Description

Technical Field

[0001] This application relates to the technical field of equipment for machining mold steel, and in particular to a milling machine for machining mold steel. Background Technology

[0002] Mold steel is an important type of steel used to manufacture various molds, such as cold stamping dies, hot forging dies, and die casting molds. In many industrial sectors such as machinery manufacturing, radio instruments, motors, and electrical appliances, molds are key processing tools for manufacturing parts. Their quality is directly related to the quality of pressure processing, product precision and output, and production costs. The quality and service life of molds depend on reasonable structural design, processing accuracy, mold materials, and heat treatment.

[0003] In the production and processing of mold steel, milling machines are an indispensable key piece of equipment. Milling machines for mold steel processing use milling cutters to mill the mold steel workpiece, which can accurately remove the excess parts of the workpiece, thereby forming the required shape and size.

[0004] One of the processing steps is to grind the sides of the mold steel to ensure its verticality. Typically, the mold steel is fixed vertically by a gantry frame and then driven longitudinally towards the milling cutter. During the grinding process, the milling cutter applies external force to both sides of the mold steel. Because the surface of the tray used to hold the mold steel in the existing technology is smooth, the mold steel is prone to shift longitudinally during the grinding process due to the external force applied by the milling cutter, resulting in poor stability of the mold steel. Utility Model Content

[0005] This application provides a milling machine for stable machining of mold steel.

[0006] The milling machine for machining mold steel provided in this application adopts the following technical solution:

[0007] A milling machine for machining mold steel includes an operating table. A sliding mechanism and a grinding mechanism are fixed on the operating table. The grinding mechanism is connected to both sides of the sliding mechanism. A rotating mechanism, a longitudinal fixing mechanism, and a vertical fixing mechanism are connected to the sliding mechanism. The rotating mechanism is used to place the mold steel. The longitudinal fixing mechanism is connected longitudinally to the front and rear sides of the sliding mechanism and is used to abut against the front and rear sides of the mold steel, respectively. The vertical fixing mechanism is located above the rotating mechanism and is used to abut against the upper side of the mold steel from top to bottom.

[0008] Preferably, the sliding mechanism includes a guide rail fixed on the operating table and a slider slidably connected to the guide rail along the longitudinal direction; the rotating mechanism includes a rotating motor and a placement plate, the rotating motor is installed inside the slider, the placement plate is connected to the output shaft of the rotating motor, and the placement plate is used to place mold steel.

[0009] Preferably, the grinding mechanism includes a first fixed seat and a second fixed seat, which are laterally distributed on both sides of the guide rail. The first fixed seat is driven to connect a first abutment plate and a first milling cutter, which are longitudinally distributed. The second fixed seat is driven to connect a second abutment plate and a second milling cutter, which are longitudinally distributed. The first abutment plate and the second abutment plate are symmetrically distributed, as are the first milling cutter and the second milling cutter.

[0010] Preferably, the longitudinal fixing mechanism includes a first support base and a second support base, which are distributed longitudinally on the front and rear sides of the slider. A first fixing block is driven to the first support base, and a second fixing block is driven to the second support base. The first fixing block and the second fixing block are respectively used to abut against the front and rear sides of the mold steel.

[0011] Preferably, the first fixing block and the second fixing block are made of rubber.

[0012] Preferably, the vertical fixing mechanism includes an L-shaped bracket and a hydraulic press. The L-shaped bracket includes a first frame and a second frame. The first frame and the second frame are vertically distributed. The first frame is connected to the rear side of the slider. The second frame is located above the placement plate. The hydraulic press is fixed on the second frame. The output shaft of the hydraulic press is used to abut against the upper surface of the mold steel from top to bottom.

[0013] Preferably, a pressure block is connected to the output shaft of the hydraulic press. The pressure block is used to connect to the upper side of the mold steel and has a groove with the same diameter as the output shaft of the hydraulic press. The output shaft of the hydraulic press passes through the groove.

[0014] In summary, this application includes at least one of the following beneficial technical effects:

[0015] 1. By setting a longitudinal fixing mechanism and a vertical fixing mechanism that cooperates with the longitudinal fixing mechanism, the mold steel is subjected to longitudinal and vertical constraint forces, making it less likely to shift longitudinally during the grinding process due to the external force applied to the surface to be ground by the grinding mechanism. Compared with the prior art, the milling machine for processing mold steel of this application can better ensure the stability of mold steel during grinding, thereby improving the processing yield.

[0016] 2. By setting a pressure block connected to the output shaft of the hydraulic press, the pressure block has a groove with the same diameter as the output shaft of the hydraulic press. The output shaft of the hydraulic press presses the mold steel onto the placement plate by abutting against the pressure block. The fit between the output shaft and the groove of the pressure block can prevent the pressure block from moving due to vibration during the grinding of the mold steel, thus ensuring the pressing effect.

[0021] The present application will be further described in detail below with reference to the accompanying drawings.

[0022] This application provides a milling machine for machining mold steel, such as Figures 1 to 3 As shown, the device includes an operating table 1, on which a sliding mechanism 2 and a grinding mechanism 3 are fixed. The grinding mechanism 3 is connected to both sides of the sliding mechanism 2. The sliding mechanism 2 is connected to a rotating mechanism 4, a longitudinal fixing mechanism 5, and a vertical fixing mechanism 6. The rotating mechanism 4 is used to place the mold steel. The longitudinal fixing mechanism 5 is connected longitudinally to the front and rear sides of the sliding mechanism 2 and is used to abut against the front and rear sides of the mold steel, respectively. The vertical fixing mechanism 6 is located above the rotating mechanism 4 and is used to abut against the upper side of the mold steel from top to bottom.

[0023] During the operation, the mold steel is first placed on the rotating mechanism 4. The rotating mechanism 4 drives the mold steel so that its two opposite sides are parallel to the grinding mechanism 3. Then, the longitudinal fixing mechanism 5 abuts against the front and rear sides of the mold steel along the longitudinal direction, and the vertical fixing mechanism 6 abuts against the upper side of the mold steel from above. Next, the sliding mechanism 2 drives the rotating mechanism 4 to move longitudinally and approach the grinding mechanism 3. Finally, the grinding mechanism 3 is driven to grind both sides of the mold steel. If it is necessary to change the grinding surface of the mold steel, after completing the above steps, the sliding mechanism 2 can take the rotating mechanism 4 away from the grinding mechanism 3, and the longitudinal fixing mechanism 5 and the vertical fixing mechanism 6 can be removed from the mold steel. The rotating mechanism 4 drives the mold steel to rotate, and then the longitudinal fixing mechanism 5 and the vertical fixing mechanism 6 are fixed to the mold steel again before grinding.

[0024] By setting a longitudinal fixing mechanism 5 and a vertical fixing mechanism 6 that cooperates with the longitudinal fixing mechanism 5, the mold steel is subjected to longitudinal and vertical constraint forces, making it less likely to shift longitudinally during the grinding process due to the external force applied to the surface to be ground by the grinding mechanism 3. Compared with the prior art, the milling machine for processing mold steel of this application can better ensure the stability of the mold steel during grinding, thereby improving the processing yield.

[0025] like Figure 2 As shown, the sliding mechanism 2 includes a guide rail 21 fixed on the operating table 1 and a slider 22 slidably connected to the guide rail 21 along the longitudinal direction. The rotating mechanism 4 includes a rotating motor 41 and a placement plate 42. The rotating motor 41 is installed inside the slider 22, and the placement plate 42 is connected to the output shaft of the rotating motor 41. The placement plate 42 is used to place the mold steel. Specifically, the output shaft of the rotating motor 41 is located at the center of the slider 22. The size of the placement plate 42 is smaller than the size of the slider 22. The distance from the outermost end of the placement plate 42 to the center is smaller than the longitudinal length of the slider 22. When the placement plate 42 rotates, the end will not exceed the range of the slider 22.

[0026] like Figure 2 As shown, the grinding mechanism 3 includes a first fixed seat 31 and a second fixed seat 32. The first fixed seat 31 and the second fixed seat 32 are distributed laterally on both sides of the guide rail 21. The first fixed seat 31 is driven to connect a first abutting plate 33 and a first milling cutter 34 laterally. The first abutting plate 33 and the first milling cutter 34 are distributed longitudinally. The second fixed seat 32 is driven to connect a second abutting plate 35 and a second milling cutter 36 laterally. The second abutting plate 35 and the second milling cutter 36 are distributed longitudinally. The first abutting plate 33 and the second abutting plate 35 are symmetrically distributed, as are the first milling cutter 34 and the second milling cutter 36.

[0027] During operation, the first abutting plate 33 and the second abutting plate 35 are first driven and abut against the two sides of the mold steel in the transverse direction. The position of the mold steel is adjusted so that its two sides in the transverse direction are parallel to the first milling cutter 34 and the second milling cutter 36, respectively. Then, the sliding mechanism 2 drives the mold steel to the space between the first milling cutter 34 and the second milling cutter 36. The first milling cutter 34 and the second milling cutter 36 are close to the two sides of the mold steel and cooperate with the sliding mechanism 2. When the first milling cutter 34 and the second milling cutter 36 rotate, the sliding mechanism 2 drives the mold steel to move longitudinally at a certain speed.

[0028] like Figure 3 As shown, the longitudinal fixing mechanism 5 includes a first support base 51 and a second support base 52. The first support base 51 and the second support base 52 are distributed longitudinally on the front and rear sides of the slider 22. A first fixing block 53 is driven to the first support base 51, and a second fixing block 54 is driven to the second support base 52. The first fixing block 53 and the second fixing block 54 are respectively used to abut against the front and rear sides of the mold steel. The first fixing block 53 and the second fixing block 54 are made of rubber. By driving the first fixing block 53 and the second fixing block 54 to abut against the front and rear ends of the mold steel, the rubber material of the first fixing block 53 and the second fixing block 54 can reduce scratches on the mold steel during the fixing process, thus ensuring the product yield.

[0029] like Figure 3 As shown, the vertical fixing mechanism 6 includes an L-shaped bracket 61 and a hydraulic press 62. The L-shaped bracket 61 includes a first frame 611 and a second frame 612. The first frame 611 and the second frame 612 are vertically distributed, and the second frame 612 is parallel to the shelf 42. The first frame 611 is connected to the rear side of the slider 22 and can be driven by the slider 22. The second frame 612 is located above the shelf 42. The hydraulic press 62 is fixed on the second frame 612, and the output shaft of the hydraulic press 62 is used to press down from top to bottom. A pressure block 7 is connected to the output shaft of the hydraulic press 62 attached to the upper surface of the mold steel. The pressure block 7 is used to connect to the upper side of the mold steel and has a groove 71 with the same diameter as the output shaft of the hydraulic press 62. The output shaft of the hydraulic press 62 passes through the groove 71. In this way, the output shaft of the hydraulic press 62 presses the mold steel onto the placement plate 42 by abutting against the pressure block 7. The cooperation between the output shaft and the groove 71 of the pressure block 7 can prevent the pressure block 7 from moving due to vibration during the grinding of the mold steel, thus ensuring the pressing effect.

[0030] The above are all preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
