Technical Field

[0001] The invention relates to the technical field of metal cutting, in particular to a gate cutting mechanism for an end cover casting. Background Art

[0002] Castings are metal parts or blanks with certain shapes, sizes and properties obtained by casting. Usually in metal casting, they are used for the entrance and channel of molten metal into the casting cavity. After the casting is cooled and formed, a gate is formed, which usually needs to be cut off by a corresponding cutting mechanism.

[0003] The existing Chinese patent publication number is: CN220144866U, the name of the patent is "a casting cutting device", the patent includes "a bottom plate, two cutting assemblies with the same structure are installed in parallel on the bottom plate, the two cutting assemblies move relative to or towards each other on the bottom plate, two driving devices are arranged in parallel on the bottom plate to drive the two cutting assemblies to move respectively, and two movable cutting devices are arranged on the bottom plate to adjust the cutting position of the casting at all times; it can not only cut different workpieces at the same time, but also process both sides of a larger workpiece at the same time, thereby improving the processing efficiency";

[0004] The gates of some end cover castings are often located in the center of the end cover.

[0029] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0030] The end cover casting mainly includes an end cover of a disc body and a cylindrical gate column located at the center of the disc end cover. The gate column usually needs to be cut off by a corresponding cutting mechanism. The method commonly used for this type of casting is to clamp and fix the end cover, and then cut the cylindrical gate column by a cutting device so that the surface where the gate column is located is flush with the cover surface of the end cover. When the cutting saw has completed cutting the gate of the end cover casting, the fixed limit of the end cover is released, and then the end cover of the next gate to be cut is re-fixed. Each time an end cover gate is cut, the cutting needs to be suspended when the end cover is fixed and released, so that continuous cutting of the end cover gate cannot be formed, and efficiency is difficult to improve.

[0031] See also Figure 1-6 , an end cap casting gate cutting mechanism provided by an embodiment of the present invention comprises a base box 1, a slideway unit 1.1 for sliding the end cap casting is provided on the top of the base box 1;

[0032] The cutting unit 2 comprises a saw blade 2.1 located on the slideway opening unit 1.1, and the saw blade 2.1 can cut the gate of the end cover casting sliding on the slideway opening unit 1.1 during operation;

[0033] The conveying assembly 3 comprises a conveying belt 3.1 whose track line has an area parallel to the track line of the slideway opening unit 1.1, and a plurality of pushing units 3.2 are fixed on the belt body of the conveying belt 3.1, and the pushing units 3.2 can provide driving force for the end cover casting on the slideway opening unit 1.1 to slide toward the saw blade 2.1;

[0034] The base box 1 is a rectangular box, and a maintenance door that can be opened and closed is provided on the side of the base box 1. The slideway unit 1.1 is connected to the inside of the base box 1. The cylindrical gate column of the end cover casting can extend into the inside of the base box 1 through the slideway unit 1.1. The conveyor belt 3.1 of the conveying assembly 3 drives the pushing unit 3.2 to circulate and rotate in the base box 1.

[0035] In actual use, the starting end of the movement of the slideway unit 1.1 close to the linear conveying of the conveyor belt 3.1 is taken as the loading position, and the end cover casting is placed at the loading position, so that the cylindrical gate column of the end cover casting can extend into the base box 1 through the slideway unit 1.1, and the gate column overlaps with the movement trajectory of the pushing unit 3.2. The end cover casting is located above the base box 1. When the pushing unit 3.2 passes through the gate column extending into the base box 1, the pushing unit 3.2 is connected with the gate column, and the pushing unit 3.2 The gate column of the end cover casting is driven to move synchronously toward the saw blade 2.1, so that the end cover casting on the slideway unit 1.1 also slides synchronously toward the saw blade 2.1, so that the gate column of the end cover casting is cut by the saw blade 2.1 until the gate column of the end cover casting is separated from the end cover casting, so that the cut end cover casting is directly located on the top of the base box 1. The whole process is simple to operate, and the whole cutting process can be carried out continuously without intermittent pauses, thereby forming a continuous cutting of the end cover gate, and the gate cutting efficiency is improved.

[0036] In another embodiment provided by the present invention, the slideway opening unit 1.1 is a straight opening parallel to the length direction line of the base box 1, the saw blade 2.1 is located in the middle of the length direction of the straight opening, and the saw blade 2.1 divides the slideway opening unit 1.1 into a loading area section and a unloading area section, wherein the loading area section is a straight line section between the saw blade 2.1 and the loading position, and the unloading area section is a straight line section between the saw blade 2.1 and the end section of the slideway opening unit 1.1;

[0037] A limit rod unit 1.2 is provided on both sides of the slideway opening unit 1.1. The limit rod unit 1.2 includes rotating rods 1.21 located on both sides of the straight strip opening. The axis of each rotating rod 1.21 is parallel to the length direction line of the straight strip opening. The rotating rod 1.21 is rotatably installed on the top of the base box 1. The rotating rod 1.21 is a cylindrical smooth rod. The two rotating rods 1.21 form a limit track for the end cover casting to slide on the top of the base box 1. A spiral strip 1.22 is wound and fixed on the rod body of each rotating rod 1.21 parallel to the unloading area section, and a first motor 1.23 is fixed at one end of each rotating rod 1.21.

[0038] In actual use, after the end cover casting completes the cutting of the gate column, the end cover casting is located in the unloading area. At this time, the spiral bar 1.22 is driven by the rotating rod 1.21 under the drive of the first motor 1.23. Under the action of the friction between the spiral bar 1.22 and the end cover casting, it is conducive to the sliding of the end cover casting after the cutting of the gate column on the limiting track, thereby unloading the end cover casting after the cutting of the gate column from the base box 1.

[0039] In another embodiment provided by the present invention, the cutting unit 2 also includes a receiving opening 2.2 for receiving the saw blade 2.1, the receiving opening 2.2 is connected to the slide opening unit 1.1, the sawing surface of the saw blade 2.1 is parallel to the top surface of the base box 1, and the cutting unit 2 also includes a second motor 2.3 located in the base box 1, and the output shaft of the second motor 2.3 is vertically fixed to the saw blade 2.1.

[0040] In another embodiment provided by the present invention, the belt surface of the conveyor belt 3.1 is perpendicular to the horizontal plane, and both ends of the annular belt body of the conveyor belt 3.1 are driven and adapted to be equipped with driving rollers 3.3 rotatably mounted on the base box 1, and the conveyor belt 3.1 between the driving rollers 3.3 is in a straightened state parallel to the slideway opening unit 1.1, and the driving rollers 3.3 are perpendicular to the horizontal plane. Furthermore, the cutting unit 2 is located at the center of the annular body of the conveyor belt 3.1, and the saw blade 2.1 of the cutting unit 2 is a circular saw, and the diameter value of the saw blade 2.1 is greater than the width value between the two parallel conveyor belts 3.1;

[0041] Specifically, the conveyor belt 3.1 has two parallel belt body areas in the base box 1, and each belt body area corresponds to a slide mouth unit 1.1. The end cover castings on the two slide mouth units 1.1 can be driven by the conveying component 3, and the two sides of the saw blade 2.1 respectively extend into the corresponding slide mouth unit 1.1. That is to say, the cutting unit 2 can cut the gate columns of the two end cover castings at the same time, further improving the gate cutting efficiency.

[0042] In another embodiment provided by the present invention, the pushing unit 3.2 includes a pushing column 3.21 located on the outer side of the conveyor belt 3.1, the axis of the pushing column 3.21 is parallel to the axis of the driving roller 3.3, a card interface 3.22 is provided on one side of the top of the pushing column 3.21, the card interface 3.22 is perpendicular to the moving direction line of the pushing column 3.21, the card interface 3.22 is at the front end of the pushing column 3.21 when it moves, the length direction line of the card interface 3.22 is flush with the axis of the pushing column 3.21, and the pushing column 3.21 is fixed to the conveyor belt 3.1 through the connecting frame unit 5;

[0043] In actual use, when the gate column of the end cover casting extends into the base box 1, the pushing unit 3.2 approaches the gate column along the conveyor belt 3.1. At this time, the gate column of the end cover casting is located on the moving trajectory of the pushing column 3.21, so that the gate column of the end cover casting will be located in the card interface 3.22, and then the pushing column 3.21 moves synchronously with the conveyor belt 3.1 under the connection of the connecting frame unit 3.23, thereby driving the gate column of the end cover casting to move along the slide mouth unit 1.1 toward the cutting unit 2.

[0044] In another embodiment provided by the present invention, a clamping assembly 4 is provided on the pushing column 3.21, and the clamping assembly 4 includes a clamping unit 4.1 located on the inner wall surface of the card interface 3.22, and a transmission unit 4.2 for driving the clamping unit 4.1 is installed on the pushing column 3.21, and the transmission unit 4.2 can control the loose clamping state of the clamping unit 4.1;

[0045] The clamping unit 4.1 includes a plurality of through openings 4.11 formed on the inner wall of the card interface 3.22, each through opening 4.11 is provided with a support column 4.12, the axis of which is perpendicular to the axis of the pushing column 3.21, a rubber anti-skid pad 4.13 is fixed to one end of the support column 4.12 located in the card interface 3.22, and a tooth groove portion 4.14 is formed on the column body of the support column 4.12 extending from the pushing column 3.21;

[0046] Further, the transmission unit 4.2 includes a gear ring 4.21 rotatably sleeved on the extrusion column 3.21, the ring surface of the gear ring 4.21 is parallel to the horizontal plane, and a spiral pattern 4.22 adapted to mesh with the tooth groove portion 4.14 is provided on the ring surface of the gear ring 4.21, and the spiral pattern 4.22 is a disc pattern, i.e., an Archimedean thread. The transmission unit 4.2 also includes a driving tooth assembly 4.23 installed on the base box 1, and the gear ring 4.21 can mesh and rotate when passing through the driving tooth assembly 4.23;

[0047] Specifically, the driving gear assembly 4.23 includes a first rack plate 4.231 and a second rack plate 4.232 located on both sides of the gear ring 4.21, the first rack plate 4.231 and the second rack plate 4.232 are both parallel to the length direction of the slideway opening unit 1.1, the tooth surface on the first rack plate 4.231 and the tooth surface on the second rack plate 4.232 are both facing the slideway opening unit 1.1, the first rack plate 4.231 and the second rack plate 4.232 are spaced apart in the length direction of the slideway opening unit 1.1, that is, the saw blade 2.1 is located in the middle position in the length direction of the slideway opening unit 1.1, and the slideway opening unit 1.1 is divided into a loading area section and a unloading area section, the end cover casting slides from the loading area section to the unloading area section after being cut by the saw blade 2.1, the first rack plate 4.231 is located in the loading area section, and the second rack plate 4.232 is located in the unloading area section;

[0048] In actual use, when the pushing unit 3.2 moves the gate column of the end cover casting along the slideway unit 1.1 toward the cutting unit 2, when the pushing unit 3.2 passes the first rack plate 4.231, the gear ring 4.21 meshes with the first rack plate 4.231. Since the bottom of the first rack plate 4.231 is vertically fixed to the inner bottom wall of the base box 1, the gear ring 4.21 meshes and rolls on the first rack plate 4.231. At this time, the gear ring 4.21 rotates clockwise on the pushing column 3.21. During the clockwise rotation of the gear ring 4.21, the spiral pattern 4.22 on the gear ring 4.21 and the tooth groove portion 4.14 are meshed and transmitted, so that each support column 4.12 moves toward the inside of the card interface 3.22, thereby applying an extrusion force to the gate column of the end cover casting in the card interface 3.22, and the gate column of the end cover casting is in a clamped state at the card interface 3.22.

[0049] When the pushing unit 3.2 passes through the second rack plate 4.232, the gear ring 4.21 meshes with the second rack plate 4.232. Since the bottom of the second rack plate 4.232 is vertically fixed to the inner top wall of the base box 1, the gear ring 4.21 meshes and rolls on the second rack plate 4.232. At this time, the gear ring 4.21 rotates counterclockwise on the pushing column 3.21. During the counterclockwise rotation of the gear ring 4.21, the spiral pattern 4.22 on the gear ring 4.21 and the tooth groove portion 4.14 mesh and transmit, so that each support column 4.12 moves toward the outside of the card interface 3.22, thereby canceling the extrusion force on the gate column of the end cover casting in the card interface 3.22, and the gate column of the end cover casting is in a loose state at the card interface 3.22.

[0050] During the whole process, the clamping assembly 4 can clamp the gate column of the end cap casting when the pushing unit 3.2 is in the loading area, and the clamping assembly 4 can loosen the gate column of the end cap casting when the pushing unit 3.2 is in the unloading area;

[0051] In other words, the gate column of the end cover casting is moved in the loading area section of the slideway unit 1.1 through the pushing unit 3.2, and the gate column of the cover casting is in a loose state at the card interface 3.22. After the pushing unit 3.2 passes the first rack plate 4.231, the gate column of the end cover casting is in a clamped state in the card interface 3.22. When the gate column of the end cover casting is cut by the saw blade 2.1, the gate column of the end cover casting is still in a clamped state in the card interface 3.22. After the gate column of the end cover casting is cut by the saw blade 2.1, the end cover casting is separated from the gate column of the end cover casting. After the pushing unit 3.2 passes the second rack plate 4.232, the gate column of the cover casting is in a loose state at the card interface 3.22, and the gate column of the cover casting is detached from the card interface 3.22 under the action of gravity.

[0052] In another embodiment provided by the present invention, the connecting frame unit 5 includes a supporting plate 5.1 fixed to the conveyor belt 3.1, the supporting plate 5.1 is provided with an insertion port 5.2 for the extrusion and pushing column 3.21 to movably penetrate, an auxiliary block 5.3 is fixed to the side of the supporting plate 5.1, a supporting wheel 5.4 is movably mounted at the bottom of the auxiliary block 5.3, the supporting wheel 5.4 can contact the inner bottom of the base box 1, and a locking component 6 that can be plugged into the support column 4.12 is fixed to the auxiliary block 5.3;

[0053] The locking assembly 6 includes an extension rod 6.1 fixed to the support column 4.12, and the locking assembly 6 also includes a square tube 6.2 fixed to the side of the auxiliary block 5.3. The extension rod 6.1 can be inserted into the tube body of the square tube 6.2. The end of the square tube 6.2 fixed to the auxiliary block 5.3 is the bottom end. A stopper bar 6.3 is movably hinged on the bottom end of the square tube 6.2. The stopper bar 6.3 is located inside the square tube 6.2. The length of the stopper bar 6.3 is greater than the length of the square tube. The inner diameter of the square tube 6.2 is greater than the length of the stopper bar 6.3. The stopper bar 6.3 is connected to the inner wall of the square tube 6.2 by a tension spring 6.4. In the natural state, the length direction line of the stopper bar 6.3 is parallel to the length direction line of the square tube 6.2. At this time, the stopper bar 6.3 is in a vertical state on the side of the auxiliary block 5.3.

[0054] Furthermore, there are three through-holes 4.11 on the inner wall of the card interface 3.22, one of which is located at the bottom of the groove of the card interface 3.22, and the other two through-holes 4.11 are located on the two side walls of the card interface 3.22, wherein the support pillar 4.12 located at the bottom of the groove of the card interface 3.22 is connected and fixed to the extension rod 6.1, and the axis of the support pillar 4.12 and the extension rod 6.1 are in the same straight line;

[0055] During actual use, when the gear ring 4.21 is in the initial position, the extension rod 6.1 is inserted into the square tube 6.2. When the gear ring 4.21 rotates clockwise on the squeezing and pushing column 3.21, the support column 4.12 moves toward the inside of the card interface 3.22. At the same time, the support column 4.12 drives the extension rod 6.1 to disengage from the square tube 6.2. When the extension rod 6.1 is completely disengaged from the square tube 6.2, the square tube 6.2 no longer limits the extension rod 6.1. At this time, the support column 4.12 is also in the maximum squeezing state for the gate column of the end cover casting in the card interface 3.22. As the gear ring 4.21 continues to rotate clockwise, the gate column of the end cover casting in the card interface 3.22 is in the maximum squeezing state. The hour hand rotates, so that the push column 3.21 and the gate column of the end cover casting rotate synchronously with the gear ring 4.21. In other words, at this time, the gate column of the end cover casting is in the process of moving from the slideway unit 1.1 toward the cutting unit 2, and at the same time, the gate column of the end cover casting is also in an axial rotation state, that is, the gate column of the end cover casting is in a state of being cut while rotating during the cutting process by the saw blade 2.1. The cutting track formed on the gate column of the end cover casting is a spiral disc shape, and the cutting depth is a spiral deepening process. The cutting position ends at the middle of the gate column of the end cover casting. The force is more uniform during cutting, which is also conducive to reducing burrs after cutting.

[0056] Furthermore, when the gear ring 4.21 rotates counterclockwise on the extrusion column 3.21, the stop bar 6.3 is still located on the deflection track surface of the extension rod 6.1, so that the extension rod 6.1 contacts the side of the stop bar 6.3 facing the center of the square tube 6.2, thereby limiting the counterclockwise axial rotation of the extrusion column 3.21. As the gear ring 4.21 continues to rotate counterclockwise, the support column 4.12 moves toward the outside of the card interface 3.22, and the gate column of the cover casting switches to a loose state at the card interface 3.22. At the same time, the support column 4.12 drives the extension rod 6.1 to move toward the square tube 6.2. When the extension rod 6.1 is fully inserted into the square tube 6.2, the square tube 6.2 again limits the extension rod 6.1.

[0057] It should be particularly noted that the square tube 6.2 can only limit the extension rod 6.1 on the anti-pillar 4.12 in the loose state, and cannot limit the extension rod 6.1 on the anti-pillar 4.12 in the clamped state; the baffle 6.3 can limit the extension rod 6.1 on the anti-pillar 4.12 in the clamped state and as it rotates counterclockwise on the squeezing column 3.21.

[0058] The above description is only by way of illustration of certain exemplary embodiments of the present invention. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
