Description

Technical Field

[0001] This utility model relates to the field of machining technology, and in particular to a double-headed chamfering device for mold steel. Background Technology

[0002] Mold processing refers to the processing of forming and blanking tools, and also includes shearing dies and die-cutting dies. Typically, a mold consists of an upper mold and a lower mold. A steel plate is placed between the upper and lower molds, and the material is formed under the action of a press. When the press is opened, a workpiece determined by the mold shape is obtained, or corresponding waste material is removed. Processed workpieces have sharp edges and burrs. When workpieces are mated, the sharp edges can damage the contact surfaces of the mating workpieces. When people come into contact with the workpieces, the sharp edges can also cause injury. Therefore, processed workpieces need to be chamfered. Currently, metal sheet chamfering is mostly done by skilled workers using simple handheld chamfering devices, which poses certain safety hazards, is inefficient, and is unsuitable for continuous chamfering operations. Utility Model Content

[0003] (1) Technical issues to be resolved

[0004] To address the problems of inconvenient operation, low efficiency, and unsuitability for continuous chamfering operations in existing chamfering devices.

[0005] (2) Technical solution

[0006] The technical solution of this utility model is as follows: a double-headed chamfering device for mold steel, including a workbench and a mounting frame installed on the outside of the workbench. Fixed seats are symmetrically arranged on both sides of the workbench. A first mounting seat is hinged above the fixed seats. A first chamfering machine is installed on the upper surface of the first mounting seat. A lifting cylinder is installed on the side of the mounting frame near the fixed seats, and the output end of the lifting cylinder is connected to the fixed seats.

[0007] Preferably, by retracting the lifting cylinder, the fixed seat is moved to the bottom of the workbench platform, making it easier to send the steel to the top of the workbench for continuous chamfering. Then, two sets of first chamfering machines can chamfer the edges of the steel plates on the workbench. At the same time, the lifting cylinder is activated to move the first chamfering machines vertically, which can chamfer steel plates of different thicknesses. The operation is simple and improves the efficiency of steel processing.

[0008] Furthermore, slide rails are symmetrically welded to the surface of the mounting bracket, and a fixed slider is connected to the surface of the mounting base near the slide rail. The mounting base slides on the surface of the slide rail via the slider, which improves the stability of the movement of the mounting base.

[0009] Furthermore, a fixing block is fixedly connected to one side of the surface of the first mounting base, and a limit block is slidably connected inside the fixing block. An arc-shaped groove is opened on the side of the fixing base surface near the limit block, and a scale mark is provided on the side of the fixing base surface near the arc-shaped groove. This allows the angle of the first chamfering machine to be adjusted, improving the flexibility of the first chamfering machine and meeting different processing needs of steel.

[0010] Furthermore, the surface of the fixing block is rotatably connected to the locking bolt, and the limiting block is threadedly connected to the surface of the locking bolt, which can lock the position of the first chamfering machine after adjustment.

[0011] Furthermore, a support is provided between the two sets of first chamfering machines, and the support is fixed on one side of the worktable. A U-shaped baffle is fixedly connected to the top of the support, and guide rails are symmetrically fixed to the top of the mounting frame, which facilitates the transport of the processed steel to the top of the worktable through the guide rails, thereby improving the convenience of loading and unloading the steel.

[0012] Furthermore, an optical axis is fixedly connected to the surface of the bracket, and a second mounting base is slidably connected to the surface of the optical axis. A second chamfering machine is installed above the second mounting base at an angle. By starting the second chamfering machine and moving it along the optical axis, the horizontal bottom edge of the steel plate can be automatically chamfered, realizing simultaneous processing of multiple sides of the steel plate.

[0013] Furthermore, a waste box is fixedly connected to the side of the workbench near the baffle. The cross-section of the inner groove of the waste box is trapezoidal, and a cleaning door is hinged to the bottom of the outer surface of the waste box, which can collect the debris generated during the chamfering process.

[0014] (3) Beneficial effects

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows: by retracting the lifting cylinder, the first chamfering machine is moved to the bottom of the worktable platform, which facilitates the transport of steel to the top of the worktable via the guide rail, improving the convenience of loading and unloading steel and facilitating continuous chamfering operations on steel. The first chamfering machines on both sides process the two sides of the steel plate, and the lifting cylinder drives the first chamfering machine to move vertically, realizing automatic chamfering of the steel plate and improving processing efficiency. At the same time, the second chamfering machine is started to move along the optical axis, which can automatically chamfer the horizontal bottom edge of the steel plate, realizing multi-side synchronous processing of the steel plate. The first mounting base cooperates with the fixed base to allow the limiting block to slide inside the arc groove, which can adjust the angle of the first chamfering machine to meet different processing needs of steel.

Detailed Implementation

[0023] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0024] Example 1:

[0025] See Figure 1-6 This utility model provides an embodiment including a workbench 1 and a mounting frame 2 installed on the outside of the workbench 1. Fixed seats 9 are symmetrically arranged on both sides of the workbench 1. A first mounting seat 10 is hinged above the fixed seat 9.

A lifting cylinder 8 is installed on the side of the mounting frame 2 near the fixed seat 9, and the output end of the lifting cylinder 8 is connected to the fixed seat 9. By starting the lifting cylinder 8 to retract, the fixed seat 9 is moved to the lower part of the workbench 1 platform, which facilitates the delivery of steel to the upper part of the workbench 1, and facilitates continuous chamfering of the steel. Then, the two sets of first chamfering machines 6 can chamfer the corners of the steel plates on the workbench 1. At the same time, the lifting cylinder 8 is started to drive the first chamfering machine 6 to move vertically, which can chamfer steel plates of different thicknesses. The operation is simple and improves the efficiency of steel processing.

[0026] The surface of the mounting bracket 2 is symmetrically welded with slide rails 12. A slider 13 is fixedly connected to the surface of the mounting base 9 near the slide rails 12, and the mounting base 9 slides on the surface of the slide rails 12 via the slider 13. When the lifting cylinder 8 is activated to move the mounting base 9 vertically, it will cause the slider 13 to move on the surface of the slide rails 12, improving the stability of the movement of the mounting base 9. A fixing block 14 is fixedly connected to one side of the surface of the first mounting base 10. A limit block 16 is slidably connected inside the fixing block 14. An arc-shaped groove 11 is formed on the surface of the mounting base 9 near the limit block 16. A locking bolt 15 is rotatably connected to the surface of the fixing block 14, and the limit block 16 is threaded onto the surface of the locking bolt 15. By rotating the first mounting base 10, the limit block 16 slides inside the arc-shaped groove 11, which can adjust the angle of the first chamfering machine 6, improving... The first chamfering machine 6 is flexible in use and can meet different processing needs of steel. The fixed base 9 has scale markings on the side near the arc groove 11, which makes the adjustment visible. By rotating the locking bolt 15, the limit block 16 is pressed against the inside of the arc groove 11, which can lock the position of the first chamfering machine 6 after adjustment. A bracket 3 is set between the two sets of first chamfering machines 6, and the bracket 3 is fixed to one side of the worktable 1. The top of the bracket 3 is fixedly connected to a U-shaped baffle 4. The top of the mounting frame 2 is symmetrically fixed with guide rails 5. By setting the guide rails 5, it is easy to transport the processed steel to the top of the worktable 1, improve the convenience of loading and unloading steel, and facilitate continuous chamfering operation of steel. The baffle 4 can guide the processed edge of the steel plate, which facilitates the quick alignment of the plate and improves the processing accuracy.

[0027] Example 2:

[0028] Please see Figure 1-6 In this embodiment, an optical axis 17 is fixedly connected to the surface of the bracket 3, and a second mounting base 19 is slidably connected to the surface of the optical axis 17. A second chamfering machine 18 is installed above the second mounting base 19 and is inclined. The second chamfering machine 18 can chamfer the transverse edge of the plate. A drive mechanism is installed inside the second mounting base 19, which can drive the second mounting base 19 to slide on the surface of the optical axis 17. By starting the second chamfering machine 18, the chamfering cutter is driven to rotate and move along the optical axis 17 parallel to the steel plate, so as to realize the automatic chamfering of the transverse bottom edge of the steel plate and improve the processing efficiency of the mold steel.

[0029] A waste box 7 is fixedly connected to the side of the workbench 1 near the baffle 4. The inner groove of the waste box 7 has a trapezoidal cross-section. A cleaning door is hinged to the bottom of the outer surface of the waste box 7. The waste box 7 is located below the second chamfering machine 18 and the first chamfering machine 6. It can collect the debris generated during the chamfering process. The collected debris can be easily processed through the cleaning door on the waste box 7.

[0030] Through the above steps, by retracting the lifting cylinder 8, the first chamfering machine 6 is moved to the lower part of the worktable 1 platform, which facilitates the transport of steel materials to the upper part of the worktable 1 via the guide rail 5, improving the convenience of loading and unloading steel materials and facilitating continuous chamfering operations on steel materials. The first chamfering machines 6 on both sides process the two sides of the steel plate, and in conjunction with the lifting cylinder 8, the first chamfering machine 6 moves vertically to realize automatic chamfering processing of the steel plate, improving processing efficiency. At the same time, the second chamfering machine 18 is started and moves along the optical axis 17, which can automatically chamfer the horizontal bottom edge of the steel plate, realizing multi-side synchronous processing of the steel plate. The first mounting base 10, in conjunction with the fixed base 9, allows the limiting block 16 to slide inside the arc groove 11, which can adjust the angle of the first chamfering machine 6 to meet different processing requirements of steel materials.
