parts at a lower cost, and ensure that no excessive mechanical damage is caused to the workpiece surface during the separation and cutting process.

[0021] 3) The inner end surfaces of a group of tightening teeth of the utility model are respectively rollingly mounted with tightening balls whose ends are located on the outside of the tightening teeth. The tightening balls located on different tightening teeth are arranged alternately, and the tightening teeth are respectively provided with embedding grooves corresponding to the tightening balls to prevent the setting of the tightening balls from affecting the closing setting of a group of tightening teeth; and under the action of the tightening balls, the cutting rod can form rolling friction with the tightening teeth when it pushes open a group of tightening teeth and moves outward, thereby reducing component wear and reducing the influence of friction on elastic force, so as to ensure the practical effect of the utility model.

[0022] 4) The present invention can ensure that the tightening tooth piece still has sufficient stability in an ultrasonic vibration environment through the cooperation and limitation of the guide shaft and the clamping plate, thereby further ensuring the practical effect of the present invention.

[0024] Figure 2 This is a diagram of the usage state of the utility model.

[0025] In the accompanying drawings: a tightening gear 1, a housing 2, a cutting rod 3, a telescopic drive mechanism 4, a coil spring 5, an ultrasonic transducer 6, a tightening ball 7, a guide shaft 8, a compression spring 9, a clamping plate 10, and an anti-slip groove 11. DETAILED DESCRIPTION

[0026] In order to facilitate understanding by those skilled in the art, the structure of the present invention is further described in detail with reference to the following embodiments and accompanying drawings:

[0027] refer to Figure 1-2 , a cutting actuator for a casting cutting device, comprising:

[0028] A set of jacking teeth 1 is laterally movably mounted on the front side of the corresponding housing 2, and the front end of the jacking teeth 1 extends to the outside of the housing 2;

[0029] A cutting rod 3 is longitudinally movably mounted in the housing 2, wherein the front end of the cutting rod 3 is pointed and located between the inner ends of a group of the tightening teeth 1;

[0030] The telescopic drive mechanism 4 is installed on the rear side of the casing 2 and is used to drive the cutting rod 3 to extend and retract. The cutting rod 3 extends forward between a group of the clamping teeth 1. A group of the clamping teeth are pushed outward and clamped at the connection of the workpiece under the pushing drive of the cutting rod 3. After the cutting rod 3 extends forward to the outside of a group of the clamping teeth 1, the connection of the workpiece is cut.

[0031] The present invention uses a telescopic drive mechanism 4 to directly drive the cutting rod 3 forward. During this process, a set of clamping teeth 1 are first pushed outward laterally to clamp onto the workpiece, thereby securing it laterally. The cutting rod 3 then extends further, directly applying force to sever the workpiece joint. This allows for the cost-effective separation and severing of cast container corner pieces while ensuring that the separation and severing process does not inflict excessive mechanical damage to the workpiece surface.

[0032] The telescopic drive mechanism 4 uses a drive cylinder, and the rear end of the cutting rod 3 is fixedly connected to the piston rod end of the drive cylinder via a corresponding coil spring 5. The rear end of the cutting rod 3 is fixedly mounted with an ultrasonic transducer 6 sleeved within the coil spring 5, and the ultrasonic transducer 6 is connected to an external ultrasonic generator.

[0033] When the compression amount of the coil spring 5 reaches L1, the cutting rod 3 pushes away the tightening tooth 1; when the compression amount of the coil spring 5 reaches L2, the ultrasonic transducer 6 is triggered, and under ultrasonic vibration, the pointed end of the cutting rod 3 ultrasonically cuts the joint of the workpiece.

[0034] When the compression amount of the coil spring 5 reaches L1, the pushing force of the coil spring 5 on the cutting rod 3 is sufficient to drive the clamping tooth 1 to move laterally outward, so as to drive a group of clamping teeth 1 to press against the side wall of the workpiece. At this time, lateral fixation can be formed to fix the clamping tooth 1 between the intervals of the workpiece, and the clamping tooth 1 only plays a limiting role; before the cutting rod 3 moves forward to press against the connection point of the workpiece, the piston rod of the driving cylinder continues to extend, and the coil spring 5 is further compressed. When the compression amount of the coil spring 5 reaches L2, that is, the cutting rod 3 abuts against the connection point of the workpiece and has sufficient pressure on the connection point of the workpiece, the ultrasonic transducer 6 is triggered, so that under the action of high-frequency vibration and sufficient pressure, the pointed end of the cutting rod 3 can smoothly cut off the connection point of the workpiece.

[0035] The inner end surfaces of a group of the tightening teeth 1 are respectively and rollingly mounted with a plurality of corresponding tightening balls 7, the ends of which are located outside the tightening teeth 1. The tightening balls 7 on different tightening teeth 1 are arranged in a staggered manner. The tightening teeth 1 are respectively provided with mounting grooves corresponding to the tightening balls 7. After the cutting rod 3 pushes away the tightening teeth 1, it forms rolling contact with the tightening balls 7. Under the action of the tightening balls 7, the cutting rod 3 can form rolling friction with the tightening teeth 1 when pushing away a group of the tightening teeth 1 and moving outward, thereby reducing component wear and reducing the influence of friction on elastic force, so as to ensure the practical effect of the present invention.

[0036] Guide shafts 8 are fixedly attached to both sides of the front end of the housing 2, extending transversely through the jacking gear 1. A compression spring 9 is fixedly sleeved on each guide shaft 8 and extruded between the housing 2 and the jacking gear 1. Corresponding clamping plates 10 are fixedly attached to the inner ends of the jacking gear 1. Guide grooves matching the clamping plates 10 are provided on both sides of the housing 2, into which the clamping plates 10 can be movably mounted. The coordinated positioning of the guide shafts 8 and the clamping plates 10 ensures that the jacking gear 1 maintains sufficient stability even in ultrasonic vibration environments, further ensuring the practical effects of the present invention.

[0037] The outer ends of the tightening teeth 1 are respectively arranged in an inclined shape, and the outer ends of the tightening teeth 1 are respectively provided with corresponding anti-slip grooves 11.

[0038] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as within the scope of protection of the present invention.
