Description

Technical Field

[0001] The utility model relates to the field of stamping production, in particular to a stamping structure of a horizontal stamping and forming device. Background Art

[0002] Stamping processing is a production technology that relies on the power of conventional or special stamping equipment to directly deform a sheet metal under the action of a deforming force in a mold, thereby obtaining product parts with a certain shape, size, and performance.

[0003] Currently, when the existing stamping equipment stamps a workpiece, it often uses the method of stamping the workpiece into the mold. The mold consists of multiple mold cores and a mold base. After the multiple mold cores are closed, a cavity for the workpiece to be formed is formed. At the same time, the mold cores slide in the mold base through a power source to facilitate mold opening and closing. However, during the production process, the stamping force is sometimes too large, resulting in the mold cores being pushed towards the workpiece by the reaction force of the stamping force during the stamping of the workpiece, damaging the outer shape of the workpiece and reducing the yield rate. Summary of the Utility Model

[0004] In order to reduce the situation where the mold cores are extruded outwards when the workpiece is pressed into the mold cores, the present application provides a stamping structure of a horizontal stamping and forming device.

[0005] The stamping structure of a horizontal stamping and forming device provided by the present application adopts the following technical solutions:

[0006] A stamping mechanism of a horizontal stamping and forming device includes a workbench, a stamping driving device, a stamping device, a mold core assembly, and a mold core driving device. The stamping device and the mold core assembly are oppositely arranged on the workbench. The stamping device includes a base and a stamping rod. The base is slidably arranged on the workbench, and the stamping rod is installed on the base and arranged towards the mold core assembly. The mold core assembly includes several mold cores and a mold base. The mold base is installed on the workbench, and several of the mold cores are movably arranged in the mold base and are used to form a cavity for forming the workpiece after mold closing. The mold core driving device is used to drive the mold core assembly to open and close the mold. The stamping driving device is used to drive the base to drive the stamping rod to push the workpiece into the cavity. It also includes several tightening members. The tightening members are arranged on the base and are arranged one-to-one towards several of the mold cores. The tightening members are used to abut against the end faces of the corresponding mold cores when the stamping rod punches the workpiece into the mold core assembly.

[0007] Through the above technical solutions, when the stamping rod punches the workpiece into the mold core assembly, the tightening members on the base will tightly hold the corresponding mold cores in the mold base, preventing them from moving towards the workpiece under the reaction force of the stamping force, thereby enhancing the structural stability.

[0008] Preferably, the tightening member adopts an oil cylinder, and the telescopic rod of the oil cylinder remains in the extended state.

[0009] Through the above technical solution, using the oil cylinder as the abutting member has multiple advantages. First, the oil cylinder can provide a large pressure to abut against the die core to cope with the impact force. Second, the oil cylinder can work for a long time in a high-temperature environment without deteriorating like a spring, resulting in a decrease in the pressure on the die core, thereby increasing the service life of the workpiece. And the telescopic rod that remains extended can ensure that the oil cylinder abuts against the corresponding die core in the first time.

[0010] Preferably, an installation groove is provided on the end surface of the base, and one end of the oil cylinder is fixed in the installation groove.

[0011] Through the above technical solution, the cooperation between the installation groove and the oil cylinder increases the stability of the oil cylinder during operation.

[0012] Preferably, two die cores are provided. Guide grooves are formed on the inner wall of the die base, and the guide grooves are inclined towards the central axis of the die base; the die cores are slidably arranged in the guide grooves; the die core driving device realizes the opening and closing of the die core assembly by driving the two die cores to slide back and forth along the guide grooves.

[0013] Through the above technical solution, the guide grooves inclined towards the central axis of the die base drive the two die cores to move away from or close to each other during the opening and closing of the die, thereby achieving the purpose of opening and closing the die.

[0014] Preferably, a plurality of guide rods are further included. One end of each of the plurality of guide rods passes through the base, and the other end passes through the die base. The guide rods are arranged parallel to the moving direction of the base.

[0015] Through the above technical solution, the arrangement of the guide rods restricts the movement of the base perpendicular to the guide rods, thereby enhancing the stability of the base during stamping operations.

[0016] The technical effects of the present utility model are mainly reflected in the following aspects:

[0017] 1. By providing an abutting member, the present utility model prevents the die core from moving towards the workpiece under the reaction force of the punching force, thereby enhancing the structural stability;

[0018] 2. The present utility model uses an oil cylinder as the abutting member because the oil cylinder can work for a long time in a high-temperature environment without deteriorating like a spring, resulting in a decrease in the pressure on the die core, thereby increasing the service life of the workpiece;

[0019] 3. By providing guide rods, the present utility model restricts the movement of the base perpendicular to the guide rods, thereby enhancing the stability of the base during stamping operations. BRIEF DESCRIPTION OF THE DRAWINGS

Detailed description of the specific implementation mode

[0027] The following will further elaborate on the specific implementation mode of the present utility model in conjunction with the attached Figures 1-6 , so as to make the technical solution of the present utility model easier to understand and master.

[0028] The embodiment of the present application discloses a stamping and forming structure of a horizontal stamping and forming device:

[0029] Refer to Figures 1-6, a stamping mechanism of a horizontal stamping and forming device, comprising a workbench 1, a stamping drive device 10, a stamping device 2, a die core assembly 6 and a die core drive device 3. The stamping device 2 and the die core assembly 6 are oppositely arranged on the workbench 1. The stamping device 2 includes a base 21 and a stamping rod 22. The base 21 is slidably arranged on the workbench 1, and the stamping rod 22 is installed on the base 21 and is arranged towards the die core assembly 6. The die core assembly 6 includes a plurality of die cores and a die seat 7. The die seat 7 is installed on the workbench 1, and a plurality of die cores are movably arranged in the die seat 7. The plurality of die cores are used to form a cavity 63 for forming a workpiece after mold closing. The die core drive device 3 is used to drive the die core assembly 6 to open and close the mold. The stamping drive device 10 is used to drive the base 21 to drive the stamping rod 22 to push the workpiece into the cavity 63. The stamping drive device 10 can be driven by the cooperation of a servo motor and a pneumatic clutch, which belongs to the existing mature technology and will not be elaborated too much. There are also a plurality of pressing members 8. The pressing members 8 are arranged on the base 21 and are arranged one-to-one towards the plurality of die cores. The pressing members 8 are used to abut against the end faces of the corresponding die cores when the stamping rod 22 punches the workpiece into the die core assembly 6. When the stamping rod 22 punches the workpiece into the die core assembly 6, the pressing members 8 on the base 21 will press the corresponding die cores tightly in the die seat 7, preventing them from moving towards the workpiece under the reaction force of the punching force, thereby enhancing the structural stability.

[0030] Refer to Figure 3 , the pressing member 8 adopts an oil cylinder 81, and the telescopic rod of the oil cylinder 81 remains in the extended state. Using the oil cylinder 81 as the pressing member 8 has several advantages. Firstly, the oil cylinder 81 can provide a large pressure to abut against the die core to cope with the impact force. Secondly, the oil cylinder 81 can work for a long time in a high-temperature environment without deteriorating like the spring 41, resulting in a decrease in the pressure on the die core, thereby increasing the service life of the workpiece. The extended telescopic rod can ensure that the oil cylinder 81 abuts against the corresponding die core in the first place. At the same time, the overall length of the oil cylinder 81 after the telescopic rod extends should be greater than or equal to the length of the workpiece processed by the stamping rod 22. So that during the stamping process, the telescopic rod of the oil cylinder 81 can abut against the die core first, thereby preventing the workpiece from contacting the die core first and causing the die core to move towards the workpiece under the reaction force. An installation groove 211 is opened on the end face of the base 21, and one end of the oil cylinder 81 is fixed in the installation groove 211. The cooperation between the installation groove 211 and the oil cylinder 81 increases the stability of the oil cylinder 81 during operation.

[0031] Refer to Figures 4-5, the mold cores are set to two and are distinguished as a left mold core 61 and a right mold core 62. A guide groove 71 is formed on the inner wall of the mold base 7, and the guide groove 71 is inclined towards the central axis of the mold base 7; the left mold core 61 and the right mold core 62 are slidably arranged in the guide groove 71; the mold core driving device 3 realizes the opening and closing of the mold core assembly 6 by driving the left mold core 61 and the right mold core 62 to slide back and forth along the guide groove 71. The guide groove 71 inclined towards the central axis of the mold base 7 drives the left mold core 61 and the right mold core 62 to move away from or close to each other during the opening and closing of the mold, so as to achieve the purpose of opening and closing the mold.

[0032] Refer to Figure 3 , it further includes a plurality of guide rods 34. One end of each of the plurality of guide rods 34 is fixed on the base 21, and the other end passes through the mold base 7. The guide rods 34 are arranged parallel to the moving direction of the base 21. The guide rods 34 limit the movement of the base 21 perpendicular to the guide rods 34, thereby enhancing the stability of the base 21 during the stamping operation.

[0033] Refer to Figure 1 , it further includes a feeding structure 9. A working area 12 is arranged on the workbench 1, and the working area 12 is located between the stamping rod 22 and the mold core assembly 6. The feeding structure 9 is used to send the workpiece into the working area 12, and then the stamping rod 22 punches the workpiece into the mold core assembly 6.

[0034] Refer to Figures 5-6 , the driving assembly includes a driving rod 31, a moving block 32, a base block 33, a clamping assembly 4, and a pulling-back assembly 5. Two movable rods 311 are formed at the front end 233 of the driving rod 31, and the two movable rods 311 slide on the left mold 61 and the right mold 62 respectively along the sliding direction horizontally perpendicular to the driving seat 21.

[0035] Refer to Figure 2 and Figure 5 , a fixing frame 23 is arranged on the mold base 7. The moving block 32 slides on the fixing frame 23 along the moving direction parallel to the base 21, and the driving rod 31 passes through and is fixedly arranged on the moving block 32.

[0036] Refer to Figure 5 and Figure 6 , the length direction of the base block 33 is horizontally perpendicular to the moving direction of the base 21. One ends of the two guide rods 34 passing through the mold base are respectively fixedly arranged at both ends in the length direction of the base block 33. The clamping assembly 4 is arranged on the base block 33 and is used to clamp the driving rod 31 to drive the driving rod 31 to move synchronously towards the stamping device 2 side and to disengage from the driving rod 31 after the mold core assembly 6 is in the open mold state; the pulling-back assembly 5 is arranged on the fixing frame 23, and the pulling-back assembly 5 is used to drive the driving rod 31 to move towards the side away from the stamping device 2, driving the mold core assembly 6 to reset to the closed mold state.

[0037] Refer to Figures 4-6, when the left mold core 61 and the right mold core 62 are separated, the base 21 on the stamping device 2 retreats away from the mold base 7, drives the base block 33 and the clamping assembly 4 on the base block 33 through the guide rod 34. The clamping assembly 4 clamps the driving rod 31, and drives the driving rod 31 to move synchronously towards the stamping device 2 through the friction generated by the clamping, so as to drive the left mold core 61 and the right mold core 62 to separate in time until they are completely separated. At this time, the base 21 continues to retreat, and the clamping assembly 4 disengages from the driving rod 31; in this way, the separation of the left mold core 61 and the right mold core 62 can be more timely.

[0038] Refer to Figures 4-6 , when a new round of stamping is carried out after loading, the pulling-back assembly 5 drives the driving rod 31 to reset, and the left mold core 61 and the right mold core 62 are closed. At this time, the clamping assembly 4 is always disengaged from the driving rod 31, and then the base 21 moves towards the mold base 7 for stamping. At this time, the clamping assembly 4 clamps the driving rod 31 again.

[0039] Refer to Figures 5-6 , the clamping assembly 4 includes two sliding rods 42, two first blocks 43, two springs 41 and two clamping blocks 44. The fixing frame 23 includes two fixing rods 231. The base block 33 is provided with an avoidance through groove 331 for the two fixing rods 231 to pass through.

[0040] Refer to Figures 5-6 , the two fixing rods 231 are respectively located on both sides of the driving rod 31. The side surfaces of the two fixing rods 231 away from each other have an inclined step surface 232, and the distance between the two step surfaces 232 gradually becomes smaller towards the side away from the mold base 7; the two first blocks 43 are arranged oppositely on the base block 33, and the two first blocks 43 are respectively located above and below the fixing rod 231. The two sliding rods 42 are slidably connected to the first block 43 along the direction perpendicular to the movement direction of the base block 33. The two clamping blocks 44 are respectively fixedly arranged on the two sliding rods 42, and the two clamping blocks 44 are respectively located on the left and right sides of the driving rod 31. The two sliding rods 42 are respectively located on both sides of the two fixing rods 231. The first block 43 is provided with a waist-shaped hole 431 for the sliding rod 42 to slide. The two ends of the sliding rod 42 respectively extend to the upper and lower sides of the two first blocks 43. The two springs 41 are respectively located above and below the two first blocks 43. The two ends of the spring 41 are respectively fixedly arranged on the corresponding ends of the two sliding rods 42. The spring 41 pulls the two sliding rods 42 to approach each other, so that the sliding rod 42 can always abut against the side wall of the fixing rod 231.

[0041] Refer to Figures 4-6, during the mold opening process of the left mold core 61 and the right mold core 62, the base 21 retreats away from the mold base 7 side, drives the base block 33 to move through the guide rod 34, the base block 33 drives the first block 43 and the slide rod 42 to move. The part of the fixing rod 231 located on the step surface 232 close to the base 21 is the front end 233 of the fixing rod 231, and the part of the fixing rod 231 located on the step surface 232 close to the base 21 is the rear end 234 of the fixing rod 231. The slide rod 42 initially abuts against the side wall of the rear end 234 of the fixing rod 231. At this time, the two clamping blocks 44 clamp the driving rod 31 and can drive the driving rod 31 to move synchronously. When it moves to the state where the left mold core 61 and the right mold core 62 are completely opened, at this time, since the driving rod 31 can no longer move forward, so a slide occurs between the two clamping blocks 44 and the driving rod 31 until the slide rod 42 moves to abut against the step surface 232 and the side wall of the front end 233 of the fixing rod 231, then the two slide rods 42 move away from each other, and at this time the two clamping blocks 44 completely disengage from the fixing rod 231.

[0042] Referring to Figure 4 and Figure 6 , the pulling-back assembly 5 is a one-way oil cylinder 51. The one-way oil cylinder 51 is located on the side of the mold base 7 away from the stamping device 2. The cylinder body of the one-way oil cylinder 51 is fixedly connected to the fixing frame 23, and the piston rod of the one-way oil cylinder 51 extends towards the mold base 7 side and is fixed to the driving rod 31.

[0043] Of course, the above are only typical examples of the present invention. In addition, the present invention can also have many other specific implementation manners. Any technical solutions formed by equivalent replacement or equivalent transformation fall within the scope of protection required by the present invention.
