Description

Technical Field

[0001] The invention relates to the technical field of punching dies, in particular to a double-cavity multi-directional punching integrated internal high-pressure hydraulic forming die. Background Art

[0002] A punching die is a die used to punch holes of a specific shape on materials such as metal, plastic, and leather. It mainly includes an upper die plate, a lower die, and a discharge device. When the slide of the punch press drives the upper die part downward, the punch first contacts the material, and then under the action of pressure, the punch gradually cuts into the material, causing the material to shear and deform under the action of the punch and die. Under the action of shear force, the internal stress of the material exceeds its shear strength limit, and the material will be separated to form the required hole.

[0003] A Chinese invention patent with publication number CN109530535B discloses a mold and method for pre-punching hot-formed products, including: a mold base and a punch, wherein a concave mold and a release groove are provided in the mold base, and auxiliary heads are provided on both sides of the punch, and the shapes of the release groove and the auxiliary head are both semi-elliptical; during pre-punching, the punch punches toward the concave mold so that the punch is inserted into the groove, and the auxiliary head is inserted into the release groove, so that the pre-hole and the release groove are punched out on the product. The present invention punches auxiliary holes on both sides of the pre-hole of the product during pre-punching to release the clamping force applied to the punching punch due to thermal expansion and contraction of the product during punching, so that the product can be stripped using a traditional stripping mechanism. The present invention also provides a process using the above-mentioned mold to punch out a release groove, so that the product pre-punched by the present invention can be stripped using a traditional stripping mechanism after punching.

[0004] In addition, since the punching speed required for punching metal tubes of different thicknesses is different, when the speed is too high, the heat generated by the friction between the drill bit and the metal will increase rapidly. Excessive heat will increase the plasticity of the metal material. During the drilling process, the metal is prone to deformation, especially at the exit of the hole, and the deformed metal will form burrs. On the contrary, when the cutting speed is too slow, the cutting force of the drill bit on the metal is uneven, which may also cause burrs. At the same time, the uncooled burrs have low hardness and are therefore easy to remove. In addition, when it is necessary to drill holes in different positions of the metal tube, manual rotation is required, which is not only cumbersome, but also affects the distance between the holes, and ultimately leads to the problem of reduced aesthetics of the metal tube or size mismatch. Therefore, the mold and method for pre-punching of hot-formed products disclosed in Chinese invention patent CN109530535B cannot clean burrs in time, nor can it perform multiple precise drillings on the metal tube. Summary of the invention

[0037] The following is the working process and principle of the above embodiment:

[0038] The initial state is as follows: the hydraulic telescopic rod 31 is in an uncontracted state, the spring 414 is in an uncompressed state, and the magnetic block plate 53 and the metal tube 2 are in a non-magnetically attracted state.

[0039] The working steps are as follows:

[0040] First, the operator inserts the bottom of the metal cylinder 2 into the installation groove 43, and makes the metal cylinder 2 sleeved on the outer wall of the lower mold table 41, and then the magnetic block plate 53 begins to magnetically attract the metal cylinder 2, so that the metal cylinder 2 moves toward the side close to the protective shell 51, so that the metal cylinder 2 resists the sliding rod 2 410 and slides toward the inside of the protective shell 51 inside the fixed plate 1 44, so that the sliding rod 2 410 drives the baffle plate 411 to slide toward the side close to the fixed plate 1 44 synchronously, so that the baffle plate 411 compresses the spring 414 toward the side close to the fixed plate 1 44, so that the baffle plate 411 drives the hinge block 412 fixedly connected thereto to move synchronously, so that the hinge block 412 drives the hinge rod 413 rotatably connected thereto to move toward the side close to the fixed plate 1 One side of 44 rotates, so that the hinge rod 413 drives the extrusion plate 47 to move toward the side close to the slide bar 2 410 through the hinge block 412 fixedly connected to the extrusion plate 47, so that the extrusion plate 47 drives the slide bar 1 46 to move inside the slide groove 45 toward the side close to the slide bar 2 410, and then the extrusion plate 47 drives the grinding plate 48 to move toward the side close to the metal cylinder 2, so that the grinding plate 48 clamps the outer wall of the metal cylinder 2, and the burrs are cleaned by clamping the metal cylinder 2 with the grinding plate 48, which avoids the burrs of the metal cylinder 2 from being cooled during the transfer process, and prevents the problem of the burrs being too hard to remove after cooling, which not only achieves the timeliness of burr cleaning, but also reduces the difficulty of removing burrs.

[0041] After the metal cylinder 2 is fixed on the outer wall of the lower mold platform 41, the operator controls the hydraulic telescopic rod 31 to start to reciprocate downward once through the driving motor 33, so that the telescopic end of the hydraulic telescopic rod 31 drives the upper mold platform 32 to move downward, so that the upper mold platform 32 drives the driving motor 33 to move downward synchronously, so that the driving motor 33 drives the punch 35 to move downward synchronously through the mounting plate 34, so that the punch 35 punches the metal cylinder 2 downward. When the punching of the top of the metal cylinder 2 is completed and the hydraulic telescopic rod 31 drives the punch 35 to move to the initial position, the driving motor 33 drives the punch 35 to move downward synchronously. The machine 33 starts to control the rotating rod 2 511 to rotate 360 ​​degrees, so that the rotating rod 2 511 drives the top of the fixed plate 3 512 to rotate synchronously. In the process that the rotating rod 2 511 drives the top of the fixed plate 3 512 to move from the bottom of the fixed plate 2 510 to the top of the fixed plate 2 510, the bottom end of the fixed plate 3 512 first drives the clamping plate 58 to flip to the side away from the ratchet plate 54 with the shaft 57 as the axis through the rotating block 59, and makes the clamping plate 58 resist the ratchet plate 54 to rotate a certain distance. After the locking plate 56 is in contact with the locking plate 58, the locking plate 58 continues to contact the ratchet plate 54 to rotate. At the same time, the rotating block 59 contacts the contact rod 56 to drive the transmission plate 55 to rotate, so that the transmission plate 55 starts to rotate upward with the rotating rod 1 52 as the axis, and then the transmission plate 55 drives the locking plate 58 to disengage from the ratchet plate 54 through the shaft 57. When the rotating rod 2 511 drives the top of the fixing plate 3 512 to move from the top of the fixing plate 2 510 to the bottom of the fixing plate 2 510, the transmission plate 55 enters the next tooth gap set by the ratchet plate 54 again through the shaft 57, and enters The ratchet plate 54 is caused to rotate intermittently, so that the ratchet plate 54 drives the rotating rod 52 to rotate synchronously, and the ratchet plate 54 drives the metal cylinder 2 to rotate synchronously on the outer wall of the lower mold table 41 through the magnetic block plate 53, thereby adjusting the position of the drilling hole of the metal cylinder 2. The ratchet plate 54 drives the metal cylinder 2 to rotate intermittently, thereby avoiding the operator's need to manually adjust the metal cylinder 2 and preventing the distance between adjacent drill holes from being uneven, which not only improves the production efficiency of the drilling of the metal cylinder 2, but also improves the aesthetics of the metal cylinder 2 and the adaptability of the drilling of the metal cylinder 2.
