Description

TECHNICAL FIELD

[0001] The utility model belongs to numerical control blade processing technical field, specifically related to a numerical control blade processing stamping device. BACKGROUND

[0002] In modern manufacturing, numerical control blade as the key component of numerical control machine tool, its quality and precision directly affect the quality and efficiency of processing products. The processing technology of numerical control blade is various, and stamping is an important link to shape its shape.

[0003] However, in the traditional numerical control blade stamping device, there are a series of problems to be solved. First of all, the imperfect lubrication system is a prominent problem. Due to the lack of effective lubrication measures, the die is prone to excessive wear in the frequent stamping process, which not only shortens the service life of the die, but also may cause the stamping precision to decrease, affecting the quality consistency of numerical control blade.

[0004] Secondly, the demolding process often troubles the production process. After stamping, the blade sometimes adheres tightly to the surface of the die, which is difficult to take out smoothly. This not only increases the complexity and time cost of operation, but also may cause damage to the blade in the process of forced demolding, reducing the product qualification rate.

[0005] Therefore, we propose a numerical control blade processing stamping device, which can not only realize the lubrication of the forming groove and improve the service life of the die, but also can quickly demold and improve the working efficiency. CONTENT OF THE NEW UTILITY MODEL

[0006] The utility model aims at providing a numerical control blade processing stamping device, which can not only realize the lubrication of the forming groove and improve the service life of the die, but also can quickly demold and improve the working efficiency.

[0007] The technical scheme adopted by the utility model is as follows:

[0008] A numerical control blade processing stamping device, comprising a U-shaped frame, a lower die is arranged at one end of the U-shaped frame, two symmetrically arranged L-shaped oil storage grooves, two symmetrically arranged limiting grooves and a forming groove are arranged on the lower die, the two L-shaped oil storage grooves are communicated with the forming groove, and an extrusion assembly is arranged in the two L-shaped oil storage grooves, a connecting plate is arranged on the extrusion assembly, and a second meshing tooth is arranged on one side of the connecting plate.

[0009] The other end of the U-shaped frame is provided with a hydraulic assembly, the hydraulic assembly is provided with a mounting plate, two limiting plates matched with the limiting grooves and an upper die are arranged at the bottom of the mounting plate, a first meshing tooth is arranged on one side of the limiting plate, and a gear connected with the U-shaped frame is arranged between the first meshing tooth and the second meshing tooth.

[0010] Further, the L-shaped oil storage tank is divided into a first tank body and a second tank body, the diameter of the first tank body is larger than the diameter of the second tank body.

[0011] Further, the extrusion assembly comprises a piston plate arranged in the first tank body, and a movable plate is arranged on the top of the piston plate, and the top of the movable plate is connected with the connecting plate.

[0012] Further, an oil inlet pipe communicated with the L-shaped oil storage tank is arranged on the lower die.

[0013] Further, a sealing block is arranged in the first tank body, and a through groove for moving the connecting plate is formed in the sealing block.

[0014] Further, the hydraulic assembly comprises a hydraulic cylinder arranged on the U-shaped frame, and the telescopic end of the hydraulic cylinder is connected with the mounting plate.

[0015] The technical effects of the utility model are as follows:

[0016] Before the stamping operation, first of all, two L-shaped oil tank is filled with sufficient lubricating oil, when starting stamping process, the hydraulic assembly is instructed to start working, its movable end stretches and pushes the mounting plate to move down. The downward movement of the mounting plate drives the upper die to approach the lower die in a stable and vertical path. When the upper die and the lower die gradually approach and finally contact each other, they work together to stamp the material placed between them to form the required CNC blade shape, and at the same time, the downward movement of the mounting plate also drives the limiting plate connected thereto to move downward synchronously. With the downward movement of the limiting plate, the first meshing tooth arranged on one side of the limiting plate is in meshing state with the gear. Due to the continuous downward movement of the limiting plate, the force applied by the limiting plate to the gear makes the gear start to rotate clockwise around its axis, and the clockwise rotation of the gear drives the second meshing tooth on the other side to move upward. Since the second meshing tooth is fixedly connected with the connecting plate, and the connecting plate is connected with the extrusion assembly, the upward movement of the second meshing tooth drives the connecting plate and the extrusion assembly to move upward as a whole. When the extrusion assembly moves upward, it blocks and extrudes the lubricating oil in the L-shaped oil tank, so that the lubricating oil is temporarily restricted in the L-shaped oil tank and cannot enter the forming groove. Once the stamping process is completed, the hydraulic assembly receives the retraction instruction, and its movable end retracts and drives the mounting plate to move upward. The upward movement of the mounting plate separates the upper die from the lower die, completing a stamping action. During the upward movement of the mounting plate, the limiting plate also moves upward. At this time, due to the upward movement of the limiting plate, the force acting on the gear changes, and the gear starts to rotate counterclockwise. The counterclockwise rotation of the gear drives the second meshing tooth and the connecting plate connected thereto to move downward. The downward movement of the connecting plate drives the extrusion assembly to move downward in the L-shaped oil tank. With the downward movement of the extrusion assembly, the space in the L-shaped oil tank is further compressed, and the internal pressure rapidly increases. Under the action of pressure, the originally blocked lubricating oil breaks through the restriction and smoothly flows from the L-shaped oil tank into the forming groove. The lubricating oil fully wets the surface of the mold in the forming groove, providing good lubrication conditions for the next stamping, reducing the friction and wear between the molds. In addition, before the lubricating oil enters the forming groove, compressed gas can be introduced into the forming groove through the pre-set gas pressure device. The pressure of the gas acts on the blade that may be adhered to the surface of the mold after stamping, quickly pushing the blade out of the mold, greatly facilitating the removal operation of the blade and significantly improving the production efficiency. The whole working process is repeated, and the continuous lubrication of the forming groove and the easy removal of the blade are realized stably and efficiently. BRIEF DESCRIPTION OF DRAWINGS

DETAILED DESCRIPTION

[0023] In order to make the purpose and advantages of the utility model more clear and obvious, the utility model is specifically described below in combination with examples. It should be understood that the following text is only used to describe one or several specific embodiments of the utility model, and does not strictly limit the protection scope specifically requested by the utility model.

[0024] As Figures 1-4 indicated, the technical scheme adopted by the utility model is specifically as follows: a numerical control blade machining stamping device, comprising a U-shaped frame 1, the U-shaped frame 1 is provided with a lower mold 2 at one end, the lower mold 2 is provided with two symmetrically arranged L-shaped oil storage grooves 3, two symmetrically arranged limiting grooves 4 and a forming groove 5, the two L-shaped oil storage grooves 3 are communicated with the forming groove 5, and the two L-shaped oil storage grooves 3 are provided with extrusion assemblies inside, the extrusion assemblies are provided with connecting plates 6, and the connecting plates 6 are provided with second meshing teeth 7 on one side.

[0025] The other end of the U-shaped frame 1 is provided with a hydraulic assembly, the hydraulic assembly is provided with a mounting plate 8, the bottom of the mounting plate 8 is provided with two limiting plates 9 matched with the limiting grooves 4 and an upper mold 10, the limiting plates 9 are provided with first meshing teeth 11 on one side, and the first meshing teeth 11 and the second meshing teeth 7 are provided with a gear 12 connected with the U-shaped frame 1.

[0026] Among them, the L-shaped oil storage groove 3 is divided into a first groove body 13 and a second groove body 14, the diameter of the first groove body 13 is greater than that of the second groove body 14, and the setting has the following advantages:

[0027] 1, pressure accumulation: when the extrusion assembly moves in the L-shaped oil storage groove 3, because the diameter of the first groove body 13 is relatively large and the space is relatively large, the pressure increases relatively slowly at the initial stage of movement. When the lubricating oil is extruded into the second groove body 14 with a smaller diameter, the space suddenly becomes smaller, and the pressure can be accumulated faster, so that the lubricating oil can be pushed into the forming groove 5 more effectively.

[0028] 2. More lubricating oil can be stored in the first groove body 13 with a larger diameter, reducing the frequency of adding lubricating oil and improving work efficiency.

[0029] 3. Buffering effect: when the extrusion assembly returns, the larger space of the first groove body 13 can play a certain buffering effect, avoiding the lubricating oil from flowing back too fast or too violently, which helps to maintain the stability of the system.

[0030] 4. Precise control of oil output: due to the smaller diameter of the second groove body 14, the flow of lubricating oil can be more precisely controlled, making the amount of lubricating oil entering the forming groove 5 more stable and appropriate, avoiding too much or too little lubricating oil entering.

[0031] 5. Improve lubrication effect: the difference in diameter can make the lubricating oil have a certain spraying effect when entering the forming groove 5, which can be more evenly distributed in the forming groove 5, improving the comprehensiveness and effectiveness of lubrication.

[0032] At the same time, the extrusion assembly includes a piston plate 15 arranged inside the first groove body 13, and the piston plate 15 is provided with a movable plate 16 on the top, and the movable plate 16 is connected with the connecting plate 6, and the movable plate 16 is moved by the connecting plate 6, so that the piston plate 15 moves, realizing the extrusion and recovery of lubricating oil.

[0033] The lower die 2 is provided with an oil inlet pipe 17 communicating with the L-shaped oil storage groove 3, and the lubricating oil enters the inside through the oil inlet pipe 17.

[0034] The first groove body 13 is provided with a sealing block 18, and the sealing block 18 is provided with a through groove for moving the connecting plate 6, which can ensure that the first groove body 13 is in a sealed state and will not leak.

[0035] It should be noted that when the forming groove 5 is punched, the blade is punched into the desired shape, at which time the forming groove 5 and the L-shaped oil storage groove 3 are in a sealed state, so when the piston plate 15 moves and exerts pressure, air pressure will be generated, which will easily make the blade inside the forming groove 5 move, and it will be easy to take out. When the blade moves, the forming groove 5 is not in a sealed state with the L-shaped oil storage groove 3, and the lubricating oil is sprayed to lubricate the inner wall of the forming groove 5. During this punching, due to the suction effect of the piston plate 15, the lubricating oil is quickly sucked back into the L-shaped oil storage groove 3 for next use.

[0036] The hydraulic assembly includes a hydraulic cylinder 19 arranged on the U-shaped frame 1, and the hydraulic cylinder 19 is connected with the mounting plate 8 at the telescopic end, and the mounting plate 8 is moved up and down by the hydraulic cylinder 19.

[0037] The working principle of the utility model is as follows: before the stamping operation, the two L-shaped oil storage tanks 3 are filled with sufficient lubricating oil, when the stamping process is started, the hydraulic assembly is instructed to work, the movable end stretches and pushes the mounting plate 8 to move downward. The downward movement of the mounting plate 8 drives the upper die 10 to approach the lower die 2 in a stable and vertical path. When the upper die 10 and the lower die 2 gradually approach and finally contact each other, they work together to stamp the material placed between them, thereby shaping the required CNC blade shape, at the same time, the downward movement of the mounting plate 8 also drives the limiting plate 9 connected thereto to move downward synchronously. With the downward movement of the limiting plate 9, the first meshing tooth 11 arranged on one side of the limiting plate 9 is in meshing state with the gear 12. Due to the continuous downward movement of the limiting plate 9, the force exerted by the limiting plate 9 on the gear 12 makes the gear 12 start to rotate clockwise around its axis, the clockwise rotation of the gear 12 in turn drives the second meshing tooth 7 on the other side to move upward. Since the second meshing tooth 7 is fixedly connected with the connecting plate 6, and the connecting plate 6 is connected with the extrusion assembly, the upward movement of the second meshing tooth 7 drives the connecting plate 6 and the extrusion assembly to move upward as a whole, when the extrusion assembly moves upward, it blocks and extrudes the lubricating oil in the L-shaped oil storage tank 3, so that the lubricating oil is temporarily restricted in the L-shaped oil storage tank 3 and cannot enter the forming groove 5, once the stamping process is completed, the hydraulic assembly receives the retraction instruction, the movable end retracts and drives the mounting plate 8 to move upward. The upward movement of the mounting plate 8 separates the upper die 10 from the lower die 2, completing a stamping action, in the process of upward movement of the mounting plate 8, the limiting plate 9 also moves upward. At this time, due to the upward movement of the limiting plate 9, the force acting on the gear 12 changes, the gear 12 starts to rotate counterclockwise, the counterclockwise rotation of the gear 12 drives the second meshing tooth 7 and the connecting plate 6 connected thereto to move downward. The downward movement of the connecting plate 6 pushes the extrusion assembly to move downward in the L-shaped oil storage tank 3, with the downward movement of the extrusion assembly, the space in the L-shaped oil storage tank 3 is further compressed, and the internal pressure rapidly increases. Under the action of pressure, the originally blocked lubricating oil breaks through the restriction and smoothly flows from the L-shaped oil storage tank 3 into the forming groove 5. The lubricating oil fully wets the mold surface in the forming groove 5, providing good lubrication conditions for the next stamping, reducing the friction and wear between the molds, in addition, before the lubricating oil enters the forming groove 5, compressed gas can also be introduced into the forming groove 5 through the pre-set gas pressure device. The pressure of the gas acts on the blade that may be adhered to the mold surface after stamping, quickly pushes the blade out of the mold, greatly facilitates the taking out operation of the blade, significantly improves the production efficiency, the whole working process is repeated, and the continuous lubrication of the forming groove 5 and the easy taking out of the blade are stably and efficiently realized.

[0038] The above only is the preferred embodiment of the utility model, it should be pointed out, for ordinary skilled person in the art, without departing from the principle of the utility model, can make a number of improvements and refinements, these improvements and refinements also should be considered the protection scope of the utility model.The structure, device and operating method not specifically described and explained in the utility model, are implemented according to conventional means in the art, unless specifically described and limited.
