See patent publication No. CN106523216B for details.

Wherein, punch assembly includes drift 211 and electric putter 212.

The punch 211 is slidably connected to the machine body 100, and can perform a reciprocating linear motion between a first working position a and a second working position a along a longitudinal direction, and comprises a first section and a second section which are connected with each other, wherein the first section is conical, one end far away from the second section is a smaller end, the second section is cylindrical, and the radius of the second section is adapted to the maximum radius of the first section.

The electric push rod 212 is fixedly connected with the machine body 100, is fixedly connected with one end, far away from the first section, of the second section of the punch 211, and is used for driving the punch 211 to perform reciprocating linear motion between a first working position A and a second working position A. Specifically, the power output shaft of the electric push rod 212 is fixedly connected with the tool rest 213, and the punch 211 is fixedly connected with one end of the tool rest 213 away from the electric push rod 212.

When the electric pushing rod 212 is used, the electric pushing rod 212 extends, so that the punch 211 is driven to move upwards from the first working position A to the second working position A, the purpose of punching the bottom of the scraped car fuel tank is achieved, and accordingly fuel and oil gas in the fuel tank can flow out through holes punched by the punching assembly to be recovered by the fuel receiving assembly and the fuel steam recovery assembly respectively.

However, the above-mentioned punching assembly has the disadvantages that: because the fuel tank is made of metal, punching the fuel tank through the punch 211 can lead the side wall of the fuel tank to be rolled inwards, thereby forming a containing cavity with the inner wall of the fuel tank, and further leading the fuel in the fuel tank to not flow out of the holes punched by the punching assembly completely. Thus, in one embodiment, the punch assembly further includes a cutting edge 214 and a drive assembly.

The number of the cutting edges 214 is plural, the plural cutting edges 214 are disposed on the second section and/or the first section of the punch 211 and are uniformly distributed around the axial line of the punch 211, preferably, the cutting edges 214 are disposed on the second section of the punch 211, the first end of the cutting edge 214 is hinged with the punch 211, and the second end can swing reciprocally between a first working position B and a second working position B around the hinged central line of the second end, wherein when the cutting edge 214 is in the first working position B, the cutting edge 214 is retracted into the side wall of the punch 211, thereby facilitating punching of the punch 211; when the cutting edge 214 is in the second working position B, the cutting edge 214 extends beyond the side wall of the punch 211, and the second end of the cutting edge 214 is located a greater distance from the axis of the punch 211 than the radius of the second section of the punch 211.

A drive assembly is mounted on the punch 211 and/or the cutting edge 214 for driving the cutting edge 214 in reciprocating rotation between a first operative position B and a second operative position B.

When the fuel tank punching device is used, firstly, the electric push rod 212 drives the punch 211 to move upwards from the first working position A to the second working position A, so that the punch 211 breaks the side wall of the fuel tank and moves into the fuel tank, when the punch 211 moves into the fuel tank, the driving component drives the cutting blade 214 to move from the first working position B to the second working position B, then the electric push rod 212 contracts, so that the punch 211 moves downwards from the second working position A to the first working position A, and under the action of the cutting blade 214, the inner wall of the fuel tank which is curled inwards is pulled outwards, the inner wall of the fuel tank is broken, and the purpose that fuel in the fuel tank can flow out of a hole punched by the punching component completely is achieved.

Specifically, in one embodiment, the drive assembly includes a sliding sleeve 215, a push rod 216, and a drive mechanism.

The sliding sleeve 215 is coaxially disposed with the punch 211, and specifically, the sliding sleeve 215 is sleeved on the tool rest 213, and can perform reciprocating linear motion between the first working position C and the second working position C along the axial line direction of the sliding sleeve 215. The number of push rods 216 is equal to and corresponds to the number of cutting edges 214, and the first ends of the push rods 216 are hinged with the sliding sleeve 215, and the second ends are hinged with the cutting edges 214. The driving mechanism is used for driving the sliding sleeve 215 to do reciprocating linear motion between the first working position C and the second working position C.

When the sliding sleeve 215 is driven upwards from the first working position C to the second working position C under the action of the driving mechanism, the push rod 216 drives the cutting blade 214 to rotate from the first working position B to the second working position B under the action of the push rod 216, so that the aim of expanding the cutting blade 214 is fulfilled.

The driving component with the structure has simple structure and reasonable design.

In one embodiment, the drive mechanism includes a permanent magnet 217, an electromagnet 218, and a torsion spring (not shown in the figures).

The permanent magnet 217 is fixedly inlaid at one end of the sliding sleeve 215 far away from the punch 211, namely the bottom end of the sliding sleeve 215. The electromagnet 218 is positioned at one end of the permanent magnet 217 away from the punch 211, i.e. the electromagnet 218 is positioned below the permanent magnet 217, and the electromagnet 218 is fixedly connected with the power output shaft of the electric push rod 212. Specifically, the electromagnet 218 is fixedly connected to the tool post 213.

The number of torsion springs is equal to and one-to-one corresponding to the number of the cutting edges 214, and the torsion springs are installed at the hinge center line of the cutting edges 214.

Wherein when the magnetism of the side of the electromagnet 218 opposite to the permanent magnet 217 is the same, the torsion spring has a tendency to move the cutting edge 214 from the second working position C to the first working position C in a natural state; when the magnetism of the electromagnet 218 on the opposite side from the permanent magnet 217 is reversed, the torsion spring has a tendency to move the cutting edge 214 from the first working position C to the second working position C in a natural state.

In use, assuming that the electromagnet 218 is of the same magnetic nature as the opposite side of the permanent magnet 217, initially the electromagnet 218 is de-energized, under the influence of the torsion spring, to hold the cutting edge 214 in the first operative position C.

After the punch 211 moves upward from the first working position a to the second working position B under the action of the electric push rod 212 and finally enters the fuel tank, the electromagnet 218 is electrified, and the sleeve moves upward from the first working position B to the second working position B under the action of magnetic repulsion force of the electromagnet 218 and the permanent magnet 217, so that the cutting edge 214 is pushed by the push rod 216 to move from the first working position C to the second working position C against the elastic force of the torsion spring. Then, the electric push rod 212 is contracted, so that the punch 211 is driven to descend from the second working position A to the first working position A, and the cutting edge 214 extends out of the side wall of the punch 211, so that the side wall of the fuel tank is pulled downwards under the action of the cutting edge 214 in the retracting process of the punch 211, and the purpose that fuel in the fuel tank can completely flow out of a hole formed by the punching assembly is achieved.

Similarly, when the magnetism of the opposite side of the electromagnet 218 from the permanent magnet 217 is opposite, initially, the electromagnet 218 is energized, and the sleeve is held in the first working position B by the magnetic attraction of the electromagnet 218 and the permanent magnet 217, thereby holding the cutting edge 214 in the first working position C by the push rod 216;

after the punch 211 moves upward from the first working position a to the second working position B and finally into the fuel tank under the action of the electric push rod 212, the electromagnet 218 is de-energized, and the cutting blade 214 rotates from the first working position C to the second working position C under the action of the spring force of the torsion spring, so that the sleeve moves upward from the first working position B to the second working position B by the push rod 216. Then, the electric push rod 212 contracts, so that the punch 211 is driven to descend from the second working position A to the first working position A, and the cutting edge 214 extends out of the side wall of the punch 211, so that the side wall of the fuel tank is pulled downwards under the action of the cutting edge 214 in the retracting process of the punch 211, and the purpose that fuel in the fuel tank can completely flow out of a hole formed by the punching assembly is achieved.

Preferably, in this embodiment, the electromagnet 218 is magnetically identical to the opposite side of the permanent magnet 217, such that the cutting edge is maintained in the first operative position C by the spring force of the torsion spring when the electromagnet 217 is not energized.

The driving mechanism with the structure has simple structure and reasonable design.

In one embodiment, a cleaning assembly is further included for cleaning the cutting edge 214 and/or a receiving slot formed in the punch 211 for receiving the cutting edge 214, the cleaning assembly including an air outlet 310 and an air pump 320.

The air outlet 310 is formed on the side of the accommodating groove facing the axial lead of the punch 211. The air pump 320 is fixedly installed on the machine body 100, and an air outlet thereof is communicated with the air outlet hole 310. Specifically, the tool rest 213 is provided with a first air passage, the punch 211 is provided with a second air passage, the first air passage is communicated with the second air passage, the second air passage is communicated with the air outlet, the air pump 320 is communicated with the first air passage through a cleaning pipe 330, and the cleaning pipe is provided with a third control valve 340.

During the use, the air pump 320 is inflated to the venthole 310 to reach the purpose of cleaning up the impurity in the holding tank, and then reach the purpose that avoids impurity to influence cutting edge 214 and retract, simultaneously, the gaseous that flows out from venthole 310 gets into the fuel tank through the hole that the subassembly of punching was got into, thereby reaches the purpose that accelerates the fuel volatilization on the adhesion fuel tank inner wall, and then reaches the purpose that improves the recovery effect.
