Description

Technical Field

[0001] The utility model relates to the field of cutting devices, in particular to a synchronous cutting device. Background Art

[0002] In industrial production activities, in order to improve production efficiency, some materials (such as pipes, sheets, etc.) are usually processed continuously. At this time, the length or width of the processed materials is usually long, which is not convenient for storage and transportation of the materials. Therefore, after the initial processing of the materials, they need to be cut to obtain products of a certain length or width. In the actual production process, a cutting device is usually used to cut the processed materials to improve the efficiency of material cutting.

[0003] For example, a patent application entitled "A pipe positioning and cutting device" (publication number CN110802268B) includes a device bracket, a power mechanism, a rotating screw, a clamping mechanism, a positioning rail, a pushing frame and a cutting mechanism. The power mechanism drives the rotating screw to rotate, and the rotating screw drives the clamping mechanism to slide on the device bracket through a thread. When the clamping mechanism slides to a specified distance, the clamping mechanism pushes the positioning rail to move downward through a positioning sliding block. The positioning rail moves downward to cut off the transmission between the power mechanism and the rotating screw, and the positioning rail moves downward to connect the transmission between the power mechanism and the cutting mechanism, and the cutting mechanism cuts the pipe.

[0004] However, in order to ensure the accuracy of the material cutting position and the flatness of the cutting edge during the cutting process, the existing cutting device needs to interrupt the material conveying process during the cutting process, and fix and position the material and the cutting blade while the material is standing still. This can easily lead to interruptions in the material conveying process, affecting the continuity of the material transportation on the material production line before and after the cutting operation, resulting in the inability to continuously convey the material, resulting in a large amount of idle time on the material conveying line, and reducing the overall material production efficiency. Utility Model Content

[0005] The utility model is intended to provide a synchronous cutting device to solve the technical problem in the prior art that the material conveying process needs to be interrupted during the cutting process, and the material and the cutting blade are fixed and positioned while the material is stationary, resulting in the inability to continuously convey the material, causing a large amount of idle time on the material conveying line and reducing the overall production efficiency of the material.

[0006] To achieve the above-mentioned purpose, the utility model adopts the following technical scheme: it includes a base, the base is provided with a cutting unit which reciprocates along its length direction, and a first guide group fixed on the base, the first guide group is located at the front end of the cutting unit, the cutting unit includes a cutting frame and a second guide group, the second guide group is located at the front end of the cutting frame, and the second guide group is arranged relative to the first guide group, the cutting frame is provided with a cutting part for cutting materials, the cutting part includes a blade and two groups of clamping plate groups, the blade is located between the two groups of clamping plate groups, the central axis of the blade is parallel to the length direction of the base, each group of clamping plate groups includes a fixed clamping block and a movable clamping block, one end of the fixed clamping block is fixed to the side of the cutting frame close to the blade, the movable clamping block and the fixed clamping block are arranged opposite to each other, the movable clamping block can move in the direction close to or away from the fixed clamping block, and the facing surfaces of the movable clamping block and the fixed clamping block are provided with a fixing groove, and the fixing groove is used to clamp and fix the cutting material.

[0007] The principle and advantage of this scheme are: during installation, the device is installed between the material conveying lines, and the reciprocating movement direction of the cutting unit is consistent with the conveying direction of the material. The material to be cut is passed through the first guide group and the second guide group, and the clamping plate group is aligned with the position of the material, so that the clamping plate can clamp and fix the material. During cutting, the cutting unit is located at the front end of the base, where the front end is one end of the material input base, the clamping plate clamps and fixes the material, and the cutting unit moves synchronously with the material along the slide rail. During the movement, the motor drives the blade to rotate to cut the material. After the cutting is completed, the clamping plate releases the clamping of the material, and the cutting unit moves to the front end of the base in the opposite direction of the feeding, ready to cut the material again. In this way, the material is cut back and forth in an uninterrupted conveying process.

[0008] In this solution, a slide rail is arranged on the base so that the cutting unit can keep consistent with the conveying speed of the material during the cutting process, so that the material can be cut while being conveyed and moved, which can avoid stopping the conveying of the material during cutting and affecting the efficiency of the material processing process; at the same time, the slide rail is parallel to the feeding direction to ensure the stability of the sliding process of the cutting unit, and clamping plates are arranged on both sides of the blade to fix the material, so as to ensure the fixation of the relative position between the material and the blade during the cutting process, thereby improving the cutting effect of the cutting unit during the synchronous cutting process, and at the same time, fixing grooves are opened at the opposite positions between the clamping blocks to fix the material, thereby improving the circumferential wrapping of the clamping blocks on the material and ensuring the stability of the material during the cutting process.

[0009] A first guide group and a second guide group are respectively arranged on the base and the cutting unit, so that the material can maintain the stability of position and conveying direction under the support of the guide group when passing through the cutting device, so that the cutting unit can quickly align with the material during reciprocating cutting, thereby improving the accuracy of the device during operation.

[0010] Preferably, as an improvement, a slide rail is provided on the base, the extension direction of the slide rail is consistent with the length direction of the base, there are two slide rails, the two slide rails are parallel to each other and evenly distributed on one side of the base, and a connecting plate is provided at the bottom of the cutting unit, and the connecting plate is slidably connected to the base through the slide rail. When the cutting unit slides on the base along the slide rail, the stability of the cutting unit as a whole can be ensured, and the shaking or position shift of the cutting unit when sliding can be avoided, which will reduce the cutting accuracy of the cutting unit and affect the cutting effect of the material.

A transverse wheel group and a longitudinal wheel group are provided in each guide group, so that the guide group can perform fixed guidance on the circumference of the material to ensure the consistency of the material conveying direction.

[0013] Preferably, as an improvement, the cutting unit further includes a cooling part, which includes a first spray gun and a second spray gun; the first spray gun is located between the clamping plates and projected in the feeding direction, and is used to cool the material in the feeding direction; the second spray gun is located on one side of the blade, and the second spray gun is used to cool the blade. The cooling part cools the blade and the material during the cutting process, so as to avoid deformation at the cutting site caused by the increase in temperature of the material and the blade during the cutting process, thereby reducing the quality of the material.

[0014] Preferably, as an improvement, the cooling unit further comprises a baffle, which is located on the side of the clamping plate away from the blade, and the upper and lower ends of the baffle are bent toward the blade, so that the debris generated by the blade during cutting and the coolant sprayed by the cooling unit can be collected in a direction under the shielding effect of the baffle, thereby preventing the debris and coolant from splashing around during the cutting process and polluting the processing environment.

[0030] The specific implementation process is as follows:

[0031] When installing this device, it is installed in the conveying line after material processing, and the extension direction of the device is consistent with the feeding direction of the material; in this embodiment, the conveyed material is a metal pipe, and the two ends of the device are aligned with the conveying line of the pipe, so that the pipe can pass through the cutting unit during the conveying process.

[0032] When cutting the material, the cutting unit is moved to the front end of the base 1, the pipe enters the cutting device through the conveyor line and passes through the first guide group 4, the second guide group 5 and the clamping plate group in sequence, and continues to move along the original feeding direction. The cutting unit keeps the same speed as the material feeding speed on the base 1 and moves synchronously. The cylinder 302 pushes the clamping block to clamp the pipe.

After completing the cutting of the current position of the pipe, the blade 301 stops rotating and the electric telescopic rod drives the blade 301 to move away from the pipe. The cylinder 302 drives the clamping block to move in the direction away from the pipe, and moves the cutting unit to the front end of the base in the direction opposite to the feeding direction, and prepares for the next cutting. When cutting, the cutting unit can adjust the rotation speed of the blade 301, the speed at which the cutting unit moves to the front end of the base 1, and the interval time between two cuts according to the length of the material to be cut. The specific interval time between the two cuts can be calculated based on the moving speed of the material to calculate the interval time between the required cutting lengths, and the time for moving the material of the required cutting length is obtained, so that the cutting unit can cut materials of different length requirements.

[0033] In this solution, the cutting unit is moved synchronously with the material along the feeding direction and the material is cut during the movement, so that the segmented cutting of the material is completed without interrupting the material conveying process, thereby ensuring the efficiency of the material production process; and during the production process, the material will be conveyed at a uniform speed, which is convenient for the cutting unit to calculate the cutting position according to the material conveying speed, avoiding errors in the cutting position caused by the stopping of the material conveying during cutting, thereby reducing the consistency of the material cutting length.

[0034] The first guide and the second guide group 5 are respectively provided in the base 1 and the cutting unit, and the material is clamped and fixed by the clamping plate group during cutting, so that the material can be transported into the cutting device and the cutting point to ensure the stability of the position, avoiding the displacement of the material during the cutting process, resulting in the deviation of the material cutting surface, and reducing the quality of the material cutting surface. At the same time, guide groups or guide rollers 8 are provided at both ends of the cutting unit to ensure that the material after cutting can continue to move along the feeding direction, improve the consistency and stability of the material conveying direction when passing through the cutting unit, and ensure the operation effect of the cutting unit.
