These are prior art and will not be described in any greater detail herein. For details, see patent with grant publication number CN 106523216B.

Wherein, the punching assembly comprises a punch 211 and an electric push rod 212.

The punch 211 is slidably connected to the body 100, and can move in a reciprocating linear motion between a first working position a and a second working position a along a longitudinal direction, and includes a first section and a second section which are connected to each other, wherein the first section is conical and has a smaller end at an end far away from the second section, the second section is cylindrical, and a radius of the second section is adapted to a 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 of the second section of the punch 211, which is far away from the first section, 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, a power output shaft of the electric push rod 212 is fixedly connected with the tool holder 213, and the punch 211 is fixedly connected with one end of the tool holder 213 far away from the electric push rod 212.

When the punching device is used, the electric push 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 fuel oil and oil gas in the fuel tank can flow out through holes punched by the punching assembly to be respectively recovered by the fuel receiving assembly and the fuel steam recovery assembly.

However, the punching assembly has the following disadvantages: because the fuel tank is made of metal, the side wall of the fuel tank is curled inwards by punching the fuel tank through the punch 211, so that a containing cavity is formed between the side wall of the fuel tank and the inner wall of the fuel tank, and further, the fuel in the fuel tank cannot completely flow out of a hole punched by the punching component. Accordingly, in one embodiment, the punch assembly further includes a cutting edge 214 and a drive assembly.

The number of the cutting edges 214 is multiple, the multiple cutting edges 214 are arranged on the second section and/or the first section of the punch 211 and are uniformly distributed around the axial lead of the punch 211, preferably, the cutting edges 214 are arranged on the second section of the punch 211, the first end of each cutting edge 214 is hinged with the punch 211, and the second end of each cutting edge 214 can swing back and forth between a first working position B and a second working position B around the hinge central line of the cutting edge 214, wherein when the cutting edges 214 are located at the first working position B, the cutting edges 214 retract into the side wall of the punch 211, so that punching of the punch 211 is facilitated; when the cutting edge 214 is in the second working position B, the cutting edge 214 extends beyond the sidewall of the punch 211, and the second end of the cutting edge 214 is located at a greater distance from the axial center line 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 working position B and a second working position B.

When the punch 211 moves into the fuel tank, the driving assembly drives the cutting edge 214 to move from the first working position B to the second working position B, and 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, under the action of the cutting edge 214, the inwardly curled inner wall of the fuel tank is pulled outwards and the inner wall of the fuel tank is broken, and further the purpose that fuel in the fuel tank can completely flow out of a hole punched by the punching assembly 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 holder 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 the push rods 216 is equal to and corresponds to the number of the cutting blades 214, and the first end of the push rods 216 is hinged to the sliding sleeve 215, and the second end is hinged to the cutting blades 214. The driving mechanism is used for driving the sliding sleeve 215 to move back and forth in a straight line between the first working position C and the second working position C.

When the cutting device is used, under the action of the driving mechanism, 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 push rod 216, the push rod 216 drives the cutting edge 214 to rotate from the first working position B to the second working position B, and then the purpose of unfolding the cutting edge 214 is achieved.

The driving assembly with the structure has a 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 embedded 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 far away from the punch 211, namely 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, electromagnet 218 is fixedly coupled to tool holder 213.

The number of torsion springs is equal to and corresponds one-to-one with the number of cutting edges 214, the torsion springs being mounted at the hinge centerline of the cutting edges 214.

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

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

After the punch 211 is moved upwards from the first working position a to the second working position B by the electric push rod 212 and finally enters the fuel tank, the electromagnet 218 is energized, and the sleeve is moved upwards from the first working position B to the second working position B by the magnetic repulsion force of the electromagnet 218 and the permanent magnet 217, so that the push rod 216 pushes the cutting edge 214 to move from the first working position C to the second working position C against the elastic force of the torsion spring. The electric push rod 212 is then retracted to drive the punch 211 to descend from the second working position a to the first working position a, and since the cutting edge 214 extends out of the side wall of the punch 211, the side wall of the fuel tank is pulled down by the cutting edge 214 during the retraction of the punch 211, so as to achieve the purpose that the fuel in the fuel tank can completely flow out of the hole of the punching assembly.

Similarly, when the electromagnet 218 is opposite in polarity to the side opposite to the permanent magnet 217, initially, the electromagnet 218 is energized, and the sleeve is held in the first working position B by the magnetic attraction between the electromagnet 218 and the permanent magnet 217, so that the cutting edge 214 is held in the first working position C by the push rod 216;

after the punch 211 is moved upward from the first working position a to the second working position B by the electric push rod 212 and finally enters the fuel tank, the electromagnet 218 is de-energized, and the cutting edge 214 is rotated from the first working position C to the second working position C by the elastic force of the torsion spring, so that the sleeve is moved upward from the first working position B to the second working position B by the push rod 216. The electric push rod 212 is then retracted to drive the punch 211 to descend from the second working position a to the first working position a, and since the cutting edge 214 has extended out of the side wall of the punch 211, the side wall of the fuel tank is pulled down by the cutting edge 214 during the retraction of the punch 211, so as to achieve the purpose of enabling the fuel in the fuel tank to completely flow out of the hole of the punching assembly.

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

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

In one embodiment, the device further comprises a cleaning assembly for cleaning the cutting edge 214 and/or a receiving groove formed on the punch 211 and used for receiving the cutting edge 214, wherein the cleaning assembly comprises an air outlet 310 and an air pump 320.

The gas outlet hole 310 is opened on the side of the housing groove facing the axial line 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, a first air passage is formed in the tool rest 213, a second air passage is formed in the punch 211, 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 the cleaning pipe 330, and the third control valve 340 is installed on the cleaning pipe.

During the use, the air pump 320 is aerifyd in to the venthole 310 to reach the purpose that carries out the impurity in the holding tank and clear up, and then reach the purpose of avoiding impurity influence cutting edge 214 to retract, simultaneously, the gas that flows out from the venthole 310 gets into in the fuel tank through the hole that the subassembly of punching was beaten, thereby reaches the mesh that accelerates the fuel on the adhesion fuel tank inner wall volatile, and then reaches the purpose that improves the recovery effect.
