Description

Technical Field

[0001] The invention belongs to the technical field of punching machines, and in particular relates to a numerically controlled punching machine for shutters. Background Art

[0002] CNC punching machines play an important role in the processing of complex components such as shutters. There are many processing methods for CNC punching machines, such as single punching, continuous punching in multiple directions, single forming, continuous punching in the same direction, nibbling, array forming and continuous forming. These different processing methods enable CNC punching machines to complete processing tasks of various complex shapes and sizes, including punching and forming of shutters.

[0003] At present, when using a punch press to process Venetian blinds, since the Venetian blinds have different shapes and different stamping dies are required to punch out different holes on the Venetian blinds, different stamping dies need to be replaced when processing the Venetian blinds. However, during the replacement of the stamping dies, it is necessary to ensure that the stamping dies are directly under the hydraulic head. If the stamping dies are not directly under the hydraulic head, the pressure applied by the hydraulic equipment to the stamping dies will be uneven, resulting in uneven pressure when the stamping dies stamp the Venetian blinds, thereby affecting the quality of the produced Venetian blinds. Based on this, a CNC punch press for Venetian blinds is proposed. Summary of the invention

[0007] As a further optimization solution of the present invention, a fixing rod is fixedly connected to the top of the mounting plate, a sleeve is fixedly connected to the bottom of the pressure plate, and the fixing rod is sealingly and slidably connected to the inner surface of the sleeve.

[0008] As a further optimization solution of the present invention, the pressure plate is located below the hydraulic head, and the fixing fixture is adapted to the fixing groove.

[0009] As a further optimization scheme of the present invention, an air inlet hole connected to the interior of the sleeve is opened on the top of the pressure plate, and an exhaust pipe is fixedly connected to the outer surface of the sleeve, and the exhaust pipe is connected to the interior of the stamping plate.

[0010] As a further optimization scheme of the present invention, the positioning mechanism also includes a slide groove opened at the bottom of the mounting column, a return spring is fixedly connected in the slide groove, the positioning rod is slidably connected to the slide groove, and the return spring is fixedly connected to the positioning rod.

[0011] As a further optimization solution of the present invention, the bottom of the positioning rod is inclined, the positioning groove is inclined, and the positioning rod is matched with the positioning groove.

[0012] As a further optimization scheme of the present invention, the limiting mechanism includes a connecting rod fixedly connected to the outer surface of the hydraulic head, the outer surface of the hydraulic equipment is fixedly connected to a liquid tank, a slide plate is sealingly and slidingly connected inside the liquid tank, the top of the slide plate is fixedly connected to the connecting rod, a sealing plate is sealingly and slidingly connected inside the liquid tank, and one side of the sealing plate is fixedly connected to the limiting rod.

[0013] As a further optimization solution of the present invention, the limiting rod passes through the liquid tank and is slidably connected to the liquid tank, and the limiting rod is located between the mounting column and the fixing plate.

[0014] As a further optimization scheme of the present invention, the hydraulic equipment is installed on the top of the electrical box, the hydraulic head is installed on the output end of the hydraulic equipment, the support seat is fixedly connected to the top of the electrical box, a guide wheel is installed on the top of the support seat, the outer surface of the guide wheel is in contact with the inner surface of the turntable, and a handle is installed on the outer surface of the turntable.

[0015] The beneficial effects of the present invention are: 1. The present invention provides a positioning mechanism. When different stamping mechanisms are used to stamp the shutters, the positioning rod will slide in the groove by holding the handle and turning the turntable to make the corresponding stamping mechanism reach the bottom of the hydraulic head. When the positioning rod slides onto the slope block, the inclination of the slope block will cause the positioning rod to slide into the slide groove to squeeze the return spring. When the positioning rod is detached from the highest point of the slope block, the positioning rod will enter the positioning groove under the action of the return spring. At this time, the positioning of the stamping mechanism is completed, so that the stamping mechanism is directly below the hydraulic head, ensuring the uniformity of the pressure applied by the hydraulic equipment to the stamping mechanism, thereby ensuring the quality of the stamping of the shutters.

[0016] 2. The present invention sets a stamping mechanism. During the process of the stamping mechanism stamping the shutters, the downward movement of the pressure plate will cause the fixing rod to slide into the sleeve relative to the sleeve, so that the gas in the sleeve is discharged into the stamping plate through the exhaust pipe, and blown to the stamping part of the shutter through the stamping plate, so that part of the material removed by the stamping of the shutter can be quickly detached from the stamping mechanism, and the stamping mechanism can be cooled to reduce the heat generated by the deformation of the material when stamping the shutters, thereby reducing the thermal stress caused by the temperature on the stamping mechanism and the shutters, improving the processing efficiency, and providing good protection for the stamping mechanism and the shutters.

[0017] 3. The present invention sets a limiting mechanism. When the hydraulic head drives the stamping mechanism to work and the stamping mechanism is not performing stamping processing on the shutters, the downward movement of the hydraulic head will cause the connecting rod to push the slide plate to slide into the liquid tank, so that the liquid in the liquid tank pushes the sealing plate to slide outward, and then the limiting rod reaches the left side of the positioning rod, thereby effectively limiting the positioning rod and preventing the positioning rod from detaching from the positioning groove due to excessive pressure during stamping, resulting in the pressure not being at the center of the stamping when stamping the shutters, thereby ensuring the uniformity of the pressure during stamping and ensuring the stamping quality.

The sleeve 1004 is fixedly connected, the fixing rod 1003 is sealed and slidably connected to the inner surface of the sleeve 1004, the bottom of the pressure plate 1005 is fixedly connected to the mounting plate 1001 through the damping rod 1012, the connecting spring 1010 is sleeved on the outer surface of the damping rod 1012, the bottom of the pressure plate 1005 is fixedly connected to the upper mold 1007 at the position facing the lower mold 1002, the bottom of the upper mold 1007 is fixedly connected to the stamping plate 1008 adapted to the stamping hole 1006, the stamping plate 1008 is set to a hollow form, and the bottom of the stamping plate 1008 is fixedly connected to a plurality of reinforcing ribs to ensure that the stamping plate 1 008 has rigidity, an air inlet hole 1013 connected to the inside of the sleeve 1004 is opened on the top of the pressure plate 1005, and a one-way valve is installed in the air inlet hole 1013, so that the sleeve 1004 can only draw outside air through the air inlet hole 1013, and the outer surface of the sleeve 1004 is fixedly connected to an exhaust pipe 1014, and a one-way valve is installed in the exhaust pipe 1014, so that the gas in the sleeve 1004 can only be discharged through the exhaust pipe 1014, and the exhaust pipe 1014 is connected to the inside of the stamping plate 1008, and fixing grooves 1009 are opened on both sides of the top of the mounting plate 1001, and the fixing clamps 9 are adapted to the fixing grooves 1009.

[0022] When in use, hold the handle 7 and rotate the turntable 6 to rotate the corresponding stamping mechanism 10 to the bottom of the hydraulic head 3. When the stamping mechanism 10 reaches the bottom of the hydraulic head 3, the shutter to be stamped is placed on the top of the lower mold 1002, and the punching part of the shutter is opposite to the punching hole 1006. At this time, the hydraulic equipment 2 can be started to move the hydraulic head 3 downward, contact the pressure plate 1005 and push the pressure plate 1005 to move downward, so that the upper mold 1007 drives the stamping plate 1008 to move downward, and then the stamping plate 1008 cooperates with the punching hole 1006 to punch the stamping part of the shutter. In this process, the downward movement of the pressure plate 1005 will cause the sleeve 1004 to slide downward along the outer surface of the fixed rod 1003, while compressing the connecting spring 1010 and the damping rod 1012; In this process, since the sleeve 1004 slides downward along the outer surface of the fixing rod 1003, the gas in the sleeve 1004 will be discharged into the stamping plate 1008 through the exhaust pipe 1014, and blown to the stamping part of the shutter through the stamping plate 1008, so that the part of the material removed by the stamping of the shutter can be quickly separated from the lower mold 1002, and the stamping mechanism 10 can be cooled down, reducing the heat generated by the deformation of the material when stamping the shutter, thereby reducing the thermal stress caused by the temperature on the stamping mechanism 10 and the shutter, improving the processing efficiency, and providing good protection for the stamping mechanism 10 and the shutter; After the stamping plate 1008 passes through the stamping hole 1006, the hydraulic equipment 2 is started to move the hydraulic head 3 upward. At this time, the pressure plate 1005 will move upward under the action of the connecting spring 1010, so that the stamping plate 1008 is withdrawn from the stamping hole 1006 until the pressure plate 1005 is reset. Then the shutter after stamping can be removed. In this process, due to the reset of the pressure plate 1005, the sleeve 1004 will slide upward along the outer surface of the fixed rod 1003, so that the sleeve 1004 draws outside air into the sleeve 1004 through the air inlet hole 1013 for the next stamping use.

[0023] like Figure 2 , Figure 5 , Figure 6 , Figure 8 , Fig. 9 , Fig.10 and Fig.11As shown, the shutter CNC punching machine also includes: a positioning mechanism 11 installed on the top of the support seat 4, the positioning mechanism 11 includes a fixed plate 1101 fixedly connected to the top of the support seat 4, a groove 1102 is opened on the top of the fixed plate 1101, a slope block 1103 is fixedly connected in the groove 1102, the slope block 1103 is inclined, the groove 1102 is located at the highest side of the slope block 1103 and a positioning groove 1104 is opened, and a positioning rod 1107 is fitted in the positioning groove 1104. The bottom of the rod 1107 is inclined, the positioning groove 1104 is inclined, the positioning rod 1107 is adapted to the positioning groove 1104, and when the positioning rod 1107 enters the positioning groove 1104, the stamping mechanism 10 is positioned. The positioning mechanism 11 also includes a slide groove 1105 opened at the bottom of the mounting column 1011, and a return spring 1106 is fixedly connected in the slide groove 1105. The positioning rod 1107 is slidably connected to the slide groove 1105, and the return spring 1106 is fixedly connected to the positioning rod 1107.

[0024] When in use, in the process of moving the corresponding stamping mechanism 10 to the bottom of the hydraulic head 3, when the turntable 6 rotates, it will drive the positioning rod 1107 to slide in the groove 1102 through the mounting column 1011. When the positioning rod 1107 slides onto the slope block 1103, the inclination of the slope block 1103 will cause the positioning rod 1107 to slide into the slide groove 1105 to squeeze the return spring 1106. When the positioning rod 1107 is disengaged from the highest point of the slope block 1103, the positioning rod 1107 will enter the positioning groove 1104 under the action of the return spring 1106, and then push the turntable 6 in the opposite direction so that the positioning rod 1107 is pressed against the slope block 1103. At this time, the positioning of the stamping mechanism 10 is completed, so that the stamping mechanism 10 is directly below the hydraulic head 3, ensuring the uniformity of the pressure applied by the hydraulic equipment 2 to the stamping mechanism 10, thereby ensuring the quality of the stamping of the shutters.

[0025] like Figure 5 , Figure 7 , Fig. 9 , Fig.10 and Fig.11As shown, the shutter CNC punching machine also includes: a limiting mechanism 12 installed on the hydraulic head 3, the limiting mechanism 12 is used to limit the positioning mechanism 11, the limiting mechanism 12 includes a connecting rod 1201 fixedly connected to the outer surface of the hydraulic head 3, the outer surface of the hydraulic equipment 2 is fixedly connected to a liquid tank 1203, a slide plate 1202 is sealingly and slidably connected inside the liquid tank 1203, the top of the slide plate 1202 is fixedly connected to the connecting rod 1201, a sealing plate 1204 is sealingly and slidably connected inside the liquid tank 1203, the liquid tank 1203 is located in a space between the sealing plate 1204 and the slide plate 1202 and is filled with liquid, one side of the sealing plate 1204 is fixedly connected to a limiting rod 1205, the limiting rod 1205 passes through the liquid tank 1203 and is slidably connected to the liquid tank 1203, and the limiting rod 1205 is located between the mounting column 1011 and the fixed disk 1101.

[0026] When in use, when the hydraulic head 3 starts to move downward, the downward movement of the hydraulic head 3 will drive the connecting rod 1201 to move downward, so that the slide plate 1202 slides downward in the liquid tank 1203, squeezing the liquid in the liquid tank 1203, and then the sealing plate 1204 pushes the limiting rod 1205 to move outward along the inner surface of the liquid tank 1203, so that the limiting rod 1205 reaches the left side of the positioning rod 1107, realizing effective positioning of the positioning rod 1107, avoiding the positioning rod 1107 from being separated from the positioning groove 1104 due to excessive pressure during stamping, resulting in the pressure not being at the center of the stamping when stamping the shutter, thereby ensuring the uniformity of the pressure during stamping and ensuring the stamping quality; When the hydraulic head 3 moves upward, the hydraulic head 3 will drive the slide plate 1202 to slide upward in the liquid tank 1203 through the connecting rod 1201, extract the liquid in the liquid tank 1203, and then make the sealing plate 1204 slide inward along the inner surface of the liquid tank 1203, so that the limit rod 1205 moves inward and is pulled out of the left side of the positioning rod 1107, thereby facilitating the replacement of different stamping mechanisms 10.

[0027] The specific working principle of the present invention is as follows: Hold the handle 7 and rotate the turntable 6 to rotate the corresponding punching mechanism 10 to the position directly below the hydraulic head 3. When the punching mechanism 10 reaches the position directly below the hydraulic head 3; When the corresponding stamping mechanism 10 is moved to the bottom of the hydraulic head 3, the rotating disk 6 rotates, and the positioning rod 1107 is driven to slide in the groove 1102 through the mounting column 1011. When the positioning rod 1107 slides onto the slope block 1103, the inclination of the slope block 1103 will cause the positioning rod 1107 to slide into the slide groove 1105 to squeeze the return spring 1106. When the positioning rod 1107 is disengaged from the highest point of the slope block 1103, the positioning rod 1107 will enter the positioning groove 1104 under the action of the return spring 1106, and then push the rotating disk 6 in the reverse direction so that the positioning rod 1107 and the slope block 1103 are pressed tightly. At this time, the positioning of the stamping mechanism 10 is completed, so that the stamping mechanism 10 is directly below the hydraulic head 3, ensuring the uniformity of the pressure applied by the hydraulic equipment 2 to the stamping mechanism 10, thereby ensuring the quality of the stamping of the shutters. At this time, the shutter that needs to be punched is placed on the top of the lower mold 1002, and the punching part of the shutter is opposite to the punching hole 1006. At this time, the hydraulic equipment 2 can be started to make the hydraulic head 3 move downward, contact with the pressure plate 1005 and push the pressure plate 1005 to move downward, so that the upper mold 1007 drives the punching plate 1008 to move downward, and then the punching plate 1008 cooperates with the punching hole 1006 to punch the punching part of the shutter. In this process, the downward movement of the pressure plate 1005 will cause the sleeve 1004 to slide downward along the outer surface of the fixed rod 1003, and compress the connecting spring 1010 and the damping rod 1012 at the same time; When the hydraulic head 3 starts to move downward, the downward movement of the hydraulic head 3 will drive the connecting rod 1201 to move downward, so that the sliding plate 1202 slides downward in the liquid tank 1203, squeezing the liquid in the liquid tank 1203, and then the sealing plate 1204 pushes the limiting rod 1205 to move outward along the inner surface of the liquid tank 1203, so that the limiting rod 1205 reaches the left side of the positioning rod 1107, realizing effective limiting of the positioning rod 1107, ensuring that when stamping the shutters, the stamping mechanism 10 is always directly below the hydraulic head 3, avoiding the positioning rod 1107 from being separated from the positioning groove 1104 due to excessive pressure during stamping, resulting in the pressure not being at the center of the stamping when stamping the shutters, thereby ensuring the uniformity of the pressure during stamping and ensuring the stamping quality; In addition, during the stamping process, since the sleeve 1004 slides downward along the outer surface of the fixing rod 1003, the gas in the sleeve 1004 will be discharged into the stamping plate 1008 through the exhaust pipe 1014, and blown to the stamping part of the shutter through the stamping plate 1008, so that the part of the material removed by the stamping of the shutter can be quickly separated from the lower mold 1002, and the stamping mechanism 10 can be cooled down, reducing the heat generated by the deformation of the material when stamping the shutter, thereby reducing the thermal stress caused by the temperature on the stamping mechanism 10 and the shutter, improving the processing efficiency, and providing good protection for the stamping mechanism 10 and the shutter; After the punching plate 1008 passes through the punching hole 1006, the hydraulic device 2 is started to move the hydraulic head 3 upward. At this time, the pressure plate 1005 will move upward under the action of the connecting spring 1010, so that the punching plate 1008 is withdrawn from the punching hole 1006 until the pressure plate 1005 is reset. Then the shutter after the punching process can be removed. In this process, due to the reset of the pressure plate 1005, the sleeve 1004 will slide upward along the outer surface of the fixed rod 1003, so that the sleeve 1004 draws outside air into the sleeve 1004 through the air inlet 1013 for the next punching use. At the same time, the hydraulic head 3 will drive the slide plate 1202 to slide upward in the liquid tank 1203 through the connecting rod 1201, extract the liquid in the liquid tank 1203, and then make the sealing plate 1204 slide inward along the inner surface of the liquid tank 1203, so that the limit rod 1205 moves inward and pulls out from the left side of the positioning rod 1107, thereby facilitating the replacement of different stamping mechanisms 10.

[0028] The above-mentioned embodiments only express several implementation methods of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the present invention. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, which all belong to the protection scope of the present invention.
