Description

Technical Field

[0001] The utility model relates to the technical field of shearing machines, in particular to a shearing machine for elevator production. Background Art

[0002] An elevator is a permanent transportation device that serves several specific floors in a building, with its car running on at least two rigid tracks perpendicular to the horizontal plane or with an angle of inclination less than 15° to the plumb line. There are also step-type ones, with the treads mounted on the tracks and running continuously, commonly known as escalators or moving walkways. Fixed lifting equipment that serves specified floors requires cutting of the plates during the elevator production process, so a shearing machine for elevator production is used.

[0003] The Chinese patent with the authorization publication number CN220805636U discloses a shearing machine, including a frame, a shearing mechanism installed on the surface of the frame, and a driving mechanism installed on one side of the frame for driving the shearing mechanism, and the surface of the frame is also provided with a guide conveying component. The present application provides a guide conveying component, and before shearing the plate, two guides are brought closer to each other by turning the handle, so that they form a resistance to the outer side of the plate. During the process of moving and cutting the plate, the plate itself will not be offset, and through the cooperation of the driving component, it can be adaptively adjusted according to plates of different sizes, thereby improving the scope of application of the device.

[0004] Although the shearing machine mentioned above can be adaptively adjusted according to plates of different sizes, thereby improving the application range of the device, the plate is clamped only by the side plates on both sides of the device. If a thin plate is encountered, it is difficult to achieve effective clamping from both sides, which can easily cause instability of the plate during the cutting process and affect the cutting accuracy. For this reason, we propose a shearing machine for elevator production. Utility Model Content

[0008] An upper cutter is installed in the middle of the upper part of the base, both sides of the upper part of the upper cutter are connected with hydraulic push rods, a lower cutter is arranged on one side below the upper cutter, and both sides of the lower cutter are connected with linkage plates, and a lifting hydraulic rod is connected below the linkage plate;

[0009] A nut seat is installed below the translation seat, a transmission screw rod is installed inside the nut seat, and one end of the transmission screw rod is connected to a driving motor.

[0010] Preferably, the base further comprises:

[0011] Graduation lines are arranged at two ends of the upper end surface of the base and are evenly distributed between the graduation lines.

[0012] Preferably, a telescopic structure is formed between the lifting push rod and the lifting block, the lifting block is fixedly connected to the limiting ring, and the positioning seat passes through the interior of the limiting ring.

[0013] Preferably, a telescopic structure is formed between the hydraulic push rod and the upper cutter, and the upper cutter and the lower cutter are parallel to each other, and the lifting hydraulic rod forms a telescopic structure with the lower cutter through a linkage plate.

[0014] Preferably, a rotating structure is formed between the driving motor and the transmission screw rod, and the transmission screw rod passes through the interior of the nut seat.

[0015] Preferably, the nut seat is fixedly connected to the translation seat, and the translation seat is symmetrically distributed about the vertical center line of the base.

[0016] Compared with the prior art, the utility model provides a shearing machine for elevator production, which has the following

[0017] Beneficial effects:

[0018] The utility model can drive the lifting block to move vertically through the lifting push rod, and the limit ring can limit the lifting block, so that the plate can be positioned on the positioning seat through the cooperation of the lifting block and the translation seat, avoiding the problem that the plate is clamped only by the side plates on both sides of the device.
