[0005] The purpose of this utility model is achieved as follows:

[0006] An automatic casing removal device for a high-pressure cartridge case includes a casing receiving slide, a pry bar, and a pry bar cylinder. The casing receiving slide is U-shaped. The middle part of the pry bar is hinged between the two walls of the casing receiving slide. A slotting cylinder is fixed longitudinally on the upper surface of the pry bar. A V-shaped slot is fixed on the piston rod of the slotting cylinder. The slotting cylinder is used to drive the V-shaped slot to extend. The V-shaped slot is used to lock into the groove of the primer of the high-pressure cartridge case for positioning. The piston rod of the pry bar cylinder is poweredly connected to the driving end of the pry bar. The pry bar cylinder is used to drive the driving end of the pry bar to move. The actuating end of the pry bar is used to pry out the high-pressure cartridge case through the V-shaped slot.

[0007] Preferably, the cylinder body of the skid cylinder and the housing slide are in a relatively fixed relationship, and a connecting rod is hinged between the piston rod of the skid cylinder and the driving end of the skid.

[0008] Preferably, the receiving slide is inclined, and after the high-pressure cartridge case is pried out, it falls into the receiving slide, and the receiving slide outputs the high-pressure cartridge case by gravity.

[0009] Due to the adoption of the above technical solution, this utility model has the following beneficial effects:

[0010] This invention enables the extraction of cartridge cases, is compatible with automated firing of high-pressure bullets, and saves labor costs, reduces manual labor intensity, and significantly improves the safety of high-pressure firing. Attached Figure Description

[0013] Figure Labels

[0014] In the attached diagram, 45 is a V-shaped slot; 46 is a slot cylinder; 47 is a skid; 48 is a skid cylinder; 49 is a connecting rod; and 50 is a housing slide. Detailed Implementation

[0015] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0016] An automatic casing removal device for high-pressure cartridge cases includes a casing receiving slide 50, a pry bar 47, and a pry bar cylinder 48. The casing receiving slide 50 is U-shaped. The pry bar 47 is hinged at its center between the two walls of the casing receiving slide 50. A slotting cylinder 46 is longitudinally fixed to the upper surface of the pry bar 47. A V-shaped slot 45 is fixed on the piston rod of the slotting cylinder 46. The slotting cylinder 46 is used to drive the V-shaped slot 45 to extend, and the V-shaped slot 45 is used to lock into the groove of the primer of the high-pressure cartridge case for positioning. The piston rod of the pry bar cylinder 48 is poweredly connected to the driving end of the pry bar 47. Utilizing the lever principle, the pry bar cylinder 48 drives the driving end of the pry bar 47 to move, and the actuating end of the pry bar 47 pries out the high-pressure cartridge case through the V-shaped slot 45. The pry bar 47 has a U-shaped head, which supports both sides of the V-shaped slot 45 and makes room for the high-pressure cartridge case.

[0017] The cylinder body of the skid cylinder 48 and the housing slide 50 are relatively fixed and can be directly fixed by a connecting piece. A connecting rod 49 is hinged between the piston rod of the skid cylinder 48 and the drive end of the skid 47. In this embodiment, the cylinder body of the skid cylinder 48 is fixed on a fixing piece outside the housing slide 50, which is not shown.

[0018] Of course, the pry bar cylinder 48 can also be hinged at one end to the fixed part and at the other end to the drive end of the pry bar 47.

[0019] The receiving slide 50 is inclined. After the high-pressure cartridge case is pried out, it falls into the receiving slide 50, and the receiving slide 50 outputs the high-pressure cartridge case by gravity. In this embodiment, the receiving slide 50 includes two parts: one part is used to install the various components, and the other part narrows and outputs the high-pressure cartridge case.

[0020] The working process of this utility model:

[0021] The slot cylinder extends, and the V-shaped slot on the slot cylinder engages in the groove at the lower end of the high-pressure cartridge case primer. Then, the pry bar cylinder extends downward, driving the pry bar downward through the connecting rod. Using the lever principle, the high-pressure cartridge case is pried upward. Then, the slot cylinder retracts, and the high-pressure cartridge case falls into the receiving slide below. The receiving slide is an inclined surface with a groove at the bottom of the inclined surface. The cartridge case falls into the collection box along the groove.

[0022] Finally, it should be noted that the above preferred embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although the utility model has been described in detail through the above preferred embodiments, those skilled in the art should understand that various changes can be made to it in form and detail without departing from the scope defined by the claims of this utility model.
