Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of drilling machines, in particular to a guardrail edge strip punching machine. BACKGROUND

[0002] Punching is a very common operation for the processing of profiles such as guardrail edge strips. After punching, the edge strips can be assembled into guardrails through bolts, and in order to prevent the profile from moving during punching, a clamp is generally used to clamp and fix the profile.

[0003] Through retrieval, the Chinese invention patent with application number 202322085561.3 discloses an automatic punching machine for aluminum profiles. The aluminum profile is clamped by two sets of clamping plates, and drilling is performed by lowering the drilling machine. When multiple punchings are required for the aluminum profile, the external power supply of the first motor is connected, the first motor is started to drive the incomplete gear to rotate, so that the incomplete gear can drive the rack plate to move the aluminum profile. After the incomplete gear rotates to a certain angle, it is no longer meshed with the rack plate, so that the movement distance of the rack plate is fixed. At the same time, the force of the drill bit on the aluminum profile is from top to bottom, so the position of the rack plate will not move.

[0004] The inventor believes that in the above-mentioned patent technology, the movement of the clamping device can automatically feed the profile, but during drilling, the drill bit of the drilling machine must exert a certain pressure on the profile to smoothly drill into the profile. In the above-mentioned patent technology, the clamping device cannot be kept below the drilling machine, so that during punching, the profile below is prone to tilting due to the lack of support. In addition, in the field of profile punching, drill cuttings will fly everywhere, which is a common problem.

[0005] Therefore, the present application proposes a guardrail edge strip punching machine which is more stable during drilling. SUMMARY

[0006] In view of the above situation, in order to overcome the defects of the prior art, the present application provides a guardrail edge strip punching machine to solve the above problems.

[0007] In order to achieve the above-mentioned purpose, the guardrail edge strip punching machine comprises a drilling platform, a clamp arranged on the surface of the drilling platform and a drilling machine arranged above the drilling platform, the clamp comprises three groups of clamping mechanisms arranged in sequence on the drilling platform, the two clamping mechanisms located on the outer side are synchronously moved in the length direction of the profile to constitute a moving pair for moving the profile, the clamping mechanism located in the middle constitutes a fixed pair for fixing the profile, and the three groups of clamping mechanisms are specifically arranged as follows: the clamping mechanism comprises a bottom plate, a fixed baffle is fixed on one side of the bottom plate, a gas cylinder is fixed on the other side of the bottom plate, and a clamping plate is connected to the gas cylinder, the bottom plate of the clamping mechanism located in the middle position is fixed on the surface of the drilling platform, and the bottom plates of the two clamping mechanisms located on the outer side are slidingly arranged on the surface of the drilling platform.

[0008] Compared with the prior art, the guardrail edge strip punching machine has the following advantages: 1) the profile is moved by the moving pair to realize automatic feeding, when punching, the support rollers on the moving pair support from both sides of the bottom of the profile, the fixed pair supports at the position of the profile bottom for punching, and the three-point support mode makes the punching more stable; 2) when punching, the top and both sides of the telescopic cover are enclosed with the fixed baffle and the clamping block to form a relatively closed space, then the drill bit of the drilling machine is moved downward to drill a hole, thereby preventing drill chips from splashing, and solving the common problem that drill chips easily splash everywhere when the existing punching machine punches.

[0014] The specific embodiments of the application will be further described below in conjunction with the accompanying drawings. Figures 1-3 The guardrail edge strip punching machine of the application comprises a drilling platform 10, a clamp arranged on the surface of the drilling platform 10 for clamping the profile and a drilling machine 20 arranged above the drilling platform 10 for punching the clamp, which constitutes the basic punching machine structure, and will not be described here. The main improvement of the application lies in that:

[0015] The clamp comprises three sets of clamping mechanisms 30 arranged in sequence on the drilling table 10, the two clamping mechanisms 30 on the outer side move synchronously in the length direction of the profile to form a moving pair for moving the profile, the clamping mechanism 30 in the middle position is fixed in position to form a fixed pair for fixing the profile, in use, the moving pair clamps the profile to move, stops when moving to the position below the drilling position of the drilling machine, then the fixed pair fixes the profile, and drilling is performed by the drilling machine 20, during the drilling process, the moving pair releases the profile and returns to the original position, after the drilling is completed, the fixed pair releases the profile, and the moving pair clamps the profile again and moves to the position below the drilling position, the above-mentioned actions are repeated until the punching is completed, the profile is moved by the two clamping mechanisms 30 to realize automatic feeding, and the fixed pair for supporting the profile always supports directly below the drilling position when punching, so that the profile has better stability when punching.

[0016] It can be understood that when it is necessary to completely punch through the profile, a punching accommodation groove should be arranged on the bottom plate 31 of the fixed pair.

[0017] The three sets of clamping mechanisms 30 are specifically arranged as follows: the clamping mechanism 30 comprises a bottom plate 31, a fixed baffle 32 is fixed on one side of the bottom plate 31, a gas cylinder 33 is fixed on the other side of the bottom plate 31, a clamping block 34 is connected to the gas cylinder 33, the bottom plate 31 of the clamping mechanism 30 in the middle position is fixed on the surface of the drilling table 10, and the bottom plate 31 of the two clamping mechanisms 30 on the outer side is slidingly arranged on the surface of the drilling table 10, in use, the profile is first sent into the gap between the fixed baffle 32 and the clamping block 34 of the moving pair, the profile is clamped by the gas cylinder 33 of the moving pair being elongated, then the moving pair drives the profile to move to the drilling position, the gas cylinder 33 of the fixed pair is elongated to drive the clamping block 34 to clamp the profile, drilling is performed by the drilling machine 20, during the drilling process, the moving pair returns to the original position and clamps the profile, after the drilling of the drilling machine 20 is completed, the moving pair moves the profile to the drilling position again, and the above-mentioned actions are repeated until the drilling is completed.

[0018] The surface height of the bottom plate 31 of the clamping mechanism 30 in the middle position is higher than the height of the bottom plate 31 of the two clamping mechanisms 30 on the outer side, so that, during the drilling, the profile is fixed by the fixed pair, the moving pair can be moved to the original position and clamp the profile first, and after the drilling machine 20 completes one drilling, the profile can be quickly moved a distance.

[0019] In order to prevent the drilling debris from splashing during the drilling process, the telescopic cover 50 is vertically slidably arranged on the head of the drilling machine 20, the telescopic cover 50 is specifically a U-shaped structure, and the telescopic cover 50 is connected with the head of the drilling machine 20 through the spring 51, so that when the drilling machine 20 moves downward and drills, the lower end of the telescopic cover 50 will first contact the bottom plate 31, so that the top and both sides of the telescopic cover 50 are enclosed with the fixed baffle 32 and the clamping block 34 to form a relatively closed space, and then the drill bit of the drilling machine 20 moves downward and drills to prevent the drilling debris from splashing, and the spring 51 is compressed during the drilling process, and after the drilling is completed, the drill bit of the drilling machine 20 moves upward, and under the action of the spring 51, the telescopic cover 50 moves downward relative to the drill bit to return to the initial position.

[0020] In order to facilitate the collection of the drilling debris, the side surface of the telescopic cover 50 is connected with the dust collector 53 through the connecting pipe 52, and the dust collector 53 is fixed on the surface of the drilling platform 10, during the drilling process, the drilling debris is blocked in the space enclosed by the telescopic cover 50, the fixed baffle 32 and the clamping block 34, and the drilling debris is extracted through the dust collector 53, so that the drilling debris can be conveniently cleaned in time to prevent the drilling debris from falling into the gap on the surface of the drilling platform 10 and being difficult to clean.

[0021] In order to support the bottom of the profile from both sides of the punching position, solve the problem of instability of the profile punching process caused by only one support point mentioned in the background art, the bottom plate 31 of the two clamping mechanisms 30 located on the outside is provided with the supporting roller 35, so that the profile can be supported from the bottom through the supporting roller 35, and during the drilling process, the profile is fixed in position through the action of the fixed pair, and the supporting roller 32 on the bottom plate 31 of the moving pair rolls on the bottom surface of the profile, which also plays a supporting role.
