Description

Technical Field

[0001] The present invention relates to the technical field of casting cutting equipment, and in particular to a casting cutting equipment for processing container corner fittings, which is mainly used for cutting the container corner fittings after casting. Background Art

[0002] Container corner fittings are also called box corners and lifting corners. They are mainly used at the corners of containers and play a key role in the lifting, handling, fixing, stacking and fastening of containers. Existing container corner fittings are generally processed by sand casting. After the casting is completed, the casting generally contains four container corner fittings.

[0003] At present, the main method for separating the corner fittings of containers after casting is to use cutting equipment to cut and separate the corner fittings of containers after the sand shell cools naturally and the sand falls off. Existing cutting equipment generally adopts thermal cutting methods such as flame, plasma, laser, etc., or cold cutting cutting equipment such as band saw, circular saw, milling cutter, etc. It has the problems of low cutting efficiency and high cost. In order to solve this problem, some manufacturers have begun to gradually try to set pointed grooves in the pouring guide area of ​​the corner fittings of containers to form a cutting edge, and then directly drive the corner fittings of the container after pouring through the expansion method, so that the cutting edge is directly broken, thereby quickly cutting off the corner fittings of the container. Although this effectively improves the cutting efficiency and reduces the cutting cost, it is easy to cause greater mechanical damage to the surface of the workpiece, which is easy to cause obvious deformation of the surface of the workpiece, thus causing trouble for the subsequent end face milling process.

[0004] Therefore, the research purpose of the present invention is to design a casting cutting equipment for container corner fitting processing that can not only complete the separation and cutting of the cast container corner fitting workpiece at a lower cost, but also ensure that no excessive mechanical damage is caused to the workpiece surface during the separation and cutting process.

[0009] The tooth limiting mechanism comprises a guide component for guiding and limiting the top-tightening tooth, and an elastic component for pushing the top-tightening tooth inward to close a group of top-tightening tooth;

[0010] The multifunctional cutting mechanism comprises a cutting rod which is longitudinally movably installed in the housing, the front end of the cutting rod is pointed, the inner end of the cutting rod is connected to the piston rod end of the driving oil cylinder through an elastic connecting piece, the inner end of the cutting rod is fixedly installed with a corresponding ultrasonic transducer, and the ultrasonic transducer is connected to an external ultrasonic generator; the piston rod end of the driving oil cylinder extends, the cutting rod extends and presses between the inner ends of a group of pressing teeth, and the elastic connecting piece is compressed; when the compression amount of the elastic connecting piece reaches L1, the cutting rod pushes away the pressing teeth, so that a group of pressing teeth presses against the side wall of the workpiece; the cutting rod continues to move forward under the drive of the driving oil cylinder to press against the connection of the workpiece; the piston rod of the driving oil cylinder continues to extend, the elastic connecting piece is further compressed, and when the compression amount of the elastic connecting piece reaches L2, the ultrasonic transducer is triggered, and under ultrasonic vibration, the pointed end of the cutting rod ultrasonically cuts the connection of the workpiece.

[0011] A group of corresponding tightening balls with ends located outside 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.

[0012] The elastic connecting member adopts a coil spring, and the inner end of the cutting rod and the piston rod of the driving cylinder are respectively fixed with corresponding fixed ring plates. The two ends of the elastic connecting member are respectively fixed to the corresponding fixed ring plates, and the ultrasonic transducer is fixedly sleeved inside the elastic connecting member.

[0013] The guide assembly includes a guide shaft that transversely passes through the clamping tooth part, and the guide shaft is fixed to the housing by a threaded connection. The elastic assembly adopts a compression spring, and the elastic assembly is sleeved on the guide shaft in a compressed state, and the two ends of the elastic assembly respectively abut against the side walls of the housing and the clamping tooth part.

[0014] The guide assembly further comprises a clamping plate fixedly connected to the inner end of the clamping toothed member, and guide grooves matching the clamping plate are arranged on both sides of the housing, and the clamping plate can be movably installed in the guide grooves.

[0015] The outer ends of the tightening teeth are respectively arranged in an inclined shape, and the outer ends of the tightening teeth are respectively arranged with corresponding anti-slip grooves.

[0016] A polymer damping material layer is fixedly installed on the inner wall of the casing. The polymer damping material layer is arranged in a sheet shape and is fixed to the inner wall of the casing by bonding.

[0018] A corresponding handle connecting rod is fixedly connected to the front side of the housing backwards, and a corresponding handle is fixedly connected to the handle connecting rod upwards.

[0019] A corresponding pushing pad is fixedly connected to the cylinder body of the driving oil cylinder at the rear.

[0020] Advantages of the present invention:

[0021] 1) The present invention uses a tooth limit mechanism to allow the top teeth to be in a closed state, so as to ensure that the top teeth can enter the gap between the workpieces and can move laterally. During the cutting process, the cutting rod is driven by the driving cylinder to first press between the inner ends of a group of top teeth. When the compression amount of the elastic connector of the multifunctional cutting mechanism reaches L1, the thrust force of the cutting rod is sufficient to drive the top teeth to move outward laterally, thereby making way for the cutting rod to extend outward, so as to drive a group of top teeth to press against the side wall of the workpiece. At this time, A lateral fixation can be formed to fix and clamp the top gear piece between the intervals of the workpiece, and the top gear piece only plays a limiting role. In this way, when the cutting rod moves forward to the joint of the workpiece, as the piston rod of the driving oil cylinder continues to extend, the elastic joint piece can be further compressed. When the compression amount of the elastic joint piece reaches L2, that is, when the cutting rod has sufficient pressure on the joint of the workpiece, the ultrasonic transducer is triggered to make the pointed end of the cutting rod smoothly cut the joint of the workpiece under the action of high-frequency vibration and sufficient pressure. In this way, the separation and cutting of the cast container corner workpiece can be completed at a lower cost, and it can ensure that no excessive mechanical damage is caused to the surface of the workpiece during the separation and cutting process.

[0022] 2) The inner end surfaces of a group of tightening teeth of the present invention are respectively rollingly mounted with tightening balls whose ends are located on the outside of the tightening teeth. The tightening balls 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 present invention.

[0023] 3) The guide assembly of the present invention includes a guide shaft that transversely penetrates the top clamping tooth part, and a clamping plate fixed to the inner end of the top clamping tooth part. The clamping plate can be movably installed in the guide grooves on both sides of the casing. Through two guide limiters, it is ensured that the top clamping tooth part still has sufficient stability in the ultrasonic vibration environment, so as to further ensure the practical effect of the present invention.

[0024] 4) The inner wall of the housing of the present invention is fixedly installed with a polymer damping material layer, which is arranged in a sheet shape and fixed to the inner wall of the housing by bonding. This is to reduce the outward transmission of vibration during the ultrasonic cutting operation, thereby reducing the impact of ultrasonic vibration on the overall structural stability of the present invention and reducing the labor intensity of construction personnel.

[0025] 5) An n-shaped mounting plate is fixedly connected to the rear side of the casing of the present invention, and a lifting rod is fixedly connected upward to the n-shaped mounting plate. During use, the present invention can be hoisted as a whole on the corresponding frame through the lifting rod, so as to significantly reduce the labor intensity of construction personnel; and a handle connecting rod is fixedly connected to the front side of the casing of the present invention, and a handle is fixedly connected to the handle connecting rod upward. During use, the overall position of the present invention can be controlled by the handle.

It is very convenient and the operation is highly controllable. BRIEF DESCRIPTION OF THE DRAWINGS
