Description

Technical Field

[0001] The present application relates to the technical field of pipe punching, and more specifically, to a trolley pipe punching machine. Background Art

[0002] A trolley is a tool used to carry objects. Pipe fittings are used in trolleys to increase the strength and stability of the structure. Pipe fittings are usually used to connect various parts of the trolley, such as the connection between the platform and the wheel frame. In order to allow the various pipe fittings to be connected to each other, holes are punched on them during processing.

[0003] In the related art, it is proposed that when punching a pipe with a punch press, the subsequent installation hole is often not located in the same straight line as the originally opened installation hole. For example, the patent with the prior art publication number CN214211905U provides a positioning device for punching pipes. The device is provided with a sliding block, a sliding plate, a positioning cylinder, a guide body and a placement plate. The sliding block can be moved on the slide plate and adjusted to the first hole position opened on the pipe body, so that the positioning cylinder and the guide body can enter the hole opened on the pipe body, and the fixed pipe fitting and the fixed hole fitting fix the orientation position of the pipe body, and the end without a hole is placed on the fixed block. The new installation hole formed by the punch is in the same straight line as the pre-opened installation hole.

[0004] Although the above-mentioned prior art solution can achieve the effect of opening multiple holes on the same horizontal line through the arrangement of a sliding block, a sliding plate, a positioning cylinder, a guide body and a placement plate, it still has the following defects: the fixed block is fixed, resulting in the tube body being unable to move, thereby failing to continuously open holes on the outside of the tube body, making the punching device relatively simple.

[0032] Loosen the fastening bolts 105 and pull the sliding frame 104 to one side so that the pipe body 109 can be mounted on the outside of the support rod 108. Measure the punching position according to the scale 107. When punching the first hole, the pipe body 109 rests against the top side of the sliding frame 104. The pipe body 109 is placed on the top of the support platform 106. The hole opened on the outside of the support rod 108 is concentric with the waste slide at the top of the support platform 106. Then use the fastening bolts 105 to fix the sliding frame 104, and drive the hydraulic rod 102 to extend and retract through the hydraulic cylinder 101, so that the punch head 103 punches holes on the outside of the pipe body 109.

[0033] Reference Figure 2 , Figure 3 and Figure 4 The driving mechanism includes a driving motor 2, a driving gear 201 is fixedly provided at the driving end of the driving motor 2, a gear ring 202 is meshed on the outer side of the driving gear 201, a bearing base 206 is rotatably provided on one end of the gear ring 202, a fixing rod 205 is penetrated at one end of the gear ring 202, a driving sleeve 204 is provided on the outer side of the fixing rod 205, a plurality of transmission connecting rods 203 are fixedly provided between the gear ring 202 and the driving sleeve 204, the fixing rod 205 penetrates and is fixedly provided on one side of the bearing base 206, a counterweight block 207 is fixedly provided on one end of the fixing rod 205, a motor bracket 208 is fixedly provided on the outer side of the driving motor 2, the motor bracket 208 is fixedly provided on one side of the bearing base 206, the driving gear 201 is rotatably provided on one side of the bearing base 206, and the bearing base 206 is fixedly provided on one side of the inner side of the stamping machine frame 1.

[0034] When drilling, the driving motor 2 in the driving mechanism is started, and the driving gear 201 can rotate. The rotation of the driving gear 201 drives the gear ring 202 to rotate. The rotation of the gear ring 202 drives the driving sleeve 204 to rotate through the transmission connecting rod 203, thereby driving the expansion mechanism 3 to obtain power for use.

[0035] Reference Figure 2 , Figure 3 and Figure 4 The expansion mechanism 3 includes a threaded arc plate 301, four threaded arc plates 301 are provided, the threaded arc plates 301 are threadedly connected to the inner side of the driving sleeve 204, a connecting column head 307 is slidably provided on the inner side of the threaded arc plate 301, four sliding grooves 308 are provided on the outer side of the connecting column head 307, a moving platform 302 is slidably provided on the inner side of the sliding groove 308, the moving platform 302 is fixedly provided at the end of the threaded arc plate 301, a fixed platform 305 is fixedly provided on the outer side of one end of the connecting column head 307, a connecting rod 303 is rotatably provided on the top of the moving platform 302 and the fixed platform 305, a supporting plate 304 is rotatably provided on the other end of the connecting rod 303, the connecting column head 307 is fixedly provided on one end of the fixed rod 205, the threaded arc plate 301 is slidably provided on the inner side of the sliding groove 308, a stable telescopic rod 306 is symmetrically fixedly provided on the bottom end of the supporting plate 304, and the stable telescopic rod 306 is fixedly provided on the outer side of the connecting column head 307.

[0036] The rotation of the drive sleeve 204 can drive the threaded arc plate 301 in the expansion mechanism 3 to move on the inner side of the slide groove 308. The movement of the threaded arc plate 301 drives the moving platform 302 to move, so that the angle between the connecting rods 303 will become smaller, so that the support plate 304 is close to the inner wall of the pipe body 109, thereby supporting and fixing the pipe body 109 to prevent the pipe body 109 from moving or shaking, thereby improving the punching accuracy. When multiple holes need to be opened on the outside of the pipe body 109, the driving gear 201 can drive the gear ring 202 to rotate in the reverse direction, and the support plate 304 will shrink, so that the pipe body 109 can move freely.

[0037] Working principle: Loosen the fastening bolts 105 and pull the sliding frame 104 to one side so that the pipe body 109 can be sleeved on the outside of the support rod 108. Measure the punching position according to the scale 107. When punching the first hole, the pipe body 109 is against the top side of the sliding frame 104. The pipe body 109 is placed on the top of the support platform 106. The hole opened on the outside of the support rod 108 is concentric with the waste slide at the top of the support platform 106. Then use the fastening bolts 105 to fix the sliding frame 104, and drive the hydraulic rod 102 to extend and retract through the hydraulic cylinder 101, so that the punch head 103 punches holes on the outside of the pipe body 109. When punching holes, start the drive motor 2 in the drive mechanism, and the drive gear 201 can rotate. The rotation of the drive gear 201 drives the gear ring 202 to rotate, and the gear ring 2 The rotation of 02 drives the driving sleeve 204 to rotate through the transmission connecting rod 203. The rotation of the driving sleeve 204 can drive the threaded arc plate 301 in the expansion mechanism 3 to move on the inner side of the slide groove 308. The movement of the threaded arc plate 301 drives the moving platform 302 to move, so that the angle between the connecting rods 303 will become smaller, so that the support plate 304 is close to the inner wall of the pipe body 109, and then supports and fixes the pipe body 109 to prevent the pipe body 109 from moving or shaking, thereby improving the punching accuracy. When multiple holes need to be opened on the outside of the pipe body 109, the driving gear 201 can drive the gear ring 202 to rotate in the reverse direction, and the support plate 304 will shrink, and then move the pipe body 109, and measure the punching position according to the scale 107, so as to achieve the effect of continuous punching and improve work efficiency.
