Description

Technical Field

[0001] The utility model belongs to the technical field of profile cutting and processing, and in particular relates to a profile fixing and clamping device for a profile cutting machine. Background Art

[0002] Profile refers to a solid straight bar with a certain cross-sectional shape and size formed by plastic processing of metal. Profiles come in a wide variety of specifications and are widely used. They play a very important role in rolling production. In the process of profile production and processing, multiple processes are required, among which the cutting process is a very common process step. Profile cutting machines are required for cutting. Profile cutting machines, also called grinding wheel saws, are suitable for construction, hardware, petrochemical, mechanical metallurgy, and water and electricity installation departments. Profile cutting machines are a common equipment that can cut metal square flat tubes, square flat steel, I-beams, channel steel, carbon steel, and tubes.

[0003] The existing profile cutting machine fixes the profile workpiece by driving the movable clamping plate to move toward the fixed clamping plate through the rotation of the screw. This fixing method only clamps the two sides of the profile. When cutting, the cutting wheel moves up and down, which generates a downward force applied to the profile workpiece. Therefore, the profile is prone to warping. When the profile is warped, the cutting accuracy is reduced and safety accidents are prone to occur. Utility Model Content

[0004] The purpose of the utility model is to provide a profile fixing and clamping device for a profile cutting machine, so as to solve the problem proposed in the above background technology that the fixation of the profile workpiece on the existing profile cutting machine is achieved by driving the movable clamping plate to lean against the fixed clamping plate by the rotation of the screw. This fixing method only clamps the two sides of the profile. When cutting, since the cutting wheel moves up and down, a downward force is applied to the profile workpiece, so the profile is prone to warping. When the profile is warped, the cutting accuracy is reduced and safety accidents are prone to occur.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a profile fixing and clamping device for a profile cutting machine, comprising a base, bolts are threadedly installed at the four corners of the base, a fixed clamping plate and a side plate are fixedly installed on the upper surface of the base, a screw is threadedly installed on the side plate, a hand wheel is fixed to one end of the screw, a rotating shaft is fixedly installed on the other end of the screw, a movable clamping plate is rotatably installed on the end of the rotating shaft, a groove is provided on the side of the fixed clamping plate close to the movable clamping plate, a plurality of guide rods are slidably installed on the fixed clamping plate, a top plate is fixed to one end of the guide rod, and an outer sleeve of the guide rod is provided with two ends respectively connected to the groove The cam is provided with a plurality of springs, each of which is connected to the inner wall and the top plate, and a wedge plate is fixedly installed on the other end of the guide rod, and a wedge plate is matched with a wedge plate on the inclined surface of the wedge plate.

A limiting rod is fixedly installed in the frame, and the sliding block slides on the outer surface of the limiting rod. A connecting plate is fixedly installed on the side of the sliding block, and a locking piece is provided between the two connecting plates. A pressure plate is fixed on the end of the connecting plate away from the sliding block, and a plurality of limiting rods are fixed on the upper surface of the fixed card plate, and the connecting plate is slidably installed on the outer surface of the limiting rod at the corresponding position.

[0006] The above scheme is adopted, by setting a fixed clamping plate and a movable clamping plate for use with a screw, the screw rotates to drive the movable clamping plate to approach the fixed clamping plate to achieve side clamping, and at the same time, the top plate is used in conjunction with the guide rod and wedge plate one and wedge plate two, so that while the side is clamped, the pressure plate will move downward synchronously to achieve longitudinal clamping. Therefore, the phenomenon of warping of the profile workpiece during the cutting process can be effectively avoided, good cutting operation accuracy can be guaranteed, and safety problems caused by the warping of the profile workpiece can be avoided. By setting a sliding block to slide on the surface of the second limit rod and locking it with a locking piece, the initial position of the pressure plate can be adaptively adjusted, so that it can be adaptively adjusted according to the thickness specification of the profile tool, with a wide range of applications and perfect functional diversity.

[0007] As a preferred embodiment, rubber anti-slip pads are adhered to the opposite surfaces of the fixed clamping plate and the movable clamping plate.

[0008] By adopting the above solution, the provision of the rubber anti-skid pad can ensure that the fixed clamping plate and the movable clamping plate have a good anti-skid effect when fixing and clamping the profile workpiece, thereby improving the fixing and clamping effect.

[0011] As a preferred embodiment, telescopic sleeves are fixed to the left and right sides of the side plate, the telescopic sleeves are sleeved on the outside of the screw, and the ends of the two telescopic sleeves that are away from each other are fixedly connected to the movable clamping plate and the hand wheel respectively.

[0012] By adopting the above scheme, the screw can be isolated from the outside world by using the setting of the telescopic sleeve, so as to prevent the debris generated during the cutting process from entering the screw thread gap and affecting the normal rotation of the screw, thereby achieving a good protective effect.

[0013] As a preferred embodiment, a plurality of trapezoidal grooves are formed on the inclined surface of the wedge plate 1, a plurality of trapezoidal blocks are fixedly mounted on the inclined surface of the wedge plate 2, and the trapezoidal blocks are slidably mounted on the inner walls of the trapezoidal grooves.

[0014] By adopting the above solution, the trapezoidal groove is used in conjunction with the trapezoidal block, so that the wedge plate 2 can stably move up and down when the wedge plate 1 moves horizontally.

[0015] As a preferred embodiment, the locking member includes a fixed plate installed on the surface of the connecting plate, a locking rod sliding through the fixed plate, a linkage plate installed at one end of the locking rod, and a spring 1 sleeved on the outside of the locking rod, and a plurality of locking holes for inserting the locking rod are opened on the limit rod 2, and the two ends of the spring 1 are respectively fixedly connected to the fixed plate and the linkage plate.

[0016] By adopting the above solution, after the sliding block slides on the surface of the second limiting rod, the elasticity of the first spring is used to drive the locking rod to be inserted into the locking hole at the corresponding position, so that the position of the pressure plate can be adjusted.

The screw rod rotates to drive the movable clamping plate to approach the fixed clamping plate to achieve side clamping. At the same time, the top plate is used in cooperation with the guide rod and the wedge plate 1 and the wedge plate 2, so that the pressure plate will move downward synchronously to achieve longitudinal clamping while the side is clamped. Therefore, the profile workpiece can be effectively prevented from warping during the cutting process, ensuring good cutting operation accuracy and avoiding safety problems caused by the profile workpiece warping.

[0019] The profile fixing and clamping device for the profile cutting machine is configured with a sliding block that slides on the second surface of a limit rod and is used in conjunction with a locking piece for locking.
