[0051] The working principle of the present invention is as follows: In the initial state, the piston rod of the lifting cylinder is placed in a downward extended state; the piston rod of the brake cylinder is placed in a retracted state, releasing the position lock of the rack, and the piston rod of the reset cylinder is placed in an extended state, thereby pushing the push rod to rotate and squeeze the spring and separate the tooth block from the rack. The rack slides down to the lowest position under the action of gravity, and the piston rod of the clamping cylinder is placed in a retracted state. The wedge block is in a low position along with the piston rod of the clamping cylinder. The sliding block that slides with the wedge block through the inclined surface can only move in the horizontal direction under the restriction of the horizontal support plate and the cover plate. Therefore, it keeps in contact with the wedge block under the action of the reset spring or the dovetail groove and the dovetail protrusion, thereby generating a larger clamping gap between the vertical part of the pressure block connected to the sliding block and the fixed base for the material strip to be processed to pass through; The sheet material strip to be processed is vertically mounted on the support plate, and the upper part of the material strip passes through the loading through hole on the horizontal support plate and extends upward to the clamping gap between the fixed base and the vertical part of the pressing block; When the material lifting operation is performed, the piston rod of the reset cylinder contracts, and the tooth block keeps meshing with the rack under the action of the spring. The piston rod of the lifting cylinder contracts upward, driving the tooth block installed on the connecting strip to move upward, and the tooth block further pulls the rack installed with the support plate to move up a distance H, and sends the material strip that moves up a distance H with the support plate to the processing position. At this time, the piston rod of the clamping cylinder is driven to extend upward, and the wedge block moves upward with the piston rod of the clamping cylinder. The sliding block that slides with the wedge block through the inclined surface can only move in the horizontal direction under the restriction of the horizontal support plate and the cover plate. Therefore, it moves toward the material strip direction under the push of the wedge block, so that the pressure block connected to the sliding block The vertical part moves toward the material belt and clamps the material belt. In order to ensure the stability of the material belt during processing and prevent the rack from moving downward, the piston rod of the brake cylinder is driven to extend, thereby locking the rack through the pressure block thereon, and driving the piston rod of the reset cylinder to extend downward again. In the process of the gear block moving down and resetting with the piston rod of the reset cylinder, the rack remains motionless under the action of the locking cylinder, and the gear block repeatedly contracts in the horizontal direction under the cooperation of the inclined surface between the first tooth body and the second tooth body and the action of the spring while moving downward, so that the milling debris on the rack is cleared while the gear block moves down and resets, avoiding adverse interference caused by the accumulation of splashing milling debris; The material strip in a stable clamping state is subjected to milling and other processing. After one product is processed and removed manually or mechanically, the above-mentioned material lifting operation is repeated in a cycle until the entire material strip is processed and multiple products are obtained.

[0052] When the above-mentioned automated processing jig for sheet profiles is used, it can not only ensure the close fit between the tooth body and the rack during the material lifting process, but also realize the downward movement and resetting of the tooth block when the rack is stationary, thereby realizing multiple continuous material lifting operations. It can also apply a stable and balanced surface clamping force to the material strip when processing the material strip and can realize the rapid withdrawal of the clamping force, thereby facilitating multiple continuous material lifting operations on the material strip, and can maintain the stability of the material strip in the vertical direction during the downward movement and resetting of the tooth block, thereby improving the efficiency and stability of continuous processing of the material strip.

[0053] The above embodiments are only for illustrating the technical concept and features of the present invention, and their purpose is to enable people familiar with the technology to understand the content of the present invention and implement it accordingly, and they cannot be used to limit the protection scope of the present invention. Any equivalent changes or modifications made according to the spirit of the present invention should be included in the protection scope of the present invention.

At least one horizontally arranged brake cylinder (12) is installed on the side surfaces of the two guide bars (4) that are away from each other. The piston rod of each brake cylinder (12) correspondingly penetrates into the guide bar (4) and is installed with a pressure block (13). When the piston rod of the brake cylinder (12) is in an extended state, the pressure block (13) is in compression contact with the side surface of the rack (5).

2. The automated processing jig for sheet profiles according to claim 1, characterized in that: A plurality of first teeth (51) arranged vertically are sequentially arranged on the surface of the rack (5) facing the tooth block (6); the lower surface of each of the first teeth (51) arranged in a triangle is a horizontal surface, and the other surface is an inclined surface, and the angle between the inclined surface and the horizontal surface is 40° to 70°; the upper surface of the second teeth (61) on the tooth block (6) that cooperates with the first teeth (51) is a horizontal surface.

3. The automated processing jig for sheet profiles according to claim 1 or 2, characterized in that: A push rod (19) is rotatably mounted at the lower portion of the support seat (9), the lower end of the push rod (19) extending downward from the bottom surface of the support seat (9), the upper end of the push rod (19) extending into a mounting hole (20) vertically opened on the lower surface of the middle portion of the movable block (10), when the lower end of the push rod (19) rotates in a direction approaching the rack (5), the upper end of the push rod (19) pushes the movable block (10) to move in a direction away from the rack (5).

4. The automated processing jig for sheet profiles according to claim 3, characterized in that: A pin shaft (21) passes through a through hole formed in the middle of the push rod (14) and is rotatably connected to the inner wall of the through hole. Both ends of the horizontally extending pin shaft (21) are mounted on a support seat (9).

5. The automated processing jig for sheet profiles according to claim 3, characterized in that: A reset cylinder (31) for cooperating with the push rod (19) is installed at the lower part of the base plate (1).
