Detailed Description
The following are specific embodiments of the present invention and are further described with reference to the drawings, but the present invention is not limited to these embodiments.
Referring to fig. 1 to 4, the present invention discloses a support structure of a long cantilever, including:
a fixing assembly 200 for mounting one end of the long cantilever 100, which includes a fixing base 210, wherein the long cantilever 100 moves relative to the fixing base 210 along a first direction to connect or disconnect the long cantilever 100 with or from the fixing base 210;
the sliding assembly 300 is used for mounting the other end of the long cantilever 100 and comprises a sliding seat 310, wherein the sliding seat 310 moves relative to the fixed seat 210 along a second direction to connect or disconnect the long cantilever 100 with or from the sliding seat 310.
Further, the second direction is perpendicular to the first direction.
In this embodiment, set up fixed subassembly 200 and sliding component 300, fix the both ends of long cantilever 100 respectively, avoid long cantilever 100 to produce deformation when the atress and lead to the mould life-span to shorten, also solved the problem that the finished product quality is poor because of long cantilever 100 mold core deformation leads to simultaneously.
Specifically, the long cantilever 100 is moved in a first direction to connect one end thereof with the fixed seat 210, and then the product (the workpiece 400 to be punched) is mounted on the long cantilever 100, and finally the sliding seat 310 is moved in a second direction to support the other end of the long cantilever 100, so that the mounting of the long cantilever 100 is completed, and the next step of punching can be performed.
It should be noted that in this embodiment, the first direction is perpendicular to the second direction, so that the sliding seat 310 slides along the second direction, and further disengages from the long cantilever 100, and leaves the space of the long cantilever 100 in the first direction, so that one end of the long cantilever 100 is free, and when a workpiece is installed, the workpiece can enter from the free end of the long cantilever 100 and is sleeved on the long cantilever 100; therefore, the problem of stress deformation caused by one end of the long cantilever 100 being free during processing due to the fact that the mold core of the long cantilever 100 needs to be arranged inside the workpiece in a penetrating mode is solved.
Further, the fixing base 210 is provided with a fixing hole 211, and a limiting block 212 is slidably disposed on the fixing base 210, and the limiting block 212 moves along a third direction relative to the fixing base 210 to slide into or withdraw from the fixing hole 211; the third direction is perpendicular to the first direction;
the long cantilever 100 is provided with a limiting groove 110, and the limiting block 212 slides into the limiting groove 110 to lock the long cantilever 100 to move along the first direction relative to the fixing seat 210.
The long cantilever 100 is fixedly connected with the fixed seat 210 by arranging the limiting block 212 and the limiting groove 110; the third direction is perpendicular to the first direction, so that the sliding of the limiting block 212 and the sliding of the long cantilever 100 do not interfere with each other, and the locking effect of the limiting block 212 is further improved.
Further, a first self-locking inclined surface 120 is arranged on the long cantilever 100;
a second self-locking inclined surface 311 is arranged on the sliding seat 310;
the long cantilever 100 moves in a first direction relative to the fixed base 210 and/or the sliding base 310 moves in a second direction relative to the long cantilever 100 to make the first self-locking inclined surface 120 abut against the second self-locking inclined surface 311.
The first self-locking inclined surface 120 and the second self-locking inclined surface 311 are attached to each other, so that the end part of the long cantilever 100 is supported by the sliding seat 310, and the long cantilever 100 is prevented from deforming under stress.
Further, the heights of the first and second self-locking slopes 120 and 311 are gradually decreased toward the sliding assembly 300 by the fixing assembly 200.
Further, the included angle between the first self-locking inclined surface 120 and the first direction and the included angle between the second self-locking inclined surface 311 and the first direction are 3 degrees to 5 degrees.
The first self-locking inclined surface 120 and the second self-locking inclined surface 311 are arranged to incline, so that the first self-locking inclined surface 120 and the second self-locking inclined surface 311 can form a self-locking angle, and no matter how much force is applied during punching, the first self-locking inclined surface 120 and the second self-locking inclined surface 311 cannot slide relatively (namely, the friction force is greater than the downward sliding force).
More importantly, the first self-locking inclined surface 120 and the second self-locking inclined surface 311 are arranged to incline, so that the height error of the supporting seat can be absorbed, and the processing quality of a product is improved.
Specifically, if the first self-locking inclined surface 120 and the second self-locking inclined surface 311 are horizontal planes (i.e., parallel to the first direction), the height requirement of the supporting seat is very high; if the height of the supporting seat is low, the two self-locking inclined planes cannot be attached to each other, the supporting effect cannot be achieved, and the long cantilever 100 is stressed and easily deformed, so that the quality of a finished product is influenced; if the height of the supporting seat is high, the two ends of the long cantilever 100 are not uniform in height and are bent and deformed, which may affect the processing quality of the workpiece, and even cause the supporting seat to be unable to slide below the long cantilever 100, so that the first self-locking inclined surface 120 and the second self-locking inclined surface 311 are unable to be attached.
Therefore, in this embodiment, the first self-locking inclined surface 120 and the second self-locking inclined surface 311 are arranged to form an included angle of 3 ° to 5 ° with the first direction, so long as the height of the support seat is within an allowable range, the first self-locking inclined surface 120 can be attached to the second self-locking inclined surface 311 by moving the long cantilever 100 along the first direction, and thus the problem caused by too high or too low height of the support seat is avoided, and the processing quality of the workpiece is improved.
Furthermore, two self-locking inclined planes are arranged to incline, so that the process of sliding the supporting seat into and out of the lower part of the long cantilever 100 is smoother. Specifically, if two self-locking inclined planes are arranged to be horizontal, when the supporting seat slides in and out of the position below the long cantilever 100, sliding friction exists between the supporting seat and the long cantilever 100 all the time, and the process is unsmooth and laborious; the two self-locking surfaces are arranged to incline, the long cantilever 100 can slide a short distance from the initial position along the first direction before the withdrawing or sliding-in action, the two self-locking inclined surfaces are prevented from contacting, then the supporting seat slides into or withdraws from the lower part of the long cantilever 100, and finally the long cantilever 100 returns to the initial position, so that the two self-locking inclined surfaces are attached. In the whole process, sliding friction does not exist between the two self-locking inclined planes, so that the processes of withdrawing and sliding the supporting seat are smoother.
Meanwhile, the first self-locking inclined surface 120 and the second self-locking inclined surface 311 are arranged, so that the contact area of the two inclined surfaces can be increased, and the stress of unit area is reduced.
Further, a first limiting portion 130 is further disposed on the long cantilever 100, and the first limiting portion 130 is connected to the first self-locking inclined surface 120;
the sliding seat 310 is provided with a second limiting portion 312, and the second limiting portion 312 is connected with the second self-locking inclined surface 311;
the long cantilever 100 moves in a first direction relative to the sliding seat 310 to make the first position-limiting portion 130 abut against or separate from the second position-limiting portion 312.
Preferably, the heights of the first and second self-locking slopes 120 and 311 are gradually increased or decreased along the second direction, so that the support seat has a guiding function when exiting or entering below the long cantilever 100.
The first position-limiting portion 130 and the second position-limiting portion 312 are disposed to prevent the long cantilever 100 from moving excessively and falling off the fixing base 210.
Further, the sliding assembly 300 further includes: a guide rail 320 disposed along the second direction, the sliding seat 310 being slidable along the guide rail 320; and a driving cylinder 330 connected to the sliding seat 310 for driving the sliding seat 310 to slide along the guide rail 320.
Further, referring to fig. 5-6, the utility model also discloses a punching die with a closed cross section, which comprises the support structure of the long cantilever, wherein the long cantilever 100 is arranged in the workpiece 400 to be punched in a penetrating way.
Further, the method also comprises the following steps: a plurality of first lateral support members 500 and a plurality of second lateral support members 600, the first lateral support members 500 and the second lateral support members 600 being respectively disposed at opposite sides of the workpiece 400 to be punched;

the second lateral supporting assembly 600 comprises a second supporting block 610 and a second fixing block 620, wherein a waist-shaped groove 611 is formed in the second supporting block 610, and the second supporting block 610 is connected with the second fixing block 620 through a bolt via the waist-shaped groove.
Specifically, in the first lateral support assembly 500, the first support block 510 supports the lateral side of the workpiece to be punched 400 by means of the telescopic support cylinder 520; in the second lateral supporting assembly 600, the second fixing block 620 is bolted by adjusting different positions of the waist-shaped groove 611, so that the second supporting block 610 supports the lateral side of the workpiece 400 to be punched.
