Description

Technical Field

[0001] The invention relates to the technical field of casting processing, and in particular to a cutting device based on a gate of a casting. Background Art

[0002] The gate is a hole or channel used to pour molten metal during the casting process. Its main function is to guide the molten metal into the mold cavity, ensure that the molten metal can smoothly fill the mold cavity, and isolate gas and impurities to prevent them from entering the mold cavity. The design of the gate has an important impact on the quality and production efficiency of the casting. There are various types of gates, and the common ones are straight gates, oblique gates, side gates and bottom gates. The straight gate is suitable for the casting of large and small and medium-sized castings. The path is short and straight, and the metal flows quickly. The oblique gate is suitable for castings with complex shapes and uneven wall thicknesses, which helps the sand core to vent and the metal liquid to flow. The side gate is suitable for slender and tubular castings, which can allow the metal to fill multiple parts at the same time. The bottom gate is suitable for the case where the bottom surface of the casting is large, and the metal can be filled from the bottom to the top to reduce the mixing of gas.

[0003] A Chinese patent application document with application publication number CN112872337A discloses an automatic gate cutting device, including a hanging structure for hanging a sand casting whose gate is to be cut, the hanging structure runs along a running track and is limited when it enters the position of a limiting structure; a cutting device driven by a linkage structure is matched and aligned with the hanging structure, at which time the cutting device can continue to cut the gate position of the sand casting until it reaches the final end and the cutting is completed. The linkage structure can also drive the cutting device to reset when it reaches the final end, so as to prepare to be linked with the next hanging structure and cut the sand casting hung on the next hanging structure again.

[0004] In the related art, when cutting the gate, it cannot adapt to the shape of the gate, and because the gate and the end face of the workpiece do not present a certain angle during cutting, the cutting device cannot be close to the side of the workpiece during cutting, resulting in an irregular cross-section, so that trimming is required after cutting is completed. Summary of the invention

[0005] The present invention provides a cutting device based on the gate of a casting, aiming to solve the technical problem in the related art that the gate and the end face of the workpiece do not present a certain angle during cutting, and the cutting device cannot be close to the side of the workpiece during cutting, resulting in an irregular cut section.

[0006] The cutting device based on the gate of the casting of the present invention comprises: a machine base, a clamping assembly and a cutting device, the casting is placed at the center position of the machine base, including: a clamping assembly installed in the machine base for clamping the side of the casting, two groups of positioning assemblies symmetrically arranged on both sides of the gate, the positioning assembly is rotatably and slidably installed on the machine base up and down, the positioning assembly comprises a V-shaped plate for clamping the gate, a driving member driving the positioning assembly to slide up and down, a driving source driving the positioning assembly to approach / move away from the gate, two groups of adjustment assemblies arranged along the circumference of the gate axis, the adjustment assembly comprises a V-shaped arm and two L-shaped rods, the V-shaped arm is hinged on the positioning assembly, and the distance from any point on the hinge axis to the two side surfaces of the V-shaped plate is equal, the hinge axes of the two V-shaped arms are perpendicular to the axis of the gate, the V-shaped ends of the V-shaped arm are respectively slidably connected to the two L-shaped rods, and are connected to the ends of the two L-shaped rods close to the front side / rear side, and a cutting device, the cutting device is installed on the V-shaped arm, and the cutting device is used when the L-shaped rod is retracted to the extreme position.

[0007] The effect is that: when the V-shaped plate is set to cut the gate of the casting, the gate is positioned and the axis of the gate is determined by using the V-shaped plate, and the intersection plane between the gate and the casting is determined along the axis of the gate by cooperating with the V-shaped arm and the L-shaped rod, and the cutting device set on the V-shaped arm is adjusted to cut along the intersection plane between the gate and the casting, so as to solve the problem of irregular and uneven end surface when the gate is cut.

[0008] Preferably, the ends of the two L-shaped rods' horizontal sections that are close to each other are provided with matching protrusions and grooves so that the horizontal sections of the two L-shaped rods on the same side remain coaxial when they abut against each other. The effect is that by providing matching protrusions and grooves, the two L-shaped rods on the same side remain coaxial during positioning, thereby ensuring that the cutting devices on both sides are located in the same plane.

[0009] Preferably, the positioning assembly includes a positioning rod, a V-shaped plate and a driving member. The positioning rod is horizontally arranged on the machine base and slides up and down along the machine base. The positioning rod rotates around its own axis. The V-shaped plate is arranged on the end surface where the two positioning rods are close to each other. The two V-shaped plates clamp the gate, and the driving member is arranged in a direction perpendicular to the top surface of the V-shaped plate.

[0010] Preferably, the adjustment component is arranged on the positioning rod, and the adjustment component includes a V-shaped arm and an L-shaped rod. The V-shaped arm is sleeved on the positioning rod, and the V-shaped arm rotates around the axis of the positioning rod. The V-shaped arm is slidingly connected to the L-shaped rod.

[0012] Preferably, the V-shaped plate is formed by hinged two side plates, and bolts for fixing the opening angle are provided at the hinge. The effect is that by setting the V-shaped plate as two side plates with adjustable angles, when cutting gates of different diameters, the angle between the V-shaped plates can be adjusted to adapt to gates of different diameters.

[0013] Preferably, a roller is provided on the end surface of the V-shaped plate in contact with the gate. The effect is that by providing a roller on the end surface of the V-shaped plate in contact with the gate, the friction between the V-shaped plate and the gate can be reduced during adjustment, thereby further ensuring the accuracy of the adjustment and reducing the loss of the equipment.

[0014] Preferably, a support arm is provided on the V-shaped arm, and the support arm is located at the center of the V-shaped arm in left and right side views. The effect is that the support arm is set at the center of the V-shaped arm to ensure that the cutting part of the cutting device and the horizontal sections of the two L-shaped rods are in the same plane, and the cutting part is ensured to cut along the intersection surface of the gate and the casting during cutting.

[0015] Preferably, a cutting device is provided on the sliding sleeve of the support rod. When the L-shaped rod is contracted to the extreme position, the lower end surface of the cutting portion of the cutting device coincides with the lower end cross-sections of the two rotating sleeves.

[0017] 1. When cutting the gate of a casting, the V-shaped plate is used to locate the axis of the gate, and the V-shaped arm and L-shaped rod are further used to determine the intersection plane between the gate and the casting along the axis of the gate. Then, the cutting device provided on the V-shaped arm is used to cut along the intersection plane of the gate and the casting to solve the problem of irregular and uneven end surface when cutting the gate.

[0018] 2. By setting matching protrusions and grooves at the front ends of the horizontal sections of the two L-shaped rods, the two L-shaped rods on the same side remain coaxial during positioning to ensure that the cutting devices on both sides are located in the same plane, thereby increasing the flatness of the gate cutting section.

[0027] Embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0028] like Figures 1 to 6 As shown, the cutting equipment based on the casting gate of the present invention includes a machine base 1, a clamping assembly 2, a cutting device 11, a gate 12 and a casting 13. The casting 13 is placed at the center of the machine base 1. The clamping assembly 2 is composed of four clamping plates distributed circumferentially to limit the casting 13 placed at the center of the machine base 1. It also includes a positioning assembly 3 and an adjusting assembly 4. Two groups of positioning assemblies 3 are symmetrically arranged on both sides of the gate 12. In the embodiment, the positioning assembly 3 is arranged along the left and right directions as an example. The positioning assembly 3 moves from the left and right sides to the middle to position the gate 12. Two groups of adjusting assemblies 4 are arranged around the circumference of the axis of the gate 12. The adjusting assembly 4 is installed on the positioning assembly 3. The adjusting assembly 4 makes the cutting part of the cutting device 11 located on the boundary line between the gate 12 and the casting 13, and the cutting device 11 cuts the gate 12.

[0029] like Figures 2 to 5As shown, the above-mentioned positioning assembly 3 includes a positioning rod 31, a V-shaped plate 32 and a driving member 33. The positioning rod 31 is horizontally arranged on the machine base 1 along the left and right direction, and slides up and down along the machine base 1 under the action of the driving member 33. The positioning rod 31 rotates around its own axis. The driving source 34 makes the positioning rod 31 slide back and forth in the horizontal direction. The driving source 34 is preferably an electric telescopic rod to adapt to the horizontal displacement of the axis of the gate 12 after the inclination. The V-shaped plate 32 is arranged on the end surface where the two positioning rods 31 are close to each other. The two V-shaped plates 32 clamp the gate 12. When clamping, the V-shaped plate 32 drives the positioning rod 31 to rotate to adapt to the inclined state of the gate 12. The driving member 33 is arranged on the positioning rod 31 in a direction perpendicular to the top surface of the V-shaped plate 32.

[0030] like Figures 4 to 5 As shown, the driving member 33 includes a second driving source 331 and a support rod 332. The support rod 332 is arranged on the positioning rod 31. The support rod 332 is perpendicular to the top surface of the V-shaped plate 32. The second driving source 331 causes the support rod 332 to slide along the axial direction of the gate 12. The second driving source 331 is preferably an electric telescopic rod. The upper ends of the two support rods 332 are both V-shaped and their openings are opposite to each other. When the support rod 332 moves upward, the V-shaped end of the support rod 332 will resist the hemispherical part of the upper end of the gate 12, and at the same time drive the positioning rod 31 to move downward along the axis of the gate 12.

[0031] like Figures 2 to 5 As shown, the V-shaped plate 32 is formed by hinged two side plates, and the angle between the two side plates can be adjusted. Bolts for fixing the opening angle are provided at the hinge. After the V-shaped plate 32 is adjusted to the required angle, it is fixed by bolts to adapt to gates 12 of different diameters. Rollers are provided on the end surfaces of the V-shaped plate 32 abutting against the gate 12. After the V-shaped plate 32 abuts against the gate 12, the rollers will abut against the gate 12 to reduce the friction of the V-shaped plate 32 moving relative to the gate 12.

[0032] like Figures 1 to 6 As shown, the two groups of the above-mentioned adjustment components 4 are arranged along the circumference of the axis of the gate 12, and the adjustment components 4 are arranged on the positioning rod 31. The adjustment components 4 include a V-shaped arm 42 and an L-shaped rod 43. The V-shaped arm 42 is sleeved on the positioning rod 31, and the V-shaped arm 42 rotates around the axis of the positioning rod 31. The V-shaped arm 42 is slidably connected to the L-shaped rod 43. The L-shaped rod 43 is provided with a maximum length and a minimum length relative to the telescopic state of the V-shaped arm 42. The other section of the L-shaped rod 43 is horizontally arranged along the left and right directions. The telescopic parts of the V-shaped arm 42 and the L-shaped rod 43 are embedded with springs. The elastic coefficients of the two embedded springs are the same and both are small. A rotating sleeve 431 is sleeved on the horizontal section of the L-shaped rod 43. The rotating sleeve 431 is arranged to reduce the friction force of the L-shaped rod 43 when it moves relative to the casting 13.

[0033] like Figures 2 to 6As shown, the adjacent ends of the two L-shaped rods 43 located at the front / rear sides are connected, and the horizontal sections of the two L-shaped rods 43 on the same side will abut against each other during positioning. The adjacent ends of the horizontal sections of the two L-shaped rods 43 are provided with matching protrusions and grooves on the end surfaces, and when the two L-shaped rods 43 on the same side abut against each other, the protrusions and grooves cooperate to keep the horizontal sections coaxial.

[0034] like Figures 1 to 6 As shown, a support arm 421 is provided on the above-mentioned V-shaped arm 42, and the support arm 421 is arranged on the end surfaces of the two V-shaped arms 42 that are away from each other. The support arm 421 is L-shaped, and the support arm 421 is located at the center position of the V-shaped arm 42 in left and right side views. The vertical section of the support arm 421 is always located on the symmetry axis of the two arms of the V-shaped arm 42, and a cutting device 11 is provided on the sliding sleeve at the lower end of the vertical section of the support arm 421. When the L-shaped rod 43 is contracted to the shortest length relative to the V-shaped arm 42, the lower end surface of the cutting portion of the cutting device 11 coincides with the lower end section of the two rotating sleeves 431.

[0035] The implementation principle of the embodiment of the present invention is as follows: the casting 13 is placed at the center of the machine base 1, and the four clamping plates of the clamping assembly 2 move from the periphery to the middle to position the casting 13 so that the casting 13 is located at the center of the machine base 1. Further, under the action of the driving source 34, the positioning rod 31 moves toward the gate 12 in the left and right directions, and the V-shaped plate 32 positions the gate 12 until the axis of the gate 12 is perpendicular to the top surface of the V-shaped plate 32. The positioning rod 31 rotates and moves horizontally in the front and rear directions during positioning to adapt to the inclination of the gate 12. The front ends of the horizontal sections of the two L-shaped rods 43 are abutted against each other, and the horizontal sections of the L-shaped rods 43 on the same side are coaxial. The rollers on the inner side of the V-shaped plate 32 abut against the side of the gate 12, and the driving source 34 drives the positioning rod 31 to move toward the gate 12 in the left and right directions. The driving source 331 is started to make the support rod 332 move upward along the axis direction of the gate 12. When the V-shaped opening at the upper end of the support rod 332 abuts against the hemispherical part of the gate 12, the driving source 331 will drive the positioning rod 31 to move downward, and the V-shaped arm 42 sleeved on the positioning rod 31 moves downward. The horizontal sections of the L-shaped rods 43 on both sides of the V-shaped arm 42 abut against the casting 13 at the same time. When the V-shaped arm 42 continues to move downward, the L-shaped rods 43 on both sides shrink to the minimum length inside the V-shaped arm 42, and the lower end surface of the cutting part of the cutting device 11 coincides with the lower end cross-section of the two rotating sleeves 431. The cutting device 11 cuts the gate 12. After the cutting is completed, the casting 13 is released from the positioning, the casting 13 is removed, and the next workpiece to be processed is placed.
