Technical Field
[0001] The invention relates to a sizing machine, in particular to a sizing machine used for shearing steel materials. Background Art
[0002] Rolled steel will be cut into different lengths as needed. The existing equipment for measuring steel size is relatively complex in structure, and the size adjustment steps are cumbersome. In addition, after the size is adjusted, there is a large error between the fixed point and the set position of the equipment, resulting in low accuracy in controlling the cutting length of the steel.

[0006] A synchronous shaft is provided at the rear of the bottom of the crank, and an adjusting shaft passes through the crank. The synchronous shaft is connected to the top of the baffle by a connecting rod, and the connecting rod and the baffle are connected by a pin shaft. The connecting rod is mounted on the adjusting shaft, and a key slot is provided on the adjusting shaft. During the rotation of the adjusting shaft, when the connecting rod falls into the key slot, the horizontal position of the baffle moves downward.
[0007] An indicator plate is arranged on the side of the roller, and the top of the indicator plate points to the scale.
[0008] The beneficial effects are as follows: the structural design of the present invention is reasonable and ingenious, the roller is used to drive the cut-to-length trolley to move forward and backward on the beam, and the cut-to-length trolley is moved to the corresponding scale position according to the required length of the steel. At this time, according to the corresponding positions of the first clamping tooth and the second clamping tooth and the fixed rack, the clamping tooth that can be engaged with the fixed rack is retracted and engaged to fix the position of the cut-to-length trolley, and the positioning is more accurate. The baffle cylinder pushes the crank to move the baffle down, and the steel stops when it encounters the baffle. The rear shearing machine shears the steel of the set length, which is convenient and quick to use. BRIEF DESCRIPTION OF THE DRAWINGS
[0009] The present invention will now be described by way of example with reference to the accompanying drawings, in which:
[0010] Figure 1 It is a schematic diagram of the structure of the present invention;
[0011] Figure 2 is a schematic diagram of the structure of the cut-to-length trolley;
[0012] Figure 3 It is a schematic diagram of the connection structure between the baffle and the crank. DETAILED DESCRIPTION
[0013] All features disclosed in this specification, or steps in all methods or processes disclosed, except mutually exclusive features and / or steps, can be combined in any manner.
[0014] Any feature disclosed in this specification (including any additional claims, abstract and drawings), unless otherwise stated, may be replaced by other equivalent or alternative features with similar purposes. That is, unless otherwise stated, each feature is only an example of a series of equivalent or similar features.
[0015] like Figure 1 The length-cutting machine shown in the figure comprises a beam 1, a scale 3 is arranged on the side of the beam 1, a fixed rack 4 is arranged at the bottom of the beam 3, and a length-cutting trolley 2 is mounted on the beam 1. Figure 2 As shown, the cut-to-size trolley 2 includes a frame 21, a plurality of rollers 29 are provided on the top of the frame 21, the rollers 29 are connected to the reducer, the frame 21 is connected to the beam 1 through the rollers 29, a crank 23 is provided on the frame 21, the bottom of the crank 23 is connected to the baffle 24, the center of the crank 23 is connected to the frame 21 through a rotating shaft, the top of the crank 23 is connected to the baffle cylinder 22, and the baffle cylinder 22 is connected to the frame 21.
[0016] A first latching tooth 26 is provided in front of the frame 21, and the center of the first latching tooth 26 is connected to the frame 21 through a rotating shaft. A rack is provided on the top end surface of the first latching tooth 26, and the bottom is connected to the first cylinder 25, and the first cylinder 25 is arranged on the frame 21; a second latching tooth 28 is provided at the rear of the frame 21, and the second latching tooth 28 is connected to the frame 21 through a rotating shaft. A rack is provided on the top end surface of the second latching tooth 28, and the bottom of the rack is connected to the second cylinder 27, and the second cylinder 27 is arranged on the frame 21.
[0017] like Figure 3As shown, a synchronization shaft 211 is provided at the rear of the bottom of the crank 23, and an adjustment shaft 212 passes through the crank 23. The synchronization shaft 211 is connected to the top of the baffle 24 by a connecting rod 213, and the connecting rod 213 and the baffle 24 are connected by a pin shaft. The connecting rod 213 is mounted on the adjustment shaft 212, and a key groove is provided on the adjustment shaft 212. During the rotation of the adjustment shaft 212, when the connecting rod 213 falls into the key groove, the baffle 24 moves downward in horizontal position.
[0018] An indicator plate 210 is disposed on the side of the roller 29 , and the top of the indicator plate 210 points to the scale 3 .
[0019] The structural design of the present invention is reasonable and ingenious. The roller is used to drive the cut-to-length trolley to move forward and backward on the beam. The cut-to-length trolley is moved to the corresponding scale position according to the required length of the steel. At this time, according to the corresponding positions of the first clamping tooth and the second clamping tooth and the fixed rack, the clamping tooth that can be engaged with the fixed rack is retracted and engaged to fix the position of the cut-to-length trolley. Since the distance between the first clamping tooth and the second clamping tooth is set to n+1 / 2 teeth, the positioning of the cut-to-length trolley is more accurate. The baffle cylinder pushes the crank to move the baffle downward. When the steel meets the baffle, it stops. The rear shearing machine shears the steel of the set length. The use is convenient and quick.
[0020] The present invention is not limited to the above-mentioned specific embodiments, but extends to any new features or any new combination disclosed in this specification, as well as any new method or process steps or any new combination disclosed.
